PART I
Item 1. Business.
          Included in this report, exhibits and associated documents are “forward-looking” statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, as well as historical information. Although we believe that the expectations reflected in such forward-looking statements are reasonable, we can give no assurances that such expectations reflected in such forward-looking statements will prove to be correct. Our actual results could differ materially from those anticipated in forward-looking statements as a result of certain factors, including matters described in the section titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations.” Forward-looking statements include those that use forward-looking terminology, such as the words “anticipate,” “believe,” “estimate,” “expect,” “hope,” “intend,” “may,” “project,” “plan,” “should,” and similar expressions, including when used in the negative. Although we believe that the expectations reflected in these forward-looking statements are reasonable and achievable, such statements involve risks and uncertainties and no assurance can be given that the actual results will be consistent with these forward-looking statements.
          Unless the context otherwise requires, “Lime Energy,” the “Company,” “we,” “our,” “us” and similar expressions refers to Lime Energy Co. and its subsidiaries.
Overview
          We are a provider of energy services and technologies that improve the energy efficiency of our clients’ facilities and reduce their ongoing maintenance costs. Services we offer include the design, engineering and installation of energy efficient lighting systems and energy engineering consulting. We also market a proprietary line of controllers that provide intelligent control and continuous monitoring of HVAC and lighting equipment via wireless communication technology to reduce energy usage and improve system reliability.
History
          Our business has evolved substantially over time. In December 2006, we discontinued the marketing of what had been our original core product and, through an acquisition, launched our Energy Services business in June 2006. Through both organic growth and additional acquisitions in 2006 and 2007, our Energy Services business grew to the point that it represented approximately 81% of 2007 revenue. The balance of our consolidated 2007 revenue was derived from our Energy Technology business. The details of our history follow.
          On December 5, 1997, we were formed as Electric City LLC, a Delaware limited liability company, for the purpose of marketing a line of lighting controllers (which we marketed under the EnergySaver name) the core technology of which was developed in Italy. On June 5, 1998, we changed from a limited liability company into a corporation by merging Electric City LLC into Electric City Corp., a Delaware corporation.
          On June 10, 1998, we issued shares of our common stock representing approximately six (6%) percent of our then issued and outstanding common stock, to the shareholders of Pice Products Corporation, an inactive, unaffiliated company with minimal assets, pursuant to a merger agreement. The purpose of the merger was to substantially increase the number of our shareholders to facilitate the establishment of a public trading market for our common stock. Trading in our common stock commenced on August 14, 1998 on the OTC Bulletin Board.

          On May 3, 2005, we acquired Maximum Performance Group, Inc. (“MPG”), a technology-based provider of energy and asset management products and services. MPG manufactures and markets its eMAC line of controllers for HVAC and lighting applications.
          In June 2006 we established our Energy Services business through the acquisition of Parke P.A.N.D.A. Corporation (“Parke”). Parke is an energy services provider specializing in the design, engineering and installation of energy efficient lighting upgrades for commercial and industrial users. We expanded this business through the acquisition of Kapadia Consulting, Inc. in September 2006. Kapadia is an engineering firm that specializes in energy management consulting and energy efficient lighting upgrades for commercial and industrial users. During 2007 we added to this segment through two small acquisitions and the opening of additional offices.
          In December 2006 we discontinued the active marketing of the EnergySaver due to changes in lighting technology, which in our view limited the future market for the product.
          On September 13, 2006 we changed our name to Lime Energy Co. to reflect our new focus. On September 22, 2006 our stock began trading on the OTC Bulletin Board under the trading symbol “LMEC.”
          On February 25, 2008, our stock began trading on the NASDAQ Capital Market under the trading symbol “LIME.”
Products and Services
Energy Services
          Through our wholly-owned subsidiaries we market, design, engineer and install energy efficient lighting upgrades for commercial and industrial users. As part of our services, we seek to determine the best lighting solutions for our customer, taking into consideration factors such as lighting requirements, building environmental conditions, hours of operation, energy costs, available utility and/or tax incentives, and installation, operating and maintenance costs of various lighting alternatives. We then remove the existing lighting system and replace it with a new lighting system manufactured by third party manufacturers. Our customer typically realize paybacks of 12 to 24 months on their lighting system upgrade as the result of lower energy consumption, reduced maintenance costs, utility rebates and tax incentives. A lighting upgrade will also very often improve the overall quality of lighting in a customer’s facility.
          We also provide energy engineering services to assist customers in improving the energy efficiency of their facilities and to better manage their energy costs. Some of the energy engineering services we offer include:
    building energy audits;
 
    energy management planning;
 
    engineering design review with a view to optimizing energy efficiency and energy rebates;
 
    project management of energy related construction or upgrade projects;
 
    HVAC and boiler system optimization; and
 
    incentive and rebate application processing and procurement.

eMAC & uMAC
          The eMAC system is comprised of a heating, ventilating and air conditioning (“HVAC”) controller with wireless communication capabilities and a central, server-based, Internet-accessible software that monitors and controls the operation of the connected HVAC units. The eMAC system is designed for use in commercial and industrial applications with packaged (primarily rooftop) HVAC equipment of 2 to 40 tons (1 ton = 12,000 Btu/hr cooling capacity) and up to 500,000 Btu/hr of heating capacity.
          The eMAC controller is contained in a small box that is mounted on the exterior of a customer’s HVAC unit. The controller is wired into the HVAC equipment and monitors up to 126 points of the equipment’s operation. In addition, each eMAC contains a Pentech Energy Recovery Controller (“PERC”), our patented third generation microprocessor-based technology.
          PERC was developed by Pentech Solutions, a predecessor company to MPG, and is designed to dynamically match an HVAC system’s output to any given load condition, thereby improving the operating efficiency of the equipment. Since most HVAC systems are designed to maintain comfortable environmental conditions on both the hottest and coldest days likely to be experienced, there exists substantial excess system capacity on most days of the year. Due to this excess capacity, the system quickly satisfies a thermostat’s call for heating or cooling, and in doing so overshoots the thermostat set point and leaves Btu’s of heat or cooling in the heat exchanger, cooling coils and air ducts. The PERC controller acts to correct this by periodically turning off the air conditioner’s compressor and condenser fan while continuing to run the evaporator fan, thereby continuing to deliver cooling to the conditioned space utilizing the energy stored in the cooling coils, heat exchanger and air ducts. In heating applications, PERC periodically closes the gas valve while continuing to operate the indoor air fan, delivering heated air into the space utilizing the heat stored in the heat exchanger and air ducts. At the same time, the PERC controller is monitoring the rate of temperature change in the conditioned space in order to avoid overshooting the desired temperature setting. The PERC technology can deliver energy savings of 15% to 20% for our end user customers.
          The wireless communication capabilities of the eMAC allow us to monitor and remotely manage the operation of a customer’s HVAC equipment. A customer can log on to our eMAC web site and obtain information regarding the operation of its HVAC equipment and change equipment operating parameters, such as hours of operation and temperature. The eMAC will also send alarms to our central server when any of the up to 126 monitored points of operation fall outside predetermined operating ranges. This often permits us to react to a potential equipment problem before the occupants of the space are aware of an equipment malfunction. We charge our customers for this ability to communicate and remotely monitor and mange their equipment, though we often include an initial monitoring period with the purchase of the eMAC so that our customers can become familiar with the benefits of this service.
          The uMAC is a version of the eMAC which has been simplified to remotely control the operation of a facility’s lights via wireless communications. Using the uMAC a customer can remotely, via the Internet, turn lights on and off and change the daily schedule for the operation of a facility’s lighting.
Marketing, Sales and Distribution
          The majority of our sales are derived through the efforts of our internal sales force. We currently have 33 employees whose primary responsibility is sales and marketing working out of ten sales offices, some of which are home offices. Our sales people have been trained to sell all of our products and services, regardless of the subsidiary that employs them or the office that they work out of. Our sales leads are developed from a combination of cold calls, referrals, trade shows and repeat customers.

Customers
          During 2007, one customer, Washington Mutual, Inc. accounted for approximately 10% of our consolidated billings. During 2006, three customers, Kohl’s Department Stores, Modell’s Sporting Goods and Automated Building Controls accounted for 14%, 13% and 13% of our consolidated billings, respectively. During 2005, two customers, Kohl’s Department Stores and Duane Read Inc., accounted for approximately 37% and 11% of our consolidated billings, respectively.
Competition
          There are many competitors in the energy services business, including small regional lighting retrofit companies, electrical contractors and large national energy service companies. The large national energy service companies tend to market to large national companies and compete for large energy retrofit projects in which lighting is one piece of the total project. We focus on providing lighting retrofit services to small to mid-sized commercial and industrial users (which we believe are under-served) and to niche markets, where installations are more difficult. In these markets we market our services based on the financial return to our customers and we differentiate ourselves through our thorough upfront analysis of the application, our experience, our reputation for quality work, our superior service, our ability to provide complete energy engineering services through our engineering group and our ability to provide extended payment terms.
          Energy engineering services such as those provided by our engineering group are also generally widely available. The certifications held by our engineers include: Professional Engineer (“PE”); Certified Energy Engineer (“CEM”); and Certified Lighting Efficiency Professional (“CLEP”). To obtain these certifications an individual must have a high level of experience and demonstrated knowledge of engineering and energy engineering concepts. Kapadia, our energy engineering company, differentiates itself from its competitors through its reputation for quality work and its 27 years of experience as an energy engineering firm. A significant amount of energy engineering business comes from repeat customers or referrals.
          While there are other HVAC controllers that provide energy saving benefits similar to the eMAC, we are not aware of any competing product available at a comparable cost to the eMAC that provides the communications, remote monitoring and diagnostic features of the eMAC. Large, national control companies provide systems that overlap with the capabilities of the eMAC, but the installed cost of such systems make them impractical for smaller applications, which is the market we are targeting with the eMAC.
Manufacturing
          The eMAC is manufactured for us by a contract manufacturer in southern California. We believe that this contract manufacturer has sufficient capacity to handle our anticipated growth in eMAC sales for the foreseeable future. In addition, we believe that there are many contract manufacturers across the country that could manufacture the eMAC for us if for some reason our current contract manufacturer could not meet our needs.
          Most components of the eMAC are sourced from multiple suppliers, though some components are proprietary to a single manufacturer. We periodically engage in discussions with additional parts suppliers, seeking to ensure lowest cost pricing and reliability of supply.
          Our lighting products are purchased from third party suppliers and manufacturers. These products are generally widely available and are selected based on a combination of price, performance, features and availability.

Table of Contents

          During 2007, approximately 27% of our consolidated materials and subcontracted labor came from two suppliers. During 2006 approximately 12% of our consolidated purchases were made from one supplier. During 2005, approximately 20% of our consolidated material purchases were made from four suppliers. Purchases from any one supplier will vary year-to-year depending on sales and inventory levels. None of our largest suppliers sell the Company proprietary products that we could not purchase from other vendors.
Compliance With Environmental Laws
          Neither the production, nor the sale of our products in any material way generates activities or materials that require compliance with federal, state or local environmental laws. Our Energy Services businesses use licensed disposal firms to dispose of old lamps, lighting ballasts or other products that may contain heavy metals or other potential environmental hazards.
Research and Development
          Our engineering staff, in conjunction with outside engineering consultants, based on the day-to-day use of the eMAC and its components and various testing sites around the country, develops modifications and improvements to the product line. Total research and development costs charged to operations were approximately $700,000, $535,000 and $395,000 for the years ended December 31, 2007, 2006 and 2005, respectively.
Intellectual Property
          As of December 31, 2007, we had nine issued patents and two patents pending before the U.S. Patent and Trademark Office, as well as foreign patent offices on various aspects of the eMAC and EnergySaver technologies. In addition we have registered four trademarks and have two additional trademark registrations pending.
Employees
          As of March 15, 2008, we had 110 full time employees and six part time employees, of which 18 were management and corporate staff, 11 were engineers, 33 were engaged in sales and marketing and 48 were engaged in project management, product installation, customer support and field service.
Item 1A. Risk Factors.
          The following disclosure of risk factors includes all material risks known to us at this time. Additional risks we are not presently aware of or that we currently believe are immaterial may prove to impair our business and financial performance. Our business could be harmed by any of these risks, whether stated or unstated. We operate in a continually changing business environment and may as a result enter into new businesses and product lines. We cannot predict new risk factors that may arise in the future, and we cannot assess the impact, if any, of these new risk factors on our businesses or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those projected in any forward-looking statements. Accordingly, you should not rely on forward-looking statements as a prediction of actual results. In addition, our estimates of future operating results are based on our current complement of businesses, which is subject to change as we continue to assess and refine our business strategy. If any of the following risks actually occur, our business, results of operations, and financial condition could be adversely affected in a material manner.

Risks Related to Our Business
We have incurred significant operating losses since inception and may not achieve or sustain profitability in the future.
          We have experienced operating losses and negative cash flow from operations since our inception in December 1997 and we currently have an accumulated deficit. Our ability to continue as a going concern is ultimately dependent on our ability to increase sales to a level that will allow us to operate profitably and sustain positive operating cash flows. Although we are continuing our efforts to improve profitability through expansion of our business in both current and new markets, we must overcome marketing hurdles, including gaining market acceptance, in order to sell large quantities of our products and services. In addition, we may be required to reduce the prices of our products in order to increase sales. If we reduce prices, we may not be able to reduce costs sufficiently to achieve acceptable profit margins. As we strive to grow our business, we have spent and expect to continue to spend significant funds (1) for general corporate purposes, including working capital, marketing, recruiting and hiring additional personnel; and (2) for research and development. To the extent that our revenues do not increase as quickly as these costs and expenditures, our results of operations and liquidity will be materially adversely affected. If we experience slower than anticipated revenue growth or if our operating expenses exceed our expectations, we may not achieve profitability. Even if we achieve profitability in the future, we may not be able to sustain it.
Failure to effectively market our energy management products and services could impair our ability to sell significant quantities of these products and services.
          We operate in competitive markets. One of the challenges we face in commercializing our energy management products and services is demonstrating the advantages of our products and services over competitive products and services. To do this, we will need to further develop our marketing and sales force. If we do not successfully develop and expand our internal sales force, we may not be able to generate significant revenues.
If our products and services do not achieve or sustain market acceptance, our ability to compete will be adversely affected.
          To date, we have not sold our eMAC product line in very large quantities and a sufficient market may not develop for it. Significant marketing will be required in order to establish a sufficient market for these products. The technology underlying our products may not become or remain a preferred technology to address the energy management needs of our customers and potential customers. Failure to successfully develop, manufacture and commercialize products on a timely and cost-effective basis will have a material adverse effect on our ability to compete in the energy management market or survive as a business.
The failure to effectively maintain and upgrade our proprietary products could adversely affect our business.
          A recent effort to upgrade the eMAC technology has taken significantly longer and cost more than initially anticipated. This delay has adversely affected eMAC sales, resulting in significant losses at MPG which contributed to the impairment of its goodwill. The situation has also diverted a significant amount of management’s attention from the operation of our other businesses. While we have taken steps to address the situation, if they prove ineffective we may continue to experience losses and a drain on our management and cash resources. Maintenance of proprietary technology will be an ongoing issue that we must effectively handle without impacting sales and profitability.

