                                     Part I

Item 1. Description of Business

General

Hudson  Technologies,  Inc.,  incorporated under the laws of New York on January
11,  1991,  together  with  its  subsidiaries  (collectively,  "Hudson"  or  the
"Company"), primarily sells refrigerants,  provides RefrigerantSide(TM) Services
performed at a customer's site,  consisting of system  decontamination to remove
moisture,  oils and other  contaminants  and  recovery  and  reclamation  of the
refrigerants used in commercial air conditioning and refrigeration  systems. The
Company  operates  through  its  wholly  owned  subsidiary  Hudson  Technologies
Company.

The Company's  Executive Offices are located at 275 North Middletown Road, Pearl
River, New York and its telephone number is (914) 735-6000.

Industry background

The production and use of refrigerants containing  chlorofluorocarbons  ("CFCs")
and hydrochlorofluorocarbons  ("HCFCs"), the most commonly used refrigerants are
subject  to  extensive  and  changing  regulation  under  the Clean Air Act (the
"Act").  The Act, which was amended during 1990 in response to evidence  linking
the use of CFCs to damage to the earth's  ozone layer,  prohibits  any person in
the  course  of   maintaining,   servicing,   repairing  and  disposing  of  air
conditioning or refrigeration  equipment, to knowingly vent or otherwise release
or dispose of ozone depleting substances used as refrigerants.  That prohibition
also applies to substitute,  non-ozone depleting  refrigerants.  The Act further
requires  the  recovery of  refrigerants  used in  residential,  commercial  and
industrial air conditioning and refrigeration systems.

In addition, the Act prohibited production of CFC refrigerants effective January
1, 1996 and  limits the  production  of  refrigerants  containing  HCFCs,  which
production is scheduled to be phased out by the year 2030.

Owners,  operators and companies servicing cooling equipment are responsible for
the integrity of their systems  regardless of the refrigerant being used and for
the responsible management of their refrigerant.

Products and Services

Refrigerant Sales

The  Company  sells  reclaimed  and virgin  (new)  refrigerants  to a variety of
customers  in  various  segments  of  the  air  conditioning  and  refrigeration
industry.  Virgin  refrigerants are primarily purchased by the Company from E.I.
DuPont de Nemours  and Company  ("DuPont")  as part of the  Company's  strategic
alliance  with  DuPont  (see  "Strategic  Alliance"  below),  and  resold by the
Company,  typically at wholesale.  In addition,  the Company regularly purchases
used  or  contaminated   refrigerants   from  many  different   sources,   which
refrigerants  are then  reclaimed,  using the Company's high volume  proprietary
reclamation equipment, and resold by the Company.

RefrigerantSide(TM) Services

The Company  provides  services that are performed at a customer's  site through
the use of portable, high volume,  high-speed proprietary reclamation equipment,
including its patented Zugibeast(R)  reclamation machine. These services consist
of RefrigerantSide(TM)  Services,  which encompass system  decontamination,  and
refrigerant  recovery  and  reclamation.  The  Company  also  provides  complete
refrigerant  management  services,  which include  testing and banking  services
tailored to individual  customer  requirements.  Hudson also separates `crossed'
(i.e.;  commingled)  refrigerants  and provides  re-usable  cylinder  repair and
hydrostatic testing services.

Strategic Alliance

In January  1997,  the Company  entered into an Industrial  Property  Management
Segment  Marketer  Appointment  and  Agreement  and  Refrigeration   Reclamation
Services Agreement with E.I. DuPont de Nemours and Company ("DuPont'),  pursuant
to which the Company (i) provides recovery, reclamation,  separation,  packaging
and  testing  services   directly  to  DuPont  for  marketing  through  DuPont's
Authorized  Distributor  Network and (ii) markets DuPont's SUVA(TM)  refrigerant
products to selected market segments together with the Company's reclamation and
refrigerant   management   services.   Under  the  agreement,   100%  of  virgin
refrigerants  provided to specified  market segment  customers must be purchased
from DuPont.

In  addition,  in  January  1997,  the  Company  entered  into a Stock  Purchase
Agreement with DuPont and DuPont Chemical and Energy  Operations,  Inc. ("DCEO")
pursuant to which the Company  issued to DCEO 500,000  shares of Common Stock in
consideration  of $3,500,000 in cash.  Concurrently,  the parties entered into a
Standstill Agreement,  Shareholders' Agreement and Registration Agreement which,
among other  things,  provide  that (i) subject to certain  exceptions,  neither
DuPont nor any  corporation  or entity  controlled  by DuPont will,  directly or
indirectly,  acquire any shares of any class of capital  stock of the Company if
the effect of such acquisition  would be to increase  DuPont's  aggregate voting
power to greater than 20% of the total  combined  voting  power  relating to any
election of  directors;  (ii) at DuPont's  request,  the Company  will cause two
persons  designated by DCEO and DuPont to be elected to the  Company's  Board of
Directors; and (iii) subject to certain exceptions, DuPont will have a five-year
right of first refusal to purchase  shares of Common Stock sold by the Company's
principal  shareholders.  The Company also granted to DuPont  certain demand and
"piggy-back" registration rights with respect to the shares.

The Company has sold certain reclaimed refrigerants to DuPont.

During  the years  ended  December  31,  1999 and  1998,  revenues  from  DuPont
aggregated approximately $975,000 and $6,434,000, respectively. In 1999 revenues
with DuPont decreased  primarily due to the fact that the Company ceased selling
reclaimed  refrigerants directly to DuPont and now sells reclaimed  refrigerants
directly to DuPont's network of authorized distributors.

Suppliers

The  Company's  financial  performance  is in part  dependent  on its ability to
obtain  sufficient  quantities  of  virgin  and  reclaimable  refrigerants  from
manufacturers,  wholesalers,  distributors,  bulk gas  brokers  and  from  other
sources within the air conditioning and refrigeration and automotive aftermarket
industries, and on corresponding demand for refrigerants. To the extent that the
Company is unable to obtain sufficient quantities of refrigerants in the future,
or resell  refrigerants  at a profit,  the  Company's  financial  condition  and
results of operations would be materially adversely affected.

Customers

The Company  provides its services to commercial,  industrial  and  governmental
customers, as well as to refrigerant wholesalers,  distributors, contractors and
to  refrigeration  equipment  manufacturers.  Agreements  with larger  customers
generally provide for standardized pricing for specified services.

For the year ended December 31, 1999, one customer accounted for an aggregate of
17% of the  Company's  revenues.  For the year  ended  December  31,  1998,  two
customers accounted for an aggregate of 42% of the Company's revenues.  The loss
of a principal  customer or a decline in the economic prospects and purchases of
the Company's  products or services by any such  customer,  as incurred in 1999,
would have a material  adverse  effect on the Company's  financial  position and
results of operations.


                                       4

Marketing

Marketing programs are conducted through the efforts of the Company's  executive
officers,  Company sales  personnel,  and third parties.  Hudson employs various
marketing methods,  including direct mailings,  technical  bulletins,  in-person
solicitation,   print   advertising,   response  to   quotation   requests   and
participation in trade shows.

The Company's  sales  personnel  are  compensated  on a commission  basis with a
guaranteed  minimum draw. The Company's  executive  officers devote  significant
time and effort to customer relationships.

Competition

The  Company  competes  primarily  on the basis of price,  breadth  of  services
offered (including RefrigerantSide(TM) Services and other on-site services), and
performance of its high volume, high-speed equipment used in its operations.

The Company competes with numerous regional companies, which provide refrigerant
recovery and/or reclamation  services,  as well as companies marketing reclaimed
and  new  alternative  refrigerants.  Certain  of  such  competitors,  including
National  Refrigerants,  Inc.,  Refron,  Inc.,  and  Environmental  Technologies
Company, Inc., which may possess greater financial, marketing,  distribution and
other resources for the sale and  distribution of refrigerants  than the Company
and, in some  instances,  provide  services or  products  over a more  extensive
geographic area than the Company.

The refrigerant recovery and reclamation industry is relatively new and emerging
competition  from existing  competitors  and new market  entrants is expected to
increase.   Demand  and  market   acceptance  for  Hudson's   newly   introduced
RefrigerantSide(TM)  services,  and for  the  Company's  refrigerant  management
products and services are subject to a high degree of uncertainty.  There can be
no assurance that the Company will be able to compete  successfully or penetrate
this market as rapidly as it anticipates.

Insurance

The Company  carries  insurance  coverage the Company  considers  sufficient  to
protect the Company's  assets and operations.  The Company  currently  maintains
general commercial  liability insurance and excess liability coverage for claims
up to $7,000,000 per occurrence and $7,000,000 in the aggregate. There can be no
assurance that such insurance  will be sufficient to cover  potential  claims or
that an  adequate  level  of  coverage  will be  available  in the  future  at a
reasonable  cost. The Company  attempts to operate in a professional and prudent
manner  and to reduce its  liability  risks  through  specific  risk  management
efforts,  including employee training.  Nevertheless,  a partially or completely
uninsured claim against the Company, if successful and of sufficient  magnitude,
would have a material adverse effect on the Company.

The refrigerant industry involves potentially significant risks of statutory and
common law liability for environmental  damage and personal injury. The Company,
and in certain instances, its officers,  directors and employees, may be subject
to claims arising from the Company's on-site or off-site services, including the
improper release,  spillage, misuse or mishandling of refrigerants classified as
hazardous or non-hazardous  substances or materials. The Company may be strictly
liable  for  damages,  which  could be  substantial,  regardless  of  whether it
exercised due care and complied with all relevant laws and regulations.

Hudson  maintains  environmental  impairment  insurance of $1,000,000 for events
occurring  subsequent  to  November  1996.  There can be no  assurance  that the
Company will not face claims  resulting in  substantial  liability for which the
Company is uninsured, that hazardous substances or materials are not or will not
be present  at the  Company's  facilities,  or that the  Company  will not incur
liability for  environmental  impairment  or personal  injury (see Item 3 "Legal
Proceedings").

Government Regulation

The business of refrigerant  reclamation and management is subject to extensive,
stringent and frequently changing federal,  state and local laws and substantial
regulation   under  these  laws  by   governmental   agencies,   including   the
Environmental  Protection Agency ("EPA"),  the United States Occupational Safety
and Health Administration and the United States Department of Transportation.


                                       5
<PAGE>


Among other things,  these  regulatory  authorities  impose  requirements  which
regulate  the  handling,  packaging,  labeling,  transportation  and disposal of
hazardous and non-hazardous  materials and the health and safety of workers, and
require the Company  and, in certain  instances,  its  employees,  to obtain and
maintain licenses in connection with its operations.  This extensive  regulatory
framework imposes significant compliance burdens and risks on the Company.

Hudson and its customers are subject to the  requirements  of the Clean Air Act,
and the  regulations  promulgated  thereunder by the EPA, which make it unlawful
for any person in the course of maintaining, servicing, repairing, and disposing
of air conditioning or refrigeration  equipment,  to knowingly vent or otherwise
release  or dispose  of ozone  depleting  substances,  and  non-ozone  depleting
substitutes, used as refrigerants.

Pursuant  to the Clean Air Act,  reclaimed  refrigerant  must  satisfy  the same
purity standards as newly manufactured refrigerants in accordance with standards
established by the Air Conditioning and Refrigeration Institute ("ARI") prior to
resale to a person  other  than the  owner of the  equipment  from  which it was
recovered.  The ARI and the EPA administer  certification  programs  pursuant to
which  applicants are certified to reclaim  refrigerants  in compliance with ARI
standards.  Under  such  programs,  the ARI  issues  a  certification  for  each
refrigerant and conducts  periodic  inspections and quality testing of reclaimed
refrigerants.

The Company has obtained ARI  certification for most refrigerants at each of its
reclamation facilities,  and is certified by the EPA. The Company is required to
submit  periodic  reports to the ARI and pay annual  fees based on the number of
pounds of  reclaimed  refrigerants.  Certification  by the ARI is not  currently
required to engage in the refrigerant management business.

