Business Segments

We operate in two business segments; the manufacturing of various specialty petrochemical products and the manufacturing of specialty
synthetic waxes.

Our  specialty  petrochemical  products  segment  is  conducted  through  SHR,  a  Texas  corporation.  SHR  owns  and  operates  a  specialty
petrochemical  facility  near  Silsbee,  Texas  which  produces  high  purity  hydrocarbons  and  other  petroleum  based  products  including
isopentane, normal pentane, isohexane and hexane. These products are used in the production of polyethylene, packaging, polypropylene,
expandable  polystyrene,  poly-iso/urethane  foams,  crude  oil  from  the  Canadian  tar  sands,  and  in  the  catalyst  support  industry.      Our
specialty petrochemical products are typically transported to customers by rail car, tank truck, iso-container, and by ship. SHR owns all of
the capital stock of GSPL, a Texas corporation, which owns and operates pipelines that connect the SHR facility to a natural gas line, to
SHR's truck and rail loading terminal and to a major petroleum products pipeline owned by an unaffiliated third party. SHR also provides
custom processing services.

Our specialty synthetic wax segment is conducted through TC, a Texas corporation, located in Pasadena, Texas which produces specialty
polyethylene and poly alpha olefin waxes and provides custom processing services. The specialty polyethylene waxes are used in markets
from  paints  and  inks  to  adhesives,  coatings,  and  PVC  lubricants.  The  highly  specialized  synthetic  poly  alpha  olefin  waxes  are  used  in
applications  such  as  toner  in  printers  and  as  additives  for  candles.  These  waxes  are  sold  in  solid  form  as  pastilles  or,  for  large  adhesive
companies, in bulk liquid form.

See Note 17 to the Consolidated Financial Statements for more information.

United States Specialty Petrochemical Operations

SHR's  specialty  petrochemical  facility  is  located  in  Silsbee,  Texas  approximately  30  miles  north  of  Beaumont  and  90  miles  east  of
Houston. The facility consists of eight operating units which, while interconnected, make distinct products through differing processes: (i) a
Penhex Unit; (ii) a Reformer Unit; (iii) a Cyclo-pentane Unit; (iv) an Advanced Reformer unit; (v) an Aromatics Hydrogenation Unit; (vi) a
White  Oil  Fractionation  Unit;  (vii)  a  Hydrocarbon  Processing  Demonstration  Unit;  and  (viii)  a  P-Xylene  Unit. All  of  these  units  are
currently in operation. The Penhex Unit currently has the permitted capacity to process approximately 11,000 barrels per day of fresh feed.
The Reformer Unit, the Advanced Reformer unit, and the Cyclo-Pentane Unit further process streams produced by the Penhex Unit. The
Aromatics Hydrogenation Unit was taken out of service and decommissioned in 2018 with the start up of the new Advanced Reformer unit.
The White Oils Fractionation Unit has a capacity of approximately 3,000 barrels per day. The Hydrocarbon Processing Demonstration Unit
has  a  capacity  of  approximately  300  gallons  per  day.  The  P-Xylene  Unit  has  a  capacity  of  approximately  20,000  pounds  per  year.  The
facility generally consists of equipment commonly found in most petrochemical facilities such as fractionation towers and hydrogen treaters
except the facility is adapted to produce specialized products that are high purity and very consistent with precise specifications that are
utilized in the petrochemical industry as solvents, additives, blowing agents and cooling agents. We produce eight distinct product streams
and market several combinations of blends as needed in various customer applications. We do not produce motor fuel products or any other
products commonly sold directly to retail consumers or outlets.

We  believe  we  are  positioned  to  benefit  from  capital  investments  that  we  have  recently  completed.  We  now  have  sufficient  pentane
capacity to maintain our share of market growth for the foreseeable future. We believe that the Advanced Reformer unit will contribute to
increased revenue and gross margin over time and as we improve reliability. While petrochemical prices are volatile on a short-term basis,
and volumes depend on the demand of our customers' products and overall customer efficiency, our investment decisions are based on our
long-term business strategy and outlook.

During 2015, we constructed a new unit which is part of the Penhex Unit, D Train, which began production in the fourth quarter of 2015.
The D Train expansion increased our capacity by approximately 6,000 barrels per day of fresh feed. Our present total capacity is 13,000
barrels per day of fresh feed; however, we are currently only permitted to process 11,000 barrels per day. During 2018, we constructed a
4,000  barrels  per  day Advanced  Reformer  unit  to  increase  our  capability  to  upgrade  byproducts  produced  from  the  PenHex  Unit  and  to
provide security of hydrogen supply to the plant.

Products from the Penhex Unit, Reformer Unit, Advanced Reformer unit, and Cyclo-pentane Unit are marketed directly to the customer by
our marketing personnel. The Penhex Unit had a utilization rate during 2018 of approximately 56% based upon 11,000 barrels per day of
capacity. The Penhex Unit had a utilization rate during 2017 of approximately 53% based upon 11,000 barrels per day of capacity. The
Penhex Unit had a utilization rate during 2016 of approximately 48% based upon 11,000 barrels per day.

Penhex Unit capacity is now configured in three independent process units. The three unit configuration improves reliability by reducing
the amount of total down time due to mechanical and other factors. This configuration also allows us to use spare capacity for new product
development.  The  Advanced  Reformer  and  Reformer  units  are  operated  as  needed  to  support  the  Penhex  and  Cyclo-pentane  Units.
Consequently,  utilization  rates  of  these  units  are  driven  by  production  from  the  Penhex  Unit.  Operating  utilization  rates  are  affected  by
product demand, raw material composition, mechanical integrity, and unforeseen natural occurrences, such as weather events. The nature
of the petrochemical process demands periodic shut-downs for de-coking and other mechanical repairs.

In  February  2018,  while  attempting  to  commission  the  new Advanced  Reformer  unit,  the  unit  overheated  and  ignited  a  fire.  There  was
damage to all six heaters in the unit, and the damaged equipment had to be replaced. The total repair cost was approximately $3.5 million.
Our insurers covered costs over our $1 million deductible. On July 9, 2018, we announced the safe and successful start up of the Advanced
Reformer  unit.  In  mid-September  2018  the  Silsbee  facility  suffered  a  power  outage  causing  a  shutdown  of  the  plant,  including  the
Advanced Reformer unit. In October 2018, after extensive engineering review and consultations with the technology licensor of the Unit it
was determined that the unit's catalyst required replacement. We completed the catalyst replacement and successfully restarted the Unit in
December 2018. The cost of the catalyst replacement was approximately $3 million. During the time the Advanced Reformer unit was not
operation  due  to  the  catalyst  replacement  work,  we  incurred  losses  as  a  result  of  sales  of  byproducts  at  prices  well  below  the  cost  of
feedstock.

In  support  of  the  specialty  petrochemical  operation,  we  own  approximately  100  storage  tanks  with  total  capacity  approaching  285,000
barrels,  and  127  acres  of  land  at  the  plant  site,  92  acres  of  which  are  developed.  We  also  own  a  truck  and  railroad  loading  terminal
consisting  of  storage  tanks,  nine  rail  spurs,  and  truck  and  tank  car  loading  facilities  on  approximately  63  acres  of  which  33  acres  are
developed. As a result of various expansion programs and the toll processing contracts, essentially all of the standing equipment at SHR is
operational. We have various surplus equipment stored on-site which may be used in the future to assemble additional processing units as
needs arise.

We  obtain  our  feedstock  requirements  from  a  sole  supplier.  The  agreement  is  primarily  a  logistics  arrangement.  The  supplier  buys  or
contracts for material and utilizes their tank and pipeline connections to transport into our pipeline. The supplier's revenue above feed cost
is primarily related to the cost and operation of the tank, pipelines, and equipment. A contract was signed in August 2015 with a seven year
term  with  subsequent  one  year  renewals  unless  canceled  by  either  party  with  180  days'  notice.  In  2015,  a  pipeline  connection  to  the
supplier's dock was added to give alternative means of receiving feedstock.

GSPL owns and operates three 8-inch diameter pipelines and five 4-inch diameter pipelines, aggregating approximately 70 miles in length
connecting SHR's facility to (1) a natural gas line, (2) SHR's truck and rail loading terminal and (3) a major petroleum products pipeline
system  owned  by  an  unaffiliated  third  party. All  pipelines  are  operated  within  Texas  Railroad  Commission  and  DOT  regulations  for
maintenance and integrity.

We sell our products predominantly to large domestic and international companies. Products are marketed via personal contact and through
continued  long  term  relationships.  Sales  personnel  visit  customer  facilities  regularly  and  also  attend  various  petrochemical  conferences
throughout the world. We also have a website with information about our products and services. We utilize both formula and non-formula
based pricing depending upon a customer's requirements. Under formula pricing the price charged to the customer is primarily based on a
formula which includes as a component the average cost of feedstock over the prior month. With this pricing mechanism, product prices
move  in  conjunction  with  feedstock  prices.  However,  because  the  formulas  use  an  average  feedstock  price  from  the  prior  month,  the
movement of prices will trail the movement of costs, and formula prices may or may not reflect our actual feedstock cost for the month
during which the product is actually sold. In addition, while

2

Table of Contents

formula  pricing  can  reduce  product  margins  during  periods  of  increasing  feedstock  costs,  during  periods  of  decreasing  feedstock  costs
formula  pricing  will  follow  feed  costs  down  but  will  retain  higher  margins  during  the  period  by  trailing  the  movement  of  costs  by
approximately 30 days. During 2018 and 2017, sales to one customer exceeded 10% of our consolidated revenues. During 2018 and 2017,
sales to ExxonMobil and their affiliates were 17% and 20% of total revenues, respectively. These sales represented multiple products sold
to multiple facilities.

United States Mineral Interests

Our only mineral interest in the United States is our 55% ownership interest in an inactive corporation, PEVM. PEVM's properties include
48 patented and 5 unpatented claims totaling approximately 1,500 acres. All of the claims are located in Lincoln County, NV.

At  this  time,  neither  we  nor  PEVM  have  plans  to  develop  the  mining  assets  near  Pioche,  NV.  Periodically  proposals  are  received  from
outside  parties  who  are  interested  in  developing  or  using  certain  assets.  We  do  not  anticipate  making  any  significant  domestic  mining
capital expenditures.

Environmental

Matters pertaining to the environment are discussed in Part I, Item 1A. Risk Factors, Part II, Item 7. Management's Discussion and Analysis
of Financial Condition and Results of Operations and Notes 2 and 14 to the Consolidated Financial Statements.

In 1993 during remediation of a small spill area, the Texas Commission on Environmental Quality ("TCEQ") required SHR to drill a well
to check for groundwater contamination under the spill area. Two pools of hydrocarbons were discovered to be floating on the groundwater
at a depth of approximately 25 feet. One pool is under the site of a former gas processing plant owned and operated by Sinclair, Arco and
others  before  its  purchase  by  SHR  in  1981. Analysis  of  the  material  indicates  it  entered  the  ground  prior  to  SHR's  acquisition  of  the
property. The other pool is under the original SHR facility and analysis indicates the material was deposited decades ago. Tests conducted
have determined that the hydrocarbons are contained on the property and not migrating in any direction. The recovery process was initiated
in  June  1998  and  approximately  $53,000  was  spent  setting  up  the  system.  The  recovery  is  proceeding  as  planned  and  is  expected  to
continue  for  many  years  until  the  pools  are  reduced  to  acceptable  levels.  Expenses  of  recovery  and  periodic  migration  testing  are  being
recorded as normal operating expenses. Expenses for future recovery are expected to stabilize and be less per annum than the initial set up
cost, although there is no assurance of this effect. The light hydrocarbon recovered from the former gas plant site is compatible with our
normal  Penhex  feedstock  and  is  accumulated  and  transferred  into  the  Penhex  feedstock  tank.  The  material  recovered  from  under  the
original SHR site is accumulated and sold as a by-product. Approximately 144, 80, and 70 barrels were recovered during 2018, 2017, and
2016,  respectively.  The  recovered  material  had  a  value  of  approximately  $5,800,  $4,200,  and  $3,200  during  2018,  2017,  and  2016,
respectively. Consulting engineers estimate that as much as 20,000 barrels of recoverable material may be available to us for use in our
process or for sale. The final volume present and the ability to recover it are both highly speculative issues due to the area over which it is
spread  and  the  fragmented  nature  of  the  pockets  of  hydrocarbon.  We  have  drilled  additional  wells  periodically  to  further  delineate  the
boundaries of the pools and to ensure that migration has not taken place. These tests confirmed that no migration of the hydrocarbon pools
has occurred. The TCEQ has deemed the current action plan acceptable and reviews the plan on a semi-annual basis.

Personnel

The number of our regular, U.S. based employees was approximately 280, 324, and 310 for the years ended December 31, 2018, 2017, and
2016, respectively. Of these employees, none are covered by collective bargaining agreements. Regular  employees  are  defined  as  active
executive, management, professional, technical and wage employees who work full time or part time for the Company and are covered by
our benefit plans and programs. Our workforce has decreased primarily due to completion of capital projects at our facilities including a
workforce downsizing at SHR in December 2018.

Competition

The specialty petrochemical, specialty wax, and mining industries are highly competitive. There is competition within the industries and
also with other industries in supplying the chemical and mineral needs of both industrial and individual consumers. We compete with other
firms in the sale or purchase of needed goods and services and employ all methods of competition which are lawful and appropriate for
such purposes. See further discussion in Part I, Item 1A. Risk Factors.

Investment in AMAK

As of December 31, 2018, we owned a 33.4% interest in AMAK.

Location, Access and Transportation.

The  facility  site  is  located  in  Najran  province  in  southwestern  Saudi Arabia.  Najran,  the  capital  of  the  province  of  the  same  name,  is
approximately 700 km southeast of Jeddah. The site is located 145 km northwest of Najran, midway between the outpost of Rihab and the
district town of Sufah. A modern, paved highway extends from Najran through the town of Habuna passing by the project site and on to
Sufah. Another modern, paved highway extends west from the town of Tirima about 30 km to the Asir provincial line, becomes a four-lane
divided highway, and intersects with a highway leading to Khamis Mushait and Abha. A joining highway then extends down the western
slope of the Sarawat mountains to the coastal highway which follows the coast south to the Port of Jazan. The latter is the route AMAK's
trucks carry concentrate to the port for export.

Conditions to Retain Title.

The  Saudi  government  granted  the  Company  a  mining  lease  for  the Al  Masane  area  comprising  approximately  44  square  kilometers  or
approximately 10,870 acres on May 22, 1993 (the "Lease") under Royal Decree No. M/17. The Lease was assigned to AMAK in December
2008. The initial term of the Lease is thirty years beginning May 22, 1993, with AMAK having the option to renew or extend the term of
the  Lease  for  additional  periods  not  to  exceed  twenty  years.  Under  the  Lease, AMAK  is  obligated  to  pay  advance  surface  rental  in  the
amount of 10,000 Saudi riyals (approximately $2,667 at the current exchange rate) per square kilometer per year (approximately $117,300
annually) during the term of the Lease. In addition, AMAK must pay income tax in accordance with the laws of Saudi Arabia and pay all
infrastructure costs. The Lease gives the Saudi Arabian government priority to purchase any gold production from the project, as well as
the right to purchase up to 10% of the annual production of other minerals on the same terms and conditions then available to other similar
buyers  and  at  current  prices  then  prevailing  in  the  free  market.  Furthermore,  the  Lease  contains  provisions  requiring  that  preferences  be
given  to  Saudi Arabian  suppliers  and  contractors  and  that AMAK  employ  Saudi Arabian  citizens  and  provide  training  to  Saudi Arabian
personnel. In November 2015 AMAK received notification of final approval for additional licenses and leases. The approval includes an
additional 151 square kilometers ("km2") of territory contiguous to AMAK's current 44 km2 mine. The new territory comprises the Guyan
and Qatan exploration licenses covering 151 km2, and within the Guyan exploration license, a 10 km2 mining lease, which has potential for
significant  gold  recovery.  Under  the  new  leases, AMAK  is  required  to  pay  surface  rental  of  SR  110,000  (approximately  $29,333)  for  a
period of 20 years expiring in 2035.

Rock Formations and Mineralization.

Three  mineralized  zones,  the  Saadah, Al  Houra  and  Moyeath,  have  been  outlined  by  diamond  drilling.  The  Saadah  and Al  Houra  zones
occur  in  a  volcanic  sequence  that  consists  of  two  mafic-felsic  sequences  with  interbedded  exhalative  cherts  and  metasedimentary  rocks.
The Moyeath zone was discovered after the completion of underground development in 1980. It is located along an angular unconformity
with underlying felsic volcanics and shales. The principle sulphide minerals in all of the zones are pyrite, sphalerite, and chalcopyrite. The
precious metals occur chiefly in tetrahedrite and as tellurides and electrum.

Description of Current Property Condition.

The AMAK facility includes an underground mine, ore-treatment plant and related infrastructures. The ore-treatment plant is comprised of
primary  crushing,  ore  storage,  SAG  milling  and  pebble  crushing,  secondary  ball  milling,  pre-flotation,  copper  and  zinc  flotation,
concentrate  thickening,  tailings  filtration,  cyanide  leaching,  reagent  handling,  tailings  dam  and  utilities.  Related  infrastructure  includes  a
300 man capacity camp for single status accommodation for expatriates and Saudi Arabian employees, an on-site medical facility, a service
building  for  300  employees,  on-site  diesel  generation  of  15  megawatts,  potable  water  supply  primarily  from  an  underground  aquifer,
sewage treatment plant and an assay laboratory. The facilities at the Port of Jazan are comprised of unloading facilities, concentrate storage
and reclamation and ship loading facilities. The above-ground ore processing facility became fully operational during the second half of
2012. Late in the fourth quarter of 2015, AMAK temporarily closed the operation to preserve the assets in the ground while initiating steps
to  improve  efficiencies  and  optimize  operations.  The  plant  resumed  operation  in  the  fourth  quarter  of  2016  and  operating  rates,  metal
recoveries and concentrate quality has continued to improve throughout 2017 and 2018.

AMAK  shipped  approximately  58,000,  28,000,  and  16,000  metric  tons  of  copper  and  zinc  concentrate  to  outside  smelters  during  2018,
2017, and 2016, respectively. In 2014 AMAK initiated operation of its precious metal recovery circuit at the mill and produced gold and
silver  doré  intermittently  through  2014  and  2015.  The  precious  metals  circuit  was  recommissioned  in  the  fourth  quarter  of  2017  and
produced commercial quantities of gold and silver bearing doré in 2018.

Saudi Industrial Development Fund ("SIDF") Loan and Guarantee

On October 24, 2010, we executed a limited guarantee in favor of the SIDF guaranteeing up to 41% of the SIDF loan to AMAK in the
principal amount of 330,000,000 Saudi Riyals (US$88,000,000) (the "Loan"). As a condition of the Loan, SIDF required all shareholders of
AMAK to execute personal or corporate guarantees totaling 162.55% of the overall Loan amount. As ownership percentages have changed
over time, the loan guarantee allocation has not changed. The other AMAK shareholders provided personal guarantees. We were the only
AMAK shareholder providing a corporate guarantee. The loan was required in order for AMAK to fund construction of the underground
and  above-ground  portions  of  its  mining  project  in  southwest  Saudi  Arabia  and  to  provide  working  capital  for  commencement  of

Accounting Treatment of Investment in AMAK.

We have significant influence over the operating and financial policies of AMAK and therefore, account for it using the equity method. We
have one representative on the Executive Committee of the Board of Directors of AMAK. We also have one director who serves as Chair
on the Commercial Committee of AMAK. AMAK is effectively self-operating under a new, experienced management team. See Note 10 to
the Notes to the Consolidated Financial Statements.

We assess our investment in AMAK for impairment when events are identified, or there are changes in circumstances that indicate that the
carrying amount of the investment might not be recoverable. We consider recoverable ore reserves, mineral prices,

7

Table of Contents

operational costs, and the amount and timing of the cash flows to be generated by the production of those reserves, as well as recent equity
transactions within AMAK.

Item 1A.   Risk Factors.

We  are  subject  to  a  variety  of  risks  inherent  in  the  global  specialty  petrochemical,  specialty  wax  and  mining  (due  to  our  investment  in
AMAK) businesses. Many of these risk factors are not within our control and could adversely affect our business, results of operations or
our financial condition.

We  rely  on  a  limited  number  of  customers,  including  one  customer  that  represented  more  than  10%  of  our  consolidated  revenue  in
2018.  A  significant  change  in  customer  relationships  or  in  customer  demand  for  our  products  could  materially  adversely  affect  our
results of operations, financial position and cash flows.

We rely on a limited number of customers. Our largest customer, ExxonMobil and its affiliates, represented approximately 17.0% of our
consolidated  revenues  in  2018. A  significant  reduction  in  sales  to  any  of  our  other  key  customers  could  materially  adversely  affect  our
results of operations, financial position and cash flows, and could result from our key customers further diversifying their product sourcing,
experiencing financial difficulty or undergoing consolidation.

Our  industry  is  highly  competitive,  and  we  may  lose  market  share  to  other  producers  of  specialty  petrochemicals,  specialty  waxes  or
other  products  that  can  be  substituted  for  our  products,  which  may  adversely  affect  our  results  of  operations,  financial  position  and
cash flows.

Our industry is highly competitive, and we face significant competition from both large international producers and from smaller regional
competitors.  Our  competitors  may  improve  their  competitive  position  in  our  core  markets  by  successfully  introducing  new  products,
improving their manufacturing processes or expanding their capacity or manufacturing facilities. Further, some of our competitors benefit
from advantageous cost positions that could make it increasingly difficult for us to compete in certain markets. If we are unable to keep
pace with our competitors' product and manufacturing process innovations, cost position or alternative value proposition, it could have a
material adverse effect on our results of operations, financial condition and cash flows.

In  addition,  we  face  increased  competition  from  companies  that  may  have  greater  financial  resources  and  different  cost  structures,
alternative values or strategic goals than us. We have a portfolio of businesses across which we must allocate our available resources, while
competing companies may specialize in only certain of our product lines. As a result, we may invest less in certain areas of our business
than  our  competitors,  and  such  competitors  may  have  greater  financial,  technical  and  marketing  resources  available  to  them.  Industry
consolidation  may  also  affect  competition  by  creating  larger,  more  homogeneous  and  stronger  competitors  in  the  markets  in  which  we
compete,  and  competitors  also  may  affect  our  business  by  entering  into  exclusive  arrangements  with  existing  or  potential  customers  or
suppliers.  We  may  have  to  lower  the  prices  of  many  of  our  products  and  services  to  stay  competitive,  while  at  the  same  time,  trying  to
maintain or improve revenue and gross margin.

Loss of key employees, our inability to attract and retain new qualified employees or our inability to keep our employees focused on our
strategies and goals could have an adverse impact on our operations.

In order to be successful, we must attract, retain and motivate executives and other key employees including those in managerial, technical,
safety, sales and marketing positions. We must also keep employees focused on our strategies and goals. The failure to hire, or loss of, key
employees in a competitive industry could have a significant adverse impact on our operations. In addition, an important component of our
competitive  performance  is  our  ability  to  operate  safely  and  efficiently,  including  our  ability  to  manage  expenses  and  minimize  the
production  of  low  margin  products  on  an  on-going  basis.  This  requires  continuous  management  focus,  including  technological
improvements, safe operations, cost control and productivity enhancements. The extent to which we manage these factors will impact our
performance relative to competition.

We do not control the activities of AMAK and are dependent on AMAK's management and board of directors.

Although we believe that we have influence over the operating and financial policies of AMAK, we do not control AMAK's activities. The
extent to which we are able to influence specific operating and financial decisions depends on our ability to persuade other AMAK board
members  and  management  regarding  these  policies.  Our  ability  to  persuade  them  may  be  adversely  affected  by  cultural  differences,
differing  accounting  and  management  practices  and  differing  governmental  laws  and  regulations.  In  addition,  we  rely  upon  AMAK's
management and board of directors to direct the operations of AMAK, including employing various engineering and financial advisors to
assist in the development and evaluation of the mining projects in Saudi Arabia. We also rely on management of AMAK to provide timely,
accurate financial information required for inclusion with our reports filed with the SEC.

There can be no assurance that our investment in AMAK will not be negatively impacted by the decisions made by AMAK's management
and  board  of  directors  regarding  AMAK's  activities,  including  with  respect  to  the  selection  and  use  of  consultants  and  experienced
personnel to manage the operation in Saudi Arabia.

Maintenance, expansion and refurbishment of our facilities and the development and implementation of new manufacturing processes
involve significant risks which may adversely affect our business, results of operations, financial condition and cash flows.

Our  facilities  require  periodic  maintenance,  upgrading,  expansion,  refurbishment  or  improvement.  Any  unexpected  operational  or
mechanical failure, including failure associated with breakdowns and forced outages, could reduce our facilities' production capacity below
expected  levels  which  would  reduce  our  revenues  and  profitability.  Unanticipated  expenditures  associated  with  maintaining,  upgrading,
expanding, refurbishing or improving our facilities may also reduce profitability.

If we make any major modifications to our facilities, such modifications likely would result in substantial additional capital expenditures
and may prolong the time necessary to bring the facility on line. We may also choose to refurbish or upgrade our facilities based on our
assessment  that  such  activity  will  provide  adequate  financial  returns.  However,  such  activities  require  time  for  development  before
commencement of commercial operations, and key assumptions underpinning a decision to make such an investment may prove incorrect,
including assumptions regarding construction costs, demand growth and timing which could have a material adverse effect on our business,
results of operations, financial condition and cash flows.

Finally, we may not be successful or efficient in developing or implementing new production processes. Innovation in production processes
involves  significant  expense  and  carries  inherent  risks,  including  difficulties  in  designing  and  developing  new  process  technologies,
development and production timing delays, lower than anticipated manufacturing yields, and product defects. Disruptions in the production
process can also result from errors, defects in materials, delays in obtaining or revising operating permits and licenses, returns of product
from customers, interruption in our supply of materials or resources and disruptions at our facilities due to accidents, maintenance issues, or
unsafe  working  conditions,  all  of  which  could  affect  the  timing  of  production  ramps  and  yields.  Production  issues  can  lead  to  increased
costs  and  may  affect  our  ability  to  meet  product  demand,  which  could  adversely  impact  our  business,  results  of  operations,  financial
condition and cash flows.

The covenants in the instruments that govern our outstanding indebtedness may limit our operating and financial flexibility.

In addition, the ARC Agreement also has financial covenants that require TOCCO to maintain a maximum Consolidated Leverage Ratio
and  minimum  Consolidated  Fixed  Charge  Coverage  Ratio  (each  as  defined  in  the ARC Agreement).  See  Part  II,  Item  7.  Management's
Discussion and Analysis of Financial Condition and Results of Operations-Liquidity and Capital Resources-Credit Agreement.

A failure by us or our subsidiaries to comply with the covenants and restrictions contained in the agreements governing our indebtedness
could result in an event of default under such indebtedness, which could adversely affect our ability to respond to changes in our business
and manage our operations. Upon the occurrence of an event of default under any of the agreements

9

 
Table of Contents

governing our indebtedness, the lenders could elect to declare all amounts outstanding to be due and payable and exercise other remedies as
set forth in the agreements. Further, an event of default or acceleration of indebtedness under one instrument may constitute an event of
default  under  another  instrument.  If  any  of  our  indebtedness  were  to  be  accelerated,  there  can  be  no  assurance  that  our  assets  would  be
sufficient  to  repay  this  indebtedness  in  full,  which  could  have  a  material  adverse  effect  on  our  ability  to  continue  to  operate  as  a  going
concern.

Our substantial indebtedness could limit cash flow available for our operations and could adversely affect our ability to service debt or
obtain additional financing if necessary.

As of December 31, 2018, we had $18 million in borrowings outstanding under our revolving credit facility (the "Revolving Facility") and
$84.5 million in borrowings outstanding under our term loan facility (the "Term Loan Facility" and, together with the Revolving Facility,
the  "Credit  Facilities").  Pursuant  to  the  terms  of  the  amended  and  restated  credit  agreement  (as  amended  to  the  date  hereof,  the  "ARC
Agreement")  governing  the  Credit  Facilities,  we  also  have  the  option,  at  any  time,  to  request  an  increase  to  the  commitment  under  the
Revolving  Facility  and/or  the  Term  Loan  Facility  by  an  additional  amount  of  up  to  $50.0  million  in  the  aggregate,  subject  to  lenders
acceptance of the increased commitment and other conditions.

Although  the  agreements  governing  our  existing  indebtedness  contain  restrictions  on  the  incurrence  of  additional  indebtedness,  these
restrictions are subject to a number of important exceptions, and additional indebtedness that we may incur from time to time to finance
projects or for other reasons in compliance with these restrictions could be substantial. If we incur significant additional indebtedness, the
related risks that we face could increase.

Our current, or any future, indebtedness could:

•

•

•

•

•

limit  our  flexibility  in  planning  for,  or  reacting  to,  changes  in  the  markets  in  which  we
compete;

place  us  at  a  competitive  disadvantage  relative  to  our  competitors  with  less
indebtedness;

limit  our  ability

render  us  more  vulnerable  to  general  adverse  economic,  regulatory  and  industry  conditions;
and

require  us  to  dedicate  a  substantial  portion  of  our  cash  flow  to  service  our
indebtedness.

Our ability to meet our cash requirements, including our debt service obligations, is dependent upon our ability to maintain our operating
performance, which will be subject to general economic and competitive conditions and to financial, business and other factors, many of
which are beyond our control. We cannot provide assurance that our business will generate sufficient cash flow from operations to fund our
cash requirements and debt service obligations.

Conditions in the global economy may adversely affect our results of operations, financial condition and cash flows.

The  demand  for  our  products  have  historically  correlated  closely  with  general  economic  growth  rates.  The  occurrence  of  recessions  or
other periods of low or negative growth will typically have a direct adverse impact on our results of operations, financial condition and cash
flows. Other factors that affect general economic conditions in the world or in a major region, such as changes in population growth rates or
periods of civil unrest, also impact the demand for our products. Economic conditions that impair the functioning of financial markets and
financial  institutions  also  pose  risks  to  us,  including  risks  to  the  safety  of  our  financial  assets  and  to  the  ability  of  our  partners  and
customers to fulfill their commitments to us.

In addition, the revenue and profitability of our operations have historically been subject to fluctuation, which makes future financial results
less predictable. Our revenue, gross margin and profit vary among our products, customer groups and geographic markets. Overall gross
margins and profitability in any given period are dependent partially on the product, customer and geographic mix reflected in that period's
net  revenue.  In  addition,  newer  geographic  markets  may  be  relatively  less  profitable  due  to  investments  associated  with  entering  those
markets and local pricing pressures. Market trends, competitive pressures, increased raw material or shipping costs, regulatory impacts and
other factors may result in reductions in revenue or pressure on gross margins of certain segments in a given period which may necessitate
adjustments to our operations.

To  service  our  current,  and  any  future,  indebtedness,  we  will  require  a  significant  amount  of  cash,  which  may  adversely  affect  our
future results.

Our ability to generate cash depends on many factors beyond our control, and any failure to meet our debt service obligations

10

Table of Contents

could harm our business, results of operations and financial condition. Our ability to make payments on and to refinance our indebtedness,
and to fund working capital needs and planned capital expenditures, will depend on our ability to generate cash in the future. This, to a
certain extent, is subject to general economic, financial, competitive, business, legislative, regulatory and other factors that are beyond our
control.

If our business does not generate sufficient cash flow from operations or if future borrowings are not available to us in an amount sufficient
to enable us to pay our indebtedness, or to fund our other liquidity needs, we may need to refinance all or a portion of our indebtedness (or
otherwise  seek  amendment  or  relief  from  the  terms  of  our  indebtedness),  on  or  before  the  maturity  thereof,  sell  assets,  reduce  or  delay
capital investments or seek to raise additional capital, any of which could have a material adverse effect on our operations. We might not
generate sufficient cash flow to repay indebtedness as currently anticipated. In addition, we may not be able to effect any of these actions, if
necessary, on commercially reasonable terms or at all. Our ability to restructure or refinance our indebtedness, will depend on the condition
of the capital markets and our financial condition at such time. Any refinancing of our indebtedness could be at higher interest rates and
may  require  us  to  comply  with  more  onerous  covenants,  which  could  further  restrict  our  business  operations.  The  terms  of  existing  or
future debt instruments may limit or prevent us from taking any of these actions. Our inability to generate sufficient cash flow to satisfy our
debt service obligations, or to refinance or restructure our obligations on commercially reasonable terms or at all, would have a material
adverse effect on our business, results of operations and financial conditions.

There are certain hazards and risks inherent in our operations that could adversely affect those operations and results of operations
and financial condition.

As  a  manufacturer  and  distributor  of  diversified  chemical  products,  our  business  is  subject  to  operating  risks  inherent  in  chemical
manufacturing, storage, handling and transportation. These risks include, but are not limited to, fires, explosions, severe weather and natural
disasters,  mechanical  failure,  unscheduled  downtime,  loss  of  raw  materials  or  our  products,  transportation  interruptions,  remediation,
chemical spills, terrorist acts or war, discharges or releases of toxic or hazardous substances or gases. These hazards can cause personal
injury  and  loss  of  life,  severe  damage  to,  or  destruction  of,  property  and  equipment  and  environmental  contamination.  In  addition,  our
suppliers are also subject to similar risks that may adversely impact our production capabilities. A significant limitation on our ability to
manufacture products due to disruption of manufacturing operations or related infrastructure could have a material adverse effect on our
results of operations and financial condition.

While  we  adapt  our  manufacturing  and  distribution  processes  and  controls  to  minimize  the  inherent  risk  of  our  operations,  to  promote
workplace safety and to minimize the potential for human error, we cannot completely eliminate the risk of accidental contamination or
injury from hazardous or regulated materials, including injury of our employees, individuals who handle our products or goods treated with
our products, or others who claim to have been exposed to our products, nor can we completely eliminate the unanticipated interruption or
suspension  of  operations  at  our  facilities  due  to  such  events.  We  may  be  held  liable  for  significant  damages  or  fines  in  the  event  of
contamination or injury, and such assessed damages or fines could have a material adverse effect on our results of operations and financial
conditions. Our property, business interruption and casualty insurance may not fully insure us against all potential hazards incidental to our
business.

Increases in the costs of our raw materials could have an adverse effect on our financial condition and results of operations if those
costs cannot be passed onto our customers.

Our  results  of  operations  are  directly  affected  by  the  cost  of  raw  materials.  Since  the  cost  of  these  primary  raw  materials  comprise  a
significant  amount  of  our  total  cost  of  goods  sold,  the  selling  prices  for  our  products  and  therefore  our  total  revenue  is  impacted  by
movements in these raw material costs, as well as the cost of other inputs. In the past we have experienced erratic and significant changes
in the costs of these raw materials, the cost of which has generally correlated with changes in energy prices, supply and demand factors,
and prices for natural gas and crude oil. In addition, product mix can have an impact on our overall unit selling prices, since we provide an
extensive product offering and therefore experience a wide range of unit selling prices. Because of the significant portion of our cost of
goods sold represented by these raw materials, our gross profit margins could be adversely affected by changes in the cost of these raw
materials if we are unable to pass the increases on to our customers.

Due to volatile raw material prices, there can be no assurance that we can continue to recover raw material costs or retain customers in the
future.  For  example,  our  logistics  costs  have  increased  substantially  within  the  past  three  years,  narrowing  our  profit  margins.  This  may
force us to increase our pricing, which could cause customers to consider competitors' products, some of which may be available at a lower
cost. Significant loss of customers could result in a material adverse effect on our results of operations, financial condition and cash flows.

11

Table of Contents

If the availability of our raw materials is limited, we may be unable to produce some of our products in quantities sufficient to meet
customer demand or on favorable economic terms, which could have an adverse effect on our results of operations, financial condition
and cash flows.