Table of Contents

Failure to replace a significant customer could materially and adversely affect our results of operations and financial condition.
          We have historically derived a significant portion of our annual revenue from a limited number of customers. Seldom has any one customer represented 10% or more of our revenues for more than one year in a row. This requires that we continually replace major customers, whose needs we have satisfied, with one or more new customers. The failure to replace a major customer could have a significant negative effect on our results of operations and financial condition. We believe that as a result of recent acquisitions we will experience an increased diversification of our customer base, reducing the amount of our revenue associated with several large customers, but this remains to be seen.
We expect our quarterly revenue and operating results to fluctuate. If we fail to meet the expectations of market analysts or investors, the market price of our common stock could decline substantially, and we could become subject to securities litigation.
          Our business is seasonal and can be affected by cyclical factors outside of our control. Our quarterly revenue and operating results have fluctuated in the past and will likely vary from quarter to quarter in the future. You should not rely upon the results of one quarter as an indication of our future performance. Our revenue and operating results may fall below the expectations of market analysts or investors in some future quarter or quarters. Our failure to meet these expectations could cause the market price of our common stock to decline substantially. If the price of our common stock falls significantly we may be the target of securities litigation. If we become involved in this type of litigation, regardless of the outcome, we could incur substantial legal costs, management’s attention could be diverted from the operation of our business, and our reputation could be damaged, which could adversely affect our business, results of operations and/or financial condition.
A decrease in electric retail rates could lessen demand for our products.
          Our products and services have the greatest sales and profit potential in areas where commercial electric rates are relatively high. However, retail electric rates for commercial establishments in the United States may not remain at their current levels. Due to a potential overbuilding of power generating stations in certain regions of the United States, wholesale power prices may decrease in the future. Because the price of commercial retail electric power is largely attributed to the wholesale cost of power, it is reasonable to expect that commercial retail rates may decrease as well. In addition, much of the wholesale cost of power is directly related to the price of certain fuels, such as natural gas, oil and coal. If the prices of those fuels decrease, the prices of the wholesale cost of power may also decrease. This could result in lower electric retail rates and reduced demand for our energy saving products and services.
If we are not able to protect our intellectual property rights against infringement, or if others obtain intellectual property rights relating to energy management technology, we could lose our competitive advantage in the energy management market.
          We regard our intellectual property rights, such as patents, licenses of patents, trademarks, copyrights and trade secrets, as somewhat important to our success. Although we have entered into confidentiality and rights to inventions agreements with our employees and consultants, the steps we have taken to protect our intellectual property rights may not be adequate. Third parties may infringe or misappropriate our intellectual property rights or we may not be able to detect unauthorized use and take appropriate steps to enforce our rights. Failure to take appropriate protective steps could materially adversely affect any competitive advantage we may have in the energy management market. In addition, patents held by third parties may limit our ability to manufacture, sell or otherwise commercialize products and could result in the assertion of claims of patent infringement against us. If that were to

Table of Contents

happen, we could try to modify our products to be non-infringing, but we might not be successful or such modifications might not avoid infringing on the intellectual property rights of third parties.
          Claims of patent infringement against us, regardless of merit, could result in the expenditure of significant financial and managerial resources by us. We could be forced to seek to enter into license agreements with third parties to resolve claims of infringement by our products of the intellectual property rights of third parties. Such licenses may not be available on acceptable terms or at all. The failure to obtain such licenses on acceptable terms could have a negative effect on our business.
If we are unable to achieve or manage our growth, it will adversely affect our business, the quality of our products and services, and our ability to attract and retain key personnel.
          If we succeed in growing our sales as we need to do, we will be subject to the risks inherent in the expansion and growth of a business enterprise. Growth in our business will place a strain on our operational and administrative resources and increase the level of responsibility for our existing and new management personnel. To manage our growth effectively, we will need to:
    further develop and improve our operating, information, accounting, financial and other internal systems and controls on a timely basis;
 
    improve our business development, marketing and sales capabilities; and
 
    expand, train, motivate and manage our employee base.
          Our systems currently in place may not be adequate if we grow and may need to be modified and enhanced. The skills of management currently in place may not be adequate if we experience significant growth.
If our management fails to properly identify companies to acquire and to effectively negotiate the terms of these acquisition transactions, our growth may be impaired.
          As part of our growth strategy, we intend to seek to acquire companies with complementary technologies, products and/or services. Our management, including our board of directors, will have discretion in identifying and selecting companies to be acquired by us and in structuring and negotiating these acquisitions. In general, our common stockholders may not have the opportunity to approve these acquisitions. In addition, in making acquisition decisions, we will rely, in part, on financial projections developed by our management and the management of potential target companies. These projections will be based on assumptions and subjective judgments. The actual operating results of any acquired company or the combination of us and an acquired company may fall significantly short of projections.
          We may be unable to acquire companies that we identify as targets for various reasons, including:
    our inability to interest such companies in a proposed transaction;
 
    our inability to agree on the terms of an acquisition;
 
    incompatibility between our management and management of a target company; and
 
    our inability to obtain the approval of the holders of our common stock, if required.
          If we cannot consummate acquisitions on a timely basis or agree on terms at all, or if we cannot acquire companies with complementary technologies, products and/or services on terms acceptable to us, our future growth may be impaired.

Table of Contents

Our growth may be impaired and our current business may suffer if we do not successfully address risks associated with acquisitions.
          Since January 1, 2000, we have acquired seven companies, two of which we subsequently sold at a loss and one of which performed below expectation necessitating a write-off of the associated goodwill. Our future growth may depend, in part, upon our ability to successfully identify, acquire and operate other complementary businesses. We may encounter problems associated with such acquisitions, including the following:
    difficulties in integrating acquired operations and products with our existing operations and products;
 
    difficulties in meeting operating expectations for acquired businesses;
 
    diversion of management’s attention from other business concerns;
 
    adverse impact on earnings of amortization or write-offs of goodwill and other intangible assets relating to acquisitions; and
 
    issuances of equity securities that may be dilutive to existing stockholders to pay for acquisitions.
          In addition, often an acquired company’s performance is largely dependent on a few key people, particularly in smaller companies. If these key people leave the company, become less focused on the business or less motivated to make the business successful after the acquisition, the performance of the acquired company may suffer.
If sufficient additional funding is not available to us, the commercialization of our products and services and our ability to grow is likely to be hindered.
          Our operations have not generated positive cash flow since the inception of the Company in 1997. We have funded our operations through the issuance of common and preferred stock and secured debt. Our ability to continue to operate until our cash flow turns positive may depend on our ability to continue to raise funds through the issuance of equity or debt. If we are not successful in raising additional funds, we might have to significantly scale back or delay our growth plans, sell or shut down some of our businesses or possibly cease operations altogether. Any reduction or delay in our growth plans could materially adversely affect our ability to compete in the marketplace, take advantage of business opportunities and develop or enhance our products and services. If we should have to cease operations altogether, our stockholders’ investment is likely to be lost.
Raising additional capital or consummation of additional acquisitions through the issuance of equity or equity-linked securities could dilute your ownership interest in us.
          We may find it necessary to raise capital again some time in the future. If we raise additional funds in the future through the issuance of equity securities or convertible debt securities, our existing stockholders will likely experience dilution of their present equity ownership position and voting rights. Depending on the number of shares issued and the terms and conditions of the issuance, new equity securities could have rights, preferences, or privileges senior to those of our common stock. Depending on the terms, common stock holders may not have approval rights with respect to such issuances.

Item 2. Properties.
          Our headquarters are located at 1280 Landmeier Road in Elk Grove Village, Illinois. This facility is approximately 13,000 square feet and houses the corporate headquarters and a warehouse.

          We believe that the space and location of our current facilities in combination with the current and planned outsourcing of our manufacturing will be sufficient to reach a level of sales and production projected for the current year.
Item 3. Legal Proceedings.
          From time to time, the Company has been a party to pending or threatened legal proceedings and arbitrations that are routine and incidental to its business. Based upon information presently available, and in light of legal and other defenses available to the Company, management does not consider the liability from any threatened or pending litigation to be material to the Company.
Item 4. Submission of Matters to a Vote of Security Holders.
          On November 13, 2007, we received a written consent in lieu of a meeting of Stockholders from the holders of shares representing 67.1% of the total issued and outstanding shares of our common stock authorizing our Board of Directors, in its discretion, to effect a reverse stock split at an exchange ratio ranging from one-for-two to one-for-ten of our issued and outstanding shares of common stock. We sought approval to effect this reverse split for the purpose of qualifying for listing of our common stock on the NASDAQ Capital Market.
          On November 29, 2007, we distributed an information statement to all stockholders of record as of November 26, 2007, informing them of this written consent in lieu of a meeting.
          On January 16, 2008, our Board of Directors authorized a 1 for 7 reverse split of our stock, effective at the opening of business on January 28, 2008. All share figures in this annual report reflect this reverse stock split.

Recent Sales of Unregistered Securities
          During the twelve months ended December 31, 2007, we issued the securities listed below:
    In January 2007, pursuant to the Directors’ Stock Option Plan we granted options to certain outside directors with an exercise price of $6.30 per share, which was the market price on the date of issuance. Warrants held by 12 investors, including Messrs. Asplund and Kiphart, contained anti-dilution provisions that automatically adjust the exercise price on the warrants to the issuance price of any security convertible into our common stock if the price of the newly issued security is less than the exercise price on the holder’s warrant. Prior to the granting of the directors’ options in January 2007, the exercise price on these warrants was $7.00 per share. The grant of the director options caused the exercise price on these warrants to automatically be reduced to $6.30 per share.
 
    During January 2007, we issued warrants to consultants with terms of two to three years to purchase 38,571 shares of our common stock at prices of $7.00 to $7.56 per share as partial consideration for services provided to us.
 
    A provision of our June 2006 PIPE transaction required us to file and have declared effective by no later than November 3, 2006, a registration statement registering the shares issued as part of the transaction. To the extent that we failed to have the registration statement declared effective by this date, we were required to pay penalties to the PIPE investors at the rate of 1% per month of the purchase price paid by the investors. Largely as a result of the questions regarding the need to amend our Certificate of Incorporation to effect the 2006 reverse split of our common stock, we were not able to have the registration statement declared effective until February 14,

      2007. All of the investors in the PIPE transaction agreed to accept shares of our common stock as payment of this registration penalty. As of December 31, 2006, we had accrued $345,583 in penalties related to our failure to register these shares. These accrued penalties, along with $268,125 of penalties for the period from January 1, 2007 through February 14, 2007, were satisfied through the issuance of 87,673 shares of our common stock in January and February 2007.
 
    On February 23, 2007, we commenced a rights offering to stockholders in which we distributed to each holder of record as of February 23, 2007 (other than the former Series E Preferred stockholders and Daniel Parke, who waived their rights to participate), non-transferable subscription rights to purchase shares of our common stock at $7.00 per share. Stockholders that participated in the rights offering were also able to subscribe for any shares that were not purchased by other stockholders pursuant to their subscription rights. The rights offering closed on March 30, 2007 and raised $2,796,700 (net of issuance costs of $202,932) through the issuance of 428,519 shares of common stock to 260 of our existing stockholders. We received the proceeds from the offering and issued the common stock to the participants during the first week of April 2007.
 
    In connection with the placement of the subordinated convertible term notes during the second quarter of 2007 we issued four-year warrants to eight investors, including Richard Kiphart, our chairman and largest individual stockholder, to purchase 206,043 shares of our common stock at $7.28 per share.
 
    As part of the MPG acquisition, 23,735 shares of common stock were deposited in escrow for the benefit of the selling stockholders of MPG to be released over the two-year period following the April 30, 2005 purchase of MPG if it achieved certain revenue targets during the period. During May 2007 we issued 2,818 shares to the former MPG stockholders which we determined we owed them pursuant to the MPG merger agreement.
 
    Delano Group Securities LLC acted as an advisor on the acquisition of MPG in 2005. Part of Delano’s compensation for its services was tied to the purchase price paid for MPG. David Asplund owned and operated Delano prior to joining Lime Energy as our CEO in January 2006. Since the release of the escrow shares was considered a payment of additional consideration to the former stockholders of MPG, we issued Mr. Asplund 141 shares of our common stock in May 2007 in satisfaction of the commission owed Delano.
 
    On June 6, 2007, retroactive to May 31, 2007, we acquired the assets and assumed certain liabilities of George Bradley Boyett dba Texas Energy Products. The purchase consideration consisted of 28,571 shares of our common stock and cash of $312,787.
 
    On August 6, 2007, retroactive to July 31, 2007, we acquired the assets and assumed certain liabilities of Preferred Lighting, Inc. for 15,069 shares of our common stock and cash of $409,953 in cash (including $109,953 paid in 2008 pursuant to an earn-out based on 2007 earnings). We also issued five year warrants to the former owners of Preferred Lighting to purchase 21,429 shares of our common stock at $13.23 per share.
 
    During 2007, we issued 7,088 shares of our common stock to the holders of our subordinated convertible term notes in satisfaction of 50% of the interest owed on the notes.
 
    During 2007 certain employees and a former director exercised options to purchase 33,005 shares of our common stock at prices ranging from $6.30 to $7.14 per share.

Table of Contents

    During 2007 six investors exercised their warrants to purchase 5,011 shares of our common stock at $6.30 per share. One of these investors elected to exercise its warrant on a cashless basis, surrendering 569 shares it would have otherwise be entitled to receive on exercise to cover the exercise price.
The sales and issuances of common stock, debt instruments and warrants to purchase common stock in private placements listed above were made by us in reliance upon the exemptions from registration provided under Sections 4(2) and 4(6) of the Securities Act of 1933, as amended, and Rule 506 of Regulation D, promulgated by the SEC under federal securities laws and comparable exemptions for sales to “accredited” investors under state securities laws. The offers and sales were made to accredited investors as defined in Rule 501(a) under the Securities Act and no general solicitation was made by us or any person acting on our behalf; the securities sold were subject to transfer restrictions, and the certificates for those shares contained an appropriate legend stating that they had not been registered under the Securities Act and may not be offered or sold absent registration unless sale is pursuant to an exemption therefrom.

Item 7.   Management’s Discussion and Analysis of Financial Condition and Results of Operations.
          The following discussion should be read in conjunction with the consolidated financial statements and related notes which appear elsewhere in this report on Form 10-K. The discussion contains “forward-looking statements” within the meaning of the Private Securities Litigation Act of 1995. Such statements consist of any statement other than a recitation of historical fact and can be identified by the use of forward-looking terminology such as “may,” “expect,” “anticipate,” “estimate” or “continue” or the negative of such terms or other variations of such terms or comparable terminology. You are cautioned that all forward-looking statements are necessarily speculative and there are certain risks and uncertainties that could cause actual events or results to differ materially from those referred to in such forward-looking statements. We do not have a policy of updating or revising forward-looking statements and, therefore, you should not assume that our silence over time means that actual events are bearing out as estimated in such forward-looking statements.
Overview
          We are a provider of energy services and technologies that improve the energy efficiency of our clients’ facilities and reduce their ongoing maintenance costs. Services we offer include the design, engineering and installation of energy efficient lighting systems and energy engineering consulting. We also market a proprietary line of controllers that provide intelligent control and continuous monitoring of HVAC and lighting equipment via wireless communication technology to reduce energy usage and improve system reliability.
          The Company consists of three reporting segments: Energy Services, Energy Technology and Financial Services.
          Our Energy Services segment markets, designs, engineers and installs energy efficient lighting upgrades for commercial and industrial users. As part of our services, we seek to determine the best lighting solutions for our customers, taking into consideration factors such as lighting requirements, building environmental conditions, hours of operation, energy costs, available utility and/or tax incentives, and installation, operating and maintenance costs of various lighting alternatives.
          Our Energy Technology segment sells our proprietary line of HVAC controllers to commercial and industrial users under the eMAC brand name. The eMAC, which we added through the acquisition of Maximum Performance Group, Inc. in May 2005, provides remote monitoring and control, and reduces the energy consumed by commercial rooftop HVAC units. Prior to 2007 we also actively marketed the EnergySaver line of lighting controllers to commercial and industrial customers. The EnergySaver reduced the energy consumed by ballasted commercial lighting fixtures. We discontinued the active marketing of the EnergySaver in December 2006 due to changes in lighting technology which we felt would reduce the future market for the product.
          Our Financial Services segment was created in 2007 to provide liquidity to our operating subsidiaries by purchasing certain long term receivables from them. The ability to offer extended payment terms to our customers can be an important differentiating factor in certain markets and with certain types of customers. By consolidating all of these long term receivables under Lime Finance, we hope to better manage them and eventually leverage them with debt financing to reduce the cost of capital used to fund them. As of December 31, 2007 we had approximately $400,000 of receivables in this portfolio.
          Our Company has evolved considerably since it was formed in 1997 as an energy technology company to manufacture and sell the EnergySaver. The eMAC line of HVAC and lighting controllers has

