Business

Background

PART I

We were formed as a Delaware corporation on June 20, 2014 for the purpose of engaging in the business of recycling lead through a
novel, proprietary and patent-pending process that we developed and named “AquaRefining”. Since our formation, we have focused our
efforts on the development and testing of our AquaRefining process, the development of our business plan, the raise of our present working
capital and the development of our initial lead acid battery, or LAB, recycling facility in the Tahoe Regional Industrial Center, McCarran,
Nevada (“TRIC”).

We  completed  the  development  of  our  first  LAB  recycling  facility  at  TRIC  and  commenced  production  of  battery  breaking  and
limited  operations  during  the  first  quarter  of  2017. The  TRIC  facility  now  produces  varying  products  for  commercial  sales  primarily
consisting  of  ingoted AquaRefined  lead,  lead  compounds,  ingoted  hard  lead  and  as  well  as  plastic. In April  2017,  we  commenced  the
shipment of products for sale, consisting of lead compounds as well as plastics. In April 2018, we commenced the limited production of
lead bullion, including AquaRefined lead. In July 2018, we commenced the sale of pure AquaRefined lead in the form of two tonne blocks,
and in October 2018, we commenced the sale of AquaRefined lead in the form of battery manufacturing ready ingots.  In November 2018,
we  received  official  vendor  certification  from  Johnson  Controls  for  our  AquaRefined  lead  and  in  December  2018,  we  commenced
shipments directly to Johnson Controls owned and partner battery manufacturing facilities.

After several months of engaging in extensive diligence and engineering evaluations, on February 28, 2019, we has entered into an
Operations,  Management  and  Maintenance  Agreement  with  Veolia  North  America  Regeneration  Services  LLC  (Veolia)  to  provide
operations, maintenance and management services at our Aqua Metals' AquaRefining facility in McCarran, Nevada.

Veolia is expected to contribute operational and technological expertise and organizational capabilities in aqueous based process
chemistries and electrolysis along with taking on responsibility for operations, supply chain, offtake and management of the plant. Veolia
employees will begin working onsite starting March 4, 2019 at the McCarran facility. In addition to receiving expertise and support from
Veolia North America resources overall, this Agreement provides for Veolia to relocate up to six (6) full time employees with strong
operations, process engineering, management expertise to join the Aqua Metals team at our AquaRefinery in McCarran, Nevada. Veolia
North America will take over the primary responsibility for scaling the facility through the remainder of 2019 to CP1-16 (Commercial
Plant 1, 16 AquaRefining modules) of capacity. The Agreement also provides for Veolia and Aqua Metals to work together to plan in 2019
and complete the expansion of the TRIC facility to 32 AquaRefining modules.

We believe the Agreement will allow us to leverage off Veolia’s supply chain and offtake and waste stream buying power and

expertise. The intention of the parties is to grow the relationship where Veolia will serve as Aqua Metals’ go to market execution partner to
staff and manage AquaRefining facilities with mutually agreed performance metrics for Aqua Metals and our partners. We expect this will
begin with the first facility we deploy with Johnson Controls Power Systems Division (being transitioned to Brookfield Asset Management,
which has over $350B of assets under management) as a part of our efforts to complete the Joint Development Agreement with them by
June 2019, with the blueprint for deploying AquaRefining upgrades to existing battery recycling facilities. A more complete summary of
the terms of the Agreement is set forth in Part II, Item 9.B. "Other Information."

Veolia North America Regeneration Services, LLC is the wholly-owned subsidiary of Veolia Environnement S. A. (Paris
Euronext: VIE). Veolia​ Environnement is the global leader in optimized resource management. With nearly 169,000 employees worldwide,
Veolia Environnement designs and provides water, waste and energy management solutions that contribute to the sustainable development
of communities and industries. Through its three complementary business activities, Veolia Environnement helps to develop access to
resources, preserve available resources, and to replenish them. In 2017, Veolia Environnement supplied 96 million people with drinking
water and 62 million people with wastewater service, produced nearly 55 million megawatt hours of energy and converted 47 million
metric tons of waste into new materials and energy. Veolia Environnement recorded consolidated revenue of USD 30.1 billion in 2017.

Overview

Aqua Metals is seeking to reinvent lead recycling with its patented and patent-pending AquaRefining ™ technology. Unlike smelting,
AquaRefining  is  a  room  temperature,  water-based  process.  It  is  deployed  as  a  factory  built  modular  system  which  allows  the  lead-acid
battery  industry  to  simultaneously  improve  environmental  impact  and  scale  production  to  meet  demand. Aqua  Metals  has  built  its  first
recycling  facility  in  Nevada’s  Tahoe  Reno  Industrial  Complex.  Lead  is  a  globally  traded  commodity  with  a  worldwide  market  value  in
excess of $20 billion. Lead acid batteries (LABs) are the primary consumer use of all lead produced in the world. Because the chemical and
metallurgical properties of lead allow it to be recycled and reused indefinitely, LABs are also the dominant feed source for lead production
across the world. As such, LABs are almost 100% recycled for purposes of capturing the lead contained therein for re-use. We believe that
our  proprietary  and  patented AquaRefining  process  will  provide  for  the  existing  LAB  recycling  facility  to  leverage  our  capabilities  for
expanded  production  of  a  much  higher  purity  lead  with  fewer  environmental  and  regulatory  issues  than  is  possible  with  the  current
conventional methods of lead production.

In  recent  years,  recycled  lead  has  become  increasingly  important  to  LAB  production.  Recycled  lead  surpassed  mined  lead  in  the
1990s and now represents more than 60% of the lead content in new LABs. Whether it is produced from lead ore or recycled LABs, lead
has historically been produced by smelting. Smelting is a high-temperature, metallurgical/chemical reduction, energy intensive and often a
highly  polluting  process. As  a  consequence  of  the  environmental  and  health  issues,  lead  smelting  has  become  increasingly  regulated  in
many countries. In the U.S., regulatory non-compliance has forced the closure of large lead smelters in Vernon, California, Frisco, Texas
and Herculaneum, Missouri over the last several years. In response to increasing environmental regulation over the past three decades, there
has been an expansion of LAB smelting capacity in Mexico and other less regulated countries. The resulting transportation of used LABs
from  where  they  originate  in  the  U.S.  to  smelters  in  Mexico,  South  Korea,  the  Philippines  and  elsewhere  is  an  increasingly  significant
logistical and global environmental cost.

AquaRefining  uses  a  bio-degradable  aqueous  solvent  and  a  novel  ambient  temperature  electro-chemical  process  to  produce  lead
suitable for use in LAB production. Our AquaRefining process produces lead with a purity that is equivalent to primary lead (i.e., higher
than 99.99% purity). We believe that AquaRefining can provide a more efficient production process as compared with alternative methods
of  producing  equivalent  grades  of  lead.  We  also  have  the  potential  to  locate AquaRefining  facilities  closer  to  the  source  of  used  LABs,
thereby  reducing  transport  costs  and  supply  chain  bottlenecks.  On  this  basis,  we  believe  that AquaRefining  reduces  environmental  plant
emissions,  health  concerns  and  permitting  needs  compared  with  lead  smelting.  We  believe  that  the  combined  advantages  offered  by
AquaRefining represent a potential step change in lead recycling technology that includes improved product quality, advantages in footprint
and logistics as well as reduced environmental impact.

The modular nature of AquaRefining makes it possible both to start LAB recycling at a smaller scale than is possible with a typical
smelter  setup,  and  to  add AquaRefining  to  existing  battery  recycling  operations  to  expand  production  capacity  or  to  reduce  smelting
processes. Our plan is to pursue two complementary business streams. The first is to supply AquaRefining and supporting equipment to
third parties to supplement or replace smelting in their battery recycling operations. We intend to pursue this at least initially through our
relationship with Johnson Controls Inc., with which we have entered exploratory discussions centered on the addition of AquaRefining to
one of its existing battery recycling operations. We also intend to pursue similar arrangements with other companies operating recycling
operations.  The  second  is  to  expand  our  own  lead  recycling  operations  at  our  plant  in  McCarran,  Nevada,  subject  to  our  receipt  of
additional capital.

Our Markets

The Lead Market

Lead is a globally traded metal commodity and is the essential component of over 80% of the world’s rechargeable batteries. Lead is
globally traded primarily on the London Metals Exchange, or LME, although the smaller Shanghai Metals Exchange (SHME) in China also
trades the element. Conventionally in the industry, there are two separate groupings of lead: i) primary lead which refers to lead produced at
primary smelters that use mined lead concentrates (generally lead sulfide) as their major feedstock, and ii) secondary lead which refers to
lead smelters utilizing LABs as their main feed source.

Originally, the majority of the lead used in batteries was sourced from primary smelters but in recent decades, secondary lead has
grown  to  become  the  dominate  product  used.  Industry  data  shows  that  six  million  metric  tons  of  lead  was  produced  in  1995  of  which
approximately 45% was primary and 55% was from secondary sources. Twenty years later, by 2015, global lead production had increased
to approximately 11 million metric tons, of which more than 65% was secondary. Importantly, primary lead production had increased only
marginally  during  this  period.  This  marginal  increase  is  partially  due  to  lead-zinc  mine  deposits  are  being  depleted  across  the  globe  in
existing mines. As such, an increasing quantity of primary lead is now the predominate byproduct of zinc mining.

In 2005, secondary lead traded on the LME in a range of $1,000 to $1,200 per metric ton. During 2018, secondary lead traded in a

range of approximately $1,900 to $2,700 per metric ton.

4

 
 
 
 
 
 
 
 
As  noted  above,  although  lead  is  traded  as  a  commodity  on  the  LME/SHME,  the  major  sales  are  the  sales  directly  between
producers/  traders  and  users  (whom  are  typically  battery  manufacturers).  The  LME  daily  price  is  used  as  the  benchmark  in  forming  the
basis  of  physical  trades,  forward  contracts  and  hedge  strategies  for  both  primary  and  secondary  lead.  Based  on  market  and  product
knowledge with buyers of lead in the U.S. and Global lead markets, different grades (termed alloys) of lead are traded at a premium to the
base LME price. Lead alloys, which are generally specifically designed for the customer, are also sold at a premium above the base LME,
whereas by-products (generally lead compounds or scrap) are traded at a discount to the LME as they are based on the lead content and its
form. 

Lead Smelting

Currently, smelters produce virtually all the world’s mined and recycled lead. Smelting is an energy intensive and, in some poorly
managed plants, a highly polluting process. At its core, smelting is a relatively high temperature (excess of 900°C) metallurgical reduction
process in which lead compounds are heated and reacted with various reducing agents to remove the oxygen, sulfur, and other impurities.
The process leaves behind bullion lead and waste slag. In smelting, depending upon the operation, 0.5% to 5% of the lead can be lost to the
“slag”, with the resultant lead bullion containing both wanted and unwanted impurities.

In  developed  countries,  there  is  both  increased  environmental  regulation  and  enforcement  of  such,  including  monitoring  of
permissible  blood  lead  levels  in  employees  and  local  populations.  These  regulations  and  the  increasing  enforcement  have  made  it  more
expensive  to  operate  smelters.  According  to  a  report  titled  “Hazardous  Trade?”  produced  by  the  Secretariat  of  the  Commission  for
Environmental Cooperation in 2013, this has led to a decline of lead smelters in the U.S., an expansion of smelting operations in Mexico
and a resultant increase in the export of used LABs from the U.S. followed by the re-import of recycled lead. This trade is believed to be
largely  driven  by  the  lower  costs  related  to  the  less  stringent  environmental  standards  and  enforcement  in  Mexico.  For  the  foregoing
reasons, we believe that lead smelting facilities are increasingly located in less regulated areas remote from both the source of used LABs
and the demand for lead. We believe that the remote location of smelting increases the transport costs to the production of recycled lead.

Lead Acid Batteries

Although  the  LAB  is  one  of  the  earliest  battery  technologies,  in  terms  of  energy  capacity  deployed  and  installed  manufacturing
capacity, it still dominates the battery industry today. Historically, the largest market for LABs has been as starter batteries for vehicles.
However,  with  the  increasing  electrical  load  on  modern  vehicles  and  the  adoption  of  “Stop-Start”  conventional  12V  “starter  batteries”,
LABs are evolving into more capable and higher value products. At the same time, large new markets such as Cell Tower, Data Center and
Industrial back-up are adding to demand. Consequently, existing LAB production facilities are being expanded and new facilities are being
built.

According  to  CHR  Metals,  total  lead  output  in  2017  was  expected  to  be  20%  higher  than  it  was  in  2012.  Similar  prospects  for
healthy growth in the lead industry continue to be published and support continued growth in demand for lead for at least the next 20 years.
We believe that grid storage and other energy storage applications linked to renewable energy (solar and wind) will also generate increased
demand for LABs, where low cost, safety and reliability will make them attractive options.

The increase in LAB manufacturing in general and particularly in China, India and Southeast Asia, has increased demand for lead,
putting  pressure  on  global  recycling  networks  to  meet  this  demand. At  present,  we  believe  that  much  of  the  LAB  recycling  performed
outside  of  the  U.S.,  Canada,  the  EU,  Japan,  and Australia  is  carried  out  in  outdated  facilities  with  poor  environmental  standards  and
insufficient enforcement. China, India, Pakistan and South America appear to be moving toward tougher regulation and enforcement. We
believe that this will drive a demand in foreign markets for more less polluting LAB recycling processes.

AquaRefining Process

We developed AquaRefining to be a less expensive, cleaner and modular alternative to smelting. Our process has two key elements,
both of which are integral to our issued patents and pending-patent applications. The first is our use of a proprietary, non-toxic solvent that
dissolves  lead  compounds.  The  second  is  a  proprietary  electro-chemical  process  and  electrolyzer  that  converts  the  dissolved  lead
compounds into high purity lead suitable for use in LAB production.

Similar to conventional LAB smelter recycling, our AquaRefining process begins with the crushing of used LABs and the separation
of the metallic lead, active material (lead compounds), sulfuric acid and plastic for recycling. The active material (lead compounds) are first
processed to remove sulfur and then dissolved in our solvent. Lead is then plated from the solvent using our patented and patent-pending
process allowing the solvent to be reused.

Our AquaRefining process can generate the following outputs:

5

 
 
 
 
 
 
 
 
 
 
 
 
•

•

Lead and lead-based products, including high purity lead, lead alloys and lead compounds which are primarily intended
for  the  LAB  industry.  We  are  also  exploring  higher  value  lead-based  products  which  may  offer  performance  and  life-
cycle benefits to the LAB industry; and

Recovered  plastic  chips,  intended  for  re-use  in  the  manufacture  of  battery  casings  and  other  recycled  plastic
products.

We expect to derive revenue primarily from the sale of lead-based products, with additional revenue derived from the sale of plastic

chips.

A  significant  benefit  of  our AquaRefining  process  is  that  it  is  capable  of  producing  higher  purity  product  than  that  derived  from
primary  smelters  with  product  from  secondary  sources.  As  indicated  above,  primary  grade  lead  is  generally  sold  directly  to  battery
companies.

Another significant benefit of our process is that we designed our AquaRefining equipment to be manufactured on a purpose-built
production line in standard sized modules. This is not possible with the smelting process, as smelters need to be constructed on site. This
gives us the ability to provide AquaRefining systems with capacities ranging from four metric tons per day to more than 400 metric tons
per day all based on our standard module.

Lead recycling is subject to a variety of domestic and international regulations related to hazardous materials, emissions, employee
safety and other matters. While our operations will be subject to these regulations, we believe that one of our potential advantages will be
our  ability  to  conduct  lead  recycling  operations  with  less  regulatory  cost  and  burden  than  smelting  operators  due  to  the  nature  of  our
process.  One  of  our  key  objectives  will  be  to  educate  regulators  and  the  public  as  to  the  environmental  benefits  of AquaRefining.  We
believe  that  we  have  the  potential  to  develop  a  business  model  that  offers  the  opportunity  to  conduct,  in  an  environmentally  friendly
manner, an important recycling activity that historically has been conducted in an often highly polluting manner.

Our Business Model

Overall, our objective is to progress the lead recycling industry from one which is based primarily on smelting to one which is based
on AquaRefining. Our expectation is that this will be a moderately paced process of evolution in which multiple business models will be
evaluated. The two business models that we are currently most focused on are:

1)

2)

the supply of AquaRefining and supporting equipment and services to third parties to use in their recycling operations on
a  licensing  model.  We  are  currently  focused  on  exploring  this  business  stream  through  our  relationship  with  Johnson
Controls;

the  expansion  of  our  own  AquaRefining  capacity  and  facilities,  subject  to  our  receipt  of  additional
capital.

The  market  for  lead  is  global  in  scale  but  local  in  nature  and  execution,  with  large  differences  in  local  regulation,  custom  and
practice. In some regions, it is highly regulated, and in others it is not. Consequently, we are evolving our business model to commercialize
our technology optimally across multiple locations.

Lead recycling is subject to a variety of domestic and international regulations related to hazardous materials, emissions, employee
safety and other matters. While our operations will be subject to these regulations, we believe that one of our potential advantages will be
our ability to conduct lead recycling operations with less regulatory cost and burden than smelting operators. One of our key objectives will
be to educate regulators and the public as to the environmental benefits of AquaRefining. We believe we have the potential to develop a
business model that offers less regulatory cost and burden and the opportunity to conduct business in a socially responsible manner.

In  the  U.S.  and  similarly  regulated  countries,  our  plan  is  to  build  and  operate  LAB  recycling  facilities,  both  directly  and  in
association with third parties through joint ventures, licensing and direct sales. As an example, on February 7, 2017, we entered into a series
of  agreements  with  Johnson  Controls  Inc.,  (Johnson  Controls),  pursuant  to  which,  among  other  things,  we  agreed  to  work  with  Johnson
Controls on the development of a program for upgrades of Johnson Controls’ and certain strategic partners’ of Johnson Controls existing
lead smelters throughout North and South America, China and Europe to a lead recycling process utilizing our proprietary and patented
AquaRefining technology and equipment, know-how and services.

Competition

At the present time, our primary competition in the production of lead comes from operators of existing smelters and other parties
heavily  invested  in  the  existing  supply  chain  for  smelting.  Our  approach  to  this  competition  is  to  make AquaRefining  available  for  the
conversion of existing smelter-based facilities. However, it is prudent to assume that outside of our strategic relationships, a conversion to
AquaRefining  may  be  resisted  by  some  of  the  incumbent  lead  producers.  Competition  in  the  supply  of  lead  from  such  incumbents  may
come in the form of price competition for lead produced. However, to the extent we are successful in being a producer of high quality

6

 
 
 
 
 
 
 
 
lead  without  the  regulatory  costs  or  burden  associated  with  smelting,  we  should  be  able  to  compete  effectively  with  smelting  as  the
preferred method of recycling lead, at least in the more regulated jurisdictions.

Another area where incumbents may seek to compete is in controlling access to used LABs. The market for used LABs is made up
of the members of the LAB reverse supply chains, including auto repair shops, auto parts stores and auto dealers, LAB manufacturers who
operate their own smelting operations and third parties who  engage  in  the  purchase  and  sale  of  used  LABs.  We  believe  that  some  LAB
manufacturers who maintain their own smelting operations may feel threatened by our AquaRefining process. Such parties may attempt to
restrict our access to used LABs. We have assumed at least some level of interference by incumbents, however, based on our operations to
date, including our discussions and arrangements with certain suppliers of used LABs, we do not view access to used LABs be a significant
risk to our LAB recycling operations.

Our business plan is not dependent on the acceptance of our process by lead smelters. We still intend to initially focus on operating
our own AquaRefining facilities directly and working with Johnson Controls to implement Aqua Refining in a nominated lead smelting
facility followed by deployments with additional 3rd parties to propagate AquaRefining as the technology of choice for recycling LABs.

We do not expect to experience significant competition in connection with our sale of lead. We believe that the market for lead is
established,  fluid  and  effective;  and  like  the  markets  for  other  natural  resources,  such  as  oil,  gas,  gold,  silver,  etc.,  we  do  not  expect  to
encounter  any  issues,  conditions  or  qualifications  for  the  sale  of  our  lead  production  at  prevailing  market  prices  set  by  the  LME.  The
vertically integrated LAB manufacturers who conduct smelting operations also are buyers of lead from third parties. We believe that they
will still purchase lead from us if we are able to offer it at the market price.

Our First Recycling Facility: McCarran, Nevada

In  May  2015,  we  purchased  11.73  acres  of  undeveloped  land  in  the  Tahoe  Reno  Industrial  Center  (TRIC),  at  McCarran,  Nevada

where we subsequently built a 136,750 square foot LAB recycling facility.

The building phase was completed by August 2016, at which time we started installing and commissioning equipment. We installed
and  commissioned  the  first  production AquaRefining  module  in  October  2016  and  produced  our  first  lead  ingot  using  electrolyte  we
produced  on-site  using  materials  supplied  by  a  third  party,  which  were  recovered  from  recycled  batteries.  We  verified  that  the  lead  we
produced by this method was over 99.99 percent pure.

We commenced initial battery breaking during December 2016 and progressed to regular single shift operation of the battery breaker
in January 2017. From late 2016 through the date of this report, we implemented a number of upgrades to the facility, the battery breaking
and separation processes and other more conventional aspects of our process.

As of December 2017, we had installed 16 AquaRefining modules at TRIC.  To date, we have operated the first four of the 16
modules and have made continuous improvements which have led to individual modules running in a steady state producing 100Kg/hour
for  several  days  at  a  time. As  we  bring  the  modules  into  commercial  operation,  we  expect  to  continue  to  adjust  the  modules  to  further
enhance operation. Although we staffed the facility and ran one or two AquaRefining Modules on a 24x7 basis from October to December
2018, we are currently running one or two modules 24-hours a day, four days a week to allow safe times for some of the key work to be
completed for our contribution margin improvement projects. Subject to key work being completed in the first quarter of 2019, we intend to
re-instate  24‑hour,  seven  days  a  week,  continuous  operations  shortly  thereafter  and  scale  to  running  all  four  of  the  initial  four  modules
before  bringing  the  next  four  modules  on  line. We  believe  this  operational  strategy  will  allow  us  to  maximize  lead  production,  while
enabling the remaining components of the plant to be synchronized in support of increased AquaRefining. Once we are satisfied with the
operation of the first four modules, additional modules will be brought into production. This process will be repeated until full production
is reached with all 16 modules. Our goal is to operate all 16 modules on a 24/7 continuous basis by the end of 2019. However, due to the
delays and unforeseen issues in the completion of the AquaRefining production line we have experienced to date, there can be no assurance
that we will not encounter additional delays and issues. 

Supply, Off-Take and Other Strategic Agreements

In support of our first facility, we have entered into a series of agreements and relationships providing for our supply of LABs and
the  off-take  of  the  recycled  lead  we  produce. As  described  in  more  detail  below,  Interstate  Battery  has  agreed  to  supply  us  with  LABs
pursuant to a written agreement entered into in May 2016. In addition, we have established an important relationship with Battery Systems.
Inc.,  an  independent  LAB  distributor  with  a  distribution  facility  located  next  to  our  TRIC  facility,  for  Battery  Systems’  supply  of  used
LABS to us. We have also entered into an agreement with Johnson Controls pursuant to which Johnson Controls has agreed to purchase
from us, recycled lead on both a tolling (fee to convert used LABs to recycled materials) and merchanting (sale of recycled materials) basis.
We have made progress in diversifying our feedstock supply through various sources at more favorable pricing. Consequently, we believe
that we have secured an ample supply of used LABs and demand for our lead-based products for the foreseeable future.

Johnson Controls Agreements

Equipment Supply Agreement.  We  entered  into  an  equipment  supply  agreement  dated  February  7,  2017  with  Johnson  Controls
pursuant to which we agreed to collaborate on the development of a program for the installation of new greenfield builds and conversion of
existing Johnson Controls and certain strategic partners of Johnson Controls’ existing lead smelters to a lead recycling process utilizing our
proprietary and patent-pending AquaRefining technology and equipment, know-how and services. We have agreed with Johnson Controls
to develop an appropriate program blueprint, and enter into a definitive development program agreement reflecting that blueprint, pursuant
to which we will provide to Johnson Controls and certain strategic partners of Johnson Controls, by way of licensing or sale, the following
products and services in the regions of North and South America, Europe and China:

•

•

•

AquaRefining technology and the related equipment, engineering and systems integration support sufficient to convert or retrofit
existing  smelter-based  operations  and/or  the  construction  of  new  Johnson  Controls  and  Johnson  Controls’  strategic  partners’
battery recycling facilities based on our AquaRefining technology;

Training,  evaluation  and  certification  of  Johnson  Controls’  operations  personnel  sufficient  for  such  personnel  to  competently
operate our AquaRefining technology and equipment; and

Ongoing 
warranties.

technical 

support,  maintenance 

services  and

We plan to provide the above services and equipment to Johnson Controls in conjunction with our partner, Veolia North America
Regeneration Services, LLC, on a serviced license basis, including Johnson Controls’ ongoing licensing fees payable to us based on the
operational  capacity  of  the AquaRefining  equipment  supplied  by  us.  We  have  agreed  not  to  license  our AquaRefining  technology  and
equipment to third parties in the aforementioned regions until such time as we and Johnson Controls have agreed on certain matters relating
to the initial conversion of a Johnson Controls facility. Johnson Controls and we have agreed to use good faith, commercial best-efforts to
conclude the discussion and negotiation of the development program agreement no later than April 30, 2019, and to enter into a definitive
development program agreement no later than June 30, 2019. The equipment supply agreement may be terminated by either party upon 60
days’ prior written notice if the parties have not entered into the development program agreement by June 30, 2019, of which there can be
no assurance. The equipment supply agreement allows each party the right to seek early termination based on a material breach by the other
party that goes uncorrected for 30 days following notice of breach. The equipment supply agreement contains representations, warranties
and indemnities that are customary to commercial agreements of this nature.

Tolling/Lead Purchase Agreement. We have entered into a tolling/lead purchase agreement dated February 7, 2017 with Johnson
Controls pursuant to which we have agreed to sell to Johnson Controls, and Johnson Controls has agreed to purchase from us, recycled lead
on both a tolling (fee to convert used LABs to recycled materials) and merchanting (sale of recycled materials) basis.

Pursuant to the agreement, Johnson Controls has agreed to purchase from us, and we have agreed to sell to Johnson Controls, up to
100% of the recycled lead we produce for automotive applications, other than by way of tolling arrangements, on a monthly basis, unless
we receive notice from Johnson Controls six months advance of its intention to purchase less than 100% of our output in any given month.
Our agreement with Johnson Controls excludes, and we are free to manufacture and sell to third parties, recycled lead for non-automotive
uses, such as stationery batteries for back-up power systems for Internet/Cloud applications or grid scale storage applications. During fiscal
year 2018 and 2017, approximately 88% and 96% of our revenues, respectively, were derived from sales to Johnson Controls.

We have also agreed to provide tolling services to Johnson Controls whereby Johnson Controls will deliver to us used lead acid
batteries, or LABs, and we will recycle the used LABs and return the recycled lead to Johnson Controls for a fee. Johnson Controls has
agreed to send to us for tolling, and we have agreed to toll for Johnson Controls, used LABs representing a significant allocation of the
production capacity of our initial recycling facility in McCarran, Nevada. To date, none of our sales to Johnson Controls have been from
tolling.

The tolling/lead purchase agreement has a minimum term of five years and upon the expiration of the initial term the agreement,
either party can terminate the agreement upon three years prior written notice. Either party may elect to terminate the agreement for any
reason  after  the  second  anniversary  of  the  agreement,  which  termination  shall  be  effective  on  the  third  anniversary  of  the  notice  of
termination. Either party may terminate the agreement on ten days’ prior written notice of breach that goes uncorrected during the notice
period.  The  tolling/lead  purchase  agreement  contains  representations,  warranties  and  indemnities  that  are  customary  to  commercial
agreements of this nature.

In the fourth quarter of 2018, Johnson Controls International announced that it would sell its power solutions business, which
makes, distributes and recycles automotive batteries, to the investment firm Brookfield Business Partners L.P., in a cash deal valued at
$13.2 billion. The deal is expected to close in mid-2019. We have received no indication from Johnson Controls or Brookfield that their
current strategies relating to Aqua Metals may change.

Interstate Battery Partnership

On May 18, 2016, we entered into a supply agreement with Interstate Battery pursuant to which Interstate Battery agreed to sell to
us,  and  we  agreed  to  buy  from  Interstate  Battery,  used  LABs.  Interstate  Battery  will  sell  us  used  LABs  on  a  cost-plus  basis  and  the
agreement  subjects  us  and  Interstate  Battery  to  certain  minimum  purchase  and  sale  requirements.  We  have  granted  Interstate  Battery
limited rights of first refusal to supply our future AquaRefineries. Our agreement with Interstate Battery is for an initial term of 18 months
from the date of first delivery of used LABs to us and will be subject to automatic renewals thereafter unless either party elects to terminate
the agreement. The agreement allows each party the right to seek early termination based on certain commercial contingencies. The supply
agreement contains representations, warranties and indemnities that are customary to commercial agreements of this nature. In June 2018,
we reinvigorated our partnership and established an Omnibus Agreement with Interstate Battery in consideration of adjusting the terms of a
warrant to purchase 702,247 shares of our common stock from $7.12 per share to $3.33 per share and extending the expiration date of the
warrant  from  May  2018  to  June  2020. Interstate  Battery  materially  improved  our  feedstock  supply  pricing  and  agreed  to  waive  alleged
violations of a negative covenant related to our purchase of Ebonex as well as the Clark Key Man event. Interstate Battery also reworked
the Mould Key Man event to allow us to pay $500,000 for the transfer of the Key Man event to a Cotton Key Man event rather than paying
$2,000,000  for  a  Mould  Key  Man  event  as  previously  specified  in  the  Investor  Rights  Agreement.  We  opted  for  this  transfer  and
subsequently  paid  Interstate  Battery  the  $500,000  transfer  fee  in  February  2019. In  January  2019,  we  also  repaid  Interstate  Battery  the
outstanding principal and interest on the convertible debt in the amount of $6.7 million.

Intellectual Property Rights

We regard the protection of our technologies and intellectual property rights as an important element of our business operations and
crucial to our success. We endeavor to generate and protect our intellectual property assets through a series of patents, trademarks, internal
and external policy and procedures and contractual provisions.

