Our Company

PART I

We are a growth‑oriented, Midland, Texas‑based oilfield services company providing hydraulic fracturing and other complementary
services to leading upstream oil and gas companies engaged in the exploration and production, or E&P, of North American unconventional
oil and natural gas resources. Our operations are primarily focused in the Permian Basin, where we have cultivated longstanding customer
relationships with some of the region’s most active and well‑capitalized E&P companies. The Permian Basin is widely regarded as the most
prolific oil‑producing area in the United States, and we believe we are one of the leading providers of hydraulic fracturing services in the
region by hydraulic horsepower, or HHP. During the year ended December 31, 2018, we purchased and deployed four newbuild hydraulic
fracturing units, bringing our total horse power to 905,000 HHP, or 20 deployed fleets.

On December 31, 2018, we consummated the purchase of certain pressure pumping assets and real property from Pioneer Natural

Resources USA, Inc. (“Pioneer”) and Pioneer Natural Resources Pumping Services, LLC (“Pioneer Pumping Services”). Prior to the
purchase, the pressure pumping assets exclusively provided integrated pressure pumping services to Pioneer’s completion and production
operations. The acquisition cost of the assets was comprised of $110.0 million of cash and 16.6 million shares of our common stock. In
connection with the consummation of transaction, we became a strategic long-term service provider to Pioneer, providing pressure
pumping and related services for a term of up to 10 years.

The pressure pumping assets acquired include eight hydraulic fracturing fleets with a total of 510,000 HHP, four coiled tubing units and

an associated equipment maintenance facility. Through this acquisition, we expanded our existing presence in the Permian Basin, and
increased our pumping capacity by 56%, to 28 hydraulic fracturing fleets with a total of 1,415,000 HHP, further strengthening our position
as one of the largest pure-play provider of integrated well completion services in the Permian Basin.

Our modern hydraulic fracturing fleet has been designed to handle the most challenging Permian Basin operating conditions and the

region’s increasingly high‑intensity well completions, which are characterized by longer horizontal wellbores, more frac stages per lateral
and increasing amounts of proppant per well.

In addition to our core hydraulic fracturing operations, we also offer a suite of complementary well completion and production
services, including cementing, coiled tubing, flowback services and drilling. We believe these complementary services create operational
efficiencies for our customers and allow us to capture a greater portion of their capital spending across the lifecycle of an unconventional
well.

Our primary business objective is to serve as a strategic long-term partner to our customers. We achieve this objective by providing

reliable, high‑quality services that are tailored to our customers’ needs and synchronized with their well development programs. This
alignment assists our customers in optimizing the long‑term development of their unconventional resources. Over the past three years, we
have leveraged our strong relationships in the Permian Basin to significantly grow our installed HHP capacity and organically build our
cementing and coiled tubing lines of business. Consistent with past performance, we believe our substantial market presence will continue
to yield a variety of actionable growth opportunities allowing us to expand both our hydraulic fracturing and complementary services going
forward. To this end, we intend to continue to differentiate ourselves, consistent with our past practice, by opportunistically deploying new
equipment on a long‑term dedicated basis.

Our Services

We conduct our business through five operating segments: hydraulic fracturing (inclusive of acidizing), cementing, coil tubing,
flowback and drilling. For reporting purposes, the hydraulic fracturing and cementing operating segments are aggregated into our one
reportable segment: pressure pumping. For additional financial information on our reportable segment, please see Part II - Item 8. Financial
Statements and Supplementary Data.

Pressure Pumping

Hydraulic Fracturing

We primarily provide hydraulic fracturing services to E&P companies in the Permian Basin. These services are intended to optimize
hydrocarbon flow paths during the completion phase of horizontal shale wellbores. We have significant expertise in multi‑stage fracturing
of horizontal oil‑producing wells in unconventional geological formations. During the year ended December 31, 2018, we continued to
organically grow our hydraulic fracturing business to a total of 20 hydraulic fracturing fleets with an aggregate of 905,000 HHP. Following
the consummation of our acquisition of pressure pumping assets from Pioneer Pressure Pumping Services, we increased our hydraulic
fracturing business to a total 28 fleets, or 1,415,000 HHP.

The fracturing process consists of pumping a fracturing fluid into a well at sufficient pressure to fracture the formation. Materials
known as proppants, which in our business are comprised primarily of sand, are suspended in the fracturing fluid and are pumped into the
fracture to prop it open. The fracturing fluid is designed to “break,” or loosen viscosity, and be forced out of the formation by its pressure,
leaving the proppants suspended in the fractures created, thereby increasing the mobility of the hydrocarbons. As a result of the fracturing
process, production rates are usually enhanced substantially, thus increasing the rate of return of hydrocarbons for the operator.

We own and operate a fleet of mobile hydraulic fracturing units and other auxiliary equipment to perform fracturing services. We also

refer to all of our fracturing units, other equipment and vehicles necessary to perform a fracturing job as a “fleet” and the personnel
assigned to each fleet as a “crew.” Each hydraulic fracturing unit consist primarily of a high pressure hydraulic pump, diesel engine,
transmission and various hoses, valves, tanks and other supporting equipment that are typically mounted to a flatbed trailer.

We provide dedicated equipment, personnel and services that are tailored to meet each of our customer’s needs. Each fleet has a
designated team of personnel, which allows us to provide responsive and customized services, such as project design, proppant and other
consumables procurement, real‑time data provision and post‑completion analysis for each of our jobs. Many of our hydraulic fracturing
fleets and associated personnel have continuously worked with the same customer for the past several years promoting deep relationships
and a high degree of coordination and visibility into future customer activity levels. Furthermore, in light of our substantial market presence
and historically high fleet utilization levels, we have established a variety of entrenched relationships with key equipment, sand and other
downhole consumable suppliers, including over 30 sand suppliers utilized in 2018. These strategic relationships ensure ready access to
equipment, parts and materials on a timely and economic basis and allow our dedicated procurement logistics team to ensure consistently
safe and reliable operations.

Cementing

We provide cementing services for completion of new wells and remedial work on existing wells. Cementing services use pressure

pumping equipment to deliver a slurry of liquid cement that is pumped down a well between the casing and the borehole. Cementing
provides isolation between fluid zones behind the casing to minimize potential damage to hydrocarbon bearing formations or the integrity
of freshwater aquifers, and provides structural integrity for the casing by securing it to the earth. Cementing is also done when
recompleting wells, where one zone is plugged and another is opened.

As of December 31, 2018, we operated a total of 20 cementing units, with 13 units operating in the Permian Basin and 7 units operating

in the Uinta‑Piceance Basin. We believe that our cementing segment provides an organic growth opportunity for us to expand our service
offerings within our existing customer base.

Other Services

Coiled Tubing

Coiled tubing services involve injecting coiled tubing into wells to perform various completion well intervention operations. Coiled
tubing is a flexible steel pipe with a diameter of typically less than three inches and manufactured in continuous lengths of thousands of
feet. It is wound or coiled on a truck‑mounted reel for onshore applications. Due to its small diameter, coiled tubing can be inserted into
existing production tubing and used to perform a variety of services to enhance the flow of oil or natural gas.

The principal advantages of using coiled tubing include the ability to (i) continue production from the well without interruption, thus
reducing the risk of formation damage, (ii) move continuous coiled tubing in and out of a well significantly faster than conventional pipe
used with a workover rig, which must be jointed and unjointed, (iii) direct fluids into a wellbore with more precision, allowing for improved
stimulation fluid placement, (iv) provide a source of energy to power a downhole motor or manipulate down‑hole tools and (v) enhance
access to remote fields due to the smaller size and mobility.

As of December 31, 2018, we had 8 coiled tubing units of various sizes. We believe these units are well suited for the performance

requirements of the unconventional resource markets we serve.

Flowback Services

Our flowback services consist of production testing, solids control, hydrostatic testing and torque services. Flowback involves the
process of allowing fluids to flow from the well following a treatment, either in preparation for an impending phase of treatment or to return
the well to production. Our flowback equipment consists of manifolds, accumulators, valves, flare stacks and other associated equipment
that combine to form up to a total of five well‑testing spreads. We provide flowback services in the Permian Basin and mid‑continent
markets.

Surface Air Drilling

We operated a surface air drilling operation in the Uinta‑Piceance Basin, which offered pre‑set surface air drilling services to target
depths of approximately 4,000 feet in areas of fragile geology. Air drilling is a technique in which oil, natural gas, or geothermal wells are
drilled by creating a pressure within the well that is lower than the reservoir pressure, which results in increased rates of penetration,
reduced formation damage and reduced drilling costs.

On August 31, 2018, we divested our surface air drilling operations, included in our "all other" operating segment category in our
financial statements, in order to continue to position ourselves as a Permian Basin-focused pressure pumping business because we believe
the pressure pumping market in the Permian Basin offers more supportive long-term growth fundamentals. The divestiture of our surface
air drilling operations did not qualify for presentation and disclosure as discontinued operations, and accordingly we have recorded the
resulting loss on disposal of our surface air drilling of $0.3 million, as part of our loss on disposal of asset in our statement of operations
included in this annual report. The divestiture of our surface air drilling operations resulted in a reduction in the number of our current
operating segments. The change in the number of our operating segments did not impact our reportable segment information reported in the
financial statements included in this annual report.

Competitive Strengths

Our primary business objective is to serve as a strategic long-term partner for our customers. We achieve this objective by providing

reliable, high‑quality services that are tailored to our customers’ needs and synchronized with their well development programs. This
alignment assists our customers in optimizing the long‑term development of their unconventional resources. We believe that the following
competitive strengths differentiate us from our peers and uniquely position us to achieve our primary business objective.

4

•

Strong market position in the Permian Basin. We believe we are one of the largest hydraulic fracturing provider by HHP in the
Permian Basin, which is the most prolific oil producing area in the United States. Our longstanding customer relationships and
substantial Permian Basin market presence uniquely position us to continue growing in tandem with the basin’s ongoing
development. The Permian Basin is a mature, liquids‑rich basin with well known geology and a large, exploitable resource base
that delivers attractive E&P producer economics at or below current commodity prices. As a result of its significant size, coupled
with the presence of multiple prospective geologic benches and other favorable characteristics, the Permian Basin has become
widely recognized as the most attractive and economic oil resource in North America.

Our operational focus has historically been in the Permian Basin’s Midland sub‑basin in support of our customers’ core operations.
More recently, however, many of our customers have made sizeable acquisitions in the Delaware Basin, and we have expanded our
services into the Delaware Basin to help develop their acreage. Further, we believe that we are uniquely positioned to capture a
large addressable growth opportunity as the basin develops. For the foreseeable future, we expect both the Midland Basin and the
Delaware Basin to continue to command a disproportionate share of future North American E&P spending.

• Hydraulic fracturing is highly levered to increasing drilling activity and completion intensity levels. The combination of an
expanding Permian Basin horizontal rig count and more complex well completions has a compounding effect on HHP demand
growth. Horizontal drilling has become the default method for E&P operators to most economically extract unconventional
resources, and the number of horizontal rigs has increased from 22% of the total Permian Basin rig count in December 2011 to
approximately 91% of the Permian Basin rig count at December 31, 2018. As the horizontal rig count has grown, well completion
intensity levels have also increased as a result of longer wellbore lateral lengths, more fracturing stages per foot of lateral and
increasing amounts of proppant per stage. Furthermore, the ongoing improvement in drilling and completion efficiencies, driven
by innovations such as multi‑well pads and zipper fracs, have further increased the demand for HHP. Taken together, these
demand drivers have helped contribute to the full utilization of our fleet and have us well positioned to capture future growth
opportunities and enhanced pricing for our services.

•

•

•

Deep relationships and operational alignment with high‑quality, Permian Basin‑focused customers.  Our deep local roots,
operational expertise and commitment to safe and reliable service have allowed us to cultivate longstanding customer relationships
with the most active and well‑capitalized Permian Basin operators. Many of our current customers have worked with us since our
inception and have integrated our fleet scheduling with their well development programs. This high degree of operational
alignment and their continued support have allowed us to maintain relatively high utilization rates over time. As our customers
increase activity levels, we expect to continue to leverage these strong relationships to keep our fleet fully utilized and selectively
expand our platform in response to specific customer demand.

Standardized fleet of modern, well‑maintained equipment. We have a large, homogenous fleet of modern equipment that is
configured to handle the Permian Basin’s most complex, highest‑intensity, hydraulic fracturing jobs. We believe that our fleet
design is a key advantage compared to many of our competitors who have fracturing units that are not optimized for Permian
Basin conditions. Our fleet is largely standardized across units to facilitate efficient maintenance and repair, reducing equipment
downtime and improving labor efficiency. Furthermore, our strong relationships with a variety of key suppliers and vendors
provide us with the reliable access to the equipment necessary to support our continued organic growth strategy.

Proven cross‑cycle financial performance. Over the past several years, we have maintained high cross‑cycle fleet utilization
rates. Since September 2016 our fleet has consistently recorded a utilization rate of approximately 100%. Our consistent track
record of steady growth, coupled with our ability to quickly deploy new HHP on a dedicated and fully utilized basis, has resulted
in revenue growth across the industry’s cycles. We believe that we will be able to continue to grow faster than our competitors
while preserving attractive EBITDA margins as a result of our differentiated service offerings and a robust backlog of demand for
our services. Furthermore, we believe that our philosophy of maintaining modest

5

financial leverage and a healthy balance sheet has left us more conservatively capitalized than our peers. We expect that improving
market fundamentals, our superior execution and our customer‑focused approach should result in strong financial performance.

•

Seasoned management and operating team. We have a seasoned executive management team, with our senior members
contributing more than 100 years of collective industry and financial experience. Members of our management team founded our
business and seeded our company with a portion of our original investment capital. We believe their track record of successfully
building premier oilfield service companies in the Permian Basin, as well as their deep roots and relationships throughout the West
Texas community, provide a meaningful competitive advantage for our business. In addition, our management team has
assembled a loyal group of highly‑motivated and talented managers and field personnel, and we have had minimal manager‑level
turnover in our core service divisions over the past three years. We employ a balanced decision‑making structure that empowers
managerial and field personnel to work directly with customers to develop solutions while leveraging senior management’s
oversight. This collaborative approach fosters strong customer links at all levels of the organization and effectively
institutionalizes customer relationships beyond the executive suite.

Strategy

Our strategy is to:

•

•

•

Capture an increasing share of rising demand for hydraulic fracturing services in the Permian Basin.  We intend to continue to
position ourselves as a Permian Basin‑focused hydraulic fracturing business, as we believe the Permian Basin hydraulic fracturing
market offers supportive long‑term growth fundamentals. These fundamentals are characterized by increased demand for our
HHP, driven by increasing drilling activity and well completion intensity levels. We are currently operating at approximately
100% utilization, and we believe we are strategically positioned to deploy additional hydraulic fracturing equipment as our
customers continue to develop their assets in the Midland Basin and Delaware Basin.

Capitalize on improving efficiency gains. We intend to continue to work with our customers and vendors to improve our
operational efficiencies and enhance our margins. We believe that improving our efficiencies will result in greater revenue and
enhanced margins as fixed costs are spread over a broader revenue base.

Cross‑sell our complementary services. In addition to our hydraulic fracturing services, we offer a broad range of complementary
services in support of our customers’ development activities, including cementing, coiled tubing, flowback services and drilling.
These complementary services create operational efficiencies for our customers, and allow us to capture a greater percentage of
their capital spending across the lifecycle of an unconventional well. We believe that, as our customers increase spending levels,
we are well positioned to continue cross‑selling and growing our complementary service offerings.

• Maintain financial stability and flexibility to pursue growth opportunities.  Consistent with our historical practices, we plan to
continue to maintain a conservative balance sheet, which will allow us to better react to potential changes in industry and market
conditions and opportunistically grow our business. In the near term, we intend to continue our past practice of aligning our
growth capital expenditures with visible customer demand by strategically deploying new equipment on a long‑term, dedicated
basis in response to inbound customer requests. We will also selectively evaluate potential strategic acquisitions that increase our
scale and capabilities or diversify our operations.

Our Customers

Our customers consist primarily of oil and natural gas producers in North America. Our top five customers accounted for

approximately 68.7%, 66.0% and 58.0% of our revenue, for the years ended December 31, 2018, 2017 and 2016, respectively. For the year
ended December 31, 2018, XTO Energy, Parsley Energy Operations, LLC and

6

CrownQuest Operating, LLC, accounted for 24.1%, 16.5%, and 12.2%, respectively, of total revenue. No other customer accounted for
more than 10% of total revenue for the year ended December 31, 2018.

Competition

The markets in which we operate are highly competitive. To be successful, an oilfield services company must provide services that

meet the specific needs of oil and natural gas exploration and production companies at competitive prices. Competitive factors impacting
sales of our services are price, reputation, technical expertise, service and equipment quality, and health and safety standards. Although we
believe our customers consider all of these factors, we believe price is a key factor in E&P companies’ criteria in choosing a service
provider. While we seek to price our services competitively, we believe many of our customers elect to work with us based on our deep
local roots, operational expertise, equipment’s ability to handle the most complex Permian Basin well completions, and commitment to
safety and reliability.

We provide our services primarily in the Permian Basin, and we compete against different companies in each service and product line

we offer. Our competition includes many large and small oilfield service companies, including the largest integrated oilfield services
companies. Our major competitors for hydraulic fracturing services include C&J Energy Services, Halliburton, Patterson‑UTI Energy Inc.,
RPC, Inc., Schlumberger, Keane Group, Inc., Liberty Oilfield Services, FTS International, Inc., Superior Energy Services and a number of
locally oriented businesses.

Seasonality

Our results of operations have historically reflected seasonal tendencies, generally in the fourth quarter, relating to the conclusion of
our customers’ annual capital expenditure budgets, the holidays and inclement winter weather during which we may experience declines in
our operating results.

Operating Risks and Insurance

Our operations are subject to hazards inherent in the oilfield services industry, such as accidents, blowouts, explosions, fires and spills

and releases that can cause personal injury or loss of life, damage or destruction of property, equipment, natural resources and the
environment and suspension of operations.

In addition, claims for loss of oil and natural gas production and damage to formations can occur in the oilfield services industry. If a

serious accident were to occur at a location where our equipment and services are being used, it could result in us being named as a
defendant in lawsuits asserting large claims.

Our business involves the transportation of heavy equipment and materials, and as a result, we may also experience traffic accidents

which may result in spills, property damage and personal injury.

Despite our efforts to maintain safety standards, we from time to time have suffered accidents in the past and anticipate that we could
experience accidents in the future. In addition to the property damage, personal injury and other losses from these accidents, the frequency
and severity of these incidents affect our operating costs and insurability and our relationships with customers, employees, regulatory
agencies and other parties. Any significant increase in the frequency or severity of these incidents, or the general level of compensation
awards, could adversely affect the cost of, or our ability to obtain, workers’ compensation and other forms of insurance, and could have
other material adverse effects on our financial condition and results of operations.

We maintain commercial general liability, workers’ compensation, business auto, commercial property, umbrella liability, excess
liability, and directors and officers insurance policies providing coverages of risks and amounts that we believe to be customary in our
industry. Further, we have pollution legal liability coverage for our business entities, which would cover, among other things, third party
liability and costs of clean up relating to environmental contamination on our premises while our equipment is in transit and on our
customers’ job site. With respect to our hydraulic fracturing operations, coverage would be available under our pollution legal liability
policy

7

for any surface or subsurface environmental clean‑up and liability to third parties arising from any surface or subsurface contamination. We
also have certain specific coverages for some of our businesses, including our hydraulic fracturing services.

Although we maintain insurance coverage of types and amounts that we believe to be customary in the industry, we are not fully
insured against all risks, either because insurance is not available or because of the high premium costs relative to perceived risk. Further,
insurance rates have in the past been subject to wide fluctuation and changes in coverage could result in less coverage, increases in cost or
higher deductibles and retentions. Liabilities for which we are not insured, or which exceed the policy limits of our applicable insurance,
could have a material adverse effect on us. See “Risk Factors” for a description of certain risks associated with our insurance policies.

Environmental and Occupational Health and Safety Regulations

Our operations are subject to stringent laws and regulations governing the discharge of materials into the environment or otherwise
relating to environmental protection, and occupational health and safety. Numerous federal, state and local governmental agencies issue
regulations that often require difficult and costly compliance measures that could carry substantial administrative, civil and criminal
penalties and may result in injunctive obligations for non compliance. These laws and regulations may, for example, restrict the types,
quantities and concentrations of various substances that can be released into the environment, limit or prohibit construction or drilling
activities on certain lands lying within wilderness, wetlands, ecologically or seismically sensitive areas and other protected areas, or require
action to prevent or remediate pollution from current or former operations. Moreover, it is not uncommon for neighboring landowners and
other third parties to file claims for personal injury and property damage allegedly caused by the release of hazardous substances,
hydrocarbons or other waste products into the environment. Changes in environmental, health and safety laws and regulations occur
frequently, and any changes that result in more stringent and costly requirements could materially adversely affect our operations and
financial position. We have not experienced any material adverse effect from compliance with these requirements, however, this trend may
not continue in the future.

Below is an overview of some of the more significant environmental, health and safety requirements with which we must comply. Our

customers’ operations are subject to similar laws and regulations. Any material adverse effect of these laws and regulations on our
customers’ operations and financial position may also have an indirect material adverse effect on our operations and financial position.

Waste Handling. We handle, transport, store and dispose of wastes that are subject to the Resource Conservation and Recovery Act

(“RCRA”) and comparable state laws and regulations, which affect our activities by imposing requirements regarding the generation,
transportation, treatment, storage, disposal and cleanup of hazardous and non hazardous wastes. With federal approval, the individual states
administer some or all of the provisions of RCRA, sometimes in conjunction with their own, more stringent requirements. Although certain
petroleum production wastes are exempt from regulation as hazardous wastes under RCRA, such wastes may constitute “solid wastes” that
are subject to the less stringent requirements of non hazardous waste provisions.

Administrative, civil and criminal penalties can be imposed for failure to comply with waste handling requirements. Moreover, the
EPA or state or local governments may adopt more stringent requirements for the handling of non hazardous wastes or recategorize some
non hazardous wastes as hazardous for future regulation. Indeed, legislation has been proposed from time to time in Congress to
recategorize certain oil and natural gas exploration, development and production wastes as hazardous wastes. Several environmental
organizations have also petitioned the EPA to modify existing regulations to recategorize certain oil and natural gas exploration,
development and production wastes as hazardous. Any such changes in these laws and regulations could have a material adverse effect on
our capital expenditures and operating expenses. Although we do not believe the current costs of managing our wastes, as presently
classified, to be significant, any legislative or regulatory reclassification of oil and natural gas exploration and production wastes could
increase our costs to manage and dispose of such wastes.

Remediation of Hazardous Substances. The Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”
or “Superfund”) and analogous state laws generally impose liability without regard to fault or legality of the original conduct, on classes of
persons who are considered to be responsible for the release of a hazardous substance into the environment. These persons include the
current owner or operator of a contaminated facility, a former owner or operator of the facility at the time of contamination and those
persons that disposed or arranged for the disposal of the hazardous substance at the facility. Liability for the costs of removing or
remediating previously disposed wastes or contamination, damages to natural resources, the costs of conducting certain health studies,
amongst other things, is strict and joint and several. In addition, it is not uncommon for neighboring landowners and other third parties to
file claims for personal injury and property damage allegedly caused by the hazardous substances released into the environment. In the
course of our operations, we use materials that, if released, would be subject to CERCLA and comparable state laws. Therefore,
governmental agencies or third parties may seek to hold us responsible under CERCLA and comparable state statutes for all or part of the
costs to clean up sites at which such hazardous substances have been released.

One of our facilities in Midland, Texas is located within the boundaries of the West County Road 112 federal Superfund site, which
site and the associated investigation and cleanup is being managed by EPA Region 6. The site’s soil and groundwater is contaminated with
chromium and hexavalent chromium as a result of historic site operations unaffiliated with the Company and unassociated with the
Company’s operations. Toxic tort claims also have been asserted as a result of this groundwater contamination against various unaffiliated
parties. In 2013, in order to reduce the Company’s risk of incurring any future liabilities in connection with this site, the Company
negotiated and obtained a bona fide prospective purchaser (“BFPP”) letter from EPA Region 6 in connection with a reorganization of the
facility site ownership and lease. The BFPP letter generally acknowledges and provides that the Company is unaffiliated with any
potentially responsible parties or known contamination that is the subject of the Superfund action, the Company agrees to comply with any
future land use restrictions that may be imposed in connection with a site remedy (none have been imposed to date), and the Company
agrees to cooperate with and provide access and assistance to EPA Region 6 in connection with the remediation. In exchange for these
undertakings, the Company will not be subject to any CERCLA action by the EPA. In addition, the Company separately obtained a 10‑year
environmental pollution legal liability insurance policy, effective March 4, 2013, with an aggregate limit of $20 million to insure against
potential third‑party claims and any known or unknown pre‑existing conditions at the site, including Superfund or toxic tort liabilities. Both
prior to and since obtaining the BFPP letter and the insurance policy, no claims have been made or threatened against the Company or any
of its affiliated persons or entities with regard to this Superfund site or any related liabilities, and the Company has not incurred any
significant expenses in connection with this matter.

NORM. In the course of our operations, some of our equipment may be exposed to naturally occurring radioactive materials
(“NORM”) associated with oil and gas deposits and, accordingly may result in the generation of wastes and other materials containing
NORM. NORM exhibiting levels of radiation in excess of established state standards are subject to special handling and disposal
requirements, and any storage vessels, piping and work area affected by NORM may be subject to remediation or restoration requirements.

Water Discharges. The Clean Water Act, Safe Drinking Water Act, Oil Pollution Act and analogous state laws and regulations impose

restrictions and strict controls regarding the unauthorized discharge of pollutants, including produced waters and other gas and oil wastes,
into regulated waters. The discharge of pollutants into regulated waters is prohibited, except in accordance with the terms of a permit issued
by the EPA or the state. Also, spill prevention, control and countermeasure plan requirements require appropriate containment berms and
similar structures to help prevent the contamination of regulated waters.

Air Emissions. The Clean Air Act (“CAA”) and comparable state laws and regulations, regulate emissions of various air pollutants

through the issuance of permits and the imposition of other emissions control requirements. The EPA has developed, and continues to
develop, stringent regulations governing emissions of air pollutants from specified sources. New facilities may be required to obtain permits
before work can begin, and existing facilities may be required to obtain additional permits and incur capital costs in order to remain in
compliance. These and other laws and regulations may increase the costs of compliance for some facilities where we operate. Obtaining or
renewing permits also has the potential to delay the development of oil and natural gas projects.

9

Climate Change. The EPA has determined that greenhouse gases (“GHGs”) present an endangerment to public health and the

environment because such gases contribute to warming of the earth’s atmosphere and other climatic changes. Based on these findings, the
EPA has adopted and implemented, and continues to adopt and implement, regulations that restrict emissions of GHGs under existing
provisions of the CAA. The EPA also requires the annual reporting of GHG emissions from certain large sources of GHG emissions in the
United States, including certain oil and gas production facilities. The U.S. Congress has from time to time considered adopting legislation
to reduce emissions of GHGs and almost one‑half of the states have already taken legal measures to reduce emissions of GHGs primarily
through the planned development of GHG emission inventories and/or regional GHG cap and trade programs. In December 2015, the
United States joined the international community at the 21st Conference of the Parties of the United Nations Framework Convention on
Climate Change in Paris, France. The resulting Paris Agreement calls for the parties to undertake “ambitious efforts” to limit the average
global temperature, and to conserve and enhance sinks and reservoirs of greenhouse gases. The Paris Agreement entered into force in
November 2016. On June 1, 2017, President Trump announced that the United States planned to withdraw from the Paris Agreement and to
seek negotiations either to reenter the Paris Agreement on different terms or establish a new framework agreement. The Paris Agreement
provides for a four‑year exit process beginning when it took effect in November 2016, which would result in an effective exit date of
November 2020. The United States’ adherence to the exit process is uncertain and/or the terms on which the United States may reenter the
Paris Agreement or a separately negotiated agreement are unclear at this time.

Moreover, climate change may cause more extreme weather conditions and increased volatility in seasonal temperatures. Extreme
weather conditions can interfere with our operations and increase our costs, and damage resulting from extreme weather may not be fully
insured.

Endangered and Threatened Species.  Environmental laws such as the Endangered Species Act (“ESA”) and analogous state laws may

impact exploration, development and production activities in areas where we operate. The ESA provides broad protection for species of
fish, wildlife and plants that are listed as threatened or endangered. Similar protections are offered to migratory birds under the Migratory
Bird Treaty Act and various state analogs. The U.S. Fish and Wildlife Service may identify previously unidentified endangered or
threatened species or may designate critical habitat and suitable habitat areas that it believes are necessary for survival of a threatened or
endangered species, which could cause us or our customers to incur additional costs or become subject to operating restrictions or operating
bans in the affected areas.

Regulation of Hydraulic Fracturing and Related Activities. Our hydraulic fracturing operations are a significant component of our

business. Hydraulic fracturing is an important and common practice that is used to stimulate production of hydrocarbons, particularly
natural gas, from tight formations, including shales. The process, which involves the injection of water, sand and chemicals under pressure
into formations to fracture the surrounding rock and stimulate production, is typically regulated by state oil and natural gas commissions.
However, federal agencies have asserted regulatory authority over certain aspects of the process. For example, in May 2014, the EPA
issued an Advanced Notice of Proposed Rulemaking seeking comment on the development of regulations under the Toxic Substances
Control Act to require companies to disclose information regarding the chemicals used in hydraulic fracturing. Beginning in August 2012,
the EPA issued a series of rules under the CAA that establish new emission control requirements for certain oil and natural gas production
and natural gas processing operations and associated equipment. After several attempts to delay implementation, in September 2018 the
EPA issued a proposal to amend and reduce such requirements. In March 2015, the Bureau of Land Management (“BLM”) finalized a rule
governing hydraulic fracturing on federal lands. In June 2016, a federal district court judge in Wyoming struck down the final rule, finding
that the BLM lacked congressional authority to promulgate the rule. However, in July 2017, the BLM initiated a rulemaking to rescind the
final rule and reinstate the regulations that existed immediately before the published effective date of the rule. In light of the BLM’s
proposed rulemaking, in September 2017, the U.S. Court of Appeals for the Tenth Circuit dismissed the appeal and remanded with
directions to vacate the lower court’s opinion, leaving the final rule in place. The BLM initiated a rulemaking to rescind the final rule in
December 2017. Further, legislation to amend the Safe Drinking Water Act to repeal the exemption for hydraulic fracturing (except when
diesel fuels are used) from the definition of “underground injection” and require federal permitting and regulatory control of hydraulic
fracturing, as well as legislative proposals to require disclosure of the chemical constituents of the fluids used in the fracturing process,
have been proposed in recent sessions of Congress. Several

10

states and local jurisdictions in which we or our customers operate also have adopted or are considering adopting regulations that could
restrict or prohibit hydraulic fracturing in certain circumstances, impose more stringent operating standards and/or require the disclosure of
the composition of hydraulic fracturing fluids.

More recently, federal and state governments have begun investigating whether the disposal of produced water into underground
injection wells has caused increased seismic activity in certain areas. In March 2016, the United States Geological Survey identified six
states with the most significant hazards from induced seismicity, including Oklahoma, Kansas, Texas, Colorado, New Mexico and
Arkansas. The United States Geological Survey also noted the potential for induced seismicity in Ohio and Alabama. In response to
concerns regarding induced seismicity, regulators in some states have imposed, or are considering imposing, additional requirements in the
permitting of produced water disposal wells or otherwise to assess any relationship between seismicity and the use of such wells. For
example, Oklahoma issued new rules for wastewater disposal wells in 2014 that imposed certain permitting and operating restrictions and
reporting requirements on disposal wells in proximity to faults and also, from time to time, has developed and implemented plans directing
certain wells where seismic incidents have occurred to restrict or suspend disposal well operations. In particular, the Oklahoma Corporation
Commission released well completion seismicity guidelines in December 2016 for operators in the SCOOP and STACK that call for
hydraulic fracturing operations to be suspended following earthquakes of certain magnitudes in the vicinity. In addition, in February 2017,
the Oklahoma Corporation Commission’s Oil and Gas Conservation Division issued an order limiting future increases in the volume of oil
and natural gas wastewater injected into the ground in an effort to reduce the number of earthquakes in the state. The Texas Railroad
Commission adopted similar rules in 2014. In addition, in December 2016, the EPA released its final report regarding the potential impacts
of hydraulic fracturing on drinking water resources, concluding that “water cycle” activities associated with hydraulic fracturing may
impact drinking water resources under certain circumstances such as water withdrawals for fracturing in times or areas of low water
availability, surface spills during the management of fracturing fluids, chemicals or produced water, injection of fracturing fluids into wells
with inadequate mechanical integrity, injection of fracturing fluids directly into groundwater resources, discharge of inadequately treated
fracturing wastewater to surface waters, and disposal or storage of fracturing wastewater in unlined pits. The results of these studies could
lead federal and state governments and agencies to develop and implement additional regulations.

Increased regulation of hydraulic fracturing and related activities (whether as a result of the EPA study results or resulting from other

factors) could subject us and our customers to additional permitting and financial assurance requirements, more stringent construction
specifications, increased monitoring, reporting and record keeping obligations, and plugging and abandonment requirements. New
requirements could result in increased operational costs for us and our customers, and reduce the demand for our services.

OSHA Matters. The Occupational Safety and Health Act (“OSHA”) and comparable state statutes regulate the protection of the health

and safety of workers. In addition, the OSHA hazard communication standard requires that information be maintained about hazardous
materials used or produced in operations and that this information be provided to employees, state and local government authorities and the
public.

Employees

As of December 31, 2018, we employed 1,579 people. None of our employees are represented by labor unions or subject to collective

bargaining agreements.

Item 1A.    Risk Factors.

The following is a description of significant factors that could cause actual results to differ materially from those contained in forward-
looking statement made in this Annual Report on Form 10-K and presented elsewhere by management from time to time. Such factors may
have a material adverse effect on our business, financial condition and results of operations. It is not possible to predict or identify all such
factors. Consequently, you should not consider any such list to be a complete statement of all our potential risks or uncertainties. Due to
these, and other factors, past performance should not be considered an indication of future performance.

