                                 PROXY STATEMENT

                            HUDSON TECHNOLOGIES, INC.

                         ANNUAL MEETING OF SHAREHOLDERS
                         TO BE HELD ON DECEMBER 20, 2002

     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 20, 2002, 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 21, 2002.


     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.: (845) 735-6000

                       OUTSTANDING STOCK AND VOTING RIGHTS


     Only shareholders of record at the close of business on November 18, 2002
(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 5,165,020 shares of the
Company's common stock, par value $.01 per share ("Common Stock"), and 116,629
shares of the Company's Series A Convertible Preferred Stock, par value $.01 per
share ("Preferred A 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 A Stock vote together with holders of Common Stock as one class
except that only holders of the Preferred A Stock are entitled to vote on the
election of two directors to the Board appointed by them pursuant to the terms
of the Company's Certificate of Designation relating to the Preferred A Stock
(the "Series A Directors"). Mr. Robert L. Burr, whose term as director does not
expire until 2003, is a Series A Director who has previously been elected by the
holders of the Preferred A Stock. The holders of the Preferred A Stock have not
yet nominated a second Series A Director for election to the Board. Each share
of Preferred A 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 A Stock is




then convertible (which, as of the Record Date, is approximately 42.10 shares of
Common Stock for each share of Preferred A Stock, or an aggregate of 4,910,695
votes); provided, however, that each holder of Preferred A Stock has irrevocably
constituted Kevin J. Zugibe and Stephen P. Mandracchia, and each of them, as
such holder's proxy, with full power of substitution in each of them, in the
name, place and stead of such holder, to vote at all meetings of the
shareholders of the Company (other than with respect to matters requiring a
separate class vote of holders of the Preferred A Stock) that number of voting
shares of the Company of all classes held by such holder and its affiliates, in
the aggregate, as shall exceed twenty-nine percent (29%) of the votes entitled
to be cast by all shareholders of the Company. All of the outstanding Preferred
A Stock is held by Fleming US Discovery Fund III, L.P. and Fleming US Discovery
Offshore Fund III, L.P., which are affiliated with each other through their
general partner Fleming US Discovery Partners, L.P. (and its general partner
Fleming US Discovery Partners LLC) (collectively, the "Fleming Funds"), and
accordingly the Fleming Funds can vote up to an aggregate of 29% of the votes
entitled to be cast by all shareholders of the Company.

                                VOTING PROCEDURES

     At the Annual Meeting, all directors will be elected by a plurality of the
votes cast by the holders of Common Stock and Preferred A Stock, voting together
as one class, in person or represented by proxy at the Annual Meeting, provided
a quorum is present at the Annual Meeting.

     Each of the proposals (a) authorizing the Company to engage in the
convertible debt financing transaction (the "Convertible Debt Financing")
whereby the Company proposes to issue promissory notes which will be convertible
into shares of Common Stock (the "Convertible Notes") to lenders that are
expected to include certain officers of the Company, and (b) authorizing the
Company to issue promissory notes (identical in terms to the Convertible Notes)
which will be convertible into shares of Common Stock (the "Exchange Notes") in
exchange for non-convertible promissory notes (the "Bridge Notes") acquired in
the Company's bridge financing transaction (the "Bridge Financing") by lenders
that include certain officers of the Company, will require the affirmative vote
of a majority of the votes cast by the holders of Common Stock and Preferred A
Stock voting together as one class, present in person or represented by proxy at
the Annual Meeting, provided a quorum is present.

     Each of the other proposals to amend the Certificate of Incorporation
including, (x) to remove the provision in the designation of the Preferred A
Stock relating to the proxy granted by the holders of the Preferred A Stock, (y)
to remove the provision in the designation of the Preferred A Stock relating to
the floor on the conversion price (the "Conversion Price Floor") of the
Preferred A Stock, and (z) to increase the number of authorized shares of Common
Stock will require the affirmative vote of the majority of votes entitled to be
cast by the holders of Common Stock and Preferred A Stock, voting together as
one class, outstanding as of the Record Date. With respect to the proposed
amendments described in items (x) and (y) above, in addition to the vote
required for approval of each such amendment, NASDAQ may also require under its
Marketplace Rule 4350, as a result of a transaction triggering the potential for
a change of control (by virtue of the removal of the proxy) and the below market
issuance exceeding 20% of the outstanding Common Stock (by virtue of the removal
of the Conversion Price Floor), the


                                       2


affirmative vote of a majority of votes cast at the Annual Meeting by
shareholders other than the holders of the Preferred A Stock (the "NASDAQ
Votes").

     All other matters to be acted upon at the Annual Meeting will be decided by
the affirmative vote of a majority of the votes cast by the holders of the
shares of Common Stock and Preferred A Stock, voting together as one class,
present in person or represented by proxy at the Annual Meeting, provided a
quorum is present. 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 Preferred A 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.

     The holders of the Preferred A Stock and the officers of the Company
holding the proxy from the holders of the Preferred A Stock which, in the
aggregate, represent approximately 49% of the Common Stock and Preferred A
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 as well as each of the proposals set
forth in this Proxy Statement. These votes, however, will not be counted by
NASDAQ with respect to the shareholder approval required in connection with the
NASDAQ Votes.

                             SPECIAL CONSIDERATIONS

     As disclosed in greater detail in the Proposals set forth in this Proxy
Statement, at the Company's Annual Meeting, the shareholders will be called upon
to, among other things, authorize and approve the Company's engagement in a
proposed Convertible Debt Financing and a proposed exchange of Bridge Notes for
Exchange Notes (the "Note Exchange"). The Convertible Notes to be issued in the
proposed Convertible Debt Financing and Exchange Notes to be issued in the
proposed Note Exchange will be convertible into shares of Common Stock of the
Company based upon an applicable conversion rate as discussed in the Proposals
set forth below. Additionally, in each of the proposed Convertible Debt
Financing and the proposed Note Exchange the Company will issue to the
purchasers or recipients of Convertible Notes and


                                       3


Exchange Notes, as the case may be, warrants exercisable to purchase shares of
the Company's Common Stock at an applicable exercise price as discussed in the
Proposals set forth below.


     The aggregate amount of gross proceeds anticipated to be received by the
Company from the Bridge Financing and the proposed Convertible Debt Financing is
approximately $1,700,000, in which case the aggregate amount of shares of Common
Stock of the Company that would be issuable upon conversion of the Convertible
Notes and the Exchange Notes, based upon an assumed conversion rate of $1.34
(representing the average of the closing sale price of the Company's Common
Stock on the NASDAQ SmallCap Market for the five business days prior to the
Record Date) is approximately 1,268,657. In addition, the Company would incur
the obligation to issue warrants in connection with the proposed Convertible
Debt Financing and Note Exchange, to purchase an aggregate of 126,866 shares of
Common Stock, which, if exercised by the holders thereof for cash (based upon an
assumed exercise price of $1.34), would result in additional aggregate proceeds
to the Company of approximately $170,000. The shares of Common Stock that would
be issuable as a result of the conversion of the Convertible Notes and Exchange
Notes and the exercise of the warrants at the above-noted assumed conversion
rate and assumed exercise price, as the case may be, represent approximately 9%
of the aggregate of the issued and outstanding shares of Common Stock of the
Company as of the Record Date assuming the conversion of all of the outstanding
Preferred A Stock into Common Stock (and after giving effect to the conversion
of the Convertible Notes and Exchange Notes and the exercise of the warrants).


     To the extent that the Convertible Notes and Exchange Notes are converted
into shares of Common Stock and the warrants to be issued in connection with the
Convertible Debt Financing and the Note Exchange are exercised for shares of
Common Stock, the interests of the Company's existing shareholders will be
diluted. Moreover, each of the Convertible Notes, the Exchange Notes and the
warrants will provide for anti-dilution adjustment of their respective
conversion rate or exercise price, as the case may be, such that in the event of
a subsequent issuance by the Company of stock or securities exercisable for or
convertible into Common Stock (other than pursuant to shareholder approved
employee benefit plans) at a per share consideration or exercise price, as the
case may be, below the then-effective conversion rate of the Convertible Notes
and the Exchange Notes and the then-effective exercise price of the warrants,
the conversion rates or the exercise price, as the case may be, of the
Convertible Notes, Exchange Notes and warrants will be adjusted accordingly to
such lower prices. In such case the number of shares of Common Stock issuable
upon conversion of the Convertible Notes and Exchange Notes and upon exercise of
the warrants would increase proportionately, further diluting the interests of
the existing shareholders.

     Additionally, the holders of Preferred A Stock may convert their shares
into approximately 49% of all of the issued and outstanding shares of Common
Stock (giving effect to such conversion of Preferred A Stock) as of the Record
Date. The conversion price of the Preferred A Stock is subject to anti-dilution
adjustment as described above, including upon the issuance of the Convertible
Notes, the Exchange Notes and the warrants in connection with the proposed
Convertible Debt Financing and the Note Exchange. Although, as discussed in
Proposal IV below, the holders of Preferred A Stock have agreed to waive the
anti-dilution adjustment to the conversion price of the Preferred A Stock upon
the issuance of the Convertible


                                       4


Notes, the Exchange Notes and the warrants, this waiver does not extend to any
subsequent issuances that may affect the conversion price of the Preferred A
Stock.