During February 1996, the EPA published proposed regulations, which, if enacted,
would require participation in third-party certification programs similar to the
ARI program.  Such proposed regulations would also require laboratories designed
to test  refrigerant  purity  to  undergo  a  certification  process.  Extensive
comments to these  proposed  regulations  were  received by the EPA.  The EPA is
still considering  these comments and no further or additional  regulations have
been proposed or published.

In addition,  the EPA has established a mandatory  certification program for air
conditioning and refrigeration  technicians.  Hudson's  technicians have applied
for or obtained such certification.

The  Company  is  subject  to   regulations   adopted  by  the   Department   of
Transportation  which  classify  most  refrigerants  handled  by the  Company as
hazardous   materials  or  substances  and  impose  requirements  for  handling,
packaging, labeling and transporting refrigerants.

The  Resource  Conservation  and  Recovery Act of 1976  ("RCRA")  requires  that
facilities that treat,  store or dispose of hazardous wastes comply with certain
operating  standards.  Before  transportation  and disposal of hazardous  wastes
off-site,  generators  of such  waste must  package  and label  their  shipments
consistent  with detailed  regulations  and prepare a manifest  identifying  the
material and stating its destination. The transporter must deliver the hazardous
waste in  accordance  with the manifest to a facility with an  appropriate  RCRA
permit.  Under RCRA,  impurities  removed from  refrigerants  consisting of oils
mixed with water and other contaminants are not presumed to be hazardous waste.

The  Emergency  Planning and  Community  Right-to-Know  Act of 1986 requires the
annual  reporting of  Emergency  and  Hazardous  Chemical  Inventories  (Tier II
reports) to the various states in which the Company  operates and to file annual
Toxic Chemical Release Inventory Forms with the EPA.

The Comprehensive Environmental Response, Compensation and Liability Act of 1980
("CERCLA"),  establishes  liability for clean-up costs and environmental damages
to current  and former  facility  owners and  operators,  as well as persons who
transport  or arrange for  transportation  of hazardous  substances.  Almost all
states,  including New York, have similar  statutes  regulating the handling and
storage of hazardous substances, hazardous wastes and non-hazardous wastes. Many
such statutes impose  requirements,  which are more stringent than their federal
counterparts.  The Company could be subject to substantial liability under these
statutes to private parties and government  entities,  in some instances without
any fault, for fines, remediation costs and environmental damage, as a result of
the mishandling, release, or existence of any hazardous substances at any of its
facilities.

The  Occupational  Safety and Health Act of 1970 mandates  requirements for safe
work place for employees and special procedures and measures for the handling of
certain  hazardous and toxic substances.  State laws, in certain  circumstances,
mandate  additional  measures for facilities  handling specified  materials.  In
February 1999, an inspection was performed,


                                       6
<PAGE>


at one of the  Company's  facilities,  by the  Occupational  Safety  and  Health
Administration in response to a complaint by an unnamed third party. The Company
has not received a report on the results of that inspection.

The Company  believes  that it is in  substantial  compliance  with all material
regulations relating to its material business operations.  However, there can be
no  assurance  that Hudson  will be able to  continue to comply with  applicable
laws,  regulations and licensing  requirements.  Failure to comply could subject
the Company to civil remedies,  substantial  fines,  penalties,  injunction,  or
criminal sanctions.

Quality Assurance & Environmental Compliance

The  Company  utilizes  in-house  quality  and  regulatory   compliance  control
procedures.  Hudson maintains its own analytical testing  laboratories to assure
that  reclaimed  refrigerants  comply  with ARI  purity  standards  and  employs
portable  testing  equipment when performing  on-site services to verify certain
quality  specifications.  The Company employs three persons engaged full-time in
quality  control  and  to  monitor  the  Company's   operations  for  regulatory
compliance.

Employees

The Company has  approximately  99 full and  part-time  employees  including air
conditioning and refrigeration technicians,  chemists,  engineers, and sales and
administrative personnel.

None of the Company's employees are represented by a union. The Company believes
that its employee relations are good.

Patents and Proprietary Information

The  Company  holds a  United  States  patent  relating  to  various  high-speed
equipment  components  and a process to reclaim  refrigerants,  and a registered
trademark  for its  "Zugibeast(R)".  The patent  expires in  January  2012.  The
Company  believes  that patent  protection  is important to its business and has
received a notice of allowance for an additional  United States patent  relating
to a high speed refrigerant  recovery  process.  There can be no assurance as to
the breadth or degree of  protection  that patents may afford the Company,  that
any patent  applications  will result in issued patents or that patents will not
be  circumvented or  invalidated.  Technological  development in the refrigerant
industry may result in extensive  patent filings and a rapid rate of issuance of
new patents.  Although the Company  believes  that its existing  patents and the
Company's  equipment  do not and will not  infringe  upon  existing  patents  or
violate proprietary rights of others, it is possible that the Company's existing
patent  rights  may not be valid or that  infringement  of  existing  or  future
patents or violations of  proprietary  rights of others may occur.  In the event
the  Company's  equipment  infringe or are alleged to infringe  patents or other
proprietary  rights of others,  the Company may be required to modify the design
of its  equipment,  obtain a license  or defend a possible  patent  infringement
action.  There can be no assurance  that the Company will have the  financial or
other  resources  necessary  to  enforce  or  defend  a patent  infringement  or
proprietary  rights  violation action or that the Company will not become liable
for damages.

The Company also relies on trade secrets and proprietary  know-how,  and employs
various methods to protect its technology.  However, such methods may not afford
complete  protection  and  there  can  be no  assurance  that  others  will  not
independently  develop such know-how or obtain access to the Company's know-how,
concepts,  ideas and  documentation.  Failure to protect its trade secrets could
have a material adverse effect on the Company.

Item 3. Legal Proceedings

During  June 1995,  United  Water of New York Inc.  ("United")  alleged  that it
discovered  that  two of its  wells  within  close  proximity  to the  Company's
Hillburn, New York facility showed elevated levels of refrigerant contamination,
specifically Trichlorofluoromethane (R-11). During December 1997, United alleged
that it discovered levels of Dichlorodifluoromethane  (R-12) in two of its wells
within  close  proximity  to the  Company's  facility,  and has alleged that the
Company is the  source.  Sampling  by the  Company of various  monitoring  wells
installed  around the  Company's  facilities  have been taken on a monthly basis
since August 1996 and have detected levels of R-11 in the groundwater,  but have
failed to  detect  any  levels  of R-12 in the  groundwater  in and  around  the
Company's facility.

In January  1998,  the  Company  agreed to install a  remediation  system at the
Company's  facility to remove any remaining R-11 levels in the groundwater under
and around the Company's facility. In August 1998, the New York State Department
of  Environmental  Conservation  ("DEC")  accepted  the  Company's  proposal and
requested that the Company proceed with the installation of the system. The cost
of this remediation system was $100,000.

In June 1998,  United  commenced  an action  against  the Company in the Supreme
Court of the State of New York,  Rockland County,  seeking damages in the amount
of $1.2  million  allegedly  sustained  as a  result  of the  foregoing  alleged
contamination.  In December 1998, United served an amended complaint asserting a
claim pursuant to the Resource


                                       8
<PAGE>


Conservation and Recovery Act, 42 U.S.C. ss. 6901, et. seq.  ("RCRA") In January
1999, the Company filed a motion to dismiss the RCRA cause of action.

On April 1, 1999, the Company reported a release at the Company's Hillburn,  New
York facility of what was ultimately  determined to be approximately  7,800 lbs.
of R-11, as a result of a failed hose connection to one of the Company's outdoor
storage tanks allowing  liquid R-11 to discharge from the tank into the concrete
secondary  containment area in which the subject tank was located.  An amount of
the R-11 escaped the secondary  containment  area through an open drain from the
secondary  containment area for removing  accumulated  rainwater and entered the
ground.  The  Company  immediately  commenced  excavation  operations  to remove
contaminated soil and has taken a number of other steps to mitigate and minimize
contamination,  including  acceleration  of  the  installation  of  the  planned
remediation system.

In April 1999,  the  Company was advised by United that one of its wells  within
close  proximity to the Company's  facility  showed  elevated  levels of R-11 in
excess of 200 ppb. and was taking certain steps and would be incurring  costs in
an attempt to  remediate  any  contamination.  In response to the  release,  the
Company requested,  and in May 1999, received permission from the DEC to operate
the planned remediation system pending negotiation and finalization of a Consent
Order covering the operation of the system.  The remediation system was put into
operation  on May 7, 1999.  The level of R-11 in the  affected  United well have
steadily  decreased  since June 1, after rising to a level in excess of 700 ppb.
and on March 13, 2000 was reduced to 5.5 ppb. In December  1999, a second United
well within close  proximity to the Company's  facility  began showing  elevated
levels  of  R-11 in  excess  of 5 ppb.  and  increased  to a high of 26 ppb.  in
February 2000. The Company  continues to work with the DEC,  United and with the
Company's  experts to determine the scope of any  contamination,  and to develop
plans for the  construction of a separate  remediation  system to directly treat
contaminated water from United's well.

In July 1999, United filed a motion seeking permission to amend its complaint in
the action it commenced  in June 1998 to allege  facts  relating to, and to seek
damages allegedly  resulting from the April 1, 1999 release. In August 1999, the
Company entered into a stipulation  accepting  service of the amended  complaint
subject to the  Company's  pending  motion to dismiss.  On August 26, 1999,  the
Court  issued a decision  which  granted the  Company's  motion to dismiss  that
portion of  United's  RCRA claims  which seek past  cleanup  costs,  and held in
abeyance a ruling whether United can assert a claim for  present/future  cleanup
under RCRA until the date of trial.  The Company  continues to defend the claims
asserted by United.

The Company carries $1,000,000 of pollution  liability  insurance per occurrence
and has put the insurance  carrier on notice of the release and possible  claims
of  United.  There can be no  assurance  that  this  action,  or any  settlement
thereof,  will be resolved in a manner  favorable  to the  Company,  or that the
ultimate outcome of any legal action or settlement,  or the effects of the April
1, 1999  release,  will not have a  material  adverse  effect  on the  Company's
financial condition and results of operations.

During March and April 1998,  six (6)  complaints,  each alleging  violations of
Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, were filed by a
total of eight  shareholders,  on behalf of themselves and all others  similarly
situated,  against the Company and certain of its officers and  directors in the
United States District Court for the Southern  District of New York. Each of the
complaints  alleged  that the  defendants,  among other  things,  misrepresented
material  information about the Company's  financial results and prospects,  and
its customer relationships.  In October 1998, a consolidated complaint on behalf
of the  plaintiffs  was served upon the Company.  In December 1998, a motion was
made on behalf of the Company to dismiss each of the claims asserted against the
Company in the consolidated  complaint.  On September 26, 1999, the Court issued
an opinion and order dismissing with prejudice three of the five claims asserted
by the  plaintiffs  and further  dismissing  the  remaining  two claims  without
prejudice  to the  plaintiffs  filing a second  amended  consolidated  complaint
within  thirty  (30) days of the date of the  Court's  opinion  and  order.  The
plaintiffs  failed to serve a second amended  consolidated  complaint,  and as a
result,  in  November  1999,  a  final  judgment  was  entered   dismissing  the
consolidated complaint in its entirety.

In June 1999,  an action  was  commenced  in the Baton  Rouge  Supreme  Court by
William Freeman and three others against the Company seeking unspecified damages
for  alleged  personal  injuries  allegedly  suffered  as a result of an ammonia
release at the  Company's  Louisiana  facility  in  January  1999.  The  Company
maintains that the allegations in the


                                       9
<PAGE>


complaint are without merit and that no damages were suffered by the  plaintiffs
in that action.  There can be no assurance  that this action,  or any settlement
thereof, will be resolved in a manner favorable to the Company.

The Company and its  subsidiaries  are subject to various  other  claims  and/or
lawsuits from both private and  governmental  parties  arising from the ordinary
course of business, none of which are material.

