A set of discovered or prospective oil and/or natural gas accumulations sharing similar geologic, geographic
and  temporal  properties,  such  as  source  rock,  reservoir  structure,  timing,  trapping  mechanism  and
hydrocarbon type.

Refers to the sealing off of fluids in the strata penetrated by a well so that the fluids from one stratum will not
escape into another or to the surface. Regulations of all states require plugging of abandoned wells.

Proved undeveloped.

A well that is found to be capable of producing hydrocarbons in sufficient quantities such that proceeds from
the sale of the production exceed production expenses and taxes.

A  specific  geographic  area  which,  based  on  supporting  geological,  geophysical  or  other  data  and  also
preliminary economic analysis using reasonably anticipated prices and costs, is deemed to have potential for
the discovery of commercial hydrocarbons.

Reserves that can be expected to be recovered through existing wells with existing equipment and operating

under existing economic and operating conditions.

Proved reserves that are expected to be recovered from new wells on undrilled acreage or from existing wells
where a relatively major expenditure is required for recompletion.

The process of re-entering an existing wellbore that is either producing or not producing and completing new
reservoirs in an attempt to establish or increase existing production.

Reserves  are  estimated  remaining  quantities  of  oil  and  natural  gas  and  related  substances  anticipated  to  be
economically producible, as of a given date, by application of development projects to known accumulations.
In addition, there must exist, or there must be a reasonable expectation that there will exist, the legal right to
produce or a revenue interest in the production, installed means of delivering oil and natural gas or related
substances to the market and all permits and financing required to implement the project. Reserves should not
be  assigned  to  adjacent  reservoirs  isolated  by  major,  potentially  sealing,  faults  until  those  reservoirs  are
penetrated  and  evaluated  as  economically  producible.  Reserves  should  not  be  assigned  to  areas  that  are
clearly  separated  from  a  known  accumulation  by  a  non-productive  reservoir  (i.e.,  absence  of  reservoir,
structurally  low  reservoir  or  negative  test  results).  Such  areas  may  contain  prospective  resources  (i.e.,
potentially recoverable resources from undiscovered accumulations).

A porous and permeable underground formation containing a natural accumulation of producible natural gas
and/or oil that is confined by impermeable rock or water barriers and is separate from other reservoirs.

A set of discovered or prospective oil and/or natural gas accumulations sharing similar geologic, geographic
and  temporal  properties,  such  as  source  rock,  reservoir  structure,  timing,  trapping  mechanism  and
hydrocarbon type.

An interest that gives an owner the right to receive a portion of the resources or revenues without having to
carry any costs of development or operations.

The distance between wells producing from the same reservoir. Spacing is often expressed in terms of acres
(e.g., 40-acre spacing) and is often established by regulatory agencies.

A  formation  with  low  permeability  that  produces  natural  gas  with  very  low  flow  rates  for  long  periods  of
time.

Lease acreage on which wells have not been drilled or completed to a point that would permit the production
of economic quantities of oil and natural gas regardless of whether such acreage contains proved reserves.

Except as noted, in this Annual Report on Form 10-K, we refer to Diamondback, together with its consolidated subsidiaries, as “we,” “us,” “our,”
or  “the  Company”.  This  report  includes  certain  terms  commonly  used  in  the  oil  and  gas  industry,  which  are  defined  above  in  the  “Glossary  of  Oil  and
Natural Gas Terms.”

PART I

ITEM 1. BUSINESS AND PROPERTIES

Overview

We  are  an  independent  oil  and  natural  gas  company  focused  on  the  acquisition,  development,  exploration  and  exploitation  of  unconventional,
onshore  oil  and  natural  gas  reserves  in  the  Permian  Basin  in  West  Texas.  This  basin,  which  is  one  of  the  major  producing  basins  in  the  United  States,  is
characterized  by  an  extensive  production  history,  a  favorable  operating  environment,  mature  infrastructure,  long  reserve  life,  multiple  producing  horizons,
enhanced recovery potential and a large number of operators.

We  began  operations  in  December  2007  with  our  acquisition  of  4,174  net  acres  in  the  Permian  Basin.  At  December  31,  2019,  our  total  acreage
position in the Permian Basin was approximately 455,378 gross (382,337 net) acres, which consisted primarily of approximately 218,138 gross (195,461 net)
acres in the Midland Basin and approximately 196,171 gross (155,296  net)  acres  in  the  Delaware  Basin.  In  addition,  our  publicly  traded  subsidiary  Viper
Energy  Partners  LP,  which  we  refer  to  as  Viper,  owns  mineral  interests  underlying  approximately  814,224 gross acres and 24,304  net  royalty  acres  in  the
Permian Basin and Eagle Ford Shale. Approximately 50% of these net royalty acres are operated by us. We own Viper Energy Partners GP LLC, the general
partner of Viper, which we refer to as Viper’s general partner, and we own approximately 58% of the limited partner interest in Viper. Further, our publicly
traded subsidiary Rattler Midstream Partners LP, which we refer to as Rattler, is focused on ownership, operation, development and acquisition of midstream
infrastructure assets in the Midland and Delaware Basins of the Permian Basin. We own Rattler Midstream GP LLC, the general partner of Rattler, which we
refer to as Rattler’s general partner, and we own approximately 71% of the limited partner interest in Rattler. As of December 31, 2019, Rattler owned and
operated 867 miles of crude oil gathering pipelines, natural gas gathering pipelines and a fully integrated water system on acreage that overlays our seven core
Midland  and  Delaware  Basin  development  areas.  To  facilitate  the  transportation  of  produced  water  and  hydrocarbon  volumes  away  from  the  producing
wellhead to ensuring the efficient operations of a crude oil or natural gas well, Rattler’s midstream infrastructure includes a network of gathering pipelines
that collect and transport crude oil, natural gas and produced water from our operations in the Midland and Delaware Basins.

Our activities are primarily focused on horizontal development of the Spraberry and Wolfcamp formations of the Midland Basin and the Wolfcamp
and Bone Spring formations of the Delaware Basin, both of which are part of the larger Permian Basin in West Texas and New Mexico. The Permian Basin is
characterized by high oil and liquids rich natural gas, multiple vertical and horizontal target horizons, extensive production history, long-lived reserves and
high drilling success rates.

As of December 31, 2019, our estimated proved oil and natural gas reserves were 1,127,575 MBOE (which includes estimated reserves of 88,946
MBOE  attributable  to  the  mineral  interests  owned  by  Viper),  based  on  reserve  reports  prepared  by  Ryder  Scott  Company,  L.P.,  or  Ryder  Scott,  our
independent reserve engineers. Of these reserves, approximately 67% are classified as proved developed producing. Proved undeveloped, or PUD, reserves
included in this estimate are from 477 gross (434 net) horizontal well locations in which we have a working interest, and 22 horizontal wells in which we own
only a mineral interest through our subsidiary, Viper. As of December 31, 2019, our estimated proved reserves were approximately 63% oil, 20% natural gas
liquids and 17% natural gas.

Based on our evaluation of applicable geologic and engineering data, we currently have approximately 12,310 gross (8,141 net) identified economic
potential horizontal drilling locations in multiple horizons on our acreage at an assumed price of approximately $60.00 per Bbl WTI. We intend to continue to
develop our reserves and increase production through development drilling and exploitation and exploration activities on this multi-year project inventory of
identified potential drilling locations and through additional acquisitions that meet our strategic and financial objectives, targeting oil-weighted reserves.

Significant 2019 Transactions

Divestiture of Certain Conventional and Non-Core Assets Acquired from Energen

On May 23, 2019, we completed our divestiture of 6,589 net acres of certain non-core Permian assets, which we acquired in our November 2018

merger with Energen Corporation, which we refer to as the Energen merger, for an aggregate sale price of $37 million.

Table of Contents

On July 1, 2019, we completed our divestiture of 103,750 net acres of certain conventional and non-core Permian assets, which we acquired in the

Energen merger, for an aggregate sale price of $285 million.

Drop-Down

On October 1, 2019, we completed a transaction to divest certain mineral and royalty interests to Viper for approximately 18.3 million  of  Viper’s
newly-issued Class B units, approximately 18.3 million newly-issued units of Viper LLC with a fair value of $497 million and $190 million  in  cash,  after
giving effect to closing adjustments for net title benefits, which we refer to as the Drop-Down. The mineral and royalty interests divested in the Drop-Down
represent approximately 5,490 net royalty acres across the Midland and Delaware Basins, of which over 95% are operated by us, and have an average net
royalty interest of approximately 3.2%.

Rattler’s Initial Public Offering

In May 2019, Rattler completed its initial public offering, which we refer to as the Rattler Offering, of an aggregate 43,700,000 common units at a
price  to  the  public  of  $17.50  per  share,  which  common  units  are  traded  on  the  Nasdaq  Global  Select  Market  under  the  symbol  “RTLR.”  Rattler  received
aggregate net proceeds of approximately $720 million from the sale of these common units, after deducting the underwriting discount and offering expenses.

Our Business Strategy

Our business strategy is to continue to profitably grow our business through the following:

• Grow  production  and  reserves  by  developing  our  oil-rich  resource  base.  We  intend  to  drill  and  develop  our  acreage  base  in  an  effort  to
maximize its value and resource potential. Through the conversion of our undeveloped reserves to developed reserves, we will seek to increase
our production, reserves and cash flow while generating favorable returns on invested capital.

•

Focus on increasing hydrocarbon recovery through horizontal development of stacked horizons. We have been developing multiple pay
intervals in the Permian Basin through horizontal drilling and believe that there are opportunities to target additional intervals throughout the
stratigraphic column. Our initial horizontal wells were completed in 2012, and since then we have been an active horizontal driller in the basin.
We believe that our significant experience drilling, completing and operating horizontal wells will allow us to efficiently develop our remaining
inventory and ultimately target other horizons that have limited development to date. The following table presents horizontal wells in which we
have an interest in as of December 31, 2019:

Leverage our experience operating in the Permian Basin. Our executive team, which has an average of over 25 years of industry experience
per person and significant experience in the Permian Basin, intends to continue to seek ways to maximize hydrocarbon recovery by refining and
enhancing  our  drilling  and  completion  techniques.  Our  focus  on  efficient  drilling  and  completion  techniques  is  an  important  part  of  the
continuous  drilling  program  we  have  planned  for  our  significant  inventory  of  identified  potential  drilling  locations.  We  believe  that  the
experience of our executive team in deviated and horizontal drilling and completions has helped reduce the execution risk normally associated
with  these  complex  well  paths.  In  addition,  our  completion  techniques  are  continually  evolving  as  we  evaluate  and  implement  hydraulic
fracturing  practices  that  have  and  are  expected  to  continue  to  increase  recovery  and  reduce  completion  costs.  Our  executive  team  regularly
evaluates our operating results against those of other operators in the area in an effort to benchmark our performance against the best performing
operators and evaluate and adopt best practices.

Enhance returns through our low cost development strategy of resource conversion, capital allocation and continued improvements in
operational and cost efficiencies. Our acreage position is generally in contiguous blocks which allows us to develop this acreage efficiently
with a “manufacturing” strategy that takes advantage of economies of scale and uses centralized production and fluid handling facilities. We are
the  operator  of  approximately  97%  of  our  acreage.  This  operational  control  allows  us  to  manage  more  efficiently  the  pace  of  development
activities  and  the  gathering  and  marketing  of  our  production  and  control  operating  costs  and  technical  applications,  including  horizontal
development.  Our  average  84%  working  interest  in  our  acreage  allows  us  to  realize  the  majority  of  the  benefits  of  these  activities  and  cost
efficiencies.

Pursue strategic acquisitions with substantial resource potential. We have a proven history of acquiring leasehold positions in the Permian
Basin that have substantial oil-weighted resource potential. Our executive team, with its extensive experience in the Permian Basin, has what we
believe  is  a  competitive  advantage  in  identifying  acquisition  targets  and  a  proven  ability  to  evaluate  resource  potential.  We  regularly  review
acquisition opportunities and intend to pursue acquisitions that meet our strategic and financial targets.

• Maintain financial flexibility. We seek to maintain a conservative financial position. As of December 31, 2019, our borrowing base was set at
$2.0 billion and we had $1.99 billion available for borrowing. As of December 31, 2019, Viper LLC had $97 million in outstanding borrowings,
and  $678  million  available  for  borrowing,  under  its  revolving  credit  facility.  As  of  December  31,  2019,  Rattler  LLC  had  $424  million  in
outstanding borrowings, and $176 million available for borrowing, under its revolving credit facility.

Our Strengths

We believe that the following strengths will help us achieve our business goals:

• Oil rich resource base in one of North America’s leading resource plays. All of our leasehold acreage is located in one of the most prolific
oil  plays  in  North  America,  the  Permian  Basin  in  West  Texas.  The  majority  of  our  current  properties  are  well  positioned  in  the  core  of  the
Permian Basin. Our production for the year ended December 31, 2019 was approximately 66% oil, 18% natural gas liquids and 16% natural gas.
As of December 31, 2019, our

3

 
 
 
Table of Contents

estimated net proved reserves were comprised of approximately 63% oil, 20% natural gas liquids and 17% natural gas.

• Multi-year drilling inventory in one of North America’s leading oil resource plays. We have identified a multi-year inventory of potential
drilling  locations  for  our  oil-weighted  reserves  that  we  believe  provides  attractive  growth  and  return  opportunities.  At  an  assumed  price  of
approximately $60.00 per Bbl WTI, we currently have approximately 12,310 gross (8,141 net) identified economic potential horizontal drilling
locations  on  our  acreage  based  on  our  evaluation  of  applicable  geologic  and  engineering  data.  These  gross  identified  economic  potential
horizontal locations have an average lateral length of approximately 7,975 feet, with the actual length depending on lease geometry and other
considerations. These locations exist across most of our acreage blocks and in multiple horizons. The ultimate inter-well spacing may vary from
these distances due to different factors, which would result in a higher or lower location count. In addition, we have approximately 3,413 square
miles of proprietary 3-D seismic data covering our acreage. This data facilitates the evaluation of our existing drilling inventory and provides
insight into future development activity, including additional horizontal drilling opportunities and strategic leasehold acquisitions.

Favorable  operating  environment.  We  have  focused  our  drilling  and  development  operations  in  the  Permian  Basin,  one  of  the  longest
operating hydrocarbon basins in the United States, with a long and well-established production history and developed infrastructure. We believe
that the geological and regulatory environment of the Permian Basin is more stable and predictable, and that we are faced with less operational
risks in the Permian Basin as compared to emerging hydrocarbon basins.

• High degree of operational control. We are the operator of approximately 97% of our Permian Basin acreage. This operating control allows us
to better execute on our strategies of enhancing returns through operational and cost efficiencies and increasing ultimate hydrocarbon recovery
by seeking to continually improve our drilling techniques, completion methodologies and reservoir evaluation processes. Additionally, as the
operator of substantially all of our acreage, we retain the ability to increase or decrease our capital expenditure program based on commodity
price outlooks. This operating control also enables us to obtain data needed for efficient exploration of horizontal prospects.

•

Access to Midstream Infrastructure and Gathering and Transportation Pipelines. Through our publicly traded subsidiary Rattler, we have
secured access to midstream infrastructure and crude oil gathering and transportation pipelines tailored to our expected production growth ramp
in order to allow us the operational flexibility to execute on our growth plan. Rattler is the primary provider of midstream services to us with an
acreage dedication that spans a total of approximately 397,000 gross acres across all of Rattler’s service lines and over the core of the Midland
and Delaware Basins.

Our Properties

Location and Land

Our total acreage position in the Permian Basin was approximately 455,378 gross (382,337 net) acres, which consisted primarily of approximately
218,138 gross (195,461 net) acres in the Midland Basin and approximately 196,171 gross (155,296 net) acres in the Delaware Basin at December 31, 2019.
We are the operator of approximately 97% of this Permian Basin acreage. In addition, our publicly traded subsidiary Viper owns mineral interests underlying
approximately 814,224 gross acres and 24,304 net royalty acres in the Permian Basin and Eagle Ford Shale. Approximately 50% of these net royalty acres are
operated by us.

Further, our subsidiary Rattler is focused on ownership, operation, development and acquisition of the midstream infrastructure assets in the Midland
and Delaware Basins of the Permian Basin. As of December 31, 2019, Rattler owned and operated 867 miles of crude oil gathering pipelines, natural gas
gathering pipelines and a fully integrated water system on acreage that overlays our seven core Midland and Delaware Basin development areas. To facilitate
the transportation of water and hydrocarbon volumes away from the producing wellhead to ensuring the efficient operations of a crude oil or natural gas well,
Rattler’s  midstream  infrastructure  includes  a  network  of  gathering  pipelines  that  collect  and  transport  crude  oil,  natural  gas  and  produced  water  from  our
operations in the Midland and Delaware Basins.

As of December 31, 2019, Rattler also owned (i) a 10% equity interest in EPIC Crude Holdings LP, which is building a long-haul crude oil pipeline
from  the  Permian  Basin  and  the  Eagle  Ford  Shale  to  Corpus  Christi,  Texas  that,  upon  completion,  will  be  capable  of  transporting  approximately  590,000
Bbl/d and, with installation of additional pumps and storage, up to approximately 900,000 Bbl/d, which we refer to as the EPIC pipeline; (ii) a 10% equity
interest in Gray Oak Pipeline, LLC, which is building a long-haul crude oil pipeline that, upon completion, will be capable for transporting 900,000 Bbl/d
from the Permian Basin and the Eagle Ford Shale to points alongside the Texas Gulf Coast, including a marine terminal connection in Corpus Christi, Texas,
which we refer to as the Gray Oak pipeline; (iii) a 4% equity interest in Wink to Webster Pipeline LLC, which is developing a crude oil pipeline that, upon
completion,  will  be  capable  of  transporting  approximately  1,000,000  Bbl/d  from  origin  points  at  Wink  and  Midland  in  the  Permian  Basin  for  delivery  to
multiple Houston area locations, (iv) a 60% equity interest in OMOG JV LLC, a newly formed joint venture entity that acquired Reliance Midstream LLC,
which operates over 230 miles of crude oil gathering and regional transportation pipelines and approximately 200,000 barrels of crude oil storage in Midland,
Martin, Andrews and Ector Counties, Texas, and (v) a 50% equity interest in Amarillo Rattler LLC, which will operate the Yellow Rose gas gathering and
processing system with estimated total capacity of 40,000 Mcf/d and over 84 miles of gathering and regional transportation pipelines in Dawson, Martin and
Andrews Counties, Texas. Each of the Epic and Gray Oak pipelines began interim operations in the second half of 2019, and we expect both to begin full
commercial  operations  in  the  second  quarter  of  2020.  The  Wink  to  Webster  project  is  expected  to  begin  commercial  operations  in  first  half  of  2021.  We
anticipate that the Yellow Rose system will commence full commercial operations in the middle of 2021.

The Permian Basin area covers a significant portion of western Texas and eastern New Mexico and is considered one of the major producing basins

in the United States.

Area History

Our proved reserves are located in the Permian Basin of West Texas, in particular in the Clearfork, Spraberry, Bone Spring, Wolfcamp, Cline, Strawn
and  Atoka  formations.  The  Spraberry  play  was  initiated  with  production  from  several  new  field  discoveries  in  the  late  1940s  and  early  1950s.  It  was
eventually recognized that a regional productive trend was present, as fields were extended and coalesced over a broad area in the central Midland Basin.
Development in the Spraberry play was sporadic over the next several decades due to typically low productive rate wells, with economics being dependent on
oil prices and drilling costs.

The  Wolfcamp  formation  is  a  long-established  reservoir  in  West  Texas,  first  found  in  the  1950s  as  wells  aiming  for  deeper  targets  occasionally
intersected slump blocks or debris flows with good reservoir properties. Exploration using 2-D seismic data located additional fields, but it was not until the
use  of  3-D  seismic  data  in  the  1990s  that  the  greater  extent  of  the  Wolfcamp  formation  was  revealed.  The  additional  potential  of  the  shales  within  this
formation as reservoir rather than just source rocks was not recognized until very recently.

During the late 1990s, Atlantic Richfield Company, or Arco, began a drilling program targeting the base of the Spraberry formation at 10,000 feet,
with an additional 200 to 300 feet drilled to produce from the upper portion of the Wolfcamp formation. Henry Petroleum, a private firm, owned interests in
the Pegasus field in Midland and Upton counties. While drilling in the same area as the Arco project, Henry Petroleum decided to drill completely through the
Wolfcamp section. Henry Petroleum mapped the trend and began acquiring acreage and drilling wells using multiple slick-water fracturing treatments across
the entire Wolfcamp interval. In 2005, former members of Henry Petroleum’s Wolfcamp team formed their own private company, ExL Petroleum, and began
replicating Henry Petroleum’s program. After ExL had drilled 32 productive Wolfcamp/Spraberry wells through late 2007, they monetized a portion of their
acreage position, which led to the acquisition that enabled us to begin our participation in this play. Recent advancements in enhanced recovery techniques
and horizontal drilling continue to make this play attractive to the oil and gas industry. By mid-2010, approximately half of the rigs active in the Permian
Basin were drilling wells in the Wolfberry play. Since then we and most other operators are almost exclusively drilling horizontal wells in the development of
unconventional reservoirs in the Permian Basin. As of December 31, 2019, we held working interests in 2,656 gross (2,202 net) producing wells and only
royalty interests in 4,161 additional wells.

Geology

The  Greater  Permian  Basin  formed  as  an  area  of  rapid  Pennsylvanian-Permian  subsidence  in  response  to  dynamic  structural  influence  of  the
Marathon Uplift and Ancestral Rockies. It is one of the most productive sedimentary basins in the U.S., with established oil and gas production from several
stacked  reservoirs  of  varying  age  ranges,  most  notably  Permian  aged  sediments.  In  particular,  the  Permian  aged  Wolfcamp  and  Spraberry/Bone  Spring
Formations  have  been  heavily  targeted  for  several  decades.  First,  through  vertical  comingling  of  these  zones  and,  more  recently,  through  horizontal
exploitation of each individual horizon. Prior to deposition of Wolfcamp and Spraberry/Bone Spring Formations, the area of the present-day Permian Basin
was a continuous sedimentary feature called the Tabosa Basin. During this time, Ordovician, Silurian, Devonian and Mississippian sediments were laid down
in a primarily open marine, shelf setting. However, some time frames saw more restrictive settings that were conducive to the deposition of organically rich
mudstone such as the Devonian Woodford and Mississippian Barnett/Meramec. These formations are important sources and, more recently, reservoirs within
the present-day Greater Permian Basin.

The Spraberry/Bone Spring was deposited as siliciclastic and carbonate turbidites and debris flows along with pelagic mudstones in a deep-water,
basinal environment, while the Wolfcamp reservoirs consist of debris-flow, grain-flow and fine-grained pelagic sediments, which were also deposited in a
basinal setting. The best carbonate reservoirs within the Wolfcamp and Spraberry/Bone Spring are generally found in close proximity to the Central Basin
Platform,  while  mudstone  reservoirs  thicken  basin-ward,  away  from  the  Central  Basin  Platform.  The  mudstone  within  these  reservoirs  is  organically  rich,
which when buried to sufficient depth for thermal maturation, became the source of the hydrocarbons found both within the mudstones themselves and in the
interbedded conventional clastic and carbonate reservoirs.  Due to this complexity, the Wolfcamp and Spraberry/Bone Spring intervals are a hybrid reservoir
system that contains characteristics of both unconventional and conventional reservoirs.

We  have  successfully  developed  several  hybrid  reservoir  intervals  within  the  Clearfork,  Spraberry/Bone  Spring,  Wolfcamp  and  Barnett/Meramec
formations since we began horizontal drilling in 2012. The mudstones and some clastics exhibit low permeabilities which necessitate the need for hydraulic
fracture stimulation to unlock the vast storage of hydrocarbons in these targets.

We possess, or are in the process of acquiring, 3-D seismic data over substantially all of our major asset areas.  Our extensive geophysical database
currently includes approximately 3,413 square miles of 3-D data.  This data will continue to be utilized in the development of our horizontal drilling program
and identification of additional resource to be exploited.

Production Status

During the year ended December 31, 2019, net production from our Permian Basin acreage was 103,285 MBOE, or an average of 282,972 BOE/d, of

which approximately 66% was oil, 18% was natural gas liquids and 16% was natural gas.

Facilities

Our oil and natural gas processing facilities are typical of those found in the Permian Basin. Our facilities located at well locations include storage

tank batteries, oil/natural gas/water separation equipment and pumping units.

Our  publicly  traded  subsidiary  Rattler  owns  the  Fasken  Center  which  has  over  421,000  net  rentable  square  feet  within  its  two  office  towers  and
associated assets in Midland, Texas. We, Viper and Rattler are headquartered at the Fasken Center. We and unrelated third parties lease office space within the
Fasken Center from Rattler under long-term lease agreements.

We  and  our  subsidiaries  also  own  field  offices  and  related  facilities  in  Midland  and  Reeves  Counties,  Texas.  We  believe  that  these  facilities  are

adequate for our current operations.

Recent and Future Activity

During 2020, we expect to complete an estimated 320 to 360 gross (288 to 324 net) operated horizontal wells on our acreage. We currently estimate
that our capital expenditures in 2020 for drilling and infrastructure will be between $2.8 billion and $3.0 billion, consisting of $2.45 billion to $2.6 billion for
horizontal  drilling  and  completions  including  non-operated  activity,  $200  million  to  $225  million  for  midstream  investments,  excluding  joint  venture
investments, and $150 million to $175 million will be spent on infrastructure and other expenditures, excluding the cost of any leasehold and mineral interest
acquisitions. During the year ended December 31, 2019, we drilled 330 gross (296 net) and completed 317 gross (289 net) operated horizontal wells. During
the year ended December 31, 2019, our capital expenditures for drilling, completing and equipping wells were $2.6 billion. In addition, we spent $364 million
for oil and gas midstream and infrastructure and $776 million for leasehold and mineral rights acquisitions.

We are operating 23 drilling rigs now including two rigs drilling produced water disposal wells and currently intend to operate between 20 and 23
rigs on average in 2020. We will continue monitoring the ongoing commodity price environment and expect to retain the financial flexibility to adjust our
drilling and completion plans in response to market conditions.

With our current development plan, we expect to continue our strong PUD conversion ratio in 2020 by converting an estimated 35% of our PUDs to

a proved developed category, and develop approximately 66% of the consolidated 2019 year-end PUD reserves by the end of 2021.

Oil and Natural Gas Data

Proved Reserves

Evaluation and Review of Reserves

Our historical reserve estimates as of December 31, 2019, 2018 and 2017 were prepared by Ryder Scott with respect to our assets and those of Viper.
Ryder  Scott  is  an  independent  petroleum  engineering  firm.  The  technical  persons  responsible  for  preparing  our  proved  reserve  estimates  meet  the
requirements with regards to qualifications, independence, objectivity and confidentiality set forth in the Standards Pertaining to the Estimating and Auditing
of Oil and Gas Reserves Information promulgated by the Society of Petroleum Engineers. Ryder Scott is a third-party engineering firm and does not own an
interest in any of our properties and is not employed by us on a contingent basis.

Under SEC rules, proved reserves are those quantities of oil and natural gas that, by analysis of geoscience and engineering data, can be estimated
with reasonable certainty to be economically producible from a given date forward, from known reservoirs and under existing economic conditions, operating
methods  and  government  regulations  prior  to  the  time  at  which  contracts  providing  the  right  to  operate  expire,  unless  evidence  indicates  that  renewal  is
reasonably certain, regardless of whether deterministic or probabilistic methods are used for the estimation. If deterministic methods are used, the SEC has
defined reasonable certainty for proved reserves as a “high degree of confidence that the quantities will be recovered.” All of our proved

7

 
 
Table of Contents

reserves as of December 31, 2019 were estimated using a deterministic method. The estimation of reserves involves two distinct determinations. The first
determination results in the estimation of the quantities of recoverable oil and gas and the second determination results in the estimation of the uncertainty
associated  with  those  estimated  quantities  in  accordance  with  the  definitions  established  under  SEC  rules.  The  process  of  estimating  the  quantities  of
recoverable  oil  and  gas  reserves  relies  on  the  use  of  certain  generally  accepted  analytical  procedures.  These  analytical  procedures  fall  into  three  broad
categories  or  methods:  (1)  performance-based  methods,  (2)  volumetric-based  methods  and  (3)  analogy.  These  methods  may  be  used  singularly  or  in
combination  by  the  reserve  evaluator  in  the  process  of  estimating  the  quantities  of  reserves.  The  proved  reserves  for  our  properties  were  estimated  by
performance methods, analogy or a combination of both methods. Approximately 85% of the proved producing reserves attributable to producing wells were
estimated by performance methods. These performance methods include, but may not be limited to, decline curve analysis, which utilized extrapolations of
available  historical  production  and  pressure  data.  The  remaining  15%  of  the  proved  producing  reserves  were  estimated  by  analogy,  or  a  combination  of
performance and analogy methods. The analogy method was used where there were inadequate historical performance data to establish a definitive trend and
where the use of production performance data as a basis for the reserve estimates was considered to be inappropriate. All proved developed non-producing
and undeveloped reserves were estimated by the analogy method.

To  estimate  economically  recoverable  proved  reserves  and  related  future  net  cash  flows,  Ryder  Scott  considered  many  factors  and  assumptions,
including the use of reservoir parameters derived from geological, geophysical and engineering data which cannot be measured directly, economic criteria
based  on  current  costs  and  the  SEC  pricing  requirements  and  forecasts  of  future  production  rates.  To  establish  reasonable  certainty  with  respect  to  our
estimated proved reserves, the technologies and economic data used in the estimation of our proved reserves included production and well test data, downhole
completion information, geologic data, electrical logs, radioactivity logs, core analyses, available seismic data and historical well cost and operating expense
data.

We maintain an internal staff of petroleum engineers and geoscience professionals who worked closely with our independent reserve engineers to
ensure  the  integrity,  accuracy  and  timeliness  of  the  data  used  to  calculate  our  proved  reserves  relating  to  our  assets  in  the  Permian  Basin.  Our  internal
technical team members met with our independent reserve engineers periodically during the period covered by the reserve reports to discuss the assumptions
and methods used in the proved reserve estimation process. We provide historical information to the independent reserve engineers for our properties such as
ownership interest, oil and gas production, well test data, commodity prices and operating and development costs. Our Executive Vice President–Reservoir
Engineering is primarily responsible for overseeing the preparation of all of our reserve estimates. Our Executive Vice President–Reservoir Engineering is a
petroleum engineer with over 30 years of reservoir and operations experience and our geoscience staff has an average of approximately 20 years of industry
experience  per  person.  Our  technical  staff  uses  historical  information  for  our  properties  such  as  ownership  interest,  oil  and  gas  production,  well  test  data,
commodity prices and operating and development costs.

The  preparation  of  our  proved  reserve  estimates  are  completed  in  accordance  with  our  internal  control  procedures.  These  procedures,  which  are

intended to ensure reliability of reserve estimations, include the following:

•

•

•

•

•

•

review and verification of historical production data, which data is based on actual production as reported by us;

preparation of reserve estimates by our Executive Vice President–Reservoir Engineering or under his direct supervision;

review by our Executive Vice President–Reservoir Engineering of all of our reported proved reserves at the close of each quarter, including the
review of all significant reserve changes and all new proved undeveloped reserves additions;

direct reporting responsibilities by our Executive Vice President–Reservoir Engineering to our Chief Executive Officer;

verification of property ownership by our land department; and

no employee’s compensation is tied to the amount of reserves booked.

(1) Estimates  of  reserves  as  of  December  31,  2019, 2018  and  2017  were  prepared  using  an  average  price  equal  to  the  unweighted  arithmetic  average  of
hydrocarbon prices received on a field-by-field basis on the first day of each month within the 12-month periods ended December 31, 2019, 2018 and
2017, respectively, in accordance with SEC guidelines applicable to reserves estimates as of the end of such periods. Reserve estimates do not include
any value for probable or possible reserves that may exist, nor do they include any value for undeveloped acreage. The reserve estimates represent our net
revenue  interest  in  our  properties.  Although  we  believe  these  estimates  are  reasonable,  actual  future  production,  cash  flows,  taxes,  development
expenditures, operating expenses and quantities of recoverable oil and natural gas reserves may vary substantially from these estimates.

The  foregoing  reserves  are  all  located  within  the  continental  United  States.  Reserve  engineering  is  a  subjective  process  of  estimating  volumes  of
economically recoverable oil and natural gas that cannot be measured in an exact manner. The accuracy of any reserve estimate is a function of the quality of
available data and of engineering and geological interpretation. As a result, the estimates of different engineers often vary. In addition, the results of drilling,
testing and production may justify revisions of such estimates. Accordingly, reserve estimates often differ from the quantities of oil and natural gas that are
ultimately  recovered.  Estimates  of  economically  recoverable  oil  and  natural  gas  and  of  future  net  revenues  are  based  on  a  number  of  variables  and
assumptions, all of which may vary from actual results, including geologic interpretation, prices and future production rates and costs. See Item 1A.“Risk
Factors.” We have not filed any estimates of total, proved net oil or natural gas reserves with any federal authority or agency other than the SEC.

Proved Undeveloped Reserves (PUDs)

As  of  December  31,  2019,  our  proved  undeveloped  reserves  totaled  253,820  MBbls  of  oil,  294,051  MMcf  of  natural  gas  and  65,030  MBbls  of

natural gas liquids, for a total of 367,859 MBOE. PUDs will be converted from undeveloped to developed as the applicable wells begin production.

(5,672)

367,859

The increase in proved undeveloped reserves was primarily attributable to extensions of 213,909 MBOE from 291 gross (262 net) wells in which we
have a working interest and 7,591 MBOE from 97 gross wells in which Viper owns royalty interests. Of the 291 gross working interest wells, 64 were in the
Delaware Basin. Transfers of 120,920 MBOE were the result of drilling or participating in 135 gross (119 net) horizontal wells in which we have a working
interest and 79 gross wells in which we have a royalty interest or mineral interest through Viper. We own a working interest in 75 of the 79 gross Viper wells.
Downward revisions of 77,519  MBOE  resulted  from  67,114  MBOE  of  PUD  downgrades  due  to  refinement  of  the  PUD  inventory  following  the  Energen
merger. These downgrades were offset with extensions. The remaining 10,405 MOE of downward revisions were mostly from lower benchmark commodity
prices.

Costs incurred relating to the development of PUDs were approximately $956 million during 2019. Estimated future development costs relating to
the development of PUDs are projected to be approximately $1.2 billion in 2020, $721 million in 2021, $641 million in 2022 and $576 million in 2023. Since
our current executive team assumed management control in 2011, our average drilling costs and drilling times have been reduced. As we continue to develop
our properties and have more well production and completion data, we believe we will continue to realize cost savings and experience lower relative drilling
and completion costs as we convert PUDs into proved developed reserves in upcoming years.

As of December 31, 2019, all of our proved undeveloped reserves are scheduled to be developed within five years from the date they were initially

recorded.

As of December 31, 2019, none of our total proved reserves were classified as proved developed non-producing.

royalty interest in 4,161 additional wells. Through our subsidiary Viper, we own an average unweighted 3.4% royalty or mineral interest in 5,807 productive
wells. Productive wells consist of producing wells and wells capable of production, including natural gas wells awaiting pipeline connections to commence
deliveries and oil wells awaiting connection to production facilities. Gross wells are the total number of producing wells in which we have an interest, and net
wells are the sum of our fractional working interests owned in gross wells.

Drilling Results

The following table sets forth information with respect to the number of wells completed during the periods indicated by basin. Each of these wells
was drilled in the Permian Basin of West Texas. The information should not be considered indicative of future performance, nor should it be assumed that
there is necessarily any correlation between the number of productive wells drilled, quantities of reserves found or economic value. Productive wells are those
that produce commercial quantities of hydrocarbons, whether or not they produce a reasonable rate of return.

(1) Developed acres are acres spaced or assigned to productive wells and do not include undrilled acreage held by production under the terms of the lease.
Large  portions  of  the  acreage  that  are  considered  developed  under  SEC  guidelines  are  developed  with  vertical  wells  or  horizontal  wells  that  are  in  a
single horizon. We believe much of this acreage has significant remaining development potential in one or more intervals with horizontal wells.

(2) Undeveloped acres are acres on which wells have not been drilled or completed to a point that would permit the production of commercial quantities of

oil or natural gas, regardless of whether such acreage contains proved reserves.

(3) Does not include Viper’s mineral interests but does include leasehold acres that we own underlying our mineral interests.
(4) A gross acre is an acre in which a working interest is owned. The number of gross acres is the total number of acres in which a working interest is owned.
(5) A net acre is deemed to exist when the sum of the fractional ownership working interests in gross acres equals one. The number of net acres is the sum of

the fractional working interests owned in gross acres expressed as whole numbers and fractions thereof.

Undeveloped acreage expirations

Many of the leases comprising the undeveloped acreage set forth in the table above will expire at the end of their respective primary terms unless
production from the leasehold acreage has been established prior to such date, in which event the lease will remain in effect until the cessation of production.
The following table sets forth the gross and net undeveloped acreage, as of December 31, 2019, that will expire over the next five years unless production is
established within the spacing units covering the acreage or the lease is renewed or extended under continuous drilling provisions prior to the primary term
expiration dates.

Title to Properties

As  is  customary  in  the  oil  and  natural  gas  industry,  we  initially  conduct  only  a  cursory  review  of  the  title  to  our  properties.  At  such  time  as  we
determine to conduct drilling operations on those properties, we conduct a thorough title examination and perform curative work with respect to significant
defects  prior  to  commencement  of  drilling  operations.  To  the  extent  title  opinions  or  other  investigations  reflect  title  defects  on  those  properties,  we  are
typically responsible for curing any title defects at our expense. We generally will not commence drilling operations on a property until we have cured any
material title defects on such property. We have obtained title opinions on substantially all of our producing properties and believe that we have satisfactory
title  to  our  producing  properties  in  accordance  with  standards  generally  accepted  in  the  oil  and  natural  gas  industry.  Prior  to  completing  an  acquisition  of
producing oil and natural gas leases, we perform title reviews on the most significant leases and, depending on the materiality of properties, we may obtain a
title opinion, obtain an updated title review or opinion or review previously obtained title opinions. Our oil and natural gas properties are subject to customary
royalty and other interests, liens for current taxes and other burdens which we believe do not materially interfere with the use of or affect our carrying value
of the properties.

Marketing and Customers

We typically sell production to a relatively small number of customers, as is customary in the exploration, development and production business. For
the year ended December 31, 2019, three purchasers each accounted for more than 10% of our revenue: Shell Trading (US) Company, which we refer to as
Shell (27%); Plains Marketing, which we refer to as Plains (23%); and Vitol Inc., which we refer to as Vitol (15%). For the year ended December 31, 2018,
three purchasers each accounted for more than 10% of our revenue: Shell Trading (26%); Koch Supply & Trading LP, which we refer to as Koch (15%); and
Occidental Energy Marketing Inc. (11%). For the year ended December 31, 2017, three purchasers each accounted for more than 10% of our revenue: Shell
(31%); Koch (19%); and Enterprise Crude Oil LLC (11%). No other customer accounted for more than 10% of our revenue during these periods. If a major
customer decided to stop purchasing oil and natural gas from us, revenue could decline and our operating results and financial condition could be harmed.

Agreement with Trafigura Trading LLC

We have entered into a firm commitment oil purchase agreement with Trafigura Trading LLC, which we refer to as Trafigura, in which we agreed to
sell and deliver a firm quantity of 25,000 barrels of crude oil per day to Trafigura during the term of the agreement. Under this agreement, which has a seven-
year term beginning on August 1, 2018, the price per barrel of oil paid to us by Trafigura is based on the average of the published settlement quotations for
NYMEX CMA, as adjusted for different delivery methods and periods. If during the term of the agreement we fail to deliver the required quantities of oil for
any month other than for specified force majeure events, we have agreed to pay Trafigura a deficiency payment equal to any unfavorable difference between
the contract price and the spot price, multiplied by the deficiency volume.

Agreement with Plains

In July 2019, our wholly-owned subsidiary, Energen Resources Corporation, which we refer to as Energen Resources, entered into a long-term crude
oil sales agreement with Plains pursuant to which, among other things, our existing agreements with Plains were terminated. Our new agreement with Plains
requires that we make available 50,000 barrels of crude oil per day until the date occurring ten years following the date service commences for ExxonMobil
Oil Corporation, which we refer to as Exxon, pursuant to the transportation service agreement between Exxon and the Wink to Webster pipeline carrier (plus
extensions for force majeure). If during the term of our agreement we fail to deliver the required quantities of oil for any month other than for specified force
majeure events or acts or omissions of Plains, we have agreed to pay Plains a specified per barrel amount, subject to escalation, multiplied by the deficiency
volume.  If  during  the  term  of  the  agreement  we  fail  to  deliver  the  quantities  of  oil  for  any  month  that  we  have  committed  for  such  month  other  than  for
specified force majeure events or acts or omissions of Plains, we have agreed to pay Plains a deficiency payment. We have also dedicated certain crude oil
production attributable to certain of our interests to Plains in connection with this agreement. Pricing for our production under the Plains agreement (i) prior to
the  date  service  commences  for  Exxon  pursuant  to  the  transportation  service  agreement  between  Exxon  and  the  Wink  to  Webster  pipeline  carrier,  is  at  a
Midland WTI or WTL, as applicable, base price less certain costs and (ii) following the date service commences for Exxon pursuant to the transportation
service agreement between Exxon and the Wink to Webster pipeline carrier, for volumes up to 100,000 barrels of crude oil per day, is at a MEH WTI or WTL
base price, as applicable, less certain costs.

Agreement with Shell

In December 2018, we entered into an oil purchase agreement with Shell, which was amended and restated in December 2019, in which Shell agreed
to  transport  crude  oil  it  purchases  from  us  through  the  EPIC  pipeline,  with  which  we  have  an  agreement  for  the  transportation  of  certain  crude  oil.  Our
agreement with Shell provides for different purchase obligations during the pre-commencement and service commencement periods for the EPIC pipeline,
and provides for a three-year term beginning on the service commencement date for the EPIC pipeline. Shell has the option to extend its purchase obligations
for  up  to  three  one-year  terms,  but  not  beyond  March  31,  2026  except  in  the  event  of  force  majeure.  Our  delivery  obligation  (i)  prior  to  the  full  service
commencement of the EPIC pipeline will be, subject to certain conditions, including our right to repurchase certain volumes, either 30,000 or 40,000 barrels
of crude oil per day and (ii) during the full service term will not exceed 50,000 barrels of crude oil per day. In addition, our wholly-owned subsidiary Energen
Resources has signed an agreement with Shell in which all or a portion of the 50,000 barrels of crude oil per day referenced in the previous sentence may also
be satisfied by Energen Resources. During different pre-commencement periods, Shell has agreed to pay us the price per barrel of oil based on the arithmetic
average of the daily settlement price for the “Light Sweet Crude Oil” Prompt Month future contracts reported by the NYMEX over the applicable one-month
period, subject to certain adjustments, plus a Corpus Christi differential determined based on Shell’s average sales price for its WTI barrels in Corpus Christi
less certain other costs, expenses and fees. During the full service term, the price per barrel of oil payable by Shell to us is based on calendar dated Brent
pricing plus a negotiated differential generally based on certain Argus WTI Houston CIF Rotterdam and Platts Midland DAP Rotterdam pricing, less certain
adjustments.

Agreements with Vitol

On October 18, 2018, we entered into an agreement with Vitol to, among other things, sell an average of 23,750 barrels of crude oil per day plus
other  agreed  upon  volumes.  We  are  continuing  to  sell  crude  oil  to  Vitol  on  a  month-to-month  basis  and  expect  to  continue  to  do  so  under  our  existing
agreement  with  Vitol  until  our  new  agreement  with  Vitol  becomes  effective.  Under  our  new  agreement  with  Vitol,  we  agreed  to  sell,  and  Vitol  agreed  to
purchase, (i) subject to certain conditions, including accelerated commissioning service on the Gray Oak pipeline and completion of certain infrastructure
connections, 50,000 barrels of crude oil per day on average during each month occurring during the first seven years of full service on the Gray Oak pipeline,
(ii)  subject  to  certain  conditions  and  the  satisfaction  of  other  conditions,  including  full  service  on  the  Gray  Oak  Pipeline  and  completion  of  certain
infrastructure connections, an additional 50,000 barrels of crude oil per day on average during each month occurring during the first seven years following
satisfaction of such conditions, (iii) subject to certain conditions, including notice that transportation services on the EPIC pipeline are ready to commence
and completion of certain infrastructure connections, an additional 50,000 barrels of crude oil per day on average during each month occurring during the first
seven years following satisfaction of such conditions and (iv) such other volumes of crude oil as agreed by the parties. We are entitled to receive payment for
such crude oil under netback pricing, whereby the price for our crude oil is determined based on a formula which takes into consideration the final purchase
price obtained by Vitol in marketing such crude oil in certain third party transactions less certain costs. In connection therewith, Vitol has agreed to, among
other things, use commercially reasonable efforts to (i) maximize the final purchase price to us and mitigate any costs factored into the price determination
and (ii) acquire third party crude oil to cover any shortfall below our volumes commitments. Vitol also agrees to (i) use the same care and apply the same
policies as it would exercise and apply if it were trading the subject crude oil for Vitol’s own account and (ii) transport such crude oil on certain designated
pipelines,  including  the  Gray  Oak  pipeline  pursuant  to  rights  we  have  obtained  through  our  Gray  Oak  transportation  services  agreement  described  below
under “—Transportation”, under third party shipper rights or term assignments, as applicable, prior to Vitol’s downstream marketing activities.

Competition

The  oil  and  natural  gas  industry  is  intensely  competitive,  and  in  our  upstream  segment,  we  compete  with  other  companies  that  have  greater
resources. Many of these companies not only explore for and produce oil and natural gas, but also carry on midstream and refining operations and market
petroleum  and  other  products  on  a  regional,  national  or  worldwide  basis.  These  companies  may  be  able  to  pay  more  for  productive  oil  and  natural  gas
properties and exploratory prospects or to define, evaluate, bid for and purchase a greater number of properties and prospects than our financial or human
resources permit. In addition, these companies may have a greater ability to continue exploration activities during periods of low oil and natural gas market
prices.  Our  larger  or  more  integrated  competitors  may  be  able  to  absorb  the  burden  of  existing,  and  any  changes  to,  federal,  state  and  local  laws  and
regulations  more  easily  than  we  can,  which  would  adversely  affect  our  competitive  position.  Our  ability  to  acquire  additional  properties  and  to  discover
reserves in the future will be dependent upon our ability to evaluate and select suitable properties and to consummate transactions in a highly competitive
environment.  In  addition,  because  we  have  fewer  financial  and  human  resources  than  many  companies  in  our  industry,  we  may  be  at  a  disadvantage  in
bidding for exploratory prospects and producing oil and natural gas properties. Further, oil and natural gas compete with other forms of energy available to
customers,  primarily  based  on  price.  These  alternate  forms  of  energy  include  electricity,  coal  and  fuel  oils.  Changes  in  the  availability  or  price  of  oil  and
natural gas or other forms of energy, as well as business conditions, conservation, legislation, regulations and the ability to convert to alternate fuels and other
forms of energy may affect the demand for oil and natural gas.

In our midstream operations segment, as Rattler seeks to expand its crude oil, natural gas and water-related midstream services, it faces a high level
of competition, including major integrated crude oil and natural gas companies, interstate and intrastate pipelines and companies that gather, compress, treat,
process, transport, store or market oil and natural gas. As Rattler seeks to expand to provide midstream services to third party producers, it similarly faces a
high  level  of  competition.  Competition  is  often  the  greatest  in  geographic  areas  experiencing  robust  drilling  by  producers  and  during  periods  of  high
commodity prices for crude oil, natural gas or NGLs. Within the acreage dedicated by Rattler to us, Rattler does not compete with other midstream companies
to provide us with midstream services as a result of our relationship and long-term dedications to Rattler’s midstream assets. However, we may continue to
use  third  party  service  providers  for  certain  midstream  services  within  such  dedicated  acreage  until  the  expiration  or  termination  of  certain  pre-existing
dedications.

Transportation

During the initial development of our fields we evaluate all gathering and delivery infrastructure in the areas of our production. Currently, a majority

of our production in the Midland and Delaware Basins are transported to purchasers by pipeline.

We  have  entered  into  multiple  fee-based  commercial  agreements  with  Rattler,  each  with  an  initial  term  ending  in  2034,  utilizing  Rattler’s
infrastructure  assets  or  its  planned  infrastructure  assets  to  provide  an  array  of  essential  services  critical  to  our  upstream  operations  in  the  Delaware  and
Midland Basins. Our agreements with Rattler include a total of approximately 397,000 gross acres across all Rattler’s service lines across the Midland and
Delaware Basins.

We  are  also  party  to  a  transportation  services  agreement  with  Gray  Oak  Pipeline,  LLC,  pursuant  to  which  we  agreed  to  the  accelerated
commissioning service, or the ACS, on the Gray Oak pipeline in the amount of 50,000 barrels of crude oil per day. Under the ACS program, shippers must
make a deficiency payment for any barrels not shipped during the ACS term, which expires the day before the Gray Oak pipeline goes into full service, which
is currently anticipated to occur in the second quarter of 2020. ACS commenced in November 2019 and is ongoing. Due to restrictive API gravity provisions
and the lack of markets, we have been unable to ship any volumes over the Gray Oak pipeline since the inception of the ACS.

Once full service commences on the Gray Oak pipeline, subject to the terms and conditions of this transportation services agreement, we will be
required to ship 50,000 barrels per day of crude oil on the Gray Oak pipeline or pay a deficiency payment for any shortfall in volumes as measured on a
quarterly basis. Such deficiency payments can be used as a credit against future shipments in excess of our minimum contract volume each quarter, subject to
certain restrictions.

Oil and Natural Gas Leases

The typical oil and natural gas lease agreement covering our properties provides for the payment of royalties to the mineral owner for all oil and
natural gas produced from any wells drilled on the leased premises. The lessor royalties and other leasehold burdens on our properties generally range from
12.50% to 30.00%, resulting in a net revenue interest to us generally ranging from 70.00% to 87.50%.

Seasonal Nature of Business

Generally,  demand  for  oil  increases  during  the  summer  months  and  decreases  during  the  winter  months  while  natural  gas  decreases  during  the
summer months and increases during the winter months. Certain natural gas users utilize natural gas storage facilities and purchase some of their anticipated
winter  requirements  during  the  summer,  which  can  lessen  seasonal  demand  fluctuations.  In  our  exploration  and  production  business,  seasonal  weather
conditions and lease stipulations can limit our drilling and producing activities and other oil and natural gas operations in a portion of our operating areas.
These seasonal anomalies can pose challenges for meeting our well drilling objectives and can increase competition for equipment, supplies and personnel
during  the  spring  and  summer  months,  which  could  lead  to  shortages  and  increase  costs  or  delay  operations.  In  our  midstream  operations  business,  the
volumes of condensate produced at Rattler’s processing facilities fluctuate seasonally, with volumes generally increasing in the winter months and decreasing
in the summer months as a result of the physical properties of natural gas and comingled liquids. Severe or prolonged summers may adversely affect our
results of operations in the midstream operations segment.

Regulation

Oil  and  natural  gas  operations  such  as  ours  are  subject  to  various  types  of  legislation,  regulation  and  other  legal  requirements  enacted  by
governmental  authorities.  This  legislation  and  regulation  affecting  the  oil  and  natural  gas  industry  is  under  constant  review  for  amendment  or  expansion.
Some of these requirements carry substantial penalties for failure to comply. The regulatory burden on the oil and natural gas industry increases our cost of
doing business and, consequently, affects our profitability.

Environmental Matters and Regulation

Our oil and natural gas exploration, development and production operations are subject to stringent laws and regulations governing the discharge of
materials into the environment or otherwise relating to environmental protection. Numerous federal, state and local governmental agencies, such as the EPA,
issue regulations that often require difficult and costly compliance measures that carry substantial administrative, civil and criminal penalties and may result
in injunctive obligations for non-

17

 
 
 
Table of Contents

compliance. These laws and regulations may require the acquisition of a permit before drilling commences, restrict the types, quantities and concentrations of
various substances that can be released into the environment in connection with drilling and production activities, limit or prohibit construction or drilling
activities on certain lands lying within wilderness, wetlands, ecologically or seismically sensitive areas, and other protected areas, require action to prevent or
remediate pollution from current or former operations, such as plugging abandoned wells or closing pits, result in the suspension or revocation of necessary
permits, licenses and authorizations, require that additional pollution controls be installed and impose substantial liabilities for pollution resulting from our
operations or related to our owned or operated facilities. Liability under such laws and regulations is often strict (i.e., no showing of “fault” is required) and
can be joint and several. 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 laws
and regulations occur frequently, and any changes that result in more stringent and costly pollution control or waste handling, storage, transport, disposal or
cleanup requirements could materially and adversely affect our operations and financial position, as well as the oil and natural gas industry in general. Our
management believes that we are in substantial compliance with applicable environmental laws and regulations and we have not experienced any material
adverse effect from compliance with these environmental requirements. This trend, however, may not continue in the future.

Waste Handling. The Resource Conservation and Recovery Act, as amended, and comparable state statutes and regulations promulgated thereunder,
affect oil and natural gas exploration, development and production 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
the Resource Conservation and Recovery Act, sometimes in conjunction with their own, more stringent requirements. Although most wastes associated with
the exploration, development and production of crude oil and natural gas are exempt from regulation as hazardous wastes under the Resource Conservation
and Recovery Act, such wastes may constitute “solid wastes” that are subject to the less stringent non-hazardous waste requirements. Moreover, the EPA or
state  or  local  governments  may  adopt  more  stringent  requirements  for  the  handling  of  non-hazardous  wastes  or  categorize  some  non-hazardous  wastes  as
hazardous for future regulation. Indeed, legislation has been proposed from time to time in Congress to re-categorize certain oil and natural gas exploration,
development and production wastes as “hazardous wastes.” Also, in December 2016, the EPA agreed in a consent decree to review its regulation of oil and
gas waste. However, in April 2019, the EPA concluded that revisions to the federal regulations for the management of oil and gas waste are not necessary at
this time. Any such changes in the laws and regulations could have a material adverse effect on our capital expenditures and operating expenses.

Administrative,  civil  and  criminal  penalties  can  be  imposed  for  failure  to  comply  with  waste  handling  requirements.  We  believe  that  we  are  in
substantial compliance with applicable requirements related to waste handling, and that we hold all necessary and up-to-date permits, registrations and other
authorizations to the extent that our operations require them under such laws and regulations. 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,  as  amended,  which  we
refer to as CERCLA or the “Superfund” law, 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. Under CERCLA and comparable state statutes, persons deemed “responsible parties” are
subject to strict liability that, in some circumstances, may be joint and several for the costs of removing or remediating previously disposed wastes (including
wastes  disposed  of  or  released  by  prior  owners  or  operators)  or  property  contamination  (including  groundwater  contamination),  for  damages  to  natural
resources  and  for  the  costs  of  certain  health  studies.  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 statutes. 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.

Water Discharges. The Federal Water Pollution Control Act of 1972, as amended, also known as the “Clean Water Act,” the Safe Drinking Water
Act, the Oil Pollution Act and analogous state laws and regulations promulgated thereunder impose restrictions and strict controls regarding the unauthorized
discharge  of  pollutants,  including  produced  waters  and  other  gas  and  oil  wastes,  into  navigable  waters  of  the  United  States,  as  well  as  state  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. Spill prevention,
control  and  countermeasure  plan  requirements  under  federal  law  require  appropriate  containment  berms  and  similar  structures  to  help  prevent  the
contamination of navigable waters in the event of a petroleum hydrocarbon tank spill, rupture or leak. The Clean

18

Table of Contents

Water  Act  and  regulations  implemented  thereunder  also  prohibit  the  discharge  of  dredge  and  fill  material  into  regulated  waters,  including  jurisdictional
wetlands,  unless  authorized  by  an  appropriately  issued  permit.  On  June  29,  2015,  the  EPA  and  the  U.S.  Army  Corps  of  Engineers,  or  the  Corps,  jointly
promulgated final rules redefining the scope of waters protected under the Clean Water Act. However, on October 22, 2019, the agencies published a final
rule to repeal the 2015 rules. The 2015 rule and the 2019 repeal are subject to several ongoing legal challenges. Also, on January 23, 2020, the EPA and the
Corps released a final rule replacing the 2015 rule, and significantly reducing the waters subject to federal regulation under the Clean Water Act. The rule is
anticipated to generate further legal challenges. Further, on April 23, 2019, the EPA published an interpretive statement and request for comment, clarifying
that the Clean Water Act’s permitting program for pollutant discharges does not apply to releases of pollutants to groundwater. As a result of such recent
developments, substantial uncertainty exists regarding the scope of waters protected under the Clean Water Act. To the extent the rules expand the range of
properties  subject  to  the  Clean  Water  Act’s  jurisdiction,  we  could  face  increased  costs  and  delays  with  respect  to  obtaining  permits  for  dredge  and  fill
activities in wetland areas.

The  EPA  has  also  adopted  regulations  requiring  certain  oil  and  natural  gas  exploration  and  production  facilities  to  obtain  individual  permits  or
coverage  under  general  permits  for  storm  water  discharges.  In  addition,  on  June  28,  2016,  the  EPA  published  a  final  rule  prohibiting  the  discharge  of
wastewater from onshore unconventional oil and gas extraction facilities to publicly owned wastewater treatment plants, which regulations are discussed in
more detail below under the caption “–Regulation of Hydraulic Fracturing.” Costs may be associated with the treatment of wastewater or developing and
implementing storm water pollution prevention plans, as well as for monitoring and sampling the storm water runoff from certain of our facilities. Some states
also maintain groundwater protection programs that require permits for discharges or operations that may impact groundwater conditions.

The  Oil  Pollution  Act  is  the  primary  federal  law  for  oil  spill  liability.  The  Oil  Pollution  Act  contains  numerous  requirements  relating  to  the
prevention of and response to petroleum releases into waters of the United States, including the requirement that operators of offshore facilities and certain
onshore  facilities  near  or  crossing  waterways  must  develop  and  maintain  facility  response  contingency  plans  and  maintain  certain  significant  levels  of
financial assurance to cover potential environmental cleanup and restoration costs. The Oil Pollution Act subjects owners of facilities to strict liability that, in
some  circumstances,  may  be  joint  and  several  for  all  containment  and  cleanup  costs  and  certain  other  damages  arising  from  a  release,  including,  but  not
limited to, the costs of responding to a release of oil to surface waters.

Non-compliance with the Clean Water Act or the Oil Pollution Act may result in substantial administrative, civil and criminal penalties, as well as

injunctive obligations. We believe we are in material compliance with the requirements of each of these laws.

Air Emissions. The  federal  Clean  Air  Act,  as  amended,  and  comparable  state  laws  and  regulations,  regulate  emissions  of  various  air  pollutants
through the issuance of permits and the imposition of other requirements. The EPA has developed, and continues to develop, stringent regulations governing
emissions  of  air  pollutants  at  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. For example, on August 16, 2012, the EPA published final
regulations  under  the  federal  Clean  Air  Act  that  establish  new  emission  controls  for  oil  and  natural  gas  production  and  processing  operations,  which
regulations are discussed in more detail below in “–Regulation of Hydraulic Fracturing.” Also, on May 12, 2016, the EPA issued a final rule regarding the
criteria for aggregating multiple small surface sites into a single source for air-quality permitting purposes applicable to the oil and gas industry. This rule
could cause small facilities, on an aggregate basis, to be deemed a major source, thereby triggering more stringent air permitting processes and requirements.
These laws and regulations may increase the costs of compliance for some facilities we own or operate, and federal and state regulatory agencies can impose
administrative, civil and criminal penalties for non-compliance with air permits or other requirements of the federal Clean Air Act and associated state laws
and regulations.  We  believe  that  we  are  in  substantial  compliance  with  all  applicable  air  emissions  regulations  and  that  we  hold  all  necessary  and  valid
construction  and  operating  permits  for  our  operations.  Obtaining  or  renewing  permits  has  the  potential  to  delay  the  development  of  oil  and  natural  gas
projects.

Climate  Change.  In  recent  years,  federal,  state  and  local  governments  have  taken  steps  to  reduce  emissions  of  greenhouse  gases.  The  EPA  has
finalized a series of greenhouse gas monitoring, reporting and emissions control rules for the oil and natural gas industry, and the U.S. Congress has, from
time  to  time,  considered  adopting  legislation  to  reduce  emissions.  Almost  one-half  of  the  states  have  already  taken  measures  to  reduce  emissions  of
greenhouse gases primarily through the development of greenhouse gas emission inventories and/or regional greenhouse gas cap-and-trade programs.

At the international level, in December 2015, the United States participated in 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  Agreement  went  into  effect  on  November  4,  2016.  The
Agreement establishes a framework for the parties

19

Table of Contents

to  cooperate  and  report  actions  to  reduce  greenhouse  gas  emissions.  However,  on  June  1,  2017,  President  Trump  announced  that  the  United  States  would
withdraw from the Paris Agreement, and begin negotiations to either re-enter or negotiate an entirely new agreement with more favorable terms for the United
States. The Paris Agreement sets forth a specific exit process, whereby a party may not provide notice of its withdrawal until three years from the effective
date, with such withdrawal taking effect one year from such notice. On November 4, 2019, the Trump Administration submitted its formal notification of
withdrawal to the United Nations. It is not clear what steps, if any, will be taken to negotiate a new agreement, or what terms would be included in such an
agreement. In response to the announcement, many state and local leaders have stated their intent to intensify efforts to uphold the commitments set forth in
the international accord.

Restrictions  on  emissions  of  methane  or  carbon  dioxide  that  may  be  imposed  could  adversely  impact  the  demand  for,  price  of,  and  value  of  our
products and reserves. As our operations also emit greenhouse gases directly, current and future laws or regulations limiting such emissions could increase
our  own  costs.  At  this  time,  it  is  not  possible  to  accurately  estimate  how  potential  future  laws  or  regulations  addressing  greenhouse  gas  emissions  would
impact our business.

In addition, there have also been efforts in recent years to influence the investment community, including investment advisors and certain sovereign
wealth,  pension  and  endowment  funds  promoting  divestment  of  fossil  fuel  equities  and  pressuring  lenders  to  limit  funding  to  companies  engaged  in  the
extraction of fossil fuel reserves. Such environmental activism and initiatives aimed at limiting climate change and reducing air pollution could interfere with
our  business  activities,  operations  and  ability  to  access  capital.  Furthermore,  claims  have  been  made  against  certain  energy  companies  alleging  that
greenhouse  gas  emissions  from  oil  and  natural  gas  operations  constitute  a  public  nuisance  under  federal  and/or  state  common  law.  As  a  result,  private
individuals or public entities may seek to enforce environmental laws and regulations against us and could allege personal injury, property damages or other
liabilities. While our business is not a party to any such litigation, we could be named in actions making similar allegations. An unfavorable ruling in any
such case could significantly impact our operations and could have an adverse impact on our financial condition.

Moreover, there has been public discussion that climate change may be associated with extreme weather conditions such as more intense hurricanes,
thunderstorms,  tornadoes  and  snow  or  ice  storms,  as  well  as  rising  sea  levels.  Another  possible  consequence  of  climate  change  is  increased  volatility  in
seasonal temperatures. Some studies indicate that climate change could cause some areas to experience temperatures substantially hotter or colder than their
historical averages. Extreme weather conditions can interfere with our production and increase our costs and damage resulting from extreme weather may not
be  fully  insured.  However,  at  this  time,  we  are  unable  to  determine  the  extent  to  which  climate  change  may  lead  to  increased  storm  or  weather  hazards
affecting our operations.

Regulation of Hydraulic Fracturing

Hydraulic fracturing is an important common practice that is used to stimulate production of hydrocarbons 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, legislation has been proposed in recent sessions of Congress to amend
the Safe Drinking Water Act to repeal the exemption for hydraulic fracturing from the definition of “underground injection,” to require federal permitting and
regulatory  control  of  hydraulic  fracturing,  and  to  require  disclosure  of  the  chemical  constituents  of  the  fluids  used  in  the  fracturing  process.  Furthermore,
several federal agencies have asserted regulatory authority over certain aspects of the process. For example, the EPA has taken the position that hydraulic
fracturing with fluids containing diesel fuel is subject to regulation under the Underground Injection Control program, specifically as “Class II” Underground
Injection Control wells under the Safe Drinking Water Act.

On June 28, 2016, the EPA published a final rule prohibiting the discharge of wastewater from onshore unconventional oil and natural gas extraction
facilities  to  publicly  owned  wastewater  treatment  plants.  The  EPA  is  also  conducting  a  study  of  private  wastewater  treatment  facilities  (also  known  as
centralized waste treatment, or CWT, facilities) accepting oil and natural gas extraction wastewater. The EPA is collecting data and information related to the
extent  to  which  CWT  facilities  accept  such  wastewater,  available  treatment  technologies  (and  their  associated  costs),  discharge  characteristics,  financial
characteristics of CWT facilities, and the environmental impacts of discharges from CWT facilities.

On August 16, 2012, the EPA published final regulations under the federal Clean Air Act that establish new air emission controls for oil and natural
gas production and natural gas processing operations. Specifically, the EPA’s rule package includes New Source Performance standards to address emissions
of sulfur dioxide and volatile organic compounds and a separate set of emission standards to address hazardous air pollutants frequently associated with oil
and natural gas production and processing activities. The final rules seek to achieve a 95% reduction in volatile organic compounds emitted by requiring the
use of reduced emission completions or “green completions” on all hydraulically-fractured wells constructed or refractured after January 1, 2015. The rules
also establish specific new requirements regarding emissions from compressors, controllers, dehydrators, storage

20

Table of Contents

tanks  and  other  production  equipment.  The  EPA  received  numerous  requests  for  reconsideration  of  these  rules  from  both  industry  and  the  environmental
community, and court challenges to the rules were also filed. In response, the EPA has issued, and will likely continue to issue, revised rules responsive to
some of the requests for reconsideration. In particular, on May 12, 2016, the EPA amended its regulations to impose new standards for methane and volatile
organic compounds emissions for certain new, modified, and reconstructed equipment, processes, and activities across the oil and natural gas sector. However,
in a March 28, 2017 executive order, President Trump directed the EPA to review the 2016 regulations and, if appropriate, to initiate a rulemaking to rescind
or revise them consistent with the stated policy of promoting clean and safe development of the nation’s energy resources, while at the same time avoiding
regulatory  burdens  that  unnecessarily  encumber  energy  production.  On  June  16,  2017,  the  EPA  published  a  proposed  rule  to  stay  for  two  years  certain
requirements of the 2016 regulations, including fugitive emission requirements. Also, on October 15, 2018, the EPA published a proposed rule to significantly
reduce regulatory burdens imposed by the 2016 regulations, including, for example, reducing the monitoring frequency for fugitive emissions and revising the
requirements  for  pneumatic  pumps  at  well  sites.  In  addition,  on  August  28,  2019,  the  EPA  proposed  amendments  to  the  2012  and  2016  New  Source
Performance  standards  to  ease  regulatory  burdens,  including  rescinding  standards  applicable  to  transmission  or  storage  segments  and  eliminating  methane
requirements  altogether.  Legal  challenges  are  anticipated  and  thus  substantial  uncertainty  exists  regarding  the  scope  of  these  New  Source  Performance
standards for oil and natural gas operations. The 2012 and 2016 New Source Performance standards, to the extent implemented, as well as any future laws
and their implementing regulations, may require us to obtain pre-approval for the expansion or modification of existing facilities or the construction of new
facilities expected to produce air emissions, impose stringent air permit requirements, or mandate the use of specific equipment or technologies to control
emissions.

Furthermore, there are certain governmental reviews either underway or being proposed that focus on environmental aspects of hydraulic fracturing
practices. On December 13, 2016, the EPA released a study examining the potential for hydraulic fracturing activities to impact drinking water resources,
finding that, under some circumstances, the use of water in hydraulic fracturing activities can impact drinking water resources. Also, on February 6, 2015, the
EPA  released  a  report  with  findings  and  recommendations  related  to  public  concern  about  induced  seismic  activity  from  disposal  wells.  The  report
recommends strategies for managing and minimizing the potential for significant injection-induced seismic events. Other governmental agencies, including
the U.S. Department of Energy, the U.S. Geological Survey, and the U.S. Government Accountability Office, have evaluated or are evaluating various other
aspects of hydraulic fracturing. These ongoing or proposed studies could spur initiatives to further regulate hydraulic fracturing, and could ultimately make it
more difficult or costly for us to perform fracturing and increase our costs of compliance and doing business.

