Part I

Item 1. 	Description of Business



General



Hudson Technologies, Inc., incorporated under the laws of New York on January 11, 1991, is a refrigerant services company providing innovative solutions to recurring problems within the refrigeration industry.  The Company's products and services are primarily used in commercial air conditioning, industrial processing and refrigeration systems, including (i) refrigerant sales, (ii) RefrigerantSide® Services performed at a customer's site, consisting of system decontamination to remove moisture, oils and other contaminants and (iii) refrigerant management services consisting primarily of reclamation of refrigerants.  The Company operates through its wholly-owned subsidiary, Hudson Technologies Company.  Unless the context requires otherwise, references to the "Company", "Hudson", "we", "us", "our", or similar pronouns refer to Hudson Technologies, Inc. and its subsidiaries.



The Company's executive offices are located at 275 North Middletown Road, Pearl River, New York and its telephone number is (845) 735-6000.



Industry background



The production and use, in the United States, of refrigerants containing hydrochlorofluorocarbons ("HCFCs"), the most commonly used refrigerants, and chlorofluorocarbons ("CFCs") are subject to extensive and changing regulation under the Clean Air Act (the "Act").  The Act, which was amended during 1990 in response to evidence linking the use of CFCs and damage to the earth's ozone layer, prohibits any person in the course of maintaining, servicing, repairing and disposing of air conditioning or refrigeration equipment, to knowingly vent or otherwise release or dispose of ozone depleting substances used as refrigerants.  That prohibition also applies to substitute, non-ozone depleting refrigerants.  The Act also requires the recovery of refrigerants used in residential, commercial and industrial air conditioning and refrigeration systems, and, effective January 1, 1996, prohibited production of CFC refrigerants and limited the production of HCFC refrigerants.  Additionally, effective January 2004, the Act further limited the production of HCFC refrigerants, and federal regulations were enacted which impose limitations on the importation of certain virgin HCFC refrigerants.  Under the Act, production of certain HCFC refrigerants is scheduled to be phased out by the year 2020, and production of all HCFC refrigerants is scheduled to be phased out by 2030.  Under the Act, owners, operators and companies servicing cooling equipment are responsible for the integrity of the systems, regardless of the refrigerant being used, and for the responsible management of refrigerant.



Products and Services



From its inception, the Company has sold refrigerants, and has provided refrigerant reclamation and management services that are designed to preserve refrigerants, thereby protecting the environment from ozone depletion.  In addition, the reclamation process allows the refrigerant to be re-used thereby eliminating the need to destroy or manufacture additional refrigerant and eliminating the corresponding impact to the environment associated with the destruction and manufacturing.  Today, these offerings represent most of the Company's revenues.  For the past several years, the Company has created alternative solutions to reactive and preventative maintenance procedures that are performed on commercial and industrial refrigeration systems.  These services, known as RefrigerantSide® Services, compliment the Company's refrigerant sales and refrigerant reclamation and management services.  In addition, the Company has developed Performance Optimization services that identify inefficiencies in the operation of air conditioning and refrigeration systems and assists companies to improve the efficiency of their systems and save energy.  The Company believes that it's RefrigerantSide® Services, including Performance Optimization services, represent the Company's long term growth potential.  Each of the Company's products and services are more fully described below.



RefrigerantSide® Services



The Company provides decontamination and recovery services that are performed at a customer's site through the use of portable, high volume, high-speed proprietary equipment, including its patented Zugibeast® system.  Certain of these RefrigerantSide® Services, which encompass system decontamination, and refrigerant recovery and reclamation are also proprietary and are covered by process patents.



In addition to the decontamination and recovery services previously described, the Company also provides predictive and diagnostic services for its customers.  The Company offers diagnostic services that are intended to predict potential problems in air conditioning and refrigeration systems before they occur.  The Company's Chiller Chemistry® offering integrates several fluid tests of an operating system and the corresponding laboratory results into an engineering report providing its customers with an understanding of the current condition of the fluids, the cause for any abnormal findings and the potential consequences if the abnormal findings are not remediated.  ChillSmart® combines the diagnostic information of Chiller Chemistry® with a detailed performance evaluation for an operating refrigeration system and recommendations for eliminating any inefficiencies that may have been discovered.



In 2003, the Company was awarded an United States patent for its Performance Optimization System, which is a system for measuring, modifying and improving the efficiency of energy systems, including air conditioning and refrigeration systems, in industrial and commercial applications.  Hudson's Performance Optimization Services are able to identify specific inefficiencies in the operation of refrigeration systems and, when used with Hudson's RefrigerantSide® Services, can increase the efficiency of the operating systems thereby reducing energy usage and costs.  These inefficiencies require power generating companies to produce more energy and, in many instances increase CO2 emissions to produce the excess energy.  Consequently, not only is Hudson's reclamation system beneficial to the environment, but Hudson's Performance Optimization Services recommendations are also designed to achieve an overall reduction in CO2 emissions.  The Company's Performance Optimization Services have allowed the Company to become an Energy Star® Service and Product Provider Partner.  The Company's Performance Optimization System can be customized to a particular customer's refrigeration system, such as at an industrial facility that utilizes refrigeration in its manufacturing processes, or offered as a stand alone product that can be used with air conditioning and packaged refrigeration systems, such as a comfort cooling application in large office buildings.  When the Company combines it Performance Optimization System with its Chiller Chemistry® the Company calls this combined offering ChillSmart®.



Refrigerant Sales



The Company sells reclaimed and virgin (new) refrigerants to a variety of customers in various segments of the air conditioning and refrigeration industry.  Virgin, non-CFC refrigerants, including HCFC refrigerants, are purchased by the Company from several suppliers and resold by the Company, typically at wholesale.  The Company continues to sell reclaimed CFC based refrigerants, which are no longer manufactured.  The Company regularly purchases used or contaminated refrigerants, some of which are CFC based, from many different sources, which refrigerants are then reclaimed using the Company's high volume proprietary reclamation equipment, the Zugibeast® system, and resold by the Company.



Refrigerant Management Services



The Company provides a complete offering of refrigerant management services, which primarily include reclamation of refrigerants, laboratory testing, through the Company's Air Conditioning and Refrigeration Institute ("ARI") certified lab, and banking (storage) services tailored to individual customer requirements.  Hudson also separates "crossed" (i.e. commingled) refrigerants and provides re-usable cylinder repair and hydrostatic testing services.



Hudson's Network



Hudson operates from a network of facilities located in:

|Pearl River, New York     | --Company headquarters and administrative offices                                                               
|Pottsboro, Texas          | --Telemarketing office                                                                                          
|Raymond, New Hampshire    | --Telemarketing office                                                                                          



Strategic Alliances



In January 1997, the Company entered into an agreement with E.I. DuPont de Nemours and Company ("DuPont"), pursuant to which the Company provides recovery, reclamation, separation, packaging and testing services directly to DuPont for marketing through DuPont's distributor network.  The agreement expires February 28, 2008 and is subject to earlier termination, as defined in the agreement, by either party.



The Company's sales and marketing efforts for RefrigerantSide® Services business is focused on customers that the Company believes most readily appreciate and understand the value that is provided by its RefrigerantSide® Service offering.  Moreover, to maintain its current ability to quickly respond to customer service requests throughout the United States, the Company seeks to pursue the creation of strategic alliances with companies that service larger industrial customers in targeted industries, which, when consummated, would enable the Company to (i) co-locate its equipment with these strategic partners and (ii) utilize these partners' sales and marketing resources to offer their customers the Company's RefrigerantSide® Services.



The Company believes that the international market for refrigerant reclamation, sales and services is equal in size to the United States market for those sales and services.  In furtherance of the Company's efforts to expand its presence outside the United States, in June 2003 the Company entered into an exclusive global technology and marketing agreement with The Linde Group ("Linde"), formerly

the BOC Group, a worldwide industrial gases, vacuum technologies and distribution services company that serves two million customers in more than 50 countries.  Under the agreement, the Company has licensed its RefrigerantSide® Services technology to Linde, and the Company has agreed to enter into separate supplemental agreements with certain Linde affiliate companies, pursuant to which the Company will license its RefrigerantSide® Services technology and the use of its related proprietary equipment to each Linde affiliate in return for a license fee payable to the Company by the Linde affiliate in annual installments during the course of that supplemental agreement and royalty payments to the Company based on revenues derived by the Linde affiliate from the performance of RefrigerantSide® Services and other sales licensed from the Company.  The arrangement is specifically aimed at marketing and developing the Company's RefrigerantSide® and other performance optimization services in over 20 countries outside the United States.  Currently, the Company has executed two separate supplemental agreements with Linde affiliates covering the United Kingdom and the Republic of South Africa.  The agreement with Linde is, and each supplemental agreement with a Linde affiliate will be, for an initial term of seven years and may be further extended for an initial period of three years and thereafter on an open-ended basis unless earlier terminated.



Suppliers



The Company's financial performance and its ability to sell refrigerants is in part dependent on its ability to obtain sufficient quantities of virgin, non-CFC based refrigerants, and of reclaimable, primarily CFC based, refrigerants from manufacturers, from wholesalers, distributors, bulk gas brokers and from other sources within the air conditioning, refrigeration and automotive aftermarket industries, and on corresponding demand for refrigerants.  The Company's refrigerant sales include CFC based refrigerants, which are no longer manufactured.  Additionally, the Company's refrigerant sales include non-CFC based refrigerants, including HCFC refrigerants.  Effective January 1, 1996, the Act limits the production of HCFC refrigerants, which production was further limited in January 2004.  Federal regulations enacted in January 2004 also imposed limitations on the importation of certain HCFC refrigerants.  Under the Act, the production of certain HCFC refrigerants is scheduled to be phased out by the year 2020 and production of all HCFC refrigerants is scheduled to be phased out by the year 2030.  Notwithstanding the limitations imposed by and under the Act, the Company believes that sufficient quantities of new and used refrigerants will continue to be available to it at a reasonable cost for the foreseeable future.  To the extent the Company is unable to source sufficient quantities of virgin or reclaimable refrigerants in the future, or resell refrigerants at a profit, the Company's financial condition and results of operations would be materially adversely affected.



