Documents incorporated by reference: None

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, and include (i) refrigerant sales, (ii) refrigerant management services consisting primarily of reclamation of refrigerants and (iii) RefrigerantSide® Services performed at a customer's site, consisting of system decontamination to remove moisture, oils and other contaminants. In addition, RefrigerantSide® Services include predictive and diagnostic services for industrial and commercial refrigeration applications, which are designed to predict potential catastrophic problems and identify inefficiencies in an operating system. The Company's Chiller Chemistry®, Chill Smart®, Fluid Chemistry™ and Performance Optimization are predictive and diagnostic service offerings. 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 One Blue Hill Plaza, Pearl River, New York and its telephone number is (845) 735-6000.

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, as amended (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.

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. 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 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®. 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. Fluid Chemistry™, an abbreviated version of, the Company's Chiller Chemistry® offering, is designed to quickly identify systems that require further examination. 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 a 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 carbon dioxide ("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®.

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.

The Company provides a complete offering of refrigerant management services, which primarily include reclamation of refrigerants, laboratory testing, through the Company's laboratory, which has been certified by the Air Conditioning, Heating and Refrigeration Institute, formerly the Air Conditioning and Refrigeration Institute, ("ARI") 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 operates from a network of facilities located in:

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 (i) a license fee payable to the Company by the Linde affiliate in annual installments during the course of such supplemental agreement and (ii) 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.

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 CFC and non-CFC based, refrigerants from manufacturers, 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, which are the most widely used 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, 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. The limitations imposed by and under the Act may limit supplies of virgin refrigerants for the foreseeable future or cause a significant increase in the price of virgin HCFC refrigerants. 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.

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, 2008, no one customer accounted for more than 10% of the Company's revenues. For the year ended December 31, 2007, one customer accounted for approximately 12%, of the Company's revenues.

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 through the Company's website (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.

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 marketplace 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.

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.

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 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 imposes 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, as amended ("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, as amended 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, as amended 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.

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.

The Company has 77 full and 3 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.

The Company holds a United States patent and eight foreign patents covering seventeen foreign countries and has patent applications pending in two other foreign countries all relating to the high-speed equipment, components and process to reclaim refrigerants. The Company also holds 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 U.S. 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.

There are many important factors that have affected, and in the future could affect the Hudson'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 Hudson's control and future trends are difficult to predict.

Our existing credit facility, which currently expires in June 2011, is secured by substantially all of our assets and contains formulas that limit the amount of our borrowings under the facility. Moreover, the terms of our credit facility also include negative covenants that, among other things, may limit our ability to incur additional indebtedness. If we violate any of these loan covenants our indebtedness under the credit facility would become immediately due and payable, and the banks could foreclose on its security, which could materially adversely affect our business and future financial condition and could require us to curtail or otherwise cease our existing operations.

Our capital requirements have been and may be significant in the future. In the future, we may incur additional expenses in the development and implementation of our operations. Due to fluctuations in the price, demand and availability of new refrigerants, our existing bank facility that expires in June 2011 may not in the future be sufficient to provide all of the capital that we need to acquire and manage our inventories of new refrigerant. As a result, we may be required to seek additional equity or debt financing in order to develop our RefrigerantSide Services business our refrigerant sales business and our other businesses. We have no current arrangements with respect to, or sources of, additional financing other than our existing bank credit facility.. There can be no assurance that we will be able to renew this credit facility or obtain any additional financing on terms acceptable to us or at all. Our inability to obtain financing, if and when needed, could materially adversely affect our business and future financial condition and could require us to curtail or otherwise cease our existing operations.

Our business could be negatively impacted by the current economic downturn. If this downturn is prolonged or worsens, there could be several severely negative implications to our business that may exacerbate many of the risk factors we identified in this report, but not limited, to the following:

The economic downturn and the associated credit crisis could continue or worsen and reduce liquidity and this could have a negative impact on financial institutions and the global financial system, which could, in turn, have a negative impact on us.