Our business and financial performance depends on the oil and natural gas industry and particularly on the level of capital spending
and exploration and production activity within the United States and in the Permian Basin, and a decline in prices for oil and natural
gas may have an adverse effect on our revenue, cash flows, profitability and growth.

Demand for most of our services depends substantially on the level of capital expenditures in the Permian Basin by companies in the

oil and natural gas industry. As a result, our operations are dependent on the levels of capital spending and activity in oil and gas
exploration, development and production. A prolonged reduction in oil and gas prices would generally depress the level of oil and natural
gas exploration, development, production, and well completion activity and would result in a corresponding decline in the demand for the
hydraulic fracturing services that we provide. The significant decline in oil and natural gas prices during 2015 and 2016 caused a reduction
in our customers’ spending and associated drilling and completion activities, which had an adverse effect on our revenue. If prices were to
decline, similar declines in our customers’ spending would have an adverse effect on our revenue. In addition, a worsening of these
conditions may result in a material adverse impact on certain of our customers’ liquidity and financial position resulting in further spending
reductions, delays in the collection of amounts owing to us and similar impacts.

Many factors over which we have no control affect the supply of, and demand for, and our customers’ willingness to explore, develop

and produce oil and natural gas, and therefore, influence prices for our services, including:

•

•

•

•

•

•

•

•

•

•

•

•

•

the domestic and foreign supply of, and demand for, oil and natural
gas;

the level of prices, and expectations about future prices, of oil and natural
gas;

the level of global oil and natural gas exploration and
production;

the cost of exploring for, developing, producing and delivering oil and natural
gas;

the supply of and demand for drilling and hydraulic fracturing
equipment;

the expected decline rates of current
production;

the price and quantity of foreign
imports;

political and economic conditions in oil and natural gas producing countries and regions, including the United States, the Middle
East, Africa, South America and Russia;

actions by the members of Organization of Petroleum Exporting Countries with respect to oil production levels and
announcements of potential changes in such levels;

speculative trading in crude oil and natural gas derivative
contracts;

the level of consumer product
demand;

the discovery rates of new oil and natural gas
reserves;

contractions in the credit
market;

13

•

•

•

•

•

•

•

•

the strength or weakness of the U.S.
dollar;

available pipeline and other transportation
capacity;

the levels of oil and natural gas
storage;

weather conditions and other natural
disasters;

domestic and foreign tax
policy;

domestic and foreign governmental approvals and regulatory requirements and
conditions;

the continued threat of terrorism and the impact of military and other action, including military action in the Middle
East;

technical advances affecting energy
consumption;

the proximity and capacity of oil and natural gas pipelines and other transportation
facilities;

the price and availability of alternative
fuels;

the ability of oil and natural gas producers to raise equity capital and debt
financing;

• merger and divestiture activity among oil and natural gas producers;

and

•

overall domestic and global economic
conditions.

These factors and the volatility of the energy markets make it extremely difficult to predict future oil and natural gas price movements

with any certainty. Such a decline would have a material adverse effect on our business, results of operation and financial condition.

The cyclical nature of the oil and natural gas industry may cause our operating results to fluctuate.

We derive our revenues from companies in the oil and natural gas exploration and production industry, a historically cyclical industry

with levels of activity that are significantly affected by the levels and volatility of oil and natural gas prices. We have experienced, and may
in the future experience, significant fluctuations in operating results as a result of the reactions of our customers to changes in oil and
natural gas prices. For example, prolonged low commodity prices experienced by the oil and natural gas industry during 2015 and 2016,
combined with adverse changes in the capital and credit markets, caused many exploration and production companies to reduce their capital
budgets and drilling activity. This resulted in a significant decline in demand for oilfield services and adversely impacted the prices oilfield
services companies could charge for their services. In addition, a majority of the service revenue we earn is based upon a charge for a
relatively short period of time (for example, a day, a week or a month) for the actual period of time the service is provided to our
customers. By contracting services on a short‑term basis, we are exposed to the risks of a rapid reduction in market prices and utilization
and resulting volatility in our revenues.

The majority of our operations are located in the Permian Basin, making us vulnerable to risks associated with operating in one major
geographic area.

Our operations are geographically concentrated in the Permian Basin. For the years ended December 31, 2018, 2017 and 2016,
approximately 99%, 97% and 97%, respectively, of our revenues were attributable to our operations in the Permian Basin. As a result of
this concentration, we may be disproportionately exposed to the impact of regional supply and demand factors, delays or interruptions of
production from wells in the Permian Basin caused by significant governmental regulation, processing or transportation capacity
constraints, market limitations, curtailment of production or interruption of the processing or transportation of oil and natural gas produced
from the wells in these areas. In addition, the effect of fluctuations on supply and demand may become more pronounced within specific
geographic oil and natural gas producing areas such as the Permian Basin, which may cause these

14

conditions to occur with greater frequency or magnify the effects of these conditions. Due to the concentrated nature of our operations, we
could experience any of the same conditions at the same time, resulting in a relatively greater impact on our revenue than they might have
on other companies that have more geographically diverse operations.

We are exposed to the credit risk of our customers, and any material nonpayment or nonperformance by our customers could adversely
affect our business, results of operations and financial condition.

We are subject to the risk of loss resulting from nonpayment or nonperformance by our customers. Our credit procedures and policies

may not be adequate to fully eliminate customer credit risk. If we fail to adequately assess the creditworthiness of existing or future
customers or unanticipated deterioration in their creditworthiness, any resulting increase in nonpayment or nonperformance by them and
our inability to re‑market or otherwise use the production could have a material adverse effect on our business, results of operations and
financial condition. The depressed oil and natural gas prices in 2015 and 2016 negatively impacted the financial condition and liquidity of
our customers, and future declines, sustained lower prices, or continued volatility could impact their ability to meet their financial
obligations to us.

We face significant competition that may cause us to lose market share.

The oilfield services industry is highly competitive and has relatively few barriers to entry. The principal competitive factors

impacting sales of our services are price, reputation and technical expertise, equipment and service quality and health and safety standards.
The market is also fragmented and includes numerous small companies capable of competing effectively in our markets on a local basis, as
well as several large companies that possess substantially greater financial and other resources than we do. Our larger competitors’ greater
resources could allow those competitors to compete more effectively than we can. For instance, our larger competitors may offer services
at below‑market prices or bundle ancillary services at no additional cost to our customers. We compete with large national and
multi‑national companies that have longer operating histories, greater financial, technical and other resources and greater name recognition
than we do. Several of our competitors provide a broader array of services and have a stronger presence in more geographic markets. In
addition, we compete with several smaller companies capable of competing effectively on a regional or local basis.

Some jobs are awarded on a bid basis, which further increases competition based on price. Pricing is often the primary factor in

determining which qualified contractor is awarded a job. The competitive environment may be further intensified by mergers and
acquisitions among oil and natural gas companies or other events that have the effect of reducing the number of available customers. As a
result of competition, we may lose market share or be unable to maintain or increase prices for our present services or to acquire additional
business opportunities, which could have a material adverse effect on our business, financial condition, results of operations and cash flows.

Our competitors may be able to respond more quickly to new or emerging technologies and services and changes in customer
requirements. The amount of equipment available may exceed demand, which could result in active price competition. In addition,
depressed commodity prices lower demand for hydraulic fracturing equipment, which results in excess equipment and lower utilization
rates. In addition, some exploration and production companies have commenced completing their wells using their own hydraulic fracturing
equipment and personnel. Any increase in the development and utilization of in‑house fracturing capabilities by our customers could
decrease the demand for our services and have a material adverse impact on our business.

Furthermore, competition among oilfield service and equipment providers is affected by each provider’s reputation for safety and

quality. We cannot assure that we will be able to maintain our competitive position.

New technology may cause us to become less competitive.

The oilfield services industry is subject to the introduction of new drilling and completion techniques and services using new
technologies, some of which may be subject to patent or other intellectual property protections. Although we believe our equipment and
processes currently give us a competitive advantage, as competitors and others use or develop new or comparable technologies in the
future, we may lose market share or be placed at a competitive disadvantage. Further, we may face competitive pressure to develop,
implement or acquire certain new

15

technologies at a substantial cost. Some of our competitors have greater financial, technical and personnel resources that may allow them to
enjoy technological advantages and develop and implement new products on a timely basis or at an acceptable cost. We cannot be certain
that we will be able to develop and implement new technologies or products on a timely basis or at an acceptable cost. Limits on our ability
to develop, effectively use and implement new and emerging technologies could have a material adverse effect on our business, financial
condition, prospects or results of operations.

Our business depends upon our ability to obtain specialized equipment, parts and key raw materials, including frac sand and chemicals,
from third‑party suppliers, and we may be vulnerable to delayed deliveries and future price increases.

We purchase specialized equipment, parts and raw materials (including, for example, frac sand, chemicals and fluid ends) from third
party suppliers and affiliates. At times during the business cycle, there is a high demand for hydraulic fracturing and other oil field services
and extended lead times to obtain equipment and raw materials needed to provide these services. Should our current suppliers be unable or
unwilling to provide the necessary equipment, parts or raw materials or otherwise fail to deliver the products timely and in the quantities
required, any resulting delays in the provision of our services could have a material adverse effect on our business, financial condition,
results of operations and cash flows. In addition, future price increases for this type of equipment, parts and raw materials could negatively
impact our ability to purchase new equipment, to update or expand our existing fleet, to timely repair equipment in our existing fleet or
meet the current demands of our customers.

Reliance upon a few large customers may adversely affect our revenue and operating results.

The majority of our revenue is generated from our hydraulic fracturing services. Due to the large percentage of our revenue historically

derived from our hydraulic fracturing services with recurring customers and the limited availability of our fracturing units, we have had
some degree of customer concentration. Our top ten customers represented approximately 85.5%, 87.0% and 83.0% of our consolidated
revenue for the years ended December 31, 2018, 2017 and 2016, respectively. It is likely that we will depend on a relatively small number
of customers for a significant portion of our revenue in the future. If a major customer fails to pay us, revenue would be impacted and our
operating results and financial condition could be harmed. Additionally, if we were to lose any material customer, we may not be able to
redeploy our equipment at similar utilization or pricing levels and such loss could have an adverse effect on our business until the
equipment is redeployed at similar utilization or pricing levels.

Certain of our completion services, particularly our hydraulic fracturing services, are substantially dependent on the availability of
water. Restrictions on our or our customers’ ability to obtain water may have an adverse effect on our financial condition, results of
operations and cash flows.

Water is an essential component of unconventional shale oil and natural gas production during both the drilling and hydraulic fracturing

processes. Over the past several years, certain of the areas in which we and our customers operate have experienced extreme drought
conditions and competition for water in such areas is growing. In addition, some state and local governmental authorities have begun to
monitor or restrict the use of water subject to their jurisdiction for hydraulic fracturing to ensure adequate local water supply. For instance,
some states require E&P companies to report certain information regarding the water they use for hydraulic fracturing and to monitor the
quality of groundwater surrounding some wells stimulated by hydraulic fracturing. Generally, our water requirements are met by our
customers from sources on or near their sites, but there is no assurance that our customers will be able to obtain a sufficient supply of water
from sources in these areas. Our or our customers’ inability to obtain water from local sources or to effectively utilize flowback water could
have an adverse effect on our financial condition, results of operations and cash flows.

We rely on a few key employees whose absence or loss could adversely affect our business.

Many key responsibilities within our business have been assigned to a small number of employees. The loss of their services could

adversely affect our business. In particular, the loss of the services of one or more members of our executive team, such as our Chief
Executive Officer, Chief Operating Officer, Chief Financial Officer, Chief Accounting Officer and General Counsel could disrupt our
operations. We do not maintain “key person” life

16

insurance policies on any of our employees. As a result, we are not insured against any losses resulting from the death of our key
employees.

If we are unable to employ a sufficient number of skilled and qualified workers, our capacity and profitability could be diminished and
our growth potential could be impaired.

The delivery of our services requires skilled and qualified workers with specialized skills and experience who can perform physically

demanding work. As a result of the volatility of the oilfield services industry and the demanding nature of the work, workers may choose to
pursue employment in fields that offer a more desirable work environment at wage rates that are competitive. Our ability to be productive
and profitable will depend upon our ability to employ and retain skilled workers. In addition, our ability to expand our operations depends
in part on our ability to increase the size of our skilled labor force. The demand for skilled workers is high, and the supply is limited. As a
result, competition for experienced oilfield service personnel is intense, and we face significant challenges in competing for crews and
management with large and well‑established competitors. A significant increase in the wages paid by competing employers could result in
a reduction of our skilled labor force, increases in the wage rates that we must pay, or both. If either of these events were to occur, our
capacity and profitability could be diminished and our growth potential could be impaired.

Our operations require substantial capital and we may be unable to obtain needed capital or financing on satisfactory terms, or at all,
which could limit our ability to grow.

The oilfield services industry is capital intensive. In conducting our business and operations, we have made, and expect to continue to
make, substantial capital expenditures. Our total capital expenditures incurred were approximately $592.6 million, $305.3 million and $46.0
million during the years ended December 31, 2018, 2017 and 2016. We have historically financed capital expenditures primarily with
funding from cash on hand, cash flow from operations, equipment and vendor financing and borrowings under our credit facilities. We may
be unable to generate sufficient cash from operations and other capital resources to maintain planned or future levels of capital expenditures
which, among other things, may prevent us from acquiring new equipment or properly maintaining our existing equipment. Further, any
disruptions or continuing volatility in the global financial markets may lead to an increase in interest rates or a contraction in credit
availability impacting our ability to finance our operations. This could put us at a competitive disadvantage or interfere with our growth
plans. Further, our actual capital expenditures could exceed our capital expenditure budget. In the event our capital expenditure
requirements at any time are greater than the amount we have available, we could be required to seek additional sources of capital, which
may include debt financing, joint venture partnerships, sales of assets, offerings of debt or equity securities or other means. We may not be
able to obtain any such alternative source of capital. We may be required to curtail or eliminate contemplated activities. If we can obtain
alternative sources of capital, the terms of such alternative may not be favorable to us. In particular, the terms of any debt financing may
include covenants that significantly restrict our operations. Our inability to grow as planned may reduce our chances of maintaining and
improving profitability.

Concerns over general economic, business or industry conditions may have a material adverse effect on our results of operations,
liquidity and financial condition.

Concerns over global economic conditions, geopolitical issues, interest rates, inflation, the availability and cost of credit and the United

States and foreign financial markets have contributed to increased economic uncertainty and diminished expectations for the global
economy. These factors, combined with volatility in commodity prices, business and consumer confidence and unemployment rates, have
precipitated an economic slowdown. Concerns about global economic growth have had a significant adverse impact on global financial
markets and commodity prices. If the economic climate in the United States or abroad deteriorates, worldwide demand for petroleum
products could diminish further, which could impact the price at which oil, natural gas and natural gas liquids can be sold, which could
affect the ability of our customers to continue operations and adversely impact our results of operations, liquidity and financial condition.

17

Our indebtedness and liquidity needs could restrict our operations and make us more vulnerable to adverse economic conditions.

Our existing and future indebtedness, whether incurred in connection with acquisitions, operations or otherwise, may adversely affect
our operations and limit our growth, and we may have difficulty making debt service payments on such indebtedness as payments become
due. Our level of indebtedness may affect our operations in several ways, including the following:

•

•

•

•

•

•

increasing our vulnerability to general adverse economic and industry
conditions;

the covenants that are contained in the agreements governing our indebtedness could limit our ability to borrow funds, dispose of
assets, pay dividends and make certain investments;

our debt covenants could also affect our flexibility in planning for, and reacting to, changes in the economy and in our
industry;

any failure to comply with the financial or other debt covenants, including covenants that impose requirements to maintain certain
financial ratios, could result in an event of default, which could result in some or all of our indebtedness becoming immediately
due and payable;

our level of debt could impair our ability to obtain additional financing, or obtain additional financing on favorable terms, in the
future for working capital, capital expenditures, acquisitions or other general corporate purposes; and

our business may not generate sufficient cash flow from operations to enable us to meet our obligations under our
indebtedness.

Restrictions in our ABL Credit Facility (as defined herein) and any future financing agreements may limit our ability to finance future
operations or capital needs or capitalize on potential acquisitions and other business opportunities.

The operating and financial restrictions and covenants in our credit facility and any future financing agreements could restrict our
ability to finance future operations or capital needs or to expand or pursue our business activities. For example, our ABL Credit Facility
restricts or limits our ability to:

•

•

•

•

•

grant
liens;

incur additional
indebtedness;

engage in a merger, consolidation or
dissolution;

enter into transactions with
affiliates;

sell or otherwise dispose of assets, businesses and
operations;

• materially alter the character of our business as currently conducted;

and

• make acquisitions, investments and capital

expenditures.

Furthermore, our ABL Credit Facility contains certain other operating and financial covenants. Our ability to comply with the
covenants and restrictions contained in the ABL Credit Facility may be affected by events beyond our control, including prevailing
economic, financial and industry conditions. If market or other economic conditions deteriorate, our ability to comply with these covenants
may be impaired. If we violate any of the restrictions, covenants, ratios or tests in our ABL Credit Facility, a significant portion of our
indebtedness may become immediately due and payable and our lenders’ commitment to make further loans to us may terminate. We might
not have, or be able to obtain, sufficient funds to make these accelerated payments. Any subsequent replacement of our ABL Credit Facility
or any new indebtedness could have similar or greater restrictions. Please

Credit Facility and Other Financing Arrangements .”

We may become more leveraged and our indebtedness could adversely affect our operations and financial condition.

Our business is capital intensive and we may seek to raise debt capital to fund our business and growth strategy. Indebtedness could
have negative consequences that could materially and adversely affect our business, financial condition, results of operations, cash flows
and prospects, such as:

•

•

•

•

•

requiring us to dedicate a substantial portion of our cash flow from operating activities to payments on our indebtedness,
thereby reducing the availability of cash flow to fund working capital, capital expenditures, research and development
efforts, potential strategic acquisitions and other general corporate purposes;

limiting our ability to obtain additional financing to fund growth, working capital or capital expenditures, or to fulfill debt
service requirements or other cash requirements;

increasing our vulnerability to economic downturns and changing market
conditions;

placing us at a competitive disadvantage relative to competitors that have less debt;
and

to the extent that our debt is subject to floating interest rates, increasing our vulnerability to fluctuations in market interest
rates.

Our operations are subject to unforeseen interruptions and hazards inherent in the oil and natural gas industry, for which we may not
be adequately insured and which could cause us to lose customers and substantial revenue.

Our operations are exposed to the risks inherent to our industry, such as equipment defects, vehicle accidents, fires, explosions,

blowouts, surface cratering, uncontrollable flows of gas or well fluids, pipe or pipeline failures, abnormally pressured formations and
various environmental hazards, such as oil spills and releases of, and exposure to, hazardous substances. For example, our operations are
subject to risks associated with hydraulic fracturing, including any mishandling, surface spillage or potential underground migration of
fracturing fluids, including chemical additives. In addition, our operations are exposed to potential natural disasters, including blizzards,
tornadoes, storms, floods, other adverse weather conditions and earthquakes. The occurrence of any of these events could result in
substantial losses to us due to injury or loss of life, severe damage to or destruction of property, natural resources and equipment, pollution
or other environmental damage, clean‑up responsibilities, regulatory investigations and penalties or other damage resulting in curtailment
or suspension of our operations. The cost of managing such risks may be significant. The frequency and severity of such incidents will
affect operating costs, insurability and relationships with customers, employees and regulators. In particular, our customers may elect not to
purchase our services if they view our environmental or safety record as unacceptable, which could cause us to lose customers and
substantial revenues.

Our insurance may not be adequate to cover all losses or liabilities we may suffer. Furthermore, we may be unable to maintain or
obtain insurance of the type and amount we desire at reasonable rates. As a result of market conditions, premiums and deductibles for
certain of our insurance policies have increased and could escalate further. In addition, sub‑limits have been imposed for certain risks. In
some instances, certain insurance could become unavailable or available only for reduced amounts of coverage. If we were to incur a
significant liability for which we are not fully insured, it could have a material adverse effect on our business, results of operations and
financial condition. In addition, we may not be able to secure additional insurance or bonding that might be required by new governmental
regulations. This may cause us to restrict our operations, which might severely impact our financial position.

Since hydraulic fracturing activities are part of our operations, they are covered by our insurance against claims made for bodily injury,

property damage and clean‑up costs stemming from a sudden and accidental pollution event.

19

However, we may not have coverage if we are unaware of the pollution event and unable to report the “occurrence” to our insurance
company within the time frame required under our insurance policy. In addition, these policies do not provide coverage for all liabilities,
and the insurance coverage may not be adequate to cover claims that may arise, or we may not be able to maintain adequate insurance at
rates we consider reasonable. A loss not fully covered by insurance could have a material adverse effect on our financial position, results of
operations and cash flows.

A terrorist attack or armed conflict could harm our business.

Terrorist activities, anti‑terrorist efforts and other armed conflicts involving the United States could adversely affect the U.S. and
global economies and could prevent us from meeting financial and other obligations. We could experience loss of business, delays or
defaults in payments from payors or disruptions of fuel supplies and markets if pipelines, production facilities, processing plants, refineries
or transportation facilities are direct targets or indirect casualties of an act of terror or war. Such activities could reduce the overall demand
for oil and natural gas, which, in turn, could also reduce the demand for our services. Terrorist activities and the threat of potential terrorist
activities and any resulting economic downturn could adversely affect our results of operations, impair our ability to raise capital or
otherwise adversely impact our ability to realize certain business strategies.

Increasing trucking regulations may increase our costs and negatively impact our results of operations.

In connection with our business operations, including the transportation and relocation of our hydraulic fracturing equipment and
shipment of frac sand, we operate trucks and other heavy equipment. As such, we operate as a motor carrier in providing certain of our
services and therefore are subject to regulation by the United States Department of Transportation and by various state agencies. These
regulatory authorities exercise broad powers, governing activities such as the authorization to engage in motor carrier operations, driver
licensing, insurance requirements, financial reporting and review of certain mergers, consolidations and acquisitions, and transportation of
hazardous materials (HAZMAT). Our trucking operations are subject to possible regulatory and legislative changes that may increase our
costs. Some of these possible changes include increasingly stringent environmental regulations, changes in the hours of service regulations
which govern the amount of time a driver may drive or work in any specific period, onboard black box recorder device requirements or
limits on vehicle weight and size.

Interstate motor carrier operations are subject to safety requirements prescribed by the United States Department of Transportation. To
a large degree, intrastate motor carrier operations are subject to state safety regulations that mirror federal regulations. Matters such as the
weight and dimensions of equipment are also subject to federal and state regulations. From time to time, various legislative proposals are
introduced, including proposals to increase federal, state, or local taxes, including taxes on motor fuels, which may increase our costs or
adversely impact the recruitment of drivers. We cannot predict whether, or in what form, any increase in such taxes applicable to us will be
enacted.

Certain motor vehicle operators require registration with the Department of Transportation. This registration requires an acceptable

operating record. The Department of Transportation periodically conducts compliance reviews and may revoke registration privileges
based on certain safety performance criteria that could result in a suspension of operations.

We are subject to environmental laws and regulations, and future compliance, claims, and liabilities relating to such matters may have
a material adverse effect on our results of operations, financial position or cash flows.

The nature of our operations, including the handling, transporting and disposing of a variety of fluids and substances, including

hydraulic fracturing fluids and other regulated substances, air emissions, and wastewater discharges exposes us to some risks of
environmental liability, including the release of pollutants from oil and natural gas wells and associated equipment to the environment. The
cost of compliance with these laws can be significant. Failure to properly handle, transport or dispose of these materials or otherwise
conduct our operations in accordance with these and other environmental laws could expose us to substantial liability for administrative,
civil and criminal penalties, cleanup and site restoration costs and liability associated with releases of such materials, damages to natural
resources and other damages, as well as potentially impair our ability to conduct our operations. Such liability is commonly on a strict, joint
and several liability basis, without regard to fault. Liability may be

20

imposed as a result of our conduct that was lawful at the time it occurred or the conduct of, or conditions caused by, prior operators or
other third parties. Neighboring landowners and other third parties may file claims against us for personal injury or property damage
allegedly caused by the release of pollutants into the environment. Environmental laws and regulations have changed in the past, and they
may change in the future and become more stringent. Current and future claims and liabilities may have a material adverse effect on us
because of potential adverse outcomes, defense costs, diversion of management resources, unavailability of insurance coverage and other
factors. The ultimate costs of these liabilities are difficult to determine and may exceed any reserves we may have established. If existing
environmental requirements or enforcement policies change, we may be required to make significant unanticipated capital and operating
expenditures.

The adoption of climate change legislation or regulations restricting emissions of greenhouse gases could result in increased operating
costs and reduced demand for oil and natural gas.

The EPA has determined that GHGs present an endangerment to public health and the environment because such gases contribute to

warming of the earth’s atmosphere and other climatic changes. Based on these findings, the EPA has adopted and implemented, and
continues to adopt and implement, regulations that restrict emissions of GHGs under existing provisions of the Clean Air Act (“CAA”). The
EPA also requires the annual reporting of GHG emissions from certain large sources of GHG emissions in the United States, including
certain oil and gas production facilities. The EPA has also taken steps to limit methane emissions from oil and gas production facilities. In
addition, the U.S. Congress has from time to time considered adopting legislation to reduce emissions of GHGs and almost one‑half of the
states have already taken legal measures to reduce emissions of GHGs primarily through the planned development of GHG emission
inventories and/or regional GHG cap and trade programs. And in December 2015, the United States joined the international community at
the 21st Conference of the Parties of the United Nations Framework Convention on Climate Change in Paris, France. The resulting Paris
Agreement calls for the parties to undertake “ambitious efforts” to limit the average global temperature, and to conserve and enhance sinks
and reservoirs of greenhouse gases. The Paris Agreement entered into force in November 2016. On June 1, 2017, President Trump
announced that the United States planned to withdraw from the Paris Agreement and to seek negotiations either to reenter the Paris
Agreement on different terms or establish a new framework agreement. The Paris Agreement provides for a four‑year exit process
beginning when it took effect in November 2016, which would resulting in an effective exit date of November 2020. The United States’
adherence to the exit process is uncertain and/or the terms on which the United States may reenter the Paris Agreement or a separately
negotiated agreement are unclear at this time.

Moreover, climate change may cause more extreme weather conditions and increased volatility in seasonal temperatures. Extreme
weather conditions can interfere with our operations and increase our costs, and damage resulting from extreme weather may not be fully
insured.

Federal and state legislative and regulatory initiatives relating to hydraulic fracturing could result in increased costs and additional
operating restrictions or delays.

Our hydraulic fracturing operations are a significant component of our business, and it is an important and common practice that is
used to stimulate production of hydrocarbons, particularly oil and natural gas, from tight formations, including shales. The process, which
involves the injection of water, sand and chemicals under pressure into formations to fracture the surrounding rock and stimulate
production, is typically regulated by state oil and natural gas commissions. However, federal agencies have asserted regulatory authority
over certain aspects of the process. For example, in May 2014, the EPA issued an Advanced Notice of Proposed Rulemaking seeking
comment on the development of regulations under the Toxic Substances Control Act to require companies to disclose information
regarding the chemicals used in hydraulic fracturing. Beginning in August 2012, the EPA issued a series of rules under the CAA that
establish new emission control requirements for emissions of volatile organic compounds and methane from certain oil and natural gas
production and natural gas processing operations and equipment. After several attempts to delay implementation, in September 2018 the
EPA issued a proposal to amend and reduce such requirements. In March 2015, the Bureau of Land Management (“BLM”) finalized a rule
governing hydraulic fracturing on federal lands. In June 2016, a federal district court judge in Wyoming struck down the final rule, finding
that the BLM lacked congressional authority to promulgate the rule. The BLM appealed that ruling. In September 2017, the U.S. Court of
Appeals for the Tenth Circuit dismissed the appeal and remanded with

21

directions to vacate the lower court’s opinion, leaving the final rule in place. The BLM initiated a rulemaking to rescind the final rule in
December 2017. Further, legislation to amend the Safe Drinking Water Act to repeal the exemption for hydraulic fracturing (except when
diesel fuels are used) from the definition of “underground injection” and require federal permitting and regulatory control of hydraulic
fracturing, as well as legislative proposals to require disclosure of the chemical constituents of the fluids used in the fracturing process,
have been proposed in recent sessions of Congress. Several states and local jurisdictions in which we or our customers operate also have
adopted or are considering adopting regulations that could restrict or prohibit hydraulic fracturing in certain circumstances, impose more
stringent operating standards and/or require the disclosure of the composition of hydraulic fracturing fluids.

More recently, federal and state governments have begun investigating whether the disposal of produced water into underground
injection wells has caused increased seismic activity in certain areas. In March 2016, the United States Geological Survey identified six
states with the most significant hazards from induced seismicity, including Oklahoma, Kansas, Texas, Colorado, New Mexico and
Arkansas. The United States Geological Survey also noted the potential for induced seismicity in Ohio and Alabama. In response to
concerns regarding induced seismicity, regulators in some states have imposed, or are considering imposing, additional requirements in the
permitting of produced water disposal wells or otherwise to assess any relationship between seismicity and the use of such wells. For
example, Oklahoma issued new rules for wastewater disposal wells in 2014 that imposed certain permitting and operating restrictions and
reporting requirements on disposal wells in proximity to faults and also, from time to time, has developed and implemented plans directing
certain wells where seismic incidents have occurred to restrict or suspend disposal well operations. In particular, the Oklahoma Corporation
Commission released well completion seismicity guidelines in December 2016 for operators in the SCOOP and STACK that call for
hydraulic fracturing operations to be suspended following earthquakes of certain magnitudes in the vicinity. In addition, in February 2017,
the Oklahoma Corporation Commission’s Oil and Gas Conservation Division issued an order limiting future increases in the volume of oil
and natural gas wastewater injected into the ground in an effort to reduce the number of earthquakes in the state. The Texas Railroad
Commission adopted similar rules in 2014. In addition, in December 2016, the EPA released its final report regarding the potential impacts
of hydraulic fracturing on drinking water resources, concluding that “water cycle” activities associated with hydraulic fracturing may
impact drinking water resources under certain circumstances such as water withdrawals for fracturing in times or areas of low water
availability, surface spills during the management of fracturing fluids, chemicals or produced water, injection of fracturing fluids into wells
with inadequate mechanical integrity, injection of fracturing fluids directly into groundwater resources, discharge of inadequately treated
fracturing wastewater to surface waters, and disposal or storage of fracturing wastewater in unlined pits. The results of these studies could
lead federal and state governments and agencies to develop and implement additional regulations.

Increased regulation of hydraulic fracturing and related activities (whether as a result of the EPA study results or resulting from other

factors) could subject us and our customers to additional permitting and financial assurance requirements, more stringent construction
specifications, increased monitoring, reporting and recordkeeping obligations, and plugging and abandonment requirements. New
requirements could result in increased operational costs for us and our customers, and reduce the demand for our services.

Conservation measures, commercial development and technological advances could reduce demand for oil and natural gas and our
services.

Fuel conservation measures, alternative fuel requirements, increasing consumer demand for alternatives to oil and natural gas,
technological advances in fuel economy and energy generation devices could reduce demand for oil and natural gas, resulting in reduced
demand for oilfield services. The impact of the changing demand for oil and natural gas services and products may have a material adverse
effect on our business, financial condition, results of operations and cash flows.

The commercial development of economically‑viable alternative energy sources and related products (such as electric vehicles, wind,
solar, geothermal, tidal, fuel cells and biofuels) could have a similar effect. In addition, certain U.S. federal income tax deductions currently
available with respect to oil and natural gas exploration and development, including the allowance of percentage depletion for oil and
natural gas properties, may be eliminated as a result of proposed legislation. Any future decreases in the rate at which oil and natural gas
reserves are

22

discovered or developed, whether due to the passage of legislation, increased governmental regulation leading to limitations, or prohibitions
on exploration and drilling activity, including hydraulic fracturing, or other factors, could have a material adverse effect on our business
and financial condition, even in a stronger oil and natural gas price environment.

We may be subject to claims for personal injury and property damage, which could materially adversely affect our financial condition
and results of operations.

We operate with most of our customers under master service agreements, or MSAs. We endeavor to allocate potential liabilities and
risks between the parties in the MSAs. Generally, under our MSAs, including those relating to our hydraulic fracturing services, we assume
responsibility for, including control and removal of, pollution or contamination which originates above surface and originates from our
equipment or services. Our customer assumes responsibility for, including control and removal of, all other pollution or contamination
which may occur during operations, including that which may result from seepage or any other uncontrolled flow of drilling fluids. We
may have liability in such cases if we are negligent or commit willful acts. Generally, our customers also agree to indemnify us against
claims arising from their employees’ personal injury or death to the extent that, in the case of our hydraulic fracturing operations, their
employees are injured or their properties are damaged by such operations, unless resulting from our gross negligence or willful misconduct.
Similarly, we generally agree to indemnify our customers for liabilities arising from personal injury to or death of any of our employees,
unless resulting from gross negligence or willful misconduct of the customer. In addition, our customers generally agree to indemnify us for
loss or destruction of customer‑owned property or equipment and in turn, we agree to indemnify our customers for loss or destruction of
property or equipment we own. Losses due to catastrophic events, such as blowouts, are generally the responsibility of the customer.
However, despite this general allocation of risk, we might not succeed in enforcing such contractual allocation, might incur an unforeseen
liability falling outside the scope of such allocation or may be required to enter into an MSA with terms that vary from the above
allocations of risk. Litigation arising from a catastrophic occurrence at a location where our equipment and services are being used may
result in our being named as a defendant in lawsuits asserting large claims. As a result, we may incur substantial losses which could
materially and adversely affect our financial condition and results of operation.

We are subject to cyber security risks. A cyber incident could occur and result in information theft, data corruption, operational
disruption and/or financial loss.