We use polyethylene waxes in our specialty synthetic wax segment and use additional non-primary raw materials in the production of our
products  in  the  specialty  petrochemical  segment  and  synthetic  wax  segment.  Suppliers  may  not  be  able  to  meet  our  raw  material
requirements and we may not be able to obtain substitute supplies from alternative suppliers in sufficient quantities, on economic terms, or
in a timely manner. A lack of timely availability of our raw materials in the quantities we require to produce our products could result in
our inability to meet customer demand and could have a material adverse effect on our results of operations, financial condition and cash
flows.

Certain activist stockholders actions could cause us to incur expense and hinder execution of our strategy.

While we seek to actively engage with our stockholders and consider their views on business and strategy, we could be subject to actions or
proposals from our stockholders that do not align with our business strategies or the interests of our other stockholders. Responding to these
stockholders  could  be  costly  and  time-consuming,  disrupt  our  business  and  operations  and  divert  the  attention  of  our  management.
Furthermore, uncertainties associated with such activities could negatively impact our ability to execute our strategic plan, retain customers
and skilled employees and affect long-term growth. In addition, such activities may cause our stock price to fluctuate based on temporary or
speculative market perceptions that do not necessarily reflect our business operations.

We  expect  to  continue  to  incur  capital  expenditures  and  operating  costs  as  a  result  of  our  compliance  with  existing  and  future
environmental laws and regulations.

Our industry is subject to extensive laws and regulations related to the protection of the environment. These laws and regulations continue
to increase in both number and complexity and affect our operations with respect to, among other things: the discharge of pollutants into the
environment; emissions into the atmosphere (including greenhouse gas emissions); and restrictions, liabilities and obligations in connection
with  storage,  transportation,  treatment  and  disposal  of  hazardous  substances  and  waste.  We  are  also  subject  to  laws  and  regulations  that
require us to operate and maintain our facilities to the satisfaction of applicable regulatory authorities. In addition, failure to comply with
these laws or regulations, or failure to obtain required permits from applicable regulatory authorities, may expose us to fines, penalties or
interruptions  in  operations.  To  the  extent  these  capital  expenditures  or  operating  costs  are  not  ultimately  reflected  in  the  prices  of  our
products and services, or that we are subject to fines, penalties or other interruptions in our operations, our business, results of operations,
financial position and cash flows may be adversely affected.

If  we  are  unable  to  access  third-party  transportation  for  our  raw  materials  and  finished  products,  we  may  not  be  able  to  fulfill  our
obligations  to  our  customers  in  a  timely  manner,  which  could  have  a  material  adverse  effect  on  our  results  of  operations,  financial
condition and cash flows.

We  rely  upon  transportation  provided  by  third  parties  (including  common  carriers,  rail  companies  and  trans-ocean  cargo  companies)  to
receive raw materials used in the production of our products and to deliver finished products to our customers. While we attempt to offset
the risks associated with third-party transportation issues, including by managing our supplies of raw materials, such mitigation efforts may
not  be  successful.  If  we  are  unable  to  access  third-party  transportation  at  economically  attractive  rates,  or  at  all,  or  if  there  is  any  other
significant disruption in the availability of third-party transportation, we may not be able to obtain sufficient quantities of raw materials (on
favorable terms, or at all) to match the pace of production and/or we may not be able to fulfill our obligations to our customers in a timely
manner, which could have a material adverse effect on our results of operations, financial condition and cash flows.

If we are not able to continue the technological innovation and successful commercial introduction of new products, our customers may
turn to other producers to meet their requirements, which may adversely affect our results of operations, financial position and cash
flows.

Our  industry  and  the  markets  into  which  we  sell  our  products  experience  periodic  technological  change  and  ongoing  product
improvements.  In  addition,  our  customers  may  introduce  new  generations  of  their  own  products,  adopt  new  or  different  risk  profiles,  or
require  new  technological  and  increased  performance  specifications  that  would  require  us  to  develop  customized  products.  Our  future
growth  and  profitability  will  depend  on  our  ability  to  maintain  or  enhance  technological  capabilities,  develop  and  market  products  and
applications that meet changing customer requirements and successfully anticipate or respond to technological changes in a cost effective
and timely manner. Our inability to maintain a technological edge, innovate and improve our products could cause a decline in the demand
and sales of our products and adversely affect our results of operations, financial position and cash flows.

We are subject to numerous regulations that could require us to modify our current business practices and incur increased costs.

We  are  subject  to  numerous  regulations,  including  customs  and  international  trade  laws,  export  control,  data  privacy,  antitrust  laws  and
zoning and occupancy laws that regulate manufacturers generally and/or govern the importation, promotion and sale of our products, the
operation of our facilities and our relationship with our customers, suppliers and competitors. In addition, we face risk associated with trade
protection laws, policies and measures and other regulatory requirements affecting trade and investment, including loss or modification of
exemptions  for  taxes  and  tariffs,  imposition  of  new  tariffs  and  duties  and  import  and  export  licensing  requirements.  If  these  laws  or
regulations were to change or were violated by our management, employees, suppliers, buying agents or trading companies, the costs of
certain  goods  could  increase,  or  we  could  experience  delays  in  shipments  of  our  goods,  be  subject  to  fines  or  penalties,  or  suffer
reputational harm, which could reduce demand for our products and hurt our business and negatively impact our results of operations. In
addition, changes in federal and state minimum wage laws and other laws relating to employee benefits could cause us to incur additional
wage and benefits costs, which could negatively impact our profitability.

Legal requirements are frequently changed and subject to interpretation, and we are unable to predict the ultimate cost of compliance with
these  requirements  or  their  effects  on  our  operations.  We  may  be  required  to  make  significant  expenditures  or  modify  our  business
practices to comply with existing or future laws and regulations, which may increase our costs and materially limit our ability to operate our
business.

Failure  to  successfully  consummate  extraordinary  transactions,  including  the  integration  of  other  businesses,  assets,  products  or
technologies, or realize the financial and strategic goals that were contemplated at the time of any such transaction may adversely affect
our future business, results of operations and financial condition.

As  part  of  our  business  strategy,  we  from  time  to  time  explore  possible  investments,  acquisitions,  strategic  alliances,  joint  ventures,
divestitures and outsourcing transactions (collectively, "extraordinary transactions") in order to further our business objectives. To pursue
this strategy successfully, we must identify suitable candidates for, and successfully complete, extraordinary transactions, some of which
may be large and complex, and manage post-closing issues such as the integration of acquired businesses or employees. The expense and
effort  incurred  in  exploring  and  consummating  extraordinary  transactions,  the  time  it  takes  to  integrate  an  acquisition  or  our  failure  to
integrate  businesses  successfully,  could  result  in  additional  and/or  unexpected  expenses  and  losses.  We  also  may  not  be  successful  in
negotiating the terms of any potential extraordinary transactions, conducting thorough due diligence, financing an extraordinary transaction
or effectively integrating the acquired business, product or technology into our existing business and operations. Our due diligence may fail
to identify all of the problems, liabilities or other shortcomings or challenges of an acquired business, product or technology. Moreover, we
may incur significant expenses whether or not a contemplated extraordinary transaction is ultimately consummated.

Additionally, in connection with any extraordinary transaction we consummate, we many not fully realize all of the anticipated synergies
and  other  benefits  we  expect  to  achieve  (on  our  expected  timeframe,  or  at  all),  and  we  may  incur  unanticipated  expenses,  write-downs,
impairment charges or unforeseen liabilities that could negatively affect our business, financial condition and results of operations, disrupt
relationships  with  current  and  new  employees,  customers  and  vendors,  incur  significant  debt  or  have  to  delay  or  not  proceed  with
announced  transactions.  Further,  managing  extraordinary  transactions  requires  varying  levels  of  management  and  employee  resources,
which may divert our attention from other business operations.

The adoption of climate change legislation or regulation could result in increased operating costs and reduced demand for our products.

The nature of our operations could make us subject to legislation or regulations affecting the emission of greenhouse gases. The U.S.
Environmental Protection Agency has promulgated (and may in the future promulgate) regulations applicable to projects involving
greenhouse gas emissions above a certain threshold, and the U.S. and certain states within the U.S. have enacted, or are considering,
limitations on greenhouse gas emissions. Jurisdictions outside the U.S. are also addressing greenhouse gases by legislation or regulation. In
addition, efforts have been made and continue to be made at the international level toward the adoption of international treaties or protocols
that would address global greenhouse gas emissions. These limitations may include the adoption of cap and trade regimes, carbon taxes,
restrictive permitting, increased efficiency standards and incentives or mandates for renewable energy. Any such requirements could make
our products more expensive, lengthen project implementation times and reduce demand for hydrocarbons, as well as shift hydrocarbon
demand toward relatively lower-carbon sources. Such legislation, regulation, treaties or protocols may also increase our compliance costs,
such as for monitoring or sequestering emissions.

Adverse results of legal proceedings could materially adversely affect us.

We are subject to and may in the future be subject to a variety of legal proceedings and claims that arise out of the ordinary conduct of our
business,  including  legal  proceedings  brought  in  non-U.S.  jurisdictions.  Results  of  legal  proceedings  cannot  be  predicted  with  certainty.
Irrespective  of  its  merits,  litigation  may  be  both  lengthy  and  disruptive  to  our  operations  and  may  cause  significant  expenditure  and
diversion of management attention. We may be faced with significant monetary damages or injunctive relief against us that could have an
adverse impact on our business and results of operations should we fail to prevail in certain matters.

Cost pressures could negatively impact AMAK's operating margins and expansion plans.

Cost  pressures  may  continue  to  occur  across  the  resources  industry. As  the  prices  for AMAK's  products  are  determined  by  the  global
commodity markets in which it operates, AMAK does not generally have the ability to offset these cost pressures through corresponding
price increases, which can adversely affect its operating margins or require changes in operations, including, but not limited to, temporary
planned shutdowns. Notwithstanding AMAK's efforts to reduce costs, and a number of key cost inputs being commodity price-linked, the
inability to reduce costs and a timing lag may adversely impact AMAK's operating margins for an extended period.

An impairment of goodwill could negatively impact our results of operations.

At least annually, we assess goodwill for impairment. If an initial qualitative assessment identifies that it is more likely than not that the
carrying value of a reporting unit exceeds its estimated fair value, additional quantitative testing is performed. We may also elect to skip
the  qualitative  testing  and  proceed  directly  to  quantitative  testing.  If  the  quantitative  testing  indicates  that  goodwill  is  impaired,  the
carrying  value  of  goodwill  is  written  down  to  fair  value  with  a  charge  against  earnings.  Since  we  utilize  a  discounted  cash  flow
methodology to calculate the fair value of our operating units, continued weak demand for a specific product line or business could result in
an impairment charge. Accordingly, any determination requiring the write-off of a significant portion of goodwill could negatively impact
our results of operations.

Our variable rate indebtedness subjects us to interest rate risk, which could cause our debt service obligations to increase significantly.

Borrowings under the Credit Facilities are, and additional borrowings in the future may be, at variable rates of interest that expose us to
interest  rate  risk.  If  interest  rates  increase,  our  debt  service  obligations  on  the  variable  rate  indebtedness  will  increase  even  though  the
amount borrowed will remain the same, and our net income and cash flows, including cash available for servicing our indebtedness, will
correspondingly decrease. We may in the future enter into, interest rate swaps for our variable rate debt whereby we exchange floating for
fixed rate interest payments in order to reduce exposure to interest rate volatility. However, any interest rate swaps into which we enter may
not fully mitigate our interest rate risk.

We are exposed to local business risks in different countries, which could have a material adverse effect on our financial condition and
results of operations.

Although we do not have production operations and assets outside of the U.S., we do have a global portfolio of customers and thus we are
subject to a variety of international market risks including, but not limited to:

•

•

•

•

•

•

•

•

•

•

ongoing instability or changes in a country's or region's economic or political conditions,  including  inflation,  recession,  interest  rate
fluctuations, civil unrest and actual or anticipated military or political conflicts (including the potential impact of continued hostilities
and conflict in Yemen on the operations of AMAK);
longer  accounts  receivable  cycles  and  financial  instability  or  credit  risk  among  customers  and
distributors;
trade regulations and procedures and actions affecting production, pricing and marketing of products, including domestic and foreign
customs and tariffs or other trade barriers;
regulations  favoring  local  contractors  or  requiring  foreign  contractors  to  employ  citizens  of,  or  purchase  supplies  from,  a  local
jurisdiction;
local  labor  conditions  and  regulations  and  the  geographical  dispersion  of  the
workforce;
changes

environment;
differing 
requirements;

affect our ability to obtain favorable terms for labor and raw materials or lead to penalties or restrictions;

restrictions 

and

Such economic and political uncertainties may materially and adversely affect our business, financial condition or results of operations in
ways that cannot be predicted at this time. Although it is impossible to predict the occurrences or consequences of any such events, they
could result in a decrease in demand for our products, make it difficult or impossible to deliver products to our customers or to receive raw
materials from our suppliers and create delays and inefficiencies in our supply chain. We are also predominantly uninsured for losses and
interruptions caused by terrorist acts, conflicts and wars.

We may have additional tax liabilities, which may adversely affect our financial position.

We are subject to income taxes and state taxes in the U.S. Significant judgment is required in determining our provision for income taxes.
In  the  ordinary  course  of  our  business,  there  are  many  transactions  and  calculations  where  the  ultimate  tax  determination  is  uncertain.
Although we believe our tax estimates are reasonable, the final determination of tax audits and any related litigation could be materially
different  to  that  which  is  reflected  in  our  consolidated  financial  statements.  Should  any  tax  authority  take  issue  with  our  estimates,  our
results of operations, financial position and cash flows could be adversely affected.

The U.S. Tax Cuts and Jobs Act ("TCJA") was enacted on December 22, 2017, and introduces significant changes to U.S. income tax law.
Accounting Standards Codification 740, Accounting for Income Taxes, requires companies to recognize the effects of tax law changes in
the period of enactment. Effective in 2018, the TCJA made a number changes, such as reducing the U.S. statutory tax rate from 35% to
21%,  creating  new  taxes  on  certain  foreign  sourced  earnings  and  certain  related-party  payments,  which  are  referred  to  as  the  global
intangible low taxed income tax and the base erosion tax, respectively, establishing a dividends received deduction for dividends paid by
foreign  subsidiaries  to  the  U.S.,  the  elimination  or  limitation  of  certain  deductions,  and  imposing  a  mandatory  tax  on  previously
unrepatriated  earnings  accumulated  offshore.  Due  to  the  timing  of  the  new  tax  law  provided  in  the  TCJA  and  the  substantial  changes  it
brings, the Staff of the SEC issued Staff Accounting Bulletin No. 118, which provides registrants with a measurement period to report the
impact  of  the  new  US  tax  law. As  a  result,  the  recorded  and  estimated  impacts  of  the  TCJA  may  change  in  future  periods,  which  may
adversely affect our estimates, our results of operations, financial position and cash flows.

AMAK is also subject to various taxes in Saudi Arabia. While AMAK currently benefits from certain tax credits that reduce its overall tax
liability,  there  can  be  no  assurance  that  relevant  tax  authorities  will  continue  to  maintain  such  credits.  In  addition,  there  can  be  no
assurances  that  future  changes  in  tax  law  in  Saudi Arabia  will  not  result  in  increased  tax  liability  to AMAK. A  material  increase  in  tax
liability could have an adverse effect on AMAK's results of operations and financial condition, which may in turn have an adverse effect on
our investment in AMAK.

We from time to time are subject to contingent liabilities. If any contingent liabilities become actual liabilities, our financial condition
may be adversely affected.

We are subject to various contingent liabilities that may affect our liquidity and our ability to meet our obligations, including our limited
corporate  guarantee  to  SIDF  in  connection  with AMAK's  Loan  to  fund  mining  operations.  To  the  extent  any  of  our  current  or  future
contingent liabilities become actual liabilities, it may have an adverse effect on our financial condition.

We may be unable to recover our investment in AMAK, which could adversely affect our results of operations and financial condition.

We will only recover our investment in AMAK through the receipt of distributions or future share repurchases from AMAK or the sale of
part or all of our interest in AMAK. If AMAK does not continue to be profitable, our ability to recover our investment will be adversely
affected. Moreover, if AMAK continues to be profitable, there can be no assurance that the board of directors of AMAK will determine
that  it  is  in  the  best  interests  of  AMAK  and  its  shareholders  to  make  distributions  to  its  shareholders  or  to  initiate  additional  share
repurchases. In addition, we understand that AMAK is required to sell a portion of its equity to the public once AMAK has been profitable
for two years. While the proceeds of such a sale might allow us to recover our investment in AMAK, there is no assurance that the market
conditions  for  any  such  public  sale  will  be  favorable  enough  to  allow  us  to  recover  our  investment  or  that  some  or  all  of  our  shares  in
AMAK will be include in any such sale. To the extent we are unable to recover our investments in AMAK, our results of operations and
financial condition may be adversely affected.

AMAK may have fewer mineral reserves than its estimates indicate.

Fluctuations  in  the  price  of  commodities,  variation  in  production  costs  or  different  recovery  rates  could  result  in  AMAK's  estimated
reserves being revised in the future. If such a revision were to indicate a substantial reduction in proven or probable reserves at one or more
of AMAK's projects, it could adversely affect our investment in AMAK.

Domestic or international terrorist attacks may disrupt our operations or otherwise have an adverse impact on our business.

It  is  possible  that  further  acts  of  terrorism  may  be  directed  against  the  U.S.  domestically  or  abroad,  and  such  acts  of  terrorism  could  be
directed  against  our  investment  in  those  locations.  Moreover,  chemical  related  assets,  and  U.S.  corporations  such  as  ours,  may  be  at  a
greater  risk  of  future  terrorist  attacks  than  other  possible  targets.  The  resulting  damage  from  such  an  event  could  include  loss  of  life,
property damage or site closure. Any, or a combination, of these factors could adversely impact our results of operations, financial position
and cash flows.

Increased information systems security threats and more sophisticated and targeted computer crime could pose a risk to our systems,
networks, products and services.

Increased information systems security threats and more sophisticated, targeted computer crime pose a risk to the security of our systems
and networks and the confidentiality, availability, and integrity of our data, operations, and communications. While we attempt to mitigate
these  risks  by  employing  a  number  of  measures,  including  security  measures,  employee  training,  comprehensive  monitoring  of  our
networks  and  systems,  and  maintenance  of  backup  and  protective  systems,  if  these  measures  prove  inadequate,  we  could  be  adversely
affected by, among other things, loss or damage of intellectual property, proprietary and confidential information, and communications or
customer  data,  having  our  business  operations  interrupted  and  increased  costs  to  prevent,  respond  to,  or  mitigate  these  cyber  security
threats. Any significant disruption or slowdown of our systems could cause customers to cancel orders or standard business processes to
become inefficient or ineffective, which could adversely affect our results of operations, financial position and cash flows.  

Implementation  of  changes  to  our  enterprise  resource  planning  ("ERP")  system  may  adversely  affect  our  business  and  results  of
operations or the effectiveness of internal controls over financial reporting.

During 2017, we implemented a new ERP system at our specialty petrochemical facility in order to better manage our business, and we
continue to implement additional improvements to the system. ERP implementations are complex and time-consuming projects that involve
substantial expenditures on system software and implementation activities over a significant period of time. If we do not effectively
implement changes to ERP system, or if the system does not operate as intended, it could adversely affect our financial reporting systems
and our ability to produce financial reports, the effectiveness of internal controls over financial reporting (including our disclosure controls
and procedures), and our business and results of operations.

United States Specialty Petrochemical Facility

SHR owns and operates a specialty petrochemical facility near Silsbee, Texas which is approximately 30 miles north of Beaumont, Texas,
and 90 miles east of Houston. The facility consists of eight operating units which, while interconnected, make distinct products through
different  processes:  (i)  a  Penhex  Unit;  (ii)  a  Reformer;  (iii)  a  Cyclo-pentane  Unit;  (iv)  an Advanced  Reformer  unit;  (v)  an Aromatics
Hydrogenation Unit; (vi) a White Oil Fractionation Unit; (vii) a Hydrocarbon Processing Demonstration Unit, and (viii) a P-Xylene Unit.
All of these units are currently in operation. Our new 4,000 barrel per day Advanced Reformer unit successfully re-started in December
2018. This unit will provide security of hydrogen supply for Penhex and custom processing projects as well as increase the value of our by-
products.

GSPL owns and operates three 8-inch diameter pipelines and five 4-inch diameter pipelines aggregating approximately 70 miles in length
connecting SHR's facility to (1) a natural gas line, (2) SHR's truck and rail loading terminal and (3) a major petroleum products pipeline
system  owned  by  an  unaffiliated  third  party. All  pipelines  are  operated  within  Texas  Railroad  Commission  and  DOT  regulations  for
maintenance and integrity.

United States Specialty Polyethylene Wax Facility

TC owns and operates a specialty synthetic wax facility from its 27.5 acre plant site located in Pasadena, Texas. After the acquisition of the
adjacent BASF facility ("B Plant") in 2016 the plant contains several stainless steel reactors ranging in size from 3,300 to 16,000 gallons
with overhead condensing systems, two 4,000 gallon glass line reactors, five Sandvik forming belts with pastillating capabilities, five high
vacuum wiped film evaporators varying in size from 12 to 20 m2, steel batch column with 10,000 gallon still pot and 20 theoretical stages of
structured packing. This plant has the ability to crystallize and recover solids from the crystallization process.  There are also three fully
equipped  laboratories  onsite.  With  a  base  product  offering  of  polyethylene  waxes,  TC  is  well  suited  to  manage  high  molecular  weight
materials  that  must  be  managed  in  the  molten  state.  In  2017,  TC  expanded  its  processing  capabilities  with  the  start-up  of  the
hydrogenation/distillation  unit.  This  $25  million  investment  provides  TC's  customers  with  state-of-the-art  distillation  and  high-pressure
hydrogenation  capabilities.  During  2018,  TC  experienced  issues  with  the  reliable  operation  of  this  unit  in  accordance  with  its  design
specifications.  Efforts  are  underway  to  implement  design  corrections  and  fixes  to  improve  the  unit's  capability  and  reliability.  TC  offers
pastillating for waxes, polymers and resins, flaking capabilities, as well as solids packaging services.

Investment in AMAK

As of December 31, 2018, we owned a 33% interest in AMAK.

Prior  to  December  2008,  we  held  a  thirty  year  mining  lease  (which  commenced  on  May  22,  1993)  covering  an  approximate  44  square
kilometer area in Najran Province in southwestern Saudi Arabia. The lease carried an option to renew or extend the term of the lease for
additional  periods  not  to  exceed  twenty  years.  The  lease  and  other  related  assets  located  in  Saudi Arabia  were  contributed  to AMAK  in
December  2008.  The  above-ground  ore  processing  facility  became  fully  operational  during  the  second  half  of  2012.      Late  in  the  fourth
quarter of 2015 AMAK temporarily closed the operation to preserve the assets in the ground while initiating steps to improve efficiencies
and optimize operations. The facility resumed operation in the fourth quarter of 2016 and operating rates, metal recoveries and concentrate
quality continued to improve steadily throughout 2017 and 2018.

AMAK  shipped  approximately  58,000,  28,000,  and  51,000  metric  tons  of  copper  and  zinc  concentrate  to  outside  smelters  during  2018,
2017 and 2016, respectively. In 2014 AMAK initiated operation of its precious metal recovery circuit at the mill and produced gold and
silver doré intermittently through 2014 and 2015. The precious metals circuit was recommissioned in fourth quarter of 2017 and produced
commercial quantities of gold and silver bearing doré in 2018.

The facility includes an underground mine, ore-treatment plant and related infrastructures. The ore-treatment plant is comprised of primary
crushing,  ore  storage,  SAG  milling  and  pebble  crushing,  secondary  ball  milling,  pre-flotation,  copper  and  zinc  flotation,  concentrate
thickening,  tailings  filtration,  cyanide  leaching,  reagent  handling,  tailings  dam  and  utilities.  Related  infrastructure  includes  a  300  men
capacity camp for single status accommodation for expatriates and Saudi employees, an on-site medical facility, a service building for 300
employees, on-site diesel generation of 10 megawatts, potable water supply, sewage treatment plant and an assay laboratory. The facilities
at the Port of Jazan are comprised of unloading facilities, concentrate storage and reclamation and ship loading facilities.

Metal  price  assumptions  follow  SEC  guidance  not  to  exceed  a  three  year  trailing  average.  The  following  chart  illustrates  the  change  in

Three mineralized zones, the Saadah, Al Houra and Moyeath, were outlined by initial diamond drilling. Based on the original 1994 WGM
feasibility  study  as  updated  in  1996,  2005  and  2009  the  following  tables  set  forth  a  summary  of  the  diluted  recoverable,  proven  and

For purposes of calculating proven and probable mineralized materials, a dilution of 5% at zero grade on the Saadah zone and 15% at zero
grade on the Al Houra and Moyeath zones was assumed. A mining recovery of 80% was used for the Saadah zone and 88% for the Al
Houra and Moyeath zones. Mining dilution is the amount of wall-rock adjacent to the ore body that is included in the ore extraction process.
Base case cutoffs used were 5.0% zinc equivalent. Ore reserves were estimated using metal prices of USD $0.85 per pound for zinc, $2.50
per pound for copper, $800 per ounce for gold and $12.0 per ounce for silver.

Our rights to obtain additional mining licenses to other adjoining areas were also transferred to AMAK in December 2008 as part of our
initial  capital  contribution. AMAK  received  formal  approval  in  November  2015  of  an  additional  151  km 2  or  37,313  acres  of  territory
relatively close to the current mine. The new territory comprises the Guyan and Qatan exploration licenses covering 151 km2 and within
the Guyan exploration license, a 10 km2  or  2,471  acre  mining  lease  which  has  potential  for  significant  gold  recovery.  Some  exploration
holes were drilled in both Guyan and Qatan up to 40 years ago, but no reserves were attributed to these areas. Exploration activities were
restarted in both of these areas during 2016, and SRK Consulting prepared a JORC compliant report in May 2017 showing approximately
99,000 ounces at the Jebel Guyan zone excluding other nearby prospects. The diamond drilling program continues at both the Jebel Guyan
and Al Aqiq zones, testing depth and extension of mineralization with confirmed mineralization intersected at an additional 50 meters depth
the Guyan zone. A JORC compliant reserve update is currently being studied by Mining One (Australia).

Proven mineralized materials are those mineral deposits for which quantity is computed from dimensions revealed in outcrops, trenches,
workings or drill holes, and grade is computed from results of detailed sampling. For ore deposits to be proven, the sites for inspection,
sampling and measurement must be spaced so closely and the geologic character must be so well defined that the size, shape, depth and
mineral content of reserves are well established. Probable mineralized materials are those for which quantity and grade are computed from
information similar to that used for proven mineralized materials, but the sites for inspection, sampling

and measurement are farther apart or are otherwise less adequately spaced. However, the degree of assurance, although lower than that for
proven mineralized materials, must be high enough to assume continuity between points of observation.

The  metallurgical  studies  conducted  on  the  ore  samples  taken  from  the  zones  indicated  that  84.7%  of  the  copper  and  78.0%  of  the  zinc
could be recovered in copper and zinc concentrates. Overall, gold and silver recovery from the ore was estimated to be 77.3% and 81.3%,
respectively, partly into copper concentrate and partly as bullion through cyanide processing of zinc concentrates and mine tailings. Further
studies recommended by consultants may improve those recoveries and thus the potential profitability of the project; however, there can be
no assurances of this effect.

AMAK contracted with SRK Consulting for a reserves update in 2017 and SRK reported JORC compliant reserves in August 2017. The
SRK reserves estimate has since been updated by AMAK resource geologist (Qualified Person - QP as defined in JORC Code) in January
2018 and February 2019 with additional drill-hole data (85 holes and 8,970 meters in 2017 and 91 holes and 9,134 meters in 2018) and
more  comprehensive  geological  information  from  actual  mining  fronts. AMAK's  JORC  Compliant  Reserves  (January  2019)  are  given

Ore reserves were estimated using metal prices of USD $1.11 per pound for zinc, $2.50 per pound for copper, $1,200 per ounce for gold
and $15.00 per ounce for silver.

Mineable (recoverable) reserves include:

•

•

20% sidewall dilution in the stope
production

0.07Mt surface
stockpiles

Mineable (recoverable) reserves exclude:

• Mining of any mineralization less than mineable width of

1.0m

•

Sill Pillar (which was previously included). Technically, it is not mineable with current underground infrastructure and
backfilling practices, so this pillar (0.6Mt) excluded from Reserves

• All of the Moyeath orebody since it is categorized as

Inferred

• Any low grade (CuEq<1.01%) material (0.4Mt) which has to mined out and stored

separately

The  updated  reserves  reflect  a  1.5M  tonnes  increase  to  the  MRE  of  January  2018,  due  to  additional  drilling  at  Moyeath  and  Saadah
orebodies. The depth of three orebodies are not tested yet and underground drilling will continue in 2019 and coming years to extend the
orebody at depth.

Access and all mine services already exist at the Moyeath orebody and AMAK recently started ore mining in the last quarter of 2018. In
2019, AMAK estimates that approximately 50,000 tonnes will be mined out from Moyeath orebody. A drilling program of 8,000 meters (8
months) has been completed at Moyeath, which upgraded 0.8M tonnes of inferred class to indicated class, which eventually mine designed
and included in the life of mine schedule. AMAK believes that the Moyeath orebody is high grade for zinc and average grade as a copper.
AMAK  believes  that  Moyeath  is  the  most  attractive  opportunity  for  an  extended  life  and  higher  zinc  metal  recovery  through  the  life  of
mine.

The metallurgical recoveries are assumed as 83% for copper and 75% for zinc after 2019. Actual metal recoveries in 2018 increased
throughout the year so that these recovery assumptions are realistic and in line with actual performance of the process plant.

PART II

Item 5. Market for Registrant's Common Equity, Related Stockholder Matters, and Issuer Purchases of Equity Securities.

Our common stock traded on the New York Stock Exchange ("NYSE") under the symbol "TREC".

At March 4, 2019, there were approximately 535 recorded holders (including brokers' accounts) of the Company's common stock. We have
not  paid  any  dividends  since  our  inception  and  have  instead  deployed  earnings  to  fund  the  development  of  our  business. Any  future
determination  to  pay  dividends  will  be  at  the  discretion  of  our  board  of  directors  and  will  depend  on  our  financial  condition,  results  of
operations, capital expenditure requirements, restrictions contained in current and future financing instruments, and other factors that our
board  of  directors  deems  relevant.  In  addition,  our  ability  to  pay  dividends  depends  in  part  on  our  receipt  of  cash  dividends  and
distributions  from  our  subsidiaries.  The  terms  of  certain  of  our  current  debt  instruments  restrict  the  ability  of  our  subsidiaries  to  pay
dividends, as may the terms of any of our future debt or preferred securities.

Total Stockholder Return

The following graph compares the cumulative total stockholder return on our common stock against the NYSE Composite Index and the
S&P Specialty Chemical Index, for the five years ending December 31, 2018. The graph was constructed on the assumption that $100 was
invested in our common stock and each comparative on December 31, 2013, and that any dividends were fully reinvested.

(1) Non-GAAP financial measure. See the information under the heading "Non-GAAP Financial Measures" below for additional

information about this measures and a reconciliation to the most directly comparable financial measure under United States
generally accepted accounting principles (“GAAP”).

Non-GAAP Financial Measures

We include in this Annual Report the non-GAAP financial measures of EBITDA, Adjusted EBITDA, and Adjusted Net Income (Loss) and
provide reconciliations from our most directly comparable GAAP financial measure to those measures.

We  believe  these  financial  measures  provide  users  of  our  financial  statements  with  supplemental  information  that  may  be  useful  in
evaluating our operating performance. We also believe that such non–GAAP measures, when read in conjunction with our operating results
presented under GAAP, can be used to better assess our performance from period to period and relative to performance of other companies
in our industry, without regard to financing methods, historical cost basis or capital structure. These measures are not measures of financial
performance  or  liquidity  under  GAAP  and  should  be  considered  in  addition  to,  and  not  as  a  substitute  for,  analysis  of  our  results  under
GAAP.

EBITDA and Adjusted EBITDA: We define EBITDA as net income (loss) plus interest expense (benefit) including derivative gains and
losses, income taxes, depreciation and amortization. We define Adjusted EBITDA as EBITDA plus share–based compensation, plus
restructuring and severance expenses, plus losses on extinguishment of debt, plus or minus equity in AMAK's earnings and losses or gains
from equity issuances, and plus or minus gains or losses on acquisitions.

Adjusted Net Income (Loss): We define Adjusted Net Income (Loss) as net income (loss) plus or minus tax effected equity in AMAK's
earnings and losses, minus tax effected restructuring and severance expenses, and adjustments for tax law changes in 2017.

The following table presents a reconciliation of net income (loss), our most directly comparable GAAP financial performance measure for
each of the periods presented, to EBITDA, Adjusted EBITDA, and Adjusted Net Income.

Forward Looking Statements

Some of the statements and information contained in this Annual Report on Form 10-K may constitute forward-looking statements within
the  meaning  of  the  Private  Securities  Litigation  Reform Act  of  1995.  Statements  regarding  the  Company's  financial  position,  business
strategy and plans and objectives of the Company's management for future operations and other statements that are not historical facts, are
forward-looking  statements.  Forward-looking  statements  are  often  characterized  by  the  use  of  words  such  as  "outlook,"  "may,"  "will,"
"should," "could," "expects," "plans," "anticipates," "contemplates," "proposes," "believes," "estimates," "predicts," "projects," "potential,"
"continue," "intend," or the negative of such terms and other comparable terminology, or by discussions of strategy, plans or intentions.

Part II, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations, and in our other filings with the
SEC.

There may be other factors of which we are currently unaware or deem immaterial that may cause our actual results to differ materially
from the forward-looking statements. In addition, to the extent any inconsistency or conflict exists between the information included in this
report and the information included in our prior reports and other filings with the SEC, the information contained in this report updates and
supersedes such information.

Forward-looking statements are based on current plans, estimates, assumptions and projections, and, therefore, you should not place undue
reliance on them. Forward-looking statements speak only as of the date they are made, and we undertake no obligation to update them in
light of new information or future events.

Overview

The following discussion and analysis of our financial results, as well as the accompanying consolidated financial statements and related
notes to consolidated financial statements to which they refer, are the responsibility of the management of the Company. Our accounting
and  financial  reporting  fairly  reflect  our  business  model  involving  the  manufacturing  and  marketing  of  specialty  petrochemical  products
and specialty waxes. Our business model involves the manufacture and sale of tangible products and providing custom processing services.
Our consistent approach to providing high purity products and quality services to our customers has helped to sustain our current position
as a preferred supplier of various specialty petrochemical products.

Business Environment and Risk Assessment

We  believe  we  are  well-positioned  to  participate  in  the  US  chemical  industry  growth  driven  by  new  investments  and  overall  economic
growth. While petrochemical prices are volatile on a short-term basis and depend on the demand of our customers' products, our investment
decisions are based on our long-term business outlook using a disciplined approach in selecting and pursuing the most attractive investment
opportunities.

Specialty Petrochemical Operations

SHR's worldwide specialty petrochemical demand increased during 2018 compared to 2017. Product sales revenue increased 19.3% driven
primarily by volume growth of 7.6%. Overall product prices also increased compared to 2017 primarily due to higher feedstock costs in
2018  compared  to  2017.  We  continued  to  emphasize  our  competitive  advantages  achieved  through  our  high  quality  products  and
outstanding customer service and responsiveness. We are also focused on improving operations and plant reliability.