We may not be able to borrow additional funds under our existing credit facilities and may not be able to expand our existing facility if participating lenders become in-solvent or their liquidity is limited or impaired. In addition, we may not be able to renew our existing credit facility at the conclusion of its current term.

The economic downturn has resulted in severe job losses and lower business to business and consumer confidence, which could cause a decrease in demand and/or price for our product and services.

The refrigerant recovery and reclamation industry involves potentially significant risks of statutory and common law liability for environmental damage and personal injury. We, and in certain instances, our officers, directors and employees, may be subject to claims arising from our 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. We may be strictly liable for damages, which could be substantial, regardless of whether we exercised due care and complied with all relevant laws and regulations. Our 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 us, if successful and of sufficient magnitude would have a material adverse effect on our business and financial condition.

Our 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 us. Failure by government authorities to otherwise continue to enforce existing regulations or significant relaxation of regulatory requirements could also adversely affect demand for our services and products.

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 we believe that we are in substantial compliance with all material regulations relating to our 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 us to continually alter our methods of operation and/or discontinue the sale of certain of our products resulting in costs to us that could be substantial. We may not be able, for financial or other reasons, to comply with applicable laws, regulations and permit requirements, particularly as we seek to enter into new geographic markets. Our failure to comply with applicable laws, rules or regulations or permit requirements could subject us to civil remedies, including substantial fines, penalties and injunctions, as well as possible criminal sanctions, which would, if of significant magnitude, materially adversely impact our operations and future financial condition.

The markets for our services and products are highly competitive. We compete with numerous regional and national companies which provide refrigerant recovery and reclamation services, as well as companies which market and deal in new and reclaimed alternative refrigerants, including certain of our suppliers, some of which possess greater financial, marketing, personnel and other resources than us. We also compete 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. We may not be able to compete successfully, particularly as we seek to enter into new markets.

Refrigerant sales continue to represent a significant portion of our revenues. Therefore, our 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 legislative limitations and ban 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. We do not maintain firm agreements with any of our suppliers of refrigerants. Sufficient amounts of new and/or used refrigerants may not be available to us in the future, or may not be available on commercially reasonable terms. Additionally, we may be subject to price fluctuations, periodic delays or shortages of new and/or used refrigerants. Our 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 our operating margins and results of operations.

Our success is largely dependent upon the efforts of our Chief Executive Officer and Chairman. The loss of his services would have a material adverse effect on our business and prospects.

Our Certificate of Incorporation authorizes our 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 our 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 by us in the future. Our 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 us.

Our common stock is currently listed on the NASDAQ Capital Market. We must comply with numerous NASDAQ MarketPlace rules in order to continue the listing of our common stock on NASDAQ. There can be no assurance that we can continue to meet the rules required to maintain the NASDAQ listing of our common stock. If we are unable to maintain our listing on NASDAQ, the market liquidity of our common stock may be severely limited.

Currently, our officers and directors collectively own approximately 39% of our outstanding common stock. Accordingly, our officers and directors are in a position to significantly effect, and potentially fully control us and the election of our directors. There is no provision for cumulative voting for our directors.

In addition to the above leases, the Company from time to time utilizes public warehouse space on a month to month basis. The Company typically enters into short-term leases for its facilities and whenever possible extends the expiration date of such leases. The Company believes that its insurance policies are adequate to protect the Company's property.

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 the Company 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, 2008, 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 March 31, 2010. 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, 2008, the Company incurred $34,000 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.

None.

Certain statements contained in this section and elsewhere in this Form 10-K 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 ("SEC"). 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.

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 consolidated 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 the deferred tax assets relating to its net operating loss 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 deferred tax assets, the Company assesses its ability to generate taxable income 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 estimates could differ from the original estimates.

