In the opinion of management, all estimates and adjustments considered necessary for a fair presentation have been included and all such adjustments were normal and recurring.



Consolidation



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



Reclassification



Certain account balances have been reclassified for comparative purposes.



Fair value of financial instruments



The carrying values of financial instruments including trade accounts receivable and accounts payable approximate fair value at March 31, 2006, because of the relatively short maturity of these instruments.  The carrying value of short-and long-term debt approximates fair value, based upon quoted market rates of similar debt issues, as of March 31, 2006 and December 31, 2005.



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 receivable 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.  The carrying value of the Company's accounts receivable are reduced by the established allowance for doubtful accounts.  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 three month period ended March 31, 2006, no customer accounted for 10% or more of the Company's revenues.  During the three month period ended March 31, 2005, one customer accounted for 23% of the Company's revenues.



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



Cash and cash equivalents



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



Inventories



Inventories, consisting primarily of 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 customer is fixed.  License fees are recognized over the period of the license based on the respective performance measurements associated with the license.  Royalty revenues are recognized when earned.  Cost of sales is recorded based on the cost of products shipped or services performed and related direct operating costs of the Company's facilities.  To the extent that the Company charges its customers shipping fees such amounts are included as a component of revenue and the corresponding costs are included as a component of cost of sales.



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

|                                   | ======= | =======



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 prior period losses.  The tax benefit associated with the Company's net operating loss carry forwards is recognized to the extent that the Company is expected to recognize net income.  Certain states either do not allow or limit net operating loss carry forwards and as such the Company will be liable for certain state taxes even though for federal tax purposes the Company has net operating loss carry forwards and will not pay federal taxes.



Income per common and equivalent shares



Income per common share, Basic, is calculated based on the net income for the period divided by the weighted average number of shares outstanding.  If dilutive, common equivalent shares (common shares assuming exercise of options and warrants) utilizing the treasury stock method are considered in the presentation of dilutive earnings per share.  For the quarter ended March 31, 2006, the number of common equivalent shares included and excluded in the calculation of dilutive income per common share were 1,461,740 and 1,142,545, respectively.  In 2005, the effect of equivalent shares was not dilutive.





Estimates and risks



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



The Company participates in an industry that is highly regulated, changes in which could affect operating results.  Currently the Company purchases virgin, non chlorofluorocarbon ("CFC") based, and reclaimable, primarily CFC based, refrigerants from suppliers and its customers.  Effective January 1, 1996, the Clean Air Act (the "Act") prohibited the production of CFC refrigerants and limited the production of hydrochlorofluorocarbons ("HCFC") refrigerants.  Additionally, effective January 2004, the Act further limited the production of HCFC refrigerants and federal regulations were enacted which impose limitations on the importation of certain virgin HCFC refrigerants.  Under the Act, production of certain HCFC refrigerants is scheduled to be phased out by the year 2020, and production of all HCFC refrigerants is scheduled to be phased out by 2030.  Notwithstanding the limitations under the Act, the Company believes that sufficient quantities of new and used refrigerants will continue to be available to it at a reasonable cost for the foreseeable future.  To the extent that the Company is unable to source sufficient quantities of refrigerants or is unable to obtain refrigerants on commercially reasonable terms or experiences a decline in demand for refrigerants, the Company could realize reductions in refrigerant processing and possible loss of revenues, which would have a material adverse affect on its operating results.



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



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



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



Stock options



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 net income 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



As of January 1, 2006, the Company adopted, utilizing the modified prospective method, the Financial Accounting Standards Board ("FASB") revision of FASB statement No. 123, ("Revised SFAS 123") which requires that the cost resulting from all share-based payment transactions be recognized in the financial statements.  Revised SFAS 123 establishes fair value as the measurement objective in accounting for share-based payment arrangements (see "Note 2").

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



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



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



Note 2- Share-Based Compensation



Share-based compensation represents the cost related to share-based awards, typically stock options, granted to employees, non-employees, officers and directors.  Share-based compensation is measured at grant date, based on the estimated fair value of the award, and such amount is charged to compensation expense on a straight-line basis (net of estimated forfeitures) over the requisite service period.  For the quarter ended March 31, 2006, the share-based compensation expense of $87,000 is reflected in general and administrative expenses in the consolidated statement of income.