     As a result of the foregoing anti-dilution features, the holders of the
Convertible Notes, Exchange Notes and warrants will have, and the holders of the
Preferred A Stock currently have (subject to a conversion price floor discussed
in Proposal IV below) protection of their prospective percentage interest in the
Company upon the occurrence of certain subsequent diluting events. Existing
shareholders of the Company do not have such protection and, therefore, would
experience dilution to their respective percentage interest in the Company upon
a subsequent diluting event. Moreover, the potential for the issuance of
additional shares of Common Stock resulting from such anti-dilution protection
coupled with the conversion and/or exchange feature of the Convertible Notes,
Exchange Notes, Preferred A Stock and warrants, as the case may be, could create
downward pressure on the market price of the Company's Common Stock, increasing
the possibility that a subsequent issuance of securities by the Company would be
for consideration below the then-effective conversion rates and/or exercise
prices of the Convertible Notes, Exchange Notes, Preferred A Stock and warrants,
in which case such issuance would trigger such anti-dilution adjustment. To the
extent that the Convertible Notes, Exchange Notes and Preferred A Stock are
converted, and the warrants are exercised, the increase in the shares of Common
Stock issued resulting from such anti-dilution adjustment would, in addition to
the dilutive effect to the percentage interest of the existing shareholders,
negatively impact the per share book value of the Company, and could impair the
Company's ability to raise additional capital through the sale of equity
securities.

                              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 four directors will be elected for a
two-year term expiring at the Annual Meeting of Shareholders to be held in 2004.
Messrs. Kevin J. Zugibe, Dominic J. Monetta, Harry C. Schell and Robert M. Zech
are the nominees for election to such positions. Messrs. Vincent P. Abbatecola,
Robert L. Burr and Otto C. Morch will not stand for election at the Annual
Meeting because their respective terms expire at the Annual Meeting of
Shareholders to be held in 2003.

     The holders of the Preferred A 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 A Stock have nominated and elected one director who is part of
the class of directors whose term expires at the Company's annual meeting in
2003 and have not yet nominated a second director for election to the Board.

     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


                                       5

Stock Option Plan

1994 Stock Option Plan

     The Company has adopted an Employee Stock Option Plan (the "Plan")
effective October 31, 1994 pursuant to which 725,000 shares of Common Stock are
currently reserved for issuance upon the exercise of options designated as
either (i) options intended to constitute incentive stock options ("ISOs") under
the Internal Revenue Code of 1986, as amended (the "Code"), or (ii) nonqualified
options. ISOs may be granted under the Plan to employees and officers of the
Company. Non-qualified options may be granted to consultants, directors (whether
or not they are employees), employees or officers of the Company. Stock
appreciation rights may also be issued in tandem with stock options.

     The Plan is intended to qualify under Rule 16b-3 under the Exchange Act and
is administered by a committee of the Board of Directors, which currently
consists of Messrs. Abbatecola, Burr, Morch and Schell. The committee, within
the limitations of the 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 Plan will expire on December 31, 2004.

     ISOs granted under the Plan may not be granted at a price less than the
fair market value of the Common Stock on the date of grant (or 110% of fair
market value in the case of persons holding 10% or more of the voting stock of
the Company). The aggregate fair market value of shares for which ISOs granted
to any employee are exercisable for the first time by such employee during any
calendar year (under all stock option plans of the Company) may not exceed
$100,000. Non-qualified options granted under the Plan may not be granted at a
price less than 85% of the market value of the Common Stock on the date of
grant. Options granted under the Plan will expire not more than ten years from
the date of grant (five years in the case of ISOs granted to persons holding 10%
or more of the voting stock of the Company). All options granted under the 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
by 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, 2001, options to purchase 618,906 shares of Common Stock
were issued under the Plan. During 2000, the Company granted options to purchase
40,000 shares to each of Kevin J. Zugibe, Stephen P. Mandracchia and Thomas P.
Zugibe. Such options


                                       13

purchase shares to Kevin J. Zugibe, 50,000 shares; Brian F. Coleman, 20,000
shares; Stephen P. Mandracchia, 15,000 shares; and Thomas P. Zugibe, 20,000
shares, all of which are exercisable at $2.55 per share. Such options vest
quarterly in equal amounts over three years, commencing with the first quarter
of 2002. In addition, during 2001, the Company also granted options to purchase
15,000 shares to Kevin J. Zugibe exercisable at $2.55 per share, all of which

December 13, 2002 and 1,570 on December 13, 2003. In addition, during 2001, the
Company also granted options to certain employees to purchase 20,000 shares
exercisable at $2.55 per share. Such options vest quarterly in equal amounts
over three years, commencing with the first quarter of 2002.

1997 Stock Option Plan

     The Company has adopted the 1997 Stock Option Plan (the "1997 Plan"),
pursuant to which 2,000,000 shares of Common Stock are currently reserved for
issuance upon the exercise of options designated as either (i) options intended
to constitute ISOs under the Code, or (ii) nonqualified options. ISOs may be
granted under the 1997 Plan to employees and officers of the Company.
Non-qualified options may be granted to consultants, directors (whether or not
they are employees), employees or officers of the Company. Stock appreciation
rights may also be issued in tandem with stock options.

     The 1997 Plan is intended to qualify under Rule 16b-3 under the Exchange
Act and is administered by a committee of the Board of Directors, which
currently consists of Messrs. Abbatecola, Burr, Morch and Schell. The committee,
within the limitations of the 1997 Plan, determines the persons to whom options
will be granted, the number of shares to be covered by each option, whether the
options granted are intended to be ISOs, the duration and rate of exercise of
each option, the exercise price per share and the manner of exercise and the
time, manner and form of payment upon exercise of an option. Unless sooner
terminated, the 1997 Plan will expire on June 11, 2007.

     ISOs granted under the 1997 Plan may not be granted at a price less than
the fair market value of the Common Stock on the date of grant (or 110% of fair
market value in the case of persons holding 10% or more of the voting stock of
the Company). The aggregate fair market value of shares for which ISOs granted
to any employee are exercisable for the first time by such employee during any
calendar year (under all stock option plans of the Company) may not exceed
$100,000. Non-qualified options granted under the 1997 Plan may not be granted
at a price less than the par value of the Common Stock on the date of grant.
Options granted under the 1997 Plan will expire not more than ten years from the
date of grant (five years in the case of ISOs granted to persons holding 10% or
more of the voting stock of the Company). All options granted under the 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.

                                   PROPOSAL I

            TO AUTHORIZE THE COMPANY TO ENGAGE IN A CONVERTIBLE DEBT
          FINANCING WITH LENDERS WHICH ARE EXPECTED TO INCLUDE CERTAIN
                            OFFICERS OF THE COMPANY

     The Board of Directors of the Company has adopted a resolution, and submits
to shareholders for approval, a proposal authorizing the Company to enter into a
Convertible Debt Financing with several lenders which are expected to include
certain officers of the Company as described more fully below.

Description of the Convertible Debt Financing

     The Company intends to raise approximately $850,000 in the Convertible Debt
Financing. The Company, however, may complete the Convertible Debt Financing if
at least $450,000 is received and may increase the Convertible Debt Financing to
up to $1.7 million. The Company will issue to the lenders in the Convertible
Debt Financing, Convertible Notes each having a term of two years from issuance,
bearing interest at the annual rate of 10%, which interest will be payable
quarterly in arrears. At the time of issuance of the Convertible Notes, the
lenders will have a one-time option to defer quarterly interest payments until
the maturity date of the Convertible Notes, in which case the deferred interest
will accrue interest (the "Additional Interest") at the annual rate of 10%. The
holders of Convertible Notes will also have the right to convert such
Convertible Notes into shares of the Company's Common Stock, as described more
fully below. Subject to the prior consent of The CIT Group/Credit Finance, Inc.
("CIT Group"), an existing creditor of the Company with a first priority lien
and security interest in substantially all of the assets of the Company, the
Convertible Notes will be secured by all of the assets of the Company. The
security interest evidenced by the Convertible Notes will rank pari passu with
the security interest to be evidenced by the Exchange Notes (discussed in
Proposal II below), but will be subordinate to the first priority lien and
security interest held by CIT Group as well as liens currently held by and
subsequently obtained by certain third-party purchase money lenders on specific
assets of the Company. The Company will have the right to prepay, in cash or in
shares of Common Stock at the Conversion Rate (defined below) then in effect,
all or a portion of the principal amount of the Convertible Notes, together with
accrued and unpaid interest thereon if any (together with Additional Interest),
at any time during their term and prior to maturity upon twenty (20) days prior
written notice to the lender or lenders subject to such prepayment.

