Part I

Item 1. Description of Business

General

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(R) Services performed at a customer's site, consisting of system decontamination to remove moisture, oils and other contaminants and (iii) reclamation of refrigerants. The Company operates through its wholly owned subsidiary Hudson Technologies Company.

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 of refrigerants containing chlorofluorocarbons ("CFCs") and hydrochlorofluorocarbons ("HCFCs"), the most commonly used refrigerants, 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 further requires the recovery of refrigerants used in residential, commercial and industrial air conditioning and refrigeration systems. In addition, the Act prohibited production of CFC refrigerants effective January 1, 1996 and limits the production of refrigerants containing HCFCs, which production is scheduled to be phased out by the year 2030. Owners, operators and companies servicing cooling equipment are responsible for the integrity of their systems regardless of the refrigerant being used and for the responsible management of their refrigerant.

Products and Services

RefrigerantSide(R) Services

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

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 refrigerants are purchased by the Company from several suppliers, including E.I. DuPont de Nemours and Company ("DuPont") as part of the Company's strategic alliance with DuPont (see "Strategic Alliance" below), and resold by the Company, typically at wholesale. In addition, the Company regularly purchases used or contaminated refrigerants from many different sources, which refrigerants are then reclaimed, using the Company's high volume proprietary reclamation equipment, and resold by the Company.

Refrigerant Management Services

The Company provides a complete offering of refrigerant management services, which primarily include reclamation of refrigerants, testing 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:

Baltimore, Maryland            --RefrigerantSide(R) Service depot
Baton Rouge, Louisiana         --RefrigerantSide(R) Service depot
Charlotte, North Carolina      --Reclamation center and RefrigerantSide(R)
                                 Service depot
Chicago, Illinois              --RefrigerantSide(R) Service depot
Fort Myers, Florida            --Engineering center

                                 and RefrigerantSide(R)Service depot
Seattle, Washington            --RefrigerantSide(R) Service depot

Strategic Alliance

In January 1997, the Company entered into agreements with DuPont, pursuant to which the Company (i) provides recovery, reclamation, separation, packaging and testing services directly to DuPont for marketing through DuPont's Authorized Distributor Network and (ii) markets DuPont's SUVA(TM) refrigerant products together with the Company's reclamation and refrigerant management services. These agreements provide for automatic annual renewal subject to termination by either party.

Suppliers

The Company's financial performance is in part dependent on its ability to obtain sufficient quantities of virgin and reclaimable 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. Most of the Company's refrigerant sales are CFC based refrigerants, which are no longer manufactured. To the extent that the Company is unable to source the CFC based refrigerants or virgin refrigerants, 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, 2002, one customer accounted for 11% of the Company's revenues. For the year ended December 31, 2001, one customer accounted for 15% 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.

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).

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(R) Services and other on-site services) and price (particularly with respect to refrigerant sales).

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

Hudson's RefrigerantSide(R) 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 and as a result there can be no assurance that the Company will be able to compete successfully or penetrate this service market as rapidly as it anticipates.

4

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. There can be no assurance that such insurance will be sufficient to cover potential claims or that an adequate level of coverage will be available in the future at a reasonable cost. The Company attempts to operate in a professional and prudent manner and to reduce potential liability risks through specific risk management efforts, including employee training. Nevertheless, 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 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. There can be no assurance that the Company will not face claims resulting in substantial liability for which the Company is uninsured, or that the Company will not incur liability for environmental impairment or personal injury.

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 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 Air Conditioning and Refrigeration Institute ("ARI") prior to resale to a person other than the owner of the equipment from which it was recovered. The ARI and the EPA administer certification programs pursuant to which applicants are certified to reclaim refrigerants in compliance with ARI standards. Under such programs, the ARI issues a certification for each refrigerant and conducts periodic inspections and quality testing of reclaimed refrigerants.

The Company has obtained ARI certification for most refrigerants at each of its reclamation facilities, and is certified by the EPA. In order to maintain ARI certification, the Company is required, among other things, to submit periodic reports to the ARI and pay annual fees based on the number of pounds of refrigerants reclaimed by the Company. However, certification by the ARI is not required.

During February 1996, the EPA published proposed regulations, which, if enacted, would require participation in third-party certification programs similar to the ARI program. Such proposed regulations would also require laboratories designed to test refrigerant purity to undergo a certification process. Extensive comments to these proposed regulations were received by the EPA. The EPA is still considering these comments and no further or additional regulations have been proposed or published.

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 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.

5

The Resource Conservation and Recovery Act of 1976 ("RCRA") requires that facilities that treat, store or dispose of hazardous wastes 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 of Emergency and Hazardous Chemical Inventories (Tier II reports) to the various states in which the Company operates and to file annual Toxic Chemical Release Inventory Forms with the EPA. The Company believes that it has been and remains in full compliance with these requirements.

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, which 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 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 business operations. However, amendments to existing statutes and regulations or adoptions of new statutes and regulations which affect the marketing and sale of refrigerants and services could require the Company to continually adapt its methods of operations and/or discontinue the sale of certain products and services and such changes could result in substantial costs. There can be no assurance that Hudson will be able to continue to comply with applicable laws, regulations and licensing requirements and any future changes. Failure to comply could subject the Company to civil remedies, substantial fines, penalties, injunction, or criminal sanctions, which, alone or in the aggregate could have a material adverse effect on the Company.

Quality Assurance & Environmental Compliance

The Company utilizes in-house quality and regulatory compliance control procedures. Hudson maintains its own analytical testing laboratories 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 three persons engaged full-time in quality control and to monitor the Company's operations for regulatory compliance.

Employees

The Company has 85 full and 5 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 a United States patent relating to the high-speed equipment, components and process to reclaim refrigerants, and a registered trademark for its "Zugibeast(R)". The patent expires in January 2012. The Company believes that patent protection is important to its business and has received additional United States patents relating to high-speed refrigerant recovery and to various RefrigerantSide(R) Services. 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 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, 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.

6

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.

Item 3. Legal Proceedings

In June 1998, United Water of New York Inc. ("United") commenced an action against the Company in the Supreme Court of the State of New York, Rockland County, seeking damages in the amount of $1.2 million allegedly sustained as a result of alleged contamination of certain of United's wells which are in close proximity to the Company's Hillburn, New York facility.

On April 1, 1999, the Company reported a release at the Company's Hillburn, New York facility of approximately 7,800 lbs. of R-11, as a result of a failed hose connection to one of the Company's outdoor storage tanks allowing 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 at the Company's Hillburn facility to remove R-11 levels in the groundwater under and around the Company's facility. The cost of this remediation system was $100,000.

In July 1999, United amended its complaint in the Rockland County action to allege facts relating to, and to seek damages allegedly resulting from the April 1, 1999 R-11 release.

In June 2000, the Rockland County Supreme Court approved a settlement of the Rockland County action commenced by United. Under the settlement, the Company paid to United the sum of $1,000,000 and has been making additional monthly payments in the amount of $5,000, which payments will continue through December 2003. The proceeds of the settlement were required to be used to fund the construction and operation by United of a new remediation tower, as well as for the continuation of temporary remedial measures implemented by United that have successfully contained the spread of R-11. The remediation tower was completed in March 2001, and is designed to treat all of United's impacted wells and restore the water to New York State drinking water standards for supply to the public. The Company carries $1,000,000 of pollution liability insurance per occurrence and in connection with the settlement, exhausted all insurance proceeds available for that occurrence under all applicable policies.

In June 2000, the Company signed an Order on Consent with the DEC regarding all past contamination of the United well field, whereby, the Company agreed to continue operating the remediation system it installed at its Hillburn facility in May 1999, until remaining groundwater contamination has been effectively abated. In May 2001, the Company signed an amendment to the Order on Consent with the DEC, pursuant to which the Company installed one additional monitoring well and modified the Company's existing remediation system to incorporate a second recovery well. The Company is continuing to operate the remediation system.

In May 2000, the Company's Hillburn facility was nominated by the United States Environmental Protection Agency ("EPA") for listing on the National Priorities List ("NPL"), pursuant to the Comprehensive Environmental Response, Compensation and Liability Act of 1980. The Company believes that the agreements reached with the DEC and United Water, together with the reduced levels of contamination present in the United Water wells, make such listing unnecessary and counterproductive. Hudson submitted opposition to the listing within the sixty-day comment period. To date, no final decision has been made by the EPA regarding the proposed listing.

In October 2001, the Company learned that trace levels of R-11 were detected in one of United's wells that is closest to the Village of Suffern's ("Village") well system. During February 2002, the Village expressed concern over the possibility of R-11 reaching its well system and has advised the Company that it was investigating available options to protect its well system. No contamination of R-11 has ever been detected in any of the Village's wells and, as of October 2002, the level of R-11 in the United well closest to the Village was below 1 ppb. In October, 2002 the Village advised the Company it intends to proceed with plans to protect its wells and could look to the Company to reimburse the Village for any costs it may incur. To date, no detailed cost estimate, formal demand or claim has been presented by the Village, however, to the extent the Village proceeds with its plans, the Company may incur additional costs. The Company has agreed to reimburse the Village for approximately $10,000 of costs incurred to date for additional sampling by the Village of its wells and for minor preparatory work in connection with the Village's plan for protecting its wells. The Company continues to work with the Village, and all applicable governmental agencies, to prevent contamination of Village's wells and its water supply.

In February 2003, the Company agreed to extend the statute of limitations applicable to any claims that may be available to Ramapo Land Company, the lessor of the Hillburn facility, arising out of the April 1, 1999 incident for an additional two years. To date, no claims against the Company have been asserted or threatened by Ramapo Land Company.

During the year ended December 31, 2002, the Company recognized $115,000 in additional remediation costs in connection with these matters. There can be no assurance that the R-11 will not spread beyond the United Water well system and impact the Village of Suffern's wells, or that the ultimate outcome of such a spread of contamination will not have a material adverse effect on the Company's financial condition and results of operations. There can be no assurance that the Company's opposition to the EPA's listing of the Company's Hillburn facility on the NPL will be successful, 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. Furthermore, there can be no assurance that Ramapo Land Company will not assert any claim against the Company, or that any such claim will not have a material adverse effect on the Company's financial condition and results of operations.

Part II

Item 5. Market for the Common Equity and Related Stockholder Matters

The Company's Common Stock traded from November 1, 1994 to September 20, 1995 on the NASDAQ Small-Cap Market under the symbol 'HDSN'. From September 20, 1995 through May 12, 2002, the Common Stock traded on the NASDAQ National Market. Since May 13, 2002 the Common Stock has traded on the NASDAQ Small-Cap Market. There can be no assurance that, in the future, the Company will be able to meet the requirements necessary for continued listing of its common stock on NASDAQ Small Cap Market. The following table sets forth, for the periods indicated the range of the high and low sale prices for the Common Stock as reported by NASDAQ.

The number of record holders of the Company's Common Stock was approximately 250 as of March 1, 2003. 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 in the foreseeable future. In addition, the Company has a credit facility with CIT Group/Business Credit, Inc. ("CIT") which, among other things, restricts the Company's ability to declare or pay any dividends on its capital stock. The Company has obtained a waiver from CIT to permit the payment of dividends on its Series A Preferred Stock. The Series A Preferred Stock carries a dividend rate of 7% and as such has a dividend preference over the common stock. The Company pays dividends, in arrears, on the Series A Preferred Stock, semi annually, either in cash or additional shares, at the Company's option (see Item 6 "Management's Discussion and Analysis of Financial Condition and Results of Operations" - Liquidity and Capital Resources).

In November 2002, the Company consummated the private sale of unsecured 12% subordinated promissory notes ("Bridge Notes") to a limited number of purchasers, for which it received gross proceeds of $655,000. The Bridge Notes were for a term of one year and were subordinate in payment to the Company's obligations under its credit facility with CIT. In accordance with the terms of the Bridge Notes, each of the purchasers, at their option, elected to defer quarterly interest payments which were to be added to the principal amount of the Bridge Notes as of each interest payment date and which accrued interest would, in turn, accrue interest at 12% per annum. The Bridge Notes automatically exchanged for unsecured convertible subordinated promissory notes, described in more detail immediately below, ("Exchange Notes") upon approval of such exchange by the Company's shareholders, which approval was obtained at the annual meeting on December 20, 2002.

Effective December 2002, the Company consummated the private sale of unsecured 10% convertible subordinated promissory notes ("Convertible Notes"), to a limited number of purchasers, for which it received gross proceeds of $495,000. At or about the same time, the Bridge Notes were cancelled and exchanged for the Exchange Notes in a principal amount equal to the outstanding principal amount of the Bridge Notes immediately prior to the exchange together with accrued and unpaid interest thereon. As of December 2002, the Exchange Notes and the Convertible Notes were identical in terms and together are referred to herein as the ("Notes"). The Notes have a term of two years and earn interest at an annual rate of 10% payable quarterly in arrears. Holders of the Notes had the one time option to elect to either receive payments of interest on a quarterly basis, subject to the limitations described below, or defer quarterly interest payments, in which case, interest would be added to the outstanding amount of the Notes on each quarterly payment date and accrue interest at the then effective Notes interest rate. The Notes are unsecured and subordinate in payment to the Company's obligations under its credit facility with CIT. The Notes may not be prepaid in cash by the Company without the prior consent of CIT and payment of interest, if any, in cash on any scheduled quarterly interest payment date is limited to an aggregate of $20,000 per calendar year. Holders of the Notes have the right to convert all or a portion of the outstanding principal balance, and any

10

accrued interest thereon, to Common Stock of the Company, upon, but not prior to, the first anniversary of the issuance of the Notes at the conversion rate of $.79 per share (the average closing sale price of the Company's Common Stock as reported on the NASDAQ Small Cap Market for the five business days immediately preceding the issuance of the Notes), subject to certain anti-dilution adjustments (the "Conversion Rate").