Several states, including Texas, and local jurisdictions, 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.
The  Texas  Legislature  adopted  legislation,  effective  September  1,  2011,  requiring  oil  and  gas  operators  to  publicly  disclose  the  chemicals  used  in  the
hydraulic fracturing process. The Texas Railroad Commission adopted rules and regulations implementing this legislation that apply to all wells for which the
Texas  Railroad  Commission  issues  an  initial  drilling  permit  after  February  1,  2012.  The  law  requires  that  the  well  operator  disclose  the  list  of  chemical
ingredients subject to the requirements of OSHA for disclosure on an internet website and also file the list of chemicals with the Texas Railroad Commission
with the well completion report. The total volume of water used to hydraulically fracture a well must also be disclosed to the public and filed with the Texas
Railroad Commission. Also, in May 2013, the Texas Railroad Commission adopted rules governing well casing, cementing and other standards for ensuring
that hydraulic fracturing operations do not contaminate nearby water resources. The rules took effect in January 2014. Additionally, on October 28, 2014, the
Texas  Railroad  Commission  adopted  disposal  well  rule  amendments  designed,  among  other  things,  to  require  applicants  for  new  disposal  wells  that  will
receive non-hazardous produced water and hydraulic fracturing flowback fluid to conduct seismic activity searches utilizing the U.S. Geological Survey. The
searches are intended to determine the potential for earthquakes within a circular area of 100 square miles around a proposed new disposal well. The disposal
well  rule  amendments,  which  became  effective  on  November  17,  2014,  also  clarify  the  Texas  Railroad  Commission’s  authority  to  modify,  suspend  or
terminate a disposal well permit if scientific data indicates a disposal well is likely to contribute to seismic activity. The Texas Railroad Commission has used
this authority to deny permits for waste disposal wells.

There  has  been  increasing  public  controversy  regarding  hydraulic  fracturing  with  regard  to  the  use  of  fracturing  fluids,  induced  seismic  activity,
impacts on drinking water supplies, use of water and the potential for impacts to surface water, groundwater and the environment generally. A number of
lawsuits and enforcement actions have been initiated across the country implicating hydraulic fracturing practices. If new laws or regulations that significantly
restrict  hydraulic  fracturing  are  adopted,  such  laws  could  make  it  more  difficult  or  costly  for  us  to  perform  fracturing  to  stimulate  production  from  tight
formations as well as make it easier for third parties opposing the hydraulic fracturing process to initiate legal proceedings based on allegations that specific
chemicals used in the fracturing process could adversely affect groundwater. In addition, if hydraulic fracturing is further regulated at the federal,  state  or
local  level,  our  fracturing  activities  could  become  subject  to  additional  permitting  and  financial  assurance  requirements,  more  stringent  construction
specifications,  increased  monitoring,  reporting  and  recordkeeping  obligations,  plugging  and  abandonment  requirements  and  also  to  attendant  permitting
delays and potential increases in costs.

Such changes could cause us to incur substantial compliance costs, and compliance or the consequences of any failure to comply by us could have a material
adverse effect on our financial condition and results of operations. At this time, it is not possible to estimate the impact on our business of newly enacted or
potential federal, state or local laws governing hydraulic fracturing.

Endangered Species

The federal Endangered Species Act, or ESA, and analogous state laws restrict activities that may affect listed endangered or threatened species or
their  habitats.  If  endangered  species  are  located  in  areas  where  we  operate,  our  operations  or  any  work  performed  related  to  them  could  be  prohibited  or
delayed or expensive mitigation may be required. While some of our operations may be located in areas that are designated as habitats for endangered or
threatened species, we believe that we are in compliance with the ESA. On August 12, 2019, the U.S. Fish and Wildlife Service and the National Oceanic and
Atmospheric Administration’s National Marine Fisheries Service jointly published final rules that, among other things, tighten the critical habitat designation
process and eliminate certain automatic protections for threatened species going forward. Nevertheless, the designation of previously unprotected species in
areas where we operate as threatened or endangered could result in the imposition of restrictions on our operations and consequently have a material adverse
effect on our business.

Other Regulation of the Oil and Natural Gas Industry

The oil and natural gas industry is extensively regulated by numerous federal, state and local authorities. Legislation affecting the oil and natural gas
industry is under constant review for amendment or expansion, frequently increasing the regulatory burden. Also, numerous departments and agencies, both
federal and state, are authorized by statute to issue rules and regulations that are binding on the oil and natural gas industry and its individual members, some
of  which  carry  substantial  penalties  for  failure  to  comply.  Although  the  regulatory  burden  on  the  oil  and  natural  gas  industry  increases  our  cost  of  doing
business and, consequently, affects our profitability, these burdens generally do not affect us any differently or to any greater or lesser extent than they affect
other companies in the industry with similar types, quantities and locations of production.

The availability, terms and cost of transportation significantly affect sales of oil and natural gas. The interstate transportation and sale for resale of oil
and natural gas is subject to federal regulation, including regulation of the terms, conditions and rates for interstate transportation, storage and various other
matters,  primarily  by  FERC.  Federal  and  state  regulations  govern  the  price  and  terms  for  access  to  oil  and  natural  gas  pipeline  transportation.  FERC’s
regulations for interstate oil and natural gas transmission in some circumstances may also affect the intrastate transportation of oil and natural gas.

Although oil and natural gas prices are currently unregulated, Congress historically has been active in the area of oil and natural gas regulation. We
cannot predict whether new legislation to regulate oil and natural gas might be proposed, what proposals, if any, might actually be enacted by Congress or the
various  state  legislatures,  and  what  effect,  if  any,  the  proposals  might  have  on  our  operations.  Sales  of  condensate  and  oil  and  natural  gas  liquids  are  not
currently regulated and are made at market prices.

Drilling and Production.  Our  operations  are  subject  to  various  types  of  regulation  at  the  federal,  state  and  local  level.  These  types  of  regulation
include requiring permits for the drilling of wells, drilling bonds and reports concerning operations. The state, and some counties and municipalities, in which
we operate also regulate one or more of the following:

•

•

•

•

•

•

•

the location of wells;

the method of drilling and casing wells;

the timing of construction or drilling activities, including seasonal wildlife closures;

the rates of production or “allowables”;

the surface use and restoration of properties upon which wells are drilled;

the plugging and abandoning of wells; and

notice to, and consultation with, surface owners and other third parties.

State laws regulate the size and shape of drilling and spacing units or proration units governing the pooling of oil and natural gas properties. Some
states allow forced pooling or integration of tracts to facilitate exploration while other states rely on voluntary pooling of lands and leases. In some instances,
forced pooling or unitization may be implemented by third parties

22

Table of Contents

and may reduce our interest in the unitized properties. In addition, state conservation laws establish maximum rates of production from oil and natural gas
wells, generally prohibit the venting or flaring of natural gas and impose requirements regarding the ratability of production. These laws and regulations may
limit the amount of oil and natural gas we can produce from our wells or limit the number of wells or the locations at which we can drill. Moreover, each state
generally imposes a production or severance tax with respect to the production and sale of oil, natural gas and natural gas liquids within its jurisdiction. States
do not regulate wellhead prices or engage in other similar direct regulation, but we cannot assure you that they will not do so in the future. The effect of such
future regulations may be to limit the amounts of oil and natural gas that may be produced from our wells, negatively affect the economics of production from
these wells or to limit the number of locations we can drill.

Federal,  state  and  local  regulations  provide  detailed  requirements  for  the  plugging  and  abandonment  of  wells,  closure  or  decommissioning  of
production facilities and pipelines and for site restoration in areas where we operate. Although the Corps does not require bonds or other financial assurances,
some state agencies and municipalities do have such requirements.

Natural Gas Sales and Transportation. Historically, federal legislation and regulatory controls have affected the price of the natural gas we produce
and the manner in which we market our production. FERC has jurisdiction over the transportation and sale for resale of natural gas in interstate commerce by
natural gas companies under the Natural Gas Act of 1938 and the Natural Gas Policy Act of 1978. Since 1978, various federal laws have been enacted which
have resulted in the complete removal of all price and non-price controls for sales of domestic natural gas sold in “first sales,” which include all of our sales
of our own production. Under the Energy Policy Act of 2005, FERC has substantial enforcement authority to prohibit the manipulation of natural gas markets
and enforce its rules and orders, including the ability to assess substantial civil penalties.

FERC also regulates interstate natural gas transportation rates and service conditions and establishes the terms under which we may use interstate
natural gas pipeline capacity, which affects the marketing of natural gas that we produce, as well as the revenues we receive for sales of our natural gas and
release  of  our  natural  gas  pipeline  capacity.  Commencing  in  1985,  FERC  promulgated  a  series  of  orders,  regulations  and  rule  makings  that  significantly
fostered  competition  in  the  business  of  transporting  and  marketing  gas.  Today,  interstate  pipeline  companies  are  required  to  provide  nondiscriminatory
transportation  services  to  producers,  marketers  and  other  shippers,  regardless  of  whether  such  shippers  are  affiliated  with  an  interstate  pipeline  company.
FERC’s initiatives have led to the development of a competitive, open access market for natural gas purchases and sales that permits all purchasers of natural
gas to buy gas directly from third-party sellers other than pipelines. However, the natural gas industry historically has been very heavily regulated; therefore,
we cannot guarantee that the less stringent regulatory approach currently pursued by FERC and Congress will continue indefinitely into the future nor can we
determine what effect, if any, future regulatory changes might have on our natural gas related activities.

Under  FERC’s  current  regulatory  regime,  transmission  services  are  provided  on  an  open-access,  non-discriminatory  basis  at  cost-based  rates  or
negotiated  rates.  Gathering  service,  which  occurs  upstream  of  jurisdictional  transmission  services,  is  regulated  by  the  states  onshore  and  in  state  waters.
Although  its  policy  is  still  in  flux,  FERC  has  in  the  past  reclassified  certain  jurisdictional  transmission  facilities  as  non-jurisdictional  gathering  facilities,
which has the tendency to increase our costs of transporting gas to point-of-sale locations.

Natural Gas Gathering. Although FERC has not made a formal determination with respect to the facilities Rattler LLC considers to be natural gas
gathering pipelines, Rattler believes that its natural gas gathering pipelines meet the traditional tests that FERC has used to determine that pipelines perform
primarily a gathering function and are, therefore, not subject to FERC jurisdiction. The distinction between FERC-regulated interstate transportation services
and federally unregulated gathering services, however, has been the subject of substantial litigation, and FERC determines whether facilities are gathering
facilities on a case-by-case basis, so the classification and regulation of gathering facilities is subject to change based on future determinations by FERC, the
courts or Congress. If FERC were to consider the status of an individual facility and determine that the facility or services provided by it are not exempt from
FERC  regulation  under  the  Natural  Gas  Act  of  1938,  or  NGA,  and  that  the  facility  provides  interstate  transportation  service,  the  rates  for,  and  terms  and
conditions  of,  services  provided  by  such  facility  would  be  subject  to  regulation  by  FERC  under  the  NGA  or  the  Natural  Gas  Policy  Act,  or  NGPA.  Such
regulation could decrease revenue, increase operating costs and, depending upon the facility in question, adversely affect results of operations and cash flow.
In addition, if any of the facilities were found to have provided services or otherwise operated in violation of the NGA or NGPA, this could result in the
imposition of substantial civil penalties, as well as a requirement to disgorge revenues collected for such services in excess of the maximum rates established
by FERC.

Even though Rattler LLC considers its natural gas gathering pipelines to be exempt from the jurisdiction of FERC under the NGA, FERC regulation
of interstate natural gas transportation pipelines may indirectly impact gathering services. FERC’s policies and practices across the range of its natural gas
regulatory activities, including, for example, its policies on interstate open access transportation, ratemaking, capacity release and market center promotion
may  indirectly  affect  intrastate  markets  and  gathering  services.  In  recent  years,  FERC  has  pursued  pro-competitive  policies  in  its  regulation  of  interstate
natural

23

Table of Contents

gas pipelines. However, there can be no assurance that the FERC will continue to pursue this approach as it considers matters such as pipeline rates and rules
and policies that may indirectly affect the natural gas gathering services.

Natural gas gathering may receive greater regulatory scrutiny at the state level; therefore, Rattler LLC’s natural gas gathering operations could be
adversely affected should they become subject to the application of state regulation of rates and services. Gathering operations could also be subject to safety
and  operational  regulations  relating  to  the  design,  construction,  testing,  operation,  replacement  and  maintenance  of  gathering  facilities.  We  cannot  predict
what  effect,  if  any,  such  changes  might  have  on  Rattler’s  or  our  operations,  but  additional  capital  expenditures  and  increased  operating  costs  may  result
depending on future legislative and regulatory changes.

Oil Sales and Transportation. Sales of crude oil, condensate and natural gas liquids are not currently regulated and are made at negotiated prices.

Nevertheless, Congress could reenact price controls in the future.

Our crude oil sales are affected by the availability, terms and cost of transportation. The transportation of oil in common carrier pipelines is also
subject to rate regulation. FERC regulates interstate oil pipeline transportation rates under the Interstate Commerce Act, and our subsidiary Rattler Midstream
Operating LLC has a tariff on file with FERC to perform gathering service in interstate commerce. Intrastate oil pipeline transportation rates are subject to
regulation  by  state  regulatory  commissions.  The  basis  for  intrastate  oil  pipeline  regulation,  and  the  degree  of  regulatory  oversight  and  scrutiny  given  to
intrastate oil pipeline rates, varies from state to state. Insofar as effective interstate and intrastate rates are equally applicable to all comparable shippers, we
believe  that  the  regulation  of  oil  transportation  rates  will  not  affect  our  operations  in  any  materially  different  way  than  such  regulation  will  affect  the
operations of our competitors.

Further, interstate and intrastate common carrier oil pipelines, including our subsidiary Rattler Midstream Operating LLC, must provide service on a
non-discriminatory basis. Under this open access standard, common carriers must offer service to all shippers requesting service on the same terms and under
the  same  rates.  When  oil  pipelines  operate  at  full  capacity,  access  is  governed  by  prorationing  provisions  set  forth  in  the  pipelines’  published  tariffs.
Accordingly, we believe that access to oil pipeline transportation services generally will be available to us to the same extent as to our competitors.

Safety and Maintenance Regulation. In our midstream operations, Rattler LLC is subject to regulation by the U.S. Department of Transportation, or
DOT,  under  the  Hazardous  Liquids  Pipeline  Safety  Act  of  1979,  or  HLPSA,  and  comparable  state  statutes  with  respect  to  design,  installation,  testing,
construction,  operation,  replacement  and  management  of  pipeline  facilities.  HLPSA  covers  petroleum  and  petroleum  products,  including  NGLs  and
condensate, and requires any entity that owns or operates pipeline facilities to comply with such regulations, to permit access to and copying of records and to
file  certain  reports  and  provide  information  as  required  by  the  United  States  Secretary  of  Transportation.  These  regulations  include  potential  fines  and
penalties for violations. We believe that we are in compliance in all material respects with these HLPSA regulations.

Rattler  LLC  is  also  subject  to  the  Natural  Gas  Pipeline  Safety  Act  of  1968,  or  NGPSA,  and  the  Pipeline  Safety  Improvement  Act  of  2002.  The
NGPSA  regulates  safety  requirements  in  the  design,  construction,  operation  and  maintenance  of  natural  gas  pipeline  facilities  while  the  Pipeline  Safety
Improvement Act establishes mandatory inspections for all United States crude oil and natural gas transportation pipelines and some gathering pipelines in
high-consequence areas within ten years. DOT, through the Pipeline and Hazardous Materials Safety Administration, or PHMSA, has developed regulations
implementing the Pipeline Safety Improvement Act that requires pipeline operators to implement integrity management programs, including more frequent
inspections and other safety protections in areas where the consequences of potential pipeline accidents pose the greatest risk to people and their property.

The Pipeline Safety and Job Creation Act, enacted in 2011, and the Protecting our Infrastructure of Pipelines and Enhancing Safety Act of 2016, also
known  as  the  PIPES  Act,  enacted  in  2016,  amended  the  HLPSA  and  NGPSA  and  increased  safety  regulation.  The  Pipeline  Safety  and  Job  Creation  Act
doubles the maximum administrative fines for safety violations from $100,000 to $200,000 for a single violation and from $1.0 million to $2.0 million for a
related  series  of  violations  (now  increased  for  inflation  to  $218,647  and  $2,186,465,  respectively),  and  provides  that  these  maximum  penalty  caps  do  not
apply to civil enforcement actions, establishes additional safety requirements for newly constructed pipelines, and requires studies of certain safety issues that
could result in the adoption of new regulatory requirements for existing pipelines, including the expansion of integrity management, use of automatic and
remote-controlled shut-off valves, leak detection systems, sufficiency of existing regulation of gathering pipelines, use of excess flow valves, verification of
maximum  allowable  operating  pressure,  incident  notification,  and  other  pipeline-safety  related  requirements.  The  PIPES  Act  ensures  that  the  PHMSA
completes the Pipeline Safety and Job Creation Act requirements; reforms PHMSA to be a more dynamic, data-driven regulator; and closes gaps in federal
standards.

PHMSA has undertaken rulemakings to address many areas of this legislation. For example, on October 1, 2019, PHMSA published final rules to

expand its integrity management requirements and impose new pressure testing requirements

24

Table of Contents

on regulated pipelines, including certain segments outside High Consequence Areas. The rules, once effective, also extend reporting requirements to certain
previously unregulated gathering lines. The safety enhancement requirements and other provisions of the Pipeline Safety and Job Creation Act and the PIPES
Act, as well as any implementation of PHMSA rules thereunder and/or related rule making proceedings, could require us to install new or modified safety
controls, pursue additional capital projects or conduct maintenance programs on an accelerated basis, any or all of which tasks could result in our incurring
increased operating costs that could have a material adverse effect on our results of operations or financial position. In addition, any material penalties or fines
issued to us under these or other statutes, rules, regulations or orders could have an adverse impact on our business, financial condition, results of operation
and cash flow.

States  are  largely  preempted  by  federal  law  from  regulating  pipeline  safety  but  may  assume  responsibility  for  enforcing  intrastate  pipeline
regulations  at  least  as  stringent  as  the  federal  standards,  and  many  states  have  undertaken  responsibility  to  enforce  the  federal  standards.  The  Railroad
Commission of Texas is the agency vested with intrastate natural gas pipeline regulatory and enforcement authority in Texas. The Commission’s regulations
adopt by reference the minimum federal safety standards for the transportation of natural gas. In addition, on December 17, 2019, the Commission adopted
rules requiring that operators of gathering lines take 'appropriate' actions to fix safety hazards. We do not anticipate any significant problems in complying
with applicable federal and state laws and regulations in Texas. Our gathering pipelines have ongoing inspection and compliance programs designed to keep
the facilities in compliance with pipeline safety and pollution control requirements.

In addition, we are subject to the requirements of the federal Occupational Safety and Health Act, or OSHA, and comparable state statutes, whose
purpose is to protect the health and safety of workers. Moreover, the OSHA hazard communication standard, the EPA community right-to-know regulations
under Title III of the federal Superfund Amendment and Reauthorization Act and comparable state statutes require that information be maintained concerning
hazardous  materials  used  or  produced  in  our  operations  and  that  this  information  be  provided  to  employees,  state  and  local  government  authorities  and
citizens. Rattler LLC and the entities in which it owns an interest are also subject to OSHA Process Safety Management regulations, which are designed to
prevent or minimize the consequences of catastrophic releases of toxic, reactive, flammable or explosive chemicals. These regulations apply to any process
which involves a chemical at or above specified thresholds, or any process which involves flammable liquid or gas, pressurized tanks, caverns and wells in
excess of 10,000 pounds at various locations. Flammable liquids stored in atmospheric tanks below their normal boiling point without the benefit of chilling
or  refrigeration  are  exempt  from  these  standards.  Also,  the  Department  of  Homeland  Security  and  other  agencies  such  as  the  EPA  continue  to  develop
regulations concerning the security of industrial facilities, including crude oil and natural gas facilities. We are subject to a number of requirements and must
prepare Federal Response Plans to comply. We must also prepare Risk Management Plans under the regulations promulgated by the EPA to implement the
requirements  under  the  CAA  to  prevent  the  accidental  release  of  extremely  hazardous  substances.  We  have  an  internal  program  of  inspection  designed  to
monitor and enforce compliance with safeguard and security requirements. We believe that we are in compliance in all material respects with all applicable
laws and regulations relating to safety and security.

State Regulation. Texas regulates the drilling for, and the production, gathering and sale of, oil and natural gas, including imposing severance taxes
and requirements for obtaining drilling permits. Texas currently imposes a 4.6% severance tax on oil production and a 7.5% severance tax on natural gas
production. States also regulate the method of developing new fields, the spacing and operation of wells and the prevention of waste of oil and natural gas
resources. States may regulate rates of production and may establish maximum daily production allowables from oil and natural gas wells based on market
demand or resource conservation, or both. States do not regulate wellhead prices or engage in other similar direct economic regulation, but we cannot assure
you that they will not do so in the future. The effect of these regulations may be to limit the amount of oil and natural gas that may be produced from our
wells and to limit the number of wells or locations we can drill.

The petroleum industry is also subject to compliance with various other federal, state and local regulations and laws. Some of those laws relate to

resource conservation and equal employment opportunity. We do not believe that compliance with these laws will have a material adverse effect on us.

Operational Hazards and Insurance

The oil and natural gas industry involves a variety of operating risks, including the risk of fire, explosions, blow outs, pipe failures and, in some
cases, abnormally high pressure formations which could lead to environmental hazards such as oil spills, natural gas leaks and the discharge of toxic gases. If
any  of  these  should  occur,  we  could  incur  legal  defense  costs  and  could  be  required  to  pay  amounts  due  to  injury,  loss  of  life,  damage  or  destruction  to
property, natural resources and equipment, pollution or environmental damage, regulatory investigation and penalties and suspension of operations.

In  accordance  with  what  we  believe  to  be  industry  practice,  we  maintain  insurance  against  some,  but  not  all,  of  the  operating  risks  to  which  our
business is exposed. We currently have insurance policies for onshore property (oil lease property/production equipment) for selected locations, rig physical
damage protection, control of well protection for selected wells,

25

Table of Contents

comprehensive  general  liability,  commercial  automobile,  workers  compensation,  pollution  liability  (claims  made  coverage  with  a  policy  retroactive  date),
excess umbrella liability and other coverage.

Our insurance is subject to exclusion and limitations, and there is no assurance that such coverage will fully or adequately protect us against liability
from all potential consequences, damages and losses. Any of these operational hazards could cause a significant disruption to our business. A loss not fully
covered by insurance could have a material adverse effect on our financial position, results of operations and cash flows. See Item 1A. “Risk Factors–Risks
Related to the Oil and Natural Gas Industry and Our Business–Operating hazards and uninsured risks may result in substantial losses and could prevent us
from realizing profits.”

We reevaluate the purchase of insurance, policy terms and limits annually. Future insurance coverage for our industry could increase in cost and may
include higher deductibles or retentions. In addition, some forms of insurance may become unavailable in the future or unavailable on terms that we believe
are economically acceptable. No assurance can be given that we will be able to maintain insurance in the future at rates that we consider reasonable and we
may  elect  to  maintain  minimal  or  no  insurance  coverage.  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. The occurrence of a significant
event, not fully insured against, could have a material adverse effect on our financial condition and results of operations.

Generally, we also require our third party vendors to sign master service agreements in which they agree to indemnify us for injuries and deaths of

the service provider’s employees as well as contractors and subcontractors hired by the service provider.

Employees

As of December 31, 2019, we had approximately 712 full time employees. None of our employees are represented by labor unions or covered by any
collective bargaining agreements. We also hire independent contractors and consultants involved in land, technical, regulatory and other disciplines to assist
our full time employees.

Facilities

Our corporate headquarters is located in Midland, Texas. We also lease additional office space in Birmingham, Alabama, Houston, Texas, Midland,

Texas and Oklahoma City, Oklahoma. We believe that our facilities are adequate for our current operations.

Availability of Company Reports

Our annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K, and all amendments to those reports are available
free  of  charge  on  the  Investor  Relations  page  of  our  website  at  www.diamondbackenergy.com  as  soon  as  reasonably  practicable  after  such  material  is
electronically filed with, or furnished to, the SEC. Information contained on, or connected to, our website is not incorporated by reference into this Form 10-K
and should not be considered part of this or any other report that we file with or furnish to the SEC.

ITEM 1A. RISK FACTORS

The nature of our business activities subjects us to certain hazards and risks. The following is a summary of some of the material risks relating to our
business activities. Other risks are described in Item 1. “Business and Properties” and Item 7A. “Quantitative and Qualitative Disclosures About Market
Risk.”  These  risks  are  not  the  only  risks  we  face.  We  could  also  face  additional  risks  and  uncertainties  not  currently  known  to  the  Company  or  that  we
currently deem to be immaterial. If any of these risks actually occurs, it could materially harm our business, financial condition or results of operations and
the trading price of our shares could decline.

Risks Related to the Oil and Natural Gas Industry and Our Business

Market conditions for oil and natural gas, and particularly volatility in prices for oil and natural gas, have in the past adversely affected, and may in the
future adversely affect, our revenue, cash flows, profitability, growth, production and the present value of our estimated reserves.

Our revenues, operating results, profitability, future rate of growth and the carrying value of our oil and natural gas properties depend significantly

upon the prevailing prices for oil and natural gas. Historically, oil and natural gas prices have

26

Table of Contents

been  volatile  and  are  subject  to  fluctuations  in  response  to  changes  in  supply  and  demand,  market  uncertainty  and  a  variety  of  additional  factors  that  are
beyond our control, including:

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

the domestic and foreign supply of 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 price and quantity of foreign imports;

political and economic conditions in oil producing countries, including the Middle East, Africa, South America and Russia;

the ability of members of the Organization of Petroleum Exporting Countries to agree to and maintain oil price and production controls;

speculative trading in crude oil and natural gas derivative contracts;

the level of consumer product demand;

weather conditions and other natural disasters;

risks associated with operating drilling rigs;

technological advances affecting energy consumption;

the price and availability of alternative fuels;

domestic and foreign governmental regulations and taxes;

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

global or national health concerns, including the outbreak of pandemic or contagious disease, such as the coronavirus;

the proximity, cost, availability and capacity of oil and natural gas pipelines and other transportation facilities; 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. During the past five years, the posted price for West Texas intermediate light sweet crude oil, which we refer to as WTI Futures Contract 1 price for
crude oil has ranged from a low of $26.21 per barrel, or Bbl, in February 2016 to a high of $76.41 per Bbl in October 2018. The Natural Gas Futures Contract
1 price spot market price of natural gas has ranged from a low of $1.64 per MMBtu in March 2016 to a high of $4.84 per MMBtu in November 2018. During
2019, WTI Futures Contract 1 prices ranged from $46.54 to $66.30 per Bbl and the Natural Gas Futures Contract 1 spot market price of natural gas ranged
from $2.07 to $3.59 per MMBtu. On January 31, 2020, the WTI Futures Contract 1 posted price for crude oil was $51.56 per Bbl and the Natural Gas Futures
Contract 1 spot market price of natural gas was $1.84 per MMBtu, representing decreases of 22% and 49%, respectively, from the high of $66.30 per Bbl of
oil  and  $3.59  per  MMBtu  for  natural  gas  during  2019.  In  response  to  recent  volatility  in  commodity  prices,  many  producers  have  reduced  their  capital
expenditure budgets. If the prices of oil and natural gas decline further, our operations, financial condition and level of expenditures for the development of
our oil and natural gas reserves may be materially and adversely affected.

In addition, lower oil and natural gas prices may reduce the amount of oil and natural gas that we can produce economically. This may result in our
having to make substantial downward adjustments to our estimated proved reserves. If this occurs or if our production estimates change or our exploration or
development activities are curtailed, full cost accounting rules may require us to write down, as a non-cash charge to earnings, the carrying value of our oil
and natural gas properties. Reductions in our

27

Table of Contents

reserves could also negatively impact the borrowing base under our revolving credit facility, which could further limit our liquidity and ability to conduct
additional exploration and development activities.

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, energy costs, geopolitical issues, inflation, the availability and cost of credit, the European, Asian and the
United States financial markets have in the past contributed, and may in the future contribute, to economic uncertainty and diminished expectations for the
global economy. In addition, continued hostilities in the Middle East, the occurrence or threat of terrorist attacks in the United States or other countries and
global  or  national  health  concerns  could  adversely  affect  the  global  economy.  These  factors,  combined  with  volatility  in  commodity  prices,  business  and
consumer confidence and unemployment rates, may precipitate an economic slowdown. Concerns about global economic growth may have an 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,  which  could  impact  the  price  at  which  we  can  sell  our  production,  affect  the  ability  of  our  vendors,  suppliers  and  customers  to
continue operations and ultimately adversely impact our results of operations, liquidity and financial condition.

A significant portion of our net leasehold acreage is undeveloped, and that acreage may not ultimately be developed or become commercially productive,
which could cause us to lose rights under our leases as well as have a material adverse effect on our oil and natural gas reserves and future production
and, therefore, our future cash flow and income.

A significant portion of our net leasehold acreage is undeveloped, or acreage on which wells have not been drilled or completed to a point that would
permit the production of commercial quantities of oil and natural gas regardless of whether such acreage contains proved reserves. In addition, many of our
oil and natural gas leases require us to drill wells that are commercially productive, and if we are unsuccessful in drilling such wells, we could lose our rights
under such leases. Our future oil and natural gas reserves and production and, therefore, our future cash flow and income are highly dependent on successfully
developing our undeveloped leasehold acreage.

Our development and exploration operations and our ability to complete acquisitions require substantial capital and we may be unable to obtain needed
capital or financing on satisfactory terms or at all, which could lead to a loss of properties and a decline in our oil and natural gas reserves.

The oil and natural gas industry is capital intensive. We make and expect to continue to make substantial capital expenditures in our business and
operations  for  the  exploration  for  and  development,  production  and  acquisition  of  oil  and  natural  gas  reserves.  In  2019,  our  total  capital  expenditures,
including  expenditures  for  leasehold  acquisitions,  drilling  and  infrastructure,  were  approximately  $3.1  billion.  Our  2020  capital  budget  for  drilling,
completion and infrastructure, including investments in water disposal infrastructure and gathering line projects, is currently estimated to be approximately
$2.8 billion to $3.0 billion, representing an increase of 1% over our 2019 capital budget. Since completing our initial public offering in October 2012, we
have  financed  capital  expenditures  primarily  with  borrowings  under  our  revolving  credit  facility,  cash  generated  by  operations  and  the  net  proceeds  from
public offerings of our common stock and the senior notes.

We intend to finance our future capital expenditures with cash flow from operations, proceeds from offerings of our debt and equity securities and

borrowings under our revolving credit facility. Our cash flow from operations and access to capital are subject to a number of variables, including:

•

•

•

•

•

our proved reserves;

the volume of oil and natural gas we are able to produce from existing wells;

the prices at which our oil and natural gas are sold;

our ability to acquire, locate and produce economically new reserves; and

our ability to borrow under our credit facility.

We cannot assure you that our operations and other capital resources will provide cash in sufficient amounts to maintain planned or future levels of
capital  expenditures.  Further,  our  actual  capital  expenditures  in  2020  could  exceed  our  capital  expenditure  budget.  In  the  event  our  capital  expenditure
requirements at any time are greater than the amount of capital we have available, we could be required to seek additional sources of capital, which may
include traditional reserve base borrowings, debt

28

Table of Contents

financing, joint venture partnerships, production payment financings, sales of assets, offerings of debt or equity securities or other means. We cannot assure
you that we will be able to obtain debt or equity financing on terms favorable to us, or at all.

If we are unable to fund our capital requirements, we may be required to curtail our operations relating to the exploration and development of our
prospects,  which  in  turn  could  lead  to  a  possible  loss  of  properties  and  a  decline  in  our  oil  and  natural  gas  reserves,  or  we  may  be  otherwise  unable  to
implement our development plan, complete acquisitions or take advantage of business opportunities or respond to competitive pressures, any of which could
have  a  material  adverse  effect  on  our  production,  revenues  and  results  of  operations.  In  addition,  a  delay  in  or  the  failure  to  complete  proposed  or  future
infrastructure projects could delay or eliminate potential efficiencies and related cost savings.

Our success depends on finding, developing or acquiring additional reserves.

Our future success depends upon our ability to find, develop or acquire additional oil and natural gas reserves that are economically recoverable. Our
proved  reserves  will  generally  decline  as  reserves  are  depleted,  except  to  the  extent  that  we  conduct  successful  exploration  or  development  activities  or
acquire properties containing proved reserves, or both. To increase reserves and production, we undertake development, exploration and other replacement
activities or use third parties to accomplish these activities. We have made, and expect to make in the future, substantial capital expenditures in our business
and operations for the development, production, exploration and acquisition of oil and natural gas reserves. We may not have sufficient resources to acquire
additional  reserves  or  to  undertake  exploration,  development,  production  or  other  replacement  activities,  such  activities  may  not  result  in  significant
additional  reserves  and  we  may  not  have  success  drilling  productive  wells  at  low  finding  and  development  costs.  If  we  are  unable  to  replace  our  current
production, the value of our reserves will decrease, and our business, financial condition and results of operations would be adversely affected. Furthermore,
although our revenues may increase if prevailing oil and natural gas prices increase significantly, our finding costs for additional reserves could also increase.

Our failure to successfully identify, complete and integrate pending and future acquisitions of properties or businesses could reduce our earnings and
slow our growth.

There is intense competition for acquisition opportunities in our industry. The successful acquisition of producing properties requires an assessment

of several factors, including:

•

•

•

•

recoverable reserves;

future oil and natural gas prices and their applicable differentials;

operating costs; and

potential environmental and other liabilities.

The accuracy of these assessments is inherently uncertain and we may not be able to identify attractive acquisition opportunities. In connection with
these assessments, we perform a review of the subject properties that we believe to be generally consistent with industry practices. Our review will not reveal
all existing or potential problems nor will it permit us to become sufficiently familiar with the properties to assess fully their deficiencies and capabilities.
Inspections may not always be performed on every well, and environmental problems, such as groundwater contamination, are not necessarily observable
even when an inspection is undertaken. Even when problems are identified, the seller may be unwilling or unable to provide effective contractual protection
against all or part of the problems. Even if we do identify attractive acquisition opportunities, we may not be able to complete the acquisition or do so on
commercially acceptable terms.

Competition for acquisitions may increase the cost of, or cause us to refrain from, completing acquisitions. Our ability to complete acquisitions is
dependent upon, among other things, our ability to obtain debt and equity financing and, in some cases, regulatory approvals. Further, these acquisitions may
be  in  geographic  regions  in  which  we  do  not  currently  operate,  which  could  result  in  unforeseen  operating  difficulties  and  difficulties  in  coordinating
geographically  dispersed  operations,  personnel  and  facilities.  In  addition,  if  we  enter  into  new  geographic  markets,  we  may  be  subject  to  additional  and
unfamiliar  legal  and  regulatory  requirements.  Compliance  with  regulatory  requirements  may  impose  substantial  additional  obligations  on  us  and  our
management, cause us to expend additional time and resources in compliance activities and increase our exposure to penalties or fines for non-compliance
with  such  additional  legal  requirements.  Further,  the  success  of  any  completed  acquisition  will  depend  on  our  ability  to  integrate  effectively  the  acquired
business into our existing operations. The process of integrating acquired businesses may involve unforeseen difficulties and may require a disproportionate
amount of our managerial and financial resources. In addition, possible future acquisitions may be larger and for purchase prices significantly higher than
those paid for earlier acquisitions.

29

Table of Contents

No assurance can be given that we will be able to identify additional suitable acquisition opportunities, negotiate acceptable terms, obtain financing
for  acquisitions  on  acceptable  terms  or  successfully  acquire  identified  targets.  Our  failure  to  achieve  consolidation  savings,  to  integrate  the  acquired
businesses and assets into our existing operations successfully or to minimize any unforeseen operational difficulties could have a material adverse effect on
our  financial  condition  and  results  of  operations.  The  inability  to  effectively  manage  the  integration  of  acquisitions,  including  our  recently  completed  and
pending  acquisitions,  could  reduce  our  focus  on  subsequent  acquisitions  and  current  operations,  which,  in  turn,  could  negatively  impact  our  earnings  and
growth. Our financial position and results of operations may fluctuate significantly from period to period, based on whether or not significant acquisitions are
completed in particular periods.

Properties we acquire may not produce as projected, and we may be unable to determine reserve potential, identify liabilities associated with the properties
that we acquire or obtain protection from sellers against such liabilities.

Acquiring oil and natural gas properties requires us to assess reservoir and infrastructure characteristics, including recoverable reserves, development
and  operating  costs  and  potential  environmental  and  other  liabilities.  Such  assessments  are  inexact  and  inherently  uncertain.  In  connection  with  the
assessments, we perform a review of the subject properties, but such a review will not necessarily reveal all existing or potential problems. In the course of
our due diligence, we may not inspect every well or pipeline. We cannot necessarily observe structural and environmental problems, such as pipe corrosion,
when an inspection is made. We may not be able to obtain contractual indemnities from the seller for liabilities created prior to our purchase of the property.
We may be required to assume the risk of the physical condition of the properties in addition to the risk that the properties may not perform in accordance
with our expectations.

We may incur losses as a result of title defects in the properties in which we invest.

It is our practice in acquiring oil and natural gas leases or interests not to incur the expense of retaining lawyers to examine the title to the mineral
interest.  Rather,  we  rely  upon  the  judgment  of  oil  and  gas  lease  brokers  or  landmen  who  perform  the  fieldwork  in  examining  records  in  the  appropriate
governmental office before attempting to acquire a lease in a specific mineral interest. The existence of a material title deficiency can render a lease worthless
and can adversely affect our results of operations and financial condition.

Prior to the drilling of an oil or natural gas well, however, it is the normal practice in our industry for the person or company acting as the operator of
the well to obtain a preliminary title review to ensure there are no obvious defects in title to the well. Frequently, as a result of such examinations, certain
curative work must be done to correct defects in the marketability of the title, and such curative work entails expense. Our failure to cure any title defects may
delay or prevent us from utilizing the associated mineral interest, which may adversely impact our ability in the future to increase production and reserves.
Additionally,  undeveloped  acreage  has  greater  risk  of  title  defects  than  developed  acreage.  If  there  are  any  title  defects  or  defects  in  the  assignment  of
leasehold rights in properties in which we hold an interest, we will suffer a financial loss.

Our project areas, which are in various stages of development, may not yield oil or natural gas in commercially viable quantities.

Our project areas are in various stages of development, ranging from project areas with current drilling or production activity to project areas that
consist of recently acquired leasehold acreage or that have limited drilling or production history. If future wells or the wells in the process of being completed
do not produce sufficient revenues to return a profit or if we drill dry holes in the future, our business may be materially affected.

Our identified potential drilling locations, which are part of our anticipated future drilling plans, are susceptible to uncertainties that could materially
alter the occurrence or timing of their drilling.

At an assumed price of approximately $60.00 per Bbl WTI, we currently have approximately 12,310 gross (8,141 net) identified economic potential
horizontal  drilling  locations  in  multiple  horizons  on  our  acreage.  As  of  December  31,  2019,  only  477  of  our  gross  identified  potential  horizontal  drilling
locations were attributed to proved reserves. These drilling locations, including those without proved undeveloped reserves, represent a significant part of our
growth strategy. Our ability to drill and develop these locations depends on a number of uncertainties, including the availability of capital, construction of
infrastructure, inclement weather, regulatory changes and approvals, oil and natural gas prices, costs, drilling results and the availability of water. Further, our
identified potential drilling locations are in various stages of evaluation, ranging from locations that are ready to drill to locations that will require substantial
additional interpretation. In addition, we have identified approximately 3,382 horizontal drilling locations in intervals in which we have drilled very few or no
wells, which are necessarily more speculative and based on results from other operators whose acreage may not be consistent with ours. We cannot predict in
advance of drilling and testing whether any particular drilling location will yield oil or natural gas in sufficient quantities to recover drilling or

30

 
Table of Contents

completion  costs  or  to  be  economically  viable.  The  use  of  technologies  and  the  study  of  producing  fields  in  the  same  area  will  not  enable  us  to  know
conclusively prior to drilling whether oil or natural gas will be present or, if present, whether oil or natural gas will be present in sufficient quantities to be
economically  viable.  Even  if  sufficient  amounts  of  oil  or  natural  gas  exist,  we  may  damage  the  potentially  productive  hydrocarbon  bearing  formation  or
experience mechanical difficulties while drilling or completing the well, possibly resulting in a reduction in production from the well or abandonment of the
well. If we drill additional wells that we identify as dry holes in our current and future drilling locations, our drilling success rate may decline and materially
harm our business. Through December 31, 2019, we are the operator of, have participated in, or have acquired a total of 1,770 horizontal wells completed on
our acreage, we cannot assure you that the analogies we draw from available data from these or other wells, more fully explored locations or producing fields
will be applicable to our drilling locations. Further, initial production rates reported by us or other operators in the Permian Basin may not be indicative of
future or long-term production rates. Because of these uncertainties, we do not know if the potential drilling locations we have identified will ever be drilled
or if we will be able to produce oil or natural gas from these or any other potential drilling locations. As such, our actual drilling activities may materially
differ from those presently identified, which could adversely affect our business.

Multi-well pad drilling may result in volatility in our operating results.

We utilize multi-well pad drilling where practical. Because wells drilled on a pad are not brought into production until all wells on the pad are drilled
and completed and the drilling rig is moved from the location, multi-well pad drilling delays the commencement of production, which may cause volatility in
our quarterly operating results.

Our  acreage  must  be  drilled  before  lease  expiration,  generally  within  three  to  five  years,  in  order  to  hold  the  acreage  by  production.  In  a  highly
competitive market for acreage, failure to drill sufficient wells to hold acreage may result in a substantial lease renewal cost or, if renewal is not feasible,
loss of our lease and prospective drilling opportunities.

Leases on oil and natural gas properties typically have a term of three to five years, after which they expire unless, prior to expiration, production is
established within the spacing units covering the undeveloped acres. As of December 31, 2019, we had leases representing 42,421 net acres expiring in 2020,
7,626 net acres expiring in 2021, 2,387 net acres expiring in 2022, 4,919 net acres expiring in 2023 and no net acres expiring in 2024. The cost to renew such
leases  may  increase  significantly,  and  we  may  not  be  able  to  renew  such  leases  on  commercially  reasonable  terms  or  at  all.  Any  reduction  in  our  current
drilling  program,  either  through  a  reduction  in  capital  expenditures  or  the  unavailability  of  drilling  rigs,  could  result  in  the  loss  of  acreage  through  lease
expirations. In addition, in order to hold our current leases expiring in 2020, we will need to operate at least a one-rig program. We cannot assure you that we
will have the liquidity to deploy these rigs in this time frame, or that commodity prices will warrant operating such a drilling program. Any such losses of
leases could materially and adversely affect the growth of our asset basis, cash flows and results of operations.

We have entered into fixed price swap contracts, fixed price basis swap contracts, double-up swap contracts and three-way collars with corresponding put,
short put and call options and may in the future enter into forward sale contracts or additional fixed price swap, fixed price basis swap, double-up swap
derivatives or three-way collars for a portion of our production. Although we have hedged a portion of our estimated 2020 and 2021 production, we may
still be adversely affected by continuing and prolonged declines in the price of oil.

We use fixed price swap contracts, fixed price basis swap contracts, double-up swap contracts and three-way collars with corresponding put, short
put and call options to reduce price volatility associated with certain of our oil and natural gas sales. Under these swap contracts, we receive a fixed price per
barrel of oil and pay a floating market price per barrel of oil to the counterparty based on NYMEX WTI pricing. The fixed-price payment and the floating-
price payment are offset, resulting in a net amount due to or from the counterparty. Under our three-way collar contracts, the counterparty is required to make
a payment to us if the settlement price for any settlement period is less than the ceiling price to a maximum of the difference between the floor price and the
short put price.  We are required to make a payment to the counterparty if the settlement price for any settlement period is greater than the ceiling price. If the
settlement price is between the floor and the ceiling price, there is no payment required.

To  the  extent  that  the  prices  of  oil  and  natural  gas  remain  at  current  levels  or  decline  further,  we  may  not  be  able  to  economically  hedge  future
production  at  the  same  level  as  our  current  hedges,  and  our  results  of  operations  and  financial  condition  may  be  negatively  impacted.  For  additional
information  regarding  our  outstanding  derivative  contracts  as  of  December  31,  2019,  see  Note  15—Derivatives  to  our  consolidated  financial  statements
included elsewhere in this report.

Table of Contents

Our derivative transactions expose us to counterparty credit risk.

By using derivative instruments to economically hedge exposure to changes in commodity prices, we expose ourselves to credit risk. Credit risk is
the failure of the counterparty to perform under the terms of the derivative contract. When the fair value of a derivative contract is positive, the counterparty
owes us, which creates credit risk. We do not require collateral from our counterparties. We have entered into derivative instruments only with counterparties
that are also lenders in our credit facility and have been deemed an acceptable credit risk by us.

If production from our Permian Basin acreage decreases due to decreased developmental activities, production related difficulties or otherwise, we may
fail  to  meet  our  obligations  to  deliver  specified  quantities  of  oil  under  our  oil  purchase  contract,  which  will  result  in  deficiency  payments  to  the
counterparty and may have an adverse effect on our operations.

We are a party to long-term crude oil agreements with Trafigura, Plains, Shell and Vitol under which, subject to certain terms and conditions, we are
obligated to deliver specified quantities of oil to such companies. Our maximum delivery obligation under these agreements varies for different periods and
depends in some cases upon certain conditions, such as the in-service dates for the Gray Oak pipeline and the EPIC pipeline as described in this report. See
“Business  and  Properties—Marketing  and  Customers”  above.  If  production  from  our  Permian  Basin  acreage  decreases  due  to  decreased  developmental
activities, as a result of the low commodity price environment, production related difficulties or otherwise, we may be unable to meet our obligations under
our oil purchase agreements, which may result in deficiency payments to certain counterparties or a default under such agreements and may have an adverse
effect on our company.

The inability of one or more of our customers to meet their obligations may adversely affect our financial results.

In addition to credit risk related to receivables from commodity derivative contracts, our principal exposure to credit risk is through receivables from
joint interest owners on properties we operate (approximately $186 million at December 31, 2019) and receivables from purchasers of our oil and natural gas
production (approximately $429 million at December 31, 2019). Joint interest receivables arise from billing entities that own partial interests in the wells we
operate. These entities participate in our wells primarily based on their ownership in leases on which we wish to drill. We are generally unable to control
which co-owners participate in our wells.

We are also subject to credit risk due to the concentration of our oil and natural gas receivables with several significant customers. For the year ended
December 31, 2019, three purchasers each accounted for more than 10% of our revenue: Shell (27%); Plains (23%); and Vitol (15%).  For  the  year  ended
December 31, 2018, three purchasers each accounted for more than 10% of our revenue: Shell (26%); Koch (15%); and Occidental Energy Marketing Inc.
(11%). For the year ended December 31, 2017, three purchasers each accounted for more than 10% of our revenue: Shell (31%); Koch (19%); and Enterprise
Crude Oil LLC (11%). No other customer accounted for more than 10% of our revenue during these periods. This concentration of customers may impact our
overall credit risk in that these entities may be similarly affected by changes in economic and other conditions. Current economic circumstances may further
increase these risks. We do not require our customers to post collateral. The inability or failure of our significant customers or joint working interest owners to
meet their obligations to us or their insolvency or liquidation may materially adversely affect our financial results.

Our method of accounting for investments in oil and natural gas properties may result in impairment of asset value.

We  account  for  our  oil  and  natural  gas  producing  activities  using  the  full  cost  method  of  accounting.  Accordingly,  all  costs  incurred  in  the
acquisition, exploration and development of proved oil and natural gas properties, including the costs of abandoned properties, dry holes, geophysical costs
and annual lease rentals are capitalized.  We  also  capitalize  direct  operating  costs  for  services  performed  with  internally  owned  drilling  and  well  servicing
equipment. All  general  and  administrative  corporate  costs  unrelated  to  drilling  activities  are  expensed  as  incurred.  Sales  or  other  dispositions  of  oil  and
natural gas properties are accounted for as adjustments to capitalized costs, with no gain or loss recorded unless the ratio of cost to proved reserves would
significantly change. Income from services provided to working interest owners of properties in which we also own an interest, to the extent they exceed
related  costs  incurred,  are  accounted  for  as  reductions  of  capitalized  costs  of  oil  and  natural  gas  properties.  Depletion  of  evaluated  oil  and  natural  gas
properties is computed on the units of production method, whereby capitalized costs plus estimated future development costs are amortized over total proved
reserves. The average depletion rate per barrel equivalent unit of production was $13.54, $12.62 and $11.11 for the years ended December 31, 2019, 2018 and
2017, respectively. Depreciation, depletion and amortization expense for oil and natural gas properties for the years ended December 31, 2019, 2018 and 2017
was $1.4 billion, $595 million and $321 million, respectively.

The net capitalized costs of proved oil and natural gas properties are subject to a full cost ceiling limitation in which the costs are not allowed to

exceed their related estimated future net revenues discounted at 10%. To the extent capitalized costs of

32

Table of Contents

evaluated oil and natural gas properties, net of accumulated depreciation, depletion, amortization and impairment, exceed the discounted future net revenues
of  proved  oil  and  natural  gas  reserves,  the  excess  capitalized  costs  are  charged  to  expense.  Beginning  December  31,  2009,  we  have  used  the  unweighted
arithmetic average first day of the month price for oil and natural gas for the 12-month period preceding the calculation date in estimating discounted future
net revenues.

An impairment on proved oil and natural gas properties of $790 million was recorded for the year ended December 31, 2019. No impairments on
proved oil and natural gas properties were recorded for the years ended December 31, 2018 and 2017. See Item 7. “Management’s Discussion and Analysis of
Financial Condition and Results of Operations—Critical Accounting Policies and Estimates—Method of accounting for oil and natural gas properties” for a
more detailed description of our method of accounting.

Our  estimated  reserves  and  EURs  are  based  on  many  assumptions  that  may  turn  out  to  be  inaccurate.  Any  material  inaccuracies  in  these  reserve
estimates or underlying assumptions will materially affect the quantities and present value of our reserves.

Oil and natural gas reserve engineering is not an exact science and requires subjective estimates of underground accumulations of oil and natural gas
and  assumptions  concerning  future  oil  and  natural  gas  prices,  production  levels,  ultimate  recoveries  and  operating  and  development  costs.  As  a  result,
estimated quantities of proved reserves, projections of future production rates and the timing of development expenditures may be incorrect. Our historical
estimates of proved reserves as of December 31, 2019, 2018 and 2017  (which  include  those  attributable  to  Viper)  are  based  on  reports  prepared  by  Ryder
Scott, which conducted a well-by-well review of all our properties for the periods covered by its reserve reports using information provided by us. The EURs
for our horizontal wells are based on management’s internal estimates. Over time, we may make material changes to reserve estimates taking into account the
results of actual drilling, testing and production. Also, certain assumptions regarding future oil and natural gas prices, production levels and operating and
development costs may prove incorrect. Any significant variance from these assumptions to actual figures could greatly affect our estimates of reserves, the
economically recoverable quantities of oil and natural gas attributable to any particular group of properties, the classifications of reserves based on risk of
recovery and estimates of future net cash flows. A substantial portion of our reserve estimates are made without the benefit of a lengthy production history,
which are less reliable than estimates based on a lengthy production history. Numerous changes over time to the assumptions on which our reserve estimates
are based, as described above, often result in the actual quantities of oil and natural gas that we ultimately recover being different from our reserve estimates.
Reserve estimates do not include any value for probable or possible reserves that may exist, nor do they include any value for unproved undeveloped acreage.
The reserve estimates represent our net revenue interest in our properties.

The  estimates  of  reserves  as  of  December  31,  2019,  2018  and  2017  included  in  this  report  were  prepared  using  an  average  price  equal  to  the
unweighted  arithmetic  average  of  hydrocarbon  prices  received  on  a  field-by-field  basis  on  the  first  day  of  each  month  within  the  12-month  periods
December 31, 2019, 2018 and 2017, respectively, in accordance with the SEC guidelines applicable to reserve estimates for such periods.

The timing of both our production and our incurrence of costs in connection with the development and production of oil and natural gas properties

will affect the timing of actual future net cash flows from proved reserves.

The  standardized  measure  of  our  estimated  proved  reserves  and  our  PV-10  are  not  necessarily  the  same  as  the  current  market  value  of  our  estimated
proved oil reserves.

The present value of future net cash flow from our proved reserves, or standardized measure, and our related PV-10 calculation, may not represent
the current market value of our estimated proved oil reserves. In accordance with SEC requirements, we base the estimated discounted future net cash flow
from our estimated proved reserves on the 12-month average oil index prices, calculated as the unweighted arithmetic average for the first-day-of-the-month
price for each month and costs in effect as of the date of the estimate, holding the prices and costs constant throughout the life of the properties.

Actual future prices and costs may differ materially from those used in the net present value estimate, and future net present value estimates using
then current prices and costs may be significantly less than current estimates. In addition, the 10% discount factor we use when calculating discounted future
net  cash  flow  for  reporting  requirements  in  compliance  with  the  Financial  Accounting  Standard  Board  Codification  932,  “Extractive  Activities—Oil  and
Gas,” may not be the most appropriate discount factor based on interest rates in effect from time to time and risks associated with us or the oil and natural gas
industry in general.

SEC rules could limit our ability to book additional proved undeveloped reserves in the future.

SEC rules require that, subject to limited exceptions, proved undeveloped reserves may only be booked if they relate to wells scheduled to be drilled
within five years after the date of booking. This requirement has limited and may continue to limit our ability to book additional proved undeveloped reserves
as we pursue our drilling program. Moreover, we may be required to write down our proved undeveloped reserves if we do not drill those wells within the
required five-year timeframe because they have become uneconomic or otherwise.

The development of our proved undeveloped reserves may take longer and may require higher levels of capital expenditures than we currently anticipate.

Approximately 33% of our total estimated proved reserves as of December 31, 2019, were proved undeveloped reserves and may not be ultimately
developed  or  produced.  Recovery  of  proved  undeveloped  reserves  requires  significant  capital  expenditures  and  successful  drilling  operations.  The  reserve
data included in the reserve reports of our independent petroleum engineers assume that substantial capital expenditures are required to develop such reserves.
We cannot be certain that the estimated costs of the development of these reserves are accurate, that development will occur as scheduled or that the results of
such development will be as estimated. Delays in the development of our reserves, increases in costs to drill and develop such reserves, or further decreases in
commodity prices will reduce the future net revenues of our estimated proved undeveloped reserves and may result in some projects becoming uneconomical.
In addition, delays in the development of reserves could force us to reclassify certain of our proved reserves as unproved reserves.

Our producing properties are located in the Permian Basin of West Texas, making us vulnerable to risks associated with operating in a single geographic
area. In addition, we have a large amount of proved reserves attributable to a small number of producing horizons within this area.

All of our producing properties are currently geographically concentrated in the Permian Basin of West Texas. 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 this area caused
by governmental regulation, processing or transportation capacity constraints, availability of equipment, facilities, personnel or services market limitations or
interruption of the processing or transportation of crude oil, natural gas or natural gas liquids. 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 conditions to
occur  with  greater  frequency  or  magnify  the  effects  of  these  conditions.  Due  to  the  concentrated  nature  of  our  portfolio  of  properties,  a  number  of  our
properties could experience any of the same conditions at the same time, resulting in a relatively greater impact on our results of operations than they might
have  on  other  companies  that  have  a  more  diversified  portfolio  of  properties.  Such  delays  or  interruptions  could  have  a  material  adverse  effect  on  our
financial condition and results of operations.

In addition to the geographic concentration of our producing properties described above, as of December 31, 2019, all of our proved reserves were
attributable to the Wolfberry play in the Midland Basin. This concentration of assets within a small number of producing horizons exposes us to additional
risks, such as changes in field-wide rules and regulations that could cause us to permanently or temporarily shut-in all of our wells within a field.

We depend upon several significant purchasers for the sale of most of our oil and natural gas production. The loss of one or more of these purchasers
could, among other factors, limit our access to suitable markets for the oil and natural gas we produce.

The availability of a ready market for any oil and/or natural gas we produce depends on numerous factors beyond the control of our management,
including but not limited to the extent of domestic production and imports of oil, the proximity and capacity of natural gas pipelines, the availability of skilled
labor,  materials  and  equipment,  the  effect  of  state  and  federal  regulation  of  oil  and  natural  gas  production  and  federal  regulation  of  natural  gas  sold  in
interstate commerce. In addition, we depend upon several significant purchasers for the sale of most of our oil and natural gas production. For the year ended
December 31, 2019, three purchasers each accounted for more than 10% of our revenue: Shell (27%); Plains (23%); and Vitol (15%).  For  the  year  ended
December 31, 2018, three purchasers each accounted for more than 10% of our revenue: Shell (26%); Koch (15%); and Occidental Energy Marketing Inc.
(11%). For the year ended December 31, 2017, three purchasers each accounted for more than 10% of our revenue: Shell (31%); Koch (19%); and Enterprise
Crude Oil LLC (11%). No other customer accounted for more than 10% of our revenue during these periods. We cannot assure you that we will continue to
have ready access to suitable markets for our future oil and natural gas production. The loss of one or more of these customers, and our inability to sell our
production to other customers on terms we consider acceptable, could materially and adversely affect our business, financial condition, results of operations
and cash flow.

The unavailability, high cost or shortages of rigs, equipment, raw materials, supplies, oilfield services or personnel may restrict our operations.

The  oil  and  natural  gas  industry  is  cyclical,  which  can  result  in  shortages  of  drilling  rigs,  equipment,  raw  materials  (particularly  sand  and  other
proppants), supplies and personnel. When shortages occur, the costs and delivery times of rigs, equipment and supplies increase and demand for, and wage
rates of, qualified drilling rig crews also rise with increases in demand. We cannot predict whether these conditions will exist in the future and, if so, what
their timing and duration will be. In accordance with customary industry practice, we rely on independent third party service providers to provide most of the
services necessary to drill new wells. If we are unable to secure a sufficient number of drilling rigs at reasonable costs, our financial condition and results of
operations could suffer, and we may not be able to drill all of our acreage before our leases expire. In addition, we do not have long-term contracts securing
the use of our existing rigs, and the operator of those rigs may choose to cease providing services to us. Shortages of drilling rigs, equipment, raw materials
(particularly sand and other proppants), supplies, personnel, trucking services, tubulars, fracking and completion services and production equipment could
delay or restrict our exploration and development operations, which in turn could impair our financial condition and results of operations.

Our  operations  are  substantially  dependent  on  the  availability  of  water.  Restrictions  on  our  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 deep shale oil and natural gas production during both the drilling and hydraulic fracturing processes. Historically,
we have been able to purchase water from local land owners for use in our operations. Over the past several years, Texas has experienced extreme drought
conditions.  As  a  result  of  this  severe  drought,  some  local  water  districts  have  begun  restricting  the  use  of  water  subject  to  their  jurisdiction  for  hydraulic
fracturing to protect local water supply. If we are unable to obtain water to use in our operations from local sources, or we are unable to effectively utilize
flowback water, we may be unable to economically drill for or produce oil and natural gas, which could have an adverse effect on our financial condition,
results of operations and cash flows.

We may have difficulty managing growth in our business, which could adversely affect our financial condition and results of operations.

Our business operations have grown substantially since our initial public offering in October 2012 and we expect our business operations to continue
to grow in the future. As we expand our activities and increase the number of projects we are evaluating or in which we participate, there will be additional
demands on our financial, technical, operational and management resources. The failure to continue to upgrade our technical, administrative, operating and
financial control systems or the occurrences of unexpected expansion difficulties, including the failure to recruit and retain experienced managers, geologists,
engineers and other professionals in the oil and natural gas industry, could have a material adverse effect on our business, financial condition and results of
operations and our ability to timely execute our business plan.

We have incurred losses from operations during certain periods since our inception and may do so in the future.

Our  development  of  and  participation  in  an  increasingly  larger  number  of  drilling  locations  has  required  and  will  continue  to  require  substantial
capital expenditures. The uncertainty and risks described in this report may impede our ability to economically find, develop and acquire oil and natural gas
reserves. As a result, we may not be able to achieve or sustain profitability or positive cash flows from our operating activities in the future.

Part  of  our  strategy  involves  drilling  in  existing  or  emerging  shale  plays  using  the  latest  available  horizontal  drilling  and  completion  techniques;
therefore, the results of our planned exploratory drilling in these plays are subject to risks associated with drilling and completion techniques and drilling
results may not meet our expectations for reserves or production.

Our operations involve utilizing the latest drilling and completion techniques as developed by us and our service providers. Risks that we face while
drilling  include,  but  are  not  limited  to,  landing  our  well  bore  in  the  desired  drilling  zone,  staying  in  the  desired  drilling  zone  while  drilling  horizontally
through  the  formation,  running  our  casing  the  entire  length  of  the  well  bore  and  being  able  to  run  tools  and  other  equipment  consistently  through  the
horizontal well bore. Risks that we face while completing our wells include, but are not limited to, being able to fracture stimulate the planned number of
stages, being able to run tools the entire length of the well bore during completion operations and successfully cleaning out the well bore after completion of
the final fracture stimulation stage. In addition, to the extent we engage in horizontal drilling, those activities may adversely affect our ability to successfully
drill in one or more of our identified vertical drilling locations. Furthermore, certain of the new techniques we are adopting, such as infill drilling and multi-
well pad drilling, may cause irregularities or interruptions in production due to, in the case of infill drilling, offset wells being shut in and, in the case of multi-
well pad drilling, the time required to drill and

35

Table of Contents

complete multiple wells before any such wells begin producing. The results of our drilling in new or emerging formations are more uncertain initially than
drilling  results  in  areas  that  are  more  developed  and  have  a  longer  history  of  established  production.  Newer  or  emerging  formations  and  areas  often  have
limited or no production history and consequently we are less able to predict future drilling results in these areas.

Ultimately, the success of these drilling and completion techniques can only be evaluated over time as more wells are drilled and production profiles
are established over a sufficiently long time period. If our drilling results are less than anticipated or we are unable to execute our drilling program because of
capital constraints, lease expirations, access to gathering systems, and/or declines in natural gas and oil prices, the return on our investment in these areas may
not  be  as  attractive  as  we  anticipate.  Further,  as  a  result  of  any  of  these  developments  we  could  incur  material  write-downs  of  our  oil  and  natural  gas
properties and the value of our undeveloped acreage could decline in the future.

Conservation measures and technological advances could reduce demand for oil and natural gas.

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. 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  marketability  of  our  production  is  dependent  upon  transportation  and  other  facilities,  certain  of  which  we  do  not  control.  If  these  facilities  are
unavailable, our operations could be interrupted and our revenues reduced.

The  marketability  of  our  oil  and  natural  gas  production  depends  in  part  upon  the  availability,  proximity  and  capacity  of  transportation  facilities
owned by third parties. Our oil production is transported from the wellhead to our tank batteries by our gathering system, which interconnects with third party
pipelines. Our natural gas production is generally transported by our gathering lines from the wellhead to an interconnection point with the purchaser. We do
not  control  third  party  transportation  facilities  and  our  access  to  them  may  be  limited  or  denied.  Insufficient  production  from  our  wells  to  support  the
construction  of  pipeline  facilities  by  our  purchasers  or  a  significant  disruption  in  the  availability  of  our  or  third  party  transportation  facilities  or  other
production facilities could adversely impact our ability to deliver to market or produce our oil and natural gas and thereby cause a significant interruption in
our operations. For example, on certain occasions we have experienced high line pressure at our tank batteries with occasional flaring due to the inability of
the gas gathering systems in the areas in which we operate to support the increased production of natural gas in the Permian Basin. If, in the future, we are
unable,  for  any  sustained  period,  to  implement  acceptable  delivery  or  transportation  arrangements  or  encounter  production  related  difficulties,  we  may  be
required to shut in or curtail production. In addition, the amount of oil and natural gas that can be produced and sold may be subject to curtailment in certain
other circumstances outside of our control, such as pipeline interruptions due to maintenance, excessive pressure, ability of downstream processing facilities
to accept unprocessed gas, physical damage to the gathering or transportation system or lack of contracted capacity on such systems. The curtailments arising
from these and similar circumstances may last from a few days to several months, and in many cases, we are provided with limited, if any, notice as to when
these circumstances will arise and their duration. Any such shut in or curtailment, or an inability to obtain favorable terms for delivery of the oil and natural
gas produced from our fields, would adversely affect our financial condition and results of operations.

Our operations are subject to various governmental laws and regulations which require compliance that can be burdensome and expensive.

Our oil and natural gas operations are subject to various federal, state and local governmental regulations that may be changed from time to time in
response  to  economic  and  political  conditions.  Matters  subject  to  regulation  include  discharge  permits  for  drilling  operations,  drilling  bonds,  reports
concerning operations, the spacing of wells, unitization and pooling of properties and taxation. From time to time, regulatory agencies have imposed price
controls and limitations on production by restricting the rate of flow of oil and natural gas wells below actual production capacity to conserve supplies of oil
and gas. In addition, the production, handling, storage, transportation, remediation, emission and disposal of oil and natural gas, by-products thereof and other
substances and materials produced or used in connection with oil and natural gas operations are subject to regulation under federal, state and local laws and
regulations  primarily  relating  to  protection  of  human  health  and  the  environment.  Failure  to  comply  with  these  laws  and  regulations  may  result  in  the
assessment  of  sanctions,  including  administrative,  civil  or  criminal  penalties,  permit  revocations,  requirements  for  additional  pollution  controls  and
injunctions limiting or prohibiting some or all of our operations. Moreover, these laws and regulations imposed strict requirements for water and air pollution
control and solid waste management. Significant expenditures may be required to comply with governmental laws and regulations applicable to us. Even if
federal regulatory burdens temporarily ease, the historic trend of more expansive and stricter environmental legislation and regulations may continue in the
long-term, and at the state and local levels. See Item 1. “Business—Regulation” for a description of certain laws and regulations that affect us.

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

Hydraulic fracturing is an important common practice that is used to stimulate production of hydrocarbons 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, legislation has been proposed in recent sessions of Congress to amend
the Safe Drinking Water Act to repeal the exemption for hydraulic fracturing from the definition of “underground injection,” to require federal permitting and
regulatory  control  of  hydraulic  fracturing,  and  to  require  disclosure  of  the  chemical  constituents  of  the  fluids  used  in  the  fracturing  process.  Furthermore,
several federal agencies have asserted regulatory authority over certain aspects of the process. For example, the EPA has taken the position that hydraulic
fracturing with fluids containing diesel fuel is subject to regulation under the Underground Injection Control program, specifically as “Class II” Underground
Injection Control wells under the Safe Drinking Water Act.

On June 28, 2016, the EPA published a final rule prohibiting the discharge of wastewater from onshore unconventional oil and natural gas extraction
facilities  to  publicly  owned  wastewater  treatment  plants.  The  EPA  is  also  conducting  a  study  of  private  wastewater  treatment  facilities  (also  known  as
centralized waste treatment, or CWT, facilities) accepting oil and natural gas extraction wastewater. The EPA is collecting data and information related to the
extent  to  which  CWT  facilities  accept  such  wastewater,  available  treatment  technologies  (and  their  associated  costs),  discharge  characteristics,  financial
characteristics of CWT facilities, and the environmental impacts of discharges from CWT facilities.

On August 16, 2012, the EPA published final regulations under the federal Clean Air Act that establish new air emission controls for oil and natural
gas production and natural gas processing operations. Specifically, the EPA’s rule package includes New Source Performance standards to address emissions
of sulfur dioxide and volatile organic compounds and a separate set of emission standards to address hazardous air pollutants frequently associated with oil
and natural gas production and processing activities. The final rules seek to achieve a 95% reduction in volatile organic compounds emitted by requiring the
use of reduced emission completions or “green completions” on all hydraulically-fractured wells constructed or refractured after January 1, 2015. The EPA
received numerous requests for reconsideration of these rules from both industry and the environmental community, and court challenges to the rules were
also filed. In response, the EPA has issued, and will likely continue to issue, revised rules responsive to some of the requests for reconsideration. For a more
detailed  discussion  of  federal  laws  concerning  hydraulic  fracturing,  see  “Items  1  and  2.  Business  and  Properties—Regulation—Regulation  of  Hydraulic
Fracturing.”

Furthermore, there are certain governmental reviews either underway or being proposed that focus on environmental aspects of hydraulic fracturing
practices. On December 13, 2016, the EPA released a study examining the potential for hydraulic fracturing activities to impact drinking water resources,
finding that, under some circumstances, the use of water in hydraulic fracturing activities can impact drinking water resources. Also, on February 6, 2015, the
EPA  released  a  report  with  findings  and  recommendations  related  to  public  concern  about  induced  seismic  activity  from  disposal  wells.  The  report
recommends strategies for managing and minimizing the potential for significant injection-induced seismic events. Other governmental agencies, including
the U.S. Department of Energy, the U.S. Geological Survey, and the U.S. Government Accountability Office, have evaluated or are evaluating various other
aspects of hydraulic fracturing. These ongoing or proposed studies could spur initiatives to further regulate hydraulic fracturing, and could ultimately make it
more difficult or costly for us to perform fracturing and increase our costs of compliance and doing business.