Share-based awards have historically been stock options issued pursuant to the terms of the Company's 1994, 1997 and 2004 stock option plans (the "Plans").  The Plans are administered by the Compensation Committee and the Board of Directors.  As of March 31, 2006, the Plans authorized the issuance of stock options to purchase 4,500,000 shares of the Company's common stock and, as of March 31, 2006, there were 1,816,237 shares of the Company's common stock available for issuance for future stock option grants.



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



During the three month period ended March 31, 2006, the Company issued 160,000 stock options and the fair value of these awards was $140,000.  Total unrecognized compensation cost related to non-vested previously granted option awards of 352,370 was $255,000 which is expected to be recognized over a weighted -average period of approximately 2 years.



The following weighted-average assumptions were used in determining fair values of share-based award are as follows:





|Period ended March 31, | 2006                   
|---------------------- | -----------------------

Item 2 - 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-QSB constitute "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995.  Such forward-looking statements involve a number of known and unknown risks, uncertainties and other factors which may cause the actual results, performance or achievements of the Company to be materially different from any future results, performance or achievements expressed or implied by such forward-looking statements.  Such factors include, but are not limited to, changes in the demand and price for refrigerants (including unfavorable market conditions adversely affecting the demand for, and the price of refrigerants), the Company's ability to source CFC and non CFC based refrigerants, regulatory and economic factors, seasonality, competition, litigation, the nature of supplier or customer arrangements 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 this report and in the Company's other periodic reports filed with the Securities and Exchange Commission.  The words "believe", "expect", "anticipate", "may", "plan", "should" and similar expressions identify forward-looking statements.  Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date the statement was made.



Critical Accounting Policies



The Company's discussion and analysis of its financial condition and results of operations are based upon its consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States.  The preparation of these financial statements requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosure of contingent assets and liabilities.  Several of the Company's accounting policies involve significant 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 estimates, there could be a material adverse effect on the Company.  On a continuous basis, the Company evaluates its estimates, including, but not limited to, those estimates related to its allowance for doubtful accounts, inventory reserves 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



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



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



Sales of refrigerants continue to represent a majority of the Company's revenues.  Certain of the Company's refrigerant sales are CFC based refrigerants, which are no longer manufactured.  The demand for CFC based refrigerants has and will continue to decrease as equipment that utilize other chemical based refrigerants displace those units that utilize CFC based refrigerants, particularly in the automotive aftermarket segment of the refrigerant sales industry.  The Company has increased its refrigerant

sales from non CFC based refrigerants, including HCFC refrigerants.  Effective January 1, 1996, the Act limits the production of HCFC refrigerants, which production was further limited in January 2004.  Federal regulations enacted in January 2004 also imposed limitations on the importation of certain HCFC refrigerants.  Under the Act, production of certain HCFC refrigerants is scheduled to be phased out by the year 2020, and production of all HCFC refrigerants is scheduled to be phased out by the year 2030.  To the extent that the Company is unable to source CFC based or non CFC based refrigerants on commercially reasonable terms or at all, or the demand for CFC based or non CFC based refrigerants decreases, the Company's financial condition and results of operations could be materially adversely affected.



Results of Operations



Three month period ended March 31, 2006 as compared to three month period ended March 31, 2005



Revenues for the three month period ended March 31, 2006 were $6,906,000, an increase of $2,324,000 or 51% from the $4,582,000 reported during the comparable 2005 period.  The increase in revenues was primarily attributable to an increase in refrigerant revenues of $1,859,000 and an increase in RefrigerantSide® Services revenues of $465,000.  The increase in refrigerant revenues of $1,859,000 is due to an increase in volume of $2,225,000 offset by a reduction in the price of certain refrigerants sold of $366,000.  The increase in RefrigerantSide® Services revenues of $465,000 was primarily attributed to an increase in the overall size of jobs performed in the aggregate amount of $300,000 and an increase in the number of jobs performed in the aggregate amount of $165,000.



