Item 1. Business

General

Part I

Hudson Technologies, Inc. (“Hudson” or the “Company”), incorporated under the laws of New York on January 11, 1991, is a refrigerant
services  company  providing  innovative  solutions  to  recurring  problems  within  the  refrigeration  industry.  Hudson  has  proven,  reliable
programs  that  meet  customer  refrigerant  needs  by  providing  environmentally  sustainable  solutions  from  initial  sale  of  refrigerant  gas
through  recovery,  reclamation  and  reuse,  peak  operating  performance  of  equipment  through  energy  efficiency  and  emergency  air
conditioning and refrigeration system repair, to final refrigerant disposal and carbon credit trading.

The Company’s operations consist of one reportable segment. The Company's products and services are primarily used in commercial air
conditioning,  industrial  processing  and  refrigeration  systems,  and  include  refrigerant  and  industrial  gas  sales,  refrigerant  management
services  consisting  primarily  of  reclamation  of  refrigerants  and  RefrigerantSide®  Services  performed  at  a  customer's  site.
RefrigerantSide®  Services  consists  of  system  decontamination  to  remove  moisture,  oils  and  other  contaminants  intended  to  restore
systems to designed capacity. In addition, the Company’s SmartEnergy OPS® service is a web-based real time continuous monitoring
service applicable to a facility’s refrigeration systems and other energy systems. The Company’s Chiller Chemistry® and Chill Smart®
services are also predictive and diagnostic service offerings. As a component of the Company’s products and services, the Company also
participates in the generation of carbon offset projects. The Company operates principally through its wholly-owned subsidiary, Hudson
Technologies Company, and Aspen Refrigerants (“Aspen” or “ARI”), a division of Hudson Technologies Company. Unless the context
requires otherwise, references to the “Company”, “Hudson”, “we", “us”, “our”, or similar pronouns refer to Hudson Technologies, Inc.
and its subsidiaries.

The Company’s executive offices are located at 300 Tice Boulevard, Suite 290, Woodcliff Lake, New Jersey and its telephone number is
(845) 735-6000. The Company maintains a website at www.hudsontech.com, the contents of which are not incorporated into this filing.

Industry Background

The Company participates in an industry that is highly regulated, and changes in the regulations affecting our business could affect our
operating results. Currently the Company purchases virgin hydrofluoro-olefins (“HFO”) and hydrofluorocarbon (“HFC”) refrigerants and
reclaimable,  primarily  hydrochlorofluorocarbon  (“HCFC”),  HFC  and  chlorofluorocarbon  (“CFC”)  refrigerants  from  suppliers  and  its
customers. Effective January 1, 1996, the Clean Air Act, as amended (the “Act”) prohibited the production of virgin CFC refrigerants
and limited the production of virgin HCFC refrigerants. Effective January 2004, the Act further limited the production of virgin HCFC
refrigerants and federal regulations were enacted which established production and consumption allowances for HCFC refrigerants and
which  imposed  limitations  on  the  importation  of  certain  virgin  HCFC  refrigerants.  Under  the  Act,  production  of  certain  virgin  HCFC
refrigerants was phased out on December 31, 2019 and production of all virgin HCFC refrigerants is scheduled to be phased out by 2030.

The Act, and the federal regulations enacted under authority of the Act, have mandated and/or promoted responsible use practices in the
air conditioning and refrigeration industry, which are intended to minimize the release of refrigerants into the atmosphere and encourage
the recovery and re-use of refrigerants. The Act prohibits the venting of CFC, HFC and HCFC refrigerants, and prohibits and/or phases
down the production of CFC, HCFC and HFC refrigerants.

The Act also mandates the recovery of CFC and HCFC refrigerants and also promotes and encourages re-use and reclamation of CFC
and  HCFC  refrigerants.  Under  the  Act,  owners,  operators  and  companies  servicing  cooling  equipment  utilizing  CFC  and  HCFC
refrigerants are responsible for the integrity of the systems regardless of the refrigerant being used. In November 2016, the EPA issued a
final rule extending these requirements to HFCs and to certain other refrigerants that are approved by the EPA as alternatives for CFC
and HCFC refrigerants (the “608 Rule”).

HFC refrigerants are used as substitutes for CFC and HCFC refrigerants in certain applications. As a result of the increasing restrictions
and  limitations  on  the  production  and  use  of  CFC  and  HCFC  refrigerants,  various  sectors  of  the  air  conditioning  and  refrigeration
industry have been replacing or modifying equipment that utilize CFC and HCFC refrigerants and have been transitioning to equipment

3

Table of Contents

that utilize HFC refrigerants and hydrofluoro-olefins (“HFO”). Certain HFC refrigerants are highly weighted greenhouse gases that are
believed to contribute to global warming and climate change and, as a result, are now subject to various state regulations relating to the
sale,  use  and  emissions  of  HFC  refrigerants,  as  well  as  federal  restrictions  on  the  production  and  consumption  of  HFCs  (as  set  forth
below). The Company expects that HFC refrigerants eventually will be replaced by HFOs or other types of products with lower global
warming potentials.

In October 2016, more than 200 countries, including the United States, agreed to amend the Montreal Protocol to phase down production
of HFCs by 85% by 2047. The amendment establishes timetables for all developed and developing countries to freeze and then reduce
production and use of HFCs, with the first reductions by developed countries in 2019. The amendment became effective January 1, 2019
as more than twenty countries have ratified the amendment.

In December 2020, Congress enacted the American Innovation and Manufacturing Act of 2020 (the “AIM Act”) in the United States that
will  require  the  phasedown  of  virgin  production  and  consumption  of  HFCs,  which  will  also  increase  opportunities  for  reclamation  of
HFCs.

AIM Act

On September 23, 2021, the United States Environmental Protection Agency (“EPA”) issued the final rule establishing the framework to
allocate allowances for virgin production and consumption of HFCs. The EPA is responsible for the administration of the HFC phase
down enacted by Congress under the AIM Act.

The AIM Act directs the EPA to address the reduction in virgin HFCs and provides authority to do so in three respects:

1) phase down the production and consumption of listed HFCs,
2) manage these HFCs and their substitutes, and
3)

facilitate the transition to next-generation technologies.

Congress also required that EPA shall consider ways to promote reclamation in all phases of its implementation of the AIM Act. The
final rule introduces a stepdown of 10% from baseline levels and a subsequent allowance rule must establish a cumulative 40% reduction
in the baseline for 2024. Hudson received an allocation allowance for calendar year 2022 equal to approximately 3 million Metric Tons
Exchange Value Equivalents, or 1% of the total HFC consumption, with allowances for 2023 and beyond to be determined at a later date.
Reclamation will be critical to maintaining necessary HFC supply levels to ensure an orderly phasedown.

Products and Services

Sustainability

From its inception, the Company has sold refrigerants, and has provided refrigerant reclamation and refrigerant management services that
are designed to recover and reuse refrigerants, thereby protecting the environment from release of refrigerants to the atmosphere and the
corresponding  ozone  depletion  and  global  warming  impact  and  supporting  the  circular  economy.  The  reclamation  process  allows  the
refrigerant to be re-used thereby eliminating the need to destroy or manufacture additional refrigerant and eliminating the corresponding
impact  to  the  environment  associated  with  the  destruction  and  manufacturing.    The  Company  believes  it  is  the  largest  refrigerant
reclaimer in the United States.  In addition, the Company participates in the creation and monetization of verified emission reductions
utilizing third party protocols.

The  Company  provides  a  complete  offering  of  refrigerant  management  services,  which  primarily  include  reclamation  of  refrigerants,
laboratory  testing  through  the  Company’s  laboratory,  which  has  been  certified  by  the  Air  Conditioning,  Heating  and  Refrigeration
Institute (“AHRI”), and banking (storage) services tailored to individual customer requirements. The Company also separates “crossed”
(i.e. commingled) refrigerants and provides re-usable cylinder refurbishment and hydrostatic testing services.

The  Company  has  also  created  alternative  solutions  to  reactive  and  preventative  maintenance  procedures  that  are  performed  on
commercial  and  industrial  refrigeration  systems.    These  services,  known  as  RefrigerantSide®  Services,  reduce  the  system’s  energy
consumption and improve the system’s operating performance, and complement the Company’s refrigerant sales and refrigerant

Table of Contents

reclamation  and  management  services.  These  services  also  preserve  system  refrigerant  charges,  reducing  the  need  for  manufacture  of
additional refrigerant.

Refrigerant and Industrial Gas Sales

The Company sells reclaimed and virgin (new) refrigerants to a variety of customers in the air conditioning and refrigeration industry.
The Company continues to sell reclaimed CFC based refrigerants, which are no longer manufactured. Virgin refrigerants are purchased
by  the  Company  from  several  suppliers  and  resold  by  the  Company.  Additionally,  the  Company  regularly  purchases  used  or
contaminated  refrigerants,  from  many  different  sources,  which  refrigerants  are  then  reclaimed  using  the  Company's  high  speed
proprietary reclamation equipment, its proprietary Zugibeast® system, and then are resold by the Company.

The Company also sells industrial gases to a variety of industry customers, predominantly to users in or involved with the US Military.
 In July 2016 the Company was awarded, as prime contractor, a five-year contract, together with a five-year renewal option which has
been  exercised  in  July  2021,  by  the  United  States  Defense  Logistics  Agency  (“DLA”)  for  the  management,  supply,  and  sale  of
refrigerants, compressed gases, cylinders and related services.

Carbon Offset Projects

CFC refrigerants are ozone depleting substances and are also highly weighted greenhouse gases that contribute to global warming and
climate  change.  The  destruction  of  CFC  refrigerants  may  be  eligible  for  verified  emission  reductions  that  can  be  converted  and
monetized  into  carbon  offset  credits,  which  then  can  be  traded  in  the  emerging  carbon  offset  markets.  The  Company  is  pursuing
opportunities to acquire CFC refrigerants and is developing relationships within the emerging environmental markets in order to develop
opportunities for the creation and monetization of verified emission reductions from the destruction of CFC refrigerants.

In October 2015, the American Carbon Registry (“ACR”) established a methodology to provide, among other things, a quantification
framework  for  the  creation  of  carbon  offset  credits  for  the  use  of  certified  reclaimed  HFC  refrigerants.  The  Company  is  pursuing
opportunities to acquire HFC refrigerants and is developing relationships within the emerging environmental markets in order to develop
opportunities for the creation and monetization of verified emission reductions from the reclamation of HFC refrigerants.

RefrigerantSide® Services

The Company provides decontamination and recovery services that are performed at a customer’s site through the use of portable, high
volume,  high-speed  proprietary  equipment,  including  the  patented  Zugibeast®  system.    Certain  of  these  RefrigerantSide®  Services,
which  encompass  system  decontamination,  and  refrigerant  recovery  and  reclamation,  are  also  proprietary  and  are  covered  by  process
patents.

In  addition  to  the  decontamination  and  recovery  services  previously  described,  the  Company  also  provides  predictive  and  diagnostic
services for its customers.  The Company offers diagnostic services that are intended to predict potential problems in air conditioning,
process cooling and refrigeration systems before they occur.  The Company’s Chiller Chemistry® offering integrates several fluid tests of
an operating system and the corresponding laboratory results into an engineering report providing its customers with an understanding of
the current condition of the fluids, the cause for any abnormal findings and the potential consequences if the abnormal findings are not
remediated.  Fluid Chemistry®, an abbreviated version of the Company’s Chiller Chemistry® offering, is designed to quickly identify
systems that require further examination.

The Company has also been awarded several US patents for its SmartEnergy OPS®, which is a system for measuring, modifying and
improving  the  efficiency  of  energy  systems,  including  air  conditioning  and  refrigeration  systems,  in  industrial  and  commercial
applications.  This  service  is  a  web-based  real  time  continuous  monitoring  service  applicable  to  a  facility’s  chiller  plant  systems.  The
SmartEnergy  OPS®  offering  enables  customers  to  monitor  and  improve  their  chiller  plant  performance  and  proactively  identify  and
correct system inefficiencies. SmartEnergy OPS® is able to identify specific inefficiencies in the operation of chiller plant systems and,
when used with Hudson’s RefrigerantSide ® Services, can increase the efficiency of the operating systems thereby reducing energy usage
and costs. Improving the system efficiency reduces power consumption thereby directly reducing CO 2 emissions at the power plants or
onsite.   Lastly, the Company’s ChillSmart® offering, which combines the system optimization with the Company’s Chiller Chemistry ®
offering, provides a snapshot of a packaged chiller’s operating efficiency and health. ChillSmart® provides a very effective predictive
maintenance tool and helps our customers to identify the operating chillers that cause higher operating costs.

in  the  US  and  internationally  and  have  developed,  and  are  currently  delivering,  training  curriculums  in  12  different  countries.    The
Company’s staff have completed more than 200 industrial ESAs in the US and internationally.

Suppliers

The Company purchases refrigerants from a variety of manufacturers, wholesalers, distributors, bulk gas brokers and from other sources
within the air conditioning, refrigeration and automotive aftermarket industries.

Customers

The  Company  provides  its  products  and  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.  The  Company  generates  sales  by  customer  purchase  order  on  a  real-time  basis  and
therefore does not carry a backlog of sales.

For the year ended December 31, 2021, one customer accounted for 10% of the Company’s revenues and at December 31, 2021, there
were $3.1 million of outstanding receivables from this customer. For the year ended December 31, 2020, one customer accounted for
14% of the Company’s revenues and at December 31, 2020, there were $2.9 million of outstanding receivables from this customer.

Marketing

Marketing  programs  are  conducted  through  the  efforts  of  the  Company's  executive  officers,  marketing  personnel  and  Company  sales
personnel. Hudson employs various marketing methods, including digital marketing, segment targeted outreach, social media, trade and
industry  events,  webinars,    in-person  solicitation,  print  advertising,  response  to  quotation  requests  and  the  internet  through  the
Company’s websites (www.hudsontech.com and www.ASPENRefrigerants.com). Information on the Company's websites are not part of
this report.

The Company's sales personnel are compensated on a combination of a base salary and commission. The Company's executive officers
devote significant time and effort to customer relationships.

Competition

The  Company  competes  primarily  on  the  basis  of  the  performance  of  its  proprietary  high  volume,  high-speed  equipment  used  in  its
operations, the breadth of services offered by the Company, including proprietary RefrigerantSide® Services and other on-site services,
and price, particularly with respect to refrigerant sales.

The  Company  competes  with  numerous  regional  and  national  companies  that  market  reclaimed  and  virgin  refrigerants  and  provide
refrigerant reclamation services. Certain of these competitors may possess greater financial, marketing, distribution and other resources
for the sale and distribution of refrigerants than the Company.

Hudson's RefrigerantSide® Services provide solutions to certain problems within the refrigeration industry and, as such, the demand and
market acceptance for these services are subject to uncertainty. Competition for these services primarily consists of traditional methods
of  solving  the  industry's  problems.  The  Company’s  marketing  strategy  is  to  educate  the  marketplace  that  its  alternative  solutions  are
available and that RefrigerantSide® Services are superior to traditional methods.

Risk Management

The  Company  carries  insurance  coverage  that  it  considers  sufficient  to  protect  the  Company's  assets  and  operations.  The  Company
attempts to operate in a professional and prudent manner and to reduce potential liability risks through specific risk management efforts,
including ongoing employee training.

6

Table of Contents

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 held 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  $10,000,000  per  occurrence,  and  $10,000,000  annual  aggregate,  for  events
occurring subsequent to November 1996.

Government Regulation

The  business  of  refrigerant  and  industrial  gas  sales,  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  EPA,  the
United States Occupational Safety and Health Administration (“OSHA”) and the United States Department of Transportation (“DOT”).

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  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  Act,  reclaimed  refrigerant  must  satisfy  the  same  purity  standards  as  newly  manufactured,  virgin  refrigerants  in
accordance  with  standards  established  by  AHRI  prior  to  resale  to  a  person  other  than  the  owner  of  the  equipment  from  which  it  was
recovered. The EPA administers a certification program pursuant to which applicants certify to reclaim refrigerants in compliance with
AHRI standards. The Company is one of only four certified refrigerant testing laboratories in the United States under AHRI’s laboratory
certification  program,  which  is  a  voluntary  program  that  certifies  the  ability  of  a  laboratory  to  test  refrigerant  in  accordance  with  the
AHRI  700  standard.  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 may also be subject to regulations adopted by the EPA which impose reporting requirements arising out of the importation
of certain HCFCs, and arising out of the importation, purchase, production, use and/or emissions of certain greenhouse gases, including
HFCs.

The  Company  is  also  subject  to  regulations  adopted  by  the  DOT  which  classify  most  refrigerants  and  industrial  gases  handled  by  the
Company as hazardous materials or substances and imposes requirements for handling, packaging, labeling and transporting refrigerants
and which regulate the use and operation of the Company’s commercial motor vehicles used in the Company’s business.

The Resource Conservation and Recovery Act of 1976, as amended ("RCRA"), requires facilities that treat, store or dispose of hazardous
wastes to 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, as amended, requires the annual reporting by the Company of
Emergency and Hazardous Chemical Inventories (Tier II reports) to the various states in which the Company operates and requires the
Company 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

7

Table of Contents

transportation  of  hazardous  substances.  Almost  all  states  have  similar  statutes  regulating  the  handling  and  storage  of  hazardous
substances,  hazardous  wastes  and  non-hazardous  wastes.  Many  such  statutes  impose  requirements  that  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, as amended mandates requirements for a 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. The Company is also subject to regulations adopted by the California Air
Resources  Board  which  impose  certain  reporting  requirements  arising  out  of  the  reclamation  and  sale  of  refrigerants  that  takes  place
within the State of California.

The Company believes that it is in material compliance with all applicable regulations material to its business operations.

Quality Assurance & Environmental Compliance

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

Human Capital Resources

On  March  4,  2022,  the  Company  had  217  full  time  employees  including  air  conditioning  and  refrigeration  technicians,  chemists,
engineers, sales and administrative personnel. None of the Company's employees are represented by a union. The Company believes it
has good relations with its employees.

Patents and Proprietary Information

The Company holds several U.S. and foreign patents, as well as pending patent applications, related to certain RefrigerantSide® Services
and  supporting  systems  developed  by  the  Company  for  systems  and  processes  for  measuring  and  improving  the  efficiency  of
refrigeration systems, and for certain refrigerant recycling and reclamation technologies. These patents will expire between January 2023
and July 2035.

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 or processes 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 or processes, 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.

SEC Filings

The  Company  makes  available  on  its  internet  website  copies  of  its  Annual  Report  on  Form  10-K,  Quarterly  Reports  on  Form  10-Q,
Current  Reports  on  Form  8-K,  and  amendments  thereto,  as  soon  as  reasonably  practicable  after  they  are  filed  with  the  Securities  and
Exchange Commission.

Item 1A. Risk Factors

There  are  many  important  factors,  including  those  discussed  below  (and  above  as  described  under  “Patents  and  Proprietary
Information”),  that  have  affected,  and  in  the  future  could  affect  Hudson’s  business  including,  but  not  limited  to,  the  factors  discussed
below, which should be reviewed carefully together with the other information contained in this report. Some of the factors are beyond
Hudson’s control and future trends are difficult to predict.

Risks Related to Business Strategy and Operations

Our existing and future debt obligations could impair our liquidity and financial condition.

Our  existing  credit  facilities,  consisting  of  an  asset-based  lending  facility  of  up  to  $90  million  from  Wells  Fargo  Bank,  National
Association (“Wells Fargo Bank”) and other lenders, and a term loan of $85 million from funds advised by TCW Asset Management
Company, LLC, are secured by substantially all of our assets and the asset-based lending facility contains formulas that limit the amount
of our future borrowings under that facility. Moreover, the terms of our credit facilities also include financial and negative covenants that,
among other things, may limit our ability to incur additional indebtedness. If we violate any loan covenants and do not obtain a waiver
from  our  lenders,  our  indebtedness  under  the  credit  facilities  would  become  immediately  due  and  payable,  and  the  lenders  could
foreclose on their security, which could materially adversely affect our business and future financial condition and could require us to
curtail or otherwise cease our existing operations.