During  2018  feedstock  prices  were  about  24%,  or  $0.28  per  gallon,  higher  than  2017  reflecting  higher  crude  oil  prices. After  steadily
increasing  for  most  of  2018  feedstock  prices  declined  sharply  in  the  fourth  quarter  of  2018. About  60%  of  our  prime  products  are  sold
under  formula  pricing  whereby  feedstock  costs  are  passed  along  to  the  customer  typically  with  a  one  month  lag.  Thus,  when  feedstock
prices start rising, we experience lower margins as formula pricing lags feedstock costs. During most of 2018 prime products margins were
pressured due to rising feedstock costs and as a result of greater competitive pricing pressure on prime products sales that are based on non-
formula  pricing.  Our  byproduct  margins  were  under  pressure  in  the  fourth  quarter  due  to  the Advanced  Reformer  outage  as  we  sold
byproducts at prices below the cost of feedstock.

Specialty Wax Operations

Most wax markets are mature. Key applications for our polyethylene waxes are in hot melt adhesives ("HMA"), plastic processing, PVC
lubricants and inks, paints and coatings, where they act as surface or rheology modifiers. The HMA market is expected to grow at a higher
rate  than  GDP  growth  due  to  growth  in  the  developing  markets  and  increases  in  packaging  requirements  due  to  changes  in  consumer
purchasing  (shift  to  home  deliveries  via  the  internet)  in  developed  economies.  Road  marking  paints  are  also  expected  to  grow  at  rates
exceeding GDP growth based upon an expectation that there will be infrastructure investment in the U.S.   The PVC market is expected to
grow at GDP rates; however, we expect to get more traction of our products within this market with acceptance of our  new  PVC  grade
waxes. The global wax market is benefiting from the reduction of paraffin wax availability from large refiners as they move toward more
hydrocracking and hydroisomerization to produce group III lube oils and distillate. Our wax sales volume increased approximately 5% in
2018 from 2017 while revenues increased approximately 13%.

Restructuring and Severance Impact

During 2018, the Company incurred restructuring and severance expenses of $2.3 million which are included in General and Administrative
Expenses.  These  expenses  are  primarily  attributable  to  the  termination  of  certain  executives  during  2018  as  part  of  the  restructuring  of
executive  management  and  to  the  reduction  in  the  workforce  at  our  Silsbee,  Texas  facility  in  December  2018.  These  expenses  relate  to
severance,  stock  compensation  for  continued  vesting  of  time-vested  shares  issued  under  the  Company's  long-term  incentive  plan,  and
certain  employee  benefits  including  medical  insurance  and  vacation. As  of  December  31,  2018,  approximately  $1.1  million  had  been
incurred, and an additional liability of $1.2 million was accrued related to future benefits.

Hurricane Harvey Impact

The financial impact of Hurricane Harvey to our company was significant. Harvey made landfall on the Texas Gulf Coast on August 25,
2017, and affected operations at both SHR and TC. We estimated the total negative impact to 2017 EBITDA ranged from approximately
$1.5  million  to  $1.8  million.  This  included  expenses  related  to  generator  rentals,  overtime  labor,  and  maintenance  and  repairs  of
approximately $0.7 million. This estimate also included lost sales due to outages at customer and supplier facilities. Neither of our facilities
suffered any significant damage.

Our  days  sales  outstanding  in  accounts  receivable  remained  steady  from  2016  to  2017  but  decreased  from  2017  to  2018  due  to  greater
increase in sales revenue relative to the increase in receivables.

Our days sales outstanding in inventory decreased from 2017 to 2018 due to a planned reduction in inventory at TC.

Our  days  sales  outstanding  in  accounts  payable  decreased  due  to  a  decrease  in  payables  because  of  the  completion  of  certain  capital
construction projects at SHR.

Sources and Uses of Cash

Operating activities generated cash of $19.9 million during fiscal 2018 as compared with $30.8 million of cash provided during fiscal 2017.
Net income decreased by $20.3 million and cash provided by operations decreased by $10.9 million from 2017 to 2018 due primarily to the
following factors:

• Net  income  for  2018  included  a  non-cash  depreciation  and  amortization  charge  of  $14.4  million  as  compared  to  2017  which

included a non-cash depreciation and amortization charge of $11.0 million;

• Net income for 2018 included non-cash deferred income tax liability of $1.6 million as compared to non-cash deferred income

tax liability of $5.8 million in 2017;

Income  taxes  receivable  decreased  $5.4  million  in  2018  (primarily  due  to  collection  of  federal  and  state  research  and
development credits, carryback claims, and refunds of tax payments on deposit) as compared to an increase of $1.6 million in
2017 (primarily due to federal and state research and development credits and carryback claims); and

Inventory  decreased  $1.9  million  in  2018  as  compared  to  an  increase  of  $0.6  million  in
2017.

These significant sources of cash were partially offset by the following decreases in cash provided by operations:

• Net income for 2018 included a non-cash equity in loss from AMAK of $0.9 million as compared to a non-cash equity in loss

from AMAK of $4.3 million in 2017; and

• Accounts payable and accrued liabilities decreased $2.2 million in 2018 as compared to a decrease of $7.0 million in 2017 due to

the release of post-retirement obligations to a former director as well as the completion of certain capital projects.

Operating activities generated cash of $30.8 million during fiscal 2017 as compared with $28.5 million of cash provided during fiscal 2016.
Net income decreased by $1.4 million from 2016 to 2017; however, cash provided by operations increased by $2.3 million due primarily to
the following factors:

• Net income for 2017 included a non-cash equity in loss from AMAK of $4.3 million as compared to a non-cash equity in loss

from AMAK of $1.5 million and a $3.2 million gain from additional equity issuance by AMAK in 2016;

• Net income for 2016 included a non-cash bargain purchase gain from the B Plant acquisition of $11.5 million as compared to

2017 which had no gain;

• Net  income  for  2017  included  a  non-cash  depreciation  and  amortization  charge  of  $11.0  million  as  compared  to  2016  which

included a non-cash depreciation and amortization charge of $9.8 million;

• Accounts payable and accrued liabilities increased $7.0 million in 2017 (primarily due to increased construction expenditures) as

compared to an increase of $3.2 million in 2016 (also primarily due to construction projects);

•

•

Prepaid expenses and other assets increased $0.8 million in 2017 (primarily due to the inventorying of spares parts) as compared
to an increase of $1.0 million in 2016 (primarily due to license fees for the Advanced Reformer unit being constructed); and

Inventory increased $0.6 million in 2017 (primarily due to an increase in deferred sales which increases inventory in transit) as
compared to an increase of $2.1 million in 2016 (due to lower sales volume).

These significant sources of cash were partially offset by the following decreases in cash provided by operations:

• Net income for 2017 included non-cash deferred income tax liability of $5.8 million as compared to non-cash deferred income

tax benefit of $8.7 million in 2016;

•

•

Income  taxes  receivable  increased  $1.6  million  in  2017  (primarily  due  to  federal  and  state  claims  filed  for  research  and
development credits and carryback claims) as compared to an decrease of $3.7 million in 2016 (primarily due to overpayments
being applied to 2016 estimated taxes); and

Trade receivables increased $3.6 million in 2017 (primarily due to an increase in the average selling price) as compared to an
increase  of  $2.8  million  in  2016  (due  to  an  increase  in  wax  sales  in  December  and  longer  payment  terms  for  some  foreign
customers because of increased shipping times);

Investing Activities

Cash  used  by  investing  activities  during  fiscal  2018  was  approximately  $19.9  million,  representing  a  decrease  of  approximately  $31.8
million  compared  to  fiscal  2017.  The  majority  of  the  decrease  was  due  to  the  completion  of  construction  projects  for  the  Advanced
Reformer unit. During 2018, major capital expenditures included $14.9 million to complete the Advanced Reformer unit, which includes
$1  million  insurance  deductible  related  to  the  February  2018  fire  and  $3  million  for  the  catalyst  replacement  in  December  2018,  $1.3
million for a rail spur addition at SHR and 0.5 million for a loading rack at SHR.

Cash  used  by  investing  activities  during  fiscal  2017  was  approximately  $51.7  million,  representing  an  increase  of  approximately  $11.2
million  over  the  corresponding  period  of  2016.  The  majority  of  the  increase  was  due  to  the  construction  projects  for  the
hydrogenation/distillation unit and the Advanced Reformer unit. During 2017, we expended $10.8 million on the hydrogenation/distillation
project, $0.9 million to upgrade B Plant, $32.5 million to construct the Advanced Reformer unit, $1.9 million for railspur addition, $1.0
million  for  additional  tankage  and  upgrades  to  existing  tankage,  $0.9  million  for  transport  trucks,  and  $3.7  million  on  various  plant
improvements and equipment.

Financing Activities

Cash  provided  by  financing  activities  during  fiscal  2018  was  approximately  $3.7  million  versus  cash  provided  of  $15.5  million  during
fiscal 2017. During 2018, we increased our line of credit and consolidated our acquisition and term loans. We made principal payments of
$15.4 million on our term debt. We drew $18.2 million on our revolving line of credit, primarily to fund our capital projects. See Note 12
for additional discussion on long-term debt.

Cash provided by financing activities during fiscal 2017 was approximately $15.5 million versus cash provided of $1.8 million during the
corresponding period of 2016. During 2017 we made principal payments of $8.7 million on our acquisition loan and $1.7 million on our
term debt. We drew $26.0 million on our line of credit primarily to fund our capital projects.

Credit Agreement

In October 2014, TOCCO, SHR, GSPL and TC (SHR, GSPL and TC collectively the “Guarantors”) entered into an amended and restated
credit agreement (as amended to the date hereof, the “ARC Agreement”), which originally provided (i) a revolving credit facility (which we
refer to herein as the “Revolving Facility”) with revolving commitments of $40.0 million and (ii) term loan borrowings consisting of (A) a
$70.0 million single advance term loan incurred to partially finance the acquisition of TC (which we refer to as the “acquisition loan”) and
(B) a $25.0 multiple advance term loan facility for which borrowing availability ended on December 31, 2015 (which we collectively refer
to herein as the “Term Loan Facility” and, together with the Revolving Facility, the “Credit Facilities”).

Only  July  31,  2018,  TOCCO  and  the  Guarantors  entered  into  a  Fourth Amendment  to  the ARC Agreement  (the  “Fourth Amendment”)
pursuant  to  which  the  revolving  commitments  under  the  Revolving  Facility  were  increased  to  $75.0  million.  Pursuant  to  the  Fourth
Amendment,  total  borrowings  under  the  Term  Loan  Facility  were  increased  to  $87.5  million  under  a  single  combined  term  loan,  which
comprised new term loan borrowings together with approximately $60.4 million of previously outstanding term loans under the Term Loan
Facility. The $60.4 million of previously outstanding term loans included the remaining outstanding balances on the Acquisition loan and
the multiple advance term loan facility described above. Proceeds of the new borrowings under the Term Loan Facility were used to repay
a portion of the outstanding borrowings under the Revolving Facility and pay fees and expenses of the transaction. As of December 31,
2018, we had $18 million in borrowings outstanding under the Revolving Facility and $84.5 million in borrowings outstanding under the
Term  Loan  Facility.  In  addition,  we  had  the  ability  to  borrow  an  additional  approximately  $18  million  under  our  Revolving  Facility  at
December  31,  2018.  TOCCO’s  ability  to  make  additional  borrowings  under  the  Revolving  Credit  Facility  at  December  31,  2018  was
limited by, and in the future may continue to be limited by, our obligation to maintain compliance with the covenants contained in the ARC
Agreement (including maintenance of a maximum Consolidated Leverage Ratio and minimum Consolidated Fixed Charge Coverage Ratio
(each as defined in the ARC Agreement)).

The  maturity  date  for  the ARC Agreement  is  July  31,  2023.  Subject  to  the  lenders  acceptance  of  any  increased  commitment  and  other
conditions, we have the option, at any time, to request an increase to the commitment under the Revolving Facility and/or the Term Loan
Facility by an additional amount of up to $50.0 million in the aggregate.

Borrowings under each of the Credit Facilities bear interest on the outstanding principal amount at a rate equal to LIBOR plus an applicable
margin of 1.25% to 2.50% or, at our option, the Base Rate plus an applicable margin of 0.25% to 1.50%, in each case, with the applicable
margin  being  determined  based  on  the  Consolidated  Leverage  Ratio  of  TOCCO. A  commitment  fee  between  0.20%  and  0.375%  is  also
payable quarterly on the unused portion of the Revolving Facility. For 2018, the effective interest rate for the Credit Facilities was 4.19%.
Borrowings under the Term Loan Facility are subject to quarterly amortization payments based on a commercial style amortization method
over a twenty year period; provided, that the final principal installment will be paid on the maturity date and will be in an amount equal to
the outstanding borrowings under the Term Loan Facility on such date.

Pursuant to the terms of the ARC Agreement, TOCCO must maintain a maximum Consolidated Leverage Ratio of 4.75 to 1.00 for the four
fiscal quarters ended December 31, 2018, 4.25 to 1.00 for the four fiscal quarters ended March 31, 2019, 4.00 to 1.00 for the four fiscal
quarters ended June 30, 2019 and 3.75 to 1.00 for the four fiscal quarters ended September 30, 2019. For the four  fiscal  quarters  ended
December 31, 2019 and each fiscal quarter thereafter, TOCCO must maintain a Consolidated Leverage Ratio of 3.50 to 1.00 (subject to
temporary increase following certain acquisitions). Additionally, TOCCO must maintain a minimum Consolidated Fixed Charge Coverage
Ratio as of the end of any fiscal quarter of 1.15 to 1.00.

The  ARC  Agreement  contains,  among  other  things,  other  customary  covenants,  including  restrictions  on  the  incurrence  of  additional
indebtedness,  the  granting  of  additional  liens,  the  making  of  investments,  the  disposition  of  assets  and  other  fundamental  changes,
transactions with affiliates and the declaration of dividends and other restricted payments. The ARC Agreement further includes customary
representations and warranties and events of default, and upon occurrence of such events of default the outstanding obligations under the
ARC Agreement may be accelerated and become immediately due and payable and the commitment of the

lenders to make loans under the ARC Agreement may be terminated. We were in compliance with all covenants at December 31, 2018.

Anticipated Cash Needs

We  believe  that  the  Company  is  capable  of  supporting  its  operating  requirements  and  capital  expenditures  through  internally  generated
funds supplemented with borrowings under our Credit Facilities.

Gross Revenue

2017-2018

Revenues increased from 2017 to 2018 by approximately 18.7% due to an increase in specialty petrochemical sales volume and an increase
in average selling prices.

2016-2017

Revenues increased from 2016 to 2017 by approximately 15.6%  due  to  an  increase  in  sales  volume  of  9.1%  and  an  increase  in  average
selling price of 7.7% partially offset by a decrease in processing fees of 21.7%.

Specialty Petrochemical Product Sales

2017-2018

Specialty petrochemical product sales increased 19.3% from 2017 to 2018 due to an increase in total sales volume of 7.6% and an increase
in average selling price of 10.9%. Our average selling price increased partly because of higher feedstock costs. A large portion of our prime
products sales are contracted with pricing formulas which are tied to prior month Natural Gasoline prices which is our primary feedstock.
Average delivered feedstock price for 2018 was 21.1% higher than 2017 as Natural Gasoline prices rose with crude oil prices for most of
the year but then declined sharply in the fourth quarter. The increase in average selling prices was also due to higher non-formula pricing
for  our  prime  products. Additionally,  prices  for  byproducts  in  2018  were  about  24%  higher  than  in  2017  due  to  higher  prices  for  the
components in our byproducts stream. This also contributed to higher overall selling prices. Byproduct prices fell significantly during the
fourth  quarter  due  to  the Advanced  Reformer  outage  and  inability  to  upgrade  byproducts. Additionally,  in  the  fourth  quarter  byproduct
prices fell faster than feedstock prices resulting in negative margins.

Prime product sales volume (total specialty petrochemical product sales volume less byproduct sales volume) increased 8.5% from 2017 to
2018 as demand was greater in all of our end-use markets and especially in the Canadian oil sands market. Sales to the Canadian oil sands
market continues to be volatile. We believe the volatility in demand is primarily based on continued manufacturing efficiencies at customer
sites and by the crude oil pricing environment. Margins on our specialty petrochemical products continued to be negatively impacted by
shortfall  fees  that  we  incurred  due  to  feedstock  purchases  below  minimum  amounts  as  prescribed  by  our  agreement  with  suppliers.
However the amount of the penalties in 2018 were significantly less than 2017.

Foreign sales volume accounted for approximately 25.5% of volume and 27.6% of revenue for specialty petrochemical product sales during
2018 as compared to 20.4% of volume and 23.3% of revenue during 2017. The increase in foreign sales volume was

Table of Contents

due to higher demand in the Canadian oils sands market. Excluding oil sands, foreign sales volumes in 2018 grew by 22% from 2017.

2016-2017

Specialty petrochemical product sales increased 17.5% from 2016 to 2017 due to an increase in total sales volume of 9.1% and an increase
in average selling price of 7.7%. Our average selling price increased partly because a large portion of our sales are contracted with pricing
formulas which are tied to prior month Natural Gasoline prices which is our primary feedstock. Average delivered feedstock price for 2017
was  17.8%  higher  than  2016. Additionally,  prices  for  byproducts  were  about  17%  higher  than  in  2016  which  also  contributed  to  higher
overall  selling  prices.  Prime  product  sales  volume  (total  specialty  petrochemical  product  sales  volume  less  byproduct  sales  volume)
increased 9.5% from 2016 to 2017 primarily due to higher demand across many of our end-use markets. Sales to the Canadian oil sands
market were down from 2016 due to the continued downturn in that market. Margins on our specialty petrochemical products continued to
be  negatively  impacted  by  shortfall  fees  that  we  incurred  due  to  feedstock  purchases  below  minimum  amounts  as  prescribed  by  our
agreement with suppliers. The amount of the penalties in 2017 was approximately the same as in 2016.

Foreign sales volume accounted for approximately 20.4% of volume and 23.3% of revenue for specialty petrochemical product sales during
2017 as compared to 22.7% of volume and 26.3% of revenue during 2016. The decline in foreign sales volume was due to lower demand in
the Canadian oils sands market. Excluding oil sands, foreign sales volumes in 2017 grew by 8.1% from 2016.

Processing Fees

2017-2018

Processing fee were approximately flat from 2017 to 2018.

2016-2017

Processing fees decreased 21.7% from 2016 to 2017 primarily due to a reduction in fees associated with a customer who reimbursed us for
installation expenses plus a markup. We were successful in negotiating a contract extension with one of our processing customers whose
contract was set to expire at the end of 2017.

Cost of Sales (includes but is not limited to raw materials, total operating expense, natural gas, operating labor and transportation)

2017-2018

Cost  of  Sales  increased  32.3%  from  2017  to  2018  due  to  higher  raw  material  costs,  higher  operating  expense  and  the  increase  in  sales
volume. Our average delivered feedstock cost per gallon increased approximately 21% over 2017 and volume processed increased about
8%. We use natural gasoline as our feedstock which is the heavier liquid remaining after ethane, propane and butanes are removed from
liquids  produced  by  natural  gas  wells.  The  material  is  a  commodity  product  in  the  oil/petrochemical  markets  and  generally  is  readily
available. The price of natural gasoline is well correlated with the price of crude oil. With the start up and stable operation of our Advanced
Reformer unit we continue to convert the lower value components in our feed into higher value products, thereby allowing us to sell our
byproducts at higher prices than would be realized without the Advanced Reformer unit.

2016-2017

Cost of Sales increased 15.8% from 2016 to 2017 primarily due to the increase in sales volume and higher raw material costs. Our average
delivered  feedstock  cost  per  gallon  increased  17.8%  over  2016  and  volume  processed  increased  10.0%.  We  use  natural  gasoline  as
feedstock which is the heavier liquid remaining after ethane, propane and butanes are removed from liquids produced by natural gas wells.
The material is a commodity product in the oil/petrochemical markets and generally is readily available.

Total Operating Expense (includes but is not limited to natural gas, operating labor, depreciation, and transportation)

2017-2018

Total Operating Expense increased 24.4% from 2017 to 2018 resulting in a $14.4 million increase 2017. The key drivers for the increase
were transportation costs, operating labor and depreciation. Transportation costs increased due to higher sales volume, higher rail freight
rates and other logistics costs. Operating labor costs were higher due to higher maintenance and contract labor costs primarily associated
with the start-up of the Advanced Reformer unit, maintenance and repair costs associated with a toll processing unit and other maintenance
activities. Approximately 12.8% of our labor costs were capitalized in 2018 primarily due to the construction of the Advanced Reformer
unit; whereas, in 2017 approximately 28% was capitalized.

31

Table of Contents

We implemented a reorganization and workforce reduction at our Silsbee, Texas facility which reduced the workforce by about 20% at the
end  of  2018.  We  expect  to  realize  approximately  $2.5  million  in  annual  cost  savings  as  a  result  of  this  action.  We  took  a  charge  of
approximately $0.4 million for severance related to this action.

Natural  gas  expense  increased  14.9%  from  2017  to  2018  due  to  an  increase  in  the  average  per  unit  cost  and  volume  consumed.
Consumption was greater than in 2017 both due to higher sales volume and inefficiencies related to the start-up and operation issues with
the Advanced Reformer unit. The average price per MMBTU for 2018 was up about 3.8% from 2017 while volume consumed increased to
approximately 1,684,000 MMBTU from about 1,509,000 MMBTU.

2016-2017

Total Operating Expense increased 0.3% from 2016 to 2017. Natural gas, labor, and transportation are the largest individual expenses in
this category; however, not all of these increased.

Natural gas expense increased 48.8% from 2016 to 2017 due to an increase in the average per unit cost and volume consumed. The average
price  per  MMBTU  for  2017  was  $3.24  whereas,  for  2016  the  average  per  unit  cost  was  $2.61.  Volume  consumed  increased  to
approximately 1,509,000 MMBTU from about 1,294,000 MMBTU.

Labor costs declined 3.0% from 2016 to 2017 despite a 3.8% increase in headcount from year end 2016 to year end 2017. Approximately
19.9% of our labor costs were capitalized in 2017 due to the construction of the Advanced Reformer unit; whereas, in 2016 approximately
12.0% was capitalized.

Transportation costs were higher by 4.7% primarily due to the increase in sales volume.

General and Administrative Expense

2017-2018

General and Administrative costs increased 11.4% from 2017 to 2018 primarily due to restructuring and severance costs in 2018. There
were no restructuring and severance expenses in 2017.

2016-2017

General  and  Administrative  costs  increased  11.7%  from  2016  to  2017  primarily  due  to  an  increase  in  property  taxes  because  of  the
expiration of abatements. Group insurance and administrative labor costs also increased.

Depreciation

2017-2018

Depreciation  expense  increased  41.6%  or  approximately  $2.6  million  from  2017  to  2018  primarily  due  to  the  start-up  of  the Advanced
Reformer unit and the resulting increase of our depreciable base.

2016-2017

Depreciation expense increased 8.3% from 2016 to 2017 primarily due to 2016 capital expenditures increasing our depreciable base.

Capital Expenditures

2017-2018

Capital  expenditures  in  2018  declined  $15.1  million  from  2017  mostly  due  to  the  completion  of  the  Advanced  Reformer  unit.  See
discussion under "Capital Resources and Requirements" below for more detail.

2016-2017

Capital  expenditures  increased  63.7%  from  2016  to  2017.  See  discussion  under  "Capital  Resources  and  Requirements"  below  for  more
detail.

Product Sales

2017-2018

Product sales revenue increased 13.4% and product sales volume increased 5.3% from 2017 to 2018 primarily due to higher on-purpose PE
wax sales which benefited from continued growth in growth in our high value waxes. Polyethylene wax sales saw volume increases of 3.5%
and revenue from polyethylene wax increased approximately 15.4% both as a result of greater sales volume and a higher value sales mix.
Average wax sales price was approximately 9% higher in 2018 compared to 2017.

2016-2017

Product sales revenue increased 17.2% and product sales volume increased 4.4% from 2016 to 2017 primarily due to on-purpose PE wax
sales which we were distributing in Latin America for a third party as well as, significant growth in our high value waxes. Polyethylene wax
sales saw volume increases of 1.3% and revenue increases of 12.8%. 

Processing Fees

2016-2017

Processing fees increased 8.9% from 2016 to 2017 primarily due to the addition of new customers and an increase in existing customer
volumes. Growth was limited by significant operational issues in existing equipment and in the new hydrogenation/distillation unit.

Cost of Sales

2017-2018

Cost of Sales increased 5.7% from 2017 to 2018 due to increases in labor, maintenance, utilities and depreciation which were partially offset
by lower wax material costs.   Labor increased approximately due to increased overtime and the addition of personnel to support the new
hydrogenation/distillation  unit  which  came  on  line  in  2017  as  well  as  to  support  other  custom  processing  projects.  Maintenance  costs
increased primarily as a result of the start-up of hydrogenation/distillation and the related operating issues in 2018. Utility costs increased
mainly due to greater consumption.

2016-2017

Cost of Sales increased 30.5% from 2016 to 2017 due to increases in material cost, labor, freight, equipment maintenance, and natural gas
utilities.  Material  cost  increased  primarily  due  to  material  costs  associated  with  the  on-purpose  PE  wax  sales  we  distributed  into  Latin
America  for  a  third  party.  Labor  increased  due  to  increased  overtime  and  the  addition  of  personnel  to  operate  the  new
hydrogenation/distillation unit when it came online in 2017. Freight increased due to the increase in shipments and a change in our shipping
terms. We now ship most products with destination terms. Equipment maintenance increased primarily due to the addition of B Plant and
the introduction of new custom processing projects. Natural gas  utilities  increased  due  to  an  increase  in  the  per  unit  cost  and  in  volume
consumed because of B Plant and the new hydrogenation/distillation unit.

General and Administrative Expense

2017-2018

General and Administrative costs increased 2.5% from 2017 to 2018.

2016-2017

General and Administrative costs increased 2.3% from 2016 to 2017 primarily due to an increase in sales personnel, property taxes, and
property insurance due to the addition of B Plant.

Depreciation and Amortization

2017-2018

Depreciation and amortization increased 17.1% from 2017 to 2018 primarily due to start up of the hydrogenation/distillation project in the
second half of 2017.

General corporate expenses increased from 2017 to 2018 primarily due to restructuring and severance expenses, offset by the cancellation
and reversal of stock compensation expense and other post retirement benefits awarded to Mr. Hatem El Khalidi. See Note 14 for further
discussion.

2016-2017

General corporate expenses increased from 2016 to 2017 primarily due to an increase in officer compensation, accounting fees, and legal
fees.  Officer  compensation  increased  in  2017  due  to  the  addition  of  an  officer  in  late  2016  and  and  an  accrual  for  executive  bonuses.
Accounting and legal fees increased due to additional time required for restatements issues and other matters.

Equity in Losses of AMAK/Gain on Equity Issuance of AMAK

2017-2018

Equity in Losses of AMAK decreased 78.9% from 2017 to 2018 due to a number of reasons as discussed below.

The mine was fully operational in 2018 as compared to operating on an improving basis throughout 2017. In 2017 costs were increased as
the mine was not operating at full capacity. Metal prices remained strong in 2018.

Shipments increased 105% from 2017 to 2018 as indicated in the table below. AMAK volumes in dry metric tons (dmt) for 2018 and 2017
were as follows:

Equity in Losses of AMAK increased 188.1% from 2016 to 2017 due to a number of reasons as discussed below.

The mine operated on an improving basis throughout 2017 while operations were closed for almost all of 2016. However, in 2017 because
the mine was not operating at full capacity but was working toward that goal, costs increased. Also, 2016 was positively affected by the
settlement from certain liabilities. Metal prices were strong in 2017 with zinc prices hitting a ten year high during the year.   There were no
unusual items in 2017.

Capital Resources and Requirements

2017-2018

Capital expenditures decreased 58% from 2017 to 2018. The majority of the decrease was due to completion of the Advanced Reformer
unit. During 2018 we expended approximately $14.9 million to complete the Advanced Reformer unit which includes $1 million insurance
deductible  related  to  the  February  2018  fire  and  $3  million  for  the  catalyst  replacement  in  December  2018,  $1.3  million  for  a  rail  spur
addition and $0.5 million for a truck loading rack.

2016-2017

Capital  expenditures  increased  27.4%  from  2016  to  2017.  The  majority  of  the  increase  was  due  to  the  construction  projects  for  the
hydrogenation/distillation unit and the Advanced Reformer unit. During 2017 we expended $10.8 million on the hydrogenation/distillation
project, $0.9 million to upgrade B Plant, $32.5 million to construct the Advanced Reformer unit, $1.9 million for railspur addition, $1.0
million  for  additional  tankage  and  upgrades  to  existing  tankage,  $0.9  million  for  transport  trucks,  and  $3.7  million  on  various  plant
improvements and equipment.

At  December  31,  2018,  there  was  approximately  $18  million  available  on  the  Company's  line  of  credit.  We  believe  that  operating  cash
flows along with credit availability will be sufficient to finance our 2019 operations and capital expenditures.

The majority of our operating lease obligations are for railcars as discussed in Note 14 of the Notes to Consolidated Financial Statements.
Purchase  obligations  are  primarily  related  to  commitments  for  our  capital  construction  projects.  The  anticipated  source  of  funds  for
payments due within three years that relate to contractual obligations is from a combination of continuing operations supplemented with
borrowings under our credit facility.

Impact of Inflation

Our  results  of  operations  and  financial  condition  are  presented  based  on  historical  cost.  While  it  is  difficult  to  accurately  measure  the
impact of inflation, we do not believe the overall effects of inflation, if any, on our results of operations and financial condition have been
material.

Investment in AMAK

Information concerning our investment in AMAK is set forth in Note 10 of the Notes to Consolidated Financial Statements.

New Accounting Standards

In May 2014 the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-9,  Revenue from
Contracts with Customers ("ASU 2014-9"). ASU 2014-9 supersedes the revenue recognition requirements of FASB Accounting Standards
Codification  ("ASC")  Topic  605, Revenue  Recognition  and  most  industry-specific  guidance  throughout  the  Accounting  Standards
Codification, resulting in the creation of FASB ASC Topic 606,  Revenue from Contracts with Customers. ASU 2014-9 requires entities to
recognize revenue in a way that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration
to  which  the  entity  expects  to  be  entitled  to  in  exchange  for  those  goods  or  services.  This  ASU  provides  alternative  methods  of
retrospective adoption and is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017. The
Company  completed  its  assessment  of  the  impact  of  the  adoption  of ASU  2014-9  across  all  revenue  streams.  This  included  reviewing
current accounting policies and practices to identify potential differences that would result from applying the requirements under the new
standard. We completed contract reviews and validated results of applying the new revenue guidance (Note 2). See Revenue Recognition
policy note.

In  February  2016,  the  FASB  issued ASU  No.  2016-02,  Leases  (Topic  842).  This  update  will  increase  transparency  and  comparability
among  organizations  by  recognizing  lease  assets  and  lease  liabilities  on  the  balance  sheet  and  disclosing  key  information  about  leasing
arrangements.  This  update  is  effective  for  annual  and  interim  reporting  periods  beginning  after  December  15,  2018,  including  interim
periods within those fiscal years. Early adoption is permitted. In July 2018, the FASB issued ASU No. 2018-11, Targeted Improvements to
ASC 842, Leases.  ASU 2018-11 provided entities with an alternative modified transition method to elect not to recast the comparative
periods  presented  when  adopting  ASC  842.  The  new  standard  provides  a  number  of  optional  practical  expedients  in  transition.  The
Company  expects  to  elect:  (1)  the  ‘package  of  practical  expedients’,  which  permits  it  not  to  reassess  under  the  new  standard  its  prior
conclusions  about  lease  identification,  lease  classification,  and  initial  direct  costs  and  (2)  the  use-of-hindsight.  In  addition,  the  new
standard provides practical expedients for an entity’s ongoing accounting that the Company anticipates making, such as the (1) the election
for certain classes of underlying asset to not separate non-lease components from lease components and (2) the election for short-term lease
recognition

36

exemption for all leases that qualify. The Company will adopt ASU 842 as of January 1, 2019, using the alternative modified transition
method.  In  preparation  of  adopting ASC  842,  the  Company  is  implementing  additional  internal  controls  to  enable  future  preparation  of
financial  information  in  accordance  with ASC  842.  The  Company  has  also  substantially  completed  its  evaluation  of  the  impact  on  the
Company’s  lease  portfolio.  The  Company  believes  the  largest  impact  will  be  on  the  consolidated  balance  sheets  for  the  accounting  of
facilities-related leases, which represents a majority of its operating leases it has entered into as a lessee. These leases will be recognized
under the new standard as right of use assets (“ROU”) operating lease liabilities. The Company will also be required to provide expanded
disclosures for its leasing arrangements. As of December 31, 2018, the Company had approximately $18.1 million of undiscounted future
minimum  operating  lease  commitments  that  are  not  recognized  on  its  consolidated  balance  sheets  as  determined  under  the  current
standard.  For  a  lessee,  the  results  of  operations  are  not  expected  to  significantly  change  after  adoption  of  the  new  standard.    While
substantially complete, the Company is still in the process of finalizing its evaluation of the effect of ASU 842 on the Company’s financial
statements and disclosures, including the determination of the Company’s incremental borrowing rate for each of the operating leases to
estimate the interest rate we would have to pay to borrow on a collateralized basis over a similar term for an amount equal to the lease
payments. The Company will finalize its accounting assessment and quantitative impact of the adoption during the first quarter of fiscal
year 2019.

In  January  2017  the  FASB  issued ASU  No.  2017-4,  Intangibles  –  Goodwill  and  Other  (Topic  350) .  The  amendments  in ASU  2017-4
simplify  the  measurement  of  goodwill  by  eliminating  Step  2  from  the  goodwill  impairment  test.  Instead,  under  these  amendments,  an
entity  should  perform  its  annual,  or  interim,  goodwill  impairment  test  by  comparing  the  fair  value  of  a  reporting  unit  with  its  carrying
amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair
value; however, the loss should not exceed the total amount of goodwill allocated to that reporting unit. The amendments are effective for
public business entities for the first interim and annual reporting periods beginning after December 15, 2019. Early adoption is permitted
for  interim  or  annual  goodwill  impairment  tests  performed  on  testing  dates  after  January  1,  2017.The  amendments  also  eliminate  the
requirements  for  any  reporting  unit  with  a  zero  or  negative  carrying  amount  to  perform  a  qualitative  assessment  and,  if  it  fails  that
qualitative test, to perform Step 2 of the goodwill impairment test. An entity still has the option to perform the qualitative assessment for a
reporting unit to determine if the quantitative impairment test is necessary. The Company has goodwill from prior business combination
and performs an annual impairment test or more frequently if changes or circumstances occur that would more-likely-than-not reduce the
fair  value  of  the  reporting  unit  below  its  carrying  value.  During  the  year  ended December  31,  2018,  the  Company  performed  its
impairment assessment and determined the fair value of the aggregated reporting units exceed the carrying value, such that the Company's
goodwill  was  not  considered  impaired. Although  the  Company  cannot  anticipate  future  goodwill  impairment  assessments,  based  on  the
most  recent  assessment,  it  is  unlikely  that  an  impairment  amount  would  need  to  be  calculated  and,  therefore,  the  Company  does  not
anticipate a material impact from these amendments to the Company's financial position and results of operations. The current accounting
policies and processes are not anticipated to change, except for the elimination of the Step 2 analysis.

In February 2018 the FASB issued ASU No. 2018-2,  Income Statement — Reporting Comprehensive Income (Topic 220): Reclassification
of  Certain  Tax  Effects  from  Accumulated  Other  Comprehensive  Income. ASU  2018-2  was  issued  to  address  the  income  tax  accounting
treatment of the stranded tax effects within other comprehensive income due to the prohibition of backward tracing due to an income tax
rate  change  that  was  initially  recorded  in  other  comprehensive  income  due  to  the  enactment  of  the  Tax  Cuts  and  Jobs Act  (TCJA)  on
December 22, 2017, which changed the Company's income tax rate from 35% to 21%. The amendments to the ASU changed US GAAP
whereby an entity may elect to reclassify the stranded tax effect from accumulated other comprehensive income to retained earnings. The
amendments of the ASU may be adopted in total or in part using a full retrospective or modified retrospective method. The amendments of
the ASU  are  effective  for  periods  beginning  after  December  15,  2018.  The  Company  believes  there  will  be  no  material  impact  to  the
consolidated financial statements as a result of this update.