In the event of a public offering of equity securities ("Equity Offering") by the Company at any time prior to the first anniversary of the issuance of the Notes, for gross proceeds of not less than $2 million (inclusive of the application of all outstanding principal and interest of the Notes), all outstanding principal and interest, if any, on the Notes shall be either (i) applied to the purchase of equity securities in the Equity Offering at the public offering purchase price, or (ii) converted into restricted shares of Common Stock at the then effective Conversion Rate. Holders of the Notes have the right to determine, to the extent that securities are legally available for purchase in the Equity Offering, whether to apply the Notes to acquire equity securities or convert the Notes into Common Stock; provided, however, that in the event that all or a portion of outstanding principal and interest, if any, of the Notes exceeds the number of equity securities available in the Equity Offering, the balance of the Notes not applied to the purchase of equity securities will be converted into restricted shares of Common Stock at the then-effective Conversion Rate.

The Conversion Rate of the Notes is subject to adjustment on a full ratchet basis (i.e., if the Company issues any stock at a price less than the Conversion Rate, the Conversion Rate for all shares issuable upon conversion of the Notes will be adjusted downward to such price) in certain events including the Company's issuance of Common Stock, warrants or rights to purchase Common Stock (except for shares subject to stock options under or reserved for option grants under any shareholder approved Stock Option Plan or upon exercise or conversion of options, warrants or other exercisable or exchangeable equity or debt securities outstanding immediately prior to the issuance of the Notes) or securities convertible into Common Stock in each case for a consideration per share which is less than the then-effective Conversion Rate. In addition, the Conversion Rate is subject to an appropriate adjustment in the event of: (i) any subdivisions, combinations and reclassifications of the Company's Common Stock;
(ii) any payment, issuance or distribution by the Company to its stockholders of a stock dividend; (iii) the consolidation or merger of the Company with or into another corporation whereby the Company is not the surviving entity; or (iv) the sale by the Company of substantially all of its assets.

In April 2003, holders of the Convertible Notes holding an aggregate principal amount of $495,000 entered into agreements with the Company whereby the holders agreed to modify the Conversion Rate of their Convertible Notes to $1.13 (the average closing sale price of the Company's Common Stock as reported on the NASDAQ Small Cap Market for the five business days immediately preceding the execution of the modification agreements) (the "Modified Conversion Rate"); provided further, that, in the event of an Equity Offering by the Company prior to the first anniversary of the issuance of the Convertible Notes, at a public offering price (which includes the exercise price of stock purchase rights offered in the Equity Offering) below the Modified Conversion Rate but in excess of $.79, the Conversion Rate of the Convertible Notes will be adjusted to not less than the public offering price.

The Company is obligated to issue to the holders of the Notes, on the earlier of
(a) December 20, 2003, or (b) the consummation by the Company of an Equity Offering, Common Stock purchase warrants (the "Note Warrants") to purchase an aggregate number of shares of Common Stock equal to 10% of the number of shares of Common Stock into which the Notes were convertible at December 20, 2002. Each Note Warrant will be exercisable to purchase one share of Common Stock for a period of five years from issuance at an exercise price (the "Exercise Price") equal to 110% of the lesser of (i) the Conversion Price of the Notes as of December 20, 2002, or (ii) the Conversion Price of the Notes on the date of issuance of the Note Warrants. The Exercise Price of the Note Warrants will be subject to anti-dilution adjustment on terms substantially similar to the anti-dilution adjustment of the Conversion Rate of the Notes. As of December 20, 2002, the Company has recognized an original issue discount of $220,000, in connection with the issuance of the Note Warrants.

The Bridge Notes and the Notes were issued by the Company in reliance on Section 4(2) of the Securities Act of 1933, as amended (the "Securities Act") and upon Regulation D promulgated thereunder. In relying upon such exemption (i) the Company did not engage in any "general solicitation" and (ii) each of the purchasers represented that (a) it was either an "accredited investor" as defined in Rule 501 promulgated under the Securities Act, or otherwise met the Company's investor suitability standard, (b) it was capable of evaluating the merits and risks of an investment in the Bridge Notes and the Notes, (c) it was acquiring the Bridge Notes and the Notes for its own account and not with a view to, or for resale in connection with, any distribution within the meaning of the Securities Act, in violation of the Securities Act, and (d) it was provided with access to all necessary information to enable it to evaluate the financial risk inherent in the transaction.

See Item 11 for certain information with respect to the Company's equity compensation plans in effect at December 31, 2002.

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 markets for refrigerants (including unfavorable market conditions adversely affecting the demand for, and the price of refrigerants), regulatory and economic factors, seasonality, competition, litigation, the nature of supplier or customer arrangements which 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 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 judgements, 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 judgements and estimations there could be a material adverse effect on the Company. On an on-going basis, the Company evaluates its estimates, including, but not limited to, those estimates related to its allowance for doubtful accounts, inventories 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. 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

Over the past few years, the Company has been attempting to grow its service revenues through the development of a service offering known as RefrigerantSide(R) Services. RefrigerantSide(R) 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(R) Services to facilitate the growth and development of its service offerings.

During 1999 and 2001 the Company completed sales of its Series A Preferred Stock. The net proceeds of these sales were used to expand the Company's service offering through a network of service depots and to provide working capital. Management believes that its RefrigerantSide(R) Services represent the Company's long term growth potential. However, in recent periods the Company has not been successful in growing its RefrigerantSide(R) Service revenue. As part of the Company's goal to grow its RefrigerantSide(R) Service business, in 2002, the Company commenced a restructuring of its sales and marketing efforts including hiring a new Vice President of Sales and Marketing. In the near term, the Company expects that it will incur additional expenses and losses related to the development of its RefrigerantSide(R) Services. In addition, to the extent that the network of service depots does not develop to expected operating levels, the Company may terminate the operations of certain of its service depots.

Sales of refrigerants continue to represent a majority of the Company's revenues. Most of the Company's refrigerant sales are Chlorofluorocarbon ("CFC") based refrigerants, which are no longer manufactured. In addition, the Company expects that, over time, the demand for CFC based refrigerants will decrease as equipment that utilizes other chemical based refrigerants replaces those units that utilize CFC based refrigerants. However, to the extent that the Company is unable to source CFC based refrigerants on commercially reasonable terms or at all, or the demand for CFC based refrigerants decreases, the Company's financial condition and

12

results of operations would be materially adversely affected. In addition, the Company's long-term strategy of growth in revenues generated from RefrigerantSide(R) Services may cause reductions in revenues derived from the sale of refrigerants.

The Company believes that, for the foreseeable future in the refrigeration industry overall, there will be a trend towards lower sales prices, volumes and gross profit margins on refrigerant sales, which may result in an adverse effect on the Company's operating results. In addition, to the extent that the Company 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 effect on its operating results.

Results of Operations

Year ended December 31, 2002 as compared to year ended December 31, 2001

Revenues for 2002 were $19,963,000, a decrease of $805,000 or 4% from the $20,768,000 reported during the comparable 2001 period. The decrease in revenues was primarily attributable to a decrease in refrigerant revenues and a decrease in RefrigerantSide(R) Services revenues. The decrease in refrigerant revenues is related to a reduction in the sales prices per pound for certain refrigerants. The decrease in RefrigerantSide(R) Services was primarily a reduction in the number of jobs sold.

Cost of sales for 2002 was $14,505,000, a decrease of $466,000 or 3% from the $14,971,000 reported during the comparable 2001 period. The decrease in cost of sales was primarily due to a reduction in payroll and supply costs associated with the Company's RefrigerantSide(R) Services offset by an increase in cost of refrigerant. As a percentage of sales, cost of sales were 73% of revenues for 2002, an increase from the 72% reported for the comparable 2001 period. The increase in cost of sales as a percentage of revenues was primarily attributable to an increase in the cost of refrigerant sold.

Operating expenses for 2002 were $7,911,000 a decrease of $106,000 or 1% from the $8,017,000 reported during the comparable 2001 period. The decrease was primarily attributable to a reduction in administrative payroll costs and a reduction in depreciation and amortization offset by an increase in marketing and sales payroll costs of $233,000 associated with the Company's RefrigerantSide(R) Service offering.

Other income (expense) for 2002 was $(69,000), compared to the $(179,000) reported during the comparable 2001 period. Other income (expense) includes interest expense of $347,000 and $423,000 for 2002 and 2001, respectively, offset by other income of $278,000 and $244,000 for 2002 and 2001, respectively. The decrease in interest expense is primarily attributed to a decrease in outstanding indebtedness and interest rates during 2002 as compared to 2001. Other income primarily relates to interest income and proceeds from the prepayment of the note receivable from Environmental Support Solutions, Inc. ("ESS").

No income taxes for the years ended December 31, 2002 and 2001 were recognized. The Company recognized a reserve allowance against the deferred tax benefit for the 2002 and 2001 losses. The tax benefits associated with the Company's net operating loss carry forwards would be recognized to the extent that the Company recognizes net income in future periods. A portion of the Company's net operating loss carry forwards are subject to annual limitations (see Note 4 to the Notes to the Consolidated Financial Statements).

Net loss for 2002 was $2,522,000 an increase of $123,000 or 5% from the $2,399,000 net loss reported during the comparable 2001 period. The increase in net loss was primarily attributable to a decrease in revenues resulting from lower sales prices of certain refrigerants sold as well as an increase in the cost of the refrigerant that was sold, offset by the non-recurring gain of $232,000 from the prepayment of the note receivable from ESS.

Liquidity and Capital Resources

At December 31, 2002, the Company had a working capital deficit of approximately $128,000, a decrease of $1,055,000 from working capital of $927,000 at December 31, 2001. The decrease in working capital is primarily attributable to the net loss incurred during the year ended December 31, 2002 offset by proceeds from the sale of Bridge Notes and Convertible Notes to purchasers including certain officers and the Series A Preferred Stockholders.

Principal components of current assets are inventory and trade receivables. At December 31, 2002, the Company had inventories of $2,967,000, an increase of $580,000 or 24% from the $2,387,000 at December 31, 2001. 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 (see "Seasonality and Fluctuations in Operating Results"). At December 31, 2002, the Company had trade receivables of $1,971,000, a decrease of $774,000 or 28% from the $2,745,000 at December 31, 2001. 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.

13

The Company has historically financed its working capital requirements through cash flows from operations, the issuance of debt and equity securities, bank and related party borrowings. In recent years the Company has not financed its working capital requirements through cash flows from operations but rather from issuances of equity securities and bank borrowings. In order for the Company to finance its working capital requirements through cash flows from operations the Company must reduce its operating losses. There can be no assurances that the Company will be successful in lowering its operating losses, in which case the Company will be required to fund its working capital requirements from additional issuances of equity securities and/or additional bank borrowings. Based on the current investment environment there can be no assurances that the Company would be successful in raising additional capital. The inability to raise additional capital could have a material adverse effect on the Company. Furthermore, the inability of the Company to renew or replace its existing credit facility with The CIT Group/Business Credit, Inc. ("CIT") at the expiration of the term of the current facility on April 29, 2003 would have a material adverse effect on the Company's operations and financial condition.

Net cash used by operating activities for the year ended December 31, 2002, was $1,342,000 compared with net cash used by operating activities of $2,361,000 for the comparable 2001 period. Net cash used by operating activities was primarily attributable to the net loss for the 2002 period and an increase in inventories offset by a reduction in trade receivables.

Net cash used by investing activities for the year ended December 31, 2002, was $80,000 compared with net cash provided by investing activities of $554,000 for the prior comparable 2001 period. The net cash used by investing activities was due to equipment additions primarily associated with the Company's depot network.

Net cash provided by financing activities for the year ended December 31, 2002, was $585,000 compared with net cash provided by financing activities of $2,326,000 for the comparable 2001 period. The net cash provided by financing activities for the 2002 period primarily consisted of $1,150,000 aggregate proceeds received by the Company from the sale of Bridge Notes and Convertible Notes to purchasers including the holders of the Company's Series A Preferred Stock and certain officers and certain members of their family, offset by the repayment of long term debt of $788,000.

At December 31, 2002, the Company had cash and cash equivalents of $545,000. 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 associated with its RefrigerantSide(R)Service offering and consolidation of its reclamation facilities. The Company estimates that capital expenditures during 2003 may range from approximately $500,000 to $700,000.

The following is a summary of the Company's significant contractual cash obligations for the periods indicated that existed as of December 31, 2002 and is more fully disclosed in the Notes to Consolidated Financial Statements (see Notes 9 and 11 to the Notes of the Consolidated Financial Statements included in this report on Form 10-KSB) (amounts in thousands of dollars).

The Company has entered into a credit facility with CIT, which provides for borrowings to the Company of up to $6,500,000. The facility requires minimum borrowings of $1,250,000. The facility provides for a revolving line of credit and a term loan. Advances under the revolving line of credit are limited to (i) 80% of eligible trade accounts receivable and (ii) 50% of eligible inventory (which inventory amount shall not exceed 200% of eligible trade accounts receivable or $3,250,000). As of December 31, 2002, the Company had availability under its revolving line of credit of approximately $292,000. Advances available to the Company under the term loan are based on existing fixed asset valuations and future advances under the term loan of up to an additional $1,000,000 are based on future capital expenditures. As of December 31, 2002, the Company had approximately $303,000 outstanding under its term loans and $2,034,000 outstanding under its revolving line of credit and due to the expiration of the credit facility in April 2003, all such amounts are reflected on the Company's December 31, 2002 Balance Sheet as current liabilities. The facility bears interest at the prime rate plus 1.5%, 5.75% at December 31, 2002, and substantially all of the Company's assets are pledged as collateral for obligations to CIT. In addition, among other things, the agreements restrict the Company's ability to declare or pay any dividends on its capital stock. The Company has obtained a waiver from CIT to permit the payment of dividends on its Series A Preferred Stock.

The Company is currently in negotiations with CIT regarding a possible extension of the term of the credit facility or the entering into of a new credit facility, and is also seeking alternate sources of financing. While the Company believes that it will be able to obtain replacement financing, there can be no assurance that CIT will continue to lend funds to the Company after the expiration of the

14

current credit facility or that the Company will be able to obtain financing from another source should CIT decide not to continue providing financing to the Company. However, even if the Company is able to obtain replacement financing it may be on terms that are less favorable to the Company than the current CIT facility. A failure of the Company to obtain adequate financing from CIT or an alternate source after the expiration of the current CIT credit facility would have a material adverse effect on the Company's operations and financial condition. As a result of this uncertainty, the Company's independent auditors have added an explanatory paragraph regarding the Company's ability to continue as a going concern.

