Hudson Technologies, Inc., incorporated under the laws of New York on January 11, 1991, is a refrigerant services company providing innovative solutions to recurring problems within the refrigeration industry. The Company's products and services are primarily used in commercial air conditioning, industrial processing and refrigeration systems, including (i) refrigerant sales, (ii) refrigerant management services consisting primarily of reclamation of refrigerants and (iii) RefrigerantSide® Services performed at a customer's site, consisting of system decontamination to remove moisture, oils and other contaminants. In addition, RefrigerantSide® Services include predictive and diagnostic services for industrial and commercial refrigeration applications, which are designed to predict potential catastrophic problems and identify inefficiencies in an operating system. The Company's Chiller Chemistry®, Chill Smart®, Fluid Chemistry™, and Performance Optimization are predictive and diagnostic service offerings. The Company operates through its wholly-owned subsidiary, Hudson Technologies Company. Unless the context requires otherwise, reference to the "Company", "Hudson", "we", "us", "our", or similar pronouns refer to Hudson Technologies, Inc. and its subsidiaries.

The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial statements and with the instructions of Regulation S-X. Accordingly, they do not include all the information and footnotes required by generally accepted accounting principles for complete financial statements. The financial information included in the quarterly report should be read in conjunction with the Company's audited financial statements and related notes thereto for the year ended December 31, 2009. Operating results for the nine month period ended September 30, 2010 are not necessarily indicative of the results that may be expected for the year ending December 31, 2010.

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.

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.

The carrying values of financial instruments including trade accounts receivable and accounts payable approximate fair value at September 30, 2010 and December 31, 2009, 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 September 30, 2010 and December 31, 2009.

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

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

For the nine months ended September 30, 2010 no one customer accounted for 10% or more of the Company's revenues. For the nine months ended September 30, 2009, one customer accounted for 10% 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.

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

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

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

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

The Company utilizes the asset and liability method for recording deferred income taxes, which provides for the establishment of deferred tax asset or liability accounts based on the difference between tax and financial reporting bases of certain assets and liabilities. The tax benefit associated with the Company's net operating loss carry forwards ("NOLs") is recognized to the extent that the Company is expected to recognize future taxable income. The Company assesses the recoverability of its deferred tax assets based on its expectation that it will recognize future taxable income and adjusts its valuation allowance accordingly. As of September 30, 2010, the net deferred tax asset is $4,120,000.

Certain states either do not allow or limit NOLs and as such the Company will be liable for certain state taxes. To the extent that the Company utilizes its NOLs, it will not pay tax on such income but may be subject to the federal alternative minimum tax. In addition, to the extent that the Company's net income, if any, exceeds the annual NOL limitation it will pay income taxes based on existing statutory rates. Moreover, as a result of a "change in control", as defined by the Internal Revenue Service, the Company's ability to utilize its existing NOLs is subject to certain annual limitations. The Company's NOLs are subject to annual limitations ranging from $1,300,000 to $2,500,000.

As a result of an Internal Revenue Service audit, the 2006 and prior federal tax years have been closed. The Company operates in many states throughout the United States and, as of September 30, 2010, the various states' statutes of limitations remain open for tax years subsequent to 2004.

If dilutive, common equivalent shares (common shares assuming exercise of options and warrants) utilizing the treasury stock method are considered in the presentation of diluted earnings per share. The reconciliation of shares used to determine net income (loss) per share is as follows (dollars in thousands, unaudited):

For the three month period ended September 30, 2010 and 2009 certain options and warrants aggregating 1,711,875 and 3,028,343 shares, respectively, have been excluded from the calculation of diluted shares, due to the fact that their effect would be anti-dilutive.

For the nine month period ended September 30, 2010 and 2009 certain options and warrants aggregating 1,474,375 and 3,028,343 shares, respectively, have been excluded from the calculation of diluted shares, due to the fact that their effect would be anti-dilutive.

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.