Patent Portfolio

Currently, we have secured one US patent, 13 international patents, and two allowances (one US and one international). In addition
to  the  US  patent,  we  have  international  patents/allowances  in  the  European  Union,  Korea,  Japan,  China,  Australia,  Canada,  African
Intellectual  Property  Organization,  Mexico,  South Africa  and  the  Ukraine. We  also  have  90  patent  applications  pending  in  the  United
States  and  numerous  corresponding  patent  applications  pending  in  20  additional  jurisdictions  across  seven  distinct  patent  applications
relating to certain elements of the technology underlying our AquaRefining process and related apparatus and chemical formulations. The
claims of the granted patents substantially address the same subject matter and are drawn to various aspects of processing lead materials
using an aqua refining process. Differences in the claim number and scope are due to local rules and practice.

We intend to continue to prepare and file domestic and foreign patent applications covering expanding aspects and applications of

our technology, as circumstances warrant.

There can be no assurance that any patents will issue from any of our current or any future applications. Also, any patents that may
issue may not survive a legal challenge to their scope, validity or enforceability, or provide significant protection for us. Competitors may
work  around  our  patents  so  they  are  not  infringing.  Our  patent  portfolio  and  our  existing  policy  and  procedures  safeguarding  our  trade
secrets nonetheless may face challenges so that our competitors can copy our AquaRefining process.

Trademark Portfolio

We have filed for trademark registration in the US and foreign countries for the following trademarks:

Trade Secrets and Contract Protection

We have developed our internal policy and procedures in safeguarding our trade secrets and proprietary information. Our procedures
generally  require  our  employees,  consultants  and  advisors  to  enter  into  confidentiality  agreements.  These  agreements  provide  that  all
confidential information developed or made known to the individual during the course of the individual’s relationship with us is to be kept
confidential and not disclosed to third parties except under specific circumstances. In the case of our employees, the agreements provide
that all of the technology that is conceived by the individual during the course of employment is our exclusive property. The

9

 
 
 
 
 
 
 
 
 
development of our technology and many of our processes are dependent upon the knowledge, experience and skills of key scientific and
technical personnel.

Government Regulation

Our operations in the United States will be subject to the Federal, state and local environmental, health and safety laws applicable to
the reclamation of LABs. While the lead reclamation process itself is generally not subject to Federal permitting requirements, depending
on how any particular operation is structured, our facilities may have to obtain environmental permits or approvals from Federal, state or
local regulators to operate, including permits or regulatory approvals related to air emissions, water discharges, waste management, and the
storage  of  LABs  on-site  should  that  become  necessary.  We  may  face  opposition  from  local  residents  or  public  interest  groups  to  the
installation  and  operation  of  our  facilities.  Failure  to  secure  (or  significant  delays  in  securing)  the  necessary  approvals  could  prevent  us
from pursuing some of our planned operations and adversely affect our business, financial results and growth prospects.

In  addition  to  permitting  requirements,  our  operations  are  subject  to  environmental  health,  safety  and  transportation  laws  and
regulations that govern the management of and exposure to hazardous materials such as the lead and acids involved in LAB reclamation.
These  include  hazard  communication  and  other  occupational  safety  requirements  for  employees,  which  may  mandate  industrial  hygiene
monitoring of employees for potential exposure to lead. Failure to comply with these requirements could subject our business to significant
penalties (civil or criminal) and other sanctions that could adversely affect our business. Changes to these regulatory requirements in the
future could also increase our costs, require changes in or cessation of certain activities, and adversely affect the business.

The  nature  of  our  operations  involves  risks,  including  the  potential  for  exposure  to  hazardous  materials  such  as  lead,  that  could
result in personal injury and property damage claims from third parties, including employees and neighbors, which claims could result in
significant costs or other environmental liability. Our operations also pose a risk of releases of hazardous substances, such as lead or acids,
into  the  environment,  which  can  result  in  liabilities  for  the  removal  or  remediation  of  such  hazardous  substances  from  the  properties  at
which they have been released, liabilities which can be imposed regardless of fault, and our business could be held liable for the entire cost
of cleanup even if we were only partially responsible. Like any manufacturer, we are also subject to the possibility that we may receive
notices of potential liability in connection with materials that were sent to third-party recycling, treatment, and/or disposal facilities under
the Federal Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended (“CERCLA”), and comparable
state  statutes,  which  impose  liability  for  investigation  and  remediation  of  contamination  without  regard  to  fault  or  the  legality  of  the
conduct  that  contributed  to  the  contamination,  and  for  damages  to  natural  resources.  Liability  under  CERCLA  is  retroactive,  and,  under
certain circumstances, liability for the entire cost of a cleanup can be imposed on any responsible party.

As our business expands outside of the United States, our operations will be subject to the environmental, health and safety laws of
the countries where we do business, including permitting and compliance requirements that address the similar risks as do the laws in the
United States, as well as international legal requirements such as those applicable to the transportation of hazardous materials. Depending
on the country or region, these laws could be as stringent as those in the US, or they could be less stringent or not as strictly enforced. In
some countries in which we are interested in expanding our business, such as Mexico and China, the relevant environmental regulatory and
enforcement frameworks are in flux and subject to change. Therefore, while compliance with these requirements will cause our business to
incur costs, and failure to comply with these requirements could adversely affect our business, it is difficult to evaluate such potential costs
or adverse impacts until such time as we decide to initiate operations in particular countries outside the United States.

Employees

As of the date of this report, we employ 76 people on a full-time basis. None of our employees are represented by a labor union.

Financial and Segment Information

We operate our business as a single segment, as defined by generally accepted accounting principles. Our financial information is

Item 1A. Risk Factors

There  are  numerous  and  varied  risks,  known  and  unknown,  that  may  prevent  us  from  achieving  our  goals.  If  any  of  these  risks
actually occur, our business, financial condition or results of operation may be materially adversely affected.  In such case, the trading
price of our common stock could decline and investors could lose all or part of their investment.

Risks Relating to Our Business

Since we have a limited operating history and have only recently commenced revenue producing operations, it is difficult for
potential investors to evaluate our business. We formed our corporation in June 2014 and only commenced revenue producing operations
in the first quarter of 2017. From inception through December 31, 2018, we generated a total of $6.5 million of revenue, all of which was
derived primarily from the sale of lead compounds and plastics and, to a lesser extent, the sale of lead bullion, including Aqua Refined lead.
To date, our operations have primarily consisted of the development and testing of our AquaRefining process, the construction of our initial
LAB  recycling  facility  at  TRIC,  the  continuing  development  of  our  LAB  recycling  operations  at  TRIC  and  limited  revenue  producing
operations  as  we  bring  those  LAB  recycling  operations  online. Our  limited  operating  history  makes  it  difficult  for  potential  investors  to
evaluate  our  technology  or  prospective  operations. As  an  early  stage  company,  we  are  subject  to  all  the  risks  inherent  in  the  initial
organization, financing, expenditures, complications and delays in a new business, including, without limitation:

•

•

•

•

•

•

the timing and success of our plan of commercialization and the fact that we continue to experience delays in ramping up our
LAB recycling operations at TRIC;
our  ability  to  bring  modules  online  and  ramp  up  production  on  a  commercial
scale.
our  ability  to  profitably  operate  our  AquaRefining  process  on  a  commercial
scale;
our  ability  to  realize  the  expected  benefits  of  our  strategic  partnership  with  Johnson
Controls;
our  ability  to  procure  LABs  in  sufficient  quantities  at  competitive  prices;
and
our  ability  to  receive  proper  certification  from  and  meet  the  requirements  of  our  customers  regarding  the  purity  of  our
AquaRefined lead.

Investors should evaluate an investment in us in light of the uncertainties encountered by developing companies in a competitive

environment. There can be no assurance that our efforts will be successful or that we will ultimately be able to attain profitability.

Our business is dependent upon our successful implementation of novel and unproven technologies and processes and there
can  be  no  assurance  that  we  will  be  able  to  implement  such  technologies  and  processes  in  a  manner  that  supports  the  successful
commercial  roll-out  of  our  business  model. While  much  of  the  technology  and  processes  involved  in  our  lead  recycling  operations  are
widely  used  and  proven,  the AquaRefining  component  of  our  lead  recycling  operations  is  largely  novel  and  unproven. While  we  have
shown  that  our  proprietary  technology  can  produce AquaRefined  lead  on  a  small  scale,  we  have  only  recently  completed,  and  put  into
limited  operation,  the  processes  that  we  believe  will  support  the  production  of AquaRefined  lead  on  a  commercial  scale. Further,  as  we
complete our AquaRefining production line, we continue to encounter unforeseen complications that have delayed the ramping up of our
AquaRefining  modules  and  the  integration  of  our AquaRefining  process  with  the  traditional  lead  recycling  operations.  There  can  be  no
assurance  that  we  will  be  able  to  overcome  these  production  and  performance  issues  in  a  timely  manner  or  that  we  will  not  encounter
additional  unforeseen  complications  that  will  cause  further  delays  in  our  planned  commercial  roll-out  of  all  16 AquaRefining  modules
installed at TRIC and to ramp up the production of AquaRefined lead.

We will need additional financing to execute our business plan and fund operations, which additional financing may not be
available on reasonable terms or at all. As of December 31, 2018, we had total cash of $20.9 million and working capital of $11.0 million,
which gives no effect to a January 2019 public offering of our common shares from which we received approximately $9.1 million of net
proceeds. As of the date of this report, we believe that we have working capital sufficient to fund our current plan of operations at TRIC
over  the  next  twelve  months. However,  we  will  require  additional  capital  in  order  to  increase  production  of AquaRefined  lead  at  TRIC
beyond that planned for 16 modules, to work with Johnson Controls on equipment integration and licensing to third parties, to fund working
capital needs related to the ramp-up of our operations and to fund our continued losses from operations until such time as we are able to
achieve  positive  cash  flow  from  operations. There  can  be  no  assurance  that  we  will  be  able  to  acquire  the  necessary  funding  on
commercially reasonable terms or at all.  There can also be no assurance we will be able to conclude the proposed development agreement
with  Johnson  Controls. We  intend  to  seek  additional  funds  through  various  financing  sources,  including  the  sale  of  our  equity  and  debt
securities,  licensing  fees  for  our  technology,  joint  ventures  with  capital  partners  and/or  project  financing  of  our  recycling  facilities.
However, there can be no assurance that such funds will be available on commercially reasonable terms, if at all. If  such  funding  is  not
available  on  satisfactory  terms,  we  may  be  unable  to  further  pursue  our  business  plan  and  we  may  be  unable  to  continue  operations,  in
which case you may lose your entire investment.

We have assigned the operation and management of our TRIC facility and any future facilities we may develop directly to Veolia,
and there can be no assurance that we will realize the intended benefits of our relationship with Veolia or, if we do, that we will not
develop a dependency on Veolia. In February 2018, we entered into an Operations, Management and Maintenance Agreement

12

 
 
with  Veolia  North  America  Regeneration  Services,  LLC,  or  Veolia.  Pursuant  to  the  Agreement,  Veolia  will  provide  operations,
maintenance and management services at our AquaRefining facility at TRIC. We expect Veolia to contribute operational and technological
expertise  and  organizational  capabilities  in  aqueous  based  process  chemistries  and  electrolysis  along  with  taking  on  responsibility  for
operations,  supply  chain,  offtake  and  management  of  the  plant.  While  we  believe  the  Agreement  will  allow  us  to  leverage  Veolia’s
operations  and  process  engineering  expertise  and  supply  chain,  offtake  and  waste  stream  buying  power  and  expertise,  there  can  be  no
assurance that we will realize the expected benefits our agreement with Veolia. In addition, we have agreed to grant Veolia the right of first
refusal to operate and manage any future facilities developed or licensed by us. It is our expectation that Veolia will serve as our go-to-
market execution partner to staff and manage AquaRefining facilities with mutually agreed performance metrics for Aqua Metals and our
partners. In the event, Veolia is successful in operating and managing the recycling facilities developed by us and our licensees, there is a
risk that we will become dependent on Veolia for the operational and managerial expertise and labor.  There can be no assurance that Veolia
will  be  able  successfully  in  managing  our  recycling  facilities  and  those  of  our  partners. There  can  also  be  no  assurance  that  Veolia  will
continue to provide such services in the future, in which case the loss of Veolia as our service provider could cause a serious disruption in
our operations.

There  can  be  no  assurance  that  we  will  be  able  to  negotiate  a  long-term  agreement  with  Veolia,  in  which  case  we  may  lose
Veolia’s services at the end of the two-year term of our initial agreement. Our Operations, Management and Maintenance Agreement with
Veolia is for a two-year term. Pursuant to the Agreement, we have agreed to enter into good faith negotiations for a longer-term version of
the Agreement  that  will  provide  for  Veolia’s  management  and  operation  of  the  TRIC  facility  for  a  ten-year  term.  We  have  agreed  with
Veolia to use our good faith commercial best-efforts to conclude negotiations for the long-term agreement by September 30, 2020. We have
also agreed to enter into good faith negotiations with Veolia for a long-term agreement concerning Veolia’s participation in the commercial
licensing and management of our future AquaRefining facilities developed by licensees of Aqua Metals. We have agreed with Veolia to use
our  good  faith  commercial  best-efforts  to  conclude  negotiations  for  the  long-term  licensing  and  future  facilities  agreement  by  June  30,
2020. There  can  be  no  assurance  that  we  will  be  able  to  negotiate  and  conclude  a  definitive  long-term  agreement  with  Veolia  on
commercially reasonable terms, or at all. If we are unable to conclude long-term agreements with Veolia by the designated dates, it is likely
that we will lose Veolia as the operator and manager of our TRIC facility.

We are subject to restrictive debt covenants that may limit our ability to run our business, finance our capital needs and pursue
business opportunities and activities. As of the date of this report, we are indebted to Green Bank for approximately $9.5 million, which is
secured  by  liens  on  substantially  all  of  our  assets. The  credit  agreement  governing  such  indebtedness  contains  covenants  that  limit  our
ability to take certain actions. These covenants could limit our ability to finance our future operations and capital needs and our ability to
pursue business opportunities and activities that may be in our interest. If we breach any of these covenants, the debt holder could declare a
default under the credit agreement, in which case all of the indebtedness may then become immediately due and payable. If the debt under
the credit agreement is accelerated, we may not have, or be able to obtain, sufficient funds to make these accelerated payments. In addition,
since all of the indebtedness to Green Bank is secured by substantially all of our assets, a default under the credit facility could enable the
debtholder to foreclose on its security interest and attempt to seize our assets. The affirmative and negative debt covenants could materially
adversely impact our ability to operate and finance our business. In addition, our default under any of these covenants could subject us to
accelerated debt payments or foreclosure proceedings that could threaten our ability to continue as a going concern.

In the event of the acceleration of the Green Bank loan, we will need additional financing to satisfy our obligations under the
loan, which additional financing may not be available on reasonable terms or at all. As noted above, as of the date of this report, we are
indebted to Green Bank for approximately $9.5 million. The credit agreement governing such indebtedness contain various affirmative and
negative covenants and if we breach any of these covenants, the debt holder could declare a default under the credit agreement, in which
case all of the indebtedness may then become immediately due and payable. If the debt under the credit agreement is accelerated, we may
not have sufficient funds to make the accelerated payments, in which case we would be required to seek additional funds through various
financing sources, most likely through the sale of our equity or debt securities. However, there can be no assurance that such funds will be
available  on  commercially  reasonable  terms,  if  at  all. Further,  any  sale  of  our  equity  or  equity-linked  securities  will  result  in  additional
dilution to our stockholders.

Our  outstanding  debt  may  make  it  difficult  for  us  obtain  additional  financing  using  our  future  operating  cash  flow.  We
currently owe approximately $9.5 million to Green Bank as of the date of this report. Such indebtedness could limit our ability to borrow
additional funds to fund operations or expansion or increase the cost of any such borrowing, or both. Our inability to conduct additional
debt financing could:

•

•

•

limit  our  flexibility  in  developing  our  business  operations  and  planning  for,  or  reacting  to,  changes  in  our
business;
increase our vulnerability to, and reduce our flexibility to respond to, general adverse economic and industry conditions;
and
place  us  at  a  competitive  disadvantage  as  compared  to  our  competitors  that  are  not  as  highly
leveraged.

Any of these or other consequences or events could have a material adverse effect on our ability to finance our business and our operations.

13

We may be required to pay up to $2.0 million of key-man payments as the result of the resignations of our chief executive

officer and chief operating officer. On April 19, 2018, Stephen Clarke resigned as our president and chief executive officer and on
December 3, 2018 Selwyn Mould resigned as our chief operating officer.  As a result of their resignations, we may be obligated to pay up to
$2 million to Johnson Controls, payable, at our option, in cash or shares of our common stock, unless Johnson Controls approves the
successor to Mr. Clarke and Mr. Mould.  Following the December 3, 2018 resignation of Mr. Mould, Johnson Controls delivered to us its
claim for payment of the key-man penalties for Messrs. Clarke and Mould in the total amount of $2 million. We believe, however, that
Johnson Controls’ demand was premature as it had not considered the adequacy of the replacements for Mr. Clarke or Mr. Mould and that
any such claim can be asserted only after their replacements have been appointed and considered in good faith. We intend to dispute
Johnson Controls’ claims for the key-man payments, however there can be no assurance we will be successful in doing so. If we are
unsuccessful in doing so, we may be obligated to pay Johnson Controls up to $2 million payable in cash or, at our option, shares of our
common stock having a market value of $2 million.

Our business model is new and has not been proven by us or anyone else. We are engaged in the business of producing recycled
lead through a novel and unproven technology. While the production of recycled lead is an established business, to date all recycled lead
has  been  produced  by  way  of  traditional  smelting  processes. To  our  knowledge,  no  one  has  successfully  produced  recycled  lead  in
commercial  quantities  other  than  by  way  of  smelting.  In  addition,  our  lead  recycling  production  line  at  TRIC  is  the  first-of-its-kind  and
neither we nor anyone else has ever successfully built a production line that commercially recycles LABs without smelting. While we have
commenced  limited  lead  recycling  operations  at  our  TRIC  facility,  through  December  31,  2018  all  of  our  revenues  have  been  derived
primarily from the sale of lead compounds and plastics and to a lesser extent, the sale of lead bullion, including Aqua Refined lead. We
began shipments of lead bullion, which included AquaRefined lead in April 2018. In addition to the general risks associated with a novel
and unproven technology, our business model is subject to a number of related risks, including:

•

•

•

•

our  ability  to  acquire  sufficient  quantities  of  used  LABs  at  competitive
prices;
our  ability  to  produce  AquaRefined  lead  that  is  priced  competitively  with  lead  produced  by  traditional
smelting;
our ability to produce AquaRefined lead on a commercial scale and at an adequate gross profit;
and
our  ability  to  sell  our  AquaRefined  lead  at  prices  and  in  quantities  that  provide  an  adequate  net  profit  from
operations.

Further,  there  can  be  no  assurance  that  we  will  be  able  to  produce  AquaRefined  lead  in  commercial  quantities  at  a  cost  of
production  that  will  provide  us  with  an  adequate  profit  margin. The  uniqueness  of  our AquaRefining  process  and  our  production  line  at
TRIC  presents  potential  risks  associated  with  the  development  of  a  business  model  that  is  untried  and  unproven. As  of  the  date  of  this
report,  we  have  begun  to  ramp  up  our  existing AquaRefining  modules  into  commercial  operation,  however  we  continue  to  experience
performance and production issues. There can be no assurance that we will be able to overcome these production and performance issues in
a timely manner or that we will not encounter additional unforeseen complications that will cause further delays in our planned commercial
roll-out of our AquaRefining modules and the ramp up the production of AquaRefined lead.

Certain  industry  participants  may  have  the  ability  to  restrict  our  access  to  used  LABs  and  otherwise  focus  significant
competitive  pressure  on  us. We  believe  that  our  primary  competition  will  come  from  operators  of  existing  smelters  and  other  parties
invested  in  the  existing  supply  chain  for  smelting,  both  of  which  may  resist  the  change  presented  by  our  AquaRefining  process.
Competition from such incumbents may come in the form of restricted access to used LABs. We believe that LAB manufacturers who also
maintain  their  own  smelting  operations  control  a  significant  part  of  the  market  for  used  LABs. We  will  require  access  to  used  LABs  at
market prices in order to carry out our business plan. If those LAB manufacturers and others involved in the reverse supply chain for used
LABs attempt to restrict our access to used LABs, that may adversely affect our prospects and future growth. There can be no assurance
that we will be able to effectively withstand the pressures applied by our competition.

Even if we are successful in recycling lead using our processes, there can be no assurance that the AquaRefined lead will meet
the certification and purity requirements of our potential customers. A key component of our business plan is to produce recycled lead
through our AquaRefining process of the highest purity (at least 99.99% pure lead), which we refer to as AquaRefined lead.  We believe
that our AquaRefined lead will provide us with a revenue premium over the market price of lead on the London Metal Exchange, or LME,
and, more importantly, our ability to produce AquaRefined lead will be vital to confirming the efficacy and relevancy of our proprietary
technology. Our customers will require that our AquaRefined lead meet certain minimum purity standards and, in all likelihood, require
independent assays to confirm the lead’s purity. As of the date of this report, we have produced limited quantities of AquaRefined lead and
in  November  2018  Johnson  Controls  confirmed  its  approval  of  the  purity  of  our AquaRefined  lead  by  providing  to  us  official  vendor
approval  to  receive  finished  lead  at  its  manufacturing  facilities. However,  we  have  not  produced  AquaRefined  lead  in  commercial
quantities  and  there  can  be  no  assurance  that  we  will  be  able  to  do  so  or,  if  we  are  able  to  produce AquaRefined  lead  in  commercial
quantities, that such lead will continue to meet the required purity standards of our customers. If we are unable to commercially produce
AquaRefined lead that meets the purity standards established by our customers, our entire business plan may be invalidated and you may
suffer the loss of your entire investment.

While we have been successful in producing AquaRefined lead in small volumes, there can be no assurance that we will be able

to replicate the process, along with all of the expected economic advantages, on a large commercial scale either for us or our

14

prospective licensees. As of the date of this report, our commercial operations have primarily involved the production of lead compounds
and plastics from recycled LABs and, in April 2018, we commenced the limited production of lead bullion, including AquaRefined lead.
While we believe that our development, testing and limited production to date has validated the concept of our AquaRefining process, the
limited nature of our operations to date are not sufficient to confirm the economic returns on our production of recycled lead. There can be
no assurance that the commencement of commercial production of AquaRefined lead at our TRIC facility will not incur unexpected costs
or setbacks that might restrict the desired scale of our intended operations or that we will be to produce AquaRefined lead in commercial
quantities at a cost of production that will provide us with an adequate profit margin.

We have completed the construction of our initial LAB recycling facility at TRIC, however we have been delayed in the ramping
up of our lead recycling operations at TRIC and we may encounter further delays. We  completed  the  construction  of  our  initial  LAB
recycling facility at TRIC in August 2016 and commenced the limited production of recycled lead in the first quarter of 2017. However, as
of the date of this report, our commercial operations have primarily involved the production of lead compounds and plastics from recycled
LABs  and  we  only  recently  commenced  the  limited  commercial  production  of  AquaRefined  lead.  However,  we  have  encountered
production and performance issues that have impaired and delayed our ability to ramp up the production of AquaRefined lead. There can
be no assurance that we will be able to overcome these production and performance issues in a timely manner.  In addition, since our lead
recycling production line at TRIC is the first-of-its-kind, neither we nor anyone else has ever built a facility of this nature and there can be
no assurance that we will not experience additional operational delays and issues, including significant downtime from time to time, as we
progress  into  the  commercial  production  of  AquaRefined  lead. There  can  be  no  assurance  that  the  commencement  of  commercial
AquaRefining operations at our TRIC facility will not incur unexpected costs or hurdles that might restrict the desired scale of our intended
operations or negatively impact our projected gross profit margin.

Our business may be negatively affected by labor issues and higher labor costs. Our ability to maintain our workforce depends
on  our  ability  to  attract  and  retain  new  and  existing  employees. As  of  the  date  of  this  report,  none  of  our  employees  are  covered  by
collective  bargaining  agreements  and  we  consider  our  labor  relations  to  be  acceptable.  However,  we  could  experience  workforce
dissatisfaction which could trigger bargaining issues, employment discrimination liability issues as well as wage and benefit consequences,
especially during critical operation periods. We could also experience a work stoppage or other disputes which could disrupt our operations
and  could  harm  our  operating  results. In  addition,  legislation  or  changes  in  regulations  could  result  in  labor  shortages  and  higher  labor
costs. There can be no assurance that we may not experience labor issues that negatively impact our operations or results of operations.

Our  intellectual  property  rights  may  not  be  adequate  to  protect  our  business. As  of  the  date  of  this  report,  we  have  secured
granted/allowed  patents  in  the  following  countries/regions:  U.S.  (9837689,  allowed  14/957026),  Canada  (2930945),  China  (105981212),
Europe  (3072180),  Eurasia  (allowed  201691047),  South  Africa  (2016-04083),  Korea  (101739414,  101882932,  101926033),  Japan
(6173595), Mexico (357027), OAPI (17808), Ukraine (118037), and Australia (2014353227, 2015350562).

We also have further patent applications pending in the United States and numerous corresponding patent applications pending in
20 additional jurisdictions relating to certain elements of the technology underlying our AquaRefining process and related apparatus and
chemical  formulations. However, no assurances can be given that any patent issued, or any patents issued on our current and any future
patent  applications,  will  be  sufficiently  broad  to  adequately  protect  our  technology.  In  addition,  we  cannot  assure  you  that  any  patents
issued now or in the future will not be challenged, invalidated, or circumvented.

Even patents issued to us may not stop a competitor from illegally using our patented processes and materials. In such event, we
would  incur  substantial  costs  and  expenses,  including  lost  time  of  management  in  addressing  and  litigating,  if  necessary,  such  matters.
Additionally,  we  rely  upon  a  combination  of  trade  secret  laws  and  nondisclosure  agreements  with  third  parties  and  employees  having
access to confidential information or receiving unpatented proprietary know-how, trade secrets and technology to protect our proprietary
rights  and  technology. These  laws  and  agreements  provide  only  limited  protection. We  can  give  no  assurance  that  these  measures  will
adequately protect us from misappropriation of proprietary information.

Our processes may infringe on the intellectual property rights of others, which could lead to costly disputes or disruptions. The
applied  science  industry  is  characterized  by  frequent  allegations  of  intellectual  property  infringement. Though  we  do  not  expect  to  be
subject to any of these allegations, any allegation of infringement could be time consuming and expensive to defend or resolve, result in
substantial  diversion  of  management  resources,  cause  suspension  of  operations  or  force  us  to  enter  into  royalty,  license,  or  other
agreements  rather  than  dispute  the  merits  of  such  allegation. If  patent  holders  or  other  holders  of  intellectual  property  initiate  legal
proceedings, we may be forced into protracted and costly litigation. We may not be successful in defending such litigation and may not be
able to procure any required royalty or license agreements on acceptable terms or at all.

Our business strategy includes licensing arrangements and entering into joint ventures and strategic alliances, however as of
the  date  of  this  report  we  have  no  such  agreements  in  place  and  there  can  be  no  assurance  we  will  be  able  to  do  so. Failure  to
successfully integrate such licensing arrangements, joint ventures, or strategic alliances into our operations could adversely affect our
business. We propose to commercially exploit our AquaRefining process, in part, by licensing our technology to third parties and entering
into joint ventures and strategic relationships with parties involved in the manufacture and recycling of LABs, including Johnson

15

Controls,  among  others. However,  as  of  the  date  of  this  report,  we  have  not  entered  into  any  such  licensing,  joint  venture  or  strategic
alliance agreements, apart from our equipment supply agreement with Johnson Controls, and there can be no assurance that we will be able
to  do  so  on  terms  that  benefit  us,  if  at  all. In  addition,  licensing  programs,  joint  ventures  and  strategic  alliances  may  involve  significant
other risks and uncertainties, including distraction of management’s attention away from normal business operations, insufficient revenue
generation  to  offset  liabilities  assumed  and  expenses  associated  with  the  transaction,  and  unidentified  issues  not  discovered  in  our  due
diligence process, such as product quality, technology issues and legal contingencies. In addition, we may be unable to effectively integrate
any such programs and ventures into our operations. Our operating results could be adversely affected by any problems arising during or
from any licenses, joint ventures or strategic alliances.

There  can  be  no  assurance  that  we  will  be  able  to  negotiate  our  key  agreement  with  Johnson  Controls  on  commercially
reasonable terms, or at all. In February 2017, we entered into a series of agreements with Johnson Controls, including an equipment supply
agreement  pursuant  to  which,  among  other  things,  we  agreed  to  work  with  Johnson  Controls  on  the  development  of  a  program  for  the
conversion  of  Johnson  Controls  and  certain  strategic  partners  of  Johnson  Controls’  existing  lead  smelters  throughout  North  and  South
America, China and Europe to a lead recycling process utilizing our AquaRefining technology and equipment, know-how and services. The
equipment supply agreement discusses the development of the conversion program in general terms and contemplates that the parties will
enter into a definitive development program agreement that is based on the general terms set forth in the equipment supply agreement and
provides more detailed terms and conditions, including the economic obligations and rights of each party.  We have agreed not to license
our AquaRefining technology and equipment to third parties in the aforementioned regions until such time as we and Johnson Controls have
agreed on certain matters relating to the initial conversion of a Johnson Controls facility.  Johnson Controls and we have agreed to use good
faith,  commercial  best-efforts  to  conclude  the  discussion  and  negotiation  of  the  development  program  agreement  no  later  than April  30,
2019, and to enter into a definitive development program agreement no later than June 30, 2019. The equipment supply agreement may be
terminated by either party upon 60 days’ prior written notice if the parties have not entered into the development program agreement by
June 30, 2019. There can be no assurance that we will be able to negotiate and conclude a definitive development program agreement with
Johnson Controls on commercially reasonable terms, or at all.