The Company has created and developed a service offering known as RefrigerantSide® Services. RefrigerantSide® Services are sold to contractors and end-users whose refrigeration systems are used in commercial air conditioning and industrial processing. 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. In addition, the Company has expanded its service offering outside of the United States through a strategic alliance with the Linde Group. The Company may incur additional expenses as it develops its RefrigerantSide® Services offering.

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 utilizes non-CFC based refrigerants displaces those units that utilize CFC based refrigerants. The Company has increased its refrigerant sales from non-CFC based refrigerants, including HCFC and HFC 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 are scheduled to be phased out during the period 2010 through 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.

Revenues for the fiscal year ended December 31, 2008 were $33,167,000 an increase of $6,273,000 or 23% from the $26,894,000 reported during the comparable 2007 period. The increase in revenues was primarily attributable to an increase in refrigerant revenues of $6,583,000 offset by a decrease in RefrigerantSide® Services revenues of $310,000. The increase in refrigerant revenues is primarily related to an increase in the sales price of certain refrigerants sold in the 2008 period amounting to $8,284,000 offset by a decrease in the number of pounds sold amounting to $1,701,000. In 2007, the Company completed refrigerant sales to a large customer at a lower margin than those made by the Company during the 2008 period. The Company subsequently chose to discontinue refrigerant sales to this customer and has substantially replaced most of this volume with various smaller transactions at higher margins. The decrease in RefrigerantSide® Services was primarily attributable to a decrease in the numbers of jobs completed when compared to the same period of 2007.

Cost of sales for the fiscal year ended December 31, 2008 was $21,857,000, an increase of $1,816,000 or 9% from the $20,041,000 reported during the comparable 2007 period. The increase in cost of sales was primarily due to an increase in cost of certain refrigerants sold. As a percentage of sales, cost of sales was 66% of revenues for 2008, a decrease from the 75% reported for the comparable 2007 period. The decrease in cost of sales as a percentage of revenues was primarily attributable to an increase in the sales price of certain refrigerants sold when compared to the same period of 2007.

Operating expenses for the fiscal year ended December 31, 2008 were $5,894,000 a decrease of $3,313,000 from the $9,207,000 reported during the comparable 2007 period. The decrease in operating expenses was primarily related to a reduction in compensation expense attributed to the non-cash, non-recurring charge of $4,338,000 in connection with the 9,200,000 of our common stock shares purchased by certain members of the Company's management from the Fleming Funds that occurred during the 2007 period partially offset by increased payroll expenses and professional fees.

Other income (expense) for the fiscal year ended December 31, 2008 was ($1,167,000), compared to the ($746,000) reported during the comparable 2007 period. Other income (expense) includes interest expense of $1,170,000 and $768,000 for the comparable 2008 and 2007 periods, respectively. The increase in interest expense is primarily attributed to an increase in outstanding indebtedness.

Income tax benefit for the fiscal year ended December 31, 2008 and 2007 was $2,420,000 and $1,139,000 respectively. For the year ended December 31, 2008, the income tax expense of $180,000 for federal and state income taxes was offset by an increase in the tax benefit by $2,600,000. The tax benefits associated with the Company's NOL's are recognized to the extent that the Company is expected to recognize taxable income in future periods. The Company's NOL's are subject to annual limitations and the Company expects to continue to incur certain state, federal and/or federal alternative minimum taxes for the foreseeable future.

Net income for the fiscal year ended December 31, 2008 was $6,669,000 an increase of $8,630,000 from the ($1,961,000) net loss reported during the comparable 2007 period. The increase in net income in the 2008 period was primarily due to an increase in gross profit from an increase in refrigerant revenues and the absence of the $4,338,000 of compensation expense recorded in the 2007 period, as well as an increase in the income tax benefit recorded in 2008 when compared to 2007.

At December 31, 2008, the Company had working capital, which represents current assets less current liabilities, of $11,099,000 an increase of $3,556,000 from the working capital of $7,543,000 at December 31, 2007. The increase in working capital is primarily attributable to net income during the 2008 period.