16


Table of Contents

replaced the EnergySaver as our energy technology product, and energy technology is no longer our primary source of revenue. Our Energy Services segment, which was formed in June 2006, has grown rapidly through acquisitions and organic growth, such that it represented 81% of our consolidated revenue in 2007. The growth of this segment is expected to continue to outpace that of our Energy Technology segment such that it will be the primary contributor to our growth in 2008.
Critical Accounting Policies and Estimates
          The discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amount of assets and liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities at the date of our financial statements. Actual results may differ from these estimates under different assumptions or conditions. Critical accounting policies are defined as those that are reflective of significant judgments and uncertainties, and potentially result in materially different results under different assumptions and conditions. We believe that our critical accounting policies are limited to those described below. For a detailed discussion on the application of these and other accounting policies, see Note 3 in the notes to the consolidated financial statements.
          Use of Estimates
          Preparation of the consolidated financial statements in accordance with accounting principles generally accepted in the United States requires management to make estimates and assumptions affecting the reported amounts of assets, liabilities, revenues and expenses and related contingent liabilities. On an on-going basis, the Company evaluates its estimates, including those related to revenues, bad debts, warranty accrual, income taxes and contingencies and litigation. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or conditions.
          Revenue Recognition
          We recognize revenue when all four of the following criteria are met: (i) persuasive evidence has been received that an arrangement exists; (ii) delivery of the products and/or services has occurred; (iii) the selling price is fixed or determinable; and (iv) collectibility is reasonably assured. In addition, we follow the provisions of the Securities and Exchange Commission’s Staff Accounting Bulletin No. 104, Revenue Recognition, which sets forth guidelines in the timing of revenue recognition based upon factors such as passage of title, installation, payments and customer acceptance. Any amounts received prior to satisfying our revenue recognition criteria is recorded as deferred revenue.
          Our MPG subsidiary often bundles contracts to provide monitoring services and web access with the sale of its eMAC hardware. As a result, these sales are considered to be contracts with multiple deliverables which at the time the hardware is delivered and installed includes undelivered services essential to the functionality of the product. Accordingly, we defer the revenue for the product and services and the cost of the equipment and installation and recognize them over the term of the monitoring contract. The monitoring contracts vary in length from one month to five years.
          Profit Recognition on Long-Term Contracts
          We account for revenue on most of our long-term contracts on the completed contract method, whereby revenue is recognized once the project is substantially complete. However, we account for revenues on some long-term contracts under the percentage of completion method in conjunction with the

17


Table of Contents

cost-to-cost method of measuring the extent of progress toward completion. Any anticipated losses on contracts are charged to operations as soon as they are determinable.
          Allowance for Doubtful Accounts
          We maintain an allowance for doubtful accounts for estimated losses resulting from the inability of our customers to make required payments. The allowance is largely based upon specific knowledge of customers from whom collection is determined to be doubtful and our historical collection experience with such customers. If the financial condition of our customers or the economic environment in which they operate were to deteriorate, resulting in an inability to make payments, or if our estimates of certain customers’ ability to pay are incorrect, additional allowances may be required. During 2007, we increased our allowance by $126,000 and wrote off receivables of $341,000. As of December 31, 2007 our allowance for doubtful accounts was approximately $151,000, or 2.4% of our outstanding accounts receivable.
          Impairment of Long-Lived Assets.
          We record impairment losses on long-lived assets used in operations when events and circumstances indicate that the assets might be impaired and the undiscounted cash flows estimated to be generated by those assets are less than the carrying amount of those items. Our cash flow estimates are based on historical results adjusted to reflect our best estimate of future market and operating conditions. The net carrying value of assets not recoverable is reduced to fair value. Our estimates of fair value represent our best estimate based on industry trends and reference to market rates and transactions.
          During 2006, we determined that our EnergySaver based VNPP (“Virtual Negawatt Power Plan”) Asset was completely impaired and recorded an impairment charge of $1,183,525 to reduce the carrying value of the asset to zero.
          Goodwill
          We have made acquisitions in the past that included a significant amount of goodwill and other intangible assets. Goodwill is subject to an annual (or under certain circumstances more frequent) impairment test based on its estimated fair value. Estimated fair value is less than value based on undiscounted operating earnings because fair value estimates include a discount factor in valuing future cash flows. There are many assumptions and estimates underlying the determination of an impairment loss, including economic and competitive conditions, operating costs and efficiencies. Another estimate using different, but still reasonable, assumptions could produce a significantly different result. In February 2006 we signed a non-binding letter of intent to sell Great Lakes Controlled Energy. To indicate if our goodwill would be impaired as a result of the expected sale, we compared the carrying value of the related reporting unit to the expected sale price of the business and determined that the goodwill was impaired. As a result we recorded an impairment loss as of December 31, 2005 of $242,830.
          During the fourth quarter of 2007 we updated our projections for portions of the Energy Services and Energy Technology businesses and estimated the fair value based on the discounted current value of the estimated future cash flows. We then compared the calculated fair values of the reporting units to their carrying values. The analysis did not identify any impairment for the Energy Services business, but did determine that the value of the Energy Technology’s goodwill was impaired. The decline in the fair value of the Energy Technology segment was primarily the result of lower than expected sales of the eMAC line of HVAC controllers, in large part due to delays in a project to upgrade the eMAC. As a result of the decline in the fair value, we recorded an impairment loss of $4,181,969 during the fourth quarter of 2007.

18

          It is possible that upon completion of future impairment tests, as the result of changes in facts or circumstances, we may have to take additional charges in future periods to recognize a further write-down of the value of the goodwill attributed to our acquisitions to their estimated fair values.
          Stock-based Compensation
          We have a stock incentive plan that provides for stock-based employee compensation, including the granting of stock options and shares of restricted stock, to certain key employees. The plan is more fully described in Note 25 to our financial statements. Effective January 1, 2006, we adopted Statement of Financial Accounting Standards No. 123(R), “Share-based Payment” (“SFAS 123(R)”), which requires that we record stock compensation expense for equity-based awards granted, including stock options and restricted stock unit grants, over the service period of the equity-based award based on the fair value of the award at the date of grant. Prior to the adoption of SFAS 123(R), we accounted for stock compensation using the recognition and measurement principles of Accounting Principles Board Opinion No. 25, “Accounting for Stock Issued to Employees,” and related Interpretations. Under that method, compensation expense was recorded only if the current market price of the underlying stock on the date of grant exceeded the option exercise price. Since stock options are granted at exercise prices that are greater than or equal the market value of the underlying common stock on the date of grant under our stock incentive plan, no compensation expense related to stock options was recorded in the Consolidated Statements of Operations prior to January 1, 2006. We recognized $3,726,731 and $4,828,955 of stock compensation expense during 2007 and 2006, respectively.
Material Trends and Uncertainties
          From time to time changes occur in our industry or our business that make it reasonably likely that aspects of our future operating results will be materially different than historical operating results. Sometimes these matters have not occurred, but their existence is sufficient to raise doubt regarding the likelihood that historical operating results are an accurate gauge of future performance. We attempt to identify and describe these trends, events, and uncertainties to assist investors in assessing the likely future performance of the Company. Investors should understand that these matters typically are new, sometimes unforeseen, and often are fluid in nature. Moreover, the matters described below are not the only issues that can result in variances between past and future performance nor are they necessarily the only material trends, events, and uncertainties that will affect the Company. As a result, investors are encouraged to use this and other information to judge for themselves the likelihood that past performance will be indicative of future performance.
          The trends, events, and uncertainties set out in the remainder of this section have been identified as those we believe are reasonably likely to materially affect the comparison of historical operating results reported herein to either other past period results or to future operating results. These trends, events and uncertainties include:
          Recent changes in the composition of our company. In 2006 we established our energy services business through the acquisitions of Parke and Kapadia. Additional acquisitions and the opening of new offices have added to this business such that our Energy Services business generated approximately 81% of our consolidated revenue in 2007. Certain characteristics of this new business, such as seasonality, margins and working capital requirements, are fundamentally different that those of our previous business, therefore, we believe our historical results will not be indicative of our future performance. As an example, the Energy Services business appears to be somewhat seasonal with the strongest sales occurring in the second half of the year. This seasonality is likely to result in greater fluctuations in our revenue, earnings and working capital requirements throughout the year than we have historically

experienced. Because certain of our expenses are relatively fixed as described below, seasonal fluctuations in the revenues of our energy services business are also likely to cause fluctuations in our gross margins during the year.
          Uncertainty regarding our Energy Technology Segment. The Company was founded in 1997 for the purpose of marketing the EnergySaver line of energy efficient lighting controllers. In December 2006, due to changes in lighting technology, we discontinued the active marketing of the EnergySaver product and wrote off most of our remaining inventory and our investment in the Virtual Negawatt Power Plan. In May 2005, we added the eMAC and uMAC line of HVAC and lighting controllers (the “eMAC line”) through the acquisition of Maximum Performance Group, Inc. To date, neither product line has reached the level of sales necessary to contribute to our profitability.
          In late 2006, we commissioned an independent review of the market for the eMAC which concluded that there appears to be a good market for the product. We therefore began an engineering project to replace certain components that were being discontinued by their manufacturers, to add cellular communications capabilities and to enable LEED certification and UL listing approval. The project has experienced delays and cost overruns and, due to the limited availability of certain discontinued components for the existing version of the eMAC line, resulted in lower than expected sales of the eMAC during 2007. The Energy Technology segment incurred a significant loss during 2007, in part due to the fact that the sales and administrative overhead of this segment was positioned to support a higher level of eMAC sales than was actually achieved during the year. These events contributed to the determination that MPG’s goodwill was impaired, resulting in the $4,181,969 impairment charge at the end of 2007.
          We have retained an engineering consulting firm to assume responsibility for completing the eMAC upgrades with the objective of completing an upgraded version of the product in the second half of 2008. We have also reduced the overhead of this segment in an attempt to reduce its 2008 loss. While we continue to believe there is a good market for the eMAC product line, we have not determined whether we can achieve the scale necessary for it to become a profitable business. The successful completion of the eMAC engineering project during 2008 will be key to determining the future of this business. We are committed to turning around the performance of this segment and are carefully reviewing all of our alternatives for this business.
Results of Operations
          Our revenue reflects the sale of our products and services, net of allowances for returns and other adjustments. Our revenue is generated from the sale of services and products, primarily in the U.S. Nine customers collectively accounted for approximately 50% of our consolidated billings during 2007, while three customers collectively accounted for approximately 40% of our consolidated billings during 2006.
          The cost of goods sold for our Energy Services business consists primarily of materials, our internal labor and the cost of subcontracted labor. The costs of goods sold for our Energy Technology business include charges from the contract manufacturer that manufactures the eMAC line of controllers, charges from outside contractors used to install our product in our customers’ facilities, depreciation, freight and charges for potential future warranty claims.
          Sales and gross profits depend in part on the volume and mix of products and services sold during any given period. A portion of our expenses, such as the cost of certain supervisory personnel, are relatively fixed. Accordingly, an increase in the volume of sales will generally result in an increase to our margins since these fixed expenses do not increase proportionately with sales.

          Selling, general and administrative (“SG&A”) expenses include the following components:
    direct labor and commission costs related to our employee sales force;
 
    expenses related to our non-manufacturing management, supervisory and staff salaries and employee benefits, including the costs of share based compensation;
 
    commission costs related to our independent sales representatives and our distributors;
 
    costs related to insurance, travel and entertainment and office supplies and the cost of non-manufacturing utilities;
 
    costs related to marketing and advertising our products;
 
    legal and accounting expenses;
 
    research and development expenses; and
 
    costs related to administrative functions that serve to support the existing businesses of the Company, as well as to provide the infrastructure for future growth.
          Interest expense includes the costs and expenses associated with the mortgage on our headquarters building, the subordinated convertible term notes (including amortization of the related debt discount and issuance costs) and various vehicle loans, all as reflected on our current and prior financial statements. Also included in interest expense for 2006 are the costs and expenses associated with working capital indebtedness and two convertible term loans (including amortization of the related debt discount and deferred financing costs). The working capital line and convertible term loans were retired in full in June 2006.
Twelve-Month Period Ended December 31, 2007 Compared With the Twelve-Month Period Ended December 31, 2006
          Revenue. Our revenue increased $11,337,506, or 139%, to $19,481,130 during the year ended December 31, 2007, as compared to $8,143,624 for the year ended December 31, 2006. Of our 2007 revenue approximately 81% was derived from our Energy Services business and 19% was derived from our Energy Technology business. During 2006 Energy Services and Energy Technology generated 41% and 59% of our total revenue, respectively.
          Revenue for our Energy Services segment was $16,182,172 during 2007, an increase of $12,880,158, or 390% over the $3,302,014 recognized in 2006. Contributing to the increase in revenue for the Energy Services segment was inclusion of Parke and Kapadia for a full year in 2007 (both were acquired during 2006), and the acquisitions of Texas Energy and Preferred Lighting during 2007. Revenue also benefited from an increase in the number of salespeople working in the segment and increased experience of our salespeople. Revenue for the Energy Services segment is expected to continue to grow as the salespeople added and the acquisitions made in 2007 contribute for a full year.
          Revenue for the Energy Technology segment was $3,609,816 in 2007, a decline of $1,231,794 or 25%, from the $4,841,610 recorded in 2006. The decline in revenue was the result of our decision in December 2006 to discontinue the active marketing of the EnergySaver. Our eMAC related revenue was approximately flat in 2007 when compared to 2006. While the segment benefited from utility energy rebates for certain eMAC projects, eMAC sales declined approximately 25% due to limited availability of product resulting from delays in the development of a new version of the eMAC. We hope that the new version of the eMAC will be ready for distribution in the second half of 2008, in the meantime availability of the product will continue to be limited. As a result, we expect the 2008 revenue for the Energy Technology segment to be lower than the level achieved in 2007.

Table of Contents

          During 2007 we recorded intercompany sales of $319,150 which represented sales from our Energy Technology segment to the Energy Services segment which resold the product to its customer.
          The seasonality of revenue during 2008 is expected to be similar to that of 2007, with significantly higher revenue realized in the third and fourth quarters of the year compared to the first and second quarters.
          Gross Profit. Our gross profit for 2007 was $4,398,730, an increase of $3,186,400, or 263%, from the gross profit of $1,212,330 earned in 2006. Our gross profit margin was 22.6% in 2007, compared to 14.9% in 2006. The improvement in our gross profit was the result of increased revenue in our Energy Services segment. We believe that certain fixed costs contained in our cost of sales will not increase at the same rate as future revenue, which will contribute to increases in our gross margins in future periods. These same fixed costs will also cause fluctuations in our margins on a quarterly basis due to the seasonality of our sales.
          SG&A Expense. Our selling, general and administrative expense increased $906,681, or approximately 7%, to $13,072,381 in 2007 when compared to $12,165,700 in 2006. All of this increase was attributable to the inclusion of a full year of expenses for Parke and Kapadia (both of which were both acquired in 2006) and the additions of Texas Energy and Preferred Lighting during 2007. Our SG&A expense did not grow as fast as our revenue during 2007. As a result, SG&A expense as a percentage of our total revenue declined to 67% in 2007 from 149% in 2006. SG&A expense is expected to increase moderately in 2008 due to the inclusion of a full year of expense for our 2007 acquisitions and new hires, but is expected to continue to decline as a percentage of our total consolidated revenue.
          Amortization of Intangibles. Expense associated with the amortization of intangible assets increased $801,872, or 66%, to $2,011,878 in 2007, from $1,210,006 in 2006. This increase was primarily due to the increase in intangible assets added with the acquisitions of Texas Energy and Preferred Lighting during 2007. Absent any further acquisitions, amortization expense will decline to approximately $858,000 in 2008.
          Impairment Loss. During the fourth quarter of 2007, we completed an impairment analysis of our subsidiary, Maximum Performance Group Inc., and determined that its carrying value exceeded its fair value to the degree that the goodwill associated with this business was completely impaired. As a result we recorded an impairment charge of $4,181,969 in December 2007 to reduce the carrying value of the asset to zero.. The decline in the fair value at Maximum Performance Group was largely due to delays in an engineering project to upgrade the eMAC. Delays in completing this project adversely impacted the sales of the product during 2007, due to limited availability of components, and set back our marketing plans for the product.

          Other Non-Operating Income (Expense). Other expense declined $2,393,958 during 2007 to $685,230, compared to $3,079,188 for 2006. Interest expense declined $2,321,277 to $952,093 in 2007 from $3,273,370 in 2006. The components of interest expense for the years ended December 31, 2007 and 2006 are as follows:

Termination of post re-payment interest obligation
          266,225  
 
Total Interest Expense
  $ 952,093     $ 3,273,370  
 
          Total contractual interest expense (the interest on outstanding loan balances) declined $4,602 in 2007 to $359,637, as compared to $364,239 in 2006. In June 2006 we repaid two convertible terms loans and our convertible revolving note was converted to common stock, which contributed to the decline in contractual interest expense. This was largely offset by new $5 million subordinated convertible term notes which we issued in June 2007.
          Upon the repayment of the convertible term loans in June 2006, we were required to pay a prepayment penalty of $516,071 and to recognize as interest expense the remaining unamortized balance of the capitalized issuance costs and the debt discount totaling $978,525. During June 2006 we also incurred a charge of $266,225 related to the termination of our obligation to pay the term loan lender a portion of certain cash flows for a five-year period. Upon the closing of a PIPE transaction in June 2006 and the repayment of the term loans, the holder of a convertible revolving note elected to convert the outstanding balance on the note into shares of our common stock. The revolving note contained anti-dilution provisions which automatically adjusted the conversion price of the note to $7.00 per share, which is the price at which we issued shares as part of the June 2006 PIPE transaction. The lender would have received 5,557 shares of common stock upon conversion of the revolving note utilizing the conversion price prior to this adjustment, but as a result of the adjustment it received 134,779 shares. The market value of the 126,222 additional shares it received as a result of the adjustment was recorded as interest expense in the amount of $950,865.