In  June  2018,  the  FASB  issued ASU  No.  2018–07,  Improvements  to  Nonemployee  Share–Based  Payment  Accounting. ASU  2018–07
simplifies  the  accounting  for  share–based  payments  to  nonemployees  by  aligning  it  with  the  accounting  for  share–based  payments  to
employees,  with  certain  exceptions.  The  amendments  in  this ASU  are  effective  for  public  companies  for  fiscal  years  beginning  after
December  15,  2018,  including  interim  periods  within  that  fiscal  year.  The  Company  is  assessing  the  effect  of  ASU  2018–02  on  its
consolidated financial statements.

Critical Accounting Policies

Our  consolidated  financial  statements  are  based  on  the  selection  and  application  of  significant  accounting  policies.  The  preparation  of
consolidated  financial  statements  in  conformity  with  GAAP  requires  management  to  make  estimates  and  assumptions  that  affect  the
reported amounts of assets and liabilities and the reported amounts of net sales, expenses and allocated charges during the reported period.
Actual results could differ from those estimates. However, we are not currently aware of any reasonably likely events or circumstances that
would result in materially different results.

37

Table of Contents

We  believe  the  following  accounting  policies  and  estimates  are  critical  to  understanding  the  financial  reporting  risks  present  currently.
These matters, and the judgments and uncertainties affecting them, are essential to understanding our reported results. See Note 2 to the
Notes to the Consolidated Financial Statements for further information.

Inventories

Finished products and feedstock are recorded at the lower of cost, determined on the first-in, first-out method ("FIFO"); or market for SHR.
For TC, inventory is recorded at the lower of cost or market as follows: (1) raw material cost is calculated using the weighted-average cost
method and (2) product inventory cost is calculated using the specific cost method. See Note 7 to the Notes to the Consolidated Financial
Statements for more information.

Beginning  January  1,  2017,  due  to  expansion  of  our  plant  assets  at  SHR  and  TC,  we  began  inventorying  spare  parts  for  the  repair  and
maintenance of our plant, pipeline and equipment.

Revenue recognition

The  Company  adopted  Financial Accounting  Standards  Board  ("FASB") Accounting  Standards  Codification  ("ASC")  Topic  606  ("ASC
606"), Revenue from Contracts with Customers, and its amendments with a date of the initial application of January 1, 2018. As a result, the
Company has changed its accounting policy for revenue recognition as detailed below. ASC 606 outlines a single comprehensive model for
an  entity  to  use  in  accounting  for  revenue  arising  from  all  contracts  with  customers,  except  where  revenues  are  in  scope  of  another
accounting  standard. ASC  606  superseded  the  revenue  recognition  requirements  in ASC  Topic  605,  " Revenue  Recognition",  and  most
industry specific guidance. ASC Topic 606 sets forth a five-step model for determining when and how revenue is recognized. Under the
model,  an  entity  is  required  to  recognize  revenue  to  depict  the  transfer  of  goods  or  services  to  a  customer  at  an  amount  reflecting  the
consideration  it  expects  to  receive  in  exchange  for  those  goods  and  services. ASC  606  also  requires  certain  additional  revenue-related
disclosures.

The  Company  applied  the  modified  retrospective  approach  under ASC  606  which  allows  for  the  cumulative  effect  of  adopting  the  new
guidance on the date of initial application. Use of the modified retrospective approach means the Company's comparative periods prior to
initial application are not restated. The initial application was applied to all contracts at the date of the initial application.   The Company
has  determined  that  the  adjustments  using  the  modified  retrospective  approach  did  not  have  a  material  impact  on  the  date  of  the  initial
application along with the disclosure of the effect on prior periods.

Accounting Policy

Beginning  on  January  1,  2018,  revenue  is  measured  based  on  a  consideration  specified  in  a  contract  with  a  customer.  The  Company
recognizes revenue when it satisfies a performance obligation by transferring control over a product or service to a customer. In evaluating
when  a  customer  has  control  of  the  asset  we  primarily  consider  whether  the  transfer  of  legal  title  and  physical  delivery  has  occurred,
whether  the  customer  has  significant  risks  and  rewards  of  ownership,  and  whether  the  customer  has  accepted  delivery  and  a  right  to
payment exists. Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing
transaction, that are collected by the Company from a customer, are excluded from revenue. Shipping and handling costs associated with
outbound freight after control over a product has transferred to a customer are accounted for as a fulfillment cost and are included in cost of
product sales and processing. The Company does not offer material rights of return or service-type warranties.

For  2017  the  Company  recognized  revenue  according  to  FASB ASC  Topic  605  ("ASC  605"),  " Revenue  Recognition",  when:  (1)  the
customer  accepted  delivery  of  the  product  and  title  had  been  transferred  or  when  the  service  was  performed  and  the  Company  had  no
significant obligations remaining to be performed; (2) a final understanding as to specific nature and terms of the agreed upon transaction
had occurred; (3) price was fixed and determinable; and (4) collection was assured. Product sales generally met these criteria, and revenue
was  recognized,  when  the  product  was  delivered  or  title  was  transferred  to  the  customer.  Sales  revenue  was  presented  net  of  discounts,
allowances, and sales taxes. Freight costs billed to customers were recorded as a component of revenue. Revenues received in advance of
future  sales  of  products  or  prior  to  the  performance  of  services  were  presented  as  deferred  revenues.  Shipping  and  handling  costs  were
classified as cost of product sales and processing and were expensed as incurred.

Nature of goods and services

The following is a description of principal activities – separated by reportable segments – from which the Company generates its revenue.
For more detailed information about reportable segments, disaggregation of revenues, and contract balance disclosures, see Note 17.

Specialty petrochemical segment

The  specialty  petrochemical  segment  of  the  Company  produces  eight  high  purity  hydrocarbons  and  other  petroleum  based  products
including isopentane, normal pentane, isohexane and hexane. These products are used in the production of polyethylene, packaging,

Table of Contents

polypropylene,  expandable  polystyrene,  poly-iso/urethane  foams,  crude  oil  from  the  Canadian  tar  sands,  and  in  the  catalyst  support
industry. SHR's specialty petrochemical products are typically transported to customers by rail car, tank truck, iso-container and ship.

Product Sales - The Company sells individual (distinct) products to its customers on a stand-alone basis (point-of-sale) without any further
integration. There is no significant modification of any one or more products sold to fulfill another promised product or service within any
of the Company's product sale transactions. The amount of consideration received for product sales is stated within the executed invoice
with the customer. Payment is typically due and collected 30 to 60 days subsequent to point of sale.

Processing Fees - The Company's services consist of processing customer supplied feedstocks into custom products including, if requested,
services for forming, packaging, and arranging shipping. Pursuant to Tolling Agreements the customer retains title to the feedstocks and
processed products. The performance obligation in each Tolling Agreement transaction is the processing of customer provided feedstocks
into  custom  products  and  is  satisfied  over  time.      The  amount  of  consideration  received  for  product  sales  is  stated  within  the  executed
invoice with the customer. Payment is typically due and collected within 30 days subsequent to point of sale.

Specialty Wax segment

The specialty wax segment of the Company manufactures and sells specialty polyethylene and poly alpha olefin waxes and also provides
custom processing services for customers.

Product Sales - The Company sells individual (distinct) products to its customers on a stand-alone basis (point-of-sale) without any further
integration. There is no significant modification of any one or more products sold to fulfill another promised product or service within any
of the Company's product sale transactions. The amount of consideration received for product sales is stated within the executed invoice
with the customer. Payment is typically due and collected within 30 days subsequent to point of sale.

Processing Fees - The Company's promised services consist of processing customer supplied feedstocks into custom products including, if
requested, services for forming, packaging, and arranging shipping. Pursuant to Tolling Agreements and Purchase Order Arrangements, the
customer typically retains title to the feedstocks and processed products. The performance obligation in each Tolling Agreement transaction
and Purchase Order Arrangement is the processing of customer provided feedstocks into custom products and is satisfied over time.   The
amount of consideration received for product sales is stated within the executed invoice with the customer. Payment is typically due and
collected within 30 days subsequent to point of sale.

Long-lived Assets

Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be
recoverable from estimated future undiscounted cash flows. If the estimated future undiscounted cash flows are less than the carrying value
of the assets, we calculate the amount of impairment if the carrying value of the long-lived assets exceeds the fair value of the assets. Our
long-lived assets include our specialty petrochemical facility and our specialty synthetic wax facility.

Our specialty petrochemical facility and specialty synthetic wax facility are currently our revenue generating assets. The facilities were in
full operation at December 31, 2018.

Goodwill and other intangible assets

Goodwill  and  indefinite-lived  intangible  assets  are  tested  for  impairment  at  least  annually;  however,  these  tests  are  performed  more
frequently  when  events  or  changes  in  circumstances  indicate  that  the  asset  may  be  impaired.  Impairment  exists  when  carrying  value
exceeds fair value.

Definite-lived intangible assets are being amortized using discounted estimated future cash flows over the term of the related agreements.
We continually evaluate the reasonableness of the useful lives of these assets. Once these assets are fully amortized, they will be removed
from the consolidated balance sheets.

See Note 9 to the Notes to the Consolidated Financial Statements for additional information.

Investment in AMAK

We account for our investment in AMAK using the equity method of accounting under which we record in income our share of AMAK's
income or loss for each period. The amount recorded is also adjusted to reflect the amortization of certain differences between the basis in
our investment in AMAK and our share of the net assets of AMAK as reflected in AMAK's financial statements. Any proceeds received
from or payments made to AMAK are recorded as decreases or increases in the balance of our investment. See Note 10 to the Notes to the
Consolidated Financial Statements.

We assess our investment in AMAK for impairment when events are identified, or there are changes in circumstances that may have an
adverse effect on the fair value of the investment. We consider recoverable ore reserves and the amount and timing of the cash flows to be
generated by the production of those reserves, as well as, recent equity transactions within AMAK. Factors which

39

Table of Contents

may affect carrying value include, but are not limited to, mineral prices, capital cost estimates, equity transactions, the estimated operating
costs of any mines and related processing, ore grade and related metallurgical characteristics, the design of any mines and the timing of any
mineral production. There are no assurances that we will not be required to take a material write-down of any of our mineral properties.

Environmental Liabilities

Our operations are subject to the rules and regulations of the TCEQ which inspects the facilities at various times for possible violations
relating to air, water and industrial solid waste requirements. As noted in Item 1. Business, evidence of groundwater contamination was
discovered at SHR in 1993. The recovery process, initiated in 1998, is proceeding as planned and is expected to continue for many years.
See Note 14 to the Notes to the Consolidated Financial Statements.

Share-Based Compensation

We expense the cost of director and employee services received in exchange for an award of equity instruments based on the grant date fair
value of such instruments. For options we use the Black-Sholes model to calculate the fair value of the equity instrument on the grant date.
See Note 15 to the Notes to the Consolidated Financial Statements.

Off Balance Sheet Arrangements

Off  balance  sheet  arrangements  as  defined  by  the  SEC  means  any  transaction,  agreement  or  other  contractual  arrangement  to  which  an
entity unconsolidated with the registrant is a party, under which the registrant has (i) obligations under certain guarantees or contracts, (ii)
retained  or  contingent  interest  in  assets  transferred  to  an  unconsolidated  entity  or  similar  arrangements,  (iii)  obligations  under  certain
derivative  arrangements,  and  (iv)  obligations  arising  out  of  a  material  variable  interest  in  an  unconsolidated  entity.  Our  guarantee  for
AMAK's  debt  is  considered  an  off  balance  sheet  arrangement. Please  see  further  discussion  under  "Investment  in  AMAK"  in  Item  1.
Business.

Income Taxes

In determining our income tax provision, we assess the likelihood our deferred tax assets will be recovered through future taxable income.
Based on this assessment, a valuation allowance against all or a portion of our deferred tax asset that will, more likely than not, be realized.
If  these  estimates,  assumptions,  or  actual  results  of  operations  change  in  the  future,  we  may  reverse  the  valuation  allowance  against
deferred  tax  assets.  Income  tax  liabilities  are  determined  based  on  judgment  and  estimates  assuming  it  is  more  likely  than  not  that  the
position will be sustained upon examination by a taxing authority. See Note 16 to the Notes to the Consolidated Financial Statements.

On December 22, 2017, Public Law No. 115-97, also known as, the Tax Cuts and Jobs Act ("TCJA") was enacted. The TCJA included a
number of changes to existing U.S. tax laws that impacted the Company, most notably a reduction of the U.S. federal corporate income tax
rate from a maximum of 35% to a flat 21% for tax years effective January 1, 2018. The TCJA also implemented a territorial tax system,
provided  for  a  one-time  deemed  repatriation  tax  on  unrepatriated  foreign  earnings,  eliminated  the  alternative  minimum  tax  ("AMT"),
making AMT  credit  carryforwards  refundable,  and  permits  the  acceleration  of  depreciation  for  certain  assets  placed  into  service  after
September 27, 2017. In addition the TJCA created prospective changes beginning in 2018, including repeal of the domestic manufacturing
deduction,  acceleration  of  tax  revenue  recognition,  capitalization  of  research  and  development  expenditures,  additional  limitations  on
executive compensation and limitations on the deductibility of interest.

The  Company  elected  to  recognize  the  income  tax  effects  of  the  TCJA  in  its  financial  statements  in  accordance  with  Staff Accounting
Bulletin 118 (SAB 118), which provides guidance for the application of ASC Topic 740  Income Taxes, in the reporting period in which the
TCJA  was  signed  into  law.  Under  SAB  118  when  a  Company  does  not  have  the  necessary  information  available,  prepared,  or  analyzed
(including  computations)  in  reasonable  detail  to  complete  the  accounting  for  certain  income  tax  effects  of  the  TCJA  it  will  recognize
provisional amounts if a reasonable estimate can be made. After the analysis, the Company did not identify any items for which the income
tax effects of the TCJA have not been completed and a reasonable estimate could not be determined as of December 31, 2018.

The  changes  to  existing  U.S.  tax  laws  as  a  result  of  the  TCJA,  which  will  have  the  most  significant  impact  on  the  Company's  federal
income taxes are as follows:

Reduction  of  the  U.S.  Corporate  Income  Tax  Rate  -  The  Company  uses  the  asset  and  liability  method  of  accounting  for  income  taxes.
Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the
financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are
measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to
reverse. As a result of the reduction in the U.S. corporate income tax rate from 35% to 21% under the TCJA, the Company revalued its
ending net deferred tax liabilities at December 31, 2017. The reduction in the corporate income tax rate resulted in the Company recording
$10.3 million benefit from deferred taxes in the year ending December 31, 2017.

40

Table of Contents

Acceleration of Depreciation - The Company recognized a reduction to net deferred tax assets attributable to the accelerated depreciation
for  certain  assets  placed  into  service  after  September  27,  2017.  This  adjustment  resulted  in  an  increase  in  income  tax  receivable  of
approximately $961,000 in the year ending December 31, 2017.

Item 7A. Quantitative and Qualitative Disclosures about Market Risk.

The market risk inherent in our financial instruments represents the potential loss resulting from adverse changes in interest rates, foreign
currency  rates  and  commodity  prices.  Our  exposure  to  interest  rate  changes  results  from  our  variable  rate  debt  instruments  which  are
vulnerable to changes in short term United States prime interest rates. At December 31, 2018, 2017 and 2016, we had approximately $103.3
million, $99.6 million and $84.0 million, respectively, in variable rate debt outstanding, excluding deferred financing costs. A hypothetical
10% change in interest rates underlying these borrowings would result in annual changes in our earnings and cash flows of approximately
$433,000, $405,000 and $275,000 at December 31, 2018, 2017 and 2016, respectively.

We  do  not  view  exchange  rates  exposure  as  significant  and  have  not  acquired  or  issued  any  foreign  currency  derivative  financial
instruments.

We purchase all of our raw materials, consisting of feedstock and natural gas, on the open market. The cost of these materials is a function
of  non-formula  market  oil  and  gas  prices. As  a  result,  our  revenues  and  gross  margins  could  be  affected  by  changes  in  the  price  and
availability of feedstock and natural gas. As market conditions dictate, from time to time we engage in various hedging techniques including
financial swap and option agreements. We do not use such financial instruments for trading purposes and are not a party to any leveraged
derivatives. Our policy on such hedges is to buy positions as opportunities present themselves in the market and to hold such positions until
maturity, thereby offsetting the physical purchase and price of the materials.

At the end of 2018, market risk for 2019 was estimated as a hypothetical 10% increase in the cost of natural gas and feedstock over the
market price prevailing on December 31, 2018. Assuming that 2019 total specialty petrochemical product sales volumes stay at the same
rate as 2018, the 10% market risk increase will result in an increase in the cost of natural gas and feedstock of approximately $11.9 million
in fiscal 2019.

The  consolidated  financial  statements  of  the  Company  and  the  consolidated  financial  statement  schedules,  including  the  report  of  our
independent registered public accounting firm thereon, are set forth beginning on Page F-1.

Item 9. Changes In and Disagreements with Accountants on Accounting and Financial Disclosure.

None.
Item 9A. Controls and Procedures.

(a) Disclosure 
Procedures.

Controls 

and

We maintain disclosure controls and procedures (as defined in Rule 13a-15(e) and 15d-15(e)) under the Exchange Act that are designed to
provide reasonable assurance that the information that we are required to disclose in the reports we file or submit under the Exchange Act
is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms, and such information is
accumulated and communicated to our management, including our Chief Executive Office and Chief Financial Officer, as appropriate, to
allow  timely  decisions  regarding  required  disclosure.  It  should  be  noted  that  because  of  inherent  limitations,  our  disclosure  controls  and
procedures,  however  well  designed  and  operated,  can  provide  only  reasonable,  and  not  absolute,  assurance  that  the  objective  of  the
disclosure controls and procedures are met.

As  required  by  paragraph  (b)  of  Rules  13a-15  and  15d-15  under  the  Exchange Act,  our  Chief  Executive  Officer,  and  Chief  Financial
Officer  have  evaluated  the  effectiveness  of  our  disclosure  controls  and  procedures  (as  such  term  is  defined  in  Rules  13a-15(e)  and  15d-
15(e) under the Exchange Act) as of the end of the period covered by this report. Based on such evaluation, our Chief Executive Officer
and Chief Financial Officer have concluded, as of the end of the period covered by this report, that our disclosure controls and procedures
were effective at a reasonable assurance level to ensure that the information that we are required to disclose in the reports we file or submit
under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms and such
information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer as
appropriate, to allow timely decisions regarding required disclosure because of the material weakness in our internal control over financial
reporting described below.

(b) Management's  Annual  Report  on  Internal  Control  over  Financial

Reporting.

Our  management  is  responsible  for  establishing  and  maintaining  adequate  internal  control  over  financial  reporting.  Our  internal  control
over financial reporting is a process that is designed under the supervision of our Chief Executive Officer and Chief Financial Officer, and
effected  by  our  Board  of  Directors,  management  and  other  personnel,  to  provide  assurance  regarding  financial  reporting  and  the
preparation  of  the  financial  statements  for  external  purposes  in  accordance  with  accounting  principles  generally  accepted  in  the  United
States. Our internal control of financial reporting includes those policies and procedures that:

•

Pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of
our assets;

41

Table of Contents

•

•

Provide  reasonable  assurance  that  transactions  are  recorded  as  necessary  to  permit  preparation  of  financial  statements  in
accordance with accounting principles generally accepted in the United States, and that receipts and expenditures recorded by us
are being made only in accordance with authorizations of our management and Board of Directors; and

Provide  reasonable  assurance  regarding  prevention  or  timely  detection  of  unauthorized  acquisition,  use  or  disposition  of  our
assets that could have a material effect on our financial statements.

Internal control over financial reporting has inherent limitations. Internal control over financial reporting is a process that involves human
diligence and compliance and is subject to lapses in judgment and breakdowns resulting from human failures. Internal control over financial
reporting also can be circumvented by collusion or improper management override. Because of such limitations, there is a risk that material
misstatements  will  not  be  prevented  or  detected  on  a  timely  basis  by  internal  control  over  financial  reporting.  However,  these  inherent
limitations are known features of the financial reporting process. Therefore, it is possible to design into the process safeguards to reduce,
though not eliminate, this risk. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may
become inadequate because of changes in conditions, or that the degree of compliance with the policies and procedures may deteriorate.

Management  has  conducted  its  evaluation  of  the  effectiveness  of  our  internal  control  over  financial  reporting  as  of  December  31,  2018,
based  upon  the  framework  in Internal  Control  –  Integrated  Framework (2013)  by  the  Committee  of  Sponsoring  Organizations  of  the
Treadway Commission.  Management's assessment included an evaluation of the design of our internal control over financial reporting and
testing the operating effectiveness of our internal control over financial reporting.  Management reviewed the results of the assessment with
the Audit Committee of the Board of Directors.  Based on its assessment and review with the Audit Committee, management concluded that
our internal control over financial reporting was effective as of December 31, 2018.

(c) Attestation  Report  of  the  Registered  Public  Accounting

Firm.

BKM Sowan Horan, LLP, an independent registered public accounting firm, has audited the consolidated financial statements included in
this Annual Report on Form 10-K and, as part of their audit, has issued their report, included herein, on the effectiveness of our internal
control over financial reporting.

(d) Changes in Internal Control over Financial Reporting.

There have been no changes in our internal control over financial reporting during the fourth quarter of 2018 that have materially affected,
or  are  reasonable  likely  to  materially  affect,  our  internal  control  over  financial  reporting.  From  time  to  time,  we  make  changes  to  our
internal control over financial reporting that are intended to enhance its effectiveness and which do not have a material effect on our overall
internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and
Stockholders of Trecora Resources

Opinion on Internal Control over Financial Reporting

We have audited Trecora Resources’ (the Company’s) internal control over financial reporting as of December 31, 2018, based on criteria
established  in Internal  Control-Integrated  Framework  (2013)  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway
Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting
as of December 31, 2018, based on criteria established in Internal Control-Integrated Framework (2013) issued by COSO.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the
balance  sheets  and  the  related  statements  of  operations,  stockholders’  equity,  and  cash  flows  of  the  Company,  and  our  report  dated
March 15, 2019, expressed an unqualified opinion.

Basis for Opinion

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

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

Definition and Limitations of Internal Control over Financial Reporting

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

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

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and
Stockholders of Trecora Resources

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Trecora Resources and Subsidiaries (the Company) as of December 31,
2018 and 2017, and the related consolidated statements of income, comprehensive income, stockholders’ equity and cash flows for each of
the  years  in  the  three–year  period  ended  December  31,  2018  and  the  related  notes  and  schedules  listed  in  the  index  at  Item  15(a)
(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
years in the three-year period ended December 31, 2018, in conformity with accounting principles generally accepted in the United States
of America.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the
Company’s internal control over financial reporting as of December 31, 2018, based on criteria established in Internal Control—Integrated
Framework (2013)  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission  (COSO),  and  our  report  dated
March 15, 2019, expressed an unqualified opinion.

Basis for Opinion

These  financial  statements  are  the  responsibility  of  the  Company’s  management.  Our  responsibility  is  to  express  an  opinion  on  the
Company’s financial statements based on our audits. We are a public accounting firm registered with the 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 financial statements are free of material misstatement, whether due to error or fraud. Our
audits included performing procedures to assess the risks of material misstatement of the 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  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  financial  statements.  We  believe  that  our  audits
provide a reasonable basis for our opinion.

/s/ BKM Sowan Horan, LLP

We have served as the Company’s auditor since 2010.

NOTE 1 - BUSINESS AND OPERATIONS OF THE COMPANY

Trecora  Resources,  formerly Arabian American  Development  Company,  (the  "Company")  was  organized  as  a  Delaware  corporation  in
1967. The Company's principal business activities are the manufacturing of various specialty petrochemical products, specialty waxes and
providing  custom  processing  services.  The  Company  owns 33%  of  a  Saudi Arabian  joint  stock  company, Al  Masane Al  Kobra  Mining
Company ("AMAK") (see Note 10) and approximately 55% of the capital stock of a Nevada mining company, Pioche Ely Valley Mines,
Inc. ("PEVM"), which does not conduct any substantial business activity but owns undeveloped properties in the United States.

The Company's specialty petrochemical operations are primarily conducted through a wholly-owned subsidiary, Texas Oil and Chemical
Co.  II,  Inc.  ("TOCCO").  TOCCO  owns  all  of  the  capital  stock  of  South  Hampton  Resources,  Inc.  ("SHR")  and  Trecora  Chemical,  Inc.
("TC").  SHR  owns  all  of  the  capital  stock  of  Gulf  State  Pipe  Line  Company,  Inc.  ("GSPL").  SHR  owns  and  operates  a  specialty
petrochemical  product  facility  near  Silsbee,  Texas  which  manufactures  high  purity  hydrocarbons  used  primarily  in  polyethylene,
packaging, polypropylene, expandable polystyrene, poly-iso/urethane foams, Canadian tar sands, and in the catalyst support industry. TC
owns  and  operates  a  facility  located  in  Pasadena,  Texas  which  manufactures  specialty  waxes  and  provides  custom  processing  services.
These specialty waxes are used in the production of coatings, hot melt adhesives and lubricants. GSPL owns and operates pipelines that
connect the SHR facility to a natural gas line, to SHR's truck and rail loading terminal and to a major petroleum pipeline owned by an
unaffiliated third party.

We attribute revenues to countries based upon the origination of the transaction. All of our revenues for the years ended  December  31,
2018, 2017, and 2016, originated in the United States. In addition, all of our long-lived assets are in the United States.

For convenience in this report, the terms "Company", "our", "us" or "we" may be used to refer to Trecora Resources and its subsidiaries.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles  of  Consolidation  –  The  consolidated  financial  statements  include  the  balance  sheets,  statements  of  income,  stockholders'
equity, and cash flows of the Company, TOCCO, TC, SHR, GSPL and PEVM. Other entities which are not controlled but over which the
Company has the ability to exercise significant influence such as AMAK, are accounted for using the equity method of accounting. All
intercompany profits, transactions and balances have been eliminated.

Cash,  Cash  Equivalents  and  Short-Term  Investments   –  Our  principal  banking  and  short-term  investing  activities  are  with  local  and
national financial institutions. Short-term investments with an original maturity of three months or less are classified as cash equivalents.

Inventories – Finished products and feedstock are recorded at the lower of cost, determined on the first-in, first-out method (FIFO), or
market  for  SHR.  For  TC,  inventory  is  recorded  at  the  lower  of  cost  or  market  as  follows:  (1)  raw  material  cost  is  calculated  using  the
weighted-average cost method and (2) product inventory cost is calculated using the specific cost method.

Trade Receivables and Allowance for Doubtful Accounts  – We evaluate the collectability of our trade receivables and adequacy of the
allowance  for  doubtful  accounts  based  upon  historical  experience  and  any  specific  customer  financial  difficulties  of  which  we  become
aware.  For  the  year  ended  December  31,  2018,  we  increased  the  balance  by $152,000  due  to  concerns  regarding  collectability  for  a
specific customer. For the year ended December 31, 2017, the allowance balance was not increased. In 2016, we increased the balance by
$90,000 due to an increase in sales in countries where there is a greater risk of default and limited recourse should this occur. We track
customer  balances  and  past  due  amounts  to  determine  if  customers  may  be  having  financial  difficulties.  This,  along  with  historical
experience and a working knowledge of each customer, helps determine accounts that should be written off. No amounts were written off
in 2018 or 2017. During 2016 we wrote off one account for approximately $93,000.

Notes Receivable – We periodically make changes in or expand our custom processing units at the request of the customer. The cost to
make these changes is shared by the customer. Upon completion of a project a non-interest note receivable is recorded with an imputed
interest  rate.  There  were  no  notes  receivable  outstanding  as  of  December  31,  2018.  The  interest  rate  used  on  outstanding  notes  during
December 31, 2018 and 2017 was 4%. The unearned interest was reflected as a discount against the note balance. The Company evaluates
the collectability of notes based upon a working knowledge of the customer. The notes are receivable from custom processing customers
with whom we maintain a close relationship. Thus, all amounts due under the notes receivable are considered collectible, and no allowance
was recorded at December 31, 2018 and 2017, respectively.

Plant, Pipeline and Equipment  –  Plant,  pipeline  and  equipment  are  stated  at  cost.  Depreciation  is  provided  over  the  estimated  service
lives using the straight-line method. Gains and losses from disposition are included in operations in the period incurred. Maintenance and
repairs are expensed as incurred. Major renewals and improvements are capitalized.

F-10

Table of Contents

Interest costs incurred to finance expenditures during construction phase are capitalized as part of the historical cost of constructing the
assets. Construction commences with the development of the design and ends when the assets are ready for use. Capitalized interest costs
are included in plant, pipeline and equipment and are depreciated over the service life of the related assets.

Labor  costs  incurred  to  self-construct  assets  are  capitalized  as  part  of  the  historical  cost  the  assets.  Construction  commences  with  the
development  of  the  design  and  ends  when  the  assets  are  ready  for  use.  Capitalized  labor  costs  are  included  in  plant,  pipeline  and
equipment and are depreciated over the service life of the related assets.

Platinum  catalyst  is  included  in  plant,  pipeline  and  equipment  at  cost. Amortization  of  the  catalyst  is  based  upon  cost  less  estimated
salvage value of the catalyst using the straight line method over the estimated useful life (see Note 8).

Goodwill  and  Other  Intangible Assets   –  Goodwill  represents  the  future  economic  benefits  arising  from  other  assets  acquired  in  the
acquisition of TC that are not individually identified and separately recognized. Goodwill and indefinite-lived intangible assets are tested
for  impairment  at  least  annually;  however,  these  tests  are  performed  more  frequently  when  events  or  changes  in  circumstances  indicate
that the asset may be impaired. Impairment exists when carrying value exceeds fair value. Estimates of fair value are based on appraisals,
market prices for comparable assets, or internal estimates of future net cash flows.

Definite-lived intangible assets consist of customer relationships, licenses, permits and developed technology that were acquired as part of
the Acquisition of TC. The majority of these assets are being amortized using discounted estimated future cash flows over the term of the
related  agreements.  Intangible  assets  associated  with  customer  relationships  are  being  amortized  using  the  discounted  estimated  future
cash flows method based upon assumed rates of annual customer attrition. We continually evaluate the reasonableness of the useful lives
of these assets. Once these assets are fully amortized, they will be removed from the consolidated balance sheets.

Business  Combinations  and  Related  Business  Acquisition  Costs  –  Assets  and  liabilities  associated  with  business  acquisitions  are
recorded at fair value using the acquisition method of accounting. We allocate the purchase price of acquisitions based upon the fair value
of  each  component  which  may  be  derived  from  various  observable  and  unobservable  inputs  and  assumptions.  We  may  use  third-party
valuation  specialists  to  assist  us  in  this  allocation.  Initial  purchase  price  allocations  are  preliminary  and  subject  to  revision  within  the
measurement period, not to exceed one year from the date of acquisition. The fair value of property, plant and equipment and intangible
assets  are  based  upon  the  discounted  cash  flow  method  that  involves  inputs  that  are  not  observable  in  the  market  (Level  3).  Goodwill
assigned represents the amount of consideration transferred in excess of the fair value assigned to identifiable assets acquired and liabilities
assumed.

Business acquisition costs are expensed as incurred and are reported as general and administrative expenses in the consolidated statements
of income. We define these costs to include finder's fees, advisory, legal, accounting, valuation, and other professional consulting fees, as
well as, travel associated with the evaluation and effort to acquire specific businesses.

Investment  in AMAK  –  We  account  for  our  investment  in AMAK  using  the  equity  method  of  accounting  under  which  we  record  in
income our share of AMAK's income or loss for each period. The amount recorded is also adjusted to reflect the amortization of certain
differences  between  the  basis  in  our  investment  in AMAK  and  our  share  of  the  net  assets  of AMAK  as  reflected  in AMAK's  financial
statements (see Note 10). Any proceeds received from or payments made to AMAK are recorded as decreases or increases in the balance
of our investment.

We assess our investment in AMAK for impairment when events are identified, or there are changes in circumstances that may have an
adverse effect on the fair value of the investment. We consider recoverable ore reserves, changes in commodity prices, and the amount and
timing of the cash flows to be generated by the production of those reserves, as well as, recent equity transactions within AMAK.

Other Assets   –  Other  assets  include  a  license  used  in  specialty  petrochemical  operations,  spare  parts  inventory  and  certain  specialty
petrochemical assets. Beginning January 1, 2017, due to the expansion of our plant assets at SHR and TC, we began inventorying spare
parts for the repair and maintenance of our plant, pipeline and equipment. Spare parts are accounted for on the first-in, first-out method
(FIFO).

Long-Lived Assets Impairment  – Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate
that  the  carrying  amount  may  not  be  recoverable  based  on  the  undiscounted  net  cash  flows  to  be  generated  from  the  asset's  use.  The
amount  of  the  impairment  loss  to  be  recorded  is  calculated  by  the  excess  of  the  asset's  carrying  value  over  its  fair  value.  Fair  value  is
generally determined using a discounted cash flow analysis although other factors including the state of the economy are considered.

Revenue  Recognition –  The  Company  adopted  Financial  Accounting  Standards  Board  ("FASB")  Accounting  Standards  Codification
("ASC")  Topic  606  ("ASC  606"), Revenue from Contracts with Customers, and its amendments with  a  date  of  the  initial  application  of
January 1, 2018. As a result, the Company has changed its accounting policy for revenue recognition as detailed below. ASC 606 outlines
a  single  comprehensive  model  for  an  entity  to  use  in  accounting  for  revenue  arising  from  all  contracts  with  customers,  except  where
revenues are in scope of another accounting standard. ASC 606 superseded the revenue

F-11

Table of Contents

recognition requirements in ASC Topic 605, "Revenue Recognition", and most industry specific guidance. ASC Topic 606 sets forth a five-
step model for determining when and how revenue is recognized. Under the model, an entity is required to recognize revenue to depict the
transfer of goods or services to a customer at an amount reflecting the consideration it expects to receive in exchange for those goods and
services. ASC 606 also requires certain additional revenue-related disclosures.

The  Company  applied  the  modified  retrospective  approach  under ASC  606  which  allows  for  the  cumulative  effect  of  adopting  the  new
guidance on the date of initial application. Use of the modified retrospective approach means the Company's comparative periods prior to
initial application are not restated. The initial application was applied to all contracts at the date of the initial application.   The Company
has  determined  that  the  adjustments  using  the  modified  retrospective  approach  did  not  have  a  material  impact  on  the  date  of  the  initial
application along with the disclosure of the effect on prior periods.

Accounting Policy

Beginning  on  January  1,  2018,  revenue  is  measured  based  on  a  consideration  specified  in  a  contract  with  a  customer.  The  Company
recognizes revenue when it satisfies a performance obligation by transferring control over a product or service to a customer. In evaluating
when  a  customer  has  control  of  the  asset  we  primarily  consider  whether  the  transfer  of  legal  title  and  physical  delivery  has  occurred,
whether  the  customer  has  significant  risks  and  rewards  of  ownership,  and  whether  the  customer  has  accepted  delivery  and  a  right  to
payment exists. Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing
transaction, that are collected by the Company from a customer, are excluded from revenue. Shipping and handling costs associated with
outbound freight after control over a product has transferred to a customer are accounted for as a fulfillment cost and are included in cost of
product sales and processing. The Company does not offer material rights of return or service-type warranties.