The oil and natural gas industry has become increasingly dependent on digital technologies to conduct certain processing activities. For

example, we depend on digital technologies to perform many of our services and process and record operational and accounting data. At
the same time, cyber incidents, including deliberate attacks or unintentional events, have increased. The U.S. government has issued public
warnings that indicate that energy assets might be specific targets of cyber security threats. Our technologies, systems and networks, and
those of our vendors, suppliers and other business partners, may become the target of cyberattacks or information security breaches that
could result in the unauthorized release, gathering, monitoring, misuse, loss or destruction of proprietary information, personal information
and other data, or other disruption of our business operations. In addition, certain cyber incidents, such as unauthorized surveillance, may
remain undetected for an extended period. Our systems and insurance coverage for protecting against cyber security risks, including
cyberattacks, may not be sufficient and may not protect against or cover all of the losses we may experience as a result of the realization of
such risks. As cyber incidents continue to evolve, we may be required to expend additional resources to continue to modify or enhance our
protective measures or to investigate and remediate the effects of cyber incidents.

Our certificate of incorporation and bylaws, as well as Delaware law, contain provisions that could discourage acquisition bids or
merger proposals, which may adversely affect the market price of our common stock.

Our certificate of incorporation authorizes our board of directors to issue preferred stock without shareholder approval. If our board of

directors elects to issue preferred stock, it could be more difficult for a third party to acquire us. In addition, some provisions of our
certificate of incorporation and bylaws could make it more difficult for a third party to acquire control of us, even if the change of control
would be beneficial to our shareholders, including:

23

•

•

•

•

•

limitations on the removal of
directors;

limitations on the ability of our shareholders to call special
meetings;

advance notice provisions for shareholder proposals and nominations for elections to the board of directors to be acted upon at
meetings of shareholders;

providing that the board of directors is expressly authorized to adopt, or to alter or repeal our bylaws;
and

establishing advance notice and certain information requirements for nominations for election to our board of directors or for
proposing matters that can be acted upon by shareholders at shareholder meetings.

We may grow through acquisitions and our failure to properly plan and manage those acquisitions may adversely affect our

performance.

We have completed and may in the future pursue, asset acquisitions or acquisitions of businesses. Any acquisition of assets or

businesses involves potential risks, including the failure to realize expected profitability, growth or accretion; environmental or regulatory
compliance matters or liability; title or permit issues; the incurrence of significant charges, such as impairment of goodwill, or property,
plant and equipment or restructuring charges; and the incurrence of unanticipated liabilities and costs for which indemnification is
unavailable or inadequate. The process of upgrading acquired assets to our specifications and integrating acquired assets or businesses may
also involve unforeseen costs and delays or other operational, technical and financial difficulties and may require a significant amount time
and resources and may divert management’s attention from existing operations or other priorities.

We must plan and manage any acquisitions effectively to achieve revenue growth and maintain profitability in our evolving market.

Any failure to manage acquisitions effectively or integrate acquired assets or businesses into our existing operations successfully, or to
realize the expected benefits from an acquisition or minimize any unforeseen operational difficulties, could have a material adverse effect
on our business, financial condition, prospects or results of operations.

Our ability to use our net operating loss carryforwards may be limited.

As of December 31, 2018, we had approximately $516.0 million of federal net operating loss carryforwards that will begin to expire in
2032 and state net operating losses of approximately $50.0 million that will begin to expire in 2024. Utilization of these net operating loss
carryforwards (“NOLs”) depends on many factors, including our future income, which cannot be assured. In addition, Section 382
(“Section 382”) of the Internal Revenue Code of 1986, as amended (the “Code”), generally imposes an annual limitation on the amount of
taxable income that may be offset by NOLs when a corporation has undergone an “ownership change” (as determined under Section 382).
Generally, a change of more than 50% in the ownership of a corporation’s stock, by value, over a three‑year period constitutes an
ownership change for U.S. federal income tax purposes. Any unused annual limitation may, subject to certain limitations, be carried over to
later years. We have experienced ownership changes, which may result in annual limitation under Section 382 determined by multiplying
the value of our stock at the time of the ownership change by the applicable long‑term tax‑exempt rate as defined in Section 382, increased
under certain circumstances as a result of recognizing built‑in gains in our assets existing at the time of the ownership change. The
limitations arising from ownership changes may prevent utilization of our NOLs prior to their expiration. Future ownership changes or
regulatory changes could further limit our ability to utilize our NOLs. To the extent we are not able to offset our future income with our
NOLs, this could adversely affect our operating results and cash flows if we attain profitability.

Future regulations relating to and interpretations of the recently enacted Tax Cuts and Jobs Act may have a material impact on our

financial condition and results of operations.

The Tax Cuts and Jobs Act of 2017, or the Tax Act, was signed into law on December 22, 2017. Among other things, the Tax Act

reduces the U.S. corporate tax rate from 35% to 21%, imposes significant additional limitations

24

on the deductibility of interest, and allows the expensing of capital expenditures. The Tax Act is highly complex and subject to
interpretation. The presentation of our financial condition and results of operations is based upon our current interpretation of the
provisions contained in the Tax Act. The Treasury Department and the Internal Revenue Service continue to release regulations relating to
and interpretive guidance of the legislation contained in the Tax Act. Any significant variance of our current interpretation of such
legislation from any future regulations or interpretive guidance could result in a change to the presentation of our financial condition and
results of operations and could negatively affect our business.

Our certificate of incorporation designates the Court of Chancery of the State of Delaware as the sole and exclusive forum for certain
types of actions and proceedings that may be initiated by our shareholders, which could limit our shareholders’ ability to obtain a
favorable judicial forum for disputes with us or our directors, officers, employees or agents.

Our certificate of incorporation provides that, unless we consent in writing to the selection of an alternative forum, the Court of
Chancery of the State of Delaware will, to the fullest extent permitted by applicable law, be the sole and exclusive forum for (i) any
derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of breach of a fiduciary duty owed by any of our
directors, officers, employees or agents to us or our shareholders, (iii) any action asserting a claim arising pursuant to any provision of the
Delaware General Corporation Law (the “DGCL”), our certificate of incorporation or our bylaws, or (iv) any action asserting a claim
against us that is governed by the internal affairs doctrine, in each such case subject to such Court of Chancery having personal jurisdiction
over the indispensable parties named as defendants therein. Any person or entity purchasing or otherwise acquiring any interest in shares of
our capital stock will be deemed to have notice of, and consented to, the provisions of our certificate of incorporation described in the
preceding sentence. This choice of forum provision may limit a shareholder’s ability to bring a claim in a judicial forum that it finds
favorable for disputes with us or our directors, officers, employees or agents, which may discourage such lawsuits against us and such
persons. Alternatively, if a court were to find these provisions of our certificate of incorporation inapplicable to, or unenforceable in respect
of, one or more of the specified types of actions or proceedings, we may incur additional costs associated with resolving such matters in
other jurisdictions, which could adversely affect our business, financial condition or results of operations.

We are subject to certain requirements of Section 404 of the Sarbanes-Oxley Act. If we fail to comply with the requirements of
Section 404 or if we or our auditors identify and report material weaknesses in internal control over financial reporting, our investors
may lose confidence in our reported information and our stock price may be negatively affected.

We are required to comply with certain provisions of Section 404 of the Sarbanes-Oxley Act of 2002, or Section 404. Section 404
requires that we document and test our internal control over financial reporting and issue our management’s assessment of our internal
control over financial reporting. This section also requires that our independent registered public accounting firm issue an attestation report
on such internal control. If we fail to comply with the requirements of Section 404, or if we or our auditors identify and report material
weaknesses in our internal control over financial reporting, the accuracy and timeliness of the filing of our annual and quarterly reports may
be materially adversely affected and could cause investors to lose confidence in our reported financial information, which could have a
negative effect on the trading price of our common stock. In addition, a material weakness in the effectiveness of our internal control over
financial reporting could result in an increased chance of fraud and the loss of customers, reduce our ability to obtain financing and require
additional expenditures to comply with these requirements, each of which could have a material adverse effect on our business, financial
condition, prospects, results of operations and cash flows.

Overview

Our Business

We are a growth‑oriented, Midland, Texas‑based oilfield services company providing hydraulic fracturing and other complementary
services to leading upstream oil and gas companies engaged in the exploration and production, or E&P, of North American unconventional
oil and natural gas resources. Our operations are primarily focused in the Permian Basin, where we have cultivated longstanding customer
relationships with some of the region’s most active and well‑capitalized E&P companies. Further, our fleet has been designed to handle the
highest intensity and most complex fracturing jobs. During the ended December 31, 2018, we continued our organic growth by purchasing
and deploying four newbuild hydraulic fracturing units, bringing our hydraulic horsepower, or HHP capacity to 905,000 HHP, or 20 fleets.
The Permian Basin is widely regarded as the most prolific oil‑producing area in the United States, and following our acquisition of pressure
pumping and related assets from Pioneer and Pioneer Pumping Services, we believe we are currently the largest provider of hydraulic
fracturing services in the region by HHP, with total horse power of 1,415,000 HHP, or 28 fleets.

Acquisition of Pioneer Pressure Pumping Assets

On December 31, 2018, we consummated the purchase of certain pressure pumping assets and real property from Pioneer and Pioneer

Pumping Services. Prior to the purchase, the pressure pumping assets exclusively provided integrated pressure pumping services to
Pioneer’s completion and production operations. The acquisition cost of the assets was comprised of $110.0 million of cash and 16.6
million shares of our common stock. In connection with the consummation of the transaction, we became a strategic long-term service
provider to Pioneer, providing pressure pumping and related services for a term of up to 10 years.

The pressure pumping assets acquired include eight hydraulic fracturing fleets with a total of 510,000 HHP, four coiled tubing units and

an associated equipment maintenance facility. Through this acquisition we expanded our existing presence in the Permian Basin, and
increased our pumping capacity by 56%, to 28 hydraulic fracturing fleets with a total of 1,415,000 HHP, further strengthening our position
as the largest pure-play provider of integrated well completion services in the Permian Basin.

•

•

Revenue increased $722.7 million, or 73.6%, to $1,704.6 million, as compared to $981.9 million for the year ended December 31,
2017, primarily as a result of the increase in our fleet size;

Cost of services (exclusive of depreciation and amortization) increased $456.8 million or 56.1% to $1,270.6 million, as compared
to $813.8 million for the year ended December 31, 2017, primarily as a result of the increase in fleet size, resulting in higher
activity levels. Cost of services as a percentage of revenue decreased to 74.5% in 2018 compared to 82.9% for the year ended
December 31, 2017;

General and administrative expenses, inclusive of stock-based compensation (“G&A”), increased $4.7 million, or 9.6% to $54.0
million, as compared to $49.2 million for the December 31, 2017. G&A as a percentage of revenue decreased to 3.2% in 2018
from 5.0% for the year ended December 31, 2017;

Diluted net income per common share was $2.00, compared to $0.16 for the year ended December 31,
2017.

2019 Outlook

In 2019, we continue to focus on providing best-in-class service to our customers, helping our customer improve their well economics

while continuing to enhance the Company’s profitability. We expect to achieve these objectives through:

•

continuing to enhance our dedicated customer model to drive production
efficiencies;

• maintaining full utilization of our hydraulic fracturing

fleets;

•

•

pursuing operational efficiencies and cost reduction
strategies;

pursuing expansion opportunities for our non-hydraulic fracturing
operations;

• maintaining our existing relationships with our vendors and developing strategic relationships with new suppliers to ensure

continuity;

•

exploring potential opportunities for mergers or acquisitions, focused on our growth, market opportunities and creating value to
our shareholders.

Our Assets and Operations

Through our pressure pumping segment, which includes cementing operations, we primarily provide hydraulic fracturing services
(inclusive of acidizing services) to E&P companies in the Permian Basin. Our modern hydraulic fracturing fleet has been designed to
handle Permian Basin specific operating conditions and the region’s increasingly high‑intensity well completions, which are characterized
by longer horizontal wellbores, more frac stages per lateral and increasing amounts of proppant per well. We have fully maintained our
equipment throughout the recent industry downturn to ensure optimal performance and reliability.

In addition to our core pressure pumping segment operations, we also offer a suite of complementary well completion and production

services, including coiled tubing and flowback services. We believe these complementary services create operational efficiencies for our
customers and allow us to capture a greater portion of their capital spending across the lifecycle of a well. Additionally, we believe that
these complementary services should benefit from a continued industry recovery and that we are well positioned to continue expanding
these offerings in response to our customers’ increasing service needs and spending levels.

How We Generate Revenue

We generate revenue primarily through our pressure pumping segment, and more specifically, by providing hydraulic fracturing
services to our customers. We own and operate a fleet of mobile hydraulic fracturing units and other auxiliary equipment to perform
fracturing services. We also provide personnel and services that are tailored to meet each of our customers’ needs. We charge our
customers on a per‑job basis, in which we set pricing terms after receiving full specifications for the requested job, including the lateral
length of the customer’s wellbore, the number of frac stages per well, the amount of proppant to be employed and other parameters of
the job.

In addition to hydraulic fracturing services, we generate revenue through the complementary services that we provide to our customers,

including cementing, coiled tubing and flowback services. These complementary services are provided through various contractual
arrangements, including on a turnkey contract basis, in which we set a price to perform a particular job, or a daywork contract basis, in
which we are paid a set price per day for our services. We are also sometimes paid by the hour for these complementary services.

Our revenue, profitability and cash flows are highly dependent upon prevailing crude oil prices and expectations about future

prices. For many years, oil prices and markets have been extremely volatile. Prices are affected by many factors beyond our control. West
Texas Intermediate (“WTI”) oil prices which declined significantly in 2015 and 2016, but recovered somewhat during 2017 and 2018. The
average WTI oil prices per barrel was $65.1, $50.8 and $43.3 for the years ended December 31, 2018, 2017 and 2016, respectively. As a
result of the recent recovery in oil prices, our industry has experienced a significant increase in both drilling and pressure pumping activity
levels. Looking forward, if oil prices increase, we believe U.S. rig counts will also increase, which may result in an increase in demand for
drilling and pressure pumping services. Higher oil and natural gas prices do not necessarily result in increased activity because demand for
our services is generally driven by our customers’ expectations of future oil and natural gas prices, as well as rig count.

The historical average Permian Basin rig counts based on the weekly Baker Hughes Incorporated rig count information were as

Costs of Conducting our Business

The principal direct costs involved in operating our business are expendables, other direct costs, and direct labor costs. Generally, we
price each job to reflect a predetermined margin over our expendables and direct labor costs. Our fixed costs are relatively low and a large
portion of the costs described below are only incurred as we perform jobs for our customers.

Expendables. Expendables are the largest expenses incurred, and include the product and freight costs associated with proppant,

chemicals and other consumables used in our pressure pumping and other operations. These costs comprise a substantial variable
component of our service costs, particularly with respect to the quantity and quality of sand and chemicals demanded when providing
hydraulic fracturing services. Expendable product costs comprised approximately 56.0%, 61.3% and 61.0% of total costs of service for the
years ended December 31, 2018, 2017 and 2016, respectively. The decrease in our expendable product cost as a percentage of revenue in
2018 is primarily attributable to the increase in the number of customers self-sourcing these expendables and an increase in the use of less
expensive regional sand.

Other Direct Costs. We incur other direct expenses related to our service offerings, including the costs of fuel, repairs and

maintenance, general supplies, equipment rental and other miscellaneous operating expenses. Fuel is consumed both in the operation and
movement of our hydraulic fracturing fleet and other equipment. Repairs and maintenance costs are expenses directly related to upkeep of
equipment, which have been amplified by the demand for higher horsepower jobs. Capital expenditures to upgrade or extend the useful life
of equipment are not included in other direct costs. Other direct costs were 30.9%, 26.5% and 24.4% of total costs of service for the years
ended December 31, 2018, 2017 and 2016, respectively.

Direct Labor Costs. Payroll and benefit expenses related to our crews and other employees that are directly attributable to the effective
delivery of services are included in our operating costs. Direct labor costs amounted to 13.1%, 12.2% and 14.5% of total costs of service for
the years ended December 31, 2018, 2017 and 2016, respectively.

How We Evaluate Our Operations

Our management uses a variety of financial and operating metrics to evaluate and analyze the performance of our business, including

Adjusted EBITDA or Adjusted EBITDA margin.

Adjusted EBITDA and Adjusted EBITDA margin

We view Adjusted EBITDA or Adjusted EBITDA margin as important indicators of performance. We define EBITDA as our net

income (loss), before (i) interest expense, (ii) income taxes and (iii) depreciation and amortization. We define Adjusted EBITDA as
EBITDA, plus (i) loss/(gain) on disposal of assets, (ii) (gain) on extinguishment of debt, (iii) stock based compensation, and (iv) other
unusual or non‑recurring (income)/expenses, such as impairment and costs related to our initial public offering. Adjusted EBITDA margin
reflects our Adjusted EBITDA as a percentage of our revenues.

Adjusted EBITDA or Adjusted EBITDA margin are supplemental measures utilized by our management and other users of our
financial statements such as investors, commercial banks, and research analysts, to assess our financial performance because it allows us
and other users to compare our operating performance on a consistent basis across periods by removing the effects of our capital structure
(such as varying levels of interest expense), asset base (such as depreciation and amortization), nonrecurring (income)/expenses and items
outside the control of our management team (such as income tax rates). Adjusted EBITDA and Adjusted EBITDA margin have limitations
as analytical tools and should not be considered as an alternative to net income/(loss), operating income/(loss), cash flow from operating
activities or any other measure of financial performance presented in accordance with generally accepted accounting principles in the
United States of America (“GAAP”).

34

Note Regarding Non‑GAAP Financial Measures

Adjusted EBITDA and Adjusted EBITDA margin are usually not financial measures presented in accordance with GAAP (“non-

GAAP”), except when specifically required to be disclosed by GAAP in the financial statements. We believe that the presentation
of Adjusted EBITDA or Adjusted EBITDA margin provide useful information to investors in assessing our financial condition and results
of operations because it allows them to compare our operating performance on a consistent basis across periods by removing the effects of
our capital structure, asset base, nonrecurring expenses (income) and items outside the control of the Company. Net income is the GAAP
measure most directly comparable to Adjusted EBITDA.  Adjusted EBITDA or Adjusted EBITDA margin should not be considered as
alternatives to the most directly comparable GAAP financial measure. Each of these non-GAAP financial measures has important
limitations as analytical tools because they exclude some, but not all, items that affect the most directly comparable GAAP financial
measures. You should not consider Adjusted EBITDA or Adjusted EBITDA margin in isolation or as a substitute for an analysis of our
results as reported under GAAP. Because Adjusted EBITDA or Adjusted EBITDA margin may be defined differently by other companies
in our industry, our definitions of these non-GAAP financial measures may not be comparable to similarly titled measures of other
companies, thereby diminishing their utility.

Results of Operations

We conduct our business through five operating segments: hydraulic fracturing, cementing, coil tubing, flowback and drilling. For

reporting purposes, the hydraulic fracturing (which now includes our acidizing operations) and cementing operating segments are
aggregated into our one reportable segment, pressure pumping. On August 31, 2018, we divested our surface air drilling segment in order
to continue to position ourselves as a Permian Basin-focused pressure pumping business because we believe the pressure pumping market
in the Permian Basin offers more supportive long-term growth fundamentals. In addition, with increased focus on our pressure pumping
operations, we expect revenues and costs of services related to our drilling operating segment to comprise a lower percentage of total
revenues and total costs of service in future results of operations when compared to historic results. Accordingly, we anticipate the financial
significance of our drilling segment relative to the financial results from pressure pumping and other service offerings to continue to
decline.

Revenue.  Revenue increased 73.6%, or $722.7 million, to $1,704.6 million for the year ended December 31, 2018, as compared to
$981.9 million for the year ended December 31, 2017. The increase was primarily attributable to the increase in activity levels resulting
from increase in fleet size and demand for our services. Our pressure pumping segment revenues increased 75.5%, or $713.4 million for the
year ended December 31, 2018, as compared to the year ended December 31, 2017. Revenues from services other than pressure pumping
increased 25.3%, or $9.3 million, for the year ended December 31, 2018, as compared to the year ended December 31, 2017. The increase
in revenues from services other than pressure pumping during the year ended December 31, 2018, was primarily attributable to the increase
in demand for our flowback and coil tubing services.

Cost of Services.  Cost of services increased 56.1%, or $456.8 million, to $1,270.6 million for the year ended December 31, 2018, from

$813.8 million during the year ended December 31, 2017. Cost of services in our pressure pumping segment increased $451.9 million
during the year ended December 31, 2018, as compared to the year ended December 31, 2017. The increases were primarily attributable to
higher activity levels, coupled with an increase in personnel headcount following the increased activity levels. As a percentage of pressure
pumping segment revenues, pressure pumping cost of services decreased to 74.5% for the year ended December 31, 2018, as compared to
83.0% for the year ended December 31, 2017. The decrease in cost of services as a percentage of revenue in our pressure pumping segment
is attributed to the increased revenue from operational efficiencies and our cost control initiatives, which resulted in significantly higher
realized Adjusted EBITDA margins during the year ended December 31, 2018.

General and Administrative Expenses.  General and administrative expenses increased 9.6%, or $4.7 million, to $54.0 million for the

year ended December 31, 2018, as compared to $49.2 million for the year ended December 31, 2017. The net increase was primarily
attributable to increases in payroll, insurance, property taxes, legal and professional fees, traveling expenses, subscriptions and dues and
other general and administrative expenses totaling $14.3 million, and offset by a decrease in stock compensation expense of $4.0 million
and deferred IPO cash bonus of $5.6 million.

Depreciation and Amortization.  Depreciation and amortization increased 58.4%, or $32.5 million, to $88.1 million for the year ended

December 31, 2018, as compared to $55.6 million for the year ended December 31, 2017. The increase was primarily attributable to
additional property and equipment purchased and put into service in the year ended December 31, 2018. We calculate depreciation of
property and equipment using the straight-line method.

Loss on Disposal of Assets.  Loss on the disposal of assets increased 51.5%, or $20.1 million, to $59.2 million for the year ended
December 31, 2018, as compared to $39.1 million for the year ended December 31, 2017. The increase was primarily attributable to
increase in our fleet size and greater intensity of jobs completed.

Interest Expense.  Interest expense decreased 6.2%, or $0.5 million, to $6.9 million for the year ended December 31, 2018, as

compared to $7.3 million for the year ended December 31, 2017. The decrease in interest expense was primarily attributable to a reduction
of our average debt balance in 2018 compared to 2017.

Other Expense.  Other expense was $0.7 million for the year ended December 31, 2018, as compared to $1.0 million for the year
ended December 31, 2017. The decrease was primarily attributable to a decrease in lenders related expenses, non-recurring listing related
expenses, and the loss associated with the change in the fair value of our extinguished interest rate swap liability.

Income Tax Expense.  Income tax expense was  $51.3 million for the year ended December 31, 2018, as compared to $3.1 million for
the year ended December 31, 2017. The increase in our provision for income tax expense is primarily attributable to the increase in book
income in 2018 compared to 2017. Additionally, the income tax expense during the year ended  December 31, 2017, included a one-time
deferred tax benefit offset of $3.4 million, resulting from the U.S. government enacted tax legislation commonly referred to as the Tax Cuts
and Jobs Act (“Tax Act”).

(4) The non‑GAAP financial measure of Adjusted EBITDA margin for the pressure pumping segment is calculated by taking Adjusted EBITDA for the pressure

pumping segment as a percentage of our revenues for the pressure pumping segment.

Revenue.  Revenue increased 124.7%, or $544.9 million, to $981.9 million for the year ended December 31, 2017, as compared to
$436.9 million for the year ended December 31, 2016. The increase was primarily attributable to the increase in customer activity, fleet
size and demand for our services, which led to an increase in pricing for our hydraulic fracturing and other services. Our pressure pumping
segment revenues increased 131.1%, or $536.0 million for the year ended December 31, 2017, as compared to the year ended
December 31, 2016. Revenues from services other than pressure pumping increased 32.0%, or $8.9 million, for the year ended
December 31, 2017, as compared to the year ended December 31, 2016. The increase in revenues from services other than pressure
pumping during the year ended December 31, 2017 was primarily attributable to the increase in revenues and customer demand for our
flowback, coil tubing and surface drilling services, offset by the decrease in revenue from idling of our drilling rigs.

Cost of Services.  Cost of services increased 101.4%, or $409.7 million, to $813.8 million for the year ended December 31, 2017, from

$404.1 million during the year ended December 31, 2016. Cost of services in our pressure pumping segment increased $404.5 million
during the year ended December 31, 2017, as compared to the year ended December 31, 2016. The increases were primarily attributable to
higher activity levels, coupled with an increase in personnel headcount following the increased activity levels. As a percentage of pressure
pumping segment revenues, pressure pumping cost of services decreased to 83.0% for the year ended December 31, 2017, as compared to
92.9% for the year ended December 31, 2016. The decrease in cost of services as a percentage of revenue for the pressure pumping
segment resulted from greater pricing power as demand for our services increased, without a corresponding increase in certain costs, which
resulted in significantly higher realized Adjusted EBITDA margins during the year ended December 31, 2017.

General and Administrative Expenses.  General and administrative expenses increased 84.9%, or $22.6 million, to $49.2 million for the

year ended December 31, 2017, as compared to $26.6 million for the year ended December 31, 2016. The net increase was primarily
attributable to increases in payroll, insurance, advertising, communication, office expense, travel and legal costs, totaling $8.3 million, and
an IPO bonus of $8.4 million to key employees, along with $7.8 million increase in stock compensation recorded during the year ended
December 31, 2017, and offset by a decrease in property taxes of $1.6 million, and other remaining general and administrative expenses of
$0.3 million. General and administrative expenses as a percentage of total revenues decreased to 5.0% for the year ended December 31,
2017, as compared to 6.1% for the year ended December 31, 2016, excluding non-recurring deferred IPO bonus of $8.4 million and stock
compensation expense of $6.8 million, general and administrative expenses as a percentage of total revenues decreased to 3.5% for the year
ended December 31, 2017, as compared to 6.1% for the year ended December 31, 2016. The decrease in general and administrative
expenses as a percentage of total revenue is as a result of the higher revenue during the year ended December 31, 2017.

Depreciation and Amortization.  Depreciation and amortization increased 27.8%, or $12.1 million, to $55.6 million for the year ended

December 31, 2017, as compared to $43.5 million for the year ended December 31, 2016. The increase was primarily attributable to
additional property and equipment purchased and put into service in the year ended December 31, 2017. We calculate depreciation of
property and equipment using the straight-line method.

Property and Equipment Impairment Expense. There was no property and equipment impairment expense during the year ended
December 31, 2017, compared to $6.3 million during the year ended December 31, 2016. The non‑cash impairment expense in 2016 was
associated with our drilling rigs, and was recognized as a result of depressed commodity prices and a negative future near‑term outlook for
these assets.

Goodwill Impairment Expense. There was no goodwill impairment expense during the year ended December 31, 2017, compared to

$1.2 million during the year ended December 31, 2016. The non‑cash goodwill impairment expense in 2016 was as a result of the
write‑down of goodwill related to our surface drilling reporting unit.

Loss on Disposal of Assets.  Loss on the disposal of assets increased 73.5%, or $16.6 million, to $39.1 million for the year ended
December 31, 2017, as compared to $22.5 million for the year ended December 31, 2016. The increase was primarily attributable to greater
service intensity of jobs completed, coupled with higher fleet size, activity levels and utilization of our equipment.

Interest Expense.  Interest expense decreased 64.0%, or $13.0 million, to $7.3 million for the year ended December 31, 2017, as

compared to $20.4 million for the year ended December 31, 2016. The decrease in interest expense was primarily attributable to a reduction
in our average debt balance during 2017 due to the early retirement of our term loan and revolving credit facility in the first quarter of 2017.

Gain on Extinguishment of Debt.  There was no debt extinguishment gain or loss during the year ended December 31, 2017, compared

to the gain on extinguishment of debt, net of cost, of $7.0 million during the year ended December 31, 2016. The gain on extinguishment
of debt during 2016 was as a result of the auction process with our lenders to repurchase $37.5 million of our term loan at a 20% discount
to par value.

40

Other Expense.  Other expense was $1.0 million for the year ended December 31, 2017, as compared to $0.3 million for the year
ended December 31, 2016. The increase was primarily attributable to an increase in lenders related expenses, non-recurring listing related
expenses, and partially offset by an increase in the unrealized gain resulting from the change in the fair value of our interest rate swap
liability at December 31, 2017 compared to December 31, 2016.

Income Tax Expense/(Benefit).  Income tax expense was $3.1 million for the year ended December 31, 2017, compared to income tax
benefit of $28.0 million, for the year ended December 31, 2016. The change from an income tax benefit to income tax expense is primarily
due to the Company’s reporting income before taxes during the year ended December 31, 2017, compared to a loss before taxes recorded
during the year ended December 31, 2016. The income before taxes generated is attributable to the increase in our revenue during the year
ended December 31, 2017, compared to December 31, 2016. Additionally, the income tax expense during the year ended December 31,
2017, included a one-time deferred tax benefit offset of $3.4 million, resulting from the U.S. government enacted tax legislation commonly
referred to as the Tax Cuts and Jobs Act (“Tax Act”). 

Liquidity and Capital Resources

Our liquidity is currently provided by (i) existing cash balances, (ii) operating cash flows and (iii) borrowings under our ABL Credit
Facility. Our primary uses of cash will be to continue to fund our operations, support growth opportunities and satisfy debt payments. As of
December 31, 2018, our total liquidity consists of cash and cash equivalents of $132.7 million, and $125.0 million of availability under our
ABL Credit Facility.

There can be no assurance that operations and other capital resources will provide cash in sufficient amounts to maintain planned or

future levels of capital expenditures. Future cash flows are subject to a number of variables, and are highly dependent on the drilling,
completion, and production activity by our customers, which in turn is highly dependent on oil and gas prices. Depending upon market
conditions and other factors, we may issue equity and debt securities or take other actions necessary to fund our business or meet our future
long-term liquidity requirements.

Cash and Cash Flows

The following table sets forth our net cash provided by (used in) operating, investing and financing activities during the year at

December 31, 2018, 2017 and 2016, respectively.

Net cash provided by operating activities was $393.1 million for the year ended December 31, 2018, as compared to $109.3 million for

the year ended December 31, 2017. The net increase of $283.8 million was primarily due to the increase in our revenue generating assets
(fleet size), which has resulted in increases in revenue and net income in the year, offset by our working capital needs resulting from higher
fleet size and expanding activity levels.

Net cash provided by operating activities was $109.3 million for the year ended December 31, 2017, as compared to $10.7 million for

the year ended December 31, 2016. The net increase of $98.6 million was primarily due to an increase in revenue and net income in the
year, resulting from an increase in customer activity, fleet size and demand for our services, and partially offset by the increase in our
working capital needs resulting from higher fleet size and expanding activity levels.

Investing Activities

Net cash used in investing activities decreased to $280.6 million for the year ended December 31, 2018, from $281.5 million for the

year ended December 31, 2017. The slight decrease was primarily attributable to the decrease in cash payment for capital expenditures
during the year ended December 31, 2018, compared to the year ended December 31, 2017.

Net cash used in investing activities increased to $281.5 million for the year ended December 31, 2017, from $41.7 million for the year

ended December 31, 2016. The increase was primarily attributable to the additional hydraulic fracturing units and other ancillary
equipment purchased and a marginal increase in maintenance capital expenditures, during the year ended December 31, 2017, compared to
the year ended December 31, 2016.

Financing Activities

Net cash used in financing activities was $3.7 million for the year ended December 31, 2018, compared to net cash provided of $62.6

million for the year ended December 31, 2017. Our net cash used in financing activities during the year ended December 31, 2018 was
primarily driven by cash used for repayment of borrowings of $80.9 million, repayment of insurance financing of $4.5 million, debt
issuance cost of $1.7 million, which was partially offset by cash proceeds from insurance financing $5.8 million and borrowings of $77.4
million. Our net cash provided by financing activities during the year ended December 31, 2017 was primarily from borrowings of $60.0
million, insurance financing proceeds of $4.1 million and initial public offerings (IPO) proceeds of $185.5 million, partially offset by
repayment of borrowings of $166.5 million, repayment of insurance financing of $3.8 million, debt issuance of $1.7 million and IPO costs
of $15.1 million.

Net cash provided by financing activities was $62.6 million for the year ended December 31, 2017, compared to $130.3 million for the
year ended December 31, 2016. The net decrease in cash provided from financing activities was primarily attributable to the repayment of
borrowings $166.5 million, repayment of insurance financing of $3.8 million, debt issuance cost of $1.7 million, payment of IPO costs of
$15.1 million and offset by the receipt of $185.5 million of IPO proceeds, insurance financing proceeds of $4.1 million and proceeds from
borrowings of $60.0 million during the year ended December 31, 2017, compared to net cash used of $71.3 million for repayment of
borrowings, repayment of insurance financing of $4.5 million, payment of preferred equity financing costs of $7.5 million, debt
extinguishment, debt issuance and IPO costs of $1.0 million, offset by insurance financing proceeds of $4.1 million, equity capitalization
proceeds of $40.4 million and proceeds from preferred equity capitalization of $170.0 million during the year ended December 31, 2016.

Credit Facility and Other Financing Arrangements

ABL Credit Facility

On March 22, 2017, we entered into a new revolving credit facility with a $150 million borrowing capacity, or the ABL Credit Facility.

Borrowings under the ABL Credit Facility accrue interest based on a three-tier pricing grid tied to availability, and we may elect for loans
to be based on either LIBOR or base rate, plus the applicable margin, which ranges from 1.75% to 2.25% for LIBOR loans and 0.75% to
1.25% for base rate loans, with no LIBOR floor. Borrowings under the ABL Credit Facility are secured by a first priority lien and security
interest in substantially all assets of the Company. The ABL Credit Facility has a term of 5 years and a borrowing base of 85% of eligible
accounts receivable less customary reserves. Under this facility we are required to comply, subject to certain exceptions and materiality
qualifiers, with certain customary affirmative and negative covenants, including, but not limited to, covenants pertaining to our ability to
incur liens, indebtedness, changes in the nature of our business, mergers and other fundamental changes, disposal of assets, investments
and restricted payments, amendments to our organizational documents or accounting policies, prepayments of certain debt, dividends,
transactions with affiliates, and certain other activities. In addition, the ABL Credit Facility includes a Springing Fixed Charge Coverage
Ratio of 1.0x when excess availability is less than the greater of (i) 10% of the lesser of the facility size and the Borrowing Base and (ii)
$12 million. The ABL has a commitment fee of 0.375%, which reduces to 0.25% if utilization is greater than 50% of the borrowing base.