     The Company's payment, in cash, of interest and or principal under the
Convertible Notes will be conditioned upon (a) the prior written consent of CIT
Group or its successor to or assignee of the loan and security agreement (the
"Loan Agreement") between CIT Group and Hudson Technologies Company, a
wholly-owned subsidiary of the Company ("Hudson"), and (b) as of the time of a
proposed cash payment of interest and/or principal by the Company (i) no event
of default under the Loan Agreement shall have occurred or be in existence,
which default has not been cured or waived, and (ii) the Company's cash and/or
cash equivalents on hand and/or Hudson's borrowing availability under the Loan
Agreement shall equal, in the aggregate, not less than $850,000. None of the
foregoing conditions will apply, however, in the event of the conversion of the
Convertible Notes into shares of Common Stock


                                       20


or the application of the debt evidenced by such Convertible Notes to acquire
shares of Common Stock of the Company.

     Upon, but not prior to, the first anniversary of the Convertible Debt
Financing, the holders of Convertible Notes will have the option to convert all
or a portion of the principal amount of the Notes then outstanding and/or
accrued and unpaid interest thereon if any (together with Additional Interest),
into shares of the Company's Common Stock. The initial conversion rate of the
Convertible Notes will be equal to the average of the closing price of the
Company's Common Stock as reported on the NASDAQ SmallCap Market for the five
business days prior to the closing date of the Convertible Debt Financing (the
"Conversion Rate"). The Conversion Rate will be subject to subsequent adjustment
as a result of the issuance by the Company of Common Stock or warrants, rights
to purchase (other than options granted by the Company under shareholder
approved stock option plans and shares issuable upon exercise thereof or upon
exercise of options or warrants or conversion of notes of the Company
outstanding immediately prior to the closing of the Convertible Debt Financing)
or other exercisable, exchangeable or convertible debt or equity securities
(each an "Additional Issuance") at a consideration per share which is less than
the Conversion Rate then in effect. In such a case the Conversion Rate will be
adjusted to equal the consideration per share received by the Company for the
securities issued in the Additional Issuance. In addition, the Conversion Rate
will be subject to an appropriate adjustment in the event of the following: (a)
upon a subdivision, combination or reclassification by the Company of its Common
Stock; (b) upon the payment of dividends in shares of common stock, or (c) upon
the consolidation or merger of the Company with or into another corporation
whereby the Company is the surviving entity, or upon the sale or distribution of
substantially all of the Company's assets.

     At any time prior to the first anniversary of the Convertible Debt
Financing, all of the outstanding principal and accrued interest, if any
(together with any accrued but unpaid Additional Interest) of the Convertible
Notes shall either (i) be applied to the purchase of securities to be offered by
the Company at the public offering purchase price, in any public offering by the
Company of equity securities which, when aggregating the outstanding principal
and accrued interest of the Convertible Notes together with the outstanding
principal and accrued interest of the Exchange Notes and all additional proceeds
from new investors, equals not less than $2,000,000 (the "Equity Offering"), or
(ii) in the event of such Equity Offering, be converted into shares of Common
Stock at the then-effective Conversion Rate. The holders of the Convertible
Notes will have the right to determine, to the extent that securities are
available for purchase in the Equity Offering, whether to apply the outstanding
principal and interest, if any, of a Convertible Note to the purchase of the
securities in the Equity Offering or to convert the same into shares of Common
Stock at the then-effective Conversion Rate; provided, however, that in the
event that all or a portion of outstanding principal and interest, if any, of a
Convertible Note exceeds the number of equity securities available in the Equity
Offering, the balance of the Convertible Note not applied to the purchase of
equity securities will be converted into Common Stock at the then-effective
Conversion Rate.

     In addition, as consideration for their participation in the Convertible
Debt Financing, the Company will issue to the holders of the Convertible Notes
on the earlier of (a) the first anniversary of the closing date of the
Convertible Debt Financing, or (b) the consummation by the Company of an Equity
Offering, Common Stock purchase warrants (the


                                       21


"Convertible Note Warrants") to purchase an aggregate number of shares of Common
Stock equal to 10% of the number of shares of Common Stock into which the
Convertible Notes are convertible at the date of the closing of the Convertible
Debt Financing. Each Convertible Note Warrant will be exercisable to purchase
one share of Common Stock for a period of five years from issuance at an
exercise price (the "Exercise Price") equal to 110% of the lesser of (i) the
Conversion Rate of the Convertible Notes as of the closing date of the
Convertible Debt Financing, or (ii) the Conversion Rate of the Convertible Notes
on the date of issuance of the Warrants. The Exercise Price of the Convertible
Note Warrants will be subject to anti-dilution adjustment on terms substantially
similar to the anti-dilution adjustment of the Conversion Rate of the
Convertible Notes.

Purpose of Convertible Debt Financing

     As a result of current market conditions, revenues from the Company's
operations are not currently sufficient to support its operating activities and,
as such, the Company is in need of additional financing prior to the end of 2002
in order to support its continuing operations. Management has investigated
potential sources of debt or equity financings and concluded that either such
financings are not currently available to the Company, or with respect to those
financings that are available, the proposed terms of such financings are not
commercially reasonable to the Company. As a result, the Company has determined
to pursue the Convertible Debt Financing with several lenders which are expected
to include certain of the Company's officers including Messrs. Brian F. Coleman,
the Company's President and Chief Operating Officer and Stephen P. Mandracchia,
the Company's Vice President of Operations. In addition, certain relatives of
the officers and directors of the Company as well as the Fleming Funds,
principal shareholders of the Company, may participate in the Convertible Debt
Financing.

Consent of Holders of Preferred A Stock

     The Fleming Funds hold an aggregate of 116,629 shares of Preferred A Stock,
constituting all of the Company's issued and outstanding Preferred A Stock as of
the Record Date. The Preferred A Stock is convertible into an aggregate of
4,910,695 shares of the Company's Common Stock or approximately 49% of all of
the issued and outstanding Common Stock of the Company after conversion of the
Preferred A Stock (assuming no other conversion or exchange of outstanding
securities of the Company) as of the Record Date, at the current conversion
price, as set forth in the designation of the Preferred A Stock, of $2.375 (the
"Conversion Price"). Because the Preferred A Stock votes together with the
Common Stock of the Company as one class (except for the election of two
directors, for which only the Preferred A Stock have the right to vote), the
Fleming Funds would otherwise have the ability to provide for approximately 49%
of the vote on matters brought before the shareholders of the Company, thereby
enabling the Fleming Funds to significantly influence the ultimate shareholder
determinations on matters presented for a vote.

     Pursuant to stock purchase agreements, as amended, in accordance with which
the Fleming Funds acquired the Preferred A Stock (the "Fleming Purchase
Agreements"), the Company is restricted, without the prior written consent of
the Fleming Funds, from issuing or selling securities, including securities such
as the Convertible Notes and Convertible Note


                                       22


Warrants to be included in the Convertible Debt Financing (as well as the
Exchange Notes and the Exchange Note Warrants (defined below) to be issued in
the Note Exchange as described in Proposal II below), which are convertible or
exchangeable into shares of Common Stock for a consideration per share that is
less than the Conversion Price of the Preferred A Stock then in effect
immediately prior to such proposed issuance or sale of securities. Based on the
market price of the Company's Common Stock as of the Record Date, the Conversion
Rate of the Convertible Notes to be issued in the Bridge Financing would be
approximately $1.55 per share of Common Stock, which is below the current
Conversion Price of the Preferred A Stock ($2.375). Consequently, the Company
would not be able to engage in the Convertible Debt Financing without the prior
written consent of the Fleming Funds.

     The Fleming Funds have agreed to consent to the Convertible Debt Financing.
As consideration for, among other things, their consent to the Convertible Debt
Financing and the Note Exchange as discussed below, the Company, at the request
of the Fleming Funds, has agreed to amend: (i) Section 4(a) of Paragraph (5) of
the Company's Certificate of Incorporation to remove the provision for a Proxy
(defined below in Proposal III) granted by the holders of Preferred A Stock in
favor of the Hudson Officers (defined below in Proposal III); and (ii) Section
5(d)(ii) of Paragraph 5 of the Company's Certificate of Incorporation to remove
the provision relating to a Conversion Price Floor with respect to the
conversion price of the Preferred A Stock. The removal of the Proxy would allow
for the Fleming Funds to vote all of the Common Stock into which the Preferred A
Stock is then convertible, subject to the Disparate Voting Limitation (defined
below in Proposal IV), at all meetings of shareholders of the Company and the
removal of the Conversion Price Floor would allow for the conversion price of
the Preferred A Stock to be adjusted to equal the consideration per share at any
price received by the Company in an Additional Issuance, and a corresponding
increase in the number of shares of Common Stock into which the Preferred A
Stock is convertible.