Inventory and trade receivables are principal components of current assets. At December 31, 2008, the Company had inventories of $23,613,000 an increase of $11,011,000 or 87% from the $12,602,000 at December 31, 2007. The increase in the inventory balance is due to the timing and availability of inventory purchases and the sale of refrigerants and the increase in the unit cost of certain 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. At December 31, 2008, the Company had trade receivables, net of allowance for doubtful accounts of $1,731,000 a decrease of $15,000 from the $1,746,000 at December 31, 2007. 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 borrowings.

Net cash used by operating activities for the fiscal year ended December 31, 2008, was $4,389,000 compared with net cash provided by operating activities of $382,000 for the comparable 2007 period. Net cash used by operating activities for the 2008 period was primarily attributable to increases in deferred tax benefit and inventory of $2,600,000 and $11,011,000, respectively, partially offset by an increase in accounts payable of $2,394,000 and net income of $6,669,000.

Net cash used by investing activities for the fiscal year ended December 31, 2008 was, $593,000 compared with net cash used by investing activities of $446,000 for the prior comparable 2007 period. The net cash used by investing activities for the 2008 period was primarily related to investment in general purpose equipment and purchase of land in Champaign, Illinois.

Net cash provided by financing activities for the fiscal year ended December 31, 2008, was $4,913,000 compared with net cash used by financing activities of $246,000 for the comparable 2007 period. The net cash provided by financing activities for the 2008 period was due to borrowings under the Company's revolving line of credit and proceeds from exercise of stock options and warrants offset by repayments of long term debt.

At December 31, 2008, the Company had cash and cash equivalents of $214,000. 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 2009 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, 2008 (in 000's):

____________

On June 26, 2007, the Company entered into a credit facility with Keltic and on April 17, 2008, Hudson amended its credit facility with Keltic and secured participation from Bridge to provide for borrowings up to $15,000,000. The facility consists of a revolving line of credit and term loans, which expires on June 20, 2011. Advances under the revolving line of credit are limited to (i) 85% of eligible trade accounts receivable and (ii) 55% of eligible inventory. Advances available to Hudson under the A and B term loans may not exceed $2,500,000 and $4,500,000, respectively. At December 31, 2008, the facility bore interest at 6.5%. Substantially all of Hudson's assets are pledged as collateral for its obligations to Keltic and Bridge under the credit facility. In addition, among other things, the agreement restricts Hudson's ability to declare or pay any cash dividends on its capital stock. As of December 31, 2008, Hudson had in the aggregate $7,373,000 of borrowings outstanding and $2,127,000 available for borrowing under the revolving line of credit. In addition, as of December 31, 2008, the Company had $5,500,000 of borrowings outstanding under the A and B term loans with Keltic and Bridge.

In connection with the amendment to the credit facility, the Company issued 66,667 five-year common stock purchase warrants to Keltic exercisable at $1.88 per share, and issued 33,333 five-year common stock purchase warrants to Bridge exercisable at $1.88 per share. The fair value of the warrants was $74,000 and such amount is amortized over the life of the credit facility.

On June 28, 2007, the Company purchased and retired approximately 5,700,000 shares of its common stock from the Fleming Funds at a purchase price of $0.65 per share, for total consideration of approximately $3,700,000. Additionally, certain members of the Company's management, in separate private transactions, purchased approximately 9,200,000 shares of the Company's common stock from the Fleming Funds at a purchase price of $0.65 per share, for a total consideration of approximately $6,000,000. The shares

purchased by management are unregistered shares and management did not receive registration rights in connection with their purchase of their shares.

On June 29, 2007 the Company commenced a tender offer to all of its common shareholders to purchase and retire up to approximately 1,200,000 shares of its common stock at a purchase price of $1.12 per share. Upon completion of the tender offer, a total of approximately 55,000 shares of the Company's common stock, at an aggregate purchase price of approximately $62,000, were tendered to and accepted for purchase by the Company, all of which were retired. On September 25, 2007 the Company utilized the unused tender offer funds to purchase and retire approximately 1,100,000 shares of its common stock from the Fleming Funds at a price of $1.12 per share, for a total consideration of approximately $1,200,000.