Several of the Company's accounting policies involve significant judgments, uncertainties and estimations. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results may differ from these estimates under different assumptions or conditions. To the extent that actual results differ from management's judgments and estimates, there could be a material adverse effect on the Company. On a continuous basis, the Company evaluates its estimates, including, but not limited to, those estimates related to its allowance for doubtful accounts, inventory reserves, valuation allowance for the deferred tax assets relating to its NOLs and commitments and contingencies. With respect to accounts receivable, the Company estimates the necessary allowance for doubtful accounts based on both historical and anticipated trends of payment history and the ability of the customer to fulfill its obligations. For inventory, the Company evaluates both current and anticipated sales prices of its products to determine if a write down of inventory to net realizable value is necessary. In determining the Company's valuation allowance for its deferred tax assets, the Company assesses its ability to generate taxable income in the future.

The Company participates in an industry that is highly regulated, changes in which could affect operating results. Currently the Company purchases virgin, hydrochlorofluorocarbon ("HCFC") and hydroflourocarbon ("HFC") refrigerants and reclaimable, primarily HCFC and chlorofluorocarbon ("CFC"), refrigerants from suppliers and its customers. Effective January 1, 1996, the Clean Air Act (the "Act") prohibited the production of virgin CFC refrigerants and limited the production of virgin HCFC refrigerants. Effective January 2004, the Act further limited the production of virgin HCFC refrigerants and federal regulations were enacted which impose limitations on the importation of certain virgin HCFC refrigerants. Additionally, effective January 1, 2010, the Act further limited the production of virgin HCFC refrigerants and additional federal regulations were enacted which impose further limitation on the use, production and importation of virgin HCFC refrigerants. Under the Act, production of certain virgin HCFC refrigerants is scheduled to be phased out during the period 2010 through 2020, and production of all virgin 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 and/or price for refrigerants, the Company could realize reductions in refrigerant processing and possible loss of revenues, which would have a material adverse affect on operating results.

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

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.

In January 2010, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2010-06, Fair Value Measurements and Disclosures (topic 820) - Improving Disclosures about Fair Value Measurements. ASU 2010-06 requires new disclosures regarding transfers in and out of the Level 1 and 2 and activity within Level 3 fair value measurements and clarifies existing disclosures of inputs and valuation techniques for Level 2 and 3 fair value measurements. ASU 2010-06 also includes conforming amendments to employers' disclosures about postretirement benefit plan assets. The new disclosures and clarifications of existing disclosures are effective for interim and annual reporting periods beginning after December 15, 2009, except for the disclosure of activity within Level 3 fair value measurements, which is effective for fiscal years beginning after December 15, 2010, and for interim periods within those years. There was no impact upon adoption of ASU 2010-06 on January 1, 2010 to our financial position or results of operations. We do not expect there will be an impact to our financial position or results of operations for the additional disclosure requirements in 2011.

In February 2010, the FASB issued ASU 2010-09, Subsequent Events (Topic 855) - Amendments to Certain Recognition and Disclosure Requirements. ASU 2010-09 requires an entity that is a Securities and Exchange Commission ("SEC") filer to evaluate subsequent events through the date that the financial statements are issued and removes the requirement that an SEC filer disclose the date through which subsequent events have been evaluated. ASC 2010-09 was effective upon issuance. The adoption of this standard had no effect on our results of operation or our financial position.

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 nine month period ended September 30, 2010 and 2009, the share-based compensation expense of $170,000 and $17,000, respectively, is reflected in general and administrative expenses in the consolidated statements of operations.

Share-based awards have historically been stock options issued pursuant to the terms of the Company's 1994, and 1997 stock option plans and the Company's 2004 and 2008 stock incentive plans, (collectively, the "Plans"), described below. The Plans may be administered by the Board of Directors or the Compensation and Stock Option Committee of the Board, or by another committee appointed by the Board from among its members as provided in the Plans. Presently, the Plans are administered by a committee consisting of non-employee directors. As of September 30, 2010, the Plans authorized the issuance of stock options to purchase 5,500,000 shares of the Company's common stock and, as of September 30, 2010 there were 2,654,000 shares of the Company's common stock available for issuance for future stock option grants or other stock based awards.

Stock options are awards, which allow the recipient to purchase shares of the Company's common stock at a fixed price, are typically granted at an exercise price equal to the Company's stock price at the date of grant. Typically, the Company's stock option awards have generally vested from immediately to two years from the grant date and have had a contractual term ranging from five to ten years.

For the nine month period ended September 30, 2010 and 2009, there were 155,000 and none, respectively, stock options issued by the Company. At September 30, 2010, there was $33,000 of unrecognized compensation cost related to non-vested previously granted option awards.