The number of record holders of the Company's Common Stock was approximately 250
as of March 13,  2000.  The Company  believes  that there are in excess of 4,000
beneficial owners of its Common Stock.

To date,  the Company has not declared or paid any cash  dividends on its Common
Stock. The payment of dividends,  if any, in the future is within the discretion
of the Board of  Directors  and will depend  upon the  Company's  earnings,  its
capital  requirements and financial condition,  borrowing  covenants,  and other
relevant factors. The Company presently intends to retain all earnings,  if any,
to finance the Company's operations and development of its business and does not
expect to  declare  or pay any cash  dividends  in the  foreseeable  future.  In
addition,  the Company has entered into a credit facility with CIT  Group/Credit
Finance Group, Inc. ("CIT") which,  among other things,  restricts the Company's
ability to declare or pay any  dividends on its capital  stock.  The Company has
obtained a waiver  from CIT to permit the payment of  dividends  on its Series A
Preferred Stock. The Series A Preferred Stock carries a dividend rate of 7%. The
Company will pay dividends,  in arrears,  on the Series A Preferred Stock,  semi
annually,  either in cash or additional shares, at the Company's option,  during
the first  two  years  after  which  dividends  will be paid in cash (see Item 6
"Management's  Discussion  and  Analysis of Financial  Condition  and Results of
Operations" - Liquidity).

During the three months ended December 31, 1999, the Company  granted options to
purchase 70,000 and 35,000 shares of common stock to certain employees  pursuant
to its 1994 and 1997 Stock  Option  Plans,  respectively.  With respect to these
grants,  the  Company  relied on the  exemption  from  registration  provided by
Section 4(2) under the Securities Act of 1933 as  transactions  by an issuer not
involving a public offering.

Overview

Sales of  refrigerants  continue  to  represent  a  significant  portion  of the
Company's  revenues.  The Company believes that in the industry  overall,  there
will be a trend towards lower sales prices,  volume and gross profit  margins on
refrigerant  sales in the  foreseeable  future,  which will  continue to have an
adverse effect on the Company's operating results.

Historically,  the Company has derived a majority of its revenues  from the sale
of  refrigerants.  The Company has changed its business  focus  towards  service
revenues   through   the   development   of  a   service   offering   known   as
RefrigerantSide(TM)  Services.  These  services  are  offered in addition to the
Company's traditional refrigerant management services, consisting principally of
recovery and  reclamation of refrigerants  used in commercial air  conditioning,
industrial  processing  and  refrigeration  systems.  Pursuant to this change in
business  focus,  the Company has developed,  and is currently  implementing,  a
strategic  business plan which provides for the creation of a network of service
depots and the exiting of certain operations which may not support the growth of
service sales.  Consistent with its plan, the Company anticipates a reduction in
automotive  refrigerant  sales  related  to the  sale of its  aerosol  packaging
equipment and the exit of the Congers, New York facility.

In March 1999,  the Company  completed the sale of its Series A Preferred  Stock
and  received net  proceeds of  $5,800,000.  The net proceeds of the sale of the
Company's  Series A  Preferred  Stock are being  used to  expand  the  Company's
service  offering  through a network of depots that  provide a full range of the
Company's on site  RefrigerantSide(TM)  Services and to provide working capital.
Management  believes  that  its   RefrigerantSide(TM)   Services  represent  the
Company's long term growth  potential.  However,  while the Company  believes it
will experience an increase in revenues from its  RefrigerantSide(TM)  Services,
in the  short  term,  such an  increase  will  not be  sufficient  to  offset  a
substantial  reduction in refrigerant  revenue. The Company expects that it will
incur  additional  expenses and losses  during the year related to the expansion
and development of its depot network.

The change in business focus towards revenues generated from service may cause a
material  reduction  in  revenues  derived  from  the sale of  refrigerants.  In
addition,  to the extent  that the Company is unable to obtain  refrigerants  on
commercially   reasonable   terms  or   experiences  a  decline  in  demand  for
refrigerants,  the Company could realize  reductions in refrigerant  processing,
and  possible  loss of revenues  which would have a material  adverse  effect on
operating results.

Results of Operations

Year ended December 31, 1999 as compared to year ended December 31, 1998

Revenues for 1999 were  $17,909,000,  a decrease of  $5,402,000  or 23% from the
$23,311,000  reported  during the  comparable  1998  period.  The  decrease  was
primarily attributable to lower revenues generated from a principal customer and
the lack of revenues from the Company's former subsidiary  Environmental Support
Solutions ("ESS"), which was sold in the first quarter of 1999, partially offset
by an increase in RefrigerantSide(TM) Services revenue. In addition, the Company
experienced a short fall of certain refrigerant product availability on a timely
basis to meet  certain of its  refrigerant  sales.  If the  Company is unable to
obtain  refrigerant  product in the  future,  the  Company  would  experience  a
reduction  in  refrigerant  revenues  beyond  the  reduction  that  the  Company
anticipates relating to its change in focus


                                       12
<PAGE>


towards service revenues and the reduction in automotive refrigerant sales which
would have a material adverse effect on operating results.

Cost of sales for 1999 were  $14,121,000,  a decrease of  $3,464,000 or 20% from
the $17,585,000  reported  during the comparable 1998 period  primarily due to a
reduction in refrigerant  revenues. As a percentage of sales, cost of sales were
79% of revenues for 1999, an increase  from the 75% reported for the  comparable
1998  period.  The  increase in cost of sales as a  percentage  of revenues  was
primarily attributable to an increase in labor and other operating costs and the
lack of revenues from ESS.

Operating  expenses for 1999 were $7,395,000,  a decrease of $720,000 or 9% from
the  $8,115,000  reported  during the comparable  1998 period.  The decrease was
primarily  attributable  to a lack of operating  expenses  from ESS offset by an
increase  in  depreciation  and  amortization  and  selling  expenses  primarily
associated  with the  expansion  of the  Company's  RefrigerantSide(TM)  Service
offering.

Other income  (expense) for 1999 was  $(348,000),  an increase of $81,000 or 30%
from the $(267,000)  reported  during the comparable  1998 period.  Other income
(expense)  includes interest expense of $454,000 and $399,000 for 1999 and 1998,
respectively, offset by other income of $106,000 and $132,000 for 1999 and 1998,
respectively.  The increase in interest  expense is primarily  attributed  to an
increase in borrowings  during 1999 as compared to 1998.  Other income primarily
relates to lease rental income.

No income taxes for the years ended December 31, 1999 and 1998 were  recognized.
The Company  recognized a reserve allowance against the deferred tax benefit for
the 1999 and 1998 losses.  The tax benefits  associated  with the  Company's net
operating loss carry forwards would be recognized to the extent that the Company
recognizes net income in future periods.

Net loss for 1999 was  $3,955,000 an increase of $1,299,000  from the $2,656,000
net loss reported  during the comparable  1998 period.  The increase in net loss
was primarily attributable to a lower volume of refrigerant sales.

Liquidity and Capital Resources

At  December  31,  1999,  the  Company  had  working  capital  of  approximately
$1,677,000, an increase of $1,624,000 from the $53,000 at December 31, 1998. The
increase  in  working  capital  is  primarily  attributable  to the  sale of the
Company's  Series A Convertible  Preferred  Stock  pursuant to which the Company
received net proceeds of $5,800,000 offset by the net losses incurred during the
year ended  December  31,  1999.  A  principal  component  of current  assets is
inventory.  At December 31, 1999, the Company had  inventories of $2,480,000,  a
decrease of $804,000  or 24% from the  $3,284,000  at  December  31,  1998.  The
Company's  ability to sell and replace its  inventory  on a timely basis and the
prices at which it can be sold are  subject,  among  other  things,  to  current
market  conditions  and the nature of  supplier or  customer  arrangements  (see
"Seasonality   and  Fluctuations  in  Operating   Results").   The  Company  has
historically  financed its working capital  requirements through cash flows from
operations,  the issuance of debt and equity  securities,  bank  borrowings  and
loans from officers.

Net cash used by operating  activities for the year ended December 31, 1999, was
$3,442,000  compared with net cash provided by operating  activities of $574,000
for the  comparable  1998  period.  Net cash used by  operating  activities  was
primarily  attributable  to the  increase  in trade  receivables,  a decrease in
accounts  payable and accrued  expenses  and by the net loss for the 1999 period
offset by a decrease in inventories.

Net cash used by investing  activities for the year ended December 31, 1999, was
$1,822,000  compared with net cash used by investing  activities of $591,000 for
the prior  comparable  1998 period.  The net cash usage  primarily  consisted of
equipment  additions  primarily  associated  with the expansion of the Company's
depot network.

Net cash provided by financing  activities for the year ended December 31, 1999,
was $6,971,000  compared with net cash used by financing  activities of $167,000
for the comparable  1998 period.  The net cash provided by financing  activities
primarily  consisted  of  proceeds  from  the  sale of the  Company's  Series  A
Preferred  Stock and net  proceeds  from  long and short  term debt for the 1999
period.

At December 31, 1999, the Company had cash and equivalents of $2,483,000.

During 1996,  the Company  mortgaged  its  property and building  located in Ft.
Lauderdale  with  Turnberry  Savings  Bank,  NA. The  mortgage of  $660,000,  at
December 31, 1999, bears interest rate of 9.5% and is repayable over 20 years


                                       13

through January 2017. The Company has principally  ceased its operations at this
facility and has entered  into a three year lease of the entire  facility at the
current level of $13,125 per month to an unaffiliated  third party.  The Company
intends to sell this property in the foreseeable future.

During January 1997, in connection with the execution of various agreements with
E.I. DuPont de Nemours ("DuPont'),  the Company obtained additional equity funds
of $3,500,000 from an affiliate of DuPont.  The proceeds were primarily utilized
to retire debt.

On April 28, 1998,  the Company  entered into a credit  facility  with CIT which
made  available  borrowings  to the  Company  of up to  $5,000,000.  The  credit
facility was  increased to  $6,500,000 in 1999.  The facility  requires  minimum
borrowings of $1,250,000.  The facility  provides for a revolving line of credit
and a six-year term loan and expires in April 2001. Advances under the revolving
line of credit are limited to (i) 80% of eligible trade accounts  receivable and
(ii) 50% of eligible  inventory (which inventory amount shall not exceed 200% of
eligible trade accounts receivable or $3,250,000).  As of December 31, 1999, the
Company had  availability  under its revolving  line of credit of  approximately
$700,000.  Advances  available  to the Company  under the term loan are based on
existing fixed asset valuations and future advances under the term loan up to an
additional $1,000,000 are based on future capital expenditures. During 1999, the
Company  received  advances of  $166,000  based on capital  expenditures.  As of
December 31, 1999, the Company has approximately  $861,000 outstanding under its
term loans.  As of December 31,  1999,  the Company had  $1,500,000  outstanding
under its revolving  line of credit.  The facility  bears  interest at the prime
rate plus 1.5%, 10% at December 31, 1999, and substantially all of the Company's
assets are pledged as  collateral  for  obligations  to CIT. In addition,  among
other things,  the agreements  restrict the Company's  ability to declare or pay
any dividends on its capital  stock.  The Company has obtained a waiver from CIT
to permit the payment of dividends on its Series A Preferred Stock.

In connection  with the loan  agreements,  the Company issued to CIT warrants to
purchase 30,000 shares of the Company's  common stock at an exercise price equal
to 110% of the  then  fair  market  value  of the  stock,  which  on the date of
issuance  was $4.33 per share,  and  expires  April 29,  2001.  The value of the
warrants were not deemed to be material.

Effective  March 19, 1999, the Company sold 75% of its stock ownership in ESS to
one of ESS's founders.  The consideration for the Company's sale of its interest
was  $100,000 in cash and a six year 6% interest  bearing  note in the amount of
$380,000.  The Company  will  recognize  as income the  portion of the  proceeds
associated with the net receivables  upon the receipt of cash. This sale did not
have a  material  effect on the  Company's  financial  condition  or  results of
operation.  It is not  anticipated  that the  Company  will be  involved  in, or
control,  the operations of ESS. Effective October 11, 1999, the Company sold to
three of ESS's  employees  an  additional  5.4%  ownership  in ESS.  The Company
received $37,940 from the sale of this additional ESS stock.

