        Hudson Technologies Reports First Quarter 2003 Results

    PEARL RIVER, N.Y.--(BUSINESS WIRE)--May 14, 2003--Hudson
Technologies, Inc. (Nasdaq: HDSN), a leading refrigerant services
Company specializing in proprietary on-site decontamination services
for large comfort and process cooling systems, today announced results
for the first quarter ended March 31, 2003.
    Revenues for the first quarter ended March 31, 2003, totaled
$5,677,000, versus $6,111,000 for the same period in 2002. For the
first quarter of 2003, the Company reported an operating loss of
$234,000 compared to an operating loss of $592,000 for the same period
last year. The Company reported a net loss of $422,000 and, after
non-cash charges of $218,000 for payment-in-kind preferred stock
dividends, a net loss per common share of $0.12. For the same period
in 2002, the Company reported a net loss of $448,000 and, after
non-cash charges of $197,000 for payment-in-kind preferred stock
dividends, a net loss per common share of $0.13.
    The Company's first-quarter 2002 results included a non-recurring
gain of $232,000 attributable to proceeds from the prepayment of a
note receivable from Environmental Support Solutions, Inc. The
Company's first-quarter 2003 results include approximately $100,000 of
non-recurring finance charges related to the Company's credit facility
and amortization of original issue discount associated with its
outstanding convertible debt, which resulted in a $330,000 reduction
in total other income for the first quarter of 2003, as compared to
2002.
    Kevin J. Zugibe, chairman and chief executive officer, commented,
"We reduced our operating loss by more than half for the quarter,
demonstrating the progress that Hudson is making. As expected,
revenues declined from last year's first quarter due to the
restructuring of the Company's sales and marketing division. Moreover,
as a result of the cost containment measures we began to implement
last year, our gross profit margin increased to 29% as a percent of
sales from 23% in the previous period, while sales and marketing
expense decreased to 9% as a percent of sales from 11%. This resulted
in a $358,000 reduction in our operating loss in the 2003 period.
    "We have been continuing our work with the consulting firm we
retained earlier this year to develop a plan for achieving profitable
growth in our RefrigerantSide(R) Services business. Our goals are to
improve our sales and marketing strategies and streamline our service
offering so that we reach our target market of large, industrial
end-users as effectively as possible while achieving profitable
operations as quickly as possible."