Effective October 31, 1994, the Company adopted an Employee Stock Option Plan ("1994 Plan") pursuant to which 725,000 shares of common stock were reserved for issuance upon the exercise of options designated as either (i) options intended to constitute incentive stock options ("ISOs") under the Internal Revenue Code of 1986, as amended, ("Code") or (ii) nonqualified options. ISOs could be granted under the 1994 Plan to employees and officers of the Company. Non-qualified options could be granted to

consultants, directors (whether or not they are employees), employees or officers of the Company. Effective November 1, 2004, the Company's ability to grant options under the 1994 Plan expired.

Effective July 25, 1997, the Company adopted its 1997 Employee Stock Option Plan, which was amended on August 19, 1999, ("1997 Plan") pursuant to which 2,000,000 shares of common stock were reserved for issuance upon the exercise of options designated as either (i) ISOs under the Code, or (ii) nonqualified options. ISOs could be granted under the 1997 Plan to employees and officers of the Company. Non-qualified options could be granted to consultants, directors (whether or not they are employees), employees or officers of the Company. Stock appreciation rights could also be issued in tandem with stock options. Effective September 11, 2007, the Company's ability to grant options or stock appreciation rights under the 1997 Plan expired.

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

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

Effective August 27, 2008, the Company adopted its 2008 Stock Incentive Plan ("2008 Plan") pursuant to which 3,000,000 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, restricted stock, deferred stock or other stock-based awards. ISOs may be granted under the 2008 Plan to employees and officers of the Company. Non qualified options, restricted stock, deferred stock or other stock-based awards may be granted to consultants, directors (whether or not they are employees), employees or officers of the Company. Stock appreciation rights may also be issued in tandem with stock options. Unless the 2008 Plan is sooner terminated, the ability to grant options or other awards under the 2008 Plan will expire on August 27, 2018.

ISOs granted under the 2008 Plan may not be granted at a price less than the fair market value of the common stock on the date of grant (or 110% of fair market value in the case of persons holding 10% or more of the voting stock of the Company). Nonqualified options granted under the 2008 Plan may not be granted at a price less than the fair market value of the common stock. Options granted under the 2008 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.

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

A summary of the status of the Company's Plans as of September 30, 2010 and December 31, 2009 and 2008 and changes for the years ending on those dates is presented below:

The intrinsic value of options exercised during the year ended December 31, 2009 was $2,000.

On April 17, 2008, Hudson amended its credit facility with Keltic Financial Partners, LLP ("Keltic") and secured participation from Bridge Healthcare Financial, LLC ("Bridge") to provide for borrowings up to $15,000,000 (the "Facility"). On September 23, 2009, Keltic advised the Company that it has assumed all of Bridge's rights under the Facility. The Facility consists of a revolving line of credit and two term loans, which expires on June 20, 2011. Advances under the revolving line of credit are limited to (i) 85% of eligible trade accounts receivable and (ii) 55% of eligible inventory. Advances available to Hudson under the A and B term loans may not exceed $2,500,000 and $4,500,000, respectively. At September 30, 2010, the Facility bore interest at 6.5%. Substantially all of Hudson's assets are pledged as collateral for its obligations under the Facility. In addition, among other things, the agreement restricts Hudson's ability to declare or pay any cash dividends on its capital stock. As of September 30, 2010, Hudson had in the aggregate $501,000 of borrowings outstanding and $6,968,000 available for borrowing under the revolving line of credit. In addition, as of September 30, 2010, the Company had $3,750,000 of borrowings outstanding under the A and B term loans.

In connection with the April 2008 amendment to the Facility, the Company issued 100,000 five-year common stock purchase warrants exercisable at $1.88 per share. The Company utilizes the Black-Scholes pricing model to compute the fair value of the 100,000 stock purchase warrants. The fair value of the warrants was $74,000 and is being amortized over the life of the Facility. As of September 30, 2010 there was $12,000 unamortized debt cost, which is included in other assets on the balance sheet.