We are dependent on a limited number of suppliers of certain materials used in our AquaRefining process and our inability to
obtain these materials as and when needed could cause a material disruption in our operations. Our AquaRefining process involves a
significant number of elements, chemicals, solvents and other materials, in addition to used LABs. There are a limited number of suppliers
of certain materials used in our AquaRefining process and we have no agreements in place for our supply of such materials. Our ability to
conduct  our AquaRefining  process  on  a  commercial  scale  will  depend  significantly  on  obtaining  timely  and  adequate  supply  of  these
materials on competitive terms. Our inability to source these materials on a timely and cost-efficient manner could interrupt our operations,
significantly limit our revenue sales and increase our costs. This factor could also impair our ability to meet our commitments to supply our
customers. Our inability to obtain these materials as and when needed could cause a material disruption in our operations.

If  we  are  unable  to  manage  future  expansion  effectively,  our  business,  operations  and  financial  condition  may  suffer
significantly, resulting in decreased productivity. If our AquaRefining process proves  to  be  commercially  viable,  growth  and  expansion
activities could place a significant strain on our managerial, administrative, technical, operational and financial resources. Our organization,
procedures and management may not be adequate to fully support the expansion of our operations or the efficient execution of our business
strategy. If we are unable to manage future expansion effectively, our business, operations and financial condition may suffer significantly,
resulting in decreased productivity.

We may experience significant fluctuations in raw material prices and the price of our principal product, either of which could
have a material adverse effect on our liquidity, growth prospects and results of operations. Used LABs are our primary raw material and
we believe that in recent years the cost of used LABs has been volatile at times. In addition, we believe that the cost of used LABs can be
seasonal, with prices trending lower in the winter months (as automobile owners increase their purchase of new LABs, thereby putting a
greater  number  of  used  LABs  on  the  market)  and  trend  higher  in  the  spring  (as  the  purchase  of  new  LABs,  and  supply  of  used  LABs,
decreases). Our principal product, recycled lead, has also experienced price volatility from time to time as well. For example, the market
price of lead on the LME during 2018 ranged from approximately $1,900 to $2,700 per tonne. While we intend to pursue supply and tolling
arrangements  as  appropriate  to  offset  any  price  volatility,  the  volatile  nature  of  prices  for  used  LABs  and  recycled  lead  could  have  an
adverse impact on our liquidity, growth prospects and results of operations.

Global economic conditions could negatively affect our prospects for growth and operating results. Our  prospects  for  growth
and operating results will be directly affected by the general global economic conditions of the industries in which our suppliers, partners
and  customer  groups  operate. We believe that the market price of our principal product, recycled lead, is relatively volatile and reacts to
general  global  economic  conditions.  Lead  prices  decreased  from  $2,139  per  tonne  on  May  5,  2015  to  a  low  of  $1,554  per  tonne  on
November 23, 2015 because of fluctuations in the market. A month later, the price per tonne increased back up to $1,801 per tonne; the
price per tonne was $2,008 on December 31, 2018. Our business will be highly dependent on the economic and market conditions in each
of the geographic areas in which we operate. These conditions affect our business by reducing the demand for LABs and decreasing the
price of lead in times of economic down turn and increasing the price of used LABs in times of increasing demand of LABs and

16

recycled  lead. There can be no assurance that global economic conditions will not negatively impact our liquidity, growth prospects and
results of operations.

We are subject to the risks of conducting business outside the United States. A part of our strategy involves our pursuit of growth
opportunities in certain international market locations. We intend to pursue licensing or joint venture arrangements with local partners who
will be primarily responsible for the day-to-day operations. Any expansion outside of the US will require significant management attention
and financial resources to successfully develop and operate any such facilities, including the sales, supply and support channels, and we
cannot assure you that we will be successful or that our expenditures in this effort will not exceed the amount of any resulting revenues.
Our international operations expose us to risks and challenges that we would otherwise not face if we conducted our business only in the
United States, such as:

U.S. Government regulation and environmental, health and safety concerns may adversely affect our business. Our operations
in the United States will be subject to the Federal, State and local environmental, health and safety laws applicable to the reclamation of
lead  acid  batteries. Our  facilities  will  have  to  obtain  environmental  permits  or  approvals  to  operate,  including  those  associated  with  air
emissions, water discharges, and waste management and storage. We may face opposition from local residents or public interest groups to
the installation and operation of our facilities. In addition to permitting requirements, our operations are subject to environmental health,
safety  and  transportation  laws  and  regulations  that  govern  the  management  of  and  exposure  to  hazardous  materials  such  as  the  lead  and
acids  involved  in  battery  reclamation. These  include  hazard  communication  and  other  occupational  safety  requirements  for  employees,
which may mandate industrial hygiene monitoring of employees for potential exposure to lead. Failure to comply with these requirements
could subject our business to significant penalties (civil or criminal) and other sanctions that could adversely affect our business.

In  the  event  we  are  unable  to  present  and  operate  our  AquaRefining  process  and  operations  as  safe  and  environmentally
responsible,  we  may  face  opposition  from  local  governments,  residents  or  public  interest  groups  to  the  installation  and  operation  of  our
facilities.

The  development  of  new  AquaRefining  facilities  by  us  or  our  partners  or  licensees,  and  the  expansion  of  our  operations  at
TRIC, will depend on our ability to acquire necessary permits and approvals, of which there can be no assurance. As noted above, our
AquaRefining facilities will have to obtain environmental permits or approvals to operate, including those associated with air emissions,
water  discharges,  and  waste  management  and  storage. In  addition,  we  expect  that  our  planned  expansion  of AquaRefining  operations  at
TRIC  will  require  additional  permitting  and  approvals. Failure  to  secure  (or  significant  delays  in  securing)  the  necessary  permits  and
approvals  could  prevent  us  and  our  partners  and  licensees  from  pursuing  additional AquaRefining  facilities  or  expanding  operations  at
TRIC,  and  otherwise  adversely  affect  our  business,  financial  results  and  growth  prospects. Further,  the  loss  of  any  necessary  permit  or
approval could result in the closure of an AquaRefining facility and the loss of our investment associated with such facility.

Our business involves the handling of hazardous materials and we may become subject to significant fines and other liabilities
in the event we mishandle those materials. The nature of our operations involves risks, including the potential for exposure to hazardous
materials  such  as  lead,  that  could  result  in  personal  injury  and  property  damage  claims  from  third  parties,  including  employees  and
neighbors,  which  claims  could  result  in  significant  costs  or  other  environmental  liability. Our  operations  also  pose  a  risk  of  releases  of
hazardous  substances,  such  as  lead  or  acids,  into  the  environment,  which  can  result  in  liabilities  for  the  removal  or  remediation  of  such
hazardous substances from the properties at which they have been released, liabilities which can be imposed regardless of fault, and our
business could be held liable for the entire cost of cleanup even if we were only partially responsible. We are also subject to the possibility
that  we  may  receive  notices  of  potential  liability  in  connection  with  materials  that  were  sent  to  third-party  recycling,  treatment,  and/or
disposal  facilities  under  the  Federal  Comprehensive  Environmental  Response,  Compensation  and  Liability  Act  of  1980,  as  amended
(“CERCLA”), and comparable state statutes, which impose liability for investigation and remediation of contamination without regard

17

to fault or the legality of the conduct that contributed to the contamination, and for damages to natural resources. Liability under CERCLA
is retroactive, and, under certain circumstances, liability for the entire cost of a cleanup can be imposed on any responsible party. Any such
liability could result in judgments or settlements that restrict our operations in a manner that materially adversely effects our operations and
could result in fines, penalties or awards that could materially impair our financial condition and even threaten our continued operation as a
going concern.

We will be subject to foreign government regulation and environmental, health and safety concerns that may adversely affect
our business. As our business expands outside of the United States, our operations will be subject to the environmental, health and safety
laws of the countries where we do business, including permitting and compliance requirements that address the similar risks as do the laws
in  the  United  States,  as  well  as  international  legal  requirements  such  as  those  applicable  to  the  transportation  of  hazardous  materials.
Depending on the country or region, these laws could be as stringent as those in the US, or they could be less stringent or not as strictly
enforced. In some countries in which we are interested in expanding our business, such as Mexico and China, the relevant environmental
regulatory and enforcement frameworks are in flux and subject to change. Compliance with these requirements will cause our business to
incur costs, and failure to comply with these requirements could adversely affect our business.

In  the  event  we  are  unable  to  present  and  operate  our  AquaRefining  process  and  operations  as  safe  and  environmentally
responsible,  we  may  face  opposition  from  local  governments,  residents  or  public  interest  groups  to  the  installation  and  operation  of  our
facilities.

Risks Related to Owning Our Common Stock

A securities class action lawsuit and shareholder derivative lawsuit are pending against us and could have a material adverse
effect  on  our  business,  results  of  operations  and  financial  condition. A  putative  consolidated  class  action  lawsuit  and  shareholder
derivative  lawsuit  are  pending  against  us  and  certain  of  our  directors  and  officers. These  lawsuits  may  divert  financial  and  management
resources that would otherwise be used to benefit our operations. Although we deny the material allegations in the lawsuits and intend to
defend ourselves vigorously, defending the lawsuits could result in substantial costs.  No assurances can be given that the results of these
matters  will  be  favorable  to  us. An  adverse  resolution  of  any  of  these  lawsuits  could  have  a  material  adverse  effect  on  our  results  of
operations and financial condition. In addition, we may be the target of securities-related litigation in the future, both related and unrelated
to  the  existing  class  action  and  shareholder  derivative  lawsuits. Such  litigation  could  divert  our  management’s  attention  and  resources,
result in substantial costs, and have an adverse effect on our business, results of operations and financial condition.

We maintain director and officer insurance that we regard as reasonably adequate to protect us from potential claims; however, we
are responsible for meeting certain deductibles under the policies and, in any event, we cannot assure you that the insurance coverage will
adequately  protect  us  from  claims  made. Further,  as  a  result  of  the  pending  litigation  the  costs  of  insurance  may  increase  and  the
availability of coverage may decrease. As a result, we may not be able to maintain our current levels of insurance at a reasonable cost, or at
all, which might make it more difficult to attract qualified candidates to serve as executive officers or directors.

Our common stock is thinly traded and our share price has been volatile. Our common stock has traded on the Nasdaq Capital
Market, under the symbol “AQMS”, since July 31, 2015. Since that date, our common stock has at times been relatively thinly traded and
subject to price volatility. There can be no assurance that we will be able to successfully maintain a liquid market for our common shares.
The stock market in general, and early stage public companies in particular, has experienced extreme price and volume fluctuations that
have often been unrelated or disproportionate to the operating performance of such companies. If we are unable to develop and maintain a
liquid market for our common shares, you may not be able to sell your common shares at prices you consider to be fair or at times that are
convenient for you, or at all. In addition, following periods of volatility in the market price of a company's securities, litigation has often
been  brought  against  that  company  and  we  may  become  the  target  of  litigation  as  a  result  of  price  volatility. Litigation  could  result  in
substantial costs and divert our management's attention and resources from our business. This could have a material adverse effect on our
business, results of operations and financial condition.

We  are  an  “emerging  growth  company”  under  the  JOBS  Act  of  2012  and  we  cannot  be  certain  if  the  reduced  disclosure
requirements applicable to emerging growth companies will make our common stock less attractive to investors. We are an “emerging
growth  company,”  as  defined  in  the  Jumpstart  Our  Business  Startups Act  of  2012  (“JOBS Act”),  and  we  may  take  advantage  of  certain
exemptions from various reporting requirements that are applicable to other public companies that are not “emerging growth companies”
including, but not limited to:

•

•

•

•

not  being  required  to  comply  with  the  auditor  attestation  requirements  of  Section  404  of  the  Sarbanes-Oxley
Act;
reduced  disclosure  obligations  regarding  executive  compensation  in  our  periodic  reports  and  proxy
statements;
exemptions  from  the  requirements  of  holding  a  nonbinding  advisory  vote  on  executive  compensation  and  stockholder
approval of any golden parachute payments; and
extended  transition  periods  available  for  complying  with  new  or  revised  accounting
standards.

18

 
We have chosen to “opt out” of the extended transition periods available for complying with new or revised accounting standards,
but we intend to take advantage of all of the other benefits available under the JOBS Act, including the exemptions discussed above. We
cannot predict if investors will find our common stock less attractive because we may rely on these exemptions. If some investors find our
common stock less attractive as a result, there may be a less active trading market for our common stock and our stock price may be more
volatile.

We will remain an “emerging growth company until 2020, although we will lose that status sooner if our revenues exceed $1.07
billion, if we issue more than $1.07 billion in non-convertible debt in a three-year period, or if the market value of our common stock that is
held by non-affiliates exceeds $700 million as of any June 30.

Our status as an “emerging growth company” under the JOBS Act may make it more difficult to raise capital as and when we
need it. Because of the exemptions from various reporting requirements provided to us as an “emerging growth company,” we may be less
attractive to investors and it may be difficult for us to raise additional capital as and when we need it. Investors may be unable to compare
our business with other companies in our industry if they believe that our reporting is not as transparent as other companies in our industry.
If we are unable to raise additional capital as and when we need it, our financial condition and results of operations may be materially and
adversely affected.

We have not paid dividends in the past and have no plans to pay dividends. We plan to reinvest all of our earnings, to the extent
we have earnings, in order to develop our recycling centers and cover operating costs and to otherwise become and remain competitive. We
do not plan to pay any cash dividends with respect to our securities in the foreseeable future. We cannot assure you that we would, at any
time, generate sufficient surplus cash that would be available for distribution to the holders of our common stock as a dividend. Therefore,
you should not expect to receive cash dividends on our common stock.

Shares eligible for future sale may adversely affect the market for our common stock . Of the 44,354,852 shares of our common
stock outstanding as of the date of this report, approximately 40,422,488 shares are held by “non-affiliates” and are freely tradable without
restriction pursuant to Rule 144. In addition, in August 2016, we filed with the SEC a Registration Statement on Form S-3 for purposes of
registering the resale of 3,711,872 shares of restricted common stock sold to Interstate Battery in May 2016, including 3,009,625 shares of
common stock issuable to Interstate Battery upon exercise of its warrants and conversion of its convertible note, and in February 2017, we
filed with the SEC a Registration Statement on Form S-3 for purposes of registering the resale of the 939,005 shares of restricted common
stock  we  sold  to  Johnson  Controls  in  February  2017. Both  registration  statements  were  declared  effective  by  the  SEC  and  the  shares
registered thereunder are eligible for sale without restriction. Any substantial sale of our common stock pursuant to Rule 144 or pursuant to
any resale prospectus may have a material adverse effect on the market price of our common stock.

Our  charter  documents  and  Delaware  law  may  inhibit  a  takeover  that  stockholders  consider  favorable.  Provisions  of  our
certificate of incorporation and bylaws and applicable provisions of Delaware law may delay or discourage transactions involving an actual
or  potential  change  in  control  or  change  in  our  management,  including  transactions  in  which  stockholders  might  otherwise  receive  a
premium  for  their  shares,  or  transactions  that  our  stockholders  might  otherwise  deem  to  be  in  their  best  interests. The  provisions  in  our
certificate of incorporation and bylaws:

•

•

•

•

•

call 

stockholder

limit  who  may 
meetings;
do  not  permit  stockholders  to  act  by  written
consent;
do  not  provide  for  cumulative  voting
rights;
establish an advance notice procedure for stockholders' proposals to be brought before an annual meeting, including proposed
nominations of persons for election to our board of directors, and
provide that all vacancies may be filled by the affirmative vote of a majority of directors then in office, even if less than a
quorum.

In addition, Section 203 of the Delaware General Corporation Law may limit our ability to engage in any business combination
with a person who beneficially owns 15% or more of our outstanding voting stock unless certain conditions are satisfied. This restriction
lasts for a period of three years following the share acquisition. These provisions may have the effect of entrenching our management team
and  may  deprive  you  of  the  opportunity  to  sell  your  shares  to  potential  acquirers  at  a  premium  over  prevailing  prices. This  potential
inability to obtain a control premium could reduce the price of our common stock.

Our bylaws designate the Court of Chancery of the State of Delaware as the sole and exclusive forum for certain litigation that

may be initiated by our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with
the Company. Our bylaws provide that, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the
State of Delaware shall be the sole and exclusive forum for (i) any derivative action or proceeding brought on our behalf, (ii) any action
asserting a claim of breach of fiduciary duty owed by any of our directors, officers or other employees to us or our stockholders, (iii) any
action asserting a claim against us or any our directors, officers or other employees arising pursuant to any provision of the Delaware
General Corporation Law or our certificate of incorporation or bylaws, or (iv) any action asserting a claim

19

against us or any our directors, officers or other employees governed by the internal affairs doctrine. This forum selection provision in our
bylaws may limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or any our directors, officers or other
employees.

Properties

Our executive offices are presently located in  14,016 square feet of mixed office and warehouse space in McCarran, Nevada. We
lease these facilities at a lease rate of approximately $10,000 per month. The lease term began in July 2018 and expires December 31, 2021.

Our executive offices were previously located in 21,697 square feet of office and industrial space in a multi-building commercial
project  known  as  “Marina  Village”  located  in Alameda,  California.  The  lease  term  is  76  months,  commencing  February  1,  2016  and
expiring May 31, 2022. Subsequent to year end we sublet the property with the sublease commencing February 2019, and expiring May 31,
2022.

We have developed and own a 136,750 square foot LAB recycling facility on 11.73 acres of land located in TRIC, a 107,000-acre

park located nine miles east of Reno, Nevada on I-80.

Legal Proceedings

Beginning  on  December  15,  2017,  three  purported  class  action  lawsuits  were  filed  in  the  United  Stated  District  Court  for  the
Northern  District  California  against  us,  Stephen  Clarke,  Thomas  Murphy  and  Mark  Weinswig.    On  March  23,  2018,  the  cases  were
consolidated  under  the  caption In  Re:  Aqua  Metals,  Inc.  Securities  Litigation Case  No  3:17-cv-07142.  On  May  23,  2018,  the  Court
appointed lead plaintiffs and approved counsel for the lead plaintiffs.  On July 20, 2018, the lead plaintiffs filed a consolidated amended
complaint (“Amended Complaint”), on behalf of a class of persons who purchased our securities between May 19, 2016 and November 9,
2017, against us, Stephen Clarke, Thomas Murphy and Selwyn Mould.  The Amended Complaint alleges the defendants made false and
misleading  statements  concerning  our  lead  recycling  operations  in  violation  of  Section  10(b)  of  the  Securities  Exchange Act  of  1934
(“Exchange Act”)  and  Rule  10b-5  promulgated  thereunder  and  seeks  to  hold  the  individual  defendants  as  control  persons  pursuant  to
Section  20(a)  of  the  Exchange  Act.    The  Amended  Complaint  also  alleges  a  violation  of  Section  11  of  the  Securities  Act  of  1933
(“Securities Act”) based on alleged false and misleading statements concerning our lead recycling operations contained in, or incorporated
by  reference  in,  our  Registration  Statement  on  Form  S-3  filed  in  connection  with  our  November  2016  public  offering.      That  claim  is
asserted  on  behalf  of  a  class  of  persons  who  purchased  shares  pursuant  to,  or  that  are  traceable  to,  that  Registration  Statement.    The
Amended Complaint seeks to hold the individual defendants liable as control persons pursuant to Section 15 of the Securities Act.  The
Amended Complaint seeks unspecified damages and plaintiffs’ attorneys’ fees and costs. On September 18, 2018, the defendants filed a
motion to dismiss the Amended Complaint in its entirety and the plaintiff subsequently filed its opposition to the motion.  In January 2019,
the  court  notified  the  parties  that  it  will  rule  on  the  motion  to  dismiss  without  a  hearing.  We  deny  that  the  claims  in  the  Amended
Complaint have any merit and we intend to vigorously defend the action.

Beginning on February 2, 2018, five purported shareholder derivative actions were filed in the United States District Court for the
District of Delaware against us and certain of our current and former executive officers and directors, Stephen R. Clarke, Selwyn Mould,
Thomas Murphy, Mark Weinswig, Vincent DiVito, Mark Slade and Mark Stevenson.  On May 3, 2018, the cases were consolidated under
the caption In re Aqua Metals, Inc. Stockholder Derivative Litigation, Case No. 1:18-cv-00201-LPS (D. Del.). The complaints were filed by
persons claiming to be stockholders of Aqua Metals and generally allege that certain of our officers and directors breached their fiduciary
duties  to  us  by  violating  the  federal  securities  laws  and  exposing  us  to  possible  financial  liability.    The  complaints  seek  unspecified
damages and plaintiffs’ attorneys’ fees and costs.  The parties have entered into a stipulation staying the action until 30 days after a decision
on our motion to dismiss the Amended Complaint in the class action described above.  The individual defendants deny that the claims in
the shareholder derivative action have any merit and intend to vigorously defend the action.

We are not party to any other legal proceedings.  We may, from time to time, be party to litigation and subject to claims incident to
the ordinary course of business.  As our growth continues, we may become party to an increasing number of litigation matters and claims. 
The outcome of litigation and claims cannot be predicted with certainty, and the resolution of any future matters could materially affect our
future financial position, results of operations or cash flows.

Management’s Discussion and Analysis of Financial Condition and Results of Operations

General

Aqua  Metals  (NASDAQ: AQMS)  is  engaged  in  the  business  of  lead  recycling  through  its  novel,  proprietary  and  patented
AquaRefining™  technology.  AquaRefining  is  a  near  room  temperature,  water  and  organic  acid-based  process  that  greatly  reduces
environmental emissions. We believe our suite of patented and patent pending AquaRefining technologies will allow the lead-acid battery
industry  to  simultaneously  improve  the  environmental  impact  of  lead  recycling  and  scale  recycling  production  to  meet  demand.
Furthermore, our AquaRefining technologies result in high purity lead. We were formed as a Delaware corporation on June 20, 2014 and
since  our  formation,  we  have  focused  our  efforts  on  the  development  and  testing  of  our AquaRefining  process,  the  construction  of  our
initial  lead  acid  battery,  or  LAB,  recycling  facility  at  the  Tahoe-Reno  Industrial  Center,  or  TRIC,  located  in  McCarran,  Nevada  and
commercializing the AquaRefining process.

We completed the development of our first LAB recycling facility at TRIC and commenced production of battery breaking and
limited  operations  during  the  first  quarter  of  2017. The  TRIC  facility  now  produces  varying  products  for  commercial  sales  primarily
consisting  of  ingoted AquaRefined  lead,  lead  compounds,  ingoted  hard  lead  and  as  well  as  plastic. In April  2017  we  commenced  the
shipment of products for sale, consisting of lead compounds as well as plastics. In April 2018 we commenced the limited production of
lead bullion, including AquaRefined lead. In July 2018 we commenced the sale of pure AquaRefined lead in the form of two tonne blocks
and in October 2018 we commenced the sale of AquaRefined lead in the form of battery manufacturing ready ingots.  In November 2018
we received official vendor certification from Johnson Controls for our AquaRefined lead and in December 2018 we commenced shipments
directly to Johnson Controls owned and partner battery manufacturing facilities.

As of December 2017, we had installed 16 AquaRefining modules at TRIC.  To date, we have operated the first four of the 16
modules and have made continuous improvements which have led to individual modules running in a steady state producing 100Kg/hour
for  several  days  at  a  time. As  we  bring  the  modules  into  commercial  operation,  we  expect  to  continue  to  adjust  the  modules  to  further
enhance operation. Although we staffed the facility and ran one or two AquaRefining Modules on a 24x7 basis from October to December
of 2018, we are currently running one or two modules 24-hours a day, four days a week to allow safe times for some of the key work to be
completed for our contribution margin improvement projects. Subject to key work being completed in the first quarter of 2019, we intend to
re-instate  24‑hour,  seven  days  a  week,  continuous  operations  shortly  thereafter  and  scale  to  running  all  four  of  the  initial  four  modules
before bringing the next four modules on line. In addition, we believe this operational strategy will allow us to maximize lead production,
while enabling the remaining components of the plant to be synchronized in support of increased AquaRefining.  Once we are satisfied with
the  operation  of  the  first  four  modules,  additional  modules  will  be  brought  into  production. This  process  will  be  repeated  until  full
production is reached with all 16 modules. Our goal is to operate all 16 modules on a 24/7 continuous basis by the end of 2019. However,
due to the delays and unforeseen issues in the completion of the AquaRefining production line we have experienced to date, there can be no
assurance that we will not encounter additional delays and issues.

Upon  completing  and  commissioning  the  infrastructure  and  operational  improvements  already  underway  in  the  facility  which  are
intended to result in positive contribution margin for AquaRefined lead product, we will then scale the plant and bring additional modules
on line.  These infrastructure and operational improvements are expected to allow us to recover and recycle our chemical feedstock much
more efficiently thus improving our contribution margin. In December 2018, we announced that we were nearing completion of Phase One
of our two-phase capital improvement program. Specifically, electrolyte recovery is critical to achieving positive contribution margin and,
as of the date of this report, we are now conserving 67% of our target for electrolyte recovery. We expect to conserve 75% of our target for
electrolyte  recovery  when  we  complete  Phase  One  of  the  program  during  the  first  half  of  2019  and  conserve  100%  when  we  complete
Phase Two. We are already running a successful pilot program for the Phase Two solution of our capital improvement program, which,
along  with  conserving  additional  electrolyte,  should  generate  higher  lead  yields  for  our  AquaRefining  process,  further  improving
contribution margin.

Ultimately, our goal is to operate all 16 modules running on a continuous basis, however we have decided that the initial operation of
fewer  modules  continuously  will  allow  us  to  reach  full  scale  operations  in  a  more  cost-effective  manner.    In  addition,  we  believe  this
operational strategy will allow us to synchronize the remaining components of the plant in support of increased AquaRefining.  Once we
have achieved positive contribution margin and are satisfied with the operation of the first four modules and the supporting infrastructure,
additional  modules  will  be  brought  into  production.    This  process  will  be  repeated  until  full  production  is  reached  with  all  16  modules.
However, due to the delays and unforeseen operational issues we have experienced to date, there can be no assurance that we will be able
to overcome the current production and performance issues in a timely manner or that we will not encounter additional delays and issues.

Since January 1, 2018, we have engaged in the following financing transactions:

Amendments  of  Interstate  Battery  agreements. On  June  24,  2018,  we  entered  into  a  series  of  agreements  with  Interstate  Battery
International, Inc. and its wholly-owned subsidiary (“Interstate Battery”), including an amendment to the Investor Rights Agreement dated
May  18,  2016  with  Interstate  Battery  pursuant  to  which,  among  other  things,  we  agreed  to  compensate  Interstate  Battery  should  either
Stephen Clarke, our former chief executive officer, or Selwyn Mould, our former chief operating officer, no longer hold such positions or
no longer devote substantially all of their business time and attention to our company, whether as a result of resignation, death, disability or
otherwise (such an event referred to as a “key-man event”). Pursuant to the Investor Rights Agreement, we agreed to pay Interstate Battery
$2,000,000, per occurrence, if either officer was subject to a key-man event during the two years following May 18, 2016. We also agreed
to pay Interstate Battery $2,000,000 if either or both officers are subject to a key-man event during the third year following May 18, 2016.
Pursuant to the amendment to the Investor Rights Agreement, Interstate Battery agreed to waive all payments under the key-man provisions
of  the  Investor  Rights Agreement  with  respect  to  the  resignation  of  our  former  chief  executive  officer,  Stephen  Clarke.  In  addition,  the
parties agreed that we, at our option, can elect to eliminate the key-man event and all related key-man payments associated with Mr. Mould
by (i) paying Interstate Battery a one-time fee of $0.5 million, payable by us in cash and (ii) agreeing to pay Interstate Battery $2.0 million,
payable at our election in cash or shares of our common stock, should our current president, Steve Cotton no longer serve as our president
during the period ending May 18, 2019. Additionally:

• With respect to a Credit Agreement dated May 18, 2016 between us and Interstate Battery, Interstate Battery waived the

alleged breach of the Credit Agreement based on our acquisition of Ebonex IPR, Ltd.;

• We  adjusted  the  terms  of  a  warrant  to  purchase  702,247  shares  of  its  common  stock  issued  to  Interstate  Battery  in  May
2016, pursuant to which the exercise price of the warrant was decreased from $7.12 per share to $3.33 per share and the
expiration date of the warrant was extended to June 23, 2020; and
Interstate Battery agreed to provide us with more favorable pricing and payment terms under the Supply Agreement dated
May 18, 2016 pursuant to which we buy used lead acid batteries from Interstate Battery.

•

Public Offering. On June 18, 2018, we completed a public offering of 10,085,500 shares of our common stock, at the price of $2.85
per share, for gross proceeds of $28.7 million. After the payment of underwriter discounts and offering expenses we received net proceeds
of approximately $26.6 million.

In January 2019, we completed a public offering of 5,175,000 shares of our common stock, at the price of $1.90 per share, for gross

proceeds of $9.8 million. After the payment of underwriter discounts and offering expenses, we received net proceeds of approximately
$9.1 million.

Plan of Operations

Our plan of operations for the 12-month period following the date of this report, and upon the satisfactory operation of the first
four modules, is to complete the commercial roll-out of all 16 AquaRefining modules installed at TRIC and to ramp up the production of
AquaRefined lead. We may also install an additional 16 AquaRefining modules at TRIC, subject to the receipt of additional capital and any
design improvements that are recommended based on the operation of the first 16 modules.

On February 28, 2019, after engaging in extensive diligence and engineering evaluations, we signed a long-term contract with

Veolia North America Regeneration Services LLC (Veolia), to provide operations, maintenance and management services at Aqua Metals’
AquaRefining facility in McCarran, Nevada.

Veolia will contribute operational and technological expertise and organizational capabilities in aqueous based process chemistries

and electrolysis along with taking on responsibility for operations, supply chain, offtake and management of the plant. Veolia employees
will begin working onsite starting March 4, 2019 at the McCarran facility. In addition to receiving expertise and support from Veolia North
America resources overall, this Agreement provides for Veolia to relocate up to six (6) full time employees with strong operations, process
engineering, management expertise to join the Aqua Metals team at AquaRefinery in McCarran, NV. Veolia North America will take over
the primary responsibility for scaling the facility through the remainder of 2019 to CP1-16 (Commercial Plant 1, 16 AquaRefining
Modules) of capacity. The Agreement also provides for Veolia and Aqua Metals to work together to plan in 2019 and complete the
expansion of the TRIC facility to 32 AquaRefining Modules.