Our revenues, results of operations and cash flows could be materially and adversely affected by changes in commodity prices.

Our revenues, results of operations and cash flows are affected by market prices for refrigerant gases. Commodity prices generally are
affected  by  a  wide  range  of  factors  beyond  our  control,  including  weather,  seasonality,  the  availability  and  adequacy  of  supply,
government regulation and policies and general political and economic conditions. We are exposed to fluctuating commodity prices as
the result of our inventory of various refrigerant gases. At any time, our inventory levels may be substantial. We have processes in place
to monitor exposures to these risks and engage in strategies to manage these risks. If these controls and strategies are not successful in
mitigating our exposure to these fluctuations, we could be materially and adversely affected.

Our business has been impacted by the COVID-19 pandemic.

The public health crisis caused by the COVID-19 pandemic and the measures being taken by governments, businesses, including us, and
the  public  at  large  to  limit  COVID-19's  spread  may  have  certain  negative  impacts  on  our  business  including,  without  limitation,  the
following:

●

●

●

●

We may experience a further decrease in sales due to the COVID-19 pandemic. In particular, sales of our products to customers,
such  as  schools,  offices  and  government  facilities,  which  have  shut  down,  have  been  negatively  impacted.  If  the  COVID-19
pandemic  intensifies  and  expands  geographically,  its  negative  impacts  on  our  sales  and  collectability  of  receivables  could  be
more prolonged and may become more severe.

Although we have not experienced this during 2021, future potential disruptions in supply chains may place constraints on our
ability to source refrigerants, which may increase our processing costs.

Governmental authorities in the United States and throughout the world may continue to increase or impose new income taxes
or indirect taxes, or revise interpretations of existing tax rules and regulations, as a means of financing the costs of stimulus and
other measures enacted or taken, or that may be enacted or taken in the future, to protect populations and economies from the
impact of the COVID-19 pandemic. Such actions could have an adverse effect on our results of operations and cash flows.

As a result of the COVID-19 pandemic, including related governmental guidance or directives, we have required most office-
based employees to work remotely. We may experience reductions in productivity and disruptions to our business routines while
our remote work policy remains in place.

Table of Contents

● Attempting to comply with rapidly evolving and conflicting legal requirements regarding vaccination and/or mandatory testing

of our workforce.

● Actions we have taken or may take, or decisions we have made or may make, as a consequence of the COVID-19 pandemic

may result in legal claims or litigation against us.

Any  of  the  negative  impacts  of  the  COVID-19  pandemic,  including  those  described  above,  alone  or  in  combination  with  others,  may
have a material adverse effect on our results of operations, financial condition and cash flows. The full extent to which the COVID-19
pandemic will negatively affect our results of operations, financial condition and cash flows will depend on future developments that are
highly  uncertain  and  cannot  be  predicted,  including  the  scope  and  duration  of  the  pandemic  and  actions  taken  by  governmental
authorities and other third parties in response to the pandemic.

We may need additional financing to satisfy our future capital requirements, which may not be readily available to us.

Our capital requirements may be significant in the future. We may incur additional expenses in the development and implementation of
our  operations.  Due  to  fluctuations  in  the  price,  demand  and  availability  of  new  refrigerants,  our  existing  credit  facility  led  by  Wells
Fargo  Bank  that  expires  in  March  2027  may  not  in  the  future  be  sufficient  to  provide  all  of  the  capital  that  we  need  to  acquire  and
manage our inventories of new refrigerant. As a result, we may be required to seek additional equity or debt financing in order to develop
our RefrigerantSide® Services business, our refrigerant sales business and our other businesses. We have no current arrangements with
respect to, or sources of, additional financing other than our existing credit facility and term loan. There can be no assurance that we will
be able to obtain any additional financing on terms acceptable to us or at all. Our inability to obtain financing, if and when needed, could
materially  adversely  affect  our  business  and  future  financial  condition  and  could  require  us  to  curtail  or  otherwise  cease  our  existing
operations.

Adverse weather or economic downturn could adversely impact our financial results.

Our business could be negatively impacted by adverse weather or economic downturns. Weather is a significant factor in determining
market demand for the refrigerants sold by us, and to a lesser extent, our RefrigerantSide® Services. Unusually cool temperatures in the
spring and summer tend to depress demand for, and price of, refrigerants we sell. Protracted periods of cooler than normal spring and
summer weather could result in a substantial reduction in our sales which could adversely affect our financial position as well as our
results  of  operations.  An  economic  downturn  could  cause  customers  to  postpone  or  cancel  purchases  of  the  Company’s  products  or
services. Either or both of these conditions could have severe negative implications to our business that may exacerbate many of the risk
factors we identified in this report but not limited, to the following:

Liquidity

These conditions could reduce our liquidity, which could have a negative impact on our financial condition and results of operations.

Demand

These conditions could lower the demand and/or price for our product and services, which would have a negative impact on our results
of operations.

Financial Covenants

These conditions could impact our ability to meet our loan covenants which, if we are unable to obtain a waiver from our lenders, could
materially  adversely  affect  our  business  and  future  financial  condition  and  could  require  us  to  curtail  or  otherwise  cease  our  existing
operations.

Our business is impacted by customer concentration.

In  July  2016,  we  were  awarded,  as  prime  contractor,  a  five-year  contract,  including  a  five-year  renewal  option  (which  has  been
exercised), by the United States Defense Logistics Agency (“DLA”) for the management and supply of refrigerants, compressed gases,
cylinders and related items to US Military commands and installations, Federal civilian agencies and foreign militaries. Our contract

10

Table of Contents

with  DLA  expires  in  July  2026.  For  the  years  ended  December  31,  2021  and  2020,  the  DLA  accounted  for  10%  and  14%  of  our
revenues. The loss of DLA as a customer could have a material adverse effect on our financial position and results of operations.

Risks Related to Regulatory and Environmental Matters

The nature of our business exposes us to potential liability.

The  refrigerant  recovery  and  reclamation  industry  involves  potentially  significant  risks  of  statutory  and  common  law  liability  for
environmental damage and personal injury. We, and in certain instances, our officers, directors and employees, may be subject to claims
arising from our 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.  We  may  be  strictly  liable  for  damages,  which  could  be  substantial,  regardless  of
whether we exercised due care and complied with all relevant laws and regulations. Our current insurance coverage may not be sufficient
to cover potential claims, and adequate levels of insurance coverage may not be available in the future at a reasonable cost. A partially or
completely uninsured claim against us, if successful and of sufficient magnitude would have a material adverse effect on our business
and financial condition.

Our business and financial condition is substantially dependent on the sale and continued environmental regulation of refrigerants.

Our  business  and  prospects  are  largely  dependent  upon  continued  regulation  of  the  use  and  disposition  of  refrigerants.  Changes  in
government regulations relating to the emission of refrigerants into the atmosphere could have a material adverse effect on us. Failure by
government authorities to otherwise continue to enforce existing regulations or significant relaxation of regulatory requirements could
also adversely affect demand for our services and products.

Our business is subject to significant regulatory compliance burdens.

The refrigerant reclamation and management business is subject to extensive, stringent and frequently changing federal, state and local
laws  and  substantial  regulation  under  these  laws  by  governmental  agencies,  including  the  EPA,  the  OSHA  and  DOT.  Although  we
believe that we are in material compliance with all applicable regulations material to our business operations, amendments to existing
statutes and regulations or adoption of new statutes and regulations that affect the marketing and sale of refrigerant could require us to
continually  alter  our  methods  of  operation  and/or  discontinue  the  sale  of  certain  of  our  products  resulting  in  costs  to  us  that  could  be
substantial.  We  may  not  be  able,  for  financial  or  other  reasons,  to  comply  with  applicable  laws,  regulations  and  permit  requirements,
particularly as we seek to enter into new geographic markets. Our failure to comply with applicable laws, rules or regulations or permit
requirements  could  subject  us  to  civil  remedies,  including  substantial  fines,  penalties  and  injunctions,  as  well  as  possible  criminal
sanctions, which would, if of significant magnitude, materially adversely impact our operations and future financial condition.

A number of factors could negatively impact the price and/or availability of refrigerants, which would, in turn, adversely affect our
business and financial condition.

Refrigerant sales continue to represent a significant majority of our revenues. Therefore, our business is substantially dependent on the
availability of both new and used refrigerants in large quantities, which may be affected by several factors including, without limitation:
(i) commercial production and consumption limitations imposed by the Act and legislative limitations and ban on HCFC refrigerants;
(ii) the amendment to the Montreal Protocol, if ratified, and any legislation and regulation enacted to implement the amendment, could
impose limitations on production and consumption of HFC refrigerants; (iii) introduction of new refrigerants and air conditioning and
refrigeration equipment; (iv) price competition resulting from additional market entrants; (v) changes in government regulation on the
use  and  production  of  refrigerants;  and  (vi)  reduction  in  price  and/or  demand  for  refrigerants.  Sufficient  amounts  of  new  and/or  used
refrigerants may not be available to us in the future, particularly as a result of the further phase down of HFC production, or may not be
available on commercially reasonable terms. Additionally, we may be subject to price fluctuations, periodic delays or shortages of new
and/or used refrigerants. Our failure to obtain and resell sufficient quantities of virgin refrigerants on commercially reasonable terms, or
at  all,  or  to  obtain,  reclaim  and  resell  sufficient  quantities  of  used  refrigerants  would  have  a  material  adverse  effect  on  our  operating
margins and results of operations.

Issues relating to potential global warming and climate change could have an impact on our business.

Refrigerants are considered to be strong greenhouse gases that are believed to contribute to global warming and climate change and are
now  subject  to  various  state  and  federal  regulations  relating  to  the  sale,  use  and  emissions  of  refrigerants.  Current  and  future  global
warming  and  climate  change  or  related  legislation  and/or  regulations  may  impose  additional  compliance  burdens  on  us  and  on  our
customers and suppliers which could potentially result in increased administrative costs, decreased demand in the marketplace for our
products,  and/or  increased  costs  for  our  supplies  and  products.  In  addition,  an  amendment  to  the  Montreal  Protocol  has  established
timetables for all developed and developing countries to freeze and then reduce production and use of HFCs by 85% by 2047, with the
first reductions by developed countries in 2019. The amendment became effective January 1, 2019. In December 2020, legislation was
enacted in the United States that will require the phasedown of virgin production of HFCs.

Risks Related to Our Common Stock and Other General Risks

As a result of competition, and the strength of some of our competitors in the market, we may not be able to compete effectively.

The markets for our services and products are highly competitive. We compete with numerous regional and national companies which
provide  refrigerant  recovery  and  reclamation  services,  as  well  as  companies  which  market  and  deal  in  new  and  reclaimed  alternative
refrigerants, including certain of our suppliers, some of which possess greater financial, marketing, distribution and other resources than
us. We also compete with numerous manufacturers of refrigerant recovery and reclamation equipment. Certain of these competitors have
established  reputations  for  success  in  the  service  of  air  conditioning  and  refrigeration  systems.  We  may  not  be  able  to  compete
successfully, particularly as we seek to enter into new markets.

We have the ability to designate and issue preferred stock, which may have rights, preferences and privileges greater than Hudson’s
common stock and which could impede a subsequent change in control of us.

Our Certificate of Incorporation authorizes our Board of Directors to issue up to 5,000,000 shares of “blank check” preferred stock and to
fix the rights, preferences, privileges and restrictions, including voting rights, of these shares, without further shareholder approval. The
rights of the holders of our common stock will be subject to, and may be adversely affected by, the rights of holders of any additional
preferred stock that may be issued by us in the future. Our ability to issue preferred stock without shareholder approval could have the
effect of making it more difficult for a third party to acquire a majority of our voting stock, thereby delaying, deferring or preventing a
change in control of us.

If  our  common  stock  were  delisted  from  NASDAQ  it  could  be  subject  to  “penny  stock”  rules  which  would  negatively  impact  its
liquidity and our shareholders’ ability to sell their shares.

Our common stock is currently listed on the NASDAQ Capital Market. We must comply with numerous NASDAQ Marketplace rules in
order  to  continue  the  listing  of  our  common  stock  on  NASDAQ.  There  can  be  no  assurance  that  we  can  continue  to  meet  the
rules required to maintain the NASDAQ listing of our common stock. If we are unable to maintain our listing on NASDAQ, the market
liquidity of our common stock may be severely limited.

Our management has significant control over our affairs.

Currently, our officers and directors collectively beneficially own approximately 10% of our outstanding common stock. Accordingly,
our officers and directors are in a position to significantly affect major corporate transactions and the election of our directors. There is
no provision for cumulative voting for our directors.

We may fail to successfully integrate any additional acquisitions made by us into our operations.

As part of our business strategy, we may look for opportunities to grow by acquiring other product lines, technologies or facilities that
complement  or  expand  our  existing  business.  We  may  be  unable  to  identify  additional  suitable  acquisition  candidates  or  negotiate
acceptable  terms.  In  addition,  we  may  not  be  able  to  successfully  integrate  any  assets,  liabilities,  customers,  systems  or  management
personnel  we  may  acquire  into  our  operations  and  we  may  not  be  able  to  realize  related  revenue  synergies  and  cost  savings  within
expected time frames. There can be no assurance that we will be able to successfully integrate any prior or future acquisition.

Our information technology systems, processes, and sites may suffer interruptions, failures, or attacks which could affect our ability
to conduct business.

Our information technology systems provide critical data connectivity, information and services for internal and external users. These
include, among other things, processing transactions, summarizing and reporting results of operations, complying with regulatory, legal
or tax requirements, storing project information and other processes necessary to manage the business. Our systems and technologies, or
those  of  third  parties  on  which  we  rely,  could  fail  or  become  unreliable  due  to  equipment  failures,  software  viruses,  cyber  threats,
terrorist  acts,  natural  disasters,  power  failures  or  other  causes.  Cybersecurity  threats  are  evolving  and  include,  but  are  not  limited  to,
malicious software, cyber espionage, attempts to gain unauthorized access to our sensitive information, including that of our customers,
suppliers,  and  subcontractors,  and  other  electronic  security  breaches  that  could  lead  to  disruptions  in  mission  critical  systems,
unauthorized release of confidential or otherwise protected information, and corruption of data. Although we utilize various procedures
and  controls  to  monitor  and  mitigate  these  threats,  there  can  be  no  assurance  that  these  procedures  and  controls  will  be  sufficient  to
prevent security threats from materializing. If any of these events were to materialize, the costs related to cyber or other security threats
or disruptions may not be fully insured or indemnified and could have a material adverse effect on our reputation, operating results, and
financial condition.

The number of record holders of the Company's common stock was approximately 104 as of March 10, 2022. The Company believes
that there are approximately 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 on its common stock in
the foreseeable future. In addition, the Company has a credit facility with Wells Fargo Bank, National Association and a separate term
loan that, among other things, restrict the Company's ability to declare or pay any cash dividends on its capital stock.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Certain  statements,  contained  in  this  section  and  elsewhere  in  this  Form  10-K,  constitute  “forward-looking  statements”  within  the
meaning  of  the  Private  Securities  Litigation  Reform  Act  of  1995.  Such  forward-looking  statements  involve  a  number  of  known  and
unknown risks, uncertainties and other factors which may cause the actual results, performance or achievements of the Company to be
materially  different  from  any  future  results,  performance  or  achievements  expressed  or  implied  by  such  forward-looking  statements.
Such factors include, but are not limited to, changes in the laws and regulations affecting the industry, changes in the demand and price
for  refrigerants  (including  unfavorable  market  conditions  adversely  affecting  the  demand  for,  and  the  price  of  refrigerants),  the
Company's ability to source refrigerants, regulatory and economic factors, seasonality, competition, litigation, the nature of supplier or
customer  arrangements  that  become  available  to  the  Company  in  the  future,  adverse  weather  conditions,  possible  technological
obsolescence of existing products and services, possible reduction in the carrying value of long-lived assets, estimates of the useful life
of  its  assets,  potential  environmental  liability,  customer  concentration,  the  ability  to  obtain  financing,  the  ability  to  meet  financial
covenants under our financing facilities, any delays or interruptions in bringing products and services to market, the timely availability of
any requisite permits and authorizations from governmental entities and third parties as well as factors relating to doing business outside
the  United  States,  including  changes  in  the  laws,  regulations,  policies,  and  political,  financial  and  economic  conditions,  including
inflation, interest and currency exchange rates, of countries in which the Company may seek to conduct business, and integration of any
other assets it acquires from third parties into its operations, the impact of the COVID-19 pandemic, and other risks detailed in this report
and in the Company’s other subsequent filings with the Securities and Exchange Commission (“SEC”). The words “believe”, “expect”,
“anticipate”, “may”, “plan”, “should” and similar expressions identify forward-looking statements. Readers are cautioned not to place
undue reliance on these forward-looking statements, which speak only as of the date the statement was made.

Impact of COVID-19 Pandemic

During  the  years  ended  December  31,  2021  and  2020,  the  effects  of  a  novel  strain  of  coronavirus  ("COVID-19")  pandemic  and  the
related  actions  by  governments  around  the  world  to  attempt  to  contain  the  spread  of  the  virus  have  materially  impacted  the  global
economy.

In response to the COVID-19 outbreak and business disruption, we have four primary priorities:

●

●

●

●

To ensure the health and safety of Hudson employees

To keep our products in supply and to maintain the quality and safety of our products

To best serve our customers across all channels as they adapt to the shifting demands of consumers during the crisis

To best position ourselves to emerge strong when this crisis ends

We operate in a “critical infrastructure industry” and are an essential business as defined by the United States government as we procure,
process, service and deliver refrigerants to the government and wholesale and retail organizations, which also service both residential

14

Table of Contents

homes and commercial institutions throughout the United States. While the conditions in the United States and the economy have been
impacted by the pandemic, we have been effectively running our operations, including the following:

-

-

Keeping all plants open, while maintaining proper safety standards

Directing certain office personnel to work remotely, efficiently and safely

- Maintaining ongoing relationships and business with existing customers and vendors in the supply chain

As  of  the  date  of  this  filing,  we  have  activated  our  contingency  plans.  We  have  deployed  national  and  regional  teams  to  monitor  the
rapidly evolving situation and recommend risk mitigation actions; we have implemented travel restrictions; and we are following social
distancing practices. We are endeavoring to follow guidance from authorities and health officials including, but not limited to, requiring
associates to wear masks and other protective clothing as appropriate, and implementing additional cleaning and sanitization routines at
system facilities.

During  times  of  crisis,  business  continuity  and  adapting  to  the  needs  of  our  customers  is  critical.  We  have  developed  systemwide
knowledge-sharing routines and processes which include the management of any supply chain challenges. As of the date of this filing,
there has been no material impact on our ability to procure or distribute our products and services. We are moving with speed to best
serve our customers impacted by COVID-19 and to ensure adequate inventory levels in key channels. We have shifted to more remote
and paperless options for customer payments and receipts, including ACH payments.

Critical Accounting Estimates

The  Company's  discussion  and  analysis  of  its  financial  condition  and  results  of  operations  are  based  upon  its  consolidated  financial
statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation
of these consolidated financial statements requires the Company to make estimates and judgments that affect the reported amounts of
assets, liabilities, revenues and expenses and related disclosure of contingent assets and liabilities. Several of the Company's accounting
policies  involve  significant  judgments,  uncertainties  and  estimates.  The  Company  bases  its  estimates  on  historical  experience  and  on
various  other  assumptions  that  are  believed  to  be  reasonable  under  the  circumstances,  the  results  of  which  form  the  basis  for  making
judgments about the carrying values of assets and liabilities. Actual results may differ from these estimates under different assumptions
or conditions. To the extent that actual results differ from management's judgments and estimates, there could be a material adverse effect
on the Company. On a continuous basis, the Company evaluates its estimates, including, but not limited to, those estimates related to its
inventory  reserves,  valuation  allowance  for  the  deferred  tax  assets  relating  to  its  net  operating  loss  carry  forwards  (“NOLs”)  and
goodwill and intangible assets.