Necessity for Shareholder Approval

     Because the Company's Common Stock is listed on the NASDAQ SmallCap Market,
the Company is subject to NASDAQ Marketplace Rules. NASDAQ Marketplace Rule
4350(i)(1)(D)(ii) requires that a company listed on NASDAQ obtain shareholder
approval in connection with a transaction (other than a public offering)
involving the potential issuance of common stock (or securities convertible into
or exercisable for common stock) equal to 20% or more of its common stock or 20%
or more of its voting power outstanding before the issuance for less than the
greater of book or market value of the stock as of the date of the transaction.
To the extent that a NASDAQ listed company does not obtain shareholder approval
to such an arrangement and otherwise proceeds with such an arrangement, that
company may be subject to the delisting of its securities from NASDAQ.

     The Convertible Notes to be issued by the Company in the proposed
Convertible Debt Financing will be convertible into shares of Common Stock,
pursuant to the terms of the Convertible Notes, at the Conversion Rate which
will be subject to adjustment in certain circumstances, including in the event
of an Additional Issuance by the Company at a consideration per share below the
then-effective Conversion Rate. The Convertible Note Warrants to be issued by
the Company as a result of the Convertible Debt Financing will, when issued, be
exercisable for shares of the Company's Common Stock at any time from their


                                       23



issuance until their termination at the then applicable Exercise Price which
will be subject to adjustment on terms substantially similar to the adjustment
of the Conversion Rate of the Convertible Notes. Any Additional Issuance at a
consideration per share below the then-effective Conversion Rate will act to
immediately reduce the Conversion Rate of the Notes then in effect to equal the
amount of per share consideration received by the Company in connection with
such Additional Issuance. Since the Conversion Rate of the Convertible Notes and
the applicable Exercise Price of the Convertible Note Warrants will initially be
set at the market price of the Company's Common Stock at the closing of the
Convertible Debt Financing, any Additional Issuance for a per share
consideration below the Conversion Rate will, as a result of the adjustment
provision of the Conversion Rate, reduce the amount of the Conversion Rate to
below market value and, consequently, reduce the applicable Exercise Price of
the Convertible Note Warrants to below market value. In addition, as the
Conversion Rate is adjusted downward the number of shares of Common Stock
issuable upon conversion of the Convertible Notes increases such that, the
potential exists that the Convertible Notes and the Convertible Note Warrants
would be convertible and exercisable, as the case may be, at a rate below the
market price of the Common Stock on the closing of the Convertible Debt
Financing for an aggregate number of shares of Common Stock equal to 20% or more
of the Company's outstanding Common Stock prior to the Convertible Debt
Financing. The Company, therefore has submitted this Proposal for shareholder
approval in accordance with Marketplace Rule 4350(i)(1)(D)(ii).


     In addition, the Company is subject to Marketplace Rule 4350(i)(1)(A) which
requires that a company listed on NASDAQ obtain shareholder approval of an
arrangement made pursuant to which stock in excess of the lesser of (a) 1% of
the number of shares of such company's currently outstanding common stock, (b)
1% of the outstanding voting power of the company, or (c) 25,000 shares will be
acquired by officers or directors (other than with respect to warrants or rights
generally issued to shareholders of the Company and broad based plans). To the
extent that a NASDAQ listed company does not obtain shareholder approval to such
an arrangement and otherwise proceeds with such an arrangement, that company may
be subject to the delisting of its securities from NASDAQ.


     Based upon discussions among the parties, the Fleming Funds have indicated
their intention to purchase up to an aggregate of $750,000 principal amount of
the Convertible Notes, less any principal amount of Bridge Notes that the
Fleming Funds may acquire in the Bridge Financing. However, despite these
discussions, the Fleming Funds are not obligated to purchase any amount of the
Bridge Notes or the Convertible Notes. Additionally, several of the Company's
officers noted above are expected to purchase up to an aggregate of $100,000
principal amount of Convertible Notes in the Convertible Debt Financing.
Assuming a Conversion Rate of $1.34 (based upon the average of the closing price
of the Company's Common Stock for the five business days prior to the Record
Date, such officers would be able to convert the principal amount of their
Convertible Notes into an aggregate of approximately 74,627 shares of the
Company's Common Stock, exceeding the 25,000 share maximum issuance permitted by
Marketplace Rule 4350. Such officers and directors would also be eligible to
exercise the Convertible Note Warrants, to be issued as discussed above, into
shares of the Company's Common Stock. Although it is the Company's understanding
that such Marketplace Rule would otherwise permit, without prior shareholder
approval, the private sale of securities such as the proposed Convertible Debt
Financing, wherein the securities are deemed to be offered at or above fair
market value and the officers or directors are participating on the same



                                       24


terms as other potential investors, the provision in the Convertible Notes and
the Convertible Note Warrants for adjustment of the Conversion Rate and
applicable Exercise Price in the event of an Additional Issuance at a
consideration per share below the Conversion Rate and applicable Exercise Price
then in effect triggers the application of Marketplace Rule 4350(i)(1)(A) where
stock may be issued to officers and directors. Consequently, the Company has
submitted this Proposal for shareholder approval.

Required Vote

     Approval by shareholders of this Proposal I requires the affirmative vote
of a majority of the votes cast by the holders of the shares of Common Stock and
Preferred A Stock, voting together as one class, present in person or
represented by proxy at the Annual Meeting, provided a quorum is present.

Recommendation

     The Board of Directors believes that it is in the best interests of the
Company that the shareholders authorize the Company to engage in the Convertible
Debt Financing.

     THE BOARD OF DIRECTORS RECOMMENDS THAT SHAREHOLDERS VOTE FOR PROPOSAL I TO
AUTHORIZE THE COMPANY TO ENGAGE IN A CONVERTIBLE DEBT FINANCING WITH LENDERS
WHICH IS EXPECTED TO INCLUDE CERTAIN OFFICERS OF THE COMPANY.


                                       25


                                   PROPOSAL II

         TO AUTHORIZE THE COMPANY TO ISSUE EXCHANGE NOTES, WHICH WILL BE
        IDENTICAL IN TERMS TO THE CONVERTIBLE NOTES TO BE ISSUED BY THE
        COMPANY IN THE PROPOSED CONVERTIBLE DEBT FINANCING, IN EXCHANGE
          FOR BRIDGE NOTES ACQUIRED BY LENDERS, WHICH INCLUDE CERTAIN
                            OFFICERS OF THE COMPANY

     The Board of Directors has adopted a resolution declaring the advisability
of, and submits to the shareholders for approval, a proposal authorizing the
Company to issue Exchange Notes (which will be identical in terms to the
Convertible Notes to be issued by the Company in the proposed Convertible Debt
Financing) in exchange for Bridge Notes acquired in the Company's Bridge
Financing by lenders which include certain officers the Company as described
more fully below.

Purpose of the Bridge Financing

     As noted above in Proposal I, the Company is in need of additional
financing in order to support its operating activities. The proposed Convertible
Debt Financing, if approved by the shareholders at the Annual Meeting, is
expected to provide the Company with the financing required to satisfy its
operating costs in the near term. However, in order to maintain the listing of
its Common Stock on NASDAQ, the Company must comply with the NASDAQ Marketplace
Rules that require the Company to obtain shareholder approval prior to engaging
in and consummating the proposed Convertible Debt Financing. As a result, the
Company would not be able to secure and utilize proceeds from such proposed
Convertible Debt Financing until, at the earliest, the completion of the Annual
Meeting (provided shareholder approval of such Convertible Debt Financing is
obtained). Due to these time constraints, the Company is engaged in the Bridge
Financing described in greater detail below in order to secure funds on an
immediate basis, thereby enabling the Company to satisfy its existing operating
expenses pending the Annual Meeting and (subject to shareholder approval)
subsequent Convertible Debt Financing.

Description of the Bridge Financing

     The Company intends to raise approximately $850,000 in the Bridge
Financing. The Company will issue to the lenders unsecured Bridge Notes, each
having a term of one (1) year from issuance, bearing interest at the annual rate
of 12%, which interest will be payable quarterly in arrears. At the time of
issuance of the Bridge Notes, the lenders have the one-time option to defer
quarterly interest payment until the maturity date of the Bridge Notes, in which
case the deferred interest will accrue Additional Interest at the annual rate of
12%. The Company shall have the right to prepay, in cash only, all or a portion
of any accrued and unpaid interest thereon, if any (together with all Additional
Interest), at any time during their term and prior to maturity upon twenty (20)
days prior written notice to the lender or lenders subject to such prepayment.

     The Company's payment, in cash, of interest and/or principal under the
Bridge Notes and, when issued upon shareholder approval in the Note Exchange as
described below, the


                                       26


Exchange Notes, will be conditioned upon (a) the prior written consent of CIT
Group or its successor to or assignee of the Loan Agreement, and (b) as of the
time of a proposed cash payment of interest and/or principal by the Company (i)
no event of default under the Loan Agreement shall have occurred or be in
existence, which default has not been cured or waived, and (ii) the Company's
cash and/or cash equivalents on hand and/or Hudson's borrowing availability
under the Loan Agreement shall equal, in the aggregate, not less than $850,000.
None of the foregoing conditions will apply, however, in the event of the
conversion of the Exchange Notes into shares of Common Stock or the application
of the debt evidenced by such Exchange Notes to acquire shares of Common Stock
of the Company.