42

On February 22, 2018, we entered into a first amendment with our lenders to increase the capacity of the ABL Credit Facility. The
amendment increased total capacity under the facility from $150.0 million to $200.0 million. The first amendment to ABL Credit Facility
modified the Springing Fixed Charge Coverage Ratio to apply when excess availability is less than the greater of (i) 10% of the lesser of
the facility size and the Borrowing Base and (ii) $15 million.

On December 19, 2018, we entered into a second amendment with our lenders to further increase the capacity of the ABL Credit
Facility. The second amendment increased total capacity under the facility from $200.0 million to $300.0 million and extended the maturity
date of the ABL Credit Facility from March 22, 2022 until December 19, 2023. The second amendment to the ABL Credit Facility further
modified the Springing Fixed Charge Coverage Ratio to apply when excess availability is less than the greater of (i) 10% of the lesser of
the facility size and the Borrowing Base and (ii) $22.5 million.

Equipment Financing Arrangements

On November 24, 2015, we entered into a 36‑month equipment financing arrangement for three hydraulic fracturing units, and
received proceeds of $25.0 million. A portion of the proceeds were used to pay off manufacturer notes, and the remainder was used for
additional liquidity. As of December 31, 2018, we have fully repaid all outstanding balance and met all obligations under this financing
arrangement

On June 30, 2017, we entered into a financing arrangement for the purchase of light vehicles. As of December 31, 2018, we have fully

repaid all outstanding balance and met all obligations under this financing arrangement.

Off Balance Sheet Arrangements

We had no off balance sheet arrangements as of  December 31, 2018.

Capital Requirements

Capital expenditures incurred were $592.6 million during the year ended December 31, 2018, as compared to $305.3 million during the

year ended December 31, 2017. The increase was primarily attributable to our acquisition of Pioneer’s pressure pumping assets, which
includes eight hydraulic fracturing fleets, four coiled tubing units and an associated equipment maintenance building.

Capital expenditures incurred were $305.3 million during the year ended December 31, 2017 as compared to $46.0 million during the

year ended December 31, 2016. The increase was primarily attributable to additional property and equipment purchased.

Recent Accounting Pronouncements

Disclosure concerning recently issued accounting standards is incorporated by reference to Note 2 of our Consolidated Financial

Statements contained in this Form 10-K.

Critical Accounting Policies and Estimates

The discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements,
which have been prepared in accordance with accounting principles generally acceptable in the United States of America. The preparation
of these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the
disclosure of contingent assets and liabilities at the dates of the financial statements and the reported revenues and expenses during the
years. We evaluate these estimates and assumptions on an ongoing basis and base our estimates on historical experience, current conditions
and various other assumptions that we believe to be reasonable under the circumstances. The results of these estimates form the basis for
making judgments about the carrying values of assets and liabilities as well as identifying and assessing the accounting treatment with
respect to commitments and contingencies. Our actual results may materially differ from these estimates.

Listed below are the accounting policies that we believe are critical to our financial statements due to the degree of uncertainty

regarding the estimates or assumptions involved, and that we believe are critical to the understanding of our operations.

Property and Equipment

Our property and equipment are recorded at cost, less accumulated depreciation.

Upon sale or retirement of property and equipment, the cost and related accumulated depreciation are removed from the balance sheet

and the net amount, less proceeds from disposal, is recognized as a gain or loss in earnings.

We retired certain components of equipment rather than entire pieces of equipment, which resulted in a net loss on disposal of assets of

$59.2 million, $39.1 million and $22.5 million for the years ended December 31, 2018, 2017 and 2016, respectively.

Depreciation of property and equipment is provided on the straight‑line method over estimated useful lives as shown in the table
below. The estimated useful lives and salvage values of property and equipment is subject to key assumptions such as maintenance,
utilization and job variation. Unanticipated future changes in these assumptions could negatively or positively impact our net income. A
10% change in the useful lives of our property and equipment would have resulted in approximately $8.8 million impact on pre-tax income
during the year ended December 31, 2018.

Impairment of Long-Lived Assets

Indefinite
5 - 30 years
1 ‑ 5 years
1 ‑ 20 years
5 ‑ 20 years

In accordance with the Financial Accounting Standards Board Accounting Standards Codification (ASC) 360 regarding Accounting for

the Impairment or Disposal of Long‑Lived Assets, we review the long‑lived assets to be held and used whenever events or circumstances
indicate that the carrying value of those assets may not be recoverable. An impairment loss is indicated if the sum of the expected future
undiscounted cash flows attributable

44

to the assets is less than the carrying amount of such assets. In this circumstance, we recognize an impairment loss for the amount by which
the carrying amount of the asset exceeds the estimated fair value of the asset. Our cash flow forecasts require us to make certain
judgements regarding long‑term forecasts of future revenue and costs and cash flows related to the assets subject to review. The significant
assumption in our cash flow forecasts is our future growth expectations. The significant assumption is uncertain in that it is driven by
future demand for our services and utilization which could be impacted by crude oil market prices, future market conditions and
technological advancements. Our fair value estimates for certain long‑lived assets require us to use significant other observable inputs
among others, including significant assumptions related to market approach based on recent auction sales or selling prices of comparable
equipment. The estimates of fair value are also subject to significant variability, are sensitive to changes in market conditions, and are
reasonably likely to change in the future. No events or changes in circumstances occurred that would indicate an impairment of our
property and equipment during the year ended December 31, 2018.

If the crude oil market declines or the demand for vertical drilling does not recover, and if the equipment remains idle or under‑utilized,
the estimated fair value of such equipment may decline, which could result in future impairment charges. Though the impacts of variations
in any of these factors can have compounding or off‑setting impacts, a 10% decline in the estimated fair value of our drilling assets at
December 31, 2018 would result in additional impairment of $0.5 million, and a 10% decline in the estimated future cash flows for our
other asset groups would not indicate an impairment.

Income Taxes

Income taxes are accounted for under the asset and liability method, which requires the recognition of deferred tax assets and liabilities

for the expected future tax consequences of events that have been included in the consolidated financial statements. Under this method,
deferred tax assets and liabilities are determined on the basis of differences between the consolidated financial statements and tax bases of
assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in
tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date.

We recognize deferred tax assets to the extent that we believe these assets are more likely than not to be realized. In making such a

determination, we consider all positive and negative evidence, including future reversals of existing taxable temporary differences,
projected future taxable income, and the results of recent operations. If we determine that we would be able to realize our deferred tax
assets in the future in excess of their net recorded amount, we would make an adjustment to the deferred tax asset valuation allowance,
which would reduce the provision for income taxes. In determining the reasonableness of our valuation allowance as of December 31,
2018, we have considered and made judgments and estimates regarding estimated future taxable income. These estimates and judgments
include some degree of uncertainty and changes in these estimates and assumptions could require us to adjust the valuation allowances for
our deferred tax assets and the ultimate realization of tax assets depends on the generation of sufficient taxable income.

On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs
Act (“Tax Act”).  The Tax Act makes broad and complex changes to the U.S. tax code including, but not limited to (1) reducing the U.S.
federal corporate tax rate from 35% to 21%, (2) eliminating the corporate alternative minimum tax (AMT) and changing how existing
AMT credits can be realized, (3) creating a new limitation on deductible interest expense, (4) changes to bonus depreciation, and (5)
changing rules related to use and limitations of net operating loss carryforwards for tax years beginning after December 31, 2017.  The only
material items that impacted the Company’s consolidated financial statements in 2017 were bonus depreciation and the corporate rate
reduction.  While the corporate rate reduction is effective January 1, 2018, we accounted for this anticipated rate change during the year
ended December 31, 2017, the year of enactment.  Consequently, we recorded a $3.4 million decrease to the net deferred tax liability, with
a corresponding net adjustment to deferred tax benefit in our consolidated financial statements for the year ended December 31, 2017.

Our methodology for recording income taxes requires a significant amount of judgment in the use of assumptions and estimates.

Additionally, we forecast certain tax elements, such as future taxable income, as well as

45

evaluate the feasibility of implementing tax planning strategies. Given the inherent uncertainty involved with the use of such variables,
there can be significant variation between anticipated and actual results. Unforeseen events may significantly impact these variables, and
changes to these variables could have a material impact on our income tax accounts. The final determination of our income tax liabilities
involves the interpretation of local tax laws and related authorities in each jurisdiction. Changes in the operating environments, including
changes in tax law, could impact the determination of our income tax liabilities for a tax year.

46

Item 7A. Quantitative and Qualitative Disclosure of Market Risks

Market risk is the risk of loss arising from adverse changes in market rates and prices. Historically, our risks have been predominantly
related to potential changes in the fair value of our long‑term debt due to fluctuations in applicable market interest rates. Going forward our
market risk exposure generally will be limited to those risks that arise in the normal course of business, as we do not engage in speculative,
non‑operating transactions, nor do we utilize financial instruments or derivative instruments for trading purposes.

Commodity Price Risk

Our material and fuel purchases expose us to commodity price risk. Our material costs primarily include the cost of inventory

consumed while performing our pressure pumping services such as proppants, chemicals, guar, trucking and fluid supplies. Our fuel costs
consist primarily of diesel fuel used by our various trucks and other motorized equipment. The prices for fuel and the raw materials in our
inventory are volatile and are impacted by changes in supply and demand, as well as market uncertainty and regional shortages.
Historically, we have generally been able to pass along price increases to our customers; however, we may be unable to do so in the future.
We do not engage in commodity price hedging activities.

Interest Rate Risk

We may be subject to interest rate risk on variable rate debt under our credit facility. The impact of a 1% increase in interest rates on
our variable rate debt as of December 31, 2018, 2017 and 2016 would have resulted in an increase in interest expense and corresponding
decrease in pre‑tax income of approximately $0.7 million, $0.2 million and $2.1 million, for the years ended December 31, 2018, 2017 and
2016, respectively.

Credit Risk

Financial instruments that potentially subject us to concentrations of credit risk are trade receivables. We extend credit to customers
and other parties in the normal course of business. We have established various procedures to manage our credit exposure, including credit
evaluations and maintaining an allowance for doubtful accounts.

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

The management of ProPetro Holding Corp. is responsible for establishing and maintaining adequate internal control over financial

reporting for the Company. ProPetro Holding Corp. maintains a system of internal accounting controls designed to provide reasonable
assurance, at a reasonable cost, that assets are safeguarded against loss or unauthorized use and that the financial records are adequate and
can be relied upon to produce financial statements in accordance with accounting principles generally accepted in the United States of
America. The internal control system is augmented by written policies and procedures, an internal audit program and the selection and
training of qualified personnel. This system includes policies that require adherence to ethical business standards and compliance with all
applicable laws and regulations.

There are inherent limitations to the effectiveness of any controls system. A controls system, no matter how well designed and
operated, can provide only reasonable, not absolute, assurance that the objectives of the controls system are met. Also, no evaluation of
controls can provide absolute assurance that all control issues and any instances of fraud, if any, within the Company will be detected.
Further, the design of a controls system must reflect the fact that there are resource constraints, and the benefits of controls must be
considered relative to their costs. The Company intends to continually improve and refine its internal controls.

Under the supervision and with the participation of our management, including our principal executive officer and principal financial
officer, we conducted an evaluation of the effectiveness of the design and operations of our internal control over financial reporting as of
December 31, 2018 based on criteria established in the 2013 Internal Control—Integrated Framework issued by the Committee of
Sponsoring Organizations of the Treadway Commission (COSO). Based on this evaluation, management’s assessment is that ProPetro
Holding Corp. maintained effective internal control over financial reporting as of December 31, 2018. The independent registered public
accounting firm, Deloitte & Touche LLP, has audited the consolidated financial statements as of and for the year ended December 31,
2018, and has also issued their report on the effectiveness of the Company’s internal control over financial reporting, included in this report
on page 50.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the shareholders and the Board of Directors of
ProPetro Holding Corp. and Subsidiary

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of ProPetro Holding Corp. and Subsidiary (the "Company") as of
December 31, 2018 and 2017, the related consolidated statements of income, shareholders' equity and cash flows, for each of the three
years in the period ended December 31, 2018, and the related notes (collectively referred to as the "financial statements"). In our opinion,
the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2018 and 2017,
and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2018, in conformity with,
accounting principles generally accepted in the United States of America.

We have also 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 and our report dated
February 28, 2019, expressed an unqualified opinion on the Company's internal control over financial reporting.

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.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the shareholders and the Board of Directors of
ProPetro Holding Corp. and Subsidiary

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of ProPetro Holding Corp. and Subsidiary (the “Company”) 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 have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB),

the consolidated financial statements as of and for the year ended December 31, 2018, of the Company and our report dated February 28,
2019, expressed an unqualified opinion on those financial statements.

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 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 included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists,
testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and 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.

DECEMBER 31, 2018, 2017 AND 2016

1. ORGANIZATION AND HISTORY

ProPetro Holding Corp. (“Holding”), a Texas corporation was formed on April 14, 2007, to serve as a holding company for its wholly
owned subsidiary ProPetro Services, Inc. (“Services”), a Texas corporation. Services provides hydraulic fracturing (inclusive of acidizing),
cementing, coil tubing, drilling and flowback services to oil and gas producers, located primarily in Texas, Oklahoma, New Mexico, Utah,
Colorado, and Wyoming. Holding was converted and incorporated to a Delaware Corporation on March 8, 2017.

Holding and Services are collectively referred to as the “Company” in the accompanying consolidated financial statements.

On December 22, 2016, the Company restated and amended the Company’s Shareholders Agreement and certificate of formation in the

state of Texas, approving a reverse stock split, such that each holder of common stock of the Company shall receive one share of common
stock for every 170.4667 shares of previous common stock held. In conjunction, the Company amended the amount of authorized shares to
230,000,000, of which 200,000,000 are common and 30,000,000 are preferred.

On March 22, 2017, we consummated our initial public offering (“IPO”) in which 25,000,000 shares of our common stock, par value

$0.001 per share, were sold at a public offering price of $14.00 per share, with 13,250,000 shares issued and sold by the Company and
11,750,000 shares sold by existing stockholders. We received net proceeds of approximately  $170.1 million after deducting $10.9 million
of underwriting discounts and commissions, and $4.5 million of other offering expenses. At closing, we used the proceeds (i) to repay
$71.8 million in outstanding borrowings under the term loan, (ii) $86.8 million to fund the purchase of additional hydraulic fracturing units
and other equipment, and (iii) the remaining for general corporate purposes.

In connection with the IPO, the Company executed a stock split, such that each holder of common stock of the Company received  1.45

shares of common stock for every one share of previous common stock, and all 16,999,990 shares of our outstanding Series A preferred
stock converted to common stock on a 1:1 basis.

Accordingly, any information related to or dependent upon the share or option counts in the 2018, 2017 and 2016 consolidated

financial statements and Note 13 Net Income (loss) Per Share, Note 14 Stock‑Based Compensation, Note 18 Equity Capitalization and Note
19 Quarterly Financial Data (Unaudited) have been updated to reflect the effect of the reverse stock split in December 2016 and the stock
split in March 2017, as applicable.

On December 31, 2018, we consummated the purchase of pressure pumping and related assets of Pioneer and Pioneer Pumping

Services. The pressure pumping assets acquired were used to provide integrated well completion services in the Permian Basin to Pioneer’s
completion and production operations. The acquisition cost of the assets was comprised of $110.0 million of cash and 16.6 million shares
of our common stock. The incremental direct cost of $3.4 million incurred to consummate the transaction was capitalized as part of the
acquisition cost. In connection with the acquisition, we became a long-term service provider to Pioneer, providing pressure pumping and
related services for a term of up to 10 years. The pressure pumping assets acquired include eight hydraulic fracturing fleets with 510,000
HHP, four coiled tubing units and the associated equipment maintenance facility. We evaluated and determined that the acquisition did not
meet the definition of a Business under GAAP because substantially all of the assets acquired are concentrated in a group of similar assets.
Accordingly, we have accounted for the acquisition as an asset purchase.

2. SIGNIFICANT ACCOUNTING POLICIES

A summary of the significant accounting policies consistently applied in the preparation of the accompanying consolidated financial

statements are as follows:

Principles of Consolidation — The accompanying consolidated financial statements include the accounts of Holding and its wholly

owned subsidiary, Services. All intercompany accounts and transactions have been eliminated in consolidation.

Basis of Presentation — The accompanying consolidated financial statements and related notes have been prepared pursuant to the
rules and regulations of the Securities Exchange Commission (“SEC”) and in conformity with accounting principles generally accepted in
the United States of America (“GAAP”).

Use of Estimates — Management is required to make estimates and assumptions that affect the reported amounts of assets and
liabilities and the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and revenues and
expenses during the reporting period. Such estimates include, but are not limited to, allowance for doubtful accounts, depreciation of
property and equipment, estimates of fair value of property and equipment, estimates related to fair value of reporting units for purposes of
assessing goodwill, estimates related to deferred tax assets and liabilities, including any related valuation allowances, and estimates of fair
value of stock‑based compensation. Actual results could differ from those estimates.

Revenue Recognition — The Company’s services are sold based upon contracts with customers. The Company recognizes revenue
when it satisfies a performance obligation by transferring control over a product or service to a customer. The following is a description of
the principal activities, separated by reportable segment and all other, from which the Company generates its revenue.

Pressure Pumping — Pressure pumping consists of downhole pumping services, which includes hydraulic fracturing (inclusive of

acidizing services) and cementing.

Hydraulic fracturing is a well-stimulation technique intended to optimize hydrocarbon flow paths during the completion phase of
shale wellbores. The process involves the injection of water, sand and chemicals under high pressure into shale formations. Hydraulic
fracturing contracts with our customer have one performance obligation, which is the contracted total stages, satisfied over time. We
recognize revenue over time using a progress output method, unit-of-work performed method, which is based on the agreed fixed
transaction price and actual stages completed. We believe that recognizing revenue based on actual stages completed faithfully depicts
how our hydraulic fracturing services are transferred to our customers over time.

Acidizing, which is part of our hydraulic fracturing operating segment, involves a well-stimulation technique where acid is injected

under pressure into formations to form or expand fissures. Acidizing provides downhole solutions, and contracts with customers have
one performance obligation, which is satisfied at a point-in-time upon completion of the contracted service when control is transferred
to the customer. Jobs for these services are typically short term in nature, with most jobs completed in less than a day. We recognize
acidizing revenue at a point-in-time, upon completion of the performance obligation.

Our cementing services use pressure pumping equipment to deliver a slurry of liquid cement that is pumped down a well between

the casing and the borehole. Cementing involves well bonding solutions, and contracts with customers have one performance
obligation, which is satisfied at a point-in-time upon completion of the contracted service when control is transferred to the customer.
Jobs for these services are typically short term in nature, with most jobs completed in less than a day. We recognize cementing revenue
at a point-in-time, upon completion of the performance obligation. The transaction price for each performance obligation for all our
pressure pumping services are fixed per our contract with customer.

All Other— All other services consist of our surface drilling, drilling, coil tubing and flowback, which are downhole well stimulation

and completion/remedial services. The performance obligation for each of the services

2. SIGNIFICANT ACCOUNTING POLICIES (Continued)

has a fixed transaction price which is satisfied at a point-in-time upon completion of the service when control is transferred to the customer.
Accordingly, we recognize revenue at a point-in-time, upon completion of the service and transfer of control to the customer.

Accounts Receivable — Accounts receivables are stated at the amount billed and billable to customers. Payment is typically due in full

upon completion of the job for all of our services to customers. At December 31, 2018 and 2017 accrued revenue (unbilled receivable)
included as part of our accounts receivable was $18.0 million and $24.8 million, respectively. At December 31, 2018, the transaction price
allocated to the remaining performance obligation for our partially completed hydraulic fracturing operations was $43.9 million, which is
expected to be completed and recognized in one month following the current period balance sheet date, in our pressure pumping reportable
segment. At December 31, 2017 the transaction price allocated to the remaining performance obligation for our then partially completed
hydraulic fracturing operations was $26.4 million, which was recorded as part of our pressure pumping segment revenue for the year ended
December 31, 2018.

At December 31, 2018, 2017 and 2016, the allowance for doubtful accounts was  $0.1 million, $0.4 million and $0.6 million,

respectively. During the year, additional allowance for doubtful accounts was $0.1 million and the allowance no longer required was  0.4
million.

Inventories — Inventories, which consists only of raw materials, are stated at lower of average cost and net realizable value.

Property and Equipment — The Company’s property and equipment are recorded at cost, less accumulated depreciation.

Depreciation — Depreciation of property and equipment is provided on the straight‑line method over the following estimated useful

lives:

Land
Buildings and property improvements
Vehicles
Equipment
Leasehold improvements

Indefinite
5 - 30 years
1 ‑ 5 years
1 ‑ 20 years
5 ‑ 20 years

Upon sale or retirement of property and equipment, the cost and related accumulated depreciation are removed from the balance sheet

and the net amount, less proceeds from disposal, is recognized as a gain or loss in the statement of operations. The Company recorded a
loss on disposal of assets of $59.2 million, $39.1 million and $22.5 million for the years ended December 31, 2018, 2017 and 2016,
respectively.

Impairment of Long‑Lived Assets — In accordance with Financial Accounting Standards Board (FASB) Accounting Standards

Codification (ASC) 360, Accounting for the Impairment or Disposal of Long‑Lived Assets, the Company reviews its long‑lived assets to be
held and used whenever events or circumstances indicate that the carrying value of those assets may not be recoverable.

An impairment loss is indicated if the sum of the expected future undiscounted cash flows attributable to the asset group is less than
the carrying amount of such asset group. In this circumstance, the Company recognizes an impairment loss for the amount by which the
carrying amount of the asset group exceeds the fair value of the asset group. No impairment was recorded in the years ended December 31,
2018 and 2017. The impairment recorded in 2016 was $6.3 million for property and equipment relating to the drilling asset group.

DECEMBER 31, 2018, 2017 AND 2016

2. SIGNIFICANT ACCOUNTING POLICIES (Continued)

The Company accounts for long‑lived assets to be disposed of at the lower of their carrying amount or fair value, less cost to sell once

management has committed to a plan to dispose of the assets.

Goodwill — Goodwill is the excess of the consideration transferred over the fair value of the tangible and identifiable intangible assets

and liabilities recognized. Goodwill is not amortized. We perform an annual impairment test of goodwill as of December 31, or more
frequently if circumstances indicate that impairment may exist. The determination of impairment is made by comparing the carrying
amount of a reporting unit with its fair value, which is generally calculated using a combination of market and income approaches. If the
fair value of the reporting unit exceeds the carrying value, no further testing is performed. If the fair value of the reporting unit is less than
the carrying value, we consider goodwill to be impaired, and the amount of impairment loss is estimated and recorded in the statement of
operations.

In 2014, we acquired Blackrock Drilling, Inc. (“Blackrock”) for $1.8 million. The assets acquired from Blackrock were recorded as
$0.6 million of equipment with the excess of the purchase price over the fair value of the assets recorded as goodwill of  $1.2 million. The
acquisition complemented our existing drilling operations. The transaction has been accounted for using the acquisition method of
accounting and, accordingly, assets and liabilities assumed were recorded at their fair values as of the acquisition date. Based on our
goodwill impairment test as of December 31, 2016, the Company concluded that there was an impairment of goodwill of $1.2 million
related to the Blackrock acquisition. Accordingly, a $1.2 million impairment expense was recorded during the year ended December 31,
2016, to fully write-down the goodwill related to Blackrock. Prior to the impairment write‑down, the goodwill related to the Blackrock
acquisition of $1.2 million was recorded in our all other reportable segment.

In 2011, we acquired Technology Stimulation Services, LLC (“TSS”) for $24.4 million. The assets acquired from TSS were recorded
as $15.0 million of equipment with the excess of the purchase price over fair value of the assets recorded as goodwill of  $9.4 million. The
acquisition complemented our existing pressure pumping business. The transaction has been accounted for using the acquisition method of
accounting and, accordingly, assets and liabilities assumed were recorded at their fair values as of the acquisition date. Based on our
goodwill impairment tests as of December 31, 2018, 2017 and 2016, we concluded that the goodwill related to TSS acquisition was  not
impaired. The goodwill related to the TSS acquisition of $9.4 million is recorded in our pressure pumping reportable segment.

Intangible Assets — Intangible assets with finite useful lives are amortized on a basis that reflects the pattern in which the economic

benefits of the intangible assets are realized, which is generally on a straight‑line basis over the asset’s estimated useful life.

Income Taxes — Income taxes are accounted for under the asset and liability method, which requires the recognition of deferred tax
assets and liabilities for the expected future tax consequences of events that have been included in the consolidated financial statements.
Under this method, deferred tax assets and liabilities are determined on the basis of differences between the consolidated financial
statements and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to
reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the
enactment date.

We recognize deferred tax assets to the extent that we believe these assets are more likely than not to be realized. In making such a

determination, we consider all positive and negative evidences, including future reversals of existing taxable temporary differences,
projected future taxable income, and the results of recent operations. If we determine that we would be able to realize our deferred tax
assets in the future in excess of their net recorded amount, we would make an adjustment to the deferred tax asset valuation allowance,
which would reduce the provision for income taxes.

Advertising Expense — All advertising costs are expensed as incurred. For the years ended  December 31, 2018, 2017 and 2016,

advertising expense was $1.3 million, $0.8 million and $0.4 million, respectively.

DECEMBER 31, 2018, 2017 AND 2016

2. SIGNIFICANT ACCOUNTING POLICIES (Continued)

Deferred Loan Costs — The Company capitalized certain costs in connection with obtaining its borrowings, including lender, legal,
and accounting fees. These costs are being amortized over the term of the related loan using the straight‑line method. Deferred loan costs
amortization is included in interest expense. Unamortized deferred loan costs associated with loans paid off or refinanced with different
lenders are expensed in the period in which such an event occurs. Deferred loan costs are classified as a reduction of long‑term debt or in
certain instance as an asset in the consolidated balance sheet. Amortization of deferred loan costs is recorded as interest expense in the
statement of operations, and during the years ended December 31, 2018, 2017 and 2016, the amount of expense recorded was  $0.4 million,
$3.4 million and $2.1 million, respectively.

Stock-Based Compensation — The Company recognizes the cost of stock‑based awards on a straight‑line basis over the requisite
service period of the award, which is usually the vesting period under the fair value method. Total compensation cost is measured on the
grant date using fair value estimates.

Insurance Financing — The Company annually renews its commercial insurance policies and records a prepaid insurance asset and
amortizes it monthly over the coverage period. The Company may choose to finance a portion of the premiums and will make repayments
monthly over ten months in equal installments.

Concentration of Credit Risk — The Company’s assets that are potentially subject to concentrations of credit risk are cash and cash
equivalents and trade accounts receivable. Cash balances are maintained in financial institutions, which at times exceed federally insured
limits. The Company monitors the financial condition of the financial institutions in which accounts are maintained and has not experienced
any losses in such accounts. The receivables of the Company are spread over a number of customers, a majority of which are credible
operators and suppliers to the oil and natural gas industries. The Company performs ongoing credit evaluations as to the financial condition
of its customers with respect to trade receivables.

Recently Issued Accounting Standards Adopted in 2018

In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09,

Revenue from Contracts with Customers (Topic 606). ASU No. 2014-09 requires entities to recognize revenue to depict transfer of
promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange
for those goods or services. ASU No. 2014-09 requires entities to disclose both qualitative and quantitative information that enables users
of the consolidated financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from
contracts with customers, including disclosure of significant judgments affecting the recognition of revenue. ASU No. 2014-09 was
effective for annual periods beginning after December 15, 2017, using either the full retrospective or modified retrospective method. We
adopted ASU No. 2014-09 effective January 1, 2018, using the modified retrospective method. The adoption of this guidance had no
impact on our prior period results of operations. This is because prior to the effective date of the new revenue guidance, substantially all of
our performance obligations per our contracts with customers, except for hydraulic fracturing, were completed at a point-in-time, and
revenue recognized when control was transferred to the customers, which is consistent with ASU No. 2014-09. Our hydraulic fracturing
segment performance obligation is satisfied over time. Prior to the effective date of the new revenue standards, our hydraulic fracturing
segment revenue was recognized based on actual stages completed, i.e. using the output method, which faithfully depicts how our services
are transferred over time to our customers and is consistent with the requirements of the new guidance, ASU No. 2014-09. Accordingly, no
adjustments to our consolidated financial statements were required, other than the additional disclosures included as part of Note 2 in our
consolidated financial statements.

Recently Issued Accounting Standards Not Yet Adopted in 2018

In February 2016, the FASB issued ASU No. 2016-02, Leases. This ASU introduces a lessee model that brings most leases on the
balance sheet. This new standard increases transparency and comparability by recognizing a lessee’s rights and obligations resulting from
leases by recording them on the balance sheet as Right of Use ("ROU") Assets and Lease Liabilities. Leases will be classified as either
finance or operating, which will impact the pattern of

59

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS AS OF AND FOR THE YEARS ENDED
DECEMBER 31, 2018, 2017 AND 2016

2. SIGNIFICANT ACCOUNTING POLICIES (Continued)

expense recognition on the income statement. This ASU also requires additional qualitative and quantitative disclosures to better enable
users of financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. This ASU is effective for
annual reporting periods beginning after December 15, 2018. Early adoption is permitted. We adopted this new lease standard effective
January 1, 2019 and intend to elect the modified retrospective transition method. As such, the comparative financial information will not be
restated and will continue to be reported under the lease standard in effect during those periods. We also intend to elect other practical
expedients provided by the new standard, including the package of practical expedients, the short-term lease recognition practical expedient
in which leases with a term of 12 months or less will not be recognized on the balance sheet, and the practical expedient to not separate
lease and non-lease components for the majority of our leases. We believe that the adoption of this standard will result in an amount no
greater than $10.0 million of additional assets and liabilities on our consolidated balance sheet representing the recognition of operating
lease right-of-use assets and operating lease liabilities.

In January 2017, the FASB issued ASU No. 2017-04, Simplifying the Test for Goodwill Impairment , which removes the requirement to

compare the implied fair value of goodwill with its carrying amount as part of step two of the goodwill impairment test. As a result, under
this ASU, an entity would recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair
value. Although, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. This ASU is effective
for impairment tests in fiscal years beginning after December 15, 2019, on a prospective basis. Early adoption is permitted for interim or
annual goodwill impairment tests performed on testing dates after January 1, 2017. We believe that the adoption of this guidance will not
materially affect our consolidated financial statements.

4. FAIR VALUE MEASUREMENTS

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e., the “exit price”) in an orderly

transaction between market participants at the measurement date.

In determining fair value, the Company uses various valuation approaches and establishes a hierarchy for inputs used in measuring fair

value that maximizes the use of relevant observable inputs and minimizes the use of unobservable inputs by requiring that the most
observable inputs be used, when available. Observable inputs are inputs that market participants would use in pricing the asset or liability
developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the
Company’s assumptions about the assumptions other market participants would use in pricing the asset or liability developed based on the
best information available in the circumstances. The hierarchy is broken down into three levels based on the observability of inputs as
follows:

Level 1 — Valuations based on quoted prices in active markets for identical assets or liabilities that the Company has the ability to
access. Valuation adjustments and block discounts are not applied to Level 1 instruments. Since valuations are based on quoted prices that
are readily and regularly available in an active market, valuation of these instruments does not entail a significant degree of judgment.

Level 2 — Valuations based on one or more quoted prices in markets that are not active or for which all significant inputs are

observable, either directly or indirectly.

Level 3 — Valuations based on inputs that are unobservable and significant to the overall fair value measurement.

A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the
fair value measurement. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety
requires judgment and considers factors specific to the asset or liability.

Assets and Liabilities Measured at Fair Value on a Recurring Basis

Our financial instruments include cash and cash equivalents, accounts receivable and accounts payable, accrued liabilities and long-
term debt. The estimated fair value of our financial instruments — cash and cash equivalent, accounts receivable and accounts payable and
accrued liabilities at December 31, 2018 and 2017 approximates their

4. FAIR VALUE MEASUREMENTS (Continued)

carrying value as reflected in our consolidated balance sheets because of their short‑term nature. In 2018, we did not have a derivate
financial instrument. Prior to 2018, we used a derivative financial instrument, an interest rate swap, to manage interest rate risk. Our policies
do not permit the use of derivative financial instruments for speculative purposes. We did not designate the interest rate swap as a hedge for
accounting purposes. We record all derivatives as of the end of our reporting period in our consolidated balance sheet at fair value, which
is based on quoted market prices, which represents a level 1 in the fair value measurement hierarchy. Based on quoted market prices as of
December 31, 2017 and 2016, for contracts with similar terms and maturity date, as provided by the counterparty, we recorded a gain of
$0.3 million and $0.2 million, respectively, in our consolidated statement of operations. The fair value of the interest rate swap liability at
December 31, 2017 and 2016 was $0 and $0.3 million, respectively.

Assets Measured at Fair Value on a Nonrecurring Basis

No assets were measured at fair value on a nonrecurring basis at  December 31, 2018 and 2017, respectively.

No impairment was recorded for our property and equipment during the year ended  December 31, 2018 and 2017. In 2016, the
depressed cash flows and continued decline in utilization of our drilling assets were indicative of potential impairment, resulting in the
Company comparing the carrying value of the drilling assets with its estimated fair value. We determined that the carrying value of the
drilling assets was greater than its estimated fair value and accordingly, an impairment expense was recorded. In 2016, the non‑cash asset
impairment charges for drilling was $6.3 million, which had a net carrying value of $15.0 million prior to the impairment write‑down. See
Note 7, “Impairment of Long‑Lived Assets.”