Several states, including Texas, and local jurisdictions, 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.
For  a  more  detailed  discussion  of  state  and  local  laws  and  initiatives  concerning  hydraulic  fracturing,  see  “Items  1  and  2.  Business  and  Properties—
Regulation—Regulation of Hydraulic Fracturing.” We use hydraulic fracturing extensively in connection with the development and production of certain of
our oil and natural gas properties and any increased federal, state, local, foreign or international regulation of hydraulic fracturing could reduce the volumes of
oil and natural gas that we can economically recover, which could materially and adversely affect our revenues and results of operations.

There  has  been  increasing  public  controversy  regarding  hydraulic  fracturing  with  regard  to  the  use  of  fracturing  fluids,  induced  seismic  activity,
impacts on drinking water supplies, use of water and the potential for impacts to surface water, groundwater and the environment generally. A number of
lawsuits and enforcement actions have been initiated across the country implicating hydraulic fracturing practices. If new laws or regulations that significantly
restrict  hydraulic  fracturing  are  adopted,  such  laws  could  make  it  more  difficult  or  costly  for  us  to  perform  fracturing  to  stimulate  production  from  tight
formations as well as make it easier for third parties opposing the hydraulic fracturing process to initiate legal proceedings based on allegations that specific
chemicals used in the fracturing process could adversely affect groundwater. In addition, if hydraulic fracturing is further

37

Table of Contents

regulated at the federal, state or local level, our fracturing activities could become subject to additional permitting and financial assurance requirements, more
stringent  construction  specifications,  increased  monitoring,  reporting  and  recordkeeping  obligations,  plugging  and  abandonment  requirements  and  also  to
attendant  permitting  delays  and  potential  increases  in  costs.  Such  changes  could  cause  us  to  incur  substantial  compliance  costs,  and  compliance  or  the
consequences of any failure to comply by us could have a material adverse effect on our financial condition and results of operations. At this time, it is not
possible to estimate the impact on our business of newly enacted or potential federal, state or local laws governing hydraulic fracturing.

Our operations may be exposed to significant delays, costs and liabilities as a result of environmental, health and safety requirements applicable to our
business activities.

We may incur significant delays, costs and liabilities as a result of federal, state and local environmental, health and safety requirements applicable to
our exploration, development and production activities. These laws and regulations may, among other things: (i) require us to obtain a variety of permits or
other  authorizations  governing  our  air  emissions,  water  discharges,  waste  disposal  or  other  environmental  impacts  associated  with  drilling,  producing  and
other  operations;  (ii)  regulate  the  sourcing  and  disposal  of  water  used  in  the  drilling,  fracturing  and  completion  processes;  (iii)  limit  or  prohibit  drilling
activities in certain areas and on certain lands lying within wilderness, wetlands, ecologically or seismically sensitive areas; (iv) require remedial action to
prevent or mitigate pollution from former operations such as plugging abandoned wells or closing earthen pits; and/or (v) impose substantial liabilities for
spills, pollution or failure to comply with regulatory filings. In addition, these laws and regulations may restrict the rate of oil or natural gas production. These
laws  and  regulations  are  complex,  change  frequently  and  have  tended  to  become  increasingly  stringent  over  time.  Failure  to  comply  with  these  laws  and
regulations  may  result  in  the  assessment  of  administrative,  civil  and  criminal  penalties,  imposition  of  cleanup  and  site  restoration  costs  and  liens,  the
suspension  or  revocation  of  necessary  permits,  licenses  and  authorizations,  the  requirement  that  additional  pollution  controls  be  installed  and,  in  some
instances, issuance of orders or injunctions limiting or requiring discontinuation of certain operations. Under certain environmental laws that impose strict as
well as joint and several liability, we may be required to remediate contaminated properties currently or formerly operated by us or facilities of third parties
that received waste generated by our operations regardless of whether such contamination resulted from the conduct of others or from consequences of our
own actions that were in compliance with all applicable laws at the time those actions were taken. In addition, claims for damages to persons or property,
including  natural  resources,  may  result  from  the  environmental,  health  and  safety  impacts  of  our  operations.  In  addition,  the  risk  of  accidental  and/or
unpermitted spills or releases from our operations could expose us to significant liabilities, penalties and other sanctions under applicable laws. To the extent
laws  are  enacted  or  other  governmental  action  is  taken  that  restricts  drilling  or  imposes  more  stringent  and  costly  operating,  waste  handling,  disposal  and
cleanup requirements, our business, prospects, financial condition or results of operations could be materially adversely affected.

Restrictions on drilling activities intended to protect certain species of wildlife may adversely affect our ability to conduct drilling activities in some of the
areas where we operate.

Oil and natural gas operations in our operating areas can be adversely affected by seasonal or permanent restrictions on drilling activities designed to
protect  various  wildlife.  Seasonal  restrictions  may  limit  our  ability  to  operate  in  protected  areas  and  can  intensify  competition  for  drilling  rigs,  oilfield
equipment,  services,  supplies  and  qualified  personnel,  which  may  lead  to  periodic  shortages  when  drilling  is  allowed.  These  constraints  and  the  resulting
shortages  or  high  costs  could  delay  our  operations  and  materially  increase  our  operating  and  capital  costs.  Permanent  restrictions  imposed  to  protect
threatened or endangered species could prohibit drilling in certain areas or require the implementation of expensive mitigation measures. The designation of
previously unprotected species in areas where we operate as threatened or endangered could cause us to incur increased costs arising from species protection
measures or could result in limitations on our exploration and production activities that could have an adverse impact on our ability to develop and produce
our reserves.

Derivatives reform legislation and related regulations could have an adverse effect on our ability to hedge risks associated with our business.

The July 2010 Dodd-Frank Wall Street Reform and Consumer Protection Act, which we refer to as Dodd-Frank Act, provides for federal oversight
of the over-the-counter derivatives market and entities that participate in that market and mandates that the Commodity Futures Trading Commission, which
we refer to as the CFTC, the SEC, and federal regulators of financial institutions, which we refer to as the Prudential Regulators, adopt rules or regulations
implementing the Dodd-Frank Act and providing definitions of terms used in the Dodd-Frank Act. The Dodd-Frank Act establishes margin requirements and
requires clearing and trade execution practices for certain market participants and may result in certain market participants needing to curtail or cease their
derivatives activities.

Although some of the rules necessary to implement the Dodd-Frank Act remain to be adopted, the CFTC, the SEC and the Prudential Regulators

have issued many rules to implement the Dodd-Frank Act, including a rule, which we refer to as the

38

Table of Contents

Mandatory Clearing Rule, requiring clearing of hedges, or swaps, that are subject to it (currently, only certain interest rate and credit default swaps, which we
do not presently have), a rule, which we refer to as the End User Exception, establishing an “end user” exception to the Mandatory Clearing Rule, a rule,
which we refer to as the Margin Rule, setting forth collateral requirements in connection with swaps that are not cleared and also an exception to the Margin
Rule for end users that are not financial end users, which exception we refer to as the Non-Financial End User Exception, and a rule, subsequently vacated by
the United States District Court for the District of Columbia and remanded to the CFTC for further proceedings, imposing position limits. The CFTC has
three times proposed a new version of this rule, with respect to which the comment period closed but the rule was not adopted, and another version of this
rule, which we refer to as the Latest-Proposed Position Limit Rule, with respect to which the comment period will close on April 29, 2020 unless extended
and a final rule may or may not be issued. The Latest-Proposed Position Limit Rule provides an exemption from the position limits for swaps that constitute
“bona fide hedging positions” within the definition of such term under the Latest-Proposed Position Limit Rule, subject to the party claiming the exemption
complying with the applicable filing, recordkeeping and reporting requirements of the Latest-Proposed Position Limit Rule.

We qualify for the End User Exception and will utilize it if the Mandatory Clearing Rule is expanded to cover swaps in which we participate, we
qualify for the Non-Financial End User Exception and will not be required to post margin in connection with uncleared swaps under the Margin Rule, and our
existing and anticipated hedging positions constitute “bona fide hedging positions” under the Re-Proposed Position Limit Rule and we intend to undertake the
filing, recordkeeping and reporting necessary to utilize the bona fide hedging position exemption under the Latest-Proposed Position Limit Rule if and when
it becomes effective, so we do not expect to be directly affected by any of such rules. However, most if not all of our hedge counterparties will be subject to
mandatory clearing in connection with their hedging activities with parties who do not qualify for the End User Exception and will be required to post margin
in connection with their hedging activities with other swap dealers, major swap participants, financial end users and other persons that do not qualify for the
Non-Financial End User Exception. In addition, the European Union and other non-U.S. jurisdictions have enacted laws and regulations (including laws and
regulations giving the European Union financial authorities the power to write down amounts we may be owed on hedging agreements with counterparties
subject  to  such  laws  and  regulations  and/or  require  that  we  accept  equity  interests  in  such  counterparties  in  lieu  of  cash  in  satisfaction  of  such  amounts),
which we refer to collectively as Foreign Regulations, which may apply to our transactions with counterparties subject to such Foreign Regulations, which we
refer to as Foreign Counterparties, and the U.S. adopted law and rules, which we call the U.S. Resolution Stay Rules, clarifying similar rights of U.S. banking
authorities with respect to banking institutions subject to their regulation. The Dodd-Frank Act, the rules which have been adopted and not vacated, and, to
the extent that the Latest-Proposed Position Limit Rule is effected, such proposed rule and the U.S. Resolution Stay Rules could significantly increase the cost
of our derivative contracts, materially alter the terms of our derivative contracts, reduce the availability of derivatives to us that we have historically used to
protect  against  risks  that  we  encounter  in  our  business,  reduce  our  ability  to  monetize  or  restructure  our  existing  derivative  contracts  and  increase  our
exposure to less creditworthy counterparties. The Foreign Regulations could have similar effects. If we reduce our use of derivatives as a result of the Dodd-
Frank Act and regulation, the U.S. Resolution Stay Rules and Foreign Regulations, our results of operations may become more volatile and our cash flows
may be less predictable, which could adversely affect our ability to plan for and fund capital expenditures. Finally, the Dodd-Frank Act was intended, in part,
to reduce the volatility of oil and natural gas prices, which some legislators attributed to speculative trading in derivatives and commodity contracts related to
oil and natural gas. Our revenues could therefore be adversely affected if a consequence of the Dodd-Frank Act and regulations is to lower commodity prices.
Any of these consequences could have a material adverse effect on us, our financial condition and our results of operations.

Recently enacted U.S. tax legislation as well as future U.S. tax legislations may adversely affect our business, results of operations, financial condition
and cash flow.

On December 22, 2017, the President signed into law Public Law No. 115-97, a comprehensive tax reform bill commonly referred to as the Tax Cuts
and Jobs Act, which we refer to as the Tax Act, that significantly reforms the Internal Revenue Code of 1986, as amended, which we refer to as the Code.
Among other changes, the Tax Act (i) reduces the maximum U.S. corporate income tax rate from 35% to 21%, (ii) preserves long-standing upstream oil and
gas  tax  provisions  such  as  immediate  deduction  of  intangible  drilling,  (iii)  allows  for  immediate  expensing  of  capital  expenditures  for  tangible  personal
property for a period of time, (iv) modifies the provisions related to the limitations on deductions for executive compensation of publicly traded corporations
and (v) enacts new limitations regarding the deductibility of interest expense. The Tax Act is complex and far-reaching, and while we have evaluated the
resulting impact of its enactment on us and recorded adjustments as required in our financial statements, aspects of the Tax Act are unclear and may not be
clarified for some time. The ultimate impact of the Tax Act may differ from our estimates due to changes in interpretations and assumptions made by us as
well as additional regulatory guidance that may be issued, and any such changes in our interpretations and assumptions could have an adverse effect on our
business, results of operations, financial condition and cash flow.

In  addition,  from  time  to  time,  legislation  has  been  proposed  that,  if  enacted  into  law,  would  make  significant  changes  to  U.S.  federal  and  state

income tax laws affecting the oil and gas industry, including (i) eliminating the immediate deduction for

39

 
Table of Contents

intangible drilling and development costs, (ii) the repeal of the percentage depletion allowance for oil and natural gas properties; and (iii) an extension of the
amortization period for certain geological and geophysical expenditures. While these specific changes are not included in the Tax Act, no accurate prediction
can be made as to whether any such legislative changes will be proposed or enacted in the future or, if enacted, what the specific provisions or the effective
date of any such legislation would be. These proposed changes in the U.S. tax law, if adopted, or other similar changes that would impose additional tax on
our activities or reduce or eliminate deductions currently available with respect to natural gas and oil exploration, development or similar activities, could
adversely affect our business, results of operations, financial condition and cash flows.

Regulation of greenhouse gas emissions could result in increased operating costs and reduced demand for the oil and natural gas we produce.

In recent years, federal, state and local governments have taken steps to reduce emissions of greenhouse gases. The EPA has finalized a series of
greenhouse  gas  monitoring,  reporting  and  emissions  control  rules  for  the  oil  and  natural  gas  industry,  and  the  U.S.  Congress  has,  from  time  to  time,
considered  adopting  legislation  to  reduce  emissions.  Almost  one-half  of  the  states  have  already  taken  measures  to  reduce  emissions  of  greenhouse  gases
primarily through the development of greenhouse gas emission inventories and/or regional greenhouse gas cap-and-trade programs. While we are subject to
certain federal greenhouse gas monitoring and reporting requirements, our operations currently are not adversely impacted by existing federal, state and local
climate change initiatives. For a description of existing and proposed greenhouse gas rules and regulations, see “Items 1 and 2. Business and Properties—
Regulation—Environmental Regulation—Climate Change.”

At the international level, in December 2015, the United States participated in 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  Agreement  went  into  effect  on  November  4,  2016.  The
Agreement establishes a framework for the parties to cooperate and report actions to reduce greenhouse gas emissions. However, on June 1, 2017, President
Trump announced that the United States would withdraw from the Paris Agreement, and begin negotiations to either re-enter or negotiate an entirely new
agreement with more favorable terms for the United States. The Paris Agreement sets forth a specific exit process, whereby a party may not provide notice of
its  withdrawal  until  three  years  from  the  effective  date,  with  such  withdrawal  taking  effect  one  year  from  such  notice.  On  November  4,  2019,  the  Trump
Administration  submitted  its  formal  notification  of  withdrawal  to  the  United  Nations.  It  is  not  clear  what  steps,  if  any,  will  be  taken  to  negotiate  a  new
agreement, or what terms would be included in such an agreement. In response to the announcement, many state and local leaders have stated their intent to
intensify efforts to uphold the commitments set forth in the international accord.

Restrictions  on  emissions  of  methane  or  carbon  dioxide  that  may  be  imposed  could  adversely  impact  the  demand  for,  price  of,  and  value  of  our
products and reserves. As our operations also emit greenhouse gases directly, current and future laws or regulations limiting such emissions could increase
our  own  costs.  At  this  time,  it  is  not  possible  to  accurately  estimate  how  potential  future  laws  or  regulations  addressing  greenhouse  gas  emissions  would
impact our business.

In addition, there have also been efforts in recent years to influence the investment community, including investment advisors and certain sovereign
wealth,  pension  and  endowment  funds  promoting  divestment  of  fossil  fuel  equities  and  pressuring  lenders  to  limit  funding  to  companies  engaged  in  the
extraction of fossil fuel reserves. Such environmental activism and initiatives aimed at limiting climate change and reducing air pollution could interfere with
our  business  activities,  operations  and  ability  to  access  capital.  Furthermore,  claims  have  been  made  against  certain  energy  companies  alleging  that
greenhouse  gas  emissions  from  oil  and  natural  gas  operations  constitute  a  public  nuisance  under  federal  and/or  state  common  law.  As  a  result,  private
individuals or public entities may seek to enforce environmental laws and regulations against us and could allege personal injury, property damages or other
liabilities. While our business is not a party to any such litigation, we could be named in actions making similar allegations. An unfavorable ruling in any
such case could significantly impact our operations and could have an adverse impact on our financial condition.

Moreover, there has been public discussion that climate change may be associated with extreme weather conditions such as more intense hurricanes,
thunderstorms,  tornadoes  and  snow  or  ice  storms,  as  well  as  rising  sea  levels.  Another  possible  consequence  of  climate  change  is  increased  volatility  in
seasonal temperatures. Some studies indicate that climate change could cause some areas to experience temperatures substantially hotter or colder than their
historical averages. Extreme weather conditions can interfere with our production and increase our costs and damage resulting from extreme weather may not
be  fully  insured.  However,  at  this  time,  we  are  unable  to  determine  the  extent  to  which  climate  change  may  lead  to  increased  storm  or  weather  hazards
affecting our operations.

Legislation  or  regulatory  initiatives  intended  to  address  seismic  activity  could  restrict  our  drilling  and  production  activities,  as  well  as  our  ability  to
dispose of produced water gathered from such activities, which could have a material adverse effect on our business.

State and federal regulatory agencies have recently focused on a possible connection between hydraulic fracturing related activities, particularly the
underground injection of wastewater into disposal wells, and the increased occurrence of seismic activity, and regulatory agencies at all levels are continuing
to  study  the  possible  linkage  between  oil  and  gas  activity  and  induced  seismicity.  In  addition,  a  number  of  lawsuits  have  been  filed  in  some  states,  most
recently  in  Oklahoma,  alleging  that  disposal  well  operations  have  caused  damage  to  neighboring  properties  or  otherwise  violated  state  and  federal  rules
regulating  waste  disposal.  In  response  to  these  concerns,  regulators  in  some  states  are  seeking  to  impose  additional  requirements,  including  requirements
regarding the permitting of produced water disposal wells or otherwise to assess the relationship between seismicity and the use of such wells. For example,
on October 28, 2014, the Texas Railroad Commission adopted disposal well rule amendments designed, among other things, to require applicants for new
disposal wells that will receive non-hazardous produced water or other oil and gas waste to conduct seismic activity searches utilizing the U.S. Geological
Survey. The searches are intended to determine the potential for earthquakes within a circular area of 100 square miles around a proposed new disposal well.
If the permittee or an applicant of a disposal well permit fails to demonstrate that the produced water or other fluids are confined to the disposal zone or if
scientific data indicates such a disposal well is likely to be or determined to be contributing to seismic activity, then the agency may deny, modify, suspend or
terminate the permit application or existing operating permit for that well. The Commission has used this authority to deny permits for waste disposal wells.

We dispose of large volumes of produced water gathered from our drilling and production operations by injecting it into wells pursuant to permits
issued to us by governmental authorities overseeing such disposal activities. While these permits are issued pursuant to existing laws and regulations, these
legal  requirements  are  subject  to  change,  which  could  result  in  the  imposition  of  more  stringent  operating  constraints  or  new  monitoring  and  reporting
requirements, owing to, among other things, concerns of the public or governmental authorities regarding such gathering or disposal activities. The adoption
and implementation of any new laws or regulations that restrict our ability to use hydraulic fracturing or dispose of produced water gathered from our drilling
and production activities by owned disposal wells, could have a material adverse effect on our business, financial condition and results of operations.

A change in the jurisdictional characterization of some of our assets by federal, state or local regulatory agencies or a change in policy by those agencies
may result in increased regulation of our assets, which may cause our revenues to decline and operating expenses to increase.

Although FERC has not made a formal determination with respect to the facilities we consider to be natural gas gathering pipelines, we believe that
our subsidiary Rattler LLC’s natural gas gathering pipelines meet the traditional tests that FERC has used to determine that pipelines perform primarily a
gathering  function  and  are,  therefore,  not  subject  to  FERC  jurisdiction.  The  distinction  between  FERC-regulated  interstate  transportation  services  and
federally  unregulated  gathering  services,  however,  has  been  the  subject  of  substantial  litigation,  and  FERC  determines  whether  facilities  are  gathering
facilities on a case-by-case basis, so the classification and regulation of our gathering facilities is subject to change based on future determinations by FERC,
the courts or Congress. If FERC were to consider the status of an individual facility and determine that the facility or services provided by it are not exempt
from  FERC  regulation  under  the  NGA,  and  that  the  facility  provides  interstate  transportation  service,  the  rates  for,  and  terms  and  conditions  of,  services
provided by such facility would be subject to regulation by FERC under the NGA or the Natural Gas Policy Act, or NGPA. Such regulation could decrease
revenue, increase operating costs, and, depending upon the facility in question, adversely affect our results of operations and cash flow. In addition, if any of
Rattler LLC’s facilities were found to have provided services or otherwise operated in violation of the NGA or NGPA, this could result in the imposition of
substantial civil penalties, as well as a requirement to disgorge revenues collected for such services in excess of the maximum rates established by FERC.

Even though we consider Rattler LLC’s natural gas gathering pipelines to be exempt from the jurisdiction of FERC under the NGA, FERC regulation
of interstate natural gas transportation pipelines may indirectly impact gathering services. FERC’s policies and practices across the range of its natural gas
regulatory activities, including, for example, its policies on interstate open access transportation, ratemaking, capacity release, and market center promotion
may  indirectly  affect  intrastate  markets  and  gathering  services.  In  recent  years,  FERC  has  pursued  pro-competitive  policies  in  its  regulation  of  interstate
natural gas pipelines. However, we cannot assure you that the FERC will continue to pursue this approach as it considers matters such as pipeline rates and
rules and policies that may indirectly affect the natural gas gathering services.

Natural gas gathering may receive greater regulatory scrutiny at the state level; therefore, our natural gas gathering operations could be adversely
affected should they become subject to the application of state regulation of rates and services. Rattler LLC’s gathering operations could also be subject to
safety and operational regulations relating to the design, construction,

41

Table of Contents

testing,  operation,  replacement  and  maintenance  of  gathering  facilities.  We  cannot  predict  what  effect,  if  any,  such  changes  might  have  on  our  or  Rattler
LLC’s  operations,  but  we  could  be  required  to  incur  additional  capital  expenditures  and  increased  operating  costs  depending  on  future  legislative  and
regulatory changes.

Federal and state legislative and regulatory initiatives relating to pipeline safety that require the use of new or more stringent safety controls or result in
more stringent enforcement of applicable legal requirements could subject us to increased capital costs, operational delays and costs of operation.

The  U.S.  Department  of  Transportation,  or  DOT,  through  the  PHMSA  and  state  agencies,  enforces  safety  regulations  with  respect  to  the  design,
construction, operation, maintenance, inspection and management of certain of Rattler LLC’s pipeline facilities. The PHMSA requires pipeline operators to
implement integrity management programs, including more frequent inspections and other measures to ensure pipeline safety in high-consequence areas, or
HCAs, defined as those areas that are unusually sensitive to environmental damage, that cross a navigable waterway, or that have a high population density.
The  regulations  require  operators  to  (i)  perform  ongoing  assessments  of  pipeline  integrity,  (ii)  identify  and  characterize  applicable  threats  to  pipeline
segments that could impact a HCA, (iii) improve data collection, integration and analysis, (iv) repair and remediate pipelines as necessary and (v) implement
preventive  and  mitigating  actions.  These  regulations  contain  requirements  for  the  development  and  implementation  of  pipeline  integrity  management
programs,  which  include  the  inspection  and  testing  of  pipelines  and  the  correction  of  anomalies.  The  PHMSA’s  regulations  also  require  that  pipeline
operation and maintenance personnel meet certain qualifications and that pipeline operators develop comprehensive spill response plans, including extensive
spill response training for pipeline personnel.

The Pipeline Safety, Regulatory Certainty, and Job Creation Act of 2011, also known as the Pipeline Safety and Job Creation Act, and the PIPES
Act, are the most recent enactments of federal legislation to amend the NGPSA and the HLPSA which are pipeline safety laws requiring increased safety
measures  for  natural  gas  and  hazardous  liquids  pipelines.  Among  other  things,  the  Pipeline  Safety  and  Job  Creation  Act  directs  the  Secretary  of
Transportation  to  promulgate  regulations  relating  to  expanded  integrity  management  requirements,  automatic  or  remote-controlled  valve  use,  excess  flow
valve use, leak detection system installation, material strength testing and verification of the maximum allowable pressure of certain pipelines. The Pipeline
Safety and Job Creation Act also increases the maximum penalty for violation of pipeline safety regulations from $100,000 to $200,000 per violation per day
of violation and from $1.0 million to $2.0 million for a related series of violations. Effective July 31, 2019, to account for inflation, those maximum civil
penalties were increased to $218,647 per violation per day, with a maximum of $2,186,465 for a related series of violations. The PIPES Act ensures that the
PHMSA completes the Pipeline Safety and Job Creation Act requirements; reforms PHMSA to be a more dynamic, data-driven regulator; and closes gaps in
federal standards.

On October 1, 2019, PHMSA published final rules to expand its integrity management requirements and impose new pressure testing requirements
on regulated pipelines, including certain segments outside High Consequence Areas. The rules, once effective, also extend reporting requirements to certain
previously unregulated gathering lines. The safety enhancement requirements and other provisions of the Pipeline Safety and Job Creation Act and the PIPES
Act, as well as any implementation of PHMSA rules thereunder and/or related rule making proceedings, could require us to install new or modified safety
controls,  pursue  additional  capital  projects  or  conduct  maintenance  programs  on  an  accelerated  basis,  any  or  all  of  which  tasks  could  result  in  increased
operating costs that could have a material adverse effect on our or Rattler LLC’s results of operations or financial position.

If third party pipelines or other facilities interconnected to Rattler LLC’s midstream systems become partially or fully unavailable, or if the volumes we
gather or treat do not meet the quality requirements of such pipelines or facilities, our midstream operations could be adversely affected.

Our subsidiary Rattler LLC’s midstream systems are connected to other pipelines or facilities, the majority of which are owned by third parties. The
continuing operation of such third party pipelines or facilities is not within our control. If any of these pipelines or facilities becomes unable to transport, treat
or process natural gas or crude oil, or if the volumes we gather or transport do not meet the quality requirements of such pipelines or facilities, our midstream
operations could be adversely affected.

Rattler LLC’s rates are subject to review by federal regulators, which could adversely affect our revenues.

Our subsidiary Rattler LLC has a tariff on file with FERC to gather crude oil in interstate commerce. Pipelines that gather or transport crude oil for
third parties in interstate commerce are, among other things, subject to regulation of the rates and terms and conditions of service by the FERC. Rattler is also
subject to annual reporting requirements and may also be required to respond to requests for information from government agencies, including compliance
audits conducted by FERC.

We operate in areas of high industry activity, which may affect our ability to hire, train or retain qualified personnel needed to manage and operate our
assets.

Our operations and drilling activity are concentrated in the Permian Basin in West Texas, an area in which industry activity has increased rapidly. As
a result, demand for qualified personnel in this area, and the cost to attract and retain such personnel, has increased over the past few years due to competition
and  may  increase  substantially  in  the  future.  Moreover,  our  competitors  may  be  able  to  offer  better  compensation  packages  to  attract  and  retain  qualified
personnel than we are able to offer.

Any delay or inability to secure the personnel necessary for us to continue or complete our current and planned development activities could lead to
a reduction in production volumes.  Any such negative effect on production volumes, or significant increases in costs, could have a material adverse effect on
our business, financial condition and results of operations.

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, including our Chief Executive Officer, Travis D. Stice,
could disrupt our operations. We have employment agreements with these executives which contain restrictions on competition with us in the event they cease
to  be  employed  by  us.  However,  as  a  practical  matter,  such  employment  agreements  may  not  assure  the  retention  of  our  employees.  Further,  we  do  not
maintain “key person” life 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.

Drilling for and producing oil and natural gas are high-risk activities with many uncertainties that may result in a total loss of investment and adversely
affect our business, financial condition or results of operations.

Our drilling activities are subject to many risks. For example, we cannot assure you that new wells drilled by us will be productive or that we will
recover all or any portion of our investment in such wells. Drilling for oil and natural gas often involves unprofitable efforts, not only from dry wells but also
from wells that are productive but do not produce sufficient oil or natural gas to return a profit at then realized prices after deducting drilling, operating and
other costs. The seismic data and other technologies we use do not allow us to know conclusively prior to drilling a well that oil or natural gas is present or
that  it  can  be  produced  economically.  The  costs  of  exploration,  exploitation  and  development  activities  are  subject  to  numerous  uncertainties  beyond  our
control, and increases in those costs can adversely affect the economics of a project. Further, our drilling and producing operations may be curtailed, delayed,
canceled or otherwise negatively impacted as a result of other factors, including:

•

•

•

•

•

•

•

•

unusual or unexpected geological formations;

loss of drilling fluid circulation;

title problems;

facility or equipment malfunctions;

unexpected operational events;

shortages or delivery delays of equipment and services;

compliance with environmental and other governmental requirements; and

adverse weather conditions.

Any of these risks can cause substantial losses, including personal injury or loss of life, damage to or destruction of property, natural resources and

equipment, pollution, environmental contamination or loss of wells and other regulatory penalties.

Our development and exploratory drilling efforts and our well operations may not be profitable or achieve our targeted returns.

Historically,  we  have  acquired  significant  amounts  of  unproved  property  in  order  to  further  our  development  efforts  and  expect  to  continue  to
undertake  acquisitions  in  the  future.  Development  and  exploratory  drilling  and  production  activities  are  subject  to  many  risks,  including  the  risk  that  no
commercially  productive  reservoirs  will  be  discovered.  We  acquire  unproved  properties  and  lease  undeveloped  acreage  that  we  believe  will  enhance  our
growth potential and increase our earnings over time.

43

Table of Contents

However, we cannot assure you that all prospects will be economically viable or that we will not abandon our investments. Additionally, we cannot assure
you that unproved property acquired by us or undeveloped acreage leased by us will be profitably developed, that new wells drilled by us in prospects that we
pursue will be productive or that we will recover all or any portion of our investment in such unproved property or wells.

Drilling for oil and natural gas may involve unprofitable efforts, not only from dry wells but also from wells that are productive but do not produce
sufficient commercial quantities to cover the drilling, operating and other costs. The cost of drilling, completing and operating a well is often uncertain, and
many factors can adversely affect the economics of a well or property. Drilling operations may be curtailed, delayed or canceled as a result of unexpected
drilling conditions, equipment failures or accidents, shortages of equipment or personnel, environmental issues and for other reasons. In addition, wells that
are  profitable  may  not  meet  our  internal  return  targets,  which  are  dependent  upon  the  current  and  expected  future  market  prices  for  oil  and  natural  gas,
expected costs associated with producing oil and natural gas and our ability to add reserves at an acceptable cost.

Operating hazards and uninsured risks may result in substantial losses and could prevent us from realizing profits.

Our operations are subject to all of the hazards and operating risks associated with drilling for and production of oil and natural gas, including the
risk  of  fire,  explosions,  blowouts,  surface  cratering,  uncontrollable  flows  of  natural  gas,  oil  and  formation  water,  pipe  or  pipeline  failures,  abnormally
pressured  formations,  casing  collapses  and  environmental  hazards  such  as  oil  spills,  gas  leaks  and  ruptures  or  discharges  of  toxic  gases.  In  addition,  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. 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, suspension of operations and repairs required to resume operations.

We endeavor to contractually allocate potential liabilities and risks between us and the parties that provide us with services and goods, which include
pressure  pumping  and  hydraulic  fracturing,  drilling  and  cementing  services  and  tubular  goods  for  surface,  intermediate  and  production  casing.  Under  our
agreements  with  our  vendors,  to  the  extent  responsibility  for  environmental  liability  is  allocated  between  the  parties,  (i)  our  vendors  generally  assume  all
responsibility  for  control  and  removal  of  pollution  or  contamination  which  originates  above  the  surface  of  the  land  and  is  directly  associated  with  such
vendors’  equipment  while  in  their  control  and  (ii)  we  generally  assume  the  responsibility  for  control  and  removal  of  all  other  pollution  or  contamination
which may occur during our operations, including pre-existing pollution and pollution which may result from fire, blowout, cratering, seepage or any other
uncontrolled  flow  of  oil,  gas  or  other  substances,  as  well  as  the  use  or  disposition  of  all  drilling  fluids.  In  addition,  we  generally  agree  to  indemnify  our
vendors for loss or destruction of vendor-owned property that occurs in the well hole (except for damage that occurs when a vendor is performing work on a
footage, rather than day work, basis) or as a result of the use of equipment, certain corrosive fluids, additives, chemicals or proppants. 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  contractual  arrangements  with  terms  that  vary  from  the  above  allocations  of  risk.  As  a  result,  we  may  incur
substantial losses which could materially and adversely affect our financial condition and results of operations.

In accordance with what we believe to be customary industry practice, we historically have maintained insurance against some, but not all, of our
business risks. Our insurance may not be adequate to cover any losses or liabilities we may suffer. Also, insurance may no longer be available to us or, if it is,
its availability may be at premium levels that do not justify its purchase. The occurrence of a significant uninsured claim, a claim in excess of the insurance
coverage limits maintained by us or a claim at a time when we are not able to obtain liability insurance could have a material adverse effect on our ability to
conduct normal business operations and on our financial condition, results of operations or cash flow. 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. We may also be liable for environmental damage caused by previous owners of properties purchased by us, which liabilities may not be
covered by insurance.

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. 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. We have no coverage for
gradual, long-term pollution events. In addition, these policies do not provide coverage for all liabilities, and we cannot assure you that the insurance coverage
will  be  adequate  to  cover  claims  that  may  arise,  or  that  we  will  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.

Competition in the oil and natural gas industry is intense, which may adversely affect our ability to succeed.

The oil and natural gas industry is intensely competitive, and we compete with other companies that have greater resources than us. Many of these
companies not only explore for and produce oil and natural gas, but also carry on midstream and refining operations and market petroleum and other products
on a regional, national or worldwide basis. These companies may be able to pay more for productive oil and natural gas properties and exploratory prospects
or  define,  evaluate,  bid  for  and  purchase  a  greater  number  of  properties  and  prospects  than  our  financial  or  human  resources  permit.  In  addition,  these
companies may have a greater ability to continue exploration activities during periods of low oil and natural gas market prices. Our larger competitors may be
able to absorb the burden of present and future federal, state, local and other laws and regulations more easily than we can, which would adversely affect our
competitive position. Our ability to acquire additional properties and to discover reserves in the future will be dependent upon our ability to evaluate and
select  suitable  properties  and  to  consummate  transactions  in  a  highly  competitive  environment.  In  addition,  because  we  have  fewer  financial  and  human
resources  than  many  companies  in  our  industry,  we  may  be  at  a  disadvantage  in  bidding  for  exploratory  prospects  and  producing  oil  and  natural  gas
properties.

Our  use  of  2-D  and  3-D  seismic  data  is  subject  to  interpretation  and  may  not  accurately  identify  the  presence  of  oil  and  natural  gas,  which  could
adversely affect the results of our drilling operations.

Even  when  properly  used  and  interpreted,  2-D  and  3-D  seismic  data  and  visualization  techniques  are  only  tools  used  to  assist  geoscientists  in
identifying subsurface structures and hydrocarbon indicators and do not enable the interpreter to know whether hydrocarbons are, in fact, present in those
structures. In addition, the use of 3-D seismic and other advanced technologies requires greater predrilling expenditures than traditional drilling strategies, and
we could incur losses as a result of such expenditures. As a result, our drilling activities may not be successful or economical.

We may not be able to keep pace with technological developments in our industry.

The oil and natural gas industry is characterized by rapid and significant technological advancements and introductions of new products and services
using  new  technologies.  As  others  use  or  develop  new  technologies,  we  may  be  placed  at  a  competitive  disadvantage  or  may  be  forced  by  competitive
pressures to implement those new technologies at substantial costs. In addition, other oil and natural gas companies may have greater financial, technical and
personnel resources that allow them to enjoy technological advantages and that may in the future allow them to implement new technologies before we can.
We may not be able to respond to these competitive pressures or implement new technologies on a timely basis or at an acceptable cost. If one or more of the
technologies we use now or in the future were to become obsolete, our business, financial condition or results of operations could be materially and adversely
affected.

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 Sarbanes-Oxley Act. Section 404 requires
that we document and test our internal control over financial reporting and issue management’s assessment of our internal control over financial reporting.
This section also requires that our independent registered public accounting firm opine on those internal controls. If we fail to comply with the requirements
of Section 404 of the Sarbanes-Oxley Act, or if we or our auditors identify and report material weaknesses in 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, results
of operations and financial condition.

Increased costs of capital could adversely affect our business.

Our business could be harmed by factors such as the availability, terms and cost of capital, increases in interest rates or a reduction in our credit
rating. Changes in any one or more of these factors could cause our cost of doing business to increase, limit our access to capital, limit our ability to pursue
acquisition opportunities, reduce our cash flows available for drilling and place us at a competitive disadvantage. Continuing disruptions and 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  activities.  We
require continued

45

Table of Contents

access to capital. A significant reduction in the availability of credit could materially and adversely affect our ability to achieve our planned growth and cash
flows.

We recorded stock-based compensation expense in 2019, 2018 and 2017, and we may incur substantial additional compensation expense related to our
future grants of stock compensation which may have a material negative impact on our operating results for the foreseeable future.

As a result of outstanding stock-based compensation awards, for the years ended December 31, 2019, 2018 and 2017 we incurred $65 million, $37
million and $34 million, respectively, of stock based compensation expense, of which we capitalized $17 million, $10 million and $9 million  respectively,
pursuant  to  the  full  cost  method  of  accounting  for  oil  and  natural  gas  properties.  In  addition,  our  compensation  expenses  may  increase  in  the  future  as
compared to our historical expenses because of the costs associated with our existing and possible future incentive plans. These additional expenses could
adversely affect our net income. The future expense will be dependent upon the number of share-based awards issued and the fair value of the options or
shares of common stock at the date of the grant; however, they may be significant. We will recognize expenses for restricted stock awards and stock options
generally over the vesting period of awards made to recipients.

Loss of our information and computer systems could adversely affect our business.

We  are  heavily  dependent  on  our  information  systems  and  computer  based  programs,  including  our  well  operations  information,  seismic  data,
electronic data processing and accounting data. If any of such programs or systems were to fail or create erroneous information in our hardware or software
network infrastructure, possible consequences include our loss of communication links, inability to find, produce, process and sell oil and natural gas and
inability to automatically process commercial transactions or engage in similar automated or computerized business activities. Any such consequence could
have a material adverse effect on our business.

A terrorist attack or armed conflict could harm our business.

Terrorist  activities,  anti-terrorist  efforts  and  other  armed  conflicts  involving  the  United  States  or  other  countries  may  adversely  affect  the  United
States  and  global  economies  and  could  prevent  us  from  meeting  our  financial  and  other  obligations.  If  any  of  these  events  occur,  the  resulting  political
instability and societal disruption could reduce overall demand for oil and natural gas causing a reduction in our revenues. Oil and natural gas related facilities
could be direct targets of terrorist attacks, and our operations could be adversely impacted if infrastructure integral to our customers’ operations is destroyed
or  damaged.  Costs  for  insurance  and  other  security  may  increase  as  a  result  of  these  threats,  and  some  insurance  coverage  may  become  more  difficult  to
obtain, if available at all.

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 exploration, development, production,
and  processing  activities.  For  example,  the  oil  and  natural  gas  industry  depends  on  digital  technologies  to  interpret  seismic  data,  manage  drilling  rigs,
production equipment and gathering systems, conduct reservoir modeling and reserves estimation, and process and record financial and operating 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,  networks,  and  those  of  its  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 and other information, or other disruption of its business operations. In addition, certain cyber incidents, such as
surveillance,  may  remain  undetected  for  an  extended  period.  Our  systems  and  insurance  coverage  for  protecting  against  cyber  security  risks  may  not  be
sufficient.  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 any vulnerability to cyber incidents. We do not maintain specialized insurance for possible liability resulting from a
cyberattack on our assets that may shut down all or part of our business.

Risks Related to Our Indebtedness

References in this section to “us, “we” or “our” shall mean Diamondback Energy, Inc. and Diamondback O&G LLC, collectively, unless otherwise

specified.

We have relied in the past, and we may rely from time to time in the future, on borrowings under our revolving credit facility to fund a portion of our
capital expenditures. Unless we are able to repay borrowings under the revolving credit facility with

46

Table of Contents

cash flow from operations and proceeds from equity or debt offerings, implementing our capital programs may require an increase in our total leverage
through  additional  debt  issuances.  In  addition,  a  reduction  in  availability  under  our  revolving  credit  facility  and  the  inability  to  otherwise  obtain
financing for our capital programs could require us to curtail our capital expenditures.

We have historically relied on availability under our revolving credit facility to fund a portion of our capital expenditures. We expect that we will
continue to fund a portion of our capital expenditures with borrowings under the revolving credit facility, cash flow from operations and the proceeds from
debt and equity offerings. In the past, we have created availability under the revolving credit facility by repaying outstanding borrowings with the proceeds
from debt or equity offerings. We cannot assure you that we will choose to or be able to access the capital markets to repay any such future borrowings.
Instead, we may be required or choose to finance our capital expenditures through additional debt issuances, which would increase our total amount of debt
outstanding. If the availability under the revolving credit facility were reduced, and we were otherwise unable to secure other sources of financing, we may be
required  to  curtail  our  capital  expenditures,  which  could  limit  our  ability  to  fund  our  drilling  activities  and  acquisitions  or  otherwise  finance  the  capital
expenditures necessary to replace our reserves.

Our substantial level of indebtedness could adversely affect our financial condition and prevent us from fulfilling our obligations under our indebtedness.

As of December 31, 2019, we had total long-term debt of $5.4 billion, including $4.3 billion outstanding under our 5.375% Senior Notes due 2025,
which we refer to as the 2025 Notes, the Energen Notes, our 2.875% Senior Notes due 2024, our 3.250% Senior Notes due 2026 and our 3.500% Senior
Notes due 2029, which are collectively referred to, together with the 2025 Notes, as the senior notes, and $13 million outstanding under our revolving credit
facility, and we had $1.99 billion available for borrowing under our revolving credit facility. As of December 31, 2019, Energen, one of our subsidiaries, had
$539 million,  which  are  collectively  referred  to  as  the  Energen  Notes.  As  of  December 31, 2019,  Viper  LLC,  one  of  our  subsidiaries,  had  $97 million  in
outstanding borrowings, and $678 million available for borrowing, under its revolving credit facility and $500 million outstanding under its 5.375% Senior
Notes due 2027. As of December 31, 2019, Rattler LLC, one of our subsidiaries, had $424 million in outstanding borrowings, and $176 million available for
borrowing, under its revolving credit facility. We may in the future incur significant additional indebtedness under our revolving credit facility or otherwise in
order to make acquisitions, to develop our properties or for other purposes. Our level of indebtedness could have important consequences to you and affect
our operations in several ways, including the following:

•

•

•

•

•

•

•

our high level of indebtedness could make it more difficult for us to satisfy our obligations with respect to our debt instruments, including any
repurchase obligations that may arise thereunder;

a significant portion of our cash flows could be used to service our indebtedness, which could reduce the funds available to us for operations and
other purposes;

our high level of debt could increase our vulnerability to general adverse economic and industry conditions;

the covenants contained in the agreements governing certain of our outstanding indebtedness will limit our ability to borrow additional

funds, dispose of assets, pay dividends and make certain investments;

our high level of debt may place us at a competitive disadvantage compared to our competitors that are less leveraged and, therefore, may be
able to take advantage of opportunities that our indebtedness would prevent us from pursuing;

our debt covenants may also limit management’s discretion in operating our business and our flexibility in planning for, and reacting to, changes
in the economy and in our industry;

our high level of debt could limit our ability to access the capital markets to raise capital on favorable terms;

our  high  level  of  debt  may  impair  our  ability  to  obtain  additional  financing  in  the  future  for  working  capital,  capital  expenditures,

acquisitions, general corporate or other purposes; and

we may be vulnerable to interest rate increases, as our borrowings under our revolving credit facility are at variable interest rates.

Our high level of indebtedness increases the risk that we may default on our debt obligations. Our ability to meet our debt obligations and to reduce
our level of indebtedness depends on our future performance. General economic conditions, oil and natural gas prices and financial, business and other factors
affect our operations and our future performance. Many of these factors are beyond our control. We may not be able to generate sufficient cash flows to pay
the interest on our debt, and future working capital, borrowings or equity financing may not be available to pay or refinance such debt. Factors that will affect
our

47

Table of Contents

ability to raise cash through an offering of our capital stock or a refinancing of our debt include financial market conditions, the value of our assets and our
performance at the time we need capital.

Restrictive covenants in certain of our existing and future debt instruments may limit our ability to respond to changes in market conditions or pursue
business opportunities.

Certain of our debt instruments contain, and the terms of any future indebtedness may contain, restrictive covenants that limit our ability to, among

other things:

•

incur or guarantee additional indebtedness;

• make certain investments;

•

•

•

create liens;

sell or transfer assets;

issue preferred stock;

• merge or consolidate with another entity;

•

•

•

pay dividends or make other distributions;

create unrestricted subsidiaries; and

engage in transactions with affiliates.

Under our revolving credit facility we are allowed, among other things, to designate one or more of our subsidiaries as “unrestricted subsidiaries”
that are not subject to certain restrictions contained in the revolving credit facility. Under our revolving credit facility, we designated Viper, Viper’s general
partner,  Viper’s  subsidiary,  Rattler,  Rattler’s  general  partner  and  Rattler’s  subsidiaries  as  unrestricted  subsidiaries,  and  upon  such  designation,  they  were
automatically released from any and all obligations under the revolving credit facility, including the related guaranty. Further Viper, Viper’s general partner,
Viper’s subsidiaries, Rattler, Rattler’s general partner and Rattler’s subsidiaries are designated as unrestricted subsidiaries under the indentures governing our
outstanding senior notes.

We and our subsidiaries may be prevented from taking advantage of business opportunities that arise because of the limitations imposed on us by the
restrictive covenants and financial covenants contained in our and our subsidiaries’ debt instruments. As an example, our revolving credit facility requires us
to maintain a total net debt to capitalization ratio. The requirement that we and our subsidiaries comply with these provisions may materially adversely affect
our and our subsidiaries ability to react to changes in market conditions, take advantage of business opportunities we believe to be desirable, obtain future
financing, fund needed capital expenditures or withstand a continuing or future downturn in our business.

A  breach  of  any  of  these  restrictive  covenants  could  result  in  default  under  the  applicable  debt  instrument.  If  default  occurs  under  our  revolving
credit facility, the lenders thereunder may elect to declare all borrowings outstanding, together with accrued interest and other fees, to be immediately due and
payable, which would result in an event of default under the indentures governing our senior notes. The lenders will also have the right in these circumstances
to terminate any commitments they have to provide further borrowings. If the indebtedness under our revolving credit facility and our senior notes were to be
accelerated, we cannot assure you that our assets would be sufficient to repay in full that indebtedness.

Our indebtedness is structurally subordinated to the indebtedness and other liabilities of our subsidiaries, and our obligations are not obligations of any
of our subsidiaries.

Our senior indebtedness obligations are obligations exclusively of Diamondback Energy, Inc. and Diamondback O&G LLC, and not of any of our
other subsidiaries. None of our subsidiaries is a guarantor of our senior indebtedness. Any assets of our subsidiaries will not be directly available to satisfy the
claims  of  our  creditors,  including  lenders  under  our  revolving  credit  facility  and  holders  of  the  senior  notes.  Except  to  the  extent  we  are  a  creditor  with
recognized  claims  against  our  subsidiaries,  all  claims  of  creditors  of  our  subsidiaries  will  have  priority  over  our  equity  interests  in  such  subsidiaries  (and
therefore the claims of our creditors, including lenders under our revolving credit facility and holders of the senior notes) with respect to the assets of such
subsidiaries. Even if we are recognized as a creditor of one or more of our subsidiaries, our claims would still be effectively

48

Table of Contents

subordinated to any security interests in the assets of any such subsidiary and to any indebtedness or other liabilities of any such subsidiary senior to our
claims.  Consequently,  our  senior  indebtedness  will  be  structurally  subordinated  to  all  indebtedness  and  other  liabilities  of  any  of  our  subsidiaries  and  any
subsidiaries that we may in the future acquire or establish, As of December 31, 2019, Energen, one of our subsidiaries, had an aggregate of $539 million of
notes, which are collectively referred to as the Energen Notes. As of December 31, 2019, Viper LLC, one of our subsidiaries, had $97 million in outstanding
borrowings, and $678 million available for borrowing, under its revolving credit facility and $500 million outstanding under its 5.375%  Senior  Notes  due
2027. As of December 31, 2019, Rattler LLC, one of our subsidiaries, had $424 million in outstanding borrowings, and $176 million available for borrowing,
under its revolving credit facility.

Servicing our indebtedness requires a significant amount of cash, and we may not have sufficient cash flow from our business to pay our substantial
indebtedness.

Our ability to make scheduled payments of the principal, to pay interest on or to refinance our indebtedness, including our senior notes, depends on
our future performance, which is subject to economic, financial, competitive and other factors beyond our control. Our business may not generate cash flow
from operations in the future sufficient to service our debt and make necessary capital expenditures. If we are unable to generate such cash flow, we may be
required to adopt one or more alternatives, such as reducing or delaying capital expenditures, selling assets, restructuring debt or obtaining additional equity
capital  on  terms  that  may  be  onerous  or  highly  dilutive.  However,  we  cannot  assure  you  that  undertaking  alternative  financing  plans,  if  necessary,  would
allow us to meet our debt obligations. In the absence of such cash flows, we could have substantial liquidity problems and might be required to sell material
assets or operations to attempt to meet our debt service and other obligations. The indenture governing the 2025 Notes restricts our ability to use the proceeds
from asset sales. We may not be able to consummate those asset sales to raise capital or sell assets at prices that we believe are fair, and proceeds that we do
receive may not be adequate to meet any debt service obligations then due. Our ability to refinance our indebtedness will depend on the capital markets and
our financial condition at the time. We may not be able to engage in any of these activities or engage in these activities on desirable terms, which could result
in a default on our debt obligations and have an adverse effect on our financial condition.

We depend on our subsidiaries for dividends, distributions and other payments.

We  depend  on  our  subsidiaries  for  dividends,  distributions  and  other  payments.  We  are  a  legal  entity  separate  and  distinct  from  our  operating
subsidiaries. There are statutory and regulatory limitations on the payment of dividends or distributions by certain of our subsidiaries to us. If our subsidiaries
are unable to make dividend or distribution payments to us and sufficient cash or liquidity is not otherwise available, we may not be able to make dividend
payments to our stockholders or principal and interest payments on our outstanding indebtedness.

We and our subsidiaries may still be able to incur substantial additional indebtedness in the future, which could further exacerbate the risks that we and
our subsidiaries face.

We and our subsidiaries may be able to incur substantial additional indebtedness in the future. The terms of our and our subsidiaries’ revolving credit
facilities and the indentures restrict, but in each case do not completely prohibit, us from doing so. As of December 31, 2019, we had $13 million outstanding
under our revolving credit facility, and we had $1.99 billion available for borrowing under our revolving credit facility As of December 31, 2019, Viper LLC
had $97 million in outstanding borrowings, and $678 million available for borrowing, under its revolving credit facility. As of December 31, 2019, Rattler
LLC  had  $424  million  in  outstanding  borrowings,  and  $176  million  available  for  borrowing,  under  its  revolving  credit  facility.  Further,  the  indentures
governing our and our subsidiaries’ notes allow us to issue additional notes incur certain other additional debt and to have subsidiaries that do not guarantee
the senior notes and which may incur additional debt, which would be structurally senior to the senior notes. In addition, the indentures governing the senior
notes do not prevent us from incurring other liabilities that do not constitute indebtedness. If we or a guarantor incur any additional indebtedness that ranks
equally with the senior notes (or with the guarantees thereof), including additional unsecured indebtedness or trade payables, the holders of that indebtedness
will be entitled to share ratably with holders of the senior notes in any proceeds distributed in connection with any insolvency, liquidation, reorganization,
dissolution or other winding-up of us or a guarantor. If new debt or other liabilities are added to our current debt levels, the related risks that we and our
subsidiaries now face could intensify.

If we experience liquidity concerns, we could face a downgrade in our debt ratings which could restrict our access to, and negatively impact the terms of,
current or future financings or trade credit.

Our ability to obtain financings and trade credit and the terms of any financings or trade credit is, in part, dependent on the credit ratings assigned to
our debt by independent credit rating agencies. We cannot provide assurance that any of our current ratings will remain in effect for any given period of time
or that a rating will not be lowered or withdrawn entirely by a rating agency if, in its judgment, circumstances so warrant. Factors that may impact our credit
ratings include debt levels, planned asset

49

Table of Contents

purchases or sales and near-term and long-term production growth opportunities, liquidity, asset quality, cost structure, product mix and commodity pricing
levels. A ratings downgrade could adversely impact our ability to access financings or trade credit and increase our borrowing costs.

Borrowings under our, Viper LLC’s and Rattler LLC’s revolving credit facilities expose us to interest rate risk.

Our earnings are exposed to interest rate risk associated with borrowings under our and our subsidiaries’ revolving credit facilities. The terms of our
and  our  subsidiaries’  revolving  credit  facilities  provide  for  interest  on  borrowings  at  a  floating  rate  equal  to  an  alternate  base  rate  (which  is  equal  to  the
greatest of the prime rate, the Federal Funds effective rate plus 0.50% and 3-month LIBOR plus 1.0%) or LIBOR, in each case plus the applicable margin.
The applicable margin ranges from 0.125% to 1.0% in the case of the alternative base rate and from 1.125% to 2.0%  in  the  case  of  LIBOR,  in  each  case
depending on the amount of the loan outstanding in relation to the borrowing base. Both Viper LLC’s and Rattler LLC’s revolving credit facilities provide for
interest on borrowings at floating rates, which are also tied to LIBOR. LIBOR tends to fluctuate based on multiple facts, including general short-term interest
rates, rates set by the U.S. Federal Reserve and other central banks, the supply of and demand for credit in the London interbank market and general economic
conditions. We have not hedged our interest rate exposure with respect to our floating rate debt. Accordingly, our interest expense for any particular period
will fluctuate based on LIBOR and other variable interest rates. As of December 31, 2019, we had $13 million borrowings outstanding under our revolving
credit facility. Our weighted average interest rate on borrowings under our revolving credit facility was 3.20% on December 31, 2019. Viper LLC’s weighted
average interest rate on borrowings from its revolving credit facility was 4.30% during the year ended December 31, 2019. Rattler LLC’s weighted average
interest rate on borrowings from its revolving credit facility was 2.98% during the year ended December 31, 2019. As of December 31, 2019, Viper LLC had
$97 million in outstanding borrowings, and $678 million available for borrowing, under its revolving credit facility. As of December 31, 2019, Rattler LLC
had $424 million in outstanding borrowings, and $176 million available for borrowing, under its revolving credit facility. If interest rates increase, so will our
interest costs, which may have a material adverse effect on our results of operations and financial condition.

On July 27, 2017, the U.K. Financial Conduct Authority (the authority that regulates LIBOR) announced that it intends to stop compelling banks to
submit rates for the calculation of LIBOR after 2021. It is unclear whether new methods of calculating LIBOR will be established or if LIBOR will continue
to exist after 2021. The U.S. Federal Reserve, in conjunction with the Alternative Reference Rates Committee, is considering replacing U.S. dollar LIBOR
with a newly created index. It is not possible to predict the effect of these changes, other reforms or the establishment of alternative reference rates in the
United States or elsewhere.

The corporate opportunity provisions in our certificate of incorporation could enable affiliates of ours to benefit from corporate opportunities that might
otherwise be available to us.

Risks Related to Our Common Stock

Subject to the limitations of applicable law, our certificate of incorporation, among other things:

•

•

•

permits us to enter into transactions with entities in which one or more of our officers or directors are financially or otherwise interested;

permits any of our stockholders, officers or directors to conduct business that competes with us and to make investments in any kind of property
in which we may make investments; and

provides that if any director or officer of one of our affiliates who is also one of our officers or directors becomes aware of a potential business
opportunity, transaction or other matter (other than one expressly offered to that director or officer in writing solely in his or her capacity as our
director  or  officer),  that  director  or  officer  will  have  no  duty  to  communicate  or  offer  that  opportunity  to  us,  and  will  be  permitted  to
communicate or offer that opportunity to such affiliates and that director or officer will not be deemed to have (i) acted in a manner inconsistent
with  his  or  her  fiduciary  or  other  duties  to  us  regarding  the  opportunity  or  (ii)  acted  in  bad  faith  or  in  a  manner  inconsistent  with  our  best
interests.

These provisions create the possibility that a corporate opportunity that would otherwise be available to us may be used for the benefit of one of our

affiliates.

50

Table of Contents

We have engaged in transactions with our affiliates and expect to do so in the future. The terms of such transactions and the resolution of any conflicts
that may arise may not always be in our or our stockholders’ best interests.

In the past, we have engaged in transactions with affiliated companies and may do so again in the future. These transactions, and the resolution of
any conflicts that may arise in connection with such related party transactions, including pricing, duration or other terms of service, may not always be in our
or our stockholders’ best interests.

If the price of our common stock fluctuates significantly, your investment could lose value.

Although our common stock is listed on the Nasdaq Select Global Market, we cannot assure you that an active public market will continue for our
common stock. If an active public market for our common stock does not continue, the trading price and liquidity of our common stock will be materially and
adversely affected. If there is a thin trading market or “float” for our stock, the market price for our common stock may fluctuate significantly more than the
stock market as a whole. Without a large float, our common stock would be less liquid than the stock of companies with broader public ownership and, as a
result, the trading prices of our common stock may be more volatile. In addition, in the absence of an active public trading market, investors may be unable to
liquidate their investment in us. Furthermore, the stock market is subject to significant price and volume fluctuations, and the price of our common stock
could fluctuate widely in response to several factors, including:

•

•

•

•

•

•

•

•

our quarterly or annual operating results;

changes in our earnings estimates;

investment recommendations by securities analysts following our business or our industry;

additions or departures of key personnel;

changes in the business, earnings estimates or market perceptions of our competitors;

our failure to achieve operating results consistent with securities analysts’ projections;

changes in industry, general market or economic conditions; and

announcements of legislative or regulatory changes.

The  stock  market  has  experienced  extreme  price  and  volume  fluctuations  in  recent  years  that  have  significantly  affected  the  quoted  prices  of  the
securities of many companies, including companies in our industry. The changes often appear to occur without regard to specific operating performance. The
price  of  our  common  stock  could  fluctuate  based  upon  factors  that  have  little  or  nothing  to  do  with  our  company  and  these  fluctuations  could  materially
reduce our stock price.

The  declaration  of  dividends  and  repurchases  of  our  common  stock  are  each  within  the  discretion  of  our  board  of  directors  based  upon  a  review  of
relevant  considerations,  and  there  is  no  guarantee  that  we  will  pay  any  dividends  on  or  repurchases  of  our  common  stock  in  the  future  or  at  levels
anticipated by our stockholders.

On February 13, 2018, we initiated payment of quarterly cash dividends on our common stock payable beginning with the first quarter of 2018. The
decision to pay any future dividends, however, is solely within the discretion of, and subject to approval by, our board of directors. Our board of directors’
determination with respect to any such dividends, including the record date, the payment date and the actual amount of the dividend, will depend upon our
profitability and financial condition, contractual restrictions, restrictions imposed by applicable law and other factors that the board deems relevant at the time
of such determination. Based on its evaluation of these factors, the board of directors may determine not to declare a dividend, or declare dividends at rates
that are less than currently anticipated, either of which could reduce returns to our stockholders.

In  May  2019,  our  board  of  directors  approved  a  stock  repurchase  program  to  acquire  up  to  $2  billion  of  our  outstanding  common  stock  through
December 31, 2020. This repurchase program is at the discretion of our board of directors and may be suspended from time to time, modified, extended or
discontinued by our board of directors at any time.

51

A change of control could limit our use of net operating losses.

If we were to experience an “ownership change,” as determined under Section 382 of the Code, our ability to offset taxable income arising after the
ownership  change  with  NOLs  generated  prior  to  the  ownership  change  would  be  limited,  possibly  substantially.  In  general,  an  ownership  change  would
establish an annual limitation on the amount of our pre-change NOLs we could utilize to offset our taxable income in any future taxable year to an amount
generally equal to the value of our stock immediately prior to the ownership change multiplied by the long-term tax-exempt rate. In general, an ownership
change will occur if there is a cumulative increase in our ownership of more than 50 percentage points by one or more “5% shareholders” (as defined in the
Internal Revenue Code) at any time during a rolling three-year period.

As  of  December  31,  2019,  we  had  a  net  operating  loss,  or  NOL,  carry  forward  of  approximately  $1.7  billion  for  federal  income  tax  purposes,
including $748 million acquired as part of the Energen acquisition. Although the NOL, and tax credits of $3 million, attributable to Energen’s pre-acquisition
activity  are  subject  to  an  annual  limitation  under  Section  382  of  the  Code,  we  do  not  expect  that  limitation  to  materially  impact  our  utilization  of  those
amounts

If securities or industry analysts do not publish research or reports about our business, if they adversely change their recommendations regarding our
stock or if our operating results do not meet their expectations, our stock price could decline.

The trading market for our common stock will be influenced by the research and reports that industry or securities analysts publish about us or our
business. If one or more of these analysts cease coverage of our company or fail to publish reports on us regularly, we could lose visibility in the financial
markets, which in turn could cause our stock price or trading volume to decline. Moreover, if one or more of the analysts who cover our company downgrade
our stock or if our operating results do not meet their expectations, our stock price could decline.

We may issue preferred stock whose terms could adversely affect the voting power or value of our common stock.

Our  certificate  of  incorporation  authorizes  us  to  issue,  without  the  approval  of  our  stockholders,  one  or  more  classes  or  series  of  preferred  stock
having such designations, preferences, limitations and relative rights, including preferences over our common stock respecting dividends and distributions, as
our board of directors may determine. The terms of one or more classes or series of preferred stock could adversely impact the voting power or value of our
common stock. For example, we might grant holders of preferred stock the right to elect some number of our directors in all events or on the happening of
specified events or the right to veto specified transactions. Similarly, the repurchase or redemption rights or liquidation preferences we might assign to holders
of preferred stock could affect the residual value of the common stock.

Provisions in our certificate of incorporation and bylaws and Delaware law make it more difficult to effect a change in control of the company, which
could adversely affect the price of our common stock.

The  existence  of  some  provisions  in  our  certificate  of  incorporation  and  bylaws  and  Delaware  corporate  law  could  delay  or  prevent  a  change  in
control of our company, even if that change would be beneficial to our stockholders. Our certificate of incorporation and bylaws contain provisions that may
make acquiring control of our company difficult, including:

•

•

•

•

•

•

provisions regulating the ability of our stockholders to nominate directors for election or to bring matters for action at annual meetings of our
stockholders;

limitations on the ability of our stockholders to call a special meeting and act by written consent;

the ability of our board of directors to adopt, amend or repeal bylaws, and the requirement that the affirmative vote of holders representing at
least 66 2/3% of the voting power of all outstanding shares of capital stock be obtained for stockholders to amend our bylaws;

the requirement that the affirmative vote of holders representing at least 66 2/3% of the voting power of all outstanding shares of capital stock be
obtained to remove directors;

the requirement that the affirmative vote of holders representing at least 66 2/3% of the voting power of all outstanding shares of capital stock be
obtained to amend our certificate of incorporation; and

the authorization given to our board of directors to issue and set the terms of preferred stock without the approval of our stockholders.

52

 
Table of Contents

These provisions also could discourage proxy contests and make it more difficult for you and other stockholders to elect directors and take other
corporate actions. As a result, these provisions could make it more difficult for a third party to acquire us, even if doing so would benefit our stockholders,
which may limit the price that investors are willing to pay in the future for shares of our common stock.

ITEM 1B. UNRESOLVED STAFF COMMENTS

None.

ITEM 3. LEGAL PROCEEDINGS

We are a party to various legal proceedings, disputes and claims arising in the course of our business, including those that arise from interpretation of
federal and state laws and regulations affecting the natural gas and crude oil industry, personal injury claims, title disputes, royalty disputes, contract claims,
contamination claims relating to oil and gas exploration and development and environmental claims, including claims involving assets previously sold to third
parties and no longer part of our current operations. While the ultimate outcome of the pending proceedings, disputes or claims, and any resulting impact on
us,  cannot  be  predicted  with  certainty,  we  believe  that  none  of  these  matters,  if  ultimately  decided  adversely,  will  have  a  material  adverse  effect  on  our
financial condition, cash flows or results of operations.

Dividend Policy 

On  February  13,  2018,  we  announced  the  initiation  of  an  annual  cash  dividend  in  the  amount  of  $0.50  per  share  of  our  common  stock  payable
quarterly which began with the first quarter of 2018. Beginning with the first quarter of 2019, the annual cash dividend was increased to $0.75 per share of
our common stock. Additionally, beginning with the fourth quarter of 2019, the annual cash dividend was increased to $1.50 per share of our common stock.
The  decision  to  pay  any  future  dividends  is  solely  within  the  discretion  of,  and  subject  to  approval  by,  our  board  of  directors.  Our  board  of  directors’
determination with respect to any such dividends, including the record date, the payment date and the actual amount of the dividend, will depend upon our
profitability and financial condition, contractual restrictions, restrictions imposed by applicable law and other factors that the board deems relevant at the time
of such determination.

(2) Consolidated  Adjusted  EBITDA  is  a  supplemental  non-GAAP  financial  measure.  For  our  definition  of  Consolidated  Adjusted  EBITDA  and  a

reconciliation of Consolidated Adjusted EBITDA to net income (loss) see “–Non-GAAP financial measure and reconciliation” below.

Non-GAAP financial measure and reconciliation

Adjusted EBITDA is a supplemental non-GAAP financial measure that is used by management and external users of our financial statements, such
as  industry  analysts,  investors,  lenders  and  rating  agencies.  We  define  Adjusted  EBITDA  as  net  income  (loss)  plus  non-cash  (gain)  loss  on  derivative
instruments, net, net interest expense, depreciation, depletion and amortization expense, impairment of oil and natural gas properties, non-cash equity-based
compensation  expense,  capitalized  equity-based  compensation  expense,  asset  retirement  obligation  accretion  expense,  (gain)  loss  on  revaluation  of
investment, loss on extinguishment of debt, merger and integration expense, income tax (benefit) provision and non-controlling interest in net (income) loss.
Adjusted EBITDA is not a measure of net income (loss) as determined by GAAP. Management believes Adjusted EBITDA is useful because it allows it to
more effectively evaluate our operating performance and compare the results of our operations from period to period without regard to our financing methods
or capital structure. We add the items listed above to net income (loss) in arriving at Adjusted EBITDA because these amounts can vary substantially from
company  to  company  within  our  industry  depending  upon  accounting  methods  and  book  values  of  assets,  capital  structures  and  the  method  by  which  the
assets  were  acquired.  Adjusted  EBITDA  should  not  be  considered  as  an  alternative  to,  or  more  meaningful  than,  net  income  (loss)  as  determined  in
accordance  with  GAAP  or  as  an  indicator  of  our  operating  performance  or  liquidity.  Certain  items  excluded  from  Adjusted  EBITDA  are  significant
components in understanding and assessing a company’s financial performance, such as a company’s cost of capital and tax structure, as well as the historic
costs of depreciable assets, none of which are components of Adjusted EBITDA. Our computations of Adjusted EBITDA may not be comparable to other
similarly titled measure of other companies or to such measure in our revolving credit facility or any of our other contracts.

ITEM 7.         MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The  following  discussion  and  analysis  should  be  read  in  conjunction  with  our  consolidated  financial  statements  and  notes  thereto  appearing
elsewhere  in  this  Annual  Report  on  Form  10–K.  The  following  discussion  contains  “forward-looking  statements”  that  reflect  our  future  plans,  estimates,
beliefs, and expected performance. Actual results and the timing of events may differ materially from those contained in these forward-looking statements due
to a number of factors. See Item 1A. “Risk Factors” and “Cautionary Statement Regarding Forward-Looking Statements.”

Overview

We operate in two business segments: (i) the upstream segment, which is engaged in the acquisition, development, exploration and exploitation of
unconventional, onshore oil and natural gas reserves in the Permian Basin in West Texas and (ii) through our subsidiary, Rattler, the midstream operations
segment, which is focused on ownership, operation, development and acquisition of the midstream infrastructure assets in the Midland and Delaware Basins
of the Permian Basin.

Upstream Operations

In  our  upstream  segment,  our  activities  are  primarily  directed  at  the  horizontal  development  of  the  Wolfcamp  and  Spraberry  formations  in  the
Midland Basin and the Wolfcamp and Bone Spring formations in the Delaware Basin. We intend to continue to develop our reserves and increase production
through  development  drilling  and  exploitation  and  exploration  activities  on  our  multi-year  inventory  of  identified  potential  drilling  locations  and  through
acquisitions that meet our strategic and financial objectives, targeting oil-weighted reserves.

As of December 31, 2019, we had approximately 382,337 net acres, which primarily consisted of approximately 195,461 net acres in the Midland
Basin and approximately 155,296 net acres in the Delaware Basin. As of December 31, 2019, we had an estimated 12,310 gross horizontal locations that we
believe to be economic at $60.00 per Bbl West Texas Intermediate, or WTI.