Exchange of Bridge Notes For Convertible Notes

     The Bridge Notes being issued in the Bridge Financing are not convertible
into equity securities of the Company and, consequently, the Company does not
require, and is not seeking, shareholder approval with respect to the Bridge
Financing and issuance of the Bridge Notes to the purchasers thereof. The Bridge
Financing, however, enables the Company to secure and utilize the proceeds
thereof on an immediate basis and to satisfy continued operating costs and
expenses pending the Annual Meeting and (subject to shareholder approval) the
consummation by the Company of the proposed Convertible Debt Financing. As noted
in Proposal I, the Company has investigated alternate sources of potential
financing and has concluded from such investigation that either such financings
are not available to the Company, or those financings that are available are not
commercially reasonable to the Company.

     The proposed Note Exchange, whereby the Company will issue the Exchange
Notes (which will be identical in terms to the Convertible Notes to be issued in
the proposed Convertible Debt Financing) in exchange for the outstanding Bridge
Notes to be issued in the Company's pending Bridge Financing, will be effective
upon the Company obtaining the requisite shareholder approval of this Proposal
II at the Annual Meeting. To effectuate such exchange, the holder of a Bridge
Note will be required to submit his Bridge Note to the Company for cancellation
in exchange for an Exchange Note in a principal amount equal to the aggregate of
the outstanding principal amount of the Bridge Note submitted for cancellation
together with interest, if any (and Additional Interest), unpaid and accrued on
such Bridge Note as of the effective date of the Note Exchange.

     As with the Convertible Notes, the Exchange Notes will be convertible at
the option of the holders thereof upon, but not prior to, the first anniversary
of the Note Exchange. Similarly, at any time prior to the first anniversary of
the Note Exchange all of the outstanding principal and accrued interest, if any
(together with Additional Interest) of the Exchange Notes shall either (i) be
applied to the purchase of securities to be offered by the Company at the public
offering purchase price, in any Equity Offering the proceeds of which equal not
less than $2,000,000, or (ii) in the event of such Equity Offering, be converted
into shares of Common Stock at the then-effective Conversion Rate. The holders
of the Exchange Notes will have the right to determine, to the extent that
securities are available for purchase in the Equity Offering, whether to apply
the outstanding principal and interest, if any, of an Exchange Note to the
purchase of the securities in the Equity Offering or to convert the same into
shares of Common Stock at the then-effective Conversion Rate; provided, however,
that in the event that all or a portion of outstanding principal and interest,
if any, of an Exchange Note exceeds the number of


                                       27


equity securities available in the Equity Offering, the balance of the Exchange
Note not applied to the purchase of equity securities will be converted into
Common Stock at the then-effective Conversion Rate.

     In connection with the Note Exchange and as consideration for their
participation in the Bridge Financing, the Company will issue to the holders of
the Exchange Notes on the earlier of (a) the first anniversary of the Note
Exchange, or (b) the consummation by the Company of an Equity Offering, Common
Stock purchase warrants (similar in all respects to the Convertible Note
Warrants to be issued by the Company in the Convertible Debt Financing) (the
"Exchange Note Warrants") exercisable to purchase an aggregate number of shares
of Common Stock equal to 10% of the number of shares of Common Stock into which
the Exchange Notes are convertible at the date of the Note Exchange.

     As the Note Exchange will be effective upon the receipt by the Company of
the requisite shareholder approval for this Proposal II at the Annual Meeting,
to the extent that, at the time of such exchange, the conversion rate of the
Exchange Notes would be less than the Conversion Price of the Preferred A Stock
then in effect, the Note Exchange would otherwise be restricted by the terms of
the Fleming Purchase Agreements discussed above in Proposal I. As with the
Convertible Debt Financing, however, the Fleming Funds have agreed to consent to
the Bridge Financing and the proposed Note Exchange.

     The proposed Note Exchange discussed herein is not contingent upon
shareholder approval of the proposed Convertible Debt Financing presented in
Proposal I, and to the extent that the Company is unable to obtain shareholder
approval for the proposed Convertible Debt Financing but is able to obtain
shareholder approval for the Note Exchange presented in this Proposal II, the
Company intends to proceed with such Note Exchange. The Company believes that
the exchange of the Bridge Notes for Exchange Notes would benefit the Company in
that (i) it would reduce the effective annual interest rate on such debt to 10%
and (ii) due to the conversion feature of the Exchange Notes and the Company's
ability to prepay principal and/or interest of the Exchange Notes in cash or in
shares of Common Stock, it would reduce the payment burden associated with short
term debt and provide the Company with greater flexibility with respect to the
application of its cash resources.

Necessity For Shareholder Approval

     As noted above, the Company's engagement in the Bridge Financing and the
issuance of the Bridge Notes does not require shareholder approval. The proposal
for the Note Exchange, however, requires shareholder approval for the same
reasons described in the section entitled "Necessity for Shareholder Approval"
set forth in Proposal I above. The Exchange Notes would be otherwise identical
to the Convertible Notes to be issued in the proposed Convertible Debt
Financing, particularly with respect to the Conversion Rate of the Convertible
Notes. Similarly, the Exchange Note Warrants would be otherwise identical to the
Convertible Note Warrants, particularly with respect to the applicable exercise
price of the Convertible Note Warrants. Consequently, in the event of a
subsequent Additional Issuance for a consideration per share below the
then-effective conversion rate of the Exchange Notes, the adjustment provision
of the conversion rate of the Exchange Notes, would reduce the amount of the
conversion rate of the Exchange Notes to below market value and, consequently,
reduce the


                                       28


applicable Exercise Price of the Exchange Note Warrants to below market value.
In addition, as the conversion rate of the Exchange Notes is adjusted downward
the number of shares of Common Stock issuable upon conversion of the Exchange
Notes increases such that, the potential exists that the Exchange Notes and the
Exchange Note Warrants would be convertible and exercisable, as the case may be,
at a rate below the market price of the Common Stock on the Note Exchange for an
aggregate number of shares of Common Stock equal to 20% or more of the Company's
outstanding Common Stock prior to the Note Exchange. Therefore, the proposal to
authorize the Company to issue the Exchange Notes in exchange for the
outstanding Bridge Notes could be deemed subject to NASDAQ Marketplace Rule
4350(i)(1)(D)(ii) requiring shareholder approval for transactions (other than a
public offering) involving the issuance or potential issuance of common stock or
securities convertible into or exercisable for common stock equal to 20% or more
of the voting power outstanding before such issuance for less than the greater
of book or market value of the stock.

     Certain of the lenders in the Bridge Financing include officers of the
Company, including Messrs. Brian F. Coleman and Steven P. Mandracchia. In
addition, certain relatives of officers and directors of the Company as well as
the Fleming Funds, principal shareholders of the Company, have participated in
the Bridge Financing. As certain of the lenders in the Bridge Financing are
officers of the Company, the proposal to issue Exchange Notes for the
outstanding Bridge Notes to such officers could be deemed to be subject to
NASDAQ Marketplace Rule 4350(i)(1)(A) which requires shareholder approval for an
arrangement made pursuant to which "stock in excess of the lesser of (a) 1% of
the number of currently outstanding shares of common stock, (b) 1% of the
outstanding voting power or (c) 25,000 shares will be acquired by officers or
directors (other than with respect to broad based employee benefit plans). Upon
receipt of the Exchange Notes in exchange for the Bridge Notes, the officers
participating in such Note Exchange would be eligible to convert the Exchange
Notes into the Company's Common Stock. Such officers would also be eligible to
exercise the Exchange Note Warrants to be issued in connection with the Note
Exchange into shares of the Company's Common Stock. As discussed above with
respect to the proposed Convertible Debt Financing, although it is the Company's
understanding that the NASDAQ Marketplace Rule would otherwise permit, without
prior shareholder approval, the proposed Note Exchange wherein the securities
are deemed to be issued at or above fair market value and the officers are
participating on the same terms as other investors, the provision in the
Exchange Notes and the Exchange Note Warrants providing for adjustment of the
conversion rate and applicable exercise price in the event of an Additional
Issuance at a consideration per share below the conversion rate and applicable
exercise price then in effect trigger the application of NASDAQ Marketplace Rule
4350(i)(1)(A) where stock may be issued to officers. Consequently, the Company
has submitted this Proposal for shareholder approval.

Required Vote

     Approval by shareholders of this Proposal II requires the affirmative vote
of a majority of the votes cast by the holders of the shares of Common Stock and
Preferred A Stock, voting together as one class, present in person or
represented by proxy at the Annual Meeting, provided a quorum is present.