Customers



The Company provides its services to commercial, industrial and governmental customers, as well as to refrigerant wholesalers, distributors, contractors and to refrigeration equipment manufacturers.  Agreements with larger customers generally provide for standardized pricing for specified services.



For the year ended December 31, 2006, one customer accounted for 10% of the Company's revenues.  For the year ended December 31, 2005, one customer accounted for 13%, and one customer accounted for 11% of the Company's revenues.



Marketing



Marketing programs are conducted through the efforts of the Company's executive officers, Company sales personnel, and third parties.  Hudson employs various marketing methods, including direct mailings, technical bulletins, in-person solicitation, print advertising, response to quotation requests and the internet www.hudsontech.com.  Information in the Company's website is not part of this report.



The Company's sales personnel are compensated on a combination of a base salary and commission.  The Company's executive officers devote significant time and effort to customer relationships.



Competition



The Company competes primarily on the basis of the performance of its proprietary high volume, high-speed equipment used in its operations, the breadth of services offered by the Company, including proprietary RefrigerantSide® Services and other on-site services, and price, particularly with respect to refrigerant sales.



The Company competes with numerous regional and national companies that market reclaimed and virgin refrigerants and provide refrigerant reclamation services.  Certain of these competitors possess greater financial, marketing, distribution and other resources for the sale and distribution of refrigerants than the Company and, in some instances, serve a more extensive geographic area than the Company.



Hudson's RefrigerantSide® Services provide new and innovative solutions to certain problems within the refrigeration industry and, as such, the demand and market acceptance for these services are subject to uncertainty.  Competition for these services primarily consists of traditional methods of solving the industry's problems.  The Company's marketing strategy is to educate the market place

that its alternative solutions are available and that RefrigerantSide® Services are superior to traditional methods.  The market acceptance for these services is subject to uncertainty.



Insurance



The Company carries insurance coverage that it considers sufficient to protect the Company's assets and operations.  The Company currently maintains general commercial liability insurance and excess liability coverage for claims up to $7,000,000 per occurrence and $8,000,000 in the aggregate.  The Company attempts to operate in a professional and prudent manner and to reduce potential liability risks through specific risk management efforts, including ongoing employee training.



The refrigerant industry involves potentially significant risks of statutory and common law liability for environmental damage and personal injury.  The Company, and in certain instances, its officers, directors and employees, may be subject to claims arising from the Company's on-site or off-site services, including the improper release, spillage, misuse or mishandling of refrigerants classified as hazardous or non-hazardous substances or materials.  The Company may be held strictly liable for damages, which could be substantial, regardless of whether it exercised due care and complied with all relevant laws and regulations.



Hudson maintains environmental impairment insurance of $1,000,000 per occurrence, and $2,000,000 annual aggregate, for events occurring subsequent to November 1996.



Government Regulation



The business of refrigerant sales, reclamation and management is subject to extensive, stringent and frequently changing federal, state and local laws and substantial regulation under these laws by governmental agencies, including the United States Environmental Protection Agency ("EPA"), the United States Occupational Safety and Health Administration and the United States Department of Transportation.



Among other things, these regulatory authorities impose requirements which regulate the handling, packaging, labeling, transportation and disposal of hazardous and non-hazardous materials and the health and safety of workers, and require the Company and, in certain instances, its employees, to obtain and maintain licenses in connection with its operations.  This extensive regulatory framework imposes significant compliance burdens and risks on the Company.



Hudson and its customers are subject to the requirements of the Act, and the regulations promulgated thereunder by the EPA, which make it unlawful for any person in the course of maintaining, servicing, repairing, and disposing of air conditioning or refrigeration equipment, to knowingly vent or otherwise release or dispose of ozone depleting substances, and non-ozone depleting substitutes, used as refrigerants.



Pursuant to the Act, reclaimed refrigerant must satisfy the same purity standards as newly manufactured refrigerants in accordance with standards established by the ARI prior to resale to a person other than the owner of the equipment from which it was recovered.  The EPA administers a certification program pursuant to which applicants certify to reclaim refrigerants in compliance with ARI standards.  In February 2006, the Company became one of only three certified refrigerant testing certified laboratories under ARI's laboratory certification program, which is a voluntary program that certifies the ability of a laboratory to test refrigerant in accordance with the ARI 700 standard.



In addition, the EPA has established a mandatory certification program for air conditioning and refrigeration technicians.  Hudson's technicians have applied for or obtained such certification.



The Company is also subject to regulations adopted by the United States Department of Transportation which classify most refrigerants handled by the Company as hazardous materials or substances and impose requirements for handling, packaging, labeling and transporting refrigerants and which regulate the use and operation of the Company's commercial motor vehicles used in the Company's business.



The Resource Conservation and Recovery Act of 1976 ("RCRA") requires facilities that treat, store or dispose of hazardous wastes to comply with certain operating standards.  Before transportation and disposal of hazardous wastes off-site, generators of such waste must package and label their shipments consistent with detailed regulations and prepare a manifest identifying the material and stating its destination.  The transporter must deliver the hazardous waste in accordance with the manifest to a facility with an appropriate RCRA permit.  Under RCRA, impurities removed from refrigerants consisting of oils mixed with water and other contaminants are not presumed to be hazardous waste.



The Emergency Planning and Community Right-to-Know Act of 1986 requires the annual reporting by the Company of Emergency and Hazardous Chemical Inventories (Tier II reports) to the various states in which the Company operates and requires the Company to file annual Toxic Chemical Release Inventory Forms with the EPA.



The Comprehensive Environmental Response, Compensation and Liability Act of 1980 ("CERCLA"), establishes liability for clean-up costs and environmental damages to current and former facility owners and operators, as well as persons who transport or arrange for transportation of hazardous substances.  Almost all states have similar statutes regulating the handling and storage of hazardous substances, hazardous wastes and non-hazardous wastes.  Many such statutes impose requirements that are more stringent than their federal counterparts.  The Company could be subject to substantial liability under these statutes to private parties and government entities, in some instances without any fault, for fines, remediation costs and environmental damage, as a result of the mishandling, release, or existence of any hazardous substances at any of its facilities.



The Occupational Safety and Health Act of 1970 mandates requirements for a safe work place for employees and special procedures and measures for the handling of certain hazardous and toxic substances.  State laws, in certain circumstances, mandate additional measures for facilities handling specified materials.



The Company believes that it is in compliance with all material regulations relating to its material business operations.



Quality Assurance & Environmental Compliance



The Company utilizes in-house quality and regulatory compliance control procedures.  Hudson maintains its own analytical testing laboratory, which is ARI certified, to assure that reclaimed refrigerants comply with ARI purity standards and employs portable testing equipment when performing on-site services to verify certain quality specifications.  The Company employs four persons engaged full-time in quality control and to monitor the Company's operations for regulatory compliance.



Employees



The Company has 65 full and 7 part time employees including air conditioning and refrigeration technicians, chemists, engineers, sales and administrative personnel.



None of the Company's employees are represented by a union.  The Company believes that its employee relations are good.



Patents and Proprietary Information



The Company holds an United States patent, and holds eight foreign patents covering seventeen foreign countries and patent applications pending in two other foreign countries, relating to the high-speed equipment, components and process to reclaim refrigerants, and a registered trademark for its Zugibeast®.  The United States patent expires in January 2012 and the foreign patents will expire between May 2014 and December 2014.  The Company also holds several US and foreign patents related to certain RefrigerantSide® Services developed by the Company as well as for certain processes to measure and improve the efficiency of refrigeration systems.  These patents will expire between February 2017 and December 2020.



The Company believes that patent protection is important to its business.  There can be no assurance as to the breadth or degree of protection that patents may afford the Company, that any patent applications will result in issued patents or that patents will not be circumvented or invalidated.  Technological development in the refrigerant industry may result in extensive patent filings and a rapid rate of issuance of new patents.  Although the Company believes that its existing patents and the Company's equipment do not and will not infringe upon existing patents or violate proprietary rights of others, it is possible that the Company's existing patent rights may not be valid or that infringement of existing or future patents or violations of proprietary rights of others may occur.  In the event the Company's equipment or processes infringe, or are alleged to infringe, patents or other proprietary rights of others, the Company may be required to modify the design of its equipment or processes, obtain a license or defend a possible patent infringement action.  There can be no assurance that the Company will have the financial or other resources necessary to enforce or defend a patent infringement or proprietary rights violation action or that the Company will not become liable for damages.



The Company also relies on trade secrets and proprietary know-how, and employs various methods to protect its technology.  However, such methods may not afford complete protection and there can be no assurance that others will not independently develop such know-how or obtain access to the Company's know-how, concepts, ideas and documentation.  Failure to protect its trade secrets could have a material adverse effect on the Company.



Business Risk Factors



There are many important factors that have affected, and in the future could affect the Company's business including, but not limited to, the factors discussed below, which should be reviewed carefully together with the other information contained in this report.  Some of the factors are beyond the Company's control and future trends are difficult to predict.



The Company may need additional financing to satisfy its future capital requirements, which may not be readily available to the Company.