We are now receiving the full previously negotiated premium value for ongoing shipments of AquaRefined lead from our partner
Johnson Controls. As previously announced in October 2018, we have our ingot casting line in production, which enables us to ship our key
product in final ingot form directly to battery manufacturing facilities and be compatible with the equipment in those facilities. We are also
working with other prospective buyers in the lead industry who are seeking ultra-pure lead for both offtake diversity and an average higher
premium than we’ve negotiated with Johnson Controls. In 2019, in addition to batteries being made from AquaRefined lead, we are also
exploring non-battery products incorporating AquaRefining technologies.

Additionally, we plan to further improve the plant economics by processing a growing proportion of the metallic lead we recover
from  breaking  batteries  within  the AquaRefinery  and  have  begun  to  commission  the  third  of  our  six  kettles  in  the  refining  area.  We
anticipate the success of this planned program will unlock additional contribution margin in early 2019 by enabling us to

26

 
 
finish  a  growing  proportion  of  these  materials  in-house,  thus  realizing  a  continually  improving  margin  and  positioning  us  for  earning  a
premium later in 2019 by refining alloys in-house. We are in the process of commissioning the third of the already purchased kettles as a
key  part  of  our  project  to  enable  our  capability  to  process  this  material.  We  are  also  developing  what  we  believe  to  be  industry  leading
know-how  and  other  intellectual  property  that  we  are  making  every  effort  to  secure  and  add  to  our  suite  of  smelting-free  lead  recycling
technologies that we believe we can in turn monetize by licensing.

In parallel with our efforts to commercialize our existing AquaRefining operations and test further the premiums we can receive for
our  ultra-pure AquaRefined  lead,  our  12-month  plan  of  operations  also  includes  our  proposal  to  license  our  technology  and  to  provide
planning, engineering, technical assistance, equipment and other services in support of the addition of an AquaRefining facility to a battery
recycling facility owned by Johnson Controls. Licensing could take the form of either a co-processing arrangement whereby we operate our
technology  in  conjunction  with  an  existing  smelter  or  our  licensee  operates  directly  utilizing  our  technology.  The  proposed  work  with
Johnson  Controls  is  expected  to  produce  a  blueprint  for  further  additions  of  AquaRefining  facilities  under  a  proposed  definitive
development  agreement  with  Johnson  Controls. Pursuant  to  this  proposed  definitive  development  agreement,  we  will  collaborate  with
Johnson  Controls  for  the  deployment  of AquaRefining  technologies  within  Johnson  Controls’  and  certain  strategic  partners  of  Johnson
Controls existing lead smelters to implement a lead recycling process utilizing our proprietary AquaRefining technology and equipment,
know-how  and  services. However,  there  can  be  no  assurance  that  we  will  be  able  to  conclude  a  definitive  development  agreement  with
Johnson Controls on terms that benefit us, if at all.

Our 12-month plan of operations also includes the pursuit and evaluation of additional strategic relationships, including our recently
announced  relationship  with  Veolia  and  the  licensing  of  our  technology  and  the  provision  of  equipment  and  services  to  other  potential
strategic partners. However, there can be no assurance that we will be able to effect any of these additional partnerships in the future on
commercially reasonable terms, or at all.

Results of Operations for the Fiscal Year Ended December 31, 2018 Compared to the Fiscal Year Ended December 31, 2017

We  were  formed  on  June  20,  2014  and  did  not  commence  revenue  producing  operations  until  January  2017.  During  the  second
quarter of 2017, we began shipments of lead compounds and plastics to customers. During the second quarter of 2018, we began shipments
of lead bullion in addition to lead compounds and plastics to customers. The following table summarizes results of operations with respect
to  the  items  set  forth  below  for  the  year  ended  December  31,  2018  and  2017  together  with  the  percentage  change  in  those  items  (in
thousands).

As mentioned above, product sales, consisting of lead compounds and plastics began in April 2017. Cost of product sales consists of
all operating costs incurred at TRIC following the commencement of product sales. Costs incurred at TRIC prior to commencement of sales
are  included  in  research  and  development  costs.  Cost  of  product  sales  includes  raw  materials,  supplies  and  related  costs,  salaries  and
benefits, consulting and outside services costs, depreciation and amortization costs and insurance, travel and overhead costs.

Revenue for the year ended December 31, 2018 doubled compared to the year ended December 31, 2017. This increase is due to
increased  sales  of AquaRefined  lead  in  our  product  mix  as  well  as  having  a  full  year  of  operations  in  2018  versus  approximately  eight
months during 2017. AquaRefined lead sales comprised 16% and 9% of total revenue during the three and twelve months ended December
31,  2018,  respectively. At  full  capacity,  we  expect AquaRefined  lead  sales  to  reach  approximately  50%  of  total  revenue.  Prior  to  the
increased sales of AquaRefined lead, including during the three months ended March 31, 2018, we ran the balance of the plant at a high
level to pressure test the non-AquaRefining infrastructure and sold the constituent components of LABs, lead compounds and plastics, with
little or no additional processing.

27

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Cost of product sales remains high and can be attributed to a number of items, including but not limited to the cost of filling the
AquaRefining system with electrolyte for our AquaRefining process, greater loss of electrolyte in the process than we expect to achieve
following certain additional process improvements expected to be brought on-line over the next 12 months, increase in maintenance costs
as we continue to adjust the modules as we increase operating time and hiring and training of personnel to run continuous operations of all
16 modules in advance of reaching continuous operations. At December 31, 2018, we had 61 employees in the TRIC facility versus 41 at
December 31, 2017 due to increased level of operations and commissioning of our plant.

Research and development cost in 2017 included TRIC operating cost prior to the commencement of product sales, including the
cost  incurred  to  prepare  our  TRIC  plant  for  operations.  During  the  year  ended  December  31,  2018,  research  and  development  costs
decreased by 44% over the comparable period in 2017. The decline in research and development expense is primarily associated with the
cost of the TRIC facility being included in cost of product sales rather than research and development subsequent to the commencement of
product sales during the second quarter of 2017 as well as an overall shift to production and commercial activities by the Company.

General and administrative expense has increased for the year ended December 31, 2018 versus December 31, 2017, primarily due
to a $2.5 million accrual of key man penalties associated with our Interstate Battery Credit Agreement and Johnson Controls Investor Rights
Agreement due to the resignations of Dr. Clarke and Mr. Mould; $0.6 million increased legal fees associated with shareholder lawsuits;
$0.9 million in legal, proxy and solicitation fees associated with the efforts to address activist investors; $0.3 million in patent related legal
fees; a $0.9 million severance accrual for our former chief executive officer; a $0.9 million severance accrual for our former chief operating
officer; a net $0.4 million non-cash charge associated with modifying a warrant for 702,247 shares of common stock in connection with our
settlement agreement with Interstate Battery (see Note 13 in the Consolidated Financial Statements for a more detailed description); a $0.8
million  non-cash  write-off  of  leasehold  improvements  at  our  former  California  location;  as  well  as  other  increases  in  other  professional
fees. General and administrative expense during the year ended December 31, 2017 included a $0.6 million accrual for estimated costs to
resolve a claim of breach of a negative covenant in our convertible loan agreement with Interstate Battery.

As described in Note 6 to the Consolidated Financial Statements, in April 2017, we acquired all of the capital shares of Ebonex IPR
Limited  for  consideration  of  $2.5  million,  consisting  of  cash,  transaction  costs  and  123,776  shares  of  our  common  stock.  The  principal
asset  of  Ebonex  IPR  Limited  consisted  of  a  patent  portfolio  with  an  independent  fair  value  of  $112,000.  Included  in  the  purchase  were
certain  fixed  assets  that  have  been  determined  by  management  to  have  no  immediate  value  and  were  not  considered  in  the  valuation  of
Ebonex IPR.

Due  to  the  fair  value  of  the  patent  portfolio  being  significantly  less  than  total  consideration,  the  early  development  stage  of  the
technology acquired and the uncertainties inherent in research and development, we recorded a non-cash impairment charge of $2.4 million
during the year ended December 31, 2017.

The  following  table  summarizes  our  other  income  and  interest  expense  for  the  year  ended  December  31,  2018  and  2017  together

with the percentage change in those items (in thousands).

Interest during the year ended December 31, 2018 and 2017 relates primarily to the $5.0 million Interstate Battery convertible note
and  the  $10.0  million  notes  payable,  amortization  of  debt  issuance  costs  incurred  in  connection  with  both  of  these  notes,  as  well  as  an
accrual for the USDA guarantee fee on the $10.0 million note to Green Bank.

The note discount associated with the Interstate Battery convertible note is amortized using the effective interest method over the
three-year term of the note, maturing on May 24, 2019. Using the effective interest method results in higher expense in later periods. Thus,
non-cash interest expense associated with the note discount amortization was $0.4 million in 2017, $2.0 million in 2018 and will be $2.6
million in 2019.

As mentioned above, we did not commence revenue producing operations until January 2017. During the second quarter of 2017, we
began shipments of lead compounds and plastics to customers. Prior to that, our operations consisted of the development and limited testing
of our AquaRefining process, the development of our business plan, the raise of our working capital and the development of our initial lead
acid battery, or LAB, recycling facility near Reno, Nevada. The following table summarizes our results of operations with respect to the
items set forth below for the years ended December 31, 2017 and 2016 together with the percentage change in those items (in thousands).

As mentioned above, product sales, consisting of lead compounds and plastics began in April 2017. Cost of product sales consists of
all operating costs incurred at TRIC following the commencement of product sales. Costs incurred at TRIC prior to commencement of sales
are  included  in  research  and  development  costs.  Cost  of  product  sales  includes  raw  materials,  supplies  and  related  costs,  salaries  and
benefits, consulting and outside services costs, depreciation and amortization costs and insurance, travel and overhead costs. There are no
comparatives for the previous periods.

Research and development cost included TRIC operating cost prior to the commencement of product sales, including cost incurred to
prepare our TRIC plant for operations. During the year ended December 31, 2017, research and development costs increased by 28% over
the comparable period in 2016. At December 31, 2016, we had 30 employees in the TRIC facility and we focused on building the plant
(cost included in research and development expense). At December 31, 2017, we had 41 employees at the TRIC facility and were focused
on  recycling  lead  operations  as  well  as  continuing  to  commission  various  processes  within  the  plant  (cost  included  in  research  and
development  expense  until  product  sales  began,  at  which  point  forward  they  were  included  in  cost  of  product  sales).  The  increase  in
research and development cost during the year ended December 31, 2017 versus the prior period is due to increased level of operations and
commissioning of our plant in TRIC.

General and administrative expense was relatively consistent during the years ended December 31, 2017 and December 31, 2016.
The small increase is primarily due to our $0.6 million accrual for estimated costs to resolve a claim of breach of a negative covenant in our
convertible loan agreement with Interstate Battery.

As  described  above  and  in  Note  6  to  the  Consolidated  Financial  Statements,  in April  2017,  we  recorded  a  non-cash  impairment

charge of $2.4 million on our Ebonex IPR Limited acquisition during the year ended December 31, 2017.

The  following  table  summarizes  our  other  income  and  interest  expense  for  the  year  ended  December  31,  2017  and  2016  together

Interest during the year ended December 31, 2017 relates primarily to the $5.0 million Interstate Battery convertible note and the

$10.0 million notes payable, amortization of debt issuance costs incurred in connection with both of these notes, as well as an

accrual for the USDA guarantee fee on the $10.0 million note to Green Bank. Interest relating to the $10.0 million notes payable during the
year ended December 31, 2016 and 2015 was capitalized as part of the building cost of the TRIC facility in the amount of $0.5 million and
$0.1 million, respectively. Interest capitalization ceased upon completion of the building in November 2016.

The note discount associated with the Interstate Battery convertible note is amortized using the effective interest method over the
three-year term of the note, maturing on May 24, 2019. Using the effective interest method results in higher expense in later periods. Thus,
non-cash interest expense associated with the note discount amortization was $0.4 million in 2017.

Liquidity and Capital Resources

As  of  December  31,  2018,  we  had  total  assets  of $71.4 million  and  working  capital  of $11.0 million,  which  gives  no  effect  to  a

January 2019 public offering of our common shares from which we received approximately $9.1 million of net proceeds.

Net cash used in operating activities for the year ended December 31, 2018, 2017 and 2016 was $26.3 million, $19.0 million  and
$11.1 million, respectively. Net cash used in operating activities during each of these periods consisted primarily of our net loss adjusted
for  non-cash  items  such  as  depreciation,  amortization,  stock-based  compensation  charges,  warrant  modification  charges  (2018),  loss  on
disposal of leasehold improvements (2018) and non-cash charges related the impairment charge (2017), as well as net changes in working
capital.

Net cash used in investing activities

Net cash used in investing activities for the year ended December 31, 2018, 2017 and 2016 was $3.9 million, $9.8 million  and $29.6
million,  respectively.  Net  cash  used  in  investing  activities  during  each  of  these  periods  consists  primarily  of  purchases  of  fixed  assets
related to the build out of our TRIC recycling facility in Nevada, and, to a lesser extent, our corporate headquarters during 2016.

Net cash provided by financing activities

Net cash provided by financing activities for the year ended December 31, 2018 consisted of $26.6 million net proceeds from our
June 2018 public offering and $2.1 million net proceeds from underwriters’ exercise, in January 2018, of their overallotment option related
to our December 2017 public offering partially offset by lease and debt payments. Net cash provided by financing activities for the year
ended December 31, 2017 primarily consisted of $13.8 million net proceeds from the issuance of common stock in our December 2017
public offering, $10.5 million net proceeds from the issuance of common stock to Johnson Controls and $1.1 million proceeds from the
exercise of stock options partially offset by lease and debt payments.

Net cash provided by financing activities for the year ended December 31, 2016 primarily consisted of $21.5 million net proceeds
from the issuance of common stock in our November 2016 public offering; $9.1 million net proceeds from the issuance of common stock
to Interstate Battery and other investors through our placement agent, National Securities Corporation; and $4.9 million net proceeds from
the Interstate Battery convertible note.

As  of  the  date  of  this  report,  and  after  giving  effect  to  a  January  2019  public  offering  of  our  common  shares  from  which  we
received approximately $9.1 million of net proceeds, we believe that our working capital is sufficient to fund our current plan of operations
at TRIC over the next twelve months. However, we will require additional capital in order to increase production of AquaRefined lead at
TRIC  beyond  that  planned  for  16  modules,  and  to  fund  our  continued  losses  from  operations  until  such  time  as  we  are  able  to  achieve
positive cash flow from operations. We intend to seek additional funds through various financing sources, includin

30

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
g the sale of our equity and debt securities, licensing fees for our technology, joint ventures with capital partners and/or project financing of
our recycling facilities. However, there can be no guarantees that such funds will be available on commercially reasonable terms, if at all. If
such  financing  is  not  available  on  satisfactory  terms,  we  may  be  unable  to  further  pursue  our  business  plan  and  we  may  be  unable  to
continue operations. Additionally, Aqua Metals Reno, or AMR, was not in compliance with its the minimum debt service coverage ratio
covenant  on  its  loan  from  Green  Bank  as  of  the  fiscal  quarter  ends  between  March  31,  2017  and  December  31,  2018. AMR  received  a
waiver for the minimum debt service coverage ratio covenant for those periods. While we expect to continue to receive waivers from Green
Bank  for  non-compliance  with  such  covenant,  there  is  no  guarantee  that  we  will  receive  such  waivers.  If  Green  Bank  determines  not  to
grant us a waiver for non-compliance in the future, we would be in default of the loan and Green Bank would be able to accelerate the
payment of all amounts under the loan.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet financing arrangements.

Critical Accounting Policies and Significant Judgments and Estimates

Our management’s discussion and analysis of our financial condition and results of operations is based on our consolidated financial
statements, which have been prepared in accordance with U.S. generally accepted accounting principles, or U.S. GAAP. The preparation of
our consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets
and liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported
amounts  of  expenses  during  the  period.  Significant  items  subject  to  such  estimates  and  assumptions  include  the  carrying  amount  and
valuation  of  long-lived  assets,  the  valuation  of  conversion  features  of  convertible  debt,  valuation  allowances  for  deferred  tax  assets,  the
determination of estimated asset retirement obligations, the determination of stock option expense, and the determination of the fair value
of stock warrants issued. Our actual results could differ from these estimates under different assumptions or conditions.

While  our  significant  accounting  policies  are  more  fully  described  in  Note  2  to  the  consolidated  financial  statements  included  in
Item 8 of this Annual Report on Form 10-K, we believe that the following accounting policies are the most critical to assist stockholders
and  investors  reading  the  consolidated  financial  statements  in  fully  understanding  and  evaluating  our  financial  condition  and  results  of
operations.

Accounts receivable

We  sell  our  products  to  large  well-established  companies  and  extend  credit  without  requiring  collateral,  based  on  an  ongoing
evaluation of the customer’s business prospects and financial condition. In the event that payment of a customer’s account receivable is
doubtful, we would reserve the receivable under an allowance for doubtful accounts.

Inventory

Inventory  is  stated  as  the  lower  of  cost  or  net  realizable  value.  Inventory  cost  is  recorded  on  a  first-in,  first-out  basis  using  the
weighted  average  method.  Net  realizable  value  is  determined  as  the  estimated  selling  price  in  the  ordinary  course  of  business,  less
reasonably predictable costs of completion, disposal, and transportation.

Property and equipment

Property and equipment are stated at cost net of accumulated depreciation. Depreciation on property and equipment is calculated on
the straight-line basis over the estimated useful lives of the assets. Leasehold improvements are depreciated over the shorter of the life of
the asset or the remaining term of the lease.

Intangible and other long-lived assets

The  intangible  assets  consist  of  a  patent  application  contributed  to  us  by  five  founding  stockholders,  patent  applications  for
technology developed by us and trademark applications. The useful life of the intangible assets has been determined to be ten years and the
assets are being amortized. We periodically evaluate our intangible and other long-lived assets for indications that the carrying amount of
an asset may not be recoverable. In reviewing for impairment, we compare the carrying value of such assets to the estimated undiscounted
future cash flows expected from the use of the assets and their eventual disposition. When the estimated undiscounted future cash flows are
less than their carrying amount, an impairment loss is recognized equal to the difference between the assets’ fair value and their carrying
value.  In  addition  to  the  recoverability  assessment,  we  routinely  review  the  remaining  estimated  lives  of  our  long-lived  assets.  Any
reduction in the useful life assumption will result in increased depreciation and amortization expense in the

31

 
 
 
 
 
 
 
 
 
 
 
 
period  when  such  determination  is  made,  as  well  as  in  subsequent  periods.  We  evaluate  the  need  to  record  impairment  during  each
reporting period. No impairment has been recorded. We determined that the estimated life of the intellectual property properly reflected the
current remaining economic life of the asset.

Asset retirement obligations

We record the fair value of estimated asset retirement obligations associated with tangible long-lived assets in the period incurred.
Retirement obligations associated with long-lived assets are those for which there is an obligation for closures and/or site remediation at the
end of the assets’ useful lives. These obligations are initially estimated based on discounted cash flow estimates and are accreted to full
value  over  time  through  charges  to  operating  expense.  In  addition,  asset  retirement  costs  are  capitalized  as  part  of  the  related  asset’s
carrying value and are depreciated on a straight-line basis over the assets’ respective useful lives.

Revenue Recognition

The  Company  records  revenue  recognition  in  accordance  with  ASC  606, Revenue  from  Contracts  with  Customers.  ASC  606
provides a single comprehensive model for the recognition of revenue arising from contracts with customers and supersedes most current
revenue  recognition  guidance,  including  industry-specific  guidance.  It  requires  an  entity  to  recognize  revenue  when  the  entity  transfers
promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange
for those goods or services. ASC 606 creates a five-step model that requires entities to exercise judgment when considering the terms of
contract(s),  which  includes  (1)  identifying  the  contract(s)  with  the  customer,  (2)  identifying  the  separate  performance  obligations  in  the
contract,  (3)  determining  the  transaction  price,  (4)  allocating  the  transaction  price  to  the  separate  performance  obligations,  and  (5)
recognizing revenue as each performance obligation is satisfied. ASC 606 requires additional disclosure about the nature, amount, timing
and  uncertainty  of  revenue  and  cash  flows  arising  from  customer  contracts,  including  qualitative  and  quantitative  information  about
contracts with customers, significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a
contract.

Research and development

Research and development expenditures are expensed as incurred.

Income taxes

We  account  for  income  taxes  in  accordance  with  the  liability  method  of  accounting  for  income  taxes.  Under  the  liability  method,
deferred assets and liabilities are recognized based upon anticipated future tax consequences attributable to differences between financial
statement  carrying  amounts  of  assets  and  liabilities  and  their  respective  tax  bases.  The  provision  for  income  taxes  is  comprised  of  the
current tax liability and the changes in deferred tax assets and liabilities. We established a valuation allowance to the extent that it is more
likely than not that deferred tax assets will not be recoverable against future taxable income.

We  recognize  the  effect  of  uncertain  income  tax  positions  only  if  those  positions  are  more  likely  than  not  of  being  sustained.
Recognized  income  tax  positions  are  measured  at  the  largest  amount  that  is  greater  than  50%  likely  of  being  realized.  Changes  in
recognition or measurement are reflected in the period in which the change in judgment occurs.

Stock-based compensation

We recognize compensation expense for stock-based compensation in accordance with ASC 718 “Compensation – Stock
Compensation.” For employee stock-based awards, we calculate the fair value of the award on the date of grant using the Black-Scholes-
Merton method for stock options; the expense is recognized over the service period for awards to vest.

The estimation of stock-based awards that will ultimately vest requires judgment and to the extent actual results or updated estimates
differ from the original estimates, such amounts are recorded as a cumulative adjustment in the period estimates are revised. The Company
considers many factors when estimating expected forfeitures, including types of awards, employee class and historical experience.

We  lease  our  Alameda,  California  and  McCarran,  Nevada  spaces  under  non-cancelable  operating  leases,  expiring  in  2022  and  2021,
respectively. On  February  4,  2019,  we  entered  into  a  sublease  agreement  effective  as  of  February  1,  2019  for  the Alameda,  California
facility. The term of the sublease commenced in February 2019, and ends on May 1, 2022. The above obligations do not include partially
offsetting sublease income of approximately $1.5 million.

Capital lease obligations

We financed certain of our lab equipment purchases through the use of capital leases. The lease terms are between 24 and 36 months with
an option to purchase the asset at the end of the lease term for $1.

Convertible debt

Our convertible debt bears interest at 11% per annum and both interest and principal are due at maturity on May 25, 2019. Interest is not
convertible. See Note 10 in the accompanying notes to the consolidated financial statements for further description. In January 2019, this
note was paid in full.

Long-term debt

AMR  entered  into  a  $10,000,000  loan  with  Green  Bank  on  November  3,  2015.  The  term  of  the  loan  is  twenty-one  years.  For  the  first
twelve months only interest was payable; thereafter monthly payments of interest and principal are due. The interest rate adjusts on the first
day of each calendar quarter equal to the greater of six percent (6%) or two percent (2%) per annum above the minimum prime lending rate
charged by large U.S. money center commercial banks as published in the Wall Street Journal. See Note 12 in the accompanying notes to
the consolidated financial statements for further description.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

We  do  not  enter  into  financial  instruments  for  trading  or  speculative  purposes.  Our  cash,  cash  equivalents  and  restricted  cash
balances as of December 31, 2018 consisted of cash and cash equivalents. Our primary exposure to market risk is interest expense related to
our debt with Green Bank. The interest rate on this loan adjusts on the first day of each calendar quarter equal to the greater of six percent
(6%)  or  two  percent  (2%)  per  annum  above  the  minimum  prime  lending  rate  charged  by  large  U.S.  money  center  commercial  banks  as
published by the Wall Street Journal. We experience market risk with respect to the volatility of lead commodity prices. The purchase price
of  our  primary  raw  material  used  lead  acid  batteries  (used  LABs),  and  the  sales  price  of  our  lead-based  finished  products  are  based  on
commodity  pricing.  Due  to  the  relatively  short  turnaround  between  the  purchase  of  used  LABs  and  the  sale  of  our  finished  goods,  we
believe the risk is minimized.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and 
Stockholders of Aqua Metals, Inc. and Subsidiaries:

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Aqua Metals, Inc. and Subsidiaries (collectively the “Company”) as of
December 31, 2018 and 2017, the related consolidated statements of operations, stockholders’ equity, and cash flows , for each of the three
years in the period ended December 31, 2018, and the related notes (collectively referred to as the “financial statements”). In our opinion,
the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2018 and 2017,
and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2018, in conformity with
U.S. generally accepted accounting principles.

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. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As
part  of  our  audits  we  are  required  to  obtain  an  understanding  of  internal  control  over  financial  reporting  but  not  for  the  purpose  of
expressing  an  opinion  on  the  effectiveness  of  the  Company’s  internal  control  over  financial  reporting. Accordingly,  we  express  no  such
opinion.

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.

We have served as the Company’s auditor since 2014.

Notes to Consolidated Financial Statements 

1.

Organization and Operations

Aqua  Metals,  Inc.  (the  “Company”)  was  incorporated  in  Delaware  and  commenced  operations  on  June  20,  2014  (inception).  On
January  27,  2015,  the  Company  formed  two  wholly-owned  subsidiaries,  Aqua  Metals  Reno,  Inc.  (“AMR”)  and  Aqua  Metals
Operations,  Inc.  (collectively,  the  “Subsidiaries”),  both  incorporated  in  Delaware.  The  Company  is  engaged  in  the  business  of  lead
recycling through its patented and patent-pending AquaRefiningTM technology. Unlike smelting, AquaRefining is a room temperature,
water-based process that emits less pollution than smelting, the traditional method of lead recycling. The Company has built its first
recycling  facility  in  Nevada’s  Tahoe  Regional  Industrial  Complex  (“TRIC”)  in  McCarran,  Nevada  and  intends  to  pursue  the
development  of  additional  lead  acid  battery  recycling  facilities  based  on  the  Company’s AquaRefining  technology,  likely  through
licensing  or  joint  development  arrangements. The  Company  commenced  the  shipment  of  products  for  sale,  consisting  of  lead
compounds  and  plastics,  in April  2017,  and  through  March  31,  2018,  substantially  all  revenue  was  derived  from  the  sale  of  lead
compounds and plastics. In April 2018, the Company began shipping cast lead bullion (mixture of lead purchased to prime the kettles
and AquaRefined  lead  from  our AquaRefining  process)  blocks  in  addition  to  lead  compounds  and  plastics  and  in  June  2018,  the
Company began shipping high purity lead from its AquaRefining process.

Liquidity and Management Plans

The  Company  completed  the  development  of  its  first  LAB  recycling  facility  at  the  Tahoe  Reno  Industrial  Center  (“TRIC”)  and
commenced  production  during  the  first  quarter  of  2017.  The  TRIC  facility  produces  recycled  lead,  consisting  of  lead  compounds,
ingoted hard lead and ingoted AquaRefined lead as well as plastic.

The Company generated revenues of  $4.4 million and $2.1 million during 2018 and 2017, had no revenue in 2016, and had net losses
o f $40.3  million, $26.6  million  and $13.6  million  for  the  years  ended  December  31,  2018,  2017  and  2016,  respectively.  As  of
December 31, 2018, the Company’s cash balance was  $20.9 million. The Company believes that its working capital as of the date of
this report is sufficient to fund the commissioning and commencement of commercial operations of 16 AquaRefining modules and its
commercial  operations  at  TRIC  through,  at  least, April  2020,  assuming  the  successful  commercial  rollouts  of  the  16 AquaRefining
modules.

Summary of Significant Accounting Policies

Basis of presentation and consolidation

The accompanying consolidated financial statements include those of Aqua Metals, Inc. and its subsidiaries, after elimination of all
intercompany accounts and transactions. We have prepared the accompanying consolidated financial statements in accordance with
accounting principles generally accepted in the United States of America (“GAAP”) and pursuant to the rules and regulations of the
United States Securities and Exchange Commission (the “SEC”).

Use of estimates

The  preparation  of  the  consolidated  financial  statements  requires  management  of  the  Company  to  make  a  number  of  estimates  and
assumptions relating to the reported amount of assets and liabilities and the disclosure of contingent assets and liabilities at the date of
the  consolidated  financial  statements,  and  the  reported  amounts  of  expenses  during  the  period.  Significant  items  subject  to  such
estimates  and  assumptions  include  the  carrying  amount  and  valuation  of  long-lived  assets,  the  valuation  of  conversion  features  of
convertible debt, valuation allowances for deferred tax assets, the determination of fair value of estimated asset retirement obligations,
the determination of stock option expense and the determination of the fair value of stock warrants issued. Actual results could differ
from those estimates.

Cash and cash equivalents

The  Company  considers  all  highly  liquid  instruments  with  original  or  remaining  maturities  of  ninety  days  or  less  at  the  date  of
purchase to be cash equivalents. The Company maintains its cash balances in large financial institutions. Periodically, such balances
may be in excess of federally insured limits.

42

 
 
 
 
 
 
 
 
 
 
Restricted cash

Restricted  cash  was  comprised  of  funds  held  in  escrow  at  Green  Bank  for  the  purpose  of  paying  for  the  construction  of  the  lead
recycling  plant  building  in  McCarran,  Nevada.  As  of  December  31,  2017,  the  building  was  complete  and  the  funds  had  been
dispersed.

In November 2016, the Financial Accounting Standards Board, FASB issued Accounting Standards Update ("ASU") No. 2016-18.
The amendments in ASU 2016-18 require an entity to reconcile and explain the period-over-period change in total cash, cash
equivalents and restricted cash within its statements of cash flows rather than reconciling and explaining the period-over-period
change in total cash and cash equivalents (excluding restricted cash). The Company adopted this new ASU beginning January 1, 2018
using the required full retrospective approach. The adoption of this standard resulted in an increase in net cash used in investing
activities of $1.1 million and $10.5 million in the consolidated statements of cash flows for the year ended December 31, 2017 and
December 31, 2016, respectively. As there is no restricted cash at December 31, 2018 or 2017, there is no effect on the year ended
December 31, 2018.

Accounts receivable

The  Company  sells  its  products  to  large  well-established  companies  and  extends  credit  without  requiring  collateral,  based  on  an
ongoing evaluation of the customer’s business prospects and financial condition. In the event that payment of a customer’s account
receivable  is  doubtful,  the  Company  would  reserve  the  receivable  under  an  allowance  for  doubtful  accounts. As  of  December  31,
2018, and 2017, the Company believes that all receivables have been or will be collected and, therefore, has not created any reserve
for doubtful accounts.

