                                 PROXY STATEMENT

                            HUDSON TECHNOLOGIES, INC.

                         ANNUAL MEETING OF SHAREHOLDERS
                         TO BE HELD ON DECEMBER 19, 2003

            This proxy statement is furnished in connection with the
solicitation of proxies by the Board of Directors of Hudson Technologies, Inc.
(the "Company") for use at the Annual Meeting of Shareholders (the "Annual
Meeting") to be held on Friday, December 19, 2003, and including any adjournment
or adjournments thereof, for the purposes set forth in the accompanying Notice
of Meeting.

            Management intends to mail this proxy statement and the accompanying
form of proxy to shareholders on or about November 26, 2003.

            Proxies in the accompanying form, duly executed, returned to the
management of the Company and not revoked, will be voted at the Annual Meeting.
Any proxy given pursuant to such solicitation may be revoked by the shareholder
at any time prior to the voting of the proxy by a subsequently dated proxy, by
written notification to the Secretary of the Company, or by personally
withdrawing the proxy at the Annual Meeting and voting in person.

            The address and telephone number of the principal executive offices
of the Company are:

275 North Middletown Road
Pearl River, New York 10965
Telephone No.: (914) 735-6000

                       OUTSTANDING STOCK AND VOTING RIGHTS

            Only shareholders of record at the close of business on November 21,
2003 (the "Record Date") are entitled to notice of and to vote at the Annual
Meeting. As of the Record Date, there were issued and outstanding 5,239,920
shares of the Company's common stock, par value $.01 per share ("Common Stock")
and 125,085 shares of the Company's Series A Preferred Stock, par value $.01 per
share ("Preferred Stock"), the only classes of voting securities of the Company.
Each share of Common Stock entitles the holder thereof to one vote on each
matter submitted to a vote at the Annual Meeting. The holders of the shares of
Preferred Stock vote together with holders of Common Stock as one class except
that only holders of the Preferred Stock are entitled to vote on the election of
the two directors appointed by them pursuant to the terms of the Company's
Certificate of Designation relating to the Preferred Stock (the "Series A
Directors"). Messrs. Robert L. Burr and Robert M. Zech are the two Series A
Directors who have previously been elected by the holders of the Preferred
Stock. Mr. Robert Zech's affiliation with the holders of the Preferred Stock
ended in October 2001. Mr. Zech's term as a director expired in 2002 and,
although he was then no longer affiliated with the holders of the Preferred
Stock, Mr. Zech was elected by the shareholders to a two year term on the
Company's board of directors at the Company's December 2002 annual meeting. In
July, 2003,



Mr. Zech again became affiliated with the holders of the Preferred Stock and,
effective July 25, 2003 Mr. Zech vacated his position as an outside director of
the board and has been designated by the holders of the Preferred Stock to fill
the second board position reserved for the Preferred shareholders until the
expiration of that term in 2004. Each share of Preferred Stock entitles the
holder to such number of votes per share on each such action as shall equal the
number of shares of Common Stock (including fractions of a share) into which
each share of Preferred Stock is then convertible provided, however, that, in
determining the number of votes per share of Series A Preferred Stock, the
Conversion Price shall be the higher of (a) the Conversion Price then in effect
(which is currently approximately 90.909 shares of Common Stock for each share
of Preferred Stock), or (b) $1.78. Accordingly, based upon the $1.78 Conversion
Price established for voting purposes only, each share of Preferred Stock
entitles the holder to vote 56.180 shares of Common Stock, or an aggregate of
7,027,275 votes.

                                VOTING PROCEDURES

            At the Annual Meeting, Mr. Burr will be elected by a plurality of
the votes cast by holders of the Preferred Stock in person or, provided a quorum
of the Preferred Stock is present, at the Annual Meeting. All other directors
will be elected by a plurality of the votes cast by the holders of Common Stock
and Preferred Stock, voting together as one class, in person or represented by
proxy at the Annual Meeting, provided a quorum is present at the meeting. All
other matters to be acted upon at the meeting, will be decided by the majority
of the votes cast by the holders of the shares of Common Stock and Preferred
Stock, voting together as one class, present in person or represented by proxy
at the Annual Meeting, provided a quorum is present. For purposes of the
election of Mr. Burr by holders of the Preferred Stock, a quorum will be present
at the Annual Meeting if holders of a majority of the votes represented by
holders of the Preferred Stock are present in person or represented by proxy at
the Annual Meeting. With respect to all other matters, a quorum will be present
at the Annual Meeting if the holders of a majority of the outstanding aggregate
votes represented by holders of the Common Stock and the Preferred Stock as of
the Record Date are present in person or represented by proxy. Votes will be
counted and certified by one or more Inspectors of Election who are expected to
be employees of Continental Stock Transfer & Trust Company, the Company's
transfer agent.

            In accordance with applicable law, abstentions and "broker
non-votes" (i.e., proxies from brokers or nominees indicating that such persons
have not received instructions from the beneficial owners or other persons
entitled to vote shares as to a matter with respect to which the brokers or
nominees do not have discretionary power to vote) will be treated as present for
purposes of determining the presence of a quorum. Based upon the Company's
understanding of the requirements of the law of the State of New York and the
Certificate of Incorporation and By-laws, as amended (the "By-laws"), of the
Company, "votes cast" at a meeting of shareholders by the holders of shares
entitled to vote are determinative of the outcome of the matter to be voted on.
Failures to vote, broker non-votes and abstentions will not be considered "votes
cast."

            Proxies will be voted in accordance with the instructions thereon.
Unless otherwise stated, all shares represented by such proxy will be voted as
instructed. Proxies may be revoked as noted above.