The Company's capital requirements have been and may be significant in the future.  In the future, the Company may incur additional expenses in the development and implementation of its operations.  As a result, the Company may be required to seek additional equity or debt financing in order to develop its RefrigerantSide® Services business and other businesses.  The Company has no current arrangements with respect to, or sources of, additional financing other than a bank line of credit that expires in May 2008.  If additional financing is available, it may not be available on acceptable terms.  The Company's inability to obtain additional capital financing, if and when needed, could materially adversely affect its business and future financial condition and could require the Company to curtail or otherwise cease its existing operations.



The nature of the Company's business exposes it to potential liability.



The refrigerant recovery and reclamation industry involves potentially significant risks of statutory and common law liability for environmental damage and personal injury.  The Company, and in certain instances, its officers, directors and employees, may be subject to claims arising from the Company's on-site or off-site services, including the improper release, spillage, misuse or mishandling of refrigerants classified as hazardous or non-hazardous substances or materials.  The Company may be strictly liable for damages, which could be substantial, regardless of whether the Company exercised due care and complied with all relevant laws and regulations.  The Company's current insurance coverage may not be sufficient to cover potential claims, and adequate levels of insurance coverage may not be available in the future at a reasonable cost.  A partially or completely uninsured claim against the Company, if successful and of sufficient magnitude would have a material adverse effect on the Company.



The Company's business and financial condition is substantially dependent on the sale and continued environmental regulation of refrigerants.



The Company's business and prospects are largely dependent upon continued regulation of the use and disposition of refrigerants.  Changes in government regulations relating to the emission of refrigerants into the atmosphere could have a material adverse effect on the Company.  Failure by government authorities to otherwise continue to enforce existing regulations or significant relaxation of regulatory requirements could also adversely affect demand for the Company's services and products.



The Company's business is subject to significant regulatory compliance burdens.



The refrigerant reclamation and management business is subject to extensive, stringent and frequently changing federal, state and local laws and substantial regulation under these laws by governmental agencies, including the EPA, the United States Occupational Safety and Health Administration and the United States Department of Transportation.  Although the Company believes that it is in substantial compliance with all material regulations relating to its material business operations, amendments to existing statutes and regulations or adoption of new statutes and regulations which affect the marketing and sale of refrigerant could require the Company to continually alter its methods of operation and/or discontinue the sale of certain of its products resulting in costs to the Company that could be substantial.  The Company may not be able, for financial or other reasons, to comply with applicable laws, regulations and permit requirements, particularly as it seeks to enter into new geographic markets.  The Company's failure to comply with applicable laws, rules or regulations or permit requirements could subject it to civil remedies, including substantial fines, penalties and injunctions, as well as possible criminal sanctions, which would, if of significant magnitude, materially adversely impact its operations and future financial condition.



As a result of competition, and the strength of some of its competitors in the market, the Company may not be able to compete effectively.



The markets for the Company's services and products are highly competitive.  The Company competes with numerous regional and national companies which provide refrigerant recovery and reclamation services, as well as companies which market and deal in reclaimed and alternative refrigerants, including certain of its suppliers, some of which possess greater financial, marketing, personnel and other resources than the Company.  The Company also competes with numerous manufacturers of refrigerant recovery and reclamation equipment.  Certain of these competitors have established reputations for success in the service of air conditioning and refrigeration systems.  The Company may not be able to compete successfully, particularly as it seeks to enter into new markets.



A number of factors could negatively impact the price and/or availability of refrigerants, which would, in turn, adversely affect the Company's business and financial condition.



Refrigerant sales continue to represent a significant portion of the Company's revenues.  Therefore, the Company's business is substantially dependent on the availability of both new and used refrigerants in large quantities, which may be affected by several factors including commercial production and consumption limitations imposed by the Act and government regulation on HCFC refrigerants; the ban on production of CFC based refrigerants under the Act; the introduction of new refrigerants and air conditioning and refrigeration equipment; price competition resulting from additional market entrants; and changes in government regulation on the use and production of refrigerants.  The Company does not maintain firm agreements with any of its suppliers of refrigerants.  Sufficient amounts of new and/or used refrigerants may not be available to the Company in the future, or may not be available on

commercially reasonable terms.  Additionally, the Company may be subject to price fluctuations, periodic delays or shortages of new and/or used refrigerants.  The Company's failure to obtain and resell sufficient quantities of virgin refrigerants, or to obtain, reclaim and resell sufficient quantities of used refrigerants would have a material adverse effect on its operating margins and results of operations.



The loss of key management personnel would adversely impact the Company's business.



The Company's success is largely dependent upon the efforts of its Chief Executive Officer and Chairman, the loss of his services would have a material adverse effect on the Company's business and prospects.



The Company has the ability to designate and issue preferred stock, which may have rights, preferences and privileges greater than the Company's Common Stock and which could impede a subsequent change in control of Hudson.



The Company's Certificate of Incorporation authorizes its Board of Directors to issue up to 5,000,000 shares of "blank check" preferred stock and to fix the rights, preferences, privileges and restrictions, including voting rights, of these shares, without further shareholder approval.  The rights of the holders of the Company's Common Stock will be subject to, and may be adversely affected by, the rights of holders of any additional preferred stock that may be issued in the future.  The Company's ability to issue preferred stock without shareholder approval could have the effect of making it more difficult for a third party to acquire a majority of its voting stock, thereby delaying, deferring or preventing a change in control of Hudson.



If the Company's Common Stock were delisted from NASDAQ it would be subject to "penny stock" rules which could negatively impact its liquidity and the Company's stockholders' ability to sell their shares.



The Company's Common Stock is currently listed on the NASDAQ Capital Market.  The Company must comply with numerous NASDAQ MarketPlace rules in order to continue the listing of its Common Stock on NASDAQ.  There can be no assurance that the Company can continue to meet the rules required to maintain the NASDAQ listing of the Company's Common Stock.  If the Company is unable to maintain its listing on NASDAQ, the market liquidity of the Company's Common Stock may be severely limited.



The Fleming US Discovery Fund III, L.P. and the Fleming US Discovery Offshore Fund III, L.P. effectively control the affairs of the Company.



Currently, the Fleming US Discovery Fund III, L.P. and the Fleming US Discovery Offshore Fund III, L.P. ("Fleming Funds") collectively own approximately 74% of the Company's outstanding Common Stock.  Accordingly, the Flemings Funds are in a position to significantly effect, and potentially fully control the Company and the election of its directors, and generally direct the Company's affairs.  There is no provision for cumulative voting for the Company's directors.

Item 3.  Legal Proceedings



On April 1, 1999, the Company reported a release of approximately 7,800 lbs. of R-11 refrigerant (the "1999 Release"), at its leased facility in Hillburn, NY, which was vacated in June 2006 ("Facility").  A failed hose connection to one of the Company's outdoor storage tanks allowed liquid R-11 to discharge from the tank into the concrete secondary containment area in which the subject tank was located.



Between April 1999 and May 1999, with the approval of the New York State Department of Environmental Conservation ("DEC"), the Company constructed and put into operation a remediation system to remove R-11 levels in the groundwater under and around the Facility.



In September 2000, the Company signed an Order on Consent with the DEC, which was amended in May 2001, whereby the Company agreed to operate the remediation system and perform monthly testing at the Facility, until remaining groundwater contamination has been effectively abated.  In July 2005, the DEC approved a modification of the Order on Consent to reduce the frequency of testing from monthly to quarterly.  The Company is continuing to operate the remediation system pursuant to the approved modifications to that Order on Consent and, as of December 31, 2006, the Company has accrued, as an expense in its consolidated financial statements, the costs that the Company believes it will incur in connection with its compliance with the Order on Consent through December 31, 2009.  There can be no assurance that additional testing will not be required or that the Company will not incur additional costs, and such costs in excess of the Company's estimate may have a material adverse effect on the Company financial condition or results of operations.



In May 2000, the Facility, as a result of the 1999 release, was nominated by the EPA for listing on the National Priorities List ("NPL") pursuant to CERCLA.  The Company submitted opposition to the listing within the sixty-day comment period.  In September 2003, the EPA advised the Company that it has no current plans to finalize the process for listing of the Facility on the NPL and that the EPA will not withdraw the proposal for listing on the NPL.



In October 2001, the Company learned that trace levels of R-11 were detected in one of the wells operated by United Water of New York, Inc. ("United") that is in the closest proximity to the Village of Suffern's ("Village") well system.  No contamination of R-11 has ever been detected in any of the Village's wells and, since October 2002, the level of R-11 in the United well closest to the Village has been below 1 ppb.  In September 2004, the Village advised that it intends to continue performing additional sampling of its wells at a cost of approximately $5,000 per year and the Company has reimbursed the Village for sampling costs through September 2005.



The Company has exhausted all insurance proceeds available for the 1999 Release under all applicable policies.



During the year ended December 31, 2006, the Company incurred $47,000 in additional remediation costs in connection with the matters above and such amount has been included as a component of general and administrative expenses.  There can be no assurance that the 1999 Release will not impact the Village wells, or that the ultimate outcome of the 1999 Release will not have a material adverse effect on the Company's financial condition and results of operations.  There can be no assurance that the EPA will not change its current plans and seek to finalize the process of listing the Facility on the NPL, or that the ultimate outcome of such a listing will not have a material adverse effect on the Company's financial condition and results of operations.



Item 4.  Submission of Matters to a Vote of Security Holders



The Company held its annual meeting of shareholders on November 8, 2006 for the sole purpose of electing a class of two directors to serve until the annual meeting of the shareholders to be held in 2008.  At the November 8, 2006 meeting, the shareholders elected Dominic J. Monetta and Kevin J. Zugibe as directors of the Company to serve until the annual meeting of the shareholders to be held in 2008, or until their successors have been elected or qualified.  Messrs. Vincent D. Abbatecola, Robert L. Burr and Otto C. Morch continues to serve as director and their term of office expires at the annual meeting of shareholders to be held in 2007.