                                       29


Recommendation

     The Board of Directors believes that it is in the best interest of the
Company that the shareholders authorize the Company to issue the Exchange Notes
to the holders of the Bridge Notes in exchange for and upon cancellation of such
Bridge Notes.

     THE BOARD OF DIRECTORS RECOMMENDS THAT SHAREHOLDERS VOTE FOR PROPOSAL II TO
AUTHORIZE THE COMPANY TO ISSUE THE EXCHANGE NOTES IN EXCHANGE FOR THE BRIDGE
NOTES ACQUIRED IN THE COMPANY'S BRIDGE FINANCING BY LENDERS WHICH INCLUDE
CERTAIN OFFICERS OF THE COMPANY


                                       30


                                  PROPOSAL III

               TO AMEND THE CERTIFICATE OF INCORPORATION TO REMOVE
               THE PROVISION FROM THE DESIGNATION OF THE SERIES A
                  PREFERRED STOCK RELATING TO THE PROXY GRANTED
                BY THE HOLDERS OF THE SERIES A PREFERRED STOCK IN
                    FAVOR OF CERTAIN OFFICERS OF THE COMPANY

     The Board of Directors of the Company has adopted a resolution declaring
the advisability of, and submits to the shareholders for approval, a proposal to
authorize an amendment to Section 4(a) of Paragraph 5 of the Certificate of
Incorporation of the Company, substantially in the form of Exhibit A attached
hereto, to remove the provision in the designation of the Preferred A Stock,
relating to the proxy granted by holders of the Preferred A Stock which
irrevocably constitutes Kevin J. Zugibe, the Company's Chairman and Chief
Executive Officer, and Stephen P. Mandracchia, the Company's Vice President of
Operations and Secretary (the "Hudson Officers"), and each of them, with full
power to vote in the place and stead of the holders of the Preferred A Stock at
all shareholder meetings, that number of the Company's voting shares of all
classes held by the holders of the Preferred A Stock as shall exceed twenty-nine
(29%) percent of the votes entitled to be cast by all shareholders of the
Company (the "Proxy").

Reason for the Proposed Amendment

     As discussed herein above, the Company is in need of additional financing
such as that contemplated in the Bridge Financing and the proposed Convertible
Debt Financing in order to be able to support its operating activities prior to
the end of 2002. Due, however, to the restrictions set forth in the Fleming
Purchase Agreements with respect to the issuances or sales of convertible
securities for per share consideration below the then-effective Conversion Price
of the Preferred A Stock, based upon the Conversion Rate of the Convertible
Notes to be offered in the Convertible Debt Financing and the conversion rate of
the Exchange Notes to be issued in the Note Exchange, in each case calculated as
of the Company's market price on the Record Date, the Company would not be able
to proceed with the Convertible Debt Financing or the Note Exchange without the
prior written consent of the Fleming Funds. The Fleming Funds, however, have
agreed to consent to the Convertible Debt Financing and the Note Exchange. As
consideration for, among other things, the consent of the Fleming Funds to the
Convertible Debt Financing and the Note Exchange, the Company, at the request of
the Fleming Funds, has agreed to amend its Certificate of Incorporation to
remove the Proxy granted by the holders of the Preferred A Stock in favor of the
Hudson Officers. Such amendment to its Certificate of Incorporation will be made
by the Company regardless of whether it consummates the Bridge Financing or the
proposed Convertible Debt Financing.

     Based on the Conversion Price of the Preferred A Stock as of the Record
Date, the Fleming Funds may acquire approximately 49% of the outstanding Common
Stock after conversion of the Preferred A Stock (and assuming no other
conversion or exercise of outstanding options, warrants or other convertible
securities). Because the Preferred A Stock votes together with the Common Stock
as one class, the Fleming Funds would otherwise have approximately 49% of the
voting power, thereby enabling the Fleming Funds to significantly


                                       31


influence the ultimate determination on matters presented for shareholder vote
since, in most instances, shareholder approval is obtained upon the affirmative
vote of a majority of the voting shares cast at the meeting of shareholders at
which a quorum is present. The Proxy contained in the voting provision of the
designation of the Preferred A Stock currently acts to transfer approximately
twenty (20%) percent of the voting power held by the Fleming Funds to the
officers and directors of the Company.

Necessity for Shareholder Approval

     Because the removal of the provision for the Proxy from the designation of
the Preferred A Stock would result in the immediate increase in the percentage
of votes entitled to be cast by the Fleming Funds from 29% to approximately 49%
of all shares currently eligible to be cast by shareholders of the Company, the
removal of the Proxy could be deemed to result in a change of control for NASDAQ
purposes and, consequently, shareholder approval of such proposal would be
required under NASDAQ's Marketplace Rule 4350.

     In addition to shareholder approval required for an amendment to the
Certificate of Incorporation, NASDAQ Marketplace Rule 4350(i)(1)(B) requires
that a company listed on NASDAQ obtain shareholder approval prior to the
issuance of designated securities where the issuance or potential issuance will
result in a change of control of the company. Although the removal of the
provision providing for a Proxy granted by the holders of Preferred A Stock in
favor of the Hudson Officers may not technically involve an "issuance" of
securities, in essence the power to vote an aggregate of approximately 20% of
the currently outstanding voting securities would be returned to the Fleming
Funds, which would result in the Fleming Funds holding approximately 49% of the
voting securities of the Company. As this could be deemed a change of control of
the Company, the Company has submitted the proposal to amend the Certificate of
Incorporation to remove the Proxy from the designation of the Preferred A Stock
for shareholder approval.

Required Vote

     Approval by the shareholders of this amendment to the Company's Certificate
of Incorporation will require the affirmative vote of a majority of shares of
Common Stock and Preferred A Stock, voting together as one class, outstanding as
of the Record Date.

     It is anticipated that, because the Fleming Funds, as sole holder of the
Preferred A Stock, have a substantial interest in the amendment of the
Certificate of Incorporation to remove the Proxy, NASDAQ will not allow the
Preferred A Stock to be counted in determining shareholder approval required by
Rule 4350(i)(1)(B) with respect to the potential change in control of the
Company. Consequently, shareholder approval of this Proposal III for NASDAQ
purposes will also require the affirmative vote of the majority of shares of
Common Stock voted at the Annual Meeting, provided a quorum is present.


                                       32


Recommendation

     The Board of Directors believes that it is in the best interests of the
Company that the shareholders authorize the amendment to the Certificate of
Incorporation to remove the provision providing for a proxy from the designation
of the Preferred A Stock.

     THE BOARD OF DIRECTORS RECOMMENDS THAT SHAREHOLDERS VOTE FOR PROPOSAL III
TO AUTHORIZE THE COMPANY TO AMEND ITS CERTIFICATE OF INCORPORATION TO REMOVE THE
PROVISION IN THE DESIGNATION OF PREFERRED A STOCK PROVIDING FOR A PROXY IN FAVOR
OF CERTAIN HUDSON OFFICERS.


                                       33


                                   PROPOSAL IV

                    TO AMEND THE CERTIFICATE OF INCORPORATION
                   TO REMOVE THE CONVERSION PRICE RESTRICTION
              FROM THE DESIGNATION OF THE SERIES A PREFERRED STOCK

     The Board of Directors of the Company has adopted a resolution declaring
the advisability of, and submits to the shareholders for approval, a proposal to
authorize an amendment to Section 5(d)(ii) of paragraph 5 of the Company's
Certificate of Incorporation, substantially in the form of Exhibit A attached
hereto, to remove the provision in the designation of Preferred A Stock that
establishes a Conversion Price Floor of not less than $1.78 per common share
(the weighted average market price of the Common Stock of the Company at the
time the Preferred A Stock was issued) with respect to the adjustment of the
Conversion Price of the Preferred A Stock in the event of an Additional Issuance
by the Company for consideration per share less than the Conversion Price in
effect immediately prior to such Additional Issuance by the Company.

Reason for the Proposed Amendment

     As discussed herein above, the Company is in need of additional financing
such as that contemplated by the Bridge Financing and the proposed Convertible
Debt Financing in order to be able to support its operating activities prior to
the end of 2002. Due, however, to the restrictions set forth in the Fleming
Purchase Agreements with respect to the issuances or sales of convertible
securities for per share consideration below the Conversion Price then in
effect, based upon the Conversion Rate of the Notes to be offered in the
Convertible Debt Financing and the conversion rate of the Exchange Notes to be
issued in the Note Exchange, in each case calculated as of the Company's market
price on the Record Date, the Company would not be able to proceed with the
Convertible Debt Financing or the Note Exchange without the prior written
consent of the Fleming Funds. The Fleming Funds, however, have agreed to consent
to the Convertible Debt Financing and the Note Exchange. As consideration for,
among other things, the consent of the Fleming Funds to the Convertible Debt
Financing and the Note Exchange, the Company, at the request of the Fleming
Funds, has agreed to amend its Certificate of Incorporation to remove the
Conversion Price Floor from the designation of the Preferred A Stock. Such
amendment to its Certificate of Incorporation will be made regardless of whether
the Company consummates the Bridge Financing or the proposed Convertible Debt
Financing.