We generally apply fair value techniques to our reporting units on a nonrecurring basis associated with valuing potential impairment
loss related to goodwill. Our estimate of the reporting unit fair value is based on a combination of income and market approaches, Level 1
and 3, respectively, in the fair value hierarchy. The income approach involves the use of a discounted cash flow method, with the cash flow
projections discounted at an appropriate discount rate. The market approach involves the use of comparable public companies market
multiples in estimating the fair value. Significant assumptions include projected revenue growth, capital expenditures, utilization, gross
margins, discount rates, terminal growth rates, and weight allocation between income and market approaches. If the reporting unit's
carrying amount exceeds its fair value, we consider goodwill impaired, and the impairment loss is recorded in the period. There were no
additions to, or disposal of, goodwill during the year ended December 31, 2018, 2017 and 2016. Based on our annual goodwill impairment
test, no impairment of goodwill was recorded for the year ended  December 31, 2018 and 2017. At December 31, 2016, we estimated the
fair value of our surface air drilling reporting unit to be $3.8 million and its carrying value was $4.2 million. As a result of the potential
impairment with the carrying value exceeding the estimated fair value, we then further determined the implied fair value of the surface
drilling goodwill to be $0. Accordingly, we recorded an impairment expense of $1.2 million. The impairment expense was attributable to
the challenging oil and gas market and slow recovery of crude oil prices, all of which adversely impacted on our expected future cash flows
for the surface air drilling reporting unit.

5. INTANGIBLE ASSETS

Intangible assets are composed of internally developed software. Intangible assets are amortized on a straight‑line basis with a useful

life of five years. Amortization expense included in net income (loss) for the years ended December 31, 2018, 2017 and 2016 was $0.3
million, $0.3 million and $0.3 million, respectively. At December 31, 2018 and 2017, respectively, the company’s intangible assets subject
to amortization are as follows:

7. IMPAIRMENT OF LONG‑LIVED ASSETS

Whenever events or circumstances indicate that the carrying value of long‑lived assets may not be recoverable, the Company reviews

the carrying value of long‑lived assets, such as property and equipment and other assets to determine if they are recoverable. If any
long‑lived assets are determined to be unrecoverable, an impairment expense is recorded in the period. Asset recoverability is estimated
using undiscounted future net cash flows at the lowest identifiable level, excluding interest expense and one‑time other income and expense
adjustments. During the year, the Company determined the lowest level of identifiable cash flows to be at the asset group level, which
consists of hydraulic fracturing (inclusive of acidizing), cementing, coil tubing, flowback and drilling.

During the year ended December 31, 2018 and 2017, no impairment expense was recorded for any of our asset groups. During the year

ended December 31, 2016, the gradual shift from vertical to horizontal drilling rigs in the Permian Basin led to the deterioration in
utilization of our drilling rigs, and we expected undiscounted future cash flows to be lower than the carrying value of the drilling assets.
Given that the carrying value of the drilling assets may not be recoverable, the Company estimated the fair value of the asset group and
compared it to its carrying value. Potential impairment exists if the estimated undiscounted future net cash flows for a given asset group is
less than the carrying amount of the asset group. The impairment expense is determined by comparing the estimated fair value with the
carrying value of the related asset, and any excess amount by which the carrying value exceeds the fair value is recorded as an impairment
expense in the period. At December 31, 2016, the estimated fair value of the drilling asset group of $8.7 million was determined using the
market approach, which represents a level 2 in the fair value measurement hierarchy. Our fair value estimates required us to use significant
other observable inputs including assumptions related to replacement cost, among others. Accordingly, an impairment expense of $6.3

million was recorded in 2016 as the carrying value of the drilling asset group of $15.0 million was greater than its then estimated fair value.
All other assets group carrying values were determined to be recoverable in 2016.

8. DEFERRED REVENUE REBATE

In November 2011, the Company acquired certain oilfield fracturing equipment from a customer and agreed to provide future
fracturing services to the customer for a period of 78 months in exchange for a 12% $25.0 million note payable to the customer. The
Company recorded the fracturing equipment at its estimated fair value of approximately $13.0 million and assigned the remaining value of
approximately $12.0 million to a deferred revenue rebate account to be amortized over the customer’s 78‑month service period. In March
2013, the Company repaid the note payable to the customer. For each of the years ended December 31, 2018, 2017 and 2016 the Company
recorded $0.6 million, $1.8 million and $1.8 million, respectively, of amortization rebate as a reduction of revenue.

9. LONG‑TERM DEBT

2013 Term Loan and Revolving Credit Facility

On September 30, 2013, we entered into a term loan in the amount of $220 million ("Term Loan") with a $40 million revolving credit
line ("Revolving Credit Facility"). Borrowings under the Term Loan and Revolving Credit Facility accrued interest at LIBOR plus 6.25%,
subject to a 1% LIBOR floor, and were secured by a first priority lien and security interest in all assets of the Company. The Term Loan and
Revolving Credit Facility were scheduled to mature on September 30, 2019 and September 30, 2018, respectively, with quarterly and
monthly payments of principal and interest, respectively.

Under the Term Loan and Revolving Credit Facility we were required to comply, subject to certain exceptions and materiality
qualifiers, with certain customary affirmative and negative covenants, including, but not limited to, covenants pertaining to reporting,
insurance, collateral maintenance, change of control, transactions with affiliates, distributions, and limitations on additional indebtedness.
In addition, the Term Loan and Revolving Credit Facility included a maximum leverage ratio of 3.5x EBITDA (earnings before interest,
taxes, depreciation, and amortization) to total debt, which became effective March 31, 2014.

In 2015, given the then near-term economic uncertainty and volatility of commodity prices, we determined that we were likely to be

out of compliance with the leverage ratio covenant under the Term Loan and Revolving Credit Facility at the March 31, 2016 test date.
Accordingly, the Company and its then equity sponsor, Energy Capital Partners ("ECP"), commenced negotiations with the lenders to
amend the covenants and leverage ratio in the Term Loan and Revolving Credit Facility. The resulting amendment and waiver agreement
was executed on June 8, 2016. Under the terms of the amendment, ECP infused $40.0 million of additional equity into the Company, $10.0
million of which was reserved for working capital, with up to $30.0 million available to repurchase debt. A minority shareholder also
infused $0.4 million alongside ECP to prevent dilution. The amendment and waiver also suspended the leverage ratio test until June 30,
2017, and provided us with 30 days to deliver any past-due financial statements.

Gain on Extinguishment of Debt

In connection with the amendment to the Term Loan and Revolving Credit Facility, we initiated an auction process with the lenders to

repurchase a portion of debt for a price of $0.80, a 20% discount to par value. The auction settled on June 16, 2016 as the Company
repurchased a total amount of $37.5 million of debt for $30.0 million plus $0.5 million in debt extinguishment auction costs, leading to a
gain on extinguishment of debt of $7.0 million.

On January 13, 2017, we repaid $75.0 million of the outstanding balance under the Term Loan and repaid the remaining balance of
$13.5 million under the Revolving Credit Facility using a portion of the proceeds from our private placement offering. On March 22, 2017,
we retired the $71.8 million remaining balance of the Term Loan, along with accrued interest, using a portion of the proceeds from our
IPO. Each of the Term Loan and Revolving Credit Facility were terminated in accordance with their terms upon the repayment of
outstanding borrowings.

Equipment Financing

On November 24, 2015, we entered into a 36 months financing arrangement for three hydraulic fracturing units in the amount of $25.0

million, and a portion of the proceeds were used to pay off the previous manufacturer notes, with the remainder being used for additional
liquidity. As of December 31, 2018, we have fully repaid all outstanding balance and met all obligations under this financing arrangement.

On June 30, 2017, we entered into a financing arrangement for the purchase of light vehicles. As of December 31, 2018, we have fully

repaid all outstanding balance and met all obligations under this financing arrangement.

ABL Credit Facility

On March 22, 2017, we entered into a new revolving credit facility with a $150.0 million borrowing capacity ("ABL Credit Facility").
Borrowings under the ABL Credit Facility accrue interest based on a three-tier pricing grid tied to availability, and we may elect for loans
to be based on either LIBOR or base rate, plus the applicable margin, which ranges from 1.75% to 2.25% for LIBOR loans and 0.75% to
1.25% for base rate loans, with no LIBOR floor. Borrowings under the ABL Credit Facility are secured by a first priority lien and security
interest in substantially all assets of the Company. The ABL Credit Facility has a term of 5 years and a borrowing base of 85% of eligible
accounts receivable less customary reserves. Under this facility we are required to comply, subject to certain exceptions and materiality
qualifiers, with certain customary affirmative and negative covenants, including, but not limited to, covenants pertaining to our ability to
incur liens, indebtedness, changes in the nature of our business, mergers and other fundamental changes, disposal of assets, investments
and restricted payments, amendments to our organizational documents or accounting policies, prepayments of certain debt, dividends,
transactions with affiliates, and certain other activities. In addition, the ABL Credit Facility includes a Springing Fixed Charge Coverage
Ratio of 1.0x when excess availability is less than the greater of (i) 10% of the lesser of the facility size and the Borrowing Base and (ii)
$12.0 million. The ABL has a commitment fee of 0.38%, which reduces to 0.25% if utilization is greater than 50% of the borrowing base.

On February 22, 2018, we entered into a first amendment with our lenders to increase the capacity of the ABL Credit Facility. The

amendment increased total capacity under the facility from $150.0 million to $200.0 million. The first amendment to the ABL Credit
Facility modified the Springing Fixed Charge Coverage Ratio to apply when excess availability is less than the greater of (i) 10% of the
lesser of the facility size and the Borrowing Base and (ii) $15 million.

On December 19, 2018, we entered into a second amendment with our lenders to further increase the capacity of the ABL Credit
Facility. The second amendment increased total capacity under the facility from $200.0 million to $300.0 million and extended the maturity
date of the ABL Credit Facility from March 22, 2022 until December 19, 2023. The second amendment to the ABL Credit Facility
modified the Springing Fixed Charge Coverage Ratio to apply when excess availability is less than the greater of (i) 10% of the lesser of
the facility size and the Borrowing Base and (ii) $22.5 million.

The fair values of the ABL Credit Facility and equipment financing approximate their carrying values.

11. EMPLOYEE BENEFIT PLAN

The Company has a 401(k) plan whereby all employees with six months of service may contribute up to $15,000 to the plan annually.

The employees vest in the Company contributions to the 401(k) plan 25% per year, beginning in the employee’s second year of service,
with full vesting occurring after five years of service. The employees are fully vested in their contributions when made. The Company
matches employee contributions 20 cents on the dollar up to 10% of gross salary. During the years ended December 31, 2018, 2017 and
2016, the recorded expense under the plan was  $0.3 million, $0.2 million and $0.2 million, respectively. Effectively January 1, 2019, we
modified our 401(k) plan whereby all employees with sixty days of service may contribute up to $19,000 to the plan annually. The
employees vest in the Company contributions to the 401(k) plan 25% per year, beginning in the employee’s first year of service, with full
vesting occurring after four years of service. The employees are fully vested in their contributions when made. The Company matches
100% of the employee contributions up to 6% of gross salary.

12. REPORTABLE SEGMENT INFORMATION

The Company has five operating segments for which discreet financial information is readily available: hydraulic fracturing (inclusive
of acidizing), cementing, coil tubing, flowback, and drilling. These operating segments represent how the Chief Operating Decision Maker
evaluates performance and allocates resources.

On August 31, 2018, we divested our surface air drilling operations, included in our "all other" category, in order to continue to focus

and position ourselves as a Permian Basin-focused pressure pumping business because we believe the pressure pumping market in the
Permian Basin offers more supportive long-term growth fundamentals. The divestiture of our surface air drilling operations did not qualify
for presentation and disclosure as discontinued operations, and accordingly, we have recorded the resulting loss on disposal of our surface
air drilling of $0.3 million as part of our loss on disposal of asset in our consolidated statement of operations. The divestiture of our surface
air drilling operations resulted in a reduction in the number of our current operating segments to five. The change in the number of our
operating segments did not impact our reportable segment information reported for the years ended December 31, 2018, 2017 and 2016.

In accordance with Accounting Standards Codification 280—Segment Reporting, the Company has one reportable segment (pressure

pumping) comprised of the hydraulic fracturing and cementing operating segments. All other operating segments and corporate
administrative expenses are included in the ‘‘all other’’ category in the table below. Inter-segment revenues are not material and are not
shown separately in the table below.

The Company manages and assesses the performance of the reportable segment by its adjusted EBITDA (earnings before other income

(expense), interest, taxes, depreciation & amortization, stock-based compensation expense, impairment expense, (gain)/loss on disposal of
assets and other unusual or nonrecurring expenses or income). A reconciliation from segment level financial information to the
consolidated statement of operations is provided in the table below.

13. NET INCOME (LOSS) PER SHARE

Basic net income (loss) per common share is computed by dividing the net income (loss) relevant to the common stockholders by the

weighted-average number of shares outstanding during the year. Diluted net income (loss) per common share uses the same net income
(loss) divided by the sum of the weighted-average number of shares of common stock outstanding during the period, plus  dilutive effects of
options, performance and restricted stocks units outstanding during the period calculated using the treasury method and the potential
dilutive effects of preferred stocks (if any) calculated using the if-converted method. The table below shows the calculations for years

Effective March 4, 2013, we adopted the ProPetro Stock Option Plan pursuant to which our Board of Directors may grant stock options

or other stock-based awards to key employees, consultants, and directors. The Plan, as amended, is authorized to grant up to 4,645,884
shares of common stock to be issued upon exercise of the options. The Company’s share price used to estimate the fair value of the option
at the grant date was based on a combination of income and market approaches, which are highly complex and sensitive. The income
approach involves the use of a discounted cash flow method, with cash flow projections discounted at an appropriate discount rate. The
market approach involves the use of comparable public companies market multiples in estimating the fair value of the Company’s stock.
The expected term used to calculate the fair value of all options considers the vesting date and the grant’s expiration date. The expected
volatility was estimated by considering comparable public companies, and the risk free rate is based on the U.S treasury yield curve as of
the grant date. The dividend assumption is based on historical experience. After becoming a public company, the market price was used to
determine the market value of our common stock. Prior to 2015, the Company had granted a total of 3,499,228 options with an exercise
price of $3.96 per option, and all options expire 10 years from the date of grant.

On June 14, 2013, we granted 2,799,408 stock option awards to certain key employees and directors that shall vest and become
exercisable based upon the achievement of a service requirement. The options vest in 25% increments for each year of continuous service
and an option becomes fully vested upon the optionee’s completion of the fourth year of service. The contractual term for the options
awarded is 10 years. The fair value of each option award granted is estimated on the date of grant using the Black-Scholes option-pricing
model. The fair value of the options was estimated at the date of grant using the following assumptions:

On December 1, 2013, we granted 699,820 stock option awards to certain key employees which were scheduled to vest in four
substantially equal annual installments, subject to service and performance requirements and acceleration upon a change in control. As of
December 31, 2016 and 2015 the performance requirements were not considered to be probable of achievement for any of the outstanding
option awards and 114,456 options were forfeited during the year ended December 31, 2016. Effective March 16, 2017, we terminated the
options in connection with our IPO and approved a cash bonus totaling $5.1 million to the holders of the options.

The contractual term for the options awarded is 10 years. The fair value of each option award granted is estimated on the date of grant

using the Black-Scholes option-pricing model. The fair value of the options was estimated at the date of grant using the following

 In March 2017, our shareholders approved the ProPetro 2017 Incentive Award Plan ("IAP") pursuant to which our Board of Directors
may grant stock options, restricted stock units ("RSUs"), performance stock units ("PSUs"), or other stock-based awards to key employees,
consultants, directors and employees. The IAP authorizes up to 5,800,000 shares of common stock to be issued under awards granted
pursuant to the plan. On March 16, 2017, we granted 793,738 stock option awards to certain key employees and directors pursuant to the
IAP which are scheduled to vest in four substantially equal annual installments, subject to a continuing service requirement. The contractual
term for the options awarded is 10 years.

The fair value of each stock option award granted is estimated on the date of grant using the Black- Scholes option-pricing model. The

The weighted average grant-date fair value of stock options granted during the years ended December 31, 2018, 2017 and 2016 was $0,

$3.35 and $1.77, respectively. As of December 31, 2018, the aggregate intrinsic value for our outstanding stock options was $34.0 million,
and the aggregate intrinsic value for our exercisable stock options was $34.0 million. The aggregate intrinsic value for the exercised stock
options during the year was $0.7 million. The remaining contractual term for the outstanding and exercisable stock options as of
December 31, 2018, were 5.9 years and 5.6 years, respectively. For the years ended December 31, 2018, 2017 and 2016, the Company
recognized $0.6 million, $2.9 million and $1.6 million, respectively, in compensation expense related to all stock options.

Restricted Stock Units (Non-Vested Stock) and Performance Stock Units

On September 30, 2013, our Board of Directors authorized and granted 372,335 restricted stock units (RSUs) to a key executive. Each

RSU represents the right to receive one share of common stock of the Company at par value $0.001 per share. Under the terms of the
award, the shares of common stock subject to the RSUs were to be paid to the grantee upon change in control, regardless of whether the
grantee was affiliated with the Company on the settlement date. The fair value of the RSUs is measured as the price of the Company’s
shares on the grant date, which was estimated to be $3.89. The share price used to estimate the fair value of the RSU at the grant date was
based on a combination of income and market approaches, which are highly complex and sensitive. The income approach involves the use
of a discounted cash flow method, with the cash flow projections discounted at an appropriate discount rate. The market approach involves
the use of comparable public companies market multiples in estimating the fair value of the Company’s stock. Effective March 22, 2017,
the Board of Directors canceled these RSUs and issued 372,335 new RSUs to the grantee. These issued RSUs are effectively identical to
the RSUs granted in 2013, provided, however, that the RSUs was payable in full on March 22, 2018. The fair value of the RSUs issued on
March 22, 2017, was based on the Company's closing stock market price at the grant date. In connection with the IPO, we fully recognized
the stock compensation expense related to the re-issued RSUs.

In 2018, our Board of Directors granted 319,250 RSUs to employees, directors and executives pursuant to the Incentive Award Plan

("IAP"). Each RSU represents the right to receive one share of common stock. The fair value of the RSUs is based on the closing share
price of our common stock on the date of grant. For the years ended December 31, 2018, 2017 and 2016 the recorded stock compensation
expense for all RSUs was $2.9 million, $6.2 million and $0, respectively. As of December 31, 2018, the total unrecognized compensation
expense for all RSUs was approximately $5.7 million, and is expected to be recognized over a weighted-average period of approximately
1.6 years.

Effective June 5, 2017, our Board of Directors authorized and granted performance stock unit awards to certain key employees under

the IAP. The actual number of shares that may be issued under the performance stock unit awards ranges from zero up to a maximum
of twice the target number of performance stock unit awards (“PSUs”) granted to the participant, based on our total shareholder return
relative to a designated peer group from the date of our IPO through December 31, 2019. Effective April 18, 2018, our Board of Directors
authorized and granted PSUs to certain key employees under the IAP. The actual number of shares that may be issued under the PSUs
ranges from zero up to a maximum of twice the target number of performance stock unit awards granted to the participant, based on our
total shareholder return relative to a designated peer group from January 1, 2018 through December 31, 2020. Compensation expense is
recorded ratably over the corresponding requisite service period. The fair value of performance stock unit awards is determined using a
Monte Carlo probability model. Grant recipients do not have any shareholder rights until performance relative to the peer group has been
determined following the completion of the performance period and shares have been issued. For the years ended December 31, 2018,
2017 and 2016 the recorded stock compensation expense for the performance stock units was  $2.0 million, $0.4 million and $0,
respectively.

At December 31, 2018, the Company had approximately $516.0 million of federal net operating loss carryforwards that will begin to
expire in 2032 and state net operating losses of approximately $50.0 million that will begin to expire in 2024. Utilization of net operating
loss carryforwards may be limited due to past or future ownership changes. As of December 31, 2018, the Company was no longer in a
cumulative book loss for the current and two prior years. Based on its estimate of future taxable income, the Company determined it is
more likely than not that it will utilize its deferred tax assets. Accordingly, the valuation allowance against its state deferred tax assets was
reversed.

The Company’s U.S. federal income tax returns for the years ended December 31, 2015 through December 31, 2017 remain open to
examination by the Internal Revenue Service under the applicable U.S. federal statute of limitations provisions. The various states in which
the Company is subject to income tax are generally open to examination for the tax years ended after December 31, 2014.

On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs
Act (“Tax Act”).  The Tax Act makes broad and complex changes to the U.S. tax code including, but not limited to (1) reducing the U.S.
federal corporate tax rate from 35% to 21%, (2) eliminating the corporate alternative minimum tax (“AMT’’) and changing how existing
AMT credits can be realized, (3) creating a new limitation on deductible interest expense, (4) changes to bonus depreciation, and (5)
changing rules related to use and limitations of net operating loss carryforwards for tax years beginning after December 31, 2017. We have
completed our analysis of the Tax Act. The only material items that impacted the Company’s consolidated financial statements in 2017
were bonus depreciation and the corporate rate reduction. While the corporate rate reduction was effective January 1, 2018, we accounted
for the effect of the rate change during the year ended December 31, 2017,

the year of enactment. Consequently, we recorded a $3.4 million decrease to the net deferred tax liability, with a corresponding net
adjustment to deferred tax benefit.

In June 2006, the FASB issued FASB Interpretation (FIN) No. 48, Accounting for Uncertainty in Income Taxes — an interpretation of

FASB Statement No. 109 (subsequently codified as ASC 740‑10, Income Taxes, Under FASB Statement No. 168, The FASB Accounting
Standards Codification and the Hierarchy of Generally Accepted Accounting Principles — a replacement of FASB Statement No. 162).
ASC 740‑10 prescribes a comprehensive model for recognizing, measuring, presenting, and disclosing in the consolidated financial
statements tax positions taken or expected to be taken on a tax return, including a decision to file or not to file in a particular jurisdiction.

The Company evaluated all tax positions and determined that the aggregate exposure under ASC 740‑10 did not have a material effect

on the consolidated financial statements during the year ended December 31, 2018, 2017 and 2016. Therefore, no adjustments have been
made to the consolidated financial statements related to the implementation of ASC 740‑10. The Company will continue to evaluate its tax
positions in accordance with ASC 740‑10 and will recognize any future effect as a charge to income in the applicable period.

Income tax penalties and interest assessments recognized under ASC 740‑10 are accrued as a tax expense in the period that the
Company’s taxes are in an uncertain tax position. Any accrued tax penalties or interest assessments will remain until the uncertain tax
position is resolved with the taxing authorities or until the applicable statute of limitations has expired.

16. RELATED‑PARTY TRANSACTIONS

The Company leases its corporate offices from a related party pursuant to a five‑year lease agreement with a five‑year extension option
requiring a base rent of $0.1 million per year. The Company also leases five properties adjacent to the corporate office from related parties
with annual base rents of $0.03 million, $0.03 million, $0.1 million, $0.1 million, and $0.2 million.

For the years ended December 31, 2018, 2017 and 2016, the Company paid approximately $0.4 million, $0.3 million and $0.2 million,

respectively, for the use of transportation services from a related party.

The Company also rents equipment in Elk City, Oklahoma from a related party. For the years ended  December 31, 2018, 2017 and

2016, the Company paid $0.2 million, $0.2 million and $0.2 million, respectively.

At December 31, 2018, 2017 and 2016, the Company had $0.01 million, $0.02 million and $0 in payables, respectively, and

approximately $0, $0 and $0.04 million in receivables, respectively, for related parties for services provided.

All agreements pertaining to realty property and equipment were entered into during periods where the Company had limited liquidity

and related parties secured them on behalf of the Company. All related party receivables and payables are immaterial and have not been
separately shown on the face of the financial statements.

17. COMMITMENTS AND CONTINGENCIES

Operating Lease — The Company has various operating leases for office space and certain property and equipment. For the years
ended December 31, 2018, 2017 and 2016, the Company recorded operating lease expense of $1.7 million, $1.4 million and $1.4 million,
respectively. Required remaining lease payments for each fiscal year are as follows:

18. EQUITY CAPITALIZATION

Credit Amendment Equity Infusion

In connection with the Term Loan and Revolving Credit Facility amendment dated June 8, 2016 (see Note 9), ECP and its related
affiliates along with other shareholders infused $40.4 million of equity into the Company and we issued 18,007,328 additional shares of
common stock.

On November 9, 2017, ECP sold 13,800,000 shares of its common stock holdings in a secondary offering at $15.07 per share, and sold

all of their remaining holdings in October of 2018.

Convertible Preferred Stock

On December 27, 2016, we completed a private placement offering of $170.0 million, issuing 16,999,990 shares of Series A
nonparticipating convertible preferred stock, par value $0.001 per share. Costs associated with the offering were approximately $7.0
million, resulting in net proceeds to the Company of approximately $163.0 million.

As of December 31, 2016, 16,999,990 shares of Series A convertible preferred stock were issued and outstanding, convertible into

common stock at the conversion price per the private placement agreement. In connection with our IPO, all 16,999,990 shares of our
outstanding Series A Preferred Stock converted to common stock on a 1:1 basis.

Initial Public Offering

On March 22, 2017, we consummated our IPO in which 25,000,000 shares of our common stock, par value $0.001 per share, were sold

at a public offering price of $14.00 per share, with 13,250,000 shares issued and sold by the Company and $11,750,000 shares sold by
existing stockholders.

At December 31, 2018 and 2017, the Company had 100,190,126 and 83,039,854 shares outstanding, respectively.

PRESSURE PUMPING SERVICES AGREEMENT

Execution Version

#5795049

This Pressure Pumping Services Agreement (this “Agreement”), effective as of the Effective Date (as defined in Article 25), is
between  Pioneer  Natural  Resources  USA,  Inc.,  a  Delaware  corporation  with  its  principal  place  of  business  at  5205  North
O’Connor  Blvd.,  Suite  200,  Irving,  Texas  75039  (“Company”),  and  ProPetro  Services,  Inc.,  a  Texas  corporation  with  its
principal place of business at 1706 S. Midkiff, Bldg. B, Midland, Texas 79701 (“ Contractor”). Company and Contractor are
sometimes hereinafter individually referred to as a “Party,” and collectively as the “Parties.”

WHEREAS, Company is the operator of certain oil and gas wells drilled and to be drilled in certain areas;

WHEREAS,  Company  desires  Contractor  to  provide  dedicated  hydraulic  fracturing  Fleets  (as  defined  in Article 3)  to
Company  for  the  performance  of  fracture  stimulation  pumping  services,  including  all  pump  down  operations  associated
therewith, and provision of associated products in connection with Company’s operations (the “Services”); and

WHEREAS,  Contractor  desires  to  perform,  and  represents  that  it  has  fully-trained  personnel  capable  of  performing

Services as required by Company;

NOW,  THEREFORE,  for  and  in  consideration  of  the  covenants  and  promises  herein  contained,  and  other  good  and

valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the Parties hereto agree as follows:

1. Master Service/Sales Agreement.  This Agreement  is  subject  to  the  terms  and  conditions  of  that  certain Amended  and
Restated Master Service/Sales Agreement by and between Company and Contractor dated May 16, 2016 (as amended,
supplemented or otherwise modified, the “MSSA”) which is hereby incorporated by reference into this Agreement. In
the event of any conflict or inconsistency between the terms and conditions of the MSSA and this Agreement, the terms
of this Agreement shall govern.

2. Term.

(a) The term of this Agreement shall begin on the Effective Date and shall continue for a period ending December 31,
2028 (the “Term”); provided, that Company shall have the right, exercisable in its sole discretion, to terminate this
Agreement (a) in whole or (b) in part, with respect to one or more Fleets, effective as of December 31 of each of the
calendar years 2022, 2024 and 2026 by providing written notice thereof to Contractor not later than July 1 of such
calendar year. Following receipt of written notice from Company to commence initial mobilization, Contractor shall
be  responsible  for  the  mobilization  and  demobilization  of  Contractor’s  personnel  and  equipment  and  the
performance of the Services in accordance with this Agreement. The Parties anticipate that such commencement will
occur on or about January 1, 2019 (“Commencement Date”).

(b) This  Agreement  supersedes  and  replaces  that  certain  Pressure  Pumping  Services  Agreement  by  and  between
Company and Contractor dated January 23, 2017 (as amended, supplemented or otherwise modified, the “Existing
PPSA”) in all respects effective as of the Effective Date. Except as provided in this Article 2(b), commencing on the
Effective  Date,  (i)  the  Parties  hereby  agree  to  terminate  the  Existing  PPSA,  (ii)  Contractor  shall  cease  providing
services  to  Company,  and  Company  will  cease  obtaining  services  from  Contractor,  pursuant  to  the  terms  and
conditions set forth in the Existing PPSA, and (iii) Contractor will commence providing Services to Company, and
Company will commence obtaining Services from Contractor, pursuant to the terms and conditions set forth in this
Agreement. Neither Party will be deemed to have waived, or to have released the other Party from, any claim, issue
or  dispute  arising,  becoming  known  or  discovered  or  asserted  after  the  Effective  Date  but  relating  to  a  Party’s
performance  or  nonperformance  under  the  Existing  PPSA. The  resolution  of  any  such  claim,  issue  or  dispute  will
continue  to  be  governed  by  the  terms  and  conditions  of  the  Existing  PPSA. In  addition,  Company  will  remain
obligated  to  pay  to  Contractor  all  amounts  properly  payable  by  Company  pursuant  to  the  Existing  PPSA  that,  in
accordance with the regular invoice and payment process, had not been invoiced to or paid by Company as of the
Effective Date. The terms of the Existing PPSA shall survive its termination and remain in full effect for purposes of
the matters described in this Article 2(b).

3. Pricing  and  Scope  of

Work.

(a) Contractor  shall  perform  the  Services  in  accordance  with  each  applicable  work  order  or  other  instrument  used  by
Company to authorize the performance of the Services and Contractor’s net price book that is mutually agreed to
between Company and Contractor (the “Net Price Book”). Rates for items not included in  the  Net  Price  Book  or
expressly  provided  herein  shall  be  agreed  upon  in  writing  by  the  Parties.  The  Net  Price  Book  will  be  subject  to
adjustments as set forth in Article 4. Company shall not be liable for any markup by Contractor on goods or services
provided by any third party subcontractor or supplier of Contractor. Additionally, Company shall not be liable for
any  detention,  demurrage,  or  non-utilization  charges  incurred  by  Contractor  in  connection  with  trucking  services
provided by Contractor or its subcontractors in furtherance of the Services, except if and to the extent that any such
detention, demurrage, or non-utilization charges are directly caused by any member of the Company Group (as such
term is defined in the MSSA), as determined by Company in good faith.

(b) Beginning on the Commencement Date, Contractor shall deliver eight (8) hydraulic fracturing fleets to Company to
perform the Services (“Fleets”), with such Fleets dedicated exclusively to Company throughout the Term. For each
Fleet,  there  shall  be  (i)  sufficient  personnel  and  equipment  capable  of  sustaining  maximum  treating  pressures  of
10,000 pounds per square inch and maximum pump rates of 100 barrels per minute for each well in the performance
of the Services, (ii) on-site storage equipment capable of holding a minimum of 5,000,000 pounds of proppant, and
(iii) sufficient personnel and equipment capable of providing all pump down operations required in connection with
the Services. If Company’s job design for a well requires treating pressures or pump rates in excess of the amounts
set  forth  above,  Company  will  provide  Contractor  sufficient  notice  to  allow  Contractor  to  secure  any  additional
equipment and materials that may be necessary to satisfy such requirements. Contractor will be solely responsible
for  the  operation  of  the  equipment,  and  the  equipment  shall  remain  under  the  control  of  Contractor  at  all  times.
Contractor shall provide trained and qualified personnel to perform the Services. In satisfying its Fleet obligations
under this Agreement, Contractor will have the sole right to

-2-

determine the equipment included in each Fleet, subject to (i) Contractor’s compliance with the requirements of this
Agreement,  and  (ii)  Contractor  consulting  with  Company  within  a  reasonable  period  of  time  (but  at  least  ten  (10)
days) before changing the then-current configuration or components of any Fleet.

(c) Company hereby grants Contractor a right of first offer (“ROFO”) with respect to any coiled tubing services that
may  be  required  by  Company  as  part  of  the  Services  (the  “Coiled  Tubing  Services”),  subject  to  the  terms  and
conditions  set  forth  in  this Article  3(c).  If  Company  requires  any  Coiled  Tubing  Services,  then  Company  shall
provide Contractor with written notice thereof, identifying the location(s), time period(s) and other particulars with
respect  to  the  Coiled  Tubing  Services  that  Company  requires  (the  “ROFO  Offer”). If  Contractor  has  sufficient
coiled tubing equipment available to perform Coiled Tubing Services at the location(s) and during the time period(s)
required per a ROFO Offer, then Contractor shall provide such Coiled Tubing Services to Company under the terms
of this Agreement and the Pricing Agreement by and between Company and Contractor effective as of the Effective
Date. However,  if  Contractor  does  not  have  such  equipment  available  to  perform  Coiled  Tubing  Services  at  the
location(s) and during the time period(s) required per a ROFO Offer, then that ROFO Offer shall be of no further
force or effect, the ROFO granted herein shall automatically terminate and be null and void as to the subject Coiled
Tubing  Services,  and  Company  may  procure  such  Coiled  Tubing  Services  from  any  third  party. Notwithstanding
anything  to  the  contrary  contained  in  this Article 3(c):  (i)  Contractor  will  not  have  a  ROFO  with  respect  to  any
Coiled Tubing Services if, at the time that Company wishes to make a ROFO Offer to Contractor, Contractor is not
in compliance with the terms of this Agreement; and (ii) the ROFO granted herein shall automatically terminate and
be null and void with respect to any and all Coiled Tubing Services that Company requires after such date on which
Contractor has failed to meet any of the key performance indicators for the Coiled Tubing Services that are set forth
in Exhibit A.

4. Periodic 

Adjustments.