In addition, our publicly traded subsidiary Viper owns mineral interests underlying approximately 814,224 gross acres and 24,304 net royalty acres
in the Permian Basin and Eagle Ford Shale. Approximately 50% of these net royalty acres are operated by us. We own Viper’s general partner and, together
with one of our subsidiaries, approximately 58% of the limited partner interest in Viper, represented by common units and Class B units. We, as the holder of
the Class B units in Viper and Viper’s general partner, as the holder of the general partner interest, are entitled to receive cash preferred distributions equal to
8% per annum on the outstanding amount of their respective capital contributions payable quarterly.

Midstream Operations

In  our  midstream  operations  segment,  Rattler’s  crude  oil  infrastructure  assets  consist  of  gathering  pipelines  and  metering  facilities,  which
collectively gather crude oil for its customers. Rattler’s facilities gather crude oil from horizontal and vertical wells in our ReWard, Spanish Trail, Pecos and
Fivestones areas within the Permian Basin. Rattler’s natural gas gathering and compression system consists of gathering pipelines, compression and metering
facilities,  which  collectively  service  the  production  from  our  Pecos  area  assets  within  the  Permian  Basin.  Rattler’s  water  sourcing  and  distribution  assets
consists of water wells, frac pits, pipelines and water treatment facilities, which collectively gather and distribute water from Permian Basin aquifers to the
drilling and completion sites through buried pipelines and temporary surface pipelines. Rattler’s gathering and disposal system spans approximately 474 miles
and consists of gathering pipelines along with produced water disposal, or PWD, wells and facilities which collectively gather and dispose of produced water
from operations throughout our Permian Basin acreage.

We  have  entered  into  multiple  fee-based  commercial  agreements  with  Rattler,  each  with  an  initial  term  ending  in  2034,  utilizing  Rattler’s
infrastructure  assets  or  its  planned  infrastructure  assets  to  provide  an  array  of  essential  services  critical  to  our  upstream  operations  in  the  Delaware  and
Midland Basins. Our agreements with Rattler include substantial acreage dedications.

2019 Transactions and Recent Developments

Rattler Midstream LP

Rattler  is  a  publicly  traded  Delaware  limited  partnership,  the  common  units  of  which  are  listed  on  the  Nasdaq  Global  Select  Market  under  the
symbol “RTLR”. Rattler was formed by us in July 2018 to own, operate, develop and acquire midstream infrastructure assets in the Midland and Delaware
Basins of  the  Permian  Basin.  Rattler  Midstream  GP  LLC,  or  Rattler’s  General  Partner,  a  wholly-owned  subsidiary  of  us,  serves  as  the  general  partner  of
Rattler. As of December 31, 2019, we owned approximately 71% of Rattler’s total units outstanding.

In May 2019, Rattler completed its initial public offering, which we refer to as the Rattler Offering. Prior to the completion of the Rattler Offering,
we owned all of the general and limited partner interests in Rattler. The Rattler Offering consisted of an aggregate of 43,700,000 common units representing
approximately 29% of the limited partner interests in Rattler at a price to the public of $17.50 per common unit, which included 5,700,000 common units
issued  pursuant  to  an  option  to  purchase  additional  common  units  granted  to  the  underwriters  on  the  same  terms  which  closed  on  May  30,  2019.  Rattler
received net proceeds of approximately $720 million from the sale of these common units, after deducting offering expenses and underwriting discounts and
commissions.

In connection with the completion of the Rattler Offering, Rattler (i) issued 107,815,152 Class B units representing an aggregate 71% voting limited
partner interest in Rattler in exchange for a $1 million cash contribution from us, (ii) issued a general partner interest in Rattler to Rattler’s general partner, in
exchange for a $1 million cash contribution from Rattler’s general partner, and (iii) caused Rattler LLC to make a distribution of approximately $727 million
to us. We, as the beneficial holder of the Class B units, and Rattler’s general partner, as the holder of the general partner interest, are entitled to receive cash
preferred distributions equal to 8% per annum on the outstanding amount of their respective $1 million capital contributions, payable quarterly.

Fourth Quarter 2019 Dividend Declaration and Increase

On February 14, 2020, our board of directors declared a cash dividend for the fourth quarter of 2019 of $0.3750 per share of common stock, payable
on March 10, 2020 to our stockholders of record at the close of business on March 3, 2020, representing an increase of $0.1875 per share from the previously
paid quarterly dividend.

Stock Repurchase Program

In  May  2019,  our  board  of  directors  approved  a  stock  repurchase  program  to  acquire  up  to  $2 billion  of  our  outstanding  common  stock  through
December 31, 2020. This repurchase program is another component of our capital return program that includes the quarterly dividend discussed above. We
anticipate that the repurchase program will be funded primarily by free cash flow generated from operations and liquidity events such as the sale of assets.
Purchases  under  the  repurchase  program  may  be  made  from  time  to  time  in  open  market  or  privately  negotiated  transactions,  and  are  subject  to  market
conditions,  applicable  legal  requirements,  contractual  obligations  and  other  factors.  The  repurchase  program  does  not  require  us  to  acquire  any  specific
number of shares. This repurchase program may be suspended from time to time, modified, extended or discontinued by the board of directors at any time.
During the year ended December 31, 2019, we repurchased approximately $598 million of common stock under our repurchase program. As of December 31,
2019, $1.4 billion remains available for use to repurchase shares under our common stock repurchase program.

Divestiture of Certain Conventional and Non-Core Assets Acquired from Energen

On May 23, 2019, we completed our divestiture of 6,589 net acres of certain non-core Permian assets, which we acquired in the Energen merger, for
an  aggregate  sale  price  of  $37 million.  This  divestiture  did  not  result  in  a  gain  or  loss  because  it  did  not  have  a  significant  effect  on  our  reserve  base  or
depreciation, depletion and amortization rate.

On July 1, 2019, we completed our divestiture of 103,750 net acres of certain conventional and non-core Permian assets, which we acquired in the
Energen merger, for an aggregate sale price of $285 million. This divestiture did not result in a gain or loss because it did not have a significant effect on our
reserve base or depreciation, depletion and amortization rate.

Viper’s Equity Offering

On March 1, 2019, Viper completed an underwritten public offering of 10,925,000 common units, which included 1,425,000 common units issued
pursuant to an option to purchase additional common units granted to the underwriters. Following this offering, we owned approximately 54% of Viper’s total
units then outstanding. Viper received net proceeds from this offering

59

Table of Contents

of  approximately  $341 million,  after  deducting  underwriting  discounts  and  commissions  and  estimated  offering  expenses.  Viper  used  the  net  proceeds  to
purchase units of Viper LLC. Viper LLC in turn used the net proceeds to repay a portion of the outstanding borrowings under its revolving credit facility and
finance acquisitions during the period.

Drop-Down

On  October  1,  2019,  we  completed  a  transaction  to  divest  certain  mineral  and  royalty  interests  to  Viper  for  18.3 million of Viper’s newly-issued
Class  B  units,  18.3  million  newly-issued  units  of  Viper  LLC  with  a  fair  value  of  $497  million  and  $190  million  in  cash,  after  giving  effect  to  closing
adjustments for net title benefits, which we refer to as the Drop-Down. The mineral and royalty interests divested in the Drop-Down represent approximately
5,490  net  royalty  acres  across  the  Midland  and  Delaware  Basins,  of  which  over  95%  are  operated  by  us,  and  have  an  average  net  royalty  interest  of
approximately 3.2%.

Increase in the Borrowing Base under Viper LLC’s Revolving Credit Facility

In  connection  with  Viper  LLC’s  fall  redetermination  in  November  2019,  the  borrowing  base  under  Viper  LLC’s  revolving  credit  facility  was

increased from $725 million to $775 million.

Viper’s Notes Offering

On October 16, 2019, Viper completed an offering, which we refer to as the Viper Notes Offering, of $500 million in aggregate principal amount of
its 5.375% senior notes due 2027, which we refer to as the Viper Notes. Viper received net proceeds of approximately $490 million from the Viper Notes
Offering.  Viper  loaned  the  gross  proceeds  to  Viper  LLC.  Viper  LLC  used  the  proceeds  from  the  Viper  Notes  Offering  to  pay  down  borrowings  under  its
revolving credit facility.

December 2019 Notes Offering

On December 5, 2019, we issued $1.0 billion in aggregate principal amount of 2.875% senior notes due 2024, which we refer to as the 2024 notes,
$800  million  in  aggregate  principal  amount  of  3.250%  senior  notes  due  2026,  which  we  refer  to  as  the  2026  notes,  and  $1.2  billion  aggregate  principal
amount of 3.500% senior notes due 2029, which we refer to as the 2029 notes and, together with the 2024 notes and the 2026 notes, the December 2019
Notes. The 2024 notes will mature on December 1, 2024, the 2026 notes will mature on December 1, 2026 and the 2029 notes will mature on December 1,
2029. Interest will accrue and be payable semi-annually, in arrears on June 1 and December 1 of each year, commencing on June 1, 2020. The December 2019
Notes are fully and unconditionally guaranteed by Diamondback O&G LLC.

Redemption of the Outstanding 4.750% Senior Notes.

On December 20, 2019, we redeemed all of our then outstanding 4.750% Senior Notes due 2024, which we refer to as the 4.750% senior notes, with

a portion of our net proceeds from the issuance of the December 2019 Notes.

Operational Update

Our development program is focused entirely within the Permian Basin, where we continue to focus on long-lateral multi-well pad development. Our
horizontal  development  consists  of  multiple  targeted  intervals,  primarily  within  the  Wolfcamp  and  Spraberry  formations  in  the  Midland  Basin  and  the
Wolfcamp and Bone Springs formations in the Delaware Basin.

We are operating 23 drilling rigs now including two rigs drilling produced water disposal wells and currently intend to operate between 20 and 23

drilling rigs in 2020 on average across our asset base in the Midland and Delaware Basins.

In the Midland Basin, we continued to have positive results across our core development areas located within Midland, Martin, Howard, Glasscock

and Andrews counties, where development has primarily focused on drilling long-lateral, multi-well pads targeting the Spraberry and Wolfcamp formations.

In  the  Delaware  Basin,  we  have  now  drilled  and  completed  a  significant  number  of  wells  in  Pecos,  Reeves  and  Ward  counties  targeting  the
Wolfcamp A, which we believe has been de-risked across a significant portion of our total acreage position and remains our primary development target. In
2020, we expect to focus development on these areas.

We continue to focus on low cost operations and best in class execution. To combat potential fluctuation in service costs, we have looked to lock in
pricing for dedicated activity levels and will continue to seek opportunities to control additional well cost where possible. Our 2020 drilling and completion
budget accounts for capital costs that we believe cover potential increases in our service costs during the year.

60

 
Table of Contents

In 2020, we remain focused on navigating our industry challenges by staying disciplined, improving our industry-leading cost structure, growing
production, increasing environmental transparency and returning more cash to our stockholders as evidenced by our quarterly dividend increase beginning
with the fourth quarter of 2019.

2020 Capital Budget

We have currently budgeted a 2020 total capital spend of $2.8 billion to $3.0 billion, consisting of $2.45 billion to $2.6 billion for horizontal drilling
and  completions  including  non-operated  activity,  $200 million  to  $225 million  for  midstream  investments,  excluding  joint  venture  investments,  and  $150
million to $175 million for infrastructure and other expenditures, excluding the cost of any leasehold and mineral interest acquisitions. We expect to drill and
complete 320 to 360 gross horizontal wells in 2020. Should commodity prices weaken further or remain weak for an extended period of time, we intend to act
responsibly and, consistent with our prior practices, reduce capital spending. If commodity prices strengthen, we intend to grow oil production within our
2020 budget and return cash to our stockholders or pay down indebtedness.

Reserves and pricing

Ryder  Scott  prepared  estimates  of  our  proved  reserves  at  December  31,  2019  and  2018  (which  include  estimated  proved  reserves  attributable  to
Viper). The prices used to estimate proved reserves for all periods did not give effect to derivative transactions, were held constant throughout the life of the
properties and have been adjusted for quality, transportation fees, geographical differentials, marketing bonuses or deductions and other factors affecting the
price received at the wellhead.

In our upstream segment, our main sources of revenues are the sale of oil and natural gas production, as well as the sale of natural gas liquids that are

extracted from our natural gas during processing.

In  our  midstream  operations  segment,  our  results  are  primarily  driven  by:  the  volumes  of  crude  oil  that  Rattler  gathers,  transports  and  delivers;
natural  gas  that  Rattler  gathers,  compresses,  transports  and  delivers;  water  that  Rattler  sources,  transports  and  delivers;  and  produced  water  that  Rattler
gathers, transports and disposes of, and the fees Rattler charges per unit of throughput for our midstream services.

Since  our  production,  in  our  exploration  and  production  business,  consists  primarily  of  oil,  our  revenues  are  more  sensitive  to  fluctuations  in  oil
prices  than  they  are  to  fluctuations  in  natural  gas  or  natural  gas  liquids  prices.  Viper,  as  the  owner  of  mineral  interests,  is  also  indirectly  exposed  to
fluctuations  in  commodity  prices.  Oil,  natural  gas  and  natural  gas  liquids  prices  have  historically  been  volatile.  Lower  commodity  prices  may  not  only
decrease our revenues, but also potentially the amount of oil and natural gas that we can produce economically. Lower oil and natural gas prices may also
result in a reduction in the borrowing base under our credit agreement, which may be redetermined at the discretion of our lenders.

In our midstream operations business, we have indirect exposure to commodity price risk in that persistent low commodity prices may cause us or
Rattler’s other customers to delay drilling or shut in production, which would reduce the volumes available for gathering and processing by our infrastructure
assets. If we or Rattler’s other customers delay drilling or temporarily shut in production due to persistently low commodity prices or for any other reason, our
revenue in the midstream operations segment could decrease, as Rattler’s commercial agreements do not contain minimum volume commitments.

Principal components of our cost structure

Lease operating expenses. These are daily costs incurred to bring oil and natural gas out of the ground and to the market, together with the daily
costs incurred to maintain our producing properties. Such costs also include maintenance, repairs and workover expenses related to our oil and natural gas
properties.

Production and ad valorem taxes. Production taxes are paid on produced oil and natural gas based on a percentage of revenues from products sold at
fixed  rates  established  by  federal,  state  or  local  taxing  authorities.  Where  available,  we  benefit  from  tax  credits  and  exemptions  in  our  various  taxing
jurisdictions. We are also subject to ad valorem taxes in the counties where our production is located. Ad valorem taxes are generally based on the valuation
of our oil and gas properties.

General  and  administrative  expenses.  These  are  costs  incurred  for  overhead,  including  payroll  and  benefits  for  our  corporate  staff,  costs  of
maintaining our headquarters, costs of managing our production and development operations, franchise taxes, audit and other fees for professional services
and legal compliance.

Midstream services expense. These are costs incurred to operate and maintain our oil and natural gas gathering and transportation systems, natural

gas lift, compression infrastructure and water transportation facilities.

Depreciation, depletion and amortization. Under the full cost accounting method, we capitalize costs within a cost center and then systematically
expense those costs on a units of production basis based on proved oil and natural gas reserve quantities. We calculate depletion on the following types of
costs: (i) all capitalized costs, other than the cost of investments in unproved properties and major development projects for which proved reserves cannot yet
be  assigned,  less  accumulated  amortization;  (ii)  the  estimated  future  expenditures  to  be  incurred  in  developing  proved  reserves;  and  (iii)  the  estimated
dismantlement  and  abandonment  costs,  net  of  estimated  salvage  values.  Depreciation  of  other  property  and  equipment  is  computed  using  the  straight  line
method over their estimated useful lives, which range from three to fifteen years.

Impairment of oil and natural gas properties. This is the cost to reduce proved oil and gas properties to the calculated full cost ceiling value.

Other income (expense)

Interest income (expense). We have financed a portion of our working capital requirements, capital expenditures and acquisitions with borrowings
under our revolving credit facility and our net proceeds from the issuance of the senior notes. We incur interest expense that is affected by both fluctuations in
interest  rates  and  our  financing  decisions.  This  amount  reflects  interest  paid  to  our  lender  plus  the  amortization  of  deferred  financing  costs  (including
origination and amendment fees), commitment fees and annual agency fees net of interest received on our cash and cash equivalents.

Gain (loss) on derivative instruments, net. We utilize commodity derivative financial instruments to reduce our exposure to fluctuations in the price
of crude oil. This amount represents (i) the recognition of the change in the fair value of open non-hedge derivative contracts as commodity prices change and
commodity derivative contracts expire or new ones are entered into, and (ii) our gains and losses on the settlement of these commodity derivative instruments.

Deferred tax assets (liabilities). We use the asset and liability method of accounting for income taxes, under which deferred tax assets and liabilities
are recognized for the future tax consequences of (1) temporary differences between the financial statement carrying amounts and the tax bases of existing
assets and liabilities and (2) operating loss and tax credit carryforwards. Deferred income tax assets and liabilities are based on enacted tax rates applicable to
the  future  period  when  those  temporary  differences  are  expected  to  be  recovered  or  settled.  The  effect  of  a  change  in  tax  rates  on  deferred  tax  assets  and
liabilities is recognized in income in the period the rate change is enacted. A valuation allowance is provided for deferred tax assets when it is more likely
than not the deferred tax assets will not be realized.

Comparison of the Years Ended December 31, 2019 and 2018

Oil, Natural Gas Liquids and Natural Gas Revenues. Our oil, natural gas liquids and natural gas revenues increased by approximately $1.8 billion,
or 82%, to $3.9 billion for the year ended December 31, 2019 from $2.1 billion for the year ended December 31, 2018. Our revenues are a function of oil,
natural gas liquids and natural gas production volumes sold and average sales prices received for those volumes. Average daily production sold increased by
152,533 BOE/d to 282,972  BOE/d  during  the  year  ended  December  31,  2019  from  130,439  BOE/d  during  the  year  ended  December  31,  2018.  The  total
increase in revenue of approximately $1.8 billion is attributable to higher oil, natural gas liquids and natural gas production volumes, partially offset by lower
average sales prices for the year ended December 31, 2019 as compared to the year ended December 31, 2018. The increase in production volumes were due
to a combination of increased drilling activity and growth through acquisitions. Our

production increased by 34,151 MBbls of oil, 62,944 MMcf of natural gas and 11,033 MBbls of natural gas liquids for the year ended December 31, 2019 as
compared to the year ended December 31, 2018.

The net dollar effect of the change in prices of approximately $501 million (calculated as the change in period-to-period average prices multiplied by
current  period  production  volumes  of  oil,  natural  gas  liquids  and  natural  gas)  and  the  net  dollar  effect  of  the  change  in  production  of  approximately  $2.3

In general, production taxes and ad valorem taxes are directly related to commodity price changes; however, Texas ad valorem taxes are based upon
prior year commodity prices, among other factors, whereas production taxes are based upon current year commodity prices. Production taxes for the year
ended December 31, 2019 as compared to the year ended December 31, 2018 increased by $80 million due to increased overall production from acquisitions
and well completions. Production taxes per BOE for the year ended December 31, 2019 as compared to the year  ended  December  31,  2018 decreased  by
$0.40 primarily due to a higher percentage increase in production volumes as compared to production taxes. Ad valorem taxes for the year ended December
31, 2019 as compared to the year ended December 31, 2018 increased by $35 million due to the addition of acquired and completed wells from the latter half
of 2019.

We  are  required  to  recognize  all  derivative  instruments  on  the  balance  sheet  as  either  assets  or  liabilities  measured  at  fair  value.  We  have  not
designated our derivative instruments as hedges for accounting purposes. As a result, we mark our derivative instruments to fair value and recognize the cash

The change in our income tax provision was primarily due to the decrease in pre-tax income for the year ended December 31, 2019 and the change in
the deferred income tax benefit resulting from estimated deferred taxes recognized as a result of Viper’s change in tax status for the years ended December 31,
2019 and 2018.

Liquidity and Capital Resources

Historically, our primary sources of liquidity have been proceeds from our public equity offerings, borrowings under our revolving credit facility,
proceeds from the issuance of the senior notes and cash flows from operations. Our primary use of capital has been for the acquisition, development and
exploration of oil and natural gas properties. As we pursue reserves and production growth, we regularly consider which capital resources, including equity
and debt financings, are available to meet our future financial obligations, planned capital expenditure activities and liquidity requirements. Our future ability
to grow proved reserves and production will be highly dependent on the capital resources available to us.

Liquidity and Cash Flow

Our cash flows for the years ended December 31, 2019 and 2018 are presented below:

Net cash provided by operating activities was $2.7 billion for the year ended December 31, 2019  as  compared  to  $1.6 billion  for  the  year ended
December  31,  2018.  The  increase  in  operating  cash  flows  is  primarily  the  result  of  an  increase  in  our  oil  and  natural  gas  revenues  due  to  an  increase  in
production during the year ended December 31, 2019, partially offset by lower average sales prices.

Our operating cash flow is sensitive to many variables, the most significant of which is the volatility of prices for the oil and natural gas we produce.

Prices for these commodities are determined primarily by prevailing market conditions. Regional

68

and worldwide economic activity, weather and other substantially variable factors influence market conditions for these products. These factors are beyond
our control and are difficult to predict. See “–Sources of our revenue” and Item 1A. “Risk Factors” above.

Investing Activities

The purchase and development of oil and natural gas properties accounted for the majority of our cash outlays for investing activities. We used cash

for investing activities of $3.9 billion and $3.5 billion during the years ended December 31, 2019 and 2018, respectively.

During the year ended December 31, 2019, we spent (a) $2.7 billion on capital expenditures in conjunction with our drilling program, in which we
drilled 330 gross (296 net) horizontal wells and completed 317 gross (289 net) operated horizontal wells, (b) $244 million on additions to midstream assets,
(c) $333 million  for  the  acquisition  of  mineral  interests,  (d)  $443 million  on  leasehold  acquisitions,  (e)  $5 million  for  the  purchase  of  other  property  and
equipment, (f) $1 million on investment in real estate and (g) $485 million on equity method investments.

During the year ended December 31, 2018, we spent (a) $1.5 billion on capital expenditures in conjunction with our drilling program, in which we
drilled 189 gross (168 net) horizontal wells and completed 176 gross (155 net) operated horizontal wells, (b) $204 million on additions to midstream assets,
(c)  $440  million  for  the  acquisition  of  mineral  interests,  (d)  $1.4  billion  on  leasehold  acquisitions,  (e)  $7  million  for  the  purchase  of  other  property  and
equipment and (f) $111 million on investment in real estate.

4.750% Senior Notes

On October 28, 2016, we issued $500.0 million in aggregate principal amount of 4.750% senior notes due 2024 under an indenture among us, the
subsidiary  guarantors  party  thereto  and  Wells  Fargo,  as  the  trustee.  On  September  25,  2018,  we  issued  $750 million  aggregate  principal  amount  of  new
4.750% senior notes as additional notes under, and subject to the terms of the same indenture governing the 4.750% senior notes. We received approximately
$741 million in net proceeds, after deducting the initial purchasers’ discount and our estimated offering expenses, but disregarding accrued interest, from the
issuance of the 4.750% senior notes. We used a portion of the net proceeds from the issuance of the 4.750% senior notes to repay a portion of the outstanding
borrowings  our  revolving  credit  facility  and  the  balance  for  general  corporate  purposes,  including  funding  a  portion  of  the  cash  consideration  for  the
acquisition of certain assets from Ajax Resources LLC.

On  December  20,  2019,  we  redeemed  all  of  the  outstanding  4.750%  senior  notes,  which  we  refer  to  as  the  Redemption  Date.  The  redemption
payment,  which  we  refer  to  the  Redemption  Payment,  included  $1.25 billion  of  outstanding  principal  at  a  redemption  price  of  103.563% of the principal
amount of the 4.750% senior notes, plus accrued and unpaid interest on the outstanding principal amount to the Redemption Date. On December 5, 2019, the
indenture governing the 4.750% senior notes was fully satisfied and discharged and the guarantors were released from their guarantees of the 4.750% senior
notes.  The  4.750%  senior  notes,  which  bore  interest  at  4.750%  per  year,  were  scheduled  to  mature  on  November  1,  2024.  On  the  Redemption  Date,  the
Redemption Price will be paid to the holders of the 4.750% senior notes. We funded the Redemption Payment with a portion of our net proceeds from the
issuance of the December 2019 Notes.

The 4.750% senior notes, bore interest at a rate of 4.750% per annum, payable semi-annually, in arrears on May 1 and November 1 of each year,
commencing on May 1, 2017, and would have matured on November 1, 2024. All of our restricted subsidiaries that guaranteed our revolving credit facility
guaranteed  the  4.750%  senior  notes;  provided,  however,  that  the  4.750%  senior  notes  were  not  guaranteed  by  Viper,  Viper’s  General  Partner,  Viper  LLC,
Rattler, Rattler’s General Partner or Rattler LLC.

2025 Senior Notes

On December 20, 2016, we issued $500.0 million in aggregate principal amount of 5.375% senior notes due 2025, which we refer to as the exiting
2025 notes, under an indenture among us, the subsidiary guarantors party thereto and Wells Fargo, as the trustee, which we refer to as the 2025 indenture. On
January 29, 2018, we issued $300.0 million aggregate principal amount of new 5.375% senior notes due 2025 as additional notes under the 2025 indenture,
which we refer to as the new 2025 notes and, together with the existing 2025 notes, as the 2025 senior notes. We received approximately $308.4 million in net
proceeds, after deducting the initial purchaser’s discount and our estimated offering expenses, but disregarding accrued interest, from the issuance of the new
2025 notes. We used the net proceeds from the issuance of the new 2025 notes to repay a portion of the outstanding borrowings under our revolving credit
facility.

The 2025 senior notes bear interest at a rate of 5.375% per annum, payable semi-annually, in arrears on May 31 and November 30 of each year and
will mature on May 31, 2025. All of our existing and future restricted subsidiaries that guarantee our revolving credit facility guarantee the 2025 senior notes.
Currently, the 2025 senior notes are not guaranteed by any of our subsidiaries other than Diamondback O&G LLC and will not be guaranteed by any of our
future unrestricted subsidiaries.

elsewhere in this Form 10-K.

December 2019 Notes Offering

On December 5, 2019, we issued $1.0 billion in aggregate principal amount of 2.875% senior notes due 2024, $800 million in aggregate principal
amount  of  3.250%  senior  notes  due  2026  and  $1.2  billion  aggregate  principal  amount  of  3.500%  senior  notes  due  2029.  The  2024  notes  will  mature  on
December 1, 2024, the 2026 notes will mature on December 1, 2026 and the 2029 notes will mature on December 1, 2029. Interest will accrue and be payable
semi-annually, in arrears on June 1 and December 1 of each year, commencing on June 1, 2020. The December 2019 notes are fully and unconditionally
guaranteed by Diamondback O&G LLC and are not guaranteed by any of our other subsidiaries.

The  December  2019  notes  were  issued  under  an  indenture,  dated  as  of  December  5,  2019,  among  us  and  Wells  Fargo  Bank,  as  the  trustee,  as
supplemented by the first supplemental indenture dated as of December 5, 2019, which we refer to as the December 2019 Notes Indenture. The December
2019 Notes Indenture contains certain covenants that, subject to certain exceptions and qualifications, among other things, limit our ability and the ability of
certain of our subsidiaries to incur liens

securing funded indebtedness and on our ability to consolidate, merge or sell, convey, transfer or lease all or substantially all of our assets.

Second Amended and Restated Credit Facility

We  and  Diamondback  O&G  LLC,  as  borrower,  entered  into  the  second  amended  and  restated  credit  agreement,  dated  November  1,  2013,  as
amended, with a syndicate of banks, including Wells Fargo, as administrative agent, and its affiliate Wells Fargo Securities, LLC, as sole book runner and lead
arranger. On June 28, 2019, the credit agreement was amended pursuant to an eleventh amendment, which implemented certain changes to the credit facility
for the period on and after the date on which our unsecured debt achieves an investment grade rating from two rating agencies and certain other conditions in
the credit agreement are satisfied (the “investment grade changeover date”). At December 31, 2019, the maximum credit amount available under the credit
agreement is $2.0 billion. As of December 31, 2019, we had approximately $13 million  of  outstanding  borrowings  under  our  revolving  credit  facility  and
$1.99 billion available for future borrowings under our revolving credit facility.

Diamondback  O&G  LLC  is  the  borrower  under  the  credit  agreement,  and  as  of  December  31,  2019,  the  credit  agreement  is  guaranteed  by
Diamondback Energy, Inc. None of our other subsidiaries are guarantors under our revolving credit facility. On December 5, 2019, Diamondback O&G LLC
delivered a letter notifying the administrative agent under the credit agreement that as of such date, each of the guarantors, other than Diamondback Energy,
Inc., ceased to be a guarantor under the credit agreement.

The outstanding borrowings under the credit agreement bear interest at a per annum rate elected by us that is equal to an alternate base rate (which is
equal to the greatest of the prime rate, the Federal Funds effective rate plus 0.50% and 3-month LIBOR plus 1.0%) or LIBOR, in each case plus the applicable
margin. The applicable margin ranges from 0.125% to 1.0% per annum and from 1.125% to 2.0% per annum in the case of LIBOR, in each case, depending
on the pricing level, which in turn depends on the rating agencies’ rating of our unsecured debt. We are obligated to pay a quarterly commitment fee ranging
from 0.125% to 0.350% per year on the unused portion of the commitment, based on the pricing level, which in turn depends on the rating agencies’ rating of
our unsecured debt.

Loan principal may be optionally prepaid from time to time without premium or penalty (other than customary LIBOR breakage). Loan principal is
required to be repaid (a) to the extent the loan amount exceeds the commitment due to any termination or reduction of the aggregate maximum credit amount
and (b) at the maturity date of November 1, 2022.

The  credit  agreement  contains  a  financial  covenant  that  requires  us  to  maintain  a  total  net  debt  to  capitalization  ratio  (as  defined  in  the  credit
agreement) of no more than 65%. Our non-guarantor restricted subsidiaries may incur debt for borrowed money in an aggregate principal amount up to 15%
of consolidated net tangible assets (as defined in the credit agreement) and we and our restricted subsidiaries may incur liens if the aggregate amount of debt
secured by such liens does not exceed 15% of consolidated net tangible assets.

As of December 31, 2019, we were in compliance with all financial covenants under our revolving credit facility, as then in effect. The lenders may
accelerate  all  of  the  indebtedness  under  our  revolving  credit  facility  upon  the  occurrence  and  during  the  continuance  of  any  event  of  default.  The  credit
agreement contains customary events of default, including non-payment, breach of covenants, materially incorrect representations, cross-default, bankruptcy
and change of control.

Energen Notes

At the effective time of the merger, Energen became our wholly owned subsidiary and remained the issuer of an aggregate principal amount of $530
million in notes, which we refer to as the Energen Notes, issued under an indenture dated September 1, 1996 with The Bank of New York as Trustee, which
we refer to as the Energen Indenture. As of December 31, 2019, the Energen Notes consist of: (a) $399 million aggregate principal amount of 4.625% senior
notes due on September 1, 2021, (2) $108 million of 7.125% notes due on February 15, 2028, (3) $21 million of 7.32% notes due on July 28, 2022, and (4)
$11 million of 7.35% notes due on July 28, 2027.

The Energen Notes are the senior unsecured obligations of Energen and, post-merger, Energen, as our wholly owned subsidiary, continues to be the
sole issuer and obligor under the Energen Notes. The Energen Notes rank equally in right of payment with all other senior unsecured indebtedness of Energen
if any, and are effectively subordinated to Energen’s senior secured indebtedness, if any, to the extent of the value of the collateral securing such indebtedness.
Neither we nor any of our subsidiaries guarantee the Energen Notes.

Viper’s Facility-Wells Fargo Bank

On  July  20,  2018,  Viper  LLC,  as  borrower,  entered  into  an  amended  and  restated  credit  agreement  with  Viper,  as  guarantor,  Wells  Fargo,  as
administrative agent, and the other lenders. The credit agreement, as amended, which we refer to as the Viper credit agreement, provides for a revolving credit
facility in the maximum credit amount of $2 billion and a borrowing base based on Viper LLC’s oil and natural gas reserves and other factors (the “borrowing
base”)  of  $775 million,  subject  to  scheduled  semi-annual  and  other  elective  borrowing  base  redeterminations.  The  borrowing  base  is  scheduled  to  be  re-
determined semi-annually with effective dates of May 1st and November 1st. In addition, Viper LLC and Wells Fargo each may request up to three interim
redeterminations of the borrowing base during any 12-month period. In connection with Viper’s fall redetermination in November 2019, the borrowing base
under the Viper credit agreement was increased to $775 million. As of December 31, 2019, the borrowing base was $775 million, and Viper LLC had $97
million  of  outstanding  borrowings  and  $678  million  available  for  future  borrowings  under  the  Viper  credit  agreement.  Neither  we  nor  any  of  our  other
subsidiaries guarantee the Viper credit agreement.

The outstanding borrowings under the Viper credit agreement bear interest at a per annum rate elected by Viper LLC that is equal to an alternate base
rate (which is equal to the greatest of the prime rate, the Federal Funds effective rate plus 0.5% and 3-month LIBOR plus 1.0%) or LIBOR, in each case plus
the applicable margin. The applicable margin ranges from 0.75% to 1.75% per annum in the case of the alternate base rate and from 1.75% to 2.75%  per
annum in the case of LIBOR, in each case depending on the amount of loans and letters of credit outstanding in relation to the commitment, which is defined
as  the  lesser  of  the  maximum  credit  amount  and  the  borrowing  base.  Viper  LLC  is  obligated  to  pay  a  quarterly  commitment  fee  ranging  from  0.375% to
0.500% per year on the unused portion of the commitment, which fee is also dependent on the amount of loans and letters of credit outstanding in relation to
the commitment. Loan principal may be optionally prepaid from time to time without premium or penalty (other than customary LIBOR breakage), and is
required to be repaid (i) to the extent the loan amount exceeds the commitment or the borrowing base, whether due to a borrowing base redetermination or
otherwise  (in  some  cases  subject  to  a  cure  period),  (ii)  in  an  amount  equal  to  the  net  cash  proceeds  from  the  sale  of  property  when  a  borrowing  base
deficiency or event of default exists under the credit agreement and (iii) at the maturity date of November 1, 2022. The loan is secured by substantially all of
the assets of Viper and Viper LLC.

The Viper credit agreement contains various affirmative, negative and financial maintenance covenants. These covenants, among other things, limit
additional indebtedness, purchases of margin stock, additional liens, sales of assets, mergers and consolidations, dividends and distributions, transactions with
affiliates and entering into certain swap agreements and require the maintenance of the financial ratios described below.

Financial Covenant

Ratio of total net debt to EBITDAX, as defined in the Viper credit agreement

Ratio of current assets to liabilities, as defined in the Viper credit agreement

Required Ratio

Not greater than 4.0 to 1.0

Not less than 1.0 to 1.0

The covenant prohibiting additional indebtedness allows for the issuance of unsecured debt of up to $1.0 billion  in  the  form  of  senior  unsecured
notes  and,  in  connection  with  any  such  issuance,  the  reduction  of  the  borrowing  base  by  25%  of  the  stated  principal  amount  of  each  such  issuance.  The
covenant limiting dividends and distributions includes an exception allowing Viper LLC to make distributions if no default, event of default or borrowing
base deficiency exists.

As of December 31, 2019, Viper and Viper LLC were in compliance with all financial covenants under the Viper credit agreement, as then in effect.
The lenders may accelerate all of the indebtedness under the Viper credit agreement upon the occurrence and during the continuance of any event of default.
The Viper credit agreement contains customary events of default, including non-payment, breach of covenants, materially incorrect representations, cross-
default, bankruptcy and change of control.

Viper’s Notes

On  October  16,  2019,  Viper  completed  an  offering  in  which  it  issued  its  5.375%  Senior  Notes  due  2027  in  aggregate  principal  amount  of  $500
million. Viper received gross proceeds of $500 million from the such offering, which it loaned to Viper LLC. Viper LLC paid the expenses of the offering,
resulting in net proceeds of the offering of $490 million, which Viper LLC used to pay down borrowings under the Viper credit agreement.

72

Table of Contents

The Viper Notes were issued under an indenture, dated as of October 16, 2019, among Viper, as issuer, Viper LLC, as guarantor and Wells Fargo, as
trustee, which we refer to as the Viper Indenture. Pursuant to the Viper Indenture and the Viper Notes, interest on the Viper Notes accrues at a rate of 5.375%
per annum on the outstanding principal amount thereof, payable semi-annually on May 1 and November 1 of each year, commencing on May 1, 2020. The
Viper Notes will mature on November 1, 2027.

Viper LLC guarantees the Viper Notes pursuant to the Viper Indenture. Neither we nor any of our other subsidiaries guarantee the Viper Notes.

The Viper Indenture contains certain covenants that, subject to certain exceptions and qualifications, among other things, limit Viper’s ability and the
ability of its restricted subsidiaries to incur or guarantee additional indebtedness or issue certain redeemable or preferred equity, make certain investments,
declare or pay dividends or make distributions on equity interests or redeem, repurchase or retire equity interests or subordinated indebtedness, transfer or sell
assets, agree to payment restrictions affecting its restricted subsidiaries, consolidate, merge, sell or otherwise dispose of all or substantially all of its assets,
enter into transactions with affiliates, incur liens and designate certain of its subsidiaries as unrestricted subsidiaries. These covenants are subject to numerous
exceptions, some of which are material. Certain of these covenants are subject to termination upon the occurrence of certain events.

Rattler’s Credit Agreement

In connection with the Rattler Offering, Rattler, as parent, and Rattler LLC, as borrower, entered into a credit agreement, dated May 28, 2019, with

Wells Fargo Bank, as administrative agent, and a syndicate of banks, as lenders party thereto, which we refer to as the Rattler credit agreement.

The  Rattler  credit  agreement  provides  for  a  revolving  credit  facility  in  the  maximum  credit  amount  of  $600  million.  Loan  principal  may  be
optionally prepaid from time to time without premium or penalty (other than customary LIBOR breakage), and is required to be prepaid at the maturity date
of May 28, 2024. The Rattler credit agreement is guaranteed by Rattler, Tall City, Rattler OMOG LLC and Rattler Ajax Processing LLC and is secured by
substantially all of the assets of Rattler LLC, Rattler, Tall City, Rattler OMOG LLC and Rattler Ajax Processing LLC. As of December 31, 2019, Rattler LLC
had $424 million of outstanding borrowings and $176 million available for future borrowings under the Rattler credit agreement.

The outstanding borrowings under the Rattler credit agreement bear interest at a per annum rate elected by Rattler LLC that is based on the prime
rate or LIBOR, in each case plus an applicable margin. The applicable margin ranges from 0.250% to 1.250% per annum for prime-based loans and 1.250%
to 2.250% per annum for LIBOR loans, in each case depending on the Consolidated Total Leverage Ratio (as defined in the Rattler credit agreement). Rattler
LLC is obligated to pay a quarterly commitment fee ranging from 0.250% to 0.375% per annum on the unused portion of the commitment, which fee is also
dependent on the Consolidated Total Leverage Ratio.

The  Rattler  credit  agreement  contains  various  affirmative  and  negative  covenants.  These  covenants,  among  other  things,  limit  additional
indebtedness, additional liens, sales of assets, mergers and consolidations, distributions and other restricted payments, transactions with affiliates, and entering
into certain swap agreements, in each case of Rattler, Rattler LLC and their restricted subsidiaries. The covenants are subject to exceptions set forth in the
Rattler credit agreement, including an exception allowing Rattler LLC or Rattler to issue unsecured debt securities and an exception allowing payment of
distributions if no default or events of default exists.

73

Table of Contents

The Rattler credit agreement also contains financial maintenance covenants that require the maintenance of the financial ratios described below:

Financial Covenant

Consolidated Total Leverage Ratio

Required Ratio

Not greater than 5.00 to 1.00 (or not greater than 5.50
to 1.00 for 3 fiscal quarters following certain
acquisitions), but if the Consolidated Senior Secured
Leverage Ratio (as defined in the Rattler credit
agreement) is applicable, then not greater than 5.25 to
1.00)

Consolidated Senior Secured Leverage Ratio commencing with the last day of any fiscal quarter in
which the Financial Covenant Election (as defined in the Rattler credit agreement) is made

Consolidated Interest Coverage Ratio (as defined in the Rattler credit agreement)

Not greater than 3.50 to 1.00

Not less than 2.50 to 1.00

For purposes of calculating the financial maintenance covenants prior to the fiscal quarter ending June 30, 2020, EBITDA (as defined in the Rattler
credit agreement) will be annualized based on the actual EBITDA for the preceding fiscal quarters starting with the fiscal quarter ending September 30, 2019.

As of December 31, 2019, Rattler and Rattler LLC were in compliance with all financial covenants under the Rattler credit agreement. The lenders
may accelerate all of the indebtedness under the Rattler credit agreement upon the occurrence and during the continuance of any event of default. The Rattler
credit  agreement  contains  customary  events  of  default,  including  non-payment,  breach  of  covenants,  materially  incorrect  representations,  cross-default,
bankruptcy and change in control.

Capital Requirements and Sources of Liquidity

Our  board  of  directors  approved  a  2020  capital  budget  for  drilling,  midstream  and  infrastructure  of  $2.8 billion  to  $3.0  billion,  representing  an

increase of 1% over our 2019 capital budget. We estimate that, of these expenditures, approximately:

•

•

•

$2.45 billion to $2.6 billion will be spent on drilling and completing 320 to 360 gross (288 to 324 net) horizontal wells across our operated leasehold
acreage in the Northern Midland and Southern Delaware Basins, with an average lateral length of approximately 9,700 feet;

$200 million to $225 million will be spent on midstream infrastructure, excluding joint venture investments; and

$150  million  to  $175  million  will  be  spent  on  infrastructure  and  other  expenditures,  excluding  the  cost  of  any  leasehold  and  mineral  interest
acquisitions.

During the year ended December 31, 2019, our aggregate capital expenditures for drilling and infrastructure were $2.7 billion.  We  do  not  have  a
specific acquisition budget since the timing and size of acquisitions cannot be accurately forecasted. During the year ended December 31, 2019,  we  spent
approximately $443 million in cash on acquisitions of leasehold interests and mineral acres.

In  May  2019,  our  board  of  directors  approved  a  stock  repurchase  program  to  acquire  up  to  $2  billion  of  our  outstanding  common  stock  through
December 31, 2020. We repurchased approximately $598 million of our common stock under this program during the year ended December 31, 2019, with
approximately $1.4 billion  remaining  available  for  future  repurchases  under  this  program.  We  intend  to  continue  to  purchase  shares  under  the  repurchase
program opportunistically with available funds primarily from cash flow from operations and liquidity events such as the sale of assets while maintaining
sufficient liquidity to fund our capital expenditure programs.

The  amount  and  timing  of  our  capital  expenditures  are  largely  discretionary  and  within  our  control.  We  could  choose  to  defer  a  portion  of  these
planned capital expenditures depending on a variety of factors, including but not limited to the success of our drilling activities, prevailing and anticipated
prices for oil and natural gas, the availability of necessary equipment, infrastructure and capital, the receipt and timing of required regulatory permits and
approvals, seasonal conditions, drilling and acquisition costs and the level of participation by other interest owners. We are currently operating 23 drilling rigs
including  two  rigs  drilling  produced  water  disposal  wells  and  nine  completion  crews.  We  will  continue  monitoring  commodity  prices  and  overall  market
conditions and can adjust our rig cadence up or down in response to changes in commodity prices and overall market conditions.

74

 
Table of Contents

Based upon current oil and natural gas prices and production expectations for 2020, we believe that our cash flow from operations, cash on hand and
borrowings under our revolving credit facility will be sufficient to fund our operations through year-end 2020. However, future cash flows are subject to a
number of variables, including the level of oil and natural gas production and prices, and significant additional capital expenditures will be required to more
fully develop our properties. Further, our 2020 capital expenditure budget does not allocate any funds for leasehold interest and property acquisitions.

We  monitor  and  adjust  our  projected  capital  expenditures  in  response  to  the  results  of  our  drilling  activities,  changes  in  prices,  availability  of
financing,  drilling  and  acquisition  costs,  industry  conditions,  the  timing  of  regulatory  approvals,  the  availability  of  rigs,  contractual  obligations,  internally
generated  cash  flow  and  other  factors  both  within  and  outside  our  control.  If  we  require  additional  capital,  we  may  seek  such  capital  through  traditional
reserve base borrowings, joint venture partnerships, production payment financing, asset sales, offerings of debt and or equity securities or other means. We
cannot assure you that the needed capital will be available on acceptable terms or at all. If we are unable to obtain funds when needed or on acceptable terms,
we may be required to curtail our drilling programs, which could result in a loss of acreage through lease expirations. In addition, we may not be able to
complete acquisitions that may be favorable to us or finance the capital expenditures necessary to replace our reserves. If there is a decline in commodity
prices, our revenues, cash flows, results of operations, liquidity and reserves may be materially and adversely affected.

this floating rate facility as we cannot predict the timing of future borrowings and repayments or interest rates to be charged.

(2) Includes only the minimum amount of commitment fees due which, as of December 31, 2019, includes a commitment fee equal to 0.125% per year of

the unused portion of the borrowing base of the Company’s credit agreement.

(3) Interest represents the scheduled cash payments on the senior notes and Energen Notes.
(4) Includes only the minimum amount of commitment fees due which, as of December 31, 2019, includes a commitment fee equal to 0.375% per year of

the unused portion of the borrowing base of Viper’s credit agreement.

(5) Includes only the minimum amount of commitment fees due which, as of December 31, 2019, includes a commitment fee equal to 0.250% per year of

the unused portion of the borrowing base of Rattler’s credit agreement.

(6) Amounts represent our estimates of future asset retirement obligations. Because these costs typically extend many years into the future, estimating these
future costs requires management to make estimates and judgments that are subject to future revisions based upon numerous factors, including the rate
of  inflation,  changing  technology  and  the  political  and  regulatory  environment.  See  Note  8—Asset  Retirement  Obligations  of  the  Notes  to  the

The table above does not include estimated deficiency fees related to certain volume commitments that we have as they are based off future volume

deliveries and differences from market pricing which we cannot predict.

Critical Accounting Policies

The discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have
been prepared in accordance with accounting principles generally accepted in the United States. Below, we have provided expanded discussion of our more
significant accounting policies, estimates and judgments. We believe these accounting policies reflect our more significant estimates and assumptions used in
preparation  of  our  financial  statements.  See  Note  2—Summary  of  Significant  Accounting  Policies  of  the  Notes  to  the  Consolidated  Financial  Statements
included elsewhere in this Form 10-K.

Use of Estimates

Certain  amounts  included  in  or  affecting  our  consolidated  financial  statements  and  related  disclosures  must  be  estimated  by  our  management,
requiring  certain  assumptions  to  be  made  with  respect  to  values  or  conditions  that  cannot  be  known  with  certainty  at  the  time  the  consolidated  financial
statements are prepared. These estimates and assumptions affect the amounts we report for assets and liabilities and our disclosure of contingent assets and
liabilities at the date of the consolidated financial statements. Actual results could differ from those estimates.

We evaluate these estimates on an ongoing basis, using historical experience, consultation with experts and other methods we consider reasonable in
the particular circumstances. Nevertheless, actual results may differ significantly from our estimates. Any effects on our business, financial position or results
of operations resulting from revisions to these estimates are recorded in the period in which the facts that give rise to the revision become known. Significant
items subject to such estimates and assumptions include estimates of proved oil and gas reserves and related present value estimates of future net cash flows
therefrom,  the  carrying  value  of  oil  and  natural  gas  properties,  asset  retirement  obligations,  the  fair  value  determination  of  acquired  assets  and  liabilities,
equity-based compensation, fair value estimates of commodity derivatives and estimates of income taxes.

Method of accounting for oil and natural gas properties

We  account  for  our  oil  and  natural  gas  producing  activities  using  the  full  cost  method  of  accounting.  Accordingly,  all  costs  incurred  in  the
acquisition, exploration and development of proved oil and natural gas properties, including the costs of abandoned properties, dry holes, geophysical costs
and annual lease rentals are capitalized. We also capitalize direct operating costs for services performed with internally owned drilling and well servicing
equipment. Internal costs capitalized to the full cost pool represent management’s estimate of costs incurred directly related to exploration and development
activities such as geological and other administrative costs associated with overseeing the exploration and development activities. All internal costs unrelated
to drilling activities are expensed as incurred. Sales or other dispositions of oil and natural gas properties are accounted for as adjustments to capitalized costs,
with  no  gain  or  loss  recorded  unless  the  ratio  of  cost  to  proved  reserves  would  significantly  change.  Income  from  services  provided  to  working  interest
owners of properties in which we also own an interest, to the extent they exceed related costs incurred, are accounted for as reductions of capitalized costs of
oil and natural gas properties. Depletion of evaluated oil and natural gas properties is computed on the units of production method, whereby capitalized costs
plus estimated future development costs are amortized over total proved reserves.

Costs associated with unevaluated properties are excluded from the full cost pool until we have made a determination as to the existence of proved
reserves. We assess all items classified as unevaluated property on an annual basis for possible impairment. We assess properties on an individual basis or as a
group if properties are individually insignificant. The assessment includes consideration of the following factors, among others: intent to drill; remaining lease
term; geological and geophysical evaluations; drilling results and activity; the assignment of proved reserves; and the economic viability of development if
proved reserves are assigned. During any period in which these factors indicate an impairment, the cumulative drilling costs incurred to date for such property
and all or a portion of the associated leasehold costs are transferred to the full cost pool and are then subject to amortization.

Table of Contents

Oil and natural gas reserve quantities and standardized measure of future net revenue

Our independent engineers and technical staff prepare our estimates of oil and natural gas reserves and associated future net revenues. The SEC has
defined proved reserves as the estimated quantities of oil and natural gas which geological and engineering data demonstrate with reasonable certainty to be
recoverable in future years from known reservoirs under existing economic and operating conditions. The process of estimating oil and natural gas reserves is
complex, requiring significant decisions in the evaluation of available geological, geophysical, engineering and economic data. The data for a given property
may  also  change  substantially  over  time  as  a  result  of  numerous  factors,  including  additional  development  activity,  evolving  production  history  and  a
continual reassessment of the viability of production under changing economic conditions. As a result, material revisions to existing reserve estimates occur
from time to time. Although every reasonable effort is made to ensure that reserve estimates reported represent the most accurate assessments possible, the
subjective decisions and variances in available data for various properties increase the likelihood of significant changes in these estimates. If such changes are
material, they could significantly affect future amortization of capitalized costs and result in impairment of assets that may be material.

There are numerous uncertainties inherent in estimating quantities of proved oil and natural gas reserves. Oil and natural gas reserve engineering is a
subjective process of estimating underground accumulations of oil and natural gas that cannot be precisely measured and the accuracy of any reserve estimate
is  a  function  of  the  quality  of  available  data  and  of  engineering  and  geological  interpretation  and  judgment.  Results  of  drilling,  testing  and  production
subsequent to the date of the estimate may justify revision of such estimate. Accordingly, reserve estimates are often different from the quantities of oil and
natural gas that are ultimately recovered.

Revenue recognition

Revenue from Contracts with Customers

Sales of oil, natural gas and natural gas liquids are recognized at the point control of the product is transferred to the customer. Virtually all of the
pricing provisions in our contracts are tied to a market index, with certain adjustments based on, among other factors, whether a well delivers to a gathering or
transmission line, the quality of the oil or natural gas and the prevailing supply and demand conditions. As a result, the price of the oil, natural gas and natural
gas liquids fluctuates to remain competitive with other available oil, natural gas and natural gas liquids supplies.

Oil sales

Our  oil  sales  contracts  are  generally  structured  where  it  delivers  oil  to  the  purchaser  at  a  contractually  agreed-upon  delivery  point  at  which  the
purchaser  takes  custody,  title  and  risk  of  loss  of  the  product.  Under  this  arrangement,  we  or  a  third  party  transports  the  product  to  the  delivery  point  and
receives a specified index price from the purchaser with no deduction. In this scenario, we recognize revenue when control transfers to the purchaser at the
delivery  point  based  on  the  price  received  from  the  purchaser.  Oil  revenues  are  recorded  net  of  any  third-party  transportation  fees  and  other  applicable
differentials in our consolidated statements of operations.

Natural gas and natural gas liquids sales

Under our natural gas processing contracts, it delivers natural gas to a midstream processing entity at the wellhead, battery facilities or the inlet of
the midstream processing entity’s system. The midstream processing entity gathers and processes the natural gas and remits proceeds to us for the resulting
sales of natural gas liquids and residue gas. In these scenarios, we evaluate whether it is the principal or the agent in the transaction. For those contracts where
we  have  concluded  it  is  the  principal  and  the  ultimate  third  party  is  its  customer,  we  recognize  revenue  on  a  gross  basis,  with  transportation,  gathering,
processing, treating and compression fees presented as an expense in our consolidated statements of operations.

In certain natural gas processing agreements, we may elect to take its residue gas and/or natural gas liquids in-kind at the tailgate of the midstream
entity’s processing plant and subsequently market the product. Through the marketing process, we deliver product to the ultimate third-party purchaser at a
contractually  agreed-upon  delivery  point  and  receives  a  specified  index  price  from  the  purchaser.  In  this  scenario,  we  recognize  revenue  when  control
transfers to the purchaser at the delivery point based on the index price received from the purchaser. The gathering, processing, treating and compression fees
attributable to the gas processing contract, as well as any transportation fees incurred to deliver the product to the purchaser, are presented as transportation,
gathering, processing, treating and compression expense in our consolidated statements of operations.

Table of Contents

Midstream Revenue

Substantially all revenues from gathering, compression, water handling, disposal and treatment operations are derived from intersegment transactions
for  services  Rattler  provides  to  exploration  and  production  operations.  The  portion  of  such  fees  shown  in  our  consolidated  financial  statements  represent
amounts charged to interest owners in our operated wells, as well as fees charged to other third parties for water handling and treatment services provided by
Rattler  or  usage  of  Rattler’s  gathering  and  compression  systems.  For  gathering  and  compression  revenue,  Rattler  satisfies  its  performance  obligations  and
recognizes revenue when low pressure volumes are delivered to a specified delivery point. Revenue is recognized based on the per MMbtu gathering fee or a
per barrel gathering fee charged by Rattler in accordance with the gathering and compression agreement. For water handling and treatment revenue, Rattler
satisfies its performance obligations and recognizes revenue when the water volumes have been delivered to the fracwater meter for a specified well pad and
the  wastewater  volumes  have  been  metered  downstream  of  our  facilities.  For  services  contracted  through  third  party  providers,  Rattler’s  performance
obligation  is  satisfied  when  the  service  performed  by  the  third  party  provider  has  been  completed.  Revenue  is  recognized  based  on  the  per  barrel  water
delivery or a wastewater gathering and disposal fee charged by Rattler in accordance with the water services agreement.

Transaction price allocated to remaining performance obligations

Our  upstream  product  sales  contracts  do  not  originate  until  production  occurs  and,  therefore,  are  not  considered  to  exist  beyond  each  days’

production. Therefore, there are no remaining performance obligations under any of our product sales contracts.

The majority of our midstream revenue agreements have a term greater than one year, and as such we have utilized the practical expedient in ASC
606,  which  states  that  we  are  not  required  to  disclose  the  transaction  price  allocated  to  remaining  performance  obligations  if  the  variable  consideration  is
allocated entirely to a wholly unsatisfied performance obligation. Under our revenue agreements, each delivery generally represents a separate performance
obligation; therefore, future volumes delivered are wholly unsatisfied and disclosure of the transaction price allocated to remaining performance obligations is
not required.

The remainder of our midstream revenue agreements, which relate to agreements with third parties, are short-term in nature with a term of one year
or  less.  We  have  utilized  an  additional  practical  expedient  in  ASC  606  which  exempts  it  from  disclosure  of  the  transaction  price  allocated  to  remaining
performance obligations if the performance obligation is part of an agreement that has an original expected duration of one year or less.

Contract balances

Under our product sales contracts, we have the right to invoice our customers once the performance obligations have been satisfied, at which point

payment is unconditional. Accordingly, our product sales contracts do not give rise to contract assets or liabilities under ASC 606.

Prior-period performance obligations

We  record  revenue  in  the  month  production  is  delivered  to  the  purchaser.  However,  settlement  statements  for  certain  natural  gas  and  natural  gas
liquids sales may not be received for 30 to 90 days after the date production is delivered, and as a result, we are required to estimate the amount of production
delivered  to  the  purchaser  and  the  price  that  will  be  received  for  the  sale  of  the  product.  We  record  the  differences  between  our  estimates  and  the  actual
amounts received for product sales in the month that payment is received from the purchaser. We have existing internal controls for our revenue estimation
process and related accruals, and any identified differences between our revenue estimates and actual revenue received historically have not been significant.
For the year ended December 31, 2019, revenue recognized in the reporting period related to performance obligations satisfied in prior reporting periods was
not material. We believe that the pricing provisions of our oil, natural gas and natural gas liquids contracts are customary in the industry. To the extent actual
volumes and prices of oil and natural gas sales are unavailable for a given reporting period because of timing or information not received from third parties,
the revenue related to expected sales volumes and prices for those properties are estimated and recorded.

Impairment

We use the full cost method of accounting for our oil and natural gas properties. Under this method, all acquisition, exploration and development
costs, including certain internal costs, are capitalized and amortized on a composite unit of production method based on proved oil, natural gas liquids and
natural  gas  reserves.  Internal  costs  capitalized  to  the  full  cost  pool  represent  management’s  estimate  of  costs  incurred  directly  related  to  exploration  and
development activities such as geological and other administrative costs associated with overseeing the exploration and development activities. All internal
costs not directly associated with exploration and development activities were charged to expense as they were incurred. Costs associated with unevaluated
properties are excluded from the full cost pool until we have made a determination as to the existence

78

Table of Contents

of proved reserves. The inclusion of our unevaluated costs into the amortization base is expected to be completed within three to five years. Sales of oil and
natural gas properties, whether or not being amortized currently, are accounted for as adjustments of capitalized costs, with no gain or loss recognized, unless
such adjustments would significantly alter the relationship between capitalized costs and proved reserves of oil, natural gas liquids and natural gas.

Under this method of accounting, we are required to perform a ceiling test each quarter. The test determines a limit, or ceiling, on the book value of
the proved oil and natural gas properties. Net capitalized costs are limited to the lower of unamortized cost net of deferred income taxes, or the cost center
ceiling. The cost center ceiling is defined as the sum of (a) estimated future net revenues, discounted at 10% per annum, from proved reserves, based on the
trailing  12-month  unweighted  average  of  the  first-day-of-the-month  price,  adjusted  for  any  contract  provisions  and  excluding  the  estimated  abandonment
costs for properties with asset retirement obligations recorded on the balance sheet, (b) the cost of properties not being amortized, if any, and (c) the lower of
cost or market value of unproved properties included in the cost being amortized, including related deferred taxes for differences between the book and tax
basis of the oil and natural gas properties. If the net book value, including related deferred taxes, exceeds the ceiling, an impairment or non-cash writedown is
required.

Asset retirement obligations

We  measure  the  future  cost  to  retire  our  tangible  long-lived  assets  and  recognize  such  cost  as  a  liability  for  legal  obligations  associated  with  the
retirement of long-lived assets that result from the acquisition, construction or normal operation of a long-lived asset. The fair value of a liability for an asset’s
retirement  obligation  is  recorded  in  the  period  in  which  it  is  incurred  if  a  reasonable  estimate  of  fair  value  can  be  made  and  the  corresponding  cost  is
capitalized as part of the carrying amount of the related long-lived asset. The liability is accreted to its then present value each period, and the capitalized cost
is depreciated over the useful life of the related asset. If the liability is settled for an amount other than the recorded amount, the difference is recorded in oil
and natural gas properties.

Our  asset  retirement  obligations  primarily  relate  to  the  future  plugging  and  abandonment  of  wells  and  related  facilities.  Estimating  the  future
restoration and removal costs is difficult and requires management to make estimates and judgments because most of the removal obligations are many years
in  the  future  and  asset  removal  technologies  and  costs  are  constantly  changing,  as  are  regulatory,  political,  environmental,  safety  and  public  relations
considerations. We estimate the future plugging and abandonment costs of wells, the ultimate productive life of the properties, a risk-adjusted discount rate
and an inflation factor in order to determine the current present value of this obligation. To the extent future revisions to these assumptions impact the present
value of the existing asset retirement obligation liability, a corresponding adjustment is made to the oil and natural gas property balance.

Derivatives

From time to time, we have used energy derivatives for the purpose of mitigating the risk resulting from fluctuations in the market price of crude oil
and natural gas. We recognize all of our derivative instruments as either assets or liabilities at fair value. The accounting for changes in the fair value (i.e.,
gains or losses) of a derivative instrument depends on whether it has been designated and qualifies as part of a hedging relationship and further on the type of
hedging relationship. None of our derivatives were designated as hedging instruments during the years ended December 31, 2019 and 2018. For derivative
instruments not designated as hedging instruments, changes in the fair value of these instruments are recognized in earnings during the period of change.

Accounting for Equity-Based Compensation

We grant various types of equity-based awards including stock options and restricted stock units. These plans and related accounting policies are
defined and described more fully in Note 12—Equity-Based Compensation of the Notes to the Consolidated Financial Statements included elsewhere in the
Form  10-K.  Stock  compensation  awards  are  measured  at  fair  value  on  the  date  of  grant  and  are  expensed,  net  of  estimated  forfeitures,  over  the  required
service period.

Income Taxes

We use the asset and liability method of accounting for income taxes, under which deferred tax assets and liabilities are recognized for the future tax
consequences  of  (1)  temporary  differences  between  the  financial  statement  carrying  amounts  and  the  tax  bases  of  existing  assets  and  liabilities  and  (2)
operating loss and tax credit carryforwards. Deferred income tax assets and liabilities are based on enacted tax rates applicable to the future period when those
temporary differences are expected to be recovered or settled. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income
in the period the rate change is enacted. A valuation allowance is provided for deferred tax assets when it is more likely than not the deferred tax assets will
not be realized.

Inflation

Inflation in the United States has been relatively low in recent years and did not have a material impact on results of operations for the years ended
December 31, 2019 and 2018. Although the impact of inflation has been insignificant in recent years, it is still a factor in the United States economy and we
tend to experience inflationary pressure on the cost of oilfield services and equipment as increasing oil and gas prices increase drilling activity in our areas of
operations.

Off-balance Sheet Arrangements

We had no off-balance sheet arrangements as of December 31, 2019. Please read Note 18—Commitments and Contingencies included in Notes to
the Consolidated Financial Statements included elsewhere in this Form 10-K, for a discussion of our commitments and contingencies, some of which are not
recognized in the balance sheets under GAAP.

ITEM 7A.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Commodity Price Risk

Our  major  market  risk  exposure  is  in  the  pricing  applicable  to  our  oil  and  natural  gas  production.  Realized  pricing  is  primarily  driven  by  the
prevailing worldwide price for crude oil and spot market prices applicable to our natural gas production. Pricing for oil and natural gas production has been
volatile and unpredictable for several years, and we expect this volatility to continue in the future. The prices we receive for production depend on many
factors outside of our control.

We  use  price  swap  derivatives,  including  basis  swaps,  double-up  swaps,  put  spreads,  interest  rate  swaps  and  three-way  collars,  to  reduce  price
volatility  associated  with  certain  of  our  oil  and  natural  gas  sales.  With  respect  to  these  fixed  price  swap  contracts,  the  counterparty  is  required  to  make  a
payment to us if the settlement price for any settlement period is less than the swap price, and we are required to make a payment to the counterparty if the
settlement price for any settlement period is greater than the swap price. Our derivative contracts are based upon reported settlement prices on commodity
exchanges, with crude oil derivative settlements based on NYMEX West Texas Intermediate pricing (Cushing and Magellan East Houston) and Crude Oil -
Brent and with natural gas derivative settlements based on NYMEX Henry Hub and Waha Hub pricing.

At December 31, 2019 and December 31, 2018, we had a net asset derivative position of $26 million and $216 million, respectively, related to our
price swap, price basis swap derivatives and three-way collars. Utilizing actual derivative contractual volumes under our fixed price swaps and fixed price
basis  swaps  as  of  December  31,  2019,  a  10%  increase  in  forward  curves  associated  with  the  underlying  commodity  would  have  decreased  the  net  asset
position  to  a  net  liability  position  of  $178  million,  a  decrease  of  $204  million,  while  a  10%  decrease  in  forward  curves  associated  with  the  underlying
commodity would have increased the net asset derivative position to $232 million, an increase of $206 million. However, any cash derivative gain or loss
would be substantially offset by a decrease or increase, respectively, in the actual sales value of production covered by the derivative instrument.

Counterparty and Customer Credit Risk

Our principal exposures to credit risk are through receivables resulting from joint interest receivables (approximately $186 million at December 31,

2019) and receivables from the sale of our oil and natural gas production (approximately $429 million at December 31, 2019).

We are subject to credit risk due to the concentration of our oil and natural gas receivables with several significant customers. We do not require our
customers  to  post  collateral,  and  the  inability  of  our  significant  customers  to  meet  their  obligations  to  us  or  their  insolvency  or  liquidation  may  adversely
affect our financial results. For the year ended December 31, 2019, three purchasers each accounted for more than 10% of our revenue: Shell (27%); Plains
(23%); and Vitol (15%).  For  the  year  ended  December 31, 2018,  three  purchasers  each  accounted  for  more  than  10%  of  our  revenue:  Shell  (26%);  Koch
(15%); and Occidental Energy Marketing Inc. (11%).  For  the  year  ended  December 31, 2017,  three  purchasers  each  accounted  for  more  than  10%  of  our
revenue:  Shell  (31%);  Koch  (19%);  and  Enterprise  Crude  Oil  LLC  (11%).  No  other  customer  accounted  for  more  than  10%  of  our  revenue  during  these
periods.

80

Table of Contents

Joint operations receivables arise from billings to entities that own partial interests in the wells we operate. These entities participate in our wells
primarily based on their ownership in leases on which we intend to drill. We have little ability to control whether these entities will participate in our wells. At
December 31, 2019, we had 15 customers that represented approximately 80% of our total joint operations receivables. At December 31, 2018, we had four
customer that represented approximately 82% of our total joint operations receivables.

Interest Rate Risk

We are subject to market risk exposure related to changes in interest rates on our indebtedness under our revolving credit facility. The outstanding
borrowings under the credit agreement bear interest at a per annum rate elected by us that is equal an alternate base rate (which is equal to the greatest of the
prime rate, the Federal Funds effective rate plus 0.50% and 3-month LIBOR plus 1.0%) or LIBOR, in each case plus the applicable margin. The applicable
margin ranges from 0.125% to 1.0% per annum and from 1.125% to 2.0% per annum in the case of LIBOR, in each case, depending on the pricing level,
which in turn depends on the rating agencies’ rating of our unsecured debt. We are obligated to pay a quarterly commitment fee ranging from 0.125% to
0.350% per year on the unused portion of the commitment, based on the pricing level, which in turn depends on the rating agencies’ rating of our unsecured
debt.

As of December 31, 2019, we had $13 million  borrowings  outstanding  under  our  revolving  credit  facility.  Our  weighted  average  interest  rate  on
borrowings  under  our  revolving  credit  facility  was  3.20%  on  December  31,  2019.  An  increase  or  decrease  of  1%  in  the  interest  rate  would  have  a
corresponding  increase  or  decrease  in  our  interest  expense  of  approximately  $130,000  based  on  the  $13  million  outstanding  in  the  aggregate  under  our
revolving credit facility as of such date.

As  of  December  31,  2019,  Viper  LLC  had  $97  million  in  outstanding  borrowings.  Viper  LLC’s  weighted  average  interest  rate  was  4.30%.  An
increase or decrease of 1% in the interest rate would have a corresponding increase or decrease in Viper LLC’s interest expense of approximately $1 million
based on the $97 million outstanding in the aggregate under the Viper credit agreement on December 31, 2019.

As of December 31, 2019, Rattler LLC had $424 million of outstanding borrowings. Rattler LLC’s weighted average interest rate was 2.98%. An
increase or decrease of 1% in the interest rate would have a corresponding increase or decrease in Rattler LLC’s interest expense of approximately $4 million
based on the $424 million outstanding under the Rattler credit agreement as of December 31, 2019.

ITEM 9A.          CONTROLS AND PROCEDURES

Evaluation of Disclosure Control and Procedures

Under the direction of our Chief Executive Officer and Chief Financial Officer, we have established disclosure controls and procedures, as defined in
Rule 13a-15(e) and 15d-15(e) under the Exchange Act that are designed to ensure that information required to be disclosed by us in the reports that we file or
submit  under  the  Exchange  Act  is  recorded,  processed,  summarized  and  reported  within  the  time  periods  specified  in  the  SEC’s  rules  and  forms.  The
disclosure controls and procedures are also intended to ensure that such information is accumulated and communicated to management, including our Chief
Executive  Officer  and  Chief  Financial  Officer,  as  appropriate,  to  allow  timely  decisions  regarding  required  disclosures.  In  designing  and  evaluating  the
disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only
reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there
are resource constraints and that management is required to apply judgment in evaluating the benefits of possible controls and procedures relative to their
costs.