     The Company is subject to NASDAQ Marketplace Rule 4351 which restricts the
disparate reduction or restriction of the voting rights of existing shareholders
of common stock registered under Section 12 of the Securities Exchange Act of
1934, through any corporate action or issuance. The holders of the Preferred A
Stock vote together with the Common Stock as one class based upon the number of
shares of Common Stock into which the Preferred A Stock is convertible at the
Conversion Price then in effect. Following the removal of the Conversion Price
Floor, the Conversion Price, upon an event causing a subsequent downward
adjustment as discussed more fully below in the section entitled "Necessity for
Shareholder Approval," could be adjusted to a price well below the Conversion
Price Floor. The number of shares of Common Stock into which the Preferred A
Stock is convertible would increase as would the votes held by the holders of
Preferred A Stock. As NASDAQ would most likely view the resulting unlimited


                                       34


downward adjustment of the Preferred A Stock as a disparate reduction or
restriction to the holders of the Company's Common Stock, the Company will
maintain a floor on the Conversion Price of the Preferred A Stock solely as it
relates to the voting rights of such shares. Consequently, for calculating the
number of shares of Common Stock into which a share of Preferred A Stock is
convertible for purposes of determining the votes held by such share of
Preferred A Stock, the Conversion Price shall be the higher of (a) the
Conversion Price then in effect, or (b) $1.78.

Necessity For Shareholder Approval

     In addition to shareholder approval for an amendment to the Certificate of
Incorporation to remove the Conversion Price Floor, NASD Marketplace Rule
4350(i)(1)(D)(ii) requires that a company listed on NASDAQ obtain shareholder
approval prior to a transaction (other than a public offering) involving the
issuance or potential issuance of common stock (or securities convertible into
or exercisable for common stock) equal to 20% or more of the common stock or 20%
or more of the voting power outstanding before such issuance for less than the
greater of book or market value of the stock.

     The removal of the Conversion Price Floor would allow for the downward
adjustment of the Conversion Price of the Preferred A Stock to a price below the
Conversion Price Floor. The Conversion Price Floor is in place because the
initial issuance of the Preferred A Stock was in excess of 20% of the
outstanding shares of Common Stock at that time and the Conversion Price Floor
was the weighted average market price of the Common Stock at the time the
Preferred A Stock was issued (the "Preferred Stock Market Price"). As the
Company believed that shareholder approval for the initial issuance of the
Preferred A Stock was not deemed to be required, the Company did not obtain
shareholder approval for such initial issuance of the Preferred A Stock. The
removal of the Conversion Price Floor, however, could permit the Conversion
Price to fall below the Preferred Share Market Price upon the occurrence of an
event including, without limitation (i) the payment by the Company of a dividend
in shares of its Common Stock, (ii) the subdivision by the Company of its
outstanding Common Stock, (iii) the distribution by the Company of its assets
(other than cash dividends paid out of earnings in the ordinary course of
business), or (iv) upon the issuance by the Company of Common Stock or
securities convertible into or exchangeable for shares of Common Stock at a per
share consideration below the then-effective Conversion Price. As the removal of
the Conversion Price Floor may be deemed an issuance or potential issuance of
Common Stock equal to 20% or more of the Common Stock outstanding before the
issuance of the Preferred A Stock for less than the greater of book or market
value of the Common Stock at such issuance, the proposal to amend the Company's
Certificate of Incorporation to remove the Conversion Price Floor from the
designation of the Preferred A Stock has been submitted for shareholder
approval.

     The Fleming Funds have agreed to waive the anti-dilution adjustment of the
Conversion Price of the Preferred A Stock with respect to the issuance of the
Convertible Notes and the Exchange Notes, in each case at a conversion rate
below the Conversion Price of the Preferred A Stock at the time of issuance.
Such waiver, however, will not cover anti-dilution adjustment to the Conversion
Price of the Preferred A Stock resulting from the conversion of the Convertible
Notes or the Exchange Notes for the underlying shares of Common Stock. The
Fleming Funds have also agreed to waive the anti-dilution adjustment of the
Conversion Price of


                                       35


the Preferred A Stock with respect to the Company's obligation to issue the
Convertible Note Warrants and the Exchange Note Warrants, such waiver to be in
effect up to, but not including, the exercise of such warrants.

     To the extent that the Convertible Notes, Exchange Notes and Preferred A
Stock are converted, and the Convertible Note Warrants and Exchange Note
Warrants are exercised, in each case for shares of Common Stock, the interests
of the Company's existing shareholders will be diluted. Moreover, the conversion
rate of the Convertible Notes and Exchange Notes and the exercise price of the
Convertible Note Warrants and Exchange Note Warrants will provide for, and the
Conversion Price of the Preferred A Stock currently provides for, anti-dilution
adjustment of their respective conversion rate or exercise price in the event of
an Additional Issuance for per share consideration below the then-effective
conversion rate or exercise price, as the case may be. In such case, the
conversion rate of the Convertible Notes, Exchange Notes and Preferred A Stock
and the exercise price of the Convertible Note Warrants and Exchange Note
Warrants would be adjusted to such lower prices, resulting in a proportionate
increase in the number of shares of Common Stock issuable upon conversion or
exercise, as the case may be of such securities, further diluting the interests
of the Company's existing shareholders. As a result of the foregoing
anti-dilution features, the holders of the Convertible Notes, Exchange Notes and
Warrants will have, and the holders of the Preferred A Stock currently have,
protection of their prospective percentage interest in the Company upon the
occurrence of certain subsequent diluting events. Existing shareholders of the
Company do not have such protection and, therefore, would experience dilution to
their respective percentage interest in the Company upon a subsequent diluting
event.

     The potential for the issuance of additional shares of Common Stock
resulting from such anti-dilution protection coupled with the conversion feature
of the Convertible Notes, Exchange Notes, Preferred A Stock and the exchange
feature of the Convertible Note Warrants and Exchange Note Warrants, as the case
may be, could create downward pressure on the market price of the Company's
Common Stock, increasing the possibility that an Additional Issuance by the
Company would be for consideration below the then-effective conversion rates
and/or exercise prices of the Convertible Notes, Exchange Notes, Preferred A
Stock, Convertible Note Warrants and Exchange Note Warrants, in which case such
issuance would trigger such anti-dilution adjustment. To the extent that the
Convertible Notes, Exchange Notes and Preferred A Stock are converted, and the
Convertible Note Warrants and Exchange Note Warrants are exercised, the increase
in the shares of Common Stock issued resulting from such anti-dilution
adjustment would, in addition to the dilutive effect to the percentage interest
of the existing shareholders, negatively impact the per share book value of the
Company and could impair the Company's ability to raise additional capital
through the sale of equity securities.

Required Vote

     Approval by the shareholders of an amendment to the Certificate of
Incorporation will require the affirmative vote of a majority of shares of
Common Stock and Preferred A Stock, voting together as one class, outstanding as
of the Record Date.

     It is anticipated that, because the Fleming Funds, as sole holder of the
Preferred A Stock, have a substantial interest in the amendment of the
Certificate of Incorporation to remove


                                       36


the Conversion Price Restriction, NASDAQ will not allow the Preferred A Stock to
be counted in determining shareholder approval required by Rule
4350(i)(1)(D)(ii) with respect to the potential issuance of in excess of 20% of
the outstanding common stock below the greater of book or market value.
Consequently, shareholder approval of this Proposal IV for NASDAQ purposes will
also require the affirmative vote of the majority of shares of Common Stock
voted at the Annual Meeting, provided a quorum is present.

Recommendation

     The Board of Directors believes that it is in the best interests of the
Company that the shareholders authorize the amendment to the Certificate of
Incorporation to remove the Conversion Price Restriction from the designation of
the Preferred A Stock.

     THE BOARD OF DIRECTORS RECOMMENDS THAT SHAREHOLDERS VOTE FOR PROPOSAL IV TO
AUTHORIZE THE COMPANY TO AMEND ITS CERTIFICATE OF INCORPORATION TO REMOVE THE
CONVERSION PRICE RESTRICTION FROM THE DESIGNATION OF PREFERRED A STOCK.

                                   PROPOSAL V

                       TO AUTHORIZE THE BOARD OF DIRECTORS
               TO AMEND THE COMPANY'S CERTIFICATE OF INCORPORATION
                 TO INCREASE THE NUMBER OF AUTHORIZED SHARES OF
            COMMON STOCK FROM 20,000,000 SHARES TO 50,000,000 SHARES

     The Board of Directors has adopted a resolution approving and recommending
to the Company's shareholders, for their approval, the authorization for the
Board, in its discretion, to amend the Certificate of Incorporation of the
Company, substantially in the form of Exhibit A attached hereto, to provide for
an increase in the authorized number of shares of Common Stock of the Company
from 20,000,000 shares to 50,000,000 shares.