Pricing

(a) Effective as of such date that is six (6) months after the Effective Date and every six (6) months thereafter during the
Term  (each  a  “ Price Adjustment  Date”),  Contractor  shall  apply  a  price  adjustment  mechanism  that  is  mutually
agreed  to  between  Company  and  Contractor  (the  “PAM”)  to  the  materials  and  services  that  compose  the  then-
current standard job price that is mutually agreed to between Company and Contractor (the “Standard Job Price”).
Contractor, in consultation with Company, shall make adjustments to the unit prices of line items in the then-current
Net  Price  Book  necessary  to  achieve  a  revised  Standard  Job  Price  reflective  of  the  PAM  with  the  resulting
adjustments set forth in a revised Net Price Book to be prepared by Contractor. Such adjustments shall be effective
retroactively  and  prospectively  for  all  Services  that  are  commenced  during  the  applicable  six  (6)-month  period.
Contractor  shall  submit  the  revised  Net  Price  Book  and  a  revised  Standard  Job  Price  to  Company,  along  with  a
pricing memorandum in a form and format agreed upon by the Parties that details the application of the PAM, in
each case by the fifteenth (15th) day following the applicable Price Adjustment Date.

(b) If  a  Party  (i)  implements  new  technology  with  respect  to  the  Services  that  materially  improves  the  quality,
efficiency, capability, safety, or other performance metrics of the Fleets hereunder, or (ii) identifies new technology
that it believes would, if implemented with respect to the Services, achieve such improvements, then that Party will
provide  the  other  Party  notice  thereof. Promptly  thereafter,  the  Parties  will  conduct  good-faith  negotiations  (i)  if
such technology is

-3-

not yet implemented, to agree to a commercially reasonable plan to acquire and implement such new technology; and
(ii)  to  make  equitable  adjustments  to  the  Net  Price  Book,  the  composition  of  a  Fleet,  and  the  minimum  Efficiency
Rate and Per Pad Stage Attainment Rate to account for such improvements.

5.

Invoicing;
Credits.

(a) Contractor shall issue invoices to Company for the Services on a per-well basis and otherwise in accordance with the

MSSA.

(b) Without limiting Company’s rights or remedies under this Agreement or at law or in equity, Company may deduct
any amount that Company determines in good faith is owed by Contractor to Company under this Agreement (each
such deduction, a “Credit”) from any charges invoiced by Contractor hereunder or against other amounts owed by
Company to Contractor under this Agreement. Company shall notify Contractor in advance of applying any Credit
against  any  charges  invoiced  by  Contractor  hereunder  or  against  other  amounts  owed  by  Company  to  Contractor
under this Agreement. Such Credits shall not limit or affect any right of Company to recover any damages incurred
by Company as a result of any failure by Contractor to perform the Services or any other obligation contemplated by
this Agreement. Credits shall not expire and may be held by the Company until fully utilized. Upon the expiration or
any  termination  of  this Agreement,  any  remaining  Credits  shall  be  paid  or  credited  to  Company,  at  Company’s
election and in its sole discretion.

6. Option  for  Additional  Fleets.  Notwithstanding  anything  contained  in Article  3  above,  the  Parties  agree  that  in
consideration of U.S. $10 paid by Company to Contractor, the receipt and sufficiency of which is hereby acknowledged,
Company  has  the  option,  but  not  the  obligation,  to  add  additional  incremental  Fleets  from  Contractor  (each,  an
“Additional Fleet”), but not more than two (2) Additional Fleets in any calendar year, which Additional Fleets shall be
under  the  same  terms  and  conditions  as  set  forth  in  this Agreement. Such  option  shall  expire  on  December  31,  2022.
Company shall provide Contractor with nine (9) months’ written notice of its election to exercise its option to add an
Additional Fleet. In addition, during the first year of the Term, Company may add one (1) additional incremental Fleet
upon at least sixty (60) days’ written notice to Contractor that will consist of Contractor’s then available equipment and
will  not  constitute  a  new  order  (the  “First  Year Additional  Fleet”). The  Parties  shall  work  together  in  good  faith  to
determine  mobilization  dates  for  the  First  Year Additional  Fleet  and  each Additional  Fleet,  as  applicable;  provided,
however, Company may postpone the agreed mobilization date for the First Year Additional Fleet by a period of time
designated by Company (such postponement period not to exceed thirty (30) days, unless otherwise agreed in writing by
the Parties), provided that Company notifies Contractor in writing of such postponement at least thirty (30) days prior to
the original agreed mobilization date for the First Year Additional Fleet.  Commencing on their applicable mobilization
dates, the First Year Additional Fleet and each Additional Fleet shall be considered a Fleet for all purposes hereof.

7. Efficiency  Rate;  Non-Productive 

Time; 

Equipment

Mobilization.

(a) Contractor shall be capable of performing the Services in accordance with the requirements of this Agreement on a
twenty-four  (24)  hour  basis,  seven  (7)  days  a  week. For  each  well  where  Contractor  is  performing  the  Services,
Contractor  shall  perform  the  Services  at  an  efficiency  rate  of  at  least  ninety  percent  (90%)  (“Efficiency  Rate”),
which  shall  be  calculated  as  set  forth  in Exhibit B;  provided,  however,  that  for  purposes  of  this Article 7,  neither
Fleet Mobilization

-4-

Time (defined below) nor any time period that the Parties may agree to, including a holiday or time period associated
with  a  weather  event,  shall  be  Company  or  Contractor  Non-Productive  Time  (defined  below). “Fleet  Mobilization
Time” is the amount of time, as is mutually agreed to between Company and Contractor, that each Fleet is allowed to
move between pads in order to set up and be Mobilized on Location. A Fleet will be “ Mobilized on Location” when
the Fleet is fully mobilized on a Company well-site and fully capable of performing the Services.

(b) Subject to Article 7(a), (i) each hour or fractional hour that Contractor does not perform the Services when a Fleet is
Mobilized on Location (as defined below) for any reason, other than White Space or an Idle Period (each defined
below),  that  is  attributable  to  the  sole  fault  of  any  member  of  the  Company  Group,  will  be  “Company  Non-
Productive Time” or “Company NPT” and (ii) each hour or fractional hour that Contractor does not perform the
Services  for  any  reason  not  attributable  to  Company  NPT  will  be  “Contractor  Non-Productive  Time”  or
“Contractor NPT.”

8. Stage Attainment  Rate.  Upon  the  completion  of  each  pad,  each  Contractor  Fleet  shall  be  required  to  achieve  a  Stage
Attainment Rate (as defined below) of ninety-five (95%) (the “Per Pad Stage Attainment Rate”). “Stage Attainment
Rate” shall be determined as follows:

First, calculate the target number of Stages to be attained for a day of Services by a Fleet:

Third, upon that Fleet’s completion of Services for the subject pad,
average the daily Stage Attainment Rates applicable to such pad. An example calculation of the Stage Attainment Rate is
attached hereto as Exhibit C.

“Pump  Time”  means  the  planned  time  to  complete  a  Stage,  given  the  fluid  volume  and  pump  rate  for  such  Stage,
according to Company’s design.

A “Stage” means the perforation of a portion of the well casing and injection of fluid into the perforated zone, according
to Company’s design. A Stage is completed when a plug is set that completely seals off the portion of the well casing that
was perforated and into which fracturing fluid was pumped according to Company’s design.

“Switch-Over Time” means the time that Company allots to Contractor to move its equipment between wells, according
to Company’s design.

9. Materials and Logistics. Company shall have the right, in Company’s sole discretion and upon at least ninety (90) days’
prior written notice to Contractor, to supply all or a portion of the proppant, proppant trucking, coiled tubing services,
friction reducer, high viscosity friction reducer, surfactant,

-5-

    
and  diesel  fuel  and  trucking  (collectively,  the  “Company  Provided  Materials”)  to  Contractor  for  purposes  of
Contractor’s performance of the Services, as well as the right to have Contractor provide such materials.  In the event that
Company  exercises  its  right  to  supply  any  of  the  Company  Provided  Materials,  Contractor  shall  make  corresponding
equitable adjustments to the unit prices contained in the then-current and each subsequent Net Price Book (and not simply
the  elimination  of  the  applicable  line  item(s)). As  of  the  Effective  Date,  Company  elects  to  provide  all  high  viscosity
friction reducer, friction reducer, surfactant and proppant. At Company’s election, Company reserves the right to supply
any other materials in furtherance of the performance of the Services; provided, however, that Company’s right to supply
any other materials in furtherance of the performance of the Services shall not apply if and to the extent that Contractor is
expressly  required  to  purchase  any  quantity  of  any  such  materials  under  any  agreements  that  have  been  assigned  by
Company or Pioneer Natural Resources Pumping Services LLC to ProPetro Holding Corp. pursuant to that Purchase and
Sale  Agreement  by  and  among  Company,  Pioneer  Natural  Resources  Pumping  Services  LLC  and  ProPetro  Holding
Corp., dated November 12, 2018 (the “PSA”), in each case per the express terms of such agreements as of the date of their
assignment by Company (and not as they may be later amended or otherwise modified).

10. White
Space.

(a) “White Space” means any full day or period of consecutive full days during which a Fleet is capable of performing
the  Services  in  accordance  with  this Agreement,  but  is  not  scheduled  by  Company  to  perform  the  Services.  With
respect to each Fleet, White Space does not include: (i) the first ten (10) days of Fleet Mobilization Time per quarter;
(ii) any Fleet Mobilization Time to the extent Contractor’s time to move such Fleet between pads and set up and be
Mobilized on Location exceeds seventy-two (72) hours; (iii) any time period that a Fleet is Mobilized on Location;
or (iv) any time period during which a Fleet performs services for a third party customer of Contractor. The Parties
shall work together in good faith to maintain a schedule for the Services that minimizes, to the extent commercially
reasonable, the potential for White Space.

(b) Company  shall  advise  Contractor  of  any  anticipated  days  of  White  Space  for  a  Fleet  as  soon  as  is  reasonably
practicable. Company shall provide to Contractor at least seventy-two (72) hours’ notice of the date for the affected
Fleet to resume its performance of the Services following the anticipated White Space (the “Return Date”). Unless
otherwise expressly notified by Company in writing, the affected Fleet shall resume its performance of the Services
on such Return Date.

11. Idle

Periods.

(a) Should Company elect to idle a Fleet, Company may issue a written notice to Contractor regarding such election (an
“Idle Period Notice”). Any time period that a Fleet is idled pursuant to an Idle Period Notice is an “Idle Period.”
An  Idle  Period  shall  not  be  considered  White  Space. Upon  receipt  of  an  Idle  Period  Notice,  Contractor  shall  use
commercially  reasonable  efforts  to  employ  the  affected  Fleet  in  work  with  a  substitute  customer  during  any  such
anticipated Idle Period.

(b) During  an  Idle  Period,  Company  shall  not  enter  into  any  agreement  with  a  third  party  to  provide  stimulation
pumping services that could otherwise be timely performed by an idled Fleet in accordance with the terms of this
Agreement. If Company wishes to re-activate a Fleet idled pursuant to Article 11(a), Company shall provide at least
sixty (60) days’ written notice in advance of the Return Date for such Fleet in order to allow Contractor to timely
secure personnel and

-6-

equipment suitable for the Services. In the event that Contractor fails to achieve the Return Date set forth in a notice
issued  by  Company  in  accordance  with  this Article 11(b),  Contractor  shall  be  liable  to  Company  for  charges  in  an
amount  to  be  mutually  agreed  by  Company  and  Contractor  (such  amount,  the  “Return  Date  Overage Amount”).
Following  Contractor’s  receipt  of  notice  from  Company  of  a  Return  Date  applicable  to  an  idled  Fleet,  Contractor
shall  not  enter  in  any  commitment  as  to  such  Fleet  that  extends  beyond  the  designated  Return  Date. However,
notwithstanding the foregoing, if, prior to Contractor’s receipt of notice by Company of a Return Date for an idled
Fleet, Contractor has entered into a binding agreement with a third party for such Fleet for a term that extends beyond
the  Return  Date  specified  by  Company,  (i)  Contractor  shall  have  no  liability  to  Company  for  any  Return  Date
Overage Amounts applicable to days for which such Fleet is so bound; and (ii) Company may enter into an agreement
with a third party to perform services that would otherwise be provided by such Fleet.

12. Reservation Periods. Within ten (10) business days following the beginning of each calendar quarter during the Term,
Contractor shall determine the total number of days attributable to (i) White Space for all Fleets that were not subject to
an Idle Period during the preceding calendar quarter (the “White Space Period”), and (ii) Idle Period(s) for each Fleet
that was subject to an Idle Period.

13. Venue.  Each Party consents to personal jurisdiction in any action brought in the United States federal and state courts
located  in  the  State  of  Texas  with  respect  to  any  dispute,  claim  or  controversy  arising  out  of  or  in  relation  to  or  in
connection  with  this  Agreement,  and  each  of  the  Parties  agrees  that  any  action  with  respect  to  any  such  dispute,
controversy, or claim will be determined exclusively in a state or federal district court located in Dallas County, Texas.
EACH PARTY HEREBY IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY
OBJECTION  WHICH  THEY  MAY  NOW  OR  HEREAFTER  HAVE  TO  THE  VENUE  OF ANY  SUCH  DISPUTE
ARISING OUT OF THIS AGREEMENT BROUGHT IN SUCH COURT OR ANY DEFENSE OF INCONVENIENT
FORUM  FOR  THE  MAINTENANCE  OF  SUCH  DISPUTE. EACH  PARTY  HEREBY  IRREVOCABLY  WAIVES
ITS  RIGHT  TO A  JURY  TRIAL  WITH  RESPECT  TO ANY  CLAIM  BROUGHT  BY  IT  OR  BROUGHT  BY  THE
OTHER PARTY THAT ARISES OUT OF THIS AGREEMENT.

14. Remedies.

(a) If Contractor fails to perform any Services in accordance with this Agreement, Company may exercise any one or

more of the following remedies:

(i) provide the affected Services itself or procure such Services from an alternate source, in which case Contractor
shall  reimburse  Company  for  the  costs  incurred  by  Company  in  providing  or  procuring  such  Services  to  the
extent  that  such  costs  exceed  the  applicable  Net  Price  Book  prices  for  such  Services  (even  if  such  Net  Price
Book prices were not paid by Company);

(ii) require Contractor to procure the affected Services from a third party selected by Company and have such third

party provide such Services to Company at no additional cost to Company;

(iii) require Contractor to reimburse Company for any amounts paid by Company to Contractor with respect to the

affected Services; and

-7-

(iv) require  Contractor  to  take  any  other  actions  that  the  Company  deems  to  be  necessary  to  timely  address
Contractor’s  failure  to  perform,  which  may  include  (1)  re-performing  the  relevant  job,  (2)  supplementing  the
affected Fleet or crew, and (3) replacing the affected Fleet or crew.

Any period(s) of time during which is Company is exercising any of the remedies set forth in this Article 14(a) shall
not  be  considered  Company  NPT,  Contractor  NPT,  White  Space,  or  an  Idle  Period  for  the  Fleet(s)  whose
performance Company is seeking to remedy.

(b) The rights and remedies of Company provided in this Article 14 are not exclusive, and are in addition to any other
rights  and  remedies  provided  under  this Agreement  or  at  law  or  in  equity,  notwithstanding  anything  herein  to  the
contrary.

15. Termination.

(a) Either Party may terminate this Agreement by delivery of a written termination notice to the other Party, in the event
the  other  Party  becomes  insolvent,  files  a  petition  in  bankruptcy,  has  a  petition  in  involuntary  bankruptcy  filed
against such Party (which petition is not terminated within sixty (60) days of filing), or makes an assignment for the
benefit  of  its  creditors.  Such  termination  shall  be  effective  immediately  upon  delivery  of  written  notice  of
termination.

(b) Company  may,  by  delivery  of  a  written  termination  notice  to

Contractor:

(i) Terminate  this Agreement  with  respect  to  a  particular  Fleet  if  such  Fleet  fails  to  achieve  the  Per  Pad  Stage
Attainment Rate (A) for three (3) consecutive pads or (B) for three (3) pads within any rolling six (6)-pad period.
Such termination shall be effective upon the date specified in Company’s termination notice to Contractor and
Company shall not have any termination liability to the Contractor under this Agreement; or

(ii) Terminate this Agreement in its entirety in the event of a Change in Control.  “Change in Control” means the

occurrence of any of the following events:

(1) The  acquisition  by  any  person  of  beneficial  ownership  (as  defined  in  Rule  13d‑3  of  the  Securities Act  of
1934)  of  securities  of  ProPetro  Holding  Corp.,  a  Delaware  corporation  (“Parent”),  that,  together  with
securities  held  by  such  person,  constitutes  fifty  percent  (50%)  or  more  of  either  (x)  the  then  outstanding
shares of common stock of Parent (the “Outstanding Parent Stock”) or (y) the combined voting power of
the  then  outstanding  voting  securities  of  Parent  entitled  to  vote  generally  in  the  election  of  directors  (the
“Outstanding  Parent  Voting  Securities”);  provided,  however,  that  for  these  purposes,  an  acquisition  by
any person pursuant to a transaction which complies with clauses (A), (B) and (C) of clause (3) below shall
not constitute a Change in Control;

(2) A majority of the members of the board of directors of Parent (the “Board”) is replaced during any twelve
(12)-month period by directors whose appointment or election is not endorsed by a majority of the members
constituting the Board prior to the date of the appointment or election;

(3) Consummation of a reorganization, merger or consolidation or sale or other disposition of all or substantially

all of the assets of Parent or an acquisition of assets of another

-8-

entity (a “Business Combination”), in each case, unless, following such  Business  Combination,  (A)  all  or
substantially  all  of  the  individuals  and  entities  who  were  the  beneficial  owners,  respectively,  of  the
Outstanding  Parent  Stock  and  Outstanding  Parent  Voting  Securities  immediately  prior  to  such  Business
Combination beneficially own, directly or indirectly, more than fifty percent (50%) of, respectively, the then
outstanding shares of common stock or common equity interests and the combined voting power of the then
outstanding voting securities entitled to vote generally in the election of directors or other governing body, as
the case may be, of the entity resulting from such Business Combination (including, without limitation,  an
entity  which  as  a  result  of  such  transaction  owns  Parent  or  all  or  substantially  all  of  Parent’s  assets  either
directly  or  through  one  or  more  subsidiaries)  in  substantially  the  same  proportions  as  their  ownership,
immediately  prior  to  such  Business  Combination  of  the  Outstanding  Parent  Stock  and  Outstanding  Parent
Voting Securities, as the case may be, (B) no person beneficially owns, directly or indirectly, fifty percent
(50%) or more of, respectively, the then outstanding shares of common stock or common equity interests of
the entity resulting from such Business Combination or the combined voting power of the then outstanding
voting  securities  of  such  entity  except  to  the  extent  that  such  ownership  results  solely  from  ownership  of
Parent that existed prior to the Business Combination and (C) at least a majority of the members of the board
of directors or similar governing body of the entity resulting from such Business Combination, at the time of
the  execution  of  the  initial  agreement,  or  of  the  action  of  the  Board,  providing  for  such  Business
Combination, were members of the board of directors of Parent as of the Effective Date, or became members
of the board of directors of Parent after the Effective Date and whose election or appointment or nomination
for  election  by  Parent’s  stockholders  was  approved  by  a  vote  of  at  least  a  majority  of  the  directors  then
comprising the board of directors of Parent;

(4) Approval  by  the  stockholders  of  Parent  of  a  complete  liquidation  or  dissolution  of

Parent;

(5) Contractor is no longer a wholly owned subsidiary (or a wholly owned subsidiary of one or more wholly

owned subsidiaries) of Parent; and

(6) The consummation of a reorganization, merger, consolidation, sale or other disposition of all or substantially
all of the assets of Contractor to a person that is not wholly owned subsidiary (or a wholly owned subsidiary
of one or more wholly owned subsidiaries) of Parent.

(c) Contractor may, by delivery of a written termination notice to Company, terminate this Agreement with respect to a
particular Fleet, if Company fails to pay any undisputed invoice for Services properly performed by such Fleet or
other payment hereunder when such invoice or payment is due and payable hereunder, unless within sixty (60) days
following  Company’s  receipt  of  a  written  notice  from  Contractor  to  Company  of  such  non-payment,  Company
makes such payments in accordance herewith.

16. Assignment. This Agreement shall inure to the benefit of and be binding upon the successors and/or permitted assigns of
each  Party  hereto.  This Agreement  shall  not  be  assigned,  directly  or  indirectly  (whether  by  merger,  operation  of  law,
change in majority ownership of any entity directly or indirectly controlling Contractor or otherwise) in whole or in part,
by either Party without the prior written

-9-

consent of the other Party (such consent not to be unreasonably withheld, conditioned or delayed), except that Company
may assign and transfer this Agreement to any affiliate or subsidiary of Company without such consent. Without in any
way limiting any of the foregoing provisions of this Article 16, if Contractor assigns this Agreement, in whole or in part,
the  assignee  (in  the  case  of  a  direct  assignment)  and  the  ultimate  parent  of  such  assignee  (in  the  case  of  a  direct
assignment) or the ultimate parent of Contractor (in the case of an indirect assignment after giving effect to such indirect
assignment) shall be deemed for all purposes to have agreed (in addition to Contractor) to perform and be obligated for
the  obligations  of  Contractor  under  this  Agreement.  No  assignment  of  this  Agreement  by  Contractor  shall  release
Contractor from any of its obligations under this Agreement. Any assignment or attempted assignment of this Agreement
that is not in accordance with this Article 16 shall be deemed null and void.

17. Confidentiality.  Except  as  expressly  authorized  hereunder  or  by  prior  written  agreement  by  an  officer  of  Company,
Contractor  shall  make  no  public  announcement  concerning  this  Agreement  and  all  information  contained  herein  or
related to the Services is “Company Confidential Information” (as defined in the MSSA) and  shall  be  held  in  strict
confidence by Contractor. Contractor shall not disclose, publish, release, transfer or otherwise make available Company
Confidential Information in any form to, or for the use or benefit of, any person or entity without Company’s express
written consent. Contractor shall disclose Company Confidential Information only to its personnel who have a need to
know in performance of the Services, and Contractor shall ensure that Company Confidential Information is kept strictly
confidential by such personnel in accordance with this Article 17.

18. Health, 

Safety, 

Environment,

Taxes.

(a) Contractor  shall  be  solely  responsible  for  Contractor  Group’s  (as  defined  in  the  MSSA)  safe  behavior  and  work
practices  while  on  any  Company  location. Contractor  must  immediately  report  all  incidents  (including  safety
hazards,  near  misses,  motor-vehicle  accidents,  injuries,  illnesses,  spills,  and  property  damage)  that  occur  on  a
Company work site or location to the appropriate on-site Company representative. Contractor shall intervene and, if
appropriate, stop work activity to ensure safety and operational integrity. If Company performs a root cause analysis
(“RCA”) or other investigation of an incident, Contractor will fully cooperate with Company and promptly provide
all reasonable access, assistance, and materials that Company may request; provided, that such provision would not
materially  violate  Contractor’  applicable  policies. For  any  Contractor  Group  incident  occurring  on  a  Company
location, Contractor shall complete an incident report and conduct an incident investigation (to include an RCA) and
deliver  the  non-privileged  portions  of  these  to  a  Company  representative  within  one  (1)  week  of  the  incident;
provided, that if the circumstances of the incident are such that completion of Contractor’s incident investigation and
RCA will, in good faith, require a longer period, then Contractor will deliver an initial report of the incident within
one  (1)  week  of  the  incident  and  the  non-privileged  portions  of  the  final  investigation  and  RCA  as  promptly  as
possible. Contractor’s RCA shall indicate how and why the incident occurred and identify actions that Contractor
will take or is taking to prevent a future occurrence of the incident.

(b) After an incident, Company may place Contractor on a mutually agreed-upon improvement plan, which may include

any of the following:

-10-

(i) Health,  safety  and  environmental  training  conducted  by  Company,  Contractor,  or  a  third

party;

(ii) temporary  or  permanent  removal  of  any  member  of  Contractor  Group  from

location;

(iii) reporting  of  improvement  throughout  the  process;

and

(iv) regular 

inspection 

of 

equipment 

or

personnel.

(c) If any member of Contractor Group exhibits behavior that creates a safety concern and does not reflect the corrective
actions agreed-upon by Contractor and Company, and that personnel does not rectify the behavior within thirty (30)
days,  then  Company  may  terminate  this Agreement,  without  liability,  other  than  for  amounts  owed  for  Services
performed up to the time of termination, as of any date specified in a written notice to Contractor.

(d) With  respect  to  the  personnel  performing  the  Services  pursuant  to  this  Agreement,  Contractor  shall  be  solely
responsible for compliance with all laws applicable to Contractor’s employees, including without limitation all laws
and regulations regarding (i) the payment of wages and other compensation, (ii) the payment of any taxes, licenses,
fees and other assessments levied upon the wages of the Contractor Group, as described in Section 9 of the MSSA,
including any such taxes or similar assessments payable by withholding, and the payment of applicable employment
taxes and other withholdings, and (iii) all other employment obligations and liabilities.

(e) Without duplication of Article 18(d), Contractor shall pay or cause to be paid all taxes, charges and assessments of
every kind and character required by statute or by order of any taxing authority with respect to the provision of the
Services.  No  Party  shall  be  responsible  nor  liable  for  any  taxes  or  other  charges  levied  or  assessed  against  the
facilities or property of the other Party, including ad valorem taxes (however assessed), or against the net worth or
capital stock of such Party.

19. Notices.  All  notices,  requests,  demands  and  other  communications  which  are  required  or  may  be  given  under  this
Agreement shall be in writing and shall be deemed to have been duly given (i) when received if personally delivered; (ii)
the day after it is sent, if sent for next day delivery to a domestic address by recognized overnight delivery service (e.g.,
DHL, UPS or Federal Express); (iii) upon receipt, if sent by certified or registered mail, return receipt requested; or (iv)
when  verified  by  automated  receipt  or  electronic  logs  if  sent  by  email.  In  each  case  notice  shall  be  sent  as  indicated
below:

INDEMNIFICATION AGREEMENT

Execution Version

This  Indemnification Agreement  (“ Agreement”)  is  made  as  of  February  11,  2019  by  and  between  ProPetro

Holding Corp., a Delaware corporation (the “Company”), and the undersigned (“Indemnitee”).

RECITALS

WHEREAS,  highly  competent  persons  have  become  more  reluctant  to  serve  publicly-held  corporations  as
directors  or  in  other  capacities  unless  they  are  provided  with  adequate  protection  through  insurance  or  adequate
indemnification against inordinate risks of claims and actions against them arising out of their service to and activities
on behalf of the corporation;

WHEREAS, the Board of Directors of the Company (the “ Board”) has determined that, in order to attract and
retain qualified individuals, the Company will maintain on an ongoing basis, at its sole expense, liability insurance to
protect persons serving the Company and its subsidiaries from certain liabilities;

WHEREAS,  directors,  officers,  and  other  persons  in  service  to  corporations  or  business  enterprises  are  being
increasingly  subjected  to  expensive  and  time-consuming  litigation  relating  to,  among  other  things,  matters  that
traditionally would have been brought only against the Company or business enterprise itself;

WHEREAS, the Company’s certificate of incorporation (the “ Certificate of Incorporation ”) and bylaws (the
“Bylaws”)  require  indemnification  of  the  officers  and  directors  of  the  Company.  Indemnitee  may  also  be  entitled  to
indemnification  pursuant  to  the  General  Corporation  Law  of  the  State  of  Delaware  (“DGCL”).  The  Certificate  of
Incorporation, the Bylaws and the DGCL expressly provide that the indemnification provisions set forth therein are not
exclusive, and thereby contemplate that contracts may be entered into between the Company and members of the board
of directors, officers and other persons with respect to indemnification;

WHEREAS,  the  Board  has  determined  that  the  increased  difficulty  in  attracting  and  retaining  qualified
individuals to serve as directors and officers is detrimental to the best interests of the Company’s stockholders and that
the Company should act to assure such persons that there will be increased certainty of such protection in the future;

WHEREAS,  it  is  reasonable,  prudent  and  necessary  for  the  Company  contractually  to  obligate  itself  to
indemnify, and to advance expenses on behalf of, such persons to the fullest extent permitted by applicable law so that
they will serve or continue to serve the Company free from undue concern that they will not be so indemnified;

WHEREAS,  this  Agreement  is  a  supplement  to  and  in  furtherance  of  the  Certificate  of  Incorporation  and
Bylaws and any resolutions adopted pursuant thereto, and shall not be deemed a substitute therefor, nor to diminish or
abrogate any rights of Indemnitee thereunder;

WHEREAS, Indemnitee does not regard the protection available under the Bylaws and insurance as adequate in
the present circumstances, and may not be willing to serve as an officer or director without adequate protection, and the
Company desires Indemnitee to serve in such capacity. Indemnitee is willing to serve, continue to serve and to take on
additional service for or on behalf of the Company on the condition that Indemnitee be so indemnified; and

WHEREAS,  Indemnitee  has  certain  rights  to  indemnification  and/or  insurance  provided  by  the  Pioneer
Stockholder  (as  defined  below)  or  affiliates  of  the  Pioneer  Stockholder  that  Indemnitee  and  the  Pioneer  Stockholder
intend to be secondary to the primary obligation of the Company to indemnify Indemnitee as provided herein, with the
Company’s acknowledgment of and agreement to the foregoing being a material condition to Indemnitee’s willingness
to serve as a director or in any other capacity for the Company or any of its subsidiaries or any Enterprise (as defined
below).

NOW, THEREFORE, in consideration of the premises and the covenants contained herein, the Company and

Indemnitee do hereby covenant and agree as follows:

Section  1.

Services  to  the  Company.  Indemnitee  agrees  to  serve  as  a  director  of  the  Company.
Indemnitee may at any time and for any reason resign from such position (subject to any other contractual obligation or
any  obligation  imposed  by  operation  of  law),  in  which  event  the  Company  shall  have  no  obligation  under  this
Agreement  to  continue  Indemnitee  in  such  position.  This Agreement  shall  not  be  deemed  an  employment  contract
between  the  Company  (or  any  of  its  subsidiaries  or  any  Enterprise)  and  Indemnitee.  Indemnitee  specifically
acknowledges that Indemnitee’s employment with the Company (or any of its subsidiaries or any Enterprise), if any, is
at  will,  and  the  Indemnitee  may  be  discharged  at  any  time  for  any  reason,  with  or  without  cause,  except  as  may  be
otherwise  provided  in  any  written  employment  contract  between  Indemnitee  and  the  Company  (or  any  of  its
subsidiaries or any Enterprise), other applicable formal severance policies duly adopted by the Board, or, with respect

to service as a director or officer of the Company, by the Certificate of Incorporation, the Bylaws and the DGCL. The
foregoing notwithstanding, this Agreement shall continue in force after Indemnitee has ceased to serve as a director of
the Company.

such a liquidation, sale, or disposition in one transaction or a series of related transactions; and

(v)     Other  Events.  There  occurs  any  other  event  of  a  nature  that  would  be  required  to  be
reported in response to Item 6(e) of Schedule 14A of Regulation 14A (or a response to any similar item on any similar

Liabilities and damages arising out of or relating to this Agreement or its engagement pursuant hereto.

Company  or  otherwise  and  whether  of  a  civil,  criminal,  administrative  or  investigative  nature,  in  which  Indemnitee
was, is or will be involved as a party or otherwise by reason of the Corporate Status of Indemnitee, by reason of any
action taken by Indemnitee or of any action or inaction on Indemnitee’s part while acting in such Corporate Status, in
each  case  whether  or  not  serving  in  such  capacity  at  the  time  any  Liability  or  Expense  is  incurred  for  which
indemnification, reimbursement, or advancement of Expenses can be provided under this Agreement. If the Indemnitee
believes in good faith that a given situation may lead to or culminate in the institution of a Proceeding, this shall be

best interests of the participants and beneficiaries of an employee benefit plan shall be deemed to have acted in manner
“not opposed to the best interests of the Company” as referred to in this Agreement.

Section 3.     Indemnity in Third-Party Proceedings . The  Company  shall  indemnify  Indemnitee  in  accordance
with  the  provisions  of  this Section 3  if  Indemnitee  is,  or  is  threatened  to  be  made,  a  party  to  or  a  participant  in  any
Proceeding, other than a Proceeding by or in the right of the Company to procure a judgment in its favor. Pursuant to
this Section 3, Indemnitee shall be indemnified against all Expenses and Liabilities actually and reasonably incurred by
Indemnitee  or  on  Indemnitee’s  behalf  in  connection  with  such  Proceeding  or  any  claim,  issue  or  matter  therein,  if
Indemnitee  acted  in  good  faith  and  in  a  manner  Indemnitee  reasonably  believed  to  be  in  or  not  opposed  to  the  best
interests of the Company and, in the case of a criminal proceeding had no reasonable cause to believe that Indemnitee’s
conduct was unlawful.

Section  4.     Indemnity  in  Proceedings  by  or  in  the  Right  of  the  Company .  The  Company  shall  indemnify
Indemnitee in accordance with the provisions of this Section 4 if Indemnitee is, or is threatened to be made, a party to
or a participant in any Proceeding by or in the right of the Company to procure a judgment in its favor. Pursuant to this
Section 4,  Indemnitee  shall  be  indemnified  against  all  Expenses  and  Liabilities  actually  and  reasonably  incurred  by
Indemnitee  or  on  Indemnitee’s  behalf  in  connection  with  such  Proceeding  or  any  claim,  issue  or  matter  therein,  if
Indemnitee  acted  in  good  faith  and  in  a  manner  Indemnitee  reasonably  believed  to  be  in  or  not  opposed  to  the  best
interests of the Company. No indemnification for Expenses or Liabilities shall be made under this Section 4 in respect
of  any  claim,  issue  or  matter  as  to  which  Indemnitee  shall  have  been  finally  adjudged  by  a  court  to  be  liable  to  the
Company, unless and only to the extent that the Delaware Court of Chancery (the “Delaware Court”) or any court in
which the Proceeding was brought shall determine upon application that such indemnification may be made.