The number of record holders of the Company's Common Stock was approximately 250 as of March 5, 2007.  The Company believes that there are in excess of 4,000 beneficial owners of its Common Stock.



To date, the Company has not declared or paid any cash dividends on its Common Stock.  The payment of dividends, if any, in the future is within the discretion of the Board of Directors and will depend upon the Company's earnings, its capital requirements and financial condition, borrowing covenants, and other relevant factors.  The Company presently intends to retain all earnings, if any, to finance the Company's operations and development of its business and does not expect to declare or pay any cash dividends on its Common Stock in the foreseeable future.  In addition, the Company has a credit facility with Keltic Financial Partners, LLP ("Keltic") that, among other things, restricts the Company's ability to declare or pay any cash dividends on its capital stock.



See Item 11 for certain information with respect to the Company's equity compensation plans in effect at December 31, 2006.





Item 6.	Management's Discussion and Analysis of Financial Condition and Results of Operations



Safe Harbor Statement Under The Private Securities Litigation Reform Act of 1995



Certain statements contained in this section and elsewhere in this Form 10-KSB constitute "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995.  Such forward-looking statements involve a number of known and unknown risks, uncertainties and other factors which may cause the actual results, performance or achievements of the Company to be materially different from any future results, performance or achievements expressed or implied by such forward-looking statements.  Such factors include, but are not limited to, changes in the demand and price for refrigerants (including unfavorable market conditions adversely affecting the demand for, and the price of refrigerants), the Company's ability to source CFC and non-CFC based refrigerants, regulatory and economic factors, seasonality, competition, litigation, the nature of supplier or customer arrangements that become available to the Company in the future, adverse weather conditions, possible technological obsolescence of existing products and services, possible reduction in the carrying value of long-lived assets, estimates of the useful life of its assets, potential environmental liability, customer concentration, the ability to obtain financing, and other risks detailed in this report and in the Company's other periodic reports filed with the Securities and Exchange Commission.  The words "believe", "expect", "anticipate", "may", "plan", "should" and similar expressions identify forward-looking statements.  Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date the statement was made.



Critical Accounting Policies



The Company's discussion and analysis of its financial condition and results of operations are based upon its 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 the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosure of contingent assets and liabilities.  Several of the Company's accounting policies involve significant judgments, uncertainties and estimations.  The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities.  Actual results may differ from these estimates under different assumptions or conditions.  To the extent that actual results differ from management's judgments and estimates, there could be a material adverse effect on the Company.  On a continuous basis, the Company evaluates its estimates, including, but not limited to, those estimates related to its allowance for doubtful accounts, inventory reserves, valuation allowance for its net operating losses carry forwards ("NOL's") and commitments and contingencies.  With respect to accounts receivable, the Company estimates the necessary allowance for doubtful accounts based on both historical and anticipated trends of payment history and the ability of the customer to fulfill its obligations.  For inventory, the Company evaluates both current and anticipated sales prices of its products to determine if a write down of inventory to net realizable value is necessary. In determining the Company's valuation allowance for its NOL's, the Company assesses its ability to generate taxable income as well as the likelihood that its NOL's may be limited in the future.  The Company utilizes both internal and external sources to evaluate potential current and future liabilities for various commitments and contingencies.  In the event that the assumptions or conditions change in the future, the estimated liabilities could differ from the original estimates.



Overview



The Company has created and developed a service offering known as RefrigerantSide® Services.  RefrigerantSide® Services are sold to contractors and end-users associated with refrigeration systems in commercial air conditioning and industrial processing industries.  These services are offered in addition to refrigerant sales and the Company's traditional refrigerant management services, which consist primarily of reclamation of refrigerants.  The Company has created a network of service depots that provide a full range of the Company's RefrigerantSide® Services to facilitate the growth and development of its service offerings.



The Company focuses its sales and marketing efforts for its RefrigerantSide® Services on customers who the Company believes most readily appreciate and understand the value that is provided by its RefrigerantSide® Services offering.  In pursuing its sales and marketing strategy, the Company offers its RefrigerantSide® Services to customers in the following industries; petrochemical, pharmaceutical, industrial power, manufacturing, commercial facility and property management and maritime.  Moreover, to maintain its current ability to quickly respond to customer service requests throughout the United States, the Company seeks to pursue the creation of strategic alliances with companies that service larger customers in targeted industries, which, when consummated, would enable the Company to (i) co-locate its equipment with these strategic partners and (ii) utilize these partners' sales and marketing resources to offer their customers the Company's RefrigerantSide® Services.  In addition, the Company has expanded its service offering outside of the United States through a strategic alliance with Linde.  The Company may incur additional expenses as it develops its RefrigerantSide® Services.



Sales of refrigerants continue to represent a significant portion of the Company revenues.  Certain of the Company's refrigerant sales are CFC based refrigerants, which are no longer manufactured.  The demand for CFC based refrigerants has and will continue to decrease as equipment that utilize non-CFC based refrigerants displace those units that utilize CFC based refrigerants, particularly in

the automotive aftermarket segment of the refrigerant sales industry.  The Company has increased its refrigerant sales from non-CFC based refrigerants, including HCFC refrigerants.   The Act limits the production of HCFC refrigerants, which production was further limited in January 2004.  Federal regulations enacted in January 2004 also imposed limitations on the importation of certain HCFC refrigerants.  Under the Act, production of certain HCFC refrigerants is scheduled to be phased out by the year 2020, and production of all HCFC refrigerants is scheduled to be phased out by the year 2030.  To the extent that the Company is unable to source CFC based or non-CFC based refrigerants on commercially reasonable terms or at all, or the demand for CFC based or non-CFC based refrigerants decreases, the Company's financial condition and results of operations could be materially adversely affected.



Results of Operations

Year ended December 31, 2006 as compared to the year ended December 31, 2005



Revenues for 2006 were $23,451,000, an increase of $4,228,000 or 22% from the $19,223,000 reported during the comparable 2005 period.  The increase in revenues was primarily attributable to an increase in refrigerant revenues of $3,133,000 and an increase in RefrigerantSide® Services revenues of $1,095,000.  The increase in refrigerant revenues is related to an increase in the volume of refrigerants sold offset by the reduction of the price of certain refrigerants sold.  The increase in RefrigerantSide® Services of $1,095,000 was attributable to an increase in the overall average size and number of jobs completed.



Cost of sales for 2006 was $16,612,000, an increase of $4,304,000 or 35% from the $12,308,000 reported during the comparable 2005 period.  The increase in cost of sales was primarily due to the increase in volume and an increase in cost of refrigerants sold and an increase in the costs of payroll and supply costs of RefrigerantSide® Services.  As a percentage of sales, cost of sales was 71% of revenues for 2006, an increase from the 64% reported for the comparable 2005 period.  The increase in cost of sales as a percentage of revenues was primarily attributable to a decrease in the sales price and an increase in the material costs of certain refrigerants sold, particularly during the first six months of 2006, resulting in lower gross profit margins on the sale of those refrigerants when compared to the same period of 2005.



Operating expenses for 2006 were $4,657,000 an increase of $330,000 or 8% from the $4,327,000 reported during the comparable 2005 period.  The increase was primarily attributable to an increase in selling and administrative payroll expense and an increase in compensation cost of $289,000 associated with the adoption of SFAS 123 (r).



Other income (expense) for 2006 was ($307,000), compared to the ($294,000) reported during the comparable 2005 period.  Other income (expense) includes interest expense of $345,000 and $303,000 for the comparable 2006 and 2005 periods, respectively.  The increase in interest expense is primarily attributed to both an increase in outstanding indebtedness and in the interest rate on the outstanding indebtedness.



Income tax expense (benefit) for the year ended December 31, 2006 and 2005 were ($233,000) and $24,000, respectively.  For the year ended December 31, 2006, the deferred tax benefit of $233,000 consisted of the recognition of a deferred tax asset of $252,000 associated with the Company's NOL's offset by $19,000 of state income tax expense for states that do not allow or limit NOL's.  For the year ended December 31, 2005, income tax expense of $24,000 was recognized for states that either do not allow or limit NOL's.  During the 2006 and 2005 periods no federal or certain state income taxes were recognized on the income before taxes of $1,875,000 and $2,294,000 due to the utilization of NOL's from prior periods.  At December 31, 2006, the Company recognized a reserve allowance of $9,175,000 against the deferred tax benefit for the 2003 and prior losses.  The tax benefits associated with the Company's NOL's are recognized to the extent that the Company is expected to recognize taxable income.  A portion of the Company's NOL's are subject to annual limitations.  In addition, limitations on the amount of the Company's NOL's and on the annual limitations, are expected to occur upon the occurrence of certain events including, without limitation, a change in control, of the Company as defined by the Internal Revenue Service.



Net income for 2006 was $2,108,000 a decrease of $162,000 from the $2,270,000 net income reported during the comparable 2005 period.  The decrease in net income was primarily attributable to an increase in selling, and administrative payroll expenses and an increase in compensation expense of $289,000 associated with the adoption of SFAS 123 (r) offset by the recognition of a deferred tax asset of $252,000.



Liquidity and Capital Resources



At December 31, 2006 the Company had working capital, which represents current assets less current liabilities, of approximately $5,959,000, an increase of $2,072,000 from the working capital of $3,887,000 at December 31, 2005.  The increase in working capital is primarily attributable to the increase in net income.