Twelve-Month Period Ended December 31, 2006 Compared With the Twelve-Month Period Ended December 31, 2005
          Revenue. Our revenue increased $4,450,195, or 120% to $8,143,624 during the year ended December 31, 2006, as compared to $3,693,429 for the year ended December 31, 2005. Revenue generated by our Energy Services segment was responsible for $3,302,014 or 74% of the increase in our revenue for 2006. The Energy Services segment was created in 2006 through the acquisitions of Parke and Kapadia. During 2006 59% of our revenue was generated by the Energy Technology segment and 41% was generated by our Energy Services segment, while in 2005 100% of our revenue came from the Energy Technology segment.
          The balance of the increase in revenue was generated by our Energy Technology segment due to increased eMAC sales, which was partially offset by lower EnergySaver sales. The increase in the eMAC revenue was due to the inclusion of a full year of results for MPG (MPG was acquired in May 2005) and higher unit sales.
          Gross Profit. Our gross profit increased $1,210,755 to $1,212,330 for the year ended December 31, 2006, as compared to $1,575 for the year ended December 31, 2005, while our gross profit margin increased to 14.9% for 2006 as compared to 0.04% earned in 2005. Included in the 2006 cost of sales was a $568,577 one time charge to write-off most of our EnergySaver inventory due to our decision to terminate the active marketing of this product. Adjusting for this charge, our gross profit for 2006 was $1,780,907, or 21.9% of sales. The increase in gross profit from 2005 was primarily attributable to increased sales of the eMAC and the acquisition of Parke on June 29, 2006. The 2006 cost of goods sold includes $296,953 of share based compensation expense resulting from our adoption of SFAS 123(R) on January 1, 2006. No share based compensation was included in the 2005 cost of goods sold.
          SG&A Expense. Our selling, general and administrative expense increased $6,802,197 or 127% to $12,165,700 for 2006, as compared to $5,363,503 for 2005. Approximately 67% or $4,532,001 of the increase in the 2006 SG&A was related to our adoption of SFAS 123(R) on January 1, 2006. We did not record stock compensation expense in 2005. Other significant items contributing to the increase in SG&A expense was $531,000 in penalties resulting from our inability to have the Laurus registration and the June PIPE registration declared effective within the timeframes required under the related documents, approximately $660,000 of SG&A expense resulting from the inclusion of Parke and Kapadia for portions of 2006 and approximately $680,000 from the inclusion of MPG for the full year.
          Amortization of Intangibles. Intangible Amortization expense increased $738,241 to $1,210,006 in 2006 from $471,765 in 2005. The increase in amortization expense was due to the acquisitions of Parke and Kapadia in 2006.
          Impairment Loss. During the quarter ended September 30, 2006, we completed a preliminary impairment analysis and determined that the carrying value of our VNPP (“Virtual Negawatt Power Plan”) asset exceeded its fair value by $760,488. In order to reduce the carrying value to the fair value we recorded a non-cash impairment charge of $760,488 in September 2006. During the fourth quarter of 2006 we updated our analysis based on new information and revised assumptions and determined that the asset was completely impaired. As a result we reduced the carrying value of the asset to $0 and recorded an additional impairment charge of $423,037 in December 2006. During 2005 recorded an impairment loss of $242,830 related to the reduction in carrying value of goodwill associated with Great Lakes Controlled Energy due to our decision to sell the company.

          Other Non-Operating Income (Expense). Other Expense increased $2,534,935 during 2006 to $3,079,188, compared to $544,253. Interest expense increased $2,670,380 to $3,273,370 during 2006 from $602,990 during 2005. The components of interest expense for the years ended December 31, 2006 and 2005 are as follows:

          Contractual interest expense (the interest on outstanding loan balances) increased $86,662 or 31% to $364,239 during 2006 from $277,577 in 2005. The increase in contractual interest was the result of higher average outstanding balances, due in part to the issuance of the $5 million term loan in November 2005 (which was repaid in June 2006), and higher average interest rates. Amortization of the deferred issuance costs and the debt discount related to the Laurus revolver and convertible term loans, which is included in interest expense, increased $1,010,557 to $1,175,970 during 2006 from $165,413 during 2005. With the early repayment of all of the Laurus loans in June 2006, we were required to recognize as interest expense the remaining unamortized balances of the capitalized issuance costs and the debt discount of $1,009,277. The balance of the increase in amortization expense was related to the amortization of deferred issuance costs associated with the $5 million term loan issued in November 2005. 2006 interest expense also includes prepayment penalties of $516,071 for the early repayment of the Laurus term loans and $266,225 for the cost of terminating the obligation to pay Laurus a portion of the cash flows generated by certain VNPP projects for the next five years. Upon the closing of the PIPE Transaction and repayment of the term loans in June 2006, Laurus elected to convert the outstanding balance on the revolving note into shares of our common stock. The revolving note contained anti-dilution provisions which automatically adjusted the conversion price of the note to $7.00 per share, which is the price at which we issued shares as part of the June 2006 PIPE transaction. The lender would have received 5,557 shares of common stock upon conversion of the revolving note utilizing the conversion price prior to this adjustment, but as a result of the adjustment it received 134,779 shares. The market value of the 126,222 additional shares it received as a result of the adjustment was recorded as interest expense in the amount of $950,865.
          During April 2005 we issued a warrant to purchase 57,143 shares of our common stock to Laurus in exchange for its consent to a private equity issuance and the acquisition of MPG, as well as waiving its right to adjust the conversion price on its convertible term note and convertible revolving note. The warrant was valued at $160,000 using a modified Black-Scholes option pricing model and charged to interest expense during the period.

          Preferred Stock Dividends. Dividend expense recognized during the years ended December 31, 2005 and 2006 is comprised of the following:
                 
Year ended December 31,   2006   2005
 
Accrual of Series E Convertible Preferred dividend
  $ 698,000     $ 1,366,900

    23,085,467        
Deemed dividend associated with change in the exercise price of warrants to purchase shares of common stock
    564,258       484,445  
 
Total
  $ 24,347,725     $ 1,851,345  
 
          Dividend expense increased $22,496,380 to $24,347,725 in 2006, from $1,851,345 in 2005. Dividends accrued on the outstanding Series E Convertible Preferred declined $668,900 to $698,000 in 2006 from $1,366,900 in 2005, due to the conversion of all of the outstanding Series E Convertible Preferred to common stock on June 29, 2006.
          We have issued certain securities in the past that contain anti-dilution provisions (commonly referred to as ratchets) which automatically adjust the exercise or conversion price of the security if we issue any new equity security, or securities convertible into equity, at a price below the exercise or conversion price of the security with the anti-dilution provision. Primarily as a result of our declining stock price, we had three instances during 2006 where we had to adjust the exercise price or the conversion price on one or more securities, each of which resulted in us recording a charge for a non-cash deemed dividend. In January 2006 we issued stock options at the then current market price of $65.10 per share, which was less than the $96.60 exercise price on a warrant held by one of our former Series E Preferred stock holders. Adjusting the exercise price of this warrant resulted in a non-cash deemed dividend of $266,390.
          On June 29, 2006, we issued shares in the PIPE Transaction at $7.00 per share (as discussed in Note 20 to our financial statements). The issuance price of the securities issued in this transaction was less than the conversion price on our Series E Convertible Preferred stock, which contained anti-dilution provisions. Prior to the anti-dilution adjustment the holders of the Series E Convertible Preferred stock would have been entitled to 224,861 shares of common stock on conversion, whereas after the adjustment they were entitled to 3,092,621 shares of common stock on conversion. The market value of the additional 2,867,760 shares receivable upon conversion was recorded as a non-cash deemed dividend in the amount of $23,085,467 on June 29, 2006.
          In addition, a number of the outstanding common stock warrants, most of which were held by former holders of our Series E Convertible Preferred Stock, also contained similar anti-dilution provisions. Prior to the June 2006 PIPE Transaction the exercise price on these warrants ranged from $94.50 per share to $105.00 per share. The issuance of common stock in the June 2006 PIPE Transaction caused the exercise price on these warrants to automatically be reduced to $7.00 per share. We compared the value of the warrants with the old exercise price to the value of the warrants with the reduced exercise price, using a modified Black-Scholes option pricing model and determined that the reduction in the

26


Table of Contents

exercise price had increased the value of the warrants by $297,868. We recognized the expense as a deemed dividend by offsetting charges and credits to additional paid-in capital, without any effect on total stockholders equity.
          On April 28, 2005, in exchange for $5,625,000 in gross proceeds, we issued a package of securities to five institutional investors. The package of securities included 59,524 shares of our common stock and 42-month warrants to purchase 29,762 additional shares of common stock at $110.25 per share. The issuance of these shares caused the exercise price of certain warrants with anti-dilution provisions to automatically adjust to $94.50 per share. We compared the value of the warrants with the old exercise price to the value of the warrants with the reduced exercise price, through the use of a modified Black-Scholes option pricing model, and determined that the reduction in the exercise price had increased the value of the warrants by $484,445. Since these warrants were issued as part of a securities offering the increase in value is considered to be a deemed dividend to the security holders. We recorded the deemed dividend by offsetting charges and credits to additional paid-in capital, without any effect on total stockholders equity.
Liquidity and Capital Resources
          During the twelve-month period ended December 31, 2007 we incurred a net loss of $15.6 million and used $6.8 million of cash for operating activities. We have taken steps to improve our current liquidity and provide the growth capital necessary to fund our plan for 2008 and for future growth.
          As of December 31, 2007, we had cash and cash equivalents of $4,780,701, compared to cash and cash equivalents of $4,663,618 on December 31, 2006. Our contractual obligations as of December 31, 2007 totaled $9,186,480, and include: $6,909,932 of debt (includes expected interest payments of $1,077,993); $870,541 in office leases; and $2,634,000 under various employment agreements.
          Our principal cash requirements are for operating expenses, including employee costs, the costs related to research and development, the cost of outside services including those providing contract manufacturing, accounting, legal, engineering and electrical contracting services, and the funding of inventory and accounts receivable, and capital expenditures. We have financed our operations since inception primarily through the private placement of our common and preferred stock, as well as through various forms of secured debt.

2007 Compared to 2006
          Net cash increased $117,083 and $434,468 during the years ended December 31, 2007 and 2006, respectively.
Operating Activities
          Operating activities consumed cash of $6,774,805 during the year ended December 31, 2007 as compared to consuming cash of $6,248,085 during the year ended December 31, 2006.
          Whether cash is consumed or generated by operating activities is a function of the profitability of our operations and changes in working capital. To get a better understanding of cash sources and uses, we like to split the cash used or provided by operating activities into two pieces: the cash consumed (or generated) by operating activities before changes in working capital; and the cash consumed (or generated) from changes in working capital.
          The cash consumed by operating activities before changes in working capital was $3,846,148 during 2007, a $1,777,930 or 32% reduction from the $5,624,078 consumed during 2006. This reduction was the result of increased sales and improvements in our gross profit during 2007. We believe that we will see additional reductions in the cash consumed by operating activities before changes in working capital if our revenue and profitability continue to improve as we believe they will, to the point that our operations will begin to generate cash before changes in working capital in future periods.
          Changes in working capital consumed $2,928,657 during 2007 as compared to consuming $624,007 during 2006. The increase in working capital was the result of the impact of higher sales during 2007, particularly during the fourth quarter of 2007. We expect our working capital requirements to continue to increase with increases in our sales in future periods, though we hope improvements in our receivables turnover and reductions in our inventory will keep the growth in working capital to a rate that is lower than the growth of our future sales.
Investing Activities
          Investing activities consumed $1,217,834 during 2007 as compared to consuming $4,264,930 during 2006. During 2007 we acquired the assets and assumed certain liabilities of Texas Energy Products and Preferred Lighting in two separate transactions. The cost of the acquisitions, including transaction costs, net of cash acquired was $703,539. During 2006 we acquired Parke P.A.N.D.A. Corporation and Kapadia Consulting for $4,098,377, including cash consideration and transaction costs, net of the cash acquired. Also during 2006 we sold all of the stock of Great Lakes Controlled Energy Corporation to the former owners of that company. Great Lakes’ cash balances of $83,586 were transferred with the sale of the company. Fixed asset purchases increased $431,328 to $514,295 during 2007 from $82,967 during 2006. The increase was primarily related to purchases of additional delivery vehicles required to support our increased level of business activity and acquisition of a new accounting system and related hardware.
Financing Activities
          Financing activities generated cash of $8,109,722 during 2007 as compared to generating $10,947,483 during 2006. In April 2007 we received the proceeds from a stockholder rights offering which raised $2,999,632 and incurred issuance costs of $248,293. During May and June of 2007 we raised $5,000,000 through the issuance of subordinated convertible term notes to a group of eight investors, incurring issuance costs of $8,572 in the process. We also borrowed $171,440 during 2007 to

fund the purchase of new delivery vehicles, made scheduled payments of $56,592 on our mortgage and vehicle loans and received $252,107 from the exercise of options and warrants.
2006 Compared to 2005
          Net cash increased $434,468 and $2,439,342 during the years ended December 31, 2006 and 2005, respectively.
Operating Activities
          The net cash consumed in operating activities declined $708,557 or 10% to $6,248,085 in 2006 compared to $6,956,642 in 2005. The cash consumed before changes in working capital increased $209,099 or 4% to $5,624,078 in 2006 compared to $5,414,979 in 2005. The increase in cash consumed was primarily the result of our net loss.
          The cash consumed by working capital declined 60% or $917,656 to $624,007 in 2006 from $1,541,663 consumed in 2005. Contributing to this reduction were improvements in accounts receivable collections, reductions in inventories and the use of the advance to suppliers.
Investing Activities
          Cash consumed in investing activities increased $2,083,084 to $4,264,930 in 2006 from $2,181,846 in 2005. During 2006 we used cash of $4,098,377 to fund the acquisitions of Parke and Kapadia. As part of the acquisition of Parke we paid the selling stockholder $2.72 million in cash and incurred expenses related to the transaction of $145,605, which was partially offset by cash balances of $1,710 acquired as part of the transaction. Cash used to fund the Kapadia acquisition included $1,250,000 for the cash portion of the purchase consideration and $31,811 for expenses, partially offset by $47,329 of cash acquired in the transaction. We sold all of the stock of Great Lakes Controlled Energy Corporation to the former owners of that company in March 2006. Great Lakes’ cash balances of $83,586 were transferred with the sale of the company. We also invested $82,967 in property, plant and equipment during the year, most of which was associated with purchases of computer equipment for new employees and service vehicles for use in our Energy Services segment
          During 2005, we used $1,632,972 for the acquisition of Maximum Performance Group, including $1,632,078 paid to the selling shareholders, and $137,386 of transaction costs less cash acquired of $136,492. We also invested $478,249 in VNPP assets and purchased furniture, equipment and vehicles totaling $70,625.
Financing Activities
          During 2006 we generated net cash of $10,947,483 through financing activities as compared to generating $11,577,830 of net cash during 2005. In June 2006 we raised $17,875,000 in gross proceeds through the sale of our common stock, while incurring $115,107 in costs related to the issuance. We used $5,038,030 million of the proceeds to pre-pay the principal on two Laurus convertible term loans and Laurus converted $943,455 outstanding on the revolving note to common stock. Also during 2006 we used $1,056,545 to pay down our revolver, $317,835 for scheduled principal payments and $400,000 to pay off the balance on a revolving line credit assumed as part of the acquisition of Parke.