For  the  year  ended  December  31,  2017  the  Company  recognized  revenue  according  to  FASB ASC  Topic  605  ("ASC  605"),  " Revenue
Recognition", when: (1) the customer accepted delivery of the product and title had been transferred or when the service was performed
and the Company had no significant obligations remaining to be performed; (2) a final understanding as to specific nature and terms of the
agreed upon transaction had occurred; (3) price was fixed and determinable; and (4) collection was assured. Product sales generally met
these  criteria,  and  revenue  was  recognized,  when  the  product  was  delivered  or  title  was  transferred  to  the  customer.  Sales  revenue  was
presented  net  of  discounts,  allowances,  and  sales  taxes.  Freight  costs  billed  to  customers  were  recorded  as  a  component  of  revenue.
Revenues  received  in  advance  of  future  sales  of  products  or  prior  to  the  performance  of  services  were  presented  as  deferred  revenues.
Shipping and handling costs were classified as cost of product sales and processing and were expensed as incurred.

Nature of goods and services

The following is a description of principal activities – separated by reportable segments – from which the Company generates its revenue.
For more detailed information about reportable segments, disaggregation of revenues, and contract balance disclosures, see Note 17.

Specialty petrochemical segment

The  specialty  petrochemical  segment  of  the  Company  produces  eight  high  purity  hydrocarbons  and  other  petroleum  based  products
including  isopentane,  normal  pentane,  isohexane  and  hexane.  These  products  are  used  in  the  production  of  polyethylene,  packaging,
polypropylene,  expandable  polystyrene,  poly-iso/urethane  foams,  crude  oil  from  the  Canadian  tar  sands,  and  in  the  catalyst  support
industry. SHR's specialty petrochemical products are typically transported to customers by rail car, tank truck, iso-container and ship.

Product Sales – The Company sells individual (distinct) products to its customers on a stand-alone basis (point-of-sale) without any further
integration. There is no significant modification of any one or more products sold to fulfill another promised product or service within any
of the Company's product sale transactions. The amount of consideration received for product sales is stated within the executed invoice
with the customer. Payment is typically due and collected 30 to 60 days subsequent to point of sale.

Processing  Fees  –  The  Company's  services  consist  of  processing  customer  supplied  feedstocks  into  custom  products  including,  if
requested,  services  for  forming,  packaging,  and  arranging  shipping.  Pursuant  to  Tolling  Agreements  the  customer  retains  title  to  the
feedstocks  and  processed  products.  The  performance  obligation  in  each  Tolling Agreement  transaction  is  the  processing  of  customer
provided  feedstocks  into  custom  products  and  is  satisfied  over  time.      The  amount  of  consideration  received  for  product  sales  is  stated
within the executed invoice with the customer. Payment is typically due and collected within 30 days subsequent to point of sale.

Specialty Wax segment

F-12

Table of Contents

The specialty wax segment of the Company manufactures and sells specialty polyethylene and poly alpha olefin waxes and also provides
custom processing services for customers.

Product Sales – The Company sells individual (distinct) products to its customers on a stand-alone basis (point-of-sale) without any further
integration. There is no significant modification of any one or more products sold to fulfill another promised product or service within any
of the Company's product sale transactions. The amount of consideration received for product sales is stated within the executed invoice
with the customer. Payment is typically due and collected within 30 days subsequent to point of sale.

Processing Fees – The Company's promised services consist of processing customer supplied feedstocks into custom products including, if
requested, services for forming, packaging, and arranging shipping. Pursuant to Tolling Agreements and Purchase Order Arrangements, the
customer  typically  retains  title  to  the  feedstocks  and  processed  products.  The  performance  obligation  in  each  Tolling  Agreement
transaction and Purchase Order Arrangement is the processing of customer provided feedstocks into custom products and is satisfied over
time.      The  amount  of  consideration  received  for  product  sales  is  stated  within  the  executed  invoice  with  the  customer.  Payment  is
typically due and collected within 30 days subsequent to point of sale.

Shipping and Handling Costs – Shipping and handling costs are classified as cost of product sales and processing and are expensed as
incurred.

Retirement Plan  –  We  offer  employees  the  benefit  of  participating  in  a  401(k)  plan.  We  match  100%  up  to 6%  of  pay  with  vesting
occurring  over 2  years.  For  years  ended December  31,  2018,  2017,  and 2016,  matching  contributions  of  approximately $1,502,000,
$1,412,000, and $1,195,000, respectively were made on behalf of employees.

Environmental Liabilities – Remediation costs are accrued based on estimates of known environmental remediation exposure. Ongoing
environmental compliance costs, including maintenance and monitoring costs, are expensed as incurred.

Other Liabilities – We periodically make changes in or expand our custom processing units at the request of the customer. The cost to
make  these  changes  is  shared  by  the  customer.  Upon  completion  of  a  project  a  note  receivable  and  a  deferred  liability  are  recorded  to
recover the project costs which are then capitalized. At times instead of a note receivable being established, the customer pays an upfront
cost. The amortization of other liabilities is recorded as a reduction to depreciation expense over the life of the contract with the customer.
As  of  December  31  of  each  year,  depreciation  expense  was  offset  and  reduced  by  approximately $0.8 million,  $0.8  million,  and $1.0
million, for 2018, 2017, and 2016, respectively.

Net  Income  Per  Share  –  We  compute  basic  income  per  common  share  based  on  the  weighted-average  number  of  common  shares
outstanding. Diluted income per common share is computed based on the weighted-average number of common shares outstanding plus
the  number  of  additional  common  shares  that  would  have  been  outstanding  if  potential  dilutive  common  shares,  consisting  of  stock
options, unvested restricted stock units, and shares which could be issued upon conversion of debt, had been issued (see Note 18).

Foreign  Currency  –  The  functional  currency  for  the  Company  and  each  of  the  Company's  subsidiaries  is  the  US  dollar  (USD).
Transaction  gains  or  losses  as  a  result  of  transactions  denominated  and  settled  in  currencies  other  than  the  USD  are  reflected  in  the
statements of income as foreign exchange transaction gains or losses. We do not employ any practices to minimize foreign currency risks.
The functional and reporting currency of AMAK is the Saudi Riyal (SR). In June 1986 the SR was officially pegged to the USD at a fixed
exchange rate of 1 USD to 3.75 SR; therefore, we translate SR into our reporting currency of the USD for income statement and balance
sheet purposes using the fixed exchange rate. As of December 31, 2018, 2017 and 2016, foreign currency translation adjustments were not
significant.

Management  Estimates  –  The  preparation  of  consolidated  financial  statements  in  conformity  with  accounting  principles  generally
accepted  in  the  United  States  of America  requires  management  to  make  estimates  and  assumptions  that  affect  the  reported  amounts  of
assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported
amounts of revenues and expenses during the reporting periods. Significant estimates include allowance for doubtful accounts receivable
and  inventory  obsolescence;  assessment  of  impairment  of  our  long-lived  assets,  goodwill,  intangible  assets  and  investments,  litigation
liabilities,  post-retirement  benefit  obligations,  guarantee  obligations,  environmental  liabilities,  income  taxes  and  deferred  tax  valuation
allowances. Actual results could differ from these estimates.

Share-Based Compensation – We recognize share-based compensation of stock options granted based upon the fair value of options on
the grant date using the Black-Scholes pricing model (see Note 15). Share-based compensation expense recognized during the period is
based  on  the  fair  value  of  the  portion  of  share-based  payments  awards  that  is  ultimately  expected  to  vest.  Share-based  compensation
expense  recognized  in  the  consolidated  statements  of  operations  for  the  years  ended December  31,  2018,  2017,  and 2016  includes
compensation  expense  based  on  the  estimated  grant  date  fair  value  for  awards  that  are  ultimately  expected  to  vest,  and  accordingly  has
been reduced for estimated forfeitures. Estimated forfeitures at the time of grant are revised, if necessary, in subsequent periods if actual
forfeitures differ from those estimates.

F-13

Table of Contents

Guarantees  –  We  may  enter  into  agreements  which  contain  features  that  meet  the  definition  of  a  guarantee  under  FASB  ASC  460
"Guarantees" (see Note 14). These arrangements create two types of obligations:

a) We have a non-contingent and immediate obligation to stand ready to make payments if certain future triggering events occur. For

certain guarantees, a liability is recognized for the stand ready obligation at the inception of the guarantee; and

b)We have an obligation to make future payments if those certain future triggering events do occur. A liability for the payment

under the guarantee is recognized when 1) it becomes probable that one or more future events will occur, triggering the
requirement to make payments under the guarantee and 2) when the payment can be reasonably estimated.

Fair Value – The carrying value of cash and cash equivalents, trade receivables, taxes receivable, accounts payable, accrued liabilities, and
other  liabilities  approximate  fair  value  due  to  the  immediate  or  short-term  maturity  of  these  financial  instruments.  The  fair  value  of
variable rate long term debt and notes payable reflect recent market transactions and approximate carrying value. We used other observable
inputs that would qualify as Level 2 inputs to make our assessment of the approximate fair value of our cash and cash equivalents, trade
receivables, taxes receivable, accounts payable, accrued liabilities, other liabilities, notes payable and variable rate long term debt. The fair
value of the derivative instruments are described below.

We measure fair value by ASC Topic 820 Fair Value. ASC Topic 820 defines fair value, establishes a framework for measuring fair value,
and expands disclosures about fair value measurements. ASC Topic 820 applies to reported balances that are required or permitted to be
measured  at  fair  value  under  existing  accounting  pronouncements;  accordingly,  the  standard  amends  numerous  accounting
pronouncements but does not require any new fair value measurements of reported balances. ASC Topic 820 emphasizes that fair value,
among  other  things,  is  based  on  exit  price  versus  entry  price,  should  include  assumptions  about  risk  such  as  nonperformance  risk  in
liability  fair  values,  and  is  a  market-based  measurement,  not  an  entity-specific  measurement.  When  considering  the  assumptions  that
market participants would use in pricing the asset or liability, ASC Topic 820 establishes a fair value hierarchy that distinguishes between
market participant assumptions based on market data obtained from sources independent of the reporting entity (observable inputs that are
classified  within  Levels  1  and  2  of  the  hierarchy)  and  the  reporting  entity's  own  assumptions  about  market  participant  assumptions
(unobservable inputs classified within Level 3 of the hierarchy). The fair value hierarchy prioritizes inputs used to measure fair value into
three broad levels.

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

Derivatives – We record derivative instruments as either an asset or liability measured at fair value. Changes in the derivative instrument's
fair value are recognized currently in earnings unless specific hedge accounting criteria are met. Special accounting for qualifying hedges
allows a derivative instrument's gains and losses to offset related results on the hedged item in the income statement, to the extent effective,
and requires that a company must formally document, designate and assess the effectiveness of transactions that receive hedge accounting.

Income Taxes – Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the
financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are
measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be
recovered  or  settled.  The  effect  on  deferred  tax  assets  and  liabilities  of  a  change  in  tax  rates  is  recognized  in  income  in  the  period  that
includes the enactment date. The Company maintains a valuation allowance for a deferred tax asset when it is deemed to be more likely
than not that some or all of the deferred tax asset will not be realized.

Our  estimate  of  the  potential  outcome  of  any  uncertain  tax  issues  is  subject  to  management's  assessment  of  relevant  risks,  facts,  and
circumstances existing at that time. We use a more likely than not threshold for financial statement recognition and measurement of tax
position  taken  or  expected  to  be  taken  in  a  tax  return.  To  the  extent  that  our  assessment  of  such  tax  position  changes,  the  change  in
estimate  is  recorded  in  the  period  in  which  the  determination  is  made.  We  report  tax-related  interest  and  penalties  as  a  component  of
income tax expense.

On December 22, 2017, Public Law No. 115-97 known as the Tax Cuts and Jobs Act (TCJA) was enacted. The TCJA included a number
of changes to existing U.S. tax laws that impact the Company, most notably a reduction of the U.S. federal corporate income tax rate from
a maximum of 35 percent to a flat 21 percent for tax years effective January 1, 2018. The TCJA also implemented a territorial tax system,
provided for a one-time deemed repatriation tax on unrepatriated foreign earnings, eliminated the alternative minimum tax (AMT), made
AMT credit carryforwards refundable, and permitted the acceleration of depreciation for certain assets placed into service after September
27, 2017. In addition the TJCA created prospective changes beginning in 2018, including repeal of the domestic manufacturing deduction,
acceleration of tax revenue recognition,

F-14

Table of Contents

capitalization  of  research  and  development  expenditures,  additional  limitations  on  executive  compensation  and  limitations  on  the
deductibility of interest.

The Company has elected to recognize the income tax effects of the TCJA in its financial statements in accordance with Staff Accounting
Bulletin 118 (SAB 118), which provides guidance for the application of ASC Topic 740 Income Taxes, in the reporting period in which the
TCJA was signed into law. Under SAB 118 when a Company does not have the necessary information available, prepared, or analyzed
(including  computations)  in  reasonable  detail  to  complete  the  accounting  for  certain  income  tax  effects  of  the  TCJA  it  will  recognize
provisional amounts if a reasonable estimate can be made. If a reasonable estimate cannot be made then no impact is recognized for the
effect of the TCJA. SAB 118 permits an up to one year measurement period to finalize the measurement of the impact of the TCJA.

Reclassifications – Certain reclassifications have been made to prior year balances to conform with the current year presentation.

Subsequent Events  –  The  Company  has  evaluated  subsequent  events  through March 15, 2019,  the  date  that  the  consolidated  financial
statements were approved by management.

New Accounting Pronouncements

In May 2014 the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-9,  Revenue from
Contracts with Customers ("ASU 2014-9"). ASU 2014-9 supersedes the revenue recognition requirements of FASB Accounting Standards
Codification  ("ASC")  Topic  605, Revenue  Recognition  and  most  industry-specific  guidance  throughout  the  Accounting  Standards
Codification, resulting in the creation of FASB ASC Topic 606,  Revenue from Contracts with Customers. ASU 2014-9 requires entities to
recognize revenue in a way that depicts the transfer of promised goods or services to customers in an amount that reflects the consideration
to  which  the  entity  expects  to  be  entitled  to  in  exchange  for  those  goods  or  services.  This  ASU  provides  alternative  methods  of
retrospective adoption and is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017. The
Company  completed  its  assessment  of  the  impact  of  the  adoption  of ASU  2014-9  across  all  revenue  streams.  This  included  reviewing
current accounting policies and practices to identify potential differences that would result from applying the requirements under the new
standard. We completed contract reviews and validated results of applying the new revenue guidance (Note 2). See Revenue Recognition
policy note.

In  February  2016,  the  FASB  issued ASU  No.  2016-02,  Leases  (Topic  842).  This  update  will  increase  transparency  and  comparability
among  organizations  by  recognizing  lease  assets  and  lease  liabilities  on  the  balance  sheet  and  disclosing  key  information  about  leasing
arrangements.  This  update  is  effective  for  annual  and  interim  reporting  periods  beginning  after  December  15,  2018,  including  interim
periods within those fiscal years. Early adoption is permitted. In July 2018, the FASB issued ASU No. 2018-11, Targeted Improvements to
ASC 842, Leases.  ASU 2018-11 provided entities with an alternative modified transition method to elect not to recast the comparative
periods  presented  when  adopting  ASC  842.  The  new  standard  provides  a  number  of  optional  practical  expedients  in  transition.  The
Company  expects  to  elect:  (1)  the  ‘package  of  practical  expedients’,  which  permits  it  not  to  reassess  under  the  new  standard  its  prior
conclusions  about  lease  identification,  lease  classification,  and  initial  direct  costs  and  (2)  the  use-of-hindsight.  In  addition,  the  new
standard provides practical expedients for an entity’s ongoing accounting that the Company anticipates making, such as the (1) the election
for certain classes of underlying asset to not separate non-lease components from lease components and (2) the election for short-term lease
recognition exemption for all leases that qualify. The Company will adopt ASU 842 as of January 1, 2019, using the alternative modified
transition  method.  In  preparation  of  adopting  ASC  842,  the  Company  is  implementing  additional  internal  controls  to  enable  future
preparation  of  financial  information  in  accordance  with ASC  842.  The  Company  has  also  substantially  completed  its  evaluation  of  the
impact  on  the  Company’s  lease  portfolio.  The  Company  believes  the  largest  impact  will  be  on  the  consolidated  balance  sheets  for  the
accounting  of  rail  cars,  equipment  and  office  leases,  which  represents  a  majority  of  its  operating  leases  it  has  entered  into  as  a  lessee.
These leases will be recognized under the new standard as right of use assets (“ROU”) operating lease liabilities. The Company will also
be required to provide expanded disclosures for its leasing arrangements. As of December 31, 2018, the Company had approximately $18.1
million  of  undiscounted  future  minimum  operating  lease  commitments  that  are  not  recognized  on  its  consolidated  balance  sheets  as
determined under the current standard. For a lessee, the results of operations are not expected to significantly change after adoption of the
new standard.  While substantially complete, the Company is still in the process of finalizing its evaluation of the effect of ASU 842 on the
Company’s financial statements and disclosures, including the determination of the Company’s incremental borrowing rate for each of the
operating leases to estimate the interest rate we would have to pay to borrow on a collateralized basis over a similar term for an amount
equal to the lease payments. The Company will finalize its accounting assessment and quantitative impact of the adoption during the first
quarter of fiscal year 2019.

In  January  2017  the  FASB  issued ASU  No.  2017-4,  Intangibles  –  Goodwill  and  Other  (Topic  350) .  The  amendments  in ASU  2017-4
simplify  the  measurement  of  goodwill  by  eliminating  Step  2  from  the  goodwill  impairment  test.  Instead,  under  these  amendments,  an
entity  should  perform  its  annual,  or  interim,  goodwill  impairment  test  by  comparing  the  fair  value  of  a  reporting  unit  with  its  carrying
amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair
value; however, the loss should not exceed the total amount of goodwill allocated to that reporting

F-15

Table of Contents

unit. The amendments are effective for public business entities for the first interim and annual reporting periods beginning after December
15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017.The
amendments  also  eliminate  the  requirements  for  any  reporting  unit  with  a  zero  or  negative  carrying  amount  to  perform  a  qualitative
assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. An entity still has the option to perform
the  qualitative  assessment  for  a  reporting  unit  to  determine  if  the  quantitative  impairment  test  is  necessary.  The  Company  has  goodwill
from prior business combination and performs an annual impairment test or more frequently if changes or circumstances occur that would
more-likely-than-not reduce the fair value of the reporting unit below its carrying value. During the year ended December 31, 2018, the
Company performed its impairment assessment and determined the fair value of the aggregated reporting units exceed the carrying value,
such  that  the  Company's  goodwill  was  not  considered  impaired. Although  the  Company  cannot  anticipate  future  goodwill  impairment
assessments, based on the most recent assessment, it is unlikely that an impairment amount would need to be calculated and, therefore, the
Company does not anticipate a material impact from these amendments to the Company's financial position and results of operations. The
current accounting policies and processes are not anticipated to change, except for the elimination of the Step 2 analysis.

In February 2018 the FASB issued ASU No. 2018-2,  Income Statement — Reporting Comprehensive Income (Topic 220): Reclassification
of  Certain  Tax  Effects  from  Accumulated  Other  Comprehensive  Income. ASU  2018-2  was  issued  to  address  the  income  tax  accounting
treatment of the stranded tax effects within other comprehensive income due to the prohibition of backward tracing due to an income tax
rate  change  that  was  initially  recorded  in  other  comprehensive  income  due  to  the  enactment  of  the  Tax  Cuts  and  Jobs Act  (TCJA)  on
December 22, 2017, which changed the Company's income tax rate from 35% to 21%. The amendments to the ASU changed US GAAP
whereby an entity may elect to reclassify the stranded tax effect from accumulated other comprehensive income to retained earnings. The
amendments of the ASU may be adopted in total or in part using a full retrospective or modified retrospective method. The amendments of
the ASU  are  effective  for  periods  beginning  after  December  15,  2018.  The  Company  believes  there  will  be  no  material  impact  to  the
consolidated financial statements as a result of this update.

In  June  2018,  the  FASB  issued ASU  No.  2018–07,  Improvements  to  Nonemployee  Share–Based  Payment  Accounting. ASU  2018–07
simplifies  the  accounting  for  share–based  payments  to  nonemployees  by  aligning  it  with  the  accounting  for  share–based  payments  to
employees,  with  certain  exceptions.  The  amendments  in  this ASU  are  effective  for  public  companies  for  fiscal  years  beginning  after
December  15,  2018,  including  interim  periods  within  that  fiscal  year.  The  Company  is  assessing  the  effect  of  ASU  2018–02  on  its
consolidated financial statements.

NOTE 3 – ACQUISITION OF B PLANT

On May 2, 2016, we purchased the idle BASF facility adjacent to our TC facility in exchange for $2.0 million in cash, transaction costs of
approximately $11,000 plus an earnout provision calculated through calendar year 2020 based upon revenue generated by the facility but
limited to $1.8 million. The cash payment was funded by working capital. The purchased facility includes production equipment similar to
TC's  plus  equipment  that  broadens  TC's  capabilities  and  potential  markets.  The 6.5-acre  site  also  includes  substantial  storage  capacity,
several rail and truck loading sites and utility tie-ins to TC. We refer to the facility as "B Plant".

We  have  accounted  for  the  purchase  in  accordance  with  the  acquisition  method  of  accounting  under  Financial Accounting  Standards
Board Accounting Standards Codification Topic 805 "Business Combinations" ("ASC 805"). In accordance with ASC 805, we used our
best estimates and assumptions to assign fair value to the tangible assets and liabilities acquired at the acquisition date.

The assets and liabilities acquired have been included in our consolidated balance sheets and our consolidated statements of income since
the date of acquisition.

We recorded an $11.5 million bargain purchase gain on the transaction as calculated in the table below (in thousands).

The business acquired had been idle for the periods presented thus proforma financial presentation would be identical to our consolidated
results. We began operating the new facility in June 2016.

NOTE 4 - CONCENTRATIONS OF REVENUES AND CREDIT RISK

We sell our products and services to companies in the chemical, plastics, and petroleum industries. We perform periodic credit evaluations
of  our  customers  and  generally  do  not  require  collateral  from  our  customers.  For  the  year  ended December  31,  2018,  one  customer
accounted  for 17.0%  of  consolidated  product  revenue.  For  the  year  ended  December  31,  2017, one  customer  accounted  for 19.6%  of
consolidated  product  revenue.  For  the  year  ended December  31,  2016,  one  customer  accounted  for 20.1%  of  consolidated  product
revenue. The associated accounts receivable balances for those customers were approximately $11.0 million  at December 31, 2018,  and
$5.8 million at December 31, 2017. The carrying amount of accounts receivable approximates fair value at  December 31, 2018, and 2017.

Accounts receivable serves as collateral for our amended and restated loan agreement (see Note 12).

We market our products in many foreign jurisdictions. For the years ended  December 31, 2018, 2017  and 2016, specialty petrochemical
product  sales  revenue  in  foreign  jurisdictions  accounted  for  approximately 35.4%,  20.8%,  and 23.5%  of  total  product  sales  revenue,
respectively.

SHR utilizes one major supplier for its feedstock supply. The feedstock is a commodity product commonly available from other suppliers
if  needed.  The  percentage  of  feedstock  purchased  from  the  supplier  during 2018,  2017,  and 2016  was 100%,  100.0%  and 99%,
respectively.  At  December  31,  2018,  and 2017,  we  owed  the  supplier  approximately $4.7  million  and $8.5  million,  respectively  for
feedstock purchases.

We hold our cash with various financial institutions that are insured by the Federal Deposit Insurance Corporation up to $250,000. At times
during  the  year,  cash  balances  may  exceed  this  limit.  We  have  not  experienced  any  losses  in  such  accounts  and  do  not  believe  we  are
exposed to any significant risk of loss related to cash.

NOTE 10 - INVESTMENT IN AL MASANE AL KOBRA MINING COMPANY ("AMAK")

We  have  concluded  that  we  have  significant  influence  over  the  operating  and  financial  policies  of  AMAK  and,  accordingly,  should
account  for  our  investment  in AMAK  using  the  equity  method. As  of  December  31,  2018,  and 2017,  we  had  a  non-controlling  equity
interest of approximately $38.7 million and $45.1 million, respectively.

We  have  received  and  attached  to  this  Form  10-K  the  financial  statements  of AMAK  prepared  in  accordance  with  generally  accepted
accounting principles in the United States of America as of December 31, 2018, and 2017, and for each of the three

years ended December 31, 2018. These financial statements have been prepared in the functional currency of AMAK which is the Saudi
Riyal (SR). In June 1986 the SR was officially pegged to the U.S. Dollar (USD) at a fixed exchange rate of 1 USD to 3.75 SR.

In  2016  the  difference  between  our  effective  share  of  income  (loss)  from  our  investment  and  our  actual  ownership  percentage  is
attributable to the change in our ownership percentage during the third quarter of 2016.

A gain of approximately  $16.2 million for the difference between our initial investment in AMAK and our share of AMAK's initial assets
recorded at fair value was not recognized in 2008. This basis difference is being amortized over the life of AMAK's

mine which is estimated to be twelve years beginning with its commencement of production in July 2012 as an adjustment to our equity in
AMAK's income or loss.

In July 2016 AMAK issued four million shares to provide additional funds for ongoing exploration work and mine start-up activities. Arab
Mining Co. ("Armico") purchased 3.75 million shares at SR 20 per share (USD 5.33 per share) and the remaining 250,000 shares are for
future use as employee incentives. We did not participate in the offering, thereby reducing our ownership percentage in AMAK to  33.44%
from 35.25%. As  a  result  of  the  equity  issuance,  our  share  of  the  net  assets  of AMAK  increased  approximately  $3.2 million  which  we
recognized as a gain (with a corresponding increase in our investment) in accordance with ASC 323-10-40-1.

In 2018, we completed an exchange of shares with certain shareholders whereby such shareholders traded 65,000 common shares of TREC
in exchange for 24,489 shares of our AMAK stock.  The 65,000 shares were accounted for as treasury stock.  This transaction reduced our
ownership percentage from 33.44% to 33.41%.

As previously announced, AMAK initiated a share repurchase program from its existing shareholders in December 2018. We participated
in  this  share  repurchase  and  received  approximately $5.3  million  in  proceeds  from  AMAK.  We  had  previously  reported,  based  on
information available at the time, that AMAK was repurchasing  10% of its outstanding shares from its existing shareholders on a pro-rata
basis. We have since learned that, while a redemption of up to 10% of AMAK's 82 million outstanding shares had been approved by the
shareholders,  the  repurchase  program  approved  by AMAK's  board  of  directors  and  initiated  in  December  2018  was  with  respect  to 2.5
million  shares. AMAK  expects  to  complete  the  share  repurchase  program  in  2019,  at  which  point  all  shares  repurchased  from AMAK
shareholders will be registered as treasury shares. Upon completion of the share repurchase program, the Company does not believe its
ownership percentage in AMAK will change from 33.4%.

At December  31,  2018  and  2017,  we  had  a  receivable  from AMAK  of  approximately $54,000  and $121,000,  respectively,  relating  to
unreimbursed travel and Board expenses which is included in prepaid and other assets.

We assess our investment in AMAK for impairment when events are identified, or there are changes in circumstances that may have an
adverse effect on the fair value or recoverability of the investment. We consider recoverable ore reserves and the amount and timing of the
cash  flows  to  be  generated  by  the  production  of  those  reserves,  as  well  as,  recent  equity  transactions  within AMAK. No  impairment
charges were recorded in 2018, 2017, or 2016.

NOTE 11 - MINERAL PROPERTIES IN THE UNITED STATES

The principal assets of PEVM are an undivided interest in 48 patented and 5 unpatented mining claims totaling approximately 1,500 acres,
and a 300 ton-per-day mill located on the aforementioned properties in the PEVM Mining District in southeast Nevada.  In August 2001
seventy-five unpatented claims were abandoned since they were deemed to have no future value to PEVM.  The properties held by PEVM
have not been commercially operated for approximately 35 years.

NOTE 12 - LONG-TERM DEBT AND LONG-TERM OBLIGATIONS

ARC Agreement

In October 2014, TOCCO, SHR, GSPL and TC (SHR, GSPL and TC collectively the “Guarantors”) entered into an amended and restated
credit  agreement  (as  amended  to  the  date  hereof,  the  “ARC Agreement”),  which  originally  provided  (i)  a  revolving  credit  facility  (the
“Revolving Facility”) with revolving commitments of $40.0 million and (ii) term loan borrowings consisting of (A) a  $70.0 million single
advance term loan incurred to partially finance the acquisition of TC (which we refer to as the “Acquisition loan”) and (B) a $25.0 multiple
advance  term  loan  facility  for  which  borrowing  availability  ended  on  December  31,  2015  (collectively,  the  “Term  Loan  Facility”  and,
together with the Revolving Facility, the “Credit Facilities”).

Only  July  31,  2018,  TOCCO  and  the  Guarantors  entered  into  a  Fourth Amendment  to  the ARC Agreement  (the  “Fourth Amendment”)
pursuant  to  which  the  revolving  commitments  under  the  Revolving  Facility  were  increased  to $75.0  million.  Pursuant  to  the  Fourth
Amendment,  total  borrowings  under  the  Term  Loan  Facility  were  increased  to $87.5 million  under  a  single  combined  term  loan,  which
comprised new term loan borrowings together with approximately $60.4 million of previously

F-21

Table of Contents

outstanding  term  loans  under  the  Term  Loan  Facility.  The  $60.4 million  of  previously  outstanding  term  loans  included  the  remaining
outstanding balances on the Acquisition loan and the multiple advance term loan facility described above. Proceeds of the new borrowings
under the Term Loan Facility were used to repay a portion of the outstanding borrowings under the Revolving Facility and pay fees and
expenses of the transaction. As of December 31, 2018, we had $18 million in borrowings outstanding under the Revolving Facility and
$84.5  million  in  borrowings  outstanding  under  the  Term  Loan  Facility.  In  addition,  we  had  approximately  $18  million  of  available
borrowings  under  our  Revolving  Facility  at  December  31,  2018.  TOCCO’s  ability  to  make  additional  borrowings  under  the  Revolving
Credit Facility at December 31, 2018 was limited by, and in the future may be limited by our obligation to maintain compliance with the
covenants  contained  in  the  ARC  Agreement  (including  maintenance  of  a  maximum  Consolidated  Leverage  Ratio  and  minimum
Consolidated Fixed Charge Coverage Ratio (each as defined in the ARC Agreement)).

The  maturity  date  for  the ARC Agreement  is  July  31,  2023.  Subject  to  the  lenders  acceptance  of  any  increased  commitment  and  other
conditions, we have the option, at any time, to request an increase to the commitment under the Revolving Facility and/or the Term Loan
Facility by an additional amount of up to $50.0 million in the aggregate.

Borrowings  under  each  of  the  Credit  Facilities  bear  interest  on  the  outstanding  principal  amount  at  a  rate  equal  to  LIBOR  plus  an
applicable margin of 1.25% to 2.50% or, at our option, the Base Rate plus an applicable margin of 0.25% to 1.50% , in each case, with the
applicable  margin  being  determined  based  on  the  Consolidated  Leverage  Ratio  of  TOCCO.  A  commitment  fee  between  0.20%  and
0.375%  is  also  payable  quarterly  on  the  unused  portion  of  the  Revolving  Facility.  For  2018,  the  effective  interest  rate  for  the  Credit
Facilities  was 4.19%.  Borrowings  under  the  Term  Loan  Facility  are  subject  to  quarterly  amortization  payments  based  on  a  commercial
style amortization method over a twenty year period; provided, that the final principal installment will be paid on the maturity date and
will be in an amount equal to the outstanding borrowings under the Term Loan Facility on such date.

Pursuant to the terms of the ARC Agreement, TOCCO must maintain a maximum Consolidated Leverage Ratio of  4.75 to 1.00 for the four
fiscal quarters ended December 31, 2018, 4.25 to 1.00 for the four fiscal quarters ended March 31, 2019, 4.00  to 1.00 for the four fiscal
quarters  ended  June  30,  2019  and 3.75  to 1.00 for the four fiscal quarters ended September 30, 2019. For the four fiscal quarters ended
December 31, 2019 and each fiscal quarter thereafter, TOCCO must maintain a Consolidated Leverage Ratio of 3.50  to 1.00 (subject to
temporary increase following certain acquisitions). Additionally, TOCCO must maintain a minimum Consolidated Fixed Charge Coverage
Ratio as of the end of any fiscal quarter of 1.15 to 1.00.

The ARC Agreement  contains,  among  other  things,  other  customary  covenants,  including  restrictions  on  the  incurrence  of  additional
indebtedness,  the  granting  of  additional  liens,  the  making  of  investments,  the  disposition  of  assets  and  other  fundamental  changes,
transactions with affiliates and the declaration of dividends and other restricted payments. The ARC Agreement further includes customary
representations and warranties and events of default, and upon occurrence of such events of default the outstanding obligations under the
ARC Agreement may be accelerated and become immediately due and payable and the commitment of the lenders to make loans under the
ARC Agreement may be terminated. We were in compliance with all covenants at December 31, 2018.

Principal payments of long-term debt for the next five years and thereafter ending December 31 are as follows:

On October 24, 2010, we executed a limited guarantee in favor of the Saudi Industrial Development Fund ("SIDF") whereby we agreed to
guaranty up to 41% of the SIDF loan to AMAK in the principal amount of  330.0 million Saudi Riyals (US$88.0 million) (the "Loan"). The
term of the loan is currently through June 2022. As a condition of the Loan, SIDF required all shareholders of AMAK to execute personal
or corporate guarantees; as a result, the Company's guarantee is for approximately 135.3 million Saudi Riyals (US$36.1 million). The loan
was  necessary  to  continue  construction  of  the AMAK  facilities  and  provide  working  capital  needs.  Our  current  assessment  is  that  the
probability of contingent performance is remote based on our analysis of the contingent portion of the guarantee which included but was
not limited to the following: (1) the SIDF has historically not called guarantees, (2) the value of the assets exceeds the amount of the loan
(3)  the  other  shareholders  have  indicated  that  they  would  prioritize  their  personal  guarantees  ahead  of  the  corporate  guarantee,  and  (4)
according  to  Saudi Arabian  legal  counsel,  assets  outside  of  Saudi Arabia  are  protected  from  the  Saudi  Court  System.  We  received  no
consideration  in  connection  with  extending  the  guarantee  and  did  so  to  maintain  and  enhance  the  value  of  our  investment.  Our  non-
contingent and immediate obligation to stand ready to make payments if the events of default under the guarantee occur was not material
to the financial statements. The total amount outstanding to the SIDF at December 31, 2018, and 2017 was 305.0 million and 305.0 million
Saudi Riyals (US$81.3 million and $81.3 million), respectively.

Operating Lease Commitments

We have operating leases for the rental of approximately  346 railcars for shipping purposes with expiration dates through 2026. Invoices
are received and paid on a monthly basis. The total amount of the commitment is approximately $17.3 million over the next 9 years.

We also have an operating lease for our office space in Sugar Land, Texas. The expiration date for this lease is September  2023. The total
amount of the commitment is approximately $587,000. In addition, we are required to make periodic payments for property taxes, utilities
and common area operating expenses.

In addition, we have operating leases for other equipment such as forklifts and copiers with varying expiration dates through  2023. These
commitments are approximately $207,000.

Future minimum property and equipment lease payments under the non-cancelable operating leases at  December 31, 2018, are as follows:

Rental expense for these operating leases for the years ended  December 31, 2018, 2017, and 2016 was $4.4 million, $4.4 million  and $4.2

Litigation

From time to time, we may become party to litigation or other legal proceedings that we consider to be a part of the ordinary course of our
business. We are not currently involved in any legal proceedings that we believe could reasonably be expected to have a material adverse
effect on our business, prospects, financial condition or results of operations. We may become involved in material legal proceedings in the
future.