     As of the Record Date there were 5,165,020 shares of the Company's Common
Stock issued and outstanding and options, warrants and other convertible
securities outstanding (whether or not currently exercisable), other than the
Preferred A Stock, to acquire approximately 2,165,229 shares of Common Stock. In
addition, as of the Record Date, an aggregate of 116,629 Preferred A Stock were
issued and outstanding, which if converted in full, together with any accrued
dividends thereon, based upon the current Conversion Price would result in the
issuance of an aggregate of approximately 4,910,695 shares of Common Stock.
Other than the holders of the Preferred A Stock, the holders of outstanding
options, warrants and other convertible securities of the Company (whether or
not currently exercisable) as of the Record Date are not deemed to be
shareholders of the Company and, consequently will not be entitled to vote at
the Annual Meeting for the Proposals set forth in this Proxy Statement. If the
shareholders approve Proposal I above authorizing the Company to enter into the
Convertible Debt Financing and Proposal II authorizing the Company to issue the
Exchange Notes, the Convertible Notes and Exchange Notes to be issued by the
Company will be eligible for immediate conversion into shares of Common Stock
based upon the average of the closing price of the Company's Common Stock as
reported on the NASDAQ SmallCap Market for the five business days prior to the
closing date of the Convertible Debt Financing or the Note Exchange (to the
extent that the Convertible Debt Financing is not approved by the shareholders
at the Annual Meeting). The Convertible Notes and Exchange Notes to be issued by
the Company as well as the Preferred A Stock, to the extent that the
shareholders approve Proposal IV above authorizing the Company to amend its
Certificate of Incorporation to remove the Conversion Price Floor from the
designation of the Preferred A Stock, will each provide for full adjustment of
their respective conversion rate in the event of an Additional Issuance by the
Company at a per share price below their respective conversion rate then in
effect. In such cases, the number of shares of Common Stock issuable upon
conversion of the Convertible Notes, the Exchange Notes and the Preferred A
Stock will be proportionately increased.

     Finally, the Company is contemplating a proposed public offering (the
"Public Rights Offering") that will give holders of its Common Stock the right
(the "Stock Purchase Rights") to purchase additional shares of Common Stock
based upon a ratio of Stock Purchase Rights to outstanding shares of Common
Stock to be determined by the Company. The Company anticipates the aggregate
proceeds of such Public Rights Offering, which proceeds may include the
application of the outstanding principal and accrued interest of the Convertible
Notes and the Exchange Notes, to be within a range of $2,000,000 to $5,000,000
with the


                                       38


exercise price of the Stock Purchase Rights to be offered at a discount to
market at a price to be determined by the Company.

Reason for the Proposed Amendment

     The Company believes that, in addition to the authorized but unissued
shares reserved for issuance in the event of the exercise and/or conversion, as
the case may be, of currently outstanding options and warrants as well as
options available for future grant under the Company's stock option plans, it
would have sufficient authorized shares of Common Stock to cover the conversion
of the currently outstanding Preferred A Stock at the Conversion Price currently
in effect, the conversion of the Convertible Notes and Exchange Notes
contemplated to be issued in the Convertible Debt Financing and Note Exchange,
respectively at a conversion rate based upon the market price of its Common
Stock as of the Record Date and the exercise of Stock Purchase Rights issued at
the high end of the range in the proposed Public Rights Offering. The Company,
however, may not have a sufficient number of shares of authorized Common Stock
to issue in the event of the conversion or exercise of the Convertible Notes,
the Exchange Notes and/or the Preferred A Stock, or for other purposes,
subsequent to a downward adjustment of the respective conversion rate of the
Convertible Notes, Exchange Notes and Preferred A Stock.

     The additional authorized but unissued shares of Common Stock may also be
available to, among other things, raise capital in the future, finance future
acquisitions, retire debt or compensate employees. Although such additional
authorized shares may be used for anti-takeover purposes, the Company does not
anticipate such use in the immediate future. Additionally, the Company currently
has no plans, arrangements or understandings regarding future issuances of
Common Stock except in connection with the Company's stock option plans, the
Preferred A Stock and, to the extent that Proposals I and II authorizing the
Convertible Debt Financing and Note Exchange are approved by the shareholders,
the Convertible Notes and Convertible Note Warrants and the Exchange Notes and
the Exchange Note Warrants. The Company, however is contemplating the Public
Rights Offering discussed above.

     Once authorized, the additional shares of Common Stock may be issued with
approval of the Board of Directors but without further approval of the
shareholders unless shareholder approval is required by applicable law, rule or
regulation. Accordingly, this solicitation may be the only opportunity for the
Company's shareholders to approve certain financings, acquisitions, benefit
plans, recapitalizations and other corporate transactions to be undertaken by
the Company.

     None of the Common Stock of the Company has any preemptive rights. The
Preferred A Stock, in order to enable the holders thereof to maintain their
fully diluted percentage ownership of the Company, has preemptive rights to
purchase capital stock issued by the Company, including warrants or securities
convertible into capital stock, except for (a) pro rata dividends issued to all
holders of the Common Stock, (b) stock issued to employees, officers and
directors in connection with stock options or incentive plans approved by the
Board of Directors, (c) stock issued in connection with any merger, acquisition
or business combination, or (d) stock issued for consideration aggregating less
than $500,000 in any single transaction


                                       39


provided that all such transactions, in the aggregate, do not exceed $1,000,000.
Such preemptive rights terminate upon the conversion or redemption of the
Preferred A Stock, as the case may be.

Required Vote

     To be approved by the shareholders, this Proposal V requires the
affirmative vote of a majority of shares of Common Stock and Preferred A Stock,
voting together as one class, outstanding as of the Record Date.

Recommendation

     The Board of Directors believes that it is in the best interests of the
Company that the shareholders authorize the Board of Directors, in their
discretion, to amend the Certificate of Incorporation to increase the number of
authorized shares of Common Stock from 20,000,000 shares to 50,000,000 shares.

     THE BOARD OF DIRECTORS RECOMMENDS THAT SHAREHOLDERS VOTE FOR PROPOSAL V TO
AUTHORIZE THE BOARD OF DIRECTORS, IN THEIR DISCRETION, TO AMEND THE COMPANY'S
CERTIFICATE OF INCORPORATION TO INCREASE THE NUMBER OF AUTHORIZED SHARES OF
COMMON STOCK FROM 20,000,000 SHARES TO 50,000,000 SHARES.

                                    EXHIBIT A

                              FORM OF AMENDMENT TO

                        THE CERTIFICATE OF INCORPORATION

     The first paragraph of Article 5 of the Certificate of Incorporation, which
refers to the authorized shares of the corporation, is hereby amended to read as
follows:

          "(5). The total number of shares of capital stock which the Company
     shall have authority to issue is Fifty-Five Million (55,000,000) shares, of
     which Fifty Million (50,000,000) shares shall be Common Stock, par value
     $.01 per share, and Five Million (5,000,000) shares shall be Preferred
     Stock, par value $.01 per share."

     The Certificate of Incorporation is amended as authorized by Section 801 of
the Business Corporation Law to change the provisions of the Series A Preferred
Stock relating to Voting and to adjustment of the Conversion Price.

     To effectuate the foregoing:

               (a) Section 4(a) is deleted in its entirety and a new Section
          4(a) is hereby inserted in lieu and instead thereof to read as
          follows:

                    "(a) General. In addition to any voting rights provided in
               the Corporation's Certificate of Incorporation or by law, the
               Series A Preferred Stock shall vote together with the Common
               Stock as a single class on all actions to be voted on by the
               stockholders of the Corporation. Each share of Series A Preferred
               Stock shall entitle the holder thereof 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 Series A Preferred Stock is then convertible; provided,
               however, that, notwithstanding any other provision to the
               contrary herein, as the same relates solely to the voting rights
               of the Series A Preferred Stock as set forth in this Section 4,
               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, or (b) $1.78. The holders of
               Series A Preferred Stock shall be entitled to notice of any
               stockholder's meeting in accordance with the By-Laws of the
               Corporation."

               (b) Section 5(d)(ii) is deleted in its entirety and a new Section
          5(d)(ii) is hereby inserted in lieu and instead thereof to read as
          follows:

                    "(ii) Issuance of Additional Shares of Stock. If the
               Corporation shall (except as hereinafter provided) issue or sell
               Additional Shares of Stock in exchange for consideration in an
               amount per Additional Share of Stock less than the Conversion
               Price in effect immediately prior to such issuance or sale of
               Additional Shares of Stock, then the Conversion Price as to the
               Common Stock into which the Series A Preferred Stock is
               convertible immediately prior to such adjustment shall be
               adjusted to equal the consideration paid per Additional Share of
               Stock. The provisions of this Section 5(d)(ii) shall not apply to
               any issuance of Additional Shares of Common Stock for which an
               adjustment is provided under Section 5(d)(i) or which are
               dividends or distributions received by the holders of the Series
               A Preferred Stock pursuant to Section 2(b) hereof."