LIQUIDITY
          Our primary sources of liquidity are our available cash reserves of $4,780,701 and a $3 million revolving credit note which was arranged in March 2008. This new revolving credit note matures on March 31, 2009 and bears interest at 17% per annum, with 12% payable in cash and the remaining 5% to be capitalized and added to the principal balance on the note. The note also requires the payment of an unused funds fee of 4% per annum on the unused portion of the note. We may borrow any amount, at any time during the term of the note as long as it is not in default at the time of the advance.
          During fiscal 2007, operating activities consumed cash of $6.8 million.
          Our ability to continue to expand the sales of our products and services will require the continued commitment of significant funds. The actual timing and amount of our future funding requirements will depend on many factors, including the amount, timing and profitability of future revenues, working capital requirements, the level and amount of product marketing and sales efforts and the magnitude of research and development, among other things.
          We have raised a significant amount of capital since our formation through the issuance of shares of our common and preferred stock and notes, which has allowed us acquire companies and to continue to execute our business plan. Most of these funds have been consumed by operating activities, either to fund our losses or for working capital requirements. In an attempt to move the Company to a position where it can start to generate positive cash flow our management has set the following key strategies for cash flow improvement in 2008:
    Focus on increasing the sales and profitability of our products and services. During the past two years we have increased our revenue by $15,787,701, or 427% and we saw our gross profit increase from $1,575 to $4,398,720. This improvement in our gross profit was largely offset by $7,708,878 increase in our SG&A ($3,982,147 excluding non-cash share based compensation) over the period, the result of acquisitions and the addition of sales and administrative support personnel. However, we believe that we have the infrastructure in place to support a doubling of revenue in 2008, without the need to increase our headcount significantly from current levels. If we can achieve this, we believe we will significantly reduce or eliminate the cash consumed from operating activities, before changes in working capital.
 
    Turn around the performance of our Energy Technology segment. Largely as a result of lower than expected sales, our Energy Technology segment recorded an operating loss of approximately $8.2 million during 2007, or 55% of our total operating loss. Part of the failure to achieve scale in this business is due to delays in getting a new version of the eMAC into production. We have taken steps to address this issue and hope that the new version of the eMAC will be available during the second half of 2008. We have secured a supply of discontinued parts to allow us to continue to service and sell to existing customers on a limited basis until the new version is available. In the meantime, we have taken steps to reduce the overhead costs of this segment to better align them with the anticipated level of business activity. Based on marketing studies commissioned in 2007, and our experience marketing the product since forming Lime Energy, we believe there is a good market for this segment’s products and we have an established base of customers to build upon. We are committed to turning around the performance of this segment and are carefully reviewing all of our alternatives for this business.
 
    Aggressively manage our costs in order to conserve cash. The prudent use of the capital resources available to us remains one of our top priorities. We are constantly reviewing our operations looking for more efficient ways to achieve our objectives.

30


Table of Contents

          We believe that if we are successful in achieving these priorities we should have sufficient liquidity to allow us to operate until our operations turn cash flow positive. If we are not able to achieve some or all of these priorities, we may begin to experience a liquidity shortage in the latter half of 2008 which could force us to raise additional capital, scale back our growth plans, or in the worst case cease operations.
          If in the future we raise additional capital (which may require stockholder approval), our existing stockholders, to the extent they do not participate in the capital raise, will likely experience dilution of their present equity ownership position and voting rights, depending upon the number of shares issued and the terms and conditions of the issuance. If we raise capital through the issuance of additional equity, the new equity securities issued may have rights, preferences or privileges senior to those of our common stock.

Recent Accounting Pronouncements
     In July 2006, the FASB issued Interpretation No. 48, “Accounting for Uncertainty in Income Taxes, an interpretation of FASB Statement No. 109” (“FIN 48”). FIN 48 provides guidance on the financial statement recognition and measurement of a tax position taken or expected to be taken in a return. FIN 48 requires that companies recognize in their financial statements the impact of a tax position if that position more likely than not will be sustained on an audit, based on the technical merits of the position. FIN 48 also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosures and transition provisions. We adopted FIN 48 on January 1, 2007. As a result of the implementation of FIN 48, no adjustment to retained earnings was made.
     Our subsidiaries file income tax returns in various tax jurisdictions, including the United States and certain U.S. states. We had substantially concluded all US Federal and State income tax matters for years up to and including 2001.
     We recorded a valuation allowance equaling the deferred tax asset due to the uncertainty of our realization in the future. At December 31, 2007, we had US federal net operating loss carryforwards available to offset future taxable income of approximately $75 million, which expire in the years 2018 through 2026. Under section 382 of the Internal Revenue Code of 1986, as amended, the utilization of US net operating loss carryforwards may be limited under the change in stock ownership rules of the IRC. As a result of ownership changes as defined by Section 382, which have occurred at various points in our history, we believe utilization of our net operating loss carryforwards will likely be significantly limited under certain circumstances. We are currently in the process of calculating the potential Section 382 limitations.
     Our policy is to recognize interest and penalties related to income tax matters in interest and income tax expense respectively. There were no interest and penalties related to income taxes recorded at January 1, 2007, the date of adoption of FIN 48.
          In September 2006, the FASB issued Statement of Financial Accounting Standards, Fair Value Measurements (“Statement No. 157”). Statement No. 157 defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles and expands disclosures about fair value measurements. The statement does not require new fair value measurements, but is applied to the extent that other accounting pronouncements require or permit fair value measurements. The statement emphasizes that fair value is a market-based measurement that should be determined based on the assumptions that market participants would use in pricing an asset or liability. Companies will be required to disclose the extent to which fair value is used to measure assets and liabilities, the inputs used to develop the measurements, and the effect of certain of the measurements on earnings (or changes in net assets) for the period. Certain requirements of Statement No. 157 are required for fiscal years beginning after November 15, 2007, and interim periods within those fiscal years. The effective date for other requirements of Statement No. 157 has been deferred for one year by the FASB. The Company does not expect adoption of the sections of Statement No. 157 which are effective for fiscal years beginning after

31


Table of Contents

November 15, 2007 to have a material effect on the Company’s consolidated financial statements. We are currently evaluating the impact of the delayed Sections of Statement No. 157 on its consolidated financial statements, but has not yet determined the impact of its adoption.
     In February 2007, the FASB issued Statement of Financial Accounting Standards The Fair Value Option for Financial Assets and Liabilities (“Statement No. 159”). Statement No. 159 will become effective as of the beginning of the first fiscal year beginning after November 15, 2007. Statement No. 159 provides companies with an option to report selected financial assets and liabilities at fair value that are not currently required to be measured at fair value. Accordingly, companies would then be required to report unrealized gains and losses on these items in earnings at each subsequent reporting date. The objective is to improve financial reporting by providing companies with the opportunity to mitigate volatility in reported earnings caused by measuring related assets and liabilities differently. Statement No. 159 also establishes presentation and disclosure requirements designed to facilitate comparisons between companies that choose different measurement attributes for similar types of assets and liabilities. The adoption of Statement No. 159 in the first quarter of 2008 is not expected to have a material impact on our consolidated financial statements as we do not expect to elect the fair value option for any financial assets or liabilities.
     In December 2007, the FASB issued Statement No. 141 (Revised 2007), Business Combinations (“Statement No. 141R”), effective prospectively to business combinations for which the acquisition date is on or after the beginning of the first annual reporting period beginning on or after December 15, 2008. Statement No. 141R establishes principles and requirements on how an acquirer recognizes and measures in its financial statements identifiable assets acquired, liabilities assumed, noncontrolling interests in the acquiree, goodwill or gain from a bargain purchase and accounting for transaction costs. Additionally, Statement No. 141R determines what information must be disclosed to enable users of the financial statements to evaluate the nature and financial effects of the business combination. We will adopt Statement No. 141R on January 1, 2009.
     In December 2007, the FASB issued Statement No. 160, Noncontrolling Interests in Consolidated Financial Statements—an amendment of ARB No. 51. (“Statement No. 160”) Statement No. 160 requires entities to report noncontrolling (minority) interests as a component of shareholders’ equity on the balance sheet; include all earnings of a consolidated subsidiary in consolidated results of operations; and treat all transactions between a parent and its noncontrolling interest as equity transactions provided the parent does not lose control. Statement No. 160 is effective for fiscal years beginning on or after December 15, 2008, must be adopted concurrently with SFAS 141R, and adoption is prospective only; however, presentation and disclosure requirements described above must be applied retrospectively. We are currently evaluating the impact that Statement No. 160 will have on our financial statements and disclosures.
Item 7A.   Quantitative and Qualitative Disclosures About Market Risk.
          The only significant exposure we have to market risk is the risk of changes in market interest rates. The interest rate on our mortgage is variable and changes with changes in the prime rate. The interest rate on the mortgage is equal to the prime rate plus 1/2%. As of December 31, 2007, the prime rate was 7.25%. If the prime rate were to increase 1 percentage point, the aggregate annual interest cost on the mortgage would increase by approximately $4,900.

Item 9A(T). Controls and Procedures.
          The Company maintains disclosure controls and procedures that are designed to ensure that information required to be disclosed in the Company’s Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to the Company’s management, including its Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.
          As required by SEC Rule 13a-15(b), the Company carried out an evaluation, under the supervision and with the participation of the Company’s management, including the Company’s Chief Executive Officer and the Company’s Chief Financial Officer, of the effectiveness of the design and operation of the Company’s disclosure controls and procedures as of the end of the period covered by this report. Based on the foregoing, the Company’s Chief Executive Officer and Chief Financial Officer concluded that the Company’s disclosure controls and procedures were effective.
Management’s Annual Report on Internal Control Over Financial Reporting
          Our management is responsible for establishing and maintaining adequate internal control over financial reporting for the Company. Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of our financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America. Internal control over financial reporting includes policies and procedures for maintaining records that in reasonable detail accurately and fairly reflect our transactions; providing reasonable assurance that transactions are recorded as necessary for the preparation of our financial statements; providing reasonable assurance that receipts and expenditures of the Company are made in accordance with management authorization; and providing reasonable assurance that unauthorized acquisition, use or disposition of Company assets that could have a material effect on our financial statements would be prevented or detected on a timely basis. Because of inherent limitations, internal control over financial reporting is not intended to provide absolute assurance that a misstatement of our financial statements would be prevented or detected.
          Management conducted an evaluation of the effectiveness of our internal control over financial reporting based on the framework in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this evaluation, management concluded that the Company’s internal control over financial reporting was effective as of December 31, 2007.
          This annual report does not include an attestation report of the company’s registered public accounting firm regarding internal control over financial reporting. Management’s report was not subject to attestation by the company’s registered public accounting firm pursuant to temporary rules of the Securities and Exchange Commission that permit the company to provide only management’s report in this annual report.
Changes in Internal Control Over Financial Reporting
          There were no changes in our internal control over financial reporting during the quarter ended December 31, 2007 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Report of Independent Registered Public Accounting Firm
Lime Energy Co.
Elk Grove Village, Illinois
We have audited the accompanying consolidated balance sheets of Lime Energy Co. as of December 31, 2007 and 2006, and the related consolidated statements of operations, stockholders’ equity and cash flows for each of the three years in the period ended December 31, 2007. We have also audited the schedule in the accompanying index. These financial statements and schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements and schedule based on our audits.
We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and schedule are free of material misstatement. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and schedule, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements and schedule. We believe that our audits provide a reasonable basis for our opinion.
In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Lime Energy Co. at December 31, 2007 and 2006, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2007, in conformity with accounting principles generally accepted in the United States of America.
Also, in our opinion, the schedule presents fairly, in all material respects, the information set forth therein.
As discussed in Note 3 to the consolidated financial statements, effective January 1, 2006, the Company adopted Statement of Financial Accounting Standards No. 123R, “Share- Based Payments” using the modified prospective transition method.

Note 3 — Summary of Significant Accounting Policies
     Principles of Consolidation
     The consolidated financial statements include the accounts of Lime Energy Co. and its wholly owned subsidiaries, Maximum Performance Group, Inc., Parke Industries LLC, Kapadia Energy Services, Inc., Lime Midwest, Inc., Texas Energy Products, Inc., Preferred Lighting, Inc. and Lime Finance, Inc. All significant intercompany balances and transactions have been eliminated.
     Use of Estimates
     The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
     Cash and Cash Equivalents
     The Company considers highly liquid investments with a maturity of three months or less when purchased to be cash equivalents.
     Concentration of Risk
     The Company’s customers are primarily owners of, or tenants of, commercial and industrial buildings. One customer accounted for approximately 10% of the Company’s consolidated billings during the year ended December 31, 2007. Three customers each accounted for approximately 13% of the Company’s consolidated billings during the year ended December 31, 2006, while two customers

Notes to Consolidated Financial Statements
accounted for approximately 37% and 11% of the Company’s consolidated billings during the year ended December 31, 2005.
     The Company purchases its materials from a variety of suppliers and continues to seek out alternate suppliers for critical components so that it can be assured that its sales will not be interrupted by the inability of a single supplier to deliver product. During the year ended December 31, 2007, two suppliers accounted for approximately 17% and 10% of the company’s purchases, respectively. During the year ended December 31, 2006, one supplier accounted for approximately 12% of the Company’s total purchases while no single supplier accounted for more than 10% of the Company’s total purchases during the year ended December 31, 2005.
     The Company maintains cash and cash equivalents in accounts with a financial institution in excess of the amount insured by the Federal Deposit Insurance Corporation. The Company monitors the financial stability of this institution regularly and management does not believe there is significant credit risk associated with deposits in excess of federally insured amounts.
     Allowance for Doubtful Accounts
     The Company records an allowance for doubtful accounts based on specifically identified amounts that it believes to be uncollectible. If actual collections experience changes, revisions to the allowance may be required. After all attempts to collect a receivable have failed, the receivable is written off against the allowance. Based on the information available to it, the Company believes its allowance for doubtful accounts is adequate. However, actual write-offs might exceed the recorded allowance.
     Inventories
     Inventories are stated at the lower of cost or market. Cost is determined utilizing the first-in, first-out (FIFO) method.
     Properties & Equipment
     Property and equipment are stated at cost. For financial reporting purposes depreciation is computed over the estimated useful lives of the assets by the straight-line method over the following lives:
     
Buildings
  39 years
Office equipment
  3 — 5 years
Furniture
  5 — 10 years
Equipment
  3 — 5 years
Transportation equipment
  3 — 5 years
     Cost in Excess of Assets Acquired
     Goodwill represents the purchase price in excess of the fair value of assets acquired in business combinations. Statement of Financial Accounting Standards (SFAS) No. 142, “Goodwill and Other Intangible Assets”, requires the Company to assess goodwill for impairment at least annually in the absence of an indicator of possible impairment and immediately upon an indicator of possible impairment. During the fourth quarter of 2004, the Company completed its annual assessment of impairment regarding the goodwill recorded for its Building Control and Automation segment. That assessment, supported by independent appraisals of the fair value of the segment, did not identify any impairment. However, the 2005 appraisal, made using customary valuation methodologies, including discounted cash flows and fundamental analysis, did reveal an impairment. Further supporting this

Notes to Consolidated Financial Statements
assessment, in February 2006, the Company signed a letter of intent to sell the segment for an amount below the carrying value of the reporting unit. The decline in fair value of the Building Control and Automation segment was primarily the result of the segment failing to meet earnings expectations, due in part to strong competition in its markets. As a result of this decline in fair value, the Company recorded an impairment loss of $242,830 during the year ended December 31, 2005.
     During the fourth quarter of 2007, the Company updated its projections for portions of the Energy Services and Energy Technology businesses and estimated the fair value based on the discounted current value of the estimated future cash flows. It then compared the implied fair values of the reporting units to their carrying values. The analysis did not identify any impairment for the Energy Services business, but did determine that the value of the Energy Technology’s goodwill was impaired. The decline in the fair value of the Energy Technology segment was primarily the result of lower than expected sales of the eMAC line of HVAC controllers, in large part due to delays in product enhancements designed to replace discontinued components and add cellular communication capabilities. As a result of the decline in the fair value, the Company recorded an impairment loss of $4,181,969 during the fourth quarter of 2007.
     It is possible that upon completion of future impairment tests, as the result of changes in facts or circumstances, the Company may have to take additional charges to recognize a further write-down of the value of its acquisitions to their estimated fair values.
     Deferred Financing Costs
     The Company incurred $8,572 in costs in connection with the issuance of the convertible subordinated notes during 2007. This expense has been capitalized to deferred financing costs and is being amortized over the three year term of the debt using the effective interest method.
     The Company capitalized costs incurred in arranging its convertible revolving credit facility and convertible term loans as deferred financing. These deferred financing costs were being amortized over the life of the related convertible term loan using the effective interest method. On June 29, 2006 the Company prepaid the outstanding balance on its two convertible term loans and the holder of the convertible notes, elected to convert the outstanding balance of the convertible revolving credit facility into common stock. Upon the repayment and conversion of these notes in June 2006 the Company was required to recognize as interest expense the remaining unamortized balances of the capitalized issuance costs and the debt discount of $231,281. Amortization of the deferred financing costs included in interest expense totaled $1,687, $299,964 and $93,774 in 2007, 2006 and 2005, respectively.
     Impairment of Long-Lived Assets
     The Company records impairment losses on long-lived assets used in operations when events and circumstances indicate that the assets might be impaired and the undiscounted cash flows estimated to be generated by those assets are less than the carrying amount of those items. The Company’s cash flow estimates are based on historical results adjusted to reflect its best estimate of future market and operating conditions. The net carrying value of assets not recoverable is reduced to fair value. These estimates of fair value represent management’s best estimate based on industry trends and reference to market rates and transactions.