Section 5.    Indemnification for Expenses of a Party Who is Wholly or Partly Successful . Notwithstanding any
other provisions of this Agreement, to the extent that Indemnitee is a party to (or a participant in) and is successful, on
the merits or otherwise, in any Proceeding or in defense of any claim, issue or matter therein, in whole or in part, the
Company  shall  indemnify  Indemnitee  against  all  Expenses  actually  and  reasonably  incurred  by  Indemnitee  in
connection  therewith.  If  Indemnitee  is not  wholly  successful  in  such  Proceeding  but  is  successful,  on  the  merits  or
otherwise, as to one or more but less than all claims, issues or matters in such Proceeding, the Company shall indemnify
Indemnitee  against  all  Expenses  actually  and  reasonably  incurred  by  him  or  on  his  behalf  in  connection  with  each
successfully  resolved  claim,  issue  or  matter.  If  the  Indemnitee  is  not  wholly  successful  in  such  Proceeding,  the
Company also shall indemnify Indemnitee against all Expenses reasonably incurred in connection with a claim, issue or
matter related to any claim, issue or matter on which the Indemnitee was successful. For purposes of this Section 5 and
without  limitation,  the  termination  of  any  claim,  issue  or  matter  in  such  a  Proceeding  by  dismissal,  with  or  without
prejudice, shall be deemed to be a successful result as to such claim, issue or matter.

Section  6.    

Indemnification  For  Expenses  of  a  Witness .  Notwithstanding  any  other  provision  of  this
Agreement, to the extent that Indemnitee is, by reason of Indemnitee’s Corporate Status, a witness in any Proceeding to
which Indemnitee is not a party, Indemnitee shall be indemnified against all Expenses actually and reasonably incurred
by Indemnitee or on Indemnitee’s behalf in connection therewith.

Section 7.    Additional Indemnification.

(a)    Notwithstanding any limitation in Section 3, Section 4, Section 5 or Section 6, the Company shall
indemnify Indemnitee to the fullest extent permitted by law if Indemnitee is a party to or threatened to be made a party
to any Proceeding (including a Proceeding by or in the right of the Company to procure a judgment in its favor) against
all reasonable Expenses and Liabilities actually incurred by Indemnitee in connection with the Proceeding.

(b)     For  purposes  of  Section 7(a), the meaning of the phrase “to the fullest extent permitted by law”

shall include, but not be limited to:

(i)    to the fullest extent permitted by the provision of the DGCL that authorizes or contemplates
additional  indemnification  by  agreement,  or  the  corresponding  provision of  any  amendment  to  or  replacement  of  the
DGCL, and

(ii)     to the fullest extent authorized or permitted by any amendments to or replacements of the
DGCL  adopted  after  the  date  of  this Agreement  that  increase  the  extent  to  which  a  corporation  may  indemnify  its
officers and directors.

Section 8.     Exclusions. Notwithstanding any provision in this Agreement, the Company shall not be obligated

under this Agreement to make any indemnity in connection with any claim made against Indemnitee:

(a)    for an accounting of profits made from the purchase and sale (or sale and purchase) by Indemnitee
of securities of the Company within the meaning of Section 16(b) of the Exchange Act or similar provisions of state
statutory law or common law; or

(b)    

in  connection  with  any  Proceeding  (or  any  part  of  any  Proceeding)  initiated  by  Indemnitee,

including any Proceeding (or any part of any Proceeding) initiated by Indemnitee against the Company or its directors,
officers,  employees  or  other  indemnitees,  unless  (i)  the  Board authorized  the  Proceeding  (or  any  part  of  any
Proceeding) prior to its initiation, (ii) the Company provides the indemnification, in its sole discretion, pursuant to the
powers vested in the Company under applicable law or (iii) the Proceeding is one to enforce Indemnitee’s rights under
this Agreement.

Section  9.     Advances  of  Expenses.  Notwithstanding  any  provision  of  this Agreement  to  the  contrary,  the
Company  shall  advance  the  Expenses  incurred  by  Indemnitee  or  on  Indemnitee’s  behalf  in  connection  with  any
Proceeding  within  thirty  (30)  days  after  the  receipt  by  the  Company  of a  statement  or  statements  requesting  such
advances from time to time, whether prior to or after final disposition of any Proceeding. Advances shall be unsecured
and  interest  free. Advances shall be  made  without  regard  to  Indemnitee’s  ability  to  repay  the  Expenses  and  without
regard to Indemnitee’s ultimate entitlement to indemnification under the other provisions of this Agreement.  Advances
shall  include  any  and  all  reasonable  Expenses  incurred  pursuing  an  action  to  enforce  this  right  of  advancement,
including Expenses incurred preparing and forwarding statements to the Company to support the advances claimed. The
Indemnitee shall qualify for advances upon the execution and delivery to the Company of this Agreement which shall
constitute  an  undertaking  providing  that  the  Indemnitee  undertakes  to  repay  the  advance  to  the  extent  that  it  is
ultimately determined that Indemnitee is not entitled to be indemnified by the Company. This Section 9 shall not apply
to any claim made by Indemnitee for which indemnity is excluded pursuant to Section 8.

Section 10.    Procedure for Notification and Defense of Claim .

(a)    To obtain indemnification under this Agreement, Indemnitee shall submit to the Company a written
request,  including  therein  or  therewith  such  documentation  and  information  as  is  reasonably  available  to  Indemnitee
and is reasonably necessary to determine whether and to what extent Indemnitee is entitled to indemnification, not later
than thirty (30) days after receipt by Indemnitee of notice of the commencement of any Proceeding. The omission to
notify the Company will not relieve the Company from any liability which it may have to Indemnitee otherwise than
under  this  Agreement.  The  Secretary  of  the  Company  shall,  promptly  upon  receipt  of  such  a  request  for
indemnification, advise the Board in writing that Indemnitee has requested indemnification.

(b)    The Company will be entitled to participate in the Proceeding at its own expense.

Section 11.    Procedure Upon Application for Indemnification .

(a)     Upon written request by Indemnitee for indemnification pursuant to the first sentence of  Section
10(a), a determination, if required by applicable law, with respect to Indemnitee’s entitlement thereto shall be made in
the  specific  case:  (i)  if  a  Change  in  Control  shall  have  occurred,  by  Independent  Counsel  in  a  written  opinion  to  the
Board, a copy of which shall be delivered to Indemnitee; or (ii) if a Change in Control shall not have occurred, at the
sole discretion of Indemnitee, (A) by a majority vote of the Disinterested Directors, even though less than a quorum of
the Board, (B) by a committee of Disinterested Directors designated by a majority vote of the Disinterested Directors,
even though less than a quorum of the Board, (C) by Independent Counsel in a written opinion to the Board, a copy of
which  shall  be  delivered  to  Indemnitee  or  (D)  by  the  stockholders  of  the  Company;  and,  if  it  is  so  determined  that
Indemnitee  is  entitled  to  indemnification,  payment  to  Indemnitee  shall  be  made  within  ten  (10)  days  after  such
determination. Indemnitee shall cooperate with the person, persons or entity making such determination with respect to
Indemnitee’s  entitlement  to  indemnification,  including  providing  to  such  person,  persons  or  entity  upon  reasonable
advance request any documentation or information which is not privileged or otherwise protected from disclosure and
which is reasonably available to Indemnitee and reasonably necessary to such determination. Any Expenses (including
attorneys’ fees and disbursements) incurred by Indemnitee in so cooperating with the person, persons or entity making
such determination shall be borne by the Company (irrespective of the determination as to Indemnitee’s entitlement to
indemnification) and the Company hereby indemnifies and agrees to hold Indemnitee harmless therefrom.

(b)     In  the  event  the  determination  of  entitlement  to  indemnification  is  to  be  made  by  Independent
Counsel pursuant to Section 11(a) hereof, the Independent Counsel shall be selected as provided in this  Section 11(b).
If  a  Change  in  Control  shall  not  have  occurred,  the  Independent  Counsel  shall  be  selected  by  the  Board,  and  the
Company shall give written notice to Indemnitee advising him of the identity of the Independent Counsel so selected. If
a Change in Control shall have occurred, the Independent Counsel shall be selected by Indemnitee (unless Indemnitee
shall  request  that  such  selection  be  made  by  the  Board,  in  which  event  the  preceding  sentence  shall  apply),  and
Indemnitee shall give written notice to the Company advising it of the identity of the Independent Counsel so selected.
In either event, Indemnitee or the Company, as the case may be, may, within ten (10) days after such written notice of
selection shall have been given, deliver to the Company or to Indemnitee, as the case may be, a written objection to
such  selection;  provided,  however,  that  such  objection  may  be  asserted  only  on  the  ground  that  the  Independent
Counsel  so  selected  does  not  meet  the  requirements  of  “Independent  Counsel”  as  defined  in Section  2  of  this
Agreement, and the objection shall set forth with particularity the factual basis of such assertion. Absent a proper and
timely  objection,  the  person  so  selected  shall  act  as  Independent  Counsel.  If  such  written  objection  is  so  made  and
substantiated,  the  Independent  Counsel  so  selected  may  not  serve  as  Independent  Counsel  unless  and  until  such

objection is withdrawn or a court has determined that such objection is without merit. If, within twenty (20) days after
submission  by  Indemnitee  of  a  written  request  for  indemnification  pursuant  to Section 10(a)  hereof,  no  Independent
Counsel  shall  have  been  selected  and  not  objected  to,  either  the  Company  or  Indemnitee  may  petition  a  court  of
competent jurisdiction for resolution of any objection which shall have been made by the Company or Indemnitee to
the other’s selection of Independent Counsel and/or for the appointment as Independent Counsel of a person selected by
the court or by such other person as the court shall designate, and the person with respect to whom all objections are so
resolved  or  the  person  so  appointed  shall  act  as  Independent  Counsel  under Section  11(a)   hereof.  Upon  the  due
commencement  of  any  judicial  proceeding  or  arbitration  pursuant  to Section  13(a)  of  this Agreement,  Independent
Counsel  shall  be  discharged  and  relieved  of  any  further  responsibility  in  such  capacity  (subject  to  the  applicable
standards of professional conduct then prevailing).

(c)     Notwithstanding anything in this Agreement to the contrary, no determination as to entitlement to
indemnification  under  this Agreement  shall  be  required  to  be  made  prior  to  the  final  disposition  of  the  Proceeding;
provided  that,  in  the  absence  of  any  such  determination  with  respect  to  such  Proceeding,  the  Company  shall  pay  all
Liabilities and advance Expenses with respect to such Proceeding as if the Company had determined the Indemnitee to
be entitled to indemnification and advancement of Expenses with respect to such Proceeding.

Section 12.    Presumptions and Effect of Certain Proceedings .

(a)     In making a determination with respect to entitlement to indemnification hereunder, the person or
persons  or  entity  making  such  determination  shall  presume  that  Indemnitee  is  entitled  to  indemnification  under  this
Agreement. Anyone seeking to overcome this presumption shall have the burden of proof and the burden of persuasion
by clear and convincing evidence in connection with the making by any person, persons or entity of any determination
contrary to that presumption. Neither the failure of the Company (including by its directors or Independent Counsel) to
have made a determination prior to the commencement of any action pursuant to this Agreement that indemnification is
proper in the circumstances because Indemnitee has met the applicable standard of conduct, nor an actual determination
by  the  Company  (including  by  its  directors  or  Independent  Counsel)  that  Indemnitee  has  not  met  such  applicable
standard of conduct, shall be a defense to the action or create a presumption that Indemnitee has not met the applicable
standard of conduct.

(b)     If  the  person,  persons  or  entity  empowered  or  selected  under  Section 11   of  this Agreement  to
determine whether Indemnitee is entitled to indemnification shall not have made a determination within sixty (60) days
after receipt by the Company of the request therefor, the requisite determination of entitlement to indemnification shall
be deemed to have been made and Indemnitee shall be entitled to such indemnification, absent (i) a misstatement by
Indemnitee of a material fact, or an omission of a material fact necessary to make Indemnitee’s statement not materially
misleading,  in  connection  with  the  request  for  indemnification,  or  (ii)  a  prohibition  of  such  indemnification  under
applicable law; provided, however, that such 60-day period may be extended for a reasonable time, not to exceed an
additional  thirty  (30)  days,  if  the  person,  persons  or  entity  making  the  determination  with  respect  to  entitlement  to
indemnification  in  good  faith  requires  such  additional  time  for  the  obtaining  or  evaluating  of  documentation  and/or
information relating thereto; and provided, further, that the foregoing provisions of this Section 12(b) shall not apply (i)
if the determination of entitlement to indemnification is to be made by the stockholders pursuant to Section 11(a)   of
this Agreement and if (A) within fifteen (15) days after receipt by the Company of the request for such determination
the Board has resolved to submit such determination to the stockholders for their consideration at an annual meeting
thereof  to  be  held  within  seventy  five  (75)  days  after  such  receipt  and  such  determination  is  made  thereat,  or  (B)  a
special  meeting  of  stockholders  is  called  within  fifteen  (15)  days  after  such  receipt  for  the  purpose  of  making  such
determination,  such  meeting  is  held  for  such  purpose  within  sixty  (60)  days  after  having  been  so  called  and  such
determination  is  made  thereat,  or  (ii)  if  the  determination  of  entitlement  to  indemnification  is  to  be  made  by
Independent Counsel pursuant to Section 11(a) of this Agreement.

(c)     The  termination  of  any  Proceeding  or  of  any  claim,  issue  or  matter  therein,  by  judgment,  order,
settlement or conviction, or upon a plea of nolo contendere  or  its  equivalent,  shall not (except as otherwise expressly
provided in this Agreement) of itself adversely affect the right of Indemnitee to indemnification or create a presumption
that Indemnitee did not act in good faith and in a manner which he reasonably believed to be in or not opposed to the
best  interests  of  the  Company  or,  with  respect  to  any  criminal  Proceeding,  that  Indemnitee  had  reasonable  cause  to
believe that his conduct was unlawful. Anyone seeking to overcome this presumption shall have the burden of proof
and the burden of persuasion by clear and convincing evidence.

(d)     Reliance  as  Safe  Harbor.  For  purposes  of  any  determination  of  good  faith,  Indemnitee  shall  be
deemed to have acted in good faith if Indemnitee’s action is based on the records or books of account of the Enterprise,
including  financial  statements,  or  on  information  supplied  to  Indemnitee  by  the  officers,  directors,  managers,
employees, agents or representatives of the Enterprise in the course of their duties, or on the advice of legal counsel for
the Enterprise or on information or records given or reports made to the Enterprise by an independent certified public
accountant or by an appraiser or other expert selected with the reasonable care by the Enterprise. The provisions of this
Section  12(d)  shall  not  be  deemed  to  be  exclusive  or  to  limit  in  any  way  the  other  circumstances  in  which  the

Indemnitee may be deemed to have met the applicable standard of conduct set forth in this Agreement.

(e)    Actions of Others. The knowledge and/or actions, or failure to act, of any director, officer, agent or
employee of the Enterprise shall not be imputed to Indemnitee for purposes of determining the right to indemnification
under this Agreement.

Section 13.    Remedies of Indemnitee.

(a)    

In  the  event  that  (i)  a  determination  is  made  pursuant  to  Section  11   of  this  Agreement  that
Indemnitee is not entitled to indemnification under this Agreement, (ii) advancement of Expenses is not timely made
pursuant to Section 9 of this Agreement, (iii) no determination of entitlement to indemnification shall have been made
pursuant to Section 11(a) of this Agreement within forty-five (45) days after receipt by the Company of the request for
indemnification, (iv) payment of indemnification is not made pursuant to Section 5 or Section 6 or the last sentence of
Section 11(a) of this Agreement within ten (10) days after receipt by the Company of a written request therefor, or (v)
payment of indemnification pursuant to Section 3, Section 4 or Section 7 of this Agreement is not made within ten (10)
days after a determination has been made that Indemnitee is entitled to indemnification, Indemnitee shall be entitled to
an  adjudication  by  a  court  of  his  entitlement  to  such  indemnification  or  advancement  of  Expenses.  Alternatively,
Indemnitee,  at  his  option,  may  seek  an  award  in  arbitration  to  be  conducted  by  a  single  arbitrator  pursuant  to  the
Commercial Arbitration Rules of the American Arbitration Association. Indemnitee shall commence such proceeding
seeking an adjudication or an award in arbitration within one hundred eighty (180) days following the date on which
Indemnitee first has the right to commence such proceeding pursuant to this Section 13(a); provided, however, that the
foregoing clause shall not apply in respect of a proceeding brought by Indemnitee to enforce his rights under Section 5
of  this  Agreement.  The  Company  shall  not  oppose  Indemnitee’s  right  to  seek  any  such  adjudication  or  award  in
arbitration.

(b)    In the event that a determination shall have been made pursuant to  Section 11(a) of this Agreement
that  Indemnitee  is  not  entitled  to  indemnification,  any  judicial  proceeding  or  arbitration  commenced  pursuant  to  this
Section 13 shall be conducted in all respects as a de novo trial, or arbitration, on the merits and Indemnitee shall not be
prejudiced  by  reason  of  that  adverse  determination.  In  any  judicial  proceeding  or  arbitration  commenced  pursuant  to
this Section  13  the  Company  shall  have  the  burden  of  proving  Indemnitee  is  not  entitled  to  indemnification  or
advancement of Expenses, as the case may be.

(c)    

If  a  determination  shall  have  been  made  pursuant  to  Section  11(a)   of  this  Agreement  that
Indemnitee  is  entitled  to  indemnification,  the  Company  shall  be  bound  by  such  determination  in  any  judicial
proceeding or arbitration commenced pursuant to this Section 13, absent (i) a misstatement by Indemnitee of a material
fact,  or  an  omission  of  a  material  fact  necessary  to  make  Indemnitee’s  statement  not  materially  misleading,  in
connection with the request for indemnification, or (ii) a prohibition of such indemnification under applicable law.

(d)     The  Company  shall  be  precluded  from  asserting  in  any  judicial  proceeding  or  arbitration
commenced pursuant to this Section 13 that the procedures and presumptions of this such arbitrator that the Company
is bound by all the provisions of this Agreement are not valid, binding and enforceable and shall stipulate in any such
court or before any such arbitrator that the Company is bound by all the provisions of this Agreement.

(e)     The  Company  shall  indemnify  Indemnitee  against  any  and  all  Expenses  and,  if  requested  by
Indemnitee,  shall  (within  ten  (10)  days  after  receipt  by  the  Company  of  a  written  request  therefore)  advance  such
expenses  to  Indemnitee,  which  are  incurred  by  Indemnitee  in  connection  with  any  action  brought  by  Indemnitee  for
indemnification or advance of Expenses from the Company under this Agreement or under any directors’ and officers’
liability insurance policies maintained by the Company, regardless of whether Indemnitee ultimately is determined to
be entitled to such indemnification, advancement of Expenses or insurance recovery, as the case may be.

Section 14.    Non-exclusivity; Survival of Rights; Insurance; Primacy of Indemnification; Subrogation .

(a)     The  rights  of  indemnification  and  to  receive  advancement  of  Expenses  as  provided  by  this
Agreement shall not be deemed exclusive of any other rights to which Indemnitee may at any time be entitled under
applicable law, the Certificate of Incorporation, the Bylaws, any agreement, a vote of stockholders or a resolution of
directors, or otherwise. No amendment, alteration or repeal of this Agreement or of any provision hereof shall limit or
restrict any right of Indemnitee under this Agreement in respect of any action taken or omitted by such Indemnitee in
his  Corporate  Status  prior  to  such  amendment,  alteration  or  repeal.  To  the  extent  that  a  change  in  Delaware  law,
whether  by  statute  or  judicial  decision,  permits  greater  indemnification  or  advancement  of  Expenses  than  would  be
afforded currently under the Bylaws and this Agreement, it is the intent of the parties hereto that Indemnitee shall enjoy
by this Agreement the greater benefits so afforded by such change. No right or remedy herein conferred is intended to
be  exclusive  of  any  other  right  or  remedy,  and  every  other  right  and  remedy  shall  be  cumulative  and  in  addition  to
every  other  right  and  remedy  given  hereunder  or  now  or  hereafter  existing  at  law  or  in  equity  or  otherwise.  The
assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or

employment of any other right or remedy.

(b)     The  Company  shall,  if  commercially  reasonable,  obtain  and  maintain  in  effect  during  the  entire
period  for  which  the  Company  is  obligated  to  indemnify  Indemnitee  under  this Agreement,  one  or  more  policies  of
insurance with reputable insurance companies to provide the directors and officers of the Company with coverage for
losses from wrongful acts and omissions and to ensure the Company’s performance of its indemnification obligations
under this Agreement. Indemnitee shall be covered by such policy or policies in accordance with its or their terms to the
maximum  extent  of  the  coverage  available  for  any  such  director,  officer,  employee  or  agent  under  such  policy  or
policies. In all such policies, Indemnitee shall be named as an insured in such a manner as to provide Indemnitee with
the same rights and benefits as are accorded to the most favorably insured of the Company’s directors and officers. At
the time of the receipt of a notice of a claim pursuant to the terms hereof, the Company shall give prompt notice of the
commencement of such proceeding to the insurers in accordance with the procedures set forth in the respective policies.
The  Company  shall  thereafter  take  all  necessary  or  desirable  action  to  cause  such  insurers  to  pay,  on  behalf of  the
Indemnitee, all amounts payable as a result of such proceeding in accordance with the terms of such policies.

(c)     The Company hereby acknowledges that Indemnitee may have certain rights to indemnification,
advancement  of  expenses  and/or  insurance  provided  by  the  Pioneer  Stockholder  and  certain  of  the  Pioneer
Stockholder’s affiliates that, directly or indirectly, (i) are controlled by, (ii) control or (iii) are under common control
with, the Pioneer Stockholder (collectively, the “Pioneer Indemnitors”). The Company hereby agrees (i) that it is the
indemnitor of first resort (i.e., its obligations to Indemnitee are primary and any obligation of the Pioneer Indemnitors
to  advance  Expenses  or  to provide  indemnification  for  the  same  Liabilities  or  Expenses  incurred  by  Indemnitee  is
secondary),  (ii)  that  it  shall  be  required  to  advance  the  full  amount  of  Expenses  actually  incurred  by  Indemnitee  and
shall be liable for the full amount of all Liabilities and Expenses as required by the terms of this Agreement and the
Certificate of Incorporation or Bylaws (or any other agreement between the Company and Indemnitee), without regard
to any rights Indemnitee may have against the Pioneer Indemnitors, and (iii) that it irrevocably waives, relinquishes and
releases the Pioneer Indemnitors from any and all claims against the Pioneer Indemnitors for contribution, subrogation
or any other recovery of any kind in respect thereof. The Company further agrees that no advancement or payment by
the  Pioneer  Indemnitors  on  behalf  of  Indemnitee  with  respect  to  any  claim  for  which  Indemnitee  has  sought
indemnification  from  the  Company  shall  affect  the  foregoing  and  the  Pioneer  Indemnitors  shall  have  a  right  of
contribution  and/or  be  subrogated  to  the  extent  of  such  advancement  or  payment  to  all  of  the  rights  of  recovery  of
Indemnitee against the Company. The Company and Indemnitee agree that the Pioneer Indemnitors are express third
party beneficiaries of the terms of this Section 14(c).

(d)     Except as provided in Section 14(c) above, in the event of any payment under this Agreement, the
Company shall be subrogated to the extent of such payment to all of the rights of recovery of Indemnitee (other than
against  the  Pioneer  Indemnitors),  who  shall  execute  all  papers  required  and  take  all  action  necessary  to  secure  such
rights,  including  execution  of  such  documents  as  are  necessary  to  enable  the  Company  to  bring  suit  to  enforce  such
rights.

(e)     Except as provided in Section 14(c) above, the Company shall not be liable under this Agreement
to make any payment of amounts otherwise indemnifiable (or for which advancement is provided) hereunder if and to
the  extent  that  Indemnitee  has  otherwise  actually  received  such  payment  under  any  insurance  policy,  contract,
agreement or otherwise.

(f)     Except  as  provided  in  Section  14(c)  above,  the  Company’s  obligation  to  indemnify  or  advance
Expenses hereunder to Indemnitee who is or was serving at the request of the Company as a director, officer, employee
or  agent  of  any  other  corporation,  partnership,  joint  venture,  trust,  employee  benefit  plan  or  other  enterprise  shall  be
reduced  by  any  amount  Indemnitee  has  actually  received  as  indemnification  or  advancement  of  expenses  from  such
other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise.

Section 15.     Duration of Agreement . This Agreement shall continue until and terminate upon the later of: (a)
ten (10) years after the date that Indemnitee shall have ceased to serve in any Corporate Status or (b) one (1) year after
the  final  termination  of  any  Proceeding  (including  any  rights  of  appeal  thereto)  in  respect  of  which  Indemnitee  is
granted  rights  of  indemnification  or  advancement  of  Expenses  hereunder  and  of  any  Proceeding  commenced  by
Indemnitee  pursuant  to Section  13  of  this Agreement  relating  thereto  (including  any  rights  of  appeal  thereto).  This
Agreement  shall  be  binding  upon  the  Company  and  its  successors  and  assigns  and  shall  inure  to  the  benefit  of
Indemnitee and his heirs, executors and administrators.

Section 16.    Severability. If any provision or provisions of this Agreement shall be held to be invalid, illegal or
unenforceable for any reason whatsoever: (a) the validity, legality and enforceability of the remaining provisions of this
Agreement (including without limitation, each portion of any Section of this Agreement containing any such provision
held to be invalid, illegal or unenforceable, that is not itself invalid, illegal or unenforceable) shall not in any way be
affected or impaired thereby and shall remain enforceable to the fullest extent permitted by law; (b) such provision or
provisions shall be deemed reformed to the extent necessary to conform to applicable law and to give the maximum

effect  to  the  intent  of  the  parties  hereto;  and  (c)  to  the  fullest  extent  possible,  the  provisions  of  this  Agreement
(including, without limitation, each portion of any Section of this Agreement containing any such provision held to be
invalid, illegal or unenforceable, that is not itself invalid, illegal or unenforceable) shall be construed so as to give effect
to the intent manifested thereby. Without limiting the generality of the foregoing, this Agreement is intended to confer
upon  Indemnitee  indemnification  rights  to  the  fullest  extent  permitted  by  applicable  laws.  In  the  event  any  provision
hereof conflicts with any applicable law, such provision shall be deemed modified, consistent with the aforementioned
intent, to the extent necessary to resolve such conflict.

Section 17.    Enforcement.

(a)     The Company expressly confirms and agrees that it has entered into this Agreement and assumed
the obligations imposed on it hereby in order to induce Indemnitee to serve as a director or officer of the Company, and
the Company acknowledges that Indemnitee is relying upon this Agreement in serving as a director or officer of the
Company.

(b)    Without limiting any of the rights of Indemnitee under the Certificate of Incorporation or Bylaws as
they  may  be  amended  from  time  to  time,  this Agreement  constitutes  the  entire  agreement  between  the  parties  hereto
with  respect  to  the  subject  matter  hereof  and  supersedes  all  prior  agreements  and  understandings,  oral,  written  and
implied, between the parties hereto with respect to the subject matter hereof.

Section 18.    Modification and Waiver . No supplement, modification, waiver or amendment of this Agreement
shall be binding unless executed in writing by the parties thereto. No waiver of any of the provisions of this Agreement
shall be deemed or shall constitute a waiver of any other provisions of this Agreement nor shall any waiver constitute a
continuing waiver.

Section 19.     Notice by Indemnitee. Indemnitee agrees promptly to notify the Company in writing upon being
served  with  any  summons,  citation,  subpoena,  complaint,  indictment,  information  or  other  document  relating  to  any
Proceeding  or  matter  which  may  be  subject  to  indemnification  or  advancement  of  Expenses  covered  hereunder.  The
failure of Indemnitee to so notify the Company shall not relieve the Company of any obligation which it may have to
the Indemnitee under this Agreement or otherwise.

Section 20.     Notices. All notices, requests, demands and other communications under this Agreement shall be
in writing and shall be deemed to have been duly given (a) if delivered by hand and receipted for by the party to whom
said notice or other communication shall have been directed, (b) when sent by confirmed electronic or facsimile if sent
during normal business hours of the recipient, and if not so confirmed, then, on the next business day, (c) if mailed by
certified or registered mail with postage prepaid, on the third business day after the date on which it is so mailed, or (d)
if sent via a nationally recognized overnight courier, specifying next day delivery, with written verification of receipt,
on the next business day after the date on which it is so mailed:

(a)     If to Indemnitee, at the address indicated on the signature page of this Agreement, or such other

address as Indemnitee shall provide to the Company.

(b)    If to the Company to

ProPetro Holding Corp. 
706 S. Midkiff, Bldg. B 
Midland, Texas 79701 
Attn: Mark Howell

or to any other address as may have been furnished to Indemnitee by the Company.

Section  21.     Contribution.  To  the  fullest  extent  permissible  under  applicable  law,  if  the  indemnification
provided  for  in  this  Agreement  is  unavailable  to  Indemnitee  for  any  reason  whatsoever,  the  Company,  in  lieu  of
indemnifying  Indemnitee,  shall  contribute  to  the  amount  incurred  by  Indemnitee,  whether  for  judgments,  fines,
penalties,  excise  taxes,  amounts  paid  or  to  be  paid  in  settlement  and/or  for  Expenses,  in  connection  with  any  claim
relating to an indemnifiable event under this Agreement, in such proportion as is deemed fair and reasonable in light of
all  of  the circumstances  of  such  Proceeding  in  order  to  reflect  (i)  the  relative  benefits  received  by  the  Company  and
Indemnitee as a result of the event(s) and/or transaction(s) giving cause to such Proceeding; and/or (ii) the relative fault
of  the  Company  (and  its  directors,  officers,  employees  and  agents)  and  Indemnitee  in  connection  with  such  event(s)
and/or transaction(s).

Section 22.     Applicable Law and Consent to Jurisdiction . This Agreement and the legal relations among the
parties shall be governed by, and construed and enforced in accordance with, the laws of the State of Delaware, without
regard to its conflict of laws rules. Except with respect to any arbitration commenced by Indemnitee pursuant to Section

13(a) of this Agreement, the Company and Indemnitee hereby irrevocably and unconditionally (i) agree that any action
or proceeding arising out of or in connection with this Agreement shall be brought only in the Delaware Court, and not
in  any  other  state  or  federal  court  in  the  United  States  of America  or  any  court  in  any  other  country,  (ii)  consent  to
submit to the exclusive jurisdiction of the Delaware Court for purposes of any action or proceeding arising out of or in
connection with this Agreement, (iii) appoint, to the extent such party is not otherwise subject to service of process in
the State of Delaware, irrevocably The Corporation Trust Company as its agent in the State of Delaware as such party’s
agent for acceptance of legal process in connection with any such action or proceeding against such party with the same
legal force and validity as if served upon such party personally within the State of Delaware, (iv) waive any objection
to the laying of venue of any such action or proceeding in the Delaware Court, and (v) waive, and agree not to plead or
to make, any claim that any such action or proceeding brought in the Delaware Court has been brought in an improper
or inconvenient forum.

Section 23.     Identical Counterparts. This Agreement  may  be  executed  in  one  or  more  counterparts,  each  of
which  shall  for  all  purposes  be  deemed  to  be  an  original  but  all  of  which together  shall  constitute  one  and  the  same
Agreement. Only one such counterpart signed by the party against whom enforceability is sought needs to be produced
to evidence the existence of this Agreement.

Section 24.     Miscellaneous. Use of the masculine pronoun shall be deemed to include usage of the feminine
pronoun where appropriate. The headings of the paragraphs of this Agreement are inserted for convenience only and
shall not be deemed to constitute part of this Agreement or to affect the construction thereof.

INDEMNIFICATION AGREEMENT

This  Indemnification Agreement  (“ Agreement”)  is  made  as  of  February  26,  2019  by  and  between  ProPetro

Holding Corp., a Delaware corporation (the “Company”), and the undersigned (“Indemnitee”).

RECITALS

WHEREAS,  highly  competent  persons  have  become  more  reluctant  to  serve  publicly-held  corporations  as
directors  or  in  other  capacities  unless  they  are  provided  with  adequate  protection  through  insurance  or  adequate
indemnification against inordinate risks of claims and actions against them arising out of their service to and activities
on behalf of the corporation;

WHEREAS, the Board of Directors of the Company (the “ Board”) has determined that, in order to attract and
retain qualified individuals, the Company will maintain on an ongoing basis, at its sole expense, liability insurance to
protect persons serving the Company and its subsidiaries from certain liabilities;

WHEREAS,  directors,  officers,  and  other  persons  in  service  to  corporations  or  business  enterprises  are  being
increasingly  subjected  to  expensive  and  time-consuming  litigation  relating  to,  among  other  things,  matters  that
traditionally would have been brought only against the Company or business enterprise itself;

WHEREAS, the Company’s certificate of incorporation (the “ Certificate of Incorporation ”) and bylaws (the
“Bylaws”)  require  indemnification  of  the  officers  and  directors  of  the  Company;  Indemnitee  may  also  be  entitled  to
indemnification  pursuant  to  the  General  Corporation  Law  of  the  State  of  Delaware  (“DGCL”);  The  Certificate  of
Incorporation, the Bylaws and the DGCL expressly provide that the indemnification provisions set forth therein are not
exclusive, and thereby contemplate that contracts may be entered into between the Company and its directors, officers
and other persons with respect to indemnification;

WHEREAS,  the  Board  has  determined  that  the  increased  difficulty  in  attracting  and  retaining  qualified
individuals to serve as directors and officers is detrimental to the best interests of the Company’s stockholders and that
the Company should act to assure such persons that there will be increased certainty of such protection in the future;

WHEREAS,  it  is  reasonable,  prudent  and  necessary  for  the  Company  contractually  to  obligate  itself  to
indemnify, and to advance expenses on behalf of, such persons to the fullest extent permitted by applicable law so that
they will serve or continue to serve the Company free from undue concern that they will not be so indemnified;

WHEREAS,  this  Agreement  is  a  supplement  to  and  in  furtherance  of  the  Certificate  of  Incorporation  and
Bylaws and any resolutions adopted pursuant thereto, and shall not be deemed a substitute therefor, nor to diminish or
abrogate any rights of Indemnitee thereunder; and

WHEREAS, Indemnitee does not regard the protection available under the Bylaws and insurance as adequate in
the present circumstances, and may not be willing to serve as an officer or director without adequate protection, and the
Company desires Indemnitee to serve in such capacity; and Indemnitee is willing to serve, continue to serve and to take
on additional service for or on behalf of the Company on the condition that Indemnitee be so indemnified.

NOW, THEREFORE, in consideration of the premises and the covenants contained herein, the Company and

Indemnitee do hereby covenant and agree as follows:

Section  1.