On July 7, 2010, the Company sold 2,737,500 units, with the aggregate units consisting of 2,737,500 shares of the Company's common stock and warrants to purchase 1,368,750 shares, at a price of $2.00 per unit in a registered direct offering (the "2010 Offering") pursuant to the Company's Registration Statement on Form S-3, declared effective on September 5, 2008 (the "Shelf Registration"). The warrants issued as part of the 2010 Offering have an exercise price of $2.60 per share and are exercisable for a five-year period commencing on January 7, 2011. The net proceeds pursuant to the 2010 Offering was approximately $4,900,000. The value of the aggregate number of warrants issued pursuant to the 2010 Offering was approximately $920,000 and such amount was charged as a component of Stockholders' Equity to additional paid in capital.

Item 2 - Management's Discussion and Analysis of Financial Condition and Results of Operations

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

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

Sales of refrigerants continue to represent a significant portion of the Company's revenues. The Company's refrigerant sales are primarily HCFC and HFC based refrigerants and to a lesser extent CFC based refrigerants that are no longer manufactured. Under the Act, in 2010, future production of certain virgin HCFC refrigerants are scheduled to be phased out by the year 2020, and production of all virgin HCFC refrigerants is scheduled to be phased out by the year 2030. To the extent that the Company is unable to source refrigerants on commercially reasonable terms or at all, or the demand for refrigerants decreases, the Company's financial condition and results of operations could be materially adversely affected.

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

The Company focuses its sales and marketing efforts for its RefrigerantSide® Services on customers who the Company believes most readily appreciate and understand the value that is provided by its RefrigerantSide® Services offering. In pursuing its sales and marketing strategy, the Company offers its RefrigerantSide® Services to customers in the following industries; petrochemical, pharmaceutical, industrial power, manufacturing, commercial facility and property management and maritime. In addition, the Company has expanded its service offering outside of the United States through a strategic alliance with The Linde Group. The Company may incur additional expenses as it develops its RefrigerantSide® Services offering.

Revenues for the three month period ended September 30, 2010 were $7,996,000, an increase of $1,497,000 or 23% from the $6,499,000 reported during the comparable 2009 period. The increase in revenues was primarily attributable to an increase in refrigerant revenues of $1,458,000 and an increase in RefrigerantSide® Services revenues of $39,000. The increase in refrigerant revenues is primarily related to an increase in the number of pounds of certain refrigerants sold and to a lesser extent, an increase in the selling price per pound of certain refrigerants sold. The increase in RefrigerantSide® Services was attributable to an increase in the number of jobs completed, offset by a decrease in the average revenues per job completed when compared to the same period of 2009.

Cost of sales for the three month period ended September 30, 2010 was $6,192,000 an increase of $365,000 or 6% from the $5,827,000 reported during the comparable 2009 period. The increase in cost of sales was primarily due to the increase in the number of pounds of refrigerant sold. As a percentage of sales, cost of sales was 77% of revenues for 2010, compared to 90% in 2009. The decrease in cost of sales as a percentage of sales is due to a lower cost per pound of certain refrigerants sold.

Operating expenses for the three month period ended September 30, 2010 were $1,406,000 an increase of $465,000 or 49% from the $941,000 reported during the comparable 2009 period. The increase in operating expenses was primarily related to increased professional fees and payroll expenses. In the 2009 period, the Company recognized an insurance recovery of approximately $45,000 and in the 2010 period there were no recoveries, and in the 2009 period the Company recognized certain give-backs of management bonuses. The increase in professional fees is primarily related to an increase in accounting fees.

Other income (expense) for the three month period ended September 30, 2010 was ($218,000), compared to the ($368,000) reported during the comparable 2009 period. Other income (expense) includes interest expense of $224,000 and $368,000 for the comparable 2010 and 2009 periods, respectively. The decrease in interest expense is due to a reduction in outstanding borrowings in 2010 when compared to 2009.

Income tax (benefit) provision for the fiscal three month period ended September 30, 2010 and 2009 was ($20,000) and $21,000, respectively. The benefit reported for the three months ended September 30, 2010 represents a provision for pretax income utilizing statutory rates offset by a refund of prior year taxes. The provision for 2009 represents state and local taxes.

Net income for the three month period ended September 30, 2010 was $200,000, an increase of $858,000 from the net loss of ($658,000) reported during the comparable 2009 period, primarily due to increased revenues and gross profit, partially offset by increased operating expenses.