The Company is continuing to evaluate  opportunities  to  rationalize  its other
operating  facilities  based on its  emphasis  on the  expansion  of its service
sales. As a result,  the Company may  discontinue  certain  operations  which it
believes do not support the growth of service  sales and, in doing so, may incur
future charges to exit certain operations.

On March 30, 1999, the Company completed the sale of 65,000 shares of its Series
A Preferred  Stock,  with a liquidation  value of $100 per share,  to Fleming US
Discovery  Fund III,  L.P. and Fleming US Discovery  Offshore Fund III, L.P. The
gross proceeds from the sale of the Series A Preferred Stock is $6,500,000.  The
Series A Preferred  Stock has voting  rights on an as-if  converted  basis.  The
number  of votes  applicable  to the  Series A  Preferred  Stock is equal to the
number of shares of Common Stock into which the Series A Preferred Stock is then
convertible.  However,  the holders of the Series A Preferred Stock will provide
the Chief  Executive  Officer and  Secretary  of the Company a proxy to vote all
shares currently owned and subsequently acquired above 29% of the votes entitled
to be cast by all  shareholders  of the Company.  The Preferred  Stock carries a
dividend  rate  of 7%,  which  will  increase  to  16%,  if the  stock  remained
outstanding,  on the fifth  anniversary  date, and converts to Common Stock at a
rate of $2.375 per share, which was 27% above the closing market price of Common
Stock  on  March  29,  1999.  The  conversion  rate may be  subject  to  certain
antidilution provisions. The Company is using the net proceeds from the issuance
of the Series A Preferred Stock to expand its  RefrigerantSide(TM)  Services and
for working capital purposes.

The Company will pay  dividends,  in arrears,  on the Series A Preferred  Stock,
semi annually,  either in cash or additional  shares,  at the Company's  option,
during the first two years after which the  dividends  will be paid in cash.  On
September 30, 1999,  the Company  declared and paid,  in-kind,  the dividends of
outstanding on the Series A Preferred Stock. The Company issued a total of 2,314
additional  shares  of its  Series  A  Preferred  Stock in  satisfaction  of the
dividends due. The Company may redeem the Series A Preferred  Stock on March 31,
2004  either  in cash or shares of  Common  Stock  valued at 90% of the  average
trading price of the Common Stock for the 30 days  preceding  March 31, 2004. In
addition,  after  March 30,  2001,  the  Company may call the Series A Preferred
Stock if the market price of its Common Stock is


                                       14
<PAGE>


equal or greater  than 250% of the  conversion  price and the  Common  Stock has
traded with an average  daily volume in excess of 20,000  shares for a period of
thirty consecutive days.

The Company has provided certain  registration,  preemptive and tag along rights
to the  holders of the Series A  Preferred  Stock.  The  holders of the Series A
Preferred Stock,  voting as a separate class,  have the right to elect up to two
members to the Company's Board of Directors or at their option,  to designate up
to two advisors to the  Company's  Board of Directors who will have the right to
attend and observe  meetings of the Board of Directors.  Currently,  the holders
have elected two members to the Board of Directors.

The Company engaged an advisor to facilitate the Company's efforts in connection
with the sale of its Series A Preferred  Stock. In addition to the advisor fees,
the Company  issued to the advisor,  warrants to purchase  136,482 shares of the
Company's  Common  Stock at an  exercise  price per share of $2.73.  The Company
incurred  an  aggregate  of $700,000  in costs  associated  with the sale of the
Series A Preferred Stock and such costs have been charged to additional  paid-in
capital.

The Company believes that its anticipated  cash flow from  operations,  together
with the proceeds from the sale of its Preferred Stock, and its credit facility,
will be sufficient to satisfy the Company's  working  capital  requirements  and
proposed  expansion  of its service  business  for the next twelve  months.  Any
additional  expansion or acquisition  opportunities that may arise in the future
may  affect  the  Company's  future  capital  needs.  However,  there  can be no
assurances  that the  Company's  proposed  or  future  expansion  plans  will be
successful, and as such, the Company may have future capital needs.

Acquisitions

In April 1996, the Company acquired all the outstanding  capital stock of ESS, a
developer  and provider of  environmental  software,  training,  and  management
services in  consideration  of  $2,375,000,  consisting  of cash of $700,000 and
promissory  notes in the principal amount of $1,675,000 which were repaid during
October 1996. The  acquisition  was accounted for as a purchase from the date of
acquisition  with the assets acquired and liabilities  assumed  recorded at fair
values,  resulting  in an excess of cost over assets  acquired of  approximately
$800,000.

In June 1996,  ESS  acquired  all the net  assets,  subject to  liabilities,  of
E-Soft, Inc.  ("E-Soft"),  a developer and marketer of software programs related
to hazardous material management,  in consideration of a cash payment of $50,000
and 41,560  shares of common  stock  with the  acquired  assets and  liabilities
assumed  recorded  at fair  values,  resulting  in an excess of cost over assets
acquired of approximately $500,000.

Effective  March 19, 1999, the Company sold 75% of its stock ownership in ESS to
one of its founders.  The  consideration  for the Company's sale of its interest
was $100,000 in cash and a six year note in the amount of $380,000.  The Company
will recognize,  as income, the portion of the proceeds associated with the note
receivable upon the receipt of cash.  This sale did not have a material  adverse
effect on the Company's  financial position or results of operations.  It is not
anticipated  that the Company will be involved in or control the  operations  of
ESS.  Effective October 11, 1999, the Company sold to three of ESS' employees an
additional 5.4% ownership in ESS. The Company  received $37,940 from the sale of
the additional ESS stock.

Inflation

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

Reliance on Suppliers and Customers

The  Company's  financial  performance  is in part  dependent  on its ability to
obtain  sufficient  quantities  of  virgin  and  reclaimable  refrigerants  from
manufacturers,  wholesalers,  distributors,  bulk gas  brokers,  and from  other
sources within the air conditioning and refrigeration and automotive aftermarket
industries, and on corresponding demand for refrigerants. To the extent that the
Company is unable to obtain sufficient quantities of refrigerants in the future,
or resell reclaimed  refrigerants at a profit, the Company's financial condition
and results of operations would be materially adversely affected.  The loss of a
principal customer would have a material adverse effect on the Company.

During January 1997, the Company  entered into  agreements with DuPont to market
DuPont's SUVA(TM) refrigerants. Under the agreement, 100% of virgin refrigerants
provided to specified  market  segment  customers  must be purchased from DuPont
(see "Description of Business - Strategic Alliance").


                                       15
<PAGE>


During the year ended December 31, 1999, one customer accounted for an aggregate
of 17% of the Company's  revenues.  During the year ended December 31, 1998, two
customers accounted for an aggregate of 42% of the Company's revenues.  The loss
of a principal  customer or a decline in the economic prospects and purchases of
the Company's  products or services by any such  customer,  as incurred in 1999,
would have a material  adverse  effect on the Company's  financial  position and
results of operations.

Seasonality and Fluctuations in Operating Results

The  Company's  operating  results  vary  from  period  to period as a result of
weather   conditions,   requirements  of  potential   customers,   non-recurring
refrigerant and service sales,  availability  and price of refrigerant  products
(virgin or  reclaimable),  changes in reclamation  technology  and  regulations,
timing in introduction and/or retrofit or replacement of CFC-based refrigeration
equipment  by  domestic  users of  refrigerants,  the rate of  expansion  of the
Company's  operations,   and  by  other  factors.  The  Company's  business  has
historically  been seasonal in nature with peak sales of refrigerants  occurring
in the first half of each year. Accordingly, the second half of the year results
of operations  have reflected  additional  losses due to a decrease in revenues.
Delays in securing  adequate  supplies of  refrigerants  at peak demand periods,
lack of refrigerant demand, increased expenses, declining refrigerant prices and
a loss of a principal customer could result in significant losses.  There can be
no assurance that the foregoing  factors will not occur and result in a material
adverse effect on the Company's financial position and significant losses.

Recent Accounting Pronouncements

The Company  adopted  SFAS No. 133 as of January 1, 1999.  The  adoption did not
have a  material  effect on the  Company's  financial  position  or  results  of
operations.

Compliance with Section 16(a) of the Securities Exchange Act

     Section 16(a) of the Securities Exchange Act of 1934 requires the Company's
officers and directors, and persons who own more than 10 percent of a registered
class of the  Company's  equity  securities,  to file reports of  ownership  and

Officers,  directors,  and greater than 10 percent  stockholders are required by
SEC  regulation  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,
1999 all filing requirements applicable to its officers,  directors, and greater
than 10 percent  beneficial  stockholders  were  complied  with  except that (i)
Messrs Burr and Zech failed to timely file a Form 3 upon  becoming  directors of
the Company, (ii) Messrs. Kevin Zugibe,  Thomas P. Zugibe,  Stephen Mandracchia,
Brian Coleman and Walter  Philips failed to timely file a Form 4 with respect to

successive  terms.  Pursuant to the agreement,  effective  February 1, 2000, Mr.
Zugibe is  receiving an annual base salary of $70,000  with such  increases  and
bonuses  as the  Board  may  determine.  The  Company  is the  beneficiary  of a

$1,000,000.

The Company has entered into a three-year  employment  contract with Mr. Coleman

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  Securities  Exchange
Act of 1934, as amended (the "Exchange  Act") and is administered by a committee
of the Board of  Directors,  which  currently  consists  of Messrs.  Abbatecola,
Morch,  Burr 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
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.


                                       21
<PAGE>


As of December 31, 1999, options to purchase 248,266 shares of Common Stock were
issued under the Plan.  During  1999,  the Company  granted  options to purchase
70,000 shares to employees,  exercisable  at prices  ranging from $1.94 to $2.50
per share (see Note 11 to the Notes to the Consolidated Financial Statements).

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  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 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 and Morch. 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 85% of the market  value of the Common Stock on the date of
grant.  Options  granted under the 1997 Plan will expire not more than ten years

Report of Independent Certified Accountants

To Stockholders and Board of Directors

Hudson Technologies, Inc.
Pearl River, New York

     We have  audited  the  accompanying  consolidated  balance  sheet of Hudson
Technologies,  Inc.  and  subsidiaries  as of December  31, 1999 and the related
consolidated  statements of operations,  stockholders' equity and cash flows for
each of the two years in the period ended  December 31,  1999.  These  financial
statements   are  the   responsibility   of  the   Company's   management.   Our
responsibility  is  to  express  an  opinion  on  these  consolidated  financial
statements based on our audits.

     We conducted  our audits in accordance  with  generally  accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable  assurance  about  whether  the  financial  statements  are free from
material  misstatement.  An audit includes examining,  on a test basis, evidence
supporting  the amounts and  disclosures in the financial  statements.  An audit
also includes assessing the accounting principles used and significant estimates
made by  management,  as well as  evaluating  the  overall  financial  statement
presentation.  We believe  that our audits  provide a  reasonable  basis for our
opinion.

     In our opinion,  the consolidated  financial  statements  referred to above
present  fairly,  in all material  respects,  the  financial  position of Hudson
Technologies,  Inc. and subsidiaries as of December 31, 1999, and the results of
their  operations  and their  cash flows for each of the two years in the period
ended  December  31,  1999 in  conformity  with  generally  accepted  accounting
principles.

                   Hudson Technologies, Inc. and subsidiaries
                 Notes to the Consolidated Financial Statements

Note 1- Summary of Significant Accounting Policies

Business

Hudson  Technologies,  Inc.,  incorporated under the laws of New York on January
11,  1991,  together  with  its  subsidiaries  (collectively,  "Hudson"  or  the
"Company"),   primarily  sells  refrigerants  and  provides  RefrigerantSide(TM)
Services performed at a customer's site, consisting of system decontamination to
remove moisture and oils and other  contaminants and recovery and reclamation of
the refrigerants used in commercial air conditioning and refrigeration  systems.
The Company  operates as a single  segment  through its wholly owned  subsidiary
Hudson Technologies Company.