Cost of sales for the three month period ended March 31, 2006 was $5,180,000 an increase of $2,044,000 or 65% from the $3,136,000 reported during the comparable 2005 period.  The increase in cost of sales was primarily due to the volume of refrigerants sold.  As a percentage of sales, cost of sales were 75% of revenues for the 2006 period, an increase from the 68% reported for the comparable 2005 period.  The increase in cost of sales as a percentage of revenues was primarily attributable to the decrease in the sales price and an increase in the materials cost of certain refrigerants sold resulting in lower gross profit margins on the sale of those products.



Operating expenses for the three month period ended March 31, 2006 were $1,373,000, an increase of $216,000 or 19% from the $1,157,000 reported during the comparable 2005 period.  The increase was primarily attributable to an increase in selling and compensation expense related to the adoption of SFAS 123(r).



Other income (expense) for the three month period ended March 31, 2006 was $(101,000), compared to the $(66,000) reported during the comparable 2005 periods.  Other income (expense) includes interest expense of $103,000 and $66,000 for the 2006 and 2005 periods, respectively.  The increase in interest expense is primarily attributed to an increase in borrowings in 2006.



Income taxes for the three months ended March 31, 2006 of $5,000 were recognized for states that either do not allow or have limitations on net operating loss carry forwards.  No income taxes for the three months ended March 31, 2005 were recognized.  During the 2006 and 2005 periods, no federal income taxes were recognized on the income before taxes of $247,000 and $223,000, respectively, due to the utilization of net operating loss carry forwards from prior periods.  The Company recognized a reserve allowance against the deferred tax benefit for the 2003 and prior losses.  The tax benefits associated with the Company's net operating loss carry forwards is recognized to the extent that the Company is expected to recognize net income.  A portion of the Company's net operating loss carry forwards are subject to annual limitations.  Limitations on the amount of the Company's net operating loss carry forwards, and on the annual limitations, could occur in the future upon the occurrence of certain events including, without limitation, a change in control of the Company.



Net income for the three month period ended March 31, 2006 was $247,000, an increase of $24,000 from the $223,000 net income reported during the comparable 2005 period.  The increase in net income was primarily attributed to the increase in volume in refrigerant sales and an increase in RefrigerantSide® Services offset by increased compensation costs primarily as a result of the adoption of SFAS 123(r).



Liquidity and Capital Resources



At March 31, 2006, the Company had a working capital, which represents current assets less current liabilities, of approximately $4,161,000, an increase of $274,000 from the working capital of $3,887,000 at December 31, 2005.  The increase in working capital is primarily attributable to operating results.



Principal components of current assets are inventory and trade receivables.  At March 31, 2006, the Company had inventories of $5,292,000, a decrease of  $853,000 or 14% from the $6,145,000 at December 31, 2005.  The decrease in the inventory balance is due to the timing and availability of inventory purchases and the sale of refrigerants.  The Company's ability to sell and replace its inventory on a timely basis and the prices at which it can be sold are subject, among other things, to current market conditions and the nature of supplier or customer arrangements and the Company's ability to source CFC refrigerants, which are no longer being

manufactured, or non-CFC refrigerants (see "Reliance on Suppliers and Customers" and "Seasonality and Fluctuations in Operating Results").  At March 31, 2006, the Company had trade receivables, net of allowance for doubtful accounts, of $3,490,000, an increase of $1,661,000 or 91% from the $1,829,000 at December 31, 2005.  The Company's trade receivables are concentrated with various wholesalers, brokers, contractors and end-users within the refrigeration industry that are primarily located in the continental United States.



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



Net cash used by operating activities for the three month period ended March 31, 2006, was $268,000 compared with net cash provided by operating activities of $1,087,000 for the comparable 2005 period.  The net cash used by operating activities was primarily attributable to the increase in accounts receivable offset in part by a decrease in inventories.



Net cash used by investing activities for the three month period ended March 31, 2006, was $37,000 compared with net cash used by investing activities of $62,000 for the prior comparable 2005 period.  The net cash used by investing activities for the 2006 period was primarily related to investment in general purpose equipment.