Inventory

For inventory, the Company evaluates both current and anticipated sales prices of its products to determine if a write down of inventory
to  net  realizable  value  is  necessary.  Net  realizable  value  represents  the  estimated  selling  price  in  the  ordinary  course  of  business,  less
reasonably  predictable  costs  of  completion  and  disposal.  The  determination  if  a  write-down  to  net  realizable  value  is  necessary  is
primarily  affected  by  the  market  prices  for  the  refrigerant  gases  we  sell.  Commodity  prices  generally  are  affected  by  a  wide  range  of
factors beyond our control, including weather, seasonality, the availability and adequacy of supply, government regulation and policies
and general political and economic conditions. At any time, our inventory levels may be substantial.

Goodwill

The Company has made acquisitions that included a significant amount of goodwill and other intangible assets. The Company applies the
purchase method of accounting for acquisitions, which among other things, requires the recognition of goodwill (which represents the
excess of the purchase price of the acquisition over the fair value of the net assets acquired and identified intangible assets). We test our
goodwill  for  impairment  on  an  annual  basis  (the  first  day  of  the  fourth  quarter)  and  between  annual  tests  if  an  event  occurs  or
circumstances change that would more likely than not reduce the fair value of an asset below its carrying value. Other intangible assets
that meet certain criteria are amortized over their estimated useful lives.

15

Table of Contents

An impairment charge is recorded based on the excess of a reporting unit’s carrying amount over its fair value. An impairment charge
would be recognized when the carrying amount exceeds the estimated fair value of a reporting unit. These impairment evaluations use
many  assumptions  and  estimates  in  determining  an  impairment  loss,  including  certain  assumptions  and  estimates  related  to  future
earnings.  If  the  Company  does  not  achieve  its  earnings  objectives,  the  assumptions  and  estimates  underlying  these  impairment
evaluations could be adversely affected, which could result in an asset impairment charge that would negatively impact operating results.
During  the  fourth  quarter  of  2021,  we  completed  our  annual  impairment  test  as  of  October  1  and  determined  in  our  qualitative
assessment  that  it  is  more  likely  than  not  that  the  fair  value  of  the  reporting  unit  is  greater  than  its  carrying  amount,  resulting  in  no
goodwill impairment. There can be no assurances that future sustained declines in macroeconomic or business conditions affecting our
industry will not occur, which could result in goodwill impairment charges in future periods.

There were no goodwill impairment losses recognized in any of the two years ended December 31, 2021 and 2020.

Other Intangibles

Intangibles with determinable lives are amortized over the estimated useful lives of the assets currently ranging from 6 to 13 years. The
Company reviews these useful lives annually to determine that they reflect future realizable value.

Income Taxes

The Company is taxed at statutory corporate income tax rates after adjusting income reported for financial statement purposes for certain
items.  Current  income  tax  expense  (benefit)  reflects  the  tax  results  of  revenues  and  expenses  currently  taxable  or  deductible.  The
Company utilizes the asset and liability method of accounting for deferred income taxes, which provides for the recognition of deferred
tax assets or liabilities, based on enacted tax rates and laws, for the differences between the financial and income tax reporting bases of
assets and liabilities.

The tax benefit associated with the Company’s net operating loss carry forwards (“NOLs”) is recognized to the extent that the Company
expects  to  realize  future  taxable  income.  As  a  result  of  a  prior  “change  in  control”,  as  defined  by  the  Internal  Revenue  Service,  the
Company’s ability to utilize its existing NOLs is subject to certain annual limitations. To the extent that the Company utilizes its NOLs, it
will not pay tax on such income. However, to the extent that the Company’s net income, if any, exceeds the annual NOL limitation, it
will pay income taxes based on the then existing statutory rates. In addition, certain states either do not allow or limit NOLs and as such
the Company will be liable for certain state income taxes.

As of December 31, 2021, the Company had NOLs of approximately $29.3 million, none of which have an expiration date and which are
subject to annual limitations of 80% of tax earnings. As of December 31, 2021, the Company had state tax NOLs of approximately $21.0
million expiring in various years. We review the likelihood that we will realize the benefit of our deferred tax assets, and therefore the
need for valuation allowances, on an annual basis in the fourth quarter of the year, and more frequently if events indicate that a review is
required. In determining the requirement for a valuation allowance, the historical and projected financial results are considered, along
with all other available positive and negative evidence.

Concluding  that  a  valuation  allowance  is  not  required  is  difficult  when  there  is  significant  negative  evidence  that  is  objective  and
verifiable, such as cumulative losses in recent years. We utilize a rolling twelve quarters of pre-tax income or loss adjusted for significant
permanent book to tax differences, as well as non-recurring items, as a measure of our cumulative results in recent years. Based on our
assessment as of December 31, 2019, 2020 and 2021, we concluded that due to the uncertainty that the deferred tax assets will not be
fully realized in the future, we recorded a valuation allowance of approximately $11.3 million during 2018, and due to additional losses,
increased the valuation allowance through 2019 and 2020 to $19.0 million. For the year ended December 31,  2021, and due to additional
income    that  resulted  in  the  utilization  of  net  operating  losses  of  $16.8  million,  we  reduced  the  valuation  allowance  by  $3.9  million
resulting in an ending balance of $15.1 million as of December 31, 2021.

The Company evaluates uncertain tax positions, if any, by determining if it is more likely than not to be sustained upon examination by
the taxing authorities. As of December 31, 2021 and December 31, 2020, the Company believes it had no uncertain tax positions and
there are no open federal or state examinations.

Overview

The  Company  is  a  leading  provider  of  sustainable  refrigerant  products  and  services  to  the  Heating  Ventilation  Air  Conditioning  and
Refrigeration  (“HVACR”)  industry.  For  nearly  three  decades,  we  have  demonstrated  our  commitment  to  our  customers  and  the
environment by becoming one of the United States’ largest refrigerant reclaimers through multimillion dollar investments in the plants
and advanced separation technology required to recover a wide variety of refrigerants and restoring them to Air-Conditioning, Heating,
and Refrigeration Institute (“AHRI”) standard for reuse as certified EMERALD Refrigerants™.

The Company's products and services are primarily used in commercial air conditioning, industrial processing and refrigeration systems,
and include refrigerant and industrial gas sales, refrigerant management services consisting primarily of reclamation of refrigerants and
RefrigerantSide®  Services  performed  at  a  customer's  site,  consisting  of  system  decontamination  to  remove  moisture,  oils  and  other
contaminants.

Sales of refrigerants continue to represent a significant majority of the Company’s revenues.

The Company also sells industrial gases to a variety of industry customers, predominantly to users in, or involved with, the US Military.
In July 2016, the Company was awarded, as prime contractor, a five-year fixed price contract, including a five-year renewal option which
has  been  exercised,  awarded  to  it  by  the  United  States  Defense  Logistics  Agency  (“DLA”)  for  the  management  and  supply  of
refrigerants,  compressed  gases,  cylinders  and  related  items  to  US  Military  commands  and  installations,  Federal  civilian  agencies  and
foreign militaries. Primary users include the US Army, Navy, Air Force, Marine Corps and Coast Guard. Our contract with DLA expires
in July 2026.

Results of Operations

Year ended December 31, 2021 as compared to the year ended December 31, 2020

Revenues for the year ended December 31, 2021 were $192.7 million, an increase of $45.1 million or 30.6% from the $147.6 million
reported during the comparable 2020 period. The increase was mainly attributable to higher selling prices of certain refrigerants sold,
partially  offset  by  reduced  volume  as  the  Company  was  more  selective  in  its  sales  of  refrigerants.  Starting  in  late  March  2020,  the
COVID-19 virus pandemic negatively impacted our economy, including the closures to public venues, such as office buildings, gyms,
schools and universities across the U.S., which negatively impacted our end markets and overall demand for refrigerants.

Cost of sales for the year ended December 31, 2021 was $121.1 million or 63% of sales. Cost of sales for the year ended December 31,
2020  was  $112.2  million  or  76%  of  sales.  The  reduction  in  the  cost  of  sales  percentage  from  76%  to  63%  is  primarily  due  to  higher
selling prices and lower costs of certain refrigerants sold during the year 2021 when compared to the year 2020.

Selling,  general  and  administrative  (“SG&A”)  expenses  for  the  year  ended  December  31,  2021  were  $26.6  million,  representing  a
negligible variance when compared to $26.6 million reported during the comparable 2020 period.  SG&A mainly consists of professional
fees, payroll costs and other selling, general and administrative expense.

Amortization expense was $2.8 million and 2.9 million during 2021 and 2020, respectively.

Other expense for 2021 was $8.9 million, compared to the $11.3 million of other expense reported during the comparable 2020 period.
 Interest expense was lower due to reduced debt resulting from the Company paying down principal of its term loan debt. Other income
for the year ended December 31, 2021 was $2.5 million related to the forgiveness of the Company’s PPP Loan. Other income for the year
ended December 31, 2020 was $1.0 million relating to the receipt of key man life insurance proceeds from the unexpected passing of
Kevin J. Zugibe, Chairman of the Board and Chief Executive Officer of the Company at that time.

Income tax expense for 2021 was $1.1 million compared to income tax benefit of $0.2 million for 2020. For 2021 and 2020, income tax
expense  for  federal  and  state  income  tax  purposes  was  determined  by  applying  statutory  income  tax  rates  to  pre-tax  income  after
adjusting for certain items. As discussed previously, we concluded that due to the uncertainty that the deferred tax assets will not be fully
realized in the future, we have recorded a full valuation allowance as of December 31, 2021.

Table of Contents

The net income for the year ended December 31, 2021 was $32.3 million, an increase of $37.5 million from the $5.2 million of net loss
reported during the comparable 2020 period, primarily due to higher revenues and reduced interest expense, as described above.

Liquidity and Capital Resources

At December 31, 2021, the Company had working capital, which represents current assets less current liabilities, of $55.5 million, an
increase of $31.1 million from the working capital of $24.4 million at December 31, 2020. The increase in working capital is primarily
attributable to timing of borrowings, accounts receivable and inventory.

Inventory and trade receivables are principal components of current assets. At December 31, 2021, the Company had inventory of $94.1
million, an increase of $49.6 million from $44.5 million at December 31, 2020. The increase in the inventory balance is primarily due to
increases in inventory cost in 2021, consistent with the increase in selling price of certain refrigerants.  The Company’s ability to sell and
replace its inventory on a timely basis and the prices at which it can be sold are subject, among other things, to current market conditions
and the nature of supplier or customer arrangements and the Company’s ability to source CFC and HCFC based refrigerants (which are
no longer being produced) and HFC refrigerants (which are currently in the process of being phased down).

At December 31, 2021, the Company had trade receivables, net of allowance for doubtful accounts, of $14.2 million, an increase of $4.4
million from $9.8 million at December 31, 2020. The Company’s trade receivables are concentrated with various wholesalers, brokers,
contractors and end-users within the refrigeration industry that are primarily located in the continental United States. The Company has
historically financed its working capital requirements through cash flows from operations, the issuance of debt and equity securities, and
bank borrowings.

Net cash used in operating activities for the year ended December 31, 2021 was $1.2 million, a reduction of $12.9 million compared to
the net cash provided by operating activities of $11.7 million for the comparable 2020 period. The variance is primarily due to increased
inventory cost, as previously mentioned, offset by increased net income in 2021, primarily as a result of increased selling price of certain
refrigerants sold.

Net cash used in investing activities for 2021 and 2020 was $1.9 million and $0.5 million, respectively. As described above, key man life
insurance proceeds of $1.0 million during 2020 were offset by capital expenditures incurred in the ordinary course of business, mainly in
our plant facilities.

Net cash provided by financing activities for 2021 was $5.3 million, compared to net cash used in financing activities of $12.5 million
for 2020. The variance is mainly due to borrowings under the revolving credit facility to purchase inventory during 2021.  In 2020, the
Company received $2.5 million under the PPP loan, which was forgiven in 2021.

At December 31, 2021, cash and cash equivalents were $3.5 million, or approximately $2.2 million higher than the $1.3 million of cash
and cash equivalents at December 31, 2020, mainly due to timing and as a result of the transactions mentioned above.

Revolving Credit Facility (prior to refinancing on March 2, 2022)

On  December  19,  2019,  Hudson  Technologies  Company  (“HTC”),  Hudson  Holdings,  Inc.  (“Holdings”)  and  Aspen  Refrigerants,  Inc.
(“ARI”), as borrowers (collectively, the “Borrowers”), and Hudson Technologies, Inc. (the “Company”) as a guarantor, became obligated
under a Credit Agreement (the “Wells Fargo Facility”) with Wells Fargo Bank, as administrative agent and lender (“Agent” or “Wells
Fargo”) and such other lenders as may thereafter become a party to the Wells Fargo Facility. The Wells Fargo Facility was amended and
restated on March 2, 2022 (see “-Revolving Credit Facility Amendment” below).

Under the terms of the Wells Fargo Facility, the Borrowers could borrow, from time to time, up to $60 million at any time consisting of
revolving loans in a maximum amount up to the lesser of $60 million and a borrowing base that was calculated based on the outstanding
amount of the Borrowers’ eligible receivables and eligible inventory, as described in the Wells Fargo Facility. The Wells Fargo Facility
also contained a sublimit of $5 million for swing line loans and $2 million for letters of credit.

Amounts borrowed under the Wells Fargo Facility were used by the Borrowers to repay existing revolving indebtedness under its prior
revolving credit facility, repay certain principal amounts under the Term Loan Facility (as defined below), and for working capital needs,
certain permitted acquisitions, and to reimburse drawings under letters of credit.

18

Table of Contents

Interest on loans under the Wells Fargo Facility was payable in arrears on the first day of each month. Interest charges with respect to
loans were computed on the actual principal amount of loans outstanding during the month at a rate per annum equal to (A) with respect
to Base Rate loans, the sum of (i) a rate per annum equal to the higher of (1) the federal funds rate plus 0.5%, (2) one month LIBOR plus
1.0%,  and  (3)  the  prime  commercial  lending  rate  of  Wells  Fargo,  plus  (ii)  between  1.25%  and  1.75%  depending  on  average  monthly
undrawn availability and (B) with respect to LIBOR rate loans, the sum of the LIBOR rate plus between 2.25% and 2.75% depending on
average monthly undrawn availability.

In connection with the closing of the Wells Fargo Facility, the Company also entered into a Guaranty and Security Agreement, dated as
of  December  19,  2019  (the  “Revolver  Guaranty  and  Security  Agreement”),  pursuant  to  which  the  Company  and  certain  subsidiaries
unconditionally guaranteed the payment and performance of all obligations owing by Borrowers to Wells Fargo, as Agent for the benefit
of  the  revolving  lenders.  Pursuant  to  the  Revolver  Guaranty  and  Security  Agreement,  Borrowers,  the  Company  and  certain  other
subsidiaries  granted  to  the  Agent,  for  the  benefit  of  the  Wells  Fargo  Facility  lenders,  a  security  interest  in  substantially  all  of  their
respective assets, including receivables, equipment, general intangibles (including intellectual property), inventory, subsidiary stock, real
property, and certain other assets. The Revolver Guaranty and Security Agreement also provided that the Agent shall receive the right to
dominion over certain of the Borrowers’ bank accounts in the event of an Event of Default under the Wells Fargo Facility, or if undrawn
availability under the Wells Fargo Facility falls below $9 million at any time.

The Wells Fargo Facility contained a financial covenant requiring the Company to maintain at all times minimum liquidity (defined as
availability under the Wells Fargo Facility plus unrestricted cash) of at least $5 million, of which at least $3 million must be derived from
availability. The Wells Fargo Facility also contained a springing covenant, which took effect only upon a failure to maintain undrawn
availability of at least $7.5 million, requiring the Company to maintain a Fixed Charge Coverage Ratio (FCCR) of not less than 1.00 to
1.00, as of the end of each trailing period of twelve consecutive fiscal months commencing with the month prior to the triggering of the
covenant.  The  FCCR  (as  defined  in  the  Wells  Fargo  Facility)  is  the  ratio  of  (a)  EBITDA  for  such  period,  minus  unfinanced  capital
expenditures made during such period, to (b) the aggregate amount of (i) interest expense required to be paid (other than interest paid-in-
kind,  amortization  of  financing  fees,  and  other  non-cash  interest  expense)  during  such  period,  (ii)  scheduled  principal  payments  (but
excluding principal payments relating to outstanding revolving loans under the Wells Fargo Facility), (iii) all net federal, state, and local
income taxes required to be paid during such period (provided, that any tax refunds received shall be applied to the period in which the
cash outlay for such taxes was made), (iv) all restricted payments paid (as defined in the Wells Fargo Facility) during such period, and
(v) to the extent not otherwise deducted from EBITDA for such period, all payments required to be made during such period in respect of
any funding deficiency or funding shortfall with respect to any pension plan. The FCCR covenant ceases after the Borrowers have been
in compliance therewith for two consecutive months.

The  Wells  Fargo  Facility  also  contained  customary  non-financial  covenants  relating  to  the  Company  and  the  Borrowers,  including
limitations  on  Borrowers’  ability  to  pay  dividends  on  common  stock  or  preferred  stock,  and  also  includes  certain  events  of  default,
including payment defaults, breaches of representations and warranties, covenant defaults, cross-defaults to other obligations, events of
bankruptcy and insolvency, certain ERISA events, judgments in excess of specified amounts, impairments to guarantees and a change of
control. The Wells Fargo Facility also contained certain covenants contained in the Fourth Amendment to the Prior Term Loan Facility
described below.

On April 23, 2020, the Borrowers, the Company and its subsidiaries entered into a First Amendment to Credit Agreement with Wells
Fargo  (the  “First  Amendment”).  The  First  Amendment  authorized  the  Company  and  its  subsidiaries  to  incur  up  to  $2.5  million  of
indebtedness under the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) and contained other provisions relating
to the treatment of such proceeds and any potential debt forgiveness, under the Wells Fargo Facility.

The commitments under the Wells Fargo Facility were to expire and the full outstanding principal amount of the loans, together with
accrued and unpaid interest, would have been due and payable in full on December 19, 2022, unless the commitments were terminated
and the outstanding principal amount of the loans were accelerated sooner following an event of default.

Prior Term Loan Facility (prior to refinancing on March 2, 2022)

On  October  10,  2017,  HTC,  Holdings,  and  ARI,  as  borrowers,  and  the  Company,  as  guarantor,  became  obligated  under  a  Term  Loan
Credit  and  Security  Agreement  (as  amended,  the  “Prior  Term  Loan  Facility”)  with  U.S.  Bank  National  Association,  as  administrative
agent and collateral agent (“Prior Term Loan Agent”) and funds advised by FS Investments and such other lenders as may thereafter

Table of Contents

become  a  party  to  the  Term  Loan  Facility  (the  “Prior  Term  Loan  Lenders”).  The  Prior  Term  Loan  Facility  was  repaid  in  full  and
terminated on March 2, 2022 (see “-Termination of Prior Term Loan Facility” below).

Under the terms of the Prior Term Loan Facility, the Borrowers immediately borrowed $105 million pursuant to a term loan (the “Prior
Term Loan”).