Effective March 19, 1999, the Company sold 75% of its stock ownership in ESS to one of ESS's founders. The consideration for the Company's sale of its interest was $100,000 in cash and a six-year 6% interest bearing note in the amount of $380,000. The Company has recognized as income the portion of the proceeds associated with the note receivable upon the receipt of cash. This sale did not have a material effect on the Company's financial condition or results of operations. Effective October 11, 1999, the Company sold to three of ESS's employees an additional 5.4% ownership in ESS. The Company received $37,940 from the sale of this additional ESS stock. Effective April 18, 2000, ESS redeemed the balance of the Company's stock ownership in ESS. The Company received cash in the amount of $188,000 from the redemption. Pursuant to an agreement dated January 22, 2002, ESS and the Company agreed to a 16% discount of the outstanding balance on the note receivable. On January 25, 2002, as part of a capital financing completed by ESS, ESS paid the Company $231,951, representing the discounted balance as of that date, as full satisfaction of the note receivable and as of that date the Company recognized the proceeds as other income.

In November 2002, the Company consummated the private sale of Bridge Notes to a limited number of purchasers, for which it received gross proceeds of $655,000. The Bridge Notes were for a term of one year and were subordinate in payment to the Company's obligations under its credit facility with CIT. In accordance with the terms of the Bridge Notes, each of the purchasers, at their option, elected to defer quarterly interest payments which were to be added to the principal amount of the Bridge Notes as of each interest payment date and which accrued interest would, in turn, accrue interest at 12% per annum. The Bridge Notes automatically exchanged for the Exchange Notes, upon approval of such exchange by the Company's shareholders, which approval was obtained at the annual meeting on December 20, 2002.

Effective December 2002, the Company consummated the private sale of Convertible Notes to a limited number of purchasers, for which it received gross proceeds of $495,000. At or about the same time, the Bridge Notes were cancelled and exchanged for the Exchange Notes in a principal amount equal to the outstanding principal amount of the Bridge Notes immediately prior to the exchange together with accrued and unpaid interest thereon. The Notes have a term of two years and earn interest at an annual rate of 10% payable quarterly in arrears. Holders of the Notes had the one time option to elect to either receive payments of interest on a quarterly basis, subject to limitations described below, or defer quarterly interest payments, in which case, interest would be added to the outstanding amount of the Notes on each quarterly payment date and accrue interest at the then effective Notes interest rate. The Notes are unsecured and subordinate in payment to the Company's obligations under its credit facility with CIT. The Notes may not be prepaid in cash by the Company without the prior consent of CIT and payment of interest, if any, in cash on any scheduled quarterly interest payment date is limited to an aggregate of $20,000 per calendar year. Holders of the Notes have the right to convert all or a portion of the outstanding principal balance, and any accrued interest thereon, to Common Stock of the Company, upon, but not prior to, the first anniversary of the issuance of the Notes at the Conversion Rate of $.79 per share.

In the event of an Equity Offering by the Company at any time prior to the first anniversary of the issuance of the Notes, for gross proceeds of not less than $2 million (inclusive of the application of all outstanding principal and interest of the Notes), all outstanding principal and interest, if any, on the Notes shall be either (i) applied to the purchase of equity securities in the Equity Offering at the public offering purchase price, or (ii) converted into restricted shares of Common Stock at the then effective Conversion Rate. Holders of the Notes have the right to determine, to the extent that securities are legally available for purchase in the Equity Offering, whether to apply the Notes to acquire such equity securities sold in the Equity Offering or convert the Notes into Common Stock; provided, however, that in the event that all or a portion of outstanding principal and interest, if any, of the Notes exceeds the number of equity securities available in the Equity Offering, the balance of the Notes not applied to the purchase of equity securities will be converted into restricted shares of Common Stock at the then-effective Conversion Rate.

The Conversion Rate of the Notes is subject to adjustment on a full ratchet basis (i.e., if the Company issues any stock at a price less than the Conversion Rate, the Conversion Rate for all shares issuable upon conversion of the Notes will be adjusted downward to such price) in certain events including the Company's issuance of Common Stock, warrants or rights to purchase Common Stock (except for shares subject to stock options under or reserved for option grants under any shareholder approved Stock Option Plan or upon exercise or conversion of options, warrants or other exercisable or exchangeable equity or debt securities outstanding immediately prior to the issuance of the Notes) or securities convertible into Common Stock in each case for a consideration per share which is less than the then-effective Conversion Rate. In addition, the Conversion Rate is subject to an appropriate adjustment in the event of: (i) any subdivisions, combinations and reclassifications of the Company's Common Stock;
(ii) any payment, issuance or distribution by the Company to its stockholders of a stock dividend; (iii) the consolidation or merger of the Company with or into another corporation whereby the Company is not the surviving entity; or (iv) the sale by the Company of substantially all of its assets.

15

In April 2003, holders of the Convertible Notes holding an aggregate principal amount of $495,000 entered into agreements with the Company whereby the holders agreed to modify the Conversion Rate of their Convertible Notes to the Modified Conversion Rate of $1.13 (the average closing sale price of the Company's Common Stock as reported on the NASDAQ Small Cap Market for the five business days immediately preceding the execution of the modification agreements); provided further, that, in the event of an Equity Offering by the Company prior to the first anniversary of the issuance of the Convertible Notes, at a public offering price (which includes the exercise price of stock purchase rights offered in the Equity Offering) below the Modified Conversion Rate but in excess of $.79, the Conversion Rate of the Notes will be adjusted to not less than the public offering price.

The Company is obligated to issue to the holders of the Notes, on the earlier of
(a) December 20, 2003, or (b) the consummation by the Company of an Equity Offering, Note Warrants to purchase an aggregate number of shares of Common Stock equal to 10% of the number of shares of Common Stock into which the Notes were convertible at December 20, 2002. Each Note Warrant will be exercisable to purchase one share of Common Stock for a period of five years from issuance at an Exercise Price equal to 110% of the lesser of (i) the Conversion Price of the Notes as of December 20, 2002, or (ii) the Conversion Price of the Notes on the date of issuance of the Note Warrants. The Exercise Price of the Note Warrants will be subject to the anti-dilution adjustment on terms substantially similar to anti-dilution adjustment of the Conversion Rate of the Notes. As of December 20, 2002, the Company has recognized an original issue discount of $220,000, in connection with the issuance of the Note Warrants.

On March 30, 1999, the Company completed the sale of 65,000 shares of its Series A Preferred Stock, with a liquidation value of $100 per share, to Fleming US Discovery Fund III, L.P. and Fleming US Discovery Offshore Fund III, L.P. The gross proceeds from the sale of the Series A Preferred Stock were $6,500,000. The Series A Preferred Stock currently converts to Common Stock at a price of $2.375 per share, which was 27% above the closing market price of Common Stock on March 29, 1999.

On February 16, 2001, the Company completed the sale of 30,000 shares of its Series A Preferred Stock, with a liquidation value of $100 per share, to Fleming US Discovery Fund III, L.P. and Fleming US Discovery Offshore Fund III, L.P. The gross proceeds from the sale of the Series A Preferred Stock were $3,000,000. The Series A Preferred Stock currently converts to Common Stock at a price of $2.375 per share, which was 23% above the closing market price of Common Stock on February 15, 2001.

The Series A Preferred Stock provides for anti-dilution adjustment of the conversion price in the event of the subsequent offering by the Company of securities for consideration per share less than the then effective conversion price of the Series A Preferred Stock. At the direction of the Nasdaq Stock Market, Inc., a minimum of $1.78 per share (the "Conversion Price Floor"), below which the conversion price of the Series A Preferred Stock could not be adjusted, had been instituted by the Company and the holders of the Series A Preferred Stock by amendment to the designation of the Series A Preferred Stock, and at the same time the Company agreed not to offer securities for consideration per share less than the Conversion Price Floor without the consent of the holders of the Series A Preferred Stock. Subsequently, in consideration for the consent of the holders of the Series A Preferred Stock to the Company's engagement in the private offering of the Notes at a conversion price below the Conversion Price Floor, the stockholders of the Company, at the annual meeting on December 20, 2002, voted in favor of a proposal to remove the Conversion Price Floor and the designation of the Series A Preferred Stock was amended accordingly. Although the holders of the Series A Preferred Stock agreed to waive their rights to an immediate downward adjustment of the current $2.375 conversion price of the Series A Preferred Stock in connection with the issuance of the Notes, any subsequent conversion of the Notes will result in a downward adjustment of the conversion price of the Series A Preferred Stock to equal the conversion price of the Notes. Consequently, upon conversion of the Exchange Notes at the $.79 per share conversion price the anti-dilution provisions of the Series A Preferred Stock will cause the conversion price of the Series A Preferred Stock to adjust downward to the $.79 per share. Assuming that the Series A Preferred Stock converts to common stock at a conversion price of $.79 per share and based upon 116,629 shares of Series A Preferred Stock issued as of December 31, 2002, the holders of the Series A Preferred Stock would receive 14,763,164 shares of common stock. Similarly, the conversion price of such Series A Preferred Stock may be subsequently adjusted to equal the consideration received by the Company in connection with any subsequent issuance of securities below $2.375.

The Series A Preferred Stock has voting rights on an as-if converted basis. The number of votes applicable to the Series A Preferred Stock is equal to the number of shares of Common Stock into which the Series A Preferred Stock is then convertible. The designation of the Series A Preferred Stock provided for a proxy granted by the holders of the Series A Preferred Stock in favor of certain of the Company's officers to vote all shares of Common Stock into which the Series A Preferred Stock converts (including any additional shares subsequently acquired by such holders) in excess of 29% of the votes entitled to be cast by the Series A Preferred Stock holders. As noted above, in consideration for consent of the holders of the Series A Preferred Stock to the Company's engagement in the private offering of the Notes at a conversion rate below the Conversion Price Floor, the stockholders of the Company, at the annual meeting on December 20, 2002, voted in favor of a proposal to remove the proxy from the designation of the Series A Preferred Stock and the designation of the Series A Preferred Stock was amended accordingly. The Series A Preferred Stock carries a dividend rate of

16

7%, which will increase to 16%, if the stock remains outstanding on or after March 31, 2004. The Company used the net proceeds from the issuance of the Series A Preferred Stock to expand its RefrigerantSide(R) Services business and for working capital purposes.

The Company pays dividends, in arrears, on the Series A Preferred Stock, semi annually, either in cash or additional shares, at the Company's option. On March 30 and September 30, 2002, the Company declared and paid, in-kind, the dividends on the outstanding Series A Preferred Stock and issued 3,873 and 4,011, respectively, additional shares of its Series A Preferred Stock in satisfaction of the dividends due. The Company may redeem the Series A Preferred Stock on March 31, 2004 either in cash or shares of Common Stock valued at 90% of the average trading price of the Common Stock for the 30 days preceding March 31, 2004. In addition, the Company may call the Series A Preferred Stock if the market price of its Common Stock is equal to or greater than 250% of the conversion price and the Common Stock has traded with an average daily volume in excess of 20,000 shares for a period of thirty consecutive days.

The Company has provided certain registration, preemptive and tag along rights to the holders of the Series A Preferred Stock. The holders of the Series A Preferred Stock, voting as a separate class, have the right to elect up to two members to 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 have the right to attend and observe meetings of the Board of Directors. Currently, the holders have elected one member to the Board of Directors.

The Company is continuing to evaluate opportunities to rationalize its operating facilities and its depot network based on ways to reduce costs or to increase revenues. As a result, the Company may discontinue certain operations, eliminate depot and overhead costs and, in doing so, may incur future charges to exit certain operations.

The Company believes that it will be able to satisfy its working capital requirements for the immediate future from anticipated cash flow from operations and available funds under its credit facility with CIT and any replacement facility it enters into after the expiration of the current term of the CIT facility. Although the Company believes it can obtain replacement financing for the CIT facility there can be no assurance that it will do so. Moreover, even if the Company obtains replacement financing for the CIT facility it believes that it will need additional financing during 2003 to support its continuing operations. In addition, 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 depots 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 need to significantly modify its plans or it may require additional capital sooner than anticipated. The Company is currently seeking to obtain additional financing through the issuance of debt and/or equity securities. There can be no assurance that the Company will be able to obtain any additional capital on commercially reasonable terms or at all and its inability to do so would have a material adverse affect on the Company.

Inflation

Inflation has not historically had a material impact on the Company's operations. However, the current and anticipated rising cost of fuel prices will have a negative effect on the Company's purchase price of refrigerants and other products, which will have an adverse effect on the Company's operations.

Reliance on Suppliers and Customers

The Company's financial performance is in part dependent on its ability to obtain sufficient quantities of virgin and reclaimable 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. To the extent that the Company is unable to obtain sufficient quantities of virgin or reclaimable refrigerants in the future, or resell reclaimed refrigerants at a profit, the Company's financial condition and results of operations would be materially adversely affected.

During the year ended December 31, 2002, one customer accounted for 11% of the Company's revenues. During the year ended December 31, 2001, one customer accounted for 15% of the Company's revenues. The loss of a principal customer or a decline in the economic prospects and 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 by domestic users of refrigerants, 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 have resulted in additional losses during the second half of the year. Delays 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. With respect to the Company's RefrigerantSide(R) Services, to date,

17

the Company has not identified any seasonal pattern. However, the Company could experience a similar seasonal element to this portion of its business in the future.

Compliance with Section 16(a) of the Securities Exchange Act

Section 16(a) of the Securities Exchange Act of 1934 requires the Company's officers and directors, and persons who own more than 10 percent of a registered class of the Company's equity securities, to file reports of ownership and changes in ownership with the Securities and Exchange Commission ("SEC"). Officers, directors, and greater than 10 percent stockholders are required by SEC regulation to furnish the Company with copies of all Section 16(a) forms they file.

Based solely on the Company's review of the copies of such forms received by the Company, the Company believes that during the year ended December 31, 2002 all filing requirements applicable to its officers, directors, and greater than 10 percent beneficial stockholders were complied with, except that Mr. Zugibe failed to timely file a Form 4 or 5 with respect to options to purchase 15,000 shares of the Company's Common Stock granted to him in each of April 2002, July 2002 and October 2002.

In addition, commencing in August 1998, non-employee directors receive 5,000 nonqualified stock options per year of service under the Company's Stock Option Plans.