Consolidation

The consolidated  financial  statements  represent all companies of which Hudson
directly or indirectly has majority ownership or otherwise controls. Significant
intercompany  accounts and  transactions  have been  eliminated.  The  Company's
consolidated   financial   statements   include  the  accounts  of  wholly-owned
subsidiaries Hudson Holdings,  Inc. and Hudson Technologies  Company.  Effective
March 19, 1999, the Company sold 75% of its ownership  interest in Environmental
Support  Solutions,  Inc.  ("ESS") and as of that date,  no longer  includes the
results of that operation in the consolidated results of the Company.  Effective
October 11, 1999, the Company sold an additional 5.4% ownership interest in ESS.

Fair value of financial instruments

The  carrying   values  of  financial   instruments   including  trade  accounts
receivable,  and accounts  payable  approximate fair value at December 31, 1999,
because of the  relatively  short  maturity of these  instruments.  The carrying
value of short-and  long-term debt  approximates  fair value,  based upon quoted
market rates of similar debt issues, as of December 31, 1999.

Credit risk

Financial  instruments,  which potentially subject the Company to concentrations
of credit risk,  consist  principally  of temporary cash  investments  and trade
accounts  receivable.  The Company  maintains its temporary cash  investments in
highly-rated  financial  institutions.  The Company's trade accounts receivables
are due from companies  throughout the U.S. The Company  reviews each customer's
credit history before extending credit.

The Company  establishes  an allowance  for doubtful  accounts  based on factors
associated with the credit risk of specific  accounts,  historical  trends,  and
other information.

During the year ended  December 31,  1999,  one  customer  accounted  for 17% of
revenues.  During the year ended December 31, 1998, one customer,  an affiliate,
accounted  for 28%  and  another  customer  accounted  for  14%.  The  loss of a
principal  customer or a decline in the economic  prospects and purchases of the
Company's products or services by any such customer,  as incurred in 1999, would
have an  adverse  effect on the  Company's  financial  position  and  results of
operations.

Cash and cash equivalents

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

Inventories

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


                                       33
<PAGE>


Property, plant, and equipment

Property,  plant,  and  equipment  are  stated  at  cost;  including  internally
manufactured   equipment.   The  cost  to  complete   equipment  that  is  under
construction  is  not  considered  to be  material  to the  Company's  financial
position.  Provision  for  depreciation  is recorded  (for  financial  reporting
purposes) using the straight-line method over the useful lives of the respective
assets.  Leasehold  improvements are amortized on a straight-line basis over the
shorter of economic life or terms of the respective leases.

Due to the specialized nature of the Company's business, it is possible that the
Company's estimates of equipment useful life periods may change in the future.

Revenues and cost of sales

Revenues are recorded upon completion of service or product  shipment or passage
of title to customers in accordance  with  contractual  terms.  Cost of sales is
recorded based on the cost of products shipped or services performed and related
direct operating costs of the Company's facilities.

Income taxes

The Company  utilizes the assets and  liability  method for  recording  deferred
income  taxes,  which  provides for the  establishment  of deferred tax asset or
liability accounts based on the difference  between tax and financial  reporting
bases of certain assets and liabilities.

The Company  recognized a reserve allowance against the deferred tax benefit for
the  current  and prior  period  losses.  The tax  benefit  associated  with the
Company's net operating  loss carry  forwards  would be recognized to the extent
that the Company recognized net income in future periods.

Loss per common and equivalent shares

Loss per common share (Basic) is calculated based on the net loss for the period
less dividends on the outstanding Series A Preferred Stock, $349,000 for 1999 of
which  $231,000 was paid in kind on September 30, 1999,  divided by the weighted
average number of shares  outstanding.  If dilutive,  common  equivalent  shares
(common  shares  assuming  exercise of options and  warrants  or  conversion  of
Preferred  Stock)  utilizing  the treasury  stock method are  considered  in the
presentation  of dilutive  earnings  per share.  Diluted  loss per share was not
presented since the effect was not dilutive.

Estimates and Risks

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

The Company  participates  in an industry that is highly  regulated,  changes in
which could affect operating results. Currently the Company purchases virgin and
reclaimable  refrigerants  from  domestic  suppliers and its  customers.  To the
extent  that the  Company  is  unable  to obtain  refrigerants  on  commercially
reasonable  terms or  experiences  a decline  in demand  for  refrigerants,  the
Company could realize reductions in refrigerant  processing and possible loss of
revenues, which would have a material adverse affect on operating results.

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

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

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


                                       34
<PAGE>


carrying amount of the assets exceeds the fair value of the assets. Assets to be
disposed of are reported at the lower of the carrying  amount or fair value less
the cost to sell.

Recent accounting pronouncements

The Company  adopted  SFAS No. 133 as of January 1, 1999.  SFAS No. 133 requires
that an entity  recognize  derivatives  as either assets or  liabilities  in the
statement of financial position and measure those instruments at fair value. The
adoption did not have a material effect on the Company's  financial  position or
results of operations.

Note 2 - Acquisitions

On April 23, 1996,  the Company  acquired all the  outstanding  capital stock of
ESS,  a  developer  and  provider  of  environmental  software,   training,  and
management  services  in  consideration  of  $2,375,000,  consisting  of cash of
$700,000 and  promissory  notes of $1,675,000  which were repaid during  October
1996.  The  acquisition  was  accounted  for as a  purchase  from  the  date  of
acquisition  with the assets acquired and liabilities  assumed  recorded at fair
values,  resulting  in an excess of cost over assets  acquired of  approximately
$800,000.   Results  of  ESS's   operations   were  included  in  the  Company's
consolidated financial statements from the date of acquisition.

On June 14, 1996, ESS acquired all the net assets,  subject to  liabilities,  of
E-Soft, Inc.  ("E-Soft"),  a developer and marketer of software programs related
to hazardous material management,  in consideration of a cash payment of $50,000
and 41,560  unregistered  shares of the Company's stock.  E-Soft acquired assets
and  liabilities  were  recorded at fair values,  resulting in an excess of cost
over assets acquired of approximately  $500,000.  Subsequent to the acquisition,
all E-Soft assets and activities were relocated to ESS headquarters in Arizona.

Effective  March 19, 1999, the Company sold 75% of its stock ownership in ESS to
one of its founders.  The  consideration  for the Company's sale of its interest
was $100,000 in cash and a six year note in the amount of $380,000.  The Company
recognized a valuation  allowance for 100% of the note  receivable.  The Company
will  recognize as income the portion of the proceeds  associated  with the note
receivable upon the receipt of cash. This sale did not have a material effect on
the  Company's  financial  condition  or  results  of  operations.   It  is  not
anticipated  that the Company will be involved in or control the  operations  of
ESS.  Effective October 11, 1999, the Company sold to three of ESS' employees an
additional 5.4% ownership in ESS. The Company  received $37,940 from the sale of
the additional ESS stock.

Note 3 - Other income

For the year ended  December  31, 1999,  and 1998,  other income of $106,000 and
$132,000,  respectively,  consisted  mainly  of  lease  rental  income  from the
Company's Ft. Lauderdale facility.

Note 4 - Income taxes

During the years  ended  December  31,  1999 and 1998,  there were no income tax
expense recognized due to the Company's net losses.

Reconciliation  of the Company's actual tax rate to the U.S.  Federal  statutory
rate is as follows:

("NOL's") of  approximately  $20,000,000  expiring 2007 through 2014 for which a
100%  valuation   allowance  has  been   recognized.   Refrigerant   Reclamation
Corporation  of America  ("RRCA"),  acquired  during 1995 as a subsidiary of the

Bank credit line

On  April  28,  1998,  the  Company  entered  into a  credit  facility  with CIT
Group/Credit Finance Group, Inc. ("CIT") which makes available borrowings to the
Company of up to $5,000,000  and  increased to $6,500,000 in 1999.  The facility
requires minimum borrowings of $1,250,000. The facility provides for a revolving
line of credit and a six-year  term loan and  expires  in April  2001.  Advances
under the  revolving  line of credit are  limited to (i) 80% of  eligible  trade
accounts  receivable and (ii) 50% of eligible  inventory (which inventory amount
shall not exceed 200% of eligible trade accounts  receivable or $3,250,000).  As
of December 31, 1999, the Company has  availability  under its revolving line of
credit of approximately $700,000.  Advances, available to the Company, under the
term loan are based on existing fixed asset valuations and future advances under
the  term  loan up to an  additional  $1,000,000  are  based on  future  capital
expenditures.  During 1999, the Company  received  advances of $166,000 based on
capital  expenditures.  As of December 31, 1999,  the Company has  approximately
$861,000  outstanding under its term loans. As of December 31, 1999, the Company
had  $1,500,000  outstanding  under its revolving  line of credit.  The facility
bears  interest  at the prime rate plus 1.5%,  10% at  December  31,  1999,  and
substantially  all of  the  Company's  assets  are  pledged  as  collateral  for
obligations to CIT. In addition, among other things, the agreements restrict the
Company's  ability to declare or pay any  dividends  on its capital  stock.  The
Company has obtained a waiver from CIT to permit the payment of dividends on its
Series A Preferred Stock.

Mortgage payable

During 1996,  the Company  mortgaged  its  property and building  located in Ft.
Lauderdale  with  Turnberry  Savings  Bank,  NA. The  mortgage of  $660,000,  at
December 31, 1999 bears  interest at a rate of 9.5% and repayable  over 20 years
through January 2017.

Vehicle Loans

During 1999, the Company  entered into various  vehicle loans.  The vehicles are
primarily used in connection with the Company's on-site services.  The loans are
payable in 60 monthly  payments  through  October 2004 and bear interest at 9.0%
through 9.98%.

RRCA Priority Claims

In connection  with its  bankruptcy  reorganization  in June 1994,  prior to its
acquisition  by  Hudson,  RRCA  had  unsecured  obligations,  as  modified  by a
settlement  during  April  1996,  payable in  periodic  payments  to  bankruptcy
creditors through January 2000.

Note 9 - Stockholders' equity

On May 10, 1996, the Board of Directors authorized the Company to acquire,  from
publicly  traded markets,  a maximum of 25,000 issued and outstanding  shares of
its own Common Stock. In 1996, the Company had  repurchased  21,000 shares at an
average price of $8.25 per share. No shares were subsequently purchased.  During
1998, the Company retired the 21,000 shares of stock held in treasury.

In September  1996 and October  1997, in  connection  with the then  outstanding
convertible debentures,  the Company issued warrants to purchase an aggregate of
16,071 and 66,000 shares of the Company's  Common Stock at an exercise  price of
$18.00 and $10.00, respectively, per share. These warrants expire through August
6, 2002.

On January 29, 1997, the Company  entered into a Stock  Purchase  Agreement with
DuPont and DuPont  Chemical and Energy  Operations,  Inc.  ("DCEO")  pursuant to
which the Company issued to DCEO 500,000 shares of Common Stock in consideration
of $3,500,000  in cash.  Simultaneous  with the execution of the Stock  Purchase
Agreement,  the  parties  entered  into a  Standstill  Agreement,  Shareholders'
Agreement and Registration Agreement.

The Standstill Agreement provides,  subject to certain exceptions,  that neither
DuPont nor any  corporation  or entity  controlled  by DuPont will,  directly or
indirectly,  acquire any shares of any class of capital  stock of the Company if
the effect of such acquisition  would be to increase  DuPont's  aggregate voting
power to greater than 20% of the total  combined  voting  power  relating to any
election of directors.  The Standstill  Agreement also provides that the Company
will  cause two  persons  designated  by DCEO and  DuPont to be  elected  to the
Company's Board of Directors.

The Shareholders' Agreement provides that, subject to certain exceptions, DuPont
shall have a right of first  refusal  to  purchase  any  shares of Common  Stock
intended to be sold by the Company's principal shareholders.


                                       38

Pursuant to the  Registration  Agreement,  the Company granted to DuPont certain
demand and "piggy-back" registration rights.

During 1998, the Company issued, to a vendor,  20,000 shares of common stock for
services  rendered  during the year.  The value of the services  was  recognized
based on the fair value of the stock at the time of issuance.

On April 28, 1998, in connection  with the loan agreements with CIT, the Company
issued to CIT warrants to purchase  30,000 shares of the Company's  common stock
at an exercise  price equal to 110% of the then fair market  value of the stock,
which on the date of issuance  was $4.33 per share and expires  April 29,  2001.
The value of the warrants were not deemed to be material and expire on April 29,
2001. In addition,  among other things,  the  agreements  restrict the Company's
ability to declare or pay any  dividends on its capital  stock.  The Company has
obtained a waiver  from CIT to permit the payment of  dividends  on its Series A
Preferred Stock.

On March 16, 1999, the  shareholders of the Company approved an amendment to the
Certificate of  Incorporation  to authorize the issuance of 5,000,000  shares of
Preferred  Stock.  This  authorization  allows the Board of Directors  to, among
other things,  set the number of shares, the dividend rate and the voting rights
on any issuance of Preferred Stock.

On March 30, 1999, the Company completed the sale of 65,000 shares of its Series
A Preferred  Stock,  with a liquidation  value of $100 per share,  to Fleming US
Discovery  Fund III,  L.P. and Fleming US Discovery  Offshore Fund III, L.P. The
gross proceeds from the sale of the Series A Preferred Stock is $6,500,000.  The
Series A Preferred  Stock has voting  rights on an as-if  converted  basis.  The
number  of votes  applicable  to the  Series A  Preferred  Stock is equal to the
number of shares of Common Stock into which the Series A Preferred Stock is then
convertible.  However,  the holders of the Series A Preferred Stock will provide
the Chief  Executive  Officer and  Secretary  of the Company a proxy to vote all
shares currently owned and subsequently acquired above 29% of the votes entitled
to be cast by all  shareholders  of the Company.  The Preferred  Stock carries a
dividend  rate  of 7%,  which  will  increase  to  16%,  if the  stock  remained
outstanding,  on the fifth  anniversary  date, and converts to Common Stock at a
rate of $2.375 per share, which was 27% above the closing market price of Common
Stock  on  March  29,  1999.  The  conversion  rate may be  subject  to  certain
antidilution provisions. The Company is using the net proceeds from the issuance
of the Series A Preferred Stock to expand its  RefrigerantSide(TM)  Services and
for working capital purposes.

The Company will pay  dividends,  in arrears,  on the Series A Preferred  Stock,
semi annually,  either in cash or additional  shares,  at the Company's  option,
during the first two years after which the  dividends  will be paid in cash.  On
September 30, 1999,  the Company  declared and paid,  in-kind,  the dividends of
outstanding on the Series A Preferred Stock. The Company issued a total of 2,314
additional  shares  of its  Series  A  Preferred  Stock in  satisfaction  of the
dividends due. The Company may redeem the Series A Preferred  Stock on March 31,
2004  either  in cash or shares of  Common  Stock  valued at 90% of the  average
trading price of the Common Stock for the 30 days  preceding  March 31, 2004. In
addition,  after  March 30,  2001,  the  Company may call the Series A Preferred
Stock if the market  price of the Common  Stock is equal or greater than 250% of
the  conversion  price and the  Common  Stock has traded  with an average  daily
volume in excess of 20,000 shares for a period of thirty consecutive days.

The Company has provided certain  registration,  preemptive and tag along rights
to the  holders of the Series A  Preferred  Stock.  The  holders of the Series A
Preferred Stock,  voting as a separate class,  have the right to elect up to two
members to the Company's Board of Directors or at their option,  to designate up
to two advisors to the  Company's  Board of Directors who will have the right to
attend and observe  meetings of the Board of Directors.  Currently,  the holders
have elected two members to the Board of Directors.

The Company engaged an advisor to facilitate the Company's efforts in connection
with the sale of the Series A Preferred  Stock. In addition to the advisor fees,
the Company  issued to the advisor,  warrants to purchase  136,482 shares of the
Company's  Common  Stock at an  exercise  price per share of $2.73.  The Company
incurred  an  aggregate  of $700,000  in costs  associated  with the sale of the
Series A Preferred Stock and such costs have been charged to additional  paid-in
capital.

Legal Proceedings

During  June 1995,  United  Water of New York Inc.  ("United")  alleged  that it
discovered  that  two of its  wells  within  close  proximity  to the  Company's
Hillburn, New York facility showed elevated levels of refrigerant contamination,
specifically Trichlorofluoromethane (R-11). During December 1997, United alleged
that it discovered levels of Dichlorodifluoromethane  (R-12) in two of its wells
within  close  proximity  to the  Company's  facility,  and has alleged that the
Company is the  source.  Sampling  by the  Company of various  monitoring  wells
installed  around the  Company's  facilities  have been taken on a monthly basis
since August 1996 and have detected levels of R-11 in the groundwater,  but have
failed to  detect  any  levels  of R-12 in the  groundwater  in and  around  the
Company's facility.

In January  1998,  the  Company  agreed to install a  remediation  system at the
Company's  facility to remove any remaining R-11 levels in the groundwater under
and around the Company's facility. In August 1998, the New York State Department
of  Environmental  Conservation  ("DEC")  accepted  the  Company's  proposal and
requested that the Company proceed with the installation of the system. The cost
of this remediation system was $100,000.

In June 1998,  United  commenced  an action  against  the Company in the Supreme
Court of the State of New York,  Rockland County,  seeking damages in the amount
of $1.2  million  allegedly  sustained  as a  result  of the  foregoing  alleged
contamination.  In December 1998, United served an amended complaint asserting a
claim  pursuant to the Resource  Conservation  and Recovery  Act, 42 U.S.C.  ss.
6901,  et. seq.  ("RCRA") In January 1999, the Company filed a motion to dismiss
the RCRA cause of action.

On April 1, 1999, the Company reported a release at the Company's Hillburn,  New
York facility of what was ultimately  determined to be approximately  7,800 lbs.
of R-11, as a result of a failed hose connection to one of the Company's outdoor
storage tanks allowing  liquid R-11 to discharge from the tank into the concrete
secondary  containment area in which the subject tank was located.  An amount of
the R-11 escaped the secondary  containment  area through an open drain from the
secondary  containment area for removing  accumulated  rainwater and entered the
ground.  The  Company  immediately  commenced  excavation  operations  to remove
contaminated soil and has taken a number of other steps to mitigate and minimize
contamination,  including  acceleration  of  the  installation  of  the  planned
remediation system.

In April 1999,  the  Company was advised by United that one of its wells  within
close  proximity to the Company's  facility  showed  elevated  levels of R-11 in
excess of 200 ppb. and was taking certain steps and would be incurring  costs in
an attempt to  remediate  any  contamination.  In response to the  release,  the
Company requested,  and in May 1999, received permission from the DEC to operate
the planned remediation system pending negotiation and finalization of a Consent
Order covering the operation of the system.  The remediation system was put into
operation  on May 7, 1999.  The level of R-11 in the  affected  United well have
steadily  decreased  since June 1, after rising to a level in excess of 700 ppb.
and on March 13, 2000 was reduced to 5.5 ppb. In December  1999, a second United
well within close  proximity to the Company's  facility  began showing  elevated
levels  of  R-11 in  excess  of 5 ppb.  and  increased  to a high of 26 ppb.  in
February 2000. The Company  continues to work with the DEC,  United and with the
Company's  experts to determine the scope of any  contamination,  and to develop
plans for the  construction of a separate  remediation  system to directly treat
contaminated water from United's well.

In July 1999, United filed a motion seeking permission to amend its complaint in
the action it commenced  in June 1998 to allege  facts  relating to, and to seek
damages allegedly  resulting from the April 1, 1999 release. In August 1999, the
Company entered into a stipulation  accepting  service of the amended  complaint
subject to the Company's pending


                                       41

motion to dismiss. On August 26, 1999, the Court issued a decision which granted
the Company's  motion to dismiss that portion of United's RCRA claims which seek
past cleanup  costs,  and held in abeyance a ruling  whether United can assert a
claim for present/future cleanup under RCRA until the date of trial. The Company
continues to defend the claims asserted by United.

The Company carries $1,000,000 of pollution  liability  insurance per occurrence
and has put the insurance  carrier on notice of the release and possible  claims
of  United.  There can be no  assurance  that  this  action,  or any  settlement
thereof,  will be resolved in a manner  favorable  to the  Company,  or that the
ultimate outcome of any legal action or settlement,  or the effects of the April
1, 1999  release,  will not have a  material  adverse  effect  on the  Company's
financial condition and results of operations.

During March and April 1998,  six (6)  complaints,  each alleging  violations of
Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, were filed by a
total of eight  shareholders,  on behalf of themselves and all others  similarly
situated,  against the Company and certain of its officers and  directors in the
United States District Court for the Southern  District of New York. Each of the
complaints  alleged  that the  defendants,  among other  things,  misrepresented
material  information about the Company's  financial results and prospects,  and
its customer relationships.  In October 1998, a consolidated complaint on behalf
of the  plaintiffs  was served upon the Company.  In December 1998, a motion was
made on behalf of the Company to dismiss each of the claims asserted against the
Company in the consolidated  complaint.  On September 26, 1999, the Court issued
an opinion and order dismissing with prejudice three of the five claims asserted
by the  plaintiffs  and further  dismissing  the  remaining  two claims  without
prejudice  to the  plaintiffs  filing a second  amended  consolidated  complaint
within  thirty  (30) days of the date of the  Court's  opinion  and  order.  The
plaintiffs  failed to serve a second amended  consolidated  complaint,  and as a
result,  in  November  1999,  a  final  judgment  was  entered   dismissing  the
consolidated complaint in its entirety.

In June 1999,  an action  was  commenced  in the Baton  Rouge  Supreme  Court by
William Freeman and three others against the Company seeking unspecified damages
for  alleged  personal  injuries  allegedly  suffered  as a result of an ammonia
release at the  Company's  Louisiana  facility  in  January  1999.  The  Company
maintains  that the  allegations  in the complaint are without merit and that no
damages  were  suffered  by the  plaintiffs  in  that  action.  There  can be no
assurance  that this action,  or any settlement  thereof,  will be resolved in a
manner favorable to the Company.

The Company and its  subsidiaries  are subject to various  other  claims  and/or
lawsuits from both private and  governmental  parties  arising from the ordinary
course of business; none of which are material.

Employment agreements

The Company  has  entered  into a two-year  employment  agreement  with Kevin J.
Zugibe,  which  expires  in May  2001  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 $70,000  with such  increases  and
bonuses as the Board may determine.

The Company has entered into a five year  employment  agreement with an employee
which expires in July 2001 and is renewable for successive  two year terms.  The
agreement  provided for a minimum  annual salary of $85,000 per year and bonuses
up to $115,000 per year based on certain production volumes.

Note 11 - Stock Option Plan

Effective  October 31, 1994,  the Company  adopted an Employee Stock Option Plan
("Plan")  pursuant to which  725,000  shares of common  stock are  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, 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.  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).  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 expire not more than ten years from the
date of grant (five years in the case of ISOs granted to persons  holding 10% or
more of the voting stock of the Company).

Effective July 25, 1997, and as amended on August 19, 1999, the Company  adopted
its 1997 Employee  Stock Option Plan ("1997 Plan")  pursuant to which  2,000,000
shares of common stock are  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,  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. 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).  Non-qualified  options  granted  under  the 1997 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 1997 Plan  expire  not more than ten
years from the date of grant (five years in the case of ISOs  granted to persons
holding 10% or more of the voting stock of the Company).

All stock options have been granted to employees and  non-employees  at exercise
prices equal to or in excess of the market value on the date of the grant.