Inventory and trade receivables are principal components of current assets.  At December 31, 2006, the Company had inventories of $12,393,000, an increase of $6,248,000, or 102% from the $6,145,000 at December 31, 2005.  The increase in the inventory balance is due to the timing and availability of inventory purchases and the sale of refrigerants.  The Company's ability to sell and replace its

inventory on a timely basis and the prices at which it can be sold are subject, among other things, to current market conditions and the nature of supplier or customer arrangements and the Company's ability to source CFC based refrigerants, which are no longer being manufactured or non-CFC based refrigerants (see "Reliance on Suppliers and Customers" and "Seasonality and Fluctuations in Operating Results").  At December 31, 2006, the Company had trade receivables, net of allowance for doubtful accounts of $1,231,000 a decrease of $598,000 or 33% from the $1,829,000 at December 31, 2005.  The Company's trade receivables are concentrated with various wholesalers, brokers, contractors and end-users within the refrigeration industry that are primarily located in the continental United States.



The Company has historically financed its working capital requirements through cash flows from operations, the issuance of debt and equity securities and bank and related party borrowings.



Net cash used by operating activities for the year ended December 31, 2006, was $1,207,000 compared with net cash provided by operating activities of $106,000 for the comparable 2005 period.  Net cash used by operating activities for the 2006 period was primarily attributable to an increase in inventories offset by the net income for the period, a reduction in accounts receivable, and an increase in accounts payable and accrued expenses.



Net cash used by investing activities for the year ended December 31, 2006 was $469,000 compared with net cash used by investing activities of $715,000 for the prior comparable 2005 period.  The net cash used by investing activities for the 2006 period was primarily related to investment in general purpose equipment.



Net cash provided by financing activities for the year ended December 31, 2006, was $1,635,000 compared with net cash provided by financing activities of $628,000 for the comparable 2005 period.  The net cash provided by financing activities for the 2006 period was due to an increase in indebtedness.



At December 31, 2006, the Company had cash and cash equivalents of $593,000.  The Company continues to assess its capital expenditure needs.  The Company may, to the extent necessary, continue to utilize its cash balances to purchase equipment primarily for its operations. The Company estimates that the total capital expenditures for 2007 will be approximately $600,000.



The following is a summary of the Company's significant contractual cash obligations for the periods indicated that existed as of December 31, 2006 and is more fully disclosed in the Notes to the Consolidated Financial Statements (see Notes 7 and 9 to the Notes to the Consolidated Financial Statements) (amounts in thousands of dollars).

|(1) The contractual cash obligations included in the table includes principal payments only.  For the year ended December 31, 2006 the Company recognized interest expense in the amount of $345,000.  The 2006 interest expense was based primarily on the interest rates in effect and the outstanding obligation balances.  It would be expected that in future periods the Company would recognize interest expense on its obligations but such future interest expense is not readily calculable.

|(2) Long and short term debt and capital lease obligations include $3,045,000 outstanding under the revolving line of credit with Keltic.  The Company expects that the revolving line of credit will continue to renew through the term of the credit facility, which expires on May 30, 2008.                                                                                                                                                                                                       



On May 30, 2003, Hudson entered into a credit facility with Keltic that, as amended, provides for borrowings of up to $6,000,000.  The facility consists of a revolving line of credit and a term loan and expires on May 30, 2008.  Advances under the revolving line of credit may not exceed $5,600,000 and are limited to (i) 85% of eligible trade accounts receivable and (ii) 50% of eligible inventory.  Advances available to Hudson under the term loan may not exceed $400,000.  At December 31, 2006, the facility bore interest at an interest rate equal to 9.25 %, which was the prime rate, plus 1%.    Substantially all of Hudson's assets are pledged as collateral for its obligations to Keltic under the credit facility.  In addition, among other things, the agreements restrict Hudson's ability to declare or pay any cash dividends on its capital stock.  As of December 31, 2006, Hudson had in the aggregate $3,045,000 of borrowings outstanding and $2,555,000 available for borrowing under the revolving line of credit.  In addition, the Company had $293,000 of borrowings outstanding under its term loan with Keltic.



On March 31, 2004, the holders of the Company's then outstanding Series A Preferred Stock converted all of their shares of the Series A Preferred Stock into 16,397,468 shares of Common Stock (the "Conversion Shares").  In connection with the purchase, of the Company's Series A Preferred Stock, the holders of the Preferred Stock were provided certain registration, preemptive and tag along rights and such rights continue to be held by the holders of the Conversion Shares.  The holders of the Conversion Shares have the right, for as long as they hold at least thirty-five (35%) percent in the aggregate of the Conversion Shares, or at least 5,739,114 Conversion Shares, to nominate up to two individuals to become members of the Company's Board of Directors, or at their option, to designate up to two advisors to the Company's Board of Directors who will attend and observe meetings of the Board of Directors.  The holders of the Conversion Shares have the right, for as long as they hold at least twenty (20%) percent, or at least 3,279,494 Conversion Shares, but less than thirty-five (35%) percent in the aggregate of the Conversion Shares, to nominate one individual to become a member of the Company's Board of Directors, or at their option, to designate one advisor to the Company's Board of Directors who will attend and observe meetings of the Board of Directors.



In May 2005, the Company purchased the Champaign, Illinois facility for a total purchase price of $999,999.  The Company has financed the purchase with a 15 year amortizing loan in the amount of $945,000 with a balloon payment due on June 1, 2012.  The note bears interest at 7% for the first five years and then adjusts annually based on prime plus 2%.



The Company believes that it will be able to satisfy its working capital requirements for the next twelve months from anticipated cash flows from operations and available funds under its existing credit facility.   Any unanticipated expenses, including, but not limited to, an increase in the cost of refrigerants purchased by the Company, an increase in operating expenses or failure to achieve expected revenues from the Company's RefrigerantSide® Services and/or refrigerant sales or additional expansion or acquisition costs that may arise in the future would adversely affect the Company's future capital needs.  There can be no assurances that the Company's proposed or future plans will be successful, and as such, the Company may require additional capital sooner than anticipated, which capital may not be available.



Inflation



Inflation has not historically had a material impact on the Company's operations.



Reliance on Suppliers and Customers



The Company's financial performance and its ability to sell refrigerants is in part dependent on its ability to obtain sufficient quantities of virgin, non-CFC based refrigerants, and of reclaimable, primarily CFC based, refrigerants from manufacturers, wholesalers, distributors, bulk gas brokers, and from other sources within the air conditioning and refrigeration and automotive aftermarket industries, and on corresponding demand for refrigerants.  The Company's refrigerant sales include CFC based refrigerants, which are no longer manufactured.  Additionally, the Company's refrigerant sales include non-CFC based refrigerants, including HCFC refrigerants.  Effective January 1, 1996, the Act limits the production of HCFC refrigerants, which production was further limited in January 2004.  Federal regulations enacted in January 2004 also imposed limitations on the importation of certain HCFC refrigerants.  Under the Act, the production of certain HCFC refrigerants is scheduled to be phased out by the year 2020 and production of all HCFC refrigerants is scheduled to be phased out by the year 2030.  Notwithstanding the limitations imposed by and under the Act, the Company believes that sufficient quantities of new and used refrigerants will continue to be available to it at a reasonable cost for the foreseeable future.  To the extent that the Company is unable to source sufficient quantities of virgin or reclaimable refrigerants in the future, or resell refrigerants at a profit, the Company's financial condition and results of operations would be materially adversely affected.



For the year ended December 31, 2006, one customer accounted for 10% of the Company's revenues.  For the year ended December 31, 2005, one customer accounted for 13%, and one customer accounts for 11% of the Company's revenues.



The loss of a principal customer or a decline in the economic prospects of and/or a reduction in purchases of the Company's products or services by any such customer could have a material adverse effect on the Company's financial position and results of operations.



Seasonality and Fluctuations in Operating Results



The Company's operating results vary from period to period as a result of weather conditions, requirements of potential customers, non-recurring refrigerant and service sales, availability and price of refrigerant products (virgin or reclaimable), changes in reclamation technology and regulations, timing in introduction and/or retrofit or replacement of CFC based refrigeration equipment, the rate of expansion of the Company's operations, and by other factors.  The Company's business is seasonal in nature with peak sales of refrigerants occurring in the first half of each year.  During past years, the seasonal decrease in sales of refrigerants has resulted in losses particularly in the fourth quarter of the year.  Delays or inability in securing adequate supplies of refrigerants at peak demand periods, lack of refrigerant demand, increased expenses, declining refrigerant prices and a loss of a principal customer could result in significant losses.  There can be no assurance that the foregoing factors will not occur and result in a material adverse effect on the Company's financial position and significant losses.  The Company believes that there is a similar seasonal element to

RefrigerantSide® Service revenues as refrigerant sales.  The Company is continuing to assess its RefrigerantSide® Service revenues seasonal trend.



Recent Accounting Pronouncements



As of January 1, 2006, the Company adopted, utilizing the modified prospective method, the Financial Accounting Standards Board ("FASB") revision of FASB statement No. 123, ("SFAS 123(r)") which requires that the cost resulting from all share-based payment transactions be recognized in the financial statements.  SFAS 123(r) establishes fair value as the measurement objective in accounting for share-based payment arrangements (see Note 11 to the Notes to the Consolidated Financial Statements).



In February 2006, the FASB issued FASB statement No. 155 ("SFAS 155").  SFAS 155 addresses accounting for certain hybrid financial instruments.



In March 2006, the FASB issued FASB statement No. 156 ("SFAS 156").  SFAS 156 addresses accounting for servicing of financial assets.



SFAS 155 and 156 are effective for fiscal years beginning after September 15, 2006.  The Company does not believe that the adoption of these accounting pronouncements will have a material impact on the Company's financial position or results of operations.