In addition to the standard annual director's remuneration, Mr. Schell receives $20,000 and 5,000 stock options for serving as a director and a consultant to the Company. The additional stock options are issued with an exercise price equal to that of the other directors' option grants.

As of December 31, 2002, the Company has granted to Harry C. Schell nonqualified options to purchase 40,000 shares of Common Stock at exercise prices ranging from $2.38 to $3.00 per share. Such options vested and are fully exercisable as of December 31, 2002. The Company has also granted to each of Dominic J. Monetta, Otto Morch and Vincent Abbatecola, nonqualified options to purchase 20,000 shares of Common Stock at exercise prices ranging from $2.38 to $3.00 per share.

The Company is the beneficiary of a "key-man" insurance policy on the life of Mr. Zugibe in the amount of $1,000,000.

Stock Option Plans

1994 Stock Option Plan

The Company has adopted an Employee Stock Option Plan (the "1994 Plan") effective October 31, 1994 pursuant to which 725,000 shares of Common Stock are currently 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 may be granted under the 1994 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.

The 1994 Plan is intended to qualify under Rule 16b-3 under the Securities Exchange Act of 1934, as amended (the "Exchange Act") and is administered by the Compensation/Stock Option Committee of the Board of Directors. The Committee, within the limitations of the 1994 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 sooner terminated, the 1994 Plan will expire on December 31, 2004.

ISOs granted under the 1994 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). 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 stock option plans of the Company) may not exceed $100,000. Non-qualified options granted under the 1994 Plan may not be granted at a price less than 85% of the market value of the Common Stock on the date of grant. Options granted under the 1994 Plan will 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 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 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, 2002, the Company had options outstanding to purchase 610,000 shares of Common Stock under the 1994 Plan. During 2000, the Company granted options to purchase 40,000 shares each to Kevin J. Zugibe, Stephen P. Mandracchia and Thomas

23

P. Zugibe exercisable at $2.375 per share. Such options vest and are fully exercisable as of August 3, 2000. During 2001, the Company granted options to purchase shares to Kevin J. Zugibe, 50,000 shares; Brian F. Coleman, 20,000 shares; Stephen P. Mandracchia, 15,000 shares; and Thomas P. Zugibe, 20,000 shares, all of which are exercisable at $2.55 per share. Such options vest quarterly in equal amounts over three years, commencing with the first quarter of 2002. In addition, during 2001, in lieu of salary, the Company also granted options to purchase 15,000 shares to Kevin J. Zugibe exercisable at $2.55 per share, all of which vested and are fully exercisable as of December 13, 2001. During 2001, the Company also granted options to purchase 80,000 shares to Brian F. Coleman exercisable at $2.55 per share, all of which vested as of December 13, 2001, and which became exercisable as follows: 39,215 on 12/13/01, 39,215 on 12/13/02 and 1,570 on 12/13/03. In addition, during 2001, the Company also granted options to certain employees to purchase 20,000 shares exercisable at $2.55 per share. Such options vest quarterly in equal amounts over three years, commencing with the first quarter of 2002. During 2002, the Company granted options to purchase 40,000 shares to Neil B. Gafarian exercisable at $2.65 per share. In addition, during 2002, in lieu of salary, the Company granted options to purchase 45,000 shares to Kevin J. Zugibe exercisable at prices ranging from $1.40 to $2.50 per share. All such options vest immediately and become exercisable at various dates through June 2003 (see Note 12 to the Notes of the Consolidated Financial Statements).

1997 Stock Option Plan

The Company has adopted the 1997 Stock Option Plan (the "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. Nonqualified 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.

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 the 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 sooner terminated, 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 persons holding 10% or more of the voting stock of the Company). 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 stock option plans of the Company) 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 persons holding 10% or more of the voting stock of the Company). 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.

Item 12. Certain Relationships and Related Transactions

In the regular course of its business, the Company purchases refrigerants from and sells refrigerants to DuPont and performs recovery, reclamation, RefrigerantSide(R) Services and other services for DuPont. During the years ended December 31, 2002 and 2001, the Company had sales to DuPont in the amount of $974,000 and $1,124,000, respectively (see "Description of Business" - Strategic Alliance).

On February 16, 2001, the Company completed the sale of 30,000 shares of its Series A Preferred Stock, with a liquidation preference of $100 per share, to Fleming US Discovery Fund III, L.P. and Fleming US Discovery Offshore Fund III, L.P. The gross proceeds from the Sale of the Series A Preferred Stock were $3,000,000. Mr. Burr, a director of the Company, has a consulting agreement with J.P. Morgan Partners under which he is the lead partner of Fleming US Discovery Partners, L.P., a private equity sponsor affiliated with J.P. Morgan Chase & Co. Fleming US Discovery Partners, L.P. is the general partner of Fleming US Discovery Fund III, L.P. and Fleming US Discovery Offshore Fund III, L.P.

In November 2002, the Company consummated the private sale of Bridge Notes to certain officers and certain members of their family and the holders of the Series A Preferred Stock, for which it received gross proceeds of $655,000. The Bridge Notes were for a term of one year and were subordinate in payment to the Company's obligations under its credit facility with CIT. In accordance with the terms of the Bridge Notes, each of the purchasers, at their option, elected to defer quarterly interest payments which were to be added to the principal amount of the Bridge Notes as of each interest payment date and which accrued interest would, in turn, accrue interest at 12% per annum. The Bridge Notes automatically exchanged for the Exchange Notes, upon approval of such exchange by the Company's shareholders, which approval was obtained at the annual meeting on December 20, 2002.

Effective December 2002, the Company consummated the private sale of Convertible Notes to certain officers and certain members of their family and the holders of the Series A Preferred Stock, for which it received gross proceeds of $495,000. At or about the same time, the Bridge Notes were cancelled and exchanged for the Exchange Notes in a principal amount equal to the outstanding principal amount of the Bridge Notes immediately prior to the exchange together with accrued and unpaid interest thereon. The Notes have a term of two years and earn interest at an annual rate of 10% payable quarterly in arrears. Holders of the Notes had the one time option to elect to either receive payments of interest on a quarterly basis, subject to the limitations described below, or defer quarterly interest payments, in which case, interest would be added to the outstanding amount of the Notes on each quarterly payment date and accrue interest at the then effective Notes interest rate. The Notes are unsecured and subordinate in payment to the Company's obligations under its credit facility with CIT. The Notes may not be prepaid in cash by the Company without the prior consent of CIT and payment of interest, if any, in cash on any scheduled quarterly interest payment date is limited to an aggregate of $20,000 per calendar year. Holders of the Notes have the right to convert all or a portion of the outstanding principal balance, and any accrued interest thereon, to Common Stock of the Company, upon, but not prior to, the first anniversary of the issuance of the Notes at the Conversion Rate of $.79 per share.

In the event of an Equity Offering by the Company at any time prior to the first anniversary of the issuance of the Notes, for gross proceeds of not less than $2 million (inclusive of the application of all outstanding principal and interest of the Notes), all outstanding principal and interest, if any, on the Notes shall be either (i) applied to the purchase of equity securities in the Equity Offering at the public offering purchase price, or (ii) converted into restricted shares of Common Stock at the then effective Conversion Rate. Holders of the Notes have the right to determine, to the extent that securities are legally available for purchase in the Equity Offering, whether to apply the Notes to acquire such equity securities sold in the Equity Offering or convert the Notes into Common Stock; provided, however, that in the event that all or a portion of outstanding principal and interest, if any, of the Notes exceeds the number of equity securities available in the Equity Offering, the balance of the Notes not applied to the purchase of equity securities will be converted into restricted shares of Common Stock at the then-effective Conversion Rate.

The Conversion Rate of the Notes is subject to adjustment on a full ratchet basis (i.e., if the Company issues any stock at a price less than the Conversion Rate, the Conversion Rate for all shares issuable upon conversion of the Notes will be adjusted downward to such price) in certain events including the Company's issuance of Common Stock, warrants or rights to purchase Common Stock (except for shares subject to stock options under or reserved for option grants under any shareholder approved Stock Option Plan or upon exercise or conversion of options, warrants or other exercisable or exchangeable equity or debt securities outstanding immediately prior to the issuance of the Notes) or securities convertible into Common Stock in each case for a consideration per share which is less than the then-effective Conversion Rate. In addition, the Conversion Rate is subject to an appropriate adjustment in the event of: (i) any subdivisions, combinations and reclassifications of the Company's Common Stock;
(ii) any payment, issuance or distribution by the Company to its stockholders of a stock dividend; (iii) the consolidation or merger of the Company with or into another corporation whereby the Company is not the surviving entity; or (iv) the sale by the Company of substantially all of its assets.

In April 2003, holders of the Convertible Notes holding an aggregate principal amount of $495,000 entered into agreements with the Company whereby the holders agreed to modify the Conversion Rate of their Convertible Notes to the Modified Conversion Rate of

27

$1.13 (the average closing sale price of the Company's Common Stock as reported on the Nasdaq Small Cap Market for the five business days immediately preceding the execution of the modification agreements); provided further, that, in the event of an Equity Offering by the Company prior to the first anniversary of the issuance of the Convertible Notes, at a public offering price (which includes the exercise price of stock purchase rights offered in the Equity Offering) below the Modified Conversion Rate but in excess of $.79, the Conversion Rate of the Notes will be adjusted to not less than the public offering price.

The Company is obligated to issue to the holders of the Notes, on the earlier of
(a) December 20, 2003, or (b) the consummation by the Company of an Equity Offering, Note Warrants to purchase an aggregate number of shares of Common Stock equal to 10% of the number of shares of Common Stock into which the Notes were convertible at December 20, 2002. Each Note Warrant will be exercisable to purchase one share of Common Stock for a period of five years from issuance at an Exercise Price equal to 110% of the lesser of (i) the Conversion Price of the Notes as of December 20, 2002, or (ii) the Conversion Price of the Notes on the date of issuance of the Note Warrants. The Exercise Price of the Note Warrants will be subject to the anti-dilution adjustment on terms substantially similar to anti-dilution adjustment of the Conversion Rate of the Notes. As of December 20, 2002, the Company has recognized an original issue discount of $220,000, in connection with the issuance of the Note Warrants.

The Bridge Notes and the Notes were issued by the Company in reliance on Section 4(2) of the Securities Act and upon Regulation D promulgated thereunder. In relying upon such exemption (i) the Company did not engage in any "general solicitation" and (ii) each of the purchasers represented that (a) it was either an "accredited investor" as defined in Rule 501 promulgated under the Securities Act, or otherwise met the Company's investor suitability standard, (b) it was capable of evaluating the merits and risks of an investment in the Convertible Notes, (c) it was acquiring the Convertible Notes for its own account and not with a view to, or for resale in connection with, any distribution within the meaning of the Securities Act, in violation of the Securities Act, and (d) it was provided with access to all necessary information to enable it to evaluate the financial risk inherent in the transaction.

The Series A Preferred Stock provides for anti-dilution adjustment of the conversion price in the event of the subsequent offering by the Company of securities for consideration per share less than the then effective conversion price of the Series A Preferred Stock. At the direction of the Nasdaq Stock Market, Inc., a minimum of $1.78 per share (the "Conversion Price Floor"), below which the conversion price of the Series A Preferred Stock could not be adjusted, had been instituted by the Company and the holders of the Series A Preferred Stock by amendment to the designation of the Series A Preferred Stock, and at the same time the Company agreed not to offer securities for consideration per share less than the Conversion Price Floor without the consent of the holders of the Series A Preferred Stock. Subsequently, in consideration for the consent of the holders of the Series A Preferred Stock to the Company's engagement in the private offering of the Notes at a conversion price below the Conversion Price Floor, the stockholders of the Company, at the annual meeting on December 20, 2002, voted in favor of a proposal to remove the Conversion Price Floor and the designation of the Series A Preferred Stock was amended accordingly. Although the holders of the Series A Preferred Stock agreed to waive their rights to an immediate downward adjustment of the current $2.375 conversion price of the Series A Preferred Stock in connection with the issuance of the Notes, any subsequent conversion of the Notes will result in a downward adjustment of the conversion price of the Series A Preferred Stock to equal the conversion rate of the Notes. Consequently, upon conversion of the Exchange Notes at the $.79 per share conversion price the anti-dilution provisions of the Series A Preferred Stock will cause the conversion price of the Series A Preferred Stock to adjust downward to the $.79 per share. Assuming that the Series A Preferred Stock converts to common stock at a conversion price of $.79 per share and based upon 116,629 shares of Series A Preferred Stock issued as of December 31, 2002, the holders of the Series A Preferred Stock would receive 14,763,164 shares of common stock. Similarly, the conversion price of such Series A Preferred Stock may be subsequently adjusted to equal the consideration received by the Company in connection with any subsequent issuance of securities below $2.375.

The designation of the Series A Preferred Stock provided for a proxy granted by the holders of the Series A Preferred Stock in favor of certain of the Company's officers to vote all shares of Common Stock into which the Series A Preferred Stock converts (including any additional shares subsequently acquired by such holders) in excess of 29% of the votes entitled to be cast by the Series A Preferred Stock holders. As noted above, in consideration for consent of the holders of the Series A Preferred Stock to the Company's engagement in the private offering of Convertible Notes at a conversion rate below the Conversion Price Floor, the stockholders of the Company, at the annual meeting on December 20, 2002, voted in favor of a proposal to remove the proxy from the designation of the Series A Preferred Stock.

Item 14. Controls and Procedures

Within the 90-day period prior to the filing of this report, an evaluation was carried out under the supervision and with the participation of the Company's management, including the Chief Executive Officer ("CEO") and Chief Financial Officer ("CFO"), of the effectiveness of the Company's disclosure controls and procedures. Based on that evaluation, the CEO and CFO have concluded that the Company's disclosure controls and procedures are effective to ensure that information required to be disclosed by the Company in reports that it files or submits under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms. It should be noted that the design of any system of controls is based in part upon certain assumptions of the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under the potential future conditions, regardless of how remote such condition may be. Subsequent to the date of their evaluation, there were no significant changes in the Company's internal controls or in other factors that could significantly affect the internal controls, including any corrective actions with regard to significant deficiencies and material weaknesses.