Revenues for the nine month period ended September 30, 2010 were $33,133,000 an increase of $11,735,000 or 55% from the $21,398,000 reported during the comparable 2009 period. The increase in revenues was primarily attributable to an increase in refrigerant revenues of $11,621,000 and an increase in RefrigerantSide® Services revenues of $114,000. The increase in refrigerant revenues is primarily related to an increase in the number of pounds of certain refrigerants sold. The increase in RefrigerantSide® Services was attributable to an increase in the average revenues per job completed offset to a lesser extent by a decrease in the number of jobs complete when compared to the same period of 2009.

Cost of sales for the nine month period ended September 30, 2010 was $26,455,000 an increase of $8,773,000 or 50% from the $17,682,000 reported during the comparable 2009 period. The increase in cost of sales was primarily due to the increase in the number of pounds of refrigerant sold. As a percentage of sales, cost of sales was 80% of revenues for 2010, a decrease from the 83% reported for the comparable 2009 period, primarily due to a lower cost per pound for certain refrigerants in 2010 as compared to the comparable 2009 period.

Operating expenses for the nine month period ended September 30, 2010 were $4,002,000 an increase of $607,000 or 18% from the $3,395,000 reported during the comparable 2009 period. The increase in operating expenses was primarily related to increased payroll expenses and professional fees. In the 2009 period, the Company recognized certain give-backs of management bonuses as well as having recognized an insurance recovery and there were no such events in the 2010 period. The increase in professional fees is primarily related to an increase in accounting fees.

Other income (expense) for the nine month period ended September 30, 2010 was ($791,000), compared to the ($1,138,000) reported during the comparable 2009 period. Other income (expense) includes interest expense of $797,000 and $1,138,000 for the comparable 2010 and 2009 periods, respectively. The decrease in interest expense is due to a reduction in outstanding borrowings in 2010 when compared to 2009.

Income tax provision (benefit) for the fiscal nine month period ended September 30, 2010 and 2009 was $628,000 and ($48,000), respectively. For 2010 the income tax provision of $628,000 was for federal and state income tax at statutory rates offset by a refund for prior years taxes. The tax benefits associated with the Company's NOLs are recognized to the extent that the Company is expected to recognize taxable income in future periods. The Company's NOLs are subject to annual limitations and the Company expects to incur certain state and/or federal alternative minimum taxes for the foreseeable future.

Net income for the nine month period ended September 30, 2010 was $1,257,000 an increase of $2,026,000 from the ($769,000) net loss reported during the comparable 2009 period, primarily due to increased revenues and gross profit, partially offset by increased operating expenses.

At September 30, 2010, the Company had working capital, which represents current assets less current liabilities of $12,435,000, an increase of $3,066,000 from the working capital of $9,369,000 at December 31, 2009. The increase in working capital is primarily attributable to the proceeds from the 2010 Offering offset by the reclassification of $3,000,000 of term loans from long term to short term to reflect the scheduled expiration of the Keltic Facility on June 26, 2011.

Inventory and trade receivables are principal components of current assets. At September 30, 2010, the Company had inventories of $12,789,000 a decrease of $3,621,000 from the $16,410,000 at December 31, 2009. 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 based refrigerants, which are no longer being manufactured, or non-CFC based refrigerants. At September 30, 2010, the Company had trade receivables, net of allowance for doubtful accounts of $4,207,000, an increase of $2,613,000 from the $1,594,000 at December 31, 2009. The Company's trade receivables are concentrated with various wholesalers, brokers, contractors and end-users within the refrigeration industry that are primarily located in the continental United States.

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

Net cash provided by operating activities for the nine month period ended September 30, 2010, was $3,628,000 compared with net cash provided by operating activities of $3,516,000 for the comparable 2009 period. Net cash provided by operating activities for the 2010 period was primarily attributable to net income, a decrease in inventory, and an increase in accounts payable, offset by an increase in accounts receivable.

Net cash used by investing activities for the nine month period ended September 30, 2010, was $273,000 compared with net cash used by investing activities of $380,000 for the comparable 2009 period. The net cash used by investing activities for the 2010 period was primarily related to investment in general purpose equipment for the Company's Champaign, Illinois facility.