Net cash used by financing activities for the three month period ended March 31, 2006, was $15,000 compared with net cash used by financing activities of $1,093,000 for the comparable 2005 period.  The net cash used by financing activities for the 2005 period primarily consisted of repayment of short-term debt.  The net cash used by financing activities for the 2006 period was due to the repayment of long-term debt partially offset by proceeds from short-term debt.



At March 31, 2006, the Company had cash and cash equivalents of $314,000.  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 reclamation facility, and to a lesser extent in support of its RefrigerantSide® Services.  The Company estimates that capital expenditures during 2006 may range from approximately $500,000 to $700,000.



On May 30, 2003, Hudson entered into a credit facility with Keltic Financial Partners, LLP ("Keltic") which provides for borrowings of up to $5,000,000.  The facility consists of a revolving line of credit and a term loan and expires on May 30, 2007.  Advances under the revolving line of credit may not exceed $4,600,000 and are limited to (i) 85% of eligible trade accounts receivable and (ii) 50% of eligible inventory.  Advances available to Hudson under the term loan may not exceed $400,000.  The facility bears interest at a rate equal to the greater of the prime rate plus 1.0 %, or 6.5%, and was 8.75% at March 31, 2006.  Substantially all of Hudson's assets are pledged as collateral for its obligations to Keltic under the credit facility.  In addition, among other things, the agreements restrict Hudson's ability to declare or pay any cash dividends on its capital stock.  As of March 31, 2006, Hudson had in the aggregate $1,263,000 of borrowings outstanding and $3,337,000 available for borrowing under the Keltic revolving line of credit, respectively.  In addition, the Company had $353,000 of borrowings outstanding under its term loan with Keltic.



On March 31, 2004, the holders of the Series A Preferred Stock converted all of their shares of the Series A Preferred Stock into Common Stock at a conversion price of $0.79 per share.  Upon conversion the holders of the Series A Preferred Stock received 16,397,468 shares of Common Stock (the "Conversion Shares").  In connection with the original purchase of the Company's Series A Preferred Stock, the holders of the Preferred Stock were provided certain registration, preemptive and tag along rights and such rights continue to be held by the holders of the Conversion Shares.  The holders of the Conversion Shares have the right, for as long as they hold at least thirty-five (35%) percent in the aggregate of the Conversion Shares, or at least 5,739,114 Conversion Shares, to nominate up to two individuals to become members of the Company's Board of Directors, or at their option, to designate up to two advisors to the Company's Board of Directors who will attend and observe meetings of the Board of Directors.  The holders of the Conversion Shares have the right, for as long as they hold at least twenty (20%) percent, or at least 3,279,494 Conversion Shares, but less than thirty-five (35%) percent in the aggregate of the Conversion Shares, to nominate one individual to become a member of the Company's Board of Directors, or at their option, to designate one advisor to the Company's Board of Directors who will attend and observe meetings of the Board of Directors.



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



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



Inflation



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



Reliance on Suppliers and Customers



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



During the three month period ended March 31, 2006, no customer accounted for 10% or more of the Company's revenues.  During the three month period ended March 31, 2005, one customer accounted for 23% 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, 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 losses during the second half of the year.  Delays or inability in securing adequate supplies of refrigerants at peak demand periods, lack of refrigerant demand, increased expenses, declining refrigerant prices and a loss of a principal customer could result in significant losses.  There can be no assurance that the foregoing factors will not occur and result in a material adverse effect on the Company's financial position and significant losses.  The Company believes that there is a similar seasonal element to RefrigerantSide® Service revenues as refrigerant sales.  The Company is continuing to assess its RefrigerantSide® Service revenues seasonal trend.



Item 3 - Controls and Procedures



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 as of March 31, 2006.  Based on that evaluation, the CEO and CFO have concluded that the Company's disclosure controls and procedures are effective to provide reasonable assurance that: (i) information required to be disclosed by the Company in reports that it files or submits under the Securities Exchange Act of 1934 is accumulated and communicated to the Company's management, including the CEO and CFO, as appropriate to allow timely decisions regarding required disclosure by the Company; and (ii) 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.  During the quarter ended March 31, 2006, there were no changes in the Company's internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, its internal control over financial reporting.