As a consequence of the shares purchased by the Company in the tender offer, and the shares purchased by the Company from the Fleming Funds, in 2007 the Company retired an aggregate of approximately 6,900,000 shares of its common stock and has increased its long-term debt by approximately $5,000,000. The retirement of those shares represents more than a 26% reduction in the number of outstanding shares of the Company when compared to the total outstanding shares prior to the tender offer and the purchases from the Fleming Funds.

In May 2005, the Company purchased its Champaign, Illinois facility for a total purchase price of $999,999. The Company 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%.

In April 2008, the Company purchased approximately 5 acres of vacant land immediately adjacent to its Champaign, Illinois facility for a total purchase price of $300,000. The Company financed the purchase with a 15 year amortizing loan in the amount of $300,000 with a balloon payment due on June 1, 2012. The note bears interest at the fixed rate of 6.7% over the entire term of the note.

The Company believes that it will be able to satisfy its working capital requirements for the foreseeable future 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 has not historically had a material impact on the Company's operations.

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, 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, which are the most widely used 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, 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. The limitations imposed by and under the Act, may limit supplies of virgin refrigerants for the foreseeable future or cause a significant increase in the price of virgin HCFC refrigerants. 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.

For the year ended December 31, 2008, no one customer accounted for more than 10% of the Company's revenues. For the year ended December 31, 2007, one customer accounted for approximately 12% 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.

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 and non 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.

In September 2006, the Financial Accounting Standard Board ("FASB") issued FASB statement No. 157 ("SFAS No. 157,") "Fair Value Measurements," which establishes a framework for measuring fair value in generally accepted accounting principles and expands disclosures about fair value measurements. SFAS No. 157 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. SFAS No. 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007, and interim periods within those fiscal years. The FASB agreed to defer the effective date of SFAS No.157 for one year for non-financial assets and non-financial liabilities that are recognized or disclosed at fair value in the financial statements on a nonrecurring basis. There is no deferral for financial assets and financial liabilities, nor for the rare non-financial assets and non-financial liabilities that are remeasured at fair value at least annually.  The adoption of SFAS No. 157 did not have a material impact on the Company's results of operations or its financial position. We are currently evaluating the impact that SFAS No. 157 will have on our non-financial assets and liabilities, but we do not expect the adoption to have a material impact on our financial statements.

In February 2007, the FASB issued SFAS No. 159, "The Fair Value Option for Financial Assets and Financial Liabilities" ("SFAS 159"), which provides companies with an option to report selected financial assets and liabilities at fair value with the changes in fair value recognized in earnings at each subsequent reporting date. SFAS 159 provides an opportunity to mitigate potential volatility in earnings caused by measuring related assets and liabilities differently, and it may reduce the need for applying complex hedge accounting provisions. SFAS 159 is effective for fiscal years beginning after November 15, 2007. Adoption of SFAS 159 had no financial statement impact on the Company.

In December 2007, the FASB issued Statement No. 141 (revised 2007), "Business Combinations" ("FAS 141"). FAS No. 141 (revised 2007) requires an acquirer to measure the identifiable assets acquired, the liabilities assumed and any noncontrolling interest in the acquiree at their fair values on the acquisition date, with the goodwill being the excess value over the net identifiable assets acquired. This standard also requires the fair value measurement of certain other assets and liabilities related to the acquisition such as contingencies. FAS 141 (revised 2007) applies prospectively to business combinations and is effective for fiscal years beginning on or after December 15, 2008.