Inventory

Inventory is stated as the lower of cost or net realizable value. Cost is recorded on a first-in, first-out basis using the weighted average
method.  Net  realizable  value  is  determined  as  the  estimated  selling  price  in  the  ordinary  course  of  business,  less  reasonably
predictable costs of completion, disposal, and transportation. The Company records a write-down, if necessary, to reduce the carrying
value of inventory to its net realizable value. The effect of these write-downs is to establish a new cost basis in the related inventory,
which is not subsequently written up.

Property and equipment

Property and equipment are stated at cost net of accumulated depreciation. Depreciation on property and equipment is calculated on
the straight-line basis over the estimated useful lives of the assets. Leasehold improvements are depreciated over the shorter of the life
of the asset or the remaining term of the lease.

Intangible and other long-lived assets

Intangible  assets  consist  of  a  patent  application  contributed  to  the  Company  by  five  founding  stockholders,  patent  applications  for
technology  developed  by  the  Company,  trademark  applications  and  a  patent  portfolio  acquired  during  2017.  The  useful  life  of  this
intellectual  property  has  been  determined  to  be ten  years  and  the  assets  are  being  amortized  straight-line  over  this  period.  The
Company periodically evaluates its intangible and other long-lived assets for indications that the carrying amount of an asset may not
be recoverable. In reviewing for impairment, the Company compares the carrying value of such assets to the estimated undiscounted
future  cash  flows  expected  from  the  use  of  the  assets  and  their  eventual  disposition.  When  the  estimated  undiscounted  future  cash
flows are less than their carrying amount, an impairment loss is recognized equal to the difference between the assets’ fair value and
their carrying value. In addition to the recoverability assessment, the Company routinely reviews the remaining estimated lives of its
long-lived assets. Any reduction in the useful life assumption will result in increased depreciation and

43

 
 
 
 
 
 
 
   
 
 
 
 
   
 
 
   
 
 
 
 
 
 
 
 
 
amortization expense in the period when such determination is made, as well as in subsequent periods. The Company evaluates the
need to record impairment during each reporting period. As further described in Note 6, the Company recorded an impairment of  $2.4
million in the second quarter of 2017 on its patent portfolio. As of December 31, 2018, the Company determined that the estimated
life of the Intellectual Property properly reflected the current remaining economic life of the asset.

Asset retirement obligations

The Company records the fair value of estimated asset retirement obligations associated with tangible long-lived assets in the period
incurred. Retirement obligations associated with long-lived assets are those for which there is an obligation for closures and/or site
remediation at the end of the assets’ useful lives. These obligations are initially estimated based on discounted cash flow estimates and
are accreted to full value over time through charges to operating expense. In addition, asset retirement costs are capitalized as part of
the related asset’s carrying value and are depreciated on a straight-line basis over the assets’ respective useful lives.

Revenue Recognition

The  Company  records  revenue  in  accordance  with Accounting  Standards  Codification  ("ASC")  606,  Revenue  from  Contracts  with
Customers. ASC 606 provides a single comprehensive model for the recognition of revenue arising from contracts with customers and
supersedes most current revenue recognition guidance, including industry-specific guidance. It requires an entity to recognize revenue
when  the  entity  transfers  promised  goods  or  services  to  customers  in  an  amount  that  reflects  the  consideration  to  which  the  entity
expects  to  be  entitled  in  exchange  for  those  goods  or  services. ASC  606  creates  a  five-step  model  that  requires  entities  to  exercise
judgment when considering the terms of contract(s), which includes (1) identifying the contract(s) with the customer, (2) identifying
the separate performance obligations in the contract, (3) determining the transaction price, (4) allocating the transaction price to the
separate  performance  obligations,  and  (5)  recognizing  revenue  as  each  performance  obligation  is  satisfied.  ASC  606  requires
additional  disclosure  about  the  nature,  amount,  timing  and  uncertainty  of  revenue  and  cash  flows  arising  from  customer  contracts,
including  qualitative  and  quantitative  information  about  contracts  with  customers,  significant  judgments  and  changes  in  judgments
and assets recognized from costs incurred to obtain or fulfill a contract.

Revenue is generally recognized with the delivery of the Company’s products, primarily hard lead, lead compounds and plastics, to
customers. Sales, value add, and other taxes, if any, that are collected concurrent with revenue-producing activities are excluded from
revenue  as  they  are  subsequently  remitted  to  governmental  authorities.  Incidental  items  that  are  immaterial  in  the  context  of  the
contract  are  recognized  as  expense.  Freight  and  shipping  costs  related  to  the  transfer  of  the  Company’s  products  to  customers  are
included in revenue and cost of product sales. Payment on invoices is generally due within 30 days of the invoice.

Arrangements with Multiple Performance Obligations

Contracts  with  customers  may  include  multiple  performance  obligations. A  performance  obligation  is  a  promise  in  a  contract  to
transfer a distinct good or service to the customer and is the unit of account in ASC 606. A contract’s transaction price is allocated to
each distinct performance obligation and recognized as revenue when, or as, the performance  obligation  is  satisfied.  The  Company
expects  that  many  of  our  contracts  will  have  a  single  performance  obligation  as  the  promise  to  transfer  the  individual  goods  or
services will not be separately identifiable from other promises in the contracts and therefore, not distinct. For contracts with multiple
performance  obligations,  revenue  will  be  allocated  to  each  performance  obligation  based  on  the  Company’s  best  estimate  of  the
standalone selling price of each distinct good or service in the contract. The primary method used to estimate standalone selling prices
is  based  on  prices  charged  separately  to  customers  or  expected  cost-plus  margin. At  present,  the  Company  does  not  have  any
arrangements with multiple performance obligations.

Significant Judgments

The  Company  estimates  variable  consideration  for  arrangements  where  the  transaction  price  is  not  fully  determinable  until  the
completion of yield testing. The Company estimates variable consideration at the most likely amount to which it expects to be entitled
and includes estimated amounts in revenue to the extent it is probable that a significant reversal of revenue recognized will not occur
when the uncertainty associated with the variable consideration is resolved. Adjustments to revenue is recognized in the period when
the uncertainty is resolved. To date, any adjustments to estimates have not been material.

Practical Expedients and Exemptions

The Company does not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of
one year or less and (ii) contracts for which we recognize revenue at the amount to which we have the right to invoice for services
performed.

44

 
 
 
 
 
 
 
 
 
Research and development

Research and development expenditures are expensed as incurred.

Income taxes

The Company accounts for income taxes in accordance with the liability method of accounting for income taxes. Under the liability
method,  deferred  assets  and  liabilities  are  recognized  based  upon  anticipated  future  tax  consequences  attributable  to  differences
between financial statement carrying amounts of assets and liabilities and their respective tax bases. The provision for income taxes is
comprised  of  the  current  tax  liability  and  the  changes  in  deferred  tax  assets  and  liabilities.  The  Company  establishes  a  valuation
allowance to the extent that it is more likely than not that deferred tax assets will not be recoverable against future taxable income.

The  Company  recognizes  the  effect  of  uncertain  income  tax  positions  only  if  those  positions  are  more  likely  than  not  of  being
sustained.  Recognized  income  tax  positions  are  measured  at  the  largest  amount  that  is  greater  than  50%  likely  of  being  realized.
Changes in recognition or measurement are reflected in the period in which the change in judgment occurs.

Fair value measurements

The  carrying  amounts  of  cash  and  cash  equivalents,  accounts  receivable,  inventory,  prepaid  expenses  and  other  current  assets,
accounts payable, accrued expenses, and deferred rent approximate fair value due to the short-term nature of these instruments. The
carrying value of short and long-term debt, and lease liabilities also approximates fair value since these instruments bear market rates
of interest or are calculated using market rates of interest. None of these instruments are held for trading purposes.

Fair value is defined as an exit price, representing the amount that would be received upon the sale of an asset or payment to transfer a
liability in an orderly transaction between market participants. Fair value is a market-based measurement that is determined based on
assumptions that market participants would use in pricing an asset or liability. A three-tier far value hierarchy is used to prioritize the
inputs in measuring fair value as follows:

Level 1. Quoted prices in active markets for identical assets or liabilities.

Level 2. Quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in
markets that are not active, or other inputs that are observable, either directly or indirectly.

Level 3. Significant unobservable inputs that cannot be corroborated by market data.

The  asset  or  liability’s  fair  value  measurement  within  the  fair  value  hierarchy  is  based  upon  the  lowest  level  of  any  input  that  is
significant to the fair value measurement.

There are no assets or liabilities that are measured at fair value on a recurring basis at December 31, 2018 or 2017.

Stock-based compensation

The Company recognizes compensation expense for stock-based compensation in accordance with ASC 718 “Compensation – Stock
Compensation.” For employee stock-based awards, the Company calculates the fair value of the award on the date of grant using the
Black-Scholes-Merton method for stock options; the expense is recognized over the service period for awards to vest.

The estimation of stock-based awards that will ultimately vest requires judgment and to the extent actual results or updated estimates
differ from the original estimates, such amounts are recorded as a cumulative adjustment in the period estimates are revised.

Net loss per share

Basic  net  loss  per  share  is  computed  by  dividing  net  loss  by  the  weighted  average  number  of  vested  shares  outstanding  during  the
period. Diluted net loss per share is computed by giving effect to all potential dilutive common securities, including convertible notes,
options and warrants. Potential dilutive common shares include the dilutive effect of the common stock underlying in-the-money stock
options and is calculated based on the average share price for each period using the treasury stock method. Under the treasury stock
method, the exercise price of an option and the average amount of compensation cost, if any, for future services that the Company has
not yet recognized when the option is exercised, are assumed to be used to repurchase shares in the current period.

45

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
For all periods presented in this report, convertible notes, stock options, and warrants were not included in the computation of diluted
net loss per share because such inclusion would have had an antidilutive effect.

Excluded potentially dilutive securities (1):

Segment and Geographic Information

Operating segments are defined as components of an enterprise engaging in business activities for which discrete financial information
is  available  and  regularly  reviewed  by  the  chief  operating  decision  maker  in  deciding  how  to  allocate  resources  and  in  assessing
performance. The Company views its operations and manages its business in one operating segment, and the Company operates in
only one geographic segment.

Recent accounting pronouncements

In February 2016, the FASB issued ASU 2016-2 - Leases (ASC 842), which sets out the principles for the recognition, measurement,
presentation and disclosure of leases for both parties to a contract (i.e. lessees and lessors).  The new standard requires lessees to apply
a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively
a financed purchase by the lessee. This classification will determine whether lease expense is recognized based on an effective interest
method or on a straight-line basis over the term of the lease, respectively. A lessee is also required to record a right-of-use asset and a
lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or
less will be accounted for similar to existing guidance for operating leases today.  ASC 842 supersedes

the previous leases standard, ASC 840 Leases. The standard is effective on January 1, 2019, with early adoption permitted. The new
standard  requires  a  modified  retrospective  transition  approach  for  all  leases  existing  at,  or  entered  into  after,  the  date  of  initial
application,  with  an  option  to  use  certain  transition  relief.  In  July  2018,  the  FASB  issued ASU  No.  2018-11,  Leases  (Topic  842):
Targeted Improvements, which amends ASC Topic 842 to provide another transition method, allowing a cumulative effect adjustment
to the opening balance of retained earnings during the period of adoption. The Company has two longer term office leases and a few
small  equipment  leases. At  January  1,  2019,  the  Company  will  record  a  lease  liability  equal  to  the  present  value  of  future  lease
payments not yet paid on each of these leases and an asset for its right to use the underlying assets, net of any previously recorded
impairment. The effect of the adoption of this standard is an increase in lease liabilities of $1.6 million offset by an increase in assets
of the same amount.

There were no other recent accounting pronouncements or changes in accounting pronouncements during the year ended December
31, 2018 that are of significance or potential significance to the Company.

Revenue recognition

The Company generates revenues by recycling lead acid batteries (“LABs”) and selling the recovered lead to its customers. Primary
components  of  the  recycling  process  include  sales  of  recycled  lead  consisting  of  lead  compounds,  ingoted  hard  lead  and  ingoted
AquaRefined lead as well as plastics. The Company commenced the shipment of products for sale, consisting of lead compounds and
plastics, in April 2017, and through March 31, 2018, all revenue was derived from the sale of lead compounds and plastics. In April
2018,  the  Company  began  shipping  lead  bullion  in  addition  to  lead  compounds  and  plastics. In  June  2018,  the  Company  began
shipping high purity lead from its AquaRefining process.

Revenue from products transferred to customers at a single point in time with the delivery of the Company’s products to customers
accounted for 100% of our revenue during the years ended December 31, 2018 and 2017.

Depreciation  expense  was $3.2  million, $2.9  million  and $0.7  million  for  the  years  ended  December  31,  2018,  2017  and  2016,
respectively.  The  building  is  a  136,750  square  foot  lead  acid  battery  recycling  plant  being  built  in  McCarran,  Nevada.  Equipment
under construction is primarily AquaRefining modules manufactured by the Company to be used in the McCarran, Nevada recycling
plant.

Certain costs necessary to make the recycling facility ready for its intended use have been capitalized, including interest expense on
notes  payable.  Capitalized  interest  totaled $0.5  million  and $0.1  million  for  the  years  ended  December  31,  2016  and  2015,
respectively. Capitalization of interest ceased upon completion of the building in early November 2016.

The  Company  has  financed  certain  of  its  lab  equipment  purchases  through  the  use  of  capital  leases.  The  lease  terms  are  generally
between 24  and 36  months  with  an  option  to  purchase  the  asset  at  the  end  of  the  lease  for $1. Total lab equipment included in the
above table at December 31, 2018 subject to capital leases is $0.4 million less accumulated depreciation of $0.2 million resulting in
net fixed assets under capital lease of $0.2 million. Total lab equipment included in the above table at December 31, 2017 subject to
capital leases was $0.4  million  less  accumulated  depreciation  of $0.1 million resulted in net fixed assets under capital lease of $0.3
million. These assets are depreciated using the same useful lives as noted above and included in depreciation expense. See Note 12 –
Notes Payable for minimum future payments related to these equipment leases.

Intellectual Property

On April  13,  2017,  the  Company  entered  into  an  agreement  to  purchase  all  the  capital  shares  of  Ebonex  IPR  Limited,  a  company
registered in England and Wales. Ebonex IPR Limited is a pre-revenue IP-based company that has developed patented technology in
the  field  of  advanced  materials  and  manufacturing  methods  for  advanced  lead  acid  batteries.  Total  consideration  was  $2.5  million,
consisting of cash, transaction costs and 123,776 shares of the Company’s common stock, which at the time had a closing market price
of $17.36 per share. In accordance with ASC Topic 805-50, “Business Combinations – Related Issues”, the Company accounted for
the transaction as an asset acquisition and allocated the consideration to the relative fair value of the assets acquired. The Company
determined  that  the  transaction  was  an  asset  acquisition  rather  than  a  business  combination  following  the  guidance  in  the  above-
mentioned  standard.  In  order  to  be  treated  as  a  business  combination,  the  acquired  assets  and  assumed  liabilities  must  constitute  a
business. A business requires a set of inputs and processes applied to those inputs that have the ability to contribute to the creation of
outputs. Ebonex IPR Limited has no processes such as strategic management processes, operational processes, or employees. Further,
Ebonex  IPR  Limited  provides  no  goods  or  services  to  customers,  nor  has  it  any  investment  or  other  revenues.  Therefore,  the
Company concluded that the acquired assets and assumed liabilities do not constitute a business and are instead treated as an asset
acquisition. Assets acquired consisted of a patent portfolio. The fair value of the patent portfolio, of $112,000,

was determined by management with the assistance of an independent valuation specialist using an income approach. Included in the
purchase were certain fixed assets that have been determined by management to have no immediate value and were not considered in
the valuation of Ebonex IPR.

The  Company  initially  recorded  the  transaction  as  an  increase  of $2.5  million  to  intellectual  property,  net  on  the  balance  sheet.
Subsequently, due to the fair value of the patent portfolio being significantly less than total consideration, the early development stage
of the technology acquired and the uncertainties inherent in research and development, the Company recorded a non-cash impairment
charge of $2.4 million during the three-month period ended June 30, 2017.

The remaining $0.1 million is being amortized straight-line over a 10-year period.

The increase of $0.6 million (including the Ebonex transaction detailed above) and  $0.2 million in 2017 and 2016, respectively, was
due  to  fees  associated  with  additional  patent  and  trademark  filings.  There  were  no  increases  to  intellectual  property  in  2018. The
intellectual property balance is being amortized straight-line over a 10-year period.

current assets in the consolidated balance sheet.

(2) The $1.0 million certificate of deposit is held by Green Bank as collateral for the Green Bank note payable balance. The deposit

with Green Bank will be released after TRIC has three consecutive months of positive cash flow from operations.

(3) The Company has entered into a Facility Closure Trust Agreement for the benefit of the Nevada Division of Conservation and

Natural Resources (NDEP). Funds deposited in the Trust are to be available when and if needed, for closure and/or post-closure
care of the facility related to potential decontamination and hazardous material cleanup. The Trustee will reimburse the
Company or other persons as specified by the NDEP from the fund for closure and post-closure expenditures in such amounts as
the NDEP shall direct in writing. In addition, the Trustee shall refund to the Company such amounts as the NDEP specifies in
writing. $100,000 was deposited upon establishment of the Trust Fund, on October 31, 2016; $350,000 was deposited on
October 31, 2017; and $220,000 was deposited on October 31, 2018.

ASC  Topic  410-20,  “Asset  Retirement  and  Environmental  Obligations, Asset  Retirement  Obligations”  requires  the  recording  of  a
liability in the period in which an asset retirement obligation (ARO) is incurred, in an amount equal to the discounted estimated fair
value of the obligation that is capitalized. In each subsequent fiscal quarter, this liability is accreted up to the final retirement cost. The
determination of the ARO is based on an estimate of the future cost to remove and decontaminate the Company’s facility at TRIC
upon  closure.  The  estimated  fair  value  of  the  closure  costs  is  based  on  vendor  quotes  to  remove  and  decontaminate  the  McCarran
facility  in  accordance  with  the  Company’s  closure  plan  as  filed  with  the  State  of  Nevada  in  its  “Application  for  the  Recycling  of
Hazardous  Waste,  by  Written  Determination”  in  2016.  The  actual  costs  could  be  higher  or  lower  than  current  estimates.  The
discounted estimated fair value of the closure costs was $0.7 million and the obligation was recorded as of March 31, 2017, when the
obligation  was  deemed  to  have  occurred.  Offsetting  this ARO  is,  as  noted  in  Note  5  above,  an  asset  retirement  cost  of  the  same
amount  that  was  capitalized. Accretion  of  the ARO  for  the  year  ended  December  31,  2018  and  2017  was  $44,000  and $31,000
respectively.

The Company entered into a facility closure trust agreement in October 2017 for the benefit of the Nevada Division of Environmental
Protection (NDEP), an agency of the Nevada Division of Conservation and Natural Resources. Funds deposited in the trust are to be
available,  when  and  if  needed,  for  potential  decontamination  and  hazardous  material  cleanup  in  connection  with  the  closure  and/or
post-closure care of the facility. The trustee will reimburse the Company or other persons as specified by the NDEP from the fund for
closure and post-closure expenditures in such amounts as the NDEP shall direct in writing. Through December 31, 2018, $670,000 has
been contributed to the trust fund.

10. Convertible Notes

As described more completely under the caption “Interstate Battery Agreements” below in Note 13, the Company issued to Interstate
Battery System International, Inc. and its wholly-owned subsidiary (collectively “Interstate Battery”) a convertible note with a face
amount of $5.0 million and interest of 11% per annum due May 25, 2019. The note is convertible at  $7.12 per share of common stock.
The  Company  allocated  the  proceeds  from  the  Interstate  Battery  agreements  to  the  convertible  note,  common  stock  and  warrants
comprising the financing agreements based on the relative fair value of the individual securities on the May 24, 2016 closing date of
the agreements. Additionally, the convertible notes contained an embedded conversion feature having intrinsic value at the issuance
date,  which  value  the  Company  treated  as  an  additional  discount  attributed  to  the  convertible  note,  subject  to  limitations  on  the
absolute  amount  of  discount  attributable  to  the  convertible  notes  and  its  allocated  value.  The  Company  recorded  a  corresponding
credit  to  additional  paid-in  capital  attributable  to  the  beneficial  conversion  feature  (“BCF”).  The  discounts  attributable  to  the
convertible note, an aggregate of $4,975,000, are being amortized using the effective interest method over the  three-year term of the
note, maturing on May 24, 2019. Because the discount on the convertible note exceeds 99% of its initial face value, and because the
discount is amortized over the period from issuance to maturity, the calculated effective interest rate is 184.75% per annum.

Interest cost on the note for the years ended December 31, 2018, 2017 and 2016 totaled $0.7 million, $0.6  million  and $0.3 million,
respectively. Amortization  of  the  note  discount  for  the  years  ended  December  31,  2018,  2017  and  2016  totaled  $2.0  million, $0.4
million and $0.1 million, respectively. Amortization of the deferred financing costs, more fully described in Note 13, totaled  $47,000,
$48,000 and $27,000 for the years ended December 31, 2018, 2017 and 2016, respectively.

As of December 31, 2018, the Interstate Battery convertible note’s “if-converted value” did not exceed its principal amount. As further
described in Note 19 - Subsequent Events. This note was fully paid off in January 2019.

11. Deferred Rent

On August 7, 2015, the Company signed a lease for 21,697 square feet of mixed office and manufacturing space in Alameda, CA. The
term of the lease is 76 months plus 6 months pre-commencement date for tenant improvement construction. The total cost of the lease
is $3.0 million  which  was  being  amortized  over 82  months  at  approximately $37,000  per  month. As  of  December  31,  2016,  the
landlord  had  paid  for $0.9 million  in  tenant  improvements.  The  tenant  improvements  cost  has  been  included  in  owned  assets  and
deferred rent and was being amortized over the life of the lease.

In  July  2018,  the  Company  signed  a  lease  for 14,016  square  feet  of  mixed  office  and  warehouse  space  in  McCarran,  Nevada. The
lease term is 42 months. The total cost of the lease is $0.4 million, which is being amortized over 42 months at approximately $9,000
per month.

Amortization  of  deferred  rent  expense  for  the  years  ended  December  31,  2018  and  2017  was  $0.1  million  and $0.2  million,
respectively. Net deferred rent expense for the year ended December 31, 2016 was $29,000.

In  October  2018,  the  Company  moved  its  corporate  headquarters  to  its  McCarran,  Nevada  facility  and  ceased  to  use  its Alameda,
California facility. In February 2019, the Company sublet the California facility. Upon vacating the property, the Company wrote

lease  payments  less  estimated  sublease  income  in  the  amount  of $0.3  million  recorded  in  the  balance  sheet  as  lease  liability.
Additionally,  the  Company  wrote  off  the  net  book  value  of  its  leasehold  improvements  of  approximately  $0.8  million  during  the
fourth quarter of 2018.

12. Notes Payable

AMR entered into a $10,000,000 loan with Green Bank on November 3, 2015. The term of the loan is twenty-one years. For the first
twelve months only interest was payable; thereafter monthly payments of interest and principal are due. The interest rate adjusts on the
first day of each calendar quarter equal to the greater of six percent (6%) or two percent (2%) per annum above the minimum prime
lending rate charged by large U.S. money center commercial banks as published in the Wall Street Journal. The terms of the Loan
Agreement contain various affirmative and negative covenants. Among them, AMR must maintain a minimum debt service coverage
ratio of 1.25 to 1.0 (beginning with the twelve-month period ending March 31, 2017), a maximum debt-to-net worth ratio of  1.0 to 1.0
and a minimum current ratio of 1.5 to 1.0. AMR was in compliance with all covenants as of and for the years ending December 31,
2016  and  2015. AMR  was  in  compliance  with  all  but  the  minimum  debt  service  coverage  ratio  covenant  as  of  and  for  each  of  the
calendar  quarters  in  the  period  March  31,  2017  through  December  31,  2018. AMR  has  received  a  waiver  for  the  minimum  debt
service coverage ratio covenant for each period of non-compliance.

Collateral for this loan is AMR’s accounts receivable, goods, equipment, fixtures, inventory, accessions and a certificate of deposit in
the amount of $1.0 million.

The loan is guaranteed by the United States Department of Agriculture Rural Development (“USDA”), in the amount of  90% of the
principal amount of the loan. The Company paid a guarantee fee to the USDA in the amount of  $270,000 at the time of closing and
will  be  required  to  pay  to  the  USDA  an  annual  fee  in  the  amount  of 0.50%  of  the  guaranteed  portion  of  the  outstanding  principal
balance of the loan as of December 31 of each year.

Notes payable is comprised of the following (in thousands):

The capital equipment lease obligations relate to capital leases further discussed in Note 5 – Property and Equipment, net. The costs
associated with obtaining the Green Bank loan of $0.8 million were recorded as a reduction to the carrying amount of the note and are
being  amortized  as  interest  expense  over  the  twenty-one  year  life  of  the  loan. Amortization  of  the  deferred  financing  costs  was
$35,000, $35,000 and $35,000 for the years ended December 31, 2018, 2017 and 2016, respectively. The principal payments detailed

Interstate Battery Agreements

Investment Agreement

The Company entered into a Credit Agreement dated May 18, 2016 with Interstate Battery pursuant to which Interstate Battery loaned
the  Company $5.0  million  in  consideration  of  the  Company’s  issuance  of  a  secured  convertible  promissory  note  in  the  original
principal amount of $5.0 million. The note bears interest at the rate of eleven percent (11%) per annum, compounding monthly, and
all  interest  is  payable  upon  the  earlier  of  maturity  or  conversion  of  the  principal  amount.  The  loan  matures  on May 24, 2019.  The
outstanding  principal  is  convertible  into  shares  of  the  Company’s  common  stock  at  a  conversion  price  of  $7.12  per  share.  The
Company’s  obligations  under  the  note  and  Credit Agreement  are  secured  by  a  second  priority  lien  on  the  real  estate,  fixtures  and
equipment at the Company’s recycling facility at McCarran, Nevada. The Credit Agreement includes representations, warranties, and
affirmative  and  negative  covenants  that  are  customary  of  institutional  credit  agreements.  Interstate  Battery  had  previously  raised  a
claim  that  the  Company  was  in  technical  breach  of  a  negative  covenant  under  loan.  The  claimed  breach  related  to  the  Company’s
failure to obtain Interstate Battery’s prior written consent to the Company’s acquisition of Ebonex IPR, Ltd. The Company estimated
in  2017  that  resolving  the  claim  would  result  in  a  charge  of $0.6 million.  The  Company  recorded  the $0.6 million  in  general  and
administrative expenses as of December 31, 2017 with the offset in accrued liabilities. The Company resolved this alleged breach in
connection with a series of agreements with Interstate Battery in June 2018 as further described below and in Note 14.

Pursuant to the Credit Agreement, the Company also issued to Interstate Battery two common stock purchase warrants, including:

•

•

a  warrant  to  purchase 702,247  shares  of  the  Company’s  common  stock,  at  an  exercise  price  of $7.12  per  share,  that  is
exercisable upon grant and expires on May 24, 2018; and

a  warrant  to  purchase 1,605,131  shares  of  the  Company’s  common  stock,  at  an  exercise  price  of $9.00  per  share,  that  is
exercisable commencing November 24, 2016 and expires on May 24, 2019.

The warrants contain cashless exercise and standard anti-dilution adjustment provisions. The first warrant issued above was modified
in June 2018 to extend the expiration date to June 30, 2020 and reduce the exercise price to $3.33 peer share. See Note 14 for further
details  of  this  modification. If  Interstate  converts  its  convertible  note  and  exercises  both  warrants  in  their  entirety,  it  will  own
approximately 8.3% of the Company’s common stock at an average price per share of approximately $7.22.

53

 
 
 
 
 
 
 
The  Company  also  entered  into  a  Stock  Purchase Agreement  dated  May  18,  2016  with  Interstate  Battery  pursuant  to  which  the
Company issued and sold to Interstate Battery 702,247 shares of the Company’s common stock at  $7.12 per share for gross proceeds
of  approximately $5.0  million.  The  Stock  Purchase Agreement  includes  customary  representations,  warranties,  and  covenants  by
Interstate Battery and us, and an indemnity from us in favor of Interstate Battery.

In connection with the investment transactions, the Company also entered into an Investors Rights Agreement dated May 18, 2016
with Interstate Battery pursuant to which the Company granted Interstate Battery customary demand and piggyback registration rights,
limited  board  observation  rights  over  the  next three  years  and  limited  preemptive  rights  allowing  Interstate  Battery  the  right  to
purchase its proportional share of certain future equity issuances by the Company over the next three years. The Company included all
of  the  Interstate  Battery  shares  in  its  S-3  Registration  Statement  filed  with  the  Securities  and  Exchange  Commission  on August  1,
2016.

The investment transactions with Interstate Battery closed on May 24, 2016. There were no sales commissions paid by the Company
in connection with its sale of securities to Interstate Battery.

The  Company  allocated  the $10.0  million  proceeds  from  the  Credit  Agreement  and  Stock  Purchase  Agreement,  to  the  various
securities based on their relative fair values on the closing date of May 24, 2016.

•

•

The fair value of the note was calculated using an average of the Merrill Lynch US High Yield CCC rate of  16.21%  on
May 24, 2016 and the Merrill Lynch US High Yield B effective yield of 7.44% on May 24, 2016.

The  fair  value  of  the  common  stock  was  based  on  the  closing  market  price  of  the  Company’s  common  stock  on  the
NASDAQ stock market on May 24, 2016.

The fair value of the warrants using the Black-Scholes-Merton option pricing model and the assumptions are listed in the table below

The difference between the face value of the convertible note and the allocated amount (which considers both the allocated fair value
of the issued stock and allocated fair value of the warrants) was recorded as an initial discount to the convertible note; common stock
was recorded at its allocated fair value as a credit to par value and additional paid-in capital as appropriate, based

on the number of shares issued, and the allocated fair value of the warrant was credited to additional paid-in capital. After taking into
consideration the amortization of the note discount, the effective interest rate on the convertible note is 184.75% per annum.