Report of Independent Certified Accountants

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, 2002 and the related consolidated statements of operations, stockholders' equity and cash flows for each of the two years in the period ended December 31, 2002. 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 auditing standards generally accepted in the 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 examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Hudson Technologies, Inc. and subsidiaries as of December 31, 2002 and the results of their operations and their cash flows for each of the two years in the period ended December 31, 2002 in conformity with accounting principles generally accepted in the United States.

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 2 to the consolidated financial statements, the Company's credit facility expires in April 2003 and the Company has not renewed the agreement. This item has raised substantial doubt about its ability to continue as a going concern. Management's plans in regard to this matter is also described in Note 2. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

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(R) Services performed at a customer's site, consisting of system decontamination to remove moisture, oils and other contaminants and (iii) 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.

Fair value of financial instruments

The carrying values of financial instruments including trade accounts receivable, and accounts payable approximate fair value at December 31, 2002, 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, 2002.

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 that exceed FDIC insurance coverage. The Company's trade accounts receivables are due from companies throughout the U.S. 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 and the carrying value of its accounts receivable are reduced by the established allowance. The allowance for doubtful accounts includes any accounts receivable balances that are determined to be uncollectable, 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 collectibility of the accounts receivable balances.

During the year ended December 31, 2002, one customer accounted for 11% of the Company's revenues and as of December 31, 2002 there was $223,000 accounts receivable balance from this customer. During the year ended December 31, 2001, one customer accounted for 15% of the Company's revenues and as of December 31, 2001 there were no related accounts receivable balance from this customer. The loss of a principal customer or a decline in the economic prospects and purchases of the Company's products or services by any such customer could have an adverse effect on the Company's financial position and results of operations.

During the years ended December 31, 2002 and 2001, the Company had sales to E.I. DuPont de Nemours and Company ("DuPont"), an affiliate, in the amount of $974,000 and $1,124,000, respectively.

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 reclaimed 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 collectibility. In addition, each sale is based on an arrangement with the customer and the sales price to the buyer is fixed. 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 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(R) Services revenues. The revenues for each of these lines are as follows:

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 Company recognized a reserve allowance against the deferred tax benefit for the current and prior period losses. The tax benefit associated with the Company's net operating loss carry forwards would be recognized to the extent that the Company recognized net income in future periods.

Loss per common and equivalent shares

Loss per common share, Basic, is calculated based on the net loss for the period plus dividends on the outstanding Series A Preferred Stock, $796,000 and $723,000 for the years ended December 31, 2002 and 2001, respectively, divided by the weighted average number of shares outstanding. If dilutive, common equivalent shares (common shares assuming exercise of options and warrants or conversion of Preferred Stock) utilizing the treasury stock method are considered in the presentation of dilutive earnings per share. The effect of equivalent shares was not dilutive in either 2002 or 2001.

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 and reclaimable refrigerants from domestic suppliers and its customers. To the extent that the Company 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

41

estimates are not accurate, or circumstances change in the future, the Company could realize liabilities which would have a material adverse affect 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

The Company has historically 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.

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 earning per share using the fair value approach, are presented in the following table. These pro forma amounts may not be representative of future disclosures since the estimated fair value of stock options is amortized to expense over the vesting period, and additional options may be granted in future years.

Recent accounting pronouncements

In June 2001, the Financial Accounting Standards Board ("FASB") issued FASB statement No. 143, Accounting for Asset Retirement Obligations ("SFAS 143"). SFAS 143 addresses financial reporting for obligations associated with retirement of tangible long-lived assets and the associated retirement costs. SFAS 143 is effective for fiscal years beginning after June 15, 2002.

In April 2002, the FASB issued FASB statement No. 145 ("SFAS 145"), which rescinds FASB statements No. 4, 44 and 64 and amends FASB statement No. 13. SFAS 145 is effective for fiscal years beginning after May 15, 2002.

In June 2002, the FASB issued FASB statement No. 146, Accounting for Costs Associated with Exit or Disposal Activities ("SFAS 146"). SFAS 146 addresses financial accounting and reporting for costs associated with exit or disposal activities. SFAS 146 is effective for fiscal years beginning after December 31, 2002.

In December 2002, the FASB issued FASB statement No. 148, Accounting for Stock-Based Compensation - Transition and Disclosure ("SFAS 148"), an amendment of SFAS No. 123. SFAS 148 provides alternative methods of transition for a voluntary change to the fair value based method of accounting for stock-based employee compensation. The Company plans to continue to use the intrinsic value method for stock-based compensation. SFAS No. 148 is effective for fiscal years beginning after December 15, 2002.

The Company will adopt each of the above pronouncements effective January 1, 2003. Currently, the Company does not believe that these adoptions will have a material impact on its financial position and results of operations.

Note 2 - Liquidity and going concern

The Company has been substantially dependent on loans from CIT Group/Business Credit, Inc. ("CIT") and its principal stockholders, and proceeds from the sale of its securities. In addition, the agreement between CIT, the Company's primary lender, and the Company expires on April 29, 2003 and the Company has not obtained a renewal of this credit facility. Although the Company believes it can obtain replacement financing should CIT decide not to continue its lending relationship with the Company there can be no assurance that it can obtain such financing.

Even if the Company is able to replace its current credit facility with CIT the Company anticipates that it will need to raise additional capital in 2003. No assurances can be made that the Company will be successful in the sales of its securities or in obtaining an extension or renewal of its credit facility to meet the Company's working capital needs. The accompanying financial statements have been prepared on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business. As discussed above, the Company is dependent on outside sources of financing to fund its working capital needs. This condition gives rise to substantial doubt about the Company's ability to continue as a going concern. The financial statements do not include any adjustments that might result from this uncertainty.

Note 3 - Dispositions

Effective March 19, 1999, the Company sold 75% of its stock ownership in Environmental Support Solutions, Inc. ("ESS") to one of ESS's founders. The consideration for the Company's sale of its interest was $100,000 in cash and a six-year 6% interest bearing note in the amount of $380,000. The Company has recognized as income the portion of the proceeds associated with the note receivable upon the receipt of cash. The Company recognized a valuation allowance for 100% of the note receivable. Subsequent to March 19, 1999, in two separate transactions, ESS redeemed the balance of the Company's stock ownership in ESS and the proceeds from the redemption were included as other income. Pursuant to an agreement dated January 22, 2002, ESS and the Company agreed to a 16% discount of the outstanding balance on the note receivable. On January 25, 2002, as part of a capital financing completed by ESS, ESS paid the Company $231,951, representing the discounted balance as of that date, as full satisfaction of the note received and as of that date, the Company recognized the proceeds as other income.

Note 4 - Other income

For the year ended December 31, 2002, other income of $253,000 consisted primarily of the prepayment of the remaining balance of the note receivable from ESS and to a lesser extent, interest income. For the year ended December 31, 2001, other income of $230,000 consisted primarily of interest income, lease rental income from the Company's Ft. Lauderdale facility, which was sold on March 22, 2001, and payments received from the note receivable from ESS.

Note 5 - Income taxes

During the years ended December 31, 2002 and 2001, there was no income tax expense recognized due to the Company's net losses.

As of December 31, 2002, the Company has net operating loss carryforwards, ("NOL's") of approximately $27,900,000 expiring 2007 through 2022 for which a 100% valuation allowance has been recognized. Included in the NOL's are NOL's from Refrigerant Reclamation Corporation of America, acquired during 1995 as a subsidiary of the Company, in the amount of approximately $4,488,000, which are subject to annual limitations of approximately $367,000 and expire from 2007 through 2010.

Bank credit line and term loan

The Company has entered into a credit facility with CIT, which provides for borrowings to the Company of up to $6,500,000. The facility requires minimum borrowings of $1,250,000. The facility provides for a revolving line of credit and a term loan and expires in April 2003. Advances under the revolving line of credit are limited to (i) 80% of eligible trade accounts receivable and (ii) 50% of eligible inventory (which inventory amount shall not exceed 200% of eligible trade accounts receivable or $3,250,000). As of December 31, 2002, the Company had availability under its revolving line of credit of approximately $292,000. Advances available to the Company under the term loan are based on existing fixed asset valuations and future advances under the term loan of up to an additional $1,000,000 are based on future capital expenditures. As of December 31, 2002, the Company had approximately $303,000 outstanding under its term loans and $2,034,000 outstanding under its revolving line of credit and due to the expiration of the credit facility in April 2003, all such amounts are reflected on the Company's December 31, 2002 Balance Sheet as current liabilities. The facility bears interest at the prime rate plus 1.5%, 5.75% at December 31, 2002, and substantially all of the Company's assets are pledged as collateral for obligations to CIT. In addition, among other things, the agreements restrict the Company's ability to declare or pay any dividends on its capital stock. The Company has obtained a waiver from CIT to permit the payment of dividends on its Series A Preferred Stock.

The Company is currently in negotiations with CIT regarding a possible extension of the term of the credit facility or the entering into of a new credit facility and is also seeking alternate sources of financing. While the Company believes that it will be able to obtain replacement financing, there can be no assurance that CIT will continue to lend funds to the Company after the expiration of the current credit facility or that the Company will be able to obtain alternate financing from another source should CIT decide not to continue providing financing to the Company. However, even if the Company is able to obtain replacement financing it may be on terms that are less favorable to the Company than the current CIT credit facility. A failure of the Company to obtain financing from CIT or an alternate source after the expiration of the current CIT credit facility would have a material adverse affect on the Company's operations and financial condition.

Vehicle Loans

During 1999, the Company entered into various vehicle loans. The vehicles are primarily used in connection with the Company's on-site services. The loans are payable in 60 monthly payments through October 2004 and bear interest at 9.0% to 9.98%.

Scheduled maturities of the Company's long-term debts and capital lease obligations are as follows:

Loans from Related Parties

In November 2002, the Company consummated the private sale of unsecured 12% subordinated promissory notes ("Bridge Notes") to certain officers and certain members of their family and holders of the Series A Preferred Stock, for which it received gross proceeds of $655,000. The Bridge Notes were for a term of one year and were subordinate in payment to the Company's obligations under its credit facility with CIT. In accordance with the terms of the Bridge Notes, each of the purchasers, at their option, elected to defer quarterly interest payments which were to be added to the principal amount of the Bridge Notes as of each interest payment date and which accrued interest would, in turn, accrue interest at 12% per annum. The Bridge Notes automatically exchanged for unsecured convertible subordinated promissory notes, described in more detail immediately below, ("Exchange Notes") upon approval of such exchange by the Company's shareholders, which approval was obtained at the annual meeting on December 20, 2002.

Effective December 2002, the Company consummated the private sale of unsecured 10% convertible subordinated promissory notes ("Convertible Notes"), certain officers and certain members of their family and holders of the Series A Preferred Stock, for which it received gross proceeds of $495,000. At or about the same time, the Bridge Notes were cancelled and exchanged for the Exchange Notes in a principal amount equal to the outstanding principal amount of the Bridge Notes immediately prior to the exchange together with accrued and unpaid interest thereon. As of December 2002, the Exchange Notes and the Convertible Notes were identical in terms and together are referred to herein as the ("Notes"). The Notes have a term of two years and earn interest at an annual rate of 10% payable quarterly in arrears. Holders of the Notes had the one time option to elect to either receive payments of interest on a quarterly basis, subject to the limitations described below, or defer quarterly interest payments, in which case, interest would be added to the outstanding amount of the Notes on each quarterly payment date and accrue interest at the then effective Notes interest rate. The Notes are unsecured and subordinate in payment to the Company's obligations under its credit facility with CIT. The Notes may not be prepaid in cash by the Company without the prior consent of CIT and payment of interest, if any, in cash on any scheduled quarterly interest payment date is limited to an aggregate of $20,000 per calendar year. Holders of the Notes have the right to convert all or a portion of the outstanding principal balance, and any accrued interest thereon, to Common Stock of the Company, upon, but not prior to, the first anniversary of the issuance of the Notes at the conversion rate of $.79 per share (the average closing sale price of the Company's Common Stock as reported on the Nasdaq Small Cap Market for the five business days immediately preceding the issuance of the Notes), subject to certain anti-dilution adjustments (the "Conversion Rate").

In the event of a public offering of equity securities ("Equity Offering") by the Company at any time prior to the first anniversary of the issuance of the Notes, for gross proceeds of not less than $2 million (inclusive of the application of all outstanding principal and interest of the Notes), all outstanding principal and interest, if any, on the Notes shall be either (i) applied to the purchase of equity securities in the Equity Offering at the public offering purchase price, or (ii) converted into restricted shares of Common Stock at the then effective Conversion Rate. Holders of the Notes have the right to determine, to the extent that securities are legally available for purchase in the Equity Offering, whether to apply the Notes to acquire equity securities or convert the Notes into Common Stock; provided, however, that in the event that all or a portion of outstanding principal and interest, if any, of the Convertible Notes exceeds the number of equity securities available in the Equity Offering, the balance of the Notes not applied to the purchase of equity securities will be converted into restricted shares of Common Stock at the then-effective Conversion Rate.

The Conversion Rate of the Notes is subject to adjustment on a full ratchet basis (i.e., if the Company issues any stock at a price less than the Conversion Rate, the Conversion Rate for all shares issuable upon conversion of the Notes will be adjusted downward to such price) in certain events including the Company's issuance of Common Stock, warrants or rights to purchase Common Stock (except for shares subject to stock options under or reserved for option grants under any shareholder approved Stock Option Plan or upon exercise or conversion of options, warrants or other exercisable or exchangeable equity or debt securities outstanding immediately prior to the issuance of the Notes) or securities convertible into Common Stock in each case for a consideration per share which is less than the then-effective Conversion Rate. In addition, the Conversion Rate is subject to an appropriate adjustment in the event of: (i) any

46

subdivisions, combinations and reclassifications of the Company's Common Stock;
(ii) any payment, issuance or distribution by the Company to its stockholders of a stock dividend; (iii) the consolidation or merger of the Company with or into another corporation whereby the Company is not the surviving entity; or (iv) the sale by the Company of substantially all of its assets.

In April 2003, holders of the Convertible Notes holding an aggregate principal amount of $495,000 entered into agreements with the Company whereby the holders agreed to modify the Conversion Rate of their Convertible Notes to $1.13 (the average closing sale price of the Company's Common Stock as reported on the Nasdaq Small Cap Market for the five business days immediately preceding the execution of the modification agreements) (the "Modified Conversion Rate"); provided further, that, in the event of an Equity Offering by the Company prior to the first anniversary of the issuance of the Convertible Notes, at a public offering price (which includes the exercise price of stock purchase rights offered in the Equity Offering) below the Modified Conversion Rate but in excess of $.79, the Conversion Rate of the Convertible Notes will be adjusted to not less than the public offering price.