In June 2008, the Emerging Issues Task Force of the FASB published EITF Issue 07-5 "Determining Whether an Instrument Is Indexed to an Entity's Own Stock" ("EITF 07-5") to address concerns regarding the meaning of "indexed to an entity's own stock" contained in FASB Statement 133 "Accounting for Derivative Instruments and Hedging Activities". This related to the determination of whether a freestanding equity-linked instrument should be classified as equity or debt. If an instrument is classified as debt, it is valued at fair value, and this value is remeasured on an ongoing basis, with changes recorded in earnings in each reporting period. EITF 07-5 is effective for years beginning after December 15, 2008 and earlier adoption is not permitted. Adoption of EITF 07-5 will have no financial statement impact on the Company for warrants that were outstanding on December 31, 2008.

Not applicable.

The financial statements appear in a separate section of this report following Part IV.

None

The Company, under the supervision and with the participation of the Company's management, including the Company's Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of the Company's disclosure controls and procedures, as defined in Rule 13a-15(e) of the Securities Exchange Act or 1934, as amended ("Exchange Act"), as of the end of the period covered by this report. Based on that evaluation, the Chief Executive Officer and the Chief Financial Officer have concluded that the Company's disclosure controls and procedures are effective to ensure that information required to be disclosed in reports filed under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the Securities and Exchange Commission, and that such information is accumulated and communicated to the Company's management, including its principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure. Because of the inherent limitations in all control systems, any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management necessarily is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Furthermore, the Company's controls and procedures can be circumvented by the individual acts of some persons, by collusion of two or more people or by management override of the control, and misstatements due to error or fraud may occur and not be detected on a timely basis.

Management's Report on Internal Control over Financial Reporting.

Management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting for the Company as defined in Rule 13a-15(f) under the Exchange Act. The Company's internal control over financial reporting is designed to provide reasonable assurance to the Company's management and board of directors regarding the preparation and fair presentation of published financial statements and the reliability of financial reporting.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation.

Management assessed the effectiveness of the Company's internal control over financial reporting as of December 31, 2008. In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO") in Internal Control - Integrated Framework. Based on our assessment, we believe that, as of December 31, 2008, the Company's internal control over financial reporting is effective based on those criteria.

This annual report does not include an attestation report of the Company's registered public accounting firm regarding internal control over financial reporting. Management's report was not subject to attestation by the Company's registered public accounting firm pursuant to temporary rules of the Securities and Exchange Commission that permit the Company to provide only management's report in this annual report on Form 10-K.

There were no changes in the Company's internal control over financial reporting, (as defined in Rule 13a-15(f) of the Exchange Act) in the quarter ended December 31, 2008 that materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting.

None

Otto C. Morch has been a Director of the Company since March 1996. Mr. Morch was a Senior Vice President of Commercial Banking at Provident Savings Bank, F.A. for more than five years until his retirement in December 1997.

Hudson has established a Compensation/Stock Option Committee of the Board of Directors, which is responsible for recommending the compensation of our executive officers and for the administration of Hudson's Stock Option Plans. The members of the Committee are Messrs. Abbatecola, Coleman, and Morch.

The By-laws of Hudson provide that the Board of Directors is divided into two classes. Each class is to have a term of two years, with the term of each class expiring in successive years, and is to consist, as nearly as possible, of one-half of the number of directors constituting the entire Board. The By-laws provides for the number of directors to be fixed by the Board of Directors but in any event, shall be no less than five (5) (subject to decrease by a resolution adopted by the shareholders). At Hudson's August 27, 2008, Annual Meeting of the Shareholders, Messrs. Monetta and Zugibe were elected as directors to terms of office that will expire at the Annual Meeting of Shareholders to be held in the year 2010. Messrs. Abbatecola, Coleman and Morch, are currently serving as directors and their terms of office expire at the Annual Meeting of Shareholders to be held in the year 2009.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Exchange Act requires our officers and directors, and persons who own more than 10 percent of a registered class of our equity securities, to file reports of ownership and changes in ownership with the SEC. Officers, directors, and greater than 10 percent shareholders are required by SEC regulation to furnish Hudson with copies of all Section 16(a) forms they file.