The  convertible  note  includes  an  embedded  BCF.  The  intrinsic  value  of  the  BCF  was  treated  as  an  additional  component  of  the
discount  attributable  to  the  convertible  note.  The  initial  discount  (attributable  to  the  stock  and  warrants  as  noted  above)  and  the
discount attributable to the BCF exceeds the face amount of the convertible note. To avoid reducing the initial net carrying value of
the convertible note to or below zero, the discount attributable to the BCF was limited such that the aggregate of all discounts does
not  exceed 99.5% of the face amount of the convertible note. The discount is being accreted to interest expense using the effective
interest  method  over  the  three-year  life  of  the  loan.  If  the  loan  is  converted  prior  to  its  maturity,  any  remaining  discount  will  be
expensed immediately.

Costs incurred in connection with the deal of $771,000 were allocated between additional paid-in capital and prepaid financing/ debt
discount  (“debt  issuance  costs”)  in  the  same  manner  as  the  above  allocation  of  proceeds.  The  allocated  debt  issuance  costs  of
$142,000 were recorded as a reduction to the carrying amount of the convertible note and are being amortized as interest expense over
the three-year life of the loan. The remaining $629,000 was recorded as a reduction to additional paid-in capital.

National Securities Placement

On  May  18,  2016,  the  Company  entered  into  a  Stock  Purchase  Agreement  and  a  Registration  Rights  Agreement  with  certain
accredited investors pursuant to which the Company issued and sold to the investors 719,333 shares of its common stock at a price of
$7.12  per  share  for  the  gross  proceeds  of  approximately $5.1  million.  The  Stock  Purchase  Agreement  includes  customary
representations,  warranties,  and  covenants  by  the  investors  and  the  Company,  and  an  indemnity  from  the  Company  in  favor  of  the
investors. The private placement closed on May 24, 2016. The Company included all of these shares in its S-3 Registration Statement
filed with the Securities and Exchange Commission on August 1, 2016.

National Securities Corporation acted as placement agent for the private placement and received sales commission in the amount of six
percent (6%) of the gross proceeds, or a total of $307,000 in commissions from us. In addition, we reimbursed National Securities for
its  out-of-pocket  expenses  and  legal  fees  in  the  aggregate  amount  of $38,000.  The  total  costs  of $345,000  have  been  recorded  as  a
reduction to additional paid-in capital.

2016 Public Offering

On November 21, 2016, the Company completed a public offering of  2.3 million shares of its common stock at a public offering price
o f $10.00  per  share.  Net  proceeds  to  the  Company  from  the  public  offering  were  approximately $21.5  million  after  deducting
underwriting discounts, commissions and offering expenses. In connection with the public offering, the underwriter received a fee of
$1.4  million  and  a  warrant  to  purchase 33,450  shares  of  the  Company’s  common  stock  at  $10.00  per  share  that  is  exercisable
commencing May 20, 2017 and expires on November 21, 2019. The fair value of the warrant,  $229,000, was recorded as an increase
to  offering  expenses  and  an  increase  to  additional  paid-in  capital.  The  Company  calculated  the  fair  value  of  the  warrant  using  a
BlackScholes  Merton  model  with  the  assumptions  as  follows: $12.66  closing  market  value  on  the  date  of  grant; 3-year  term; 72%
volatility; 1.36% discount rate and 0% annual dividend rate.

Johnson Controls Agreement

On February 7, 2017, the Company entered into a Stock Purchase Agreement with Johnson Controls pursuant to which the Company
issued  and  sold  to  a  wholly-owned  subsidiary  of  Johnson  Controls  International  plc,  (“Johnson  Controls”), 939,005  shares  of  its
common  stock  at $11.33  per  share  for  the  gross  proceeds  of  approximately $10.6  million.  Costs  incurred  in  connection  with  the
transaction, primarily legal fees, totaled approximately $167,000. The Stock Purchase Agreement includes customary representations,
warranties, and covenants by Johnson Controls and the Company, and an indemnity from the Company in favor of Johnson Controls.

In connection with the investment transactions, the Company also entered into an Investors Rights Agreement dated February 7, 2017
with Johnson Controls pursuant to which the Company granted Johnson Controls customary demand and piggyback registration rights,
limited board observation rights and limited preemptive rights allowing Johnson Controls the right to purchase its proportional share of
certain future equity issuances by the Company. The board observation and preemptive rights shall expire on the earlier of (i) such
time  as  Johnson  Controls  no  longer  owns 50%  of  the  acquired  shares  or  (ii)  the  termination  of  both  the  Tolling/Lead  Purchase
Agreement and Equipment Supply Agreement.  

There were no sales commissions paid by the Company in connection with the sale of its common shares to Johnson Controls.

Warrant modification

On June 24, 2018, the Company entered into a series of agreements (see Note 14 for details) with Interstate Battery, which modified
the terms of a warrant to purchase 702,247 shares of our common stock by reducing the exercise price of the warrant from $7.12 per
share to $3.33 per share and extended the expiration date of the warrant from June 24, 2018 to June 23, 2020. The expiration date had
previously been extended from May 2018 to June 2018 as part of the overall negotiations. The incremental fair value resulting from
this  modification  was  calculated  to  be $1.0 million using the Black-Scholes-Merton  Option  Pricing  Model  with  the  assumptions  as
follows: $3.26  per  share  fair  value  on  the  date  of  modification; 2-year  term; 80.2%  volatility; 2.56%  discount  rate  and 0%  annual
dividend rate.

The Company previously recorded  $0.6 million in general and administrative expense during the year ended December 31, 2017 with
the offset in accrued liabilities as an estimate of this liability.  Upon modification, the Company recorded an additional $0.4 million in
general and administrative expense for the three months ended June 30, 2018, relieved $0.6 million in accrued liabilities with the $1.0
million offset to additional paid-in capital.

Stock-based compensation

In  2014,  the  Board  of  Directors  adopted  the  Company’s  stock  incentive  plan  (the  “2014  Plan”).  The  2014  Plan  was  most  recently
amended  and  restated  effective  as  of  the  Company’s  2017 Annual  Stockholders’  Meeting. A  total  of  2,113,637  shares  of  common
stock was authorized for issuance pursuant to the 2014 Plan at the time of its most recent amendment and restatement in 2017.

The 2014 Plan provides for the following types of stock-based awards: incentive stock options; non-statutory stock options; restricted
stock;  and  performance  stock.  The  2014  Plan,  under  which  equity  incentives  may  be  granted  to  employees  and  directors  under
incentive and non-statutory agreements, requires that the option price may not be less than the fair value of the stock at the date the
option is granted. Option awards are exercisable until their expiration, which may not exceed 10 years from the grant date.

The risk-free interest rate assumption was based on the United States Treasury’s zero-coupon bonds with maturities similar to those of
the  expected  term  of  the  award  being  valued.  The  assumed  dividend  yield  was  based  on  the  Company’s  expectation  of  not  paying
dividends in the foreseeable future. The weighted-average expected life of the options was calculated using the simplified method as
prescribed by the Securities and Exchange Commission (“SEC”) Staff Accounting Bulletin No. 107 and No. 110 (“SAB No. 107 and
110”). This decision was based on the lack of relevant historical data due to the Company’s limited historical experience. In addition,
due to the Company’s limited historical data, the estimated volatility also reflects the application of SAB No. 107 and 110, using the
weighted average of the Company’s historical volatility and the historical volatility of several unrelated public companies within the
recycling industry. Forfeitures are recognized as they occur.

The number of options granted during 2018 include 840,000 options subject to the terms and conditions of the Company’s Amended
and Restated 2014 Stock Incentive Plan (“2014 Plan) but were not issued under the 2014 Plan in reliance on Nasdaq Rule 5635(c)(4)
and therefore do not reduce the number of shares available under the 2014 Plan.

The weighted-average grant-date fair value of options granted during the year ended December 31, 2018, 2017 and 2016 was  $1.71,
$5.55 and $4.47 per share, respectively. The intrinsic value of options exercised during the year ended December 31, 2017 and 2016
was $1.5  million  and $22,000,  respectively.  There  were  no  stock  option  exercises  during  the  year  ended  December  31,  2018.  The
amount of cash received from exercise of stock options during the year ended December 31, 2017 was $1.1 million.

In connection with his appointment as President of the Company in May 2018, Stephen Cotton was awarded options to purchase up to
840,000 shares of the Company’s common stock. Options to purchase 420,000 common shares are exercisable over a five-year period
at  an  exercise  price  of $3.00  per  share. Options  to  purchase 210,000  common  shares  are  exercisable  over  a five-year  period  at  an
exercise price of $5.00 per share and options to purchase 210,000 common shares are exercisable over a five-year period at an exercise
price of $7.00 per share. The options vest in 1/36th increments during each of the first twelve months following the date of grant and
thereafter  the  options  vest  in  one-third  increments  on  the  second  and  third  anniversary  of  the  date  of  grant. The  options  issued  are
subject to the terms and conditions of the 2014 Plan but were not issued under the 2014 Plan in reliance on with Nasdaq Rule 5635(c)
(4) and therefore do not reduce the number of shares available under the 2014 Plan.

In connection with his termination, the stock options of the Company’s former CEO were modified to extend the exercise period upon
termination from 90 days to 2 years. The expense related to the modification of these stock option awards was approximately $15,000
and was recorded during the second quarter of 2018.

During the three months ended June 30, 2016, the Compensation Committee of the Board of Directors approved the modification of
the terms of a stock option previously granted to a member of its Board of Directors to accelerate vesting and the waiver of the early
termination  of  the  option  based  upon  the  director’s  end  of  service  to  the  Company.  The  modification  resulted  in  additional
compensation expense of $175,000.

Restricted Stock Units

In April 2018, the Company granted 150,000 restricted stock units (RSUs), all of which were subject to vesting, with a grant fair value
of $339,000 to its then-Chief Financial Officer, Francis Knuettel II, as part of his employment agreement. Mr. Knuettel resigned in
August 2018 and all of the RSUs expired by their terms prior to vesting.

In  July  2017,  the  Company  granted 49,751 restricted stock units (RSUs) with a grant date fair value per share of $11.68 to its then
Chief Financial Officer, Mr. Weinswig, as part of his employment agreement. Mr. Weinswig resigned in March 2018 and all of the
RSUs expired by their terms prior to vesting.

Total intrinsic value of RSUs vested and released during 2018 was $0.1 million. Intrinsic value of RSUs outstanding at December 31,
2018 was $0.2 million.

As of December 31, 2018, there is approximately $11,000 of total unrecognized compensation cost related to the unvested share-based
(RSU) compensation arrangements granted under the 2014 Plan. The remaining unrecognized compensation cost will be recognized
over a weighted-average period of 11 days.

benefits  continuation  expense  of  approximately $0.9 million  paid  out  over  a 2-year  period  in  consideration  of  his  execution  of  a
customary release and separation agreement. Additionally, as noted above, Dr. Clarke was granted an extension of the exercise period
of his stock options upon termination from 90 days to 2 years. The expense related to the modification of these stock option awards
was approximately $15,000.

On  December  3,  2018,  Sewlyn  Mould  resigned  as  chief  operating  officer.  Mr.  Mould’s  resignation  as  an  officer  the  Company  was
treated as a termination without cause under his employment agreement with the Company. Pursuant to his employment agreement,
Mr.  Mould  was  entitled  to  one-time  severance  benefits  that  includes  severance  and  benefits  continuation  expense  of  approximately
$0.9 million paid out over a 2-year period in consideration of his execution of a customary release and separation agreement. Pursuant
to a Separation Agreement and Release between the Company and Mr. Mould, Mr. Mould has agreed to receive, in lieu

60

 
 
 
 
 
 
of  two  years  of  salary,  a  cash  severance  payment  of $100,000  payable  in  six  equal  installments  in  accordance  with  the  Company's
regular payroll practices, plus an award of restricted stock units that will entitle him to receive, for each of the 21 consecutive months
commencing  on  March  1,  2019, $33,333  of  the  Company's  common  shares  based  on  volume-weighted  average  price  over  the 20
trading days preceding the first business day of the respective month. The Company has reserved the right, at its option, to pay Mr.
Mould $33,333 of cash in lieu of any of the 21 monthly share issuances. The Separation Agreement and Release includes customary
indemnification, confidentiality, non-disparagement and non-solicitation covenants and agreements of the parties.

Interstate Battery Agreement commitment

Pursuant to the 2016 Interstate Battery Investor Rights Agreement, the Company had agreed to compensate Interstate Battery should
either  Stephen  Clarke,  the  Company’s  former  chief  executive  officer,  or  Selwyn  Mould,  the  Company’s  current  chief  operating
officer,  no  longer  hold  such  positions  or  no  longer  devote  substantially  all  of  their  business  time  and  attention  to  the  Company,
whether as a result of resignation, death, disability or otherwise (such an event referred to as a “key-man event”). The Company had
agreed  to  pay  Interstate  Battery $2.0 million,  per  occurrence,  if  either  officer  was  subject  to  a  key-man  event  during  the  two  years
following May 18, 2016. The Company also agreed to pay Interstate Battery $2.0 million if either or both officers were subject to a
key-man event during the third year following May 18, 2016. Pursuant to the Interstate Battery Investor Rights Agreement, the key-
man  payments  are  payable,  at  the  option  of  the  Company,  in  cash  or  shares  of  the  Company’s  common  stock.  Pursuant  to  the
agreement, if Interstate Battery, in its sole and absolute discretion, agrees with the Company on mutually acceptable replacements. for
Messrs. Clarke and/or Mould, as the case may be, the key man penalties shall be deemed waived by Interstate Battery.

Interstate  Battery  had  previously  raised  a  claim  that  the  Company  was  in  technical  breach  of  a  negative  covenant  under  the  Credit
Agreement dated May 18, 2016 between the Company and Interstate Battery. The claimed breach related to the Company’s failure to
obtain Interstate Battery’s prior written consent to its acquisition of Ebonex IPR, Ltd.

On June 24, 2018, the Company entered into a series of agreements with Interstate Battery, including an amendment to the Investor
Rights  Agreement.  Pursuant  to  the  amendment  to  the  Investor  Rights Agreement,  Interstate  Battery  agreed  to  waive  all  payments
under  the  key-man  provisions  of  the  Investor  Rights  Agreement  with  respect  to  the  resignation  of  the  Company’s  former  chief
executive officer, Stephen Clarke. In addition, the parties agreed that the Company, at its option, can elect to eliminate the key-man
event  and  all  related  key-man  payments  associated  with  Mr.  Mould  by  (i)  paying  Interstate  Battery  a  one-time  fee  of $0.5  million,
payable  in  cash  and  (ii)  agreeing  to  pay  Interstate  Battery $2.0 million,  payable  at  the  Company’s  election  in  cash  or  shares  of  its
common  stock,  should  the  Company’s  current  president,  Stephen  Cotton  no  longer  serve  as  president  of  the  Company  during  the
period ending May 18, 2019. On December 3, 2018, Mr. Mould resigned as chief operating officer. The Company agreed to to pay the
one time fee of $0.5 million. Additionally:

61

 
 
 
 
• With  respect  to  a  Credit Agreement  dated  May  18,  2016  between  the  Company  and  Interstate  Battery,  Interstate  Battery

waived the alleged breach of the Credit Agreement based on the Company’s acquisition of Ebonex IPR, Ltd.;

• The Company adjusted the terms of a warrant to purchase  702,247 shares of its common stock issued to Interstate Battery in
May 2016, pursuant to which the exercise price of the warrant was decreased from $7.12 per share to $3.33 per share and the
expiration date of the warrant was extended to June 23, 2020; and

• Interstate  Battery  agreed  to  provide  the  Company  with  more  favorable  pricing  and  payment  terms  under  the  Supply

Agreement dated May 18, 2016 pursuant to which the Company buys used lead acid batteries from Interstate Battery.

Johnson Controls Agreement Commitment

Pursuant to the Johnson Controls Investor Rights Agreement, the Company has agreed to compensate Johnson Controls should either
Stephen Clarke, the Company’s current chief executive officer, or Selwyn Mould, the Company’s current chief operating officer, no
longer  hold  such  positions  or  no  longer  devote  substantially  all  of  their  business  time  and  attention  to  the  Company,  whether  as  a
result of resignation, death, disability or otherwise (such an event referred to as a “key-man event”). The Company has agreed to pay
Johnson Controls $1.0 million per occurrence, if either officer is subject to a key-man event during the 18 months following February
7, 2017. The Company also agreed to pay Johnson Controls $1.0 million if either or both key-man events occur after 18 months and
prior  to  30  months  following  February  7,  2017. Pursuant  to  the  agreement,  if  Johnson  Controls,  in  its  sole  and  absolute  discretion,
agrees with the Company on mutually acceptable replacements. for Dr. Clarke and/or Mr. Mould, as the case may be, the key man
penalties shall be deemed waived by Johnson Controls. In connection with the resignations by Dr. Clarke and Mr. Mould described
above, Johnson Controls has submitted to the Company its claim for payment of the key-man penalties in the total amount of $2.0
million. The Company has accrued the $2.0 million at December 31, 2018 but believes, however, that Johnson Controls’ demand was
premature  as  it  had  not  considered  the  adequacy  of  the  replacements  for  Dr.  Clarke  or  Mr.  Mould  and  that  any  such  claim  can  be
asserted after their replacements have been appointed and considered in good faith.

Legal proceedings

Beginning on December 15, 2017, three purported class action lawsuits were filed in the United Stated District Court for the Northern
District California against the Company, Stephen Clarke, Thomas Murphy and Mark Weinswig.  On March 23, 2018, the cases were
consolidated  under  the  caption  In  Re: Aqua  Metals,  Inc.  Securities  Litigation  Case  No  3:17-cv-7142.  On  May  23,  2018,  the  Court
appointed  lead  plaintiffs  and  approved  counsel  for  the  lead  plaintiffs.    On  July  20,  2018,  the  lead  plaintiffs  filed  a  consolidated
amended complaint (“Amended Complaint”), on behalf of a class of persons who purchased the Company’s securities between May
19,  2016  and  November  9,  2017,  against  the  Company,  Stephen  Clarke,  Thomas  Murphy  and  Selwyn  Mould.    The  Amended
Complaint  alleges  the  defendants  made  false  and  misleading  statements  concerning  the  Company’s  lead  recycling  operations  in
violation of Section 10(b) of the Securities Exchange Act of 1934 (“Exchange Act”) and Rule 10b-5 promulgated thereunder.  The
Amended Complaint seeks to hold the individual defendants as control persons pursuant to Section 20(a) of the Exchange Act.  The
Amended Complaint also alleges a violation of Section 11 of the Securities Act of 1933 (“Securities Act”) based on alleged false and
misleading  statements  concerning  the  Company’s  lead  recycling  operations  contained  in,  or  incorporated  by  reference  in,  the
Company’s Registration Statement on Form S-3 filed in connection with its November 2016 public offering.   That claim is asserted
on behalf of a class of persons who purchased shares pursuant to, or that are traceable to, that Registration Statement.  The Amended
Complaint  seeks  to  hold  the  individual  defendants  liable  as  control  persons  pursuant  to  Section  15  of  the  Securities  Act.    The
Amended Complaint seeks unspecified damages and plaintiffs’ attorneys’ fees and costs.  On September 18, 2018, the defendants filed
a motion to dismiss the Amended Complaint in its entirety and the plaintiff subsequently filed its opposition to the motion.  In January
2019, the court notified the parties that it will rule on the motion to dismiss without a hearing. The Company denies that the claims in
the Amended Complaint have any merit and it intends to vigorously defend the action.

Beginning  on  February  2,  2018,  five  purported  shareholder  derivative  actions  were  filed  in  the  United  States  District  Court  for  the
District of Delaware against the Company and certain of its current and former executive officers and directors, Stephen R. Clarke,
Selwyn  Mould,  Thomas  Murphy,  Mark  Weinswig,  Vincent  DiVito,  Mark  Slade  and  Mark  Stevenson.    On  May  3,  2018,  the  cases
were consolidated under the caption In re Aqua Metals, Inc. Stockholder Derivative Litigation, Case No. 1:18-cv-201-LPS (D. Del.).
The complaints were filed by persons claiming to be stockholders of Aqua Metals and generally allege that certain of the Company’s
officers  and  directors  breached  their  fiduciary  duties  to  the  Company  by  violating  the  federal  securities  laws  and  exposing  the
Company  to  possible  financial  liability.    The  complaints  seek  unspecified  damages  and  plaintiffs’  attorneys’  fees  and  costs.    The
parties  have  entered  into  a  stipulation  staying  the  action  until  30  days  after  a  decision  on  the  Company’s  motion  to  dismiss  the
Amended Complaint in the class action described above.  The individual defendants deny that the claims in the shareholder derivative
action have any merit and it intends to vigorously defend the action.

The Company is not party to any other legal proceedings.  The Company may, from time to time, be party to litigation and subject to
claims incident to the ordinary course of business.  As its growth continues, the Company may become party to an increasing number
of litigation matters and claims.  The outcome of litigation and claims cannot be predicted with certainty, and the resolution of any
future matters could materially affect its future financial position, results of operations or cash flows.

The Company’s effective tax rate for the period ended December 31, 2018 was lower than the statutory tax rate primarily because of
the valuation allowance on its US deferred tax assets taxed at lower rates, partially offset by state taxes and tax credits. The income
tax expense for the year ended December 31, 2018, 2017 and 2016 relate to state minimum income tax.

On December 22, 2017, President Trump signed the Tax Cuts and Jobs Act (the “Act”) into law. The new legislation decreases the
U.S.  corporate  federal  income  tax  rate  from 35%  to 21%  effective  January  1,  2018.  There  was  no  impact  on  recorded  deferred  tax
balances  as  the  remeasurement  of  net  deferred  tax  assets  was  offset  by  a  change  in  valuation  allowance.  The Act  also  includes  a
number  of  other  provisions  including  the  elimination  of  loss  carrybacks  and  limitations  on  the  use  of  future  losses,  repeal  of  the
Alternative Minimum Tax regime, and the introduction of a base erosion and anti-abuse tax. These provisions are not expected to have
immediate effects on the Company.

Based on the available objective evidence at this time, management believes that it is more likely than not that the net deferred tax
assets of the Company will not be fully realized. Accordingly, management has applied a full valuation allowance against net deferred
tax assets at both December 31, 2018 and December 31, 2017. The net valuation allowance increased by approximately $7.9 million
during the year ended December 31, 2018. The increase in net valuation allowance primarily relates to net operating losses generated
during 2018 partially offset by a decrease related to the lower U.S. corporate federal income tax rate effective January 1, 2018.

The  Company  has  Federal  and  California  net  operating  loss  carry-forwards  of  approximately  $61.3  million  and $3.8  million,
respectively, available to reduce future taxable income which will begin to expire in December 31, 2034 for Federal and California
purposes.

At  December  31,  2018,  the  Company  had  research  and  development  credits  carryforward  of  approximately $0.3 million  and $0.5
million  for  Federal  and  California  income  tax  purposes,  respectively.  If  not  utilized,  the  Federal  research  and  development  credits
carryforward will begin to expire in December 31, 2034. The California credits can be carried forward indefinitely.

Utilization  of  the  Company’s  net  operating  loss  may  be  subject  to  substantial  annual  limitation  due  to  the  ownership  change
limitations  provided  by  the  Internal  Revenue  Code  and  similar  state  provisions.  Such  an  annual  limitation  could  result  in  the
expiration of net operating loss carryforwards prior to utilization.

The Company’s policy is to account for interest and penalties as income tax expense. As of December 31, 2018, the Company had no
interest  related  to  unrecognized  tax  benefits.  No  amounts  of  penalties  related  to  unrecognized  tax  benefits  were  recognized  in  the
provision for income taxes.

The Company maintains liabilities for uncertain tax positions. These liabilities involve considerable judgement and estimation and are
continuously monitored by management based on the best information available, including changes in tax regulations, the

outcome of relevant court cases, and other information. The Company recognizes potential accrued interest and penalties related to
unrecognized  tax  benefits  as  income  tax  expense. At  December  31,  2018,  the  Company’s  total  amount  of  unrecognized  tax  benefit
was  approximately $0.2 million,  none  of  which  will  affect  the  effective  tax  rate,  if  recognized.  The  Company  does  not  expect  its
unrecognized benefits to change materially over the next twelve months.

The  Company  files  income  tax  returns  with  the  United  States  federal  government  and  the  State  of  California.  The  Company’s  tax
returns for all prior years from the Company's inception in 2014 remain open to audit for Federal and California purposes.

Prior to January 1, 2017, the Company recognized the excess tax benefits of stock-based compensation expense as additional paid-in
capital (“APIC”), and tax deficiencies of stock-based compensation expense in the income tax provision or as APIC to the extent that
there were sufficient recognized excess tax benefits previously recognized. As a result of the prior requirement that excess tax benefits
reduce  taxes  payable  prior  to  be  recognized  as  an  increase  in  paid  in  capital,  the  Company  had  not  recognized  certain  deferred  tax
assets (all tax attributes such as loss or credit carryforwards) that could be attributed to tax deductions related to equity compensation
in excess of compensation recognized for financial reporting.

Effective as of January 1, 2017, the Company adopted a change in accounting policy in accordance with ASU 2016-9 to account for
excess tax benefits and tax deficiencies as income tax expense or benefit, and to recognize previously unrecognized deferred tax assets
that  arose  directly  from  (or  the  use  of  which  was  postponed  by)  tax  deductions  related  to  equity  compensation  in  excess  of
compensation  recognized  for  financial  reporting.  The  change  was  applied  on  a  modified  retrospective  basis;  no  prior  periods  were
restated as a result of this change in accounting policy.

ASU  2016-9  also  eliminates  the  requirement  that  excess  tax  benefits  be  realized  as  a  reduction  in  current  taxes  payable  before  the
associated  tax  benefit  can  be  recognized  as  an  increase  in  paid  in  capital. Approximately $0.2 million  of  capitalized  start-up  costs
(none of which were included in the deferred tax assets recognized in the statement of financial position as of December 31, 2016)
have been attributed to tax deduction for stock-based compensation in excess of the related book expense. Under ASU 2016-9, these
previously unrecognized deferred tax assets were recognized on a modified retrospective basis as of January 1, 2017, the start of the
year in which the Company adopted ASU 2016-9. The capitalized start-up costs recognized as of January 1, 2017, as described above,
have  been  offset  by  a  valuation  allowance. As  a  result,  there  was  no  tax-related  cumulative-effect  to  retained  earnings  for  US  tax
purpose.

The Company made the election to early adopt ASU 2015-17 at December 31, 2016 to classify all deferred tax assets and liabilities,
along with any related valuation allowance, as noncurrent on the balance sheet.

17.

401(k) Savings Plan
The Company maintains a defined-contribution savings plan under Section 401(k) of the Internal Revenue Code (the “401(k) Plan”).
The  401(k)  Plan  covers  all  employees  who  meet  defined  minimum  age  and  service  requirements  and  allows  participants  to  defer  a
portion of their annual compensation on a pretax basis. The Plan does not currently provide for matching contributions.

managerial  services  in  regard  to  the  Company’s  AquaRefining  facility  located  at  the  Trans-Reno  Industrial  Complex  outside  of
McCarran, Nevada ("TRIC").

The Agreement has a minimum term of two ( 2) years and upon the expiration of the initial term the Agreement automatically extends
for an additional one-year period unless either party delivers its written notice of termination no later than 180 days’ prior the end of
the then current term. Either party may terminate the Agreement on ten days’ prior written notice in the event of breach by the other
party that goes uncorrected during the notice period. Veolia may terminate the Agreement for any reason during the first six months of
the Agreement and may also terminate the Agreement in the event of the Company’s failure to provide certain funding and support to
the  AquaRefining  facility  at  TRIC. The  Agreement  contains  representations,  warranties  and  indemnities  that  are  customary  to
commercial agreements of this nature.

Pursuant to the Agreement, the Company and Veolia have agreed to enter into good faith negotiations for a longer-term version of the
Agreement that will provide for Veolia’s management and operation of the TRIC facility for a ten-year term.  The parties have agreed
to commence negotiations no later than April 1, 2020 and to use their good faith commercial best-efforts to conclude negotiations by
September 30, 2020.

In consideration of the services to be provided by Veolia under the Agreement, the Company has agreed to issue to Veolia a total of
2,350,000  shares  of  its  common  stock  in  eight  quarterly  installments  of 293,750  shares. Each  installment  is  subject  to  weighted

days preceding the date for issuance of such installment. The Company has also agreed to issue to Veolia, on the one-year anniversary

Item 9A. Controls and Procedures

(a) Evaluation 
Procedures.

of  Disclosure  Controls 

and

Our management, with the participation of our chief executive officer and chief financial officer evaluated the effectiveness of our
disclosure controls and procedures pursuant to Rule 13a-15 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”).
Based  upon  that  evaluation,  our  management,  including  our  chief  executive  officer  and  chief  financial  officer,  concluded  that  for  the
reasons  described  below  our  disclosure  controls  and  procedures  were  effective  as  of  December  31,  2018  in  ensuring  all  material
information required to be filed has been made known in a timely manner.

(b) Changes 
reporting.

in 

internal  control  over 

financial

There were no changes to our internal control over financial reporting, as defined in Rules 13a-15(f) under the Exchange Act that
occurred during the fiscal quarter ended December 31, 2018 that have materially affected, or are reasonably likely to materially affect, our
internal control over financial reporting.

(c) Management’s  report  on 

internal  controls  over 

financial

reporting.

Our  management  is  responsible  for  establishing  and  maintaining  adequate  internal  controls  over  financial  reporting,  as  defined
under  Rule  15a-15(f)  under  the  Exchange Act.  Our  management  has  assessed  the  effectiveness  of  our  internal  controls  over  financial
reporting  as  of  December  31,  2018  based  on  the  framework  established  in  Internal  Control  -  Integrated  Framework  issued  by  the
Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission  (“COSO”).  Our  internal  control  system  was  designed  to  provide
reasonable  assurance  to  our  management  and  board  of  directors  regarding  the  preparation  and  fair  presentation  of  published  financial
statements. An  internal  control  material  weakness  is  a  significant  deficiency,  or  aggregation  of  deficiencies,  that  does  not  reduce  to  a
relatively low level the risk that material misstatements in financial statements will be prevented or detected on a timely basis by employees
in  the  normal  course  of  their  work.  Our  management  assessed  the  effectiveness  of  our  internal  control  over  financial  reporting  as  of
December 31, 2018, and based on that evaluation, management concluded that our internal control over financial reporting was effective as
of December 31, 2018.