The Company is obligated to issue to the holders of the Notes, on the earlier of
(a) December 20, 2003, or (b) the consummation by the Company of an Equity Offering, Common Stock purchase warrants (the "Note Warrants") to purchase an aggregate number of shares of Common Stock equal to 10% of the number of shares of Common Stock into which the Notes were convertible at December 20, 2002. Each Note Warrant will be exercisable to purchase one share of Common Stock for a period of five years from issuance at an exercise price (the "Exercise Price") equal to 110% of the lesser of (i) the Conversion Price of the Notes as of December 20, 2002, or (ii) the Conversion Price of the Notes on the date of issuance of the Note Warrants. The Exercise Price of the Note Warrants will be subject to anti-dilution adjustment on terms substantially similar to the anti-dilution adjustment of the Conversion Rate of the Notes. As of December 20, 2002, the Company has recognized an original issue discount of $220,000, in connection with the issuance of the Note Warrants.

Average short-term debt for the year ended December 31, 2002 totaled $2,577,000 with a weighted average interest rate of approximately 6.15%.

Note 10 - Stockholders' equity

(i) On April 28, 1998, in connection with the loan agreements with CIT, the Company issued to CIT warrants to purchase 30,000 shares of the Company's common stock at an exercise price equal to 110% of the then fair market value of the stock, which on the date of issuance was $4.33 per share. The value of the warrants was not deemed to be material and the warrants expire on April 29, 2003. In addition, among other things, the agreements restrict the Company's ability to declare or pay any dividends on its capital stock. The Company has obtained a waiver from CIT to permit the payment of dividends on its Series A Preferred Stock.

(ii) On March 30, 1999, the Company completed the sale of 65,000 shares of its Series A Preferred Stock, with a liquidation value of $100 per share, to Fleming US Discovery Fund III, L.P. and Fleming US Discovery Offshore Fund III, L.P. The gross proceeds from the sale of the Series A Preferred Stock were $6,500,000. The Series A Preferred Stock currently converts to Common Stock at a price of $2.375 per share, which was 27% above the closing market price of Common Stock on March 29, 1999.

(iii) On February 16, 2001, the Company completed the sale of 30,000 shares of its Series A Preferred Stock, with a liquidation value of $100 per share, to Fleming US Discovery Fund III, L.P. and Fleming US Discovery Offshore Fund III, L.P. The gross proceeds from the sale of the Series A Preferred Stock were $3,000,000. The Series A Preferred Stock currently converts to Common Stock at a price of $2.375 per share, which was 23% above the closing market price of Common Stock on February 15, 2001.

The Series A Preferred Stock provides for anti-dilution adjustment of the conversion price in the event of the subsequent offering by the Company of securities for consideration per share less than the then effective conversion price of the Series A Preferred Stock. At the direction of the Nasdaq Stock Market, Inc., a minimum of $1.78 per share (the "Conversion Price Floor"), below which the conversion price of the Series A Preferred Stock could not be adjusted, had been instituted by the Company and the holders of the Series A Preferred Stock by amendment to the designation of the Series A Preferred Stock, and at the same time the Company agreed not to offer securities for consideration per share less than the Conversion Price Floor without the consent of the holders of the Series A Preferred Stock. Subsequently, in consideration for the consent of the holders of the Series A Preferred Stock to the Company's engagement in the private offering of the Notes at a conversion price below the Conversion Price Floor, the stockholders of the Company, at the annual meeting on December 20, 2002, voted in favor of a proposal to remove the Conversion Price Floor and the designation of the Series A Preferred Stock was amended accordingly. Although the holders of the Series A Preferred Stock agreed to waive their rights to an immediate downward adjustment of the current $2.375 conversion price of the Series A Preferred Stock in connection with the issuance of the Notes, any subsequent conversion of the Notes will result in an immediate downward adjustment of the conversion price of the Series A Preferred Stock to equal the conversion rate of the Notes. Consequently, upon conversion of the Exchange Notes at the $.79 per share conversion price the anti-dilution provisions of the Series A Preferred Stock will cause the conversion price of the Series A Preferred Stock to adjust downward to the $.79 per share. Assuming that the Series A Preferred Stock converts to common stock at a conversion price of $.79 per share and based upon 116,629 shares of Series A Preferred Stock issued as of December 31, 2002, the holders of the Series A Preferred Stock would receive 14,763,164 shares of common stock. Similarly, the

47

conversion price of such Series A Preferred Stock may be subsequently adjusted to equal the consideration received by the Company in connection with any subsequent issuance of securities below $2.375.

The Series A Preferred Stock has voting rights on an as-if converted basis. The number of votes applicable to the Series A Preferred Stock is equal to the number of shares of Common Stock into which the Series A Preferred Stock is then convertible. The designation of the Series A Preferred Stock provided for a proxy granted by the holders of the Series A Preferred Stock in favor of certain of the Company's officers to vote all shares of Common Stock into which the Series A Preferred Stock converts (including any additional shares subsequently acquired by such holders) in excess of 29% of the votes entitled to be cast by the Series A Preferred Stock holders. As noted above, in consideration for consent of the holders of the Series A Preferred Stock to the Company's engagement in the private offering of the Notes at a conversion rate below the Conversion Price Floor, the stockholders of the Company, at the annual meeting on December 20, 2002, voted in favor of a proposal to remove the proxy from the designation of the Series A Preferred Stock and the designation of the Series A Preferred Stock was amended accordingly. The Series A Preferred Stock carries a dividend rate of 7%, which will increase to 16%, if the stock remains outstanding on or after March 31, 2004. The Company used the net proceeds from the issuance of the Series A Preferred Stock to expand its RefrigerantSide(R) Services business and for working capital purposes.

The Company pays dividends, in arrears, on the Series A Preferred Stock, semi annually, either in cash or additional shares, at the Company's option. On March 30 and September 30, 2002, the Company declared and paid, in-kind, the dividends outstanding on the Series A Preferred Stock and issued 3,873 and 4,011, respectively, additional shares of its Series A Preferred Stock in satisfaction of the dividends due. The Company may redeem the Series A Preferred Stock on March 31, 2004 either in cash or shares of Common Stock valued at 90% of the average trading price of the Common Stock for the 30 days preceding March 31, 2004. In addition, after March 30, 2001, the Company may call the Series A Preferred Stock if the market price of its Common Stock is equal to or greater than 250% of the conversion price and the Common Stock has traded with an average daily volume in excess of 20,000 shares for a period of thirty consecutive days.

The Company has provided certain registration, preemptive and tag along rights to the holders of the Series A Preferred Stock. The holders of the Series A Preferred Stock, voting as a separate class, have the right to elect up to two members to 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 have the right to attend and observe meetings of the Board of Directors. Currently, the holders have elected one member to the Board of Directors.

(iv) The Company engaged an advisor to facilitate the Company's efforts in connection with the March 30, 1999 sale of the Series A Preferred Stock. In addition to the advisor fees, the Company issued to the advisor, warrants, which expire on March 30, 2004, to purchase 136,482 shares of the Company's Common Stock at an exercise price per share of $2.73. The value of the warrants was not deemed to be material.

Legal Proceedings

In June 1998, United Water of New York Inc. ("United") commenced an action against the Company in the Supreme Court of the State of New York, Rockland County, seeking damages in the amount of $1.2 million allegedly sustained as a result of alleged contamination of certain of United's wells which are in close proximity to the Company's Hillburn, New York facility.

On April 1, 1999, the Company reported a release at the Company's Hillburn, New York facility of approximately 7,800 lbs. of R-11, as a result of a failed hose connection to one of the Company's outdoor storage tanks allowing 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 at the Company's Hillburn facility to remove R-11 levels in the groundwater under and around the Company's facility. The cost of this remediation system was $100,000.

In July 1999, United amended its complaint in the Rockland County action to allege facts relating to, and to seek damages allegedly resulting from the April 1, 1999 R-11 release.

In June 2000, the Rockland County Supreme Court approved a settlement of the Rockland County action commenced by United. Under the settlement, the Company paid to United the sum of $1,000,000 and has been making additional monthly payments in the amount of $5,000, which payments will continue through December 2003. The proceeds of the settlement were required to be used to fund the construction and operation by United of a new remediation tower, as well as for the continuation of temporary remedial measures implemented by United that have successfully contained the spread of R-11. The remediation tower was completed in March 2001, and is designed to treat all of United's impacted wells and restore the water to New York State drinking water standards for supply to the public. The Company carries $1,000,000 of pollution liability insurance per occurrence and in connection with the settlement, exhausted all insurance proceeds available for that occurrence under all applicable policies.

In June 2000, the Company signed an Order on Consent with the DEC regarding all past contamination of the United well field, whereby, the Company agreed to continue operating the remediation system it installed at its Hillburn facility in May 1999, until remaining groundwater contamination has been effectively abated. In May 2001, the Company signed an amendment to the Order on Consent with the DEC, pursuant to which the Company installed one additional monitoring well and modified the Company's existing remediation system to incorporate a second recovery well. The Company is continuing to operate the remediation system.

In May 2000, the Company's Hillburn facility was nominated by the United States Environmental Protection Agency ("EPA") for listing on the National Priorities List ("NPL"), pursuant to the Comprehensive Environmental Response, Compensation and Liability Act of 1980. The Company believes that the agreements reached with the DEC and United Water, together with the reduced levels of contamination present in the United Water wells, make such listing unnecessary and counterproductive. Hudson submitted opposition to the listing within the sixty-day comment period. To date, no final decision has been made by the EPA regarding the proposed listing.

In October 2001, the Company learned that trace levels of R-11 were detected in one of United's wells that is closest to the Village of Suffern's ("Village") well system. During February 2002, the Village expressed concern over the possibility of R-11 reaching its well system and has advised the Company that it was investigating available options to protect its well system. No contamination of R-11 has ever been detected in any of the Village's wells and, as of October 2002, the level of R-11 in the United well closest to the Village was below 1 ppb. In October, 2002 the Village advised the Company it intends to proceed with plans to protect its wells and could

49

look to the Company to reimburse the Village for any costs it may incur. To date, no detailed cost estimate, formal demand or claim has been presented by the Village, however, to the extent the Village proceeds with its plans, the Company may incur additional costs. The Company has agreed to reimburse the Village for approximately $10,000 of costs incurred to date for additional sampling by the Village of its wells and for minor preparatory work in connection with the Village's plan for protecting its wells. The Company continues to work with the Village, and all applicable governmental agencies, to prevent contamination of Village's wells and its water supply.

In February 2003, the Company agreed to extend the statute of limitations applicable to any claims that may be available to Ramapo Land Company, the lessor of the Hillburn facility, arising out of the April 1, 1999 incident for an additional two years. To date, no claims against the Company have been asserted or threatened by Ramapo Land Company.

During the year ended December 31, 2002, the Company charged to operating expense $115,000 in additional remediation costs in connection with these matters. There can be no assurance that the R-11 will not spread beyond the United Water well system and impact the Village of Suffern's wells, or that the ultimate outcome of such a spread of contamination will not have a material adverse effect of the Company's financial condition and results of operations. There can be no assurance that the Company's opposition to the EPA's listing of the Company's Hillburn facility on the NPL will be successful, 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. Furthermore, there can be no assurance that Ramapo Land Company will not assert any claim against the Company, or that any such claim will not have a material adverse effect on the Company's financial condition and results of operations.

Note 12 - Stock Option Plans

Effective October 31, 1994, the Company adopted an Employee Stock Option Plan ("1994 Plan") pursuant to which 725,000 shares of common stock are 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, or (ii) nonqualified options. ISOs may be granted under the 1994 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 sooner terminated, the 1994 Plan will expire on December 31, 2004.

ISOs granted under the 1994 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 1994 Plan may not be granted at a price less than 85% of the market value of the common stock on the date of grant. Options granted under the 1994 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 July 25, 1997, and as amended on August 19, 1999, the Company adopted its 1997 Employee Stock Option Plan ("1997 Plan") pursuant to which 2,000,000 shares of common stock are 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, 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 sooner terminated, 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 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 on the date of grant. 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).

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.

SFAS No. 123 requires the Company to provide pro forma information regarding net loss and net loss per share as if compensation cost for the Company's stock option plan had been determined in accordance with the fair value based method prescribed in SFAS No. 123. The Company estimates the fair value of each stock option at the grant date by using the Black-Scholes option-pricing model with the following weighted-average assumptions used for grants since 1995.

10% SUBORDINATED CONVERTIBLE NOTE

$_________________ December 20, 2002

Pearl River, New York

MAKER'S PROMISE TO PAY

FOR VALUE RECEIVED, Hudson Technologies, Inc., a New York Corporation having its principal offices located at 275 North Middletown Road, Pearl River, New York (the "Maker") promises to pay, subject to the Conditions to Repayment as set forth below, to the order of __________________________________ (the "Payee") having an address at ________________, at Payee's address set forth above (or at such other place as the holder of this Note may from time to time direct by notice in writing to Maker), the principal sum of ______________________________($00.00) Dollars in such coin or currency of the United States as shall at the time be legal tender for the payment of public and private debts, on December , 2004 (the "Maturity Date") as evidenced by this instrument (the "Note"). The Payee, assignee or anyone entitled to receive payments under this Note shall be hereinafter referred to as the "Note Holder".

INTEREST

Interest will be charged on the outstanding principal of this Note from time to time until the full amount of principal has been paid, at an annual rate of ten (10.00%) percent (the "Note Rate").

PAYMENTS

Subject to the Conditions to Repayment set forth below, interest accrued on the outstanding principal amount of this Note shall be payable quarterly, in arrears, on each of April 1, July 1, October 1, and January 1, (each an "Interest Payment Date"), commencing on April 1, 2003. Payments shall be deemed timely if made within fifteen (15) days of the Interest Payment Date. The remainder accrued interest shall be payable in full on the earlier to occur of
(i) the Maturity Date and (ii) the date of the occurrence of an Event of Default hereunder.