The Prior Term Loan was to mature on October 10, 2023. Interest on the Prior Term Loan was generally payable on the earlier of the last
day of the interest period applicable to such Eurodollar rate loan and the last day of the Term Loan Facility, as applicable. Interest is
payable at the rate per annum of the Eurodollar Rate (as defined in the Term Loan Facility) plus 10.25%. The Borrowers had the option
of paying 3.00% interest per annum in kind by adding such amount to the principal of the Prior Term Loans during no more than five
fiscal quarters during the term of the Prior Term Loan Facility.

Borrowers and the Company granted to the Prior Term Loan Agent, for the benefit of the Prior Term Loan Lenders, a security interest in
substantially  all  of  their  respective  assets,  including  receivables,  equipment,  general  intangibles  (including  intellectual  property),
inventory, subsidiary stock, real property, and certain other assets.

The Prior Term Loan Facility contained a financial covenant requiring the Company to maintain a specified total leverage ratio (“TLR”),
tested as of the last day of the fiscal quarter. The TLR (as defined in the Prior Term Loan Facility) is the ratio of (a) funded debt as of
such day to (b) EBITDA for the four consecutive fiscal quarters ending on the last day of such fiscal quarter. Funded debt (as defined in
the  Prior  Term  Loan  Facility)  includes  amounts  borrowed  under  the  Wells  Fargo  Facility  and  the  Term  Loan  Facility  as  well  as
capitalized lease obligations and other indebtedness for borrowed money maturing more than one year from the date of creation thereof.
As of December 31, 2021 and 2020, the TLR was approximately 1.93 to 1 and 5.84 to 1, respectively.

The Prior Term Loan Facility also contained customary non-financial covenants relating to the Company and the Borrowers, including
limitations on their ability to pay dividends on common stock or preferred stock, and also included certain events of default, including
payment defaults, breaches of representations and warranties, covenant defaults, cross-defaults to other obligations, events of bankruptcy
and insolvency, certain ERISA events, judgments in excess of specified amounts, impairments to guarantees and a change of control.

In connection with the closing of the Prior Term Loan Facility, the Company also entered into a Guaranty and Suretyship Agreement,
dated as of October 10, 2017 (the “Prior Term Loan Guarantee”), pursuant to which the Company affirmed its unconditional guarantee of
the payment and performance of all obligations owing by Borrowers to Prior Term Loan Agent, as agent for the benefit of the Prior Term
Loan Lenders.

The  Prior  Term  Loan  Agent  and  the  Agent  entered  into  an  intercreditor  agreement  governing  the  relative  priority  of  their  security
interests  granted  by  the  Borrowers  and  the  Guarantor  in  the  collateral,  providing  that  the  Agent  would  have  a  first  priority  security
interest in the accounts receivable, inventory, deposit accounts and certain other assets (the “Revolving Credit Priority Collateral”) and
the Term Loan Agent would have a first priority security interest in the equipment, real property, capital stock of subsidiaries and certain
other assets (the “Prior Term Loan Priority Collateral”).

On  December  19,  2019,  HTC,  Holdings  and  ARI  as  borrowers  and  the  Company  as  a  guarantor,  entered  into  a  Waiver  and  Fourth
Amendment to Term Loan Credit and Security Agreement (the “Fourth Amendment”) with U.S. Bank National Association, as collateral
agent and administrative agent, and the various lenders thereunder.

The Fourth Amendment waived financial covenant defaults at June 30, 2019 and September 30, 2019 and amended the Term Loan Credit
and Security Agreement dated October 10, 2017 (as previously amended, the “Prior Term Loan Facility”) to reset the maximum Total
Leverage Ratio covenant contained in the Prior Term Loan Facility at the indicated dates as follows: (i) September 30, 2019 - 15.67:1.00;
(ii)  December  31,  2019  –  14.54:1.00;  (iii)  March  31,  2020  –  16.57:1.00;  (iv)  June  30,  2020  –  10.87:1.00;  (v)  September  30,  2020  –
8.89:1.00; (vi) December 31, 2020 – 8.89:1.00; (vii) March 31, 2021 – 7.75:1.00; (viii) June 30, 2021 – 7.03:1.00; (ix) September 30,
2021  –  6.08:1.00;  and  (x)  December  31,  2021  –  5.36:1.00.  The  Fourth  Amendment  also  reset  the  minimum  liquidity  requirement
(consisting of cash plus undrawn availability on the Borrowers’ revolving loan facility) of $5 million, measured monthly. Furthermore,
the Fourth Amendment added a minimum LTM Adjusted EBITDA covenant as of the indicated dates as follows: (i) September 30, 2019
- $7.887 million; (ii) December 31, 2019 – $7.954 million; (iii) March 31, 2020 – $7.359 million; (iv) June 30, 2020 – $11.745 million;
(v) September 30, 2020 – $12.021 million; (vi) December 31, 2020 – $12.300 million; (vii) March 31, 2021 –

20

Table of Contents

$14.295  million;  (viii)  June  30,  2021  –  $14.566  million;  (ix)  September  30,  2021  –  $15.431  million;  and  (x)  December  31,  2021  –
$16.267 million.

The  Fourth  Amendment  also  (i)  continued  the  limitation  on  acquisitions  and  dividends,  (ii)  required  a  principal  repayment  of
$14,000,000  upon  execution  of  the  Fourth  Amendment  and  (iii)  increased  the  scheduled  quarterly  principal  repayments  to  $562,000
effective March 31, 2020 and $1,312,000 effective December 31, 2020.

The Fourth Amendment also terminated the exit fee payable to the term loan lenders, which would have been payable in full in cash
upon the earlier to occur of (x) repayment in full of the term loans, or (y) any acceleration of the term loans. In lieu of the exit fee, the
Fourth  Amendment  reinstated  a  prepayment  premium  equal  to  the  following  percentages  of  the  principal  amount  prepaid,  depending
upon  the  date  of  prepayment:  (i)  through  March  31,  2020  –  0.50%;  (ii)  from  April  1,  2020  through  March  31,  2021  –  2.50%;  and
(iii) from April 1, 2021 and thereafter – 5.00%.

The Fourth Amendment also added a new covenant providing that in the event of a breach of a financial covenant contained in the Term
Loan Facility or any failure to make a required principal repayment (a “Trigger Event”), then on or prior to six months after a Trigger
Event, the Company shall commence a process to (x) sell its businesses and/or assets, and/or (y) consummate a refinancing transaction
with respect to the Term Loan Facility (a “Transaction”), in each case, subject to enumerated time milestones contained in the Fourth
Amendment, and which requires that Transaction shall, in any event, be consummated on or prior to the eighteen (18) month anniversary
of the Trigger Event.

As closing conditions to the execution and delivery of the Fourth Amendment, the Company was required to: (i) amend its Bylaws in a
manner acceptable to the Term Loan Facility lenders; (ii) appoint two new independent directors to the board of directors (the “Special
Directors”); and (iii) pay an amendment fee of 0.50% of the amount of the outstanding loans under the Term Loan Facility.

On April 23, 2020, HTC, Holdings and ARI as borrowers and the Company as a guarantor, entered into a Fifth Amendment to Term
Loan  Credit  and  Security  Agreement  (the  “Fifth  Amendment”)  with  U.S.  Bank  National  Association,  as  collateral  agent  and
administrative agent, and the various lenders thereunder. The Fifth Amendment authorized the Company and its subsidiaries to incur up
to $2.5 million of indebtedness under the CARES Act and contained other provisions relating to the treatment of such proceeds and any
potential debt forgiveness, under the Prior Term Loan Facility.

The  Company  evaluated  the  Fourth  and  Fifth  Amendments  in  accordance  with  the  provisions  of  Accounting  Standards  Codification
(“ASC”)  470,  Debt,  to  determine  if  the  Amendments  were  (1)  a  troubled  debt  restructuring,  and  if  not,  (2)  a  modification  or  an
extinguishment of debt. The Company concluded that the Fourth Amendment was a troubled debt restructuring for accounting purposes
due to the removal of the exit fee; as such, the Company capitalized an additional $0.5 million of deferred financing costs, which are
being amortized over the remaining term. The future undiscounted cash flows of the term loan, as amended, exceeded the carrying value,
and accordingly, no gain was recognized and no adjustment was made to the carrying value of the debt.

The Company was in compliance with all covenants, under the Wells Fargo Facility and the Prior Term Loan Facility, as amended, as of
December 31, 2021.

New Term Loan Facility (Effective March 2, 2022)

On March 2, 2022, Hudson Technologies Company (“HTC”), an indirect subsidiary of Hudson Technologies, Inc. (the “Company”), and
the Company’s subsidiary Hudson Holdings, Inc., as borrowers (collectively, the “Borrowers”), and the Company, as guarantor, became
obligated under a Credit Agreement (the “Term Loan Facility”) with TCW Asset Management Company LLC, as administrative agent
(“Term Loan Agent”) and the lender parties thereto (the “Term Loan Lenders”).

Under the terms of the Term Loan Facility, the Borrowers have immediately borrowed $85 million pursuant to a term loan (the “Term
Loan”).  Amounts borrowed under the Term Loan Facility were used by the Borrowers to repay the outstanding principal amount and
related fees and expenses under the Prior Term Loan Facility (as defined below) and for other corporate purposes.

The Term Loan matures on March 2, 2027, or earlier upon certain acceleration or cross default events. Principal payments on the Term
Loan  are  required  on  a  quarterly  basis,  commencing  with  the  quarter  ending  March  31,  2022,  in  the  amount  of  5%  of  the  original
principal amount of the outstanding Term Loan per annum. The Term Loan Facility also requires annual payments of 50% of Excess

21

Table of Contents

Cash Flow (as defined in the Term Loan Facility); provided that commencing with the year ending December 31, 2023 such payments
may be reduced depending upon the Company’s leverage ratio (as defined in the Term Loan Facility) for the applicable year. The Term
Loan Facility also requires mandatory prepayments of the Term Loans in the event of certain asset dispositions, debt issuances, and other
events. The Term Loan may be prepaid at the option of the Borrowers subject to a prepayment premium of 3% in year one, 2% in year
two, 1% in year three, and zero in year four and thereafter.

Interest on the Term Loan is generally payable monthly, in arrears.  Interest charges with respect to the Term Loan are computed on the
actual principal amount of the Term Loan outstanding at a rate per annum equal to (A) with respect to Base Rate loans, the sum of (i) a
rate per annum equal to the higher of (1) 2.0%, (2) the federal funds rate plus 0.5%, (3) one month term SOFR plus 1.0%, and (4) the
prime commercial lending rate quoted by The Wall Street Journal, plus (ii) between 6.0% and 7.0% depending on the applicable leverage
ratio and (B) with respect to SOFR loans, the sum of the applicable SOFR rate plus between 7.0% and 8.0% depending on the applicable
leverage ratio.

Borrowers  and  the  Company  granted  to  the  Term  Loan  Agent,  for  the  benefit  of  the  Term  Loan  Lenders,  a  security  interest  in
substantially  all  of  their  respective  assets,  including  receivables,  equipment,  general  intangibles  (including  intellectual  property),
inventory, subsidiary stock, real property, and certain other assets.

The Term Loan Facility contains a fixed charge coverage ratio covenant and a leverage ratio covenant, each tested quarterly. The Term
Loan  Facility  also  contains  customary  non-financial  covenants  relating  to  the  Company  and  the  Borrowers,  including  limitations  on
Borrowers’ ability to pay dividends on common stock or preferred stock, and also includes certain events of default, including payment
defaults,  breaches  of  representations  and  warranties,  covenant  defaults,  cross-defaults  to  other  obligations,  events  of  bankruptcy  and
insolvency, certain ERISA events, judgments in excess of specified amounts, impairments to guarantees and a change of control.

In connection with the closing of the Term Loan Facility, the Company also entered into a Guaranty and Security Agreement, dated as of
March 2, 2022 (the “Term Loan Guarantee”), pursuant to which the Company affirmed its unconditional guarantee of the payment and
performance of all obligations owing by Borrowers to Term Loan Agent, as agent for the benefit of the Term Loan Lenders.

The Term Loan Agent and the Agent (as defined below) have entered into an intercreditor agreement governing the relative priority of
their security interests granted by the Borrowers and the Guarantor in the collateral, providing that the Agent shall have a first priority
security  interest  in  the  accounts  receivable,  inventory,  deposit  accounts  and  certain  other  assets  (the  “Revolving  Credit  Priority
Collateral”)  and  the  Term  Loan  Agent  shall  have  a  first  priority  security  interest  in  the  equipment,  real  property,  capital  stock  of
subsidiaries and certain other assets (the “Term Loan Priority Collateral”).

Termination of Prior Term Loan Facility

In conjunction with entry into the new Term Loan Facility as described above, on March 2, 2022 the Company's existing term loans set
forth in the Term Loan Credit and Security Agreement with U.S. Bank National Association, as collateral agent and administrative agent,
and the various lenders thereunder, as amended (the “Prior Term Loan Facility”), which had a principal balance of approximately $63.9
million after payment of a $16.0 million excess cash flow amount thereunder, was repaid in full, together with associated required lender
fees and expenses of $3.3 million, and the Prior Term Loan Facility was terminated.

Revolving Credit Facility Amendment (Effective March 2, 2022)

On March 2, 2022, Hudson Technologies Company (“HTC”) and Hudson Holdings, Inc. (“Holdings”), as borrowers (collectively, the
“Borrowers”), and Hudson Technologies, Inc (the “Company”) as a guarantor, entered into an Amended and Restated Credit Agreement
(the  “Amended  Wells  Fargo  Facility”)  with  Wells  Fargo  Bank,  National  Association,  as  administrative  agent  and  lender  (“Agent”  or
“Wells Fargo”) and such other lenders as have or may thereafter become a party to the Wells Fargo Facility. The Amended Wells Fargo
facility amended and restated the prior Wells Fargo Facility.

Under  the  terms  of  the  Amended  Wells  Fargo  Facility,  the  Borrowers  may  borrow  up  to  $90  million  consisting  of:  (i)  $15  million
immediately borrowed in the form of a “first in last out” term loan (the “FILO Tranche”) and (ii) from time to time, up to $75 million at
any time consisting of revolving loans (the “Revolving Loans”) in a maximum amount up to the lesser of $75 million and a borrowing
base that is calculated based on the outstanding amount of the Borrowers’ eligible receivables and eligible inventory, as described in the

22

Table of Contents

Amended Wells Fargo Facility. The Amended Wells Fargo Facility also contains a sublimit of $9 million for swing line loans and $2
million for letters of credit.

Amounts borrowed under the Amended Wells Fargo Facility may be used for working capital needs, certain permitted acquisitions, and
to reimburse drawings under letters of credit.

Interest under the Amended Wells Fargo Facility is payable in arrears on the first day of each month. Interest charges with respect to
Revolving Loans are computed on the actual principal amount of Revolving Loans outstanding at a rate per annum equal to (A) with
respect to Base Rate loans, the sum of (i) a rate per annum equal to the higher of (1) 1.0%, (2) the federal funds rate plus 0.5%, (3) one
month term SOFR plus 1.0%, and (4) the prime commercial lending rate of Wells Fargo, plus (ii) between 1.25% and 1.75% depending
on average monthly undrawn availability and (B) with respect to SOFR loans, the sum of the applicable SOFR rate plus between 2.36%
and 2.86% depending on average quarterly undrawn availability.  Interest charges with respect to the FILO Tranche are computed on the
actual principal amount of FILO Tranche loans outstanding at a rate per annum equal to (A) with respect to Base Rate FILO Tranche
loans, the sum of (i) a rate per annum equal to the higher of (1) 1.0%, (2) the federal funds rate plus 0.5%, (3) one month term SOFR plus
1.0%, and (4) the prime commercial lending rate of Wells Fargo, plus (ii) 6.5% and (B) with respect to SOFR FILO Tranche loans, the
sum of the applicable SOFR rate plus 7.50%.

In connection with the closing of the Amended Wells Fargo Facility, the Company also entered into a First Amendment to Guaranty and
Security  Agreement,  dated  as  of  March  2,  2022  (the  “Amended  Revolver  Guaranty  and  Security  Agreement”),  pursuant  to  which  the
Company and certain subsidiaries are continuing to unconditionally guarantee the payment and performance of all obligations owing by
Borrowers to Wells Fargo, as Agent for the benefit of the revolving lenders. Pursuant to the Revolver Guaranty and Security Agreement,
as amended, Borrowers, the Company and certain other subsidiaries are continuing to grant to the Agent, for the benefit of the Wells
Fargo  Facility  lenders,  a  security  interest  in  substantially  all  of  their  respective  assets,  including  receivables,  equipment,  general
intangibles (including intellectual property), inventory, subsidiary stock, real property, and certain other assets.

The  Amended  Wells  Fargo  Facility  contains  a  financial  covenant  requiring  the  Company  to  maintain  at  all  times  minimum  liquidity
(defined as availability under the Amended Wells Fargo Facility plus unrestricted cash) of at least $5 million, of which at least $3 million
must be derived from availability. The Amended Wells Fargo Facility also contains a springing covenant, which takes effect only upon a
failure  to  maintain  undrawn  availability  of  at  least  $11.25  million  or  upon  an  election  by  the  Borrowers  to  increase  the  inventory
component of the borrowing base, requiring the Company to maintain a Fixed Charge Coverage Ratio (FCCR) of not less than 1.00 to
1.00,  as  of  the  end  of  each  trailing  period  of  twelve  consecutive  months  commencing  with  the  month  prior  to  the  triggering  of  the
covenant.  The  FCCR  (as  defined  in  the  Wells  Fargo  Facility)  is  the  ratio  of  (a)  EBITDA  for  such  period,  minus  unfinanced  capital
expenditures made during such period, to (b) the aggregate amount of (i) interest expense required to be paid (other than interest paid-in-
kind,  amortization  of  financing  fees,  and  other  non-cash  interest  expense)  during  such  period,  (ii)  scheduled  principal  payments  (but
excluding  principal  payments  relating  to  outstanding  Revolving  Loans  under  the  Amended  Wells  Fargo  Facility),  (iii)  all  net  federal,
state, and local income taxes required to be paid during such period (provided, that any tax refunds received shall be applied to the period
in which the cash outlay for such taxes was made), (iv) all restricted payments paid (as defined in the Amended Wells Fargo Facility)
during such period, and (v) to the extent not otherwise deducted from EBITDA for such period, all payments required to be made during
such period in respect of any funding deficiency or funding shortfall with respect to any pension plan. The FCCR covenant ceases after
the Borrowers have been in compliance therewith for two consecutive months.

The  Amended  Wells  Fargo  Facility  also  contains  customary  non-financial  covenants  relating  to  the  Company  and  the  Borrowers,
including  limitations  on  Borrowers’  ability  to  pay  dividends  on  common  stock  or  preferred  stock,  and  also  includes  certain  events  of
default,  including  payment  defaults,  breaches  of  representations  and  warranties,  covenant  defaults,  cross-defaults  to  other  obligations,
events of bankruptcy and insolvency, certain ERISA events, judgments in excess of specified amounts, impairments to guarantees and a
change of control.

The commitments under the Wells Fargo Facility will expire and the full outstanding principal amount of the loans, together with accrued
and unpaid interest, are due and payable in full on March 2, 2027, unless the commitments are terminated and the outstanding principal
amount of the loans are accelerated sooner following an event of default or in the event of certain other cross-defaults.

The  Company’s  ability  to  comply  with  these  covenants  in  future  quarters  may  be  affected  by  events  beyond  the  Company’s  control,
including general economic conditions, weather conditions, regulations and refrigerant pricing. Therefore, we cannot make any assurance
that we will continue to be in compliance during future periods.