                                      -2-


            The holders of the Preferred Stock represent approximately 57% of
the Common Stock and the Preferred Stock, voting together as a single class,
outstanding as of the Record Date and eligible to vote at the Annual Meeting,
have indicated their intention to vote in favor of the nominees for directors
indicated below.

                              ELECTION OF DIRECTORS

            The Company's By-laws provide that the Board of Directors (the
"Board") is divided into two classes. Each class is to have a term of two years
(the term of each class expiring in successive years) and is to consist, as
nearly as possible, of one-half of the number of directors constituting the
entire Board. The By-laws provide that the number of directors shall be fixed by
the Board of Directors but in any event, shall be no less than seven (7)
(subject to decrease by a resolution adopted by the shareholders).

            At the Annual Meeting, a class of three directors will be elected
for a two-year term expiring at the Annual Meeting of Shareholders to be held in
2005. Messrs. Vincent P. Abbatecola, Robert L. Burr and Otto C. Morch are the
nominees for election to such positions, except that only the holders of the
Preferred Stock are entitled to vote for reelection of Mr. Burr. Messrs. Kevin
J. Zugibe, Harry C. Schell, Dominic J. Monetta and Robert M. Zech will not stand
for election at the Annual Meeting because their respective terms expire at the
Annual Meeting of Shareholders to be held in 2004.

            The holders of the Preferred Stock are entitled to nominate and vote
exclusively for up to two directors to the Company's Board. To date, the holders
of the Preferred Stock have nominated Robert L. Burr for election at the 2003
Annual meeting of the Shareholders and have appointed Robert M. Zech as a second
director who is part of the class of directors whose term expires at the
Company's annual meeting in 2004.

            Proxies will be voted for the nominees named below, unless authority
is withheld. Should any nominee not be available for election, proxies will be
voted for such substitute nominee as may be designated by the Board of
Directors. Each of the nominees has indicated to the Board that he will be
available.

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

            Based solely on the Company's review of the copies of such forms
received by the Company, the Company believes that during the year ended
December 31, 2002 all filing requirements applicable to its officers, directors,
and greater than 10 percent beneficial shareholders were complied with.

Employment Agreement

      Hudson has entered into a two-year employment agreement with Kevin J.
Zugibe, which expires in May 2005 and is automatically renewable for two
successive terms. Pursuant to the agreement, effective February 1, 2000, Mr.
Zugibe is receiving an annual base salary of $141,000 with such increases and
bonuses as the Board may determine. During 2002, the Board of Directors and Mr.
Zugibe agreed, at Mr. Zugibe's option, to reduce the cash compensation and
issued 45,000 additional stock options to Mr. Zugibe in satisfaction of his
annual base salary. Hudson is the beneficiary of a "key-man" insurance policy on
the life of Mr. Zugibe in the amount of $1,000,000.

Stock Option Plans

      Hudson has adopted each of an Employee Stock Option Plan (the "1994 Plan")
and the 1997 Stock Option Plan (the "1997 Plan") pursuant to which an aggregate
of 2,750,000 shares of common stock are currently reserved for issuance upon the
exercise of options designated as either (i) options intended to constitute
incentive stock options ("ISOs") under the Internal


                                      -10-


Revenue Code of 1986, as amended (the "Code"), or (ii) nonqualified options.
ISOs may be granted under either of the 1994 Plan or 1997 Plan to employees and
officers of Hudson. Non-qualified options may be granted to consultants,
directors (whether or not they are employees), employees or officers of Hudson.
Stock appreciation rights may also be issued in tandem with stock options.

      Each of the 1994 Plan and 1997 Plan is intended to qualify under Rule
16b-3 under the Securities Exchange Act of 1934, as amended (the "Exchange Act")
and is administered by the Compensation/Stock Option Committee of the Board of
Directors. The Committee, within the limitations of each of the 1994 Plan and
1997 Plan, determines the persons to whom options will be granted, the number of
shares to be covered by each option, whether the options granted are intended to
be ISOs, the duration and rate of exercise of each option, the exercise price
per share and the manner of exercise and the time, manner and form of payment
upon exercise of an option. Unless sooner terminated, the 1994 Plan will expire
on December 31, 2004 and the 1997 Plan will expire on June 11, 2007.

      ISOs granted under either of the 1994 Plan or 1997 Plan may not be granted
at a price less than the fair market value of the common stock on the date of
grant (or 110% of fair market value in the case of persons holding 10% or more
of the voting stock of Hudson). The aggregate fair market value of shares for
which ISOs granted to any employee are exercisable for the first time by such
employee during any calendar year (under all stock option plans of Hudson) may
not exceed $100,000. Non-qualified options granted under the 1994 Plan may not
be granted at a price less than 85% of the market value of the common stock on
the date of grant and new qualified options granted under the 1997 Plan may not
be granted at a price less than the par value of our common stock. Options
granted under the 1994 Plan and 1997 Plan will expire not more than ten years
from the date of grant (five years in the case of ISOs granted to persons
holding 10% or more of the voting stock of Hudson). Except as otherwise provided
by the committee with respect to non-qualified options, all options granted
under the 1994 Plan and 1997 Plan are not transferable during an optionee's
lifetime but are transferable at death by will or by the laws of descent and
distribution. In general, upon termination of employment of an optionee, all
options granted to such person which are not exercisable on the date of such
termination immediately terminate, and any options that are exercisable
terminate 90 days following termination of employment.

      As of December 31, 2002, Hudson had options outstanding to purchase
610,000 shares of common stock under the 1994 Plan. During 2000, Hudson granted