Notes to Consolidated Financial Statements
     During 2006, the Company terminated its Virtual Negawatt Power Program (“VNPP”) in northern Illinois, due to the high capital requirements of the program, changes in lighting technology and changes in the Company’s business plan. As a result of this decision, it reduced the carrying value of its VNPP assets to $0 and recorded an impairment charge of $1,183,525.
     Revenue Recognition
     The Company recognizes revenue when all four of the following criteria are met: (i) persuasive evidence has been received that an arrangement exists; (ii) delivery of the products and/or services has occurred; (iii) the selling price is fixed or determinable; and (iv) collectibility is reasonably assured. In addition, the Company follows the provisions of the Securities and Exchange Commission’s Staff Accounting Bulletin No. 104, Revenue Recognition, which sets forth guidelines in the timing of revenue recognition based upon factors such as passage of title, installation, payments and customer acceptance. Any amounts received prior to satisfying the Company’s revenue recognition criteria is recorded as deferred revenue in the accompanying balance sheet.
     The Company accounts for revenue on most of its long-term contracts on the completed contract method, whereby revenue is recognized once the project is substantially complete. However, revenue on some long-term contracts is recorded under the percentage of completion method in conjunction with the cost-to-cost method of measuring the extent of progress toward completion consistent with the AICPA’s Statement of Position 81-1 (SOP 81-1). Any anticipated losses on contracts are charged to operations as soon as they are determinable.
     Billings on contracts that do not meet the Company’s revenue recognition policy requirements for which it has been paid or has a valid account receivable are recorded as deferred revenue. Deferred revenue for billings that did not meet the Company’s revenue recognition policies totaled $636,867 and $294,430 as of December 31, 2007 and 2006, respectively.
     The Company’s MPG subsidiary often bundles contracts to provide monitoring services and Internet access with the sale of its eMAC hardware. As a result, these sales are considered to be contracts with multiple deliverables which at the time the hardware is delivered and installed includes undelivered services essential to the functionality of the product. Accordingly, the Company defers the revenue for the product and services and the cost of the equipment and installation and recognizes them over the term of the monitoring contract. The monitoring contracts vary in length from 1 month to 5 years. Deferred revenue included $1,139,342 and $1,421,996 as of December 31, 2007 and 2006, respectively, related to these contracts.
     Costs of Uncompleted Contracts in Excess of Related Billings
     As of December 31, 2007, the Company had several customer projects underway for which it will recognize revenue upon completion of the project. Expenses related to these uncompleted projects have been recorded as a current asset titled “Costs of Uncompleted Contracts in Excess of Related Billings.” These expenses will be recognized as the related projects are completed and revenue is recognized. The Company had costs in excess of related billings of $952,997 and $0 at December 31, 2007 and 2006, respectively. It is expected that the majority of the projects underway as of the end of 2007 will be completed during the first quarter of 2008.

     Shipping and Handling Costs
     The Company classifies freight costs billed to customers as revenue. Costs related to freight are classified as cost of sales.
     Research and Development Costs
     Research and development costs are charged to operations when incurred and are included in selling, general and administrative expenses. Total research and development costs charged to operations were approximately $700,000, $535,000 and $395,000 for the periods ended December 31, 2007, 2006 and 2005, respectively.
     Advertising, Marketing and Promotional Costs
     Expenditures on advertising, marketing and promotions are charged to operations in the period incurred and totaled $168,000, $117,000 and $7,000 for the periods ended December 31, 2007, 2006 and 2005, respectively.
     Income Taxes
     Income taxes are accounted for under the asset and liability method. Deferred income taxes are recognized for the tax consequences in future years of the differences between the tax basis of assets and liabilities and their financial reporting amounts at each period end based on enacted tax laws and statutory tax rates applicable to the periods in which the differences are expected to affect taxable earnings. Valuation allowances are established when necessary to reduce deferred tax assets to the amount more likely than not to be realized.
     Net Loss Per Share
     The Company computes loss per share under Statement of Financial Accounting Standards No. 128, “Earnings Per Share.” The statement requires presentation of two amounts; basic and diluted loss per share. Basic loss per share is computed by dividing the loss available to common stockholders by the weighted average common shares outstanding. Diluted earnings per share would include all common stock equivalents unless anti-dilutive. The Company has not included the outstanding options, warrants, convertible preferred stock or convertible debt as common stock equivalents because the effect would be antidilutive.
     The following table sets forth the weighted average shares issuable upon exercise of outstanding options and warrants and conversion of preferred stock and convertible debt that is not included in the basic and diluted net loss per share available to common stockholders:
                         
December 31,   2007     2006     2005  
 
Weighted average shares issuable upon exercise of outstanding options
    1,744,873       778,310       111,623  
Weighted average shares issuable upon exercise of outstanding warrants

     Fair Value of Financial Instruments
     The carrying amounts reported in the consolidated balance sheets for cash, accounts receivable, accounts payable and accrued expenses approximate fair value because of the short-term nature of these amounts. The Company’s long-term debt approximates fair value based on instruments with similar terms.
     Stock-based Compensation
     The Company has a stock incentive plan that provides for stock-based employee compensation, including the granting of stock options and shares of restricted stock, to certain key employees. The plan is more fully described in Note 25. Effective January 1, 2006, the Company adopted Statement of Financial Accounting Standards No. 123(R), “Share-based Payment” (“SFAS 123(R)”), which requires, among other things, that compensation expense be recognized for employee stock options. Prior to the adoption of SFAS 123(R), the Company accounted for stock compensation using the recognition and measurement principles of Accounting Principles Board Opinion No. 25, “Accounting for Stock Issued to Employees,” and related Interpretations. Under that method, compensation expense was recorded only if the current market price of the underlying stock on the date of grant exceeded the option exercise price. Since stock options are granted at exercise prices that are greater than or equal the market value of the underlying common stock on the date of grant under the Company’s stock incentive plan, no compensation expense related to stock options was recorded in the Consolidated Statements of Operations prior to January 1, 2006.
     On January 1, 2006, the Company adopted SFAS No. 123(R), which requires companies to record stock compensation expense for equity-based awards granted, including stock options and restricted stock unit grants, over the service period of the equity-based award based on the fair value of the award at the date of grant. The Company recognized $3,726,731 and $4,828,955 of stock compensation expense during the years ended December 31, 2007 and 2006, respectively.
     The following table illustrates the effect on the net loss and earnings per share if the Company had applied the fair value recognition provisions of SFAS No. 123 to stock-based compensation during the year ended December 31, 2005:

     For purposes of this pro forma disclosure the fair value of each option granted has been estimated on the date of grant using a modified Black-Scholes option-pricing model with the following weighted-average assumptions used for the grants:
         
December 31,   2005  
 
Risk-free interest rate
    2.27 %
Expected volatility
    65 %
Expected life (years)
    9.1  
Expected dividend yield
    0 %
 
     The weighted-average fair value of options granted was $4.76 in 2005. For purposes of pro forma disclosures, the estimated fair value of the options is amortized over the options’ vesting period.
     Warranty Obligations
     The Company warrants to the purchasers of its products that the product will be free of defects in material and workmanship for one year from the date of installation. In addition, some customers have purchased extended warranties for the Company’s products that extend the base warranty period. The Company records the estimated cost that may be incurred under its warranties at the time the product revenue is recognized based upon the relationship between historical and anticipated warranty costs and sales volumes. The Company periodically assesses the adequacy of its recorded warranty liability and adjusts the amounts as necessary. While the Company believes that its estimated liability for product warranties is adequate and that the judgment applied is appropriate, the estimated liability for product warranties could differ materially from actual future warranty costs. See Note 10 for additional information about the Company’s warranty liability.
     Insurance Reserves
     In October 2005, the Company implemented a partially self-funded health insurance program for its employees. Under the program the Company is responsible for the first $35,000 of each individual claim, but its exposure is limited on a monthly and cumulative basis through insurance provided by a third party insurance company. The Company accrues on a monthly basis an amount sufficient to cover its maximum exposure under the program. At the end of each plan year it assesses the adequacy of the reserve based on its claims history and adjusts the reserve as necessary. It had accrued liabilities of $102,665, $45,423 and $57,231 as of December 31, 2007, 2006 and 2005, respectively, to cover future claims under the program.
     Recent Accounting Pronouncements
     In July 2006, the FASB issued Interpretation No. 48, “Accounting for Uncertainty in Income Taxes, an interpretation of FASB Statement No. 109” (“FIN 48”). FIN 48 provides guidance on the financial statement recognition and measurement of a tax position taken or expected to be taken in a return. FIN 48 requires that companies recognize in their financial statements the impact of a tax position if that position more likely than not will be sustained on an audit, based on the technical merits of the position. FIN 48 also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosures and transition provisions. The Company adopted FIN 48 on January 1, 2007. As a result of the implementation of FIN 48, no adjustment to retained earnings was made.

Notes to Consolidated Financial Statements
The Company’s subsidiaries file income tax returns in various tax jurisdictions, including the United States and certain U.S. states. The Company has substantially concluded all US Federal and State income tax matters for years up to and including 2001.
     The Company has recorded a valuation allowance equaling the deferred tax asset due to the uncertainty of its realization in the future. At December 31, 2007, the Company had US federal net operating loss carryforwards available to offset future taxable income of approximately $75 million, which expire in the years 2018 through 2026. Under section 382 of the Internal Revenue Code of 1986, as amended, the utilization of US net operating loss carryforwards may be limited under the change in stock ownership rules of the IRC. As a result of ownership changes as defined by Section 382, which have occurred at various points in the Company’s history, it believes utilization of its net operating loss carryforwards will likely be significantly limited under certain circumstances. The Company is currently in the process of calculating the potential Section 382 limitations.
     The Company’s policy is to recognize interest and penalties related to income tax matters in interest and income tax expense respectively. There were no interest and penalties related to income taxes recorded at January 1, 2007, the date of adoption of FIN 48.
     In September 2006, the FASB issued Statement of Financial Accounting Standards, Fair Value Measurements (“Statement No. 157”). Statement No. 157 defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles and expands disclosures about fair value measurements. The statement does not require new fair value measurements, but is applied to the extent that other accounting pronouncements require or permit fair value measurements. The statement emphasizes that fair value is a market-based measurement that should be determined based on the assumptions that market participants would use in pricing an asset or liability. Companies will be required to disclose the extent to which fair value is used to measure assets and liabilities, the inputs used to develop the measurements, and the effect of certain of the measurements on earnings (or changes in net assets) for the period. Certain requirements of Statement No. 157 are required for fiscal years beginning after November 15, 2007, and interim periods within those fiscal years. The effective date for other requirements of Statement No. 157 has been deferred for one year by the FASB. The Company does not expect adoption of the sections of Statement No. 157 which are effective for fiscal years beginning after November 15, 2007 to have a material effect on the Company’s consolidated financial statements. The Company is currently evaluating the impact of the delayed Sections of Statement No. 157 on its consolidated financial statements, but is not yet in a position to determine the impact of its adoption.
     In February 2007, the FASB issued Statement of Financial Accounting Standards The Fair Value Option for Financial Assets and Liabilities (“Statement No. 159”). Statement No. 159 will become effective as of the beginning of the first fiscal year beginning after November 15, 2007. Statement No. 159 provides companies with an option to report selected financial assets and liabilities at fair value that are not currently required to be measured at fair value. Accordingly, companies would then be required to report unrealized gains and losses on these items in earnings at each subsequent reporting date. The objective is to improve financial reporting by providing companies with the opportunity to mitigate volatility in reported earnings caused by measuring related assets and liabilities differently. Statement No. 159 also establishes presentation and disclosure requirements designed to facilitate comparisons between companies that choose different measurement attributes for similar types of assets and liabilities. The adoption of Statement No. 159 in the first quarter of 2008 is not expected to have a material impact on the

Company’s consolidated financial statements as it does not expect to elect the fair value option for any financial assets or liabilities.
     In December 2007, the FASB issued Statement No. 141 (Revised 2007), Business Combinations (“Statement No. 141R”), effective prospectively to business combinations for which the acquisition date is on or after the beginning of the first annual reporting period beginning on or after December 15, 2008. Statement No. 141R establishes principles and requirements on how an acquirer recognizes and measures in its financial statements identifiable assets acquired, liabilities assumed, noncontrolling interests in the acquiree, goodwill or gain from a bargain purchase and accounting for transaction costs. Additionally, Statement No. 141R determines what information must be disclosed to enable users of the financial statements to evaluate the nature and financial effects of the business combination. The Company will adopt Statement No. 141R on January 1, 2009.
     In December 2007, the FASB issued Statement No. 160, Noncontrolling Interests in Consolidated Financial Statements—an amendment of ARB No. 51. (“Statement No. 160”) Statement No. 160 requires entities to report noncontrolling (minority) interests as a component of shareholders’ equity on the balance sheet; include all earnings of a consolidated subsidiary in consolidated results of operations; and treat all transactions between a parent and its noncontrolling interest as equity transactions provided the parent does not lose control. Statement No. 160 is effective for fiscal years beginning on or after December 15, 2008, must be adopted concurrently with SFAS 141R, and adoption is prospective only; however, presentation and disclosure requirements described above must be applied retrospectively. The Company is currently evaluating the impact that Statement No. 160 will have on its financial statements and disclosures.
Note 4 — Acquisitions
     Maximum Performance Group, Inc.
     On May 3, 2005, pursuant to an Agreement and Plan of Merger (the “Merger Agreement”) dated as of April 28, 2005, by and among Lime Energy Co., MPG Acquisition Corporation, a wholly-owned subsidiary of Lime Energy (“Merger Subsidiary”), and Maximum Performance Group, Inc.

     Parke P.A.N.D.A. Corporation
Lime Energy Co.
Notes to Consolidated Financial Statements
     On May 19, 2006, Lime Energy entered into an agreement by and among the Company, Parke Acquisition, LLC, a wholly-owned subsidiary of Lime Energy (“Merger Subsidiary”), Parke P.A.N.D.A. Corporation (“Parke”), Daniel W. Parke (a director of Lime Energy) and Daniel W. Parke and Michelle A. Parke as Trustees under The Parke Family Trust, under which on June 30, 2006, the Company acquired Parke pursuant to the merger of Parke with and into Merger Subsidiary, with Merger Subsidiary continuing as the surviving corporation under the name Parke Industries, LLC.
     The merger consideration consisted of $2,720,000 in cash and shares of common stock having the value of $5 million (valuing each share at the $7.00 price used in the private placement of common stock described under Note 22(i)) or 714,286 shares of Lime Energy common stock, all of which was paid to The Parke Family Trust, the sole stockholder of Parke, which is beneficially owned by Daniel Parke and his spouse, Michelle A. Parke, who are also the trustees of such Trust. As a result of the merger, Merger Subsidiary became responsible for the liabilities of Parke, including $400,000 due on its line of credit and approximately $46,000 in various vehicle loans. The acquisition has been recorded using the purchase method of accounting.
     Parke is an energy services provider specializing in the design, engineering and installation of energy efficient lighting upgrades for commercial and industrial users. Parke is headquartered in Glendora, California with sales offices in northern California, and at the time of the acquisition it had 30 employees.
     Dan Parke, the president and founder of Parke continues to serve as the President of Parke and as of June 30, 2006 also assumed the position of President and Chief Operating Officer of Lime Energy. Mr. Parke also continues to serve as a director of Lime Energy.