Table of Contents

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

CARES Act Loan

On April 23, 2020 the Company received a loan in the amount of $2.475 million from Meridian Bank under the Paycheck Protection
Program (“PPP”) pursuant to the CARES Act. The loan had a term of two years, was unsecured, and bore interest at a fixed rate of one
percent per annum, with the first nine months of principal and interest deferred. As a result of the COVID-19 pandemic, in applying for
the  loan  the  Company  made  a  good  faith  assertion  based  upon  the  degree  of  uncertainty  introduced  to  the  capital  markets  and  the
industries affecting the Company's customers and the Company's dependency to curtail expenses to fund ongoing operations.  The PPP
loan proceeds have been used in part to help offset payroll costs as stipulated in the legislation. All or a portion of the PPP loan may be
forgiven by the U.S. Small Business Administration (“SBA”) upon application by the Company and upon documentation of expenditures
in accordance with the SBA requirements. Under the CARES Act, loan forgiveness is available for the sum of documented payroll costs
and  other  covered  areas,  such  as  rent  payments,  mortgage  interest  and  utilities,  as  applicable.  During  the  third  quarter  of  2021,  the
Company  received  forgiveness  of  the  loan  from  the  SBA,  resulting  in  $2.475  million  of  Other  Income  recorded  in  the  Company’s
Consolidated Statements of Operations.

Off-Balance Sheet Arrangements

None.

Inflation

Inflation, historically or the current rise, has not had a material impact on the Company's operations.

Reliance on Suppliers and Customers

The Company participates in an industry that is highly regulated, and changes in the regulations affecting our business could affect our
operating  results.  Currently  the  Company  purchases  virgin  HCFC  and  HFC  refrigerants  and  reclaimable,  primarily  HCFC  and  CFC,
refrigerants from suppliers and its customers. Under the Act the phase-down of future production of certain virgin HCFC refrigerants
commenced in 2010 and has been fully phased out by the year 2020, and production of all virgin HCFC refrigerants is scheduled to be
phased out by the year 2030. To the extent that the Company is unable to source sufficient quantities of refrigerants or is unable to obtain
refrigerants on commercially reasonable terms or experiences a decline in demand and/or price for refrigerants sold by it, the Company
could realize reductions in revenue from refrigerant sales, which could have a material adverse effect on the Company’s operating results
and financial position.

For the year ended December 31, 2021, one customer accounted for 10% of the Company’s revenues; no other customer accounted for
more  than  10%  of  the  Company’s  revenues.  At  December  31,  2021,  there  were  $3.1  million  of  outstanding  receivables  from  this
customer.  For  the  year  ended  December  31,  2020,  one  customer  accounted  for  14%  of  the  Company’s  revenues;  no  other  customer
accounted for more than 10% of the Company’s revenues. At December 31, 2020, there were $2.9 million of outstanding receivables
from this customer.

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

Seasonality and Weather Conditions 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

24

Table of Contents

technology and regulations, timing in introduction and/or retrofit or replacement of refrigeration equipment, the rate of expansion of the
Company's operations, and by other factors. The Company's business is seasonal in nature with peak sales of refrigerants occurring in the
first nine months of each year. During past years, the seasonal decrease in sales of refrigerants has resulted in losses particularly in the
fourth quarter of the year. In addition, to the extent that there is unseasonably cool weather throughout the spring and summer months,
which would adversely affect the demand for refrigerants, there would be a corresponding negative impact on the Company. Delays or
inability in securing adequate supplies of refrigerants at peak demand periods, lack of refrigerant demand, increased expenses, declining
refrigerant prices and a loss of a principal customer could result in significant losses. There can be no assurance that the foregoing factors
will not occur and result in a material adverse effect on the Company's financial position and significant losses. The Company believes
that to a lesser extent there is a similar seasonal element to RefrigerantSide® Service revenues as refrigerant sales.

Recent Accounting Pronouncements

In June 2016, the FASB issued ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments, which revises guidance for
the  accounting  for  credit  losses  on  financial  instruments  within  its  scope,  and  in  November  2018,  issued  ASU  No.  2018-19  and  in
April 2019, issued ASU No. 2019-04 and in May 2019, issued ASU No. 2019-05, and in November 2019, issued ASU No. 2019-11,
which  each  amended  the  standard.  The  new  standard  introduces  an  approach,  based  on  expected  losses,  to  estimate  credit  losses  on
certain  types  of  financial  instruments  and  modifies  the  impairment  model  for  available-for-sale  debt  securities.  The  new  approach  to
estimating credit losses (referred to as the current expected credit losses model) applies to most financial assets measured at amortized
cost and certain other instruments, including trade and other receivables, loans, held-to-maturity debt securities, net investments in leases
and  off-balance-sheet  credit  exposures.  This  ASU  is  effective  for  fiscal  years  beginning  after  December  15,  2022,  including  interim
periods within those fiscal years, with early adoption permitted. Entities are required to apply the standard’s provisions as a cumulative-
effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is adopted. The Company is
still evaluating the impact of this ASU.

In  March  2020,  the  FASB  issued  ASU  2020-04,  which  provides  relief  from  accounting  analysis  and  impacts  that  may  otherwise  be
required  for  modifications  to  agreements  necessitated  by  reference  rate  reform.  It  also  provides  optional  expedients  to  enable  the
continuance of hedge accounting where certain hedging relationships are impacted by reference rate reform. This optional guidance is
effective immediately, and available to be used through December 31, 2022. We are assessing the impact that reference rate reform and
the related adoption of this guidance will have on our financial statements.

In August 2020, the FASB issued ASU 2020-06, "Debt-Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and
Hedging-Contracts in Entity's Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity's Own
Equity",  which  is  intended  to  simplify  the  accounting  for  convertible  instruments  by  removing  certain  separation  models  in  Subtopic
470-20, Debt-Debt with Conversion and Other Options, for convertible instruments. The pronouncement is effective for fiscal years, and
for  interim  periods  within  those  fiscal  years,  beginning  after  December  15,  2021,  with  early  adoption  permitted.  ASU  2020-06  is  not
expected to have a material impact on our financial statements.

Item 7A. Quantitative and Qualitative Disclosures about Market Risk

Interest Rate Sensitivity

We are exposed to market risk from fluctuations in interest rates on the Wells Fargo Facility and on the Term Loan Facility. The Wells
Fargo Facility was a $60,000,000 secured facility, and the Term Loan Facility provided for Term Loans of $79,866,500 as of December
31, 2021. Effective March 2, 2022, the amended Wells Fargo Facility increased to a $90,000,000 secured facility, while the  Prior Term
Loan Facility was replaced with a Term Loan Facility of $85,000,000.

There was a $15,000,000 outstanding balance on the Wells Fargo Facility as of December 31, 2021. Future interest rate changes on our
borrowing under the Amended Wells Fargo Facility may have an impact on our consolidated results of operations.

There was a $79,866,500 outstanding balance on the Prior Term Loan Facility as of December 31, 2021. Future interest rate changes on
our borrowing under the Term Loans may have an impact on our consolidated results of operations.

If  the  loan  bearing  interest  rate  changed  by  1%,  the  annual  effect  on  interest  expense  would  be  approximately  $0.9  million  as  of
December 31, 2021.

Refrigerant Market

We are also exposed to market risk from fluctuations in the demand, price and availability of refrigerants. To the extent that the Company
is  unable  to  source  sufficient  quantities  of  refrigerants  or  is  unable  to  obtain  refrigerants  on  commercially  reasonable  terms,  or
experiences a decline in demand and/or price for refrigerants sold by the Company, the Company could realize reductions in revenue
from refrigerant sales or write downs of inventory, which could have a material adverse effect on our consolidated results of operations.

Item 9A. Controls and Procedures

Disclosure Controls and Procedures

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

Changes in Internal Control over Financial Reporting

As  required  by  Rule  13a-15(d)  of  the  Exchange  Act,  our  management,  including  our  principal  executive  officer  and  our  principal
financial  officer,  conducted  an  evaluation  of  the  internal  control  over  financial  reporting  to  determine  whether  any  changes  occurred
during  the  quarter  ended  December  31,  2021  that  have  materially  affected,  or  are  reasonably  likely  to  materially  affect,  our  internal
control over financial reporting. Based on that evaluation, our principal executive officer and principal financial officer concluded there
were no such changes.

Management’s Report on Internal Control over Financial Reporting

Management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting for the
Company as defined in Rule 13a-15(f) under the Exchange Act. The Company’s internal control over financial reporting is designed to
provide  reasonable  assurance  to  the  Company’s  management  and  board  of  directors  regarding  the  preparation  and  fair  presentation  of
published financial statements and the reliability of financial reporting.

Because  of  its  inherent  limitations,  internal  control  over  financial  reporting  may  not  prevent  or  detect  misstatements.  Therefore,  even
those  systems  determined  to  be  effective  can  provide  only  reasonable  assurance  with  respect  to  financial  statement  preparation  and
presentation.

The Company’s Chief Executive Officer and Chief Financial Officer have assessed the effectiveness of the Company’s internal control
over financial reporting as of December 31, 2021. In making this assessment, the Company’s Chief Executive Officer and Chief

26

Table of Contents

Financial Officer have used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”)
in  Internal  Control  –  Integrated  Framework  (2013).  Based  on  our  assessment,  the  Company’s  Chief  Executive  Officer  and  Chief
Financial Officer believe that, as of December 31, 2021, the Company’s internal control over financial reporting is effective based on
those criteria.

BDO  USA,  LLP,  the  independent  registered  public  accounting  firm  which  audits  our  financial  statements,  has  provided  an  attestation

Opinion on Internal Control over Financial Reporting

We have audited Hudson Technologies, Inc. and subsidiaries’ (the “Company’s”) internal control over financial reporting as of December
31,  2021,  based  on  criteria  established  in  Internal  Control  –  Integrated  Framework  (2013)  issued  by  the  Committee  of  Sponsoring
Organizations  of  the  Treadway  Commission  (the  “COSO  criteria”).  In  our  opinion,  the  Company  maintained,  in  all  material  respects,
effective internal control over financial reporting as of December 31, 2021, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”),
the consolidated balance sheets of the Company and subsidiaries as of December 31, 2021 and 2020, the related consolidated statements
of operations, stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2021, and the related
notes and our report dated March 24, 2022 expressed an unqualified opinion.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of
the effectiveness of internal control over financial reporting, included in the accompanying Item 9A, Management’s Report on Internal
Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting
based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the
Company  in  accordance  with  U.S.  federal  securities  laws  and  the  applicable  rules  and  regulations  of  the  Securities  and  Exchange
Commission and the PCAOB.

We  conducted  our  audit  of  internal  control  over  financial  reporting  in  accordance  with  the  standards  of  the  PCAOB.  Those  standards
require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting
was  maintained  in  all  material  respects.  Our  audit  included  obtaining  an  understanding  of  internal  control  over  financial  reporting,
assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control
based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances.
We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of
financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting
principles.  A  company’s  internal  control  over  financial  reporting  includes  those  policies  and  procedures  that  (1)  pertain  to  the
maintenance  of  records  that,  in  reasonable  detail,  accurately  and  fairly  reflect  the  transactions  and  dispositions  of  the  assets  of  the
company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in
accordance  with  generally  accepted  accounting  principles,  and  that  receipts  and  expenditures  of  the  company  are  being  made  only  in
accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention
or  timely  detection  of  unauthorized  acquisition,  use,  or  disposition  of  the  company’s  assets  that  could  have  a  material  effect  on  the
financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of
any  evaluation  of  effectiveness  to  future  periods  are  subject  to  the  risk  that  controls  may  become  inadequate  because  of  changes  in
conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Hudson Technologies, Inc. (the “Company”) as of December 31, 2021
and 2020, the related consolidated statements of operations, stockholders’ equity, and cash flows for each of the two years in the period
ended December 31, 2021, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the
consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2021 and
2020, and the results of its operations and its cash flows for each of the two years in the period ended December 31, 2021, in conformity
with accounting principles generally accepted in the United States of America.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”),
the  Company's  internal  control  over  financial  reporting  as  of  December  31,  2021,  based  on  criteria  established  in  Internal  Control  –
Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) and our
report dated March 24, 2022 expressed an unqualified opinion.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion
on  the  Company’s  consolidated  financial  statements  based  on  our  audits.  We  are  a  public  accounting  firm  registered  with  the  Public
Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in
accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and
the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error
or fraud.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether
due  to  error  or  fraud,  and  performing  procedures  that  respond  to  those  risks.  Such  procedures  included  examining,  on  a  test  basis,
evidence  regarding  the  amounts  and  disclosures  in  the  consolidated  financial  statements.  Our  audits  also  included  evaluating  the
accounting  principles  used  and  significant  estimates  made  by  management,  as  well  as  evaluating  the  overall  presentation  of  the
consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements
that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are
material  to  the  consolidated  financial  statements  and  (2)  involved  our  especially  challenging,  subjective,  or  complex  judgments.  The
communication of critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole,
and  we  are  not,  by  communicating  the  critical  audit  matter  below,  providing  separate  opinions  on  the  critical  audit  matter  or  on  the
accounts or disclosures to which it relates.

Goodwill Impairment Assessment

As described in Note 1 and 8 to the Company’s consolidated financial statements, the Company’s goodwill balance as of December 31,
2021 was $47.8 million. Goodwill is tested for impairment at the reporting unit level. The Company has one reporting unit at December
31, 2021. The Company performs an annual impairment test of goodwill on a qualitative or quantitative basis (the first day of the fourth

36

Table of Contents

quarter) and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of an
asset below its carrying value. During the fourth quarter of 2021, the Company completed its annual impairment test as of October 1 and
determined in their qualitative assessment that it is more likely than not that the fair value of the only reporting unit is greater than its
carrying amount, resulting in no goodwill impairment. The qualitative assessment requires management to make assumptions related to
macroeconomic  or  business  conditions  affecting  the  industry.  Changes  in  these  assumptions  could  have  a  significant  impact  on  the
impairment evaluation and could result in goodwill impairment charges.

We  identified  the  evaluation  of  goodwill  impairment  qualitative  assessment  as  a  critical  audit  matter.  Auditing  the  reasonableness  of
management’s assumptions required a high degree of auditor judgment and an increased effort due to the nature and extent required in
evaluating the qualitative assessment.

The primary procedures we performed to address this critical audit matter included:

● Evaluating  the  Company's  impairment  assessment  for  its  reporting  unit  by  considering  the  appropriateness  of  the
macroeconomic,  industry,  market  factors  and  other  entity-specific  events  identified  by  the  Company  against  other  evidence
obtained through other procedures.

● Evaluating management's qualitative assessments by (i) analyzing financial performance of the reporting unit, (ii) recalculating
the  Company's  market  capitalization,  and  (iii)  comparing  actual  financial  performance  with  forecasted  financial  performance
used in previous impairment assessments to evaluate if there were any negative effects on earnings and cash flows that could
impact the analysis.

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, is a refrigerant services company providing
innovative  solutions  to  recurring  problems  within  the  refrigeration  industry.  The  Company’s  operations  consist  of  one  reportable
segment.  The  Company  operates  principally  through  its  wholly-owned  subsidiary,  Hudson  Technologies  Company,  and  Aspen
Refrigerants (“Aspen” or “ARI”), a division of Hudson Technologies Company. Unless the context requires otherwise, references to the
“Company”, “Hudson”, “we”, “us”, “our”, or similar pronouns refer to Hudson Technologies, Inc. and its subsidiaries.

The Company’s products and services are primarily used in commercial air conditioning, industrial processing and refrigeration systems,
and include refrigerant and industrial gas sales, refrigerant management services consisting primarily of reclamation of refrigerants and
RefrigerantSide®  Services  performed  at  a  customer’s  site,  consisting  of  system  decontamination  to  remove  moisture,  oils  and  other
contaminants.

The  Company’s  SmartEnergy  OPS®  service  is  a  web-based  real  time  continuous  monitoring  service  applicable  to  a  facility’s
refrigeration systems and other energy systems. The Company’s Chiller Chemistry® and Chill Smart® services are also predictive and
diagnostic  service  offerings.  As  a  component  of  the  Company’s  products  and  services,  the  Company  also  generates  carbon  offset
projects.

During the year ended December 31, 2020 and continuing through the year ended December 31, 2021, the effects of a novel strain of
coronavirus (“COVID-19”) pandemic and the related actions by governments around the world to attempt to contain the spread of the
virus have materially impacted the global economy. While it is difficult to predict the full scale of the ongoing impact of the COVID-19
outbreak and business disruption, the Company has been taking actions to address the impact of the pandemic, such as working closely
with  our  customers,  reducing  our  expenses  and  monitoring  liquidity.  The  impact  of  the  pandemic  and  the  corresponding  actions  were
reflected into our judgments, assumptions and estimates to prepare the financial statements. As of the date of this filing, there has been
no material impact on our ability to procure or distribute our products and services. However, if the duration of the COVID-19 pandemic
is longer and the operational impact is greater than estimated, the judgments, assumptions and estimates will be updated and could result
in different results in the future.

AIM Act

On September 23, 2021, the United States Environmental Protection Agency (“EPA”) issued the final rule establishing the framework to
allocate allowances for virgin production and consumption of HFCs. The EPA is responsible for the administration of the HFC phase
down enacted by Congress under the AIM Act.

The AIM Act directs the EPA to address the reduction in virgin HFCs and provides authority to do so in three respects:

1) phase down the production and consumption of listed HFCs,
2) manage these HFCs and their substitutes, and
3)

facilitate the transition to next-generation technologies.

Congress also required that EPA shall consider ways to promote reclamation in all phases of its implementation of the AIM Act. The
final rule introduces a stepdown of 10% from baseline levels and a subsequent allowance rule must establish a cumulative 40% reduction
in the baseline for 2024. Hudson received an allocation allowance for calendar year 2022 equal to approximately 3 million Metric Tons
Exchange Value Equivalents, or 1% of the total HFC consumption, with allowances for 2023 and beyond to be determined at a later date.
Reclamation will be critical to maintaining necessary HFC supply levels to ensure an orderly phasedown.

In preparing the accompanying consolidated financial statements, and in accordance with Accounting Standards Codification (“ASC”)
855-10 “Subsequent Events”, the Company’s management has evaluated subsequent events through the date that the financial statements
were filed.

42

Table of Contents

In the opinion of management, all estimates and adjustments considered necessary for a fair presentation have been included and all such
adjustments were normal and recurring.

Consolidation

The  consolidated  financial  statements,  which  have  been  prepared  in  accordance  with  accounting  principles  generally  accepted  in  the
United States, represent all companies of which Hudson directly or indirectly has majority ownership or otherwise controls. Significant
intercompany accounts and transactions have been eliminated. The Company’s consolidated financial statements include the accounts of
wholly-owned subsidiaries Hudson Holdings, Inc. and Hudson Technologies Company. The Company does not present a statement of
comprehensive income (loss) as its comprehensive income (loss) is the same as its net income (loss).

Fair Value of Financial Instruments

The carrying values of financial instruments including cash, trade accounts receivable and accounts payable approximate fair value at
December 31, 2021 and December 31, 2020, because of the relatively short maturity of these instruments. The carrying value of debt
approximates fair value, due to the variable rate nature of the debt, as of December 31, 2021 and December 31, 2020. Please see Note 2
for further details.

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
and, at times, the balances exceed FDIC insurance coverage. The Company’s trade accounts receivable are primarily due from companies
throughout the United States. The Company reviews each customer’s credit history before extending credit.

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

For the year ended December 31, 2021, one customer accounted for 10% of the Company’s revenues and at December 31, 2021, there
were $3.1 million of outstanding receivables from this customer.For the year ended December 31, 2020, one customer accounted for 14%
of the Company's revenues and at December 31, 2020, there were $2.9 million of outstanding receivables from this customer.

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

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 refrigerant products available for sale, are stated at the lower of cost, on a first-in first-out basis, or
net realizable value. Where the market price of inventory is less than the related cost, the Company may be required to write down its
inventory  through  a  lower  of  cost  or  net  realizable  value  adjustment,  the  impact  of  which  would  be  reflected  in  cost  of  sales  on  the
Consolidated Statements of Operations. Any such adjustment would be based on management’s judgment regarding future demand and
market conditions and analysis of historical experience.

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

43

Table of Contents

amortized on a straight-line basis over the shorter of economic life or terms of the respective leases. Costs of maintenance and repairs are
charged to expense when incurred.

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

Goodwill

The Company has made acquisitions that included a significant amount of goodwill and other intangible assets. The Company applies the
purchase method of accounting for acquisitions, which among other things, requires the recognition of goodwill (which represents the
excess of the purchase price of the acquisition over the fair value of the net assets acquired and identified intangible assets). We test our
goodwill for impairment annually on a qualitative or quantitative basis (the first day of the fourth quarter) and between annual tests if an
event occurs or circumstances change that would more likely than not reduce the fair value of an asset below its carrying value. Goodwill
is tested for impairment at the reporting unit level. When performing the annual impairment test, we have the option of first performing a
qualitative assessment, which requires management to make assumptions affecting a reporting unit, to determine the existence of events
and circumstances that would lead to a determination that it is more likely than not that the fair value of a reporting unit is less than its
carrying amount. If such a conclusion is reached, we are then required to perform a quantitative impairment assessment of goodwill. The
Company  has  one  reporting  unit  at  December  31,  2021.  Other  intangible  assets  that  meet  certain  criteria  are  amortized  over  their
estimated useful lives.

An impairment charge is recorded based on the excess of a reporting unit’s carrying amount over its fair value. An impairment charge
would be recognized when the carrying amount exceeds the estimated fair value of a reporting unit. These impairment evaluations use
many  assumptions  and  estimates  in  determining  an  impairment  loss,  including  certain  assumptions  and  estimates  related  to  future
earnings.  If  the  Company  does  not  achieve  its  earnings  objectives,  the  assumptions  and  estimates  underlying  these  impairment
evaluations could be adversely affected, which could result in an asset impairment charge that would negatively impact operating results.
During  the  fourth  quarter  of  2021,  we  completed  our  annual  impairment  test  as  of  October  1  and  determined  in  our  qualitative
assessment  that  it  is  more  likely  than  not  that  the  fair  value  of  the  reporting  unit  is  greater  than  its  carrying  amount,  resulting  in  no
goodwill impairment. There can be no assurances that future sustained declines in macroeconomic or business conditions affecting our
industry will not occur, which could result in goodwill impairment charges in future periods.

There were no goodwill impairment losses recognized in 2020 or 2021.

Leases

In February 2016, the FASB issued Accounting Standards Update No. 2016-02, Leases (Topic 842) (ASU 2016-02), as amended, which
generally requires lessees to recognize operating and financing lease liabilities and corresponding right-of-use assets on the balance sheet
and to provide enhanced disclosures surrounding the amount, timing and uncertainty of cash flows arising from leasing arrangements. In
July 2018, the FASB issued ASU No. 2018-11, Leases - Targeted Improvements, as an update to the previously-issued guidance. This
update added a transition option which allows for the recognition of a cumulative effect adjustment to the opening balance of retained
earnings  in  the  period  of  adoption  without  recasting  the  financial  statements  in  periods  prior  to  adoption.  The  Company  has  used  the
modified  retrospective  transition  approach  in  ASU  No.  2018-11  and  applied  the  new  lease  requirements  through  a  cumulative-effect
adjustment in the period of adoption. The Company elected the package of practical expedients permitted under the transition guidance,
which allows it to carryforward its historical lease classification, its assessment on whether a contract is or contains a lease, and its initial
direct costs for any leases that existed prior to adoption of the new standard. The Company also elected to combine lease and non-lease
components and to keep leases with an initial term of 12 months or less off the balance sheet and recognize the associated lease payments
in  the  consolidated  statements  of  operations  on  a  straight-line  basis  over  the  lease  term.  The  Company  recorded  approximately  $8.1
million  as  total  right-of-use  assets  and  total  lease  liabilities  on  its  consolidated  balance  sheet  as  of  January  1,  2019.  The  Company's
accounting for finance leases remained substantially unchanged. Please see Note 6 for further details and current balances.

Cylinder Deposit Liability

The  cylinder  deposit  liability,  which  is  included  in  Accrued  expenses  and  other  current  liabilities  on  the  Company’s  Balance  Sheet,
represents  the  amount  due  to  customers  for  the  return  of  refillable  cylinders.    ARI  charges  its  customers  cylinder  deposits  upon  the
shipment of refrigerant gases that are contained in refillable cylinders.  The amount charged to the customer by ARI approximates the

44

Table of Contents

cost of a new cylinder of the same size.  Upon return of a cylinder, this liability is reduced.  The cylinder deposit liability balance was
$12.3 million and $11.3 million at December 31, 2021 and 2020, respectively. 

Revenues and Cost of Sales

The Company’s products and services are primarily used in commercial air conditioning, industrial processing and refrigeration systems.
Most of the Company’s revenues are realized from the sale of refrigerant and industrial gases and related products. The Company also
generates  revenue  from  refrigerant  management  services  performed  at  a  customer’s  site  and  in-house.  The  Company  conducts  its
business primarily within the US.

The Company applies the FASB’s guidance on revenue recognition, which requires the Company to recognize revenue in an amount that
reflects the consideration to which the Company expects to be entitled in exchange for goods or services transferred to its customers. In
most instances, the Company’s contract with a customer is the customer’s purchase order and the sales price to the customer is fixed. For
certain customers, the Company may also enter into a sales agreement outlining a framework of terms and conditions applicable to future
purchase  orders  received  from  that  customer.  Because  the  Company’s  contracts  with  customers  are  typically  for  a  single  customer
purchase order, the duration of the contract is usually less than one year. The Company’s performance obligations related to product sales
are satisfied at a point in time, which may occur upon shipment of the product or receipt by the customer, depending on the terms of the
arrangement. The Company’s performance obligations related to reclamation and RefrigerantSide® services are generally satisfied at a
point in time when the service is performed. Accordingly revenues are recorded upon the shipment of the product, or in certain instances
upon receipt by the customer, or the completion of the service.

In July 2016 the Company was awarded, as prime contractor, a five-year contract, including a five-year renewal option,which has been
exercised,  by  the  United  States  Defense  Logistics  Agency  (“DLA”)  for  the  management,  supply,  and  sale  of  refrigerants,  compressed
gases,  cylinders  and  related  services.  Due  to  the  contract  containing  multiple  performance  obligations,  the  Company  assessed  the
arrangement in accordance with ASC 606. The Company determined that the sale of refrigerants and the management services provided
under the contract each have stand-alone value. Accordingly, the performance obligations related to the sale of refrigerants is satisfied at
a  point  in  time,  mainly  when  the  customer  receives  and  obtains  control  of  the  product.  The  performance  obligation  related  to
management service revenue is satisfied over time and revenue is recognized on a straight-line basis over the term of the arrangement as
the management services are provided.

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.  In  general,  the  Company  performs  shipping  and  handling  services  for  its  customers  in  connection  with  the  delivery  of
refrigerant  and  other  products.  The  Company  elected  to  implement  ASC  606-10-25-18B,  whereby  the  Company  accounts  for  such
shipping  and  handling  as  activities  to  fulfill  the  promise  to  transfer  the  good.  To  the  extent  that  the  Company  charges  its  customers
shipping fees, such amounts are included as a component of revenue and the corresponding costs are included as a component of cost of
sales.

The Company’s revenues are derived from Product and related sales and RefrigerantSide® Services revenues. The revenues for each of
these lines are as follows:

The Company is taxed at statutory corporate income tax rates after adjusting income reported for financial statement purposes for certain
items.  Current  income  tax  expense  (benefit)  reflects  the  tax  results  of  revenues  and  expenses  currently  taxable  or  deductible.  The
Company utilizes the asset and liability method of accounting for deferred income taxes, which provides for the recognition of deferred
tax assets or liabilities, based on enacted tax rates and laws, for the differences between the financial and income tax reporting bases of
assets and liabilities.

45

    
    
 
 
Table of Contents

The tax benefit associated with the Company’s net operating loss carry forwards (“NOLs”) is recognized to the extent that the Company
expects  to  realize  future  taxable  income.  As  a  result  of  a  prior  “change  in  control”,  as  defined  by  the  Internal  Revenue  Service,  the
Company’s ability to utilize its existing NOLs is subject to certain annual limitations. To the extent that the Company utilizes its NOLs, it
will not pay tax on such income. However, to the extent that the Company’s net income, if any, exceeds the annual NOL limitation, it
will pay income taxes based on the then existing statutory rates. In addition, certain states either do not allow or limit NOLs and as such
the Company will be liable for certain state income taxes.

As of December 31, 2021, the Company had federal NOLs of approximately $29.3 million, none of which have an expiration date and
which  are  subject  to  annual  limitations  of  80%  of  taxable  earnings.  As  of  December  31,  2021,  the  Company  had  state  tax  NOLs  of
approximately $21.0 million expiring in various years. We review the likelihood that we will realize the benefit of our deferred tax assets,
and  therefore  the  need  for  valuation  allowances,  on  an  annual  basis  in  the  fourth  quarter  of  the  year,  and  more  frequently  if  events
indicate that a review is required. In determining the requirement for a valuation allowance, the historical and projected financial results
are considered, along with all other available positive and negative evidence.

Concluding  that  a  valuation  allowance  is  not  required  is  difficult  when  there  is  significant  negative  evidence  that  is  objective  and
verifiable, such as cumulative losses in recent years. We utilize a rolling twelve quarters of pre-tax income or loss adjusted for significant
permanent book to tax differences, as well as non-recurring items, as a measure of our cumulative results in recent years. Based on our
assessment as of December 31, 2018, 2019, 2020 and 2021, we concluded that due to the uncertainty that the deferred tax assets will not
be  fully  realized  in  the  future,  we  recorded  a  valuation  allowance  of  approximately  $11.3  million  during  2018,  and  due  to  additional
losses, increased the valuation allowance through 2019 and 2020 to $19.0 million. For the year ended December 31, 2021, and due to
additional income that resulted in the utilization of net operating losses of $16.8 million, we reduced the valuation allowance by $3.9
million resulting in an ending balance of $15.1 million as of December 31, 2021.

The Company evaluates uncertain tax positions, if any, by determining if it is more likely than not to be sustained upon examination by
the taxing authorities. As of December 31, 2021 and December 31, 2020, the Company believes it had no uncertain tax positions and
there are no open federal or state examinations.

Income (loss) per Common and Equivalent Shares

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

Net income (loss)

Weighted average number of shares – basic
Shares underlying options

During  the  years  ended  December  31,  2021  and  2020,  certain  options  aggregating  2,583,523  and  5,329,515  shares,  respectively,  have
been excluded from the calculation of diluted shares, due to the fact that their effect would be anti-dilutive.

Estimates and Risks

The preparation of financial statements in conformity with generally accepted accounting principles in the United States requires the use
of estimates and assumptions that affect the amounts reported in these financial statements and footnotes. The Company considers these
accounting  estimates  to  be  critical  in  the  preparation  of  the  accompanying  consolidated  financial  statements.  The  Company  uses
information available at the time the estimates are made. However, these estimates could change materially if different information or
assumptions were used including potential impact of COVID-19 uncertainties. Additionally, these estimates may not ultimately reflect
the  actual  amounts  of  the  final  transactions  that  occur.  The  Company  utilizes  both  internal  and  external  sources  to  evaluate  potential
current and future liabilities for various commitments and contingencies. In the event that the assumptions or conditions change in the
future, the estimates could differ from the original estimates.

46

    
    
 
 
Table of Contents

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

The Company participates in an industry that is highly regulated, and changes in the regulations affecting its business could affect its
operating  results.  Currently  the  Company  purchases  virgin  hydrochlorofluorocarbon  (“HCFC”)  and  hydrofluorocarbon  (“HFC”)
refrigerants and reclaimable, primarily HCFC, HFC and chlorofluorocarbon (“CFC”), refrigerants from suppliers and its customers. To
the extent that the Company is unable to source sufficient quantities of refrigerants or is unable to obtain refrigerants on commercially
reasonable  terms  or  experiences  a  decline  in  demand  and/or  price  for  refrigerants  sold  by  the  Company,  the  Company  could  realize
reductions in revenue from refrigerant sales, which could have a material adverse effect on its operating results and its financial position.
The process of sourcing refrigerants includes various procurement costs, such as freight, processing, insurance, and other costs, relating
to the delivery of refrigerants. As a result of the recently noted global supply chain issues, the Company determined it could be exposed
to incremental costs related to these refrigerant purchases. These costs represent the Company’s initial estimate that are possibly subject
to finalization in future periods and are recorded in accrued expenses and other current liabilities on the consolidated balance sheet as of
December 31, 2021.

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

Impairment of Long-lived Assets

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

Recent Accounting Pronouncements

In June 2016, the FASB issued ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments, which revises guidance for
the accounting for credit losses on financial instruments within its scope, and in November 2018, issued ASU No. 2018-19 and in April
2019, issued ASU No. 2019-04 and in May 2019, issued ASU No. 2019-05, and in November 2019, issued ASU No. 2019-11, which
each amended the standard. The new standard introduces an approach, based on expected losses, to estimate credit losses on certain types
of financial instruments and modifies the impairment model for available-for-sale debt securities. The new approach to estimating credit
losses (referred to as the current expected credit losses model) applies to most financial assets measured at amortized cost and certain
other  instruments,  including  trade  and  other  receivables,  loans,  held-to-maturity  debt  securities,  net  investments  in  leases  and  off-
balance-sheet  credit  exposures.  This  ASU  is  effective  for  fiscal  years  beginning  after  December  15,  2022,  including  interim  periods
within those fiscal years, with early adoption permitted. Entities are required to apply the standard's provisions as a cumulative-effect
adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is adopted. The Company is still
evaluating the impact of this ASU.

In  March  2020,  the  FASB  issued  ASU  2020-04,  which  provides  relief  from  accounting  analysis  and  impacts  that  may  otherwise  be
required  for  modifications  to  agreements  necessitated  by  reference  rate  reform.  It  also  provides  optional  expedients  to  enable  the
continuance of hedge accounting where certain hedging relationships are impacted by reference rate reform. This optional guidance is

effective immediately, and available to be used through December 31, 2022. We are assessing the impact that reference rate reform and
the related adoption of this guidance will have on our financial statements.

In August 2020, the FASB issued ASU 2020-06, "Debt-Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and
Hedging-Contracts in Entity's Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity's Own
Equity",  which  is  intended  to  simplify  the  accounting  for  convertible  instruments  by  removing  certain  separation  models  in  Subtopic
470-20, Debt-Debt with Conversion and Other Options, for convertible instruments. The pronouncement is effective for fiscal years, and
for  interim  periods  within  those  fiscal  years,  beginning  after  December  15,  2021,  with  early  adoption  permitted.  ASU  2020-06  is  not
expected to have a material impact on our financial statements.

Note 2- Fair Value

ASC Subtopic 820-10 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly
transaction  between  market  participants  at  the  measurement  date.  The  Company  often  utilizes  certain  assumptions  that  market
participants  would  use  in  pricing  the  asset  or  liability,  including  assumptions  about  risk  and/or  the  risks  inherent  in  the  inputs  to  the
valuation  technique.  These  inputs  can  be  readily  observable,  market-corroborated,  or  generally  unobservable  inputs.  The  Company
utilizes  valuation  techniques  that  maximize  the  use  of  observable  inputs  and  minimize  the  use  of  unobservable  inputs.  Based  upon
observable inputs used in the valuation techniques, the Company is required to provide information according to the fair value hierarchy.

The  fair  value  hierarchy  ranks  the  quality  and  reliability  of  the  information  used  to  determine  fair  values  into  three  broad  levels  as
follows:

Level  1:  Valuations  for  assets  and  liabilities  traded  in  active  markets  from  readily  available  pricing  sources  for  market  transactions
involving identical assets or liabilities.

Level  2:  Valuations  for  assets  and  liabilities  traded  in  less  active  dealer  or  broker  markets.  Valuations  are  obtained  from  third-party
pricing services for identical or similar assets or liabilities.

Level 3: Valuations for assets and liabilities include certain unobservable inputs in the assumptions and projections used in determining
the fair value assigned to such assets or liabilities.

In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the
level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant
to  the  fair  value  measurement  in  its  entirety.  The  Company’s  assessment  of  the  significance  of  a  particular  input  to  the  fair  value
measurement in its entirety requires judgment and considers factors specific to the asset or liability.

Depreciation expense for the years ended December 31, 2021 and 2020 was $3.4 million and $3.2 million, respectively, of which $1.9
million and $1.7 million, respectively, were included as cost of sales in the Company’s Consolidated Statements of Operations.

Note 6 - Leases

The Company has various lease agreements with terms up to 11 years, including leases of buildings and various equipment. Some leases
include options to purchase, terminate or extend for one or more years. These options are included in the lease term when it is reasonably
certain that the option will be exercised.

At  inception,  the  Company  determines  if  an  arrangement  contains  a  lease  and  whether  that  lease  meets  the  classification  criteria  of  a
finance or operating lease. Some of the Company’s lease arrangements contain lease components (e.g. minimum rent payments) and non-
lease components (e.g. common area maintenance, charges, utilities and property taxes). The Company elected the package of practical
expedients permitted under the transition guidance, which allows it to carry forward its historical lease classification, its assessment on
whether a contract contains a lease, and its initial direct costs for any leases that existed prior to the adoption of the new standard. The
Company also elected to combine lease and non-lease components and to keep leases with an initial term of 12 months or less off the
balance sheet and recognize the associated lease payments in the consolidated statements of operations on a straight line basis over the
lease term. The Company’s lease agreements do not contain any material residual value, guarantees or material restrictive covenants.

Operating leases are included in Right of use asset, Accrued expenses and other current liabilities, and Long-term lease liabilities on the
consolidated  balance  sheets.  These  assets  and  liabilities  are  recognized  at  the  commencement  date  based  on  the  present  value  of
remaining lease payments over the lease term using the Company’s secured incremental borrowing rates or implicit rates, when readily
determinable. Short-term operating leases, which have an initial term of 12 months or less, are not recorded on the balance sheet. Lease
expense for operating leases is recognized on a straight-line basis over the lease term. Variable lease expense is recognized in the period
in which the obligation for those payments is incurred.

Operating lease expense of $3.1 million and $3.0 million, for the years ended December 31, 2021 and 2020, respectively, is included in
Selling, general and administrative expenses on the consolidated statements of operations.

We review the likelihood that we will realize the benefit of our deferred tax assets, and therefore the need for valuation allowances, on an
annual basis in the fourth quarter of the year, and more frequently if events indicate that a review is required. In determining the

requirement for a valuation allowance, the historical and projected financial results are considered, along with all other available positive
and negative evidence.

Concluding  that  a  valuation  allowance  is  not  required  is  difficult  when  there  is  significant  negative  evidence  that  is  objective  and
verifiable, such as cumulative losses in recent years. We utilize a rolling twelve quarters of pre-tax income or loss adjusted for significant
permanent book to tax differences, as well as non-recurring items, as a measure of our cumulative results in recent years. Based on our
assessment as of December 31, 2018, 2019, 2020 and 2021, we concluded that due to the uncertainty that the deferred tax assets will not
be  fully  realized  in  the  future,  we  recorded  a  valuation  allowance  of  approximately  $11.3  million  during  2018,  and  due  to  additional
losses, increased the valuation allowance through 2019 and 2020 to $19.0 million. For the year ended December 31, 2021, and due to
additional income that resulted in the utilization of net operating losses of $16.8 million, we reduced the valuation allowance by $3.9
million resulting in an ending balance of $15.1 million as of December 31, 2021.

The Company’s 2015 and prior federal tax years have been closed. The Company operates in many states throughout the United States
and, as of December 31, 2021, the state statutes of limitations remain open for tax years subsequent to 2016. The Company recognizes
interest and penalties, if any, relating to income taxes as a component of the provision for income taxes

Note 8 – Goodwill and intangible assets

Goodwill represents the excess of the purchase price over the fair value of the net assets acquired in business combinations accounted for
under the purchase method of accounting.

There were no goodwill impairment losses recognized for the years ended December 31, 2021 and 2020.

Based  on  the  results  of  the  impairment  assessments  of  goodwill  and  intangible  assets  performed,  management  concluded  that  the  fair
value of the Company’s goodwill exceeds the carrying value and that there are no impairment indicators related to intangible assets.

At December 31, 2021 and December 31, 2020 the Company had $47.8 million of goodwill.

On  December  19,  2019,  Hudson  Technologies  Company  (“HTC”),  Hudson  Holdings,  Inc.  (“Holdings”)  and  Aspen  Refrigerants,  Inc.
(“ARI”), as borrowers (collectively, the “Borrowers”), and Hudson Technologies, Inc. (the “Company”) as a guarantor, became obligated
under a Credit Agreement (the “Wells Fargo Facility”) with Wells Fargo Bank, as administrative agent and lender (“Agent” or “Wells
Fargo”) and such other lenders as may thereafter become a party to the Wells Fargo Facility. The Wells Fargo Facility was amended and
restated on March 2, 2022 (see Note 14).

Under the terms of the Wells Fargo Facility, the Borrowers could borrow, from time to time, up to $60 million at any time consisting of
revolving loans in a maximum amount up to the lesser of $60 million and a borrowing base that was calculated based on the outstanding
amount of the Borrowers’ eligible receivables and eligible inventory, as described in the Wells Fargo Facility. The Wells Fargo Facility
also contained a sublimit of $5 million for swing line loans and $2 million for letters of credit.

Amounts borrowed under the Wells Fargo Facility were used by the Borrowers to repay existing revolving indebtedness under its prior
revolving credit facility, repay certain principal amounts under the Term Loan Facility (as defined below), and for working capital needs,
certain permitted acquisitions, and to reimburse drawings under letters of credit.

Interest on loans under the Wells Fargo Facility was payable in arrears on the first day of each month. Interest charges with respect to
loans were computed on the actual principal amount of loans outstanding during the month at a rate per annum equal to (A) with respect
to Base Rate loans, the sum of (i) a rate per annum equal to the higher of (1) the federal funds rate plus 0.5%, (2) one month LIBOR plus
1.0%,  and  (3)  the  prime  commercial  lending  rate  of  Wells  Fargo,  plus  (ii)  between  1.25%  and  1.75%  depending  on  average  monthly
undrawn availability and (B) with respect to LIBOR rate loans, the sum of the LIBOR rate plus between 2.25% and 2.75% depending on
average monthly undrawn availability.

In connection with the closing of the Wells Fargo Facility, the Company also entered into a Guaranty and Security Agreement, dated as
of  December  19,  2019  (the  “Revolver  Guaranty  and  Security  Agreement”),  pursuant  to  which  the  Company  and  certain  subsidiaries
unconditionally guaranteed the payment and performance of all obligations owing by Borrowers to Wells Fargo, as Agent for the benefit
of  the  revolving  lenders.  Pursuant  to  the  Revolver  Guaranty  and  Security  Agreement,  Borrowers,  the  Company  and  certain  other
subsidiaries  granted  to  the  Agent,  for  the  benefit  of  the  Wells  Fargo  Facility  lenders,  a  security  interest  in  substantially  all  of  their
respective assets, including receivables, equipment, general intangibles (including intellectual property), inventory, subsidiary stock, real
property, and certain other assets.

Table of Contents

The  Revolver  Guaranty  and  Security  Agreement  also  provided  that  the  Agent  shall  receive  the  right  to  dominion  over  certain  of  the
Borrowers’ bank accounts in the event of an Event of Default under the Wells Fargo Facility, or if undrawn availability under the Wells
Fargo Facility falls below $9 million at any time.

The Wells Fargo Facility contained a financial covenant requiring the Company to maintain at all times minimum liquidity (defined as
availability under the Wells Fargo Facility plus unrestricted cash) of at least $5 million, of which at least $3 million must be derived from
availability. The Wells Fargo Facility also contained a springing covenant, which took effect only upon a failure to maintain undrawn
availability of at least $7.5 million, requiring the Company to maintain a Fixed Charge Coverage Ratio (FCCR) of not less than 1.00 to
1.00, as of the end of each trailing period of twelve consecutive fiscal months commencing with the month prior to the triggering of the
covenant.  The  FCCR  (as  defined  in  the  Wells  Fargo  Facility)  is  the  ratio  of  (a)  EBITDA  for  such  period,  minus  unfinanced  capital
expenditures made during such period, to (b) the aggregate amount of (i) interest expense required to be paid (other than interest paid-in-
kind,  amortization  of  financing  fees,  and  other  non-cash  interest  expense)  during  such  period,  (ii)  scheduled  principal  payments  (but
excluding principal payments relating to outstanding revolving loans under the Wells Fargo Facility), (iii) all net federal, state, and local
income taxes required to be paid during such period (provided, that any tax refunds received shall be applied to the period in which the
cash outlay for such taxes was made), (iv) all restricted payments paid (as defined in the Wells Fargo Facility) during such period, and (v)
to the extent not otherwise deducted from EBITDA for such period, all payments required to be made during such period in respect of
any funding deficiency or funding shortfall with respect to any pension plan. The FCCR covenant ceases after the Borrowers have been
in compliance therewith for two consecutive months.

The  Wells  Fargo  Facility  also  contained  customary  non-financial  covenants  relating  to  the  Company  and  the  Borrowers,  including
limitations  on  Borrowers’  ability  to  pay  dividends  on  common  stock  or  preferred  stock,  and  also  includes  certain  events  of  default,
including payment defaults, breaches of representations and warranties, covenant defaults, cross-defaults to other obligations, events of
bankruptcy and insolvency, certain ERISA events, judgments in excess of specified amounts, impairments to guarantees and a change of
control. The Wells Fargo Facility also contained certain covenants contained in the Fourth Amendment to the Prior Term Loan Facility
described below.

On April 23, 2020, the Borrowers, the Company and its subsidiaries entered into a First Amendment to Credit Agreement with Wells
Fargo  (the  "First  Amendment").  The  First  Amendment  authorized  the  Company  and  its  subsidiaries  to  incur  up  to  $2.5  million  of
indebtedness under the Coronavirus Aid, Relief, and Economic Security Act (the "CARES Act") and contained other provisions relating
to the treatment of such proceeds and any potential debt forgiveness, under the Wells Fargo Facility.

The commitments under the Wells Fargo Facility were to expire and the full outstanding principal amount of the loans, together with
accrued and unpaid interest, would have been due and payable in full on December 19, 2022, unless the commitments are terminated and
the outstanding principal amount of the loans were accelerated sooner following an event of default.

Prior Term Loan Facility

On  October  10,  2017,  HTC,  Holdings,  and  ARI,  as  borrowers,  and  the  Company,  as  guarantor,  became  obligated  under  a  Term  Loan
Credit  and  Security  Agreement  (as  amended,  the  “Prior  Term  Loan  Facility”)  with  U.S.  Bank  National  Association,  as  administrative
agent  and  collateral  agent  (“Prior  Term  Loan  Agent”)  and  funds  advised  by  FS  Investments  and  such  other  lenders  as  may  thereafter
become  a  party  to  the  Term  Loan  Facility  (the  “Prior  Term  Loan  Lenders”).  The  Prior  Term  Loan  Facility  was  repaid  in  full  and
terminated on March 2, 2022 (see Note 14).

Under the terms of the Prior Term Loan Facility, the Borrowers immediately borrowed $105 million pursuant to a term loan (the “Prior
Term Loan").

The Prior Term Loan was to mature on October 10, 2023. Interest on the Prior Term Loan was generally payable on the earlier of the last
day of the interest period applicable to such Eurodollar rate loan and the last day of the Term Loan Facility, as applicable. Interest is
payable at the rate per annum of the Eurodollar Rate (as defined in the Term Loan Facility) plus 10.25%. The Borrowers had the option
of paying 3.00% interest per annum in kind by adding such amount to the principal of the Prior Term Loans during no more than five
fiscal quarters during the term of the Prior Term Loan Facility.

Borrowers and the Company granted to the Prior Term Loan Agent, for the benefit of the Prior Term Loan Lenders, a security interest in
substantially  all  of  their  respective  assets,  including  receivables,  equipment,  general  intangibles  (including  intellectual  property),
inventory, subsidiary stock, real property, and certain other assets.

The Term Loan Facility contained a financial covenant requiring the Company to maintain a specified total leverage ratio (“TLR”), tested
as of the last day of the fiscal quarter. The TLR (as defined in the Term Loan Facility) is the ratio of (a) funded debt as of such day to (b)
EBITDA for the four consecutive fiscal quarters ending on the last day of such fiscal quarter. Funded debt (as defined in the Prior Term
Loan Facility) includes amounts borrowed under the Wells Fargo Facility and the Prior Term Loan Facility as well as capitalized lease
obligations and other indebtedness for borrowed money maturing more than one year from the date of creation thereof. As of December
31, 2021 and 2020, the TLR was approximately 1.93 to 1 and 5.84 to 1, respectively.

The Prior Term Loan Facility also contained customary non-financial covenants relating to the Company and the Borrowers, including
limitations on their ability to pay dividends on common stock or preferred stock, and also included certain events of default, including
payment defaults, breaches of representations and warranties, covenant defaults, cross-defaults to other obligations, events of bankruptcy
and insolvency, certain ERISA events, judgments in excess of specified amounts, impairments to guarantees and a change of control.

In connection with the closing of the Prior Term Loan Facility, the Company also entered into a Guaranty and Suretyship Agreement,
dated as of October 10, 2017 (the “Prior Term Loan Guarantee”), pursuant to which the Company affirmed its unconditional guarantee of
the payment and performance of all obligations owing by Borrowers to Prior Term Loan Agent, as agent for the benefit of the Prior Term
Loan Lenders.

The Prior Term Loan Agent and the Agent have entered into an intercreditor agreement governing the relative priority of their security
interests  granted  by  the  Borrowers  and  the  Guarantor  in  the  collateral,  providing  that  the  Agent  would  have  a  first  priority  security
interest in the accounts receivable, inventory, deposit accounts and certain other assets (the “Revolving Credit Priority Collateral”) and
the Prior Term Loan Agent would have a first priority security interest in the equipment, real property, capital stock of subsidiaries and
certain other assets (the “Prior Term Loan Priority Collateral”).

On  December  19,  2019,  HTC,  Holdings  and  ARI  as  borrowers  and  the  Company  as  a  guarantor,  entered  into  a  Waiver  and  Fourth
Amendment to Term Loan Credit and Security Agreement (the “Fourth Amendment”) with U.S. Bank National Association, as collateral
agent and administrative agent, and the various lenders thereunder.

The Fourth Amendment waived financial covenant defaults at June 30, 2019 and September 30, 2019 and amended the Term Loan Credit
and  Security  Agreement  dated  October  10,  2017  (as  previously  amended,  the  “Term  Loan  Facility”)  to  reset  the  maximum  Total
Leverage Ratio covenant contained in the Prior Term Loan Facility at the indicated dates as follows: (i) September 30, 2019 - 15.67:1.00;
(ii)  December  31,  2019  –  14.54:1.00;  (iii)  March  31,  2020  –  16.57:1.00;  (iv)  June  30,  2020  –  10.87:1.00;  (v)  September  30,  2020  –
8.89:1.00; (vi) December 31, 2020 – 8.89:1.00; (vii) March 31, 2021 – 7.75:1.00; (viii) June 30, 2021 – 7.03:1.00; (ix) September 30,
2021  –  6.08:1.00;  and  (x)  December  31,  2021  –  5.36:1.00.  The  Fourth  Amendment  also  reset  the  minimum  liquidity  requirement
(consisting of cash plus undrawn availability on the Borrowers’ revolving loan facility) of $5 million, measured monthly. Furthermore,
the Fourth Amendment added a minimum LTM Adjusted EBITDA covenant as of the indicated dates as follows: (i) September 30, 2019
- $7.887 million; (ii) December 31, 2019 – $7.954 million; (iii) March 31, 2020 – $7.359 million; (iv) June 30, 2020 – $11.745 million;
(v) September 30, 2020 – $12.021 million; (vi) December 31, 2020 – $12.300 million; (vii) March 31, 2021 –$14.295 million; (viii) June
30, 2021 – $14.566 million; (ix) September 30, 2021 – $15.431 million; and (x) December 31, 2021 – $16.267 million.

The  Fourth  Amendment  also  (i)  continued  the  limitation  on  acquisitions  and  dividends,  (ii)  required  a  principal  repayment  of
$14,000,000  upon  execution  of  the  Fourth  Amendment  and  (iii)  increased  the  scheduled  quarterly  principal  repayments  to  $562,000
effective March 31, 2020 and $1,312,000 effective December 31, 2020.

The Fourth Amendment also terminated the exit fee payable to the term loan lenders, which would have been payable in full in cash
upon the earlier to occur of (x) repayment in full of the term loans, or (y) any acceleration of the term loans. In lieu of the exit fee, the
Fourth  Amendment  reinstated  a  prepayment  premium  equal  to  the  following  percentages  of  the  principal  amount  prepaid,  depending
upon the date of prepayment: (i) through March 31, 2020 – 0.50%; (ii) from April 1, 2020 through March 31, 2021 – 2.50%; and (iii)
from April 1, 2021 and thereafter – 5.00%.

The Fourth Amendment also added a new covenant providing that in the event of a breach of a financial covenant contained in the Term
Loan Facility or any failure to make a required principal repayment (a “Trigger Event”), then on or prior to six months after a Trigger
Event, the Company shall commence a process to (x) sell its businesses and/or assets, and/or (y) consummate a refinancing transaction
with respect to the Term Loan Facility (a “Transaction”), in each case, subject to enumerated time milestones contained in the Fourth
Amendment, and which requires that Transaction shall, in any event, be consummated on or prior to the eighteen (18) month anniversary
of the Trigger Event.

As closing conditions to the execution and delivery of the Fourth Amendment, the Company was required to: (i) amend its Bylaws in a
manner acceptable to the Term Loan Facility lenders; (ii) appoint two new independent directors to the board of directors (the “Special
Directors”); and (iii) pay an amendment fee of 0.50% of the amount of the outstanding loans under the Term Loan Facility.

On April 23, 2020, HTC, Holdings and ARI as borrowers and the Company as a guarantor, entered into a Fifth Amendment to Term
Loan  Credit  and  Security  Agreement  (the  "Fifth  Amendment")  with  U.S.  Bank  National  Association,  as  collateral  agent  and
administrative agent, and the various lenders thereunder. The Fifth Amendment authorized the Company and its subsidiaries to incur up
to $2.5 million of indebtedness under the CARES Act and contained other provisions relating to the treatment of such proceeds and any
potential debt forgiveness, under the Prior Term Loan Facility.

The  Company  evaluated  the  Fourth  and  Fifth  Amendments  in  accordance  with  the  provisions  of  Accounting  Standards  Codification
(“ASC”)  470,  Debt,  to  determine  if  the  Amendments  were  (1)  a  troubled  debt  restructuring,  and  if  not,  (2)  a  modification  or  an
extinguishment of debt. The Company concluded that the Fourth Amendment was a troubled debt restructuring for accounting purposes
due to the removal of the exit fee; as such, the Company capitalized an additional $0.5 million of deferred financing costs, which are
being amortized over the remaining term. The future undiscounted cash flows of the term loan, as amended, exceeded the carrying value,
and accordingly, no gain was recognized and no adjustment was made to the carrying value of the debt.

The Company was in compliance with all covenants, under the Prior Wells Fargo Facility and the Term Loan Facility, as amended, as of
December 31, 2021.

The  Company's  ability  to  comply  with  these  covenants  in  future  quarters  may  be  affected  by  events  beyond  the  Company's  control,
including general economic conditions, weather conditions, regulations and refrigerant pricing. Therefore, we cannot make any assurance
that we will continue to be in compliance during future periods.

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

CARES Act Loan

On April 23, 2020 the Company received a loan in the amount of $2.475 million from Meridian Bank under the Paycheck Protection
Program ("PPP") pursuant to the CARES Act. The loan had a term of two years, was unsecured, and bore interest at a fixed rate of one
percent per annum, with the first nine months of principal and interest deferred. As a result of the COVID-19 pandemic, in applying for
the  loan  the  Company  made  a  good  faith  assertion  based  upon  the  degree  of  uncertainty  introduced  to  the  capital  markets  and  the
industries affecting the Company's customers and the Company's dependency to curtail expenses to fund ongoing operations. The PPP
loan proceeds have been used in part to help offset payroll costs as stipulated in the legislation. All or a portion of the PPP loan may be
forgiven by the U.S. Small Business Administration ("SBA") upon application by the Company and upon documentation of expenditures
in accordance with the SBA requirements. Under the CARES Act, loan forgiveness is available for the sum of documented payroll costs
and  other  covered  areas,  such  as  rent  payments,  mortgage  interest  and  utilities,  as  applicable.  During  the  third  quarter  of  2021,  the
Company  received  forgiveness  of  the  loan  from  the  SBA,  resulting  in  $2.475  million  of  Other  Income  recorded  in  the  Company’s
Consolidated Statements of Operations.

Vehicle and Equipment Loans

The  Company  has  from  time  to  time  entered  into  various  vehicle  and  equipment  loans.  These  loans  were  payable  in  60  monthly
payments through July 2021 and bore interest ranging from 0.0% to 8.3%. All such loans have been repaid in full at December 31, 2021.

Capital Lease Obligations

The Company rents certain equipment with a de minimis net book value at December 31, 2021 under leases which have been classified
as capital leases.

The Company rents properties and various equipment under operating leases. Operating lease expense for the years ended December 31,
2021  and  2020  totaled  approximately  $3.1  million  and  $3.0  million.  In  addition  to  the  properties  above,  the  Company  does  at  times
utilize  public  warehouse  space  on  a  month  to  month  basis.  The  Company  typically  enters  into  short-term  leases  for  the  facilities  and
wherever possible extends the expiration date of such leases.

Note 12 - Share-Based Compensation

Share-based  compensation  represents  the  cost  related  to  share-based  awards,  typically  stock  options  or  stock  grants,  granted  to
employees, non-employees, officers and directors. Share-based compensation is measured at grant date, based on the estimated aggregate
fair value of the award on the grant date, and such amount is charged to compensation expense on a straight-line basis over the requisite
service  period.  For  the  years  ended  December  31,  2021  and  2020,  the  share-based  compensation  expense  of  $0.5  million  and  $0.7
million, respectively, is reflected in General and administrative expenses in the consolidated Statements of Operations.

Share-based awards have historically been made as stock options, and recently also as stock grants, issued pursuant to the terms of the
Company’s stock option and stock incentive plans, (collectively, the “Plans”), described below. The Plans may be administered by the
Board  of  Directors  or  the  Compensation  Committee  of  the  Board  or  by  another  committee  appointed  by  the  Board  from  among  its
members as provided in the Plans. Presently, the Plans are administered by the Company’s Compensation Committee of the Board of

57

    
 
 
 
 
    
    
Table of Contents

Directors. As of December 31, 2021 there were 5,069,255 shares of the Company’s common stock available under the Plans for issuance
for future stock option grants or other stock based awards.