In July 2006, the FASB released Interpretation No. 48, Accounting for Uncertainty in Income Taxes (the "Interpretation").  The Interpretation significantly changes the previous guidance for establishing accruals for tax uncertainties.  The Company is required to adopt the Interpretation on January 1, 2007, by adjusting accrued tax liabilities, with an offsetting adjustment to retained earnings.  At this time, the Company does not have enough information to estimate the effect of the Interpretation on tax liabilities or on future years' earnings.



In September 2006, the FASB issued FASB statement No. 157 ("SFAS 157").  SFAS 157 addresses defined fair value, establishes a framework for measuring fair value and expands disclosure for fair value measurements.  SFAS 157 is effective for years beginning after November 15, 2007.  The Company does not believe that the adoption of SFAS 157 will have a material effect on the Company's financial position and results of operations.

Stock Option Plans



1994 Stock Option Plan



We have adopted an Employee Stock Option Plan (the "1994 Plan") effective October 31, 1994 pursuant to which 725,000 shares of Common Stock were reserved for issuance upon the exercise of options designated as either (i) options intended to constitute incentive stock options ("ISOs") under the Internal Revenue Code of 1986, as amended (the "Code"), or (ii) nonqualified options.  ISOs could be granted under the 1994 Plan to our employees and officers.  Non-qualified options could be granted to consultants, directors (whether or not they are employees), our employees or officers.  Effective November 1, 2004, our ability to grant options under the 1994 Plan expired.



All options granted under the 1994 Plan are not transferable during an optionee's lifetime but are transferable at death by will or by the laws of descent and distribution.  In general, upon termination of employment of an optionee, all options granted to such person that are not exercisable on the date of such termination immediately terminate, and any options that are exercisable terminate 90 days following termination of employment.



As of December 31, 2006, we had options outstanding to purchase 108,164 shares of our Common Stock under the 1994 Plan.



1997 Stock Option Plan



We have adopted the 1997 Stock Option Plan (the "1997 Plan"), pursuant to which 2,000,000 shares of our Common Stock are currently reserved for issuance upon the exercise of options designated as either (i) ISOs under the Code, or (ii) nonqualified options.  ISOs may be granted under the 1997 Plan to our employees and officers.  Nonqualified options may be granted to consultants, directors (whether or not they are employees), our employees or officers.  Stock appreciation rights may also be issued in tandem with stock options.



The 1997 Plan is intended to qualify under Rule 16b-3 under the Exchange Act and is administered by the Compensation/Stock Option Committee of our Board of Directors.  The Committee, within the limitations of the 1997 Plan, determines the persons to whom options will be granted, the number of shares to be covered by each option, whether the options granted are intended to be ISOs, the duration and rate of exercise of each option, the exercise price per share and the manner of exercise and the time, manner and form of payment upon exercise of an option.  Unless the 1997 Plan is sooner terminated, the ability to grant options under the 1997 Plan will expire on June 11, 2007.



ISOs granted under the 1997 Plan may not be granted at a ISO's granted to price less than the fair market value of our Common Stock on the date of grant (or 110% of fair market value in the case of ISO's granted to a 10% stockholder).  The aggregate fair market value of shares for which ISOs granted to any employee are exercisable for the first time by such employee during any calendar year (under all of our stock option plans) may not exceed $100,000.  Nonqualified options granted under the 1997 Plan may not be granted at a price less than the par value of the Common Stock.  Options granted under the 1997 Plan will expire not more than ten years from the date of grant (five years in the case of ISOs granted to a 10% stockholder).  Except as otherwise provided by the committee with respect to nonqualified options, all options granted under the 1997 Plan are not transferable during an optionee's lifetime but are transferable at death by will or by the laws of descent and distribution.  In general, upon termination of employment of an optionee, all options granted to such person that are not exercisable on the date of such termination immediately terminate, and any options that are exercisable terminate 90 days following termination of employment.



As of December 31, 2006, we had options outstanding to purchase 1,231,710 shares of our Common Stock and 350,787 shares reserved under the 1997 Plan.



2004 Stock Incentive Plan



We have adopted the 2004 Stock Incentive Plan (the "2004 Plan"), pursuant to which 2,500,000 shares of our Common Stock are currently reserved for issuance upon the exercise of options, designated as either (i) ISOs, or (ii) nonqualified options, or for issuance upon the granting of restricted stock, deferred stock or other stock-based awards.  ISOs may be granted under the 2004 Plan to employees and officers of the Company.  Nonqualified options, restricted stock, deferred stock or other stock-based awards may be granted to consultants, directors (whether or not they are employees), employees or officers of the Company.  Stock appreciation rights may also be issued in tandem with stock options.



The 2004 Plan is intended to qualify under Rule 16b-3 under the Exchange Act and is administered by our Compensation/Stock Option Committee of our Board of Directors.  The Committee, within the limitations of the 2004 Plan, determines the persons to whom options will be granted, the number of shares to be covered by each option, whether the options granted are intended to be ISOs, the duration and rate of exercise of each option, the exercise price per share and the manner of exercise and the time, manner and form of payment upon exercise of an option.  In the case of restricted stock, deferred stock or other stock-based awards, the Committee, within the limitations of the 2004 Plan, determines the persons to whom awards will be granted, the number of shares of stock subject to the award, and the restrictions on issuance and transfer of such shares.  Unless the 2004 Plan is sooner terminated, the ability to grant options or other awards under the 2004 Plan will expire on September 10, 2014.



Options granted under the 2004 Plan may not be granted at a price less than the fair market value of the Common Stock on the date of grant (or 110% of fair market value in the case of ISOs granted to a 10% stockholder).  In the case of ISOs, the aggregate fair market value of shares for which ISOs granted to any employee are exercisable for the first time by such employee during any calendar year (under all our stock option plans) may not exceed $100,000.  Nonqualified options granted under the 2004 Plan may not be granted at a price less than the fair market value of our Common Stock.  Options granted under the 2004 Plan will expire not more than ten years from the date of grant (five years in the case of ISOs granted to a 10% stockholder).  Except as otherwise provided by the Committee with respect to nonqualified options, all options, restricted stock, deferred stock or other stock-based awards granted under the 2004 Plan are not transferable during an grantee's lifetime but are transferable at death by will or by the laws of descent and distribution.  In general, upon termination of employment of a grantee, all options, restricted stock, deferred stock or other stock-based awards granted to such person which are not exercisable on the date of such termination immediately terminate, and any options that are exercisable terminate 90 days following termination of employment.



As of December 31, 2006, we had options outstanding to purchase 947,269 shares of Common Stock and 1,550,000 shares reserved under the 2004 plan.



Director Compensation

The chairman of the Company's Audit Committee receives additional compensation of $2,000 per year, and each independent member of our Audit Committee (excluding the Chairman) receives additional compensation of $1,000 per year.

Report of Independent Registered Public Accounting Firm



To Stockholders and Board of Directors



Hudson Technologies, Inc.

Pearl River, New York



We have audited the accompanying consolidated balance sheet of Hudson Technologies, Inc. and subsidiaries as of December 31, 2006 and the related consolidated statements of income, stockholders' equity and cash flows for each of the two years in the period ended December 31, 2006.  These financial statements are the responsibility of the Company's management.  Our responsibility is to express an opinion on these consolidated financial statements based on our audits.



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



In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Hudson Technologies, Inc. and subsidiaries as of December 31, 2006 and the results of their operations and their cash flows for each of the two years in the period ended December 31, 2006 in conformity with accounting principles generally accepted in the United States.



As discussed in Note 1, to the Notes to the Consolidated Financial Statements, effective January 1, 2006, the Company adopted Statement of Financial Accounting Standards No. 123(r).

Hudson Technologies, Inc. and subsidiaries

Notes to the Consolidated Financial Statements



Note 1-	Summary of Significant Accounting Policies



Business



Hudson Technologies, Inc., incorporated under the laws of New York on January 11, 1991, together with its subsidiaries (collectively, "Hudson" or the "Company"), is a refrigerant services company providing innovative solutions to recurring problems within the refrigeration industry.  The Company's products and services are primarily used in commercial air conditioning, industrial processing and refrigeration systems, including (i) refrigerant sales, (ii) RefrigerantSide® Services performed at a customer's site, consisting of system decontamination to remove moisture, oils and other contaminants and (iii) refrigerant management services consisting primarily of reclamation of refrigerants.  The Company operates through its wholly-owned subsidiary, Hudson Technologies Company.



Consolidation



The consolidated financial statements represent all companies of which Hudson directly or indirectly has majority ownership or otherwise controls.  Significant intercompany accounts and transactions have been eliminated.  The Company's consolidated financial statements include the accounts of wholly-owned subsidiaries Hudson Holdings, Inc. and Hudson Technologies Company.



Reclassification



Certain account balances have been reclassified for comparative purposes.



Fair value of financial instruments



The carrying values of financial instruments including trade accounts receivable, and accounts payable approximate fair value at December 31, 2006, because of the relatively short maturity of these instruments.  The carrying value of short-and long-term debt approximates fair value, based upon quoted market rates of similar debt issues, as of December 31, 2006.



Credit risk



Financial instruments, which potentially subject the Company to concentrations of credit risk, consist principally of temporary cash investments and trade accounts receivable.  The Company maintains its temporary cash investments in highly-rated financial institutions and, at times, the balances exceed FDIC insurance coverage.  The Company's trade accounts receivables are primarily due from companies throughout the United States.  The Company reviews each customer's credit history before extending credit.



The Company establishes an allowance for doubtful accounts based on factors associated with the credit risk of specific accounts, historical trends, and other information.  The carrying value of the Company's accounts receivable is reduced by the established allowance for doubtful accounts.  The allowance for doubtful accounts includes any accounts receivable balances that are determined to be uncollectible, along with a general reserve for the remaining accounts receivable balances.  The Company may adjust its general or specific reserves based on factors that affect the collectability of the accounts receivable balances.