As  of  December  31,  2019,  an  evaluation  was  performed  under  the  supervision  and  with  the  participation  of  management,  including  our  Chief
Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures pursuant to Rule 13a-
15(b) under the Exchange Act. Based upon our evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that as of December 31,
2019, our disclosure controls and procedures are effective.

Changes in Internal Control over Financial Reporting

There have not been any changes in our internal control over financial reporting that occurred during the quarter ended December 31, 2019 that have

materially affected, or are reasonably likely to materially affect, internal controls over financial reporting.

MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

The management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting. The Company’s
internal control over financial reporting is a process designed under the supervision of the Company’s Chief Executive Officer and Chief Financial Officer to
provide reasonable assurance regarding the reliability of financial reporting and the preparation of the Company’s financial statements for external purposes
in accordance with generally accepted accounting principles.

Management conducted an evaluation of the effectiveness of the Company’s internal control over financial reporting based on the framework in the
2013 Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on its evaluation
under the framework in the 2013 Internal Control-Integrated Framework, management did not identify any material weaknesses in the Company’s internal
control over financial reporting and determined that the Company maintained effective internal control over financial reporting as of December 31, 2019.

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.

Grant Thornton LLP, the independent registered public accounting firm that audited the consolidated financial statements of the Company included
in this Annual Report on Form 10-K, has issued their report on the effectiveness of the Company’s internal control over financial reporting at December 31,
2019. The report, which expresses an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting at December 31,
2019, is included in this Item under the heading “Report of Independent Registered Public Accounting Firm.”

We  have  audited  the  internal  control  over  financial  reporting  of  Diamondback  Energy,  Inc.  (a  Delaware  corporation)  and  subsidiaries  (the
“Company”)  as  of  December  31,  2019,  based  on  criteria  established  in  the  2013  Internal  Control-Integrated  Framework  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, 2019, based on the criteria established in the 2013 Internal Control-Integrated Framework issued by COSO.

We  also  have  audited,  in  accordance  with  the  standards  of  the  Public  Company  Accounting  Oversight  Board  (United  States)  (“PCAOB”),  the
consolidated financial statements of the Company as of and for the year ended December 31, 2019,  and  our  report  dated  February 26, 2020  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.

ITEM 9B.     OTHER INFORMATION

Senior Management Severance Plan

Effective  February  20,  2020,  we  adopted  the  Diamondback  Energy,  Inc.  Senior  Management  Severance  Plan,  or  the  Severance  Plan,  and  have
entered into a participation agreement thereunder with each of our named executive officers. Pursuant to the participation agreements, the benefits under the
Severance Plan replace the employment agreements with each of our named executive officers. The Severance Plan also covers other eligible executives who
are selected to participate and replaces any employment agreement they may have.

Payments and Benefits Unrelated to a Change in Control. In the event that the employment of a participating executive is terminated by us other
than for “cause” (and not by reason of death or disability) or if the participant terminates his or her employment for “good reason” (in each case as defined in
the Severance Plan), in addition to any accrued but unpaid base salary or unreimbursed business expenses payable in accordance with the requirements of
applicable law, the participant is entitled to receive severance benefits consisting of:

(i)

(ii)

an amount, if any, equal to the bonus that would be payable for services attributable to a completed prior year performance period that has
not been paid under the terms of the Diamondback Energy, Inc. 2014 Executive Annual Incentive Compensation Plan;

a multiple of base salary continuation for a specified number of months (2x for 24 months for the Chief Executive Officer, 1x for 18 months
for Executive Vice-Presidents, 1x for 15 months for Senior Vice-Presidents and 1x for 12 months for Vice-Presidents);

(iii)

a pro-rated target annual cash bonus for the year of termination (based on the number of days employed during the year of termination);

(iv)

up to 18 months of Company-paid COBRA coverage; and

(v)

the  vesting  or  forfeiture,  as  applicable,  of  each  outstanding  unvested  equity-based  compensation  award  granted  by  us  or  our  affiliates  in
accordance with the terms of the applicable equity award agreement. Mr. Stice’s participation agreement includes terms that are intended to
maintain  certain  benefits  under  his  prior  employment  agreement  and  are  consistent  with  prior  public  disclosure  that  require  each  equity
award granted to Mr. Stice to become 100% vested upon an eligible termination, and in the case of outstanding performance based equity
awards to vest at the maximum level under the equity award agreement, and be settled within ten business days.

Severance Benefits Related to a Change in Control). In the event that employment of a participant is terminated by us other than for “cause” (and
not  by  reason  of  death  or  disability)  or  if  the  participant  terminates  his  or  her  employment  for  “good  reason,”  in  either  case  within  the  two  year  period
immediately following a change in control (as defined in the Severance Plan), the participant will be entitled to the benefits described above, except that the
salary  continuation  described  in  clause  (ii)  will  be  replaced  by  a  lump  sum  cash  payment  equal  to  a  multiple  of  the  participant’s  base  salary  plus  such
participant’s average bonus for the preceding three years (3.0x for the Chief Executive Officer, 2.5x for Executive Vice-Presidents, 2.25x for Senior Vice-
Presidents and 2.0x for Vice-Presidents).

Severance Benefits Related to Death or Disability. The Severance Plan also provides the same benefits described in clauses (i), (ii) and (iii) (but not
clause (iv)) in the event that a participant dies or becomes disabled (as defined in the Severance Agreement) while employed by us. Mr. Stice’s participation
agreement includes terms that are intended to maintain certain benefits under his prior employment agreement and are consistent with prior public disclosure
that require the Company to pay 100 percent of the premiums to continue his, his spouse’s and any of his eligible dependents’ group health plan continuation
coverage under COBRA.

Release and Restrictive Covenants. The payment of any benefits under the Severance Plan is conditioned on the participant’s (or if applicable, the
participant’s personal representative’s or estate’s) execution of a general release of claims. The Severance Plan also includes certain restrictive covenants that
continue  beyond  the  employment  period,  including  non-competition  and  non-solicitation  obligations  for  a  period  of  one  year  following  termination  of
employment. If a participating executive terminates employment on a basis that is not eligible for severance benefits, we can elect to apply the restrictive
covenants for up to 12 months and receive a release by payment of an amount equal to one-twelfth of the participant’s annualized base salary plus target
annual bonus for each month the restrictive covenants will apply.

We believe that these severance benefits provide the same type of income transition protections that were provided to our executives under their prior
employment agreements. These arrangements are intended to attract and retain qualified executives that could have job alternatives that may appear to them
to  be  less  risky  absent  these  arrangements.  We  believe  that  the  enhanced  severance  benefits  resulting  from  terminations  related  to  a  change  in  control
transaction are in the interest of our stockholders because they provide an incentive for executives to continue to help successfully execute such a transaction
from its early stages through consummation. We also believe that these benefits provide important protection to our named executive officers, are consistent
with the prior employment protections and the practices of peer group companies and are appropriate for the attraction and retention of executive talent.

Appointment of Executive Vice President-Operations

On February 20, 2020, our board of directors promoted Daniel N. Wesson to serve as our Executive Vice President-Operations, effective March 1,
2020. Until the effective date of this promotion, Mr. Wesson will continue to serve as our Senior Vice President of Operations, a position he has held since
February 2019. Mr. Wesson served as our Vice President of Operations from April 2017 to February 2019 and as our Completions Manager from January
2013 to April 2017. He joined us as an Operations Engineer in February 2012. Before joining our company, Mr. Wesson served in various operations and
engineering  roles  for  BOPCO  L.P.  from  2010  to  2012  and  ConocoPhillips  from  2007  to  2010.  Mr.  Wesson  received  his  Bachelor  of  Science  degree  in
Mechanical Engineering from Louisiana State University and is a member of the Permian Basin Society of Petroleum Engineers.

In  his  role  as  our  Executive  Vice  President-Operations,  Mr.  Wesson  is  entitled  to  receive  an  annual  base  salary  and  participate  in  (i)  our  annual
executive cash incentive program, which provides an opportunity to receive an annual bonus, based on a target percentage of the annual base salary and pre-
established  performance  goals,  (ii)  our  equity  incentive  plan,  under  which  we  grant  annual  performance-based  and  time-vesting  equity  awards,  (iii)  the
Severance Plan described above and (iv) any other employee benefit plans generally available to similarly situated employees of our company, as in effect
from time to time.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Stockholders
Diamondback Energy, Inc.

Opinion on the financial statements

We have audited the accompanying consolidated balance sheets of Diamondback Energy, Inc. (a Delaware corporation) and subsidiaries (collectively
the “Company”) as of December 31, 2019 and 2018, and the related consolidated statements of operations, stockholders’ equity, and cash flows for each of
the  three  years  in  the  period  ended  December  31,  2019,  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, 2019 and 2018, and the results of its
operations and its cash flows for each of the three years in the period ended December 31, 2019, in conformity with accounting principles generally accepted
in the United States of America.

We  also  have  audited,  in  accordance  with  the  standards  of  the  Public  Company  Accounting  Oversight  Board  (United  States)  (“PCAOB”),  the
Company’s  internal  control  over  financial  reporting  as  of  December  31,  2019,  based  on  criteria  established  in  the  2013  Internal  Control-Integrated
Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), and our report dated February 26, 2020 expressed
an unqualified opinion.

Basis for opinion

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

We  conducted  our  audits  in  accordance  with  the  standards  of  the  PCAOB.  Those  standards  require  that  we  plan  and  perform  the  audit  to  obtain
reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing
procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to
those risks. Such procedures included examining, on a test basis, evidence supporting 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.

Critical audit matter

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

Depletion expense, impairment evaluation and acquisition of oil and gas properties

As  described  in  Note  2  to  the  financial  statements,  the  Company  accounts  for  its  oil  and  gas  properties  using  the  full  cost  method  of  accounting
which  requires  management  to  make  estimates  of  proved  reserve  volumes  and  future  revenues  to  record  depletion  expense  and  measure  its  oil  and  gas
properties for potential impairment. Additionally, as described in Note 3 to the financial statements, the Company acquired significant oil and gas properties
throughout  the  year.  To  estimate  the  volume  of  proved  reserves  and  future  revenues,  management  makes  significant  estimates  and  assumptions  including
forecasting the production decline rate of producing properties, forecasting the timing and volume of production associated with the Company’s development
plan for proved undeveloped properties, and for acquisitions that included proved developed producing properties using an estimated fair value pricing model
for the valuation of proved producing reserves. In  addition,  the  estimation  of  proved  reserves  is  also  impacted  by  management’s  judgments  and  estimates
regarding the financial performance of wells associated with proved reserves to determine if wells are expected, with reasonable certainty, to be economical
under  the  appropriate  pricing  assumptions  required  in  the  estimation  of  depletion  expense  and  potential  impairment  measurements.  We  identified  the
estimation of proved reserves of oil and gas properties, due to its impact on depletion expense, impairment evaluation and acquisition valuation of oil and gas
properties, as a critical audit matter.

F-1

Table of Contents

The principal consideration for our determination that the estimation of proved reserves is a critical audit matter is that relatively minor changes in
certain inputs and assumptions, which require a high degree of subjectivity, necessary to estimate the volume and future revenues of the Company’s proved
reserves  could  have  a  significant  impact  on  the  measurement  of  depletion  expense  or  impairment  expense.  In  turn,  auditing  those  inputs  and  assumptions
required subjective and complex auditor judgment.
Our audit procedures related to the estimation of proved reserves included the following, among others.

◦ We tested the design and operating effectiveness of key controls relating to the preparation of the ceiling test calculation, management’s estimation

of proved reserves for the purpose of estimating depletion expense and assessing the Company’s oil and gas properties for potential impairment, and
management’s estimation of the fair value of acquired oil and gas properties. Specifically, these controls related to the use of historical information in
the estimation of proved reserves derived from the Company’s accounting records and the management review controls on information provided to
the reservoir engineering specialists and the management review controls on the final proved reserve report prepared by the Company’s specialists.

◦ We evaluated the level of knowledge, skill, and ability of the Company’s reservoir engineering specialists and their relationship to the Company,
made inquiries of those reservoir engineers regarding the process followed and judgments made to estimate the Company’s proved reserve volumes,
and read the reserve report prepared by the Company’s specialists.

◦

◦

For  acquisitions  of  oil  and  gas  properties  during  the  year  in  which  proved  developed  producing  properties  are  significant  and  to  the  extent  key,
sensitive  inputs  and  assumptions  used  to  determine  proved  reserve  volumes  and  other  cash  flow  inputs  and  assumptions  are  derived  from  the
Company’s  accounting  records,  such  as  historical  pricing  differentials,  working  and  net  revenue  interests  and  future  capital  expenditures  and
operating  costs,  we  tested  management’s  process  for  determining  the  assumptions,  including  examining  the  underlying  support.  Specifically,  our
audit procedures involved testing management’s assumptions as follows:

◦

◦

◦

◦

◦

Analyzed  the  appropriateness  of  fair  value  pricing  used  in  the  acquisition  reserve  report  to  published  product  pricing  on  the  acquisition
closing date;
Analyzed  the  appropriateness  of  the  future  operating  cost  and  capital  expenditure  assumptions  used  in  the  acquisition  reserve  report  to
historical operating costs and capital expenditures of similarly located properties
Evaluated the working and net revenue interests used in the acquisition reserve report by inspecting a sample of land and division order
records;
Analyzed, on a sample basis, the appropriateness of management’s estimated future production volumes and the production decline curves;
and
Utilized  valuation  specialists  to  compare  the  acreage  value  allocated,  on  a  per  acre  basis,  to  undeveloped  properties  and  to  other  recent
acquisitions in the same or similar locations.

To  the  extent  key,  sensitive  inputs  and  assumptions  used  to  determine  proved  reserve  volumes  and  other  cash  flow  inputs  and  assumptions  are
derived from the Company’s accounting records, such as historical pricing differentials, operating costs, estimated capital costs and working and net
revenue interests, we tested management’s process for determining the assumptions, including examining the underlying support, on a sample basis.
Specifically, our audit procedures involved testing management’s assumptions as follows:

◦

◦
◦

◦
◦

◦

◦

Compared  the  estimated  pricing  differentials  used  in  the  reserve  report  to  realized  prices  related  to  revenue  transactions  recorded  in  the
current year and examined contractual support for the pricing differentials;
Evaluated the models used to estimate the operating costs at year-end compared to historical operating costs;
Compared  the  models  used  to  determine  the  future  capital  expenditures  and  compared  estimated  future  capital  expenditures  used  in  the
reserve report to amounts expended for recently drilled and completed wells with similar locations;
Evaluated the working and net revenue interests used in the reserve report by inspecting a sample of land and division order records;
Evaluated the Company’s evidence supporting the amount of proved undeveloped properties reflected in the reserve report by examining
historical conversion rates and support for the operator’s intent to develop the proved undeveloped properties;
Evaluated  the  estimated  ultimate  recovery  of  proved  undeveloped  properties  to  the  estimated  ultimate  recovery  of  comparable  proved
developed producing properties; and
Applied analytical procedures to the reserve report by comparing to historical actual results and to the prior year reserve report.

Notes to Consolidated Financial Statements

1.    DESCRIPTION OF THE BUSINESS AND BASIS OF PRESENTATION

Organization and Description of the Business

Diamondback Energy, Inc. (“Diamondback” or the “Company”) is an independent oil and gas company focused on the acquisition, development,
exploration and exploitation of unconventional, onshore oil and natural gas reserves in the Permian Basin in West Texas. Diamondback was incorporated in

Basis of Presentation

The  consolidated  financial  statements  include  the  accounts  of  the  Company  and  its  subsidiaries  after  all  significant  intercompany  balances  and

transactions have been eliminated upon consolidation.

Viper is consolidated in the financial statements of the Company. As of December 31, 2019, the Company owned approximately 58% of the total

units outstanding of Viper and the Company’s wholly owned subsidiary, Viper Energy Partners GP LLC, is Viper’s General Partner.

Rattler is consolidated in the financial statements of the Company. As of December 31, 2019, the Company owned approximately 71% of the total

units outstanding of Rattler. The Company’s wholly-owned subsidiary, Rattler Midstream GP LLC, is Rattler’s General Partner.

2.    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Use of Estimates

Certain amounts included in or affecting the Company’s consolidated financial statements and related disclosures must be estimated by management,
requiring  certain  assumptions  to  be  made  with  respect  to  values  or  conditions  that  cannot  be  known  with  certainty  at  the  time  the  consolidated  financial
statements are prepared. These estimates and assumptions affect the amounts the Company reports for assets and liabilities and the Company’s disclosure of
contingent assets and liabilities at the date of the consolidated financial statements. Actual results could differ from those estimates.

The Company evaluates these estimates on an ongoing basis, using historical experience, consultation with experts and other methods the Company
considers reasonable in the particular circumstances. Nevertheless, actual results may differ significantly from the Company’s estimates. Any effects on the
Company’s business, financial position or results of operations resulting from revisions to these estimates are recorded in the period in which the facts that
give rise to the revision become known. Significant items subject to such estimates and assumptions include, but are not limited to, estimates of proved oil
and  natural  gas  reserves  and  related  present  value  estimates  of  future  net  cash  flows  therefrom,  the  carrying  value  of  oil  and  natural  gas  properties,  asset
retirement  obligations,  the  fair  value  determination  of  acquired  assets  and  liabilities,  equity-based  compensation,  fair  value  estimates  of  commodity
derivatives and estimates of income taxes.

Cash and Cash Equivalents

Diamondback Energy, Inc. and Subsidiaries
Notes to Consolidated Financial Statements-(Continued)

The  Company  considers  all  highly  liquid  investments  purchased  with  a  maturity  of  three  months  or  less  and  money  market  funds  to  be  cash
equivalents.  The  Company  maintains  cash  and  cash  equivalents  in  bank  deposit  accounts  which,  at  times,  may  exceed  the  federally  insured  limits.  The
Company has not experienced any significant losses from such investments.

Restricted Cash

As  of  December  31,  2019,  the  Company  had  restricted  cash  of  $5  million  related  to  the  Company’s  obligations  under  its  participation  and

development agreement with Obsidian Resources, L.L.C.

Accounts Receivable

Accounts  receivable  consist  of  receivables  from  joint  interest  owners  on  properties  the  Company  operates  and  from  sales  of  oil  and  natural  gas
production delivered to purchasers. The purchasers remit payment for production directly to the Company. Most payments for production are received within
three months after the production date.

Accounts  receivable  are  stated  at  amounts  due  from  joint  interest  owners  or  purchasers,  net  of  an  allowance  for  doubtful  accounts  when  the
Company  believes  collection  is  doubtful.  For  receivables  from  joint  interest  owners,  the  Company  typically  has  the  ability  to  withhold  future  revenue
disbursements  to  recover  any  non-payment  of  joint  interest  billings.  Accounts  receivable  outstanding  longer  than  the  contractual  payment  terms  are
considered past due. The Company determines its allowance by considering a number of factors, including the length of time accounts receivable are past
due,  the  Company’s  previous  loss  history,  the  debtor’s  current  ability  to  pay  its  obligation  to  the  Company,  the  condition  of  the  general  economy  and  the
industry  as  a  whole.  The  Company  writes  off  specific  accounts  receivable  when  they  become  uncollectible,  and  payments  subsequently  received  on  such
receivables are credited to the allowance for doubtful accounts. At December 31, 2019 and 2018, the Company recorded an allowance for doubtful accounts
of $2 million related to joint interest receivables.

Derivative Instruments

The Company is required to recognize its derivative instruments on the consolidated balance sheets as assets or liabilities at fair value with such
amounts classified as current or long-term based on their anticipated settlement dates. The accounting for the changes in fair value of a derivative depends on
the intended use of the derivative and resulting designation. The Company has not designated its derivative instruments as hedges for accounting purposes
and, as a result, marks its derivative instruments to fair value and recognizes the cash and non-cash change in fair value on derivative instruments for each
period in the consolidated statements of operations.

Fair Value of Financial Instruments

The Company’s financial instruments consist of cash and cash equivalents, restricted cash, receivables, payables, derivatives and senior notes. The
carrying amount of cash and cash equivalents, receivables and payables approximates fair value because of the short-term nature of the instruments. The fair
value of the revolving credit facility approximates its carrying value based on the borrowing rates currently available to the Company for bank loans with
similar terms and maturities. The fair value of the senior notes are determined using quoted market prices. Derivatives are recorded at fair value (see Note 16
—Fair Value Measurements).

The  Company  uses  the  full  cost  method  of  accounting  for  its  oil  and  natural  gas  properties.  Under  this  method,  all  acquisition,  exploration  and
development costs, including certain internal costs, are capitalized and amortized on a composite unit of production method based on proved oil, natural gas
liquids  and  natural  gas  reserves.  Internal  costs  capitalized  to  the  full  cost  pool  represent  management’s  estimate  of  costs  incurred  directly  related  to
exploration  and  development  activities  such  as  geological  and  other  administrative  costs  associated  with  overseeing  the  exploration  and  development
activities. Costs, including related employee costs, associated with production and operation of the properties are charged to expense as incurred. All other
internal costs not directly associated with exploration and development activities are charged to expense as they are incurred. Sales  of  oil  and  natural  gas
properties,  whether  or  not  being  amortized  currently,  are  accounted  for  as  adjustments  of  capitalized  costs,  with  no  gain  or  loss  recognized,  unless  such
adjustments would significantly alter the relationship between capitalized costs and proved reserves of oil, natural gas liquids and natural gas. Any income
from services provided by subsidiaries to working interest owners of properties in which the Company also owns an interest, to the extent they exceed related
costs  incurred,  are  accounted  for  as  reductions  of  capitalized  costs  of  oil  and  natural  gas  properties  proportionate  to  the  Company’s  investment  in  the
subsidiary (see Note 9–Equity Method Investments). Depletion of evaluated oil and natural gas properties is computed on the units of production method,
whereby capitalized costs plus estimated future development costs are amortized over total proved reserves. The average depletion rate per barrel equivalent
unit  of  production  was  $13.54,  $12.62  and  $11.11  for  the  years  ended  December  31,  2019,  2018  and  2017,  respectively.  Depreciation,  depletion  and
amortization expense for oil and natural gas properties was $1.4 billion, $595 million and $321 million for the years ended December 31, 2019, 2018  and
2017, respectively.

Under this method of accounting, the Company is required to perform a ceiling test each quarter. The test determines a limit, or ceiling, on the book
value of the proved oil and natural gas properties. Net capitalized costs are limited to the lower of unamortized cost net of deferred income taxes, or the cost
center ceiling. The cost center ceiling is defined as the sum of (a) estimated future net revenues, discounted at 10% per annum, from proved reserves, based
on  the  trailing  12-month  unweighted  average  of  the  first-day-of-the-month  price,  adjusted  for  any  contract  provisions,  and  excluding  the  estimated
abandonment costs for properties with asset retirement obligations recorded on the balance sheet, (b) the cost of properties not being amortized, if any, and (c)
the lower of cost or market value of unproved properties included in the cost being amortized, including related deferred taxes for differences between the
book and tax basis of the oil and natural gas properties. If the net book value, including related deferred taxes, exceeds the ceiling, an impairment or non-cash
writedown is required. An  impairment  on  proved  oil  and  natural  gas  properties  of  $790 million  was  recorded  for  the  year  ended  December  31,  2019.  No
impairments on proved oil and natural gas properties were recorded for the years ended December 31, 2018 and 2017.

Costs associated with unevaluated properties are excluded from the full cost pool until the Company has made a determination as to the existence of
proved  reserves.  The  Company  assesses  all  items  classified  as  unevaluated  property  on  an  annual  basis  for  possible  impairment.  The  Company  assesses
properties on an individual basis or as a group if properties are individually insignificant. The assessment includes consideration of the following factors,
among others: intent to drill; remaining lease term; geological and geophysical evaluations; drilling results and activity; the assignment of proved reserves;
and the economic viability of development if proved reserves are assigned. During any period in which these factors indicate an impairment, the cumulative
drilling costs incurred to date for such property and all or a portion of the associated leasehold costs are transferred to the full cost pool and are then subject to
amortization.

Real Estate Assets

Diamondback Energy, Inc. and Subsidiaries
Notes to Consolidated Financial Statements-(Continued)

Real estate assets are stated at cost, less accumulated depreciation and amortization. The Company considers the period of future benefit of each
respective asset to determine the appropriate useful life and depreciation and amortization is calculated using the straight-line method over the assigned useful
life.

Upon  acquisition  of  real  estate  properties,  the  purchase  price  is  allocated  to  tangible  assets,  consisting  of  land  and  building,  and  to  identified
intangible assets and liabilities, which may include the value of above market and below market leases and the value of in-place leases. The allocation of the
purchase price is based upon the fair value of each component of the property. Although independent appraisals may be used to assist in the determination of
fair  value,  in  many  cases  these  values  will  be  based  upon  management’s  assessment  of  each  property,  the  selling  prices  of  comparable  properties  and  the
discounted value of cash flows from the asset.

The fair values of above market and below market in-place leases will be recorded based on the present value (using an interest rate which reflects
the  risks  associated  with  the  leases  acquired)  of  the  difference  between  (i)  the  contractual  amounts  to  be  paid  pursuant  to  the  in-place  leases  and  (ii)  an
estimate of fair market lease rates for the corresponding in-place leases measured over a period equal to the non-cancelable term of the lease including any
bargain  renewal  periods.  The  above  market  and  below  market  lease  values  will  be  capitalized  as  intangible  lease  assets  or  liabilities.  Above  market  lease
values will be amortized as an adjustment of rental income over the remaining term of the respective leases. Below market lease values will be amortized as
an adjustment of rental income over the remaining term of the respective leases, including any bargain renewal periods. If a lease were to be terminated prior
to  its  stated  expiration,  all  unamortized  amounts  of  above  market  and  below  market  in-place  lease  values  relating  to  that  lease  would  be  recorded  as  an
adjustment to rental income.

The fair values of in-place leases will include estimated direct costs associated with obtaining a new tenant, and opportunity costs associated with
lost  rentals  which  are  avoided  by  acquiring  an  in-place  lease.  Direct  costs  associated  with  obtaining  a  new  tenant  may  include  commissions,  tenant
improvements, and other direct costs and are estimated, in part, by management’s consideration of current market costs to execute a similar lease.

These direct costs will be included in intangible lease assets on the balance sheet and will be amortized to expense over the remaining term of the
respective leases. The value of opportunity costs will be calculated using the contractual amounts to be paid pursuant to the in-place leases over a market
absorption period for a similar lease. These intangibles will be included in intangible lease assets on the balance sheet and will be amortized to expense over
the remaining term of the respective leases. If a lease were to be terminated prior to its stated expiration, all unamortized amounts of in-place lease assets
relating to that lease would be expensed.

Other Property, Equipment and Land

Other  property  and  equipment  is  recorded  at  cost.  The  Company  expenses  maintenance  and  repairs  in  the  period  incurred.  Upon  retirements  or
disposition of assets, the cost and related accumulated depreciation are removed from the consolidated balance sheet with the resulting gains or losses, if any,
reflected  in  operations.  Depreciation  of  other  property  and  equipment  is  computed  using  the  straight  line  method  over  their  estimated  useful  lives,  which
range  from  three  to  15  years.  Depreciation  expense  for  other  property  and  equipment  was  $16  million,  $9  million  and  $1  million  for  the  years  ended
December 31, 2019, 2018 and 2017, respectively.

Asset Retirement Obligations

The Company measures the future cost to retire its tangible long-lived assets and recognizes such cost as a liability for legal obligations associated

with the retirement of long-lived assets that result from the acquisition, construction or normal operation of a long-lived asset.

The Company records a liability relating to the retirement and removal of all assets used in their businesses. Asset retirement obligations represent
the future abandonment costs of tangible assets, namely wells. The fair value of a liability for an asset’s retirement obligation is recorded in the period in
which it is incurred if a reasonable estimate of fair value can be made and the corresponding cost is capitalized as part of the carrying amount of the related
long-lived asset. The liability is accreted to its then present value each period, and the capitalized cost is depreciated over the useful life of the related asset. If
the  liability  is  settled  for  an  amount  other  than  the  recorded  amount  or  if  there  is  a  change  in  the  estimated  liability,  the  difference  is  recorded  in  oil  and
natural gas properties.

Impairment of Long-Lived Assets

Other property and equipment used in operations are reviewed whenever events or circumstances indicate that the carrying amount of an asset may
not  be  recoverable.  An  impairment  loss  is  recognized  only  if  the  carrying  amount  of  a  long-lived  asset  is  not  recoverable  from  its  estimated  future
undiscounted cash flows. An impairment loss is the difference between the carrying amount and fair value of the asset. The Company had no such impairment
losses for the years ended December 31, 2019, 2018 and 2017, respectively.

Capitalized Interest

The  Company  capitalizes  interest  on  expenditures  made  in  connection  with  exploration  and  development  projects  that  are  not  subject  to  current
amortization. Interest is capitalized only for the period that activities are in progress to bring these unevaluated properties to their intended use. Capitalized
interest cannot exceed gross interest expense. The Company capitalized interest of $66 million, $32 million and $22 million for the years ended December 31,
2019, 2018 and 2017, respectively.

Inventories

Inventories are stated at the lower of cost or market and consist of tubular goods and equipment at December 31, 2019 and 2018. The Company’s
tubular goods and equipment are primarily comprised of oil and natural gas drilling or repair items such as tubing, casing and pumping units. The inventory is
primarily acquired for use in future drilling or repair operations and is carried at lower of cost or market. “Market”, in the context of inventory valuation,
represents net realizable value, which is the amount that the Company is allowed to bill to the joint accounts under joint operating agreements to which the
Company is a party. As of December 31, 2019, the Company estimated that all of its tubular goods and equipment will be utilized within one year.

Debt Issuance Costs

Other assets included capitalized costs related to the credit facility of $36 million and $28 million, net of accumulated amortization of $15 million
and $9 million, as of December 31, 2019 and 2018, respectively. Long-term debt included capitalized costs related to the senior notes of $24 million and $32
million,  net  of  accumulated  amortization  of  $14 million  and  $15 million, as of December  31,  2019  and  2018,  respectively.  The  costs  associated  with  the
senior notes are being netted against the senior notes balances and are being amortized over the term of the senior notes using the effective interest method.
The costs associated with the Company’s credit facility that are included in other assets are being amortized over the term of the facility.

Revenue and Royalties Payable

Diamondback Energy, Inc. and Subsidiaries
Notes to Consolidated Financial Statements-(Continued)

For certain oil and natural gas properties, where the Company serves as operator, the Company receives production proceeds from the purchaser and
further  distributes  such  amounts  to  other  revenue  and  royalty  owners.  Production  proceeds  that  the  Company  has  not  yet  distributed  to  other  revenue  and
royalty owners are reflected as revenue and royalties payable in the accompanying consolidated balance sheets. The Company recognizes revenue for only its
net revenue interest in oil and natural gas properties.

Revenue Recognition

Revenue from Contracts with Customers

Sales of oil, natural gas and natural gas liquids are recognized at the point control of the product is transferred to the customer. Virtually all of the
pricing provisions in the Company’s contracts are tied to a market index, with certain adjustments based on, among other factors, whether a well delivers to a
gathering or transmission line, the quality of the oil or natural gas and the prevailing supply and demand conditions. As a result, the price of the oil, natural
gas and natural gas liquids fluctuates to remain competitive with other available oil, natural gas and natural gas liquids supplies.

Oil sales

The  Company’s  oil  sales  contracts  are  generally  structured  where  it  delivers  oil  to  the  purchaser  at  a  contractually  agreed-upon  delivery  point  at
which the purchaser takes custody, title and risk of loss of the product. Under this arrangement, the Company or a third party transports the product to the
delivery point and receives a specified index price from the purchaser with no deduction. In this scenario, the Company recognizes revenue when control
transfers to the purchaser at the delivery point based on the price received from the purchaser. Oil revenues are recorded net of any third-party transportation
fees and other applicable differentials in the Company’s consolidated statements of operations.

Natural gas and natural gas liquids sales

Under the Company’s natural gas processing contracts, it delivers natural gas to a midstream processing entity at the wellhead, battery facilities or
the  inlet  of  the  midstream  processing  entity’s  system.  The  midstream  processing  entity  gathers  and  processes  the  natural  gas  and  remits  proceeds  to  the
Company for the resulting sales of natural gas liquids and residue gas. In these scenarios, the Company evaluates whether it is the principal or the agent in the
transaction. For those contracts where the Company has concluded it is the principal and the ultimate third party is its customer, the Company recognizes
revenue on a gross basis, with transportation, gathering, processing, treating and compression fees presented as an expense in its consolidated statements of
operations.

In certain natural gas processing agreements, the Company may elect to take its residue gas and/or natural gas liquids in-kind at the tailgate of the
midstream entity’s processing plant and subsequently market the product. Through the marketing process, the Company delivers product to the ultimate third-
party  purchaser  at  a  contractually  agreed-upon  delivery  point  and  receives  a  specified  index  price  from  the  purchaser.  In  this  scenario,  the  Company
recognizes  revenue  when  control  transfers  to  the  purchaser  at  the  delivery  point  based  on  the  index  price  received  from  the  purchaser.  The  gathering,
processing, treating and compression fees attributable to the gas processing contract, as well as any transportation fees incurred to deliver the product to the
purchaser, are presented as transportation, gathering, processing, treating and compression expense in its consolidated statements of operations.

Midstream Revenue

Substantially all revenues from gathering, compression, water handling, disposal and treatment operations are derived from intersegment transactions
for services Rattler provides to exploration and production operations. The portion of such fees shown in the Company’s consolidated financial statements
represent amounts charged to interest owners in the Company’s operated wells, as well as fees charged to other third parties for water handling and treatment
services  provided  by  Rattler  or  usage  of  Rattler’s  gathering  and  compression  systems.  For  gathering  and  compression  revenue,  Rattler  satisfies  its
performance obligations and recognizes revenue when low pressure volumes are delivered to a specified delivery point. Revenue is recognized based on the
per MMbtu gathering fee or a per barrel gathering fee charged by Rattler in accordance with the gathering and compression agreement. For water handling
and  treatment  revenue,  Rattler  satisfies  its  performance  obligations  and  recognizes  revenue  when  the  water  volumes  have  been  delivered  to  the  fracwater
meter for a specified well pad and the wastewater volumes

F-16

Table of Contents

Diamondback Energy, Inc. and Subsidiaries
Notes to Consolidated Financial Statements-(Continued)

have been metered downstream of the Company’s facilities. For services contracted through third party providers, Rattler’s performance obligation is satisfied
when the service performed by the third party provider has been completed. Revenue is recognized based on the per barrel water delivery or a wastewater
gathering and disposal fee charged by Rattler in accordance with the water services agreement.

Transaction price allocated to remaining performance obligations

The Company’s upstream product sales contracts do not originate until production occurs and, therefore, are not considered to exist beyond each

days’ production. Therefore, there are no remaining performance obligations under any of our product sales contracts.

The majority of the Company’s midstream revenue agreements have a term greater than one year, and as such the Company has utilized the practical
expedient in ASC 606, which states that the Company is not required to disclose the transaction price allocated to remaining performance obligations if the
variable consideration is allocated entirely to a wholly unsatisfied performance obligation. Under its revenue agreements, each delivery generally represents a
separate  performance  obligation;  therefore,  future  volumes  delivered  are  wholly  unsatisfied  and  disclosure  of  the  transaction  price  allocated  to  remaining
performance obligations is not required.

The remainder of the Company’s midstream revenue agreements, which relate to agreements with third parties, are short-term in nature with a term
of  one  year  or  less.  The  Company  has  utilized  an  additional  practical  expedient  in  ASC  606  which  exempts  it  from  disclosure  of  the  transaction  price
allocated to remaining performance obligations if the performance obligation is part of an agreement that has an original expected duration of one year or less.

Contract balances

Under the Company’s product sales contracts, it has the right to invoice its customers once the performance obligations have been satisfied, at which

point payment is unconditional. Accordingly, the Company’s product sales contracts do not give rise to contract assets or liabilities under ASC 606.

Prior-period performance obligations

The  Company  records  revenue  in  the  month  production  is  delivered  to  the  purchaser.  However,  settlement  statements  for  certain  natural  gas  and
natural gas liquids sales may not be received for 30 to 90 days after the date production is delivered, and as a result, the Company is required to estimate the
amount of production delivered to the purchaser and the price that will be received for the sale of the product. The Company records the differences between
its estimates and the actual amounts received for product sales in the month that payment is received from the purchaser. The Company has existing internal
controls  for  its  revenue  estimation  process  and  related  accruals,  and  any  identified  differences  between  its  revenue  estimates  and  actual  revenue  received
historically have not been significant. For the year ended December 31, 2019, revenue recognized in the reporting period related to performance obligations
satisfied in prior reporting periods was not material. The Company believes that the pricing provisions of its oil, natural gas and natural gas liquids contracts
are customary in the industry. To the extent actual volumes and prices of oil and natural gas sales are unavailable for a given reporting period because of
timing  or  information  not  received  from  third  parties,  the  revenue  related  to  expected  sales  volumes  and  prices  for  those  properties  are  estimated  and
recorded.

Investments

Equity investments in which the Company exercises significant influence but does not control are accounted for using the equity method. Under the
equity  method,  generally  the  Company’s  share  of  investees’  earnings  or  loss  is  recognized  in  the  statement  of  operations.  The  Company  reviews  its
investments to determine if a loss in value which is other than a temporary decline has occurred. If such loss has occurred, the Company would recognize an
impairment provision. There was no impairment for the Company’s equity investments for the years ended December 31, 2019, 2018 and 2017.

For additional information on the Company’s investments, see Note 9—Equity Method Investments.

Notes to Consolidated Financial Statements-(Continued)

Accounting for Equity-Based Compensation

The Company has granted various types of stock-based awards including stock options and restricted stock units. Viper has granted various unit-
based  awards  including  unit  options  and  phantom  units  to  employees,  officers  and  directors  of  Viper’s  General  Partner  and  the  Company  who  perform
services for Viper. Rattler has granted unit-based awards consisting of phantom units to employees, officers and directors of Rattler’s General Partner and the
Company  who  perform  services  for  Rattler.  These  plans  and  related  accounting  policies  are  defined  and  described  more  fully  in  Note  12—Equity-Based
Compensation. Equity compensation awards are measured at fair value on the date of grant and are expensed, net of estimated forfeitures, over the required
service period.

Concentrations

The  Company  is  subject  to  risk  resulting  from  the  concentration  of  its  crude  oil  and  natural  gas  sales  and  receivables  with  several  significant
purchasers. For the year ended December 31, 2019, three purchasers each accounted for more than 10% of our revenue: Shell (27%); Plains (23%); and Vitol
(15%). For the year ended December 31, 2018, three purchasers each accounted for more than 10% of the Company’s revenue: Shell (26%); Koch (15%); and
Occidental Energy Marketing Inc. (11%).  For  the  year  ended  December  31,  2017,  three  purchasers  each  accounted  for  more  than  10%  of  the  Company’s
revenue: Shell (31%); Koch (19%); and Enterprise Crude Oil LLC (11%). The Company does not require collateral and does not believe the loss of any single
purchaser  would  materially  impact  its  operating  results,  as  crude  oil  and  natural  gas  are  fungible  products  with  well-established  markets  and  numerous
purchasers.

Environmental Compliance and Remediation

Environmental compliance and remediation costs, including ongoing maintenance and monitoring, are expensed as incurred. Liabilities are accrued

when environmental assessments and remediation are probable, and the costs can be reasonably estimated.

Income Taxes

Diamondback uses the asset and liability method of accounting for income taxes, under which deferred tax assets and liabilities are recognized for
the future tax consequences of (i) temporary differences between the financial statement carrying amounts and the tax bases of existing assets and liabilities
and (ii) operating loss and tax credit carryforwards. Deferred income tax assets and liabilities are based on enacted tax rates applicable to the future period
when those temporary differences are expected to be recovered or settled. The effect of a change in tax rates on deferred tax assets and liabilities is recognized
in income in the period the rate change is enacted. A valuation allowance is provided for deferred tax assets when it is more likely than not the deferred tax
assets will not be realized.

The Company is subject to margin tax in the state of Texas. During the years ended December 31, 2019, 2018 and 2017, the Company had no margin
tax expense. The Company’s 2015, 2016, 2017, 2018 and 2019 federal income tax and state margin tax returns remain open to examination by tax authorities.
As  of  December  31,  2019  and  2018,  we  had  $2  million  unrecognized  tax  benefits.  The  Company  is  continuing  its  practice  of  recognizing  interest  and
penalties related to income tax matters as interest expense and general and administrative expenses, respectively. During the years ended December 31, 2019,
2018 and 2017, there was no interest or penalties associated with uncertain tax positions recognized in the Company’s consolidated financial statements.

Energen Corporation Merger

On November 29, 2018, the Company completed its acquisition of Energen in an all-stock transaction (the “ Merger”), which was accounted for as a
business  combination.  Upon  completion  of  the  Merger,  the  addition  of  Energen’s  assets  increased  the  Company’s  assets  to:  (i)  over  273,000 net Tier One
acres in the Permian Basin, (ii) approximately 7,200 estimated total net horizontal Permian locations, and (iii) approximately 394,000 net acres across the
Midland and Delaware Basins. Under the terms of the Merger, each share of Energen common stock was converted into 0.6442 of a share of the Company’s
common stock. The Company issued approximately 62.8 million shares of its common stock valued at a price of $112.00 per share on

F-20

shares  of  common  stock  and  equity  awards  as  of  the  closing  date  of  the  Merger,  (ii)  the  depletion  of  Energen’s  fair-valued  proved  oil  and  natural  gas
properties and (iii) the estimated tax impacts of the pro forma adjustments.

Additionally, pro forma earnings were adjusted to exclude acquisition-related costs incurred by the Company of approximately $37 million for the
year ended December 31, 2018 and acquisition-related costs incurred by Energen of $59 million. The pro forma results of operations do not include any cost
savings or other synergies that may result from the Merger or any estimated costs that have been or will be incurred by the Company to integrate the Energen
assets.  The  pro  forma  financial  data  does  not  include  the  results  of  operations  for  any  other  acquisitions  made  during  the  periods  presented,  as  they  were
primarily acreage acquisitions and their results were not deemed material.

The pro forma consolidated statement of operations data has been included for comparative purposes only and is not necessarily indicative of the

results that might have occurred had the Merger taken place on January 1, 2017 and is not intended to be a projection of future results.

Viper is a publicly traded Delaware limited partnership, the common units of which are listed on the Nasdaq Global Select Market under the symbol
“VNOM”. Viper was formed by Diamondback on February 27, 2014, to, among other things, own, acquire and exploit oil and natural gas properties in North
America.  Viper  is  currently  focused  on  oil  and  natural  gas  properties  in  the  Permian  Basin.  Viper  Energy  Partners  GP  LLC,  a  consolidated  subsidiary  of
Diamondback, serves as the general partner of, and holds a general partner interest in, Viper. As of December 31, 2019, the Company owned approximately
58% of Viper’s total units outstanding.

During the year ended December 31, 2019, Diamondback received distributions of $133 million in respect of its interests in Viper and Viper LLC.

Viper completed the following equity offerings during the years ended December 31, 2019, 2018 and 2017:

officers  and  directors  of  the  Company  and  the  General  Partner  purchased  an  aggregate  of  114,000  common  units,  in  each  case  directly  from  the
underwriters.

As a result of Viper’s public offerings, Viper’s issuance of units for acquisitions and Viper’s issuance of unit-based compensation, the Company’s
ownership percentage in Viper was reduced. During the year ended December 31, 2019,  the  Company  recorded  a  $45 million  decrease  to  non-controlling
interest in Viper with an increase to additional paid-in capital, which represents the difference between the Company’s share of the underlying net book value
in Viper before and after the respective Partnership common unit transactions, on the Company’s consolidated balance sheet.

Recapitalization, Tax Status Election and Related Transactions by Viper

In March 2018, Viper announced that the Board of Directors of the General Partner had unanimously approved a change of Viper’s federal income
tax status from that of a pass-through partnership to that of a taxable entity via a “check the box” election. In connection with making this election, on May 9,
2018  Viper  (i)  amended  and  restated  its  First  Amended  and  Restated  Partnership  Agreement,  (ii)  amended  and  restated  the  First  Amended  and  Restated
Limited Liability Company Agreement of the Operating Company, (iii) amended and restated its existing registration rights agreement with the Company and
(iv) entered into an exchange agreement with the Company, the General Partner and the Operating Company. Simultaneously with the effectiveness of these
agreements,  the  Company  delivered  and  assigned  to  Viper  the  73,150,000  common  units  the  Company  owned  in  exchange  for  (i)  73,150,000  of  Viper’s
newly-issued Class B units and (ii) 73,150,000 newly-issued units of the Operating Company pursuant to the terms of a Recapitalization Agreement dated
March  28,  2018,  as  amended  as  of  May  9,  2018  (the  “Recapitalization  Agreement”).  Immediately  following  that  exchange,  Viper  continued  to  be  the
managing  member  of  the  Operating  Company,  with  sole  control  of  its  operations,  and  owned  approximately  36%  of  the  outstanding  units  issued  by  the
Operating Company, and the Company owned the remaining approximately 64% of the outstanding units issued by the Operating Company. Upon completion
of Viper’s July 2018 offering of units, it owned approximately 41% of the outstanding units issued by the Operating Company and the Company owned the
remaining  approximately  59%.  The  Operating  Company  units  and  Viper’s  Class  B  units  owned  by  the  Company  are  exchangeable  from  time  to  time  for
Viper’s common units (that is, one Operating Company unit and one Partnership Class B unit, together, will be exchangeable for one Partnership common
unit).

On May 10, 2018, the change in Viper’s income tax status became effective. On that date, pursuant to the terms of the Recapitalization Agreement,
(i) the General Partner made a cash capital contribution of $1 million to Viper in respect of its general partner interest and (ii) the Company made a cash
capital contribution of $1 million to Viper in respect of the Class B units. The Company, as the holder of the Class B units, and the General Partner, as the
holder  of  the  general  partner  interest,  are  entitled  to  receive  an  8%  annual  distribution  on  the  outstanding  amount  of  these  capital  contributions,  payable
quarterly,  as  a  return  on  this  invested  capital.  On  May  10,  2018,  the  Company  also  exchanged  731,500  Class  B  units  and  731,500  units  in  the  Operating
Company for 731,500 common units of Viper and a cash amount of $10,000 representing a proportionate return of the $1 million invested capital in respect of
the Class B units. The General Partner continues to serve as Viper’s general partner and the Company continues to control Viper. After the effectiveness of the
tax status election and the completion of related transactions, Viper’s minerals business continues to be conducted through the Operating Company, which
continues  to  be  taxed  as  a  partnership  for  federal  and  state  income  tax  purposes.  This  structure  is  anticipated  to  provide  significant  benefits  to  Viper’s
business,  including  operational  effectiveness,  acquisition  and  disposition  transactional  planning  flexibility  and  income  tax  efficiency.  For  additional
information regarding the tax status election and related transactions, please refer to Viper’s Definitive Information Statement on Schedule 14C filed with the
SEC on April 17, 2018 and Viper’s Current Report on Form 8-K filed with the SEC on May 15, 2018.

Partnership Agreement

The second amended and restated agreement of limited partnership, dated as of May 9, 2018, as amended as of May 10, 2018 (the “Viper Partnership
Agreement”), requires Viper to reimburse Viper’s General Partner for all direct and indirect expenses incurred or paid on Viper’s behalf and all other expenses
allocable to Viper or otherwise incurred by Viper’s General Partner in connection with operating Viper’s business. The Viper Partnership Agreement does not
set a limit on the amount of expenses for which Viper’s General Partner and its affiliates may be reimbursed. These expenses include salary, bonus, incentive
compensation and other amounts paid to persons who perform services for Viper or on its behalf and expenses allocated to Viper’s General Partner by its
affiliates. Viper’s General Partner is entitled to determine the expenses that are allocable to Viper. For each of the year ended December 31, 2019 and 2018,
Viper’s General Partner allocated $3 million and $2 million, respectively, to Viper.

Tax Sharing

In connection with the closing of the Viper Offering, Viper entered into a tax sharing agreement with Diamondback, dated June 23, 2014, pursuant to
which Viper agreed to reimburse Diamondback for its share of state and local income and other taxes for which Viper’s results are included in a consolidated
tax return filed by Diamondback with respect to taxable periods including or beginning on June 23, 2014. The amount of any such reimbursement is limited
to  the  tax  Viper  would  have  paid  had  it  not  been  included  in  a  combined  group  with  Diamondback.  Diamondback  may  use  its  tax  attributes  to  cause  its
consolidated group, of which Viper may be a member for this purpose, to owe less or no tax. In such a situation, Viper agreed to reimburse Diamondback for
the tax Viper would have owed had the tax attributes not been available or used for Viper’s benefit, even

F-24

though Diamondback had no cash tax expense for that period. For the year ended December 31, 2019, Viper did not accrue any state income tax expense. For
the year ended December 31, 2018, Viper accrued a minimal amount for its share of Texas margin tax for which Viper’s results are included in a combined tax
return filed by Diamondback.

5.    RATTLER MIDSTREAM LP

Rattler  is  a  publicly  traded  Delaware  limited  partnership,  the  common  units  of  which  are  listed  on  the  Nasdaq  Global  Select  Market  under  the
symbol “RTLR”. Rattler was formed by Diamondback in July 2018 to own, operate, develop and acquire midstream infrastructure assets in the Midland and
Delaware Basins of the Permian Basin. Rattler’s General Partner, a wholly-owned subsidiary of Diamondback, serves as the general partner of Rattler. As of
December 31, 2019, Diamondback owned approximately 71% of Rattler’s total units outstanding.

Prior to the completion of Rattler’s initial public offering (the “Rattler Offering”) in May of 2019, Diamondback owned all of the general and limited
partner interests in Rattler. The Rattler Offering consisted of 43,700,000 common units representing approximately 29%  of  the  limited  partner  interests  in
Rattler  at  a  price  to  the  public  of  $17.50  per  common  unit,  which  included  5,700,000  common  units  issued  pursuant  to  an  option  to  purchase  additional
common units granted to the underwriters on the same terms which closed on May 30, 2019. Rattler received net proceeds of approximately $720 million
from the sale of these common units, after deducting offering expenses and underwriting discounts and commissions.

In connection with the completion of the Rattler Offering, Rattler (i) issued 107,815,152 Class B Units representing an aggregate 71% voting limited
partner  interest  in  Rattler  in  exchange  for  a  $1 million  cash  contribution  from  Diamondback,  (ii)  issued  a  general  partner  interest  in  Rattler  to  Rattler’s
General  Partner,  in  exchange  for  a  $1  million  cash  contribution  from  Rattler’s  General  Partner,  and  (iii)  caused  Rattler  LLC  to  make  a  distribution  of
approximately $727 million to Diamondback. Diamondback, as the holder of the Class B units, and Rattler’s General Partner, as the holder of the general
partner interest, are entitled to receive cash preferred distributions equal to 8% per annum on the outstanding amount of their respective $1 million capital
contributions, payable quarterly.

Diamondback has also entered into the following agreements with Rattler:

reimburse  Rattler’s  General  Partner  for  all  direct  and  indirect  expenses  incurred  or  paid  on  Rattler’s  behalf  and  all  other  expenses  allocable  to  Rattler  or
otherwise incurred by Rattler’s General Partner in connection with operating Rattler’s business. The Rattler Partnership Agreement does not set a limit on the

The  Company  uses  the  full  cost  method  of  accounting  for  its  oil  and  natural  gas  properties.  Under  this  method,  all  acquisition,  exploration  and
development costs, including certain internal costs, are capitalized and amortized on a composite unit of production method based on proved oil, natural gas
liquids  and  natural  gas  reserves.  Internal  costs  capitalized  to  the  full  cost  pool  represent  management’s  estimate  of  costs  incurred  directly  related  to
exploration  and  development  activities  such  as  geological  and  other  administrative  costs  associated  with  overseeing  the  exploration  and  development
activities. Costs, including related employee costs, associated with production and operation of the properties are charged to expense as incurred. All other
internal costs not directly associated with exploration and development activities are charged to expense as they are incurred. Capitalized internal costs were
approximately  $49  million,  $29  million  and  $22  million  for  the  years  ended  December  31,  2019,  2018  and  2017,  respectively.  Costs  associated  with
unevaluated properties are excluded from the full cost pool until the Company has made a determination as to the existence of proved reserves. The inclusion
of the Company’s unevaluated costs into the amortization base is expected to be completed within three to five years. Acquisition costs not currently being
amortized  are  primarily  related  to  unproved  acreage  that  the  Company  plans  to  prove  up  through  drilling.  The  Company  has  no  plans  to  let  any  acreage
expire. Sales of oil and natural gas properties, whether or not being amortized currently, are accounted for as adjustments of capitalized costs, with no gain or
loss recognized, unless such adjustments would significantly alter the relationship between capitalized costs and proved reserves of oil, natural gas liquids and
natural gas.

Under this method of accounting, the Company is required to perform a ceiling test each quarter. The test determines a limit, or ceiling, on the book
value of the proved oil and natural gas properties. Net capitalized costs are limited to the lower of unamortized cost net of deferred income taxes, or the cost
center ceiling. The cost center ceiling is defined as the sum of (a) estimated future net revenues, discounted at 10% per annum, from proved reserves, based
on  the  trailing  12-month  unweighted  average  of  the  first-day-of-the-month  price,  adjusted  for  any  contract  provisions,  and  excluding  the  estimated
abandonment costs for properties with asset retirement obligations recorded on the balance sheet, (b) the cost of properties not being amortized, if any, and (c)
the lower of cost or market value of unproved properties included in the cost being amortized, including related deferred taxes for differences between the
book and tax basis of the oil and natural gas properties. If the net book value, including related deferred taxes, exceeds the ceiling, an impairment or non-cash
writedown is required.

Diamondback Energy, Inc. and Subsidiaries
Notes to Consolidated Financial Statements-(Continued)

As  a  result  of  the  decline  in  commodity  prices  during  2019,  the  Company  recorded  a  non-cash  ceiling  test  impairment  for  the  year  ended
December 31, 2019 of $790 million which was included in accumulated depletion. The impairment charge affected the Company’s reported net income but
did not reduce its cash flow. In addition to commodity prices, the Company’s production rates, levels of proved reserves, future development costs, transfers
of  unevaluated  properties  and  other  factors  will  determine  its  actual  ceiling  test  calculation  and  impairment  analysis  in  future  periods.  No  impairment  on
proved oil and natural gas properties was recorded for the year ended December 31, 2018.

At December  31,  2019,  there  was  $228 million  in  exploration  costs  and  development  costs  and  $118  million  in  capitalized  interest  that  are  not
subject to depletion. At December 31, 2018, there were $68 million exploration costs and development costs and $55 million capitalized interest that are not
subject to depletion.

The Company’s asset retirement obligations primarily relate to the future plugging and abandonment of wells and related facilities. The Company
estimates  the  future  plugging  and  abandonment  costs  of  wells,  the  ultimate  productive  life  of  the  properties,  a  risk-adjusted  discount  rate  and  an  inflation
factor in order to determine the current present value of this obligation. To the extent future revisions to these assumptions impact the present value of the
existing asset retirement obligation liability, a corresponding adjustment is made to the oil and natural gas property balance.

In October 2014, the Company acquired a 25% interest in HMW Fluid Management LLC (“HMW LLC”), which was formed to develop, own and
operate  an  integrated  water  management  system  to  gather,  store,  process,  treat,  distribute  and  dispose  of  water  to  exploration  and  production  companies
operating in Midland, Martin and Andrews Counties, Texas.

On June 30, 2018, HMW LLC’s operating agreement was amended. As a result of the amendment, Rattler no longer recognizes an equity investment
in HMW LLC but instead consolidates its undivided interest in the produced water disposal (“PWD”) assets owned by HMW LLC. In exchange for Rattler’s
25% investment, Rattler received a 50% undivided ownership interest in two of the four PWD wells and associated assets previously owned by HMW LLC.
Rattler’s basis in the assets is equivalent to its basis in the equity investment in HMW LLC.

On February 1, 2019, Rattler LLC acquired a 10% equity interest in EPIC Crude Holdings, LP (“EPIC”), which is building a pipeline (the “EPIC
project”) that, once fully operational, will transport crude and NGL across Texas for delivery into the Corpus Christi market. The EPIC project began initial
operations during the third quarter of 2019.

On February 15, 2019, Rattler LLC acquired a 10% equity interest in Gray Oak Pipeline, LLC (“Gray Oak”), which is building a pipeline (the “Gray
Oak project”) that, once operational, will transport crude from the Permian to Corpus Christi on the Texas Gulf Coast. The Gray Oak project began initial
operations during the fourth quarter of 2019.

On March 29, 2019, Rattler LLC executed a short-term promissory note to Gray Oak. The note allows for borrowing by Gray Oak of up to $123
million at 2.52% interest rate with a maturity date of March 31, 2022. During the year ended December 31, 2019, there were $23 million in borrowings and
repayments under this note. The short-term promissory note was repaid on May 31, 2019.

On June 4, 2019, Rattler entered into an equity contribution agreement with respect to Gray Oak. The equity contribution agreement requires Rattler
to contribute equity or make loans to Gray Oak so that Gray Oak can, to the extent necessary, cure payment defaults under Gray Oak’s credit agreement and,
in certain instances, repay Gray Oak’s credit agreement in full. Rattler’s obligations under the equity contribution agreement are limited to its proportionate
ownership interest in Gray Oak, and such obligations are guaranteed by Rattler LLC, Tall City, Rattler OMOG LLC and Rattler Ajax Processing LLC.

On July 30, 2019, Rattler LLC joined Wink to Webster Pipeline LLC as a 4% member, together with affiliates of ExxonMobil, Plains All American
Pipeline,  Delek  US,  MPLX  LP  and  Lotus  Midstream.  The  joint  venture  is  developing  a  crude  oil  pipeline  with  origin  points  at  Wink  and  Midland  in  the
Permian Basin for delivery to multiple Houston area locations (the “Wink to Webster project”). The Wink to Webster project is expected to begin service in
the first half of 2021.

On October 1, 2019, Rattler LLC acquired a 60% equity interest in OMOG JV LLC (“OMOG”). On November 7, 2019, OMOG acquired 100% of
Reliance Gathering, LLC which operates a crude oil gathering system in the Permian, and was renamed as Oryx Midland Oil Gathering LLC following the
acquisition.  While  Rattler’s  equity  interest  is  60%,  the  investment  is  accounted  for  as  an  equity  method  investment  as  Rattler  does  not  control  operating
activities and substantive participating rights exist with the controlling minority investor.

On December 20, 2019, Rattler LLC acquired a 50% equity interest in Amarillo Rattler LLC, which currently owns and operates the Yellow Rose
gas  gathering  and  processing  system  with  estimated  total  processing  capacity  of  40,000  Mcf/d  and  over  84  miles  of  gathering  and  regional  transportation
pipelines in Dawson, Martin and Andrews Counties, Texas. This joint

venture also intends to construct and operate a new 60,000  Mcf/d  cryogenic  natural  gas  processing  plant  in  Martin  County,  Texas.  While  Rattler’s  equity
interest is 50%, the investment is accounted for as an equity method investment as Rattler does not control operating activities and substantive participating
rights exist with the controlling investor.

No impairments were recorded for Rattler’s equity method investments for the year ended December 31, 2019 or 2018.

At December 31, 2019, there was $1 million of capitalized interest that was related to equity method investments that have not yet begun operations.

offering expenses, but disregarding accrued interest, from the issuance of the new 4.750% senior notes. The Company used a portion of the net proceeds from
the issuance of the new 4.750% senior notes to repay a portion of the outstanding borrowings its revolving credit facility and the balance for general corporate
purposes, including funding a portion of the cash consideration for the acquisition of certain assets from Ajax Resources, LLC..

On December 20, 2019, the Company redeemed all of the outstanding 4.750% senior notes. The redemption payment (the “Redemption Payment”)
included $1.25 billion  of  outstanding  principal  at  a  redemption  price  of  103.563%  of  the  principal  amount  of  the  4.750%  senior  notes,  plus  accrued  and
unpaid interest on the outstanding principal amount to the Redemption

Date. On December 5, 2019, the indenture governing the 4.750% senior notes was fully satisfied and discharged and the guarantors were released from their
guarantees of the 4.750% senior notes. The Company funded the Redemption Payment with a portion of the net proceeds from the issuance of the December
2019 Notes.

The 4.750% senior notes bore interest at a rate of 4.750% per annum, payable semi-annually, in arrears on May 1 and November 1 of each year,
commencing on May 1, 2017 and would have matured on November 1, 2024. All of our restricted subsidiaries that guaranteed our revolving credit facility

the initial purchaser’s discount and the Company’s estimated offering expenses, but disregarding accrued interest, from the issuance of the new 2025 notes.
The  Company  used  the  net  proceeds  from  the  issuance  of  the  new  2025  notes  to  repay  a  portion  of  the  outstanding  borrowings  under  its  revolving  credit
facility.

The 2025 senior notes bear interest at a rate of 5.375% per annum, payable semi-annually, in arrears on May 31 and November 30 of each year and
will mature on May 31, 2025. All of the Company’s existing and future restricted subsidiaries that guarantee its revolving credit facility guarantee the 2025
senior notes. Currently, the 2025 senior notes are not guaranteed by any of the Company’s subsidiaries other than Diamondback O&G LLC and will not be
guaranteed by any of the Company’s future unrestricted subsidiaries.

The Company may on any one or more occasions redeem some or all of the 2025 senior notes at any time on or after May 31, 2020 at the redemption

occasions redeem all or a portion of the 2025 senior notes at a price equal to 100% of the principal amount of the 2025 senior notes plus a “make-whole”
premium  and  accrued  and  unpaid  interest  to  the  redemption  date.  In  addition,  any  time  prior  to  May  31,  2020,  the  Company  may  on  any  one  or  more
occasions redeem the 2025 senior notes in an aggregate principal amount not to exceed 35% of the aggregate principal amount of the 2025 senior notes issued

from certain equity offerings.

redemption price set forth in the indenture governing the December 2019 Notes. If the December 2019 Notes are redeemed on or after their respective par call
dates, in each case, such December 2019 Notes will be redeemed at a redemption price equal to 100% of the principal amount of the December 2019 Notes to
be redeemed plus interest accrued thereon to but not including the redemption date.

Upon  the  occurrence  of  a  Change  of  Control  Triggering  Event  (as  defined  in  the  indenture  governing  the  December  2019  Notes),  holders  may

ability of certain of its subsidiaries to incur liens securing funded indebtedness and on the Company’s ability to consolidate, merge or sell, convey, transfer or
lease all or substantially all of its assets.

Second Amended and Restated Credit Facility

The Company and Diamondback O&G LLC, as borrower, entered into the second amended and restated credit agreement, dated November 1, 2013,
as amended, with a syndicate of banks, including Wells Fargo, as administrative agent, and its affiliate Wells Fargo Securities, LLC, as sole book runner and
lead arranger. On June 28, 2019, the credit agreement was amended pursuant to an eleventh amendment, which implemented certain changes to the credit
facility  for  the  period  on  and  after  the  date  on  which  our  unsecured  debt  achieves  an  investment  grade  rating  from  two  rating  agencies  and  certain  other
conditions  in  the  credit  agreement  are  satisfied  (the  “investment  grade  changeover  date”).  On  November  20,  2019,  Diamondback  O&G  LLC  caused
Diamondback  O&G  LLC  to  deliver  a  notice  as  borrower  under  the  revolving  credit  facility  to  trigger  the  “investment  grade  changeover  date.”  As  of
December  31,  2019,  the  maximum  credit  amount  available  under  the  credit  agreement  is  $2.0  billion.  As  of  December  31,  2019,  the  Company  had
approximately $13 million of outstanding borrowings under its revolving credit facility and $1.99 billion available for future borrowings under the revolving
credit facility.

Diamondback  O&G  LLC  is  the  borrower  under  the  credit  agreement,  and,  as  of  December  31,  2019,  the  credit  agreement  is  guaranteed  by
Diamondback Energy, Inc. None of the Company’s other subsidiaries are guarantors under the revolving credit facility. On December 5, 2019, Diamondback
O&G  LLC  delivered  a  letter  notifying  the  administrative  agent  under  the  credit  agreement  that  as  of  such  date,  each  of  the  guarantors,  other  than
Diamondback Energy, Inc., ceased to be a guarantor under the credit agreement.

The outstanding borrowings under the credit agreement bear interest at a per annum rate elected by us that is equal to the alternate base rate (which is
equal to the greatest of the prime rate, the Federal Funds effective rate plus 0.5%, and 3 month LIBOR plus 1.0%) or LIBOR, in each case plus the applicable
margin.  The  applicable  margin  with  range  from  0.125%  to  1.0%  per  annum  and  from  1.125%  to  2.0%  per  annum  in  the  case  of  LIBOR,  in  each  case,
depending on the pricing level, which in turn depends on the rating agencies’ rating of our unsecured debt. We are obligated to pay a quarterly commitment
fee  ranging  from  0.125%  to  0.350%  per  year  on  the  unused  portion  of  the  commitment,  based  on  the  pricing  level,  which  in  turn  depends  on  the  rating
agencies’ rating of our unsecured debt.

Loan principal may be optionally repaid from time to time without premium or penalty (other than customary LIBOR breakage). Loan principal is
required to be repaid (a) to the extent the loan amount exceeds the commitment due to any termination or reduction of the aggregate maximum credit amount
and (b) at the maturity date of November 1, 2022.

The  credit  agreement  contains  a  financial  covenant  that  requires  us  to  maintain  a  Total  Net  Debt  to  Capitalization  Ratio  (as  defined  in  the  credit
agreement) of no more than 65%. Our non-guarantor restricted subsidiaries may incur debt for borrowed money in an aggregate principal amount up to 15%
of consolidated net tangible assets (as defined in the credit agreement) and we and our restricted subsidiaries may incur liens if the aggregate amount of debt
secured by such liens does not exceed 15% of consolidated net tangible assets.

As of December 31, 2019 and 2018, the Company was in compliance with all financial covenants under the revolving credit facility, as then in effect.
The lenders may accelerate all of the indebtedness under the revolving credit facility upon the occurrence and during the continuance of any event of default.
The credit agreement contains customary events of default, including non-payment, breach of covenants, materially incorrect representations, cross-default,
bankruptcy and change of control. There are no cure periods for events of default due to non-payment of principal and breaches of negative and financial
covenants, but non-payment of interest and breaches of certain affirmative covenants are subject to customary cure periods.

Diamondback Energy, Inc. and Subsidiaries
Notes to Consolidated Financial Statements-(Continued)

At  the  effective  time  of  the  Merger,  Energen  became  the  Company’s  wholly  owned  subsidiary  and  remained  the  issuer  of  an  aggregate  principal
amount of $530 million  in  notes  (the  “Energen  Notes”),  issued  under  an  indenture  dated  September  1,  1996  with  The  Bank  of  New  York  as  Trustee  (the
“Energen Indenture”). As of December 31, 2019, the Energen Notes consist of: (1) $399 million aggregate principal amount of 4.625% senior notes due on
September 1, 2021, (2) $108 million of 7.125% notes due on February 15, 2028, (3) $21 million of 7.32% notes due on July 28, 2022, and (4) $11 million of
7.35% notes due on July 28, 2027.

sole issuer and obligor under the Energen Notes. The Energen Notes rank equally in right of payment with all other senior unsecured indebtedness of Energen
if any, and are effectively subordinated to Energen’s senior secured indebtedness, if any, to the extent of the value of the collateral securing such indebtedness.
Neither we nor any of our subsidiaries guarantee the Energen Notes.

The Energen Indenture contains certain covenants that, subject to certain exceptions and qualifications, limit Energen’s ability to incur or suffer to
exist liens, to enter into sale and leaseback transactions, to consolidate with or merge into any other entity, and to convey, transfer or lease its properties and
assets substantially as an entirety to any person or entity.  The Energen Indenture not include a restriction on the payment of dividends.

On November 29, 2018, Energen guaranteed the Company’s indebtedness under its credit facility and granted a lien on certain of its assets to secure
such indebtedness, and on December 21, 2018, Energen’s subsidiaries guaranteed the Company’s indebtedness under its credit agreement and granted liens on
certain of their assets to secure such indebtedness. As a result of such guarantees, under the terms of and the 2025 Indenture, Energen is also a guarantor of
the 2025 Senior Notes.