Net cash provided by financing activities for the nine month period ended September 30, 2010, was $426,000 compared with net cash used by financing activities of $1,912,000 for the comparable 2009 period. The net cash provided by financing activities for the 2010 period was primarily due to the proceeds from the 2010 Offering offset by repayments of short term debt.

At September 30, 2010, the Company had cash and cash equivalents of $4,080,000. The Company continues to assess its capital expenditure needs. The Company may, to the extent necessary, continue to utilize its cash balances to purchase equipment primarily for its operations. The Company estimates that the total capital expenditures for 2010 will be approximately $600,000.

The following is a summary of the Company's significant contractual cash obligations for the periods indicated that existed as of September 30, 2010 (in 000's):

____________

On June 26, 2007, a subsidiary of Hudson entered into the Facility with Keltic and on April 17, 2008, the Facility was amended to secure the participation of Bridge Healthcare Financial, LLC ("Bridge") and to provide for borrowings of up to $15,000,000. On September 23, 2009, Keltic advised the Company that it had assumed all of Bridge's rights under the Facility. The Facility consists of a revolving line of credit and two term loans, which expires on June 20, 2011. Advances under the revolving line of credit are limited to (i) 85% of eligible trade accounts receivable and (ii) 55% of eligible inventory. Advances available to Hudson under the A and B term loans may not exceed $2,500,000 and $4,500,000, respectively. At September 30, 2010, the Facility bore interest at 6.5%. Substantially all of Hudson's assets are pledged as collateral for its obligations under the Facility. In addition, among other things, the loan agreement restricts Hudson's ability to declare or pay any cash dividends on its capital stock. As of September 30, 2010, Hudson had $501,000 of borrowings outstanding and $6,968,000 available for borrowing under the revolving line of credit. In addition, as of September 30, 2010, Hudson had $3,750,000 of borrowings outstanding under the A and B term loans.

In connection with the April 2008 amendment to the Facility, the Company issued an aggregate of 100,000 five-year common stock purchase warrants exercisable at $1.88 per share. The fair value of the warrants was $74,000 and such amount is amortized over the life of the Facility.

On March 20, 2009, the Company borrowed $1,000,000 from a non-affiliate for a period of nine months at an interest rate of 10% per annum. The borrowing is subordinated to the Facility. On September 30, 2009, the due date of the loan was extended to September 30, 2010. As of September 30, 2010 the loan was repaid and there are no further obligations under the loan.

On July 31, 2009, Hudson entered into a Placement Agent Agreement with an investment banking firm, (the "Placement Agent"), engaging the Placement Agent to act as placement agent for a registered direct offering under the Shelf Registration to sell, on a best efforts basis, 3,870,000 shares of the Company's common stock at a sale price of $1.15 per share (the "Offering").

A closing of the Offering was held on August 5, 2009, at which time, the Company sold 1,470,000 shares of its common stock at $1.15 per share and received net proceeds of approximately $1,400,000 and no other closings were completed. The Placement Agent received compensation from the Company of $101,000 and a warrant to purchase 73,500 shares of common stock at an exercise price of $1.4375 per share, plus reimbursement of its expenses of $56,000. The estimated fair value of the warrant was approximately $48,000 and such warrant was charged to additional paid in capital as compensation expense to the Placement Agent. As of October 1, 2009, the Company discontinued, and ceased pursuing future sales under, the Offering.

In September, 2009, the Company issued an aggregate of 32,173 shares of its common stock to certain vendors and the Company expensed approximately $44,000 as professional fees for these services.

On July 7, 2010, the Company sold 2,737,500 units, with the aggregate units consisting of 2,737,500 shares of the Company's common stock and warrants to purchase 1,368,750 shares, at a price of $2.00 per unit pursuant to the Company's Shelf Registration and received net proceeds of approximately $4,900,000. The warrants issued as part of the 2010 Offering have an exercise price of $2.60 per share and are exercisable for a five-year period commencing on January 7, 2011. The value of the aggregate number of warrants issued pursuant to the 2010 Offering was approximately $920,000 and such amount was charged as a component of Stockholders' Equity to additional paid in capital.