For the year ended December 31, 2006, one customer accounted for 10% of the Company's revenues.  For the year ended December 31, 2005, one customer accounted for 13% and one customer accounted for 11% of the Company's revenues.



The loss of a principal customer or a decline in the economic prospects of and/or a reduction in purchases of the Company's products or services by any such customer could have an adverse effect on the Company's future financial position and results of operations.



Cash and cash equivalents



Temporary investments with original maturities of ninety days or less are included in cash and cash equivalents.



Inventories



Inventories, consisting primarily of refrigerant products available for sale, are stated at the lower of cost, on a first-in first-out basis, or market.





Property, plant, and equipment



Property, plant, and equipment are stated at cost, including internally manufactured equipment.  The cost to complete equipment that is under construction is not considered to be material to the Company's financial position.  Provision for depreciation is recorded (for financial reporting purposes) using the straight-line method over the useful lives of the respective assets.  Leasehold improvements are amortized on a straight-line basis over the shorter of economic life or terms of the respective leases.  Costs of maintenance and repairs are charged to expense when incurred.



Due to the specialized nature of the Company's business, it is possible that the Company's estimates of equipment useful life periods may change in the future.



Revenues and cost of sales



Revenues are recorded upon completion of service or product shipment and passage of title to customers in accordance with contractual terms.  The Company evaluates each sale to ensure collectability.  In addition, each sale is based on an arrangement with the customer and the sales price to the buyer is fixed.  License fees are recognized over the period of the license based on the respective performance measurements associated with the license.  Royalty revenues are recognized when earned.  Cost of sales is recorded based on the cost of products shipped or services performed and related direct operating costs of the Company's facilities.  To the extent that the Company charges its customers shipping fees such amounts are included as a component of revenue and the corresponding costs are included as a component of cost of sales.



The Company's revenues are derived from refrigerant and reclamation sales and RefrigerantSide® Services, including license and royalty revenues.  The revenues for each of these lines are as follows:





|Year Ended December 31,           | 2006    | 2005    
|--------------------------------- | ------- | --------
|(in thousands)                    |         |         
|Refrigerant and reclamation sales | $18,855 | $15,722 
|RefrigerantSide® Services         | 4,596   | 3,501   
|Total                             | $23,451 | $19,223 
|                                  | ======= | ========



Income taxes



The Company utilizes the asset and liability method for recording deferred income taxes, which provides for the establishment of deferred tax asset or liability accounts based on the difference between tax and financial reporting bases of certain assets and liabilities.



The tax benefit associated with the Company's net operating loss carry forwards ("NOL's") is recognized to the extent that the Company is expected to recognize net income.  The Company expects that its NOL's will be further limited upon the occurrence of certain events, including, without limitations, a change in control, of the Company as defined by the Internal Revenue Service.  In addition, certain states either do not allow or limit NOL's and as such the Company will be liable for certain state taxes even though for federal tax purposes the Company has NOL's and will not pay federal taxes.



Income per common and equivalent shares



If dilutive, common equivalent shares (common shares assuming exercise of options and warrants) utilizing the treasury stock method are considered in the presentation of dilutive earnings per share.  For the years ended December 31, 2006 and 2005, the number of common equivalent shares included and excluded in the calculation of dilutive income per common share was 1,510,450 and 940,050, and 1,289,183 and 1,215,012, respectively.  In 2006 and 2005, the effect on net income per share of equivalent shares was not dilutive.



Estimates and risks



The preparation of financial statements in conformity with generally accepted accounting principles in the United States requires management to make estimates and assumptions that affect reported amounts of certain assets and liabilities, the disclosure of contingent assets and liabilities, and the results of operations during the reporting period.  Actual results could differ from these estimates.



The Company participates in an industry that is highly regulated, changes in which could affect operating results.  Currently the Company purchases virgin, non chlorofluorocarbon ("CFC") based, and reclaimable, primarily CFC based, refrigerants from suppliers and its customers.  Effective January 1, 1996, the Clean Air Act (the "Act") prohibited the production of CFC refrigerants and limited the production of hydrochlorofluorocarbons ("HCFC") refrigerants.  Additionally, effective January 2004, the Act further limited the production of HCFC refrigerants and federal regulations were enacted which impose limitations on the importation of certain virgin

HCFC refrigerants.  Under the Act, production of certain HCFC refrigerants is scheduled to be phased out by the year 2020, and production of all HCFC refrigerants is scheduled to be phased out by 2030.  Notwithstanding the limitations under the Act, the Company believes that sufficient quantities of new and used refrigerants will continue to be available to it at a reasonable cost for the foreseeable future.  To the extent that the Company is unable to source sufficient quantities of refrigerants or is unable to obtain refrigerants on commercially reasonable terms or experiences a decline in demand for refrigerants, the Company could realize reductions in refrigerant processing and possible loss of revenues, which would have a material adverse affect on operating results.



The Company is subject to various legal proceedings.  The Company assesses the merit and potential liability associated with each of these proceedings.  In addition, the Company estimates potential liability, if any, related to these matters.  To the extent that these estimates are not accurate, or circumstances change in the future, the Company could realize liabilities, which would have a material adverse effect on operating results and its financial position.



Impairment of long-lived assets and long-lived assets to be disposed of



The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable.  Recoverability of assets to be held and used is measured by a comparison of the carrying amount of the assets to the future net cash flows expected to be generated by the asset.  If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets.  Assets to be disposed of are reported at the lower of the carrying amount or fair value less the cost to sell.



Stock options



As of January 1, 2006, the Company accounts for its stock options, utilizing the modified prospective method, pursuant to the revision of Financial Accounting Standard Board ("FASB") statement SFAS No. 123(r) ("SFAS No. 123(r)") (see Note 11 to the Notes to the Consolidated Financial Statements).  Prior to January 1, 2006, the Company had used the intrinsic value method of accounting for employee stock options as permitted by SFAS No. 123, "Accounting for Stock-Based Compensation."  Accordingly, compensation cost for stock options has been measured as the excess, if any, of the quoted market price of Company stock at the date of the grant over the amount the employee must pay to acquire the stock.  The compensation cost is recognized over the vesting period of the options.  For the prior year's reporting period both the stock-based employee compensation cost included in the determination of the net income as reported and the stock-based employee compensation cost that would have been included in the determination of net income if the fair value based method had been applied to all awards, as well as the resulting pro forma net income and net income per share using the fair value approach, are presented in the following table.

SFAS 155 and 156 are effective for fiscal years beginning after September 15, 2006.  The Company does not believe that the adoption of these accounting pronouncements will have a material impact on the Company's financial position or results of operations.



In July 2006, the FASB released Interpretation No. 48, Accounting for Uncertainty in Income Taxes (the "Interpretation").  The Interpretation significantly changes the previous guidance for establishing accruals for tax uncertainties.  The Company is required to adopt the Interpretation on January 1, 2007, by adjusting accrued tax liabilities, with an offsetting adjustment to retained earnings.  At this time, the Company does not have enough information to estimate the effect of the Interpretation on tax liabilities or on future years' earnings.



In September 2006, the FASB issued FASB statement No. 157 ("SFAS 157").  SFAS 157 addresses defined fair value, establishes a framework for measuring fair value and expands disclosure for fair value measurements.  SFAS 157 is effective for years beginning after November 15, 2007.  The Company does not believe that the adoption of SFAS 157 will have a material effect on the Company's financial position and results of operations.



Note 2 - Other income



For the year ended December 31, 2006 and 2005 other income consisted of dividend income of $38,000 and $9,000 respectively.



Note 3 - Income taxes



During the year ended December 31, 2006 and 2005 no current federal and certain state income taxes were recognized on the income before taxes due to the utilization of NOL's from prior periods. For the year ended December 31, 2006, the Company recognized a $252,000 deferred tax asset and a corresponding $252,000 tax benefit offset by $19,000 tax expense for state income taxes for those states that do not allow or limit NOL's.  For the year ended December 31, 2005, the tax provision of $24,000 reflects state income taxes for those states that do not allow or limit NOL's.



Reconciliation of the Company's actual tax rate to the U.S. Federal statutory rate is as follows:

As of December 31, 2006, the Company has NOL's of approximately $25,000,000 expiring 2007 through 2023.  Included in the NOL's are NOL's acquired during 1995 in the amount of approximately $4,488,000, which are currently subject to annual limitations of approximately $367,000 and expire from 2007 through 2010.  As of December 31, 2006, of the NOL's acquired during 1995, $620,000 of the NOL's remain that are subject to the annual limitation of $367,000.  Further limitations on the amount of the Company's NOL's and on the annual limitations, are more likely than not expected to occur upon the occurrence of certain events including, without limitation, a change in control of the Company, as defined by the Internal Revenue Service.

Bank credit line and term loan



On May 30, 2003, Hudson entered into a credit facility with Keltic Financial Partners, LLP ("Keltic") that, as amended, provides for borrowings of up to $6,000,000.  The facility consists of a revolving line of credit and a term loan and expires on May 30, 2008.  Advances under the revolving line of credit may not exceed $5,600,000 and are limited to (i) 85% of eligible trade accounts receivable and (ii) 50% of eligible inventory.  Advances available to Hudson under the term loan may not exceed $400,000.  At December 31,

2006, the facility bore interest at an interest rate equal to 9.25%, which was the prime rate plus 1%.   Substantially all of Hudson's assets are pledged as collateral for its obligations to Keltic under the credit facility.  In addition, among other things, the agreements restrict Hudson's ability to declare or pay any cash dividends on its capital stock.  As of December 31, 2006, Hudson had in the aggregate $3,045,000 of borrowings outstanding and $2,555,000 available for borrowing under the revolving line of credit.  In addition, the Company had $293,000 of borrowings outstanding under its term loan with Keltic.  During 2006, the Company exceeded its annual limitation for the capital expenditures unders its credit facility for which a waiver was obtained.