On March 21, 2011, Mr. El Khalidi filed suit against the Company in Texas alleging breach of contract and other claims. The 88th Judicial
District Court of Hardin County, Texas dismissed all claims and counterclaims for want of prosecution in this matter on July 24, 2013. The
Ninth  Court  of Appeals  subsequently  affirmed  the  dismissal  for  want  of  prosecution  and  the  Supreme  Court  of  Texas  denied  Mr.  El
Khalidi's  petition  for  review.  On  May  1,  2014,  Mr.  El  Khalidi  refiled  his  lawsuit  against  the  Company  for  breach  of  contract  and
defamation in the 356th Judicial District Court of Hardin County, Texas. The case was transferred to the 88th Judicial District Court of
Hardin County, Texas. The Trial Court dismissed all of Mr. El Khalidi's claims and causes of action with prejudice and the Ninth Court of
Appeals affirmed. Mr. El Khalidi filed a petition for review with the Supreme Court of Texas, which was denied April 6, 2018. Mr. El
Khalidi filed a motion for rehearing of his petition for review with the Supreme Court of Texas on April 23, 2018. On May 25, 2018, the
Supreme Court of Texas denied the motion for rehearing and the matter is considered closed.

Supplier Agreements

From  time  to  time,  we  may  incur  shortfall  fees  due  to  feedstock  purchases  being  below  the  minimum  amounts  as  prescribed  by  our
agreements with our suppliers. The shortfall fee expenses were not significant for the years ended December 31, 2018, 2017, and 2016.

Environmental Remediation

Amounts  charged  to  expense  for  various  activities  related  to  environmental  monitoring,  compliance,  and  improvements  were
approximately $745,000 in 2018, $593,000 in 2017 and $622,000 in 2016.

NOTE 15 - SHARE-BASED COMPENSATION

The Stock Option Plan for Key Employees, as well as, the Non-Employee Director Stock Option Plan (hereinafter collectively referred to
as the “Stock Option Plans”), were approved by the Company’s shareholders in July 2008. The Stock Option Plans allot for the issuance of
up to 1,000,000 shares.

The Trecora Resources Stock and Incentive Plan (the “Plan”) was approved by the Company’s shareholders in June 2012. The Plan allots
for the issuance of up to 1,500,000 shares in the form of stock options or restricted stock unit awards.

F-24

 
 
Table of Contents

Share-based  compensation  of  approximately  $1.8  million, $2.7  million,  and $2.6  million  was  recognized  in  2018,  2017,  and  2016,
respectively. The Company reclassified approximately $318,000 for 2018 from share-based compensation expense in connection with the
restructuring described in Note 21.

Stock Options and Warrant Awards

Stock options and warrants granted under the provisions of the Stock Option Plans permit the purchase of our common stock at exercise
prices equal to the closing price of Company common stock on the date the options were granted. The options have terms of 10 years and
generally vest ratably over terms of 4 to 5 years. There were no stock options or warrant awards issued during 2018, 2017, or 2016.

The  aggregate  intrinsic  value  of  options  was  calculated  as  the  difference  between  the  exercise  price  of  the  underlying  awards  and  the
quoted price of our common stock. At December 31, 2018, options to purchase approximately 0.5 million shares of common stock were in-
the-money.

Since no options were granted, the weighted average grant-date fair value per share of options granted during the years 2018, 2017, and
2016 was $0. During 2018, 2017, and 2016 the aggregate intrinsic value of options and warrants exercised was approximately $2,630,000,
$164,000 and $237,000 respectively, determined as of the date of option exercise.

The Company received approximately $912,000, $25,000 and $11,000 in cash from the exercise of options during 2018, 2017 and 2016,
respectively. Of the approximately 378,000 stock options and warrants exercised, the Company only issued approximately 268,000 shares
due to cashless transactions. The tax benefit realized from the exercise was insignificant.

As of December 31, 2018, there was no unrecognized compensation costs related to non-vested share-based compensation.

Post-retirement compensation of approximately $680,000 and $0 during the years ended December 31, 2018 and 2017, respectively, was
reversed related to options awarded to Mr. Hatem El Khalidi in July 2009. On May 9, 2010, the Board of

F-25

 
   
   
   
   
   
 
Table of Contents

Directors determined that Mr. El Khalidi forfeited these options and other retirement benefits when he made various demands against the
Company and other AMAK shareholders which would benefit him personally and were not in the best interests of the Company and its
shareholders.  The  Company  was  successful  in  litigating  its  right  to  withdraw  the  options  and  benefits  and  as  such,  these  options  and
benefits were reversed during the second quarter of 2018. 

Restricted Stock and Restricted Stock Unit Awards

Generally,  restricted  stock  and  restricted  stock  unit  awards  are  granted  annually  to  officers  and  directors  of  the  Company  under  the
provisions of the Plan. Restricted stock units are also granted ad hoc to attract or retain key personnel, and the terms and conditions under
which these restricted stock units vest vary by award. The fair market value of restricted stock units granted is equal to the Company’s
closing  stock  price  on  the  date  of  grant.  Restricted  stock  units  granted  generally  vest  ratably  over  periods  ranging  from 2.5  to 5  years.
Certain awards also include vesting provisions based on performance metrics. Upon vesting, the restricted stock units are settled by issuing
one share of Company common stock per unit.

A summary of the status of the Company's restricted stock units activity is as follows:

Permanent  differences  are  primarily  due  to  the  Federal  manufacturer's  deduction,  research  and  development  credit,  and  stock  based
compensation.

The  Company  has  recognized  the  provisional  tax  impacts  related  to  the  acceleration  of  depreciation  and  included  these  amounts  in  its
consolidated financial statements for the year ended December 31, 2018. After the analysis, the Company did not identify items for which
the income tax effects of the TCJA have not been completed and a reasonable estimate could not be determined as of December 31, 2018.

The  changes  to  existing  U.S.  tax  laws  as  a  result  of  the  TCJA,  which  will  have  the  most  significant  impact  on  the  Company's  federal
income taxes are as follows:

Reduction of the U.S. Corporate Income Tax Rate - The Company uses the asset and liability method of accounting for income
taxes. Under this method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences
between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets
and  liabilities  are  measured  using  enacted  tax  rates  expected  to  apply  to  taxable  income  in  the  years  in  which  those  temporary
differences  are  expected  to  reverse. As  a  result  of  the  reduction  in  the  U.S.  corporate  income  tax  rate  from 35%  to 21%  under  the
TCJA, the Company revalued its ending net deferred tax liabilities at December 31, 2017.

Acceleration  of  Depreciation  -  The  Company  recognized  a  provisional  reduction  to  net  deferred  tax  assets  attributable  to  the
accelerated  depreciation  for  certain  assets  placed  into  service  after  September  27,  2017.  The  provisional  estimate  was  finalized
including consideration of TCJA on long term construction projects.

In connection with the proceeds received from AMAK in connection with its share repurchase program, the Company accrued a deferred
tax asset (foreign tax credit) and the corresponding liability for the anticipated Saudi Arabian tax.

We  provided  a  valuation  allowance  in 2018  and 2017  against  certain  deferred  tax  assets  because  of  uncertainties  regarding  their
realization. There was no change in the valuation allowance for 2018 or 2017.

We file an income tax return in the U.S. federal jurisdiction and a margin tax return in Texas. We received notification from the Internal
Revenue Service ("IRS") in November 2016 on the selection of the December 31, 2014 tax return for audit. The IRS expanded its audit to
include the Research and Development ("R&D") Credits for the year ended December 31, 2015. The IRS closed its audit without change
in March 2018. We also received notification that Texas will audit our R&D credit calculations for 2014 and 2015. The state of Texas has
suspended the audit of the Company's R&D credit. Texas is comprehensively reviewing their audit procedures for consistency. We do not
expect any changes related to the Texas audits. Our federal and Texas tax returns remain open for examination for the years 2015 through
2018.

We recognized no adjustment for uncertain tax positions.  As of  December 31, 2018, and 2017, no interest or penalties related to uncertain
tax positions had been accrued.

NOTE 17 – SEGMENT INFORMATION

We operate in two business segments; specialty petrochemical and specialty waxes. We operate through business segments according to
the  nature  and  economic  characteristics  of  our  products  as  well  as  the  manner  in  which  the  information  is  used  internally  by  our  key
decision maker, who is our Chief Executive Officer. The accounting policies of the reporting segments are the same as those described in
Note 2.

Our specialty petrochemical segment includes SHR and GSPL. Our specialty wax segment includes TC. We also separately identify our
corporate overhead which includes financing and administrative activities such as legal, accounting, consulting, investor relations, officer
and director compensation, corporate insurance, and other administrative costs.

upon  the  exercise  of  options  and  warrants. At  December  31,  2018,  the  Company  had  397  unvested  restricted  stock  units  and 264  stock
options that were not included in the computation of diluted earnings per share because the effect of conversion would be anti-dilutive due
to the Company incurring net loss for operations for the year ended December 31, 2018.

In 2018, we completed an exchange of shares with certain shareholders whereby such shareholders traded 65,000 common shares of TREC
in exchange for 24,489 shares of our AMAK stock.  The 65,000 shares were accounted for as treasury stock.

(1) Basic and diluted earnings per share are computed independently for each of the quarters presented based on the weighted

average number of common shares outstanding during that period. Therefore, the sum of quarterly basic and diluted per share
information may not equal annual basic and diluted earnings per share.

(2) As discussed in Note 16 the TCJA changed the federal corporate income tax rates from 35% to 21% resulting in a benefit from

deferred taxes of approximately $10.3 million.

NOTE 20 – RELATED PARTY TRANSACTIONS

Consulting fees of approximately $28,000, $27,000 and $33,000 were incurred during 2018, 2017, and 2016, respectively from IHS Global
FZ LLC of which Company Director Gary K. Adams held the position of Chief Advisor – Chemicals until April 1, 2017. At  December 31,
2018, and 2017, we had no outstanding liability payable to IHS Global FZ LLC.

Consulting fees of approximately $94,000, $74,000 and $73,000 were incurred during 2018, 2017, and 2016, respectively, from Chairman
of the Board, Nicholas Carter. Due to his history and experience with the Company and to provide continuity after his retirement, a three
year consulting agreement was entered into with Mr. Carter in July 2015. At  December 31, 2018, and 2017, we had no outstanding liability
payable to Mr. Carter.

NOTE 21 – RESTRUCTURING AND SEVERENCE EXPENSES

During 2018, the Company incurred restructuring and severance expenses of approximately $2.3 million related to changes in executive
management  and  the  completion  of  projects  in  our  specialty  petrochemical  segment.  These  expenses  relate  to  severance,  stock
compensation  for  continued  vesting  of  time-vested  shares  issued  under  the  Company's  long-term  incentive  plans,  and  certain  employee
benefits including medical insurance and vacation. As of December 31, 2018, approximately  $1.2 million remains unpaid and is included
in accrued liabilities.

NOTE 22- POST-RETIREMENT OBLIGATIONS

In January 2008, an amended retirement agreement was entered into with Mr. Hatem El Khalidi; however, on May 9, 2010, the Board of
Directors  terminated  the  agreement  due  to  actions  of  Mr.  El  Khalidi.  See  Note  14. All  amounts  which  had  not  met  termination  dates
remained recorded until a resolution was achieved. The matter was resolved on May 25, 2018 and as of June 30, 2018, post-retirement
obligations of approximately $1.0 million for Mr. El Khalidi have been reversed. As of December 31, 2017, approximately  $1.0 million
remained outstanding and was included in post-retirement benefits.

In  July  2015  and  June  2018,  we  entered  into  retirement  agreements  with  our  former  CEO,  Nicholas  Carter,  and  our  former  VP  of
Accounting & Compliance, Connie Cook. Mr. Carter's agreement provides continued welfare benefits for him and his wife for life at the
same  cost  sharing  basis  as  regular  employees.  Ms.  Cook's  agreement  provides  continued  welfare  benefits  for  her  and  her  husband  until
eligible for Medicare. Approximately $377,000 and $249,000 was outstanding at December 31, 2018, and 2017, respectively, and included
in post-retirement benefits. For the period ended December 31, 2018, and 2017, approximately $18,000 and $16,000, respectively had been
paid.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and
Shareholders of Al Masane Al Kobra Mining Company
Najran, Kingdom of Saudi Arabia

Opinion on the Financial Statements
We have audited the accompanying balance sheets of Al Masane Al Kobra Mining Company (the Company) as of December 31, 2018 and
2017,  and  the  related  statements  of  operations,  changes  in  shareholders’  equity,  and  cash  flows  for  each  of  the  years  in  the  three-year
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 years in the three-year period ended December 31, 2018, in conformity with accounting
principles generally accepted in the United States of America.

Basis for Opinion
These  financial  statements  are  the  responsibility  of  the  Company’s  management.  Our  responsibility  is  to  express  an  opinion  on  the
Company’s  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 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 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  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  financial  statements.  We  believe  that  our  audits
provide a reasonable basis for our opinion.

We have served as the Company’s auditor since 2013.

Note 1 – Organization and Business

Organization
Al Masane Al Kobra Mining Company is a Saudi Arabian closed joint stock company approved by the Minister of Commerce and Industry
Decree Number 247/Q dated 9/10/1428 (October 21, 2007) and registered in Jeddah under Commercial Registration No. 4030175345 on
7/1/1429  (January  16,  2008).  During  2015,  the  head  office  was  moved  from  Jeddah  to  Najran.  Accordingly,  Najran  Commercial
Registration  No.  5950017523  dated  03/11/1431H  (October  11,  2010)  was  modified  to  be  the  main  Commercial  Registration.  Unless  the
context  requires  otherwise,  references  to  “we”,  “us”,  “our”,  “AMAK”,  and  the  “Company”  are  intended  to  mean Al  Masane Al  Kobra
Mining Company. All amounts are expressed in Saudi Riyals (SR) unless otherwise noted.

During 2009 the authorized capital of the Company was  450,000,000 consisting of 45 million shares of 10 each of which 50% were issued
for  cash.  The  remaining 50%  were  issued  for  the  contribution  of  mining  rights  and  assets  from  Trecora  Resources  (Trecora)  subject  to
Trecora’s liability for a loan in the amount of 41,250,000 due to the Ministry of Finance and National Economy. The mining rights in Al
Masane mine were originally granted by Royal Decree Number M/17 effective 1/12/1413 (May 22, 1993) for a period of thirty years, with
a right of renewal for a further period of twenty years to Trecora. The mining rights granted Trecora the right of exploitation in Al Masane
mine located in Najran, Saudi Arabia, with an area of 44 square kilometers for a surface rental of 10,000 per square kilometer per year, i.e.
440,000  per  year.  As  per  the  Ministry  of  Petroleum  and  Mineral  Resources  resolution  dated  13/9/1429  (13/9/2008)  and  the  ministry
subsequent letter dated 2/1/1430 (30/12/2008), the aforementioned rights were transferred to us.

During  2011  the  Company  increased  its  authorized  share  capital  by  SR50,000,000 to SR500,000,000  and  issued 5,000,000  shares  of 10
each  at  a  price  of  SR28  each  resulting  in  a  share  premium  of  SR90,000,000.  The  entire 5,000,000  shares  were  issued  for  cash  to Arab
Mining Company (ARMICO) headquartered in Amman, Jordan.

During  2013  the  Company  increased  its  authorized  share  capital  by  SR50,000,000 to SR550,000,000  and  issued 5,000,000  shares  of 10
each at a price of SR30 each resulting in a share premium of SR100,000,000. The shares were issued for cash to existing shareholders.

During 2015 the Company increased its authorized share capital by SR190,000,000 to SR 740,000,000 and issued 19,000,000 shares of 10
each by transferring from share premium accounts.

During 2016 the Company increased its authorized share capital by SR40,000,000  to  SR 780,000,000  and  issued 4,000,000  shares  of 10
each at a price of SR20 each resulting in a share premium of SR35,092,840.

During 2018 the Company increased share premium by SR2,453,580 for shares that were previously issued.

During  2018  the  Company  increased  its  authorized  share  capital  by  SR40,000,000 to SR820,000,000  and  issued 4,000,000  shares  of 10
each by transferring from share premium accounts.

During the Company’s Extraordinary General Assembly Meeting in October of 2018, the shareholders approved to repurchase  2,500,000
shares  from  the  shareholders  at  a  price  of  SR30  each  and  to  register  these  shares  as  treasury  shares.  In  December  2018,  the  Board
unanimously approved this proposal and authorized the CEO to proceed with the repurchase. The Company began advancing shareholders
their portion of these proceeds in anticipation of completing and finalizing the treasury stock repurchase in 2019. As of December 31, 2018,
the Company had advanced SR52,562,028 to shareholders.

Except for Trecora and ARMICO, all other shareholders are Saudi nationals or companies wholly owned by Saudi nationals. Our ownership

Business and operations
Our principal activity is to produce zinc and copper concentrates and silver and gold doré as per the license Number 993/2 dated 16/7/1428
(July 31, 2007) issued by Saudi Arabian General Investment Authority (SAGIA). We commenced our commercial production on July 1,
2012. During 2015, we received a new mining lease for an area near our current mining area for the Guyan ancient mine.

On  16/11/1428  (November  26,  2007),  while  the  Company  was  in  the  registration  process,  the  Company  signed  a  contract  with  China
National  Geological  and  Mining  Corporation  (CGM)  for  underground  mine  rehabilitation,  pre-production  activity,  and  on-going  mine
development/production and with Nesma & Partners Contracting Company Limited (Nesma) for engineering, procurement, construction,
commissioning  and  hand  over  of  the  concentrator  surface  works  and  the  related  infrastructure  facilities.  The  handover  of  these  facilities
was finalized on November 28, 2011. In late 2014, we renegotiated a more favorable plant operations and maintenance contract with CGM.
CGM ran our mining operations until November 2015, at which time the Board of Directors cancelled the CGM and Nesma contract and
temporarily suspended operations of the Company. See Note 8.

This planned, temporary shutdown of the facility was due to the continued depressed commodity price environment as well as needs for
renovation and maintenance. Our focus during the renovation focused on improving recoveries overall and upgrading the precious metals
circuit through the installation of SART (sulfidization, acidification, recycling, and thickening) modifications which are expected to lower
chemical  use,  thereby  reducing  operating  costs.  In  February  2016,  we  entered  into  a  new  operating  and  rehabilitation  contract  with  a
different vendor under more favorable terms.

We resumed operations in the first quarter of 2017 and generated enough ore for  two shipments in 2017. In 2018, we resumed our schedule
of 4 shipments a year.

Note 2 - Summary of Significant Accounting Policies

The  accompanying  financial  statements  have  been  prepared  using  U.S.  generally  accepted  accounting  principles.  The  following  is  a
summary of our significant accounting policies:

Cash and cash equivalents
We consider all highly-liquid investments purchased with an original maturity of three months or less to be cash equivalents.

Accounts receivable
We evaluate the collectability of our accounts receivable and the adequacy of the allowance for doubtful accounts based upon historical
experience and any specific customer financial difficulties of which the Company becomes aware. During the years ended December 31,
2018, 2017, and 2016, we sold our concentrates and doré pursuant to a sales contract with one customer. No amounts have been written off
for  the  years  ended  December  31,  2018,  2017,  and  2016.  In  addition,  we  determined  that  an  allowance  for  doubtful  accounts  was  not
necessary at December 31, 2018 and 2017.

Inventories
The components of inventories include mill stockpiles, precious metal doré, chemicals, and mining supplies. Inventories are stated at the
lower  of  weighted-average  cost  or  market.  Costs  of  mill  stockpiles  inventory  include  labor  and  benefits,  supplies,  energy,  depreciation,
depletion, amortization, and other necessary costs incurred with the extraction and processing of ore. Corporate general and administrative
costs are not included in inventory costs.

Because  it  is  generally  impracticable  to  determine  the  minerals  contained  in  mill  stockpiles  by  physical  count,  reasonable  estimation
methods are employed. The quantity of material delivered to the mill stockpiles is based on surveyed volumes of mined material and daily
production records. Expected mineral recovery rates from the mill stockpiles are determined by various metallurgical testing methods.

Property and equipment
Property and equipment is carried at cost less accumulated depreciation. Expenditures for replacements and improvements are capitalized.
Costs related to periodic maintenance are expensed as incurred. Depletion of the mining assets is determined using the unit-of-production
method based on total estimated proven and probable reserves. Depletion and amortization using the unit-of-production method is recorded
upon extraction of the ore, at which time it is allocated to inventory cost and then included as a component of cost of goods sold. Other
assets are depreciated on a straight-line basis over their estimated useful lives ranging from 3 to 20 years.

9

 
Table of Contents

Borrowing costs that are directly attributable to the acquisition, construction or production of assets are capitalized as part of the cost of
those assets. Assets under construction are capitalized in the construction in progress account. Upon completion, the cost of the related asset
is transferred to the appropriate category of property and equipment.

Development costs
Mineral  exploration  costs,  as  well  as  drilling  and  other  costs  incurred  for  the  purpose  of  converting  mineral  resources  to  proven  and
probable reserves or identifying new mineral resources are charged to expense as incurred. Development costs are capitalized beginning
after  proven  and  probable  reserves  have  been  established.  Development  costs  include  costs  incurred  in  mine  pre-production  activities
undertaken  to  gain  access  to  proven  and  probable  reserves,  including  shafts,  drifts,  ramps,  permanent  excavations,  infrastructure  and
removal of overburden. These costs are deferred net of the proceeds from the sale of any production during the development period and
then  amortized  using  an  estimated  unit-of-production  method.  If  a  mine  is  no  longer  considered  economical,  the  accumulated  costs  are
charged to the statement of operations in the year in which the determination is made.

Asset impairment
We review and evaluate our long-lived assets for impairment when events or changes in circumstances indicate that the carrying amounts
may not be recoverable. Long-lived assets are evaluated for impairment under the two-step model. When events or circumstance suggest
impairment  of  long-lived  assets,  estimated  undiscounted  future  net  cash  flows  are  calculated  using  future  estimated  commodity  prices,
proven and probable reserves, and estimated net proceeds from the disposition of assets on retirement, less operating, sustaining capital, and
reclamation costs. If it is determined that an impairment exists, an impairment loss is measured as the amount by which the asset carrying
value exceeds its fair value. Fair value is generally determined using valuation techniques such as estimated future cash flows. Because the
cash flows used to assess recoverability of our long-lived assets and measure fair value of our mining operations require us to make several
estimates  and  assumptions  that  are  subject  to  risk  and  uncertainty,  changes  in  these  estimates  and  assumptions  could  result  in  the
impairment of our long-lived asset values.

Based on our evaluation, we recorded no impairment losses during the years ended December 31, 2018, 2017 and 2016.

End-of-service indemnities
Employee  end-of-service  benefits  are  accrued  for  the  benefit  of  employees  under  the  terms  and  conditions  of  Saudi  Labor  Law  and
Regulations and their employment contracts. End-of-service indemnities are provided for and accrued in the financial statements based on
the respective employees' salaries and length of service.

Pre-export Advances
At  times  we  receive  advances  on  a  pre-export  basis  against  a  portion  of  our  inventory  on  hand  prior  to  shipment.  These  advances  bear
interest  at 2.5%  and  are  repaid  from  the  proceeds  from  final  concentrate  sales.  We  did  not  have  an  outstanding  advance  liability  at
December 31, 2018 and 2017.

Foreign currency
Our functional currency is the Saudi Riyal (SR). In June 1986, the Saudi Riyal was officially pegged to the U.S. Dollar at a fixed exchange
rate of 1 U.S. Dollar to 3.75 riyals. Foreign currency transactions are translated into Saudi Riyals at the rates of exchange prevailing at the
time  of  the  transactions.  Monetary  assets  and  liabilities  denominated  in  foreign  currencies  at  the  balance  sheet  date  are  translated  at  the
exchange rates prevailing at that date. Any gains and losses from settlement and translation of foreign currency transactions are included in
the statement of operations. There were no material foreign-currency exchange gains or losses or translation adjustments during the years
ended December 31, 2018, 2017, and 2016.

Leasing arrangements
We  periodically  lease  operating  equipment,  facilities,  and  office  buildings.  Rentals  payable  under  operating  leases  are  charged  to  the
statements  of  operations  on  a  straight-line  basis  over  the  term  of  the  relevant  lease.  For  any  capital  leases,  the  present  value  of  future
minimum lease payments at the inception of the lease is reflected as an asset and a liability in the balance sheet. Amounts due within one
year are classified as short-term liabilities and the remaining balance as long-term liabilities. Finance charges are charged to the statement
of operations.

Operating lease expense amounted to approximately SR1,619,000, SR1,454,000 and SR442,000 for the years ended December 31, 2018,
2017 and 2016, respectively.

Environmental costs
Environmental  costs  are  expensed  or  capitalized,  depending  upon  their  future  economic  benefits.  Accruals  for  such  expenditures  are
recorded when it is probable that obligations have been incurred and the costs can reasonably be estimated. Ongoing compliance costs are
expensed as incurred.

10

Table of Contents

Asset retirement obligations and costs
We record the fair value of our estimated asset retirement obligations (AROs) associated with tangible long-lived assets in the period in
which  the  obligation  is  incurred. AROs  associated  with  long-lived  assets  are  those  for  which  there  is  a  legal  obligation  to  settle  under
various laws, statues, or regulations. These obligations, which are initially estimated based on discounted cash flow estimates, are accreted
to full value over time through charges to cost of revenues. In addition, asset retirement costs (ARCs) are capitalized as part of the related
asset’s carrying value and are depreciated (primarily on a unit-of-production basis) over the asset’s respective useful life. Our AROs consist
primarily  of  costs  associated  with  mine  reclamation  and  closure  activities  and  are  included  in  deferred  mine  closure  costs  on  the
accompanying  balance  sheets. At  least  annually,  we  review  our ARO  estimates  for  changes  in  the  projected  timing  and  changes  in  cost
estimates and additional AROs incurred during the period.

Zakat and income tax
We  are  subject  to  the  Regulations  of  the  General Authority  of  Zakat  and  Tax  (GAZT)  in  the  Kingdom  of  Saudi Arabia.  Under  these
regulations, Zakat is payable at 2.5% on the basis of the portion of our Zakat base attributable to our Saudi stockholders, and income tax is
payable at 20% on the portion of our taxable income attributable to our non-Saudi stockholders. Zakat and income tax are provided on an
accrual basis. Any difference in the estimate is recorded when the final assessment is approved, at which time the provision is cleared.

We  account  for  deferred  income  taxes  on  non-Saudi  owners  utilizing  an  asset  and  liability  method,  whereby  deferred  tax  assets  and
liabilities  are  recognized  based  on  the  tax  effects  of  temporary  differences  between  the  financial  statements  and  the  income  tax  basis  of
assets and liabilities, as measured by the effective tax rate. When appropriate, we evaluate the need for a valuation allowance based on a
more likely than not threshold to reduce deferred tax assets to estimated recoverable amounts.

We  account  for  uncertain  income  tax  positions  using  a  threshold  and  measurement  attribute  for  the  financial  statement  recognition  and
measurement of a tax position taken or expected to be taken in a tax return. We report tax-related interest and penalties as a component of
Zakat and income tax expense. We recognized no material adjustment for unrecognized income tax liabilities. Zakat and income tax returns
for the years from 2010 to 2017 are currently under review with GAZT.

Reclassifications
Certain reclassifications have been made to the prior periods to conform with current year presentation.

Revenue recognition
We sell our products pursuant to sales contracts entered into with a customer who acts as an intermediary and resells our products to end
users. Revenue is recognized when title and risk of loss pass to the customer and when collectability is reasonably assured. The passing of
title and risk of loss to the customer is based on terms of the sales contract, generally upon shipment or delivery of product.

Sales are recorded based on a provisional sales price or a final sales price calculated in accordance with the terms specified in the relevant
sales  contract.  Under  the  long-established  structure  of  sales  agreements  prevalent  in  the  industry,  the  copper  and  zinc  contained  in
concentrate is generally provisionally priced at the time of shipment. The provisional price received at the time of shipment is later adjusted
to a final price based on quoted monthly average spot prices on the London Metal Exchange (LME) for a specified future month. We record
revenues  at  the  time  of  shipment  (when  title  and  risk  of  loss  pass)  based  on  then-current  LME  prices,  and  we  account  for  any  changes
between the sales price recorded at the time of shipment and subsequent changes in the LME prices through the date of final pricing as
gains or losses from a derivative embedded in the sales contract (a futures contract initiated at the date of shipment and settled upon the
determination of the final price) which is bifurcated and separately accounted for at fair value. See Note 16.

Revenues  from  concentrate  sales  are  recorded  net  of  treatment  and  refining  charges.  These  allowances  are  a  negotiated  term  of  each
contract. Treatment and refining charges represent payments or price adjustments to smelters and refiners and are either fixed, or in certain
cases, vary with the price of metals (referred to as price participation).

Management estimates
The  preparation  of  financial  statements  in  conformity  with  accounting  principles  generally  accepted  in  the  United  States  of  America
requires  management  to  make  estimates  and  assumptions  that  affect  the  reported  amounts  of  assets  and  liabilities  and  disclosure  of
contingent  assets  and  liabilities  at  the  date  of  the  financial  statements  and  the  reported  amounts  of  revenues  and  expenses  during  the
reporting periods. The most significant areas requiring the use of management estimates include mineral reserve estimation; useful asset
lives  for  depreciation  and  amortization;  zakat  and  income  taxes;  environmental  obligations;  reclamation  and  closure  costs;  estimates  of
recoverable materials in mill stockpiles; fair value of embedded derivatives; end-of-service indemnities; and

asset impairment, including estimates used to derive future cash flows associated with those assets. Actual results could differ from these
estimates.

Recent accounting pronouncements
In May 2014 the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-09, Revenue from
Contracts  with  Customers  ("ASU  2014-09").  ASU  2014-09  supersedes  the  revenue  recognition  requirements  of  FASB  Accounting
Standards  Codification  ("ASC")  Topic  605,  Revenue  Recognition  and  most  industry-specific  guidance  throughout  the  Accounting
Standards Codification, resulting in the creation of FASB ASC Topic 606, Revenue from Contracts with Customers. ASU 2014-09 requires
entities to recognize revenue in a way that depicts the transfer of promised goods or services to customers in an amount that reflects the
consideration  to  which  the  entity  expects  to  be  entitled  to  in  exchange  for  those  goods  or  services.  For  nonpublic  companies  this ASU
provides alternative methods of retrospective adoption and is effective for fiscal years and interim periods beginning after December 15,
2018.  Early  adoption  is  permitted.  The  Company  is  evaluating  the  impact  of  these  amendments,  although  it  does  not  expect  the
amendments to have a significant impact to the Company’s financial position or results of operation.

In February 2016 the FASB issued ASU No. 2016-02, Leases (Topic 842), to increase transparency and comparability among organizations
by recognizing all lease transactions (with terms in excess of 12 months) on the balance sheet as a lease liability and a right-of-use asset (as
defined). The ASU is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, with
earlier  application  permitted.  Upon  adoption,  the  lessee  will  apply  the  new  standard  retrospectively  to  all  periods  presented  or
retrospectively  using  a  cumulative  effect  adjustment  in  the  year  of  adoption.  The  Company  has  several  lease  agreements  for  which  the
amendments will require the Company to recognize a lease liability to make lease payments and a right-of-use asset which will represent its
right to use the underlying asset for the lease term. As permitted by the amendments, the Company is anticipating electing an accounting
policy to not recognize lease assets and lease liabilities for leases with a term of twelve months or less. The Company is currently reviewing
the  amendments  to  ensure  it  is  fully  compliant  by  the  adoption  date  and  does  not  expect  to  early  adopt.  In  addition,  the  Company  will
change its current accounting policies to comply with the amendments with such changes as mentioned above.

Subsequent events
We have evaluated events and transactions subsequent to the date of the financial statements for matters requiring recognition or disclosure
in the financial statements. The accompanying financial statements consider events through March 6, 2019, the date on which the financial
statements were available to be issued.

Note 3 – Liquidity and Capital Resources

As  shown  in  the  financial  statements,  we  have  incurred three  consecutive  years  of  net  losses  however,  the  Company  resumed  full
operations and had operating income and cash provided from operations during the year ended December 31, 2018. In addition, we expect
to update our mineral resources and life of mine in 2019 with the expectation that the life of mine will be extended another two years. We
believe that our continued operations and the adjusted repayment terms of our outstanding debt will provide us the necessary liquidity and
capital resources.

Note 4 – Inventories

Inventories consisted of the following at:

Ore concentrates
Stockpile ore
Precious metal dore
Explosives
Chemicals and other

As discussed in Note 2, we can receive advances on a pre-export basis on our mill stockpiles.

On March 31, 2016, the Company entered into finalization and discharge memorandums of understanding (MOU’s) with their former mine
operator CGM and subcontractor Nesma where certain contracts were cancelled. These contracts included the EPC Surface Works Contract
and  Subcontract  (CGM/NESMA)  dated  November  26,  2007,  the  Underground  Mining  Contract  (CGM)  dated  June  29,  2010,  the  1st
Surface Works O&M Contract (CGM) dated July 3, 2011, and the 2nd Surface Works O&M Contract (CGM) dated November 3, 2014
(collectively, the Contracts).

The MOU’s were binding agreements between the Company, CGM and Nesma. All of CGM’s spare parts on site related to the Contracts
reverted to and became the property of the Company. CGM received payment of approximately SR4,500,000 and forfeited their rights to
the  spare  parts  that  had  an  economic  value  of  approximately  SR34,477,500.  The  spare  parts  were  recorded  at  SR4,500,000  and  were
included in property and equipment, net on the balance sheets. Under the MoU’s, CGM and Nesma did not receive any further payments
from the Company as full settlement against the deterioration of property, plant and equipment which exceeded normal wear and tear and
any other breach of contracts. In recognition of certain financial losses incurred by the Company, CGM and NESMA forfeited the recovery
of all remaining amounts due under the Contracts. The total amounts of liabilities recorded on the Company’s books as of March 31, 2016
were approximately SR65,345,000 which were written off to other income on the statement of operations for the year ended December 31,
2016. There were no outstanding or unresolved claims and all parties have fulfilled their obligations in connection with the Contracts.

Note 9 – Zakat and Income Tax

We have submitted our Zakat and income tax return for the year ended December 31, 2017 and have obtained our 2017 Zakat certificate.
We are in the process of preparing and submitting our Zakat and income tax return for the year 2018.

The Zakat base for the Saudi shareholders was positive in 2018, 2017 and 2016 and the corresponding Zakat expense and liability has been
recorded. There was a taxable profit attributable to our non–Saudi (foreign) shareholders in 2018 and the current income tax expense and
liability  has  also  been  recorded.  There  was  no  taxable  profit  attributable  to  our  non-Saudi  (foreign)  shareholders  for  2017  and  2016,
therefore, no current income tax liability is due in those years.

The components of Zakat and income tax benefit (expense) are as follows:

Deferred income tax benefit
Change in valuation allowance
Current Zakat and income tax expense

At  December  31,  2018  and  2017,  we  had  tax  loss  carryforwards  totaling  approximately  SR210,970,000  and  SR214,418,000.  Tax  losses
may  be  carried  forward  indefinitely  subject  to  certain  annual  limitations  for  non-Saudi  shareholders.  We  have  provided  a  valuation
allowance in 2018 and 2017 against a portion of our gross deferred tax assets because of uncertainties regarding their realization.

Note 10 - Long-term Debt

During 2010, the Company entered into a loan agreement with the Saudi Industrial Development Fund (SIDF) for SR 330,000,000 to finish
the  development  of  the  mine  and  provide  working  capital.  The  loan  originally  matured  in  2019,  however,  the  agreement  was  amended
during 2015 to adjust the maturity date to 2022 as well as the repayment schedule. We did not make certain scheduled loan repayments due
in 2017 and 2018 and engaged with SIDF to renegotiate the terms of the debt. In July 2018, we amended our agreement with SIDF to adjust
the repayment schedule and extend the maturity date to 2024. Under the terms of the agreement with SIDF, we are required to maintain
certain financial covenants, among other requirements. The loan agreement is collateralized by all the assets of Company and is guaranteed
by the shareholders.