[Interest accrued on the outstanding principal amount of this Note shall otherwise be payable quarterly in arrears on each of April 1, July 1, October 1, 2003 and January 1, (each an "Interest Payment Date"). Payee however has elected to defer the payments of interest accruing on the outstanding principal of this Note until the Maturity Date of the Note and all such deferred interest will be added to the unpaid principal amount of the Note on each Interest Payment Date and will accrue interest at the Note Rate.]

Interest shall accrue on past due principal and accrued and unpaid interest (other than with respect to interest payments made within the grace period after an Interest Payment Date as noted above in paragraph a) at the annual rate of fifteen (15%) percent (the "Default Rate"). Notwithstanding anything to the contrary contained in this Note, Maker shall not be obligated to pay, and the Payee shall not be entitled to charge, collect or receive, interest in excess of the maximum rate allowed by applicable law. During any period of time in which the interest rate specified herein exceeds such maximum rate, interest shall accrue and be payable at such maximum rate. Any amounts of interest collected by Payee in excess of such maximum rate shall be deemed to apply to principal and all payments of interest and principal shall be recalculated to allow for such characterization.

All payments received on account of this Note shall be applied first to the payment of accrued interest on this Note and then to the reduction of the unpaid principal balance of this Note. Interest, whether at the Note Rate or the Default Rate, shall be computed on the basis of a year of 360 days, for the actual number of days elapsed.

[Other than with respect to the deferred quarterly interest payments], In the event that the date for payment of any amount payable under this Note falls due on a Saturday, Sunday or public holiday under the laws of the State of New York, then such payment shall be made on the first business day following the date on which such payment shall have so fallen due, without any interest or other payment in respect of such delay, with the same force and effect as if made on the date payment had originally fallen due.

MAKER'S RIGHT TO PREPAY

Subject to the Conditions to Repayment set forth below, upon twenty (20) days prior written notice, Maker has the right to prepay, only in shares of common stock, par value $.01 per share ("Common Stock") of the Maker based upon the Conversion Rate (as defined below) of the Notes then in effect, all or any portion of this Note without the consent of the holder and without a prepayment penalty.


Any partial prepayment shall be first applied to all accrued and unpaid interest outstanding as of the date of the prepayment before applying any prepayment to reduce the outstanding principal amount of the Note.

CONDITIONS TO REPAYMENT

Until all Obligations under the Loan Agreement dated as of April 29, 1998 (the Loan Agreement), between The CIT Group/Business Credit, Inc. ("CIT Group") and Hudson Technologies Company ("Hudson"), a wholly-owned subsidiary of the Maker, are fully and finally paid and satisfied, the Maker shall not pay in cash any principal or interest outstanding under this Note, including any cash prepayment of principal or interest. For purposes of this Section 5, the term "Obligations" means all revolving credit facilities, term loans, loans made for the purpose of financing capital expenditures and accommodations including, without limitation, letters of credit, bankers' acceptances, merchandise purchase guarantees or other guarantees or indemnities for Hudson's account, currently outstanding or hereinafter incurred and made or extended to Hudson by CIT Group and evidenced by the Loan Agreement.

Notwithstanding anything to the contrary set forth in paragraph 5.1 above, the Maker may make:

cash payments of interest on each Interest Payment Date provided that: (i) no event of default under the Loan Agreement shall then exist or have occurred and be continuing which event of default shall not have been cured by Hudson or Maker or waived by CIT Group, and (ii) the aggregate amount of such payments of interest by the Maker to the holders of notes of the series of which this Note forms a part (the "Convertible Notes" which includes the convertible promissory notes ("Exchange Notes") issued in exchange ("Note Exchange") for the Maker's bridge notes and which Exchange Notes are identical in terms to the Convertible Notes), shall not exceed $20,000 in any calendar year; and

cash payments of principal on the Maturity Date provided that: (i) no event of default under the Loan Agreement shall then exist or have occurred and be continuing, which event of default shall not have been cured by Hudson or Maker or waived by CIT Group, and (ii) immediately after giving effect to any such payment of principal and to any related payment or funding by Hudson to Maker, Hudson having net availability (as such term is defined in the Loan Agreement) of not less than $200,000 and combined net availability and cash balances of not less then $850,000.

In the event that the cash payment of interest to Note Holders on any Interest Payment Date shall exceed the maximum allowable pursuant to Section 5.2(a) above, such cash payment of interest shall be made on a pro rata basis among the Note Holders entitled to such interest payment based upon the percentage of each such Note Holder's aggregate principal and accrued interest as of such Interest Payment Date, against the aggregate principal amount and accrued interest under the Notes held by the Note Holders entitled to such interest payment as of the Interest Payment Date; and the balance of any such interest payment to each Note Holder entitled thereto shall be added to principal amount of such Note Holder's Note on the Interest Payment Date and shall accrue interest at the Note Rate.

This note is subject to the terms of a separate written consent by and between, among others, maker, Hudson Technologies Company, CIT Group and Payee.

MAKER'S FAILURE TO PAY AS REQUIRED

Not in limitation of any other right at law or in equity, upon the occurrence of any of the following events of default (each, an "Event of Default"), the unpaid principal amount of this Note shall become immediately due and payable by the Maker, together with the interest accrued thereon, without presentment, demand, protest or further notice of any kind, all of which are hereby expressly waived by the Maker:

Other than as a result of the restrictions set forth in Section 5 above, the Maker's failure to make any payment of principal and/or interest due under this Note on the date the same is due;

Other than as a result of the restrictions set forth in Section 5 above, the Maker's failure to keep and perform all promises, agreements, conditions and provisions of this Note, which, if such default does not involve the payment of money, is not cured within ten days;

The Maker makes a general assignment for the benefit of creditors; or files a voluntary petition in bankruptcy, or a petition for reorganization, arrangement, composition, readjustment or similar relief under any present or future statute, law or regulation, or shall file an answer admitting or not contesting the material allegations of a petition against it in any such proceeding; or admits in writing its inability to pay its debts as they become due; or permits an attachment to be made on any substantial part of Maker's property or assets; or if an involuntary petition in bankruptcy is filed against any obligor and not dismissed within sixty (60) days; or if a receiver or trustee is appointed for all or any part of the property and assets of any obligor.

Upon any such Event of Default, Maker will be liable to the Note Holder for interest at the Default Rate from the date of such Event of Default, together with all reasonable expenses incurred by the Note Holder in the collection of this indebtedness resulting from such Event of Default, including, without limitation, the Note Holder's reasonable fees for one attorney of its choice for representation of the Note Holder in connection with the collection of such indebtedness.

REQUIRED NOTICES

Unless applicable law requires a different method, any notice required to be given to any of the parties hereto shall be in writing and shall be deemed to have been sufficiently given by delivering it or by mailing it by first class mail to such party at the address set forth above or any alternate address as provided by such party in writing.

CONVERSION

The Note Holder, at his or its option, is entitled, upon but not prior to the first anniversary of the date of this Note and at any time prior to the payment in full of the principal amount of this Note by the Maker, to convert all of the principal amount of this Note at the time outstanding or any portion thereof, together with accrued but unpaid interest thereon, into shares ("Conversion Shares") of Common Stock at an initial conversion price equal to the average closing price of the Maker's Common Stock as reported on the Nasdaq Small


Cap Market for the five business days preceding the date of this Note, which shall be subject to adjustment from time to time pursuant to this Section 8 ("Conversion Rate").

Conversion of this Note, and accrued and unpaid interest thereon, may be effected by the Note Holder transmitting to the Maker, at its principal office by facsimile transmission, a written notice (a "Conversion Notice") stating the principal amount of the Note the Note Holder elects to convert in accordance with the provisions of this Section 8.2 and specifying the name or names in which such Note Holder wishes the certificate or certificates for Conversion Shares to be issued and by delivering to the Maker, at such principal office within ten (10) business days thereafter, the original Conversion Notice and this Note by express courier. In case the Conversion Notice specifies a name or names other than that of the Note Holder, such notice shall be accompanied by payment of all transfer taxes payable upon the issuance of Conversion Shares in such other name or names. Other than such taxes, the Maker will pay any and all issue and other taxes (other than taxes based on income) that may be payable in respect of any issue or delivery of Conversion Shares pursuant hereto. As promptly as practicable, and in any event within five (5) business days after the date of the receipt by the Maker of this Note or Notes and the receipt of the original Conversion Notice relating thereto (the "Delivery Date") and, if applicable, payment of all transfer taxes (or the demonstration to the satisfaction of the Maker that such taxes have been paid), the Maker shall deliver or cause to be delivered to Note Holder, by express courier, certificates representing the number of validly issued, fully paid and nonassessable full Conversion Shares to which the Note Holder shall be entitled. Such conversion shall be deemed to have been made at the close of business on the date of receipt by the Maker of a Conversion Notice by facsimile transmission as permitted by this provisions of this Section 8.2, so that the rights of the Note Holder under this Note shall cease, except for the right to receive Conversion Shares with respect to the principal amount and accrued unpaid interest thereon so converted and a new Note for any principal amount remaining unpaid, and the person entitled to receive such Conversion Shares shall be treated for all purposes as having become the record holder of such Conversion Shares at such time, provided that if this Note and the original Conversion Notice are not received by the Maker within ten (10) business days after the Maker's receipt of a Conversion Notice by facsimile transmission, the rights of the Note Holder under this Note (to the extent converted) will cease at the close of business on the day the Maker actually receives the original Note and the original Conversion Notice pertaining thereto.

Notwithstanding any contrary provision contained herein, at any time prior to the first anniversary of this Note, all of the outstanding principal and accrued interest of the Note shall either (i) be applied to the purchase of securities to be offered by the Maker at the public offering purchase price, in any public offering by the Maker of equity securities which, when aggregating the outstanding principal and accrued interest of the Convertible Notes and all additional proceeds from new investors, equals not less than $2,000,000 (the "Equity Offering"), or (ii) in the event of such Equity Offering, be converted into Conversion Shares at the then-effective Conversion Rate. The Note Holder will have the right to determine, to the extent that securities are available for purchase in the Equity Offering, whether to apply the outstanding principal and interest, if any, of this Note to the purchase of the securities in the Equity Offering or to convert the same into Conversion Shares at the then-effective Conversion Rate; provided, however, that in the event that all or a portion of outstanding principal and interest, if any, of this Note exceeds the number of equity securities available in the Equity Offering, the balance of this Note not applied to the purchase of equity securities will be converted into Conversion Shares at the then-effective Conversion Rate.

Upon conversion, the Note Holder shall be entitled at the Note Holder's option, to receive any accrued and unpaid interest on the principal amount of this Note converted, to the date of such conversion, in the form of Conversion Shares.

In connection with the conversion of this Note, no fractional amount of Conversion Shares shall be issued, but, in lieu thereof, the Maker shall round such fractional amount to the nearest whole Conversion Share.

The Maker shall at all times reserve and keep available for issuance upon the conversion of this Note, such number of its authorized but unissued shares of Common Stock as will from time to time be sufficient to permit the conversion of this Note in full, and shall take all action required to increase the authorized number of shares of Common Stock if necessary to permit the conversion of this Note in full.

o Except with respect to the securities set forth in paragraph (b) below, in case the Maker shall at any time after the date hereof issue or sell any shares of Common Stock, including shares held in the Maker's treasury, or shall issue any options, rights or warrants to subscribe for shares of Common Stock or other equity or debt securities exercisable into or exchangeable for shares of Common Stock (each, an "Additional Issuance"), for a consideration per share less than the Conversion Rate then in effect, the Conversion Rate shall be adjusted immediately thereafter such that it shall equal the consideration per share received by the Maker for the securities issued in such Additional Issuance. Such adjustment shall be made successively whenever such an Additional Issuance is made for consideration per share below the Conversion Rate then in effect.

The adjustment of the Conversion Rate set forth in paragraph (a) above shall not apply to options granted by the Maker pursuant to stockholder-approved option plans of the Maker nor to the issuance of Common Stock upon exercise of such options or upon the exercise of options, warrants or other securities exercisable for or exchangeable into Common Stock outstanding immediately prior to the date of this Note or the conversion of convertible debt of the Maker outstanding immediately prior to the date of this Note.

o In the event that, at any time and from time to time, the Maker shall issue additional shares of Common Stock (or securities convertible into or exchangeable for Common Stock) in a stock dividend, stock distribution, or subdivision paid with respect to Common Stock, or declare any dividend or other distribution payable with additional shares of Common Stock (or securities convertible into or exchangeable for Common Stock) with respect to Common Stock, or effect a split or subdivision of the outstanding shares of Common Stock, the Conversion Rate shall, concurrently with the effectiveness of such stock dividend, stock distribution, or subdivision, or the earlier declaration thereof, be proportionately decreased, and the number of shares of Common Stock issuable upon conversion of this Note shall be proportionately adjusted such that, to avoid dilution of the Note Holder's position, the Note Holder


shall thereafter be entitled to receive on conversion of this Note an additional number of shares of Common Stock which such Note Holder would received upon or by reason of any of the events described above, had this Note been converted immediately prior to the occurrence of such event.

In the event the outstanding shares of Common Stock shall be combined or consolidated, by reclassification or otherwise, into a lesser number of shares of Common Stock, the Conversion Rate shall, concurrently with the effectiveness of such combination or consolidation, be proportionately increased and the number of shares of Common Stock issuable upon conversion of this Note shall be proportionately adjusted so that the Note Holder shall be entitled to receive upon conversion of this Note, the aggregate number of shares of Common Stock which such Note Holder would have been entitled to receive if this Note had been converted immediately prior to the occurrence of such combination or consolidation.

In case of any consolidation or merger of the Maker with or into another corporation or entity in which the Maker is not the surviving or resulting company, or in case of any sale or conveyance to another company or entity of all or substantially all of the assets of the Maker (each of the foregoing being referred to as a "Transaction"), this Note shall thereafter be convertible into, in lieu of Common Stock issuable upon such conversion prior to consummation of such Transaction, the kind and amount of shares of stock and other securities and/or property receivable (including cash) upon the consummation of such Transaction by a holder of that number of shares of Common Stock into which this Note was convertible immediately prior to such Transaction (including, on a pro rata basis, the cash, securities or property received by holders of Common Stock in any tender or exchange offer that is a step in such Transaction). In case securities or property other than Common Stock shall be issuable or deliverable upon conversion as aforesaid, then all references in this Section 8 shall be deemed to apply, so far as appropriate and nearly as may be, to such other securities or property.