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

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

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

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

The Company's financial performance and its ability to sell refrigerants is in part dependent on its ability to obtain sufficient quantities of virgin, non-CFC based refrigerants, and of reclaimable CFC and non-CFC based, refrigerants from manufacturers, wholesalers, distributors, bulk gas brokers and from other sources within the air conditioning, refrigeration and automotive aftermarket industries, and on corresponding demand for refrigerants. The Company's refrigerant sales include CFC based refrigerants, which are no longer manufactured. Additionally, the Company's refrigerant sales include non-CFC based refrigerants, including HCFC and HFC refrigerants, which are the most widely used refrigerants. Effective January 1, 1996, the Act limits the production of virgin HCFC refrigerants, which production was further limited in January 2004. Federal regulations enacted in January 2004 also imposed limitations on the importation of certain virgin HCFC refrigerants. In addition, effective January 1, 2010, the Act further limited the production of virgin HCFC refrigerants and additional federal regulations were enacted which imposed further limitations on the use, production and importation of certain virgin HCFC refrigerants. Under the Act, production of certain virgin HCFC refrigerants is scheduled to be phased out by the year 2020 and production of all virgin HCFC refrigerants is scheduled to be phased out by the year 2030. The limitations imposed by and under the Act may limit supplies of virgin refrigerants for the foreseeable future or cause a significant increase in the price of virgin HCFC refrigerants. To the extent the Company is unable to source sufficient quantities of virgin or reclaimable refrigerants in the future, or resell refrigerants at a profit, the Company's financial condition and results of operations would be materially adversely affected.

For the nine months ended September 30, 2010 no one customer accounted for 10% or more of the Company's revenues. For the nine months ended September 30, 2009, one customer accounted for 10% of the Company's revenues.

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

The Company's operating results vary from period to period as a result of weather conditions, requirements of potential customers, non-recurring refrigerant and service sales, availability and price of refrigerant products (virgin or reclaimable), changes in reclamation technology and regulations, timing in introduction and/or retrofit or replacement of CFC and non CFC based refrigeration equipment, the rate of expansion of the Company's operations, and by other factors. The Company's business is seasonal in nature with peak sales of refrigerants occurring in the first half of each year. During past years, the seasonal decrease in sales of refrigerants has resulted in losses particularly in the fourth quarter of the year. In addition, during 2009, the Company experienced decreases in sales due, in part, to unseasonably cool weather throughout the spring and summer months, which adversely impacted demand for refrigerants. Delays or inability in securing adequate supplies of refrigerants at peak demand periods, lack of refrigerant demand, increased expenses, declining refrigerant prices and a loss of a principal customer could result in significant losses. There can be no assurance that the foregoing factors will not occur and result in a material adverse effect on the Company's financial position and significant losses. The Company believes that there is a similar seasonal element to RefrigerantSide® Service revenues as refrigerant sales. The Company is continuing to assess its RefrigerantSide® Service revenues seasonal trend.

In January 2010, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2010-06, Fair Value Measurements and Disclosures (topic 820) - Improving Disclosures about Fair Value Measurements. ASU 2010-06 requires new disclosures regarding transfers in and out of the Level 1 and 2 and activity within Level 3 fair value measurements and clarifies existing disclosures of inputs and valuation techniques for Level 2 and 3 fair value measurements. ASU 2010-06 also includes conforming amendments to employers' disclosures about postretirement benefit plan assets. The new disclosures and clarifications of existing disclosures are effective for interim and annual reporting periods beginning after December 15, 2009, except for the disclosure of activity within Level 3 fair value measurements, which is effective for fiscal years beginning after December 15, 2010, and for interim periods within those years. There was no impact upon adoption of ASU 2010-06 on January 1, 2010 to our financial position or results of operations. We do not expect there will be an impact to our financial position or results of operations for the additional disclosure requirements in 2011.

In February 2010, the FASB issued ASU 2010-09, Subsequent Events (Topic 855) - Amendments to Certain Recognition and Disclosure Requirements. ASU 2010-09 requires an entity that is a Securities and Exchange Commission ("SEC") filer to evaluate subsequent events through the date that the financial statements are issued and removes the requirement that an SEC filer disclose the date through which subsequent events have been evaluated. ASC 2010-09 was effective upon issuance. The adoption of this standard had no effect on our results of operation or our financial position.

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

There were no changes in the Company's internal control over financial reporting (as defined in Rule 13a-15(f) of the Exchange Act) in the quarter ended September 30, 2010 that materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting.