Long-term debts are summarized as follows at:

SIDF loan agreement

Deferred finance costs are comprised of SIDF loan origination charges which are capitalized and amortized over the period of the related
loan which approximates the interest method. Loan fees of SR8,741,288 and SR10,917,190 net of accumulated amortization are included
net with long-term debt at December 31, 2018 and 2017. Amortization of loan fees amounted to approximately SR1,639,000, SR1,611,000,
and SR2,148,000 for the years ended December 31, 2018, 2017, and 2016, respectively.

Note 15 - Fair Value Measurement

Fair  value  accounting  guidance  includes  a  hierarchy  that  prioritizes  the  inputs  to  valuation  techniques  used  to  measure  fair  value.  The
hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 inputs) and the
lowest priority to unobservable inputs (Level 3 inputs).

Level 1

Level 2

Unadjusted  quoted  prices  in  active  markets  that  are  accessible  at  the  measurement  date  for  identical,  unrestricted
assets or liabilities;

Quoted  prices  in  markets  that  are  not  active,  quoted  prices  for  similar  assets  or  liabilities  in  active  markets,  inputs
other  than  quoted  prices  that  are  observable  for  the  asset  or  liability,  or  inputs  that  are  derived  principally  from  or
corroborated by observable market data by correlation or other means; and

Level 3

Prices  or  valuation  techniques  that  require  inputs  that  are  both  significant  to  the  fair  value  measurement  and
unobservable (supported by little or no market activity).

We did not have any significant transfers in or out of Levels 1, 2, or 3 in 2018 or 2017. The embedded derivatives in our provisional sales
contracts are considered Level 2 measurements.

Note 16 – Embedded Derivatives

As described in Note 2 under Revenue Recognition, our concentrate sales contracts provide for provisional pricing based on the LME price
at the time of shipment as specified in the contract. Sales contracts with a provisional sales price contain an embedded derivative (i.e., the
price  settlement  mechanism  that  is  settled  after  the  time  of  delivery)  that  is  required  to  be  bifurcated  from  the  host  contract.  The  host
contract is the sale of the metals contained in the concentrates at the then-current LME price as defined in the contract. Mark-to-market
price fluctuations recorded through the settlement date are reflected in revenues for sales contracts. Our embedded derivatives at December
31, 2018 and 2017, were not significant to the financial statements.

provisions of this Agreement.

4 . 2     Termination by the Company for Cause .  The Company may terminate Quarles’ employment at any
time  for  Cause. For  purposes  of  this Agreement,  “Cause”  shall  mean:  (i)  the  commission  by  Quarles  of,  or  pleading
guilty or nolo contendere to, a felony or a crime involving moral turpitude, (ii) Quarles’ willful and continued failure to

lawful directions or instructions of the Company’s Board, (iii) Quarles’ material breach of any fiduciary duty owed to
the  Company  or  any  of  its  affiliates,  (iv)  Quarles’  theft,  fraud,  embezzlement,  or  dishonesty  (including  intentional

Quarles’  intentional  material  violation  of  the  Company’s  code  of  conduct,  code  of  ethics  or  similar  written  policies,
including  but  not  limited  to  those  relating  to  sexual  harassment,  (vi)  Quarles’  willful  misconduct  unrelated  to  the

Company  or  any  of  its  affiliates  having,  or  likely  to  have,  a  material  negative  impact  on  the  Company  or  any  of  its
affiliates  (economically  or  to  its  reputation),  (vii)  any  intentional,  material  breach  or  violation  by  Quarles  of  any

automatically  (and  without  any  further  action  by  any  person  or  entity)  terminate  with  no  further  obligation  of  either
Party under this Agreement. For purposes of this Agreement, a “Disability” shall exist if Quarles is unable to perform
the  essential  functions  of  his  position  (after  accounting  for  reasonable  accommodation,  if  applicable  and  required  by
applicable law), due to physical or mental impairment that continues, or can reasonably be expected to continue, for a
period in excess of 120 consecutive days or 180 days, whether or not consecutive (or for any longer period as may be
required by applicable law), in any 12-month period. The determination of whether Quarles has incurred a Disability
shall be made in good faith by the Board.

4.5    Termination by Quarles other than for Good Reason . Quarles may terminate his employment at any
time and for any reason other than Good Reason by giving 60 days advance written notice to the Company prior to the

without Quarles’ prior written consent in Quarles’ authority, duties, responsibilities, or reporting line to the Company’s
Board, or (c) relocation of the work place of the Company to a location more than 100 miles from current location of
the Company’s headquarters or facilities. An event described in this Section 4.6 will not constitute Good Reason unless
Quarles  provides  written  notice  to  the  Company of  his  intention  to  resign  for  Good  Reason  and  specifying  in
reasonable detail the breach or action giving rise thereto within 90 days of its initial existence and the Company does
not  cure  such  breach  or  action  within  30  days  after  the  date  of  Quarles’  notice. In  no  instance  will  a  resignation  by
Quarles be deemed to be for Good Reason if it is made more than six months following the initial occurrence of any of
the events that otherwise would constitute Good Reason hereunder.

4 . 7    Deemed  Resignations.  Upon  the  effective  date  of  Quarles’  termination  of  employment  with  the
Company, Quarles shall be deemed to have resigned, to the extent applicable, as an officer of the Company and any
other affiliate of the Company, and as a member of the Board and the board of directors or similar governing body of
any of the Company’s affiliates and (if applicable) the board of directors of Al Masane Al Kobra Mining Company.

Each installment of severance payment will be treated as a separate payment for purposes of Internal Revenue Code

Quarles’  death  pursuant  to Section  4.4,  Quarles’  estate  or  his  beneficiaries,  as  the  case  may  be,  will  be  entitled  to

release against the Company or its affiliates, other than with respect to Quarles’ rights under Section 5.1,
and  such  release  shall  have  become  legally  effective  and  not  subject  to  revocation  within  60  days

ARTICLE VI

any  of  its  affiliates,  and  any  reference  to  “employment”  or  similar  terms  shall  include  an  officer,  director  and/or
consulting  relationship. Quarles  agrees  that  all  information,  inventions,  patents,  trade  secrets,  formulas,  processes,
designs,  ideas,  concepts,  improvements,  diagrams,  drawings,  flow  charts,  programs,  methods,  apparatus,  software,
hardware, ideas, improvements, product developments, discoveries, systems, techniques, devices, models, prototypes,
copyrightable works, mask works, trademarks, service marks, trade dress, business slogans, written materials and other
things of value conceived, reduced to practice, made or learned by Quarles, either alone or with others, while employed
with the Company (whether during business hours or otherwise and whether on the Company’s premises or otherwise)
that  relate  to  the  Company’s  business  using  the  Company’s  time,  data,  facilities  and/or  materials  (hereinafter
collectively  referred  to  as  the  “Work  Product”)  belong  to  and  shall  remain  the  sole  and  exclusive  property  of  the
Company forever. Quarles hereby assigns to the Company all of his right, title, and interest to all such Work Product.

Quarles agrees to promptly and fully disclose all Work Product in writing to the Company.  Quarles agrees to cooperate
and  do  all  lawful  things  requested  by  the  Company  to  protect  the  Company’s  ownership  rights  in  all  Work  Product.
Quarles warrants that no Work Product has been conceived, reduced to practice, made or learned by him prior to his
employment with the Company.

6 . 2    Confidential Information.  During  Quarles’  employment  with  the  Company,  the  Company  agrees  to,
and  shall  provide  to  Quarles,  confidential,  proprietary,  non-public  and/or  trade  secret  information  regarding  the
Company  that  Quarles  has  not  previously  had  access  to  or  knowledge  of  before  the  execution  of  this  Agreement
including,  without  limitation,  Work  Product,  technical  information,  corporate  opportunities,  product  specification,
compositions, manufacturing and distribution methods and processes, research, financial and sales data, business and
marketing  plans,  strategies,  financing,  plans,  business  policies  and  practices  of  the  Company,  know-how,  specialized
training, mailing lists, acquisition prospects, identity of suppliers, identity of customers or their requirements, any other
information related to customers or suppliers, the identity of key contacts within the customer’s organizations or within
the  organization  of  acquisition  prospects,  potential  client  lists,  employee  records,  pricing  information,  evaluations,
opinions, interpretations, production, marketing and merchandising techniques, prospective names and marks or other
forms of information considered by the Company to be confidential, proprietary, non-public or in the nature of trade
secrets (hereafter collectively referred to as “Confidential Information”) that the Company desires to protect.

6 . 3    No Unauthorized Use or Disclosure . Quarles agrees to preserve and protect the confidentiality of all
Confidential Information and Work Product of the Company. Quarles agrees that he will not, at any time during or after
his employment with the Company, make any unauthorized disclosure of, and he shall not remove from the Company
premises, Confidential Information or Work Product of the Company, or make any use thereof, except, in each case, in
the carrying out of his responsibilities hereunder. Quarles shall use all reasonable efforts to cause all persons to whom
any Confidential Information shall be disclosed by him to preserve and protect the confidentiality of such Confidential
Information. At  the  request  of  the  Company  at  any  time,  Quarles  agrees  to  deliver  to  the  Company  all  Confidential
Information that he may possess or control. Quarles agrees that all Confidential Information of the Company (whether
now  or  hereafter  existing)  conceived,  discovered  or  made  by  Quarles  during  the  period  of  his  employment  with  the
Company exclusively belongs to the Company (and not to Quarles), and upon request by the Company for specified
Confidential Information, Quarles will promptly disclose such Confidential Information to the Company and perform
all  actions  reasonably  requested  by  the  Company  to  establish  and  confirm  such  exclusive  ownership. As  a  result  of
Quarles’ employment with the Company, he may also from time to time have access to, or knowledge of, Confidential
Information or Work Product of third parties, such as customers, suppliers, partners, joint venturers, and the like, of the
Company. Quarles also agrees to preserve and protect the confidentiality of such third party Confidential Information
and  Work  Product.  Notwithstanding  anything  contained  in  this  Agreement  to  the  contrary,  Quarles  may  disclose
Confidential Information: (a) as such disclosure or use may be required or appropriate in connection with his work as an
employee of the Company; (b) when required to do so by a court of law, by any governmental agency having apparent
supervisory  authority  over  the  business  of  the  Company  or  by  any  administrative  or  legislative  body  (including  a
committee  thereof)  with  apparent  jurisdiction  to  order  him  to  divulge,  disclose  or  make  accessible  such  information;
provided, however, that in the event disclosure is so required, Quarles shall provide the Company with prompt notice of
such requirement prior to making any such disclosure, so that the Company may seek an appropriate protective order;
or (c) as to such Confidential Information that becomes generally known to the public or trade without his violation of
this Section 6.3. Upon termination of Quarles’ employment with the Company for any reason, Quarles shall promptly
deliver  such  Confidential  Information  and  Work  Product,  and  all  copies  thereof  (in  whatever  form,  tangible  or
intangible), to the Company. No Company policies or practices, including the sections herein addressing confidentiality
obligations,  are  intended  to  or  shall  limit,  prevent,  impede  or  interfere  in  any  way  with  Quarles’  right,  without  prior
notice to the Company, to provide information to the government, participate in investigations, testify in proceedings
regarding the Company’s past or future conduct or engage in any activities protected under whistle blower statutes.

6 . 4    Ownership by the Company . If, during Quarles’ employment with the Company, Quarles creates any
work  of  authorship  fixed  in  any  tangible  medium  of  expression  that  is  the  subject  matter  of  copyright  (such  as
videotapes, written presentations, or acquisitions, computer programs, electronic mail, voice mail, electronic databases,
drawings, maps, architectural renditions, models, manuals, brochures, or the like) relating to the Company’s business,
products, or services, whether such work is created solely by Quarles or jointly with others (whether during business
hours or otherwise and whether on the Company’s premises or otherwise), including any Work Product, the Company
shall be deemed the author of such work if the work is prepared by Quarles in the scope of his employment; or, if the
work  relating  to  the  Company’s  business,  products  or  services  is  not  prepared  by  Quarles  within  the  scope  of  his
employment  but  is  specially  ordered  by  the  Company  as  a  contribution  to  a  collective  work,  as  a  part  of  a  motion
picture  or  other  audiovisual  work,  as  a  translation,  as  a  supplementary  work,  as  a  compilation,  or  as  an  instructional
text, then the work shall be considered to be work made for hire, and the Company shall be the author of the work. If
the work relating to the Company’s business, products, or services is neither prepared by Quarles within the scope of
his employment nor a work specially ordered that is deemed to be a work made for hire during Quarles’ employment

with  the  Company,  then  Quarles  hereby  agrees  to  assign,  and  by  these  presents  does  assign,  to  the  Company  all  of
Quarles’ worldwide right, title, and interest in and to such work and all rights of copyright therein.

6 . 5    Assistance  by  Quarles.  During  the  period  of  Quarles’  employment  with  the  Company,  Quarles  shall
assist  the  Company,  at  any  time,  in  the  protection  of  the  Company’s  worldwide  right,  title  and  interest  in  and  to
Confidential  Information  and  Work  Product,  the  execution  of  all  formal  assignment  documents  requested  by  the
Company or its nominee, and the execution of all lawful oaths and applications for patents and registration of copyright
in  the  United  States  and  foreign  countries. After  Quarles’  employment  with  the  Company  terminates  and  subject  to
Section 8.1, at the request from time to time and expense of the Company, Quarles shall reasonably assist the Company
and its nominee, at reasonable times and for reasonable periods, in the protection of the Company’s worldwide right,
title  and  interest  in  and  to  Confidential  Information  and  Work  Product,  the  execution  of  all  formal  assignment
documents requested by the Company or its nominee, and the execution of all lawful oaths and applications for patents
and registration of copyright in the United States and foreign countries.

6 . 6    Remedies. Quarles acknowledges that money damages would not be a sufficient remedy for any breach
by  him  of  this Article  VI,  and  the  Company  shall  be  entitled  to  (a)  enforce  the  provisions  of  this  Article  VI  by
immediately terminating any payments then owing to, or the rights of, Quarles under Section 5.1(d) or otherwise upon
its determination of any such breach and (b) obtain specific performance and/or injunctive relief as remedies for such
breach or any threatened breach. Such remedies shall not be deemed the exclusive remedies for a breach of this Article
VI but shall be in addition to all remedies available at law or in equity, including the recovery of damages from Quarles
and his agents.

6.7    Immunity for Confidential Disclosure of Trade Secrets . Quarles shall not be held criminally or civilly
liable under any Federal or State trade secret law for the disclosure of a trade secret that is made in confidence either
directly  or  indirectly  to  a  Federal,  State  or  local  government  official,  or  to  an  attorney,  solely  for  the  purpose  of
reporting  or  investigating,  a  violation  of  law. Quarles  shall  also  not  be  held  criminally  or  civilly  liable  under  any
Federal or State trade secret law for the disclosure of a trade secret made in a complaint or other document filed in a
lawsuit  or  other  proceeding,  if  such  filing  is  made  under  seal. If  Quarles  files  a  lawsuit  alleging  retaliation  by  the
Company for reporting a suspected violation of the law, Quarles may disclose the trade secret to his attorney and use
the trade secret in the court proceeding, so long as any document containing the trade secret is filed under seal and does
not disclose the trade secret, except pursuant to court order. This Section 6.7 will govern to the extent it may conflict
with any other provision of this Agreement.

ARTICLE VII
NON-COMPETITION AND NON-SOLICITATION

7.1        For  purposes  of  this  Article VII,  the  term  “the  Company”  shall  include  the  Company  and  any  of  its
affiliates. The  Company  shall  provide  Quarles  access  to  Confidential  Information,  and  Quarles  acknowledges  and
agrees that the Company will be entrusting him, in his unique and special capacity, with developing the goodwill and
business  opportunities  of  the  Company,  and  in  consideration  of  the  Company  providing  Quarles  with  access  to
Confidential  Information  and  as  an  express  incentive  for  the  Company  to  enter  into  this  Agreement  and  employ
Quarles, Quarles has voluntarily agreed to the covenants set forth in this Article VII. Quarles agrees and acknowledges
that  the  limitations  and  restrictions  set  forth  herein,  including  geographical  and  temporal  restrictions  on  certain
competitive  activities,  are  reasonable  in  all  respects,  will  not  cause  Quarles  undue  hardship,  and  are  material  and
substantial parts of this Agreement intended and necessary to prevent unfair competition and to protect the Company’s
Confidential Information, goodwill and legitimate business interests.

7.2    During the Prohibited Period, Quarles shall not, without the prior written approval of the Board, directly

or indirectly, for Quarles or on behalf of or in conjunction with any other person or entity of any nature:

a.

b.

c.

d.

engage in or participate within the Market Area in competition with any member of the Company in any
aspect of the Business, which prohibition shall prevent Quarles from directly or indirectly: (i) owning,
managing, operating, or being an officer or director of, any business that competes with the Company in
the Market Area, or (ii) joining, becoming an employee or consultant of, or otherwise being affiliated
with,  any  person  or  entity  engaged  in,  or  planning  to  engage  in,  the  Business  in  the  Market Area  in
competition, or anticipated competition, with the Company in any capacity (with respect to this clause
(ii)) in which Quarles’ duties or responsibilities are the same as or similar to the duties or responsibilities
that he had on behalf of the Company;

appropriate  any  Business  Opportunity  of,  or  relating  to,  the  Company  located  in  the  Market
Area;

solicit,  canvass,  approach,  encourage,  entice  or  induce  any  customer  or  supplier  of  the  Company  to
cease or lessen such customer’s or supplier’s business with the Company; or

solicit, canvass, approach, encourage, entice or induce any employee or contractor of the Company to
terminate his, her or its employment or engagement with the Company.

7.3        Because  of  the  difficulty  of  measuring  economic  losses  to  the  Company  as  a  result  of  a  breach  or
threatened  breach  of  the  covenants  set  forth  in Article VI  and  in  this  Article VII,  and  because  of  the  immediate  and
irreparable  damage  that  would  be  caused  to  the  Company  for  which  they  would  have  no  other  adequate  remedy,  the
Company  shall  be  entitled  to  enforce  the  foregoing  covenants,  in  the  event  of  a  breach  or  threatened  breach,  by
injunctions and restraining orders from any court of competent jurisdiction, without the necessity of showing any actual
damages or that money damages would not afford an adequate remedy, and without the necessity of posting any bond
or  other  security. The aforementioned equitable relief shall not be the Company’s exclusive remedy for a breach but
instead shall be in addition to all other rights and remedies available to the Company at law and equity.

7.4    The covenants in this  Article VII, and each provision and portion hereof, are severable and separate, and
the unenforceability of any specific covenant (or portion thereof) shall not affect the provisions of any other covenant
(or  portion  thereof). Moreover,  in  the  event  any  arbitrator  or  court  of  competent  jurisdiction  shall  determine  that  the
scope,  time  or  territorial  restrictions  set  forth  are  unreasonable,  then  it  is  the  intention  of  the  parties  that  such
restrictions be enforced to the fullest extent which such arbitrator or court deems reasonable, and this Agreement shall
thereby be reformed.

7.5    The following terms shall have the following meanings:

a.

b.

c.

d.

“Business”  shall mean the business and operations that are the same or similar to those performed by
the  Company  for  which  Quarles  provides  services  or  about  which  Quarles  obtains  Confidential
Information during his employment.

cooperation in connection with any action or proceeding (or any appeal from any action or proceeding) which relates to
events occurring during his employment hereunder, provided that the Company shall reimburse him for his reasonable
costs  and  expenses  and  such  cooperation  shall  not  unreasonably  burden  him  or  unreasonably  interfere  with  any
subsequent employment that Quarles may undertake. In the event the Company requires Quarles to devote significant
time to post-separation cooperation and at the time of such post-separation cooperation Quarles is no longer receiving
severance benefits hereunder, the Company shall establish in good faith an hourly or daily rate based on his Base Salary
(as  in  effect  on  the  date  of  termination  of  his  employment)  to  compensate  Quarles  for  his  time  expended  at  the
Company’s request.

permitted  by,  all  applicable  laws,  ordinances,  rules,  and  regulations. In  the  event  any  provision  of  this Agreement  is
held  to  be  invalid,  illegal,  or  unenforceable  for  any  reason  and  in  any  respect,  and  the  basis  of  the  bargain  of  this
Agreement is not thereby destroyed, such invalidity, illegality, or unenforceability shall not affect the remainder of this
Agreement,  which  shall  be  and  remain  in  full  force  and  effect,  enforceable  in  accordance  with  its  terms. The  Parties
agree  to  negotiate  in  good  faith  to  replace  such  invalid,  illegal  and  unenforceable  provision  with  a  valid,  legal  and
enforceable  provision  that  achieves,  to  the  greatest  lawful  extent  under  this Agreement,  the  economic,  business  and
other purposes of such invalid, illegal or unenforceable provision.

8 . 8    Divisions  and  Headings.  The  divisions  of  this Agreement  into Articles  and  Sections  and  the  use  of
captions and headings in connection therewith are solely for convenience and shall have no legal effect in construing
the  provisions  of  this  Agreement. All  references  herein  to  Articles,  Sections  or  other  subdivisions  refer  to  the
corresponding Article, Section or other subdivision of this Agreement unless specific reference is made to such articles,
sections or other subdivisions of another document or instrument.

8 . 9     Interpretation. Whenever required by the context, gender shall include any other gender, singular shall
include  plural,  and  the  plural  shall  include  singular. The  words  “this Agreement,”  “hereof,”  “herein,”  “hereto,”  and
“hereunder” refer to this Agreement as a whole and not to any particular provision of this Agreement unless expressly
so limited. The words “include,” “includes,” and “including” are deemed to be followed by “without limitation”.

8 . 1 0    Counterparts.  The  Parties  may  execute  this  Agreement  in  multiple  counterparts,  each  of  which
constitutes  an  original  as  against  the  Party  that  signed  it,  and  all  of  which  together  constitute  one  agreement. This
Agreement is effective upon delivery of one executed counterpart from each Party to the other Parties. The signatures
of all Parties need not appear on the same counterpart. The delivery of signed counterparts by email transmission that

includes a copy of the sending party’s signature(s) is as effective as signing and delivering the counterpart in person.

8.11     Entire Agreement/Amendment. This Agreement supersedes all previous contracts, and constitutes the
entire agreement of whatsoever kind or nature existing between or among the Parties respecting the subject matter. No
Party shall be entitled to benefits other than those specified herein. As between the Parties, no oral statements or prior
written  material  not  specifically  incorporated  herein  shall  be  of  any  force  and  effect.  The  Parties  specifically
acknowledge that, in entering into and executing this Agreement, each is relying solely upon the representations and
agreements contained in this Agreement and no others. All prior representations or agreements, whether written or oral,
not expressly incorporated herein, are superseded and no changes in or additions to this Agreement shall be recognized
unless and until made in writing and signed by all Parties. This Agreement may not be changed, revised or modified
unless by mutual consent and in writing, signed by both Parties.

8.12    Effect of Terminations . Termination of Quarles’ employment under this Agreement shall not affect any
right or obligation of a Party which is accrued or vested prior to such termination. Without limiting the scope of the
preceding  sentence,  the  provisions  of Article  VI,  Article  VII,  and  this  Article  VIII  that  by  their  terms  survive  the
termination of Quarles’ employment with the Company shall survive any termination of the employment relationship
and/or of this Agreement.

8.13    Actions by the Board . Any and all determinations or other actions required of the Board hereunder that
relate  specifically  to  Quarles’  employment  with  the  Company  or  the  terms  and  conditions  of  such  employment  and
Quarles’ appointment as an officer or director of the Company and its affiliates shall be made by the members of the
Board other than Quarles if Quarles is a member of the Board, and Quarles shall not have any right to vote, participate
or decide upon any such matter.

8.14    Changes Due to Compliance with Applicable Law . Quarles understands that certain laws, as well as
rules and regulations promulgated by the Securities and Exchange Commission (including without limitation under the
Dodd-Frank  Wall  Street  Reform  and  Consumer  Protection  Act  and  the  Sarbanes-Oxley  Act  of  2002)  and/or  by
securities exchanges, do and will require the Company to recoup, and Quarles to repay, incentive compensation payable
hereunder under the circumstances set forth under such laws, rules and regulations. Such requirements will be set forth
from  time  to  time  in  policies  adopted  by  the  Company  (so-called  “clawback”  policies),  and  Quarles  acknowledges
receipt of the Company’s current clawback policy.  Quarles acknowledges that amounts paid or payable pursuant to this
Agreement  as  incentive  compensation  or  otherwise  by  the  Company  shall  be  subject  to  clawback  to  the  extent
necessary  to  comply  with  such  laws,  rules,  regulations  and/or  policy,  which  clawback  may  include  forfeiture,
repurchase  and/or  recoupment  of  amounts  paid  or  payable  hereunder,  and  Quarles  agrees  to  repay  such  amounts
(whether or not still employed by the Company or any of its affiliates), as required by such laws, rules, regulations or
policy. Quarles shall repay the Company in cash in immediately available funds within 60 days of demand for payment
by  the  Company  or  as  otherwise  agreed  by  the  Company  in  its  sole  discretion. Any  such  clawback  shall  not  provide
Quarles any termination rights or other rights to payment under this Agreement, nor constitute a breach or violation of
this  Agreement  by  the  Company.  Quarles  hereby  consents  to  any  changes  to  the  current  policy  that  are  adopted  to
comply  with  applicable  law,  rules  or  regulations  (including  by  securities  exchanges)  or  otherwise  approved  by  the
Board. Further, if determined necessary or appropriate by the Board, Quarles agrees to enter into an amendment to this
Agreement  or  a  separate  written  agreement  with  the  Company  to  comply  with  such  laws,  rules  and  regulations
thereunder if required thereby or determined appropriate by the Board in its reasonable discretion.

8.15    Code Section 409A.

The Parties intend that this Agreement and the benefits provided hereunder be interpreted and construed to be
exempt  from  or  to  otherwise  comply  with  Code  Section  409A  to  the  extent  applicable  thereto. Notwithstanding  any
provision  of  this Agreement  to  the  contrary,  this Agreement  shall  be  interpreted  and  construed  consistent  with  this
intent, provided  that  the  Company  shall  not  be  required  to  assume  any  increased  economic  burden  in  connection
therewith. Although  the  Company  intends  to  administer  this Agreement  so  that  it  will  be  exempt  from,  or  otherwise
comply with the requirements of Code Section 409A, the Company does not represent or warrant that this Agreement
will be exempt from or otherwise comply with Code Section 409A, or any other provisions of federal, state, local, or
non-United  States  laws. Neither  the  Company,  its  affiliates,  nor  their  respective  directors,  officers,  employees  or
advisors  shall  be  liable  to  Quarles  (or  any  individual  claiming  a  benefit  through  Quarles)  for  any  tax,  interest,  or
penalties that Quarles may owe as a result of compensation or benefits paid under this Agreement, and the Company,
its  affiliates  and  their  respective  directors,  officers,  employees  or  advisors  shall  have  no  obligation  to  indemnify,
reimburse,  or  otherwise  protect  Quarles  from  the  obligation  to  pay  any  taxes  pursuant  to  Code  Section  409A  or
otherwise.

Notwithstanding any provision of this Agreement to the contrary, in the event that any payment to Quarles or
any benefit hereunder is made upon, or as a result of Quarles’ termination of employment, and Quarles is a “specified
employee” (as that term is defined under Code Section 409A) at the time Quarles becomes entitled to any such payment
or benefit, and provided further that such payment or benefit does not otherwise qualify for an applicable exemption

from Code Section 409A, then no such payment or benefit shall be paid or commenced to be paid to Quarles under this
Agreement  until  the  date  that  is  the  earlier  to  occur  of:  (i)  Quarles’  death,  or  (ii)  six  (6)  months  and  one  (1)  day
following  his  termination  of  employment  (the  “Delay  Period”). Any  payments  which  Quarles  would  otherwise  have
received during the Delay Period shall be payable to Quarles in a lump sum on the date that is six (6) months and one
(1)  day  following  the  effective  date  of  the  termination. For  purposes  of  this  Agreement,  the  terms  “terminate,”
“termination,” “termination of employment,” and variations thereof as used in this Agreement, are intended to mean a
termination  of  employment  that  constitutes  a  “separation  from  service”  as  such  term  is  defined  under  Code  Section
409A.

Any  reimbursements  by  the  Company  to  Quarles  of  any  eligible  expenses  under  this Agreement,  other  than
reimbursements  that  would  otherwise  be  exempt  from  income  or  the  application  of  Code  Section  409A,
(“Reimbursements”)  will  be  made  promptly  and,  in  any  event,  on  or  before  the  last  day  of  Quarles’  taxable  year
following his taxable year in which the expense was incurred. The  amount  of  any  Reimbursements,  and  the  value  of
any in-kind benefits to be provided to Quarles under this Agreement, other than in-kind benefits that would otherwise
be exempt from income or the application of Code Section 409A, during any of Quarles’ taxable years will not affect
the expenses eligible for reimbursement, or in-kind benefits to be provided, in any other of his taxable years, except for
any limit on the amount of expenses that may be reimbursed under an arrangement described in Code Section 105(b).
The right to Reimbursements, or in-kind benefits, will not be subject to liquidation or exchange for another benefit.

8.16    Federal Excise Tax Under Section 4999 of the Code .

(a)     Treatment  of  Excess  Parachute  Payments .    In  the  event  that  any  benefits  payable  to  Quarles
pursuant  to  this  Agreement,  either  alone  or  in  conjunction  with  other  compensatory  payments  (“Payments”)  (i)
constitute “parachute payments” within the meaning of Code Section 280G, and (ii) but for this Section 8.16 would be
subject to the excise tax imposed by Code Section 4999, or any comparable successor provisions (the “Excise Tax”),
then the Payments hereunder shall be either (a) provided to Quarles in full, or (b) provided to Quarles as to such lesser
extent which would result in no portion of such benefits being subject to the Excise Tax, whichever of the foregoing
amounts,  when  taking  into  account  applicable  federal,  state,  local  and  foreign  income  and  employment  taxes,  the
Excise  Tax,  and  any  other  applicable  taxes,  results  in  the  receipt  by  Quarles,  on  an  after-tax  basis,  of  the  greatest
amount of benefits, notwithstanding that all or some portion of such benefits may be taxable under the Excise Tax.  In
the event of a reduction of benefits hereunder, the Accountants (as defined below) shall determine which benefits shall
be  reduced  so  as  to  achieve  the  principle  set  forth  in  the  preceding  sentence.    In  no  event  shall  the  foregoing  be
interpreted or administered so as to result in an acceleration of payment or further deferral of payment of any amounts
(whether under this plan or any other plan) in violation of Code Section 409A.

(b)     Determination of Amounts .  All computations and determinations called for by this  Section 8.16
shall be promptly determined and reported in writing to the Company and Quarles by independent public accountants
or  other  independent  advisors  selected  by  the  Company,  and  all  such  computations  and  determinations  shall  be
conclusive and binding upon Quarles and the Company.  For the purposes of such determinations, the Accountants may
rely  on  reasonable,  good  faith  interpretations  concerning  the  application  of  Code  Sections  280G  and  4999.  The
Company  and  Quarles  shall  furnish  to  the  Accountants  such  information  and  documents  as  the  Accountants  may
reasonably  request  in  order  to  make  their  required  determinations.    The  Company  shall  bear  all  fees  and  expenses
charged by the Accountants in connection with such services.

(c)    Potential Further Reduction of Benefits .  If, notwithstanding any reduction described in this  Section
8.16 the Internal Revenue Service (“IRS”) determines that Quarles is liable for the Excise Tax as a result of the receipt
of  any  Payments,  then  Quarles  shall  be  obligated  to  pay  back  to  the  Company,  within  30  days  after  a  final  IRS
determination  or  in  the  event  that  Quarles  challenges  the  final  IRS  determination,  a  final  judicial  determination,  a
portion  of  the  Payments  equal  to  the  “Repayment  Amount.”    The  Repayment  Amount  shall  be  the  smallest  such
amount, if any, as shall be required to be paid to the Company so that Quarles' net after-tax proceeds with respect to the
Payments  (after  taking  into  account  the  payment  of  the  Excise  Tax  and  all  other  applicable  taxes  imposed  on  such
benefits) shall be maximized.  The Repayment Amount shall be zero if a Repayment Amount of more than zero would
not result in Quarles' net after-tax proceeds with respect to the Payments being maximized.  If the Excise Tax is not
eliminated pursuant to this Section 8.16, Quarles shall pay the Excise Tax.

(d)    Potential Increase in Benefits .  Notwithstanding any other provision of this  Section 8.16, if (i) there
is a reduction in the payments to Quarles as described in this Section 8.16, (ii) the IRS later determines that Quarles is
liable  for  the  Excise  Tax,  the  payment  of  which  would  result  in  the  maximization  of  Quarles'  net  after-tax  proceeds
(calculated  as  if  Quarles'  benefits  had  not  previously  been  reduced),  and  (iii)  Quarles  pays  the  Excise  Tax,  then  the
Company shall pay to Quarles those payments which were reduced pursuant to this Section 8.16, within 30 days after
Quarles pays the Excise Tax so that Quarles' net  after-tax  proceeds  with  respect  to  the  payment  of  the  Payments  are
maximized.

(e)     As  expressly  permitted  by  Q/A  #32  of  the  Code  Section  280G  regulations,  with  respect  to

performing  any  present  value  calculations  that  are  required  in  connection  with  this Section  8.16,  Quarles  and  the
Company each affirmatively elect to utilize the Applicable Federal Rates (“AFR”) that are in effect as of the restatement
date and the Accountants shall therefore use such AFRs in their determinations and calculations.   The Company shall
pay the fees and costs of the Accountants that are incurred in connection with this Section 8.16.

8.17    Construing Agreement. If a dispute arises between the Parties over the meaning or application of this
Agreement,  then  this Agreement  is  to  be  construed  fairly  and  reasonably  and  neither  more  strongly  for  nor  against
either Party. Each Party acknowledges that it has been represented by counsel of its choice throughout all negotiations
that  have  preceded  the  execution  of  this  Agreement  and  that  it  has  executed  the  same  with  the  advice  of  said
independent counsel. Each Party and its counsel cooperated in the drafting and preparation of this Agreement and the
documents  referred  to  herein,  and  any  and  all  drafts  relating  thereto  exchanged  between  the  Parties  shall  be  deemed
jointly drafted by the Parties and may not be construed against any Party by reason of its preparation. Accordingly any
rule of Law or any legal decision that would require interpretation of any ambiguities in this Agreement against any
Party that drafted it is of no application and is hereby expressly waived.

SEPARATION AND RELEASE AGREEMENT

EXECUTION VERSION

This Separation and Release Agreement (this “ Agreement”) is made and entered into by and between Simon
Upfill-Brown,  an  individual,  on  behalf  of  himself,  his  spouse,  agents,  representatives,  attorneys,  assigns,  heirs,
executors,  administrators,  beneficiaries  and  trustees  (“Employee”),  and  Trecora  Resources  on  behalf  of  itself,  and  its
respective  predecessors,  successors,  all  former,  current  and  future  related  or  affiliated  companies,  divisions,
subsidiaries,  affiliates  and  parents,  and,  collectively,  its  former,  current  and  future  directors,  officers,  employees,
agents,  representatives,  equity  owners,  attorneys,  fiduciaries,  assignees,  heirs,  executors,  administrators,  beneficiaries
and trustees (collectively the “Company”). Employee and the Company are referenced collectively as the “Parties.”