This report does not include an attestation report of our registered public accounting firm regarding internal control over financial
reporting. Management’s report was not subject to attestation by our registered public accounting firm pursuant to the rules of the Securities
and Exchange Commission that permit us to provide only management’s report in this annual report.

Item 9B. Other Information

Veolia Agreement

On February 28, 2019, the Company entered into an Operations, Maintenance and Management Agreement ("Agreement") with
Veolia  North  America  Regeneration  Services,  LLC  ("Veolia")  pursuant  to  which  Veolia  will  provide  operational,  maintenance  and
managerial services in regard to the Company’s AquaRefining facility located at the Trans-Reno Industrial Complex outside of McCarran,
Nevada ("TRIC").

Pursuant to the Agreement, we have agreed with Veolia on annual capital and operational budgets and commercialization plans,
and that the Veolia general manager will manage the operations of our AquaRefining facility at TRIC in accordance with those budgets and
plans.

Pursuant to the Agreement, we have granted Veolia the right of first refusal to manage any future AquaRefining facilities directly
owned by us on terms  substantially  similarly  to  those  in  the Agreement. We have also agreed to include Veolia in the marketing of any
potential  licensing  of  our AquaRefining  technology  to  third  parties  with  the  goal  of  assisting  Veolia  in  obtaining  an  engagement  by  the
licensee to serve as operations and management service provider for such facility.

Pursuant  to  the Agreement,  we  and  Veolia  have  agreed  to  enter  into  good  faith  negotiations  for  a  longer-term  version  of  the

Agreement that will provide for Veolia’s management and operation of the TRIC facility for a ten-year term. The parties have agreed to

commence  negotiations  no  later  than  April  1,  2020  and  to  use  their  good  faith  commercial  best-efforts  to  conclude  negotiations  by
September 30, 2020. We have also agreed to enter into good faith negotiations with Veolia for a long-term agreement concerning Veolia’s
participation in the commercial licensing and management of future AquaRefining facilities developed by licensees of Aqua Metals.  We
have agreed to commence negotiations on the long-term licensing agreement no later than December 31, 2019 and to use our good faith
commercial best-efforts to conclude negotiations by June 30, 2020.

The Agreement has a minimum term of two years and upon the expiration of the initial term the Agreement automatically extends
for an additional one-year period unless either party delivers its written notice of termination no later than 180 days’ prior the end of the
then current term. Either party may terminate the Agreement on ten days’ prior written notice in the event of breach by the other party that
goes uncorrected during the notice period. Veolia may terminate the Agreement for any reason during the first six months of the Agreement
and may also terminate the Agreement in the event of our failure to provide certain funding and support to the AquaRefining facility at
TRIC. The Agreement contains representations, warranties and indemnities that are customary to commercial agreements of this nature.

In  consideration  of  the  services  to  be  provided  by  Veolia  under  the Agreement,  we  have  agreed  to  issue  to  Veolia  a  total  of
2,350,000 shares of our common stock in eight quarterly installments of 293,750 shares. Each installment is subject to weighted average
antidilution adjustments in the event of our sale of common shares for cash consideration during the preceding quarterly period at a price
less than $2.41 per share. In addition, the number of shares to be issued in each installment shall be capped at the current market value of
$1.25 million based on the volume weighted average price of our shares over the 20 trading days preceding the date for issuance of such
installment. We  have  also  agreed  to  issue  to  Veolia,  on  the  one-year  anniversary  of  the Agreement,  warrants  to  purchase  an  additional
2,000,000 shares of our common stock at an exercise price of $5.00 per share and, on the second anniversary of the Agreement, warrants to
purchase an additional 2,000,000 shares of our common stock at an exercise price $7.00 per share. The warrants will have a term of ten

Securities Act of 1933 and Rule 506(b) thereunder.

increase Mr. Cotton’s salary to $450,000 per year, effective as of January 7, 2019.  We also agreed to provide Mr. Cotton with a change-in-

AQUA METALS, INC. 

UNDERWRITER WARRANT 

103,500 shares of Common Stock 

January 22, 2019

This UNDERWRITER WARRANT (this “Warrant”) of Aqua Metals, Inc., a corporation, duly organized and validly
existing  under  the  laws  of  the  State  of  Delaware  (the  “Company”), is  being  issued  pursuant  to  that  certain  Underwriting
Agreement,  dated  January  17,  2019  (the  “Underwriting  Agreement”), between  the  Company  and  National  Securities
Corporation (the “Underwriter”) relating to a public offering (the “Offering”) of     shares of common stock, $0.001 par value,
of the Company (the “Common Stock”) underwritten by the Underwriter.

FOR VALUE RECEIVED, the Company hereby grants to National Securities Corporation and its permitted successors
and assigns (collectively, the “Holder”) the right to purchase from the Company up to 103,500 shares of Common Stock (such
shares  underlying  this  Warrant,  the  “Warrant Shares”),  at  a  per  share  purchase  price  equal  to  $1.90  (the  “Exercise  Price”),
subject to the terms, conditions and adjustments set forth below in this Warrant.

1.

Date of Warrant Exercise. This Warrant shall become exercisable upon the later of (i) one hundred eight (180)
days after the date hereof and (ii) the day on which the Company files an amendment to its certificate of incorporation increasing
the  number  of  authorized  shares  of  Common  Stock  to  such  number  of  authorized  shares  of  Common  Stock  that  permits  this
Warrant to be exercised in full by the Holder (the “ Exercise Date”). Except  as  permitted  by  applicable  rules  of  the  Financial
Industry Regulatory Authority, Inc. (“ FINRA”), this Warrant and the underlying Warrant Shares shall not be sold, transferred,
assigned, pledged or hypothecated prior to the date that is one hundred eighty (180) days immediately following the date hereof
pursuant to FINRA Rule 5110(g)(1), except as permitted under FINRA Rule 5110(g)(2).

2.    Expiration of Warrant. This Warrant shall expire on the five (5) year anniversary of the date hereof (the “Expiration

Date”).

OC 287914083v1

3.    Exercise of Warrant. This Warrant shall be exercisable pursuant to the terms of this Section 3.

3.1    Manner of Exercise.

(a)     This Warrant may only be exercised by the Holder hereof on or after the Exercise Date and on or
prior  to  the  Expiration  Date,  in  accordance  with  the  terms  and  conditions  hereof,  in  whole  or  in  part  (but  not  as  to  fractional
shares)  with  respect  to  any  portion  of  this  Warrant,  during  the  Company’s  normal  business  hours  on  any  day  other  than  a
Saturday or a Sunday or a day on which commercial banking institutions in New York, New York are authorized by law to be
closed (a “Business Day”), by  surrender  of  this  Warrant  to  the  Company  at  its  office  maintained  pursuant  to  Section  10.2(a)
hereof,  accompanied  by  a  written  exercise  notice  in  the  form  attached  as Exhibit A to  this  Warrant  (or  a  reasonable  facsimile
thereof)  duly  executed  by  the  Holder,  together  with  the  payment  of  the  aggregate  Exercise  Price  for  the  number  of  Warrant
Shares  purchased  upon  exercise  of  this  Warrant.  Upon  surrender  of  this  Warrant,  the  Company  shall  cancel  this  Warrant
document and shall, in the event of partial exercise, replace it with a new Warrant document in accordance with Section 3.3.

(b)    Except as provided for in Section 3.1(c) below, each exercise of this Warrant must be accompanied
by  payment  in  full  of  the  aggregate  Exercise  Price  in  cash  by  check  or  wire  transfer  in  immediately  available  funds  for  the
number of Warrant Shares being purchased by the Holder upon such exercise.

sole discretion of the Holder, be paid in full or in part on a “cashless basis” at the election of the Holder:

(c)     The aggregate Exercise Price for the number of Warrant Shares being purchased may also, in the

(i)

(ii)

(iii)

in the form of Common Stock owned by the Holder (based on the Fair Market Value (as
defined below) of such Common Stock on the date of exercise);

in  the  form  of  Warrant  Shares  withheld  by  the  Company  from  the  Warrant  Shares
otherwise to be received upon exercise of this Warrant having an aggregate Fair Market
Value  on  the  date  of  exercise  equal  to  the  aggregate  Exercise  Price  of  the  Warrant
Shares being purchased by the Holder; or

by a combination of the foregoing, provided that the combined value of all cash and the
Fair  Market  Value  of  any  shares  surrendered  to  the  Company  is  at  least  equal  to  the
aggregate  Exercise  Price  for  the  number  of  Warrant  Shares  being  purchased  by  the
Holder.

For purposes of this Warrant, the term “Fair Market Value” means with respect to a particular date, the average closing
price  of  the  Common  Stock  for  the  five  (5)  trading  days  immediately  preceding  the  applicable  exercise  herein  as  officially
reported  by  the  principal  securities  exchange  on  which  the  Common  Stock  is  then  listed  or  admitted  to  trading,  or,  if  the
Common Stock is not listed or admitted to trading on any securities exchange as determined in good faith by resolution of the
Board of Directors of the Company, based on the best information available to it.

To  illustrate  a  cashless  exercise  of  this  Warrant  under  Section  3.1  (c)(ii)  (or  for  a  portion  thereof  for  which  cashless
exercise treatment is requested as contemplated by Section 3.1(c)(iii) hereof), the calculation of such exercise shall be as follows:

OC 287914083v1

2

X = Y (A-B)/A 

where:

X = the number of Warrant Shares to be issued to the Holder (rounded to the nearest whole

share).

Y =    the number of Warrant Shares with respect to which this Warrant is being exercised.

A =    the Fair Market Value of the Common Stock.

B =    the Exercise Price.

(d)     For  purposes  of  Rule  144  and  sub-section  (d)(3)(ii)  thereof,  it  is  intended,  understood,  and
acknowledged that the Common Stock issuable upon exercise of this Warrant in a cashless exercise transaction as described in
Section  3.1(c)  above  shall  be  deemed  to  have  been  acquired  at  the  time  this  Warrant  was  issued.  Moreover,  it  is  intended,
understood,  and  acknowledged  that  the  holding  period  for  the  Common  Stock  issuable  upon  exercise  of  this  Warrant  in  a
cashless exercise transaction as described in Section 3.1(c) above shall be deemed to have commenced on the date this Warrant
was issued.

3.2     When  Exercise  Effective.  Each  exercise  of  this  Warrant  shall  be  deemed  to  have  been  effected
immediately prior to the close of business on the Business Day on which this Warrant shall have been duly surrendered to the
Company as provided in Sections 3.1 and 12 hereof, and, at such time, the Holder in whose name any certificate or certificates
for Warrant Shares shall be issuable upon exercise as provided in Section 3.3 hereof shall be deemed to have become the holder
or holders of record thereof of the number of Warrant Shares purchased upon exercise of this Warrant.

3.3     Delivery of Common Stock Certificates and New Warrant.  As soon as reasonably practicable after each
exercise  of  this  Warrant,  in  whole  or  in  part,  and  in  any  event  within  three  (3)  Business  Days  thereafter,  the  Company,  at  its
expense (including the payment by it of any applicable issue taxes), will cause to be issued in the name of and delivered to the
Holder  hereof  or,  subject  to  Sections  9  and  10  hereof,  as  the  Holder  (upon  payment  by  the  Holder  of  any  applicable  transfer
taxes) may direct:

(a)     a certificate or certificates (with appropriate restrictive legends, as applicable) for the number of
duly authorized, validly issued, fully paid and non-assessable Warrant Shares to which the Holder shall be entitled upon exercise;
and

(b)     in case exercise is in part only, a new Warrant document of like tenor, dated the date hereof, for
the remaining number of Warrant Shares issuable upon exercise of this Warrant after giving effect to the partial exercise of this
Warrant  (including  the  delivery  of  any  Warrant  Shares  as  payment  of  the  Exercise  Price  for  such  partial  exercise  of  this
Warrant).

4.    Certain Adjustments. For so long as this Warrant is outstanding:

4.1    Mergers or Consolidations. If at any time after the date hereof there shall be a capital reorganization (other
than a combination or subdivision of Common Stock otherwise provided for herein) resulting in a reclassification to or change in
the  terms  of  securities  issuable  upon  exercise  of  this  Warrant  (a  “Reorganization”),  or  a  merger  or  consolidation  of  the
Company  with  another  corporation,  association,  partnership,  organization,  business,  individual,  government  or  political
subdivision thereof or a governmental agency (a “Person” or the “Persons”) (other than a merger with another Person in which
the Company is a continuing corporation and which does not result in any reclassification or change in the terms of securities
issuable upon exercise of this Warrant or a merger effected exclusively for the purpose of changing the domicile

OC 287914083v1

3

of the Company) (a “Merger”), then, as a part of such Reorganization or Merger, lawful provision and adjustment shall be made
so that the Holder shall thereafter be entitled to receive, upon exercise of this Warrant, the number of shares of stock or any other
equity  or  debt  securities  or  property  receivable  upon  such  Reorganization  or  Merger  by  a  holder  of  the  number  of  shares  of
Common Stock which might have been purchased upon exercise of this Warrant immediately prior to such Reorganization or
Merger. In any such case, appropriate adjustment shall be made in the application of the provisions of this Warrant with respect
to  the  rights  and  interests  of  the  Holder  after  the  Reorganization  or  Merger  to  the  end  that  the  provisions  of  this  Warrant
(including adjustment of the Exercise Price then in effect and the number of Warrant Shares) shall be applicable after that event,
as near as reasonably may be, in relation to any shares of stock, securities, property or other assets thereafter deliverable upon
exercise of this Warrant. The provisions of this Section 4.1 shall similarly apply to successive Reorganizations and/or Mergers.

4.2     Splits and Subdivisions; Dividends.  In  the  event  the  Company  should  at  any  time  or  from  time  to  time
effectuate a split or subdivision of the outstanding shares of Common Stock or pay a dividend in or make a distribution payable
in additional shares of Common Stock or other securities, or rights convertible into, or entitling the holder thereof to receive,
directly  or  indirectly,  additional  shares  of  Common  Stock  (hereinafter  referred  to  as  “Common  Stock  Equivalents”)  without
payment  of  any  consideration  by  such  holder  for  the  additional  shares  of  Common  Stock  or  Common  Stock  Equivalents
(including  the  additional  shares  of  Common  Stock  issuable  upon  conversion  or  exercise  thereof),  then,  as  of  the  applicable
record date (or the date of such distribution, split or subdivision if no record date is fixed), the per share Exercise Price shall be
appropriately  decreased  and  the  number  of  Warrant  Shares  shall  be  appropriately  increased  in  proportion  to  such  increase  (or
potential increase) of outstanding shares; provided, however, that no adjustment shall be made in the event the split, subdivision,
dividend or distribution is not effectuated.

4.3     Combination of Shares. If the number of shares of Common Stock outstanding at any time after the date
hereof  is  decreased  by  a  combination  of  the  outstanding  shares  of  Common  Stock,  the  per  share  Exercise  Price  shall  be
appropriately  increased  and  the  number  of  shares  of  Warrant  Shares  shall  be  appropriately  decreased  in  proportion  to  such
decrease in outstanding shares.

4.4     Adjustments  for  Other  Distributions.  In  the  event  the  Company  shall  declare  a  distribution  payable  in
securities of other Persons, evidences of indebtedness issued by the Company or other Persons, assets (excluding cash dividends
or distributions to the holders of Common Stock paid out of current or retained earnings and declared by the Company’s Board
of Directors) or options or rights not referred to in Sections 4.2 or 4.3 then, in each such case for the purpose of this Section 4.4,
upon exercise of this Warrant, the Holder shall be entitled to a proportionate share of any such distribution as though the Holder
was the actual record holder of the number of Warrant Shares as of the record date fixed for the determination of the holders of
Common Stock of the Company entitled to receive such distribution.

5.    No Impairment. The Company will not, by amendment of its certificate of incorporation or by-laws or through any
consolidation,  merger,  reorganization,  transfer  of  assets,  dissolution,  issue  or  sale  of  securities  or  any  other  voluntary  action,
avoid or seek to avoid the observance or performance of any of the terms of this Warrant, but will at all times in good faith assist
in the carrying out of all of the terms and in the taking of all actions necessary or appropriate in order to protect the rights of the
Holder against impairment.

6.    Notice as to Adjustments. With respect to each adjustment pursuant to Section 4 of this Warrant, the Company, at its
expense, will promptly compute the adjustment or re-adjustment in accordance with the terms of this Warrant and furnish the
Holder with a certificate certified and confirmed by the Secretary or Chief Financial Officer of the Company setting forth, in
reasonable detail, the event requiring the adjustment or re-adjustment and the amount of such adjustment or re-adjustment, the
method of calculation thereof and the facts upon which the adjustment or re-adjustment is based, and the Exercise Price and the
number of

OC 287914083v1

4

Warrant Shares or other securities purchasable hereunder after giving effect to such adjustment or re-adjustment, which report
shall be mailed by first class mail, postage prepaid to the Holder.

7.     Reservation of Shares.  Upon  the  Company  filing  an  amendment  to  its  certificate  of  incorporation  increasing  the
number of authorized shares of Common Stock to such number of authorized shares of Common Stock that permits this Warrant
to be exercised in full by the Holder, which increase and reservation shall be effected by the Company by no later than July 22,
2019, the Company shall, solely for the purpose of effecting the exercise of this Warrant, reserve and keep available out of its
authorized shares of Common Stock, free from all taxes, liens and charges with respect to the issue thereof and not subject to
preemptive rights of shareholders of the Company, such number of its shares of Common Stock as shall from time to time be
sufficient to effect in full the exercise of this Warrant. If at any time thereafter the number of authorized but unissued shares of
Common Stock shall not be sufficient to effect in full the exercise of this Warrant, in addition to such other remedies as shall be
available to Holder, the Company will promptly take such corporate action as may, in the opinion of its counsel, be necessary to
increase the number of authorized but unissued shares of Common Stock to such number of shares as shall be sufficient for such
purposes, including without limitation, using its Reasonable Commercial Efforts (as defined in Section 14 hereof) to obtain the
requisite shareholder approval necessary to increase the number of authorized shares of Common Stock. The Company hereby
represents and warrants that all shares of Common Stock issuable upon proper exercise of this Warrant shall be duly authorized
and, when issued and paid for upon proper exercise, shall be validly issued, fully paid and nonassessable.

8.    Registration and Listing.

8.1     Definition of Registrable Securities; Majority.  As used herein, the term “Registrable Securities”  means
any shares of Common Stock issuable upon the exercise of this Warrant until the date (if any) on which such shares shall have
been  transferred  or  exchanged  and  new  certificates  for  them  not  bearing  a  legend  restricting  further  transfer  shall  have  been
delivered  by  the  Company  and  subsequent  disposition  of  the  shares  shall  not  require  registration  or  qualification  under  the
Securities Act or any similar state law then in force. For purposes of this Warrant, the term “Majority Holders” shall mean in
excess of fifty percent (50%) of the then outstanding Warrant Shares.

8.2    Demand Registration Rights.

(a)     The  Company,  upon  written  demand  (“Demand  Notice”)  of  the  Majority  Holders,  agrees  to
register  on  one  occasion  all  of  the  Registrable  Securities  (a  “Demand  Right”).  On  such  occasion,  the  Company  will  file  a
registration  statement  or  a  post-effective  amendment  to  the  Registration  Statement  covering  the  Registrable  Securities  within
forty-five  (45)  days  after  receipt  of  a  Demand  Notice  and  use  its  Reasonable  Commercial  Efforts  to  have  such  registration
statement or post-effective amendment declared effective as soon as possible thereafter; provided, however, that the Company
shall not be required to comply with a Demand Notice if the Company has filed a registration statement with respect to which the
Holder  is  entitled  to  piggyback  registration  rights  pursuant  to  Section  8.3  hereof  and  either:  (i)  the  Holder  has  elected  to
participate in the offering covered by such registration statement or (ii) if such registration statement relates to an underwritten
primary offering of securities of the Company, until the offering covered by such registration statement has been withdrawn or
until thirty (30) days after such offering is consummated. The demand for registration may be made at any time during a period
of two and one-half years beginning six (6) months from the date hereof. The Company covenants and agrees to give written
notice of its receipt of any Demand Notice to all other registered Holders of the Warrants and/or the Registrable Securities within
ten days from the date of the receipt of any such Demand Notice.

pursuant to Section 8.2(a), but the Holders shall pay any and all underwriting

(b)     The Company shall bear all fees and expenses attendant to registering the Registrable Securities

OC 287914083v1

5

commissions and the expenses of any legal counsel selected by the Holders to represent them in connection with the sale of the
Registrable  Securities. The  Company  agrees  to  use  its  Reasonable  Commercial  Efforts  to  qualify  or  register  the  Registrable
Securities  in  such  states  as  are  reasonably  requested  by  the  Majority  Holder(s);  provided,  however,  that  in  no  event  shall  the
Company be required to register the Registrable Securities in a state in which such registration would cause (i) the Company to
be obligated to register, license or qualify to do business in such state, submit to general service of process in such state or would
subject the Company to taxation as a foreign corporation doing business in such jurisdiction or (ii) the principal stockholders of
the Company to be obligated to escrow their shares of capital stock of the Company. The Company shall cause any registration
statement or post-effective amendment filed pursuant to the Demand Right granted under Section 8.2(a) to remain effective for a
period  of  nine  consecutive  months  from  the  effective  date  of  such  registration  statement  or  post-effective  amendment. The
Holders shall only use the prospectuses provided by the Company to sell the Registrable Securities covered by such registration
statement, and will immediately cease to use any prospectus furnished by the Company if the Company advises the Holder that
such prospectus may no longer be used due to a material misstatement or omission.

8.3    Incidental Registration Rights.

(a)     If the Company proposes to register any of its securities under the Securities Act (other than in
connection with a transaction contemplated by Rule 145(a) promulgated under the Securities Act or pursuant to registration on
Form S-4 or S-8 or any successor forms) whether for its own account or for the account of any holder or holders of its shares
other  than  Registrable  Securities  (any  shares  of  such  holder  or  holders  (but  not  those  of  the  Company  and  not  Registrable
Securities) with respect to any registration are referred to herein as, “Other Shares”), the Company shall at each such time give
prompt  (but  not  less  than  thirty  (30)  days  prior  to  the  anticipated  effectiveness  thereof)  written  notice  to  the  holders  of
Registrable  Securities  of  its  intention  to  do  so. The  holders  of  Registrable  Securities  shall  exercise  the  “piggy-back”  rights
provided herein by giving written notice within ten (10) days after the receipt of any such notice (which request shall specify the
Registrable Securities intended to be disposed of by such holder). Except as set forth in Section 8.3(b), the Company will use its
Reasonable Commercial Efforts to effect the registration under the Securities Act of all of the Registrable Securities which the
Company  has  been  so  requested  to  register  by  such  holder,  to  the  extent  required  to  permit  the  disposition  of  the  Registrable
Securities so to be registered, by inclusion of such Registrable Securities in the registration statement which covers the securities
which the Company proposes to register. The Company will pay all Registration Expenses in connection with each registration of
Registrable Securities pursuant to this Section 8.3.

(b)     If the Company at any time proposes to register any of its securities under the Securities Act as
contemplated by this Section 8.3 and such securities are to be distributed by or through one or more underwriters, the Company
will, if requested by a holder of Registrable Securities, use its Reasonable Commercial Efforts to arrange for such underwriters to
include  all  the  Registrable  Securities  to  be  offered  and  sold  by  such  holder  among  the  securities  to  be  distributed  by  such
underwriters, provided that if the managing underwriter of such underwritten offering shall inform the Company by letter of its
belief that inclusion in such registration statement and/or distribution of all or a specified number of such securities proposed to
be  distributed  by  such  underwriters  would  interfere  with  the  successful  marketing  of  the  securities  being  distributed  by  such
underwriters (such letter to state the basis of such belief and the approximate number of such Registrable Securities, such Other
Shares  and  shares  held  by  the  Company  proposed  so  to  be  registered  which  may  be  distributed  without  such  effect),  then  the
Company may, upon written notice to such holder, the other holders of Registrable Securities, and holders of such Other Shares,
reduce pro rata in accordance with the number of shares of Common Stock desired to be included in such registration statement
and/or distribution (if and to the extent stated by such managing underwriter to be necessary to eliminate such effect) the number
of such Registrable Securities and Other Shares the registration and/or distribution of which shall have been requested by each
holder  thereof  so  that  the  resulting  aggregate  number  of  such  Registrable  Securities  and  Other  Shares  so  included  in  such
registration and/or distribution, together with the number of

OC 287914083v1

6

securities to be included in such registration and/or distribution for the account of the Company, shall be equal to the number of
shares stated in such managing underwriter’s letter.

8.4     Registration Procedures. Whenever the holders of Registrable Securities have properly requested that any
Registrable  Securities  be  registered  pursuant  to  the  terms  of  this  Warrant,  the  Company  shall  use  its  Reasonable  Commercial
Efforts to effect the registration for the sale of such Registrable Securities in accordance with the intended method of disposition

(b)     notify such holders of the effectiveness of each registration statement filed hereunder and prepare
and file with the SEC such amendments and supplements to such registration statement and the prospectus used in connection
therewith as may be necessary to (i) keep such registration statement effective and the prospectus included therein usable for a
period  commencing  on  the  date  that  such  registration  statement  is  initially  declared  effective  by  the  SEC  and  ending  on  the
earlier  of  (A)  the  date  when  all  Registrable  Securities  covered  by  such  registration  statement  have  been  sold  pursuant  to  the
registration  statement  or  cease  to  be  Registrable  Securities,  or  (B)  nine  months  from  the  effective  date  of  the  registration

(d)    use its Reasonable Commercial Efforts to register or qualify such Registrable Securities under such
other securities or blue sky laws of such jurisdictions as such holders reasonably request and do any and all other acts and things
which may be reasonably necessary or advisable to enable such holders to consummate the disposition in such jurisdictions of
the  Registrable  Securities  owned  by  such  holders;  provided,  however,  that  the  Company  shall  not  be  required  to:  (i)  qualify
generally to do business in any jurisdiction where it would not otherwise be required to qualify but for this subparagraph; (ii)
subject itself to taxation in any such jurisdiction; or (iii) consent to general service of process in any such jurisdiction;

(e)     notify  such  holders,  at  any  time  when  a  prospectus  relating  thereto  is  required  to  be  delivered
under the Securities Act, of the happening of any event as a result of which the prospectus included in such registration statement
contains an untrue statement of a material fact or omits any material fact necessary to make the statements therein, in light of the
circumstances in which they are made, not materially misleading, and, at the reasonable request of such holders, the Company
shall prepare a supplement or amendment to such prospectus so that, as thereafter delivered to the purchasers of such Registrable
Securities, such prospectus shall not contain an untrue statement of a material fact or omit to state any material fact necessary to
make the statements therein, in light of the circumstances in which they are made, not materially misleading;

(f)    provide a transfer agent and registrar for all such Registrable Securities not later than the effective

records, pertinent corporate documents and properties of the Company, and cause the Company’s officers, directors, managers,
employees  and  independent  accountants  to  supply  all  information  reasonably  requested  by  any  such  underwriter,  attorney,
accountant or agent in connection with such registration statement;

(h)    

otherwise  use  its  Reasonable  Commercial  Efforts  to  comply  with  all  applicable  rules  and
regulations of the SEC, and make available to its security holders, as soon as reasonably practicable, an earnings statement of the
Company, which earnings statement shall satisfy the provisions of Section 11(a) of the Securities Act and, at the option of the
Company, Rule 158 thereunder;

(i)    

in  the  event  of  the  issuance  of  any  stop  order  suspending  the  effectiveness  of  a  registration
statement,  or  of  any  order  suspending  or  preventing  the  use  of  any  related  prospectus  or  suspending  the  qualification  of  any
Registrable Securities included in such registration statement for sale in any jurisdiction, the Company shall use its Reasonable
Commercial Efforts promptly to obtain the withdrawal of such order; and

(j)     if the offering is underwritten, use its Reasonable Commercial Efforts to furnish on the date that
Registrable  Securities  are  delivered  to  the  underwriters  for  sale  pursuant  to  such  registration,  an  opinion  dated  such  date  of
counsel representing the Company for the purposes of such registration, addressed to the underwriters covering such issues as are
reasonably required by such underwriters.

8.5     Listing.  The Company shall secure the listing of the Common Stock underlying this Warrant upon each
national  securities  exchange  or  automated  quotation  system  upon  which  shares  of  Common  Stock  are  then  listed  or  quoted
(subject  to  official  notice  of  issuance)  and  shall  maintain  such  listing  of  shares  of  Common  Stock. The  Company  shall  at  all
times comply in all material respects with the Company’s reporting, filing and other obligations under the by-laws or rules of
The NASDAQ Stock Market (or such other national securities exchange or market on which the Common Stock may then be
listed, as applicable).

8.6     Expenses.  The  Company  shall  pay  all  Registration  Expenses  relating  to  the  registration  and  listing
obligations  set  forth  in  this  Section  8. For  purposes  of  this  Warrant,  the  term  “Registration  Expenses”  means:  (a)  all
registration, filing and FINRA fees, (b) all reasonable fees and expenses of complying with securities or blue sky laws, (c) all
word  processing,  duplicating  and  printing  expenses,  (d)  the  fees  and  disbursements  of  counsel  for  the  Company  and  of  its
independent public accountants, including the expenses of any special audits or “cold comfort” letters required by or incident to
such performance and compliance, (e) premiums and other costs of policies of insurance (if any) against liabilities arising out of
the public offering of the Registrable Securities being registered if the Company desires such insurance, if any, and (f) fees and
disbursements  of  one  counsel  for  the  selling  holders  of  Registrable  Securities;  provided  however,  that,  in  any  case  where
Registration Expenses are not to be borne by the Company, such expenses shall not include (and such expenses shall be borne by
the Company): (i) salaries of Company personnel or general overhead expenses of the Company, (ii) auditing fees, or (iii) other
expenses  for  the  preparation  of  financial  statements  or  other  data,  to  the  extent  that  any  of  the  foregoing  either  is  normally
prepared  by  the  Company  in  the  ordinary  course  of  its  business  or  would  have  been  incurred  by  the  Company  had  no  public
offering  taken  place. Registration  Expenses  shall  not  include  any  underwriting  discounts  and  commissions  which  may  be
incurred in the sale of any Registrable Securities and transfer taxes of the selling holders of Registrable Securities.