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

ISOs granted under the Plans may not be granted at a price less than the fair market value of the common stock on the date of grant (or
110% of fair market value in the case of persons holding 10% or more of the voting stock of the Company). Nonqualified options granted
under the Plans may not be granted at a price less than the fair market value of the common stock. Options granted under the Plans 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 September 17, 2014, the Company adopted its 2014 Stock Incentive Plan (“2014 Plan”) pursuant to which 3,000,000 shares of
common  stock  were  reserved  for  issuance  (i)  upon  the  exercise  of  options,  designated  as  either  ISOs  under  the  Code  or  nonqualified
options, or (ii) as stock, deferred stock or other stock-based awards. ISOs may be granted under the 2014 Plan to employees and officers
of  the  Company.  Non-qualified  options,  stock,  deferred  stock  or  other  stock-based  awards  may  be  granted  to  consultants,  directors
(whether or not they are employees), employees or officers of the Company. Stock appreciation rights may also be issued in tandem with
stock options. Unless the 2014 Plan is sooner terminated, the ability to grant options or other awards under the 2014 Plan will expire on
September 17, 2024.

Effective  June  7,  2018,  the  Company  adopted  its  2018  Stock  Incentive  Plan  (“2018  Plan”)  pursuant  to  which  4,000,000  shares  of
common  stock  were  reserved  for  issuance  (i)  upon  the  exercise  of  options,  designated  as  either  ISOs  under  the  Code  or  nonqualified
options, or (ii) as stock, deferred stock or other stock-based awards. ISOs may be granted under the 2018 Plan to employees and officers
of  the  Company.  Non-qualified  options,  stock,  deferred  stock  or  other  stock-based  awards  may  be  granted  to  consultants,  directors
(whether or not they are employees), employees or officers of the Company. Stock appreciation rights may also be issued in tandem with
stock options. Unless the 2018 Plan is sooner terminated, the ability to grant options or other awards under the 2018 Plan will expire on
June 7, 2028.

Effective  June  11,  2020,  the  Company  adopted  its  2020  Stock  Incentive  Plan  ("2020  Plan")  pursuant  to  which  3,000,000  shares  of
common  stock  were  reserved  for  issuance  (i)  upon  the  exercise  of  options,  designated  as  either  ISOs  under  the  Code  or  nonqualified
options, or (ii) as stock, deferred stock or other stock-based awards. ISOs may be granted under the 2020 Plan to employees and officers
of  the  Company.  Non-qualified  options,  stock,  deferred  stock  or  other  stock-based  awards  may  be  granted  to  consultants,  directors
(whether or not they are employees), employees or officers of the Company. Stock appreciation rights may also be issued in tandem with
stock options. Unless the 2020 Plan is sooner terminated, the ability to grant options or other awards under the 2020 Plan will expire on
June 11, 2030.

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

The Company determines the fair value of share based awards at the grant date by using the Black-Scholes option-pricing model, and has
utilized  the  “simplified”  method,  as  prescribed  by  the  SEC’s  Staff  Accounting  Bulletin  (“SAB”)  No.110,  Share-Based  Payment,  to
compute expected lives of share based awards with the following weighted-average assumptions:

Executive Officer. Effective September 1, 2020, Mr. Mandracchia became a member of the Company's Board of Directors.

Note 15 – Subsequent Events

2022 Term Loan Facility

On March 2, 2022, Hudson Technologies Company (“HTC”), an indirect subsidiary of Hudson Technologies, Inc. (the “Company”), and
the Company’s subsidiary Hudson Holdings, Inc., as borrowers (collectively, the “Borrowers”), and the Company, as guarantor, became
obligated under a Credit Agreement (the “Term Loan Facility”) with TCW Asset Management Company LLC, as administrative agent
(“Term Loan Agent”) and the lender parties thereto (the “Term Loan Lenders”).

Under the terms of the Term Loan Facility, the Borrowers have immediately borrowed $85 million pursuant to a term loan (the “Term
Loan”).  Amounts borrowed under the Term Loan Facility were used by the Borrowers to repay the outstanding principal amount and
related fees and expenses under the Prior Term Loan Facility (as defined below) and for other corporate purposes.

The Term Loan matures on March 2, 2027, or earlier upon certain acceleration or cross default events. Principal payments on the Term
Loan  are  required  on  a  quarterly  basis,  commencing  with  the  quarter  ending  March  31,  2022,  in  the  amount  of  5%  of  the  original
principal  amount  of  the  outstanding  Term  Loan  per  annum.  The  Term  Loan  Facility  also  requires  annual  payments  of  50%  of  Excess
Cash Flow (as defined in the Term Loan Facility); provided that commencing with the year ending December 31, 2023 such payments
may be reduced depending upon the Company’s leverage ratio (as defined in the Term Loan Facility) for the applicable year. The Term
Loan Facility also requires mandatory prepayments of the Term Loans in the event of certain asset dispositions, debt issuances, and other
events. The Term Loan may be prepaid at the option of the Borrowers subject to a prepayment premium of 3% in year one, 2% in year
two, 1% in year three, and zero in year four and thereafter.

Interest on the Term Loan is generally payable monthly, in arrears.  Interest charges with respect to the Term Loan are computed on the
actual principal amount of the Term Loan outstanding at a rate per annum equal to (A) with respect to Base Rate loans, the sum of (i) a
rate per annum equal to the higher of (1) 2.0%, (2) the federal funds rate plus 0.5%, (3) one month term SOFR plus 1.0%, and (4) the
prime commercial lending rate quoted by The Wall Street Journal, plus (ii) between 6.0% and 7.0% depending on the applicable leverage
ratio and (B) with respect to SOFR loans, the sum of the applicable SOFR rate plus between 7.0% and 8.0% depending on the applicable
leverage ratio.

Borrowers  and  the  Company  granted  to  the  Term  Loan  Agent,  for  the  benefit  of  the  Term  Loan  Lenders,  a  security  interest  in
substantially  all  of  their  respective  assets,  including  receivables,  equipment,  general  intangibles  (including  intellectual  property),
inventory, subsidiary stock, real property, and certain other assets.

The Term Loan Facility contains a fixed charge coverage ratio covenant and a leverage ratio covenant, each tested quarterly. The Term
Loan  Facility  also  contains  customary  non-financial  covenants  relating  to  the  Company  and  the  Borrowers,  including  limitations  on
Borrowers’ ability to pay dividends on common stock or preferred stock, and also includes certain events of default, including payment
defaults,  breaches  of  representations  and  warranties,  covenant  defaults,  cross-defaults  to  other  obligations,  events  of  bankruptcy  and
insolvency, certain ERISA events, judgments in excess of specified amounts, impairments to guarantees and a change of control.

In connection with the closing of the Term Loan Facility, the Company also entered into a Guaranty and Security Agreement, dated as of
March 2, 2022 (the “Term Loan Guarantee”), pursuant to which the Company affirmed its unconditional guarantee of the payment and
performance of all obligations owing by Borrowers to Term Loan Agent, as agent for the benefit of the Term Loan Lenders.

The Term Loan Agent and the Agent (as defined below) have entered into an intercreditor agreement governing the relative priority of
their security interests granted by the Borrowers and the Guarantor in the collateral, providing that the Agent shall have a first priority
security  interest  in  the  accounts  receivable,  inventory,  deposit  accounts  and  certain  other  assets  (the  “Revolving  Credit  Priority
Collateral”)  and  the  Term  Loan  Agent  shall  have  a  first  priority  security  interest  in  the  equipment,  real  property,  capital  stock  of
subsidiaries and certain other assets (the “Term Loan Priority Collateral”).

Termination of Prior Term Loan Facility

In conjunction with entry into the new Term Loan Facility as described above, on March 2, 2022 the Company's existing term loans set
forth in the Term Loan Credit and Security Agreement with U.S. Bank National Association, as collateral agent and administrative agent,
and the various lenders thereunder, as amended (the “Prior Term Loan Facility”), which had a principal balance of approximately $63.9
million after payment of a $16.0 million excess cash flow amount thereunder, was repaid in full, together with associated required lender
fees and expenses of $3.3 million, and the Prior Term Loan Facility was terminated.

Revolving Credit Facility Amendment

On March 2, 2022, Hudson Technologies Company (“HTC”) and Hudson Holdings, Inc. (“Holdings”), as borrowers (collectively, the
“Borrowers”), and Hudson Technologies, Inc (the “Company”) as a guarantor, entered into an Amended and Restated Credit Agreement
(the  “Amended  Wells  Fargo  Facility”)  with  Wells  Fargo  Bank,  National  Association,  as  administrative  agent  and  lender  (“Agent”  or
“Wells Fargo”) and such other lenders as have or may thereafter become a party to the Wells Fargo Facility. The Amended Wells Fargo
facility amended and restated the prior Wells Fargo Facility.

Under  the  terms  of  the  Amended  Wells  Fargo  Facility,  the  Borrowers  may  borrow  up  to  $90  million  consisting  of:  (i)  $15  million
immediately borrowed in the form of a “first in last out” term loan (the “FILO Tranche”) and (ii) from time to time, up to $75 million at
any time consisting of revolving loans (the “Revolving Loans”) in a maximum amount up to the lesser of $75 million and a borrowing
base that is calculated based on the outstanding amount of the Borrowers’ eligible receivables and eligible inventory, as described in the
Amended Wells Fargo Facility. The Amended Wells Fargo Facility also contains a sublimit of $9 million for swing line loans and $2
million for letters of credit.

Amounts borrowed under the Amended Wells Fargo Facility may be used for working capital needs, certain permitted acquisitions, and
to reimburse drawings under letters of credit.

Interest under the Amended Wells Fargo Facility is payable in arrears on the first day of each month. Interest charges with respect to
Revolving Loans are computed on the actual principal amount of Revolving Loans outstanding at a rate per annum equal to (A) with
respect to Base Rate loans, the sum of (i) a rate per annum equal to the higher of (1) 1.0%, (2) the federal funds rate plus 0.5%, (3) one
month term SOFR plus 1.0%, and (4) the prime commercial lending rate of Wells Fargo, plus (ii) between 1.25% and 1.75% depending
on average monthly undrawn availability and (B) with respect to SOFR loans, the sum of the applicable SOFR rate plus between 2.36%
and 2.86% depending on average quarterly undrawn availability.  Interest charges with respect to the FILO Tranche are computed on the
actual principal amount of FILO Tranche loans outstanding at a rate per annum equal to (A) with respect to Base Rate FILO Tranche
loans, the sum of (i) a rate per annum equal to the higher of (1) 1.0%, (2) the federal funds rate plus 0.5%, (3) one month term SOFR plus
1.0%, and (4) the prime commercial lending rate of Wells Fargo, plus (ii) 6.5% and (B) with respect to SOFR FILO Tranche loans, the
sum of the applicable SOFR rate plus 7.50%.

In connection with the closing of the Amended Wells Fargo Facility, the Company also entered into a First Amendment to Guaranty and
Security  Agreement,  dated  as  of  March  2,  2022  (the  “Amended  Revolver  Guaranty  and  Security  Agreement”),  pursuant  to  which  the
Company and certain subsidiaries are continuing to unconditionally guarantee the payment and performance of all obligations owing by
Borrowers to Wells Fargo, as Agent for the benefit of the revolving lenders. Pursuant to the Revolver Guaranty and Security Agreement,
as amended, Borrowers, the Company and certain other subsidiaries are continuing to grant to the Agent, for the benefit of the Wells
Fargo  Facility  lenders,  a  security  interest  in  substantially  all  of  their  respective  assets,  including  receivables,  equipment,  general
intangibles (including intellectual property), inventory, subsidiary stock, real property, and certain other assets.

The  Amended  Wells  Fargo  Facility  contains  a  financial  covenant  requiring  the  Company  to  maintain  at  all  times  minimum  liquidity
(defined as availability under the Amended Wells Fargo Facility plus unrestricted cash) of at least $5 million, of which at least $3 million
must be derived from availability. The Amended Wells Fargo Facility also contains a springing covenant, which takes effect only upon a
failure  to  maintain  undrawn  availability  of  at  least  $11.25  million  or  upon  an  election  by  the  Borrowers  to  increase  the  inventory
component of the borrowing base, requiring the Company to maintain a Fixed Charge Coverage Ratio (FCCR) of not less than 1.00 to
1.00,  as  of  the  end  of  each  trailing  period  of  twelve  consecutive  months  commencing  with  the  month  prior  to  the  triggering  of  the
covenant.  The  FCCR  (as  defined  in  the  Wells  Fargo  Facility)  is  the  ratio  of  (a)  EBITDA  for  such  period,  minus  unfinanced  capital
expenditures made during such period, to (b) the aggregate amount of (i) interest expense required to be paid (other than interest paid-in-
kind,  amortization  of  financing  fees,  and  other  non-cash  interest  expense)  during  such  period,  (ii)  scheduled  principal  payments  (but
excluding principal payments relating to outstanding Revolving Loans under the Amended Wells Fargo Facility), (iii) all net federal,

61

Table of Contents

state, and local income taxes required to be paid during such period (provided, that any tax refunds received shall be applied to the period
in which the cash outlay for such taxes was made), (iv) all restricted payments paid (as defined in the Amended Wells Fargo Facility)
during such period, and (v) to the extent not otherwise deducted from EBITDA for such period, all payments required to be made during
such period in respect of any funding deficiency or funding shortfall with respect to any pension plan. The FCCR covenant ceases after
the Borrowers have been in compliance therewith for two consecutive months.

The  Amended  Wells  Fargo  Facility  also  contains  customary  non-financial  covenants  relating  to  the  Company  and  the  Borrowers,
including  limitations  on  Borrowers’  ability  to  pay  dividends  on  common  stock  or  preferred  stock,  and  also  includes  certain  events  of
default,  including  payment  defaults,  breaches  of  representations  and  warranties,  covenant  defaults,  cross-defaults  to  other  obligations,
events of bankruptcy and insolvency, certain ERISA events, judgments in excess of specified amounts, impairments to guarantees and a
change of control.

The commitments under the Wells Fargo Facility will expire and the full outstanding principal amount of the loans, together with accrued
and unpaid interest, are due and payable in full on March 2, 2027, unless the commitments are terminated and the outstanding principal
amount of the loans are accelerated sooner following an event of default or in the event of certain other cross-defaults.

STOCK APPRECIATION RIGHTS AWARD
HUDSON TECHNOLOGIES, INC.

Exhibit 10.56

AGREEMENT made as of [DATE] (the "Grant Date") between Hudson Technologies, Inc. (the

"Company"), a New York corporation, having a principal place of business at PO Box 1541, One Blue Hill Plaza,
14th Floor, Pearl River, New York 10965, and [[FIRSTNAME]] [[LASTNAME]] (the "Grantee").

WHEREAS, the Company desires to grant to the Grantee Stock Appreciation Rights (the "SARs") with

respect to shares of its common stock, par value $.01 per share (the "Shares"), under and pursuant to Section 8 of
the Company’s 2014 Stock Incentive Plan (the "Plan");

WHEREAS, the Company and the Grantee understand and agree that unless otherwise defined herein any

terms used herein have the same meanings as in the Plan.

NOW, THEREFORE, in consideration of the mutual covenants hereinafter set forth and for other good and

valuable consideration, the parties hereto agree as follows:

1.

Grant of SARs.  The Company hereby grants to the Grantee SARs with respect to 250 Shares, on 
the terms and conditions, and subject to all the limitations set forth herein and in the Plan, which is incorporated 
herein by reference.  The SARs give the Grantee, upon vesting and exercise, the right to receive an amount equal 
to the difference between the Fair Market Value of a share of the Company’s Common Stock on the date of 
exercise over the Grant Price multiplied by the number of SARs being exercised (the "Spread"). The Grantee 
acknowledges receipt of a copy of the Plan.

2.

Purchase Price.  The purchase price of the Shares covered by the SARs shall be [$____] per share

(which amount shall not be less than Fair Market Value on the Grant Date).

3.

4.

Vesting of SARs.   The SARs granted hereby shall vest and be exercisable on or after [________].

Term of SARs.  The SARs shall terminate three years from the date of this Agreement (the 

"Expiration Date").  The SARs may be exercised during their term only to the extent they are vested. All SARs 
(whether or not vested) shall be forfeited and terminate on the earlier of (i) the date of the Grantee’s termination of 
employment for any reason and (ii) the Expiration Date.

5.

Non-Assignability.  The SARs shall not be transferable by the Grantee otherwise than by will or by 

the laws of descent and distribution and shall be exercisable, during the Grantee's lifetime, only by the Grantee.  
The SARs shall not be assigned, pledged or hypothecated in any way (whether by operation of law or otherwise) 
and shall not be subject to execution, attachment or similar process.  Any attempted transfer, assignment, pledge, 
hypothecation or other disposition of the SARs or of any rights granted hereunder contrary to the provisions of 
this Section 5, or the levy of any attachment or similar process upon the SARs or

1

such right, shall be null and void.

6.

Payment.  The SARs may be exercised in whole or in part (to the extent that it is exercisable in 
accordance with its terms) by giving written notice to the Company.  Such written notice shall be signed by the 
person exercising the SARs, shall state the number of Shares with respect to which the SAR is being exercised 
and shall otherwise comply with the terms and conditions of this Agreement and the Plan.  Upon valid exercise of 
the vested SARs, the Company shall pay the Grantee the Spread, less applicable withholdings, in either (i) a cash 
lump sum or (ii) in Shares with such payment being made within thirty (30) days of such exercise, without interest 
thereon. For the avoidance of doubt, the election to pay the Spread in cash or Shares shall be made by the 
Company in its sole discretion and the Grantee shall not have the ability to elect the form of payment of the SAR.

7.

Stockholder Rights.  Grantee acknowledges that he/she does not have any rights as a stockholder of 

the Company by reason of a grant of the SARs or settlement of the SARs pursuant to this Agreement unless and 
until Shares are actually distributed by the Company at its election in settlement of the SAR. Grantee further 
acknowledges that the SARs only entitle the Grantee, if at all, to an amount determined and payable pursuant to 
the terms of this Agreement.

8.

Notices.  Any notices required or permitted by the terms of this Agreement or the Plan shall be 

given by hand delivery, overnight courier service, or registered or certified mail, return receipt requested, and sent, 
if to the Company, at its principal executive offices, and if to the Grantee, at the Grantee’s most current residence 
address as reflected in the records of the Company or to such other address or addresses of which notice in the 
same manner has previously been given.  Any such notice shall be deemed to have been given when received in 
accordance with the foregoing provisions.  Either party hereto may change the address of which notices shall be 
given by providing the other party hereto with written notice of such change.

9.

Governing Law.  This Agreement shall be construed and enforced in accordance with the law of 

the State of New York.

10.

Benefit of Agreement.  This Agreement shall be for the benefit of and shall be binding upon the 

heirs, executors, administrators and successors of the parties hereto.

11.

Section 409A.  The SARs are intended to be exempt from the provisions of Section 409A of the 

Code and Department of Treasury regulations and other interpretive guidance issued thereunder, as providing for a 
right to compensation based on the appreciation in value of a specified number of shares of service recipient stock 
as described in Section 1.409A-1(b)(5)(i)(B) of the Department of Treasury regulations. Notwithstanding any 
provision of this Agreement to the contrary, in the event that the Company determines that the SARs may be 
subject to Section 409A of the Code and related Department of Treasury guidance (including such Department of 
Treasury guidance as may be issued after the date hereof), the Company may adopt such amendments to this 
Agreement or adopt other policies and procedures (including amendments, policies, and procedures with 
retroactive effect), or take any other actions, that the Company determines are necessary or appropriate to (a) 
exempt the SARs from Section 409A of

2

the Code and/or preserve the intended tax treatment of the benefits provided with respect to the SARs, or (b) 
comply with the requirements of Section 409A of the Code and related Department of Treasury guidance.  The 
Company makes no representation or warranty and shall have no liability to the Grantee or any other person if any 
SAR granted herein is determined to constitute deferred compensation under Section 409A of the Internal 
Revenue Code.

IN WITNESS WHEREOF, the Company has caused this Agreement to be executed by its duly authorized

officer, and the Grantee has hereunto set his or her hand, all as of the day and year first above written.