Services  to  the  Company.  Indemnitee  agrees  to  serve  as  a  director  and  officer  of  the
Company. Indemnitee may at any time and for any reason resign from such position (subject to any other contractual
obligation or any obligation imposed by operation of law), in which event the Company shall have no obligation under
this Agreement to continue Indemnitee in such position. This Agreement shall not be deemed an employment contract
between  the  Company  (or  any  of  its  subsidiaries  or  any  Enterprise  (as  defined  below))  and  Indemnitee.  Indemnitee
specifically  acknowledges  that  Indemnitee’s  employment  with  the  Company  (or  any  of  its  subsidiaries  or  any
Enterprise), if any, is at will, and the Indemnitee may be discharged at any time for any reason, with or without cause,
except  as  may  be  otherwise  provided  in  any  written  employment  contract  between  Indemnitee  and  the  Company  (or
any  of  its  subsidiaries  or  any  Enterprise),  other  applicable  formal  severance  policies  duly  adopted  by  the  Board,  or,
with respect to service as a director or officer of the Company, by the Certificate of Incorporation, the Bylaws and the
DGCL. The foregoing notwithstanding, this Agreement shall continue in force after Indemnitee has ceased to serve as a
director or officer of the Company.

“Independent Counsel” shall not include any person who, under the applicable standards of professional conduct then
prevailing, would have a conflict of interest in representing either the Company or Indemnitee in an action to determine
Indemnitee’s  rights  under  this  Agreement.  The  Company  agrees  to  pay  the  reasonable  fees  and  expenses  of  the
Independent  Counsel  referred  to  above  and  to  fully  indemnify  such  counsel  against  any  and  all  Expenses,  claims,
Liabilities and damages arising out of or relating to this Agreement or its engagement pursuant hereto.

Company  or  otherwise  and  whether  of  a  civil,  criminal,  administrative  or  investigative  nature,  in  which  Indemnitee
was, is or will be involved as a party or otherwise by reason of the Corporate Status of Indemnitee, by reason of any
action taken by Indemnitee or of any action or inaction on Indemnitee’s part while acting in such Corporate Status, in
each  case  whether  or  not  serving  in  such  capacity  at  the  time  any  Liability  or  Expense  is  incurred  for  which
indemnification, reimbursement, or advancement of Expenses can be provided under this Agreement. If the Indemnitee
believes in good faith that a given situation may lead to or culminate in the institution of a Proceeding, this shall be
considered a Proceeding under this paragraph.

“not opposed to the best interests of the Company” as referred to in this Agreement.

Section 3.     Indemnity in Third-Party Proceedings . The  Company  shall  indemnify  Indemnitee  in  accordance
with  the  provisions  of  this Section 3  if  Indemnitee  is,  or  is  threatened  to  be  made,  a  party  to  or  a  participant  in  any
Proceeding, other than a Proceeding by or in the right of the Company to procure a judgment in its favor. Pursuant to
this Section 3, Indemnitee shall be indemnified against all Expenses and Liabilities actually and reasonably incurred by

Indemnitee  or  on  Indemnitee’s  behalf  in  connection  with  such  Proceeding  or  any  claim,  issue  or  matter  therein,  if
Indemnitee  acted  in  good  faith  and  in  a  manner  Indemnitee  reasonably  believed  to  be  in  or  not  opposed  to  the  best
interests of the Company and, in the case of a criminal proceeding had no reasonable cause to believe that Indemnitee’s
conduct was unlawful.

Section  4.     Indemnity  in  Proceedings  by  or  in  the  Right  of  the  Company .  The  Company  shall  indemnify
Indemnitee in accordance with the provisions of this Section 4 if Indemnitee is, or is threatened to be made, a party to
or a participant in any Proceeding by or in the right of the Company to procure a judgment in its favor. Pursuant to this
Section 4,  Indemnitee  shall  be  indemnified  against  all  Expenses  and  Liabilities  actually  and  reasonably  incurred  by
Indemnitee  or  on  Indemnitee’s  behalf  in  connection  with  such  Proceeding  or  any  claim,  issue  or  matter  therein,  if
Indemnitee  acted  in  good  faith  and  in  a  manner  Indemnitee  reasonably  believed  to  be  in  or  not  opposed  to  the  best
interests of the Company. No indemnification for Expenses or Liabilities shall be made under this Section 4 in respect
of  any  claim,  issue  or  matter  as  to  which  Indemnitee  shall  have  been  finally  adjudged  by  a  court  to  be  liable  to  the
Company, unless and only to the extent that the Delaware Court of Chancery (the “Delaware Court”) or any court in
which the Proceeding was brought shall determine upon application that such indemnification may be made.

Section 5.    Indemnification for Expenses of a Party Who is Wholly or Partly Successful . Notwithstanding any
other provisions of this Agreement, to the extent that Indemnitee is a party to (or a participant in) and is successful, on
the merits or otherwise, in any Proceeding or in defense of any claim, issue or matter therein, in whole or in part, the
Company  shall  indemnify  Indemnitee  against  all  Expenses  actually  and  reasonably  incurred  by  Indemnitee  in
connection  therewith.  If  Indemnitee  is not  wholly  successful  in  such  Proceeding  but  is  successful,  on  the  merits  or
otherwise, as to one or more but less than all claims, issues or matters in such Proceeding, the Company shall indemnify
Indemnitee  against  all  Expenses  actually  and  reasonably  incurred  by  him  or  on  his  behalf  in  connection  with  each
successfully  resolved  claim,  issue  or  matter.  If  the  Indemnitee  is  not  wholly  successful  in  such  Proceeding,  the
Company also shall indemnify Indemnitee against all Expenses reasonably incurred in connection with a claim, issue or
matter related to any claim, issue or matter on which the Indemnitee was successful. For purposes of this Section 5 and
without  limitation,  the  termination  of  any  claim,  issue  or  matter  in  such  a  Proceeding  by  dismissal,  with  or  without
prejudice, shall be deemed to be a successful result as to such claim, issue or matter.

Section  6.    

Indemnification  For  Expenses  of  a  Witness .  Notwithstanding  any  other  provision  of  this
Agreement, to the extent that Indemnitee is, by reason of Indemnitee’s Corporate Status, a witness in any Proceeding to
which Indemnitee is not a party, Indemnitee shall be indemnified against all Expenses actually and reasonably incurred
by Indemnitee or on Indemnitee’s behalf in connection therewith.

Section 7.    Additional Indemnification.

(a)    Notwithstanding any limitation in Section 3, Section 4, Section 5 or Section 6, the Company shall
indemnify Indemnitee to the fullest extent permitted by law if Indemnitee is a party to or threatened to be made a party
to any Proceeding (including a Proceeding by or in the right of the Company to procure a judgment in its favor) against
all reasonable Expenses and Liabilities actually incurred by Indemnitee in connection with the Proceeding.

(b)     For  purposes  of  Section 7(a), the meaning of the phrase “to the fullest extent permitted by law”

shall include, but not be limited to:

(i)    to the fullest extent permitted by the provision of the DGCL that authorizes or contemplates
additional  indemnification  by  agreement,  or  the  corresponding  provision of  any  amendment  to  or  replacement  of  the
DGCL, and

(ii)     to the fullest extent authorized or permitted by any amendments to or replacements of the
DGCL  adopted  after  the  date  of  this Agreement  that  increase  the  extent  to  which  a  corporation  may  indemnify  its
officers and directors.

Section 8.     Exclusions. Notwithstanding any provision in this Agreement, the Company shall not be obligated

under this Agreement to make any indemnity in connection with any claim made against Indemnitee:

(a)    for an accounting of profits made from the purchase and sale (or sale and purchase) by Indemnitee
of securities of the Company within the meaning of Section 16(b) of the Exchange Act or similar provisions of state
statutory law or common law; or

(b)    

in  connection  with  any  Proceeding  (or  any  part  of  any  Proceeding)  initiated  by  Indemnitee,
including any Proceeding (or any part of any Proceeding) initiated by Indemnitee against the Company or its directors,
officers,  employees  or  other  indemnitees,  unless  (i)  the  Board authorized  the  Proceeding  (or  any  part  of  any
Proceeding) prior to its initiation, (ii) the Company provides the indemnification, in its sole discretion, pursuant to the
powers vested in the Company under applicable law or (iii) the Proceeding is one to enforce Indemnitee’s rights under

this Agreement.

Section  9.     Advances  of  Expenses.  Notwithstanding  any  provision  of  this Agreement  to  the  contrary,  the
Company  shall  advance  the  Expenses  incurred  by  Indemnitee  or  on  Indemnitee’s  behalf  in  connection  with  any
Proceeding  within  thirty  (30)  days  after  the  receipt  by  the  Company  of a  statement  or  statements  requesting  such
advances from time to time, whether prior to or after final disposition of any Proceeding. Advances shall be unsecured
and  interest  free. Advances shall be  made  without  regard  to  Indemnitee’s  ability  to  repay  the  Expenses  and  without
regard to Indemnitee’s ultimate entitlement to indemnification under the other provisions of this Agreement.  Advances
shall  include  any  and  all  reasonable  Expenses  incurred  pursuing  an  action  to  enforce  this  right  of  advancement,
including Expenses incurred preparing and forwarding statements to the Company to support the advances claimed. The
Indemnitee shall qualify for advances upon the execution and delivery to the Company of this Agreement which shall
constitute  an  undertaking  providing  that  the  Indemnitee  undertakes  to  repay  the  advance  to  the  extent  that  it  is
ultimately determined that Indemnitee is not entitled to be indemnified by the Company. This Section 9 shall not apply
to any claim made by Indemnitee for which indemnity is excluded pursuant to Section 8.

Section 10.    Procedure for Notification and Defense of Claim .

(a)    To obtain indemnification under this Agreement, Indemnitee shall submit to the Company a written
request,  including  therein  or  therewith  such  documentation  and  information  as  is  reasonably  available  to  Indemnitee
and is reasonably necessary to determine whether and to what extent Indemnitee is entitled to indemnification, not later
than thirty (30) days after receipt by Indemnitee of notice of the commencement of any Proceeding. The omission to
notify the Company will not relieve the Company from any liability which it may have to Indemnitee otherwise than
under  this  Agreement.  The  Secretary  of  the  Company  shall,  promptly  upon  receipt  of  such  a  request  for
indemnification, advise the Board in writing that Indemnitee has requested indemnification.

(b)    The Company will be entitled to participate in the Proceeding at its own expense.

Section 11.    Procedure Upon Application for Indemnification .

(a)     Upon written request by Indemnitee for indemnification pursuant to the first sentence of  Section
10(a), a determination, if required by applicable law, with respect to Indemnitee’s entitlement thereto shall be made in
the  specific  case:  (i)  if  a  Change  in  Control  shall  have  occurred,  by  Independent  Counsel  in  a  written  opinion  to  the
Board, a copy of which shall be delivered to Indemnitee; or (ii) if a Change in Control shall not have occurred, at the
sole discretion of Indemnitee, (A) by a majority vote of the Disinterested Directors, even though less than a quorum of
the Board, (B) by a committee of Disinterested Directors designated by a majority vote of the Disinterested Directors,
even though less than a quorum of the Board, (C) by Independent Counsel in a written opinion to the Board, a copy of
which  shall  be  delivered  to  Indemnitee  or  (D)  by  the  stockholders  of  the  Company;  and,  if  it  is  so  determined  that
Indemnitee  is  entitled  to  indemnification,  payment  to  Indemnitee  shall  be  made  within  ten  (10)  days  after  such
determination. Indemnitee shall cooperate with the person, persons or entity making such determination with respect to
Indemnitee’s  entitlement  to  indemnification,  including  providing  to  such  person,  persons  or  entity  upon  reasonable
advance request any documentation or information which is not privileged or otherwise protected from disclosure and
which is reasonably available to Indemnitee and reasonably necessary to such determination. Any Expenses (including
attorneys’ fees and disbursements) incurred by Indemnitee in so cooperating with the person, persons or entity making
such determination shall be borne by the Company (irrespective of the determination as to Indemnitee’s entitlement to
indemnification) and the Company hereby indemnifies and agrees to hold Indemnitee harmless therefrom.

(b)     In  the  event  the  determination  of  entitlement  to  indemnification  is  to  be  made  by  Independent
Counsel pursuant to Section 11(a) hereof, the Independent Counsel shall be selected as provided in this  Section 11(b).
If  a  Change  in  Control  shall  not  have  occurred,  the  Independent  Counsel  shall  be  selected  by  the  Board,  and  the
Company shall give written notice to Indemnitee advising him of the identity of the Independent Counsel so selected. If
a Change in Control shall have occurred, the Independent Counsel shall be selected by Indemnitee (unless Indemnitee
shall  request  that  such  selection  be  made  by  the  Board,  in  which  event  the  preceding  sentence  shall  apply),  and
Indemnitee shall give written notice to the Company advising it of the identity of the Independent Counsel so selected.
In either event, Indemnitee or the Company, as the case may be, may, within ten (10) days after such written notice of
selection shall have been given, deliver to the Company or to Indemnitee, as the case may be, a written objection to
such  selection;  provided,  however,  that  such  objection  may  be  asserted  only  on  the  ground  that  the  Independent
Counsel  so  selected  does  not  meet  the  requirements  of  “Independent  Counsel”  as  defined  in Section  2  of  this
Agreement, and the objection shall set forth with particularity the factual basis of such assertion. Absent a proper and
timely  objection,  the  person  so  selected  shall  act  as  Independent  Counsel.  If  such  written  objection  is  so  made  and
substantiated,  the  Independent  Counsel  so  selected  may  not  serve  as  Independent  Counsel  unless  and  until  such
objection is withdrawn or a court has determined that such objection is without merit. If, within twenty (20) days after
submission  by  Indemnitee  of  a  written  request  for  indemnification  pursuant  to Section 10(a)  hereof,  no  Independent
Counsel  shall  have  been  selected  and  not  objected  to,  either  the  Company  or  Indemnitee  may  petition  a  court  of
competent jurisdiction for resolution of any objection which shall have been made by the Company or Indemnitee to

the other’s selection of Independent Counsel and/or for the appointment as Independent Counsel of a person selected by
the court or by such other person as the court shall designate, and the person with respect to whom all objections are so
resolved  or  the  person  so  appointed  shall  act  as  Independent  Counsel  under Section  11(a)   hereof.  Upon  the  due
commencement  of  any  judicial  proceeding  or  arbitration  pursuant  to Section  13(a)  of  this Agreement,  Independent
Counsel  shall  be  discharged  and  relieved  of  any  further  responsibility  in  such  capacity  (subject  to  the  applicable
standards of professional conduct then prevailing).

(c)     Notwithstanding anything in this Agreement to the contrary, no determination as to entitlement to
indemnification  under  this Agreement  shall  be  required  to  be  made  prior  to  the  final  disposition  of  the  Proceeding;
provided  that,  in  the  absence  of  any  such  determination  with  respect  to  such  Proceeding,  the  Company  shall  pay  all
Liabilities and advance Expenses with respect to such Proceeding as if the Company had determined the Indemnitee to
be entitled to indemnification and advancement of Expenses with respect to such Proceeding.

Section 12.    Presumptions and Effect of Certain Proceedings .

(a)     In making a determination with respect to entitlement to indemnification hereunder, the person or
persons  or  entity  making  such  determination  shall  presume  that  Indemnitee  is  entitled  to  indemnification  under  this
Agreement. Anyone seeking to overcome this presumption shall have the burden of proof and the burden of persuasion
by clear and convincing evidence in connection with the making by any person, persons or entity of any determination
contrary to that presumption. Neither the failure of the Company (including by its directors or Independent Counsel) to
have made a determination prior to the commencement of any action pursuant to this Agreement that indemnification is
proper in the circumstances because Indemnitee has met the applicable standard of conduct, nor an actual determination
by  the  Company  (including  by  its  directors  or  Independent  Counsel)  that  Indemnitee  has  not  met  such  applicable
standard of conduct, shall be a defense to the action or create a presumption that Indemnitee has not met the applicable
standard of conduct.

(b)     If  the  person,  persons  or  entity  empowered  or  selected  under  Section 11   of  this Agreement  to
determine whether Indemnitee is entitled to indemnification shall not have made a determination within sixty (60) days
after receipt by the Company of the request therefor, the requisite determination of entitlement to indemnification shall
be deemed to have been made and Indemnitee shall be entitled to such indemnification, absent (i) a misstatement by
Indemnitee of a material fact, or an omission of a material fact necessary to make Indemnitee’s statement not materially
misleading,  in  connection  with  the  request  for  indemnification,  or  (ii)  a  prohibition  of  such  indemnification  under
applicable law; provided, however, that such 60-day period may be extended for a reasonable time, not to exceed an
additional  thirty  (30)  days,  if  the  person,  persons  or  entity  making  the  determination  with  respect  to  entitlement  to
indemnification  in  good  faith  requires  such  additional  time  for  the  obtaining  or  evaluating  of  documentation  and/or
information relating thereto; and provided, further, that the foregoing provisions of this Section 12(b) shall not apply (i)
if the determination of entitlement to indemnification is to be made by the stockholders pursuant to Section 11(a)   of
this Agreement and if (A) within fifteen (15) days after receipt by the Company of the request for such determination
the Board has resolved to submit such determination to the stockholders for their consideration at an annual meeting
thereof  to  be  held  within  seventy  five  (75)  days  after  such  receipt  and  such  determination  is  made  thereat,  or  (B)  a
special  meeting  of  stockholders  is  called  within  fifteen  (15)  days  after  such  receipt  for  the  purpose  of  making  such
determination,  such  meeting  is  held  for  such  purpose  within  sixty  (60)  days  after  having  been  so  called  and  such
determination  is  made  thereat,  or  (ii)  if  the  determination  of  entitlement  to  indemnification  is  to  be  made  by
Independent Counsel pursuant to Section 11(a) of this Agreement.

(c)     The  termination  of  any  Proceeding  or  of  any  claim,  issue  or  matter  therein,  by  judgment,  order,
settlement or conviction, or upon a plea of nolo contendere  or  its  equivalent,  shall not (except as otherwise expressly
provided in this Agreement) of itself adversely affect the right of Indemnitee to indemnification or create a presumption
that Indemnitee did not act in good faith and in a manner which he reasonably believed to be in or not opposed to the
best  interests  of  the  Company  or,  with  respect  to  any  criminal  Proceeding,  that  Indemnitee  had  reasonable  cause  to
believe that his conduct was unlawful. Anyone seeking to overcome this presumption shall have the burden of proof
and the burden of persuasion by clear and convincing evidence.

(d)     Reliance  as  Safe  Harbor.  For  purposes  of  any  determination  of  good  faith,  Indemnitee  shall  be
deemed to have acted in good faith if Indemnitee’s action is based on the records or books of account of the Enterprise,
including  financial  statements,  or  on  information  supplied  to  Indemnitee  by  the  officers,  directors,  managers,
employees, agents or representatives of the Enterprise in the course of their duties, or on the advice of legal counsel for
the Enterprise or on information or records given or reports made to the Enterprise by an independent certified public
accountant or by an appraiser or other expert selected with the reasonable care by the Enterprise. The provisions of this
Section  12(d)  shall  not  be  deemed  to  be  exclusive  or  to  limit  in  any  way  the  other  circumstances  in  which  the
Indemnitee may be deemed to have met the applicable standard of conduct set forth in this Agreement.

(e)    Actions of Others. The knowledge and/or actions, or failure to act, of any director, officer, agent or
employee of the Enterprise shall not be imputed to Indemnitee for purposes of determining the right to indemnification

under this Agreement.

Section 13.    Remedies of Indemnitee.

(a)    

In  the  event  that  (i)  a  determination  is  made  pursuant  to  Section  11   of  this  Agreement  that
Indemnitee is not entitled to indemnification under this Agreement, (ii) advancement of Expenses is not timely made
pursuant to Section 9 of this Agreement, (iii) no determination of entitlement to indemnification shall have been made
pursuant to Section 11(a) of this Agreement within forty-five (45) days after receipt by the Company of the request for
indemnification, (iv) payment of indemnification is not made pursuant to Section 5 or Section 6 or the last sentence of
Section 11(a) of this Agreement within ten (10) days after receipt by the Company of a written request therefor, or (v)
payment of indemnification pursuant to Section 3, Section 4 or Section 7 of this Agreement is not made within ten (10)
days after a determination has been made that Indemnitee is entitled to indemnification, Indemnitee shall be entitled to
an  adjudication  by  a  court  of  his  entitlement  to  such  indemnification  or  advancement  of  Expenses.  Alternatively,
Indemnitee,  at  his  option,  may  seek  an  award  in  arbitration  to  be  conducted  by  a  single  arbitrator  pursuant  to  the
Commercial Arbitration Rules of the American Arbitration Association. Indemnitee shall commence such proceeding
seeking an adjudication or an award in arbitration within one hundred eighty (180) days following the date on which
Indemnitee first has the right to commence such proceeding pursuant to this Section 13(a); provided, however, that the
foregoing clause shall not apply in respect of a proceeding brought by Indemnitee to enforce his rights under Section 5
of  this  Agreement.  The  Company  shall  not  oppose  Indemnitee’s  right  to  seek  any  such  adjudication  or  award  in
arbitration.

(b)    In the event that a determination shall have been made pursuant to  Section 11(a) of this Agreement
that  Indemnitee  is  not  entitled  to  indemnification,  any  judicial  proceeding  or  arbitration  commenced  pursuant  to  this
Section 13 shall be conducted in all respects as a de novo trial, or arbitration, on the merits and Indemnitee shall not be
prejudiced  by  reason  of  that  adverse  determination.  In  any  judicial  proceeding  or  arbitration  commenced  pursuant  to
this Section  13  the  Company  shall  have  the  burden  of  proving  Indemnitee  is  not  entitled  to  indemnification  or
advancement of Expenses, as the case may be.

(c)    

If  a  determination  shall  have  been  made  pursuant  to  Section  11(a)   of  this  Agreement  that
Indemnitee  is  entitled  to  indemnification,  the  Company  shall  be  bound  by  such  determination  in  any  judicial
proceeding or arbitration commenced pursuant to this Section 13, absent (i) a misstatement by Indemnitee of a material
fact,  or  an  omission  of  a  material  fact  necessary  to  make  Indemnitee’s  statement  not  materially  misleading,  in
connection with the request for indemnification, or (ii) a prohibition of such indemnification under applicable law.

(d)     The  Company  shall  be  precluded  from  asserting  in  any  judicial  proceeding  or  arbitration
commenced pursuant to this Section 13 that the procedures and presumptions of this Agreement are not valid, binding
and enforceable and shall stipulate in any such court or before any such arbitrator that the Company is bound by all the
provisions of this Agreement.

(e)     The  Company  shall  indemnify  Indemnitee  against  any  and  all  Expenses  and,  if  requested  by
Indemnitee,  shall  (within  ten  (10)  days  after  receipt  by  the  Company  of  a  written  request  therefor)  advance  such
expenses  to  Indemnitee,  which  are  incurred  by  Indemnitee  in  connection  with  any  action  brought  by  Indemnitee  for
indemnification  or  advancement  of  Expenses  from  the  Company  under  this Agreement  or  under  any  directors’  and
officers’  liability  insurance  policies  maintained  by  the  Company,  regardless  of  whether  Indemnitee  ultimately  is
determined to be entitled to such indemnification, advancement of Expenses or insurance recovery, as the case may be.

Section 14.    Non-exclusivity; Survival of Rights; Insurance; Subrogation .

(a)     The  rights  of  indemnification  and  to  receive  advancement  of  Expenses  as  provided  by  this
Agreement shall not be deemed exclusive of any other rights to which Indemnitee may at any time be entitled under
applicable law, the Certificate of Incorporation, the Bylaws, any agreement, a vote of stockholders or a resolution of
directors, or otherwise. No amendment, alteration or repeal of this Agreement or of any provision hereof shall limit or
restrict any right of Indemnitee under this Agreement in respect of any action taken or omitted by such Indemnitee in
his  Corporate  Status  prior  to  such  amendment,  alteration  or  repeal.  To  the  extent  that  a  change  in  Delaware  law,
whether  by  statute  or  judicial  decision,  permits  greater  indemnification  or  advancement  of  Expenses  than  would  be
afforded currently under the Bylaws and this Agreement, it is the intent of the parties hereto that Indemnitee shall enjoy
by this Agreement the greater benefits so afforded by such change. No right or remedy herein conferred is intended to
be  exclusive  of  any  other  right  or  remedy,  and  every  other  right  and  remedy  shall  be  cumulative  and  in  addition  to
every  other  right  and  remedy  given  hereunder  or  now  or  hereafter  existing  at  law  or  in  equity  or  otherwise.  The
assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or
employment of any other right or remedy.

(b)     The  Company  shall,  if  commercially  reasonable,  obtain  and  maintain  in  effect  during  the  entire
period  for  which  the  Company  is  obligated  to  indemnify  Indemnitee  under  this Agreement,  one  or  more  policies  of

insurance with reputable insurance companies to provide the directors and officers of the Company with coverage for
losses from wrongful acts and omissions and to ensure the Company’s performance of its indemnification obligations
under this Agreement. Indemnitee shall be covered by such policy or policies in accordance with its or their terms to the
maximum  extent  of  the  coverage  available  for  any  such  director,  officer,  employee  or  agent  under  such  policy  or
policies. In all such policies, Indemnitee shall be named as an insured in such a manner as to provide Indemnitee with
the same rights and benefits as are accorded to the most favorably insured of the Company’s directors and officers. At
the time of the receipt of a notice of a claim pursuant to the terms hereof, the Company shall give prompt notice of the
commencement of such proceeding to the insurers in accordance with the procedures set forth in the respective policies.
The  Company  shall  thereafter  take  all  necessary  or  desirable  action  to  cause  such  insurers  to  pay,  on  behalf of  the
Indemnitee, all amounts payable as a result of such proceeding in accordance with the terms of such policies.

(c)     In the event of any payment under this Agreement, the Company shall be subrogated to the extent
of such payment to all of the rights of recovery of Indemnitee, who shall execute all papers required and take all action
necessary to secure such rights, including execution of such documents as are necessary to enable the Company to bring
suit to enforce such rights.

(d)    The Company shall not be liable under this Agreement to make any payment of amounts otherwise
indemnifiable  (or  for  which  advancement  is  provided)  hereunder  if  and  to  the  extent  that  Indemnitee  has  otherwise
actually received such payment under any insurance policy, contract, agreement or otherwise.

(e)     The Company’s obligation to indemnify or advance Expenses hereunder to Indemnitee who is or
was  serving  at  the  request  of  the  Company  as  a  director,  officer,  employee  or  agent  of  any  other  corporation,
partnership, joint venture, trust, employee benefit plan or other enterprise shall be reduced by any amount Indemnitee
has  actually  received  as  indemnification  or  advancement  of  expenses  from  such  other  corporation,  partnership,  joint
venture, trust, employee benefit plan or other enterprise.

Section 15.     Duration of Agreement . This Agreement shall continue until and terminate upon the later of: (a)
ten (10) years after the date that Indemnitee shall have ceased to serve in any Corporate Status or (b) one (1) year after
the  final  termination  of  any  Proceeding  (including  any  rights  of  appeal  thereto)  in  respect  of  which  Indemnitee  is
granted  rights  of  indemnification  or  advancement  of  Expenses  hereunder  and  of  any  Proceeding  commenced  by
Indemnitee  pursuant  to Section  13  of  this Agreement  relating  thereto  (including  any  rights  of  appeal  thereto).  This
Agreement  shall  be  binding  upon  the  Company  and  its  successors  and  assigns  and  shall  inure  to  the  benefit  of
Indemnitee and his heirs, executors and administrators.

Section 16.    Severability. If any provision or provisions of this Agreement shall be held to be invalid, illegal or
unenforceable for any reason whatsoever: (a) the validity, legality and enforceability of the remaining provisions of this
Agreement (including without limitation, each portion of any Section of this Agreement containing any such provision
held to be invalid, illegal or unenforceable, that is not itself invalid, illegal or unenforceable) shall not in any way be
affected or impaired thereby and shall remain enforceable to the fullest extent permitted by law; (b) such provision or
provisions shall be deemed reformed to the extent necessary to conform to applicable law and to give the maximum
effect  to  the  intent  of  the  parties  hereto;  and  (c)  to  the  fullest  extent  possible,  the  provisions  of  this  Agreement
(including, without limitation, each portion of any Section of this Agreement containing any such provision held to be
invalid, illegal or unenforceable, that is not itself invalid, illegal or unenforceable) shall be construed so as to give effect
to the intent manifested thereby. Without limiting the generality of the foregoing, this Agreement is intended to confer
upon  Indemnitee  indemnification  rights  to  the  fullest  extent  permitted  by  applicable  laws.  In  the  event  any  provision
hereof conflicts with any applicable law, such provision shall be deemed modified, consistent with the aforementioned
intent, to the extent necessary to resolve such conflict.

Section 17.    Enforcement.

(a)     The Company expressly confirms and agrees that it has entered into this Agreement and assumed
the obligations imposed on it hereby in order to induce Indemnitee to serve as a director or officer of the Company, and
the Company acknowledges that Indemnitee is relying upon this Agreement in serving as a director or officer of the
Company.

(b)    Without limiting any of the rights of Indemnitee under the Certificate of Incorporation or Bylaws as
they  may  be  amended  from  time  to  time,  this Agreement  constitutes  the  entire  agreement  between  the  parties  hereto
with  respect  to  the  subject  matter  hereof  and  supersedes  all  prior  agreements  and  understandings,  oral,  written  and
implied, between the parties hereto with respect to the subject matter hereof.

Section 18.    Modification and Waiver . No supplement, modification, waiver or amendment of this Agreement
shall be binding unless executed in writing by the parties hereto. No waiver of any of the provisions of this Agreement
shall be deemed or shall constitute a waiver of any other provisions of this Agreement nor shall any waiver constitute a
continuing waiver.

Section 19.     Notice by Indemnitee. Indemnitee agrees promptly to notify the Company in writing upon being
served  with  any  summons,  citation,  subpoena,  complaint,  indictment,  information  or  other  document  relating  to  any
Proceeding  or  matter  which  may  be  subject  to  indemnification  or  advancement  of  Expenses  covered  hereunder.  The
failure of Indemnitee to so notify the Company shall not relieve the Company of any obligation which it may have to
the Indemnitee under this Agreement or otherwise.

Section 20.     Notices. All notices, requests, demands and other communications under this Agreement shall be
in writing and shall be deemed to have been duly given (a) if delivered by hand and receipted for by the party to whom
said notice or other communication shall have been directed, (b) when sent by confirmed electronic or facsimile if sent
during normal business hours of the recipient, and if not so confirmed, then, on the next business day, (c) if mailed by
certified or registered mail with postage prepaid, on the third business day after the date on which it is so mailed, or (d)
if sent via a nationally recognized overnight courier, specifying next day delivery, with written verification of receipt,
on the next business day after the date on which it is so mailed:

(a)     If to Indemnitee, at the address indicated on the signature page of this Agreement, or such other

address as Indemnitee shall provide to the Company.

(b)    If to the Company to

ProPetro Holding Corp. 
706 S. Midkiff, Bldg. B 
Midland, Texas 79701 
Attn: Mark Howell

or to any other address as may have been furnished to Indemnitee by the Company.

Section  21.     Contribution.  To  the  fullest  extent  permissible  under  applicable  law,  if  the  indemnification
provided  for  in  this  Agreement  is  unavailable  to  Indemnitee  for  any  reason  whatsoever,  the  Company,  in  lieu  of
indemnifying  Indemnitee,  shall  contribute  to  the  amount  incurred  by  Indemnitee,  whether  for  judgments,  fines,
penalties,  excise  taxes,  amounts  paid  or  to  be  paid  in  settlement  and/or  for  Expenses,  in  connection  with  any  claim
relating to an indemnifiable event under this Agreement, in such proportion as is deemed fair and reasonable in light of
all  of  the circumstances  of  such  Proceeding  in  order  to  reflect  (i)  the  relative  benefits  received  by  the  Company  and
Indemnitee as a result of the event(s) and/or transaction(s) giving cause to such Proceeding; and/or (ii) the relative fault
of  the  Company  (and  its  directors,  officers,  employees  and  agents)  and  Indemnitee  in  connection  with  such  event(s)
and/or transaction(s).

Section 22.     Applicable Law and Consent to Jurisdiction . This Agreement and the legal relations among the
parties shall be governed by, and construed and enforced in accordance with, the laws of the State of Delaware, without
regard to its conflict of laws rules. Except with respect to any arbitration commenced by Indemnitee pursuant to Section
13(a) of this Agreement, the Company and Indemnitee hereby irrevocably and unconditionally (i) agree that any action
or proceeding arising out of or in connection with this Agreement shall be brought only in the Delaware Court, and not
in  any  other  state  or  federal  court  in  the  United  States  of America  or  any  court  in  any  other  country,  (ii)  consent  to
submit to the exclusive jurisdiction of the Delaware Court for purposes of any action or proceeding arising out of or in
connection with this Agreement, (iii) appoint, to the extent such party is not otherwise subject to service of process in
the State of Delaware, irrevocably The Corporation Trust Company as its agent in the State of Delaware as such party’s
agent for acceptance of legal process in connection with any such action or proceeding against such party with the same
legal force and validity as if served upon such party personally within the State of Delaware, (iv) waive any objection
to the laying of venue of any such action or proceeding in the Delaware Court, and (v) waive, and agree not to plead or
to make, any claim that any such action or proceeding brought in the Delaware Court has been brought in an improper
or inconvenient forum.

Section 23.     Identical Counterparts. This Agreement  may  be  executed  in  one  or  more  counterparts,  each  of
which  shall  for  all  purposes  be  deemed  to  be  an  original  but  all  of  which together  shall  constitute  one  and  the  same
Agreement. Only one such counterpart signed by the party against whom enforceability is sought needs to be produced
to evidence the existence of this Agreement.

Section 24.     Miscellaneous. Use of the masculine pronoun shall be deemed to include usage of the feminine
pronoun where appropriate. The headings of the paragraphs of this Agreement are inserted for convenience only and
shall not be deemed to constitute part of this Agreement or to affect the construction thereof.