Viper’s Facility - Wells Fargo Bank

On  July  20,  2018,  Viper  LLC,  as  borrower,  entered  into  an  amended  and  restated  credit  agreement  with  Viper,  as  guarantor,  Wells  Fargo,  as
administrative agent, and the other lenders. The credit agreement, as amended (the “Viper credit agreement”), provides for a revolving credit facility in the
maximum credit amount of $2 billion and a borrowing base based on Viper LLC’s oil and natural gas reserves and other factors (the “borrowing base”) of
$775 million,  subject  to  scheduled  semi-annual  and  other  elective  borrowing  base  redeterminations.  The  borrowing  base  is  scheduled  to  be  re-determined
semi-annually  with  effective  dates  of  May  1st  and  November  1st.  In  addition,  Viper  LLC  and  Wells  Fargo  each  may  request  up  to  three  interim
redeterminations of the borrowing base during any 12-month period. In connection with Viper’s fall redetermination in November 2019, the borrowing base
under the Viper credit agreement was increased to $775 million. As of December 31, 2019, the borrowing base was set at $775 million, and Viper LLC had
$97 million of outstanding borrowings and $678 million available for future borrowings under the Viper credit agreement.

The outstanding borrowings under the Viper credit agreement bear interest at a per annum rate elected by Viper LLC that is equal to an alternate base
rate (which is equal to the greatest of the prime rate, the Federal Funds effective rate plus 0.5% and 3-month LIBOR plus 1.0%) or LIBOR, in each case plus
the applicable margin. The applicable margin ranges from 0.75% to 1.75% per annum in the case of the alternate base rate and from 1.75% to 2.75%  per
annum in the case of LIBOR, in each case depending on the amount of loans and letters of credit outstanding in relation to the commitment, which is defined
as  the  lesser  of  the  maximum  credit  amount  and  the  borrowing  base.  Viper  LLC  is  obligated  to  pay  a  quarterly  commitment  fee  ranging  from  0.375% to
0.500% per year on the unused portion of the commitment, which fee is also dependent on the amount of loans and letters of credit outstanding in relation to
the commitment. Loan principal may be optionally repaid from time to time without premium or penalty (other than customary LIBOR breakage), and is
required to be repaid (i) to the extent the loan amount exceeds the commitment or the borrowing base, whether due to a borrowing base redetermination or
otherwise  (in  some  cases  subject  to  a  cure  period),  (ii)  in  an  amount  equal  to  the  net  cash  proceeds  from  the  sale  of  property  when  a  borrowing  base
deficiency or event of default exists under the credit agreement and (iii) at the maturity date of November 1, 2022. The loan is secured by substantially all of
the assets of Viper and Viper LLC.

Viper’s Notes

On  October  16,  2019,  Viper  completed  an  offering  in  which  it  issued  its  5.375%  Senior  Notes  due  2027  in  aggregate  principal  amount  of  $500
million  (the  “Viper  Notes”).  Viper  received  gross  proceeds  of  $500  million  from  the  such  offering,  which  it  loaned  to  Viper  LLC.  Viper  LLC  paid  the
expenses of the offering, resulting in net proceeds of the offering of $490 million, which Viper LLC used to pay down borrowings under the Viper credit
agreement.

The Viper Notes were issued under an indenture, dated as of October 16, 2019, among Viper, as issuer, Viper LLC, as guarantor and Wells Fargo, as
trustee (the “Viper Indenture”). Pursuant to the Viper Indenture and the Viper Notes, interest on the Viper Notes accrues at a rate of 5.375% per annum on the

ability of its restricted subsidiaries to incur or guarantee additional indebtedness or issue certain redeemable or preferred equity, make certain investments,
declare or pay dividends or make distributions on equity interests or redeem, repurchase or retire equity interests or subordinated indebtedness, transfer or sell
assets, agree to payment restrictions affecting its restricted subsidiaries, consolidate, merge, sell or otherwise dispose of all or substantially all of its assets,

Alliance with Obsidian Resources, L.L.C.

The  Company  entered  into  a  participation  and  development  agreement  (the  “DrillCo  Agreement”),  dated  September  10,  2018,  with  Obsidian
Resources,  L.L.C.  (“CEMOF”)  to  fund  oil  and  natural  gas  development.  Funds  managed  by  CEMOF  and  its  affiliates  have  agreed  to  commit  to  funding
certain costs out of CEMOF’s net production revenue and, for a period of time, to the extent not funded by such revenue, up to an additional $300 million, to
fund  drilling  programs  on  locations  provided  by  the  Company.  Subject  to  adjustments  depending  on  asset  characteristics  and  return  expectations  of  the
selected drilling plan, CEMOF will fund up to 85% of the costs associated with new wells drilled under the DrillCo Agreement and is expected to receive an
80% working interest in these wells until it reaches certain payout thresholds equal to a cumulative 9% and then 13% internal rate of return. Upon reaching
the final internal rate of return target, CEMOF’s interest will be reduced to 15%, while the Company’s interest will increase to 85%. As of December 31,
2019, CEMOF had funded approximately $36 million. As of December 31, 2019, eleven joint wells have been drilled and completed.

Earnings Per Share

The  Company’s  basic  earnings  per  share  amounts  have  been  computed  based  on  the  weighted-average  number  of  shares  of  common  stock
outstanding for the period. Diluted earnings per share include the effect of potentially dilutive shares outstanding for the period. Additionally, for the diluted
earnings per share computation, the per share earnings of Viper are included in the consolidated earnings per share computation based on the consolidated
group’s holdings of the subsidiary.

A reconciliation of the components of basic and diluted earnings per common share is presented in the table below:

12.    EQUITY-BASED COMPENSATION

On  October  10,  2012,  the  Board  of  Directors  approved  the  Diamondback  Energy,  Inc.  2012  Equity  Incentive  Plan  (the  “2012  Plan”),  which  is
intended to provide eligible employees with equity-based incentives. The 2012 Plan provides for the granting of incentive stock options, nonstatutory stock
options, restricted awards (restricted stock and restricted stock units), performance awards, and stock appreciation rights, or any combination of the foregoing.
A total of 1,313,588 shares of the Company’s common stock has been reserved for issuance pursuant to this plan.

The following table presents the effects of the equity and stock based compensation plans and related costs:

Restricted Stock Units

Under the Equity Plan, approved by the Board of Directors, the Company is authorized to issue restricted stock and restricted stock units to eligible
employees. The Company estimates the fair values of restricted stock awards and units as the closing price of the Company’s common stock on the grant date
of the award, which is expensed over the applicable vesting period.

The following table presents the Company’s restricted stock units activity under the Equity Plan during the year ended December 31, 2019:

The aggregate fair value of restricted stock units that vested during the years ended December 31, 2019, 2018 and 2017 was $45 million, $19 million
and $15 million, respectively. As of December 31, 2019, the Company’s unrecognized compensation cost related to unvested restricted stock awards and units
was $38 million. Such cost is expected to be recognized over a weighted-average period of 2.2 years.

Performance-Based Restricted Stock Units

To provide long-term incentives for the executive officers to deliver competitive returns to the Company’s stockholders, the Company has granted
performance-based restricted stock units to eligible employees. The ultimate number of shares awarded from these conditional restricted stock units is based
upon  measurement  of  total  stockholder  return  of  the  Company’s  common  stock  (“TSR”)  as  compared  to  a  designated  peer  group  during  a  three-year
performance period.

In February 2017, eligible employees received performance restricted stock unit awards totaling 37,440 units from which a minimum of 0% and a
maximum of 200% units could be awarded. The awards have a performance period of January 1, 2017 to December 31, 2018 and vested at December 31,
2018. Eligible employees received additional performance restricted stock unit awards totaling 74,880 units from which a minimum of 0% and a maximum of
200% units could be awarded. The awards have a performance period of January 1, 2017 to December 31, 2019 and vested at December 31, 2019.

In February 2018, eligible employees received performance restricted stock unit awards totaling 117,423 units from which a minimum of 0% and a
maximum of 200% units could be awarded. The awards have a performance period of January 1, 2018 to December 31, 2020 and cliff vest at December 31,
2020.

In March 2019, eligible employees received performance restricted stock unit awards totaling 199,723 units from which a minimum of 0%  and  a
maximum of 200% units could be awarded. The awards have a performance period of January 1, 2019 to December 31, 2021 and cliff vest at December 31,
2021.  In  March  2019,  eligible  employees  received  performance  restricted  stock  unit  awards  totaling  32,958  units  from  which  a  minimum  of  0%  and  a
maximum  of  200%  units  could  be  awarded.  The  awards  have  a  performance  period  of  January  1,  2019  to  December  31,  2021  and  vest  in  five  equal
installments beginning on March 1, 2025.

The fair value of each performance restricted stock unit is estimated at the date of grant using a Monte Carlo simulation, which results in an expected

percentage of units to be earned during the performance period.

Stock Appreciation Rights

In  connection  with  the  Energen  merger,  each  outstanding  stock  appreciation  right  in  respect  of  Energen  common  stock  that  was  outstanding
immediately prior to the effective time of the merger was converted into a fully vested stock appreciation right in respect of (i) that number of whole shares of
Diamondback common stock (rounded down to the nearest whole share) equal to the product of (A) the total number of shares of Energen common stock
subject to such stock appreciation right immediately prior to the effective time of the merger multiplied by (B) the exchange ratio, (ii) at an exercise price per
share of Diamondback common stock (rounded up to the nearest whole cent) equal to the quotient of (A) the exercise price per share of Energen common
stock of such stock appreciation right immediately prior to the effective time of the merger divided by (B) the exchange ratio. These awards have a three-year
requisite service period.

In  connection  with  the  Energen  Merger,  each  option  to  purchase  shares  of  Energen  common  stock  that  was  outstanding  immediately  prior  to  the
effective time of the merger was converted into a fully vested option to purchase (i) that number of whole shares of Diamondback common stock (rounded
down to the nearest whole share) equal to the product of (A) the total number of shares of Energen common stock subject to such option immediately prior to
the effective time of the merger multiplied by (B) the exchange ratio, (ii) at an exercise price per share of Diamondback common stock (rounded up to the
nearest whole cent) equal to the quotient of (A) the exercise price per share of Energen common stock of such option immediately prior to the effective time
divided by (B) the exchange ratio. The exercise price of stock options granted may not be less than the market value of the stock at the date of grant.

The Company estimates the fair values of stock options granted using a Black-Scholes option valuation model, which requires the Company to make
several assumptions. The expected term of options granted was determined based on the contractual term of the awards at effective time of the merger. The
risk-free interest rate is based on the U.S. treasury yield curve rate for the expected term of the option at the date of grant. All such amounts represent the
weighted-average amounts for each year.

On June 17, 2014, in connection with the Viper Offering, the Board of Directors of the General Partner adopted the Viper Energy Partners LP Long
Term Incentive Plan (“Viper LTIP”), effective June 17, 2014, for employees, officers, consultants and directors of the General Partner and any of its affiliates,
including Diamondback, who perform services for Viper. The Viper LTIP provides for the grant of unit options, unit appreciation rights, restricted units, unit
awards, phantom units, distribution equivalent rights, cash awards, performance awards, other unit-based awards and substitute awards. A total of 8,892,918
common units has been reserved for issuance pursuant to the Viper LTIP. Common units that are cancelled, forfeited or withheld to satisfy exercise prices or
tax withholding obligations will be available for delivery pursuant to other awards. The Viper LTIP is administered by the Board of Directors of the General
Partner or a committee thereof.

Under the Viper LTIP, the Board of Directors of Viper’s General Partner is authorized to issue phantom units to eligible employees. Viper estimates
the fair value of phantom units as the closing price of Viper’s common units on the grant date of the award, which is expensed over the applicable vesting
period. Upon vesting the phantom units entitle the recipient one common unit of Viper for each phantom unit.

14.    INCOME TAXES

Deferred  income  taxes  reflect  the  net  tax  effects  of  temporary  differences  between  the  carrying  amounts  of  assets  and  liabilities  for  financial
reporting  purposes  and  the  amounts  used  for  income  tax  purposes.  The  Company  is  subject  to  corporate  income  taxes  and  the  Texas  margin  tax.  The
Company and its subsidiaries, other than Viper, Viper LLC, Rattler and Rattler LLC, file a federal corporate income tax return on a consolidated basis. As
discussed further below, Viper is a taxable entity for federal income tax purposes effective May 10, 2018, and as such files a federal corporate income tax
return including the activity of its investment in Viper LLC. Subsequent to Rattler’s election to be treated as a corporation for federal income tax purposes
effective May 24, 2019, Rattler is also a taxable entity and as such files a federal corporate income tax return including the activity of its investment in Rattler
LLC. Viper’s and Rattler’s provision for income taxes is included in the Company’s consolidated income tax provision and, to the extent applicable, in net
income attributable to the non-controlling interest.

The Tax Cuts and Jobs Act, a historic reform of the U.S. federal income tax statutes, was enacted on December 22, 2017. As of the completion of the
Company’s  financial  statements  for  the  year  ended  December  31,  2017,  the  Company  had  substantially  completed  its  accounting  for  the  effects  of  the
enactment  of  the  Tax  Cuts  and  Jobs  Act  and  with  respect  to  those  items  for  which  the  Company’s  accounting  was  not  complete,  the  Company  made
reasonable estimates of the effects on its deferred tax balances.

To account for the effects of the Tax Cut and Jobs Act, the Company remeasured its deferred tax assets and liabilities based on the federal income
and state income tax rates at which they expected to reverse, which is generally a federal income tax rate of 21%. The enacted rate change resulted in a non-
cash decrease of approximately $68 million to the Company’s income tax provision for the period ended December 31, 2017 and a corresponding reduction to
the Company’s net noncurrent deferred tax liability balance as of December 31, 2017. At December 31, 2018, the Company completed its accounting for all
of the enactment-date income tax effects of the Tax Cuts and Jobs Act and did not made any adjustments to the provisional amounts recorded December 31,
2017.

The Company’s effective income tax rates were 13.0% and 15.1% for the years ended December 31, 2019 and 2018, respectively. Total income tax
expense for the year ended December 31, 2019 differed from amounts computed by applying the United States federal statutory tax rate to pre-tax income for
the period primarily due to the revision of estimated deferred taxes recognized as a result of Viper’s change in tax status, and state income taxes net of federal
benefit. Total income tax expense for the year ended December 31, 2018 differed from amounts computed by applying the United States federal statutory rate
to pre-tax income for the period primarily due to the impact of deferred taxes recognized as a result of Viper’s change in tax status, net income attributable to
the noncontrolling interest, and state income taxes net of federal benefit.

The Company had net deferred tax liabilities of approximately $1.7 billion at December 31, 2019 and 2018. On November 29, 2018, the Company
completed its acquisition of Energen. For federal income tax purposes, the acquisition was a tax-free merger whereby the Company’s tax basis in Energen
assets and liabilities was unaffected by the acquisition. As of December 31, 2018, the Company recorded a deferred tax liability of $1.4 billion  associated
with  the  acquired  assets,  which  includes  deferred  tax  assets  related  to  tax  attributes  acquired  from  Energen.  As  of  December  31,  2019,  the  Company  has
completed its purchase price allocation for the acquisition, including an increase of $23 million to the deferred tax liability as a result of adjustments to fair
value of the acquired assets.

The Company incurred a tax net operating loss ("NOL") in the current year due principally to the ability to expense certain intangible drilling and
development  costs  under  current  law.  There  is  no  tax  refund  available  to  the  Company  as  a  result  of  its  loss,  nor  is  there  any  current  federal  income  tax
payable. At December 31, 2019, the Company had approximately $400 million of federal NOLs expiring in 2032 through 2037 and $1.3 billion of federal
NOLs with an indefinite carryforward life, including NOLs acquired from Energen. The Company principally operates in the state of Texas and is subject to
Texas Margin Tax, which currently does not include an NOL carryover provision. The Company’s federal tax attributes acquired from Energen are subject to
an annual limitation under Section 382 of the Internal Revenue Code of 1986, as amended, which relates to tax attribute limitations upon the 50% or greater
change of ownership of an entity during any three-year look back period. The Company believes that the application of Section 382 will not have an adverse
effect  on  future  usage  of  the  Company’s  NOLs  and  credits,  including  federal  tax  attributes  acquired  from  Energen.  The  Company’s  minimum  tax  credits,
including those acquired from Energen, are classified as $19 million current and $19 million noncurrent income tax receivables on the balance sheet.

As of December 31, 2019,  the  Company  has  a  valuation  allowance  of  $7 million  primarily  related  to  certain  state  NOL  carryforwards  which  the
Company  does  not  believe  are  realizable  as  it  does  not  anticipate  future  operations  in  those  states.  Management’s  assessment  at  each  balance  sheet  date
included  consideration  of  all  available  positive  and  negative  evidence  including  the  anticipated  timing  of  reversal  of  deferred  tax  liabilities.  Management
believes that the balance of the Company’s NOLs are realizable to the extent of future taxable income primarily related to the excess of book carrying value
of properties over their respective tax bases. As of December 31, 2019, management determined that it is more likely than not that the Company will realize
its remaining deferred tax assets.

As discussed further in Note 4—Viper Energy Partners LP, on March 29, 2018, Viper announced that the Board of Directors of its General Partner

had unanimously approved a change of Viper’s federal income tax status from that of a pass-

F-43

 
 
 
 
 
   
 
   
Table of Contents

Notes to Consolidated Financial Statements-(Continued)

through partnership to that of a taxable entity, which change became effective on May 10, 2018. The transactions undertaken in connection with the change in
Viper’s  tax  status  were  not  taxable  to  the  Company.  Subsequent  to  Viper’s  change  in  tax  status,  Viper’s  provision  for  income  taxes  for  the  periods  ended
December 31, 2018 and 2019 are based on its estimated annual effective tax rate plus discrete items. As such, Viper’s provision for income taxes is included
in the Company’s consolidated financial statements and to the extent applicable, in net income attributable to the non-controlling interest.

At December  31,  2019,  the  Company’s  net  deferred  tax  liabilities  include  a  deferred  tax  asset  of  approximately  $134  million  related  to  Viper’s
investment in Viper LLC, approximately $115 million of which was recorded as a result of Viper’s change in tax status. Under federal income tax provisions
applicable to Viper’s change in tax status, Viper’s basis for federal income tax purposes in its interest in Viper LLC consisted primarily of the sum of Viper’s
unitholders’  tax  bases  in  their  interests  in  Viper  on  the  date  of  the  tax  status  change.  Viper  prepared  its  best  estimate  of  the  tax  basis  in  Viper  LLC  for
purposes of Viper’s income tax provision for the period of the change, but information necessary for Viper to finalize its determination was not available until
unitholders’ tax basis information was fully reported and Viper finalized its federal income tax computations for 2018. Based on such finalized information as
of the third quarter 2019, Viper revised its estimate of the difference between its tax basis and its basis for financial accounting purposes in Viper LLC on the
date of the tax status change, resulting in deferred income tax benefit of $42 million included in the Company’s consolidated income tax provision for the
year ended December 31, 2019. As of December 31, 2019, Viper has federal net operating loss carryforwards of approximately $38 million which may be
carried forward indefinitely to offset future taxable income.

As  discussed  further  in  Note  5—Rattler  Midstream  LP,  on  May  28,  2019,  Rattler  completed  its  initial  public  offering.  Even  though  Rattler  is
organized as a limited partnership under state law, Rattler is subject to U.S. federal and state income tax at corporate rates, subsequent to the effective date of
Rattler’s  election  to  be  treated  as  a  corporation  for  U.S.  federal  income  tax  purposes.  As  such,  Rattler’s  provision  for  income  taxes  is  included  in  the
Company’s consolidated financial statements and to the extent applicable, in net income attributable to the non-controlling interest.

At  December  31,  2019,  the  Company’s  net  deferred  tax  liabilities  include  a  deferred  tax  liability  of  approximately  $8 million  related  to  Rattler’s
investment in Rattler LLC. Subsequent to the deemed formation of Rattler LLC as a partnership for federal income tax purposes upon Rattler’s IPO, deferred
taxes are no longer provided on the underlying assets and liabilities of Rattler LLC but are provided on the difference between Rattler’s basis for financial
accounting purposes and basis for federal income tax purposes in its investment in Rattler LLC. Rattler incurred an NOL in the current year due principally to
Rattler LLC’s tax deductions for accelerated depreciation, which exceeded its other items of taxable income. At December 31, 2019, Rattler has federal net
operating loss carryforwards of approximately $1 million which may be carried forward indefinitely to offset future taxable income.

The Company’s federal and state income tax returns for 2012 through the current tax year remain open and subject to examination by the IRS and
major state taxing jurisdictions. Energen is currently under IRS examination of its federal consolidated income tax returns for 2014 and 2016. Accordingly, it
is reasonably possible that significant changes to the reserve for uncertain tax positions may occur as a result of various audits and the expiration of the statute
of limitations. Although the timing and outcome of tax examinations is highly uncertain, the Company does not expect the change in unrecognized tax benefit
within the next 12 months would have a material impact to the financial statements.

The  Company  is  continuing  its  practice  of  recognizing  interest  and  penalties  related  to  income  tax  matters  as  interest  expense  and  general  and
administrative expenses, respectively. During the years ended December 31, 2019 and 2018, there were no penalties and less than $1 million and $0 million
of interest, respectively, associated with uncertain tax positions recognized in the Company’s consolidated financial statements.

15. DERIVATIVES

All derivative financial instruments are recorded at fair value in the accompanying balance sheet. The Company has not designated its derivative
instruments as hedges for accounting purposes and, as a result, marks its derivative instruments to fair value and recognizes the cash and non-cash changes in
fair value in the consolidated statements of operations under the caption “Gain (loss) on derivative instruments, net.”

Commodity Contracts

The Company has used fixed price swap contracts, fixed price basis swap contracts, double-up swap contracts and three-way costless collars with
corresponding put, short put and call options to reduce price volatility associated with certain of its oil and natural gas sales. With respect to the Company’s
fixed price swap contracts and fixed price basis swap contracts, the counterparty is required to make a payment to the Company if the settlement price for any
settlement period is less than the swap or basis price, and the Company is required to make a payment to the counterparty if the settlement price for any
settlement period is greater than the swap or basis price. The Company has fixed price basis swaps for the spread between the WTI Magellan East Houston oil
price and the WTI Cushing oil price and for the spread between the Henry Hub natural gas price and the Waha Hub natural gas price. The Company also
utilizes double-up swap contracts for a portion of its natural gas sales. These contracts include a traditional fixed price swap in addition to a call option at the
same quantity and price, providing the counterparty the option to double the volume in the swap contract should the monthly settlement price exceed the fixed
price contracted upon.

Under the Company’s costless collar contracts, a three-way collar is a combination of three options: a ceiling call, a floor put, and a short put. The
counterparty is required to make a payment to the Company if the settlement price for any settlement period is less than the ceiling price to a maximum of the
difference between the floor price and the short put price.  The Company is required to make a payment to the counterparty if the settlement price for any
settlement period is greater than the ceiling price. If the settlement price is between the floor and the ceiling price, there is no payment required.

The Company’s derivative contracts are based upon reported settlement prices on commodity exchanges, with crude oil derivative settlements based
on  New  York  Mercantile  Exchange  West  Texas  Intermediate  pricing  (Cushing  and  Magellan  East  Houston)  and  ICE  Brent  pricing,  and  with  natural  gas
derivative  settlements  based  on  the  New  York  Mercantile  Exchange  Henry  Hub  and  Waha  Hub  pricing  and  liquids  derivative  settlements  based  on  Mt.
Belvieu pricing.

By  using  derivative  instruments  to  economically  hedge  exposure  to  changes  in  commodity  prices,  the  Company  exposes  itself  to  credit  risk  and
market risk. Credit risk is the failure of the counterparty to perform under the terms of the derivative contract. When the fair value of a derivative contract is
positive, the counterparty owes the Company, which creates credit risk. The Company’s counterparties are participants in the secured second amended and
restated credit agreement, which is secured by substantially all of the assets of the guarantor subsidiaries; therefore, the Company is not required to post any
collateral. The Company does not require collateral from its counterparties. The Company has entered into derivative instruments only with counterparties
that are also lenders in our credit facility and have been deemed an acceptable credit risk.

The Company has used interest rate swaps and treasury locks to reduce the Company’s exposure to variable rate interest payments associated with
the  Company’s  revolving  credit  facility.  The  interest  rate  swaps  and  treasury  locks  have  not  been  designated  as  hedging  instruments  and  as  a  result,  the
Company recognizes all changes in fair value immediately in earnings. Effective November 2019, the Company terminated all of its interest rate swaps and
treasury locks which resulted in a gain of $43 million, net of fees.

Balance sheet offsetting of derivative assets and liabilities

The fair value of swaps is generally determined using established index prices and other sources which are based upon, among other things, futures
prices  and  time  to  maturity.  These  fair  values  are  recorded  by  netting  asset  and  liability  positions  that  are  with  the  same  counterparty  and  are  subject  to
contractual terms which provide for net settlement.

Fair  value  is  defined  as  the  price  that  would  be  received  to  sell  an  asset  or  paid  to  transfer  a  liability  in  an  orderly  transaction  between  market
participants at the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of
unobservable inputs.

The fair value hierarchy is based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be
used to measure fair value. The Company’s assessment of the significance of a particular input to the fair value measurements requires judgment and may
affect the valuation of the assets and liabilities being measured and their placement within the fair value hierarchy. The Company uses appropriate valuation
techniques based on available inputs to measure the fair values of its assets and liabilities.

Table of Contents

Diamondback Energy, Inc. and Subsidiaries
Notes to Consolidated Financial Statements-(Continued)

Level 1 - Observable inputs that reflect unadjusted quoted prices for identical assets or liabilities in active markets as of the reporting date.

Level 2 - Observable market-based inputs or unobservable inputs that are corroborated by market data. These are inputs other than quoted prices in
active markets included in Level 1, which are either directly or indirectly observable as of the reporting date.

Level  3  -  Unobservable  inputs  that  are  not  corroborated  by  market  data  and  may  be  used  with  internally  developed  methodologies  that  result  in
management’s best estimate of fair value.

Financial assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurement.

The  Company  estimates  the  fair  values  of  proved  oil  and  natural  gas  properties  assumed  in  business  combinations  using  discounted  cash  flow
techniques and based on market assumptions as to the future commodity prices, internal estimates of future quantities of oil and natural gas reserves, future
estimated rates of production, expected recovery rates and risk-adjustment discounts. The estimated fair values of unevaluated oil and natural gas properties
were  based  on  the  location,  engineering  and  geological  studies,  historical  well  performance,  and  applicable  mineral  lease  terms.  Given  the  unobservable
nature  of  the  inputs,  the  estimated  fair  values  of  oil  and  natural  gas  properties  assumed  is  deemed  to  use  Level  3  inputs.  The  asset  retirement  obligations
assumed as part of business combinations are estimated using the same assumptions and methodology as described below.

The  Company  estimates  asset  retirement  obligations  pursuant  to  the  provisions  of  the  Financial  Accounting  Standards  Board  issued  Accounting
Standards Codification Topic 410, “Asset Retirement and Environmental Obligations”. The initial measurement of asset retirement obligations at fair value is
calculated  using  discounted  cash  flow  techniques  and  based  on  internal  estimates  of  future  retirement  costs  associated  with  the  future  plugging  and
abandonment of wells and related facilities. Given the unobservable nature of the inputs, including plugging costs and useful lives, the initial measurement of
the asset retirement obligation liability is deemed to use Level 3 inputs. See Note 8—Asset Retirement Obligations for further discussion of the Company’s
asset retirement obligations.

Assets and Liabilities Measured at Fair Value on a Recurring Basis

Certain assets and liabilities are reported at fair value on a recurring basis, including the Company’s derivative instruments and Viper’s cost method
investment.  The  fair  value  of  Viper’s  investment  is  determined  using  quoted  market  prices.  These  valuations  are  Level  1  inputs.  The  fair  values  of  the
Company’s fixed price swaps, fixed price basis swaps and costless collars are measured internally using established commodity futures price strips for the
underlying commodity provided by a reputable third party, the contracted notional volumes, and time to maturity. These valuations are Level 2 inputs.

The following table provides fair value measurement information for financial assets and liabilities measured at fair value on a recurring basis as of

The fair value of the revolving credit facility, the Viper credit agreement and the Rattler credit agreement approximates their carrying value based on
borrowing rates available to the Company for bank loans with similar terms and maturities and is classified as Level 2 in the fair value hierarchy. The fair
value of the Senior Notes and the Energen Notes was determined using the December 31, 2019 quoted market price, a Level 1 classification in the fair value
hierarchy.

17.    LEASES

The Company leases certain drilling rigs, facilities, compression and other equipment.

As discussed in Note 2—Summary of Significant Accounting Policies, the Company adopted ASU 2016-02, ASU 2018-11 and ASU 2019-01 on
January 1, 2019 using the optional transition method of adoption. The Company elected a package of practical expedients that together allows an entity to not
reassess  (i)  whether  a  contract  is  or  contains  a  lease,  (ii)  lease  classification  and  (iii)  initial  direct  costs.  In  addition,  the  Company  elected  the  following
practical expedients: (i) to not reassess

Notes to Consolidated Financial Statements-(Continued)

certain land easements; (ii) to not apply the recognition requirements under the standard to short-term leases; (iii) to not reassess lease terms on leases entered
into prior to the effective date of adoption; and (iv) lessor accounting policy election to exclude lessor costs paid directly by the lessee.

For  leases  where  the  Company  is  the  lessee,  the  Company  recorded  a  total  of  $13  million  in  right-of-use  assets  and  corresponding  new  lease
liabilities  in  other  on  its  Condensed  Consolidated  Balance  Sheet  representing  the  present  value  of  its  future  operating  lease  payments.  Adoption  of  the
standards did not require an adjustment to the opening balance of retained earnings. The discount rate used to determine present value was based on the rate
of interest that the Company estimated it would have to pay to borrow (on a collateralized-basis over a similar term) an amount equal to the lease payments in
a similar economic environment as of January 1, 2019. The Company is required to reassess the discount rate for any new and modified lease contracts as of
the lease effective date.

The right-of-use assets and lease liabilities recognized upon adoption of ASU 2016-02 were based on the lease classifications, lease commitment
amounts and terms recognized under the prior lease accounting guidance. Leases with an initial term of twelve months or less are considered short-term leases
and are not recorded on the balance sheet.

The following table summarizes operating lease costs for the year ended December 31, 2019:

For the year ended December 31, 2019, cash paid for operating lease liabilities, and reported in cash flows provided by operating activities on the
Company's  Statement  of  Condensed  Consolidated  Cash  Flows,  was  $26  million.  During  the  year  ended  December  31,  2019,  the  Company  recorded  an
additional $17 million of right-of-use assets in exchange for new lease liabilities.

18.    COMMITMENTS AND CONTINGENCIES

The  Company  is  a  party  to  various  legal  proceedings,  disputes  and  claims  arising  in  the  course  of  its  business,  including  those  that  arise  from
interpretation of federal and state laws and regulations affecting the natural gas and crude oil industry, personal injury claims, title disputes, royalty disputes,
contract claims, contamination claims relating to oil and gas exploration and development and environmental claims, including claims involving assets owned
by acquired companies and claims involving assets previously sold to third parties and no longer part of the Company’s current operations. While the ultimate
outcome of the pending proceedings, disputes or claims, and any resulting impact on the Company, cannot be predicted with certainty, the Company believes
that none of these matters, if ultimately decided adversely, will have a material adverse effect on the Company’s financial condition, cash flows or results of
operations.  The  Company’s  assessment  is  based  on  information  known  about  the  pending  matters  and  its  experience  in  contesting,  litigating  and  settling
similar  matters.  Actual  outcomes  could  differ  materially  from  the  Company’s  assessment.  The  Company  records  reserves  for  contingencies  related  to
outstanding legal proceedings, disputes or claims when information available indicates that a loss is probable and the amount of the loss can be reasonably
estimated. The Company reassesses the probability and estimability of contingent losses as new information becomes available.

Agreement with Trafigura Trading LLC

The Company has entered into a firm commitment oil purchase agreement with Trafigura Trading LLC (“Trafigura”) in which the Company agreed
to sell and deliver a firm quantity of 25,000 barrels of crude oil per day to Trafigura during the term of the agreement. Under this agreement, which has a
seven-year term beginning on August 1, 2018, the price per barrel of oil paid to us by Trafigura is based on the average of the published settlement quotations
for  NYMEX  CMA,  as  adjusted  for  different  delivery  methods  and  periods.  If  during  the  term  of  the  agreement  the  Company  fails  to  deliver  the  required
quantities of oil for any month other than for specified force majeure events, the Company has agreed to pay Trafigura a deficiency payment equal to any
unfavorable difference between the contract price and the spot price, multiplied by the deficiency volume.

Agreement with Plains Marketing LP

In July 2019, the Company’s wholly-owned subsidiary, Energen Resources Corporation (“Energen Resources”) entered into a long-term crude oil
sales agreement with Plains Marketing LP (“Plains”) pursuant to which, among other things, the Company’s existing agreements with Plains were terminated.
The Company’s new agreement with Plains requires that it makes available 50,000 barrels of crude oil per day until the date occurring ten years following the
date  service  commences  for  ExxonMobil  Oil  Corporation  (“Exxon”)  pursuant  to  the  transportation  service  agreement  between  Exxon  and  the  Wink  to
Webster pipeline carrier (plus extensions for force majeure). If during the term of the agreement the Company fails to deliver the required quantities of oil for
any month other than for specified force majeure events or acts or omissions of Plains, the Company has agreed to pay Plains a specified per barrel amount,
subject to escalation, multiplied by the deficiency volume. If during the term of the agreement the Company fails to deliver the quantities of oil for any month
that it has committed for such month other than for specified force majeure events or acts or omissions of Plains, the Company has agreed to pay Plains a
deficiency  payment  .  The  Company  has  also  dedicated  certain  crude  oil  production  attributable  to  certain  of  its  interests  to  Plains  in  connection  with  this
agreement. Pricing for the Company’s production under the Plains agreement (i) prior to the date service commences for Exxon pursuant to the transportation
service agreement between Exxon and the Wink to Webster pipeline carrier, is at a Midland WTI or WTL, as applicable, base price less certain costs and (ii)
following the date service commences for Exxon pursuant to the transportation service agreement between Exxon and the Wink to Webster pipeline carrier,
for volumes up to 100,000 barrels of crude oil per day, is at a MEH WTI or WTL base price, as applicable, less certain costs.

Agreement with Shell Trading (USA) Company

In  December  2018,  the  Company  entered  into  an  oil  purchase  agreement  with  Shell  Trading  (USA)  Company  (“Shell”)  which  was  amended  and
restated in December 2019, in which Shell agreed to transport crude oil it purchases from us through the EPIC pipeline, with which the Company has an
agreement  for  the  transportation  of  certain  crude  oil.  The  Company’s  agreement  with  Shell  provides  for  different  purchase  obligations  during  the  pre-
commencement and service commencement periods for the EPIC pipeline, and provides for a three-year term beginning on the service commencement date
for the EPIC pipeline. Shell has the option to extend its purchase obligations for up to three one-year terms, but not beyond March 31, 2026 except in the
event  of  force  majeure.  The  Company’s  delivery  obligation  (i)  prior  to  the  full  service  commencement  of  the  EPIC  pipeline  will  be,  subject  to  certain
conditions, including the Company’s right to repurchase certain volumes, either 30,000 or 40,000 barrels of crude oil per day and (ii) during the full service
term will not exceed 50,000 barrels of crude oil per day. In addition, the Company’s wholly-owned subsidiary Energen Resources has signed an agreement
with  Shell  in  which  all  or  a  portion  of  the  50,000  barrels  of  crude  oil  per  day  referenced  in  the  previous  sentence  could  also  be  satisfied  by  Energen
Resources. During different pre-commencement periods, Shell has agreed to pay the Company the price per barrel of oil based on the arithmetic average of
the daily settlement price for the “Light Sweet Crude Oil” Prompt Month future contracts reported by the NYMEX over the applicable one-month period,
subject to certain adjustments, plus a Corpus Christi differential determined based on Shell’s average sales price for its WTI barrels in Corpus Christi less
certain other costs, expenses and fees. During the full service term, the price per barrel of oil payable by Shell to the Company is based on calendar dated
Brent pricing plus a negotiated differential generally based on certain Argus WTI Houston CIF Rotterdam and Platts Midland DAP Rotterdam pricing, less
certain adjustments.

Agreement with Vitol Inc.

On October 18, 2018, the Company entered into an agreement with Vitol to, among other things, sell an average of 23,750 barrels of crude oil per
day plus other agreed upon volumes. The Company is continuing to sell crude to Vitol on a month-to-month basis and expects to continue to do so under its
existing arrangement with Vitol until its new agreement with Vitol becomes effective. Under the Company’s new agreement with Vitol, the Company agreed
to sell, and Vitol agreed to purchase, (i) subject to certain conditions, including accelerated commissioning service on the Gray Oak pipeline and completion
of certain infrastructure connections, 50,000 barrels of crude oil per day on average during each month occurring during the first seven years of full service on
the  Gray  Oak  pipeline,  (ii)  subject  to  certain  conditions  and  the  satisfaction  of  other  conditions,  including  full  service  on  the  Gray  Oak  pipeline  and
completion of certain infrastructure connections, an additional 50,000 barrels of crude oil per day on average during each month occurring during the first
seven years following satisfaction of such conditions, (iii) subject to certain conditions, including notice that transportation services on the EPIC pipeline are
ready  to  commence  and  completion  of  certain  infrastructure  connections,  an  additional  50,000  barrels  of  crude  oil  per  day  on  average  during  each  month
occurring  during  the  first  seven  years  following  satisfaction  of  such  conditions  and  (iv)  such  other  volumes  of  crude  oil  as  agreed  by  the  parties.  The
Company is entitled to receive payment for such crude oil under netback pricing, whereby the price for the Company’s crude oil is determined based on a
formula which takes into consideration the final purchase price obtained by Vitol in marketing such crude oil in certain third party transactions less certain
costs. In connection therewith, Vitol has agreed to,

F-52

Table of Contents

Diamondback Energy, Inc. and Subsidiaries
Notes to Consolidated Financial Statements-(Continued)

among other things, use commercially reasonable efforts to (i) maximize the final purchase price to the Company and mitigate any costs factored into the
price determination and (ii) acquire third party crude oil to cover any shortfall below the Company’s volumes commitments. Vitol also agrees to (i) use the
same care and apply the same policies as it would exercise and apply if it were trading the subject crude oil for Vitol’s own account and (ii) transport such
crude oil on certain designated pipelines, including the Gray Oak pipeline pursuant to rights we have obtained through our Gray Oak transportation services
agreement described below under third party shipper rights or term assignments, as applicable, prior to Vitol’s downstream marketing activities.

Transportation Services Agreement with Gray Oak Pipeline, LLC

Pursuant to an addendum, dated as of August 13, 2018, to the transportation services agreement with Gray Oak Pipeline, LLC, dated as of April 23,
2018 (the “Gray Oak TSA 1”), Diamondback E&P LLC agreed to accelerated commissioning service (“ACS”) on the Gray Oak pipeline in the amount of
50,000 barrels of crude oil per day. Under the ACS program, shippers must make a deficiency payment for any barrels not shipped during the ACS term,
which expires the day before the Gray Oak pipeline goes into full service, which is currently anticipated to occur in the second quarter of 2020. The ACS
commenced  on  November  12,  2019  and  is  ongoing.  Due  to  restrictive  API  gravity  provisions  and  the  lack  of  markets,  Diamondback  E&P  LLC  has  been
unable to ship any volumes over the Gray Oak pipeline since the inception of ACS. This has resulted in Diamondback E&P LLC owing deficiency payments
to Gray Oak Pipeline, LLC during 2019 in the aggregate amount of $11 million. The deficiency payment rate varies depending upon the month in which the
deficiency occurs. Certain  deficiencies  can  be  used  as  a  credit  against  volumes  shipped  in  excess  of  a  customer’s  minimum  contract  volume  each  quarter
during the first two years of full service on the Gray Oak pipeline, subject to certain restrictions.

Once full service commences on the Gray Oak pipeline, subject to the terms and conditions of the Gray Oak TSA 1, Diamondback E&P LLC will be
required to ship 50,000 barrels per day of crude oil on the Gray Oak pipeline or pay a deficiency payment for any shortfall in volumes as measured on a
quarterly basis. Such deficiency payments can be used as a credit against future shipments in excess of our minimum contract volume each quarter, subject to
certain restrictions.

Defined contribution plan

The Company sponsors a 401(k) defined contribution plan for the benefit of substantially all employees at their date of hire. The plan allows eligible
employees to contribute up to 100% of their annual compensation, not to exceed annual limits established by the federal government. The Company makes
matching contributions of up to 6% of an employee’s compensation and may make additional discretionary contributions for eligible employees. Employer
contributions  vest  immediately.  For  the  years  ended  December  31,  2019,  2018  and  2017  the  Company  paid  $8  million,  $2  million  and  $2  million,
respectively, in contributions to the plan.

As of December 31, 2019, Diamondback O&G LLC is a guarantor under the indenture relating to the Series of Senior Notes. In connection with the
satisfaction  and  discharge  of  the  indenture  governing  the  2024  Senior  Notes,  Diamondback  E&P  LLC  and  Energen  Corporation  and  its  subsidiaries  were
released as guarantors under the 2024 Senior Notes, the 2025 Senior Notes and Diamondback O&G LLC’s revolving credit facility. Rattler LLC was released
as a guarantor under Diamondback O&G LLC’s credit agreement on May 28, 2019. Viper, Viper’s General Partner, Viper LLC, Rattler, Rattler’s General
Partner and Rattler’s subsidiaries remain Non-Guarantor Subsidiaries. The following presents condensed consolidated financial information for the Company
(which for purposes of this Note 21 is referred to as the “Parent”), the Guarantor Subsidiaries and the Non–Guarantor Subsidiaries on a consolidated basis.
Elimination entries presented are necessary to combine the entities. The information is presented in accordance with the requirements of Rule 3-10 under the
SEC’s Regulation S-X. The financial information may not necessarily be indicative of results of operations, cash flows or financial position had the Guarantor
Subsidiaries  operated  as  independent  entities.  The  Company  has  not  presented  separate  financial  and  narrative  information  for  each  of  the  Guarantor
Subsidiaries because it believes such financial and narrative information would not provide any additional information that would be material in evaluating
the sufficiency of the Guarantor Subsidiaries.

None  of  Rattler,  Rattler’s  General  Partner  or  Rattler’s  subsidiaries  were  guarantors  under  the  2024  Senior  Notes,  the  2025  Senior  Notes  or
Diamondback O&G LLC’s revolving credit facility for the previous periods presented; therefore, the schedules that follow have been adjusted to reflect this
correction of an immaterial change. Rattler LLC was a guarantor under Diamondback O&G LLC’s credit agreement until May 28, 2019.

Proved oil and natural gas reserve estimates as of December 31, 2019, 2018 and 2017 were prepared by Ryder Scott Company, L.P., independent
petroleum engineers. Proved reserves were estimated in accordance with guidelines established by the SEC, which require that reserve estimates be prepared
under existing economic and operating conditions based upon the 12-month unweighted average of the first-day-of-the-month prices.

There are numerous uncertainties inherent in estimating quantities of proved oil and natural gas reserves. Oil and natural gas reserve engineering is a
subjective process of estimating underground accumulations of oil and natural gas that cannot be precisely measured and the accuracy of any reserve estimate
is  a  function  of  the  quality  of  available  data  and  of  engineering  and  geological  interpretation  and  judgment.  Results  of  drilling,  testing  and  production
subsequent to the date of the estimate may justify revision of such estimate. Accordingly, reserve estimates are often different from the quantities of oil and
natural gas that are ultimately recovered.

Revisions  represent  changes  in  previous  reserves  estimates,  either  upward  or  downward,  resulting  from  new  information  normally  obtained  from
development drilling and production history or resulting from a change in economic factors, such as commodity prices, operating costs or development costs.

During the year ended December 31, 2019, the Company’s extensions and discoveries totaling 376,287 MBOE resulted primarily from the drilling of
283 new wells and from 291 new proved undeveloped locations added in which the Company owns a working interest. Viper royalty interests accounted for
5% of the extension volumes. The Company’s downward revisions of 117,898 MBOE were the result of proved undeveloped downgrades associated with
inventory refinement following the Energen acquisition along with updated development plans and lower realized prices.  Purchases of 21,092 MBOE were
the result of 10,939 MBOE of working interest purchases and 10,153 MBOE of Viper royalty purchases, excluding mineral interests dropped down to Viper.

During the year ended December 31, 2018, the Company’s extensions and discoveries of 202,089 MBOE resulted primarily from the drilling of 135

new wells and from 138 new proved undeveloped locations added in which the Company

owns a working interest. Viper royalty interests accounted for 10% of the extension volumes. The Company’s revisions of previous estimates were primarily
the result of positive technical and performance revisions of 14,218 MBOE, upward revisions of 6,032 MBOE due to higher pricing and downward revisions
of 4,815 MBOE from PUD reclassifications due to timing. Purchases of 486,992 MBOE were the result of 477,686 of working interest purchases, primarily
attributable to Energen, and 9,306 MBOE of Viper royalty purchases.

During the year ended December 31, 2017, the Company’s extensions and discoveries of 138,977 MBOE resulted primarily from the drilling of 102
new  wells  and  from  87  new  proved  undeveloped  locations  added.  Viper  royalty  interests  accounted  for  8%  of  the  extension  volumes.  The  Company’s
revisions of previous estimates were primarily the result of 2,550  MBOE  from  reclassifying  PUD  locations  due  to  anticipated  timing,  with  the  remaining
8,308  MBOE  being  technical  revisions.  Delaware  Basin  working  interest  purchases  accounted  for  87%  of  the  total  purchases  and  Viper  royalty  interest
purchases accounted for 10%, with working interest purchases contributing the remainder.

At December  31,  2019,  the  Company’s  estimated  PUD  reserves  were  approximately  367,859  MBOE,  a  21,931  MBOE  increase  over  the  reserve

estimate at December 31, 2018 of 345,928 MBOE. The following table includes the changes in PUD reserves for 2019:

(77,519)

(5,672)

367,859

The increase in proved undeveloped reserves was primarily attributable to extensions of 213,909 MBOE from 291 gross (262 net) wells in which the
Company has a working interest and 7,591 MBOE from 97 gross wells in which Viper owns royalty interests. Of the 291 gross working interest wells, 64
were  in  the  Delaware  Basin.  Transfers  of  120,920  MBOE  were  the  result  of  drilling  or  participating  in  135  gross  (119  net)  horizontal  wells  in  which  the
Company has a working interest and 79 gross wells in which the Company has a royalty interest or mineral interest through Viper. The Company owns a
working interest in 75 of the 79 gross Viper wells. Downward revisions of 77,519 MBOE resulted from 67,114 MBOE of PUD downgrades due to refinement
of  the  PUD  inventory  following  the  acquisition  of  Energen.  These  downgrades  were  offset  with  Extensions.  The  remaining  10,405  MOE  of  downward
revisions were mostly from lower benchmark commodity prices.

As of December 31, 2019, all of the Company’s proved undeveloped reserves are planned to be developed within five years from the date they were
initially recorded. During 2019, approximately $956 million  in  capital  expenditures  went  toward  the  development  of  proved  undeveloped  reserves,  which
includes drilling, completion and other facility costs associated with developing proved undeveloped wells.

Standardized Measure of Discounted Future Net Cash Flows

The  standardized  measure  of  discounted  future  net  cash  flows  is  based  on  the  unweighted  average,  first-day-of-the-month  price.  The  projections
should not be viewed as realistic estimates of future cash flows, nor should the “standardized measure” be interpreted as representing current value to the
Company.  Material  revisions  to  estimates  of  proved  reserves  may  occur  in  the  future;  development  and  production  of  the  reserves  may  not  occur  in  the
periods assumed; actual prices realized are expected to vary significantly from those used; and actual costs may vary.

DESCRIPTION OF THE REGISTRANT’S SECURITIES REGISTERED PURSUANT TO SECTION 12 OF THE SECURITIES EXCHANGE
ACT OF 1934

The following is a summary of common stock of Diamondback Energy, Inc. (the “Company,” “we,” “us,” and “our”), which is the only class of
securities registered under Section 12 of the Securities Exchange Act of 1934, as amended. The following summary is not complete. You should refer to
the applicable provisions of our Amended and Restated Certificate of Incorporation and the Certificate of Amendment No. 1 of the Amended and
Restated Certificate of Incorporation and any subsequent amendments thereto (collectively, “our certificate of incorporation”), our Amended and
Restated Bylaws, the First Amendment to our Amended and Restated Bylaws and any subsequent amendments thereto (collectively, “our bylaws”) and
the Delaware General Corporation Law (the “DGCL”) for a complete statement of the terms and rights of our common stock. Copies of our Amended
and Restated Certificate of Incorporation, Amendment No. 1 thereto, our Amended and Restated Bylaws and the First Amendment thereto have been
filed with the Securities and Exchange Commission as exhibits 3.1, 3.2, 3.3 and 3.4, respectively, to our Annual Report on Form 10-K.

Exhibit 4.1

Authorized Capital Stock

Our authorized capital stock consists of 200,000,000 shares of common stock, par value $0.01 per share, and 10,000,000 shares of preferred stock,

par value $0.01 per share.

Common Stock

Holders of shares of common stock are entitled to one vote per share on all matters submitted to a vote of stockholders. Shares of common stock do
not have cumulative voting rights, which means that the holders of more than 50% of the shares voting for the election of the board of directors can elect all
the directors to be elected at that time, and, in such event, the holders of the remaining shares will be unable to elect any directors to be elected at that time.
Our certificate of incorporation denies stockholders any preemptive rights to acquire or subscribe for any stock, obligation, warrant or other securities of ours.
Holders of shares of our common stock have no redemption or conversion rights nor are they entitled to the benefits of any sinking fund provisions.

In the event of our liquidation, dissolution or winding up, holders of shares of common stock shall be entitled to receive, pro rata, all the remaining

assets of our company available for distribution to our stockholders after payment of our debts and after there shall have been paid to or set aside for the
holders of capital stock ranking senior to common stock in respect of rights upon liquidation, dissolution or winding up the full preferential amounts to which
they are respectively entitled.

Holders of record of shares of common stock are entitled to receive dividends when and if declared by the board of directors out of any assets legally

available for such dividends, subject to both the rights of all outstanding shares of capital stock ranking senior to the common stock in respect of dividends
and to any dividend restrictions contained in debt agreements. All outstanding shares of common stock and any shares sold and issued in this offering will be
fully paid and nonassessable by us. As of February 14, 2020, there were 158,284,486 shares of our common stock outstanding.

Preferred Stock

Our board of directors is authorized to issue up to 10,000,000 shares of preferred stock in one or more series. The board of directors may fix for each

series:

•

•

•

•

•

•

•

•

the distinctive serial designation and number of shares of the series;

the voting powers and the right, if any, to elect a director or directors;

the terms of office of any directors the holders of preferred shares are entitled to elect;

the dividend rights, if any;

the terms of redemption, and the amount of and provisions regarding any sinking fund for the purchase or redemption thereof;

the liquidation preferences and the amounts payable on dissolution or liquidation;

the terms and conditions under which shares of the series may or shall be converted into any other series or class of stock or debt of the
corporation; and

any other terms or provisions which the board of directors is legally authorized to fix or alter.

We do not need stockholder approval to issue or fix the terms of the preferred stock. The actual effect of the authorization of the preferred stock upon

your rights as holders of common stock is unknown until our board of directors determines the specific rights of owners of any series of preferred stock.
Depending upon the rights granted to any series of preferred stock, your voting power, liquidation preference or other rights could be adversely affected.
Preferred stock may be issued in acquisitions or for other corporate purposes. Issuance in connection with a stockholder rights plan or other takeover defense
could have the effect of making it more difficult for a third party to acquire, or of discouraging a third party from acquiring, control of our company. We
currently have no outstanding preferred stock and have no present plans to issue any shares of preferred stock.

Related Party Transactions and Corporate Opportunities

Subject to the limitations of applicable law, our certificate of incorporation, among other things:

•

•

•

permits us to enter into transactions with entities in which one or more of our officers or directors are financially or otherwise interested so long as it
has been approved by our board of directors;

permits certain of our stockholders, officers and directors, including our non-employee directors, to conduct business that competes with us and to
make investments in any kind of property in which we may make investments; and

provides that if certain of our officers or directors, including our non-employee directors, becomes aware of a potential business opportunity,

transaction or other matter (other than one expressly offered to that director or officer solely in his or her capacity as our director or officer), that
director or officer will have no duty to communicate or offer that opportunity to us, and will be permitted to communicate or offer that opportunity to
any other entity or individual and that director or officer will not be deemed to have (i) acted in a manner inconsistent with his or her fiduciary duty
to us or our stockholders regarding the opportunity or (ii) acted in bad faith or in a manner inconsistent with our best interests.

Anti-takeover Effects of Provisions of Our Certificate of Incorporation and Our Bylaws

Some provisions of our certificate of incorporation and our bylaws contain provisions that could make it more difficult to acquire us by means of a

merger, tender offer, proxy contest or otherwise, or to remove our incumbent officers and directors. These provisions, summarized below, are expected to
discourage coercive takeover practices and inadequate takeover bids. These provisions are also designed to encourage persons seeking to acquire control of us
to first negotiate with our board of directors. We believe that the benefits of increased protection of our potential ability to negotiate with the proponent of an
unfriendly or unsolicited proposal to acquire or restructure us outweigh the disadvantages of discouraging such proposals because negotiation of such
proposals could result in an improvement of their terms.

Undesignated preferred stock. The ability to authorize and issue undesignated preferred stock may enable our board of directors to render more

difficult or discourage an attempt to change control of us by means of a merger, tender offer, proxy contest or otherwise. For example, if in the due exercise of
its fiduciary obligations, the board of directors were to determine that a takeover proposal is not in our best interest, the board of directors could cause shares
of preferred stock to be issued without stockholder approval in one or more private offerings or other transactions that might dilute the voting or other rights
of the proposed acquirer or insurgent stockholder or stockholder group.

Stockholder meetings. Our certificate of incorporation and bylaws provide that a special meeting of stockholders may be called only by the

Chairman of the Board, the Chief Executive Officer or by a resolution adopted by a majority of our board of directors, assuming there are no vacancies.

Requirements for advance notification of stockholder nominations and proposals. Our bylaws establish advance notice procedures with respect to
stockholder proposals and the nomination of candidates for election as directors, other than nominations made by or at the direction of the board of directors.

Stockholder action by written consent. Our certificate of incorporation provides that, except as may otherwise be provided with respect to the rights

of the holders of preferred stock, no action that is required or permitted to be taken by our stockholders at any annual or special meeting may be effected by
written consent of stockholders in lieu of a meeting of stockholders, unless the action to be effected by written consent of stockholders and the taking of such
action by such written consent have expressly been approved in advance by our board. This provision, which may not be amended except by the affirmative
vote of at least 66 2/3% of the voting power of all then outstanding shares of capital stock entitled to vote generally in the election of directors, voting
together as a single class, makes it difficult for stockholders to initiate or effect an action by written consent that is opposed by our board.

Amendment of the bylaws. Under Delaware law, the power to adopt, amend or repeal bylaws is conferred upon the stockholders. A corporation may,

however, in its certificate of incorporation also confer upon the board of directors the power to adopt, amend or repeal its bylaws. Our certificate of
incorporation and bylaws grant our board the power to adopt, amend and repeal our bylaws at any regular or special meeting of the board on the affirmative
vote of a majority of the directors, assuming there are no vacancies. Our stockholders may adopt, amend or repeal our bylaws but only at any regular or
special meeting of stockholders by an affirmative vote of holders of at least 66 2/3% of the voting power of all then outstanding shares of capital stock
entitled to vote generally in the election of directors, voting together as a single class.

Removal of Director. Our certificate of incorporation provide that members of our board of directors may only be removed by the affirmative vote of

holders of at least 66 2/3% of the voting power of all then outstanding shares of capital stock entitled to vote generally in the election of directors, voting
together as a single class.

Amendment of the Certificate of Incorporation. Our certificate of incorporation provides that, in addition to any other vote that may be required by

law or any preferred stock designation, the affirmative vote of the holders of at least 66 2/3% of the voting power of all then outstanding shares of capital
stock entitled to vote generally in the election of directors, voting together as a single class, is required to amend, alter or repeal, or adopt any provision as
part of our certificate of incorporation inconsistent with the provisions of our certificate of incorporation dealing with distributions on our common stock,
related party transactions, our board of directors, our bylaws, meetings of our stockholders or amendment of our certificate of incorporation.

Additionally, an increase in the number of authorized shares of our common stock, could be used to make it more difficult to, or discourage an

attempt to, obtain control of our company by means of a takeover bid that our board of directors determines is not in our best interests or the best interests of
our stockholders. However, our board of directors does not intend or view the proposed increase in authorized common stock as an anti-takeover measure and
did not propose the increase in response to any attempt or plan to obtain control of the company.

The provisions of our certificate of incorporation and bylaws could have the effect of discouraging others from attempting hostile takeovers and, as a

consequence, they may also inhibit temporary fluctuations in the market price of our common stock that often result from actual or rumored hostile takeover
attempts. These provisions may also have the effect of preventing changes in our management. It is possible that these provisions could make it more difficult
to accomplish transactions which stockholders may otherwise deem to be in their best interests.

Choice of Forum

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 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 or other employees to us or our stockholders; (iii) any action asserting a claim against us arising
pursuant to any provision of the DGCL or our certificate of incorporation or bylaws; or (iv) any action asserting a claim against us pertaining to internal
affairs of our corporation. Our certificate of incorporation also provides that any person or entity purchasing or otherwise acquiring any interest in shares of
our capital stock will be deemed to have notice of and to have consented to this choice of forum provision. It is possible that a court of law could rule that the
choice of forum provision contained in our certificate of incorporation is inapplicable or unenforceable if it is challenged in a proceeding or otherwise.

Listing

Our common stock is listed on The Nasdaq Global Select Market under the symbol “FANG.”

DIAMONDBACK ENERGY, INC. 
2019 AMENDED AND RESTATED EQUITY INCENTIVE PLAN 
RESTRICTED STOCK UNIT AWARD AGREEMENT

This  Restricted  Stock  Unit  Award  Agreement  (this  “Agreement”),  is  made  and  entered  into  on  the  execution  date  of  the
Restricted Stock Unit Award Certificate to which it is attached (the “Certificate”), by and between Diamondback Energy, Inc., a
Delaware corporation (the “Company”), and the Participant named in the Certificate.

Pursuant  to  the  Diamondback  Energy,  Inc.  2019  Amended  and  Restated  Equity  Incentive  Plan  (the  “Plan”),  the
Administrator  has  authorized  the  grant  to  Participant  of  the  number  of  Restricted  Stock  Units  set  forth  in  the  Certificate  (the
“Award”), upon the terms and subject to the conditions set forth in this Agreement and in the Plan. Capitalized terms not otherwise
defined herein have the meanings ascribed to them in the Plan.

NOW, THEREFORE, in consideration of the premises and the benefits to be derived from the mutual observance of the
covenants  and  promises  contained  herein  and  other  good  and  valuable  consideration,  the  sufficiency  of  which  is  hereby

 
 
 
 
 
 
 
 
acknowledged, the parties hereto agree as follows:

1.        Basis  for  Award.  This  Award  is  made  pursuant  to  Section  7.1  of  the  Plan  for  valid  consideration  provided  to  the
Company  by  Participant.  By  Participant’s  execution  of  the  Certificate,  Participant  agrees  to  accept  the  Award  rights  granted
pursuant to the Certificate and this Agreement, and to receive the Restricted Stock Units designated in the Certificate subject to the
terms of the Plan, the Certificate, and this Agreement.

2.    Restricted Stock Units Awarded.

2.1    The Company hereby grants to Participant the number of Restricted Stock Units set forth in the Certificate.
Each Restricted Stock Unit represents a right to receive one share of Common Stock from the Company payable in accordance with
Section 5 below and any Dividend Equivalents (as defined below) credited to the Participant’s Restricted Stock Unit Account (as
defined below) with respect to that share.

2.2    The Company will, in accordance with the Plan, establish and maintain an account (the “Restricted Stock Unit
Account”)  for  Participant,  and  will  credit  such  account  for  the  number  of  Restricted  Stock  Units  granted  to  Participant  and  any
Dividend Equivalents as provided in Section 4 below. On any given date, the value of each Restricted Stock Unit will equal the Fair
Market Value on such date of one share of Common Stock.

3.    Vesting.

3.1    The Restricted Stock Units will vest pursuant to the Vesting Schedule set forth in the Certificate. Except as
otherwise provided in an employment agreement, severance plan participation agreement or other service agreement between the
Participant and the Company or an Affiliate (a “Service Agreement”) or as provided in Sections 3.2, 3.3 or 3.4 below, if Participant
ceases  Continuous  Service  for  any  reason,  Participant  will  immediately  forfeit  the  unvested  Restricted  Stock  Units  and  any
securities, other property or amounts nominally credited to the Restricted Stock Unit Account, including any Dividend Equivalents
credited to the Restricted Stock Unit Account that have not been settled or paid.

3.2    Except as otherwise provided in a Service Agreement, in the event of Participant’s involuntary termination of
employment  (other  than  for  Cause,  or  on  account  of  death  or  Disability)  or  resignation  for  Good  Reason,  in  either  case,  in
connection with the consummation of or within 24 months after the occurrence of a Change in Control (as defined in the Plan), (an
“Acceleration Event”), with respect to any Restricted Stock Units then outstanding under this Award, the Restricted Stock Units,
including  any  unpaid  Dividend  Equivalents  credited  to  the  Restricted  Stock  Unit  Account,  will  vest  immediately  upon  the
occurrence of an Acceleration Event and will be settled upon the consummation of such Acceleration Event.

3.3        Except  as  otherwise  provided  in  a  Service  Agreement,  in  the  event  of  the  Participant’s  death  or  Disability
during  a  period  of  Continuous  Service,  the  deceased  or  Disabled  Participant’s  Restricted  Stock  Units,  including  any  unpaid
Dividend Equivalents credited to the Restricted Stock Unit Account, will become 100% vested. Participant’s Restricted Stock Units
and unpaid Dividend Equivalents will be settled and paid in full within 10 business days following the date of vesting.

3.4    To the extent that a Service Agreement provides for acceleration of vesting of any or all unvested Restricted
Stock Units on termination of Continuous Service that is more favorable to Participant than the provisions of this Agreement, such
provisions are incorporated by reference in this Agreement.

3.5        For  purposes  of  this  Agreement,  “Good  Reason”  means  Participant’s  resignation  in  the  event  of  any  (a)
material  reduction  in  Participant’s  base  salary,  bonus  opportunity  or  severance  benefits;  (b)  relocation  of  Participant’s  principal
office  more  than  25  miles  from  the  current  location,  or  (c)  material  diminution  in  the  Participant’s  position,  duties,  reporting
relationship or authority, which in any case is not cured within thirty (30) business days after written notice thereof by you to the
Board (which notice must be provided by you to the Company within 90 days following the initial occurrence of such event) and an
opportunity to cure within the notice period (the “Cure Period”). Resignation by the Participant following the Employer’s cure or
before  the  expiration  of  the  Cure  Period  will  constitute  a  voluntary  resignation  and  not  a  termination  or  resignation  for  Good
Reason  and  will  not  entitle  the  Participant  to  any  benefits  under  this  Plan.  Any  termination  on  account  of  a  Good  Reason
Resignation must occur within 120 days following the initial occurrence of such event.

4.    Dividend Equivalents. If the Company pays any cash dividend on its outstanding Common Stock for which the record
date occurs after the Date of Grant, the Administrator will credit the Restricted Stock Unit Account as of the dividend payment date
in an amount equal to the amount of the dividend paid by the Company on a single Share multiplied by the number of Restricted
Stock Units under this Agreement that are unvested as of that record date and that are vested but have not been settled under the
payment terms of Section 5 (“Dividend Equivalents”). Except as otherwise provided in Section 3, Dividend Equivalents will vest
and be paid to the Participant on the dividend payment date if Participant is in Continuous Service on the dividend payment date
declared by the Company.

5.        Payment/Settlement.  Subject  to  Participant’s  satisfaction  of  the  applicable  withholding  requirements  pursuant  to
Section 7 hereof, the Company will settle the Award on the Payment/Settlement Date or Dates set forth in the Certificate by issuing
to Participant one share of Common Stock for each Restricted Stock Unit payable on that Payment/Settlement Date (and upon such
settlement, the Restricted Stock Units will cease to be credited to the Restricted Stock Unit Account). If the Certificate does not

specify a Payment/Settlement Date, the applicable Payment/Settlement Date will be within 10 business days after each vesting date
set forth in the Vesting Schedule. If an Acceleration Event occurs, the Payment/Settlement Date will be the date the Acceleration
Event occurs. The Administrator will enter Participant’s name as a stockholder of record with respect to such shares of Common
Stock on the books of the Company with respect to the shares of Common Stock issued on that Payment/Settlement Date free of all
restrictions hereunder, except for applicable federal and state securities law restrictions. Participant acknowledges and agrees that
shares of Common Stock may be issued in electronic form as a book entry with the Company’s transfer agent and that no physical
certificates need be issued. Any securities, other property or amounts nominally credited to the Restricted Stock Unit Account other
than Restricted Stock Units will be paid in kind or, in the Administrator’s discretion, in cash. Dividend Equivalents will vest and be
paid to the Participant on the dividend payment date if Participant is in Continuous Service on the dividend payment date declared
by the Company. To the extent that a Service Agreement provides for acceleration of vesting of any or all unvested Restricted Stock
Units on termination of Continuous Service, such provisions are incorporated by reference in this Agreement.

6.        Compliance  with  Laws  and  Regulations.  The  issuance  and  transfer  of  shares  of  Common  Stock  on  any
Payment/Settlement Date will be subject to the Company’s and Participant’s full compliance, to the satisfaction of the Company
and its counsel, with all applicable requirements of federal, state, and foreign securities laws and with all applicable requirements
of  any  securities  exchange  on  which  the  Common  Stock  may  be  listed  at  the  time  of  such  issuance  or  transfer.  Participant
understands that the Company is under no obligation to register or qualify the shares of Common Stock with the U.S. Securities and
Exchange Commission (“SEC”), any state securities commission, foreign securities regulatory authority, or any securities exchange
to effect such compliance.

7.    Tax Withholding.

7.1    As a condition to payment under Section 5 hereof, Participant agrees that on or before the date as of which any
portion of the Restricted Stock Units vest, Participant will pay to the Company any federal, state, or local taxes required by law to
be withheld with respect to the Restricted Stock Units for which the restrictions lapse and any related securities, other property or
amounts then nominally credited to the Restricted Stock Unit Account.

7.2    Participant will pay the amounts due under this Section 7 to the Company. Such amounts will be paid by Stock
Withholding or may be paid, at Participant’s election, in cash, or (to the extent any applicable insider trading policy, window or
restriction  does  not  prohibit  Participant  from  engaging  in  a  sale  transaction)  by  tendering  shares  of  Common  Stock  held  by
Participant to a broker selected by the Company for immediate sale and remittance of proceeds equal to the required withholding
amount  to  the  Company,  including  shares  that  otherwise  would  be  issued  and  transferred  to  Participant  as  payment  on  the
applicable Payment/Settlement Date, with a Fair Market Value on that Payment/Settlement Date that does not exceed the maximum
statutory  tax  rates  in  the  applicable  jurisdictions  (subject  to  the  Participant’s  written  request  to  withhold  more  than  the  required
regular tax withholding in the applicable jurisdictions), or a combination of cash and shares of Common Stock. If Participant fails
to  make  such  payments,  the  Company  or  its  Affiliates  will,  to  the  extent  permitted  by  law,  have  the  right  to  deduct  from  any
payment of any kind otherwise due to Participant any federal, state, or local taxes required by law to be withheld with respect to
such payment. Dividend Equivalents credited to the Restricted Stock Unit Account will be subject to withholding at the time of
payment.

8.    Not Transferrable. Until  the  applicable  Payment/Settlement  Date,  the  Restricted  Stock  Units,  any  related  Dividend
Equivalents credited to the Restricted Stock Unit Account and any related securities, other property or amounts nominally credited
to the Restricted Stock Unit Account may not be sold, transferred, or otherwise disposed of, and may not be pledged or otherwise
hypothecated other than by will or by the applicable laws of descent and distribution, provided that the Restricted Stock Units and
any related Dividend Equivalents credited to the Restricted Stock Unit Account will remain subject to the terms of the Plan, the
Certificate and this Agreement.

9.    No Right to Continued Service. Nothing in this Agreement or in the Plan imposes or may be deemed to impose, by
implication or otherwise, any limitation on any right of the Company or any Affiliate to terminate Participant’s Continuous Service
at any time.