For the purposes of any computation to be made in accordance with this Section, the following provisions shall be applicable: (a) in case of the issuance or sale of shares of Common Stock for a consideration part or all of which shall be cash, the amount of the cash consideration therefor shall be deemed to be the amount of cash received by the Maker for such shares (or, if shares of Common Stock are offered by the Maker for subscription, the subscription price); (b) in case of the issuance or sale (otherwise than as a dividend or other distribution on any stock of the Maker) of shares of Common Stock for a consideration part or all of which shall be other than cash, the amount of the consideration therefor other than cash shall be deemed to be the value of such consideration as determined in good faith by the Board of Directors of the Maker; (c) shares of Common Stock issuable by way of dividend or other distribution on any stock of the Maker shall be deemed to have been issued immediately after the opening of business on the day following the record date for the determination of shareholders entitled to receive such dividend or other distribution and shall be deemed to have been issued without consideration; (d) the reclassification of securities of the Maker other than shares of Common Stock into securities including shares of Common Stock shall be deemed to involve the issuance of such shares of Common Stock for a consideration other than cash immediately prior to the close of business on the date fixed for the determination of security holders entitled to receive such shares, and the value of the consideration allocable to such shares of Common Stock shall be determined as provided above; and (e) the number of shares of Common Stock at any one time outstanding shall include the aggregate number of shares issued or issuable upon the exercise of options, rights, warrants and upon the conversion or exchange of convertible or exchangeable securities.

The Maker shall not, by amendment of its Articles of Incorporation or through any reorganization, transfer of assets, consolidation, merger, dissolution, issue or sale of securities or any other voluntary action, avoid or seek to avoid the observance or performance of any of the terms to be observed or performed hereunder by the Maker but will at all times in good faith assist in the carrying out of all the provisions of this Section 8 and in the taking of all such action as may be necessary or appropriate in order to protect the conversion rights of the holders of the Convertible Notes against impairment.

Upon the occurrence of each adjustment to the Conversion Rate pursuant to this
Section 8, the Maker, at its expense, shall cause its independent auditors to promptly compute such adjustment in accordance with the terms hereof and furnish to each holder of Convertible Notes a certificate of such auditors setting forth such adjustment and showing in detail the facts upon which such adjustment is based.

The Maker shall mail to each holder of Convertible Notes at their addresses as shown on the records of the Maker, as promptly as possible, but in any event not fewer than 15 days prior to the applicable record date, a notice stating (i) the date on which any merger, consolidation, recapitalization, or reorganization of the Maker, or sale of all or substantially all of the Maker's assets, or any other similar transaction or any corporate transaction requiring the vote of the stockholders of the Maker, (ii) the record date therefor, and (iii) the consideration (by class and series) to be paid to holders of capital stock of the Maker upon consummation thereof.

ISSUANCE OF WARRANTS

On the earlier of (a) December 20, 2003, or (b) the consummation by the Maker of an Equity Offering described in Section 8.3 above, the Maker will issue to the Note Holder Common Stock purchase warrants (the "Convertible Note Warrants") to purchase an aggregate number of shares of Common Stock equal to 10% of the number of shares of Common Stock into which this Note is convertible at December 20, 2002. Each Convertible Note Warrant will be exercisable to purchase one share of Common Stock for a period of five years from issuance at an exercise price (the "Exercise Price") equal to 110% of the lesser of (i) the Conversion Rate of this Note as of December 20, 2002, or (ii) the Conversion Rate of this Note on the date of issuance of the Convertible Note Warrants. The Exercise Price of the Convertible Note Warrants will be subject to anti-dilution adjustment on terms substantially similar to the anti-dilution adjustment of the Conversion Rate of this Note set forth in Section 8 above.


MISCELLANEOUS

No delay or omission by the Note Holder in exercising any right or power hereunder shall operate as a waiver of such right or power, and a waiver on one occasion shall not be construed as a waiver or a bar to the exercise of any right on any other occasion.

The rights and remedies of the Note Holder as provided in this Note shall be cumulative and concurrent, and may be pursued singly, successively, or together at the sole discretion of the Note Holder. The failure to exercise any such right or remedy shall in no event be construed as a waiver or release of said rights or remedies or of the right to exercise them at any time later.

None of the terms and conditions of this Note may be amended, modified or waived orally, but only in a writing signed by the Maker and the Note Holder.

This Note shall be governed by, and construed in accordance with, the domestic laws of the State of New York, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of New York or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of New York.

If any term or provision of this Note shall be held invalid, illegal or unenforceable, the validity of all other terms and provisions hereof shall in no way be affected hereby.

This Note shall be binding upon the Maker and the Maker's successors and assigns; provided that the Maker may not assign this Note without the Note Holder's consent.

Warrant for the Purchase of Shares of
Common Stock

_______ Shares

FOR VALUE RECEIVED, HUDSON TECHNOLOGIES, INC., a New York corporation (the "Company"), hereby certifies that [___________] or registered assigns (the "Holder") is entitled to purchase from the Company, subject to the provisions of this Warrant (the "Warrant"), at any time on or after ___________, 200_ (the "Initial Exercise Date") [insert the date which is the earlier of (i) the first anniversary of the date of issuance of Holder's 10% Subordinated Convertible Promissory Note ("Convertible Note") and (ii) the consummation of an Equity Offering (as defined in the Company's proxy statement dated November 20, 2002) by the Company], and prior to 5:00 P.M., New York City time, on or prior to _________, 200_ (the "Termination Date") [the date which is the fifth anniversary of the Initial Exercise Date], ____________________ (________) fully paid and non-assessable shares of the Common Stock, $.01 par value, of the Company ("Common Stock") [equal to 10% of the number of shares of Common Stock into which the Holder's Convertible Note was convertible on its issue date], at an initial exercise price of $[____] [equal to 110% of the lesser of the conversion rate of the Holder's Convertible Note (i) as of its issue date, or
(ii) as of the date this Warrant is issued] per share of Common Stock (the "Initial Per Share Exercise Price"). The number of shares of Common Stock to be received upon exercise of this Warrant and the price to be paid for each share of Common Stock are subject to possible adjustment from time to time as hereinafter set forth. The shares of Common Stock or other securities or property deliverable upon such exercise as adjusted from time to time is hereinafter sometimes referred to as the "Warrant Shares." The exercise price of a share of Common Stock in effect at any time and as adjusted from time to time is hereinafter sometimes referred to as the "Per Share Exercise Price." The Per Share Exercise Price is subject to adjustment as hereinafter provided.

Exercise of Warrant.


This Warrant may be exercised in whole or in part, at any time by its holder commencing on the Initial Exercise Date and prior to the Termination Date by presentation and surrender of this Warrant, together with the duly executed subscription form and representations and warranties attached at the end hereof, at the address set forth in Subsection 7(a) hereof, together with payment, by certified or official bank check or wire transfer payable to the order of the Company, of the product of (x) the Per Share Exercise Price multiplied by (y) the number of shares of Common Stock subject to (1) this Warrant or (2) the proportionate part thereof if exercised in part.

If this Warrant is exercised in part only, the Company shall, upon presentation of this Warrant upon such exercise, execute and deliver (along with the certificate for the Warrant Shares purchased) a new Warrant evidencing the rights of the Holder hereof to purchase the balance of the Warrant Shares purchasable hereunder upon the same terms and conditions as herein set forth. Upon proper exercise of this Warrant, the Company promptly shall deliver certificates for the Warrant Shares to the Holder duly legended as authorized by the subscription form. No fractional shares or scrip representing fractional shares shall be issued upon exercise of this Warrant; provided that the Company shall pay to the holder of the Warrant cash in lieu of such fractional shares.

Reservation of Warrant Shares; Fully Paid Shares; Taxes.

The Company hereby represents that it has, and until expiration of this Warrant agrees that it shall, reserve for issuance or delivery upon exercise of this Warrant, such number of shares of Common Stock as shall be required for issuance and/or delivery upon exercise of this Warrant in full, and agrees that all Warrant Shares so issued and/or delivered will be validly issued, fully paid and non-assessable, and further agrees to pay all taxes and charges (other than income taxes) that may be imposed upon such issuance and/or delivery. The Company shall not, however, be required to pay any tax which may be payable in respect of any transfer involved in the issue or delivery of Common Stock (or other securities or assets) in a name other than that in which this Warrant is registered, and no such issue or delivery shall be made unless and until the person requesting such issue has paid to the Company the amount of such tax or has established, to the satisfaction of the Company, that such tax has been paid or need not be paid.

Protection Against Dilution.

Except with respect to the securities set forth in paragraph (b) below, in case the Company shall at any time after the date hereof issue or sell any shares of Common Stock, including shares held in the Company's treasury, or shall issue any options, rights or warrants to subscribe for shares of Common Stock or other equity or debt securities exercisable into or exchangeable for shares of Common Stock (each, an "Additional Issuance"), for a consideration per share less than the Per Share Exercise Price then in effect, the Per Share Exercise Price shall be adjusted immediately thereafter such that it shall equal the consideration per share received by the Company for the securities issued in such Additional Issuance. Such adjustment shall be made successively whenever such an Additional Issuance is made for consideration per share below the Per Share Exercise Price then in effect.

The adjustment of the Per Share Exercise Price set forth in paragraph (a) above shall not apply to options granted by the Company pursuant to stockholder-approved option plans of the Company nor to the issuance of Common Stock upon exercise of such options or upon the exercise of options, warrants or other securities exercisable for or exchangeable into Common Stock outstanding immediately prior to the date of this Warrant or the conversion of convertible debt of the Company outstanding immediately prior to the date of this Warrant.

In case the Company shall hereafter (i) pay a dividend or make a distribution on its Common Stock in shares of Common Stock, (ii) subdivide its outstanding shares of Common Stock into a greater number of shares or (iii) combine its outstanding shares of Common Stock into a smaller number of shares (each of (i) through (iii) an "Action"), then the Per Share Exercise Price shall be adjusted to be equal to the product of (i) a fraction, the numerator of which is the number of shares of Common Stock outstanding immediately prior to such Action and the denominator of which is the number of shares of Common Stock outstanding immediately following such Action, multiplied by (ii) the Per Share Exercise Price immediately prior to such Action. An adjustment made pursuant to this Subsection 3(a) shall become effective immediately after the record date in the case of a dividend or distribution and shall become effective immediately after the effective date in the case of a subdivision, combination or reclassification.

Whenever the Per Share Exercise Price is adjusted pursuant to subsection 3(a), the number of Warrant Shares issuable upon payment of the adjusted Per Share Exercise Price shall be adjusted to be equal to the product of the number of Warrant Shares issuable upon payment of the adjusted Per Share Exercise Price immediately prior to such adjustment multiplied by a fraction, the numerator of which shall be the Per Share Exercise Price payable immediately prior to such adjustment and the denominator which shall be the Per Share Exercise Price payable immediately after such adjustment.

In the event of any capital reorganization or reclassification, or any consolidation or merger to which the Company is a party other than a merger or consolidation in which the Company is the continuing corporation, or in case of any sale or conveyance to another entity of the property of the Company as an entirety or substantially as an entirety, the Holder of this Warrant shall have the right thereafter to receive on the exercise of this Warrant the kind and amount of securities, cash or other property which the Holder would have owned or have been entitled to receive immediately after such reorganization, reclassification, consolidation, merger, statutory exchange, sale or conveyance had this Warrant been exercised immediately prior to the effective date of such reorganization, reclassification, consolidation, merger, statutory exchange, sale or conveyance and in any such case, if necessary, appropriate adjustment shall be made in the application of the provisions set forth in this Section 3 with respect to the rights and interests thereafter of the Holder of this Warrant to the end that the provisions set forth in this Section 3 shall thereafter correspondingly be made applicable, as nearly as may reasonably be, in relation to any shares of stock or other securities or property thereafter deliverable on the exercise of this Warrant. The above provisions of this Subsection 3(e) shall similarly apply to successive reorganizations, reclassifications, consolidations, mergers, statutory exchanges, sales or conveyances. The issuer of any shares of stock or other securities or property thereafter deliverable on the exercise of this Warrant shall be responsible for all of the agreements and obligations of the Company hereunder. A


sale of all or substantially all of the assets of the Company for a consideration consisting primarily of securities shall be deemed a consolidation or merger for the foregoing purposes.

Whenever the Per Share Exercise Price is adjusted as provided in this Section 3 and upon any modification of the rights of a Holder of Warrants in accordance with this Section 3, the Chief Financial Officer, or equivalent officer, of the Company shall prepare a certificate setting forth the Per Share Exercise Price and the number of Warrant Shares after such adjustment or the effect of such modification, a brief statement of the facts requiring such adjustment or modification and the manner of computing the same and cause copies of such certificate to be mailed to the Holder.

Limited Transferability.

This Warrant may not be sold, transferred, assigned or hypothecated by the Holder except in compliance with the provisions of the Act and the applicable state securities "blue sky" laws, and is so transferable only upon the books of the Company which it shall cause to be maintained for such purpose. The Company may treat the registered Holder of this Warrant as he or it appears on the Company's books at any time as the Holder for all purposes. The Company shall permit any Holder of a Warrant or his duly authorized attorney, upon written request during ordinary business hours, to inspect and copy or make extracts from its books showing the registered holders of Warrants. All Warrants issued upon the transfer or assignment of this Warrant will be dated the same date as this Warrant, and all rights of the holder thereof shall be identical to those of the Holder.

Loss, etc., of Warrant. Upon receipt of evidence satisfactory to the Company of the loss, theft, destruction or mutilation of this Warrant, of indemnity reasonably satisfactory to the Company and, if requested by the Company, of a bond reasonably satisfactory to the Company, if lost, stolen or destroyed, and upon surrender and cancellation of this Warrant, if mutilated, the Company shall execute and deliver to the Holder a new Warrant of like date, tenor and denomination.

Status of Holder. This Warrant does not confer upon the Holder any right to vote or to consent to or receive notice as a stockholder of the Company, as such, in respect of any matters whatsoever, or any other rights or liabilities as a stockholder, prior to the exercise hereof.