     The Company has assessed the fair values of assets and liabilities of Parke and allocated the purchase price accordingly. For purposes of the allocation, it has allocated $595,000 of the Parke purchase price to identifiable intangible assets with definitive lives such as customer contracts, sales pipeline and the non-compete agreement with Dan Parke. This amount has been capitalized and will be amortized over the estimated useful life of the related identifiable intangible assets. It also allocated $2,652,000 to the Parke trade name, which was determined to have an indefinite useful life and therefore will not be amortized.

Note 11 — Line of Credit
     On September 11, 2003 the Company closed on a credit facility with Laurus Master Fund, Ltd. (“Laurus”). The facility, which was subsequently amended on August 31, 2004, February 28, 2005 and November 28, 2005, included a $1,000,000 convertible term loan and a $2,000,000 convertible revolving line of credit.
     On June 29, 2006, Laurus exercised its right to convert all of the outstanding balance on the Company’s revolving line of credit of $943,455 plus $7,410 in accrued interest into 135,838 shares of the Company’s common stock, and the line was terminated. The revolving note contained anti-dilution provisions which automatically adjusted the conversion price of the note to $7.00 per share, the price at which the Company issued shares of common stock in the June 2006 PIPE Transaction (as described in

Notes to Consolidated Financial Statements
Note 20). Laurus (if it still chose to convert the note) would have received 8,557 shares of common stock upon conversion of the revolving note utilizing the conversion price prior to this adjustment, but as a result of the adjustment it received 134,779 shares. The market value of the 126,222 additional shares it received as a result of the adjustment (capped at the amount converted including the accrued interest), was recorded as interest expense in the amount of $950,865. On June 29, 2006, the market price of the Company’s common stock was $8.05 per share, as a result the Company recognized an additional $1,112 of non-cash interest expense calculated as the difference between the market price ($8.05) and the conversion price ($7.00) of the 1,059 shares of common stock issued in satisfaction of the accrued interest expense.
Note 12 — Subordinated Convertible Term Notes
     During the second quarter of 2007, eight investors, including Richard Kiphart, the Company’s chairman and largest individual stockholder (collectively the “Investors”), and the Company entered into a loan agreement under which the Investors lent the Company $5 million in the form of subordinated convertible term notes (the “Term Notes”). The Term Notes mature on May 31, 2010, although they may be prepaid at anytime after May 31, 2008 at the Company’s option without penalty, and accrue interest at the rate of 10% per year. Interest is payable quarterly, 50% in cash and 50% in shares of the Company’s common stock valued at the market price of the Company’s common stock on the interest due date. The Term Notes are convertible at any time at the Investors’ election at $7.00 per share and will automatically convert to shares of common stock at $7.00 per share, if, at any time after May 31, 2008 the closing price of the Company’s common stock exceeds $10.50 per share for 20 days in any consecutive 30-day period. The loan agreement provides for acceleration upon the occurrence of typical events of default, including nonpayment, nonperformance, bankruptcy and collateral impairment.
     As part of the transaction, the Company issued the Investors four-year warrants to purchase 206,044 shares of its common stock at $7.28 per share. These warrants were valued at $1,136,537 utilizing a modified-Black Scholes option pricing model utilizing the following assumptions: risk free rate of 4.846%; expected volatility of 93.3%; expected dividend of $0; and expected life of four years.
     The shares issued as part of the quarterly interest payments and issuable upon conversion of the term loan or exercise of the warrants will not be registered for resale, though the Company has given the Investors the right to demand the Company use its best efforts to file as soon as practicable a registration statement to register a minimum of 142,857 issued shares.
     In recording the transaction, the Company allocated the value of the proceeds to the Term Notes and warrants based on their relative fair values. In doing so, it determined that the Term Notes contained a beneficial conversion feature since the fair market value of the common stock issuable upon conversion of the Term Notes (determined on the Term Note issuance date) exceeded the value allocated to the Term Notes of $3,863,463. The Term Notes are convertible into 714,286 shares of common stock, which at the market price of $8.02 per share on date of issuance of the Term Notes was worth $5,730,000. The difference between the market value of the shares issuable upon conversion and the value allocated to the Term Notes of $1,866,537 is considered to be the value of the beneficial conversion feature. This calculation is summarized as follows:

Amortization of the discount of $590,769 was included in interest expense during the year ended December 31, 2007.
     In addition, the Company incurred costs of $8,572 relative to the Term Note offering. These costs have been capitalized and are also being amortized over the term of the Term Notes using the effective interest method.

Note 13 — Convertible Term Loans
     On September 11, 2003, the Company entered into a $1,000,000 convertible Term Loan with Laurus Master Fund, Ltd., which was subsequently amended on August 31, 2004. The term loan was secured by all of the Company’s assets except its real estate; was convertible into the Company’s common stock under certain circumstances at Laurus’ or the Company’s option; required monthly payments of principal and interest; and was schedule to mature on September 1, 2006.
     On November 22, 2005, the Company and Laurus entered into a securities purchase agreement providing for a new four year, $5 million convertible term loan (the “November 2005 Term Loan”). The Company received unrestricted access to the proceeds from the November 2005 Term Loan on November 25, 2005. This term loan was also secured by all of the Company’s assets except its real estate; was convertible into the Company’s common stock under certain circumstances at Laurus’ or the Company’s option; required monthly payments of principal and interest; and was scheduled to mature on November 1, 2009. None of the November 2005 Term Loan was ever converted to common stock.
     As part of the November 2005 Term Loan the Company agreed to split any cash flow generated by the Company’s VNPP and Shared Savings projects, after the payment of related debt, to the extent any portion of the November 2005 Term Loan was used to fund such Projects. In addition, the Company

agreed to continue to pay a portion of the Project Cash Flow to Laurus on a declining basis for five years after repayment of the November 2005 Term Loan.
     In connection with the November 2005 Term Loan, Laurus received warrants to purchase shares of the Company’s common stock valued at $920,000. The value of these warrants were recorded as a discount to the loan and were being amortized over the life of the loan utilizing the effective interest method. In addition, fees and expenses related to the transaction totaling $271,431were recorded as capitalized financing costs and were being amortized over the life of the loan utilizing the effective interest method.
     On June 29, 2006, the Company repaid the outstanding balances on the two term loans held by Laurus, along with accrued interest thereon and related prepayment penalties and fees. The total cash payment to Laurus made on June 29, 2006 was as follows:
         
    Payment  
 
Principal
  $ 5,038,030  
Interest through the date of repayment
    40,568  
Prepayment penalties
    516,071  
Related fees
    6,749  
 
Total payment
  $ 5,601,418  
 
     In conjunction with the repayment Laurus agreed to 1) waive the payment of liquidated damages due as a result of the Company’s failure to register shares of its stock issuable upon conversion of the November 2005 Term Loan as required in the related Securities Purchase Agreement, and 2) terminate the requirement that the Company pay it a portion of the cash flows generated by VNPP and Shared Savings projects following the repayment of the November 2005 Term Loan, in exchange for receipt of 23,014 and 33,071 shares of the Company’s common stock, respectively. The Company valued these shares at $8.05 per share (the market price on the date of issue) and charged $266,225 to interest expense and $185,260 to selling general & administrative expense during 2006.
     Upon the repayment of the term loans the Company was required to recognize as interest expense the unamortized balance of the discount and capitalized financing costs related to these loans of $777,996 and $231,281, respectively.

Deferred tax asset consisting principally of net operating losses
  $ 33,897,000     $ 28,368,000

Total net deferred tax liability
  $ (1,034,000 )   $ (1,034,000 )
 
     The Company has recorded a valuation allowance equaling the deferred tax asset due to the uncertainty of its realization in the future. At December 31, 2007, the Company had U.S. federal net operating loss carryforwards available to offset future taxable income of approximately $75 million, which expire in the years 2018 through 2027. Under Section 382 of the Internal Revenue Code (IRC) of 1986, as amended, the utilization of U.S. net operating loss carryforwards may be limited under the change in stock ownership rules of the IRC. As a result of ownership changes as defined by Section 382, which have occurred at various points in our history, we believe utilization of our net operating loss carryfowards will likely be significantly limited under certain circumstances. The Company is currently in the process of calculating the potential Section 382 limitations on the future us of its net operating loss carryforwards.

     The Company has recorded a valuation allowance of $33.7 million due to the uncertainty of future utilization of the deferred tax assets. In assessing the adequacy of the valuation allowance, the Company determined that there existed a deferred tax liability related to an indefinite-lived intangible, for which the expected reversal was indeterminate. Due to uncertainty of whether this deferred tax liability would reverse prior to expiration of the net operating losses and other deferred tax assets, this liability has not been netted against the Company’s deferred tax assets, resulting in a net deferred tax liability of approximately $1 million as of both December 31, 2007 and 2006.

Note 20 — The June 2006 PIPE Transaction
     On June 29, 2006, the Company entered into a securities purchase agreement with a group of 17 investors (the “PIPE Investors”) pursuant to which it issued to such purchasers an aggregate of 2,553,571 shares of its common stock at a price of $7.00 per share for total gross proceeds of $17,875,000 (the “PIPE Transaction”). Ten of the PIPE Investors, who purchased an aggregate of 1,985,714 shares of common stock in the PIPE Transaction, were holders of Series E Convertible Preferred stock, including three members of the Company’s board of directors (who, together with members of their families, purchased 1,100,000 shares of common stock in the PIPE Transaction). Proceeds from the transaction were used to repay the Company’s outstanding convertible debt and to fund the cash portion of the

consideration of the Parke P.A.N.D.A. Corporation and the Kapadia Consulting, Inc. acquisitions, with the balance used for general corporate purposes.
     A provision of the June 2006 PIPE Transaction required the Company to file and have declared effective by November 3, 2006, a registration statement registering the shares issued as part of the PIPE Transaction. To the extent that it failed to have the registration statement declared effective by this date, the Company was required to pay penalties to the PIPE investors at the rate of 1% per month of the purchase price paid by the investors. Largely as a result of the questions regarding the need to amend its Certificate of Incorporation to effect the 2006 reverse split of its stock, the Company was not able to have the registration statement declared effective until February 14, 2007. All of the investors in the PIPE Transaction agreed to accept shares of the Company’s common stock as payment of this registration penalty. As of December 31, 2006 the Company had accrued $345,583 in penalties related to its failure to register these shares. The accrued penalties, along with $268,125 of penalties for the period from January 1, 2007 through February 14, 2007 (when the registration was declared effective), were satisfied through the issuance of 87,673 shares of common stock in January and February 2007.
Note 21 — The Series E Conversion
     In connection with the June 2006 PIPE Transaction, the holders of the Series E Preferred agreed to convert all of their shares of Series E Preferred into common stock, and agreed that, upon the conversion, all agreements related to the Preferred Stock would be terminated. As a result of the conversion, all special approval rights related to the Preferred Stock, including the right to a liquidation preference, were terminated. All of the shares of Series E Convertible Preferred which were converted to common stock have been cancelled.
     Prior to the June 2006 PIPE Transaction, the Series E Preferred stock was convertible into the Company’s common stock at $105.00 per share. However, the Series E Preferred contained anti-dilution provisions which required automatic reduction of the conversion price of the Series E Preferred to the price of a new issuance if the Company issued stock or securities convertible into common stock at a price below the Series E Preferred conversion price then in effect. Because the Company issued common stock in the June 2006 PIPE Transaction at $7.00 per share, the Series E Preferred conversion price was automatically reduced to $7.00 per share. Prior to this adjustment the holders of the Series E Convertible Preferred stock would have been entitled to 224,861 shares of common stock on conversion, whereas as a result of this adjustment on conversion they actually received 3,092,621 shares of common stock. The market value of the additional 2,867,760 shares issuable upon conversion of the Series E was recorded as a non-cash deemed dividend in the amount of $23,085,467 on June 29, 2006.

2005 Transactions
a)   During 2005, two holders of the Company’s Series E Convertible Preferred Stock converted 2,167 shares of Series E Convertible Preferred Stock into 2,064 shares of common stock.
 
b)   During 2005, the Company issued the following warrants:
    On April 28, 2005, Laurus Master Fund, Ltd. received a warrant to purchase 3,810 shares of common stock in exchange for its consent to the Company entering into the PIPE Transaction described under c) below and acquiring MPG, as well as waiving its right to adjust the conversion price on the Company’s convertible term note and convertible revolving note. The warrant has an exercise price of $105.00 per share and a term of five years. The warrant was valued at $160,000 using a modified Black-Scholes option pricing model utilizing the following assumptions: risk free rate of 2.941%; expected volatility of 43.7%; expected dividend of $0; and expected life of 5 years. The value of the warrant was charged to interest expense during 2005.
 
    Various parties received warrants to purchase 4,191 shares of the Company’s common stock with exercise prices between $105.00 and $108.15 per share and terms of three to ten years. The warrants were valued collectively at $159,800 using a modified Black-Scholes option pricing model utilizing the following assumptions (depending on the warrant being valued): risk free rate of 2.366% to 3.029%; expected volatility of 40.7% to 46.5%; an expected dividend of $0; and an expected life of 3 to 10 years. The values of the warrants were charged to operations during the 2005.
c)   On April 28, 2005 the Company issued to five (5) institutional investors, for an aggregate gross purchase price of $5,625,000, 59,524 shares of its common stock and 42 month warrants to purchase 29,762 additional shares of common stock at $110.25 per share. Net proceeds from the transaction were approximately $5,413,000, of which approximately $1,644,000 was used to fund the acquisition of Maximum Performance Group, Inc. The balance of the proceeds were used to pay transaction costs and for general corporate purposes.
 
    Delano Group Securities LLC and Mr. David Valentine acted as advisors on the transaction. The Company paid Delano Group Securities LLC $16,250 and 476 shares of common stock and Mr. Valentine 476 shares of common stock for their services. Mr. Asplund and Mr. Valentine both were serving as directors of Lime Energy at that time. Subsequently, on January 23, 2006, Mr. Asplund became the Company’s CEO.
 
d)   On May 3, 2005 the Company issued 23,735 shares of common stock in connection with the acquisition of Maximum Performance Group, Inc. Please refer to Note 4 for additional information regarding this transaction.

Notes to Consolidated Financial Statements
    Delano Group Securities LLC acted as an advisor on the acquisition of MPG and was paid $82,176 and 1,195 shares of common stock for its services. These shares were valued at $105.00 per share, which was the closing market price of the Company’s common stock on April 28, 2005. Delano Group Securities LLC is owned by Mr. David Asplund, one of Lime Energy’s directors and effective January 23, 2006, its CEO.
 
e)   On November 22, 2005 the Company entered into a securities purchase agreement with Laurus Master Fund, Ltd. whereby the Company issued to Laurus a $5 million secured convertible term note and warrants to purchase 19,048 shares of its common stock at $121.80 per share anytime prior to November 22, 2012. The warrants were valued at $920,000 using a modified Black-Scholes option pricing model utilizing the following assumptions: risk free rate of 4.034%; expected volatility of 67.4%; expected dividend of $0; and expected life of 7 years. The value of the warrants was recorded as a discount to the term loan and was to be amortized over the term of the underlying debt utilizing the effective interest method.
 