Whereas, the Company has employed Employee and the Parties are desirous of terminating their   employment

relationship under certain terms and conditions as follows:

1.Separation of Employment; Deemed Resignations : The Parties agree that Employee’s separation of employment is
effective as of December 3, 2018 (the “Separation Date”). As of the Separation Date, Employee shall be deemed to
have resigned, to the extent applicable, as an officer of the Company and any affiliate of the Company, and as a
member  of  the  board  of  directors  and/or  similar  governing  body  of  the  Company  and  any  of  the  Company’s
affiliates. For  purposes  of  this  paragraph  1,  “affiliate”  shall  include  Texas  Oil  &  Chemical  Co.  II,  Inc.,  South
Hampton Resources, Inc., Gulf State Pipe Line Co, Inc., Trecora Chemical, Inc. and Al Masane Al Kobra Mining
Company.

2.Payment: In consideration of the releases and other consideration described in this Agreement, the Company agrees
to  pay  Employee  an  amount  equal  to  18  months  of  salary  ($780,000),  less  lawful  withholdings  (which  for  the
avoidance  of  doubt  will  be  calculated  in  the  same  manner  as  withholderings  were  calculated  during  Employee’s
employment by the Company in 2018) and deductions (the “Cash Consideration ”). The Company will also provide
the additional consideration described on Attachment 1 (the “Additional Consideration”). The Cash Consideration
and  Additional  Consideration  are  collectively  referred  to  in  this  Agreement  as  the  “ Consideration” . The  Cash
Consideration  and  item  (4)  of  the  Additional  Consideration  will  be  paid  in  accordance  with  the  Company’s
customary payroll practices, the requirements of applicable law, and will be subject to any applicable payroll and
income  tax  withholding  and  other  typical  deductions,  as  will  the  cash  value  of  item  (1)  of  the  Additional
Consideration.

Payment of the Cash Consideration shall be made in January 2019. Item (4) of the Additional Consideration will
be payable to Employee no later than February 15, 2019. The Additional Consideration (other than item (4) of
the Additional Consideration) will be provided to Employee after the Effective Date and within the time frame
contemplated in Attachment 1.

Notwithstanding anything herein to the contrary, in the event Employee dies, the Company’s obligations under
this Agreement shall not cease, and Employee’s estate shall be entitled to all Consideration to which Employee is
or would have been entitled to under this Agreement.

3.General  Release:  For  and  in  consideration  of  the  payments  and  promises  set  forth  above  and  other  good  and
valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Employee hereby releases,
acquits, and forever discharges the Company and all parents, subsidiaries, affiliates, partners, joint venturers, equity
owners, and shareholders, and each of their respective officers, directors, employees, representatives, attorneys, and
agents, and all successors and assigns thereof (collectively referred to as the “Released Parties”), from any and all
claims,  charges,  complaints,  demands,  liabilities,  obligations,  promises,  agreements,  controversies,  damages,
actions, causes of action, suits, rights, entitlements, costs, losses, debts, and expenses (including attorneys’ fees and
legal expenses), of any nature whatsoever, known or unknown, fixed or contingent, which Employee now has, had,
or  may  hereafter  claim  to  have  had  against  the  Company  or  any  of  the  Released  Parties,  of  any  kind  or  nature
whatsoever, arising from any act, omission, transaction, matter, or event which has occurred or is alleged to have
occurred  up  to  the  date  this  Agreement  is  executed  by  Employee. This  release  includes,  without  limitation,  a
knowing and voluntary waiver of all claims relating in any way to Employee’s employment with the Company or
the  conclusion  of  that  employment,  whether  such  claims  are  now  known  or  are  later  discovered. The  claims
knowingly and voluntarily waived by Employee include, without limitation, all claims, causes of action, or disputes
arising  out  of  or  related  to: (i) Employee’s employment or separation of employment with the Company; and (ii)
any  other  disputes  or  claims,  known  or  unknown,  fixed  or  contingent,  that  existed  or  exist  at  law  or  equity  or
sounding  in  contract  (express  or  implied)  or  tort,  known  or  unknown,  fixed  or  contingent,  that  existed  or  exist
among the Employee, the Company and the Released Parties arising under any federal, state, or local laws of any
jurisdiction  that  prohibit  age,  sex,  race,  national  origin,  color,  disability,  religion,  veteran,  military  status,  sexual
orientation, genetic information or any other form of discrimination, harassment, or retaliation (including, without

limitation, the Americans with Disabilities Act, Title VII of the 1964 Civil Rights Act, Section 1981 of the Civil
Rights Act, the Civil Rights Act of 1991, the Rehabilitation Act, the Family and Medical Leave Act, the Employee
Polygraph  Protection  Act,  the  Uniformed  Services  Employment  and  Reemployment  Rights  Act,  the  Genetic
Information  Nondiscrimination Act,  the  Texas  Commission  on  Human  Rights Act  (Texas  Labor  Code)),  claims
relating to breach of contract, breach of any implied covenant of good faith and fair dealing, wrongful termination,
wrongful demotion, intentional or negligent infliction of emotional distress, interference with contractual relations
or economic advantage, defamation, misrepresentation, benefits, penalties, fees, costs, expenses, or any other claim
relating  to  or  arising  out  of  his  employment  with  the  Company  or  any  other  federal,  state,  or  local  laws  of  any
jurisdiction, claims arising under the Employee Retirement Income Security Act, or any other statutory or common
law claims arising on or before the date this Agreement is executed by Employee; provided, however, that nothing
in this Agreement shall be interpreted to release any claims which Employee may have for workers’ compensation
benefits or any entitlement to employee benefits in which Employee already is vested as of the date this Agreement
is executed by Employee. Furthermore, nothing in this Agreement shall be interpreted to release any claims which
Employee may have in the future that accrue after the Effective Date. In addition to the other acknowledgments in
this  Agreement,  Employee  acknowledges  that  this  Agreement  may  be  pled  as  a  complete  defense  and  shall
constitute  a  full  and  final  bar  to  any  claim  for  damages  or  other  relief  based  on  any  act,  omission,  transaction,
matter,  or  event  which  has  occurred  or  is  alleged  to  have  occurred  up  to  the  date  this Agreement  is  executed  by
Employee.

4.Release  of Age  Discrimination  Claims : Also  included  among  the  claims  knowingly  and  voluntarily  waived  and
released  by  Employee  pursuant  to  this Agreement  are  any  and  all  age  discrimination,  retaliation,  harassment,  or
related  claims  under  the Age  Discrimination  in  Employment Act  (“ ADEA”),  the  Texas  Commission  on  Human
Rights  Act,  the  Older  Workers  Benefit  Protection  Act  (“ OWBPA”),  or  any  other  federal,  state,  or  local  law.

which  Employee  became  aware  through  employment  with  the  Company  or  any  of  its  affiliates,  or  which  may

constitute legally privileged information owned by the Company, including, without limitation, the identity of and
any  information  related  to  the  customers  and  suppliers  of  the  Company  (the  “Confidential  Information”).
Employee  covenants  that  he  shall  not  at  any  time,  without  the  Company’s  prior  written  consent,  directly  or
indirectly  use,  give,  sell,  transfer,  transmit,  or  disclose  any  Confidential  Information  for  any  purpose.  This
provision is in addition to, and not in lieu of: (a) the protections afforded trade secrets and confidential information
under  applicable  law;  and  (b)  the  restrictions  on  use  or  disclosure  of  trade  secrets,  confidential  information,  or
proprietary  information  under  any  other  confidentiality  agreement  between  the  Company  and  Employee.
Employee’s confidentiality duty does not apply to information that is (i) in the public domain or becomes part of
the public domain through no fault of Employee or (ii) was known by Employee prior to Employee’s association
with the Company, as evidenced by written records existing at that time.

7.Non-Disclosure: Employee covenants and agrees that he will not disclose the existence or terms of this Agreement
to any person except his spouse and: (a) licensed attorney(s) for the purpose of obtaining legal advice; (b) licensed
or  certified  accountant(s)  for  the  purpose  of  preparing  tax  returns  or  other  financial  services;  (c)  in  formal
proceedings  to  enforce  the  terms  of  this  Agreement;  or  (d)  as  required  by  law  or  court  order,  provided  that

shall afford sufficient time for the Company to intervene or take action as appropriate.

8.Non-Disparagement: Employee covenants and agrees not to make any intentional statement, oral or written, or to
perform any intentional act or omission for the purpose of causing, or reasonably expected to cause, any material
harm to the Company’s business, business relationships, operations, goodwill, or reputation. The Company agrees
that its officers and directors shall not make any intentional statement, oral or written, or perform any intentional
act or omission for the purpose of causing, or reasonably expected to cause, any material harm to the Employee,
Employee’s business relationships, or Employee’s reputation. This provision is in addition to, and not in lieu of,
the substantive protections under applicable law relating to defamation, libel, slander, interference with contractual
or business relationships, or other statutory, contractual, or tort theories. In response to any inquiries made to the

9.Return  of  Property:  Employee  agrees  that  by  the  date  Employee  executes  this  Agreement,  unless  otherwise
expressly  agreed  to  in  writing  by  the  Parties,  he  shall  return  to  the  Company  all  Company  property,  including,
without  limitation,  computers,  software,  designs,  drawings,  credit  cards,  keys,  trucks  or  automobiles,  pagers,
equipment, tools, security access cards, books, records, forms, specifications, formulae, data, processes, papers and
writings (including but not limited to electronic documents) related to the business of the Company, together with

Company, or any of its affiliates. Notwithstanding the foregoing, Employee shall retain the cellular phone and iPad
in  his  possession,  and  he  shall  be  permitted  to  retain  the  corresponding  cellular  phone  number  that  has  been
utilized by Employee during his employment; provided that the Company shall have the opportunity to inspect the
cellular phone and iPad and remove any Company property.

10.Insider Trading:  Employee  agrees  that  after  the  Separation  Date  he  remains  subject  to  the  Company’s  Insider
Trading Policy and other Company policies and procedures relating to insider trading, including restrictions on
trading  outside  of  designated  window  periods. If  the  Separation  Date  falls  during  an  open  window  period,  the
Employee is free to trade; however, if the Separation Date falls during blackout periods the Employee must wait
to  trade  until  the  next  window  period  opens. The  above  provisions  of  this  paragraph  10  will  expire  on  the  six-
month anniversary of the Effective Date. If Employee has a question about whether a blackout period is in effect
during  such  six-month  period,  he  may  contact  the  Company. This  paragraph  10  is  subject,  of  course,  to  the
general prohibitions under US securities laws on trading listed securities if any person, including the Employee is
in possession of material non-public information.

11.Protected Rights: Employee understands this Agreement does not release any claims that cannot be released as a
matter  of  law.  Employee further understands no section in this Agreement is intended to or shall limit, prevent,
impede or interfere with his non-waivable right, without prior notice to the Company, to provide information to
the  government,  participate  in  investigations,  testify  in  proceedings  regarding  the  Company’s  past  or  future
conduct,  or  engage  in  any  activities  protected  under  whistleblower  statutes,  or  to  receive  and  fully  retain  a
monetary  award  from  a  government-administered  whistleblower  award  program  for  providing  information
directly to a government agency. Notwithstanding the above, unless otherwise prohibited by law, by signing this
Agreement,  Employee  releases  and  waives  his  right  to  claim  or  recover  monetary  damages  directly  from  the
Company in any charge, complaint, or lawsuit filed by Employee or by anyone else on Employee’s behalf, for
any released claims.

Employee  also  understands  that  pursuant  to  the  Defend  Trade  Secrets  Act  of  2016,  he  shall  not  be  held
criminally, or civilly, liable under any Federal or State Trade secret law for the disclosure of a trade secret that is
made in confidence either directly or indirectly to a Federal, State, or local government official, or an attorney,

for  the  sole  purpose  of  reporting,  or  investigating,  a  violation  of  law. Moreover,  Employee  understands
employees may disclose trade secrets in a complaint, or other document, filed in a lawsuit, or other proceeding, if
such  filing  is  made  under  seal. Finally,  Employee  understands  an  employee  who  files  a  lawsuit  alleging
retaliation  by  the  company  for  reporting  a  suspected  violation  of  the  law  may  disclose  the  trade  secret  to  the
attorney  of  the  employee  and  use  the  trade  secret  in  the  court  proceeding,  if  the  employee  files  any  document
containing the trade secret under seal and does not disclose the trade secret, except pursuant to court order.

12.Entire Agreement: This Agreement constitutes the final and entire agreement between the Parties with respect to
the subject matter herein, and no other representation, promise, or agreement has been made to cause Employee to
sign this Agreement.

13.Governing  Law  and  Forum:  This  Agreement  shall  be  deemed  to  be  made  in,  and  in  all  respects  shall  be
interpreted,  construed,  and  governed  by  and  in  accordance  with  the  laws  of  the  State  of  Texas,  notwithstanding
any choice of law provisions otherwise requiring application of other laws. In  the  event  of  litigation  concerning
this Agreement,  the  Parties  agree  to  the  jurisdiction  of  federal  and  state  courts  in  Harris  County,  Texas.  EACH
PARTY HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE
LAW,  ANY  OBJECTION  TO  PERSONAL  JURISDICTION,  WHETHER  ON  GROUNDS  OF  VENUE,
RESIDENCE OR DOMICILE.

14.Assignment: This Agreement and Employee’s rights and obligations under it may not be assigned or delegated at

Company’s sole and absolute discretion.

normal rule of construction to the effect that any ambiguities are to be resolved against the drafting party shall not
be  employed  in  the  interpretation  of  this  Agreement. The  language  of  this  Agreement  shall,  in  all  cases,  be
construed as a whole, according to its fair meaning, and not strictly for, or against, either of the Parties.

separate, severable, and divisible. If any term, provision, covenant, restriction, or condition of this Agreement or
part  thereof,  or  the  application  thereof  to  any  person,  place,  or  circumstance,  shall  be  held  to  be  invalid,
unenforceable,  or  void,  the  remainder  of  this Agreement  and  such  term,  provision,  covenant,  or  condition  shall
remain  in  full  force  and  effect  to  the  greatest  extent  practicable  and  permissible  by  law,  and  any  such  invalid,
unenforceable, or void term, provision, covenant, or condition shall be deemed, without further action on the part
of  the  Parties  hereto,  modified,  amended,  limited,  or  deleted  to  the  extent  necessary  to  render  the  same  and  the
remainder of this Agreement valid, enforceable, and lawful.

17.Modification: This Agreement can only be modified in a writing executed in the same manner as this Agreement.

18.Acknowledgments: Employee  acknowledges  and  agrees  that  the  Company  has  not  made  any  representations  to
Employee regarding the tax consequences of any amounts or benefits received by Employee under this Agreement
and further agrees that Employee shall be solely responsible for payment of all personal tax liabilities due on any
and all payments to Employee under this Agreement, including, without limitation, federal, state and local taxes,
and  interest  and  penalties,  which  are  or  may  become  due. Employee  acknowledges  and  agrees  that  the
Consideration  constitutes  consideration  that  is  in  addition  to  anything  of  value  to  which  Employee  would  have
been  entitled  absent  his  signing  and  not  timely  revoking  this  Agreement,  and  that  other  than  through  this
Agreement,  Employee  is  not  otherwise  entitled  to  the  Consideration. Employee  has  read  this  Agreement  and
understands its terms. Employee has been provided with a full and fair opportunity to consult with an attorney of
Employee’s  choosing  and  to  obtain  any  and  all  advice  deemed  appropriate  with  respect  to  this  Agreement.
Employee  acknowledges  that  nothing  in  this  Agreement  shall  limit  Employee’s  ability  to  confer  with  legal
counsel,  to  testify  truthfully  under  subpoena  or  court  order,  or  to  initiate,  provide  truthful  information  for,  or
cooperate with an investigation by a municipal, state, or federal agency for enforcement of laws. This Agreement
has been entered into with the understanding that there are no unresolved claims of any nature that Employee has
against  the  Company. Employee  acknowledges  and  agrees  that  except  for  the  Consideration,  all  compensation,
benefits, and other obligations due Employee by the Company, whether by contract or by law, have been paid or
satisfied in full. Employee further agrees that the representations and understandings set forth in this paragraph 18
have been relied on by the Company and constitute consideration for the Company’s execution of this Agreement.
In  light  of  the  foregoing,  Employee  is  satisfied  with  the  terms  of  this Agreement  and  agrees  that  its  terms  are
binding on him.

19.Headings: The headings of paragraphs in this Agreement are for convenience of reference only and shall not affect

the construction or interpretation of this Agreement

20.Counterparts: This Agreement may be executed in any number of counterparts, which shall together constitute one

agreement. Any  Party  may  enter  into  this Agreement  by  signing  any  such  counterpart.  The  delivery  of  signed
counterparts  by  e-mail  transmission  that  includes  a  copy  of  the  sending  Party’s  signature(s)  is  as  effective  as
signing and delivering the counterpart in person.

21.Code Section 409A : The Parties intend that this Agreement and the benefits provided hereunder be interpreted and
construed  to  be  exempt  from  or  to  otherwise  comply  with  Internal  Revenue  Code  Section 409A  to  the  extent
applicable  thereto. Notwithstanding  any  provision  of  this  Agreement  to  the  contrary,  this  Agreement  shall  be
interpreted and construed consistent with this intent, provided that the Company shall not be required to assume
any  increased  economic  burden  in  connection  therewith. Although  the  Company  intends  to  administer  this
Agreement so that it will be exempt from or otherwise comply with the requirements of Code Section 409A, the
Company does not represent or warrant that this Agreement will be exempt form or otherwise comply with Code
Section 409A or any other provision of federal, state, local, or non-United States law.  Neither the Company, its
affiliates, nor their respective directors, officers, employees or advisers shall be liable to Employee (or any other
individual claiming a benefit through Employee) for any tax, interest, or penalties Employee may owe as a result
of  compensation  or  benefits  paid  under  this  Agreement,  and  the  Company,  its  and  affiliates  their  respective
directors, officers, employees and advisers shall have no obligation to indemnify or otherwise protect Employee
from the obligation to pay any taxes pursuant to Code Section 409A or otherwise. Each separate payment of the
Cash Consideration and the Additional Consideration will be considered a separate payment for purposes of Code
Section 409A. The amount of any in-kind benefits to be provided to Employee under this Agreement, other than
in-kind benefits that would otherwise be exempt from income or the application of Code Section 409A, during any
of Employee’s taxable years will not affect the in-kind benefits to be provided, in any other of his taxable years.
The right to in-kind benefits, will not be subject to liquidation or exchange for another benefit.

22.Further Cooperation:  Employee  shall  provide  accurate  information  or  testimony  or  both  in  connection  with  any
legal  matters,  if  so  requested  by  the  Company.  Employee  shall  make  himself  available  upon  request  to  provide
information  and/or  testimony,  in  a  formal  and/or  informal  setting  in  accordance  with  the  Company’s  request,
subject  to  reasonable  accommodation  of  your  schedule  and  reimbursement  of  reasonable  documented  expenses
incurred  by  Employee,  including  reasonable  and  necessary  attorney  fees  (if  independent  legal  counsel  is
reasonably necessary).

23.Special  Remedies:  Employee  acknowledges  that  a  breach  or  threatened  breach  by  Employee  of  the  terms  of
paragraphs 6, 7 or 8 of this Agreement would result in material and irreparable injury to the Company, and that it
would  be  difficult  or  impossible  to  establish  the  full  monetary  value  of  such  damage.  Therefore,  the  Company
shall be entitled to injunctive relief in the event of any such breach or threatened breach without the posting of any
bond in connection therewith.

EXECUTION VERSION

AMENDED AND RESTATED CONSULTING AGREEMENT

This  Consulting  Agreement  (this  “Agreement”)  is  entered  into  this  14th  day  of  December  2018  by  and  between
Trecora Resources (“Trecora”), a Delaware corporation, and  Nicholas N. Carter (“Carter”), a Texas resident. Trecora
and Carter are sometimes referred to herein individually as a “Party” and collectively as the “Parties.”

RECITALS

A.        The  Parties  entered  into  that  certain  Consulting  Agreement  dated  effective  March  20,  2018  (the  “Original
Agreement”) pursuant to which Carter agreed to provide certain consulting services to Trecora.

B.        The  Parties  now  desire  to  amend  and  restate  the  terms  of  the  Original  Agreement  in  its  entirety  with  this
Agreement.

AGREEMENT

NOW, THEREFORE, in consideration of the mutual promises, representations, warranties, covenants, conditions and
agreements  contained  herein,  and  for  other  valuable  consideration,  the  receipt  and  sufficiency  of  which  are  hereby
acknowledged, the Parties agree as follows:

1.        Carter’s  Services.  Trecora  retains  Carter,  as  an  independent  contractor,  to  provide  certain  consulting  services
related to Trecora’s investment in Al Masane Al Kobra Mining Company (AMAK) and other areas as may be mutually
agreed upon (“Consulting Services”). The Parties acknowledge that Carter is a member of Trecora’s Board of Directors
(the  “Board”). Carter’s status as a member of the Board is not addressed under the terms of this Agreement, and this
Agreement has no effect on Carter’s status as a member of the Board.

2.        Consideration.  In  consideration  for  the  Consulting  Services  to  be  performed  by  Carter  under  this Agreement,
Trecora  agrees  to  pay  to  Carter  (1)  a  monthly  fee  of  $7,250.00  in  return  for  Carter’s  provision  of  up  to  40  hours  of
Consulting  Services  per  month,  and  (2)  $5,000  promptly  following  execution  and  delivery  of  this  Agreement. In
addition, Trecora agrees to pay Carter $156.00 for each hour of Consulting Services in excess of 40 hours per month.

Trecora  will  reimburse  Carter  for  all  reasonable  expenses  incurred  by  Carter  in  performing  the  Consulting  Services
provided, however, that any travel related expenses must be approved in advance by the President of Trecora. Carter
shall  submit  written  documentation  and  receipts  to  Trecora  on  a  monthly  basis,  itemizing  the  charges  and  dates  on
which expenses were incurred.

Carter will submit a written invoice to Trecora on a monthly basis for his provision of the Consulting Services. Trecora
shall pay Carter the amounts due pursuant to this Agreement within 30 days after the invoice is received by Trecora. In
the  event  Trecora  disputes  any  portion  of  an  invoice,  Trecora  shall  submit  payment  for  any  undisputed  balance  due
pending resolution of any disputed amounts.

3.    Independent Contractor. Nothing herein shall be construed to create an employer employee relationship between
Trecora and Carter.  Carter is not an employee, servant, partner or agent of Trecora for any purpose whatsoever, and is
not entitled to paid vacation days, sick days, holidays or any other benefits provided to Trecora employees, and is an
independent  contractor  of  the  Company. The  consideration  set  forth  in  Section  2  shall  be  the  sole  consideration  due
Carter for the Consulting Services rendered under this Agreement. Carter will not represent to be or hold himself out as
an employee of Trecora.

4.     Term and Termination.   The term of this Agreement will commence on the date of execution and will end on
December  31,  2019,  and  may  be  extended  by  mutual  agreement  of  the  Parties. Either  party  may  terminate  this
Agreement  for  any  reason  at  any  time  during  the  term  by  written  notice  directed  to  the  other  party  given  30  days  in
advance of the termination date.

5.     Method of Performing Services.  Trecora understands and agrees that Carter shall render Consulting Services in
whatever  manner  deemed  appropriate  by  Carter. During  the  term  of  this  Agreement,  Carter  agrees  to  perform  the
Consulting Services on a professional best-efforts basis, in accordance with all applicable laws and regulations and in
accordance with the highest applicable industry standards.

(a) Trecora shall not control or direct, nor shall Trecora have any right to control or direct, the result of or the details,
methods,  manner  or  means  by  which  Carter  performs  his  business  or  Consulting  Services,  except  that  Carter  shall
coordinate Consulting Services with Trecora, shall provide Consulting Services in accordance with generally accepted
industry standards and in compliance with all international, federal, state, and local laws.

(b)  Carter  has  and  will  at  all  times  retain  the  exclusive  right  to  control  and  direct  the  method,  details,  and  means  of
performing the Consulting Services. Trecora shall not specify the amount of time required to perform individual aspects
of  the  Consulting  Services. Carter’s  services  are  not  exclusive  to  Trecora,  and  Carter  may  render  services  for  other
business entities.

(c)  Any and all personnel hired by Carter, as subcontractors, contractors, employees, consultants, agents or otherwise
(collectively  “Independent  Staff”)  shall  be  the  responsibility  of  Carter.  Carter  will  inform  all  Independent  Staff  in
writing at the time that such Independent Staff are hired by Carter, that such Independent Staff are not employees of
Trecora  and  that  Trecora  has  no  present  or  future  obligation  to  employ  such  Independent  Staff  or  provide  such
Independent Staff with any compensation or employment benefits. Carter will be solely responsible for the acts of such
Independent  Staff,  and  the  Independent  Staff  will  conduct  their  activities  at  Carter’s  risk,  expense  and  supervision.
Carter warrants and covenants that the Independent Staff shall be subject to all of the obligations applicable to Carter
pursuant to this Agreement and that each member of the Independent Staff shall agree to such terms in writing.

(d) Carter agrees to conduct business and supervise his Independent Staff so as to maintain and to increase the goodwill
and reputation of Trecora, and Carter agrees to act in an ethical manner and to conform to and abide by all applicable
laws,  rules,  and  regulations. Carter  agrees  to  indemnify  and  hold  Trecora  harmless  from  any  claims,  lawsuits,
allegations,  or  liability,  including  costs  of  court  and  attorney  fees,  arising  out  of  Carter’s  failure  to  comply  with  any
applicable international, federal, state or local law, regulation, or statute.

6.    Inability to Bind the Company.  Neither Carter nor any of his Independent Staff shall, under any circumstances,
have any authority to act for or to bind Trecora or enter into any agreements, written or otherwise, on behalf of Trecora,
or to sign the name of Trecora or to otherwise represent that Trecora is in any way responsible for his acts or omissions.

7.    Taxes. The Parties agree that Trecora will not withhold, deduct, or pay income tax, social security or other taxes or
amounts for Carter’s benefit or for the benefit of his Independent Staff. Carter is solely responsible for and assumes full
responsibility  for  (as  applicable)  the  payment  of  FICA,  FUTA  and  income  taxes  and  compliance  with  any  other
international,  federal,  state,  or  local  law,  rules  and  regulations.  Carter  is  also  solely  responsible  for  and  assumes  full
responsibility for filing all tax returns, tax declarations and tax schedules, and for the payment of all taxes as required
by  law,  including  without  limitation,  local,  state  and  federal  income  taxes,  Social  Security  taxes,  Medicare  taxes,
unemployment compensation taxes and any other international, federal, state, or local taxes, fees or withholdings due
for him. Carter will be responsible for withholding, accruing and paying all income, social security and other taxes and
amounts  required  by  law  for  all  payments  to  Independent  Staff,  if  any,  as  well  as  all  statutory  insurance  and  other
benefits required by law for Carter and the Independent Staff and all other benefits promised to the Independent Staff
by Carter, if any. Carter agrees to indemnify and hold harmless Trecora from any claims, lawsuits, allegations, or
liability, including costs of court and attorney fees, arising out of Carter’s failure to pay or withhold any taxes or
other required withholdings for Carter or his Independent Staff.

8.    Returning the Company’s Property.  Carter agrees that, on termination of this Agreement, Carter shall return to
Trecora all Confidential Information (as set forth in Section 10) and will deliver to Trecora (and will not keep in his or
their possession, recreate or deliver to anyone else) any and all Trecora property including devices, records, data, notes,
reports,  proposals,  lists,  correspondence,  specifications,  drawings,  blueprints,  sketches,  materials,  equipment,  other
documents or property, or reproductions of any aforementioned items developed during the performance of Consulting
Services for Trecora or otherwise belonging to Trecora.

9.    Intellectual Property. Carter agrees that all inventions, patents, formulas, processes, designs, diagrams, drawings,
flow  charts,  programs,  methods,  apparatus,  software,  firmware,  circuitry,  ideas,  improvements,  discoveries,  systems,
techniques,  devices,  models,  prototypes,  copyrightable  works,  mask  works,  trademarks,  service  marks,  trade  dress,

Trecora  under  this  Agreement  that  relate  to  Trecora’s  business  and/or  the  business  of  affiliates  of  Trecora  using
Trecora’s  time,  data,  facilities  and/or  materials  (hereinafter  collectively  referred  to  as  the  “Intellectual  Property”)
belong to and shall remain the sole and exclusive property of Trecora forever. Carter hereby assigns to Trecora all of
Carter’s right, title, and interest to all such Intellectual Property.

Carter agrees, without additional compensation, to cooperate and do all lawful things requested by Trecora to protect
Trecora  ownership  rights  in  all  Intellectual  Property. After  termination  of  this Agreement,  Trecora  shall  compensate
Carter at a reasonable rate for the time actually spent by Carter in response to such requests. If Trecora is unable for any
reason to secure Carter’s signature on any document needed, Carter hereby irrevocably designates Trecora and its duly
authorized  officers  and  agents  as  Carter’s  agent  to  act  for  and  on  Carter’s  behalf  to  do  all  lawfully  permitted  acts  to
further the purposes of this paragraph with the same legal force and effect as if executed by Carter.

The  provisions  of  Section  9  shall  survive  any  termination  or  expiration  of  this  Agreement  (for  whatever  cause  or
reason).

10.     Confidential Information.

10.1 Definition of Confidential Information.  During Carter’s independent contractor relationship under this Agreement,
Trecora  shall  provide  to  Carter  confidential,  proprietary,  and  trade  secret  information  regarding  Trecora,  and/or
affiliates  of  Trecora,  that  Carter  has  not  previously  had  access  to  or  knowledge  of  before  the  execution  of  this
Agreement  including,  without  limitation,  Intellectual  Property,  technical  information,  business  and  marketing  plans,
strategies,  financing,  plans,  business  policies  and  practices  of  Trecora,  and/or  affiliates  of  Trecora,  know-how,
specialized training, mailing lists, client lists, potential client lists, pricing information, or other forms of information
considered by Trecora to be confidential, proprietary, or in the nature of trade secrets (hereafter collectively referred to
as  “Confidential  Information”)  that  Trecora  and  its  affiliates  desire  to  protect. In  exchange  for  Trecora’s  promises  to
provide  Carter  with  Confidential  Information,  Carter  shall  not  during  the  period  of  this  Agreement  or  at  any  time
thereafter, disclose to anyone, publish, or use for any purpose, any Confidential Information or Intellectual Property,
except  as  properly  required  in  the  ordinary  course  of  Trecora’s  business  or  as  directed  and  authorized  by  Trecora.
Confidential  Information  does  not  include  information  that  is  (i)  in  the  public  domain  or  becomes  part  of  the  public
domain through no fault of Carter or (ii) was known by Carter prior to Carter’s association with Trecora, as evidenced
by written records existing at that time.

10.2 Nonuse/Nondisclosure of Confidential Information. Carter shall use his best efforts and diligence both during and
after termination of this Agreement to protect the confidential, trade secret, or proprietary character of all Confidential
Information  and  shall  not,  directly  or  indirectly,  disclose  or  use  for  his  own  purposes  or  those  of  any  other  person,
company, business entity, or other organization whatsoever, and agrees to hold in strictest confidence any Confidential
Information relating to or belonging to Trecora or any information which has been given to Carter in confidence, except
when given express permission to do so by Trecora. Carter will not disclose Trecora’s Confidential Information to any
individual,  corporation,  partnership,  limited  liability  company,  association,  trust,  other  entity,  organization,  or  other
third party (other than in conjunction with the performance of his duties as a contractor of Trecora) without the prior
written  consent  of  Trecora  and  shall  not  use  or  attempt  to  use  any  such  information  in  any  manner  other  than  in
connection with his performance of Consulting Services for Trecora under this Agreement, unless required by law to
disclose such information, in which case Carter shall provide Trecora with written notice of such requirement as far in
advance  of  such  anticipated  disclosure  as  possible. Further,  Carter  agrees  that  any  disclosure  of  Confidential
Information is to persons who are aware of and agree that the Confidential Information must be kept confidential and
who agree in writing to abide by the provisions set forth in Section 10 of this Agreement.

10.3 Confidential Information of Third Parties.  Carter represents and warrants to Trecora that: (a) Carter is not bound
by  any  agreement,  whether  formal  or  informal,  verbal  or  written,  that  would  preclude  Carter  from  entering  into  this
Agreement with Trecora, (b) Carter will not use or disclose any confidential information, proprietary information, or
trade  secrets  of  any  previous  employer  or  other  third  party  in  the  performance  of  his  Consulting  Services  under  this
Agreement;  and  (c)  Carter  has  not  taken  and  will  not  take  any  confidential  information,  proprietary  information,  or
trade secrets of any previous employer or other third party for use in the performance of his Consulting Services under
this Agreement.

10.4    This Agreement does not supersede any prior or other confidentiality duties Carter owes to Trecora (whether
under written agreements, Trecora policies, applicable law, or any other means), but is in addition thereto, and any such
prior confidentiality duties continue unabated.

10.5    The provisions of Section 10 shall survive any termination or expiration of this Agreement (for whatever cause
or reason).

11.        LIMITATION  OF  LIABILITY.   NOTWITHSTANDING ANY  PROVISION  OF  THIS AGREEMENT  TO
THE  CONTRARY,  NEITHER  TRECORA,  NOR  CARTER  NOR  THEIR  RESPECTIVE  PARTNERS,  OWNERS,
OFFICERS,  MANAGERS,  GENERAL  PARTNERS, AGENTS,  EMPLOYEES,  CONTRACTORS,  SUBSIDIARIES
OR  AFFILIATES  (OR  THEIR  RESPECTIVE  PARTNERS,  OWNERS,  OFFICERS,  MANAGERS,  GENERAL
PARTNERS, AGENTS,  EMPLOYEES  OR  CONTRACTORS),  SHALL  BE  LIABLE  OR  RESPONSIBLE  TO  THE
OTHER  PARTY  OR  TO  ITS  PARTNERS,  OWNERS,  SUBSIDIARIES, AFFILIATES,  OFFICERS,  MANAGERS,
GENERAL  PARTNERS,  AGENTS,  EMPLOYEES,  CONTRACTORS  OR  TO  ANY  OF  THEIR  RESPECTIVE
INSURERS,  FOR  ANY  INCIDENTAL,  INDIRECT,  PUNITIVE,  SPECIAL  OR  CONSEQUENTIAL  DAMAGES
WHATSOEVER CONNECTED WITH OR RESULTING FROM PERFORMANCE OR NON-PERFORMANCE OF
THIS  AGREEMENT,  OR  ANYTHING  DONE  IN  CONNECTION  HEREWITH  (OTHER  THAN  PAYMENTS
EXPRESSLY  REQUIRED  AND  PROPERLY  DUE  UNDER  THIS  AGREEMENT),  IRRESPECTIVE  OF
WHETHER  SUCH  CLAIMS  OR  DAMAGES  ARE  BASED  UPON  BREACH  OF  WARRANTY,  BREACH  OF
DUTY (INCLUDING WITHOUT LIMITATION NEGLIGENCE, WHETHER OF COMPANY, CONSULTANT OR
OTHERS),  STRICT  LIABILITY,  CONTRACT,  OPERATION  OF  LAW  OR  OTHERWISE, AND  REGARDLESS
WHETHER  SUCH  PARTY  HAS  BEEN  ADVISED  OF  THE  POSSIBILITY  OF  SUCH  DAMAGES.  THE
FOREGOING  SHALL  EXPRESSLY  SURVIVE  THE  EXPIRATION  OR  EARLY  TERMINATION  OF  THIS
AGREEMENT.

12.     Insider Trading. Carter agrees that he is subject to Trecora’s Insider Trading Policy and other Trecora policies
and procedures relating to insider trading, including restrictions on trading outside of designated window periods. The
above  is  subject,  of  course,  to  the  general  prohibitions  on  trading  if  Carter  is  in  possession  of  material  non-public
information.

13.    Notice.  Any notice or communication permitted or required by this Agreement shall be deemed effective when
personally  delivered  or  deposited,  postage  prepaid,  in  the  first  class  mail  of  the  United  States  properly  or  sent  via