Based solely on Hudson's review of copies of such forms received by Hudson, and on representations made to us, we believe that during the year ended December 31, 2008, all filing requirements applicable to all officers directors and greater than 10% beneficial shareholders were complied with, except for one late filing in connection with a stock option exercise by Mr. Coleman.

Code of Conduct and Ethics

We have adopted a written code of conduct and ethics that applies to all directors, and employees, including Hudson's principal executive officer, principal financial officer, principal accounting officer or controller and any persons performing similar functions. We will provide a copy of its code of ethics to any person without charge upon written request addressed to Hudson Technologies, Inc., One Blue Hill Plaza, PO Box 1541, Pearl River, New York 10965, Attention: Stephen P. Mandracchia.

The Company did not issue stock options, or grant any stock awards to any of the named Executives during 2008.

The following tables discloses the outstanding option awards held by the Named Executives as of December 31, 2008. Except as set forth in the following tables, no options were exercised by the Named Executives during the fiscal year ended December 31, 2008. No stock awards have been issued to the Named Executives.

We 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, 2008, we had options outstanding to purchase 59,364 shares of our common stock under the 1994 Plan.

We adopted the 1997 Stock Option Plan (the "1997 Plan") effective June 11, 1997 pursuant to which 2,000,000 shares of our Common stock were reserved for issuance upon the exercise of options designated as either (i) ISOs under the Code, or (ii) nonqualified options. ISOs could be granted under the 1997 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. Stock appreciation rights could also be issued in tandem with stock options. Effective June 11, 2007 our ability to grant options under the 1997 Plan expired.

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, 2008, we had options outstanding to purchase 834,178 shares of our common stock under the 1997 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, under the Code or (ii) non-qualified 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 Hudson. 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 Hudson. 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 Securities Exchange Act of 1934 ("Exchange Act") and is administered by our Compensation/Stock Option Committee of the 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 ISO's granted to a 10% shareholder). 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 of our stock option plans) may not exceed $100,000. Non-qualified 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% shareholder). Except as otherwise provided by the Committee with respect to non-qualified 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, 2008, we had options outstanding to purchase 1,966,301 shares of common stock and 360,000 shares reserved for future issuances under the 2004 Plan.

We have adopted the 2008 Stock Incentive Plan (the "2008 Plan"), pursuant to which 3,000,000 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) non-qualified options, or for issuance upon the granting of restricted stock, deferred stock or other stock-based awards.

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 Hudson. Stock appreciation rights may also be issued in tandem with stock options.

The 2008 Plan is intended to qualify under Rule 16b-3 under the Exchange Act and is administered by our Compensation/Stock Option Committee of the Board of Directors. The Committee, within the limitations of the 2008 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 2008 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 2008 Plan is sooner terminated, the ability to grant options or other awards under the 2008 Plan will expire on June 19, 2018.

Options granted under the 2008 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 ISO's granted to a 10% shareholder). 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 of our stock option plans) may not exceed $100,000. Non-qualified options granted under the 2008 Plan may not be granted at a price less than the fair market value of our common stock. Options granted under the 2008 Plan will expire not more than ten years from the date of grant (five years in the case of ISOs granted to a 10% shareholder). Except as otherwise provided by the Committee with respect to non-qualified options, all options, restricted stock, deferred stock or other stock-based awards granted under the 2008 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, 2008, no options have been issued under the 2008 plan.

Part IV

To Stockholders and Board of Directors

Hudson Technologies, Inc.

Pearl River, New York

We have audited the accompanying consolidated balance sheets of Hudson Technologies, Inc. and subsidiaries as of December 31, 2008 and 2007 and the related consolidated statements of operations, stockholders' equity and cash flows for the years then ended. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the Standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free 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, 2008 and 2007 and the results of their operations and their cash flows for the years then ended in conformity with accounting principles generally accepted in the United States.