10.    Participant’s Representations and Warranties. Participant represents and warrants to the Company that Participant
has received a copy of the Plan, has read and understands the terms of the Plan, the Certificate, and this Agreement, and agrees to
be  bound  by  their  terms  and  conditions.  Participant  acknowledges  that  there  may  be  tax  consequences  upon  the  payment  of  the
Restricted  Stock  Units,  disposition  of  any  shares  of  Common  Stock  received  on  a  Payment/Settlement  Date  or  payment  of  any
Dividend Equivalents credited to the Restricted Stock Unit Account, and that Participant should consult a tax advisor before such
time.  Participant  agrees  to  sign  such  additional  documentation  as  the  Company  may  reasonably  require  from  time  to  time.
Participant  acknowledges  that  he  or  she  is  aware  that  copies  of  the  Plan  document  and  the  Company’s  financial  statements  and
information heretofore filed by the Company with the Securities and Exchange Commission (the “SEC”) are available upon request
to the Company, at the SEC’s Public Reference Room at 100 F Street, N.E., Room 1580, Washington, D.C. 20549, or by visiting
the SEC Internet site at http://www.sec.gov that contains reports, proxy and information statements and other information regarding
registrants that file electronically with the SEC.

11.        No  Interest  in  Company  Assets.  All  amounts  nominally  credited  to  Participant’s  Restricted  Stock  Unit  Account
under this Agreement will continue for all purposes to be part of the general assets of the Company. Participant’s  interest  in  the

Restricted Stock Unit Account will make Participant only a general, unsecured creditor of the Company.

12.    No Stockholder Rights before Delivery. Participant will not have any right, title, or interest in, or be entitled to vote
or to receive distributions in respect of, or otherwise be considered the owner of, any of the shares of Common Stock covered by
the Restricted Stock Units until the Payment/Settlement Dates specified in the Certificate at which such shares of Common Stock
are issued pursuant to Section 5 hereof.

13.    Modification. The Agreement may not be amended or otherwise modified except in writing signed by both parties.

14.    Interpretation. Any dispute regarding the interpretation of this Agreement must be submitted by Participant or the
Company to the Administrator for review. The resolution of such a dispute by the Administrator will be final and binding on the
Company and Participant.

15.    Entire Agreement. The Plan and the Certificate are incorporated herein by reference. This Agreement, the Certificate,
and the Plan constitute the entire agreement of the parties and supersede all prior undertakings and agreements with respect to the
subject matter hereof. If any inconsistency or conflict exists between the terms and conditions of this Agreement, the Certificate,
and the Plan, the Plan will govern.

16.    Successors and Assigns. The Company may assign any of its rights under this Agreement. This Agreement will bind
and inure to the benefit of the successors and assigns of the Company. Subject to the restrictions on transfer set forth herein, this
Agreement  is  binding  upon  Participant  and  Participant’s  heirs,  executors,  administrators,  legal  representatives,  successors,  and
assigns.

17.        Governing Law. This  Agreement  will  be  governed  by  and  construed  in  accordance  with  the  laws  of  the  State  of
Delaware without giving effect to its conflict of law principles. If any provision of this Agreement is determined by a court of law
to be illegal or unenforceable, then such provision will be enforced to the maximum extent possible and the other provisions will
remain fully effective and enforceable.

ADDENDUM
Definition of “Relative Total Stockholder Return Percentile”

For  purposes  of  this  Performance  Award,  “Relative  Total  Stockholder  Return  Percentile”  means  for  the  Performance
Period, the compound annual growth rate amount determined for the Common Stock of the Company equal to the growth in capital
from purchasing a share in the Company assuming that the dividends are reinvested each time they are paid (the net stock price
change plus the dividends paid during that period = “Total Stockholder Return”) in comparison to the Total Stockholder Return
for each of the companies comprising the Company’s Peer Group designated by the Compensation Committee as defined below.
How the Company’s Total Stockholder Return ranks by percentile relative to the Total Stockholder Return of the other Peer Group
companies determines whether the Restricted Stock Unit Target Award vests and how many shares of Common Stock are paid out.

The Company’s percentile ranking among the Peer Group Total Stockholder Return is calculated by ranking the Company’s
Total Stockholder Return as part of the Total Stockholder Return for the Peer Group as a whole. Total Stockholder Return for each
member of the Peer Group, including the Company, is determined over a particular measurement period by: dividing (1) the sum of
(a)  the  cumulative  value  of  dividends  received  during  the  measurement  period,  assuming  reinvestment,  plus  (b)  the  difference
between  the  average  share  price  for  the  five  trading  days  ending  with  the  last  day  of  the  Performance  Period  compared  to  the
average  share  price  for  the  five  trading  days  ending  immediately  prior  to  the  beginning  of  the  Performance  Period;  by  (2)  the
average share price for the five trading days ending immediately prior to the beginning of the Performance Period. For this purpose,
we assume dividends are reinvested in stock at market prices at approximately the same time actual dividends are paid. Shareholder
return is quoted on an annualized basis. This is expressed as a compound annual growth rate percentage calculated as TSR = (Pe –
Pb + Dividends)/Pb where:

Pb = average share price for the five trading days ending immediately prior to the beginning of the Performance Period;

Pe = average share price for the five trading days ending with the last day of the Performance Period,

Dividends = dividends paid over the Performance Period; and

TSR = Total Shareholder Return.

The Company’s Peer Group consists of the following members:

Apache  Corporation;  Cimarex  Energy  Co.;  Concho  Resources  Inc.;  Continental  Resources,  Inc.;  Devon  Energy
Corporation; Encana Corporation; EOG Resources, Inc.; Hess Corporation; Marathon Oil Corporation; Noble Energy, Inc.; Parsley
Energy, Inc.; Pioneer Natural Resources Company; WPX Energy, Inc.

Definition of “Absolute TSR Modifier”

For purposes of this Performance Award, “Absolute TSR Modifier” means the percentage determined for the Performance
Period  as  specified  in  the  schedule  set  forth  above  based  on  the  Company’s  annualized  Absolute  Total  Shareholder  Return  (as
defined above in the definition of “Relative Total Stockholder Return Percentile”) for the Performance Period.

   
DIAMONDBACK ENERGY, INC. 
2019 AMENDED AND RESTATED EQUITY INCENTIVE PLAN 
RESTRICTED STOCK UNIT AWARD AGREEMENT

This  Restricted  Stock  Unit  Award  Agreement  (this  “Agreement”),  is  made  and  entered  into  on  the  execution  date  of  the
Restricted Stock Unit Award Certificate to which it is attached (the “Certificate”), by and between Diamondback Energy, Inc., a
Delaware corporation (the “Company”), and the Participant named in the Certificate.

Pursuant  to  the  Diamondback  Energy,  Inc.  2019  Amended  and  Restated  Equity  Incentive  Plan  (the  “Plan”),  the
Administrator  has  authorized  the  grant  to  Participant  of  the  number  of  Restricted  Stock  Units  set  forth  in  the  Certificate  (the
“Award”), upon the terms and subject to the conditions set forth in this Agreement and in the Plan. Capitalized terms not otherwise
defined herein have the meanings ascribed to them in the Plan.

NOW, THEREFORE, in consideration of the premises and the benefits to be derived from the mutual observance of the
covenants  and  promises  contained  herein  and  other  good  and  valuable  consideration,  the  sufficiency  of  which  is  hereby
acknowledged, the parties hereto agree as follows:

1.        Basis  for  Award.  This  Award  is  made  pursuant  to  Section  7.1  of  the  Plan  for  valid  consideration  provided  to  the
Company  by  Participant.  By  Participant’s  execution  of  the  Certificate,  Participant  agrees  to  accept  the  Award  rights  granted
pursuant to the Certificate and this Agreement, and to receive the Restricted Stock Units designated in the Certificate subject to the
terms of the Plan, the Certificate, and this Agreement.

2.    Restricted Stock Units Awarded.

2.1       The Company hereby grants to Participant the number of Restricted Stock Units set forth in the Certificate.
Each Restricted Stock Unit represents a right to receive one share of Common Stock from the Company payable in accordance with
Section 5 below and any Dividend Equivalents (as defined below) credited to the Participant’s Restricted Stock Unit Account (as
defined below) with respect to that share.

2.2    The Company will, in accordance with the Plan, establish and maintain an account (the “Restricted Stock Unit
Account”)  for  Participant,  and  will  credit  such  account  for  the  number  of  Restricted  Stock  Units  granted  to  Participant  and  any
Dividend Equivalents as provided in Section 4 below. On any given date, the value of each Restricted Stock Unit will equal the Fair
Market Value on such date of one share of Common Stock.

3.    Vesting.

3.1    The Restricted Stock Units will vest based on the Target Grant Vesting Percentage as adjusted by the Absolute
TSR Modifier, in each case, as determined under the Performance Vesting Goals and Schedules set forth in the Certificate. Except
as otherwise provided in an employment agreement, severance plan participation agreement or other service agreement between the
Participant and the Company or an Affiliate (a “Service Agreement”) or as provided in Sections 3.2, 3.3 or 3.4 below, if Participant
ceases Continuous Service for any reason prior to the end of the Performance Period, Participant will immediately forfeit all the
unvested  Restricted  Stock  Units  and  any  securities,  other  property  or  amounts  nominally  credited  to  the  Restricted  Stock  Unit
Account, including any Dividend Equivalents credited to the Restricted Stock Unit Account that have not been settled or paid.

3.2    Except as otherwise provided in a Service Agreement, in the event of Participant’s involuntary termination of
employment  (other  than  for  Cause,  or  on  account  of  death  or  Disability)  or  resignation  for  Good  Reason,  in  either  case,  in
connection with the consummation of or within 24 months after the occurrence of a Change in Control (as defined in the Plan), (an
“Acceleration  Event”),  with  respect  to  any  Restricted  Stock  Units  then  outstanding  under  this  Award,  the  Relative  Total
Stockholder  Return  Percentile  and  Absolute  TSR  Modifier  used  to  determine  the  number  of  Restricted  Stock  Units  that  will
become vested on the Acceleration Event will be determined based on a Performance Period that ends on the last trading day of the
month preceding the date the Change in Control is consummated (the “Accelerated Performance Period”). The Total Stockholder
Return of the Peer Group will be measured based on the reported closing stock price on the principal exchange on the last day of
the  Accelerated  Performance  Period,  and  the  Total  Stockholder  Return  of  the  Company  will  be  measured  on  the  last  day  of  the
Accelerated  Performance  Period  based  on  the  price  per  share  payable  to  stockholders  of  the  Company  in  connection  with  the
Acceleration  Event.  The  number  of  shares  determined  based  on  the  Relative  Total  Stockholder  Return  Percentile  for  the
Accelerated Performance Period, as adjusted by the Absolute TSR Modifier, including any unpaid Dividend Equivalents credited to
the Restricted Stock Unit Account, will vest immediately and will be settled and paid upon the consummation of such Acceleration
Event.

3.3        In  the  event  of  the  Participant’s  death  or  Disability  during  a  period  of  Continuous  Service,  the  deceased  or
Disabled Participant’s Target Grant Vesting Percentage will be determined at the end of the Performance Period and the deceased or
Disabled  Participant’s  Restricted  Stock  Units,  including  any  unpaid  Dividend  Equivalents  credited  to  the  Restricted  Stock  Unit
Account,  will  be  settled  and  paid  at  the  same  Payment/Settlement  Date  as  if  the  Participant  remained  in  Continuous  Service
through the end of the Performance Period.

3.4    To the extent that a Service Agreement provides for acceleration of vesting of any or all unvested Restricted
Stock Units on termination of Continuous Service that is more favorable to Participant than the provisions of this Agreement, such
provisions are incorporated by reference in this Agreement.

3.5        For  purposes  of  this  Agreement,  “Good  Reason”  means  Participant’s  resignation  in  the  event  of  any  (a)
material  reduction  in  Participant’s  base  salary,  bonus  opportunity  or  severance  benefits;  (b)  relocation  of  Participant’s  principal
office  more  than  25  miles  from  the  current  location,  or  (c)  material  diminution  in  the  Participant’s  position,  duties,  reporting
relationship or authority, which in any case is not cured within thirty (30) business days after written notice thereof by you to the
Board (which notice must be provided by you to the Company within 90 days following the initial occurrence of such event) and an
opportunity to cure within the notice period (the “Cure Period”). Resignation by the Participant following the Employer’s cure or
before  the  expiration  of  the  Cure  Period  will  constitute  a  voluntary  resignation  and  not  a  termination  or  resignation  for  Good
Reason  and  will  not  entitle  the  Participant  to  any  benefits  under  this  Plan.  Any  termination  on  account  of  a  Good  Reason
Resignation must occur within 120 days following the initial occurrence of such event.

4.    Dividend Equivalents. If the Company pays any cash dividend on its outstanding Common Stock for which the record
date occurs after the Date of Grant, the Administrator will credit the Restricted Stock Unit Account as of the dividend payment date
in an amount equal to the amount of the dividend paid by the Company on a single Share multiplied by the number of Restricted
Stock  Units  under  this  Agreement  that  are  unvested  (based  on  the  Target  Number  of  Restricted  Stock  Units  Granted)  as  of  that
record date and such number of Restricted Stock Units that are vested but have not been settled under the payment terms of Section
5  (“Dividend  Equivalents”).  Except  as  otherwise  provided  in  Section  3,  Dividend  Equivalents  will  vest  and  be  paid  to  the
Participant  on  the  dividend  payment  date  if  Participant  is  in  Continuous  Service  on  the  dividend  payment  date  declared  by  the
Company.

5.        Payment/Settlement.  Subject  to  Participant’s  satisfaction  of  the  applicable  withholding  requirements  pursuant  to
Section 7 hereof, the Company will settle the Award on the Payment/Settlement Date or Dates set forth in the Certificate by issuing
to Participant one share of Common Stock for each Restricted Stock Unit payable on that Payment/Settlement Date (and upon such
settlement, the Restricted Stock Units will cease to be credited to the Restricted Stock Unit Account). If the Certificate does not
specify  a  Payment/Settlement  Date,  the  applicable  Payment/Settlement  Date  will  be  the  date  within  10  business  days  after  the
Compensation  Committee  of  the  Board  has  made  the  certification  required  under  Plan  Section  7.2(d)  with  respect  to  the
performance  goals  applicable  to  such  Restricted  Stock  Units  following  the  date  of  publication  of  the  Corporation's  quarterly
earnings statement for the twelfth (12th) full quarter following the commencement of the Performance Period (which in any event
will be no later than March 15 of the calendar year following the date such performance goals are achieved). If an Acceleration
Event  occurs,  the  Payment/Settlement  Date  will  be  the  date  the  Acceleration  Event  occurs.  The  Administrator  will  enter
Participant’s  name  as  a  stockholder  of  record  with  respect  to  such  shares  of  Common  Stock  on  the  books  of  the  Company  with
respect  to  the  shares  of  Common  Stock  issued  on  that  Payment/Settlement  Date  free  of  all  restrictions  hereunder,  except  for
applicable federal and state securities law restrictions. Participant acknowledges and agrees that shares of Common Stock may be
issued in electronic form as a book entry with the Company’s transfer agent and that no physical certificates need be issued. Any
securities, other property or amounts nominally credited to the Restricted Stock Unit Account other than Restricted Stock Units will
be paid in kind or, in the Administrator’s discretion, in cash. Except as otherwise provided in Section 3, Dividend Equivalents will
vest and be paid to the Participant on the dividend payment date if Participant is in Continuous Service on the dividend payment
date declared by the Company. To the extent that a Service Agreement provides for acceleration of vesting of any or all unvested
Restricted Stock Units on termination of Continuous Service, such provisions are incorporated by reference in this Agreement.

6.        Compliance  with  Laws  and  Regulations.  The  issuance  and  transfer  of  shares  of  Common  Stock  on  any
Payment/Settlement Date will be subject to the Company’s and Participant’s full compliance, to the satisfaction of the Company
and its counsel, with all applicable requirements of federal, state, and foreign securities laws and with all applicable requirements
of  any  securities  exchange  on  which  the  Common  Stock  may  be  listed  at  the  time  of  such  issuance  or  transfer.  Participant
understands that the Company is under no obligation to register or qualify the shares of Common Stock with the U.S. Securities and
Exchange Commission (“SEC”), any state securities commission, foreign securities regulatory authority, or any securities exchange
to effect such compliance.

7.    Tax Withholding.

7.1    As a condition to payment under Section 5 hereof, Participant agrees that on or before the date as of which any
portion of the Restricted Stock Units vest, Participant will pay to the Company any federal, state, or local taxes required by law to
be withheld with respect to the Restricted Stock Units for which the restrictions lapse and any related securities, other property or
amounts then nominally credited to the Restricted Stock Unit Account.

7.2    Participant will pay the amounts due under this Section 7 to the Company. Such amounts will be paid by Stock
Withholding, or may be paid at Participant’s election, in cash, or (to the extent any applicable insider trading policy, window or
restriction  does  not  prohibit  Participant  from  engaging  in  a  sale  transaction)  by  tendering  shares  of  Common  Stock  held  by
Participant to a broker selected by the Company for immediate sale and remittance of proceeds equal to the required withholding
amount  to  the  Company,  including  shares  that  otherwise  would  be  issued  and  transferred  to  Participant  as  payment  on  the
applicable Payment/Settlement Date, with a Fair Market Value on that Payment/Settlement Date that does not exceed the maximum

statutory tax rates in the applicable jurisdictions (subject to Participant’s written request to withhold more than the required regular
tax withholding in the applicable jurisdictions), or a combination of cash and shares of Common Stock. If Participant fails to make
such payments, the Company or its Affiliates will, to the extent permitted by law, have the right to deduct from any payment of any
kind otherwise due to Participant any federal, state, or local taxes required by law to be withheld with respect to such payment.
Dividend Equivalents credited to the Restricted Stock Unit Account will be subject to withholding at the time of payment.

8.       Not Transferrable. Until  the  applicable  Payment/Settlement  Date,  the  Restricted  Stock  Units,  any  related  Dividend
Equivalents credited to the Restricted Stock Unit Account and any related securities, other property or amounts nominally credited
to the Restricted Stock Unit Account may not be sold, transferred, or otherwise disposed of, and may not be pledged or otherwise
hypothecated other than by will or by the applicable laws of descent and distribution, provided that the Restricted Stock Units and
any related Dividend Equivalents credited to the Restricted Stock Unit Account will remain subject to the terms of the Plan, the
Certificate and this Agreement.

9.    No Right to Continued Service. Nothing in this Agreement or in the Plan imposes or may be deemed to impose, by
implication or otherwise, any limitation on any right of the Company or any Affiliate to terminate Participant’s Continuous Service
at any time.

10.    Participant’s Representations and Warranties. Participant represents and warrants to the Company that Participant
has received a copy of the Plan, has read and understands the terms of the Plan, the Certificate, and this Agreement, and agrees to
be  bound  by  their  terms  and  conditions.  Participant  acknowledges  that  there  may  be  tax  consequences  upon  the  payment  of  the
Restricted Stock Units, payment of any Dividend Equivalents credited to the Restricted Stock Unit Account or disposition of any
shares  of  Common  Stock  received  on  a  Payment/Settlement  Date,  and  that  Participant  should  consult  a  tax  advisor  before  such
time.  Participant  agrees  to  sign  such  additional  documentation  as  the  Company  may  reasonably  require  from  time  to  time.
Participant  acknowledges  that  he  or  she  is  aware  that  copies  of  the  Plan  document  and  the  Company’s  financial  statements  and
information heretofore filed by the Company with the Securities and Exchange Commission (the “SEC”) are available upon request
to the Company, at the SEC’s Public Reference Room at 100 F Street, N.E., Room 1580, Washington, D.C. 20549, or by visiting
the SEC Internet site at http://www.sec.gov that contains reports, proxy and information statements and other information regarding
registrants that file electronically with the SEC.

11.    No Interest in Company Assets. All amounts nominally credited to Participant’s Restricted Stock Unit Account under
this Agreement will continue for all purposes to be part of the general assets of the Company. Participant’s interest in the Restricted
Stock Unit Account will make Participant only a general, unsecured creditor of the Company.

12.    No Stockholder Rights before Delivery. Participant will not have any right, title, or interest in, or be entitled to vote
or to receive distributions in respect of, or otherwise be considered the owner of, any of the shares of Common Stock covered by
the Restricted Stock Units until the Payment/Settlement Dates specified in the Certificate at which such shares of Common Stock
are issued pursuant to Section 5 hereof.

13.    Modification. The Agreement may not be amended or otherwise modified except in writing signed by both parties.

14.    Interpretation. Any dispute regarding the interpretation of this Agreement must be submitted by Participant or the
Company to the Administrator for review. The resolution of such a dispute by the Administrator will be final and binding on the
Company and Participant.

15.    Entire Agreement. The Plan and the Certificate are incorporated herein by reference. This Agreement, the Certificate,
and the Plan constitute the entire agreement of the parties and supersede all prior undertakings and agreements with respect to the
subject matter hereof. If any inconsistency or conflict exists between the terms and conditions of this Agreement, the Certificate,
and the Plan, the Plan will govern.

16.    Successors and Assigns. The Company may assign any of its rights under this Agreement. This Agreement will bind
and inure to the benefit of the successors and assigns of the Company. Subject to the restrictions on transfer set forth herein, this
Agreement  is  binding  upon  Participant  and  Participant’s  heirs,  executors,  administrators,  legal  representatives,  successors,  and
assigns.

17.        Governing  Law.  This  Agreement  will  be  governed  by  and  construed  in  accordance  with  the  laws  of  the  State  of
Delaware without giving effect to its conflict of law principles. If any provision of this Agreement is determined by a court of law
to be illegal or unenforceable, then such provision will be enforced to the maximum extent possible and the other provisions will
remain fully effective and enforceable.

SENIOR MANAGEMENT SEVERANCE PLAN

Effective as of February 20, 2020

Diamondback  Energy,  Inc.,  a  Delaware  corporation  (“Company”),  pursuant  to  the  authorization  of  the  Compensation
Committee of the Board, hereby adopts this Diamondback Energy, Inc. Senior Management Severance Plan (the “Plan”) to provide
certain severance pay benefits to Eligible Senior Executives who experience an Eligible Termination, in each case, under the terms
and conditions provided herein.

ARTICLE 1 
PURPOSE AND SCOPE

Section 1.1    Introduction. The Plan is being adopted pursuant to the authorization of the Compensation Committee of the

Board for the benefit of certain Eligible Senior Executives of the Company or any other adopting Employer.

Section  1.2        Purpose.  The  purpose  of  the  Plan  is  to  provide  severance  pay  benefits  under  the  terms  and  conditions
specified in Article 2 and Article 3 to Eligible Senior Executives who are subject to an Eligible Termination. The severance pay
benefits provided hereunder are not required by law and nothing herein creates an obligation to pay severance pay benefits of any
kind or amount, except as provided by this Plan. No other employee of the Company, an Affiliate, an Employer or any other Person
shall have any rights to benefits under this Plan.

Section 1.3    Plan Status. For tax purposes and for purposes of Title I of ERISA, this Plan document is intended to be
governed  by  ERISA  as  both  an  unfunded  “employee  welfare  benefit  plan”  within  the  meaning  of  Section  3(l)  of  ERISA  and  a
“pension  plan”  within  the  meaning  of  Section  3(2)  of  ERISA  that  is  an  unfunded  plan  maintained  primarily  for  the  purpose  of
providing  deferred  compensation  for  a  select  group  of  management  or  highly  compensated  employees,  and  shall  be  interpreted
accordingly.  This  document  is  intended  to  serve  as  both  the  plan  document  and,  together  with  the  additional  information  in
Appendix A, the summary plan description for the Plan.

ARTICLE 2 
ELIGIBILITY FOR SEVERANCE BENEFITS

Section 2.1    Payments and Benefits upon an Eligible Termination (Unrelated to a Change in Control). Subject to the
further provisions of this Article 2 and the Participant’s continued compliance with his or her obligations under Article 3 hereof,
upon a Participant’s Eligible Termination (other than on account of death or Disability) that does not occur within the Protection
Period:

(a)        Accrued  Obligations.  The  Employer  will  pay  or  provide  to  the  Participant,  the  Participant’s  Accrued

Obligations, including any payments required by applicable law;

(b)    Prior Year Unpaid Bonus Payment Amount. The Employer will pay an amount, if any, equal to the bonus that
would be payable for services attributable to a completed prior year performance period that, as of the Termination Date, has not
been paid under the terms of the Diamondback Energy, Inc. 2014 Executive Annual Incentive Compensation Plan, or any

successor  thereto.  The  prior  year  bonus  payment  amount  will  be  paid  after,  and  only  to  the  extent,  it  is  certified  by  the
Compensation Committee of the Board, and will be paid at the same time bonuses to similarly situated executives are paid, as if the
terminated Participant continued to be employed on the certification and bonus payment dates;

(c)    Base Salary Continuation. For each month during the period following the Termination Date that applies to the
Participant as specified in Schedule A, the Employer will continue to pay to the Participant an amount equal to the product of (i) his
or  her  monthly  base  salary,  as  in  effect  immediately  prior  to  the  Eligible  Termination  (or  immediately  prior  to  any  event
constituting  Good  Reason,  if  applicable),  multiplied  by  (ii)  the  multiple  specified  in  Schedule  A  that  is  applicable  to  such
Participant. The Base Salary Continuation amount will be payable in substantially equal periodic installments commencing on the
Payment Date in accordance with the normal payroll practices of the Employer;

(d)    Pro-rated Target Annual Bonus. To the extent not paid or payable under the terms of the Diamondback Energy,
Inc. 2014 Executive Annual Incentive Compensation Plan, or any successor thereto, Employer will pay to the Participant a lump
sum  amount  in  cash  equal  to  the  Participant’s  target  annual  bonus  for  the  year  that  includes  the  Termination  Date  pro-rated  to
reflect the number of days that the Participant was employed by an Employer or an Affiliate during such calendar year. Such pro-
rated target annual bonus amount will be payable on the Payment Date;

(e)        Group  Health  Plan  Premiums.  Provided  that  the  Participant  timely  and  properly  elects  and  continues  to  be
eligible for group health plan continuation coverage under COBRA for himself and/or his eligible dependents under an adopting
Employer’s or an Affiliate’s group health plans, the Employer will reimburse the Participant on a monthly basis for the premium
cost  of  such  COBRA  continuation  coverage  during  the  Continuation  Period.  Subject  to  the  Participant  submitting  adequate
substantiation  of  payment  of  the  applicable  COBRA  premiums,  the  reimbursements  will  commence  on  the  Payment  Date  and
continue  on  a  monthly  basis  for  the  remainder  of  the  Continuation  Period,  but  not  more  than  18  months  following  the
commencement thereof;

(f)        Equity  Awards.  Except  as  otherwise  set  forth  in  a  Participation  Agreement  between  the  Company  and  a
Participant, each outstanding unvested equity-based compensation award granted by the Company or an Affiliate that is held by or
for the Participant will be forfeited or vested, as applicable, in accordance with the applicable equity award agreement. Any vested
awards will be settled, based on the vesting, forfeiture and settlement terms of the applicable equity award agreements.

Section 2.2    Severance Benefits upon an Eligible Termination (Related to a Change in Control). Subject to the further
provisions of this Article 2, upon a Participant’s Qualifying Termination (other than on account of death or Disability) that occurs
within the Protection Period, the Participant will receive all of the payments and benefits described in Section 2.1 above, except
that the following substitution and modification will be made:

(a)    Lump Sum Compensation Payment. In lieu of any Base Salary Continuation payment under Section 2.1(c), the

Employer will pay to the Participant an amount in cash equal to the product of:

2

(i)    the  sum  of  (A)  the  Participant’s  annualized  base  salary  as  in  effect  immediately  prior  to  the  Eligible
Termination  (or  immediately  prior  to  any  event  constituting  Good  Reason,  if  applicable),  plus  (B)  the  Average  Annual
Bonus amount in effect immediately preceding the Termination Date; multiplied by

(ii)    the Applicable Factor specified in Schedule B that applies to the Participant.

(b)    Payment Timing. The lump sum compensation payment amount determined in Section 2.2(a) will be paid in a

single lump sum on the Payment Date.

Section  2.3        Payments  upon  a  Termination  of  Employment  Due  to  Death  or  Disability.  Subject  to  the  further

provisions of this Article 2, upon a Participant’s Eligible Termination due to death or Disability:

(a)    Accrued Obligations. The Employer will pay or provide to the Participant or his or her Personal representative

or estate, the Participant’s Accrued Obligations.

(b)    Prior Year Unpaid Bonus Payment Amount. The Employer will pay to the Participant or his or her Personal
representative or estate an amount, if any, equal to the bonus that would be payable for services attributable to a completed prior
year performance period that, as of the Termination Date, has not been paid under the terms of the Diamondback Energy, Inc. 2014
Executive Annual Incentive Compensation Plan, or any successor thereto. The prior year bonus payment amount will be paid after,
and only to the extent, it is certified by the Compensation Committee of the Board, and will be paid at the same time bonuses to
similarly  situated  executives  are  paid,  as  if  the  terminated  Participant  continued  to  be  employed  on  the  certification  and  bonus
payment dates;

(c)    Base Salary Continuation. For each month during the period following the Termination Date that applies to the
Participant as specified in Schedule A, the Employer will continue to pay to the Participant or his or her Personal representative or
estate an amount equal to the product of (i) his or her monthly base salary, as in effect immediately prior to the Eligible Termination
(or immediately prior to any event constituting Good Reason, if applicable), multiplied by (ii) the multiple specified in Schedule A
that  is  applicable  to  such  Participant.  The  Base  Salary  Continuation  amount  will  be  payable  in  substantially  equal  periodic
installments commencing on the Payment Date in accordance with the normal payroll practices of the Employer;

(d)    Pro-rated Target Annual Bonus. To the extent not paid or payable under the terms of the Diamondback Energy,
Inc. 2014 Executive Annual Incentive Compensation Plan, or any successor thereto, Employer will pay to the Participant or his or
her  Personal  representative  or  estate  a  lump  sum  amount  in  cash  equal  to  the  Participant’s  target  annual  bonus  for  the  year  that
includes  the  Termination  Date  pro-rated  to  reflect  the  number  of  days  that  the  Participant  was  employed  by  an  Employer  or  an
Affiliate during such calendar year. Such pro-rated target annual bonus amount will be payable on the Payment Date;

(e)        Equity  Awards.  Except  as  otherwise  set  forth  in  a  Participation  Agreement  between  the  Company  and  a
Participant, each outstanding unvested equity-based compensation award granted by the Company or an Affiliate that is held by or
for  the  Participant  will  be  forfeited  or  vested,  as  applicable,  in  accordance  with  the  terms  of  the  applicable  equity  award
agreements. Any vested awards will be settled, based on the vesting, forfeiture and settlement terms of the applicable equity award
agreements.

Section 2.4    Release and Full Settlement; Payment Delay; Repayment Obligations.

(a)    Release and Full Settlement. Any provision of this Plan to the contrary notwithstanding, the payment of any
amounts or provision of any benefits under Section 2.1, Section 2.2, Section 2.3 or Section 3.2 will be subject to the Participant’s
(or, if applicable, his Personal representative or estate’s) execution, within forty five (45) days following receipt (or such shorter
period as set forth in such release), of a waiver and general release of claims in the form provided by the Administrator, and such
waiver  and  general  release  of  claims  becoming  effective  and  irrevocable  in  accordance  with  its  terms  within  sixty  (60)  days
following the Termination Date.

(b)    Payment Timing. Except as set forth in the following sentence, any payments pursuant to Section 2.1, Section
2.2, Section 2.3 or Section 3.2 that would otherwise be payable in the first sixty (60) days following the Termination Date will be
withheld  and  any  unpaid  installments  will  become  payable  in  a  lump  sum  on  the  date  that  is  sixty  (60)  days  following  the
Termination  Date.  However,  if  the  Participant  is  a  Specified  Employee,  any  payments  hereunder  that  constitute  a  “deferral  of
compensation” within the meaning of Section 409A and to which the Participant would otherwise be entitled during the first six
months following the Termination Date will be accumulated and paid to the Participant on the date that is six months following the
Termination Date (or if earlier, to the Participant’s estate or Personal representative upon the Participant’s death).

(c)    Clawback or Forfeiture of Payments. The payment of any amounts or provision of any benefits under Section
2.1,  Section  2.2,  Section  2.3  or  Section  3.2  hereof  will  be  subject  to  the  Participant’s  continued  compliance  with  his  or  her
Restrictive  Covenant  obligations  under  Article  3,  and,  in  the  event  of  any  breach  of  such  obligations  by  the  Participant,  the
Participant  agrees  to  promptly  repay  the  Employer  the  gross  amount  or  value  of  any  payments  or  benefits  provided  under  this
Article 2. Notwithstanding  any  provision  in  this  Plan  or  any  Participation  Agreement  to  the  contrary,  if  Participant  breaches  the

Restrictive  Covenant  Provisions  of  Article  3,  or  if  required  by  any  policy  of  the  Company,  the  Employer  or  an  Affiliate,  by  the
Dodd-Frank Wall Street Reform and Consumer Protection Act or the Sarbanes–Oxley Act of 2002 or by other applicable law in
effect as of the time that any benefit payment is paid hereunder, each Participant’s benefits under this Plan shall be conditioned on
repayment  or  forfeiture  in  accordance  with  such  applicable  laws,  policy,  or  any  relevant  provision  of  the  related  Participation
Agreement.  By  entering  into  a  Participation  Agreement  and  becoming  a  Participant  under  this  Plan,  a  Participant  will  have
consented to any such clawback, repayment or forfeiture condition, regardless of whether or not such condition is expressly stated
in the Participation Agreement.

Section 2.5    Parachute Payments. Notwithstanding any other provisions of this Plan, in the event that any payment or
benefit  received  or  to  be  received  by  a  Participant  (including  any  payment  or  benefit  received  in  connection  with  a  Change  in
Control or the termination of a Participant’s employment during the Protected Period, whether pursuant to the terms of this Plan or
any other plan, arrangement or agreement) (all such payments and benefits, including the payments and benefits under this Plan,
being hereinafter referred to as the “Total Payments”) would be subject (in whole or part), to the excise tax imposed under Section
4999 of the Code (the “Excise Tax”), then, after taking into account any reduction in the Total Payments provided by reason of
Section 280G of the Code in such other plan, arrangement or agreement, the Total Payments shall be reduced, in the order set forth
below, to the extent necessary so that no portion of the Total Payments is subject to the Excise Tax, but only if (x) the net amount of
such Total Payments, as so reduced (and after subtracting the net amount of federal, state and local income taxes on such reduced
Total  Payments  and  after  taking  into  account  the  phase  out  of  itemized  deductions  and  Personal  exemptions  attributable  to  such
reduced Total Payments) is greater than or equal to (y) the net amount of such Total Payments without such reduction (but after
subtracting the net amount of federal, state and local income taxes on such Total Payments and the amount of Excise Tax to which
the  Participant  would  be  subject  in  respect  of  such  unreduced  Total  Payments  and  after  taking  into  account  the  phase  out  of
itemized deductions and Personal exemptions attributable to such unreduced Total Payments).

(a)        Total  Payments  Reduction.  The  Total  Payments  shall  be  reduced  by  the  Administrator  in  its  reasonable
discretion in the following order: (A) reduction of any cash severance payments otherwise payable that are exempt from Section
409A of the Code; (B) reduction of any other cash payments or benefits otherwise payable that are exempt from Section 409A of
the Code, but excluding any payments attributable to the acceleration of vesting or payments with respect to any stock option or
other equity award with respect to Company’s or an Affiliate’s common stock or other form of equity award that are exempt from
Section 409A of the Code; (C) reduction of any other payments or benefits otherwise payable to you on a pro-rata basis or such
other manner that complies with Section 409A of the Code, but excluding any payments attributable to the acceleration of vesting
and payments with respect to any stock option or other equity award with respect to Company’s or an Affiliate’s common stock or
other form of equity award that are exempt from Section 409A of the Code; and (D) reduction of any payments attributable to the
acceleration  of  vesting  or  payments  with  respect  to  any  stock  option  or  other  equity  award  with  respect  to  Company’s  or  an
Affiliate’s  common  stock  or  other  equity  interest  that  are  exempt  from  Section  409A  of  the  Code;  provided,  however,  that  no
reduction of a payment or benefit of nonqualified deferred compensation that is subject to Section 409A of the Code shall be made
to the extent that such reduction would result in any other payment or benefit being deemed a substitute (within the meaning of
Section  1.409A-3(f)  of  the  Treasury  Regulations)  for  the  forfeited  amount  by  reason  of  such  other  payment  or  benefit  having  a
different time or form of payment.

(b)    Performance of Calculations. For purposes of determining whether and the extent to which the Total Payments
will be subject to the Excise Tax, (A) no portion of the Total Payments the receipt or enjoyment of which a Participant has waived
at such time and in such manner as not to constitute a “payment” within the meaning of Section 280G(b) of the Code shall be taken
into  account;  (B)  no  portion  of  the  Total  Payments  shall  be  taken  into  account  which,  in  the  written  opinion  of  independent
accountants  of  nationally  recognized  standing  (“Accounting  Firm”)  selected  by  Company,  does  not  constitute  a  “parachute
payment” within the meaning of Section 280G(b)(2) of the Code (including by reason of Section 280G(b)(4)(A) of the Code) and,
in calculating the Excise Tax, no portion of such Total Payments shall be taken into account which, in the opinion of Accounting
Firm,  constitutes  reasonable  compensation  for  services  actually  rendered,  within  the  meaning  of  Section  280G(b)(4)(B)  of  the
Code, in excess of the Base Amount (as defined in Section 280G(b)(3) of the Code) allocable to such reasonable compensation; and
(C) the value of any non-cash benefit or any deferred payment or benefit included in the Total Payments shall be determined by the
Accounting Firm in accordance with the principles of Sections 280G(d)(3) and (4) of the Code.

(c)    Cooperation. If applicable, Participant, Company and Affiliates will each provide the Accounting Firm access
to and copies of any books, records and documents in their respective possession, reasonably requested by the Accounting Firm,
and  otherwise  cooperate  with  the  Accounting  Firm  in  connection  with  the  preparation  and  issuance  of  the  determinations  and
calculations contemplated by this Section 2.5. The fees and expenses of the Accounting Firm for its services in connection with the
determinations and calculations contemplated by this Section 2.5 will be borne by Company.

(d)        No Gross-Ups. None  of  the  Company,  any  Affiliate  or  any  Employer  is  obligated  to  provide  a  gross-up  or

similar payment to any Participant who is subject to Excise Tax on the Total Payments.

Section  2.6        Coordination  with  Certain  Other  Agreements.  The  benefits  under,  and  participation  in,  this  Plan  are
intended to supersede and replace the severance and separation benefits to which an Participant may be entitled under any other
plan, policy, agreement or arrangement. By executing a Participation Agreement with the Company to participate in this Plan, an
Eligible Senior Executive will waive any right to severance or separation benefits under any other severance or separation benefits
plan, policy, agreement or arrangement of any Employer.

Section 2.7    No Mitigation. A Participant will not be required to mitigate the amount of any payment or benefit provided
for  in  this  Article  2  or  Section  3.2  by  seeking  other  employment  or  otherwise,  nor  will  the  amount  of  any  payment  or  benefit
provided for in this Article 2 or Section 3.2 be reduced by any compensation or benefit earned by the Participant as the result of
employment by another employer.

Section 2.8    Deductions from Severance Benefits. The following items will be deducted from the benefits paid under the

Plan:

withhold;    

Employer; and

(a)        All  Federal,  State  and  local  taxes  that  the  Administrator  determines  the  Plan  must  or  may  deduct  or

(b)        To  the  extent  permitted  by  law,  any  amounts  a  Participant  owes  to  the  Company,  any  Affiliate  or  any

(c)    Any amount of garnished earnings which are required to be withheld from the Participant’s pay, if Employer

has been garnishing the Participant’s earnings pursuant to an order of garnishment, child support or tax lien.

ARTICLE 3 
RESTRICTIVE COVENANTS

Section 3.1    Non-Competition and Non-Solicitation Obligations. In consideration of the payments and benefits that may
be paid or provided to the Participant hereunder and to protect the trade secrets and confidential information of the Company and
its Affiliates that have been and will in the future be disclosed or entrusted to the Participant, the business goodwill of the Company
or its Affiliates, and the business opportunities that have been and will in the future be disclosed or entrusted to the Participant by
the Company or its Affiliates, the Company and the Participant agree to the provisions of this Article 3. The Participant agrees that
during the Restricted Period, the Participant will not:

(a)    Non-Competition. Without the written consent of the Compensation Committee of the Board, at any time or in
any  manner,  either  directly  or  indirectly,  become  associated  with,  render  services  to,  invest  in,  represent,  advise  or  otherwise
participate  as  an  officer,  employee,  director,  stockholder,  partner,  member,  agent  of  or  consultant  for  any  company,  business,
organization or other legal or natural person that engages or participates in the Restricted Business; provided, however, that nothing
herein  shall  prevent  a  Participant  from  acquiring  up  to  two  percent  (2%)  of  the  securities  of  any  company  listed  on  a  national
securities exchange or quoted on the NASDAQ quotation system, provided Participant’s involvement with any such company is
solely that of a passive stockholder. The covenant contained in this Section 3.1(a) shall be deemed a series of separate covenants for
each  state,  county  and  city  in  which  the  Diamondback  Parties’  business  is  conducted  or  is  preparing  to  be  conducted.  If, in any
judicial proceeding, a court shall refuse to enforce all of the separate covenants deemed included in this Section 3.1(a) because,
taken  together,  they  cover  too  extensive  a  geographic  area,  the  parties  intend  that  those  covenants  (taken  in  order  of  the  states,
counties  and  cities  therein  which  are  least  populous),  which  if  eliminated  would  permit  the  remaining  separate  covenants  to  be
enforced in such proceeding, shall, for the purpose of such proceeding, be deemed eliminated from the provisions of this Section
3.1(a).

(b)    Non Solicitation, Non Hire of Employees. At any time or in any manner, either directly or indirectly, either on
Participant’s  behalf  or  on  behalf  of  any  Person  (other  than  the  Diamondback  Parties),  recruit,  solicit,  hire,  divert  or  otherwise
encourage or attempt to recruit, solicit, hire, divert or otherwise encourage any officer or employees or agents of any Diamondback
Party  to  enter  into  any  employment,  consulting  or  advisory  arrangement  or  contract  with  or  to  perform  any  services  for  or  on
Participant’s  behalf  or  on  behalf  of  any  Person  (other  than  a  Diamondback  Party),  or  to  enter  into  any  kind  of  business  with
Participant or any other Person, including, without limitation, any Restricted Business.

(c)    Non-Interference. At any time or in any manner, either directly or indirectly, for the Participant’s own account
or for the account of any other Person, interfere with any Diamondback Party’s relationship with any of its land owners, mineral
owners, gatherers, processors, employees, contractors, suppliers or regulators or any other third party with which a Diamondback
Party maintains a business relationship.

Section 3.2    Limitations on Non-Competition. Notwithstanding the provisions of Section 3.1, if the Participant provides
written notice to the Employer that the Participant will terminate employment with the Employer pursuant to a resignation by the
Participant that does not constitute an Eligible Termination, then, solely for purposes of Section 3.1(a), the Restricted Period will
end  on  a  date  selected  by  the  Company  and  set  forth  in  a  written  notice  provided  by  the  Company  to  the  Participant;  provided,
however, that (a) the date selected by the Company will be a whole number of months (not in excess of 12) after the Termination
Date  and  (b)  subject  to  the  provisions  of  Section  2.4  hereof,  beginning  on  the  Payment  Date,  the  Employer  will  pay  to  the
Participant an amount equal to one-twelfth of the Participant’s annualized base salary plus target annual bonus for each month of
the Restricted Period, which amount will be paid on a prorated basis on each regularly scheduled payroll date during the Restricted
Period following the Termination Date. The Participant hereby delegates to the Company the right to select and determine in good
faith the duration of the Restricted Period as provided in this Section 3.2.

Section 3.3    Non-Disparagement. During and following the Participant’s employment with the Employer, the Participant
agrees  not  to  make  public  statements,  negative  comments  or  otherwise  disparage  any  Diamondback  Party  or  any  Diamondback
Party’s officers, directors, employees, agents, shareholders or other equity holders in any manner harmful to them or their business,
business reputation or personal reputation. The foregoing shall not be violated by truthful statements in response to legal process,
required governmental testimony or filings, or administrative or arbitral proceedings (including, without limitation, depositions in
connection with such proceedings).

Section 3.4    Return of Property. All materials, records and documents in any medium made by a Participant or coming
into a Participant’s possession during employment concerning any products, processes or services, manufactured, used, developed,
investigated,  provided  or  considered  by  any  Diamondback  Party  or  otherwise  concerning  the  business  or  affairs  of  the
Diamondback  Parties,  are  the  sole  property  of  the  applicable  Diamondback  Party,  and  upon  termination  of  a  Participant’s
employment,  or  upon  request  of  the  Company  during  employment,  a  Participant  will  promptly  deliver  the  same  to  the
Diamondback Party designated by the Company. In addition, upon termination of employment, or upon request of the Company
during  a  Participant’s  employment,  the  Participant  will  deliver  to  the  Diamondback  Party  designated  by  the  Company  all  other
property  of  the  Diamondback  Parties  in  Participant’s  possession  or  under  Participant’s  control,  including,  but  not  limited  to,
confidential or proprietary data or information, financial statements, marketing and sales data, drawings, documents and electronic
records.

Section  3.5        Cooperation.  Upon  the  receipt  of  reasonable  notice  from  the  Company,  an  Employer  or  an  Affiliate
(including outside counsel), a Participant agrees that while employed by any Diamondback Party and thereafter, the Participant will
provide reasonable assistance to any Diamondback Party and their respective representatives in defense of any claims that may be
made against any Diamondback Party and will assist any Diamondback Party in the prosecution of any claims that may be made by
any Diamondback Party, to the extent that such claims relate to the period of participant’s employment with a Diamondback Party.
Participants agree to promptly inform the Company if they become aware of any lawsuits involving such claims that may be filed
or  threatened  against  any  Diamondback  Party.  Participants  also  agree  to  promptly  inform  the  Company  (to  the  extent  legally
permitted to do so) if asked to assist in any investigation of any Diamondback Party (or its actions), regardless of whether a lawsuit
or other proceeding has then been filed against any Diamondback Party with respect to such investigation. Upon presentation of
appropriate  documentation,  the  Company  or  an  Employer  will  pay  or  reimburse  the  Participant  for  all  reasonable,  out-of-pocket
expenses incurred in complying with this Section 3.5. If at the time of compliance Participant is no longer an employee, officer or
director (or functional equivalent) of any Diamondback Party, the Company or an Employer will provide a reasonable per diem.

Section 3.6    Confidential Information.

(a)    Confidentiality. In the course of employment with the Diamondback Parties, a Participant will have had, and/or
will have, access to confidential or proprietary data or information of the Diamondback Parties. Each Participant hereby agrees to
not at any time during or after employment divulge or communicate to any Person (which term, for purposes of this Plan, includes
both individual Persons or entities) nor shall a Participant direct any employee of a Diamondback Party to divulge or communicate
to  any  Person  (other  than  to  a  Person  bound  by  confidentiality  obligations  similar  to  those  contained  herein  and  other  than  as
necessary in performing your duties hereunder), or use to the detriment of the Diamondback Parties or for the benefit of any other
Person, any of such data or information. No business conducted by a Participant or any organization of which a Participant, directly
or indirectly, is an owner, partner, manager, joint venturer, director, officer, manager or otherwise a participant in or connected with
in any locality, state or country in which the Diamondback Parties conduct business may use any name, designation or logo which
is  substantially  similar  to  that  presently  used  by  any  Diamondback  Party.  The  term  “confidential  or  proprietary  data  or
information”  as  used  in  this  Plan  means  any  information  not  generally  available  to  the  public  or  generally  known  within  the
applicable  Diamondback  Party’s  industry,  including,  without  limitation,  Personnel  information,  financial  information,  customer
lists or contacts, vendor lists and pricing information, strategy and plans, engineering data and analysis, maps, samples, well logs,
well production information, geological data, geophysical data, seismic data, information regarding operations, systems, services,
know-how,  computer  and  any  other  processed  or  collated  data,  trade  secrets  (including,  without  limitation,  software),  computer
programs, pricing, marketing and advertising data.

(b)    Proprietary Information and Disclosure. Each Participant agrees that they will at all times promptly disclose to
the Company, in such form and manner as the Company or an Employer may require, any inventions, improvements or procedural
or  methodological  innovations,  program  methods,  forms,  systems,  services,  designs,  marketing  ideas,  products  or  processes
(whether or not capable of being trademarked, copyrighted or patented) conceived or developed or created by the Participant during
or  in  connection  with  employment  with  any  Diamondback  Party  and  which  relate  to  the  business  of  any  Diamondback  Party
(“Intellectual Property”). Each Participant agrees that all such Intellectual Property constitutes a work-for-hire and will be the sole
property  of  the  applicable  Diamondback  Party.  Each  Participant  further  agrees  that  he  or  she  will  execute  such  instruments  and
perform such acts as may be requested by the Company or an Employer to transfer to and perfect in the entity designated by the
Company all legally protectable rights in such Intellectual Property.

ARTICLE 4 
CLAIMS AND APPEAL PROCEDURES

Section 4.1    Filing Claim for Benefits. If a Participant or Beneficiary (“Claimant”) believes he or she has not received
the  benefits  Claimant  is  entitled  to  receive  under  the  terms  of  the  Plan,  Claimant  may  file  a  claim  for  benefits  with  the

Administrator. All claims must be made in writing and must be signed by Claimant or an authorized representative. If Claimant
does  not  furnish  sufficient  information  to  determine  the  validity  of  the  claim,  the  Administrator  will  indicate  to  Claimant  any
additional information which is required.

Section 4.2    Notification by the Administrator. Each claim will be approved or disapproved by the Administrator within
90 days following the receipt of the information necessary to process the claim (45 days if the claim relates to a Plan determination
of  disability  (a  “Disability  Claim”)).  In  the  event  the  Administrator  denies  a  claim  for  benefits  in  whole  or  in  part,  the
Administrator  will  notify  Claimant  in  writing  or  by  electronic  notification  of  the  denial  of  the  claim.  Such  notice  by  the
Administrator  will  also  set  forth,  in  a  manner  calculated  to  be  understood  by  Claimant,  the  specific  reason  for  such  denial,  the
specific Plan provisions on which the denial is based, a description of any additional material or information necessary to perfect
the  claim  with  an  explanation  of  why  such  material  or  information  is  necessary,  and  an  explanation  of  the  Plan’s  claim  review
procedure as set forth in Section 4.3 and the time limits applicable to such procedures, including a statement of Claimant’s right to
bring  a  civil  action  under  Section  502  of  ERISA  following  a  claim  denial  after  review.  These  periods  may  be  extended  by  the
Administrator for up to 90 days (30 days in the case of a Disability Claim), if the Administrator determines that such an extension
is necessary due to matters beyond the control of the Plan and notifies Claimant, prior to expiration of the initial notification period,
of the circumstances requiring an extension of time and the date by which the Administrator expects to render a decision. In the
case of a Disability Claim, the Administrator may further extend the period for making a determination by up to an additional 30
days  if,  prior  to  the  end  of  the  first  30  day  extension  period,  the  Administrator  determines  that  such  an  additional  extension  is
necessary due to matters beyond the control of the Plan and notifies Claimant of the circumstances requiring an extension of time
and the date by which the Administrator expects to render a decision. If no action is taken by the Administrator on a claim within
90 days (45 days for a Disability Claim), the claim will be deemed to be denied for purposes of the review procedure, unless the
failure  was  a  de  minimis  violation  that  does  not  cause  and  is  not  likely  to  cause  prejudice  or  harm  to  Claimant  and  the
Administrator demonstrates that the failure was for good cause or due to matters beyond the control of the Administrator and that
the failure occurred in the context of an ongoing good faith exchange of information between the Plan and Claimant.

Section 4.3    Review Procedure. A Claimant may appeal a denial of his or her claim by requesting a review of the decision
by the Administrator or a Person designated by the Administrator, which Person will be a Named Fiduciary under Section 402(a)(2)
of  ERISA  for  purposes  of  this  Section  4.3.  An  appeal  must  be  submitted  in  writing  within  60  days  (180  days  in  the  case  of  a
Disability Claim) after the denial and must:

(a)    Request a review of the claim for benefits under the Plan;

(b)        Set  forth  all  of  the  grounds  under  which  Claimant’s  request  for  review  is  based  and  any  facts  in  support

thereof; and

(c)    Set forth any issues or comments which Claimant deems pertinent to the appeal.

In connection with an appeal, Claimant and his or her legal representative will be given the opportunity to:

(i)    submit written comments, documents, records, and other information relating to the claim for benefits;

(ii)        obtain  reasonable  access,  upon  request  and  free  of  charge,  to  review  and  obtain  copies  of  pertinent
documents  or  materials  upon  submission  of  a  written  request  to  the  Administrator  or  Named  Fiduciary,  provided  the
Administrator or Named Fiduciary finds the requested documents or materials are relevant to Claimant’s claim for benefits
within the meaning of claims procedure regulation 29 C.F.R. § 2560.503-1(m)(8).

On the basis of its review, the Administrator or Named Fiduciary will make an independent determination of Claimant’s eligibility
for benefits under the Plan. The review will take into account all comments, documents, records, and other information submitted
by Claimant relating to the claim for benefits, without regard to whether such information was submitted or considered in the initial
benefit claim determination. The Administrator or the Named Fiduciary designated by the Administrator will act upon each appeal
within  60  days  (45  days  in  the  case  of  a  Disability  Claim  appeal)  after  receipt  thereof,  unless  special  circumstances  require  an
extension of the time for processing, in which case a decision will be rendered as soon as possible, but not later than 120 days (90
days in the case of a Disability Claim appeal) after the appeal is received. The decision of the Administrator or Named Fiduciary on
any  claim  for  benefits  will  be  final  and  conclusive  upon  all  parties  thereto.  In  the  event  the  Administrator  or  Named  Fiduciary
denies an appeal in whole or in part, it will give written or electronic notice of the decision to Claimant within five days of the date
the determination is made, which notice will set forth in a manner calculated to be understood by Claimant the specific reasons for
such denial and which will make specific reference to the pertinent Plan provisions on which the decision was based. The notice
will also contain a statement that Claimant is entitled to receive upon request and free of charge, reasonable access to, and copies
of, all documents, records, and other information relevant to claimant’s claim for benefits, within the meaning of claims procedure
regulation 29 C.F.R. § 2560.503-1(m)(8) and a statement of Claimant’s right to bring a civil action under Section 502 of ERISA.

(d)    Effective for Disability Claims filed on or after the Effective Date, the following additional rules will apply:

4

(i)        Notice  to  Claimant  of  any  extension  of  the  45-day  period  for  initial  determination  must  include  the
circumstances  requiring  the  extension  and  the  date  as  of  which  a  decision  is  expected,  with  a  specific  explanation  of  the
standards  on  which  entitlement  to  a  disability  benefit  are  based,  the  unresolved  issues  preventing  a  decision  on  the
Disability  Claim  and  the  information  needed  to  resolve  those  issues,  and  must  give  Claimant  45  days  to  provide  any
information requested.

(ii)        In  addition  to  the  information  provided  with  respect  to  other  claims,  the  notification  of  denial  of  a

Disability Claim must include the following:

(A)    A discussion of the decision, including an explanation of the basis for disagreeing with or not
following the views presented by Claimant to the Plan of health care professionals who are treating the Participant
and vocational professionals who have evaluated the Participant; medical or vocational experts whose advice was
obtained on behalf of the Plan in connection with the Disability Claim, without regard to whether the advice was
relied on in making the determination; and any disability determination made by the Social Security Administration
presented to the Plan by Claimant.

(B)    Either the specific internal rules, guidelines, protocols, standards or other similar criteria of the
Plan relied on in making the decision, or a statement that such rules, guidelines, protocols, standards or other similar
criteria of the Plan do not exist.

(C)    A statement that Claimant may request, free of charge, reasonable access to and copies of all

documents, records and other information relevant to the Disability Claim.

(iii)    Subsequent review of any decision denying a Disability Claim must be conducted by an independent
and impartial fiduciary not involved in the initial determination. Claimant shall be notified in writing not later than
45  days  after  receipt  of  a  request  for  a  review.  This  45-day  period  may  be  extended  for  an  additional  45  days  if
special circumstances require the extension. Before the Plan can issue an adverse determination on appeal, Claimant
shall be provided, free of charge, with any new or additional evidence considered, relied on or generated by the Plan
administrator or other Person making the benefit determination (or at the direction of the Plan administrator or such
other  Person)  in  connection  with  the  Disability  Claim.  Such  evidence  shall  be  provided  to  Claimant  as  soon  as
possible and sufficiently before the deadline for the notice of adverse determination, to give Claimant a reasonable
opportunity to respond. Before the Plan can issue an adverse determination on appeal based on new or additional
rationale, Claimant shall be provided, free of charge, with such rationale. The rationale will be provided as soon as
possible and sufficiently before the deadline for the notice of adverse determination to give Claimant a reasonable
opportunity to respond.

(iv)    In addition to the information provided for all other claims on appeal, the notice of determination of a
Disability  Claim  appeal  must  include  an  explanation  of  the  basis  for  disagreeing  with  or  not  following  the  views
presented by Claimant of health care professionals treating the Participant and vocational professionals who

5

evaluated  the  Participant,  the  views  of  medical  or  vocational  experts  whose  advice  was  obtained  on  behalf  of  the
Plan administrator (regardless of whether the advice was relied upon), and any disability determination of the Social
Security  Administration  presented  by  Claimant  to  the  Plan  administrator.  The  notice  also  shall  include  either  the
specific internal rules, guidelines, protocols, standards or other similar criteria relied on in making the decision or a
statement  that  no  such  rules,  guidelines,  protocols,  standards  or  other  similar  criteria  exist,  and  a  statement
informing  Claimant  of  his  or  her  right  to  bring  a  civil  suit  under  federal  law  (and  a  description  of  the  Plan’s
limitation period for doing so, if any).

Section  4.4        Administrator’s  Authority.  As  provided  in  Section  5.1,  the  Plan  Administrator  has  the  discretionary
authority  to  interpret  the  Plan,  make  factual  findings  and  determinations  and  make  final  decisions  with  respect  to  paying  claims
under the Plan. All determinations of the Plan administrator shall be final, conclusive and binding on all interested parties, unless
the actions of the Plan Administrator are arbitrary and capricious.

ARTICLE 5 
PLAN ADMINISTRATION

Section 5.1    In General. The general administration of the Plan and the duty to carry out its provisions shall be vested in
the Administrator, which shall be the “plan administrator” as that term is defined in Section 3(16)(A) of ERISA. The Plan and the
severance benefits payable under the Plan shall be administered by the Administrator, which will be the Compensation Committee
of the Board or its delegate, unless otherwise appointed from time to time by the Board. The Administrator may, in its discretion,
secure  the  services  of  other  parties,  including  agents  and/or  employees  to  carry  out  the  day-to-day  functions  necessary  to  an
efficient operation of the Plan. The Administrator’s interpretations, decisions, requests and exercises of power and responsibilities
shall not be subject to review by anyone and shall be final, binding, and conclusive upon all Persons. The Administrator shall, in its
sole and absolute discretion, have the exclusive right to interpret all of the terms of the Plan, to determine eligibility for coverage
and benefits, to make reasonable and uniform rules and regulations required in the administration of the Plan, to resolve disputes as
to eligibility, type, or amount of benefits, to correct any errors or omissions in the form or operation of the Plan, to make such other
determinations with respect to the Plan, and to exercise such other powers and responsibilities as shall be provided for in the Plan
or  as  shall  be  necessary  or  helpful  with  respect  thereto.  The  Administrator  under  and  pursuant  to  this  Plan  shall  be  the  named
fiduciary  for  purposes  of  Section  402(a)  of  ERISA  with  respect  to  all  powers  and  duties  expressly  or  implicitly  assigned  to  it
hereunder.

Section 5.2    Reimbursement and Compensation. The  Administrator  shall  receive  no  compensation  for  its  services  as
Administrator, but it shall be entitled to reimbursement for all sums reasonably and necessarily expended by it in the performance
of such duties.

ARTICLE 6 
AMENDMENT AND TERMINATION

The Company, by action of the Compensation Committee of its Board, reserves the right to amend or terminate the Plan,
without the consent of any Person or entity. However, no such amendment may eliminate the right to receive severance benefits
which an Eligible Senior Executive has accrued or become entitled to under Article 2 of the Plan prior to the effective date of such
amendments  or  termination.  Such  amendment  or  termination  shall  be  effective  when  adopted  in  an  instrument  in  writing,  duly
executed  on  behalf  of  Company.  This  Plan  may  not  be  amended  on  or  following  a  Change  in  Control  to  adversely  affect  the
benefits or rights to benefits (contingent or otherwise) of any Participant under this Plan or terminated on or following a Change in
Control  until  there  are  no  longer  any  benefits  potentially  payable  under  this  Plan.  Further,  a  participating  Employer  may  not
terminate its participation in this Plan on or following a Change in Control unless and until it no longer employs any Participants
and has otherwise satisfied its obligations to pay benefits under this Plan.

ARTICLE 7 
CODE SECTION 409A

Section  7.1        Deferred  Compensation  Exceptions.  Payments  under  this  Plan  will  be  administered  and  interpreted  to
maximize the short-term deferral exception to and the involuntary separation pay exception under Section 409A of the Code and
the regulations thereunder (collectively “Section 409A”). The portion of any payment under this Plan that is paid within the short-
term  deferral  period  (within  the  meaning  of  Code  Section  409A  and  Treas.  Regs.  §1.409A-1(b)(4))  or  that  is  paid  within  the
involuntary  separation  pay  safe  harbor  (as  described  in  Code  Section  409A  and  Treas.  Regs.  §1.409A-1(b)(9)(iii))  will  not  be
treated as nonqualified deferred compensation and will not be aggregated with other nonqualified deferred compensation plans or
payments.

Section 7.2    Separate Payments and Payment Timing. Any payment or installment made under this Plan, any amount
that is paid as a short-term deferral, within the meaning of Treas. Regs. §1.409A-1(b)(4), and any payment within the involuntary
separation pay safe harbor exception in Treas. Regs. §1.409A-1(b)(9)(iii) will be treated as separate payments. Executive will not,
directly or indirectly, designate the taxable year of a payment made under this Plan, and if the release period discussed in Section
2.4 above spans two (2) calendar years, payment of any amounts that are subject to Section 409A shall be paid in the later calendar
year.  Payment  dates  provided  for  in  this  Plan  will  be  deemed  to  incorporate  grace  periods  that  are  treated  as  made  upon  a
designated  payment  date  within  the  meaning  of  Code  Section  409A  and  Treas.  Regs.  §1.409A-3(d).  The  Company  does  not
guaranty or warrant the tax consequences of this Plan and, except as specifically provided to the contrary in this Plan, each Eligible
Senior Executive, in all cases, will be liable for any taxes due as a result of this Plan. Neither the Company nor any of its Affiliates
shall have any obligation to indemnify or otherwise hold any Eligible Senior Executive harmless from any or all such taxes, interest
or penalties, or liability for any damages related thereto.

Section 7.3    General Section 409A Provisions. If for any reason, the short-term deferral or involuntary separation pay
plan exception is inapplicable, payments and benefits payable to any Participant under this Plan are intended to comply with the
requirements of Section 409A. To the extent the payments and benefits under this Plan are subject to Section 409A, this Plan will
be interpreted, construed and administered in a manner that satisfies the requirements of Sections 409A(a)(2), (3) and (4) of the
Code and the Treasury Regulations thereunder (and any applicable transition relief under Section 409A of the Code).

(a)    If  the  Company  determines  that  any  payments  or  benefits  payable  under  this  Plan  intended  to  comply  with
Sections 409A(a)(2), (3) and (4) of the Code do not comply with Section 409A of the Code, the Company may amend this Plan, or
take such other actions as the Company deems reasonably necessary or appropriate, to comply with the requirements of Section
409A  of  the  Code,  the  Treasury  Regulations  thereunder  (and  any  applicable  relief  provisions)  while  preserving  the  economic
agreement of the parties. If any provision of the Plan would cause such payments or benefits to fail to so comply, such provision
will not be effective and will be null and void with respect to such payments or benefits, and such provision will otherwise remain
in full force and effect.

(b)        All  payments  considered  nonqualified  deferred  compensation  under  Section  409A  and  the  regulations
thereunder will be made on the date(s) provided herein and no request to accelerate or defer any payment under this Section will be
considered  or  approved  for  any  reason  whatsoever,  except  as  permitted  under  Section  409A.  Notwithstanding  the  foregoing,
amounts payable hereunder which are not nonqualified deferred compensation, or which may be accelerated pursuant to Section
409A, such as distributions for applicable tax payments, may be accelerated, but not deferred, at the sole discretion of Company.

(c)    To the extent required to comply with Section 409A, all references in this Plan to termination of employment
or  termination  mean  an  Employee’s  “separation  from  service”  as  that  term  is  defined  in  Section  1.409A-1(h)  of  the  Treasury
Regulations.

Section 7.4    Specified Employee Status.

(a)    If a Participant is a specified employee (within the meaning of Code Section 409A) on the date of his or her
separation from service, any payments made with respect to such separation from service under this Plan, and other payments or

benefits under this Plan that are subject to Section 409A of the Code, will be delayed in order to comply with Section 409A(a)(2)
(B)(i) of the Code, and such payments or benefits will be paid or distributed to you during the five-day period commencing on the
earlier of: (i) the expiration of the six-month period measured from the date of Participant’s separation from service, or (ii) the date
of  Participant’s  death.  Upon  the  expiration  of  the  applicable  six-month  period  under  Section  409A(a)(2)(B)(i)  of  the  Code,  all
payments deferred pursuant to this Section 7.4 will be paid to Executive (or Executive’s estate, in the event of Executive’s death) in
a lump sum payment. Any remaining payments and benefits due under the Plan will be paid as otherwise provided in the Plan.

(b)    To minimize the risk that the six-month delay pursuant to the preceding paragraph will disrupt coverage under
any employee benefit plan in which Executive is entitled to participate following the termination of employment, payments that are
not considered deferred compensation because they are paid as a short-term deferral or are within the involuntary separation pay
safe harbor exception that are made during the six months following the termination of your employment shall first be applied to
cover  any  costs  relating  to  such  continued  employee  benefits  plan  coverage,  but  only  to  the  extent  that  such  coverage  would
constitute deferred compensation for purposes of Section 409A, and thereafter shall be made in respect of other amounts or benefits
owed to you.

ARTICLE 8 
MISCELLANEOUS INFORMATION

Section  8.1        Other  Participating  Employers.  The  Company  is  the  Plan  sponsor  and  Diamondback  E&P,  LLC  is  an
adopting Employer under this Plan. It is contemplated that other subsidiaries and Affiliates of the Company may adopt this Plan,
with  the  approval  of  the  Compensation  Committee  of  the  Board,  and  thereby  become  an  Employer  hereunder.  Any  such  entity,
whether  or  not  presently  existing,  may  become  an  Employer  by  appropriate  action  of  its  board  of  directors  or  non-corporate
counterpart. The provisions of this Plan will apply separately and equally to each Employer and its employees in the same manner
as  is  expressly  provided  for  the  Company  and  its  employees,  except  that  the  determination  of  whether  a  Change  in  Control  has
occurred  will  be  made  based  solely  on  the  Company.  Transfer  of  employment  among  the  Company  and  other  participating
Employers  will  not  be  considered  an  Eligible  Termination  hereunder  unless  such  transfer  otherwise  constitutes  a  Good  Reason
event. A sale of assets or other transaction where a Participant’s employment is transferred to a successor or acquiring entity and
there is no loss of employment will not be considered an Eligible Termination hereunder unless such transfer otherwise constitutes
a Good Reason event. Subject to the provisions of Article 6, any participating Employer may, by appropriate action of its board of
directors  or  non-corporate  counterpart,  terminate  its  participation  in  this  Plan.  Amounts  payable  hereunder  will  be  paid  by  the
Employer that employs the particular Participant.

Section 8.2    Limitation of Rights. Neither the establishment of the Plan nor any amendment thereof, nor the payment of
any benefits, will be construed as giving to any Participant, or other Person any legal or equitable right against Company, any of its
Affiliates,  or  any  Person  acting  on  behalf  of  Company  or  any  of  its  Affiliates,  except  as  expressly  provided  herein.  Likewise,
nothing appearing in or done pursuant to the Plan will be held or construed to create a contract of employment with any Participant
or to be consideration for the employment of any Participant. Nothing contained herein will be deemed to (a) give any person the
right to be retained in the employ of the Employer, (b) restrict the right of the Employer to discharge any Participant at any time, (c)
restrict  any  Participant’s  right  to  terminate  employment  at  any  time,  or  (d)  change  the  “at  will”  nature  of  the  employment
relationship between the Participant and the Employer.

Section 8.3    Governing Law. The provisions of the Plan shall be construed, enforced and administered according to the

laws of the State of Delaware, to the extent not preempted by ERISA and any otherwise applicable federal law.