The Company applies APB Opinion 25,  `Accounting for Stock Issued to Employees',
and related Interpretations in accounting for its stock option plan by recording
as  compensation  expense the excess of the fair market  value over the exercise
price per  share as of the date of grant.  Under APB  Opinion  25,  because  the
exercise  price of the Company's  employee stock options equals the market price
of the  underlying  stock  on the date of the  grant,  no  compensation  cost is
recognized.

SFAS No. 123 requires the Company to provide pro forma information regarding net
loss and net loss per  share as if  compensation  cost for the  Company's  stock
option plan had been  determined in accordance  with the fair value based method
prescribed  in SFAS No. 123. The Company  estimates the fair value of each stock
option at the grant date by using the  Black-Scholes  option-pricing  model with
the following weighted-average assumptions used for grants since 1995.

Exhibit 10.23:

                             1997 STOCK OPTION PLAN
                                       OF
                            HUDSON TECHNOLOGIES, INC.

     1. Purpose

     Hudson Technologies, Inc. (the "Company") desires to attract and retain the
best available talent and encourage the highest level of performance in order to
continue to serve the best interests of the Company, and its shareholder(s).  By
affording key personnel the opportunity to acquire proprietary  interests in the
Company and by providing  them  incentives to put forth maximum  efforts for the
success of the business, the 1997 Stock Option Plan of Hudson Technologies, Inc.
(the  "1997  Plan")  is  expected  to  contribute  to the  attainment  of  those
objectives.

     The word  "Parent" as used  herein,  shall mean any  corporation  that owns
fifty percent or more of the voting stock of the Company.

     The word  "Subsidiary"  or  "Subsidiaries"  as used herein,  shall mean any
corporation,  fifty percent or more of the voting stock of which is owned by the
Company.

     2. Scope and Duration

     Options  under the 1997 Plan may be granted in the form of incentive  stock
options ("Incentive Options") as provided in Section 422 of the Internal Revenue
Code of 1986,  as amended (the  "Code"),  or in the form of  nonqualified  stock
options ("Non-Qualified  Options").  (Unless otherwise indicated,  references in
the 1997 Plan to "options" include Incentive Options and Non-Qualified Options.)
The maximum  aggregate  number of shares as to which options may be granted from
time to time under the 1997 Plan is 2,000,000* shares of the Common Stock of the
Company ("Common Stock"),  which shares may be, in whole or in part,  authorized
but unissued shares or shares  reacquired by the Company.  The maximum number of
shares with respect to which  options may be granted to any employee  during the
term of the 1997 Plan is 500,000. Except as otherwise provided in Paragraph 7(b)
hereof, if an option shall expire,  terminate or be surrendered for cancellation
for any reason without having been exercised in full, the shares  represented by
the option or portion thereof not so exercised shall (unless the 1997 Plan shall
have been terminated)  become  available for subsequent  option grants under the
1997 Plan. As provided in Paragraph 13, the 1997 Plan shall become  effective on
June 12, 1997, and unless  terminated  sooner pursuant to Paragraph 14, the 1997
Plan shall terminate on June 11, 2007, and no option shall be granted  hereunder
after that date.

*Increased to 2,000,000 shares by shareholder resolution made August 19,1999

     3. Administration

     The 1997  Plan  shall be  administered  by the  Board of  Directors  of the
Company, or, at their discretion, by a committee which is appointed by the Board
of Directors to perform such function  (the  "Committee").  The Committee  shall
consist  of not less than two  members of the Board of  Directors,  each of whom
shall  serve  at  the  pleasure  of  the  Board  of  Directors  and  shall  be a
"Non-Employee  Director" as defined in Rule l6b-3 under the Securities  Exchange
Act of 1934 (the "Act").  Vacancies occurring in the membership of the Committee
shall be filled by appointment by the Board of Directors.

     The Board of  Directors  or the  Committee,  as the case may be, shall have
plenary  authority in its discretion,  subject to and not inconsistent  with the
express provisions of the 1997 Plan, to grant options, to determine the purchase
price of the Common Stock covered by each option,  the term of each option,  the
persons to whom,  and the time or times at which,  options  shall be granted and
the number of shares to be  covered  by each  option;  to  designate  options as
Incentive  Options or  Non-Qualified  Options;  to interpret  the 1997 Plan;  to
prescribe, amend and rescind rules and regulations relating to the 1997 Plan; to
determine the terms and provisions of the option  agreements  (which need not be
identical)  entered into in connection  with options under the 1997 Plan; and to
make  all  other   determinations   deemed   necessary  or  advisable   for  the
administration of the 1997 Plan. The Board of Directors or the Committee, as the
case may be, may delegate to one or more of its members or to one or more agents
such administrative duties as it may deem advisable,  and the Board of Directors
or the  Committee,  as the case may be, or any  person to whom it has  delegated
duties as aforesaid may employ one or more persons to render advice with respect
to any responsibility  the Board of Directors or the Committee,  as the case may
be, or such person may have under the 1997 Plan.

     4. Eligibility; Factors to be Considered in Granting Options

     Incentive  Options  shall be limited to persons  who are  employees  of the
Company or, if  applicable,  its  Parent,  or the  Company's  present and future
Subsidiaries  and at the date of grant of any  option  are in the  employ of the
Company or its Parent or the  Company's  present  and  future  Subsidiaries.  In
determining  the  employees to whom  Incentive  Options shall be granted and the
number of shares to be covered by each Incentive Option,  the Board of Directors
or the  Committee,  as the case may be,  shall take into  account  the nature of
employees' duties,  their present and potential  contributions to the success of
the Company and such other factors as it shall deem relevant in connection  with
accomplishing the purposes of the 1997 Plan. An employee who has been granted an
option or options  under the 1997 Plan may be granted  an  additional  option or
options,  subject,  in the case of Incentive Options, to such limitations as may
be  imposed  by  the  Code  on  such  options.   Except  as  provided  below,  a
Non-Qualified  Option may be granted to any person,  including,  but not limited
to, employees,  independent agents,  consultants and attorneys, who the Board of
Directors or the Committee,  as the case may be,  believes has  contributed,  or
will contribute, to the success of the Company.

     5. Option Price

     The  purchase  price of the Common  Stock  covered by each option  shall be
determined  by the Board of Directors or the  Committee,  as the case may be. In
the case of Incentive  Options,  the purchase  price shall not be less than 100%
(110% if granted to an employee  referred to in  Paragraph  8(b)  hereof) of the
Fair Market  Value (as defined in  Paragraph  15 below) of a share of the Common
Stock on the date on which the option is granted.  In the case of  Non-Qualified
Options  the  purchase  price per share of Common  Stock  covered by each option
shall be such  price,  not less than the par value a share of Common  Stock,  as
shall be determined by the Board of Directors or the Committee,  as the case may
be. Such purchase prices shall be subject to adjustment as provided in Paragraph
12 below.  The Board of  Directors or the  Committee,  as the case may be, shall
determine  the date on which an  option is  granted;  in the  absence  of such a
determination, the date on which the Board of Directors or the Committee, as the
case may be, adopts a resolution granting an option shall be considered the date
on which such option is granted.

     6. Term of Options

     The term of each option  shall be  determined  by the Board of Directors or
the  Committee,  as the case  may be,  provided,  however,  that the term of any
option  cannot be more than 10 years from the date of grant  (five  years in the
case of an Incentive Option granted to an employee referred to in Paragraph 8(b)
hereof).  All options  granted  pursuant to the 1997 Plan are subject to earlier
termination as provided in Paragraphs 10 and 11 below.

     7. Exercise of Options

     (a)  Subject  to the  provisions  of the  1997  Plan and  unless  otherwise
provided  in the option  agreement,  options  granted  under the 1997 Plan shall
become exercisable as determined by the Board of Directors or Committee.  In its
discretion, the Board of Directors or the Committee, as the case may be, may, in
any case or cases,  prescribe  that options  granted  under the 1997 Plan become
exercisable in installments or provide that an option may be exercisable in full
immediately upon the date of its grant. The Board of Directors or the Committee,
as the case may be, may, in its sole  discretion,  also  provide  that an option
granted pursuant to the 1997 Plan shall immediately  become  exercisable in full
upon the happening of any of the  following  events;  (i) the first  purchase of
shares of Common Stock  pursuant to a tender offer or exchange offer (other than
an offer by the  Company)  for all, or any part of, the Common  Stock,  (ii) the
approval by the  shareholder(s)  of the Company of an agreement  for a merger in
which  the  Company  will  not  survive  as  an   independent,   publicly  owned
corporation, a consolidation, or a sale, exchange or other disposition of all or
substantially all of the Company's assets, (iii) with respect to an employee, on
his 65th  birthday,  or (iv) with  respect  to an  employee,  on the  employee's
involuntary  termination  from  employment,  except as  provided  in  Section 10
herein.  In the event of a question or  controversy  as to whether or not any of
the events  hereinabove  described has taken place, a determination by the Board
of  Directors or the  Committee,  as the case may be, that such event has or has
not occurred shall be conclusive  and binding upon the Company and  participants
in the 1997 Plan.

     (b) Any  option  at any time  granted  under  the 1997  Plan may  contain a
provision to the effect that the optionee (or any persons  entitled to act under
Paragraph 11 hereof) may, at any time at which Fair Market Value is in excess of
the  exercise  price and prior to  exercising  the option,  in whole or in part,
request that the Company purchase all or any portion of the option as shall then
be exercisable at a price (the "Purchase Price") equal to the difference between


                                       47
<PAGE>


(i) an amount  equal to the  option  price  multiplied  by the  number of shares
subject to that portion of the option in respect of which such request  shall be
made and (ii) an amount  equal to such number of shares  multiplied  by the fair
market value of the Company's Common Stock (within the meaning of Section 422 of
the Code and the treasury  regulations  promulgated  thereunder)  on the date of
purchase.  The Company shall have no obligation to make any purchase pursuant to
such request,  but if it elects to do so, such portion of the option as to which
the request is made shall be surrendered to the Company.  The Purchase Price for
the  portion of the option to be so  surrendered  shall be paid by the  Company,
less any  applicable  withholding  tax  obligations  imposed upon the Company by
reason  of the  purchase,  at the  election  of the  Board of  Directors  or the
Committee,  as the case may be,  either in cash or in  shares  of  Common  Stock
(valued as of the date and in the manner  provided in clause (ii) above),  or in
any  combination  of cash and Common  Stock,  which may consist,  in whole or in
part,  of shares of  authorized  but  unissued  Common Stock or shares of Common
Stock held in the Company's treasury.  No fractional share of Common Stock shall
be issued or transferred and any fractional  share shall be disregarded.  Shares
covered by that portion of any option  purchased by the Company  pursuant hereto
and  surrendered  to the  Company  shall not be  available  for the  granting of
further  options  under  the 1997  Plan.  All  determinations  to be made by the
Company  hereunder shall be made by the Board of Directors or the Committee,  as
the case may be.

     (c) An option may be exercised,  at any time or from time to time (subject,
in the case of Incentive Options,  to such restrictions as may be imposed by the
Code),  as to  any or  all  full  shares  as to  which  the  option  has  become
exercisable  until the expiration of the period set forth in Paragraph 6 hereof,
by the  delivery to the Company,  at its  principal  place of  business,  of (i)
written  notice of exercise in the form  specified  by the Board of Directors or
the  Committee,  as the case may be,  specifying  the number of shares of Common
Stock  with  respect to which the  option is being  exercised  and signed by the
person  exercising the option as provided  herein,  (ii) payment of the purchase
price;  and (iii) in the case of Non-Qualified  Options,  payment in cash of all
withholding tax obligations  imposed on the Company by reason of the exercise of
the option.  Upon  acceptance  of such notice,  receipt of payment in full,  and
receipt of payment of all withholding tax  obligations,  the Company shall cause
to be issued a certificate representing the shares of Common Stock purchased. In
the event the person  exercising the option  delivers the items specified in (i)
and (ii) of this Subsection (c), but not the item specified in (iii) hereof,  if
applicable,  the option shall still be considered  exercised upon  acceptance by
the  Company  for the full  number of shares of Common  Stock  specified  in the
notice of exercise  but the actual  number of shares  issued shall be reduced by
the smallest  number of whole shares of Common Stock which,  when  multiplied by
the  Fair  Market  Value of the  Common  Stock  as of the  date  the  option  is
exercised, is sufficient to satisfy the required amount of withholding tax.