Building Mortgage



In May 2005, the Company purchased the Champaign, Illinois facility for a total purchase price of $999,999.  The Company has financed the purchase with a 15 year amortizing loan in the amount of $945,000 with a balloon payment due on June 1, 2012.  The note bears interest at 7% for the first five years and then adjusts annually based on prime plus 2%.  As of December 31, 2006, the Company has approximately $888,000 outstanding under the loan.

Legal Proceedings



On April 1, 1999, the Company reported a release of approximately 7,800 lbs. of R-11 refrigerant (the "1999 Release"), at its leased facility in Hillburn, NY, which was vacated in June 2006 ("Facility").  A failed hose connection to one of the Company's outdoor storage tanks allowed liquid R-11 to discharge from the tank into the concrete secondary containment area in which the subject tank was located.



Between April 1999 and May 1999, with the approval of the New York State Department of Environmental Conservation ("DEC"), the Company constructed and put into operation a remediation system to remove R-11 levels in the groundwater under and around the  Facility.



In September 2000, the Company signed an Order on Consent with the DEC, which was amended in May 2001, whereby the Company agreed to operate the remediation system and perform monthly testing at the Facility, until remaining groundwater contamination has been effectively abated.  In July 2005, the DEC approved a modification of the Order on Consent to reduce the frequency of testing from monthly to quarterly.  The Company is continuing to operate the remediation system pursuant to the approved modifications to that Order on Consent and, as of December 31, 2006, the Company has accrued, as an expense in its consolidated financial statements, the costs that the Company believes it will incur in connection with its compliance with the Order on Consent through December 31, 2009.  There can be no assurance that additional testing will not be required or that the Company will not incur additional costs, and such costs in excess of the Company's estimate may have a material adverse effect on the Company financial condition or results of operations.



In May 2000, the Facility, as a result of the 1999 release, was nominated by the EPA for listing on the National Priorities List ("NPL") pursuant to CERCLA.  The Company submitted opposition to the listing within the sixty-day comment period.  In September 2003, the EPA advised the Company that it has no current plans to finalize the process for listing of the Facility on the NPL and that the EPA will not withdraw the proposal for listing on the NPL.



In October 2001, the Company learned that trace levels of R-11 were detected in one of the wells operated by United Water of New York, Inc. ("United") that is in the closest proximity to the Village of Suffern's ("Village") well system.  No contamination of R-11

has ever been detected in any of the Village's wells and, since October 2002, the level of R-11 in the United well closest to the Village has been below 1 ppb.  In September 2004, the Village advised that it intends to continue performing additional sampling of its wells at a cost of approximately $5,000 per year and the Company has reimbursed the Village for sampling costs through September 2005.



The Company has exhausted all insurance proceeds available for the 1999 Release under all applicable policies.



During the year ended December 31, 2006, the Company incurred $47,000 in additional remediation costs in connection with the matters above and such amount has been included as a component of general and administrative expenses.  There can be no assurance that the 1999 Release will not impact the Village wells, or that the ultimate outcome of the 1999 Release will not have a material adverse effect on the Company's financial condition and results of operations.  There can be no assurance that the EPA will not change its current plans and seek to finalize the process of listing the Facility on the NPL, or that the ultimate outcome of such a listing will not have a material adverse effect on the Company's financial condition and results of operations.



Employment Agreements



The Company has entered into a two-year employment agreement with Kevin J. Zugibe, which expires in October 2008 and is automatically renewable for successive two-year terms unless either party gives notice of termination at least ninety days prior to the then expiration date of the then current term.  Pursuant to the agreement, Mr. Zugibe is receiving an annual base salary of $179,000 with such increases and bonuses as the Board may determine.  The Company is the beneficiary of a "key-man" insurance policy on the life of Mr. Zugibe in the amount of  $1,000,000.



Note 11 - Share-Based Compensation



Share-based compensation represents the cost related to share-based awards, typically stock options, granted to employees, non-employees, officers and directors.  Share-based compensation is measured at grant date, based on the estimated fair value of the award, and such amount is charged to compensation expense on a straight-line basis (net of estimated forfeitures) over the requisite service period.  For the year ended December 31, 2006, the share-based compensation expense of $289,000 is reflected in general and administrative expenses in the consolidated income statement.



Share-based awards have historically been stock options issued pursuant to the terms of the Company's 1994, 1997 and 2004 stock option plans (the "Plans"), described below.  The Compensation Committee and the Board of Directors administer the Plans.  As of December 31, 2006, the Plans authorized the issuance of stock options to purchase 4,500,000 shares of the Company's Common Stock and, as of December 31, 2006, there were 1,900,787 shares of the Company's Common Stock available for issuance for future stock option grants.



Stock options are awards, which allow the recipient to purchase shares of the Company's Common Stock at a fixed price, are typically granted at an exercise price equal to the Company's stock price at the date of grant.  Typically, the Company's stock option awards are expected to vest over two years from the grant date and are expected to have a contractual term of five to ten years.  The Company estimates the fair value of all share-based compensation using a Black-Scholes valuation model.



During the year ended December 31, 2006, the Company issued 206,700 stock options and the fair value of these awards was $182,000. At December 31, 2006, total unrecognized compensation cost related to non-vested previously granted option awards was $88,000 which is expected to be recognized over a period of approximately one year.



Effective October 31, 1994, the Company adopted an Employee Stock Option Plan ("1994 Plan") pursuant to which 725,000 shares of Common Stock were reserved for issuance upon the exercise of options designated as either (i) options intended to constitute incentive stock options ("ISOs") under the Internal Revenue Code of 1986, as amended, ("Code") or (ii) nonqualified options.  ISOs could be granted under the 1994 Plan to employees and officers of the Company.  Non-qualified options could be granted to consultants, directors (whether or not they are employees), employees or officers of the Company.  Effective November 1, 2004, the Company's ability to grant options under the 1994 Plan expired.



Effective July 25, 1997, the Company adopted its 1997 Employee Stock Option Plan, which was amended on August 19, 1999, ("1997 Plan") pursuant to which 2,000,000 shares of Common Stock are currently reserved for issuance upon the exercise of options designated as either (i) ISOs under the Code, or (ii) nonqualified options.  ISOs may be granted under the 1997 Plan to employees and officers of the Company.  Non-qualified options may be granted to consultants, directors (whether or not they are employees), employees or officers of the Company.  Stock appreciation rights may also be issued in tandem with stock options.  Unless the 1997 Plan is sooner terminated, the ability to award options under the 1997 Plan will expire on June 11, 2007.



ISOs granted under the 1997 Plan may not be granted at a price less than the fair market value of the Common Stock on the date of grant (or 110% of fair market value in the case of a persons holding 10% or more of the voting stock of the Company).  Non-qualified options granted under the 1997 Plan may not be granted at a price less than the par value of the Common Stock.  Options granted

under the 1997 Plan expire not more than ten years from the date of grant (five years in the case of ISOs granted to persons holding 10% or more of the voting stock of the Company).



Effective September 10, 2004, the Company adopted its 2004 Stock Incentive Plan  ("2004 Plan") pursuant to which 2,500,000 shares of Common Stock are currently reserved for issuance upon the exercise of options, designated as either (i) ISOs under the Code or (ii) nonqualified options, restricted stock, deferred stock or other stock-based awards.  ISOs may be granted under the 2004 Plan to employees and officers of the Company.  Non qualified options, restricted stock, deferred stock or other stock-based awards may be granted to consultants, directors (whether or not they are employees), employees or officers of the Company.  Stock appreciation rights may also be issued in tandem with stock options.  Unless the 2004 Plan is sooner terminated, the ability to grant options or other awards under the 2004 Plan will expire on September 10, 2014.



Options granted under the 2004 Plan may not be granted at a price less than the fair market value of the Common Stock on the date of grant (or 110% of fair market value in the case of persons holding 10% or more of the voting stock of the Company).  Non-qualified options granted under the 2004 Plan may not be granted at a price less than the fair market value of the Common Stock.  Options granted under the 2004 Plan expire not more than ten years from the date of grant (five years in the case of ISOs granted to persons holding 10% or more of the voting stock of the Company).



All stock options have been granted to employees and non-employees at exercise prices equal to or in excess of the market value on the date of the grant.



On December 13, 2005, the Company's Board of Directors approved the acceleration of the vesting of certain unvested options awarded under the 1997 Plan on September 30, 2005 to the executive officers and to two other key employees of the Company.  As a result of this action, options to purchase a total of 65,625 shares of the Company's Common Stock that were granted under the 1997 Plan on September 30, 2005, vested in full effective December 14, 2005.  The closing market price of the Company's Common Stock on December 14, 2005 was $2.01.  Since the exercise price of the options subject to acceleration was above the closing market price as of the effective date of the acceleration, the options subject to acceleration had no economic value to the holders on the date of acceleration, and the Company incurred no stock based compensation expense as a result of the acceleration of these options.  The purpose of accelerating the vesting of these outstanding previously unvested options was to enable the Company to avoid recognizing stock based compensation expense associated with these options in future periods as required by Statement of Financial Accounting Standard No. 123 (revised 2004), "Share-Based Payment" ("SFAS 123(r)"), which was adopted in January 2006.



The Company determines the fair value of shared based awards at the grant date by using the Black-Scholes option-pricing model, and is incorporating the simplified method to compute expected lives of share based awards with the following weighted-average assumptions used for grants since 1995.