Section 8.4    Jurisdiction and Venue. Exclusive jurisdiction and venue of all disputes arising out of or relating to this plan
shall  be  in  any  court  of  appropriate  jurisdiction  in  Midland,  Texas,  or  if  such  courts  do  not  have  jurisdiction  or  will  not  accept
jurisdiction,  in  any  court  of  general  jurisdiction  in  the  State  of  Texas.  All  parties  hereby  irrevocably  consent  to  the  exclusive
jurisdiction by any such court with respect to any such proceeding and hereby irrevocably waive, and agree not to assert, by way of
motion, as a defense, counterclaim or otherwise (a) any claim that he, she or it is not personally subject to the jurisdiction of the
above-named courts for any reason other than by failure to lawfully serve process, (b) that he, she or it or their property is exempt
or immune from the jurisdiction of any such court or from any legal process commenced in such courts, and (c) to the fullest extent
permitted by applicable law, that (i) the action or proceeding is brought in an inconvenient forum, (ii) the venue of such action or
proceeding is improper and (iii) this Plan or the subject matter thereof may not be enforced in or by such courts. The provisions of
this Section 8.4 shall survive and remain in effect until all obligations are satisfied, notwithstanding any termination of the Plan.

Section 8.5    Waiver of Trial by Jury. To the extent not prohibited by applicable law, each Participant under this Plan
hereby waives, and covenants that he or she shall not assert (whether as plaintiff, defendant or otherwise), their respective right to a
jury  trial  of  any  permitted  claim  or  cause  of  action  arising  out  of  this  Plan,  any  of  the  transactions  contemplated  hereby,  or  any
dealings  between  any  of  the  parties  hereto  relating  to  the  subject  matter  of  this  Plan  or  any  of  the  agreements  or  transactions
contemplated hereby. The scope of this waiver and covenant is intended to be all encompassing of any and all disputes that may be
filed in any court and that relate to the subject matter of this Plan or any of the transactions contemplated hereby, including, ERISA
claims, contract claims, tort claims and all other common law and statutory claims. This waiver and covenant is irrevocable and
shall apply to any subsequent amendments, supplements or other modifications to this Agreement.

Section 8.6    No Assignment. Executives will not have any right to pledge, hypothecate, anticipate or assign benefits or

and  be  enforceable  by  a  Participant,  his  or  her  Personal  or  legal  representatives,  executors,  administrators,  successors,  heirs,
distributees, devisees and legatees. If a Participant should die before severance benefit payments hereunder have been paid in full,
the remaining severance pay benefit payments shall be paid in accordance with the terms of this Plan to his or her surviving spouse,
or if there is no surviving spouse to the Participant’s surviving children or, if there are no surviving children, to the Participant’s
estate. The provisions of this Plan, including the Participant covenants herein, shall inure to the benefit of and be enforceable by the
Company and its Affiliates, successors and assigns.

Section 8.7    Severability. If  any  provision  of  the  Plan  is  held  invalid  or  unenforceable,  its  validity  or  unenforceability
shall not affect any other provisions of the Plan, and the Plan shall be construed and enforced as if such provision had not been
included herein.

Section  8.8        Information  Requested.  Participants  or  other  Persons  entitled  to  benefits  hereunder  shall  provide  the
Company, the Employer, the Administrator, and their authorized representatives with such information and evidence, and shall sign
such documents, as may reasonably be requested from time to time for the purpose of administration of the Plan.

Section 8.9    Basis of Payments to and From Plan. The benefits provided herein will be unfunded and will be provided
from the Employers’ general assets. No Participant will have any right to, or interest in, any assets of any Employer that may be
applied by the Employer to the payment of amounts due hereunder.

ARTICLE 2 
STATEMENT OF ERISA RIGHTS

Participants  in  this  Plan  (which  is  both  a  welfare  benefit  plan  and  a  pension  benefit  plan  sponsored  by  Diamondback
Energy, Inc.) are entitled to certain rights and protections under ERISA. If you are designated as an Eligible Senior Executive by
the Administrator, selected by the Administrator to participate in the Plan and have entered into a Participation Agreement with the
Company, you are considered a Participant in the Plan and, under ERISA, you are entitled to:

Receive Information about Your Plan and Benefits

(a) Examine,  without  charge,  at  the  Plan  Administrator’s  office  and  at  other  specified  locations,  such  as  worksites,  all
documents governing the Plan and a copy of the latest annual report (Form 5500 Series) filed by the Plan with the U.S.
Department of Labor and available at the Public Disclosure Room of the Employee Benefits Security Administration;

(b) Obtain, upon written request to the Plan Administrator, copies of documents governing the operation of the Plan and
copies of the latest annual report (Form 5500 Series) and updated Summary Plan Description. The Administrator may
make a reasonable charge for the copies; and

(c) Receive  a  summary  of  the  Plan’s  annual  financial  report.  The  Plan  Administrator  is  required  by  law  to  furnish  each

participant with a copy of this summary annual report.

Prudent Actions by Plan Fiduciaries

In  addition  to  creating  rights  for  Plan  participants,  ERISA  imposes  duties  upon  the  people  who  are  responsible  for  the
operation  of  the  employee  benefit  plan.  The  people  who  operate  the  Plan,  called  “fiduciaries”  of  the  Plan,  have  a  duty  to  do  so
prudently and in the interest of you and other Plan participants and beneficiaries. No one, including your employer, your union or
any other Person, may fire you or otherwise discriminate against you in any way to prevent you from obtaining a Plan benefit or
exercising your rights under ERISA.

Enforce Your Rights

If your claim for a Plan benefit is denied or ignored, in whole or in part, you have a right to know why this was done, to

obtain copies of documents relating to the decision without charge, and to appeal any denial, all within certain time schedules.

Under  ERISA,  there  are  steps  you  can  take  to  enforce  the  above  rights.  For  instance,  if  you  request  a  copy  of  Plan
documents or the latest annual report from the Plan and do not receive them within 30 days, you may file suit in a Federal court. In
such a case, the court may require the Plan Administrator to provide the materials and pay you up to $110 a day until you receive
the materials, unless the materials were not sent because of reasons beyond the control of the Administrator.

If you have a claim for benefits, which is denied or ignored, in whole or in part, you may file suit in a state or Federal court.
In addition, if you disagree with the Plan’s decision or lack thereof concerning the qualified status of a domestic relations order or a
medical child support order, you may file suit in Federal court.

2

If  it  should  happen  that  Plan  fiduciaries  misuse  the  Plan’s  money,  or  if  you  are  discriminated  against  for  asserting  your
rights, you may seek assistance from the U.S. Department of Labor, or you may file suit in a Federal court. The court will decide
who should pay court costs and legal fees. If you are successful, the court may order the Person you have sued to pay these costs
and fees. If you lose, the court may order you to pay these costs and fees, for example, if it finds your claim is frivolous.

Assistance with Your Questions

If you have any questions about the Plan, you should contact the Plan Administrator. If you have any questions about this
statement or about your rights under ERISA, or if you need assistance in obtaining documents from the Plan Administrator, you
should  contact  the  nearest  office  of  the  Employee  Benefits  Security  Administration,  U.S.  Department  of  Labor,  listed  in  your
telephone  directory  or  the  Division  of  Technical  Assistance  and  Inquiries,  Employee  Benefits  Security  Administration,  U.S.
Department  of  Labor,  200  Constitution  Avenue  N.W.,  Washington,  D.C.  20210.  You  may  also  obtain  certain  publications  about
your rights and responsibilities under ERISA by calling the publications hotline of the Employee Benefits Security Administration.

The  multiple  of  base  salary  and  the  number  of  months  that  the  multiple  of  base  salary  will  continue  to  be  paid  upon  a

Qualifying Termination outside of the Protection Period is determined based on the position of the Executive as follows:

Ladies and Gentlemen:

January 10, 2020

At  your  request,  Ryder  Scott  Company,  L.P.  (Ryder  Scott)  has  prepared  an  estimate  of  the  proved  reserves,  future
production, and income attributable to certain leasehold and royalty interests of Diamondback Energy, Inc. (Diamondback) as of
December 31, 2019. The subject properties are located in the states of New Mexico and Texas. The reserves and income data
were  estimated  based  on  the  definitions  and  disclosure  guidelines  of  the  United  States  Securities  and  Exchange  Commission
(SEC) contained in Title 17, Code of Federal Regulations, Modernization of Oil and Gas Reporting, Final Rule released January
14, 2009 in the Federal Register (SEC regulations). Our third party study, completed on January 7, 2020 and presented herein,
was prepared for public disclosure by Diamondback in filings made with the SEC in accordance with the disclosure requirements
set forth in the SEC regulations.

The properties evaluated by Ryder Scott represent 100 percent of the total net proved liquid hydrocarbon reserves and 100

percent of the total net proved gas reserves of Diamondback as of December 31, 2019.

The estimated reserves and future net income amounts presented in this report, as of December 31, 2019 are related to
hydrocarbon prices. The hydrocarbon prices used in the preparation of this report are based on the average prices during the 12-
month period prior to the “as of date” of this report, determined as the unweighted arithmetic averages of the prices in effect on the
first-day-of-the-month for each month within such period, unless prices were defined by contractual arrangements, as required by
the  SEC  regulations.  Actual  future  prices  may  vary  considerably  from  the  prices  required  by  SEC  regulations.  The  recoverable
reserves  volumes  and  the  income  attributable  thereto  have  a  direct  relationship  to  the  hydrocarbon  prices  actually  received;
therefore, volumes of reserves actually recovered and the amounts of income actually received may differ significantly from the
estimated quantities presented in this report. The results of this study are summarized as follows.

Liquid hydrocarbons are expressed in standard 42 U.S. gallon barrels and shown herein as thousands of barrels (Mbbl). All
gas volumes are reported on an “as sold basis” expressed in millions of cubic feet (MMcf) at the official temperature and pressure
bases  of  the  areas  in  which  the  gas  reserves  are  located.  The  net  reserves  are  also  shown  herein  on  an  equivalent  unit  basis
wherein natural gas is converted to oil equivalent using a factor of 6,000 cubic feet of natural gas per one barrel of oil equivalent.
MBOE  means  thousand  barrels  of  oil  equivalent.  In  this  report,  the  revenues,  deductions,  and  income  data  are  expressed  as
thousands of U.S. dollars ($M).

The estimates of the reserves, future production, and income attributable to properties in this report were prepared using
the  economic  software  package ARIESTM  Petroleum  Economics  and  Reserves  Software,  a  copyrighted  program  of  Halliburton.
The program was used at the request of Diamondback. Ryder Scott has found this program to be generally acceptable, but notes
that  certain  summaries  and  calculations  may  vary  due  to  rounding  and  may  not  exactly  match  the  sum  of  the  properties  being
summarized. Furthermore,  one  line  economic  summaries  may  vary  slightly  from  the  more  detailed  cash  flow  projections  of  the
same properties, also due to rounding. The rounding differences are not material.

The future gross revenue is after the deduction of production taxes. The deductions incorporate the normal direct costs of
operating  the  wells,  ad  valorem  taxes,  recompletion  costs,  development  costs,  and  certain  abandonment  costs  net  of  salvage.
“Other”  costs  shown  in  the  cash  flow  are  variable  production  costs.  The  future  net  income  is  before  the  deduction  of  state  and
federal  income  taxes  and  general  administrative  overhead,  and  has  not  been  adjusted  for  outstanding  loans  that  may  exist  nor
does it include any adjustment for cash on hand or undistributed income.

Reserves Included in This Report

The proved reserves included herein conform to the definition as set forth in the Securities and Exchange Commission’s
Regulations  Part  210.4-10(a).  An  abridged  version  of  the  SEC  reserves  definitions  from  210.4-10(a)  entitled  “PETROLEUM
RESERVES DEFINITIONS” is included as an attachment to this report.

The  various  reserves  status  categories  are  defined  in  the  attachment  entitled  “PETROLEUM  RESERVES  STATUS

DEFINITIONS AND GUIDELINES” in this report.

No attempt was made to quantify or otherwise account for any accumulated gas production imbalances that may exist. The

proved gas volumes presented herein do not include volumes of gas consumed in operations as reserves.

Reserves  are  “estimated  remaining  quantities  of  oil  and  gas  and  related  substances  anticipated  to  be  economically
producible, as of a given date, by application of development projects to known accumulations.” All reserves estimates involve an
assessment of the uncertainty relating the likelihood that the actual remaining quantities recovered will be greater or less than the
estimated quantities determined as of the date the estimate is made. The uncertainty depends chiefly on the amount of reliable
geologic  and  engineering  data  available  at  the  time  of  the  estimate  and  the  interpretation  of  these  data.  The relative degree of
uncertainty may be conveyed by placing reserves into one of two principal classifications, either proved or unproved. Unproved
reserves  are  less  certain  to  be  recovered  than  proved  reserves  and  may  be  further  sub-categorized  as  probable  and  possible
reserves  to  denote  progressively  increasing  uncertainty  in  their  recoverability.  At  Diamondback’s  request,  this  report  addresses
only the proved reserves attributable to the properties evaluated herein.

Proved oil and gas reserves are “those quantities of oil and gas which, by analysis of geoscience and engineering data,

can be estimated with reasonable certainty to be economically producible from a

RYDER SCOTT COMPANY PETROLEUM CONSULTANTS

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Diamondback Energy, Inc. (FANG)

given  date  forward.”  The  proved  reserves  included  herein  were  estimated  using  deterministic  methods.  The  SEC  has  defined
reasonable  certainty  for  proved  reserves,  when  based  on  deterministic  methods,  as  a  “high  degree  of  confidence  that  the
quantities will be recovered.”

Proved reserves estimates will generally be revised only as additional geologic or engineering data become available or as
economic conditions change. For proved reserves, the SEC states that “as changes due to increased availability of geoscience
(geological, geophysical, and geochemical), engineering, and economic data are made to the estimated ultimate recovery (EUR)
with time, reasonably certain EUR is much more likely to increase or remain constant than to decrease.” Moreover, estimates of
proved reserves may be revised as a result of future operations, effects of regulation by governmental agencies or geopolitical or
economic risks. Therefore, the proved reserves included in this report are estimates only and should not be construed as being
exact quantities, and if recovered, the revenues therefrom, and the actual costs related thereto, could be more or less than the
estimated amounts.

Diamondback’s operations may be subject to various levels of governmental controls and regulations. These controls and
regulations  may  include,  but  may  not  be  limited  to,  matters  relating  to  land  tenure  and  leasing,  the  legal  rights  to  produce
hydrocarbons, drilling and production practices, environmental protection, marketing and pricing policies, royalties, various taxes
and  levies  including  income  tax  and  are  subject  to  change  from  time  to  time.  Such  changes  in  governmental  regulations  and
policies  may  cause  volumes  of  proved  reserves  actually  recovered  and  amounts  of  proved  income  actually  received  to  differ
significantly from the estimated quantities.

The  estimates  of  proved  reserves  presented  herein  were  based  upon  a  detailed  study  of  the  properties  in  which
Diamondback owns an interest; however, we have not made any field examination of the properties. No consideration was given
in this report to potential environmental liabilities that may exist nor were any costs included for potential liabilities to restore and
clean up damages, if any, caused by past operating practices.

Estimates of Reserves

The  estimation  of  reserves  involves  two  distinct  determinations.  The  first  determination  results  in  the  estimation  of  the
quantities  of  recoverable  oil  and  gas  and  the  second  determination  results  in  the  estimation  of  the  uncertainty  associated  with
those estimated quantities in accordance with the definitions set forth by the Securities and Exchange Commission’s Regulations
Part  210.4-10(a).  The  process  of  estimating  the  quantities  of  recoverable  oil  and  gas  reserves  relies  on  the  use  of  certain
generally  accepted  analytical  procedures.  These  analytical  procedures  fall  into  three  broad  categories  or  methods:  (1)
performance-based  methods,  (2)  volumetric-based  methods  and  (3)  analogy.  These  methods  may  be  used  individually  or  in
combination by the reserves evaluator in the process of estimating the quantities of reserves. Reserves evaluators must select the
method  or  combination  of  methods  which  in  their  professional  judgment  is  most  appropriate  given  the  nature  and  amount  of
reliable  geoscience  and  engineering  data  available  at  the  time  of  the  estimate,  the  established  or  anticipated  performance
characteristics of the reservoir being evaluated, and the stage of development or producing maturity of the property.

In  many  cases,  the  analysis  of  the  available  geoscience  and  engineering  data  and  the  subsequent  interpretation  of  this
data  may  indicate  a  range  of  possible  outcomes  in  an  estimate,  irrespective  of  the  method  selected  by  the  evaluator.  When  a
range  in  the  quantity  of  reserves  is  identified,  the  evaluator  must  determine  the  uncertainty  associated  with  the  incremental
quantities of the reserves. If the reserves quantities are estimated using the deterministic incremental approach, the uncertainty for
each discrete incremental quantity of the reserves is addressed by the reserves category assigned by the evaluator.

RYDER SCOTT COMPANY PETROLEUM CONSULTANTS

Diamondback Energy, Inc. (FANG)
January 10, 2020
Page 5

Therefore,  it  is  the  categorization  of  reserves  quantities  as  proved,  probable  and/or  possible  that  addresses  the  inherent
uncertainty in the estimated quantities reported. For proved reserves, uncertainty is defined by the SEC as reasonable certainty
wherein the “quantities actually recovered are much more likely to be achieved than not.” The SEC states that “probable reserves
are those additional reserves that are less certain to be recovered than proved reserves but which, together with proved reserves,
are as likely as not to be recovered.” The SEC states that “possible reserves are those additional reserves that are less certain to
be  recovered  than  probable  reserves  and  the  total  quantities  ultimately  recovered  from  a  project  have  a  low  probability  of
exceeding proved plus probable plus possible reserves.” All quantities of reserves within the same reserves category must meet
the SEC definitions as noted above.

Estimates  of  reserves  quantities  and  their  associated  reserves  categories  may  be  revised  in  the  future  as  additional
geoscience  or  engineering  data  become  available.  Furthermore,  estimates  of  reserves  quantities  and  their  associated  reserves
categories may also be revised due to other factors such as changes in economic conditions, results of future operations, effects
of regulation by governmental agencies or geopolitical or economic risks as previously noted herein.

The  proved  reserves  for  the  properties  included  herein  were  estimated  by  performance  methods,  analogy,  or  a
combination  of  methods.  Approximately  80  percent  of  the  proved  producing  reserves  attributable  to  producing  wells  and/or
reservoirs were estimated by performance methods or a combination of methods. These performance methods include, but may
not be limited to, decline curve analysis which utilized extrapolations of historical production and pressure data available through
December, 2019 in those cases where such data were considered to be definitive. The data utilized in this analysis were furnished
to Ryder Scott by Diamondback or obtained from public data sources and were considered sufficient for the purpose thereof. The
remaining 20 percent of the proved producing reserves were estimated by analogy, or a combination of methods. These methods
were  used  where  there  were  inadequate  historical  performance  data  to  establish  a  definitive  trend  and  where  the  use  of
production performance data as a basis for the reserves estimates was considered to be inappropriate.

All proved undeveloped reserves included herein were estimated by the analogy method.

To  estimate  economically  recoverable  proved  oil  and  gas  reserves  and  related  future  net  cash  flows,  we  consider  many
factors  and  assumptions  including,  but  not  limited  to,  the  use  of  reservoir  parameters  derived  from  geological,  geophysical  and
engineering data which cannot be measured directly, economic criteria based on current costs and SEC pricing requirements, and
forecasts of future production rates. Under the SEC regulations 210.4-10(a)(22)(v) and (26), proved reserves must be anticipated
to be economically producible from a given date forward based on existing economic conditions including the prices and costs at
which economic producibility from a reservoir is to be determined. While it may reasonably be anticipated that the future prices
received for the sale of production and the operating costs and other costs relating to such production may increase or decrease
from those under existing economic conditions, such changes were, in accordance with rules adopted by the SEC, omitted from
consideration in making this evaluation.

Diamondback has informed us that they have furnished us all of the material accounts, records, geological and engineering
data, and reports and other data required for this investigation. In preparing our forecast of future proved production and income,
we  have  relied  upon  data  furnished  by  Diamondback  with  respect  to  property  interests  owned,  production  and  well  tests  from
examined wells, normal direct costs of operating the wells or leases, other costs such as transportation and/or processing fees, ad
valorem  and  production  taxes,  recompletion  and  development  costs,  development  plans,  abandonment  costs  after  salvage,
product  prices  based  on  the  SEC  regulations,  adjustments  or  differentials  to  product  prices,  geological  structural  and  isochore
maps, well logs, and pressure measurements. Ryder Scott reviewed such factual data for its reasonableness; however, we have
not conducted an independent

RYDER SCOTT COMPANY PETROLEUM CONSULTANTS

Diamondback Energy, Inc. (FANG)

Page 6

verification of the data furnished by Diamondback. We consider the factual data used in this report appropriate and sufficient for
the purpose of preparing the estimates of reserves and future net revenues herein.

In summary, we consider the assumptions, data, methods and analytical procedures used in this report appropriate for the
purpose hereof, and we have used all such methods and procedures that we consider necessary and appropriate to prepare the
estimates  of  reserves  herein.  The  proved  reserves  included  herein  were  determined  in  conformance  with  the  United  States
Securities  and  Exchange  Commission  (SEC)  Modernization  of  Oil  and  Gas  Reporting;  Final  Rule,  including  all  references  to
Regulation S-X and Regulation S-K, referred to herein collectively as the “SEC Regulations.” In our opinion, the proved reserves
presented in this report comply with the definitions, guidelines and disclosure requirements as required by the SEC regulations.

Future Production Rates

For wells currently on production, our forecasts of future production rates are based on historical performance data. If no
production decline trend has been established, future production rates were based on analog well performance and type-curves
where  appropriate,  until  a  decline  in  ability  to  produce  was  anticipated.  An  estimated  rate  of  decline  was  then  applied  until
depletion of the reserves. If a decline trend has been established, this trend was used as the basis for estimating future production
rates.

Test data and other related information were used to estimate the anticipated initial production rates for those locations that
are  not  currently  producing.  For  reserves  not  yet  on  production,  sales  were  estimated  to  commence  at  an  anticipated  date
furnished by Diamondback. Locations that are not currently producing may start producing earlier or later than anticipated in our
estimates due to unforeseen factors causing a change in the timing to initiate production. Such factors may include delays due to
weather, the availability of rigs, the sequence of drilling, completing and/or recompleting wells and/or constraints set by regulatory
bodies.

The future production rates from wells currently on production or locations that are not currently producing may be more or
less  than  estimated  because  of  changes  including,  but  not  limited  to,  reservoir  performance,  operating  conditions  related  to
surface  facilities,  compression  and  artificial  lift,  pipeline  capacity  and/or  operating  conditions,  producing  market  demand  and/or
allowables or other constraints set by regulatory bodies.

Hydrocarbon Prices

The  hydrocarbon  prices  used  herein  are  based  on  SEC  price  parameters  using  the  average  prices  during  the  12-month
period prior to the “as of date” of this report, determined as the unweighted arithmetic averages of the prices in effect on the first-
day-of-the-month  for  each  month  within  such  period,  unless  prices  were  defined  by  contractual  arrangements.  For  hydrocarbon
products sold under contract, the contract prices, including fixed and determinable escalations, exclusive of inflation adjustments,
were  used  until  expiration  of  the  contract.  Upon  contract  expiration,  the  prices  were  adjusted  to  the  12-month  unweighted
arithmetic average as previously described.

Diamondback furnished us with the above mentioned average prices in effect on December 31, 2019. These  initial  SEC
hydrocarbon  prices  were  determined  using  the  12-month  average  first-day-of-the-month  benchmark  prices  appropriate  to  the
geographic  area  where  the  hydrocarbons  are  sold.  These  benchmark  prices  are  prior  to  the  adjustments  for  differentials  as
described herein. The table below

RYDER SCOTT COMPANY PETROLEUM CONSULTANTS

summarizes  the  “benchmark  prices”  and  “price  reference”  used  for  the  geographic  area  included  in  the  report.  In  certain
geographic areas, the price reference and benchmark prices may be defined by contractual arrangements.

The product prices which were actually used to determine the future gross revenue for each property reflect adjustments to
the  benchmark  prices  for  gravity,  quality,  local  conditions,  and/or  distance  from  market,  referred  to  herein  as  “differentials.”  The
differentials  used  in  the  preparation  of  this  report  were  furnished  to  us  by  Diamondback.  The  differentials  furnished  to  us  were
accepted  as  factual  data  and  reviewed  by  us  for  their  reasonableness;  however,  we  have  not  conducted  an  independent
verification of the data used by Diamondback to determine these differentials.

In addition, the table below summarizes the net volume weighted benchmark prices adjusted for differentials and referred
to herein as the “average realized prices.” The average realized prices shown in the table below were determined from the total
future gross revenue before production taxes and the total net reserves for the geographic area and presented in accordance with
SEC disclosure requirements for the geographic areas included in the report.

Costs

Operating  costs  for  the  leases  and  wells  in  this  report  were  furnished  by  Diamondback  and  are  based  on  the  operating
expense  reports  of  Diamondback  and  include  only  those  costs  directly  applicable  to  the  leases  or  wells.  The  operating  costs
include  a  portion  of  general  and  administrative  costs  allocated  directly  to  the  leases  and  wells.  For  operated  properties,  the
operating costs include an appropriate level of corporate general administrative and overhead costs. The operating costs for non-
operated properties include the COPAS overhead costs that are allocated directly to the leases and wells under terms of operating
agreements.  The  operating  costs  furnished  to  us  were  accepted  as  factual  data  and  reviewed  by  us  for  their  reasonableness;
however, we have not conducted an independent verification of the operating cost data used by Diamondback. No deduction was
made for loan repayments, interest expenses, or exploration and development prepayments that were not charged directly to the
leases or wells.

Development  costs  were  furnished  to  us  by  Diamondback  and  are  based  on  authorizations  for  expenditure  for  the
proposed  work  or  actual  costs  for  similar  projects.  The  development  costs  furnished  to  us  were  accepted  as  factual  data  and

was included for properties where abandonment costs net of salvage were material. The estimates of the net abandonment costs
furnished by Diamondback were accepted without independent verification.

The proved undeveloped reserves in this report have been incorporated herein in accordance with Diamondback’s plans to
develop these reserves as of December 31, 2019. The implementation of Diamondback’s development plans as presented to us
and incorporated herein is subject to the approval process adopted by Diamondback’s management. As the result of our inquiries
during  the  course  of  preparing  this  report,  Diamondback  has  informed  us  that  the  development  activities  included  herein  have
been subjected to and received the internal approvals required by Diamondback’s management at the appropriate local, regional
and/or corporate level. In addition to the internal approvals as noted, certain development activities may still be subject to specific
partner  AFE  processes,  Joint  Operating  Agreement  (JOA)  requirements  or  other  administrative  approvals  external  to
Diamondback. Diamondback has provided written documentation supporting their commitment to proceed with the development
activities  as  presented  to  us.  Additionally,  Diamondback  has  informed  us  that  they  are  not  aware  of  any  legal,  regulatory,  or
political obstacles that would significantly alter their plans. While these plans could change from those under existing economic
conditions  as  of  December  31,  2019,  such  changes  were,  in  accordance  with  rules  adopted  by  the  SEC,  omitted  from
consideration in making this evaluation.

Current costs used by Diamondback were held constant throughout the life of the properties.

PETROLEUM RESERVES DEFINITIONS

As Adapted From:
RULE 4-10(a) of REGULATION S-X PART 210
UNITED STATES SECURITIES AND EXCHANGE COMMISSION (SEC)

PREAMBLE

On January 14, 2009, the United States Securities and Exchange Commission (SEC) published the “Modernization of Oil
and  Gas  Reporting;  Final  Rule”  in  the  Federal  Register  of  National  Archives  and  Records  Administration  (NARA).  The
“Modernization  of  Oil  and  Gas  Reporting;  Final  Rule”  includes  revisions  and  additions  to  the  definition  section  in  Rule  4-10  of
Regulation  S-X,  revisions  and  additions  to  the  oil  and  gas  reporting  requirements  in  Regulation  S-K,  and  amends  and  codifies
Industry  Guide  2  in  Regulation  S-K.  The  “Modernization  of  Oil  and  Gas  Reporting;  Final  Rule”,  including  all  references  to
Regulation S-X and Regulation S-K, shall be referred to herein collectively as the “SEC regulations”. The  SEC  regulations  take
effect for all filings made with the United States Securities and Exchange Commission as of December 31, 2009, or after January
1, 2010. Reference should be made to the full text under Title 17, Code of Federal Regulations, Regulation S-X Part 210, Rule 4-
10(a)  for  the  complete  definitions  (direct  passages  excerpted  in  part  or  wholly  from  the  aforementioned  SEC  document  are
denoted in italics herein).

Reserves  are  estimated  remaining  quantities  of  oil  and  gas  and  related  substances  anticipated  to  be  economically
producible, as of a given date, by application of development projects to known accumulations. All reserve estimates involve an
assessment of the uncertainty relating the likelihood that the actual remaining quantities recovered will be greater or less than the
estimated quantities determined as of the date the estimate is made. The uncertainty depends chiefly on the amount of reliable
geologic  and  engineering  data  available  at  the  time  of  the  estimate  and  the  interpretation  of  these  data.  The relative degree of
uncertainty may be conveyed by placing reserves into one of two principal classifications, either proved or unproved. Unproved
reserves  are  less  certain  to  be  recovered  than  proved  reserves  and  may  be  further  sub-classified  as  probable  and  possible
reserves  to  denote  progressively  increasing  uncertainty  in  their  recoverability.  Under  the  SEC  regulations  as  of  December  31,
2009,  or  after  January  1,  2010,  a  company  may  optionally  disclose  estimated  quantities  of  probable  or  possible  oil  and  gas
reserves in documents publicly filed with the SEC. The SEC regulations continue to prohibit disclosure of estimates of oil and gas
resources  other  than  reserves  and  any  estimated  values  of  such  resources  in  any  document  publicly  filed  with  the  SEC  unless
such  information  is  required  to  be  disclosed  in  the  document  by  foreign  or  state  law  as  noted  in  §229.1202  Instruction  to  Item
1202.

Reserves  estimates  will  generally  be  revised  only  as  additional  geologic  or  engineering  data  become  available  or  as

economic conditions change.

Reserves may be attributed to either natural energy or improved recovery methods. Improved recovery methods include all
methods  for  supplementing  natural  energy  or  altering  natural  forces  in  the  reservoir  to  increase  ultimate  recovery.  Examples  of
such methods are pressure maintenance, natural gas cycling, waterflooding, thermal methods, chemical flooding, and the use of
miscible  and  immiscible  displacement  fluids.  Other  improved  recovery  methods  may  be  developed  in  the  future  as  petroleum
technology continues to evolve.

RYDER SCOTT COMPANY PETROLEUM CONSULTANTS

PETROLEUM RESERVES DEFINITIONS
Page 2

Reserves may be attributed to either conventional or unconventional petroleum accumulations. Petroleum accumulations
are considered as either conventional or unconventional based on the nature of their in-place characteristics, extraction method
applied, or degree of processing prior to sale. Examples of unconventional petroleum accumulations include coalbed or coalseam
methane (CBM/CSM), basin-centered gas, shale gas, gas hydrates, natural bitumen and oil shale deposits. These unconventional
accumulations may require specialized extraction technology and/or significant processing prior to sale.

Reserves do not include quantities of petroleum being held in inventory.

Because  of  the  differences  in  uncertainty,  caution  should  be  exercised  when  aggregating  quantities  of  petroleum  from

different reserves categories.

RESERVES (SEC DEFINITIONS)

Securities and Exchange Commission Regulation S-X §210.4-10(a)(26) defines reserves as follows:

Reserves.  Reserves  are  estimated  remaining  quantities  of  oil  and  gas  and  related  substances  anticipated  to  be  economically
producible, as of a given date, by application of development projects to known accumulations. In  addition,  there  must  exist,  or
there  must  be  a  reasonable  expectation  that  there  will  exist,  the  legal  right  to  produce  or  a  revenue  interest  in  the  production,
installed means of delivering oil and gas or related substances to market, and all permits and financing required to implement the
project.

Note to paragraph (a)(26):  Reserves  should  not  be  assigned  to  adjacent  reservoirs  isolated  by  major,  potentially  sealing,  faults
until those reservoirs are penetrated and evaluated as economically producible. Reserves should not be assigned to areas that
are  clearly  separated  from  a  known  accumulation  by  a  non-productive  reservoir  (i.e.,  absence  of  reservoir,  structurally  low
reservoir,  or  negative  test  results).  Such  areas  may  contain  prospective  resources  (i.e.,  potentially  recoverable  resources  from
undiscovered accumulations).

PROVED RESERVES (SEC DEFINITIONS)

Securities and Exchange Commission Regulation S-X §210.4-10(a)(22) defines proved oil and gas reserves as follows:

Proved oil and gas reserves. Proved oil and gas reserves are those quantities of oil and gas, which, by analysis of geoscience
and engineering data, can be estimated with reasonable certainty to be economically producible—from a given date forward, from
known reservoirs, and under existing economic conditions, operating methods, and government regulations—prior to the time at
which contracts providing the right to operate expire, unless evidence indicates that renewal is reasonably certain, regardless of
whether  deterministic  or  probabilistic  methods  are  used  for  the  estimation.  The  project  to  extract  the  hydrocarbons  must  have
commenced or the operator must be reasonably certain that it will commence the project within a reasonable time.

(i) The area of the reservoir considered as proved includes:

(A) The area identified by drilling and limited by fluid contacts, if any, and

RYDER SCOTT COMPANY PETROLEUM CONSULTANTS

PETROLEUM RESERVES DEFINITIONS
Page 3

(B) Adjacent undrilled portions of the reservoir that can, with reasonable certainty, be judged to be continuous with
it and to contain economically producible oil or gas on the basis of available geoscience and engineering data.

(ii) In the absence of data on fluid contacts, proved quantities in a reservoir are limited by the lowest known hydrocarbons
(LKH)  as  seen  in  a  well  penetration  unless  geoscience,  engineering,  or  performance  data  and  reliable  technology
establishes a lower contact with reasonable certainty.

(iii)  Where  direct  observation  from  well  penetrations  has  defined  a  highest  known  oil  (HKO)  elevation  and  the  potential
exists for an associated gas cap, proved oil reserves may be assigned in the structurally higher portions of the reservoir
only if geoscience, engineering, or performance data and reliable technology establish the higher contact with reasonable
certainty.

(iv) Reserves which can be produced economically through application of improved recovery techniques (including, but not
limited to, fluid injection) are included in the proved classification when:

(A)  Successful  testing  by  a  pilot  project  in  an  area  of  the  reservoir  with  properties  no  more  favorable  than  in  the
reservoir  as  a  whole,  the  operation  of  an  installed  program  in  the  reservoir  or  an  analogous  reservoir,  or  other
evidence  using  reliable  technology  establishes  the  reasonable  certainty  of  the  engineering  analysis  on  which  the
project or program was based; and

(B) The project has been approved for development by all necessary parties and entities, including governmental
entities.

(v)  Existing  economic  conditions  include  prices  and  costs  at  which  economic  producibility  from  a  reservoir  is  to  be
determined. The price shall be the average price during the 12-month period prior to the ending date of the period covered
by  the  report,  determined  as  an  unweighted  arithmetic  average  of  the  first-day-of-the-month  price  for  each  month  within
such period, unless prices are defined by contractual arrangements, excluding escalations based upon future conditions.

Reserves  status  categories  define  the  development  and  producing  status  of  wells  and  reservoirs.  Reference  should  be
made  to  Title  17,  Code  of  Federal  Regulations,  Regulation  S-X  Part  210,  Rule  4-10(a)  and  the  SPE-PRMS  as  the  following
reserves  status  definitions  are  based  on  excerpts  from  the  original  documents  (direct  passages  excerpted  from  the
aforementioned SEC and SPE-PRMS documents are denoted in italics herein).

DEVELOPED RESERVES (SEC DEFINITIONS)

Securities and Exchange Commission Regulation S-X §210.4-10(a)(6) defines developed oil and gas reserves as follows:

Developed oil and gas reserves are reserves of any category that can be expected to be recovered:

(i)  Through  existing  wells  with  existing  equipment  and  operating  methods  or  in  which  the  cost  of  the  required
equipment is relatively minor compared to the cost of a new well; and

(ii) Through installed extraction equipment and infrastructure operational at the time of the reserves estimate if the
extraction is by means not involving a well.

Developed Producing (SPE-PRMS Definitions)

While  not  a  requirement  for  disclosure  under  the  SEC  regulations,  developed  oil  and  gas  reserves  may  be  further  sub-

classified according to the guidance contained in the SPE-PRMS as Producing or Non-Producing.

RYDER SCOTT COMPANY PETROLEUM CONSULTANTS

PETROLEUM RESERVES STATUS DEFINITIONS AND GUIDELINES
Page 2

Developed Producing Reserves
Developed  Producing  Reserves  are  expected  quantities  to  be  recovered  from  completion  intervals  that  are  open  and
producing at the effective date of the estimate.

Improved recovery reserves are considered producing only after the improved recovery project is in operation.

Developed Non-Producing
Developed Non-Producing Reserves include shut-in and behind-pipe Reserves.

Shut-In
Shut-in Reserves are expected to be recovered from:

(1)completion intervals that are open at the time of the estimate but which have not yet started producing;
(2)wells which were shut-in for market conditions or pipeline connections; or
(3)wells not capable of production for mechanical reasons.

Behind-Pipe
Behind-pipe  Reserves  are  expected  to  be  recovered  from  zones  in  existing  wells  that  will  require  additional  completion
work or future re-completion before start of production with minor cost to access these reserves.

In all cases, production can be initiated or restored with relatively low expenditure compared to the cost of drilling a new
well.

UNDEVELOPED RESERVES (SEC DEFINITIONS)

Securities  and  Exchange  Commission  Regulation  S-X  §210.4-10(a)(31)  defines  undeveloped  oil  and  gas  reserves  as

follows:

Undeveloped  oil  and  gas  reserves  are  reserves  of  any  category  that  are  expected  to  be  recovered  from  new  wells  on
undrilled acreage, or from existing wells where a relatively major expenditure is required for recompletion.

(i)Reserves on undrilled acreage shall be limited to those directly offsetting development spacing areas that are

reasonably certain of production when drilled, unless evidence using reliable technology exists that establishes
reasonable certainty of economic producibility at greater distances.

(ii)  Undrilled  locations  can  be  classified  as  having  undeveloped  reserves  only  if  a  development  plan  has  been
adopted indicating that they are scheduled to be drilled within five years, unless the specific circumstances, justify a
longer time.

(iii) Under no circumstances shall estimates for undeveloped reserves be attributable to any acreage for which an
application  of  fluid  injection  or  other  improved  recovery  technique  is  contemplated,  unless  such  techniques  have
been proved effective by actual projects in the same reservoir or an analogous reservoir, as defined in paragraph
(a)(2) of this section, or by other evidence using reliable technology establishing reasonable certainty.

Ladies and Gentlemen:

January 10, 2020

At  your  request,  Ryder  Scott  Company,  L.P.  (Ryder  Scott)  has  prepared  an  estimate  of  the  proved  reserves,  future
production, and income attributable to certain royalty interests of Viper Energy Partners, LP (Viper), a subsidiary of Diamondback
Energy, Inc. (Diamondback) as of December 31, 2019. The subject properties are located in the states of New Mexico and Texas.
The reserves and income data were estimated based on the definitions and disclosure guidelines of the United States Securities
and Exchange Commission (SEC) contained in Title 17, Code of Federal Regulations, Modernization of Oil and Gas Reporting,
Final Rule released January 14, 2009 in the Federal Register (SEC regulations). Our third party study, completed on January 7,
2020  and  presented  herein,  was  prepared  for  public  disclosure  by  Viper  in  filings  made  with  the  SEC  in  accordance  with  the
disclosure requirements set forth in the SEC regulations.

The properties evaluated by Ryder Scott represent 100 percent of the total net proved liquid hydrocarbon reserves and 100

percent of the total net proved gas reserves of Viper as of December 31, 2019.

The estimated reserves and future net income amounts presented in this report, as of December 31, 2019 are related to
hydrocarbon prices. The hydrocarbon prices used in the preparation of this report are based on the average prices during the 12-
month period prior to the “as of date” of this report, determined as the unweighted arithmetic averages of the prices in effect on the
first-day-of-the-month for each month within such period, unless prices were defined by contractual arrangements, as required by
the  SEC  regulations.  Actual  future  prices  may  vary  considerably  from  the  prices  required  by  SEC  regulations.  The  recoverable
reserves  volumes  and  the  income  attributable  thereto  have  a  direct  relationship  to  the  hydrocarbon  prices  actually  received;
therefore, volumes of reserves actually recovered and the amounts of income actually received may differ significantly from the
estimated quantities presented in this report. The results of this study are summarized as follows.

Liquid hydrocarbons are expressed in standard 42 U.S. gallon barrels and shown herein as thousands of barrels (Mbbl). All
gas volumes are reported on an “as sold basis” expressed in millions of cubic feet (MMcf) at the official temperature and pressure
bases  of  the  areas  in  which  the  gas  reserves  are  located.  The  net  reserves  are  also  shown  herein  on  an  equivalent  unit  basis
wherein natural gas is converted to oil equivalent using a factor of 6,000 cubic feet of natural gas per one barrel of oil equivalent.
MBOE  means  thousand  barrels  of  oil  equivalent.  In  this  report,  the  revenues,  deductions,  and  income  data  are  expressed  as
thousands of U.S. dollars ($M).

The estimates of the reserves, future production, and income attributable to properties in this report were prepared using
the  economic  software  package ARIESTM  Petroleum  Economics  and  Reserves  Software,  a  copyrighted  program  of  Halliburton.
The  program  was  used  at  the  request  of  Viper.  Ryder  Scott  has  found  this  program  to  be  generally  acceptable,  but  notes  that
certain  summaries  and  calculations  may  vary  due  to  rounding  and  may  not  exactly  match  the  sum  of  the  properties  being
summarized. Furthermore,  one  line  economic  summaries  may  vary  slightly  from  the  more  detailed  cash  flow  projections  of  the
same properties, also due to rounding. The rounding differences are not material.

The  future  gross  revenue  is  after  the  deduction  of  production  taxes.  Because  the  interests  evaluated  herein  are  royalty
interests, the deductions include only ad valorem taxes. The future net income is before the deduction of state and federal income
taxes and general administrative overhead, and has not been adjusted for outstanding loans that may exist nor does it include any
adjustment for cash on hand or undistributed income.

Liquid hydrocarbon reserves account for approximately 98 percent and gas reserves account for the remaining 2 percent

of total future gross revenue from proved reserves.

Reserves Included in This Report

The proved reserves included herein conform to the definition as set forth in the Securities and Exchange Commission’s
Regulations  Part  210.4-10(a).  An  abridged  version  of  the  SEC  reserves  definitions  from  210.4-10(a)  entitled  “PETROLEUM
RESERVES DEFINITIONS” is included as an attachment to this report.

The  various  reserves  status  categories  are  defined  in  the  attachment  entitled  “PETROLEUM  RESERVES  STATUS

DEFINITIONS AND GUIDELINES” in this report.

No attempt was made to quantify or otherwise account for any accumulated gas production imbalances that may exist. The

proved gas volumes presented herein do not include volumes of gas consumed in operations as reserves.

Reserves  are  “estimated  remaining  quantities  of  oil  and  gas  and  related  substances  anticipated  to  be  economically
producible, as of a given date, by application of development projects to known accumulations.” All reserves estimates involve an
assessment of the uncertainty relating the likelihood that the actual remaining quantities recovered will be greater or less than the
estimated quantities determined as of the date the estimate is made. The uncertainty depends chiefly on the amount of reliable
geologic  and  engineering  data  available  at  the  time  of  the  estimate  and  the  interpretation  of  these  data.  The relative degree of
uncertainty may be conveyed by placing reserves into one of two principal classifications, either proved or unproved. Unproved
reserves  are  less  certain  to  be  recovered  than  proved  reserves  and  may  be  further  sub-categorized  as  probable  and  possible
reserves  to  denote  progressively  increasing  uncertainty  in  their  recoverability.  At Viper’s request, this report addresses only the
proved reserves attributable to the properties evaluated herein.

Proved oil and gas reserves are “those quantities of oil and gas which, by analysis of geoscience and engineering data,
can  be  estimated  with  reasonable  certainty  to  be  economically  producible  from  a  given  date  forward.”  The  proved  reserves
included  herein  were  estimated  using  deterministic  methods.  The  SEC  has  defined  reasonable  certainty  for  proved  reserves,
when based on deterministic methods, as a “high degree of confidence that the quantities will be recovered.”

Proved reserves estimates will generally be revised only as additional geologic or engineering data become available or as
economic conditions change. For proved reserves, the SEC states that “as changes due to increased availability of geoscience
(geological, geophysical, and geochemical), engineering, and economic data are made to the estimated ultimate recovery (EUR)
with time, reasonably certain EUR is much more likely to increase or remain constant than to decrease.” Moreover, estimates of
proved reserves may be revised as a result of future operations, effects of regulation by governmental agencies or geopolitical or
economic risks. Therefore, the proved reserves included in this report are estimates only and should not be construed as being
exact quantities, and if recovered, the revenues therefrom, and the actual costs related thereto, could be more or less than the
estimated amounts.

Diamondback’s operations may be subject to various levels of governmental controls and regulations. These controls and
regulations  may  include,  but  may  not  be  limited  to,  matters  relating  to  land  tenure  and  leasing,  the  legal  rights  to  produce
hydrocarbons, drilling and production practices, environmental protection, marketing and pricing policies, royalties, various taxes
and  levies  including  income  tax  and  are  subject  to  change  from  time  to  time.  Such  changes  in  governmental  regulations  and
policies  may  cause  volumes  of  proved  reserves  actually  recovered  and  amounts  of  proved  income  actually  received  to  differ
significantly from the estimated quantities.

The  estimates  of  proved  reserves  presented  herein  were  based  upon  a  detailed  study  of  the  properties  in  which  Viper
owns an interest; however, we have not made any field examination of the properties. No consideration was given in this report to
potential  environmental  liabilities  that  may  exist  nor  were  any  costs  included  for  potential  liabilities  to  restore  and  clean  up
damages, if any, caused by past operating practices.

Estimates of Reserves

The  estimation  of  reserves  involves  two  distinct  determinations.  The  first  determination  results  in  the  estimation  of  the
quantities  of  recoverable  oil  and  gas  and  the  second  determination  results  in  the  estimation  of  the  uncertainty  associated  with
those estimated quantities in accordance with the definitions set forth by the Securities and Exchange Commission’s Regulations
Part  210.4-10(a).  The  process  of  estimating  the  quantities  of  recoverable  oil  and  gas  reserves  relies  on  the  use  of  certain
generally  accepted  analytical  procedures.  These  analytical  procedures  fall  into  three  broad  categories  or  methods:  (1)
performance-based  methods,  (2)  volumetric-based  methods  and  (3)  analogy.  These  methods  may  be  used  individually  or  in
combination by the reserves evaluator in the process of estimating the quantities of reserves. Reserves evaluators must select the
method  or  combination  of  methods  which  in  their  professional  judgment  is  most  appropriate  given  the  nature  and  amount  of
reliable  geoscience  and  engineering  data  available  at  the  time  of  the  estimate,  the  established  or  anticipated  performance
characteristics of the reservoir being evaluated, and the stage of development or producing maturity of the property.

In  many  cases,  the  analysis  of  the  available  geoscience  and  engineering  data  and  the  subsequent  interpretation  of  this
data  may  indicate  a  range  of  possible  outcomes  in  an  estimate,  irrespective  of  the  method  selected  by  the  evaluator.  When  a
range  in  the  quantity  of  reserves  is  identified,  the  evaluator  must  determine  the  uncertainty  associated  with  the  incremental
quantities of the reserves. If the reserves quantities are estimated using the deterministic incremental approach, the uncertainty for
each discrete incremental quantity of the reserves is addressed by the reserves category assigned by the evaluator. Therefore, it
is  the  categorization  of  reserves  quantities  as  proved,  probable  and/or  possible  that  addresses  the  inherent  uncertainty  in  the
estimated  quantities  reported.  For  proved  reserves,  uncertainty  is  defined  by  the  SEC  as  reasonable  certainty  wherein  the
“quantities actually recovered are much more likely to be achieved than not.” The SEC states that “probable reserves are those
additional reserves that are less certain to be recovered than proved reserves but which, together with proved reserves, are as
likely as not to be recovered.” The SEC states that “possible reserves are those additional reserves that are less certain to

RYDER SCOTT COMPANY PETROLEUM CONSULTANTS

Viper Energy Partners, LP
January 18, 2019
Page 5

be  recovered  than  probable  reserves  and  the  total  quantities  ultimately  recovered  from  a  project  have  a  low  probability  of
exceeding proved plus probable plus possible reserves.” All quantities of reserves within the same reserves category must meet
the SEC definitions as noted above.

Estimates  of  reserves  quantities  and  their  associated  reserves  categories  may  be  revised  in  the  future  as  additional
geoscience  or  engineering  data  become  available.  Furthermore,  estimates  of  reserves  quantities  and  their  associated  reserves
categories may also be revised due to other factors such as changes in economic conditions, results of future operations, effects
of regulation by governmental agencies or geopolitical or economic risks as previously noted herein.

The  proved  reserves  for  the  properties  included  herein  were  estimated  by  performance  methods,  analogy,  or  a
combination  of  methods.  Approximately  85  percent  of  the  proved  producing  reserves  attributable  to  producing  wells  and/or
reservoirs were estimated by performance methods or a combination of methods. These performance methods include, but may
not be limited to, decline curve analysis which utilized extrapolations of historical production and pressure data available through
December, 2019 in those cases where such data were considered to be definitive. The data utilized in this analysis were furnished
to Ryder Scott by Diamondback or obtained from public data sources and were considered sufficient for the purpose thereof. The
remaining 15 percent of the proved producing reserves were estimated by analogy, or a combination of methods. These methods
were  used  where  there  were  inadequate  historical  performance  data  to  establish  a  definitive  trend  and  where  the  use  of
production performance data as a basis for the reserves estimates was considered to be inappropriate.

All proved undeveloped reserves included herein were estimated by the analogy method.

To  estimate  economically  recoverable  proved  oil  and  gas  reserves  and  related  future  net  cash  flows,  we  consider  many
factors  and  assumptions  including,  but  not  limited  to,  the  use  of  reservoir  parameters  derived  from  geological,  geophysical  and
engineering data which cannot be measured directly, economic criteria based on current costs and SEC pricing requirements, and
forecasts of future production rates. Under the SEC regulations 210.4-10(a)(22)(v) and (26), proved reserves must be anticipated
to be economically producible from a given date forward based on existing economic conditions including the prices and costs at
which economic producibility from a reservoir is to be determined. While it may reasonably be anticipated that the future prices
received for the sale of production and the operating costs and other costs relating to such production may increase or decrease
from those under existing economic conditions, such changes were, in accordance with rules adopted by the SEC, omitted from
consideration in making this evaluation.

Diamondback has informed us that they have furnished us all of the material accounts, records, geological and engineering
data, and reports and other data required for this investigation. In preparing our forecast of future proved production and income,
we  have  relied  upon  data  furnished  by  Diamondback  with  respect  to  property  interests  owned,  production  and  well  tests  from
examined wells, normal direct costs of operating the wells or leases, other costs such as transportation and/or processing fees, ad
valorem  and  production  taxes,  recompletion  and  development  costs,  development  plans,  abandonment  costs  after  salvage,
product  prices  based  on  the  SEC  regulations,  adjustments  or  differentials  to  product  prices,  geological  structural  and  isochore
maps, well logs, and pressure measurements. Ryder Scott reviewed such factual data for its reasonableness; however, we have
not conducted an independent verification of the data furnished by Diamondback. We consider the factual data used in this report
appropriate and sufficient for the purpose of preparing the estimates of reserves and future net revenues herein.

In summary, we consider the assumptions, data, methods and analytical procedures used in this report appropriate for the
purpose hereof, and we have used all such methods and procedures that we consider necessary and appropriate to prepare the
estimates of reserves herein. The proved reserves

RYDER SCOTT COMPANY PETROLEUM CONSULTANTS

Viper Energy Partners, LP

Page 6

included  herein  were  determined  in  conformance  with  the  United  States  Securities  and  Exchange  Commission  (SEC)
Modernization  of  Oil  and  Gas  Reporting;  Final  Rule,  including  all  references  to  Regulation  S-X  and  Regulation  S-K,  referred  to
herein  collectively  as  the  “SEC  Regulations.”  In  our  opinion,  the  proved  reserves  presented  in  this  report  comply  with  the
definitions, guidelines and disclosure requirements as required by the SEC regulations.

Future Production Rates

For wells currently on production, our forecasts of future production rates are based on historical performance data. If no
production decline trend has been established, future production rates were based on analog well performance and type-curves
where  appropriate,  until  a  decline  in  ability  to  produce  was  anticipated.  An  estimated  rate  of  decline  was  then  applied  until
depletion of the reserves. If a decline trend has been established, this trend was used as the basis for estimating future production
rates.

Test data and other related information were used to estimate the anticipated initial production rates for those locations that
are  not  currently  producing.  For  reserves  not  yet  on  production,  sales  were  estimated  to  commence  at  an  anticipated  date
furnished by Diamondback. Locations that are not currently producing may start producing earlier or later than anticipated in our
estimates due to unforeseen factors causing a change in the timing to initiate production. Such factors may include delays due to
weather, the availability of rigs, the sequence of drilling, completing and/or recompleting wells and/or constraints set by regulatory
bodies.

The future production rates from wells currently on production or locations that are not currently producing may be more or
less  than  estimated  because  of  changes  including,  but  not  limited  to,  reservoir  performance,  operating  conditions  related  to
surface  facilities,  compression  and  artificial  lift,  pipeline  capacity  and/or  operating  conditions,  producing  market  demand  and/or
allowables or other constraints set by regulatory bodies.

Hydrocarbon Prices

The  hydrocarbon  prices  used  herein  are  based  on  SEC  price  parameters  using  the  average  prices  during  the  12-month
period prior to the “as of date” of this report, determined as the unweighted arithmetic averages of the prices in effect on the first-
day-of-the-month  for  each  month  within  such  period,  unless  prices  were  defined  by  contractual  arrangements.  For  hydrocarbon
products sold under contract, the contract prices, including fixed and determinable escalations, exclusive of inflation adjustments,
were  used  until  expiration  of  the  contract.  Upon  contract  expiration,  the  prices  were  adjusted  to  the  12-month  unweighted
arithmetic average as previously described.

Diamondback furnished us with the above mentioned average prices in effect on December 31, 2019. These  initial  SEC
hydrocarbon  prices  were  determined  using  the  12-month  average  first-day-of-the-month  benchmark  prices  appropriate  to  the
geographic  area  where  the  hydrocarbons  are  sold.  These  benchmark  prices  are  prior  to  the  adjustments  for  differentials  as
described  herein.  The  table  below  summarizes  the  “benchmark  prices”  and  “price  reference”  used  for  the  geographic  area
included  in  the  report.  In  certain  geographic  areas,  the  price  reference  and  benchmark  prices  may  be  defined  by  contractual
arrangements.

The product prices which were actually used to determine the future gross revenue for each property reflect adjustments to
the  benchmark  prices  for  gravity,  quality,  local  conditions,  and/or  distance  from  market,  referred  to  herein  as  “differentials.”  The
differentials  used  in  the  preparation  of  this  report  were  furnished  to  us  by  Diamondback.  The  differentials  furnished  to  us  were
accepted as factual data and reviewed by us

January 18, 2019
Page 7

for  their  reasonableness;  however,  we  have  not  conducted  an  independent  verification  of  the  data  used  by  Diamondback  to
determine these differentials.

In addition, the table below summarizes the net volume weighted benchmark prices adjusted for differentials and referred
to herein as the “average realized prices.” The average realized prices shown in the table below were determined from the total
future gross revenue before production taxes and the total net reserves for the geographic area and presented in accordance with
SEC disclosure requirements for the geographic areas included in the report.

Costs

As a holder of royalty interests only, Viper bears none of the operating or development costs associated with the underlying
properties  of  this  report.  Nevertheless,  the  proved  undeveloped  reserves  in  this  report  have  been  incorporated  herein  in
accordance  with  Diamondback’s  plans  to  develop  these  reserves  as  of  December  31,  2019.  The  implementation  of
Diamondback’s  development  plans  as  presented  to  us  and  incorporated  herein  is  subject  to  the  approval  process  adopted  by
Diamondback’s management. As the result of our inquiries during the course of preparing this report, Diamondback has informed
us  that  the  development  activities  included  herein  have  been  subjected  to  and  received  the  internal  approvals  required  by
Diamondback’s  management  at  the  appropriate  local,  regional  and/or  corporate  level.  In  addition  to  the  internal  approvals  as
noted,  certain  development  activities  may  still  be  subject  to  specific  partner  AFE  processes,  Joint  Operating  Agreement  (JOA)
requirements  or  other  administrative  approvals  external  to  Diamondback.  Diamondback  has  provided  written  documentation
supporting  their  commitment  to  proceed  with  the  development  activities  as  presented  to  us.  Additionally,  Diamondback  has
informed us that they are not aware of any legal, regulatory, or political obstacles that would significantly alter their plans. While
these  plans  could  change  from  those  under  existing  economic  conditions  as  of  December  31,  2019,  such  changes  were,  in
accordance with rules adopted by the SEC, omitted from consideration in making this evaluation.

PETROLEUM RESERVES DEFINITIONS
Page 1

PETROLEUM RESERVES DEFINITIONS

As Adapted From:
RULE 4-10(a) of REGULATION S-X PART 210
UNITED STATES SECURITIES AND EXCHANGE COMMISSION (SEC)

PREAMBLE

On January 14, 2009, the United States Securities and Exchange Commission (SEC) published the “Modernization of Oil
and  Gas  Reporting;  Final  Rule”  in  the  Federal  Register  of  National  Archives  and  Records  Administration  (NARA).  The
“Modernization  of  Oil  and  Gas  Reporting;  Final  Rule”  includes  revisions  and  additions  to  the  definition  section  in  Rule  4-10  of
Regulation  S-X,  revisions  and  additions  to  the  oil  and  gas  reporting  requirements  in  Regulation  S-K,  and  amends  and  codifies
Industry  Guide  2  in  Regulation  S-K.  The  “Modernization  of  Oil  and  Gas  Reporting;  Final  Rule”,  including  all  references  to
Regulation S-X and Regulation S-K, shall be referred to herein collectively as the “SEC regulations”. The  SEC  regulations  take
effect for all filings made with the United States Securities and Exchange Commission as of December 31, 2009, or after January
1, 2010. Reference should be made to the full text under Title 17, Code of Federal Regulations, Regulation S-X Part 210, Rule 4-
10(a)  for  the  complete  definitions  (direct  passages  excerpted  in  part  or  wholly  from  the  aforementioned  SEC  document  are
denoted in italics herein).

Reserves  are  estimated  remaining  quantities  of  oil  and  gas  and  related  substances  anticipated  to  be  economically
producible, as of a given date, by application of development projects to known accumulations. All reserve estimates involve an
assessment of the uncertainty relating the likelihood that the actual remaining quantities recovered will be greater or less than the
estimated quantities determined as of the date the estimate is made. The uncertainty depends chiefly on the amount of reliable
geologic  and  engineering  data  available  at  the  time  of  the  estimate  and  the  interpretation  of  these  data.  The relative degree of
uncertainty may be conveyed by placing reserves into one of two principal classifications, either proved or unproved. Unproved
reserves  are  less  certain  to  be  recovered  than  proved  reserves  and  may  be  further  sub-classified  as  probable  and  possible
reserves  to  denote  progressively  increasing  uncertainty  in  their  recoverability.  Under  the  SEC  regulations  as  of  December  31,
2009,  or  after  January  1,  2010,  a  company  may  optionally  disclose  estimated  quantities  of  probable  or  possible  oil  and  gas
reserves in documents publicly filed with the SEC. The SEC regulations continue to prohibit disclosure of estimates of oil and gas
resources  other  than  reserves  and  any  estimated  values  of  such  resources  in  any  document  publicly  filed  with  the  SEC  unless
such  information  is  required  to  be  disclosed  in  the  document  by  foreign  or  state  law  as  noted  in  §229.1202  Instruction  to  Item
1202.

Reserves  estimates  will  generally  be  revised  only  as  additional  geologic  or  engineering  data  become  available  or  as

economic conditions change.

Reserves may be attributed to either natural energy or improved recovery methods. Improved recovery methods include all
methods  for  supplementing  natural  energy  or  altering  natural  forces  in  the  reservoir  to  increase  ultimate  recovery.  Examples  of
such methods are pressure maintenance, natural gas cycling, waterflooding, thermal methods, chemical flooding, and the use of
miscible  and  immiscible  displacement  fluids.  Other  improved  recovery  methods  may  be  developed  in  the  future  as  petroleum
technology continues to evolve.

Reserves may be attributed to either conventional or unconventional petroleum accumulations. Petroleum accumulations
are considered as either conventional or unconventional based on the nature of their in-place characteristics, extraction method
applied, or degree of processing prior to sale. Examples of unconventional petroleum accumulations include coalbed or coalseam
methane (CBM/CSM), basin-

RYDER SCOTT COMPANY PETROLEUM CONSULTANTS

PETROLEUM RESERVES DEFINITIONS
Page 2

centered gas, shale gas, gas hydrates, natural bitumen and oil shale deposits. These unconventional accumulations may require
specialized extraction technology and/or significant processing prior to sale.

Reserves do not include quantities of petroleum being held in inventory.

Because  of  the  differences  in  uncertainty,  caution  should  be  exercised  when  aggregating  quantities  of  petroleum  from

different reserves categories.

RESERVES (SEC DEFINITIONS)

Securities and Exchange Commission Regulation S-X §210.4-10(a)(26) defines reserves as follows:

Reserves.  Reserves  are  estimated  remaining  quantities  of  oil  and  gas  and  related  substances  anticipated  to  be  economically
producible, as of a given date, by application of development projects to known accumulations. In  addition,  there  must  exist,  or
there  must  be  a  reasonable  expectation  that  there  will  exist,  the  legal  right  to  produce  or  a  revenue  interest  in  the  production,
installed means of delivering oil and gas or related substances to market, and all permits and financing required to implement the
project.

Note to paragraph (a)(26):  Reserves  should  not  be  assigned  to  adjacent  reservoirs  isolated  by  major,  potentially  sealing,  faults
until those reservoirs are penetrated and evaluated as economically producible. Reserves should not be assigned to areas that
are  clearly  separated  from  a  known  accumulation  by  a  non-productive  reservoir  (i.e.,  absence  of  reservoir,  structurally  low
reservoir,  or  negative  test  results).  Such  areas  may  contain  prospective  resources  (i.e.,  potentially  recoverable  resources  from
undiscovered accumulations).

PROVED RESERVES (SEC DEFINITIONS)

Securities and Exchange Commission Regulation S-X §210.4-10(a)(22) defines proved oil and gas reserves as follows:

Proved oil and gas reserves. Proved oil and gas reserves are those quantities of oil and gas, which, by analysis of geoscience
and engineering data, can be estimated with reasonable certainty to be economically producible-from a given date forward, from
known  reservoirs,  and  under  existing  economic  conditions,  operating  methods,  and  government  regulations-prior  to  the  time  at
which contracts providing the right to operate expire, unless evidence indicates that renewal is reasonably certain, regardless of
whether  deterministic  or  probabilistic  methods  are  used  for  the  estimation.  The  project  to  extract  the  hydrocarbons  must  have
commenced or the operator must be reasonably certain that it will commence the project within a reasonable time.

(i) The area of the reservoir considered as proved includes:

(A) The area identified by drilling and limited by fluid contacts, if any, and

(B) Adjacent undrilled portions of the reservoir that can, with reasonable certainty, be judged to be continuous with
it and to contain economically producible oil or gas on the basis of available geoscience and engineering data.

(ii) In the absence of data on fluid contacts, proved quantities in a reservoir are limited by the lowest known hydrocarbons
(LKH)  as  seen  in  a  well  penetration  unless  geoscience,  engineering,  or  performance  data  and  reliable  technology
establishes a lower contact with reasonable certainty.

(iii)  Where  direct  observation  from  well  penetrations  has  defined  a  highest  known  oil  (HKO)  elevation  and  the  potential
exists for an associated gas cap, proved oil reserves may be assigned in the

structurally  higher  portions  of  the  reservoir  only  if  geoscience,  engineering,  or  performance  data  and  reliable  technology
establish the higher contact with reasonable certainty.

(iv) Reserves which can be produced economically through application of improved recovery techniques (including, but not
limited to, fluid injection) are included in the proved classification when:

(A)  Successful  testing  by  a  pilot  project  in  an  area  of  the  reservoir  with  properties  no  more  favorable  than  in  the
reservoir  as  a  whole,  the  operation  of  an  installed  program  in  the  reservoir  or  an  analogous  reservoir,  or  other
evidence  using  reliable  technology  establishes  the  reasonable  certainty  of  the  engineering  analysis  on  which  the
project or program was based; and

(B) The project has been approved for development by all necessary parties and entities, including governmental
entities.

(v)  Existing  economic  conditions  include  prices  and  costs  at  which  economic  producibility  from  a  reservoir  is  to  be
determined. The price shall be the average price during the 12-month period prior to the ending date of the period covered
by  the  report,  determined  as  an  unweighted  arithmetic  average  of  the  first-day-of-the-month  price  for  each  month  within
such period, unless prices are defined by contractual arrangements, excluding escalations based upon future conditions.

Reserves  status  categories  define  the  development  and  producing  status  of  wells  and  reservoirs.  Reference  should  be
made  to  Title  17,  Code  of  Federal  Regulations,  Regulation  S-X  Part  210,  Rule  4-10(a)  and  the  SPE-PRMS  as  the  following
reserves  status  definitions  are  based  on  excerpts  from  the  original  documents  (direct  passages  excerpted  from  the
aforementioned SEC and SPE-PRMS documents are denoted in italics herein).

DEVELOPED RESERVES (SEC DEFINITIONS)

Securities and Exchange Commission Regulation S-X §210.4-10(a)(6) defines developed oil and gas reserves as follows:

Developed oil and gas reserves are reserves of any category that can be expected to be recovered:

(i)  Through  existing  wells  with  existing  equipment  and  operating  methods  or  in  which  the  cost  of  the  required
equipment is relatively minor compared to the cost of a new well; and

(ii) Through installed extraction equipment and infrastructure operational at the time of the reserves estimate if the
extraction is by means not involving a well.

Developed Producing (SPE-PRMS Definitions)

While  not  a  requirement  for  disclosure  under  the  SEC  regulations,  developed  oil  and  gas  reserves  may  be  further  sub-

classified according to the guidance contained in the SPE-PRMS as Producing or Non-Producing.

Developed Producing Reserves
Developed  Producing  Reserves  are  expected  quantities  to  be  recovered  from  completion  intervals  that  are  open  and
producing at the effective date of the estimate.

Improved recovery reserves are considered producing only after the improved recovery project is in operation.

Developed Non-Producing
Developed Non-Producing Reserves include shut-in and behind-pipe Reserves.

Shut-In
Shut-in Reserves are expected to be recovered from:

(1) completion intervals that are open at the time of the estimate but which have not yet started producing;
(2) wells which were shut-in for market conditions or pipeline connections; or
(3) wells not capable of production for mechanical reasons.

Behind-Pipe
Behind-pipe  Reserves  are  expected  to  be  recovered  from  zones  in  existing  wells  that  will  require  additional  completion
work or future re-completion before start of production with minor cost to access these reserves.

In all cases, production can be initiated or restored with relatively low expenditure compared to the cost of drilling a new
well.

UNDEVELOPED RESERVES (SEC DEFINITIONS)

Securities  and  Exchange  Commission  Regulation  S-X  §210.4-10(a)(31)  defines  undeveloped  oil  and  gas  reserves  as

follows:

Undeveloped  oil  and  gas  reserves  are  reserves  of  any  category  that  are  expected  to  be  recovered  from  new  wells  on
undrilled acreage, or from existing wells where a relatively major expenditure is required for recompletion.

(i)Reserves on undrilled acreage shall be limited to those directly offsetting development spacing areas that are

reasonably certain of production when drilled, unless evidence using reliable technology exists that establishes
reasonable certainty of economic producibility at greater distances.

(ii)  Undrilled  locations  can  be  classified  as  having  undeveloped  reserves  only  if  a  development  plan  has  been
adopted indicating that they are scheduled to be drilled within five years, unless the specific circumstances, justify a
longer time.

(iii) Under no circumstances shall estimates for undeveloped reserves be attributable to any acreage for which an
application  of  fluid  injection  or  other  improved  recovery  technique  is  contemplated,  unless  such  techniques  have
been proved effective by actual projects in the same reservoir or an analogous reservoir, as defined in paragraph
(a)(2) of this section, or by other evidence using reliable technology establishing reasonable certainty.