    This term loan was retired through a cash payment on June 29, 2006. No portion of the term loan was converted to common stock.
 
f)   During the year ended December 31, 2005, the Company’s Board of Directors declared dividends payable on its Series E Convertible Preferred Stock of $1,366,900. The dividends were paid with 13,699 additional shares of Series E Convertible Preferred Stock.
2006 Transactions
g)   In January 2006 the Company issued stock options at the then current market price of $65.10 per share, which was less than the $96.60 exercise price on a warrant held by one of its former Series E Preferred stock holders. Adjusting the exercise price of this warrant resulted in a non-cash deemed dividend of $266,390.
 
h)   During the first three months of 2006, two holders of the Company’s Series E Convertible Preferred Stock converted a total of 7,130 shares of Series E Convertible Preferred Stock into 6,790 shares of common stock.
 
i)   Effective March 31, 2006, the Company received 2,027 shares of its common stock as part of the sale of its Great Lakes Controlled Energy Corporation subsidiary to Messrs. Eugene Borucki and Denis Enberg. These shares have been returned to the status of authorized, unissued shares of common stock.
 
j)   A number of the Company’s common stock warrants contain anti-dilution provisions that automatically adjust the exercise price on the warrants to the issuance price of any security convertible into the Company’s common stock if the price of the newly issued security is less than the exercise price on the holder’s warrant. Prior to the PIPE Transaction described in i) above, the exercise price on these warrants ranged from $94.50 per share to $105.00 per share. The issuance of common stock in the PIPE Transaction caused the exercise price on these warrants to automatically be reduced to $7.00 per share. Utilizing a modified Black-Scholes option pricing model, the Company determined that the increase in value of these warrants that resulted from this adjustment was $297,868, which the Company recorded as a non-cash deemed dividend on June 29, 2006. The

    Company used the following assumptions when determining the change in value of these warrants: risk free rate of 5.036%; expected volatility of between 97.8% and 154.7; expected dividend of $0; and expected lives of between 0.4 years and 2.7 years.
 
k)   Immediately following completion of the PIPE Transaction described in Note 20 above, and prepayment of the Laurus term loans, Laurus elected to convert the entire outstanding balance on its revolving line of credit, along with accrued interest thereon, into 135,838 shares of the Company’s common stock. In addition, in consideration of the issuance of 56,085 shares of common stock, Laurus agreed to (i) waive the payment of liquidated damages due as a result of the Company’s failure to register shares of common stock into which the November 2005 $5 million term loan was convertible, and (ii) terminate the requirement that the Company pay it a portion of the cash flows generated by VNPP projects for a period of 5 years following the repayment of the November 2005 $5 million convertible term loan.
 
l)   On June 30, 2006, the Company issued 714,286 shares to the Parke Family Trust as part of the consideration in the acquisition of Parke P.A.N.D.A. Corporation. Please refer to Note 4 for additional information regarding this transaction.
 
m)   During the first six months of 2006, the Company’s Board of Directors declared dividends payable on the Company’s Series E Convertible Preferred Stock of $698,000. The dividends were paid with 6,980 additional shares of Series E Convertible Preferred Stock.
 
n)   On July 25, 2006, the Company issued a three year warrant to purchase 8,571 shares of its common stock at $7.00 per share to Bristol Capital, Ltd. This warrant was valued at $25,200 using a modified Black-Scholes option pricing model utilizing the following assumptions: risk free rate of 5.108%; expected volatility of 91.4%; expected dividend of $0; and expected life of 3 years. The value of this warrant was charged to operations during the period.
 
o)   On September 26, 2006, the Company issued 71,429 shares of its common stock to Pradeep and Susan Kapadia as part of the consideration in the acquisition of Kapadia Consulting, Inc. Please refer to Note 4 for additional information regarding this transaction.
2007 Transactions
p)   In January 2007, pursuant to the Directors’ Option Plan the Company granted options to certain outside directors with an exercise price of $6.30 per share, which was the market price on the date of issuance. Warrants held by 12 investors, including Messrs. Asplund and Kiphart, contained anti-dilution provisions that automatically adjust the exercise price on the warrants to the issuance price of any security convertible into the Company’s common stock if the price of the newly issued security is less than the exercise price on the holder’s warrant. Prior to granting of the director options, the exercise price on these warrants was $7.00 per share. The grant of the director options caused the exercise price on these warrants to automatically be reduced to $6.30 per share. Utilizing a modified Black-Scholes option pricing model, the Company determined that the increase in value of these warrants that resulted from this adjustment was $19,204, which the Company recorded as an expense in January 2007. The Company used the following assumptions when determining the change in value of these warrants: risk free rate of 5.026%; expected volatility of between 73.5% and 127.7; expected dividend of $0; and expected lives of between 0.5 years and 1.7 years.

q)   During January 2007, the Company issued consultants warrants with terms of two to three years to purchase 38,571 shares of its common stock at prices of $7.00 to $7.56 per share as partial consideration for services provided the Company. These warrants were valued at $162,000 using a modified Black-Scholes option pricing model utilizing the following assumptions: risk free rate of 5.129%; expected volatility of 88.9%; expected dividend of $0; and expected life of two to three years. The value of the warrants was charged to operations during 2007.
 
r)   A provision of the June 2006 PIPE transaction required the Company to file and have declared effective by no later than November 3, 2006, a registration statement registering the shares issued as part of the transaction. To the extent that it failed to have the registration statement declared effective by this date, it was required to pay penalties to the PIPE investors at the rate of 1% per month of the purchase price paid by the investors. Largely as a result of the questions regarding the need to amend its Certificate of Incorporation to effect the 2006 reverse split of its stock, the Company was not able to have the registration statement declared effective until February 14, 2007. All of the investors in the PIPE transaction agreed to accept shares of the Company’s common stock as payment of this registration penalty. As of December 31, 2006, the Company had accrued $345,583 in penalties related to its failure to register these shares. The accrued penalties, along with $268,125 of penalties for the period from January 1, 2007 through February 14, 2007, were satisfied through the issuance of 87,673 shares of common stock in January and February 2007.
 
s)   On February 23, 2007, the Company commenced a rights offering to stockholders in which it distributed to each holder of record as of February 23, 2007 (other than the former Series E Preferred stockholders and Daniel Parke, who waived their rights to participate), non-transferable subscription rights to purchase shares of the Company’s common stock at $7.00 per share. Stockholders that participated in the rights offering were also able to subscribe for any shares that were not purchased by other stockholders pursuant to their subscription rights. The rights offering closed on March 30, 2007 and raised $2,796,700 (net of issuance costs of $202,932) through the issuance of 428,519 shares of common stock to 260 of the Company’s existing stockholders. The Company received the proceeds from the offering and issued the common stock to the participants during the first week of April 2007.
 
t)   In connection with the placement of the subordinated convertible term notes during the second quarter of 2007 the Company issued four-year warrants to eight investors, including Richard Kiphart, the Company’s chairman and largest individual stockholder, to purchase 206,043 shares of its common stock at $7.28 per share. These warrants were valued at $1,136,537 using a modified-Black Scholes option pricing model utilizing the following assumptions: risk free rate of 4.846%; expected volatility of 93.3%; expected dividend of $0; and expected life of four years. The value of the warrants was recorded as a discount to the subordinated convertible term notes and will be amortized over the life of the notes using the effective interest method.

u)   As part of the MPG acquisition, 23,735 shares of common stock were deposited in escrow for the benefit of the selling stockholders of MPG to be released over the two-year period following the April 30, 2005 purchase of MPG if it achieved certain revenue targets during the period. During May 2007 the Company issued 2,818 shares to the former MPG stockholders which it determined it owed them pursuant to the MPG merger agreement. These shares were valued at $8.89 per share, the market value on the date of their release, and recorded as an increase in the goodwill associated with the MPG acquisition. The remaining 20,917 shares that were in escrow were returned to the Company and retired and became authorized but un-issued shares.
 
v)   Delano Group Securities LLC acted as an advisor on the acquisition of MPG in 2005. Part of Delano’s compensation for its services was tied to the purchase price paid for MPG. Mr. David Asplund owned and operated Delano prior to joining Lime Energy as its CEO in January 2006. Since the release of the escrow shares was considered a payment of additional consideration to the former stockholders of MPG, the Company issued Mr. Asplund 141 shares of its common stock in May 2007 in satisfaction of the commission owed Delano. These shares were valued at $1,252, based on the market value on the date of their issuance, and recorded as an increase in the goodwill associated with the MPG acquisition.
 
w)   On June 6, 2007, retroactive to May 31, 2007, the Company acquired the assets and assumed certain liabilities of George Bradley Boyett dba Texas Energy Products. The purchase consideration consisted of 28,571 shares of Lime Energy common stock and cash of $312,787. For accounting purposes the stock was valued at $7.49 per share, the average closing price of the stock for the 20 trading days immediately prior to the closing. Please refer to Note 4 for additional information regarding this transaction.
 
x)   On August 6, 2007, retroactive to July 31, 2007, the Company acquired the assets and assumed certain liabilities of Preferred Lighting, Inc. for 15,069 shares of Lime Energy common stock and cash of $409,953 (including $109,953 paid in 2008 pursuant to an earn-out based on 2007 earnings). The company also issued five year warrants to the former owners of Preferred Lighting to purchase 21,429 shares of the Company’s common stock at $13.23 per share. These warrants were valued at $184,500 using a modified-Black Scholes option pricing model utilizing the following assumptions: risk free rate of 4.909%; expected volatility of 75.0%; expected dividend of $0; and expected life of four years. The value of the warrants were considered part of the purchase consideration. Please refer to Note 4 for additional information regarding this transaction.
 
y)   During 2007, the Company issued 7,088 shares of its common stock to the holders of its subordinated convertible term notes in satisfaction of 50% of the interest owed on the note.
 
z)   During 2007 certain employees and a former director exercised options to purchase 33,005 shares of the Company’s common stock as exercise prices ranging from $6.30 to $7.14 per share.
 
aa)   During 2007 six investors exercised their warrants to purchase 5,011 shares of the Company’s common stock at $6.30 per share. One of these investors elected to exercise its warrant on a cashless basis, surrendering 569 shares it would have otherwise be entitled to receive on exercise to cover the exercise price.

Note 24 — Reverse Splits
     On June 15, 2006, the Company effected a 1 for 15 reverse split of its common stock. A second reverse split of the Company’s common stock was effected on January 25, 2007, this one on a 1 for 7 basis. All share amounts stated herein have been retroactively restated to reflect these reverse splits.
Note 25 — Stock Options
     On August 30, 2001, the Company’s shareholders approved the adoption of the 2001 Stock Incentive Plan (the “Plan”), providing that up to 7,619 shares of the Company’s common stock could be delivered under the Plan to certain employees of the Company or any of its subsidiaries and to consultants and directors who are not employees. In addition, the Plan originally provided for an additional number of shares of the Company’s common stock to be reserved for issuance under the plan on January 1st of each succeeding year, beginning January 1, 2002, in an amount equal to the lesser of (i) 5% of the number of outstanding shares of Common Stock, or (ii) 4,762 shares. At the annual meeting held on June 7, 2006, the Company’s stockholders approved an amendment to the Plan which increased the number of shares reserved for issuance under the plan by 57,143 shares and increased the additional shares which would become automatically available under the plan each January 1st to the lesser of (i) 5% of the number of outstanding shares of Common Stock, or (ii) 19,048 shares. The awards granted under the Plan may be incentive stock options or non-qualified stock options. The exercise price for any incentive stock option (“ISO”) may not be less than 100% of the fair market value of the stock on the date the option is granted, except that with respect to a participant who owns more than 10% of the common stock the exercise price must be not less than 110% of fair market value. The exercise price of any non-qualified option shall be in the sole discretion of the Compensation Committee or the Board. To qualify as an ISO the aggregate fair market value of the shares (determined on the grant date) under options granted to any participant may not exceed $100,000 in the first year that they can be exercised. There is no comparable limitation with respect to non-qualified stock options. The term of all options granted under the Plan will be determined by the Compensation Committee or the Board in their sole discretion, provided, however, that the term of each ISO shall not exceed 10 years from the date of grant thereof.
     In addition to the ISOs and non-qualified options, the Plan permits the Compensation Committee, consistent with the purposes of the Plan, to grant stock appreciation rights and/or shares of Common Stock to non-employee directors and such employees (including officers and directors who are employees) of, or consultants to, the Company or any of its Subsidiaries, as the Committee may determine, in its sole discretion. Under applicable tax laws, however, ISO’s may only be granted to employees.
     The Plan is administered by the Board, which is authorized to interpret the Plan, to prescribe, amend and rescind rules and regulations relating to the Plan and to determine the individuals to whom, and the time, terms and conditions under which, options and awards are granted. The Board may also amend, suspend or terminate the Plan in any respect at any time. However, no amendment may (i) adversely affect the rights of a participant under an award theretofore granted without the consent of such participant, (ii) increase the number of shares reserved under the Plan, (iii) modify the requirements for participation in the Plan, or (iv) modify the Plan in any way that would require stockholder approval under the rules and regulations under the Exchange Act or the rules of any stock exchange or market on which the Common Stock is listed (unless such stockholder approval is obtained).

     As of December 31, 2007, there were approximately 107 employees of the Company eligible to participate in the Plan, and 107,620 shares of common stock reserved under the Plan.
     Effective April 1, 2000, the Company adopted a stock option plan for all independent directors, which is separate and distinct from the 2001 Stock Incentive Plan described above. The plan was amended on July 11, 2006 to provide that eligible directors receive an initial option grant upon being appointed to the Company’s Board of Directors to purchase 14,286 shares of its common stock, and a grant of options to purchase an additional 7,143 shares on the first day of January beginning on the second January following the date the Director became an eligible director. These options have an exercise price equal to the closing price of the Company’s common stock on the grant date and a term of ten years. The initial options vest on the first day of January following the initial grant date or six months following the initial grant date, whichever is later, if the individual is still a director on the vesting date. All future grants vest in two equal amounts, one amount on the grant date and the balance on the anniversary of the grant date, if the individual is still a member of the Board of Directors on such anniversary date.
     During 2005, certain directors, officers and key employees of the Company were granted options to acquire 9,976 shares of common stock at exercise prices ranging from $105.00 to $130.20 per share. These options vest over periods through October 2007.

     The weighted-average, grant-date fair value of stock options granted to employees during the year, and the weighted-average significant assumptions used to determine those fair values, using a modified Black-Scholes option pricing model for stock options under Statement of Financial Accounting Standards No. 123, are as follows:
                         
Year ended December 31,   2007     2006     2005  
 
 
                       
Weighted average fair value per options granted
  $ 8.12     $ 7.35     $ 4.76  
 
                       
Significant assumptions (weighted average):
                       
Risk-free interest rate at grant date
    4.06 %     5.02 %     2.27 %
Expected stock price volatility
    88 %     90 %     65 %
Expected dividend payout
                 
Expected option life (years)
    6.1       5.6       9.1  
 
     The risk-free interest rate is based on the U.S. Treasury Bill rates at the time of grant. The dividend reflects the fact that the Company has never paid a dividend on its common stock and does not expect to in the foreseeable future. The Company estimated the volatility of its common stock at the date of grant based on the historical volatility of its stock. The expected term of the options is based on the simplified method as described in the Staff Accounting Bulletin. The Company assumes a forfeiture rate of approximate 1% based on historical experience in the calculation of share based compensation.
     The Company recognized $3,726,731, $4,828,955 and $0 of share based compensation expense related to stock options during 2007, 2006 and 2005, respectively. The following table summarizes the expense for 2007 and 2006:

     The Company recognizes compensation expense for stock options on a straight-line basis over the requisite service period, which is generally equal to the vesting period of the option. The subject stock options expire ten years after the date of grant.

     During January 2006, the Company entered into a consulting agreement with Parke P.A.N.D.A. Corporation to provide sales and marketing consulting services. Parke P.A.N.D.A. was a company which at the time was beneficially owned by Daniel Parke, one of the Company’s directors. Pursuant to the consulting agreement the Company agreed to pay Parke P.A.N.D.A. $10,000 per month and to reimburse it for any expenses incurred as a result of its work. The Company paid Parke P.A.N.D.A. a total of $61,155 during the six months ended June 30, 2006. This agreement was terminated in May 2006.
     On June 29, 2006, the Company acquired Parke P.A.N.D.A. Corporation, a company owned by The Parke Family Trust, which is controlled and beneficially owned by Daniel Parke, one of the Company’s directors, and his spouse. Please see Note 4 for additional information regarding this transaction.
     As part of the acquisition of Parke P.A.N.D.A. Corporation, the Company assumed Parke P.A.N.D.A.’s existing office lease for space in a building in Glendora California owned by a company controlled by Daniel Parke. The Company believes that the terms of the lease are fair as they are comparable to the terms of leases with other third party tenants located in the building. See Note 17 for additional information regarding this lease.
     Certain other related party transactions are disclosed in Notes 12, 17 and 29.
     The Company does not have a written policy concerning transactions between the Company or a subsidiary of the Company and any director or executive officer, nominee for director, 5% stockholder or member of the immediate family of any such person. However, the Company’s practice is that such transactions shall be reviewed by the Company’s Board of Directors and found to be fair to the Company prior to the Company (or a subsidiary) entering into any such transaction, except for (i) executive officers’ participation in employee benefits which are available to all employees generally; (ii) transactions involving routine goods or services which are purchased or sold by the Company (or a subsidiary) on the same terms as are generally available in arm’s length transactions with unrelated parties (however, such transactions are still subject to approval by an authorized representative of the Company (or a subsidiary) in accordance with internal policies and procedures applicable to such transactions with unrelated third parties); and (iii) compensation decisions with respect to executive officers other than the CEO, which are made by the Compensation Committee pursuant to recommendations of the CEO.