     (d) Except as otherwise provided in subsection (b) of this Paragraph 7, the
purchase price of the shares as to which an option is exercised shall be paid in
full at the time of exercise.  Payment shall be made in cash,  which may be paid
by check or other instrument acceptable to the Company; in addition,  subject to
compliance with applicable laws and regulations and such conditions as the Board
of  Directors  or the  Committee,  as the case may be, may impose,  the Board of
Directors or the Committee, as the case may be, in its sole discretion, may on a
case-by-case  basis  elect to accept  payment  in shares of Common  Stock of the
Company which are already owned by the option holder,  valued at the Fair Market
Value  thereof  (as  defined  in  Paragraph  15 below) on the date of  exercise;
provided,  however,  that with respect to Incentive Options,  no such discretion
may be exercised unless the option agreement permits the payment of the purchase
price in that manner.

     (e) Except as provided in Paragraphs 10 and 11 below,  no option granted to
an employee may be exercised at any time by such  employee  unless such employee
is then an employee of the Company or a Subsidiary or Parent.

     8. Incentive Options

     (a) With respect to Incentive  Options  granted,  the aggregate Fair Market
Value  (determined in accordance with the provisions of Paragraph 15 at the time
the  Incentive  Option is granted) of the Common Stock or any other stock of the
Company or its current or future  Subsidiaries  with respect to which  incentive
stock options,  as defined in Section 422 of the Code, are  exercisable  for the
first time by any employee  during any calendar year (under all incentive  stock
option  plans of the Company  and its parent and  subsidiary  corporation's,  as
those terms are defined in Section 424 of the Code) shall not exceed $100,000.

     (b) No  Incentive  Option may be awarded to any  employee  who  immediately
prior to the date of the granting of such Incentive Option owns more than 10% of
the  combined  voting power of all classes of stock of the Company or any of its
Subsidiaries  unless the exercise  price under the Incentive  Option is at least
110% of the Fair  Market  Value and the option  expires  within 5 years from the
date of grant.


                                       48
<PAGE>


     (c) In the  event  of  amendments  to the  Code or  applicable  regulations
relating to Incentive Options  subsequent to the date hereof,  the provisions of
the 1997 Plan and the provisions of outstanding  option  agreements  between the
Company and any  optionee  with respect to options  issued  pursuant to the 1997
Plan shall  automatically,  and without any action on the part of any person, be
modified  to  conform  to  such  amendments,  provided,  however,  that  no such
amendment  shall  occur  without  the  express  approval  of the Company and the
optionee if the effect of such amendment were to result in the granting of a new
option pursuant to Section 424(h) of the Code or any successor provision.

     9. Transferability of Options

     Incentive  Options  granted  under the 1997 Plan shall not be  transferable
otherwise  than by will or the laws of descent and  distribution,  and Incentive
Options  may be  exercised  during  the  lifetime  of the  optionee  only by the
optionee.  Non-Qualified  Options are only transferable if such right is granted
by the  Board of  Directors,  or the  Committee,  as the  case may be,  and such
provision is contained in the option agreement with respect to the Non-Qualified
Options.  No  transfer  of an option by the  optionee  by will or by the laws of
descent and  distribution  or  otherwise  shall be effective to bind the Company
unless the Company shall have been  furnished  with written notice thereof and a
copy of the will and/or such other evidence as the Company may deem necessary to
establish the validity of the transfer and the  acceptance by the  transferor or
transferees of the terms and conditions of such option.

     10. Termination of Employment

     In the event that the  employment of an employee to whom an option has been
granted  under  the  1997  Plan  shall be  terminated  (except  as set  forth in
Paragraph 11 below),  such option may be,  subject to the provisions of the 1997
Plan,  exercised  (to the extent that the  employee was entitled to do so at the
termination  of his  employment)  at any time within three (3) months after such
termination,  but not  later  than  the  date on which  the  option  terminates;
provided, however, that any option which is held by an employee whose employment
is terminated for cause or voluntarily without the consent of the Company shall,
to the extent not theretofore exercised,  automatically terminate as of the date
of  termination  of  employment.  As used  herein,  "cause"  shall mean  conduct
amounting to fraud,  dishonesty,  or engaging in competition or solicitations in
competition with the Company and breaches of any applicable employment agreement
between the Company and the  optionee.  Options  granted to employees  under the
1997 Plan shall not be  affected  by any change of duties or position so long as
the  holder  continues  to be a regular  employee  of the  Company or any of its
current or future  Subsidiaries or Parent. Any option agreement or any rules and
regulations  relating to the 1997 Plan may contain such  provisions as the Board
of Directors or the Committee,  as the case may be, shall approve with reference
to the determination of the date employment  terminates and the effect of leaves
of absence.  Nothing in the 1997 Plan or in any option  granted  pursuant to the
1997 Plan shall  confer upon any employee any right to continue in the employ of
the Company or any of the  Subsidiaries  or Parent or  affiliated  companies  or
interfere  in any way with the right of the  Company or any such  Subsidiary  or
Parent or affiliated companies to terminate such employment at any time.

     11. Death or Disability of Employee

     If an employee to whom an option has been granted under the 1997 Plan shall
die while  employed by the Company or a Parent or a  Subsidiary  or within three
(3) months after the termination of such employment  (other than termination for
cause or voluntary termination without the consent of the Company or the consent
of the Parent for an employee of the  Parent,  as the case may be),  such option
may be  exercised,  to the extent  exercisable  by the  employee  on the date of
death,  by a legatee or legatees of the employee under the employee's last will,
or by the employee's personal representative or distributees, at any time within
one year after the date of the employee's  death, but not later than the date on
which the option terminates.  In the event that the employment of an employee to
whom an option has been granted  under the 1997 Plan shall be  terminated as the
result of a disability,  such option may be exercised, to the extent exercisable
by the  employee  on the date of such  termination,  at any time within one year
after the date of such  termination,  but not  later  than the date on which the
option terminates.

     12. Adjustments Upon Changes in Capitalization, Etc.

     Notwithstanding  any  other  provision  of the  1997  Plan,  the  Board  of
Directors  or the  Committee,  as the case may be,  may,  at any  time,  make or
provide for such adjustments to the 1997 Plan, to the number and class of shares
issuable  thereunder or to any outstanding  options as it shall deem appropriate
to prevent dilution or enlargement of rights, including adjustments in the event
of  changes  in the  outstanding  Common  Stock by  reason  of stock  dividends,
split-ups, recapitalizations, mergers, consolidations, combinations or exchanges
of shares, separations, reorganizations, liquidations and the like. In the event
of any offer to holders of Common Stock generally relating to the acquisition of
their shares,


                                       49
<PAGE>


the  Board of  Directors  or the  Committee,  as the case may be,  may make such
adjustment as it deems  equitable in respect of outstanding  options and rights,
including in its discretion  revision of outstanding  options and rights so that
they  may be  exercisable  for  the  consideration  payable  in the  acquisition
transaction.  Any such determination by the Board of Directors or the Committee,
as the case may be, shall be conclusive.  Any fractional  shares  resulting from
such adjustments shall be eliminated.

     13. Effective Date

     The 1997 Plan shall become effective on June 12, 1997, the date of adoption
by the  Board  of  Directors,  subject  to  approval  of the  1997  Plan  by the
shareholders of the Company on or before June 11, 1998.

     14. Termination and Amendment

     The Board of  Directors  of the Company  may,  without the  approval of its
shareholders,  suspend,  terminate,  modify  or amend the 1997  Plan,  provided,
however,  that any amendment that would increase the aggregate  number of shares
which may be issued  under  the 1997  Plan,  materially  increase  the  benefits
accruing  to  participants  under  the  1997  Plan,  or  materially  modify  the
requirements  as to eligibility  for  participation  in the 1997 Plan,  shall be
subject to the approval of the  Company's  shareholder(s),  except that any such
increase  or  modification  that  may  result  from  adjustments  authorized  by
Paragraph 12 does not require  such  approval.  Except as provided  below and in
Paragraph 8(c) hereof, no suspension, termination,  modification or amendment of
the 1997 Plan shall  require the approval of any optionee.  Notwithstanding  the
foregoing,  no suspension,  termination,  modification  or amendment of the 1997
Plan shall be made  without  the  consent of the person to whom an option  shall
theretofore  have  been  granted  if it  adversely  effects  the  rights of such
optionee under such option.

     15. Miscellaneous

     As said term is used in the 1997 Plan,  the "Fair Market  Value" of a share
of Common  Stock on any day means:  (a) if the  principal  market for the Common
Stock  is  a  national  securities  exchange  or  the  National  Association  of
Securities  Dealers Automated  Quotations  System  ("NASDAQ),  the closing sales
price of the Common  Stock on such day as  reported  by such  exchange or market
system,  or on a consolidated  tape reflecting  transactions on such exchange or
market  system,  or (b) if the  principal  market for the Common  Stock is not a
national  securities  exchange and the Common Stock is not quoted on NASDAQ, the
mean  between the highest bid and lowest  asked  prices for the Common  Stock on
such day as reported by the National  Quotation Bureau,  Inc.;  provided that if
clauses (a) and (b) of this  paragraph  are both  inapplicable,  or if no trades
have been made or no quotes are available for such day, the Fair Market Value of
the Common Stock shall be determined by the Board of Directors or the Committee,
as the  case may be,  shall be  conclusive  as to the Fair  Market  Value of the
Common Stock.

     No shares of Common Stock shall be issued and delivered upon exercise of an
option  granted  under the 1997 Plan  unless and until (i) such shares of Common
Stock have been duly listed,  upon official  notice of issuance,  upon any stock
exchange(s) on which the Common Stock is listed,  (ii) a Registration  Statement
under the Securities Act of 1933, as amended,  with respect to such shares shall
be effective and any applicable  state  registration or  qualification  has been
complied with, or, in the opinion of either counsel to the Company or counsel to
the option holder  reasonably  acceptable to the Company,  exemptions  from such
federal and state  registration  requirements  are  available  and/or  (iii) the
person exercising such option delivers to the Company such documents, agreements
and  investment  and  other  representations  as the Board of  Directors  or the
Committee,  as the case may be, shall  determine to be in the best  interests of
the Company.

     During the term of the 1997 Plan,  the Board of Directors or the Committee,
as the case may be, in its discretion,  may offer one or more option holders the
opportunity  to  surrender  any or all  unexpired  options for  cancellation  or
replacement.  If any options are so  surrendered,  the Board of Directors or the
Committee,  as the case may be, may then grant new  Non-Qualified  or  Incentive
Options to such holders for the same or different numbers of shares at higher or
lower exercise prices than the surrendered options.  Such new options may have a
different  term and shall be subject to the provisions of the 1997 Plan the same
as any other option.

     Anything herein to the contrary notwithstanding,  the Board of Directors or
the Committee,  as the case may be, may, in their sole  discretion,  impose more
restrictive conditions on the exercise of an option granted pursuant to the 1997
Plan;  however,  any and all such  conditions  shall be  specified in the option
agreement limiting and defining such option.


                                       50
<PAGE>


     16. Privileges of Stock Ownership

     No person entitled to exercise any option granted under the 1997 Plan shall
have any of the rights or privileges of a shareholder  of the Company in respect
of any shares of stock issuable upon exercise of such option until  certificates
representing such shares shall have been issued.

     17. Compliance with SEC Regulations.

     It is the  Company's  intent that the 1997 Plan comply in all respects with
Rule  16b-3  of the Act  and  any  regulations  promulgated  thereunder.  If any
provision  of the 1997  Plan is later  found not to be in  compliance  with said
Rule, the provisions shall be deemed null and void.