8.7     Information Provided by Holders.  Any holder of Registrable Securities included in any registration shall

furnish to the Company such information as the Company may reasonably request in

OC 287914083v1

8

writing,  including,  but  not  limited  to,  a  completed  and  executed  questionnaire  requesting  information  customarily  sought  of
selling security holders, to enable the Company to comply with the provisions hereof in connection with any registration referred
to in this Warrant. The Holder agrees to suspend all sales of Registrable Securities pursuant to a registration statement filed under
Section 8.3 in the event the Company notifies Holder pursuant to Section 8.4(e) that the prospectus relating thereto is no longer
current and will not resume sales under such registration statement until advised by the Company that the prospectus has been
appropriately supplemented or amended.

8.8     FINRA Public Offering System Filings. In the event that a registration statement covering the Registrable
Securities is filed, within one (1) Business Day of the filing of such registration statement, the Company will prepare and file the
selling  stockholder  resale  offering  described  in  such  registration  statement  for  review  by  FINRA  via  the  FINRA’s  Public
Offering  System  filing  system  (“Public  Offering  System  Filing”)  for  the  purpose  of  having  the  prospectus  contained  within
such  registration  statement  treated  as  a  “base  prospectus”  in  connection  with  such  resale  offering. The  Company  will  use  its
Reasonable Commercial Efforts to have the Public Offering System Filing approved by FINRA within thirty (30) days of such
filing  date.  The  Company  shall  bear  all  expenses  of  the  Public  Offering  System  Filing,  including  fees  and  expenses  of  one
counsel or other advisor to the Holder.  In all circumstances, the Company shall pay for all FINRA filing fees associated with the
Public Offering System Filing.

8.9    Effectiveness Period. The Company shall use its Reasonable Commercial Efforts to keep each registration
statement contemplated hereunder continuously effective under the Securities Act until the date which is the earlier date of when
(i) all Registrable Securities covered by such Registration Statement have been sold, (ii) all Registrable Securities covered by
such  Registration  Statement  may  be  sold  immediately  without  registration  under  the  Securities  Act  and  without  volume
restrictions pursuant to Rule 144 under the Securities Act, as determined by the counsel to the Company pursuant to a written
opinion letter to such effect, addressed and reasonably acceptable to the Company’s transfer agent and the affected holders of
Registrable Securities, or (iii) nine months from the effective date of such registration statement.

8.10    Net Cash Settlement. Notwithstanding anything herein to the contrary, in no event will the Holder hereof
be  entitled  to  receive  a  net-cash  settlement  as  liquidated  damages  in  lieu  of  physical  settlement  in  shares  of  Common  Stock,
regardless of whether the Common Stock underlying this Warrant is registered pursuant to an effective registration statement;
provided, however, that the foregoing will not preclude the Holder from seeking other remedies at law or equity for breaches by
the Company of its registration obligations hereunder.

9.    Restrictions on Transfer.

9.1    Restrictive Legends. This Warrant and each Warrant issued upon transfer or in substitution for this Warrant
pursuant to Section 10 hereof, each certificate for Common Stock issued upon the exercise of the Warrant and each certificate
issued upon the transfer of any such Common Stock shall be transferable only upon satisfaction of the conditions specified in this
Section 9. Each of the foregoing securities shall be stamped or otherwise imprinted with a legend reflecting the restrictions on
transfer set forth herein and any restrictions required under the Securities Act or other applicable securities laws.

9.2     Notice  of  Proposed  Transfer.  Prior  to  any  transfer  of  any  securities  which  are  not  registered  under  an
effective registration statement under the Securities Act  (“Restricted Securities”), which transfer may only occur if there is an
exemption  from  the  registration  provisions  of  the  Securities Act  and  all  other  applicable  securities  laws,  the  Holder  will  give
written notice to the Company of the Holder’s intention to effect a transfer (and shall describe the manner and circumstances of
the proposed transfer). The following provisions shall apply to any proposed transfer of Restricted Securities:

OC 287914083v1

9

(i)

If  in  the  opinion  of  counsel  for  the  Holder  reasonably  satisfactory  to  the  Company  the
proposed transfer may be effected without registration of the Restricted Securities under the Securities Act (which opinion shall
state in detail the basis of the legal conclusions reached therein), the Holder shall thereupon be entitled to transfer the Restricted
Securities in accordance with the terms of the notice delivered by the Holder to the Company. Each certificate representing the
Restricted  Securities  issued  upon  or  in  connection  with  any  transfer  shall  bear  the  restrictive  legends  required  by  Section  9.1
hereof.

If  the  opinion  called  for  in  (i)  above  is  not  delivered,  the  Holder  shall  not  be  entitled  to
transfer the Restricted Securities until either: (x) receipt by the Company of a further notice from such Holder pursuant to the
foregoing provisions of this Section 9.2 and fulfillment of the provisions of clause (i) above, or (y) such Restricted Securities
have been effectively registered under the Securities Act.

(ii)

9.3     Certain Other Transfer Restrictions. Notwithstanding any other provision of this Warrant: (i) prior to the
Exercise Date, this Warrant or the Restricted Securities thereunder may only be transferred or assigned to the persons permitted
under FINRA Rule 5110(g), and (ii) subject at all times to FINRA Rule 5110(g), no opinion of counsel shall be necessary for a
transfer of Restricted Securities by the holder thereof to any Person employed by or owning equity in the Holder, if the transferee
agrees in writing to be subject to the terms hereof to the same extent as if the transferee were the original purchaser hereof and
such transfer is permitted under applicable securities laws.

9.4     Termination of Restrictions.  Except as set forth in Section 9.3 hereof and subject at all times to FINRA
Rule 5110(g), the restrictions imposed by this Section 9 upon the transferability of Restricted Securities shall cease and terminate
as to any particular Restricted Securities: (a) which shall have been effectively registered under the Securities Act, or (b) when,
in  the  opinion  of  counsel  for  the  Company,  such  restrictions  are  no  longer  required  in  order  to  insure  compliance  with  the
Securities Act  or  Section  10  hereof.  Whenever  such  restrictions  shall  cease  and  terminate  as  to  any  Restricted  Securities,  the
Holder thereof shall be entitled to receive from the Company, without expense (other than applicable transfer taxes, if any), new
securities of like tenor not bearing the applicable legends required by Section 9.1 hereof.

10.    Ownership, Transfer, Sale and Substitution of Warrant.

10.1     Ownership of Warrant. The Company may treat any Person in whose name this Warrant is registered in
the  Warrant  Register  maintained  pursuant  to  Section  10.2(b)  hereof  as  the  owner  and  holder  thereof  for  all  purposes,
notwithstanding any notice to the contrary, except that, if and when any Warrant is properly assigned in blank, the Company may
(but shall not be obligated to) treat the bearer thereof as the owner of such Warrant for all purposes, notwithstanding any notice
to the contrary. Subject to Sections 9 and 10 hereof, this Warrant, if properly assigned, may be exercised by a new holder without
a new Warrant first having been issued.

10.2    Office; Exchange of Warrant.

(a)    The Company will maintain its principal office at the location identified in the prospectus relating
to the Offering or at such other offices as set forth in the Company’s most current filing (as of the date notice is to be given)
under the Securities Exchange Act of 1934, as amended, or as the Company otherwise notifies the Holder.

(b)     The Company shall cause to be kept at its office maintained pursuant to Section 10.2(a) hereof a
Warrant Register for the registration and transfer of the Warrant. The name and address of the holder of the Warrant, the transfers
thereof and the name and address of the transferee of the Warrant shall be registered in such Warrant Register.  The  Person  in
whose name the Warrant shall be so

OC 287914083v1

10

registered shall be deemed and treated as the owner and holder thereof for all purposes of this Warrant, and the Company shall
not be affected by any notice or knowledge to the contrary.

(c)    Upon the surrender of this Warrant, properly endorsed, for registration of transfer or for exchange
at  the  office  of  the  Company  maintained  pursuant  to  Section  10.2(a)  hereof,  the  Company  at  its  expense  will  (subject  to
compliance with Section 9 hereof, if applicable) execute and deliver to or upon the order of the Holder thereof a new Warrant of
like  tenor,  in  the  name  of  such  holder  or  as  such  holder  (upon  payment  by  such  holder  of  any  applicable  transfer  taxes)  may
direct,  calling  in  the  aggregate  on  the  face  thereof  for  the  number  of  shares  of  Common  Stock  called  for  on  the  face  of  the
Warrant so surrendered (after giving effect to any previous adjustment(s) to the number of Warrant Shares).

10.3     Replacement of Warrant .  Upon receipt of evidence reasonably satisfactory to the Company of the loss,
theft,  destruction  or  mutilation  of  this  Warrant  and,  in  the  case  of  any  such  loss,  theft  or  destruction  of  this  Warrant,  upon
delivery  of  indemnity  reasonably  satisfactory  to  the  Company  in  form  and  amount  or,  in  the  case  of  any  mutilation,  upon
surrender  of  this  Warrant  for  cancellation  at  the  office  of  the  Company  maintained  pursuant  to  Section  10.2(a)  hereof,  the
Company will execute and deliver, in lieu thereof, a new Warrant of like tenor and dated the date hereof.

10.4    Opinions. In connection with the sale of the Warrant Shares by Holder, the Company agrees to cooperate
with the Holder, and at the Company’s expense, to have its counsel provide any legal opinions required to remove the restrictive
legends from the Warrant Shares in connection with a sale, transfer or legend removal request of Holder.

11.    No Rights or Liabilities as Stockholder. No Holder shall be entitled to vote or be deemed the holder of any equity
securities which may at any time be issuable on the exercise hereof, nor shall anything contained herein be construed to confer
upon the Holder, as such, any of the rights of a stockholder of the Company or any right to vote for the election of directors or
upon  any  matter  submitted  to  stockholders  at  any  meeting  thereof,  or  to  give  or  withhold  consent  to  any  corporate  action
(whether  upon  any  recapitalization,  issuance  of  stock,  reclassification  of  stock,  change  of  par  value,  consolidation,  merger,
conveyance,  or  otherwise)  or  to  receive  notice  of  meetings  until  the  Warrant  shall  have  been  exercised  and  the  shares  of
Common Stock purchasable upon the exercise hereof shall have become deliverable, as provided herein.

12.    Notices. Any notice or other communication in connection with this Warrant shall be given in writing and directed
to the parties hereto as follows: (a) if to the Holder, at the address of the holder in the warrant register maintained pursuant to
Section 10 hereof, or (b) if to the Company, to the attention of its Chief Executive Officer at its office maintained pursuant to
Section  10.2(a)  hereof; provided, that  the  exercise  of  the  Warrant  shall  also  be  effected  in  the  manner  provided  in  Section  3
hereof. Notices shall be deemed properly delivered and received when delivered to the notice party (i) if personally delivered,
upon  receipt  or  refusal  to  accept  delivery,  (ii)  if  sent  via  facsimile,  upon  mechanical  confirmation  of  successful  transmission
thereof  generated  by  the  sending  telecopy  machine,  (iii)  if  sent  by  a  commercial  overnight  courier  for  delivery  on  the  next
Business Day, on the first Business Day after deposit with such courier service, or (iv) if sent by registered or certified mail, five
(5) Business Days after deposit thereof in the U.S. mail.

13.     Payment of Taxes.  The Company will pay all documentary stamp taxes attributable to the issuance of shares of
Common  Stock  underlying  this  Warrant  upon  exercise  of  this  Warrant;  provided,  however, that  the  Company  shall  not  be
required to pay any tax which may be payable in respect of any transfer involved in the transfer or registration of this Warrant or
any  certificate  for  shares  of  Common  Stock  underlying  this  Warrant  in  a  name  other  that  of  the  Holder.  The  Holder  is
responsible  for  all  other  tax  liability  that  may  arise  as  a  result  of  holding  or  transferring  this  Warrant  or  receiving  shares  of
Common Stock underlying this Warrant upon exercise hereof.

OC 287914083v1

14.     Miscellaneous. This Warrant and any term hereof may be changed, waived, discharged or terminated only by an
instrument in writing signed by the party against which enforcement of the change, waiver, discharge or termination is sought.
This Warrant shall be construed and enforced in accordance with and governed by the laws of the State of New York. Each of
the parties consents to the exclusive jurisdiction of the Federal or state courts whose districts encompass any part of the County
of  New  York  located  in  the  City  of  New  York,  New  York  in  connection  with  any  dispute  arising  under  this Agreement  and

process  in  any  such  proceeding  by  any  manner  permitted  by  law.  The  section  headings  in  this  Warrant  are  for  purposes  of
convenience only and shall not constitute a part hereof. When used herein, the term “Reasonable Commercial Efforts” means,
with respect to the applicable obligation of the Company, reasonable commercial efforts for similarly situated, publicly-traded

separation from, the Company.

11.

Release  of  Claims  by  Company.   Company  agrees  that  in  exchange  for  the  covenants  provided  by
Executive herein, such consideration represents settlement in full of all outstanding obligations owed to Company by
the  Executive  (the  “Releasee”). Company,  on  his  own  behalf,  hereby  and  forever  releases  the  Releasee  from,  and
agrees not to sue concerning, or in any manner to institute, prosecute, or pursue, any claim, complaint, charge, duty,
obligation,  demand,  or  cause  of  action  relating  to  any  matters  of  any  kind,  whether  presently  known  or  unknown,
suspected or unsuspected, that Company may possess against the Releasee arising from any omissions, acts, facts, or
damages that have occurred up until and including the Effective Date of this Agreement, including, without limitation:
any  and  all  claims  relating  to  or  arising  from  Executive’s  employment  relationship  with  the  Company  and  the
termination  of  that  relationship.  The  Company  acknowledges  that  it  has  consulted  with  legal  counsel  and  is  familiar
with  the  provisions  of  California  Civil  Code  Section  1542,  a  statute  that  otherwise  prohibits  the  release  of  unknown
claims, which provides as follows:

A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES NOT KNOW
OR  SUSPECT  TO  EXIST  IN  HIS  OR  HER  FAVOR  AT  THE  TIME  OF  EXECUTING  THE  RELEASE,
WHICH  IF  KNOWN  BY  HIM  OR  HER  MUST  HAVE  MATERIALLY  AFFECTED  HIS  OR  HER
SETTLEMENT WITH THE DEBTOR.

Company,  being  aware  of  said  code  section,  agrees  to  expressly  waive  any  rights  it  may  have  thereunder,  as

well as under any other statute or common law principles of similar effect.

12.

Trade  Secrets  and  Confidential  Information/Company  Property .  Executive  reaffirms  and  agrees  to
observe  and  abide  by  the  terms  of  the  Confidentiality  Agreement,  specifically  including  the  provisions  therein
regarding  nondisclosure  of  the  Company’s  trade  secrets  and  confidential  and  proprietary  information,  and  non-
solicitation of Company employees. Executive’s signature below constitutes his certification under penalty of perjury
that  he  will  make  reasonable  efforts  to,  within  ten  (10)  business  days  after  the  Effective  Date  return  or  destroy  all
documents and other items provided to Executive by the Company, developed or obtained by Executive in connection
with his employment with the Company, or otherwise belonging to the Company.

13.

No Cooperation. Executive agrees that he will not knowingly encourage, counsel, or assist any attorneys
or  their  clients  in  the  presentation  or  prosecution  of  any  disputes,  differences,  grievances,  claims,  charges,  or
complaints by any third party against any of the Releasees, unless under a subpoena or other court order to do so or as
related directly to the ADEA waiver in this Agreement. Executive agrees both to immediately notify the Company upon
receipt of any such subpoena or court order, and to furnish, within three (3) business days of its receipt, a copy of such
subpoena or other court order. If approached by anyone for counsel or assistance in the presentation or prosecution of
any disputes, differences, grievances, claims, charges, or complaints against any of the Releasees, Executive shall state
no more than that he cannot provide counsel or assistance.

14.

Non-Disparagement.  Executive  agrees  that  Executive  will  not  in  any  way  disparage  the  name  or
reputation of the Company, including: (1) Executive agrees not to make any derogatory or negative remarks about the
Company; (2) Executive agrees not to make any negative or derogatory remarks about the Releasees; and (3) Executive

agrees  not  to  make  any  remarks  about  any  disputes  Executive  has  had  with  the  Company  or  the  Releasees. The
Company agrees that the Company and its current and future executive officers and directors (its “Executive Officers
and Directors”), will not in any way disparage the name or reputation of the Executive, including (1) the Company and
its Executive Officers and Directors agree not to make any derogatory or negative remarks about Executive; and (2) the
Company  and  its  Executive  Officers  and  Directors  agree  not  to  make  any  remarks  about  any  disputes  they  have  had
with the Executive.

15.

Breach.  In  addition  to  the  rights  provided  in  the  “Attorneys’  Fees”  section  below,  Executive
acknowledges and agrees that upon receiving written notice of a material breach of the Agreement from the Company
and  such  breach  is  not  cured  by  Executive  within  three  business  days,  or  is  not  capable  of  being  cured,  unless  such
breach constitutes a legal action by Executive asserting Protected Rights defined hereing, or challenging or seeking a
determination  in  good  faith  of  the  validity  of  the  waiver  herein  under  the  ADEA,  or  of  any  provision  of  the
Confidentiality Agreement  shall  entitle  the  Company  immediately  to  cease  providing  the  consideration  provided  to
Executive under this Agreement and to obtain damages, except as provided by law.

16.

No Admission of Liability . The Parties understands and acknowledges that this Agreement constitutes a
compromise  and  settlement  of  any  and  all  actual  or  potential  disputed  claims. No  action  taken  by  the  Parties  hereto,
either previously or in connection with this Agreement, shall be deemed or construed to be (a) an admission of the truth
or falsity of any actual or potential claims or (b) an acknowledgment or admission by the Parties of any fault or liability
whatsoever.

17.

Non-Solicitation. During Executive’s employment with the Company, Executive came into contact and
became  familiar  with  the  Company’s  employees,  and  learned  about  their  knowledge,  skills,  abilities,  salaries,
commissions,  benefits,  and  other  matters  with  respect  to  such  employees,  all  of  which  is  not  generally  known  to  the
public  but  has  been  developed  or  compiled  by  the  Company  at  its  great  effort  and  expense. To  that  end,  Executive
Agrees that for a period of one (1) year following his Termination Date, Executive shall not, on his own behalf or on
behalf of any other person, partnership, association, corporation, or other entity, solicit, encourage, or in any manner
induce any employee of the Company to leave his or her employment with the Company for any reason.

18.

Future  Cooperation.  The  Parties  agree  that  certain  matters  in  which  the  Executive  has  been  involved
during the Executive’s employment may need the Executive’s cooperation with the Employer in the future including,
but not limited to, any assignments of intellectual property, and any and all other matters that require his cooperation.
Accordingly, following the Termination Date, to the extent reasonably requested by the Company, the Executive shall
cooperate with the Employer in connection with such matters arising out of the Executive’s service to the Employer,
provided  that  the  Employer  shall  make  reasonable  efforts  to  minimize  disruption  of  the  Executive’s  other  activities.
During  such  time,  Executive  shall  make  himself  reasonably  available  to  the  Company,  via  e-mail,  telephone,  or  in-
person at mutually acceptable times, to provide additional services and/or cooperate with the Company with respect to
business  issues  and  other  matters  (the  “Post-Termination  Services”). Executive  will  be  compensated  for  the  time  he
actually spends, if any, providing the requested Post-Termination Services, if any, at an hour rate of $288 (pro-rated for
partial hours) (the “Consulting Fees”). Executive shall submit weekly invoices to the Company for any Consulting Fees
earned  related  to  the  Post-Termination  Services,  which  invoice  shall  set  forth  the  dates  and  hours  that  Executive
actually  provided  Post-Termination  Services  at  the  request  of  an  authorized  officer  of  the  Company  and  the  total
Consulting Fees claimed for such week. The Company shall pay any Consulting Fees earned by Executive within ten
(10) days of the date of receipt by the Company of Executive’s invoice therefor.  Executive and the Company agree that
in  furnishing  any  Post-Termination  Services,  Executive  will  be  acting  as  an  independent  contractor  and,  accordingly
Executive will have no authority to act on behalf of the Company (or any of its affiliates) or bind the Company (or any
of its affiliates). While providing Post-Termination Services, if any, Executive will not be considered to have employee
status  for  federal  or  state  tax  purposes,  for  purposes  of  employee  benefit  plans  or  other  benefits  applicable  to  the
Company’s  employees  generally  or  for  any  other  purposes.  While  providing  Post-Termination  Services,  if  any,  the
Company  shall  not  pay  any  contributions  to  Social  Security,  unemployment  insurance,  federal  or  state  withholding
taxes, or provide any other contributions or benefits which might be expected in an employer-employee relationship,
and Executive expressly waives any right to such participation or coverage. Executive agrees that Executive shall make
such contributions and pay applicable taxes, and hereby agrees to indemnify and hold harmless the Company and all
Releasees from and against any costs, fees, damages or penalties assessed against the Company or any Releasees by
virtue of Executive’s failure to make such contributions or payments.

19.

Costs. The Parties shall each bear their own costs, attorneys’ fees, and other fees incurred in connection

with the preparation of this Agreement.

20.

ARBITRATION. THE PARTIES AGREE THAT ANY AND ALL DISPUTES ARISING OUT OF
THE  TERMS  OF  THIS  AGREEMENT,  THEIR  INTERPRETATION,  AND  ANY  OF  THE  MATTERS  HEREIN
RELEASED,  SHALL  BE  SUBJECT  TO  ARBITRATION  IN  ALAMEDA  COUNTY,  CALIFORNIA  BEFORE
JUDICIAL  ARBITRATION  &  MEDIATION  SERVICES  (“JAMS”),  PURSUANT  TO  ITS  EMPLOYMENT
ARBITRATION RULES & PROCEDURES (“JAMS RULES”). THE ARBITRATOR MAY GRANT INJUNCTIONS
AND OTHER RELIEF IN SUCH DISPUTES. THE ARBITRATOR SHALL ADMINISTER AND CONDUCT ANY
ARBITRATION  IN  ACCORDANCE  WITH  CALIFORNIA  LAW,  INCLUDING  THE  CALIFORNIA  CODE  OF
CIVIL  PROCEDURE,  AND  THE  ARBITRATOR  SHALL  APPLY  SUBSTANTIVE  AND  PROCEDURAL
CALIFORNIA  LAW  TO ANY  DISPUTE  OR  CLAIM,  WITHOUT  REFERENCE  TO ANY  CONFLICT-OF-LAW
PROVISIONS  OF  ANY  JURISDICTION.  TO  THE  EXTENT  THAT  THE  JAMS  RULES  CONFLICT  WITH
CALIFORNIA  LAW,  CALIFORNIA  LAW  SHALL  TAKE  PRECEDENCE.  THE  DECISION  OF  THE
ARBITRATOR SHALL BE FINAL, CONCLUSIVE, AND BINDING ON THE PARTIES TO THE ARBITRATION.

THE PARTIES AGREE THAT THE PREVAILING PARTY IN ANY ARBITRATION SHALL BE ENTITLED TO
INJUNCTIVE RELIEF IN ANY COURT OF COMPETENT JURISDICTION TO ENFORCE THE ARBITRATION
AWARD.  THE  PARTIES  TO  THE ARBITRATION  SHALL  EACH  PAY AN  EQUAL  SHARE  OF  THE  COSTS
AND  EXPENSES  OF  SUCH  ARBITRATION,  AND  EACH  PARTY  SHALL  SEPARATELY  PAY  FOR  ITS
RESPECTIVE COUNSEL FEES AND EXPENSES; PROVIDED, HOWEVER, THAT THE ARBITRATOR SHALL
AWARD  ATTORNEYS’  FEES  AND  COSTS  TO  THE  PREVAILING  PARTY,  EXCEPT  AS  PROHIBITED  BY
LAW. THE PARTIES HEREBY AGREE TO WAIVE THEIR RIGHT TO HAVE ANY DISPUTE BETWEEN THEM
RESOLVED IN A COURT OF LAW BY A JUDGE OR JURY. NOTWITHSTANDING THE FOREGOING, THIS
SECTION  WILL  NOT  PREVENT  EITHER  PARTY  FROM  SEEKING  INJUNCTIVE  RELIEF  (OR ANY  OTHER
PROVISIONAL  REMEDY)  FROM  ANY  COURT  HAVING  JURISDICTION  OVER  THE  PARTIES  AND  THE
SUBJECT  MATTER  OF  THEIR  DISPUTE  RELATING  TO  THIS  AGREEMENT  AND  THE  AGREEMENTS
INCORPORATED  HEREIN  BY  REFERENCE.  SHOULD  ANY  PART  OF  THE  ARBITRATION  AGREEMENT
CONTAINED  IN  THIS  PARAGRAPH  CONFLICT  WITH  ANY  OTHER  ARBITRATION  AGREEMENT
BETWEEN  THE  PARTIES,  THE  PARTIES  AGREE  THAT  THIS  ARBITRATION  AGREEMENT  SHALL
GOVERN.

21.

Tax  Consequences .  The  Company  makes  no  representations  or  warranties  with  respect  to  the  tax
consequences of the payments and any other consideration provided to Executive or made on his behalf under the terms
of  this Agreement. Executive agrees and understands that he is responsible for payment, if any, of local, state, and/or
federal taxes on the payments and any other consideration provided hereunder by the Company and any penalties or
assessments thereon. Executive further agrees to indemnify and hold the Company harmless from any claims, demands,
deficiencies,  penalties,  interest,  assessments,  executions,  judgments,  or  recoveries  by  any  government  agency  against
the Company for any amounts claimed due on account of (a) Executive’s failure to pay or delayed payment of federal
or state taxes, or (b) damages sustained by the Company by reason of any such claims, including attorneys’ fees and
costs.

22.

Section 409A. The Parties intend that upon the Separation Date, Executive will have a “separation from
service” within the meaning of Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”) and the
final  regulations  and  official  guidance  thereunder  (“Section  409A”).  The  provisions  of  this  Agreement  and  all
compensation  and  benefits  provided  for  under  this Agreement  are  intended  to  comply  with  Section  409A  and  any
ambiguities herein will be interpreted to so comply and/or be exempt from Section 409A. Each payment and benefit to
be  paid  or  provided  under  this  Agreement  is  intended  to  constitute  a  series  of  separate  payments  for  purposes  of
Section 1.409A-2(b)(2) of the Treasury Regulations. The Company and Executive will work together in good faith to
consider either (i) amendments to this Agreement; or (ii) revisions to this Agreement with respect to the payment of any
awards, which are necessary or appropriate to avoid imposition of any additional tax or income recognition prior to the
actual payment to Executive under Section 409A. In no event will the Company reimburse Executive for any taxes that
may be imposed on Executive under Section 409A or any other provision of the Code with respect to any payments or
benefits Executive may receive from the Company under this Agreement or under any other agreement or arrangement.

23.

Authority. The Company represents and warrants that the undersigned has the authority to act on behalf
of  the  Company  and  to  bind  the  Company  and  all  who  may  claim  through  it  to  the  terms  and  conditions  of  this
Agreement. Executive  represents  and  warrants  that  he  has  the  capacity  to  act  on  his  own  behalf  and  on  behalf  of  all
who  might  claim  through  him  to  bind  them  to  the  terms  and  conditions  of  this Agreement. Each  Party  warrants  and
represents that there are no liens or claims of lien or assignments in law or equity or otherwise of or against any of the
claims or causes of action released herein.

24.

No Representations. Executive represents that he has had an opportunity to consult with an attorney, and
has carefully read and understands the scope and effect of the provisions of this Agreement. Executive has not relied
upon any representations or statements made by the Company that are not specifically set forth in this Agreement.

25.

Severability.  In  the  event  that  any  provision  or  any  portion  of  any  provision  hereof  or  any  surviving
agreement  made  a  part  hereof  becomes  or  is  declared  by  a  court  of  competent  jurisdiction  or  arbitrator  to  be  illegal,
unenforceable,  or  void,  this Agreement  shall  continue  in  full  force  and  effect  without  said  provision  or  portion  of
provision.

26.

Attorneys’ Fees . Except  with  regard  to  a  legal  action  challenging  or  seeking  a  determination  in  good
faith of the validity of the waiver herein under the ADEA, in the event that either Party brings an action to enforce or
effect its rights under this Agreement, the prevailing Party shall be entitled to recover its costs and expenses, including
the costs of mediation, arbitration, litigation, court fees, and reasonable attorneys’ fees incurred in connection with such
an action.

27.

Entire  Agreement.  This  Agreement  represents  the  entire  agreement  and  understanding  between  the
Company  and  Executive  concerning  the  subject  matter  of  this  Agreement  and  Executive’s  employment  with  and
separation from the Company and the events leading thereto and associated therewith, and supersedes and replaces any
and  all  prior  agreements  and  understandings  concerning  the  subject  matter  of  this  Agreement  and  Executive’s
relationship with the Company, with the exception of the Confidentiality Agreement and the Stock Agreements, except
as modified herein.

28.

No Oral Modification. This Agreement may only be amended in a writing signed by Executive and the

Company’s Chief Executive Officer.

29.

Governing Law. This Agreement shall be governed by the laws of the State of California, without regard
for  choice-of-law  provisions. Executive  consents  to  personal  and  exclusive  jurisdiction  and  venue  in  the  State  of
California.

30.

Effective Date. Executive understands that this Agreement shall be null and void if not executed by him
within  twenty  one  (21)  days.  Each  Party  has  seven  (7)  days  after  that  Party  signs  this Agreement  to  revoke  it. This
Agreement will become effective on the eighth (8th) day after Executive signed this Agreement, so long as it has been
signed by the Parties and has not been revoked by either Party before that date (the “Effective Date”).

31.

Counterparts. This Agreement may be executed in counterparts and by facsimile, and each counterpart
and facsimile shall have the same force and effect as an original and shall constitute an effective, binding agreement on
the part of each of the undersigned.

32.

Voluntary Execution of Agreement . Executive understands and agrees that he executed this Agreement
voluntarily, without any duress or undue influence on the part or behalf of the Company or any third party, with the full
intent of releasing all of his claims against the Company and any of the other Releasees. Executive acknowledges that:
