Item 1. Business

Overview

PART I

American  Midstream  Partners,  LP  is  a  growth-oriented  Delaware  limited  partnership  that  was  formed  in  August  2009  to  own,  operate,  develop  and  acquire  a
diversified portfolio of midstream energy assets. We provide critical midstream infrastructure that links producers of natural gas, crude oil, NGLs, condensate and
specialty  chemicals  to  numerous  intermediate  and  end-use  markets.  Through  our  five  reportable  segments,  (i)  gas  gathering  and  processing  services,  (ii)  liquid
pipelines  and  services,  (iii)  natural  gas  transportation  services,  (iv)  offshore  pipelines  and  services  and  (v)  terminalling  services,  we  engage  in  the  business  of
gathering, treating, processing, and transporting natural gas; gathering, transporting, storing, treating and fractionating NGLs; gathering, storing and transporting
crude oil and condensates  and storing specialty  chemical products and refined products. As of September 1, 2017, as a result of the disposition of the Propane
Marketing Services business ("Propane Business") described in Note 4 - Discontinued Operations , in Part II, Item 8 of this Annual Report, we have eliminated the
Propane Marketing Services segment.

Our primary assets are strategically located in some of the most prolific onshore and offshore producing regions and key demand markets in the United States. Our
gathering and processing assets are primarily located in (i) the Permian Basin of West Texas, (ii) the Cotton Valley/Haynesville Shale of East Texas, (iii) the Eagle
Ford Shale of South Texas, (iv) the Bakken Shale of North Dakota and (v) offshore in the Gulf of Mexico. Our liquid pipelines, natural gas transportation and
offshore  pipelines  and  terminal  assets  are  located  in  prolific  producing  regions  and  key  demand  markets  in  Alabama,  Arkansas,  Louisiana,  Mississippi,  North
Dakota, Texas, Tennessee and in the Port of New Orleans in Louisiana and the Port of Brunswick in Georgia. Additionally, we operate a fleet of NGL gathering
and  transportation  trucks  in  the  Eagle  Ford  shale  and  the  Permian  Basin.  See  Recent  Developments  for  more  information  about  our  recent  acquisitions  and
dispositions.

We own or have ownership interests in more than 5,100 miles of onshore and offshore natural gas, crude oil, NGL and saltwater pipelines across 17 gathering
systems,  seven  interstate  pipelines  and  nine  intrastate  pipelines;  eight  natural  gas  processing  plants;  four  fractionation  facilities;  an  offshore  semisubmersible
floating  production  system  with  nameplate  processing  capacity  of  90  MBbl/d  of  crude  oil  and  220  MMcf/d  of  natural  gas;  six  marine  terminal  sites  with
approximately  6.7  MMBbls  of  above-ground  aggregate  storage  capacity  for  petroleum  products,  distillates,  chemicals  and  agricultural  products;  and  90  active
transportation trucks and a total trailer fleet of 130, of which 35 are Liquefied Petroleum Gas ("LPG") trailers and 95 are crude oil trailers.

A portion of our cash flow is derived from our investments in unconsolidated affiliates, including a 66.67% operated interest in Destin Pipeline Company, L.L.C.
(“Destin”), a natural gas pipeline; a 35.7% non-operated interest in the Class A units of Delta House FPS LLC ("FPS") and of Delta House Oil and Gas Lateral
LLC ("Lateral") (collectively referred to herein as "Delta House"), which is a floating production system platform and related pipeline infrastructure; a 16.7% non-
operated  interest  in  Tri-States  NGL  Pipeline,  L.L.C.  ("Tri-States"),  an  NGL  pipeline;  a  66.7%  operated  interest  in  Okeanos  Gas  Gathering  Company,  LLC
("Okeanos"), a natural gas pipeline; and a 25.3% non-operated interest in Wilprise Pipeline Company, L.L.C. (“Wilprise”), a NGL pipeline.

We manage our business and analyze and report our results of operations through five reportable segments.

• Gas Gathering and Processing Services. Our Gas Gathering and Processing Services segment provides “wellhead-to-market” services to producers of
natural  gas and NGLs, which include transporting raw natural  gas from various receipt  points through gathering  systems, treating the raw natural  gas,
processing raw natural gas to separate the NGLs from the natural gas, fractionating NGLs, and selling or delivering pipeline quality natural gas and NGLs
to various markets and pipeline systems.

3

• Liquid Pipelines and Services. Our Liquid Pipelines and Services segment provides transportation, purchase and sales of crude oil from various receipt
points including lease automatic customer transfer (“LACT”) facilities and deliveries to various markets.

• Natural Gas Transportation Services. Our Natural Gas Transportation Services segment transports and delivers natural gas from producing wells, receipt
points  or  pipeline  interconnects  for  shippers  and  other  customers,  which  include  local  distribution  companies  (“LDCs”),  utilities  and  industrial,
commercial and power generation customers.

• Offshore Pipelines and Services. Our Offshore Pipelines and Services segment gathers and transports natural gas and crude oil from various receipt
points to other pipeline interconnects, onshore facilities and other delivery points.

•  Terminalling  Services.  Our  Terminalling  Services  segment  provides  above-ground  leasable  storage  operations  at  our  marine  terminals  that  support
various commercial customers, including commodity brokers, refiners and chemical manufacturers to store a range of products and also includes crude oil
storage in Cushing, Oklahoma and refined products terminals in Texas and Arkansas.

Recent Developments

In 2017, we completed the following acquisitions and dispositions:

•

•

•

•

•

•

•

On March 8, 2017, we completed the acquisition of JP Energy Partners LP (“JPE”), an entity controlled by affiliates of ArcLight Capital Partners, LLC
(“ArcLight”), in a unit-for-unit merger (the “JPE Merger”). In connection with the transaction, each JPE common or subordinated unit held by investors
not affiliated with ArcLight was converted into the right to receive 0.5775 of a Partnership common unit, and each JPE common or subordinated unit held
by ArcLight affiliates was converted into the right to receive 0.5225 of a Partnership common unit. We issued a total of 20.2 million of our common units
to complete the acquisition, including 9.8 million common units to ArcLight affiliates.

On June 2, 2017, we acquired 100% of the Viosca Knoll Gathering System (“VKGS”) from Genesis Energy, L.P. for total consideration of approximately
$32 million in cash.

On  August  8,  2017,  we  acquired  100%  of  the  interest  in  Panther  Offshore  Gathering  Systems,  LLC  (“POGS”),  Panther  Pipeline,  LLC  (“PPL”)  and
Panther  Operating  Company,  LLC  (“POC”  and,  together  with  POGS  and  PPL,  “Panther”)  from  Panther  Asset  Management  LLC  (“Panther  Asset
Management”)  for  approximately  $60.9  million.  The  consideration  included  $39.1  million  cash,  funded  from  borrowings  under  our  revolving  credit
facility, and the issuance of common units, valued at $12.5 million based on unit value as of the acquisition date.

On September 1, 2017, we completed the disposition of our Propane Business pursuant to the Membership Interest Purchase Agreement dated July 21,
2017, between our wholly-owned subsidiary AMID Merger LP, and SHV Energy N.V.

On  September  29,  2017,  we  acquired  an  additional  15.5%  equity  interest  in  Class  A  units  of  Delta  House  from  affiliates  of  ArcLight  for  total  cash
consideration of approximately $125.4 million.

On  October  27,  2017,  our  wholly-owned  subsidiary,  American  Midstream  Emerald,  LLC,    entered  into  a  Purchase  and  Sale  Agreement  with  Emerald
Midstream,  LLC,  an  ArcLight  affiliate,  to  purchase  an  additional  17.0%  equity  interest  in  Destin  for  total  consideration  of  $30.0  million.    With  the
acquisition, we now own a 66.67% interest in Destin.

On November 6, 2017, we acquired 100% of the equity interests in Trans-Union Interstate Pipeline, LP (“Trans-Union”) from affiliates of ArcLight, for a
total consideration of approximately $49.4 million. The consideration consisted of approximately $16.9 million cash funded from borrowings under our
revolving credit facility and the assumption of $32.5 million of non-recourse debt.

See Note 3 - Acquisitions, Note 4 - Discontinued Operations and Note 25 - Subsequent Events in Part II, Item 8 of this Annual Report for additional information.

Pending Southcross Energy Partners, L.P. Merger

On  October  31,  2017,  we,  our  General  Partner,  our  wholly  owned  subsidiary,  Cherokee  Merger  Sub  LLC  (“Merger  Sub”),  Southcross  Energy  Partners,  L.P.
(“SXE”), and Southcross Energy Partners GP, LLC (“SXE GP”), entered into an Agreement and Plan of Merger (the “SXE Merger Agreement”). Upon the terms
and subject to the conditions set forth in the SXE Merger Agreement, SXE will merge with Merger Sub (the “SXE Merger”), with SXE continuing its existence
under Delaware law as the surviving entity in the SXE Merger and wholly owned subsidiary of us.

At the effective time of the SXE Merger (the “Effective Time”), each common unit of SXE (each, an “SXE Common Unit”) issued and outstanding or deemed
issued and outstanding as of immediately prior to the Effective Time will be converted into the right to receive 0.160 (the “Exchange Ratio”) of a common unit
(each, an “AMID Common Unit”) representing limited partner interests in us (the “Merger Consideration”), except for those SXE Common Units held by affiliates
of SXE and SXE GP, which will be canceled for no consideration. Each SXE Common Unit, Subordinated Unit (as defined in the SXE Merger Agreement) and
Class  B Convertible  Unit  (as  defined  in  the  SXE Merger  Agreement)  held  by Southcross  Holdings  LP (“Holdings  LP”)  or  any  of  its  subsidiaries  and  the  SXE
Incentive Distribution Rights (as defined in the SXE Merger Agreement) outstanding immediately prior to the Effective Time will be canceled in connection with
the closing of the SXE Merger.

In connection with the SXE Merger Agreement, on October 31, 2017, we and our General Partner entered into a Contribution Agreement (the “SXE Contribution
Agreement” and, together with the SXE Merger Agreement, the “SXE Transaction Agreements”) with Holdings LP. Upon the terms and subject to the conditions
set forth in the SXE Contribution Agreement, Holdings LP will contribute its equity interests in its new wholly owned subsidiary (“SXH Holdings”), which will
hold  substantially  all  the  current  subsidiaries  (Southcross  Holdings  Intermediary  LLC,  Southcross  Holdings  Guarantor  GP  LLC  and  Southcross  Holdings
Guarantor  LP)  and  business  of  Holdings  LP,  to  us  and  our  General  Partner  in  exchange  for  (i)  the  number  of  AMID  Common  Units  with  a  value  equal  to
$185,697,148, subject to certain adjustments for cash, indebtedness, working capital and transaction expenses contemplated by the SXE Contribution Agreement,
divided  by  $13.69  per  AMID  Common  Unit,  (ii)  4,500,000  AMID  Preferred  Units  (as  defined  in  the  SXE  Contribution  Agreement),  (iii)  options  to  purchase
4,500,000  AMID  Common  Units  (the  “Options”),  and  (iv)  3,000  AMID  GP  Class  D  Units  (as  defined  in  the  SXE  Contribution  Agreement)  (the  transactions
contemplated thereby and the agreements ancillary thereto, the “SXE Contribution” and together with the SXE Merger, the “SXE Transactions”). A portion of the
consideration will be deposited into escrow in order to secure certain post-closing obligations of Holdings LP. Concurrently with the closing of the transaction, our
agreement of limited partnership will be amended to reflect the issuance of AMID Preferred Units, and the GP LLC Agreement will be amended to reflect the
issuance of such AMID GP Class D Units.

As disclosed in the Registration statement on Form S-4, as filed with the Securities and Exchange Commission ("SEC") on January 11, 2018, the SXE Merger has
a total aggregate consideration of $817.9 million, including a total assumed debt of $644.6 million.

Other developments

In the fourth quarter of 2017, we were notified by the operator of Delta House FPS that certain third party-owned upstream infrastructure would require remedial
work, resulting in a temporary delay of production volumes flowing into Delta House. This remediation is scheduled to be completed later in the second quarter of
2018, at which time full production is anticipated to resume flowing into Delta House. This has resulted in a reduction in cash distributions from Delta House,
including those attributable to our 35.7% interest, during the curtailment.

On  March  11,  2018,  we  and  Magnolia  Infrastructure  Holdings,  LLC  ("Magnolia"),  an  affiliate  of  ArcLight,  entered  into  a  Capital  Contribution  Agreement  to
provide additional capital and corporate overhead support to us during the first three quarters of 2018 in connection with temporary curtailment of production flows
at Delta House. Pursuant to the agreement, Magnolia has agreed to provide support to us in an amount to be agreed, up to the difference between the actual cash
distribution received by us on account of our interest in Delta House and the quarterly cash distribution expected to be received if production flows to Delta House
had not been not curtailed.

On February 16, 2018, we announced the sale of the Refined Products Terminals (the "Refined Products Business") consisting of two terminal facilities, located in
Caddo  Mills,  Texas  ("Caddo  Mills")  and  North  Little  Rock,  Arkansas  ("NLR"),  to  DKGP  Energy  Terminals  LLC,  a  joint  venture  between  Delek  Logistics
Partners, LP and Green Plains Partners LP, for approximately $138.5 million in cash, subject to working capital adjustments. Closing of the sale of the Refined
Products Business is subject to customary closing conditions, including clearance under the Hart-Scott-Rodino Act. The transaction is expected to close in the first
half of 2018.

Market Conditions

Average daily prices for New York Mercantile Exchange ("NYMEX") West Texas Intermediate ("WTI") crude oil ranged from a high of $ 66.27 per barrel to a
low of $42.48 per barrel from January 1, 2017 through March 26, 2018 . Average daily prices for NYMEX Henry Hub natural gas ranged from a high of $6.24 per
MMBtu to a low of $2.44 per MMBtu from January 1, 2017 through March 26, 2018 .

Fluctuations in energy prices can greatly affect the development of new crude oil and natural gas reserves. Further increases in commodity prices of crude oil and
natural gas, as observed through the later part of 2017, could have a positive impact on exploration, development and production activity, and, if sustained, could
lead  to  a  material  increase  in  such  activity.  Sustained  expansion  or  reductions  in  exploration  or  production  activity  in  our  areas  of  operation  would  lead  to
continued or further increased or reduced utilization of our assets. We are unable to predict future potential movements in the market price for natural gas, crude oil
and NGLs and thus, cannot predict the ultimate impact of commodity prices on our operations.

Business Strategies

Our business objectives continue to focus on maintaining stable cash flows from our existing assets and executing on growth opportunities to increase our long-
term cash flows on a per unit basis. We believe the key elements to stable cash flows are the diversity of our asset portfolio and our fee-based business which
represents a significant portion of our estimated margins, the objective of which is to protect against downside risk in our cash flows.

Utilize our strategically  located  and integrated assets to maximize value for our customers.  We own and operate a portfolio of midstream assets strategically
located in some of the most prolific natural gas and crude oil producing regions and key demand markets in the United States and offshore in the Gulf of Mexico.
Through our diversified and integrated asset base, we provide critical infrastructure that links producers of natural gas, crude oil, NGLs, condensate and specialty
chemicals to numerous intermediate and end-use markets while allowing us to generate revenue and service the same energy molecules at various stages along the
midstream value chain.

Enhance  existing  assets  and  realize  operating  efficiencies.  We  intend  to  enhance  the  profitability  of  our  assets  by  increasing  utilization,  realizing  operating
efficiencies and providing additional midstream services desired by our customers. We continually seek to attract new volumes from existing and new customers
through superior customer service and asset optimization. In addition, we expect to be able to provide additional midstream services to our customers by cross-
selling  complementary  services.  For  example,  we  intend  to  leverage  our  crude  oil  and  NGL  trucking  capabilities  across  our  onshore  gathering  and  processing
footprint  and  expand  our  service  offering  in  the  Permian  Basin  and  Cotton  Valley/Haynesville  Shale.  We  can  accommodate  additional  volumes  at  minimal
incremental cost, which provides highly attractive economics.

Capitalize on organic growth opportunities. We continually seek to identify and evaluate economically attractive organic expansion opportunities that leverage
our asset footprint and strategic relationships with our customers. These organic projects include new interconnects, repurposing underutilized assets and adding
additional capacity to meet increased demand from our customers. 

Pursue accretive acquisitions. We plan to pursue accretive acquisitions of complementary midstream assets that will allow us to increase market share and density
in our core operating areas and realize operational efficiencies and commercial synergies. Future acquisition opportunities may include bolt-on acquisitions within
our asset footprint, consolidation of third party interests in our joint ventures and strategic acquisitions. Our partnership with ArcLight may present us with future
drop-down opportunities and the ability to jointly pursue third party acquisitions that may not otherwise be feasible on a stand-alone basis.

Maintain focus on stable, fee-based and fixed-margin cash flow with minimal direct exposure to commodity prices. We seek to minimize our direct commodity
price exposure and maintain stable cash flow by generating a substantial portion of our total gross margin pursuant to fee-based and fixed-margin contracts. We
have been successful executing on this strategy and have increased the percentage of gross margin generated from fee-based and fixed-margin contracts for the
fiscal years ended December 31, 2017 and 2016, respectively.

Maintain a conservative and flexible capital structure. We plan to pursue a disciplined financial policy and maintain a conservative capital structure to allow us to
pursue additional organic growth projects and acquisitions, with a conservative mix of debt and equity, even in challenging market environments.

Competitive Strengths

We believe we are well-positioned to successfully execute our strategy because of the following competitive strengths:

Stable and predictable cash flows supported by fee-based and fixed-margin contracts. Substantially all of our transmission and terminal assets are contracted on a
firm transportation or take-or-pay basis and a majority of our offshore assets are contracted under long-term, life-of-lease dedications. We believe that the nature of
our contracts minimizes our direct commodity price exposure and enhances the stability of our business and the predictability of our financial performance.

Diversified and strategically located portfolio of midstream assets. Our assets are diversified geographically and by business line, which contribute to the stability
of our cash flows. We operate throughout many of the most prolific crude oil and natural gas producing regions in the United States and offshore Gulf of Mexico.
We have access to multiple sources of crude oil, natural gas and liquids and are in close proximity to various interstate and intrastate pipelines as well as utility,
industrial and other commercial end users. Our diverse and creditworthy customer base includes several large producers, refiners and marketers.

Significant scale and capability. As of December 31, 2017, after giving effect to the JPE Merger and other acquisitions, we have approximately $1.9 billion in
total assets across the midstream value chain providing onshore and offshore crude oil and natural gas gathering, processing, transmission and storage as well as
hydrocarbon  and  refined  product  terminal  assets  and  NGL  fractionation,  distribution  and  sales.  Following  the  closing  of  the  JPE  Merger,  we  own  or  have  an
ownership interest in approximately 5,100 miles of onshore and offshore natural gas, crude oil, NGL and saltwater pipelines across 17 gathering systems, seven
interstate pipelines and nine intrastate pipelines; eight natural gas processing plants; four fractionation facilities; an offshore semi-submersible floating production
system with nameplate processing capacity of 90 MBbl/d of crude oil and 220 MMcf/d of natural gas; six marine terminal sites with approximately 6.7 MMBbls of
above-ground storage capacity; and 90 transportation trucks and a total trailer fleet of 130, of which 35 are LPG trailers and 95 are crude oil trailers. We believe
our size, scale and capabilities enhance our ability to serve our customers and provide financial flexibility and an increased ability to access the capital markets.

Strategically located offshore position with high barriers to entry. We have a substantial footprint in the deepwater Gulf of Mexico with our ownership interest in
the Delta House platform and associated assets. This state-of-the-art floating, production and storage facility is located in one of the most active parts of the deep-
water Gulf of Mexico and we have well-established relationships and long-term agreements with key participants along the entire value chain in the region. We
believe producers in the areas of the Gulf of Mexico in which we operate are motivated to connect their production to our existing pipelines as construction of new
pipelines  is  often  not  feasible  due  to  cost  and  timing  considerations.  In  addition,  we  have  acquired  additional  strategic  assets  that  provide  us  with  substantial
operational  flexibility  including  multiple  delivery  and  offload  points  as  we  move  hydrocarbons  from  source  to  market,  allowing  us  to  provide  a  valuable  and
differentiated service to our customers.

Relationship  with  ArcLight.  Our  relationship  with  ArcLight  provides  us  with  access  to  ArcLight’s  extensive  operational  and  commercial  expertise.  ArcLight
indirectly owns 48.6% of our limited partner interests and 100% of the IDRs. We believe that ArcLight is economically incentivized to promote and support our
business plan and to pursue projects that enhance the overall value of our business.

Experienced  management  and  operational  teams.  Our  executive  management  team  has  an  average  of  approximately  20  years  of  experience  in  the  midstream
energy  industry.  The  team  possesses  a  comprehensive  skill  set  to  support  our  business  and  execute  our  business  strategy  through  asset  optimization,  accretive
development projects and acquisitions.

Our Segments

AMID  manages  its  business  under  five  distinct  operating  segments:  Gas  Gathering  and  Processing  Services,  Liquid  Pipelines  and  Services,  Natural  Gas
Transportation  Services,  Offshore  Pipelines  and  Services  and Terminalling  Services.  Each  segment  is explained  below along  with  description  of  the assets  that
support each of those segments.

Gas Gathering and Processing (G&P) Services Segment

Results of operations  from the  Gas Gathering and Processing Services segment  are determined  primarily  by the volumes of natural  gas we gather,  process and
fractionate,  the  commercial  terms  in  our  current  contract  portfolio  and  natural  gas,  crude  oil,  NGL  and  condensate  prices.  We  gather  and  process  natural  gas
primarily pursuant to the following arrangements:

7

    
Fee-Based Arrangements . Under these arrangements, we generally are paid a fixed fee for gathering, processing and transporting natural gas.

Fixed-Margin Arrangements . Under these arrangements, we purchase natural gas and off-spec condensate from producers or suppliers at receipt points
on  our  systems  at  an  index  price  less  a  fixed  transportation  fee  and  simultaneously  sell  an  identical  volume  of  natural  gas  or  off-spec  condensate  at
delivery  points  on  our  systems  at  the  same,  undiscounted  index  price.  By  entering  into  back-to-back  purchases  and  sales  of  natural  gas  or  off-spec
condensate, we are able to lock in a fixed margin on these transactions. We view the segment gross margin earned under our fixed-margin arrangements
to be economically equivalent to the fee earned in our fee-based arrangements.

Percent-of-Proceeds  Arrangements  (“POP”).  Under  these  arrangements,  we  generally  gather  raw  natural  gas  from  producers  at  the  wellhead  or  other
supply points, transport  it through  our gathering  system,  process it and sell the residue natural  gas, NGLs and condensate  at market  prices.  Where we
provide  processing  services  at  the  processing  plants  that  we  own,  or  obtain  processing  services  for  our  own  account  in  connection  with  our  elective
processing arrangements, we generally retain and sell a percentage of the residue natural gas and resulting NGLs. However, we also have contracts under
which we retain a percentage of the resulting NGLs and do not retain a percentage of residue natural gas. Our POP arrangements also often contain a fee-
based component.

Gross margin  earned  under  fee-based  and fixed-margin  arrangements  is directly  related  to the volume  of natural  gas  that  flows through  our systems  and  is not
directly dependent on commodity prices. However, a sustained decline in commodity prices could result in a decline in throughput volumes from producers and,
thus,  a  decrease  in  our  fee-based  and  fixed-margin  gross  margin.  These  arrangements  provide  stable  cash  flows,  but  upside  in  higher  commodity-price
environments is limited to an increase in throughput volumes from producers. Under our typical POP arrangement, our gross margin is directly impacted by the
commodity prices we realize on our share of natural gas and NGLs received as compensation for processing raw natural gas. However, our POP arrangements
often contain a fee-based component, which helps to mitigate the degree of commodity-price volatility we could experience under these arrangements. We further
seek to mitigate our exposure to commodity price risk through our hedging program. See the information set forth in Part II, Item 7A of this Report under the
caption - Quantitative and Qualitative Disclosures about Market Risk - Commodity Price Risk.

Our Gas Gathering and Processing Services assets are located in Alabama, Louisiana, Mississippi, and Texas and in shallow state and federal waters in the Gulf of
Mexico off the coast of Louisiana and are positioned in areas with opportunities for organic growth. We continually seek new sources of raw natural gas and crude
oil supply to maintain and increase the throughput volume on our gathering systems and through our processing plants.

We generally derive revenue in our Gas Gathering and Processing Services segment from fee-based, fixed-margin and POP arrangements, for our producer and
supplier customers and our own account. For the year ended December 31, 2017, our fee-based, fixed-margin arrangements and our POP arrangements accounted
for approximately 59.1% and 40.9%, respectively, of our segment gross margin for the Gathering and Processing Services segment.

In our G&P segment, we have the following assets:

Liquid Pipelines and Services Segment

Results  of  operations  from  the  Liquid  Pipelines  and  Services  segment  are  determined  by  the  volumes  of  crude  oil  transported  on  the  interstate  and  intrastate
pipelines we own. Tariffs associated with our Bakken system are regulated by FERC for volumes gathered via pipeline and trucked to the AMID Truck facility in
Watford City, North Dakota. Volumes transported on our Silver Dollar system are underpinned by long-term, fee-based contracts. Our transportation arrangements
are further described below:

Firm  Transportation  Arrangements  . Our obligation  to  provide  firm  transportation  service  means  that,  pursuant  to the agreement  with the  shipper,  we
transport crude oil nominated by the shipper up to the maximum daily quantity specified in the contract. In exchange for that obligation on our part, the
shipper pays a specified reservation charge, whether or not the shipper utilizes the capacity. In most cases, the shipper also pays a variable-use charge
with respect to quantities actually transported by us.

Uncommitted Shipper Arrangements . Our obligation to provide interruptible transportation service means that we are only obligated to transport crude oil
nominated by the shipper to the extent that we have available capacity. For this service the shipper pays no reservation charge but pays a variable-use or
commodity charge for quantities actually shipped.

Fee-Based  Arrangements  . Under  these  arrangements  our  operations  are  underpinned  by  long-term,  fee-based  contracts  with  leading  producers  in  the
Midland Basin. Some of these contracts also have minimum volume commitments as well as some have acreage dedications.

Buy-Sell Arrangements. We enter into outright purchase and sales contracts as well as buy/sell contracts with counterparties, under which contracts we
gather and transport different types of crude oil and eventually sell the crude oil to either the same counterparty or different counterparties. We account
for such revenue arrangements on a gross basis. Occasionally, we enter into crude oil inventory exchange arrangements with the same counterparty which
the purchase and sale of inventory are considered in contemplation of each other. Revenues from such inventory exchange arrangements are recorded on a
net basis.

Following are brief descriptions of the assets that make up the Liquid Pipelines and Services segment:

Bakken System

The Bakken crude oil gathering pipeline  system consists of a 43-mile pipeline  with capacity  to transport  up to approximately  40,000 Bbls/d of crude oil to the
Tesoro  Logistics  pipeline  located  Northeast  of  Watford  City,  North  Dakota  and  a  planned  interconnect  with  the  Energy  Transfer  Dakota  Access  Pipeline.  The
system, which commenced operations in October 2015, provides producers in the area with access to refinery, rail and pipeline markets. The system also has the
capability to receive volumes through its truck rack, which also commenced operations in November 2015.

Silver Dollar Pipeline

The Silver Dollar Pipeline is located in the Permian basin and with capacity to transport approximately 130,000 Bbls/d of crude oil. The pipeline was constructed

NGL trucks that assist our marketing efforts.  

Other Systems

Tri-States, Cayenne and Wilprise are also part of the Liquid Pipelines and Services segment and are listed under Investment in Unconsolidated Affiliates below.

Natural Gas Transportation Services Segment

Results of operations from the Natural Gas Transportation Services segment are determined by a capacity reservation charge from firm transportation contracts, a
variable-use or commodity charge for firm and interruptible transportation contracts and the volumes

10

    
    
        
of natural gas transported on the interstate  and intrastate  pipelines we own pursuant to interruptible  transportation or fixed-margin contracts. Our transportation
arrangements are further described below:

Firm  Transportation  Arrangements.  Our  obligation  to  provide  firm  transportation  service  means  that,  pursuant  to  the  agreement  with  the  shipper,  we
transport natural gas nominated by the shipper up to the maximum daily quantity specified in the contract. In exchange for that obligation on our part, the
shipper  pays  a  specified  reservation  charge,  whether  or  not  the  shipper  utilizes  the  capacity.  In  most  cases,  the  shipper  also  pays  a  variable-use  or
commodity charge with respect to quantities actually transported by us.

Interruptible Transportation Arrangements. Our obligation to provide interruptible transportation service means that, pursuant to the agreement with the
shipper,  we  only  transport  natural  gas  nominated  by  the  shipper  to  the  extent  that  we  have  available  capacity.  For  this  service  the  shipper  pays  no
reservation charge but pays a variable-use or commodity charge for quantities actually shipped.

Fixed-Margin Arrangements. Under these arrangements, we purchase natural gas from producers or suppliers at receipt points on our systems at an index
price less a fixed transportation fee and simultaneously sell an identical volume of natural gas at delivery points on our systems at the same undiscounted
index price. We view fixed-margin arrangements to be economically equivalent to our interruptible transportation arrangements.

Following are brief descriptions of the assets that make up the Natural Gas Transportation Services segment:

Midla and MLGT Systems

Our  Midla  System  is  a  FERC-regulated  interstate  natural  gas  pipeline.  On  April  16,  2015,  the  FERC  approved  the  Midla  Agreement  between  Midla  and  its
customers allowing Midla to retire the existing 1920's pipeline, which was comprised of approximately 355 miles of pipeline ranging in diameter from two to 22
inches  and  linked  the  Monroe  Natural  Gas  Field  in  northern  Louisiana  and  interconnections  with  the  Transco  Pipeline  System  to  customers  in  Mississippi  and
Louisiana,  and  replace  the  existing  natural  gas  service  with  a  new  52-mile,  high  pressure  12-inch  pipeline  (the  Midla-Natchez  Line)  to  serve  long-standing
residential,  commercial,  and  industrial  customers.  Under  the  Midla  Agreement,  customers  not  served  by  the  new  Midla-Natchez  Line  were  connected  to  other
interstate or intrastate pipelines, other gas distribution systems, or offered conversion to propane service. On June 29, 2015, the Partnership filed for authorization
to construct the Midla-Natchez pipeline with the FERC, which was approved on December 17, 2015. Construction commenced in the second quarter of 2016 and
service on the Midla-Natchez line began on March 31, 2017. Under the Midla Agreement, Midla executed multiple long-term agreements seeking to recover its
investment in the Midla-Natchez Line. As of December 2017, the 1920’s vintage pipeline was inactive.

Offshore Pipelines and Services Segment

Results  of  operations  from  the  Offshore  Pipelines  and  Services  segment  are  determined  by  capacity  reservation  fees  from  firm  and  interruptible  transportation
contracts  and  the  volumes  of  natural  gas  transported  on  the  interstate  and  intrastate  pipelines  we  own  pursuant  to  interruptible  transportation  or  fixed-margin
contracts. Our transportation arrangements are further described below:

Firm  Transportation  Arrangements.  Our  obligation  to  provide  firm  transportation  service  means  that,  pursuant  to  the  agreement  with  the  shipper,  we
transport natural gas nominated by the shipper up to the maximum daily quantity specified in the contract. In exchange for that obligation on our part, the
shipper pays a specified reservation charge, whether or not the shipper utilizes the capacity. In most cases, the shipper also pays a variable-use charge
with respect to quantities actually transported by us.

Interruptible Transportation Arrangements. Our obligation to provide interruptible transportation service means that, pursuant to the agreement with the
shipper,  we  only  transport  natural  gas  nominated  by  the  shipper  to  the  extent  that  we  have  available  capacity.  For  this  service  the  shipper  pays  no
reservation charge but pays a variable-use charge for quantities actually shipped.

Fixed-Margin Arrangements. Under these arrangements, we purchase natural gas from producers or suppliers at receipt points on our systems at an index
price less a fixed transportation fee and simultaneously sell an identical volume of natural gas at delivery points on our systems at the same undiscounted
index price. We view fixed-margin arrangements to be economically equivalent to our interruptible transportation arrangements.

Delta  House,  Destin  and  Okeanos  are  also  part  of  the  Offshore  Pipelines  and  Services  segment  and  are  listed  under  Investments  in  Unconsolidated  Affiliates
below.

Terminalling Services Segment

Our Terminalling Services segment provides above-ground leasable storage services at our marine terminals that support various commercial customers, including
commodity  brokers,  refiners  and  chemical  manufacturers  to  store  a  range  of  products,  including  petroleum  products,  distillates,  chemicals  and  agricultural
products. We generally receive fee-based compensation on guaranteed firm storage contracts, throughput fees charged to our customers when their products are
either received or disbursed and other fee-based charges associated with ancillary services provided to our customers, such as excess throughput, truck weighing,
etc. Our firm storage contracts are typically multi-year contracts with renewal options.

Our  Terminalling  Services  segment  consists  of  approximately  2.4  million  barrels  of  storage  capacity  across  three  marine  terminal  sites  located  in  Westwego,
Louisiana; Brunswick, Georgia; and Harvey, Louisiana and 3.0 million barrels of storage capacity at

13

Cushing, Oklahoma. Our refined products terminals in North Little Rock, Arkansas and Caddo Mills, TX provide butane blending capabilities.

Following are brief descriptions of the assets that make up the Terminalling Services segment:

Westwego Terminal Operations

The  Westwego  Terminal  site  consists  of  48  above-ground  storage  tanks  with  a  combined  capacity  of  1,044,600  barrels.  Our  operations  support  many  different
commercial  customers,  including  commodity  brokers,  refiners  and  chemical  manufacturers.  Our  location  within  the  Port  of  New  Orleans,  the  warehousing  and
international distribution attributes this location provides, along with our broad customer base, contributes to the potential diversity of the products customers may
want stored in our terminal. The products will generally fall into two broad categories: chemical and agricultural.

Our income from the Westwego Terminal is derived from storage capacity contracts, throughput charges for receipt and delivery of our customers' products; and
other services requested by our customers, such as blending services. The terms of our storage capacity contracts range from month-to-month to multiple years,
with renewal options.

At  the  Westwego  Terminal,  we  generally  receive  our  customers'  liquid  product  by  river  vessel  at  our  Mississippi  River  dock  and  by  railcar.  The  product  is
transferred  from  the  river  vessels  and railcars  to  the  specified  storage  tank  via  the terminal's  internal  pipeline  system.  The  customer's  product  is removed  from
storage at our terminal by truck, railcar and/or water vessel. The length of time that the customer's product is held in storage without transfer varies depending upon
the customer's needs.

Brunswick Terminal Operations

The Brunswick Terminal site consists of one 60,000-barrel above-ground storage tank, two 80,000-barrel above-ground storage tanks and two 500-barrel above-
ground storage tanks with a combined capacity of 221,000 barrels. The Brunswick Terminal is currently leasing land from the Georgia Ports Authority pursuant to
a lease that is in effect until April 2026.

This terminal  is ideally  suited  to serve  petroleum,  chemical  and agricultural  customers  who need deep-water  access  and distribution  in the southeastern  United
States. Income from the Brunswick Terminal is derived from storage capacity contracts, throughput charges for receipt and delivery of our customers' products and
other  services  requested  by  our  customers,  such  as  blending  services.  The  terms  of  our  storage  capacity  contracts  will  range  from  month-to-month  to  multiple
years, with renewal options.

At the Brunswick Terminal,  we offer product  transfer  via river vessel,  railcar  and bulk-liquid  carrying  truck.  At the  Brunswick Terminal,  the customer's  liquid
product is received by barge or ship at the dock. The product is transferred from barges or ships to the storage tank via the terminal's internal pipeline system. The
customer's  product  is  removed  from  storage  at  our  terminal  by  truck  or  railcar.  The  length  of  time  that  the  customer's  product  is  to  be  held  in  storage  without
transfer will vary depending on the customer's needs.

Harvey Terminal Operations

The  Harvey  Terminal  is  located  on  56  acres  on  the  west  bank  of  the  Mississippi  River  in  the  Port  of  New  Orleans  and  equipped  to  handle  a  wide  variety  of
petroleum and chemical products. Terminal storage operations at the Harvey Terminal commenced in July 2014 and currently consists of 34 above-ground storage
tanks with a combined capacity of approximately 1,135,200 barrels. The Harvey Terminal is a full-service storage site, including 3,000 feet of rail track that can
accommodate up to 50 cars and a two bay semi-automated truck loading facility. At the Harvey Terminal, we generally receive our customers' liquid product by
river  vessel  at  our  Mississippi  River  dock  and  by  railcar.  The  product  is  transferred  from  the  river  vessels  and  railcars  to  the  specified  storage  tank  via  the
terminal's internal pipeline system. The customer's product is removed from storage at our terminal by truck, railcar and/or water vessel. When fully developed, the
Harvey Terminal has the potential to provide more than 2 million barrels of storage capacity.

Cushing

Our crude oil storage facility in Cushing, Oklahoma has an aggregate shell capacity of approximately 3.0 million barrels. We generate crude oil storage revenues
by charging customers a fixed monthly fee per barrel of shell capacity that is not contingent on the customer's actual usage of our storage tanks, i.e., take-or-pay
firm storage contracts.

14

North Little Rock and Caddo Mills

Our refined products terminals have aggregate storage capacity of approximately 1.3 million barrels at two refined products terminals located in North Little Rock,
Arkansas and Caddo Mills, Texas. Our North Little Rock terminal has storage capacity of approximately 550,000 barrels from 11 tanks and is primarily supplied
by  a  refined  products  pipeline  operated  by  Enterprise  TE  Products  Pipeline  Company  LLC.  Our  Caddo  Mills  terminal  has  storage  capacity  of  approximately
770,000 barrels from 10 tanks and is primarily supplied by the Explorer Pipeline. We generate fee-based loading revenues with customers under contracts that,
consistent with industry practice, typically contain evergreen provisions after an initial term of six months to two years. We also generate revenue from (i) blending
activities,  such  as  ethanol  blending  and  butane  blending,  and  (ii)  our  vapor  recovery  units.  A  majority  of  the  customers  in  our  refined  products  terminals  and
storage segment are large, well-known oil companies and independent refiners.

On  February  16,  2018,  we  entered  into  a  definitive  agreement  for  the  sale  of  our  refined  products  terminals  to  DKGP  Energy  Terminals  LLC,  a  joint  venture
between Delek Logistics Partners, LP and Greens Plains Partners LP, for approximately $138.5 million in cash, subject to working capital adjustments. Closing of
the sale is subject to customary closing conditions, including clearance under the Hart-Scott-Rodino Act. The transaction is expected to close in the first half of
2018.

Investments in Unconsolidated Affiliates

Delta House

On September 29, 2017, we acquired an additional 15.5% equity interest in Class A units of Delta House, from affiliates of ArcLight for total cash consideration of
approximately $125.4 million. Post-closing, we and ArcLight indirectly own a 35.7% and 23.3% interest, respectively, in Delta House.

Delta House is a semi-submersible floating production system with associated crude oil and natural gas export pipelines located in the Mississippi Canyon region
of the deepwater Gulf of Mexico. The semi-submersible floating production system receives raw production from deepwater wells, which includes a mixture of
crude  oil,  natural  gas,  and  produced  water,  and  separates  the  production  into  its  components.  The  separated  crude  oil  and  natural  gas  pressures  are  increased,
creating  pipeline  quality  crude  oil  and  natural  gas  that  flows  into  the  respective  crude  oil  and  natural  gas  export  pipelines.  Delta  House  is  operated  by  LLOG
Exploration  Offshore,  LLC  ("LLOG  Exploration")  and  has  nameplate  processing  capacity  of  80,000  Bbl/d  and  200  MMcf/d  and  peak  processing  capacity  of
100,000 Bbl/d and 240 MMcf/d.

Cayenne JV

On August 8, 2017, we entered into a joint venture agreement with Targa Midstream Services, LLC (“Targa”) by which our previously wholly owned subsidiary
Cayenne Pipeline, LLC (“Cayenne”) became the Cayenne joint venture between Targa and us (“Cayenne JV”). We received $5.0 million in cash in exchange for
the sale of 50% ownership interest in Cayenne to Targa. The sole asset of the joint venture is a natural gas pipeline, which has been converted into a natural gas
liquids pipeline. Both parties will each have 50% economic interests and 50% voting rights, with Targa serving as the operator of the pipeline and the joint venture.
The additional costs of conversion and associated construction are shared equally by us and Targa. The pipeline became operational on December 28, 2017.

Okeanos

We  own  a  66.7%  operated  interest  in  Okeanos,  a  100-mile  natural  gas  gathering  system  located  in  the  Gulf  of  Mexico  with  a  total  capacity  of  1.0  Bcf/d.  The
Okeanos  pipeline  connects  two  platforms  and  one  lateral,  terminating  at  the  Destin  Main  Pass  260  platform  in  the  Mississippi  Canyon  region  of  the  Gulf  of
Mexico. Contracted volumes on the Okeanos pipeline are based on life-of-field dedication.

Destin

On  October  27,  2017,  American  Midstream  Emerald,  LLC,  a  wholly-owned  subsidiary  of  the  Partnership,  entered  into  a  Purchase  and  Sale  Agreement  with
Emerald Midstream, LLC, an ArcLight affiliate, to purchase an additional 17.0% equity interest in Destin Pipeline Company, LLC for total consideration of $30.0
million.  With the acquisition, the Partnership owns a 66.67% interest in Destin.  The Destin pipeline is a FERC-regulated, 255-mile natural gas transport system
with total capacity of 1.2 Bcf/d. The system originates offshore in the Gulf of Mexico and includes connections with four producing platforms, and six producer-
operated laterals, including Delta House. The 120-mile offshore portion of the Destin system terminates at the Pascagoula processing plant, owned by Enterprise
Products Partners, LP, and is the single source of raw natural gas to the plant. The onshore portion of

15

Destin is the sole delivery point for merchant-quality gas from the Pascagoula processing plant and extends 135 miles north in Mississippi. Destin currently serves
as  the  primary  transfer  of  gas  flows  from  the  Barnett  and  Haynesville  shale  plays  to  Florida  markets  through  interconnections  with  major  interstate  pipelines.
Contracted  volumes  on  the  Destin  pipeline  are  based  on  life-of-field  dedication,  dedicated  volumes  over  a  given  period,  or  interruptible  volumes  as  capacity
permits.

Wilprise

We own a 25.3% non-operated interest in Wilprise, a FERC-regulated, approximately 30-mile NGL pipeline that originates at the Kenner Junction and terminates
in Sorrento, Louisiana, where volumes flow via pipeline to a Baton Rouge fractionator.

Tri-States

We own a 16.7% non-operated interest in Tri-States, a FERC-regulated, 161-mile NGL pipeline and sole form of transport to Louisiana-based fractionators for
NGLs produced at the Pascagoula plant served by Destin and other facilities.

Competition

The  midstream  business  is  very  competitive,  with  a  number  of  publicly  traded  and  private  equity  backed  entities  servicing  the  space  based  on  reputation,
commercial  terms,  reliability,  service  levels,  location,  available  capacity,  capital  expenditures  and  efficiencies.  Competition  is  often  the  greatest  in  geographic
areas experiencing robust drilling by producers and during periods of high commodity prices for natural gas, crude oil and/or NGLs. Competition is also increased
in those geographic areas where our commercial contracts with our customers are shorter term and therefore must be renegotiated on a more frequent basis. An
increase  in  competition  could  result  from  new  pipeline,  processing  facility,  or  storage  installations  or  expansions  of  existing  facilities.    Major  competitors  in
various  aspects  of  our  business  include  DCP  Midstream  LLC;  Energy  Transfer  Partners,  L.P.;  EnLink  NGL  Marketing,  L.P.;  Kinder  Morgan  Energy  Partners;
Enbridge Energy Partners, L.P.; Columbia Gulf Transmission Company; Enterprise Gas Processing, LLC; Gulf South Pipeline Company, LP; Southern Natural
Gas Company; Tennessee Gas Pipeline Company, LLC; Texas Eastern Pipeline; International-Matex Tank Terminals; LBC Tank Terminals; Royal Vopak; Stolt-
Nielsen Limited, Westway Terminals Company LLC, and Williams, among others.

Other Segment Information

For  additional  information  on  our  segments,  including  revenues  from  customers,  profit  or  loss  and  total  assets,  see  Management's  Discussion  and  Analysis  of
Financial Condition and Results of Operations , in  Part  II,  Item  7 of  this  Annual  Report  and  Note  23 -  Reportable Segments, in  Part  II,  Item  8 of  this  Annual
Report.

Safety and Maintenance

We are subject to regulation by the Pipeline and Hazardous Materials Safety Administration ("PHMSA") pursuant to the Natural Gas Pipeline Safety Act of 1968
("NGPSA"),  and  by  the  Pipeline  Safety  Improvement  Act  of  2002  ("PSIA"),  which  was  reauthorized  and  amended  by  the  Pipeline  Inspection,  Protection,
Enforcement and Safety Act of 2006. The NGPSA regulates safety requirements in the design, construction, operation and maintenance of gas pipeline facilities,
while  the  PSIA  establishes  mandatory  inspections  for  all  U.S.  crude  oil  and  natural  gas  transportation  pipelines  and  some  gathering  lines  in  high-consequence
areas. The PHMSA has developed regulations implementing the PSIA that require transportation pipeline operators to implement integrity management programs,
including more frequent inspections and other measures to ensure pipeline safety in "high-consequence areas," such as high population areas. The Pipeline Safety,
Regulatory Certainty, and Job Creation Act of 2011, which became law in January 2012, increases the penalties for safety violations, establishes additional safety
requirements  for  newly  constructed  pipelines  and  requires  studies  of  safety  issues  that  could  result  in  the  adoption  of  new  regulatory  requirements  for  existing
pipelines. The PHMSA issued a final rule applying safety regulations to certain rural low-stress hazardous liquid pipelines that were not covered previously by
some of its safety regulations. We believe that this rule does not apply to any of our pipelines. PHMSA issued, but has yet to publish, its final rule for hazardous
liquids  pipelines  on  January  13,  2017.  That  rule  extends  regulatory  reporting  requirements  to  all  liquid  gathering  lines,  requires  additional  event-driven  and
periodic inspections, requires use of leak detection systems on all hazardous liquid pipelines, modifies repair criteria, and requires certain pipelines to eventually
accommodate  inline  inspection  tools.  It  is  unclear  when  or  if  this  rule  will  go  into  effect  as,  on  January  20,  2017,  the  Trump  Administration  directed  that  all
regulations that had been sent to the Office of the Federal Register, but not yet published, be immediately withdrawn for further review. In March 2016, PHMSA
published a notice of proposed rulemaking regarding natural gas pipelines that would amend existing integrity management requirements, expand assessment and
repair requirements to pipelines in areas with medium population densities, and extend regulatory requirements to onshore gas gathering lines that are currently
exempt. While we cannot predict the outcome of these legislative or regulatory initiatives, such legislative and regulatory changes could have a material effect on
our operations, particularly by extending more stringent and comprehensive safety regulations (such as integrity

16

management  requirements)  to pipelines  not previously  subject  to such requirements.  While  we expect any legislative  or regulatory  changes  to allow us time  to
become compliant with new requirements, costs associated with compliance may have a material effect on our operations. We cannot predict with any certainty at
this time the terms of any new laws or rules or the costs of compliance associated with such requirements.

We regularly inspect our pipelines, and third parties assist us in interpreting the results of the inspections.

States  are  largely  preempted  by  federal  law  from  regulating  pipeline  safety  for  interstate  lines,  but  most  states  are  certified  by  the  U.S.  Department  of
Transportation  ("DOT")  to  assume  responsibility  for  enforcing  federal  intrastate  pipeline  regulations  and  inspection  of  intrastate  pipelines.  In  practice,  because
states  can  adopt  stricter  standards  for  intrastate  pipelines  than  those  imposed  by  the  federal  government  for  interstate  lines,  states  vary  considerably  in  their
authority and capacity to address pipeline safety. These state crude oil and gas standards may include requirements for facility design and management in addition
to requirements for pipelines. We do not anticipate any significant difficulty in complying with applicable state laws and regulations. Our natural gas pipelines
have continuous inspection and compliance programs designed to keep the facilities in compliance with pipeline safety and pollution control requirements.

In  addition,  we  are  subject  to  a  number  of  federal  and  state  laws  and  regulations,  including  the  federal  Occupational  Safety  and  Health  Act  ("OSHA"),  and
comparable state statutes, the purposes of which are to protect the health and safety of workers, both generally and within the pipeline industry. In addition, the
OSHA  hazard  communication  standard,  the  Environmental  Protection  Agency  ("EPA"),  community  right-to-know  regulations  under  Title  III  of  the  federal
Superfund Amendment and Reauthorization Act (Superfund") and comparable state statutes require that information be maintained concerning hazardous materials
used or produced in our operations and that such information be provided to employees, state and local government authorities, and citizens. We and the entities in
which we own an interest are also subject to OSHA Process Safety Management ("PSM") regulations, which are designed to prevent or minimize the consequences
of  catastrophic  releases  of  toxic,  reactive,  flammable  or  explosive  chemicals.  We  have  an  internal  program  of  inspection  designed  to  monitor  and  enforce
compliance with worker safety requirements. We believe that we are in material compliance with all applicable laws and regulations relating to worker health and
safety, Superfund and PSM.

We and the entities in which we own an interest are subject to:

•

•

EPA  Chemical  Accident  Prevention  Provisions,  also  known  as  the  Risk  Management  Plan  requirements,  which  are  designed  to  prevent  the  accidental
release of toxic, reactive, flammable or explosive materials; and
Department of Homeland Security Chemical Facility Anti-Terrorism Standards, which are designed to regulate the security of high-risk chemical facilities.

Regulation of Operations

Regulation of pipeline gathering and transportation services, natural gas sales and transportation of NGLs may affect certain aspects of our business and the market
for our products and services.

Regulation of our terminals require us to maintain and currently hold approvals and permits from federal, state and local regulatory agencies for air quality and
water discharge, as well as standard local occupational licenses.

Interstate Natural Gas Pipeline Regulation

Our interstate natural gas transportation systems are subject to the jurisdiction of FERC pursuant to the Natural Gas Act ("NGA"). Under the NGA, FERC has
authority  to  regulate  natural  gas  companies  that  provide  natural  gas  pipeline  transportation  services  in  interstate  commerce.  Federal  regulation  of  our  interstate
pipelines extends to such matters as:

rates, services, and terms and conditions of service;
the types of services offered to customers;
the certification and construction of new facilities;
the acquisition, extension, disposition or abandonment of facilities;
the maintenance of accounts and records;
relationships between affiliated companies involved in certain aspects of the natural gas business;
the initiation and discontinuation of services;

•
•
•
•
•
•
•
• market manipulation in connection with interstate sales, purchases or transportation of natural gas; and
•

participation by interstate pipelines in cash management arrangements.

17

Under the NGA, the rates for service on these interstate facilities must be just and reasonable and not unduly discriminatory.

The rates and terms and conditions for our interstate pipeline services are set forth in FERC-approved tariffs. Pursuant to FERC's jurisdiction over rates, existing
rates may be challenged by complaint and proposed rate increases may be challenged by protest. Any successful complaint or protest against our rates could have
an adverse impact on our revenue associated with providing transportation service.

In 2008, FERC issued Order No. 717, a final rule that implements standards of conduct that include three primary rules: (1) the "independent functioning rule,"
which requires transmission function and marketing function employees to operate independently of each other; (2) the "no-conduit rule," which prohibits passing
transmission  function  information  to  marketing  function  employees;  and  (3)  the  "transparency  rule,"  which  imposes  posting  requirements  to  help  detect  any
instances of undue preference. The FERC has since issued four rehearing orders that generally reaffirmed the determinations in Order No. 717 and also clarified
certain provisions of the Standards of Conduct.

In April 2008, the FERC issued a Policy Statement regarding the composition of proxy groups for determining the appropriate return on equity for natural gas and
crude oil pipelines  using FERC's Discounted Cash Flow ("DCF") model for setting cost-of-service  or recourse rates. In the policy statement, FERC concluded,
among other matters that Master Limited Partnerships ("MLPs") should be included in the proxy group used to determine return on equity for both natural gas and
crude oil pipelines, but the long-term growth component of the DCF model should be limited to fifty percent of long-term gross domestic product. The adjustment
to the long-term growth component, and all other things being equal, results in lower returns on equity than would be calculated without the adjustment. However,
the actual return on equity for our interstate pipelines will depend on the specific companies included in the proxy group and the specific conditions at the time of
the future rate case proceeding.

In July 2016, the D.C. Circuit issued its opinion in United Airlines, Inc., et al.v. FERC , finding that FERC had acted arbitrarily and capriciously when it failed to
demonstrate that permitting an interstate petroleum products pipeline organized as a limited partnership to include an income tax allowance in the cost of service
underlying its rates in addition to the discounted cash flow return on equity would not result in the pipeline partnership owners double-recovering their income
taxes. The court vacated FERC’s order and remanded to FERC to consider mechanisms for demonstrating that there is no double recovery as a result of the income
tax  allowance.  On  December  15,  2016,  FERC  issued  a  Notice  of  Inquiry  seeking  comment  on  how  to  address  any  double  recovery  resulting  from  income  tax
allowance policy. On March 15, 2018, FERC issued an order on remand in the United Airlines case and a revised policy statement on income tax recovery that
disallows income tax allowances for master limited partnerships in cost of service rates. In addition, FERC issued a notice of proposed rulemaking on March 15,
2018 that proposes to require all interstate natural gas pipelines to submit cost of service information to account for reductions in cost of service resulting from
FERC’s new policy on income tax allocations for master limited partnerships and the reduction in the corporate tax rate from the Tax Cuts and Jobs Act that went
into effect January 1, 2018. Depending upon the resolution of these issues, the cost of service rates of our interstate natural gas pipelines could be affected to the
extent they propose new rates or changes to their existing rates or if their rates are subject to complaint or challenged by FERC. However, we have considered the
impact the proposed policy changes by the FERC would have on us, and we have determined that based on the current rate structure on the Partnership's FERC
regulated pipelines, the proposed changes are expected to have a negligible impact on the earnings and cash flow of the Partnership. Although we cannot predict
whether FERC will propose any additional policy revisions, we expect any such policy revisions will have limited application to us, because a substantial majority
of the Partnership's operations are not FERC regulated.

Section 311 Pipelines

Intrastate  transportation  of  natural  gas  is  largely  regulated  by  the  state  in  which  such  transportation  takes  place.  To  the  extent  that  our  intrastate  natural  gas
transportation  systems  transport  natural  gas  in  interstate  commerce  without  an  exemption  under  the  NGA,  the  rates,  terms  and  conditions  of  such  services  are
subject  to  FERC  jurisdiction  under  Section  311  of  the  Natural  Gas  Policy  Act,  or  NGPA,  and  Part  284  of  the  FERC's  regulations.  Pipelines  providing
transportation service under Section 311 are required to provide services on an open and nondiscriminatory basis. The NGPA regulates, among other things, the
provision of transportation services by an intrastate natural gas pipeline on behalf of a local distribution company or an interstate natural gas pipeline. The rates,
terms and conditions of some transportation services provided on our Section 311 pipeline systems are subject to FERC regulation pursuant to Section 311 of the
NGPA. Under Section 311, rates charged for intrastate transportation must be fair and equitable, and amounts collected in excess of fair and equitable rates are
subject to refund with interest. The terms and conditions of service set forth in the intrastate facility's statement of operating conditions are also subject to FERC's
review and approval. Should the FERC determine not to authorize rates equal to or greater than our currently approved Section 311 rates, our business may be
adversely affected. Failure to observe the service limitations applicable to transportation and storage services under Section 311, failure to comply with the rates
approved by the FERC for Section 311 service, and failure to comply with the terms

18

and conditions of service established in the pipeline's FERC-approved statement of operating conditions could result in alteration of jurisdictional status, and/or the
imposition of administrative, civil and criminal remedies.

Hinshaw Pipelines

Intrastate natural gas pipelines are defined as pipelines that operate entirely within a single state, and generally are not subject to FERC's jurisdiction under the
NGA. Hinshaw pipelines, by definition, also operate within a single state, but can receive gas from outside their state without becoming subject to FERC's NGA
jurisdiction. Specifically, Section 1(c) of the NGA exempts from the FERC's NGA jurisdiction those pipelines that transport gas in interstate commerce if (1) they
receive  natural  gas  at  or  within  the  boundary  of  a  state,  (2)  all  the  gas  is  consumed  within  that  state  and  (3)  the  pipeline  is  regulated  by  a  state  commission.
Following the enactment of the NGPA, the FERC issued Order No. 63 authorizing Hinshaw pipelines to apply for authorization to transport natural gas in interstate
commerce in the same manner as intrastate pipelines operating pursuant to Section 311 of the NGPA. Hinshaw pipelines frequently operate pursuant to blanket
certificates to provide transportation and sales service under the FERC's regulations.

Historically, FERC did not require intrastate and Hinshaw pipelines to meet the same rigorous transactional reporting guidelines as interstate pipelines. However,
as discussed below, in 2010 the FERC issued Order No. 735, which increases FERC regulation of certain intrastate and Hinshaw pipelines. See Market Behavior
Rules; Posting and Reporting Requirements.

Gathering Pipeline Regulation

Section 1(b) of the NGA exempts natural gas gathering facilities from the jurisdiction of FERC. However, some of our natural gas gathering activity is subject to
Internet posting requirements imposed by FERC as a result of FERC's market transparency initiatives. We believe that our natural gas pipelines meet the traditional
tests that FERC has used to determine that a pipeline is a gathering pipeline and is, therefore, not subject to FERC jurisdiction. The distinction between FERC-
regulated transmission services and federally unregulated gathering services, however, is the subject of substantial, on-going litigation, so the classification and
regulation of our gathering facilities are subject to change based on future determinations by FERC, the courts or Congress. State regulation of gathering facilities
generally includes various safety, environmental and, in some circumstances, nondiscriminatory take requirements and complaint-based rate regulation. In recent
years, FERC's efforts to promote open access, transparency,  and the unbundling of interstate  pipeline services has prompted a number of interstate  pipelines to
transfer  their  non-jurisdictional  gathering  facilities  to  unregulated  affiliates.  As  a  result  of  these  activities,  natural  gas  gathering  may  begin  to  receive  greater
regulatory scrutiny at both the state and federal levels. Our natural gas gathering operations could be adversely affected should they be subject to more stringent
application  of  state  or  federal  regulation  of  rates  and  services.  Our  natural  gas  gathering  operations  also  may  be  or  become  subject  to  additional  safety  and
operational  regulations relating  to the design, installation,  testing, construction,  operation, replacement  and management  of gathering  facilities.  Additional rules
and legislation pertaining to these matters are considered or adopted from time to time. We cannot predict what effect, if any, such changes might have on our
operations, but the industry could be required to incur additional capital expenditures and increased costs depending on future legislative and regulatory changes.

Our natural gas gathering operations are subject to ratable take and common purchaser statutes in most of the states in which we operate. These statutes generally
require  our  gathering  pipelines  to  take  natural  gas  without  undue  discrimination  as  to  source  of  supply  or  producer.  These  statutes  are  designed  to  prohibit
discrimination in favor of one producer over another producer or one source of supply over another source of supply. The regulations under these statutes can have
the effect of imposing some restrictions on our ability as an owner of gathering facilities to decide with whom we contract to gather natural gas. The states in which
we operate have adopted a complaint-based regulation of natural gas gathering activities, which allows natural gas producers and shippers to file complaints with
state regulators in an effort to resolve grievances relating to gathering access and rate discrimination. We cannot predict whether such a complaint will be filed
against us in the future. Failure to comply with state regulations can result in the imposition of administrative, civil and criminal remedies. To date, there has been
no adverse effect to our system due to these regulations.

Market Behavior Rules; Posting and Reporting Requirements

On August 8, 2005, Congress enacted the Energy Policy Act of 2005, ("EP Act 2005"). Among other matters, the EP Act 2005 amended the NGA to add an anti-
manipulation provision that makes it unlawful for any entity to engage in prohibited behavior in contravention of rules and regulations to be prescribed by FERC
and,  furthermore,  provides  FERC  with  additional  civil  penalty  authority.  On  January  19,  2006,  FERC  issued  Order  No.  670,  a  rule  implementing  the  anti-
manipulation provision of the EP Act 2005, and subsequently denied rehearing. The rules make it unlawful for any entity, directly or indirectly in connection with
the  purchase  or  sale  of  natural  gas  subject  to  the  jurisdiction  of  FERC  or  the  purchase  or  sale  of  transportation  services  subject  to  the  jurisdiction  of  FERC  to
(1) use or employ any device, scheme or artifice to defraud; (2) to make any untrue statement of material

fact or omit to make any such statement necessary to make the statements made not misleading; or (3) to engage in any act or practice that operates as a fraud or
deceit upon any person. The new anti-manipulation rules apply to interstate gas pipelines and storage companies and intrastate gas pipelines and storage companies
that provide interstate services, such as Section 311 service, as well as otherwise non-jurisdictional entities to the extent the activities are conducted "in connection
with" gas sales, purchases or transportation subject to FERC jurisdiction. The new anti-manipulation rules do not apply to activities that relate only to intrastate or
other  non-jurisdictional  sales  or  gathering,  but  only  to  the  extent  such  transactions  do  not  have  a  "nexus"  to  jurisdictional  transactions.  The  EP  Act  2005  also
amends  the  NGA  and  the  NGPA  to  give  FERC  authority  to  impose  civil  penalties  for  violations  of  these  statutes,  up  to  $1,000,000  per  day  per  violation  for
violations  occurring  after  August  8,  2005.  This  maximum  penalty  authority  established  by  statute  will  continue  to  be  adjusted  periodically  for  inflation.  In
connection  with  this  enhanced  civil  penalty  authority,  FERC  issued  a  policy  statement  on  enforcement  to  provide  guidance  regarding  the  enforcement  of  the
statutes, orders, rules and regulations it administers, including factors to be considered in determining the appropriate enforcement action to be taken. Should we
fail to comply with all applicable FERC-administered statutes, rule, regulations and orders, we could be subject to substantial penalties and fines.

The EP Act of 2005 also added a section 23 to the NGA authorizing the FERC to facilitate price transparency in markets for the sale or transportation of physical
natural  gas  in  interstate  commerce.  In  2007,  FERC  took  steps  to  enhance  its  market  oversight  and  monitoring  of  the  natural  gas  industry  by  issuing  several
rulemaking orders designed to promote gas price transparency and to prevent market manipulation. In December 2007, FERC issued a final rule on the annual
natural  gas transaction  reporting  requirements,  as amended  by  subsequent  orders  on rehearing,  or  Order No. 704. Order  No. 704 requires  buyers  and sellers  of
annual quantities of natural gas of 2,200,000 MMBtu or more, including entities not otherwise subject to FERC jurisdiction, to submit on May 1 of each year an
annual report to FERC describing their aggregate volumes of natural gas purchased or sold at wholesale in the prior calendar year to the extent such transactions
utilize, contribute to or may contribute to the formation of price indices. Order No. 704 also requires market participants to indicate whether they report prices to
any index publishers and, if so, whether their reporting complies with FERC's policy statement on price reporting. In June 2010, the FERC issued the last of its
three orders on rehearing further clarifying its requirements.

In May 2010, the FERC issued Order No. 735, which requires intrastate pipelines providing transportation services under Section 311 of the NGPA and Hinshaw
pipelines operating under Section 1(c) of the NGA to report on a quarterly basis more detailed transportation and storage transaction information, including: rates
charged by the pipeline under each contract; receipt and delivery points and zones or segments covered by each contract; the quantity of natural gas the shipper is
entitled to transport, store, or deliver; the duration of the contract; and whether there is an affiliate relationship between the pipeline and the shipper. Order No. 735
further requires that such information must be supplied through a new electronic reporting system and will be posted on FERC's website, and that such quarterly
reports  may  not  contain  information  redacted  as  privileged.  The  FERC  promulgated  this  rule  after  determining  that  such  transactional  information  would  help
shippers make more informed purchasing decisions and would improve the ability of both shippers and the FERC to monitor actual transactions for evidence of
market power or undue discrimination. Order No. 735 also extends the FERC's periodic review of the rates charged by the subject pipelines from three years to five
years.  Order  No.  735  became  effective  on  April  1,  2011.  In  December  2010,  the  FERC  issued  Order  No.  735-A.  In  Order  No.  735-A,  the  FERC  generally
reaffirmed Order No. 735 requiring section 311 and "Hinshaw" pipelines to report on a quarterly basis storage and transportation transactions containing specific
information for each transaction, aggregated by contract.

In  July  2010,  for  the  first  time  the  FERC  issued  an  order  finding  that  the  prohibition  against  buy/sell  arrangements  applies  to  interstate  open  access  services
provided by Section 311 and Hinshaw pipelines. The FERC denied the numerous requests for rehearing of the July order. However, in October 2010, the FERC
issued a Notice of Inquiry seeking public comment on the issue of whether and how parties that hold firm capacity on some intrastate pipelines can allow others to
use their capacity, including to what extent buy/sell transactions should permitted and whether the FERC should consider requiring such pipelines to offer capacity
release programs. In the Notice of Inquiry, the FERC granted a blanket waiver regarding such transactions while the FERC is considering these policy issues. The
comment period has ended but the FERC has not yet issued an order.

Interstate Oil and Liquids Pipeline Regulation

Our Bakken crude oil gathering system, FERC-regulated American Panther, LLC offshore liquids pipelines (known as the Tiger Shoals and MP 77 offshore
pipeline systems) and the Tri-States and Wilprise NGL pipelines, in which we have equity investments, are regulated as common carrier interstate pipelines by the
FERC under the Interstate Commerce Act (“ICA”), the Energy Policy Act of 1992 (“EP Act 1992”) and the rules and regulations promulgated under those laws.
Under the ICA, FERC has authority regarding the rates and terms and conditions of service for the transportation of oil and natural gas liquids in interstate
commerce. Such pipelines are regulated as common carriers. FERC regulation is limited to rate-related issues, and does not extend to the construction of new
facilities or cessation of service. The ICA and FERC’s regulations require that rates and terms and conditions of service for interstate service on common carrier
pipelines be just and reasonable and must not be

20

unduly discriminatory or confer any undue preference upon any shipper. FERC’s regulations also require interstate common carrier pipelines to file with FERC
and publicly post tariffs stating their interstate transportation rates and terms and conditions of service.

In general, interstate common carrier pipeline rates are initially set through negotiations with non-affiliated shippers or via cost of service ratemaking. In addition,
rates can be set via settlement agreed to by all shippers and market-based rates may be permitted in certain circumstances. Effective January 1, 1995, the FERC
implemented regulations pursuant to EP Act 1992 establishing an indexing system that permits an oil pipeline, subject to limited challenges, to annually increase or
decrease its transportation rates due to inflationary changes in costs using a FERC-approved index, without making a cost of service filing. Every five years, the
FERC reviews the appropriateness of the index in relation to industry costs. On December 17, 2015, the FERC established a new Producer Price Index for Finished
Goods (the “PPI-FG”) of PPI-FG plus 1.23 percent for the five-year period beginning July 1, 2016. Under FERC’s regulations, pipelines can request a rate increase
that exceeds the rate obtained through application of the indexing methodology by using a cost-of-services approach, but only after the pipeline establishes that a
substantial divergence exists between the actual costs experienced by the pipeline and the rates resulting from application of the indexing methodology.

Under  the  ICA,  FERC  or  interested  persons  may  challenge  existing  or  proposed  new  or  changed  rates,  services,  or  terms  and  conditions  of  service.  FERC  is
authorized to investigate such charges and may suspend the effectiveness of a new rate for up to seven months. FERC could require a common carrier pipeline to
collect rates subject to refund until completion of an investigation during which FERC could find that the new or changed rate is unlawful. In contrast, FERC has
clarified that initial rates and terms of service agreed upon with committed shippers in a transportation services agreement are not subject to protest or a cost-of-
service analysis where the pipeline held an open season offering all potential shippers service on the same terms.

A successful rate challenge could result in a common carrier pipeline paying refunds of revenue collected in excess of the just and reasonable rate, together with
interest for the period the rate was in effect, if any. FERC may also order a pipeline to reduce its rates prospectively, and may require a common carrier pipeline to
pay shippers reparations retroactively for rate overages for a period of up to two years prior to the filing of a complaint. FERC also has the authority to change
terms and conditions of service if it determines that they are unjust or unreasonable or unduly discriminatory or preferential.

On March 15, 2018, FERC issued an order on remand in the United Airlines case and a revised policy statement on income tax recovery that disallows income tax
allowances for master limited partnerships in cost of service rates. Under the revised policy statement, pipelines can no longer include income tax allowances in
their annual FERC Form 6 report regarding their cost of service. In addition, FERC announced in the revised policy statement that it intends to account for its new
policy on income tax allowances for MLPs and the reduction in the corporate tax rate from the Tax Cuts and Jobs Act in its next five-year assessment of the oil
pipeline index in 2020. However, we have considered the impact the proposed policy changes by the FERC would have on us, and we have determined that based
on the current rate structure on the Partnership's FERC regulated pipelines, the proposed changes are expected to have a negligible impact on the earnings and cash
flow of the Partnership. Although we cannot predict whether FERC will propose any additional policy revisions, we expect any such policy revisions will have
limited application to us, because a substantial majority of the Partnership's operations are not FERC regulated.

Offshore Natural Gas Pipelines

Our  offshore  natural  gas  gathering  pipelines  are  subject  to  federal  regulation  under  the  Outer  Continental  Shelf  Lands  Act,  which  requires  that  all  pipelines
operating on or across the outer continental shelf provide open and nondiscriminatory access to shippers. From 1982 until 2012, the Minerals Management Service
("MMS"), of the U.S. Department of the Interior ("DOI"), was the federal agency that managed the nation's crude oil, natural gas, and other mineral resources on
the outer continental shelf, which is all submerged lands lying seaward of state coastal waters which are under U.S. jurisdiction, and collected, accounted for, and
disbursed  revenues  from  federal  offshore  mineral  leases.  On  June  18,  2010,  the  Minerals  Management  Service  was  renamed  the  Bureau  of  Ocean  Energy
Management, Regulation and Enforcement ("BOEMRE"). In October 2011, the BOEMRE was reorganized into and replaced by two separate agencies, the Bureau
of  Ocean  Energy  Management  ("BOEM")  and  the  Bureau  of  Safety  and  Environmental  Enforcement  ("BSEE").  The  BOEM  manages  the  exploration  and
development of the nation's offshore resources. BOEM seeks to appropriately balance economic development, energy independence, and environmental protection
through crude oil and gas leases, renewable energy development and environmental reviews and studies. BSEE works to promote safety, protect the environment,
and conserve resources offshore through vigorous regulatory oversight and enforcement.

Sales of Natural Gas and NGLs

The price at which we sell natural gas is not currently subject to federal rate regulation and, for the most part, is not subject to state regulation. However, with
regard to our physical sales of these energy commodities, we are required to observe anti-market

21

manipulation  laws  and  related  regulations  enforced  by  the  FERC  and/or  the  Commodity  Futures  Trading  Commission  ("CFTC"),  and  the  Federal  Trade
Commission  ("FTC").  Should  we  violate  the  anti-market  manipulation  laws  and  regulations,  we  could  also  be  subject  to  related  third-party  damage  claims  by,
among others, sellers, royalty owners and taxing authorities.

Sales of NGLs are not currently regulated and are made at negotiated prices. Nevertheless, Congress could enact price controls in the future.

As  discussed  above,  the  price  and  terms  of  access  to  pipeline  transportation  are  subject  to  extensive  federal  and  state  regulation.  The  FERC  is  continually
proposing and implementing new rules and regulations affecting interstate natural gas pipelines and those initiatives may also affect the intrastate transportation of
natural gas both directly and indirectly.

Environmental Matters

General

Our operation of pipelines, plants, terminals and other facilities for the gathering, compressing, treating and transporting of natural gas and other products is subject
to stringent and complex federal, state and local laws and regulations relating to the protection of the environment. As an owner or operator of these facilities, we
must comply with these laws and regulations at the federal, state and local levels. These laws and regulations can restrict or impact our business activities in many
ways, such as:

•
•
•
•
•

requiring the installation of pollution-control equipment or otherwise restricting the way we operate;
limiting or prohibiting construction activities in sensitive areas, such as wetlands, coastal regions or areas inhabited by endangered or threatened species;
delaying system modification or upgrades during permit reviews;
requiring investigatory and remedial actions to mitigate pollution conditions caused by our operations or attributable to former operations; and
enjoining the operations of facilities deemed to be in non-compliance with permits issued pursuant to such environmental laws and regulations.

Failure to comply with these laws and regulations may trigger a variety of administrative, civil and criminal enforcement measures, including the assessment of
monetary  penalties.  Certain  environmental  statutes  impose  strict  joint  and  several  liability  for  costs  required  to  clean  up  and  restore  sites  where  substances,
hydrocarbons or wastes have been disposed or otherwise released. 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.

The trend in environmental regulation is to place more restrictions and limitations on activities that may affect the environment, and thus, there can be no assurance
as to the amount or timing of future expenditures for environmental compliance or remediation and actual future expenditures may be different from the amounts
we currently anticipate. We try to anticipate future regulatory requirements that might be imposed and plan accordingly to remain in compliance with changing
environmental  laws  and  regulations  and  to  minimize  the  costs  of  such  compliance.  We  also  actively  participate  in  industry  groups  that  help  formulate
recommendations for addressing existing or future regulations.

We do not believe that compliance with federal, state or local environmental laws and regulations will have a material adverse effect on our business, financial
position or results of operations or cash flows. In addition, we believe that the various environmental activities in which we are presently engaged are not expected
to materially interrupt or diminish our operational ability to gather, compress, treat and transport natural gas. We cannot assure, however, that future events, such
as changes in existing laws or enforcement policies, the promulgation of new laws or regulations or the development or discovery of new facts or conditions will
not cause us to incur significant costs. Below is a discussion of the material environmental laws and regulations that relate to our business. We believe that we are
in substantial compliance with all of these environmental laws and regulations.

Hazardous Substances and Waste

Our operations are subject to environmental laws and regulations relating to the management and release of hazardous substances, solid and hazardous wastes and
petroleum  hydrocarbons.  These  laws  generally  regulate  the  generation,  storage,  treatment,  transportation  and  disposal  of  solid  and  hazardous  waste  and  may
impose strict joint and several liability for the investigation and remediation of affected areas where hazardous substances may have been released or disposed. For
instance, the Comprehensive Environmental Response, Compensation, and Liability Act ("CERCLA"), and comparable state laws impose liability, without regard
to fault or the legality of the original conduct, on certain classes of persons that contributed to the release of a hazardous

22

substance into the environment. These persons include the current or former owner or operator of the site where the release occurred, and anyone who disposed or
arranged  for  the  disposal  of  a  hazardous  substance  released  at  the  site.  We  may  handle  hazardous  substances  within  the  meaning  of  CERCLA, or  similar  state
statutes, in the course of our ordinary operations and, as a result, may be jointly and severally liable under CERCLA for all or part of the costs required to clean up
sites at which these hazardous substances have been released into the environment.

We also generate industrial wastes that are subject to the requirements of the Resource Conservation and Recovery Act ("RCRA"), and comparable state statutes.
While  RCRA  regulates  both  solid  and  hazardous  wastes,  it  imposes  strict  requirements  on  the  generation,  storage,  treatment,  transportation  and  disposal  of
hazardous  wastes.  We  generate  little  hazardous  waste;  however,  it  is  possible  that  these  wastes,  which  could  include  wastes  currently  generated  during  our
operations, will in the future be designated as "hazardous wastes" and, therefore, be subject to more rigorous and costly disposal requirements. In December 2016,
the  EPA  and  environmental  groups  entered  into  a  consent  decree  to  address  EPA’s  alleged  failure  to  timely  assess  its  RCRA  Subtitle  D  criteria  regulations
exempting certain exploration and production related oil and gas wastes from regulation as hazardous wastes under RCRA. The consent decree requires EPA to
propose a rulemaking by March 2019 for revision of certain Subtitle D criteria regulations pertaining to oil and gas wastes or to sign a determination that revision
of the regulations is not necessary. Any such changes in the laws and regulations could have a material adverse effect on our maintenance capital expenditures and
operating expenses.

We currently own or lease properties where hydrocarbons are being or have been handled for many years. Although previous operators have utilized operating and
disposal practices that were standard in the industry at the time, hydrocarbons or other wastes may have been disposed of or released on or under the properties
owned or leased by us or on or under the other locations where these hydrocarbons and wastes have been transported for treatment or disposal. These properties
and the wastes disposed thereon may be subject to CERCLA, RCRA and analogous state laws. Under these laws, we could be required to remove or remediate
previously disposed wastes (including wastes disposed of or released by prior owners or operators), to clean up contaminated property (including contaminated soil
and groundwater) or to perform remedial operations to prevent future contamination. We are not currently aware of any facts, events or conditions relating to such
requirements that could materially impact our operations or financial condition.

Air Quality and Climate Change

Our operations are subject to the federal Clean Air Act and comparable state and local laws and regulations. These laws and regulations regulate emissions of air
pollutants  from  various  industrial  sources,  including  our  compressor  stations  and  processing  plants,  and  also  impose  various  monitoring  and  reporting
requirements. Such laws and regulations may require that we obtain pre-approval for the construction or modification of certain projects or facilities expected to
produce  or  significantly  increase  air  emissions,  obtain  and  strictly  comply  with  air  permits  containing  various  emissions  and  operational  limitations  and  utilize
specific emission control technologies to limit emissions. Failure to comply with applicable air statutes or regulations may lead to the assessment of administrative,
civil  or  criminal  penalties  and  may  result  in  the  limitation  or  cessation  of  construction  or  operation  of  certain  air  emission  sources.  Although  we  can  give  no
assurances,  we  believe  such  requirements  will  not  have  a  material  adverse  effect  on  our  financial  condition  or  operating  results,  and  the  requirements  are  not
expected  to  be  more  burdensome  to  us  than  to  any  similarly  situated  company.  As  the  EPA  issues  new,  lower  National  Ambient  Air  Quality  Standards
("NAAQS"), we may be required to incur certain capital expenditures for air pollution control equipment in connection with obtaining and maintaining operating
permits  and  approvals  for  air  emissions.  For  example,  in  June  2010,  the  EPA  issued  a  new  NAAQS for  sulfur  dioxide,  or  SO  2, and replaced  the 24-hour and
annual standards with a more stringent hourly standard. In October 2015, the agency finalized a reduction of the national ambient air quality standard for ozone
standard from 75 parts per billion to 70 parts per billion; both nitrogen oxides and VOCs are ozone precursors. This reduction is expected to increase the number of
ozone nonattainment areas. In October 2016, the EPA also finalized Control Technology Guidelines for emissions of VOCs from crude oil and natural gas industry
sources to be relied  upon by states when implementing  the ozone standard in ozone nonattainment  areas. We believe  that our operations  will not be materially
adversely affected by such requirements, and the requirements are not expected to be any more burdensome to us than to any other similarly situated companies.

On April 17, 2012, the EPA approved final rules under the Clean Air Act that establish new air emission controls for crude oil and natural gas production, pipelines
and processing operations. These rules became effective on October 15, 2012. The established specific new requirements regarding emissions from wet seal and
reciprocating compressors at production facilities, gathering systems, boosting facilities and onshore natural gas processing plants, effective October 15, 2012, and
from pneumatic controllers and storage vessels at production facilities, gathering systems, boosting facilities and onshore natural gas processing plants, effective
October 15, 2013. In addition, the rules revise existing requirements for volatile organic compound (VOC) emissions from equipment leaks at onshore natural gas
processing  plants  by lowering  the  leak  definition  for  valves  from  10,000 parts  per million  to 500 parts  per million  and  requiring  the monitoring  of connectors,
pumps, pressure relief devices and open-ended lines, effective October 15, 2012. Initial compliance and ongoing compliance with the new subset of rules required
capital expenditures and

23

ongoing compliance expenses. Following the publication of the final rule, the EPA received petitions for reconsideration of certain aspects of the standards. On
April 12, 2013, the EPA published proposed updates to the NSPS Subpart OOOO storage tank requirements.  On September 23, 2013, the EPA published final
revisions  to  the  NSPS  Subpart  OOOO  storage  tank  requirements,  including  a  phase-in  of  installation  of  VOC  controls  and  alternate  limits  for  tanks  where
emissions have declined. The EPA issued revised definitions related to the stages of well completions and amended storage tank requirements under NSPS Section
OOOO in December 2014 and further revised the storage tank requirements in March 2015. More recently, in June 2016, the EPA published updates to new source
performance  standard  requirements  that  would  impose  more  stringent  controls  on  methane  and  VOC  emissions  from  oil  and  gas  development  and  production
operations, including hydraulic fracturing and other well completion activity. The EPA is currently engaged in rulemaking to stay the effective date of these rules.
Also,  the  EPA  published  NSPS  Subpart  0000a,  effective  August  2,  2016,  which  places  requirements  on  sources  constructed,  modified  or  reconstructed  after
September  18,  2015.  Many  of  the  requirements  of  NSPS  Subpart  OOOO  mirror  those  in  NSPS  Subpart  OOOO;  however,  new  equipment  being  regulated  are
pneumatic pumps and fugitive emissions at well sites and compressor stations. Similarly, in November 2016, the BLM issued rules requiring additional efforts by
producers to reduce venting, flaring, and leaking of natural gas produced on federal and Native American lands. However, in December 2017, implementation of
this rule was delayed until January 2019.

A number of states have adopted or considered programs to reduce “greenhouse gases,” or GHGs and the EPA has declared that GHGs “endanger” public health
and welfare, and is regulating GHG emissions from mobile sources such as cars and trucks. According to the EPA, this final action on the GHG vehicle emission
rule triggered regulation of carbon dioxide and other GHG emissions from stationary sources under certain Clean Air Act programs at both the federal and state
levels, particularly the Prevention of Significant Deterioration program and Title V permitting. These requirements for stationary sources took effect on January 2,
2011;  however,  in  June  2014  the  U.S.  Supreme  Court  reversed  a  D.C.  Circuit  Court  of  Appeals  decision  upholding  these  rules  and  struck  down  the  EPA’s
greenhouse gas permitting rules to the extent they impose a requirement to obtain a federal air permit based solely on emissions of greenhouse gases. Large sources
of other air pollutants, such as VOC or nitrogen oxides, could still be required to implement process or technology controls and obtain permits regarding emissions
of greenhouse gases. The EPA has also published various rules relating to the mandatory reporting of GHG emissions, including mandatory reporting requirements
of GHGs from petroleum and natural gas systems. In October 2015, the EPA amended and expanded greenhouse gas reporting requirements to all segments of the
crude oil and natural gas industry, including gathering and boosting facilities and blowdowns of natural gas transmission pipelines, starting with the 2016 reporting
year,  and  in  January  2016,  the  EPA  proposed  additional  revisions  to  leak  detection  methodology  to  align  the  reporting  rule  with  the  new  source  performance
standards.

The  permitting,  regulatory  compliance  and  reporting  programs  taken  as  a  whole  increase  the  costs  and  complexity  of  operating  oil  and  gas  operations  in
compliance with these legal requirements, with resulting potential to adversely affect our cost of doing business, demand for the oil and gas we transport and may
require us to incur certain capital expenditures in the future for air pollution control equipment in connection with obtaining and maintaining operating permits and
approvals for air emissions.

Water Discharges

The Federal Water Pollution Control Act ("Clean Water Act"), and analogous state laws impose restrictions and strict controls regarding the discharge of pollutants
into state waters as well as waters of the U.S. and to conduct construction activities in waters and wetlands. In May 2015, the EPA and the U.S. Army Corps of
Engineers  issued  a  final  rule  to  clarify  which  waters  and  wetlands  are  subject  to  Clean  Water  Act  regulation.  The  implementation  of  this  rule  was  stayed
nationwide in October 2015 as a result  of litigation.  In January 2018, the Supreme Court ruled that district courts have jurisdiction over challenges  to the rule.
Litigation surrounding this rule is ongoing, and, in addition to delaying the rule's applicability date until February 6, 2020, the EPA has instituted a rule-making
process to repeal  the rule. Certain  state regulations  and the general  permits issued under the Federal National Pollutant Discharge Elimination System program
prohibit  the  discharge  of  pollutants  and  chemicals.  Spill  Prevention  Control  and  Countermeasure  ("SPCC")  requirements  of  federal  laws  require  appropriate
containment berms and similar structures to help prevent the contamination of regulated waters in the event of a hydrocarbon tank spill, rupture or leak. In addition,
the Clean Water Act and analogous state laws require individual permits or coverage under general permits for discharges of storm water runoff from certain types
of  facilities.  These  permits  may  require  us  to  monitor  and  sample  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. Federal and state regulatory agencies can impose
administrative, civil and criminal penalties for non-compliance with discharge permits or other requirements of the Clean Water Act and analogous state laws and
regulations. We believe that compliance with existing permits and compliance with foreseeable new permit requirements will not have a material adverse effect on
our financial condition, results of operations or cash flow.

Safe Drinking Water Act

24

The underground injection of crude oil and natural gas wastes are regulated by the Underground Injection Control program authorized by the Safe Drinking Water
Act. The primary objective of injection well operating requirements is to ensure the mechanical integrity of the injection apparatus and to prevent migration of
fluids from the injection zone into underground sources of drinking water. As of December 31, 2017, the Partnership is in compliance with the requirements.

Endangered Species

The Endangered Species Act ("ESA") restricts activities that may affect endangered or threatened species or their habitats. While some of our pipelines may be
located in areas that are designated as habitats for endangered or threatened species, we believe that we are in substantial compliance with the ESA. However, the
designation of previously unidentified endangered or threatened species could cause us to incur additional costs or become subject to operating restrictions or bans
in the affected states.

National Environmental Policy Act

The National Environmental Policy Act ("NEPA") establishes a national environmental policy and goals for the protection, maintenance, and enhancement of the
environment  and  provides  a  process  for  implementing  these  goals  within  federal  agencies.  A  major  federal  agency  action  having  the  potential  to  significantly
impact the environment requires review under NEPA and, as a result, many activities requiring FERC approval must undergo NEPA review. Many of our activities
are  covered  under  categorical  exclusions  that  result  in  a  shorter  NEPA  review  process.  The  Council  on  Environmental  Quality  has  issued  final  guidance  to
reinvigorate NEPA reviews that, while intended to streamline the process, may result in longer review processes that could lead to delays and increased costs that
could materially adversely affect our revenues and results of operations.

Anti-terrorism Measures

The federal Department of Homeland Security regulates the security of chemical and industrial facilities pursuant to regulations known as the Chemical Facility
Anti-Terrorism  Standards. These regulations apply to oil and gas facilities,  among others, that are deemed to present “high levels of security risk.” Pursuant to
these  regulations,  certain  of  our  facilities  are  required  to  comply  with  certain  regulatory  provisions,  including  requirements  regarding  inspections,  audits,
recordkeeping, and protection of chemical-terrorism vulnerability information. 

Title to Properties and Rights-of-Way

Our real property falls into two categories: i) parcels that we own in fee and ii) parcels in which our interest derives from leases, easements, rights-of-way, permits
or licenses from landowners or governmental authorities, permitting the use of such land for our operations. Portions of the land on which our plants and other
major facilities are located are owned by us in fee title, and we believe that we have satisfactory title to these lands. The remaining land on which our plant sites
and major facilities are located, are held by us pursuant to surface leases between us, as lessee, and the fee owner of the lands, as lessors. Our predecessors leased
or owned these lands for many years without any material challenge known to us relating to the title to the land upon which the assets are located, and we believe
that we have satisfactory leasehold estates or fee ownership in such lands. We have no knowledge of any challenge to the underlying fee title of any material lease,
easement,  right-of-way,  permit  or license  held  by us  or  to our  title  to  any  material  lease,  easement,  right-of-way,  permit  or  lease,  and  we believe  that  we have
satisfactory title to all of our material leases, easements, rights-of-way, permits and licenses.

Employees

The Partnership does not have any employees. All of the employees required to conduct and support our operations are employed by our General Partner, and the
officers  of  our  General  Partner  manage  our  operations  and  activities.  As  of  December  31,  2017,  our  General  Partner  employed  approximately  490  people  who
provide direct, full-time support to our operations. None of these employees are covered by collective bargaining agreements, and our General Partner considers its
employee relations to be positive.

General

We make certain filings, and amendments thereto, with the Securities and Exchange Commission (the "SEC"), including our annual report on Form 10-K, quarterly

Item 1A. Risk Factors

Limited partner interests are inherently different from capital stock of a corporation, although many of the business risks to which we are subject are similar
to those that would be faced by a corporation engaged in similar businesses. We urge you to carefully consider the following risk factors together with all of the
other information included in this Annual Report in evaluating an investment in our common units.

If any of the following risks were to occur, our business, financial condition, results of operations or cash flows could be materially adversely affected. In that
case, we might not be able to pay the minimum quarterly distribution on our common units, the trading price of our common units could decline and you could lose
all or part of your investment in us.

The risks described below are not the only ones that we face. Additional risks not presently known to us or that we currently deem immaterial individually or
in the aggregate may also impair our business operations. This Annual Report also contains forward-looking statements that involve risks and uncertainties. Our
actual results could differ materially from those anticipated in these forward-looking statements as a result of various factors, including the risks and uncertainties
faced by us described below.

Risks Related to our Business

Our current and future indebtedness levels may limit our flexibility in obtaining additional financing and in pursuing other business opportunities.

As of December 31, 2017, we had approximately $1.2 billion in principal amount of debt outstanding (including approximately $697.9 million of borrowings

outstanding under our revolving credit facility). Our level of indebtedness could have important consequences to us, including the following:

•

•

•

•

•

our ability to obtain additional financing, if necessary, for working capital, capital expenditures, acquisitions or other purposes may be impaired or
such financing may not be available on favorable terms;
covenants contained in our existing and future credit and debt arrangements will require us to meet financial tests that may affect our flexibility in
planning for and reacting to changes in our business, including possible acquisition opportunities;
our  funds  available  for  operations,  future  business  opportunities  and  distributions  to  unitholders  will  be  reduced  by  that  portion  of  our  cash  flow
required to make principal and interest payments on our indebtedness;
our indebtedness level may make us more vulnerable than our competitors with less debt to competitive pressures or a downturn in our business or
the economy generally; and
our flexibility in responding to changing business and economic conditions may be limited.

Any of these factors could result in a material adverse effect on our business, financial condition, results of operations, business prospects and ability to make

cash distributions to our unitholders.

Our  ability  to  service  our  indebtedness  will  depend  upon,  among  other  things,  our  future  financial  and  operating  performance,  which  will  be  affected  by
prevailing  economic  conditions  and  financial,  business,  regulatory  and  other  factors,  some  of  which  are  beyond  our  control.  If  our  operating  results  are  not
sufficient to service our current or future indebtedness, we will be forced to take actions such as reducing distributions to our unitholders, reducing or delaying our
business  activities,  acquisitions,  investments  or  capital  expenditures,  selling  assets,  restructuring  or  refinancing  our  indebtedness,  or  seeking  additional  equity
capital or bankruptcy protection. We may not be able to effect any of these remedies on satisfactory terms, or at all.

We have identified material weaknesses in our internal controls for 2017 and have been unable to remediate the material weakness identified in 2016. If we
fail to remediate these material weaknesses or otherwise fail to develop, implement and maintain appropriate internal controls in future periods, our ability to
report our financial condition and results of operations accurately and on a timely basis could be adversely affected.

At  December  31,  2016,  we  identified  a  material  weakness  in  our  internal  controls  over  the  level  of  accounting  knowledge,  expertise  and  training
commensurate with our financial reporting requirements. This material weakness was not remediated at December 31, 2017. At December 31, 2017, we did not
maintain  an  effective  control  environment  as  we  lacked  sufficient  oversight  of  activities  related  to  our  internal  control  over  financial  reporting  and  had  an
insufficient complement of resources with an

26

appropriate level of accounting knowledge, expertise and training commensurate with our financial reporting requirements. This material weakness contributed to
additional  material  weaknesses,  as  the  Partnership  did  not  design  and  maintain  effective  controls  over:  verifying  that  complex,  non-routine  transactions  were
recorded appropriately; all financial statement assertions of revenues and receivables, specifically the review of the accounting for certain contracts, the review that
price, volume and other key contractual terms used to record revenue are consistent with the terms of the arrangement and the review that revenue is recorded in
the proper period; all financial statement assertions related to acquisitions and divestitures, specifically verifying the existence, rights and obligations associated
with  assets  acquired  and  liabilities  assumed,  reviewing  the  valuation  of  the  purchase  price  allocation  and  reviewing  the  completeness  and  accuracy  of  related
disclosures;  the  period-end  financial  reporting  process,  specifically  the  review  of  account  reconciliations  and  financial  statement  analyses  to  support  the
completeness and accuracy of the consolidated financial statements and disclosures; and the accuracy and valuation of asset retirement obligations, goodwill, other
intangible assets and finite-lived assets, specifically the review of the model, data, assumptions and calculations used in determining the estimated asset retirement
obligation and in impairment tests, and the related identification of changes in events and circumstances that indicate it is more likely than not that an impairment
indicator has occurred. Additionally, we did not maintain effective controls over certain information technology ("IT") general controls for a significant application
used in the preparation of our financial statements. Specifically, we did not maintain user access controls to ensure appropriate segregation of duties and adequate
restriction of user and privileged access to the financial application, programs, and data to appropriate Partnership personnel. These IT deficiencies did not result in
a  material  misstatement  to  the  financial  statements,  however,  the  deficiencies,  when  aggregated,  could  impact  our  ability  to  maintain  effective  segregation  of
duties,  as  well  as  maintain  effective  IT-dependent  controls  which  could  result  in  misstatements  of  substantially  all  of  the  financial  statement  accounts  and
disclosures  resulting  in  a  material  misstatement  to  the  annual  or  interim  consolidated  financial  statements  that  otherwise  would  not  be  prevented  or  detected.
Accordingly, our management determined that, as of December 31, 2017, our disclosure controls and procedures and our internal control over financial reporting
were  not  effective.  The  specific  material  weaknesses  and  our  remediation  efforts  are  described  in  Item  9A,  Controls  and  Procedures  of  this  Annual  Report.  A
“material weakness” is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a
material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis. We were not able to remediate material
weaknesses identified at December 31, 2016 during 2017, and we cannot assure you that we will adequately remediate the material weaknesses or that additional
material weaknesses in our internal controls will not be identified in the future.

We are in the process of remediating the identified material weaknesses in our internal controls, but we are unable at this time to estimate when the remediation
effort will be completed. During the course of implementing additional processes and controls, as well as controls operating effectiveness testing, we may identify
additional  control  deficiencies,  which  could  give  rise  to  other  material  weaknesses,  in  addition  to  the  material  weaknesses  described  above.  As  we  continue  to
evaluate and work to improve our internal control over financial reporting, we may determine to take additional measures to address these material weaknesses or
modify certain of the remediation measures. Further and continued determinations that there are material weaknesses in the effectiveness of our internal controls
could reduce our ability to obtain financing or could increase the cost of any financing we obtain and require additional expenditures of resources to comply with
applicable requirements.

The indenture governing our senior notes and our credit facility contain certain financial covenants and ratios and other restrictions. We may have difficulty
maintaining compliance with such financial covenants and ratios and other restrictions, which could adversely affect our business, financial condition, results
of operations and ability to pay distributions to our unitholders.

We are dependent upon certain earnings and cash flow generated by our operations in order to meet our debt service obligations. We also depend on our credit
facility for working capital and future expansion capital needs and, as necessary, to fund a portion of cash distributions to unitholders. The indenture governing the
notes  and  our  revolving  credit  facility  contain,  and  any  future  financing  agreements  may  contain,  operating  and  financial  restrictions  and  covenants  that  could
restrict  our  ability  to  finance  future  operations  or  capital  needs,  or  to  expand  or  pursue  our  business  activities,  which  may,  in  turn,  limit  our  ability  to  pay
distributions to our unitholders. For example, our revolving credit facility limits our ability to, among other things:

•
incur or guarantee additional indebtedness;
• make certain investments and acquisitions;
redeem or repay other debt or make other restricted payments;
•
enter into certain types of transactions with affiliates;
•
enter into agreements that restrict distributions or other payments from our restricted subsidiaries to us;
•
•
enter into sale and leaseback transactions;
• merge or consolidate with another company;
•
•

transfer, sell or otherwise dispose of assets, including equity interests in our subsidiaries;
cancel or modify material contracts;

27

Our  Second  Amended  and  Restated  Credit  Agreement  (the  “Credit  Agreement”)  contains  certain  financial  covenants,  including  (i)  a  consolidated  total
leverage ratio that requires our indebtedness not to exceed 5.00 times adjusted consolidated EBITDA (except during a specified acquisition period, as determined
under the terms of the Credit Agreement, at which time such ratio is increased to 5.50 times adjusted consolidated EBITDA), (ii) a consolidated secured leverage
ratio that requires our secured indebtedness not to exceed 3.50 times adjusted consolidated EBITDA, and (iii) a minimum interest coverage ratio that requires our
adjusted consolidated EBITDA to exceed consolidated interest charges by not less than 2.50 times. The financial covenants in our Credit Agreement may limit the
amount available to us for borrowing to less than $900.0 million. As of December 31, 2017, our consolidated total leverage ratio was 5.23 , our secured leverage
ratio was 3.29 and our interest coverage ratio was 3.62 , which were in compliance with the financial covenants. Our ability to comply with these covenants and
ratios in the future is uncertain and will be affected by the levels of cash flow from our operations and events or circumstances beyond our control, including events
and circumstances that may stem from the condition of the financial markets and commodity price levels.

We may not have sufficient cash from operations to enable us to pay distributions to holders of our common units.

We may not have sufficient available cash from operations each quarter to enable us to pay the minimum quarterly distribution of $0.4125 per common unit or
at all. These distributions may only be made from cash available for distribution after the preferred quarterly distribution to which our convertible preferred units
are entitled, the establishment of cash reserves, and payment of our fees and expenses. The amount of cash we can distribute on our units principally depends upon
the amount of cash we generate from our operations, which will fluctuate from quarter to quarter based on, among other things:

•

•
•
•
•
•
•

the  volume  of  natural  gas  we  and  our  joint  ventures  gather,  process  and  transport,  and  related  revenues  earned  under  our  and  our  joint  ventures’
transportation contracts;
the level of production of crude oil and natural gas and the resultant market prices of crude oil and natural gas and NGLs;
realized pricing impacts on our revenue and expenses that are directly subject to commodity price exposure;
capacity charges and volumetric fees associated with our transportation services;
the level of competition from other midstream energy companies in our geographic markets;
the level of our operating, maintenance and corporate costs; and
regulatory  action  affecting  the  supply  of,  or  demand  for,  natural  gas,  the  transportation  rates  we  can  charge  on  our  regulated  pipelines,  how  we
contract for services, our existing contracts, our operating costs and our operating flexibility.

In addition, the actual amount of cash we will have available for distribution will depend on other factors, including:

•
•
•
•
•
•
•
•

the level and timing of capital expenditures we make;
the cost of acquisitions, and the resulting costs of integrations, if any;
our debt service payments and requirements and other liabilities;
fluctuations in our working capital needs;
our ability to borrow funds and access capital markets;
restrictions contained in our Credit Agreement;
the amount of cash reserves established by our General Partner; and
other business risks affecting our cash levels.

There is no guarantee that unitholders will receive quarterly distributions from us. Our distributions are determined each quarter by the Board of Directors of
our General Partner based on the board’s consideration of the foregoing factors, our financial position, earnings, cash flow, current and future business needs and
other relevant factors at that time. We may reduce or eliminate distributions at any time we have insufficient cash available for distributions. This may be due to
insufficient  cash  reserves,  requirements  to  fund  current  or  anticipated  future  operations,  capital  expenditures,  acquisitions,  growth  or  expansion  projects,  debt
repayment or other business needs.

The amount of cash we have available for distribution depends primarily upon our cash flow and not solely on profitability, which will be affected by non-cash
items. As a result, we may make cash distributions during periods when we record net losses for financial reporting purposes and may not make cash distributions
during periods when we record net income for financial reporting purposes.

Any decrease in the volumes of natural gas, NGLs or crude oil that we or our joint ventures gather, process or transport could adversely affect our business
and operating results.

28

The  volumes  that  support  our  business  are  dependent  on  the  level  of  production  from  natural  gas  and  crude  oil  wells  connected  to  our  systems,  including
volumes  from  significant  customers,  the  production  of  which  will  naturally  decline  over  time.  As a  result,  our  cash  flows  associated  with  these  wells  will  also
decline over time. In order to maintain or increase throughput levels on our systems, we must obtain new sources of natural gas and crude oil. The primary factors
affecting our ability to obtain non-dedicated sources of natural gas and crude oil include (i) the level of successful drilling activity in our areas of operation and (ii)
our ability to compete for volumes from successful new wells.

We have no control over the level of drilling activity in our areas of operation, the amount of reserves associated with wells connected to our systems or the
rate at which production from a well declines. In addition, we have no control over producers or their drilling or production, which are affected by, among other
things:

•
•
•
•
•
•
•
•

prevailing and projected natural gas, crude oil and NGL prices;
the availability and cost of capital;
demand for natural gas, crude oil and NGLs;
levels of reserves;
geological considerations;
environmental or other governmental regulations, including the availability of drilling permits;
the absence of operational issues that curtail production; and
the availability of drilling rigs and other production and development costs.

Sustained reductions in exploration or production activity in our areas of operation would lead to reduced utilization of our assets. We are unable to predict
future potential movements in the market price for natural gas, crude oil and NGLs and thus, cannot predict the ultimate impact of prices on our operations. If
commodity prices decreased or if producers experienced sustained curtailment of production, this could lead to reduced profitability and may impact our liquidity
and compliance with financial covenants in our revolving credit facility. Reduced profitability may also result in future non-cash impairments of long-lived assets,
goodwill, or intangible assets.

Because of these and other factors, even if new natural gas, NGL and crude oil reserves are known to exist in areas served by our assets, producers may choose
not to develop those reserves. If reductions in drilling activity result in our inability to maintain the current levels of throughput on our systems, it could reduce our
revenue and cash flow and adversely affect our ability to make cash distributions to our unitholders.

Natural gas, crude oil, NGL and other commodity prices are volatile, and a reduction in these prices in absolute terms, or an adverse change in the prices of
natural gas and NGLs relative to one another, could adversely affect our net income, gross margin and cash flow and our ability to make distributions to our
unitholders.

We are subject to risks due to frequent and often substantial fluctuations in commodity prices. In the past, the prices of natural gas and crude oil have been
extremely volatile, and we expect this volatility to continue. Natural gas and crude oil prices declined dramatically in late 2015 and have fluctuated throughout
2016 and 2017. These factors include the supply of and demand for these commodities, which fluctuate with changes in market and economic conditions and other
factors, including:

•
•
•
•
•
•
•
•

worldwide economic conditions and political events, including actions taken by foreign oil and gas producing nations
worldwide weather events and conditions, including natural disasters and seasonal changes;
the levels of world-wide and domestic production and consumer demand;
the availability of imported, or market for exported, crude oil and liquefied natural gas, or LNG;
the availability of transportation systems with adequate capacity;
the volatility and uncertainty of regional pricing differentials;
the nature and extent of governmental regulation and taxation; and
the current and anticipated future prices of natural gas, crude oil, NGLs and other commodities.

Our growth strategy, and ability to fund expansion capital projects, requires access to new capital. Our ability to access the capital markets, tightened capital
markets or other factors that increase our cost of capital, or limit our access to capital, could impair our ability to grow.

We continuously consider potential  acquisitions  and opportunities  for expansion capital  projects.  Acquisition opportunities  arise  quickly and unexpectedly,
may occur at any time and may be significant in size relative to our existing assets and operations. Our ability to fund our capital projects and make acquisitions
depends on whether we can access the necessary financing to fund these activities. The delayed filing of this Annual Report has made us currently ineligible to use
a registration statement on Form S-3 to register the offer and sale of securities, which could increase the expense of accessing the capital markets. Any limitations

29

on our access to capital or increase in the cost of that capital could significantly impair our growth strategy. Our ability to maintain our targeted credit profile,
including  our  target  debt-to-equity  ratio,  could  affect  our  cost  of  capital  as  well  as  our  ability  to  execute  our  growth  strategy.  In  addition,  a  variety  of  factors
beyond our control could impact the availability or cost of capital, including domestic or international economic conditions, increases in key benchmark interest
rates or credit spreads, the adoption of new or amended banking or capital market laws or regulations, the re-pricing of market risks and volatility in capital and
financial markets.

Due to these factors, we cannot be certain that funding for our capital needs will be available from bank credit arrangements, our revolving credit facility or
capital  markets  on  acceptable  terms.  If  funding  is  not  available  when  needed,  or  is  available  only  on  unfavorable  terms,  we  may  be  unable  to  implement  our
development  plans,  enhance  our  existing  business,  complete  acquisitions  and  construction  projects,  take  advantage  of  business  opportunities  or  respond  to
competitive pressures, any of which could have a material adverse effect on our revenues and results of operations.

Our business is subject to a number of weather related risks, including severe weather in the U.S. Gulf of Mexico, which can cause significant damage and
disruption to our business interests located in that region.

The U.S. Gulf of Mexico experiences hurricanes and other extreme weather conditions on a frequent basis, the frequency of which may increase with climate
change. Our High Point system, our Offshore Texas system, our Destin system, our Okeanos system, our MPOG system and non-operated interests Delta House
and any future systems that we acquire in the U.S. Gulf of Mexico, are susceptible to adverse weather conditions in the U.S. Gulf of Mexico, including hurricanes
and other extreme weather conditions. Our insurance and weather derivatives may not cover all associated loss. High winds, storm surge, and turbulent seas can
cause significant damage and curtail these operations for extended periods during and after such weather conditions, which may result in decreased revenues from
our interests in these operations. In addition, these adverse weather conditions in the U.S. Gulf of Mexico can affect producers connected to our facilities even if
our facilities are not damaged, which may result in decreased revenues from our interests in these operations.

To the extent weather conditions are affected by climate change, customers’ energy use could increase or decrease depending on the duration and magnitude

of the changes, leading either to increased investment or decreased revenues.

We are subject to the risk of loss resulting from nonpayment or nonperformance by our customers and counterparties in the ordinary course of our business.

We are subject to the risk of loss resulting from nonpayment or nonperformance by our customers and counterparties in the ordinary course of our business.
Generally,  we  either  consider  our  customers  creditworthy  or  require  those  who  are  not  creditworthy  to  make  prepayments  or  provide  security  to  satisfy  credit
concerns.  However,  our  credit  procedures  and  policies  will  not  completely  eliminate  customer  and  counterparty  credit  risk.  Our  customers  and  counterparties
include entities whose creditworthiness may be suddenly and disparately impacted by, among other factors, commodity price volatility, deteriorating energy market
conditions, and public and regulatory opposition to energy producing activities.

In addition, in connection with the acquisition of certain of our assets, we have entered into agreements pursuant to which various counterparties have agreed

to indemnify us, subject to certain limitations, for certain matters arising from the pre-closing ownership and operation of assets.

The low commodity price environment in prior years negatively impacted many oil and gas companies causing them significant economic stress including, in
some cases, to file for bankruptcy protection or to renegotiate contracts, and this could recur. To the extent one or more of our key customers or counterparties
commences  bankruptcy  proceedings,  our contracts  with  such customers  or counterparties  may  be subject  to rejection  under  applicable  provisions  of the  United
States Bankruptcy Code or may be renegotiated. Further, during any such bankruptcy proceeding, prior to assumption, rejection or renegotiation of such contracts,
the bankruptcy court may temporarily authorize the payment of value for our services less than contractually required, which could have a material adverse effect
on our business, results of operations, cash flows and financial conditions. If we fail to adequately assess the creditworthiness of existing or future customers and
counterparties  or  otherwise  do  not  take  or  are  unable  to  take  sufficient  mitigating  actions,  including  obtaining  sufficient  collateral,  deterioration  in  their
creditworthiness and any resulting increase in nonpayment or nonperformance by them could cause us to write down or write off accounts receivable. Such write-
downs or write-offs could negatively affect our operating results in the periods in which they occur, and, if significant, could have a material adverse effect on our
business, results of operations, cash flows and financial condition.

30

If third-party pipelines or other midstream facilities interconnected to our gathering or transportation systems become partially or fully unavailable, or if the
volumes we gather or transport do not meet the natural gas quality requirements of such pipelines or facilities, our revenue and cash available for distribution
could be adversely affected.

Our natural gas gathering and processing and transportation systems connect to other pipelines or facilities, the majority of which are owned and operated by
third parties. The continuing operation of such third-party pipelines and other midstream facilities is not within our control. These pipelines and other midstream
facilities  and  others  upon  which  we  rely  may  become  unavailable  because  of  testing,  turnarounds,  line  repair,  reduced  operating  pressure,  lack  of  operating
capacity,  regulatory  requirements,  curtailments  of  receipt  or  deliveries  due  to  insufficient  capacity  or  because  of  damage  from  hurricanes  or  other  operational
hazards. For example, the explosion and fire at the Pascagoula Gas plant in June of 2016 suspended operations from that facility for over eight months. If any of
these pipelines or other midstream facilities becomes unable to receive or transport natural gas, or if the volumes we gather or transport do not meet the natural gas
quality requirements of such pipelines or facilities, our revenue and cash available for distribution may be adversely affected.

The adoption and implementation of new statutory and regulatory requirements for swap transactions could have an adverse impact on our ability to hedge
risks associated with our business.

Congress adopted the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) in 2010. Among other things, the Dodd-Frank
Act mandated significant changes to the over-the-counter derivative market and requires the Commodities Futures Trading Commission (the “CFTC”), the SEC
and other regulators to promulgate rules and regulations establishing federal oversight and regulation of the over-the-counter  derivative market. Although as of
December 31, 2017, the rules and regulations under the Dodd-Frank Act have not had an adverse effect on our ability to use certain derivative instruments, such
rules and regulations may have an adverse effect on our ability to do so in the future.

The rulemaking process under the Dodd-Frank Act has not been fully completed. As a result, the full impact of the Dodd-Frank Act and related regulatory
requirements  upon  our  business  will  not  be  known  until  the  regulations  are  implemented  and  the  market  for  derivatives  contracts  has  adjusted.  When  fully
implemented, the Dodd-Frank Act and any new regulations could increase the operational and transactional cost of derivatives contracts, reduce the availability of
derivatives to protect against risks we encounter, reduce our ability to monetize and restructure our existing derivatives contracts, impact commodity prices and
affect  the  number  or  creditworthiness  of  available  counterparties.  For  example,  the  rules  and  regulations  under  the  Dodd-Frank  Act  may  increase  the  costs  of
certain derivative products as a result of the imposition of capital, margin, clearing and exchange-trading requirements either on us or on our counterparties. Any
requirement to post more collateral to our counterparties in excess of what we currently post to collateralize our obligations may have a negative impact upon our
liquidity. Further, the CFTC has proposed rules that would place position limits on certain core futures contracts and equivalent swap contracts for or linked to
certain physical commodities, subject to certain exceptions which, if finalized, could further restrict our ability to utilize these products. If, as a result of the Dodd-
Frank Act and the rules and regulations promulgated thereunder, we reduce our use of certain derivatives, 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 or increase our distributions.

We do not control certain of the entities that own our projects and we may acquire future projects that we do not control.

We own a 50% membership interest in Cayenne, 35.7% of the Class A units of Delta House FPS LLC and Delta House Oil and Gas Lateral LLC, a 25.3%
membership interest in Wilprise, and a 16.7% membership interest in Tri-States. We do not control these projects or joint ventures or their governing boards. As a
result, our ability to pay cash distributions to our unitholders will depend in part on factors beyond our control, such as the performance of these projects or joint
ventures and their distributions of cash to us. Cash distributions to us may be reduced or suspended if the assets comprising the businesses of these projects or joint
ventures, or the assets of their customers, are adversely impacted by operational hazards.

Further, additional projects we may acquire may be subject to a similar structure where we do not own a majority of the project or project entity and we may
invest in joint ventures in which we share control or in which we are a minority investor. In these instances, the majority investor or controlling investor may not
have the level of experience, technical expertise, human resources management and other attributes necessary to operate these assets optimally.

A decrease in demand for natural gas, NGLs or condensate by the petrochemical, refining or heating industries, could adversely affect the profitability of our
midstream business.

Various  factors  impact  the  demand  for  natural  gas,  NGLs  and  condensate,  including  general  economic  conditions,  extended  periods  of  ethane  rejection,
increased  competition  from  petroleum-based  products  due  to  pricing  differences,  adverse  weather  conditions,  availability  of  natural  gas  processing  and
transportation capacity and government regulations affecting prices and

31

production levels of natural gas, NGLs and condensate. In addition, certain of our operating costs and expenses are fixed and do not vary with the volumes we
transport or redeliver. These costs and expenses may not decrease ratably or at all should we experience a reduction in the volumes we sell, transport or redeliver.
As a result, a decrease in demand for natural gas, NGLs or condensate by the petrochemical, refining or heating industries, could decrease volumes and adversely
affect the margin and profitability of our midstream business.

We depend on a relatively small number of customers for a significant portion of our gross margin. The loss of any one of these customers could adversely
affect our ability to make distributions.         

A  significant  percentage  of  the  gross  margin  in  each  of  our  segments  is  attributable  to  a  relatively  small  number  of  customers.  Additionally,  a  number  of
customers upon which our business depends are small companies that may have limited access to capital or that may, as a result of operational incidents or other
events, be disproportionately affected as compared to larger, better capitalized companies. Although we have gathering, processing and transmission contracts with
significant customers of varying duration and commercial terms, if one or more of these customers were to default on their contract or if we were unable to renew
our contract with one or more of these customers on favorable terms, we may not be able to replace these customers in a timely fashion, on favorable terms or at
all. In any of these situations, our gross margin and cash flows and our ability to make cash distributions to our unitholders may be adversely affected. We expect
our exposure to concentrated risk of non-payment or non-performance to continue as long as we remain substantially dependent on a relatively small number of
customers for a substantial portion of our gross margin.

Our industry is highly competitive and increased competitive pressure could adversely affect our business and operating results.

We compete with other midstream companies in our areas of operation. In addition, some of our competitors are large companies that have greater financial,
managerial and other resources than we do. Our competitors may expand or construct gathering, compression, treating, processing, transportation or terminaling
systems  that  would  create  additional  competition  for  the  services  we  provide  to  our  customers.  In  addition,  our  customers  may  develop  their  own  gathering,
compression,  treating,  processing  or  transportation  systems  in  lieu  of  using  ours.  Our  ability  to  renew  or  replace  existing  contracts  with  our  customers  at  rates
sufficient to maintain current revenue and cash flow could be adversely affected by the activities of our competitors and our customers. All of these competitive
pressures could have a material adverse effect on our business, results of operations, financial condition and ability to make cash distributions to our unitholders.

Our gathering, processing, transportation and terminal contracts subject us to renewal risks.

We gather, purchase, process, transport and sell most of the commodities on our systems under contracts with terms of various durations, including contracts
that have terms as short as one month or which are cancellable on as little as 30 days’ notice, and which may be difficult to extend or replace. We provide NGL
sales  and  distribution  services,  refined  products  terminals,  crude  oil  pipeline  services  and  above-ground  storage  services  that  support  various  commercial
customers. As these contracts expire, we may have to negotiate extensions or renewals with existing suppliers and customers or enter into new contracts with other
suppliers and customers. We may be unable to obtain new contracts on favorable commercial terms, if at all. We also may be unable to maintain the economic
structure of a particular contract with an existing customer or the overall mix of our contract portfolio. For example, depending on prevailing market conditions at
the  time  of  a  contract  renewal,  gathering  and  processing  customers  with  percent-of-proceeds  contracts  may  choose  to  switch  to  fee-based  gathering  and
transportation contracts, or a producer with whom we have a natural gas purchase contract may choose to enter into a transportation contract with us and retain title
to its natural gas. To the extent we are unable to renew our existing contracts on terms that are favorable to us or successfully manage our overall contract mix over
time, our revenue, gross margin and cash flows could decline and our ability to make distributions to our unitholders could be materially and adversely affected.

A significant increase in motor fuel costs or other commodity prices may adversely affect our profits.

Motor fuel is a significant operating expense for us in connection with the operation of both our crude oil pipelines and storage and NGL distribution and sales
segments. Although contracts typically have a fuel surcharge, a significant increase in motor fuel prices will result in increased transportation costs to us. The price
and supply of motor fuel is unpredictable and fluctuates based on events we cannot control, such as geopolitical developments, supply and demand for oil and gas,
actions  by  oil  and  gas  producers,  war  and  unrest  in  oil-producing  countries  and  regions,  regional  production  patterns  and  weather  concerns.  As  a  result,  any
increases in these prices may adversely affect our profitability and competitiveness.

Environmental, health and safety costs and liabilities, and changing environmental, health and safety regulation, could have a material adverse effect on our
financial position, results of operations and cash flows.

Our operations are subject to various environmental, health and safety requirements and potential liabilities under extensive federal, state and local laws and
regulations. Further, we cannot ensure that existing environmental, health and safety laws or regulations will not be revised or that new laws or regulations will not
be  adopted  or  become  applicable  to  us.  Governmental  authorities  have  the  power  to  enforce  compliance  with  applicable  laws,  regulations  and  permits  and  to
subject violators to civil and criminal penalties, including substantial fines, injunctions or both. Certain environmental laws, including CERCLA and analogous
state laws and regulations, may impose strict, joint and several liability for costs required to clean-up and restore sites where hazardous substances or hydrocarbons
have been disposed or otherwise released. Moreover, third parties, including neighboring landowners, may also have the right to pursue legal actions to enforce
compliance or to recover for personal injury and property damage allegedly caused by the release of hazardous substances, hydrocarbons or other waste products
into the environment. Failure to comply with these requirements may expose us to fines, penalties, remedial liabilities or interruptions or delays in our operations
that could have a material adverse effect on our financial position, results of operations and cash flows.

In addition, future environmental, health and safety law developments, such as stricter laws, regulations, permits or enforcement policies, could significantly

increase some costs of our operations. Areas of potential future environmental, health and safety law development include the following items:

Greenhouse Gases/Climate Change . From time to time, the U.S. Congress has considered legislation to reduce emissions of greenhouse gases but no such
legislation has yet been adopted by Congress. In addition, some states, including states in which our facilities or operations are located, have individually or in
regional cooperation, imposed restrictions on greenhouse gas emissions under various policies and approaches, including establishing a cap on emissions, requiring
efficiency measures, or providing incentives for pollution reduction, use of renewable energy sources, or use of replacement fuels with lower carbon content.

The EPA initiated  the regulation  of greenhouse gases under its Clean Air Act authority  in 2009, requiring  the reporting  of greenhouse gas emissions from
specified  large  greenhouse  gas  emission  sources  in  the  United  States  beginning  in  2011  for  emissions  occurring  in  2010.  On  November  30,  2010,  the  EPA
published a final rule expanding its existing GHG emissions reporting rule for petroleum and natural gas facilities, including natural gas transmission compression
facilities that emit 25,000 metric tons or more of carbon dioxide equivalent per year. The rule, which went into effect on December 30, 2010, requires reporting of
greenhouse gas emissions by regulated facilities to the EPA annually. In October 2015, the EPA amended and expanded greenhouse gas reporting requirements to
all segments of the crude oil and natural gas industry, including gathering and compression facilities and blowdowns of natural gas transmission pipelines, starting
with the 2016 reporting year, and in January 2016, the EPA proposed additional revisions to leak detection methodology to align the reporting rule with the new
source performance standards. A number of our facilities, including our Bazor Ridge and Chatom systems, are subject to greenhouse gas reporting, and we have
filed annual emission reports for these facilities since March 2012.

Federal agencies also have begun directly regulating emissions of methane (a greenhouse gas) from crude oil and natural gas operations. In June 2016, the
EPA issued new source performance standards for methane from new and modified crude oil and natural gas industry sources. These regulations will expand upon
the  2012  EPA  new  source  performance  standard  rulemaking  for  equipment-specific  emissions  control  requirements,  and  will,  for  example,  require  additional
controls for pneumatic controllers and pumps, and compressors, and impose leak detection and repair requirements for natural gas compressor and booster stations.
However,  the  EPA is currently  engaged  in  rulemaking  to  stay  the  effective  date  of  these  rules.  The EPA had  announced  plans  to  begin work on regulations  to
regulate methane emissions from existing oil and gas sources. In November 2016, the BLM issued rules requiring additional efforts by producers to reduce venting,
flaring, and leaking of natural gas produced on federal and Native American lands. In December 2017, implementation of this rule was delayed until January 2019.
On an international level, in April 2016, the United States became one of almost 175 nations that signed onto the Paris Agreement, an international climate change
agreement  that  calls  for countries  to set  their  own greenhouse  gas emissions  targets  and be transparent  about the measures  each  country  will use to achieve  its
greenhouse gas emissions targets. However, in June 2017, President Trump announced that the United States plans to withdraw from the Paris Agreement and to
seek negotiations either to reenter the Paris Agreement on different terms or establish a new framework agreement.

The  adoption  and  implementation  of  any  international,  federal,  state  or  local  regulations  imposing  reporting  obligations  on,  or  limiting  emissions  of
greenhouse  gases  from,  our  equipment  and  operations  could  require  us  to  incur  significant  costs  to  reduce  emissions  of  greenhouse  gases  associated  with  our
operations  or  could  adversely  affect  demand  for  the  commodities  that  we  buy  or  sell,  transport,  store  or  otherwise  handle  in  connection  with  our  midstream
services.  In  addition,  the  adoption  and  implementation  of  any  international,  federal,  state  or  local  regulations  imposing  reporting  obligations  on,  or  limiting
emissions of greenhouse gases from, the equipment and operations of our producer customers could affect their ability to produce the commodities that we

33

buy or sell, transport, store or otherwise handle in connection with our midstream services. The potential increase in our operating costs could include among other
things costs to operate and maintain our facilities, install new emission controls on our facilities, acquire allowances to authorize our greenhouse gas emissions,
pay taxes related to our greenhouse gas emissions, and administer and manage a greenhouse gas emissions program. We may not be able to recover such increased
costs through customer prices or rates. In addition, changes in regulatory policies that result in a reduction in the demand for hydrocarbon products that are deemed
to contribute  to greenhouse  gases,  or restrictions  on their  use, may reduce  volumes available  to us for processing,  transportation,  marketing  and storage.  These
developments  could  have  a  material  adverse  effect  on  our  financial  position,  results  of  operations  and  cash  flows.  Finally,  increasing  attention  to  the  risks  of
climate change has resulted in an increased possibility of lawsuits brought by public and private entities against oil and gas companies in connection with their
greenhouse gas emissions. Should we be targeted by any such litigation, we may incur liability, which, to the extent that societal pressures or political or other
factors are involved, could be imposed without regard to the company’s causation of or contribution to the asserted damage, or to other mitigating factors.

Hydraulic Fracturing . Certain of our customers employ hydraulic fracturing techniques to stimulate natural gas and crude oil production from unconventional
geological formations (including shale formations),  which entails the injection of pressurized fracturing fluids (consisting of water, sand and certain chemicals)
into  a  well  bore.  From  time  to  time,  the  United  States  has  considered  the  adoption  of  legislation  to  provide  for  federal  regulation  of  hydraulic  fracturing,  and
several governmental reviews, including a study being performed by the EPA, are underway that focus on environmental aspects of hydraulic fracturing activities.
Moreover, some states and localities, have adopted, and others are considering adopting, regulations or ordinances that could restrict hydraulic fracturing in certain
circumstances,  or  that  would impose  higher  taxes,  fees  or  royalties  on  natural  gas  production,  or  otherwise  limit  the  use  of  the  technique.  States  could  elect  to
prohibit  high  volume  hydraulic  fracturing  altogether,  following  the  approach  taken  by  the  State  of  New  York  in  2015.  Increased  regulation  to  the  hydraulic
fracturing  process  also  could  lead  to  a  reduction  in  crude  oil  and  natural  gas  drilling  activities  using  hydraulic  fracturing  techniques,  whereas  increased  public
opposition  to  activities  using  such  techniques  may  result  in  operational  delays,  restriction  or  litigation.  Additional  legislation  or  regulation  could  also  lead  to
operational delays or increased operating costs in the production of crude oil and natural gas incurred by our customers or could make it more difficult for them to
perform hydraulic fracturing. If these legislative and regulatory initiatives cause a material decrease in the drilling or production of new wells and related servicing
activities, it may affect the volume of hydrocarbon projects available to our midstream business and have a material adverse effect on our financial position, results
of operations and cash flows.

The value of our interests in operations located in the U.S. Gulf of Mexico could be adversely impacted by increased regulation and continuing regulatory
uncertainty.

Operations in the U.S. Gulf of Mexico have been subject to an increasingly stringent regulatory environment including government regulations focused on
offshore  operating  requirements,  spill  cleanup,  and  enforcement  matters.  These  regulations  also  implement  additional  safety  and  certification  requirements
applicable  to  offshore  activities  in  the  U.S.  Gulf  of  Mexico.  Certain  operating  assets  such  as  our  High  Point  system,  Destin  system,  Okeanos  system  and  our
Offshore Texas system, and certain non-operated interests in operations located in the U.S. Gulf of Mexico that we currently hold or may hold in the future, are
subject to such increased regulations, including our non-operated interests in Delta House. In addition, the Bureau of Safety and Environmental Enforcement and
the Bureau of Ocean Energy Management has increased regulatory activity including shortening the time period a line may be inactive before it must be removed
or  abandoned  and  requiring  additional  supplemental  bonding or  other  forms  of  providing  abandonment  security  for  offshore  facilities  on the Outer  Continental
Shelf. These new regulations have increased our operating costs, and the operating costs of our producer customers. As a result, the value of our interests in these
operations may be adversely affected by these regulations. Future regulatory requirements could delay activities from these operations and reduce our revenues,
resulting  in reduced  cash  flows and profitability.  Moreover,  any failure  to satisfy  these regulatory  requirements  by our producing  customers  could result in the
commencement  of  enforcement  proceedings  or  the  taking  of  other  remedial  action,  including  assessing  civil  penalties,  ordering  suspension  of  operations  or
production, or initiating procedures to cancel leases, which, if upheld, could materially reduce the demand for our services.

Significant portions of our pipeline systems have been in service for several decades and we have a limited ownership history with respect to all of our assets.
There  could  be  unknown  events  or  conditions  or  increased  maintenance  or  repair  expenses  and  downtime  associated  with  our  pipelines  that  could  have  a
material adverse effect on our business and results of operations.

Significant portions of the pipeline systems that we have purchased had been in service for many decades prior to our purchase. Consequently, our executive
management  team  has  a  limited  history  of  operating  such  assets.  There  may  be  historical  occurrences  or  latent  issues  regarding  our  pipeline  systems  that  our
executive management may be unaware of and that may have a material adverse effect on our business and results of operations. The age and condition of our
pipeline systems could also result in increased maintenance or repair expenditures, and any downtime associated with increased maintenance and repair activities
could materially reduce our revenue. Any significant increase in maintenance and repair expenditures or loss of revenue due to the age or condition

34

of our pipeline systems could adversely affect our business and results of operations and our ability to make cash distributions to our unitholders.

We may incur significant costs and liabilities as a result of increasingly stringent pipeline safety regulation, including pipeline integrity management program
testing and related repairs.

Pursuant to the Pipeline Safety Improvement Act of 2002, as reauthorized and amended by the Pipeline Inspection, Protection, Enforcement and Safety Act of
2006,  the  DOT,  through  PHMSA,  has  adopted  regulations  requiring  pipeline  operators  to  develop  integrity  management  programs  for  transmission  pipelines
located in “high consequence areas,” including high population areas, unless the operator effectively demonstrates by risk assessment that the pipeline could not
affect the area. The regulations require operators, including us, to:

perform ongoing assessments of pipeline integrity;
identify and characterize applicable threats to pipeline segments that could impact a high consequence area;

•
•
• maintain processes for data collection, integration and analysis;
•
•

repair and remediate pipelines as necessary; and
implement preventive and mitigating actions.

In addition, many states have adopted regulations similar to existing DOT regulations for intrastate gathering and transmission lines. Although many of our
natural gas facilities fall within a class that is not subject to these requirements, we may incur significant costs and liabilities associated with repair, remediation,
preventative or mitigation measures associated with our non-exempt pipelines, particularly our AlaTenn and Midla pipelines. We currently estimate that we will
incur future costs of approximately $2 million during 2018 to complete the testing required by existing DOT regulations. This estimate does not include the costs,
if  any,  for  repair,  remediation,  preventative  or  mitigating  actions  that  may  be  determined  to  be  necessary  as  a  result  of  the  testing  program,  which  could  be
substantial. Such costs and liabilities might relate to repair, remediation, preventative or mitigating actions that may be determined to be necessary as a result of the
testing program, as well as lost cash flows resulting from shutting down our pipelines during the pendency of such repairs. Additionally, should we fail to comply
with DOT regulations, we could be subject to penalties and fines.

The  Pipeline  Safety,  Regulatory  Certainty,  and  Job  Creation  Act  of  2011  (“2011  Pipeline  Safety  Act”),  which  became  law  in  January  2012,  increases  the
penalties for safety violations, establishes additional safety requirements for newly constructed pipelines and requires studies of safety issues that could result in
the  adoption  of  new  regulatory  requirements  for  existing  pipelines.  More  recently,  in  June  2016,  President  Obama  signed  the  Protecting  our  Infrastructure  of
Pipelines  and  Enhancing  Safety  Act  of  2016  (“2016  Pipeline  Safety  Act”)  that  extends  PHMSA’s  statutory  mandate  through  2019  and,  among  other  things,
requires  PHMSA to  complete  certain  of its  outstanding  mandates  under  the  2011 Pipeline  Safety  Act  and  develop  new safety  standards  for  natural  gas  storage
facilities by June 22, 2018. The 2016 Pipeline Safety Act also empowers PHMSA to address imminent hazards by imposing emergency restrictions, prohibitions
and safety measures on owners and operators of gas or hazardous liquid pipeline facilities without prior notice or an opportunity for a hearing.

In April 2015, PHMSA proposed rulemaking that would require leak detection for all “hazardous liquid pipelines” such as crude oil and NGL pipelines and
require periodic assessment of hazardous liquid pipelines not already covered by the integrity management requirements. On January 13, 2017, PHMSA issued a
final rule requiring the use of leak detection systems beyond HCAs to all regulated, non-gathering hazardous liquid pipelines and requiring integrity assessments at
least once every ten years of onshore, piggable, transmission hazardous liquid pipeline segments located outside of HCAs. The effective date of this final rule is
currently uncertain due to a regulatory freeze implemented by the Trump administration. In addition, in March 2016, PHMSA announced a proposed rulemaking
that  would impose  new or  more  stringent  requirements  for  certain  gas  lines  and  gathering  lines  including,  among  other  things,  expanding  certain  of  PHMSA’s
current regulatory safety programs for gas pipelines in newly defined “moderate consequence areas” that contain as few as 5 dwellings within a potential impact
area; requiring gas pipelines installed before 1970 and thus excluded from certain pressure testing obligations to be tested to determine their maximum allowable
operating pressures (“MAOP”); and requiring certain onshore and offshore gathering lines in Class I areas to comply with damage prevention, corrosion control,
public education, MAOP limits, line markers and emergency planning standards. Additional requirements proposed by this proposed rulemaking would increase
PHMSA’s  integrity  management  requirements  and  also  require  consideration  of  seismicity  in  evaluating  threats  to  pipelines.  Such  legislative  and  regulatory
changes  could  have  a  material  effect  on  our  operations  and  costs  of  transportation  services.  Additionally,  legislative  and  regulatory  changes  may  also  result  in
higher penalties for the violation of federal pipeline safety regulations and the costs associated with compliance may have a material effect on our operations. We
cannot predict with any certainty at this time the terms of any new laws or rules or the costs of compliance associated with such requirements.

35

A  downgrade  in  our  credit  ratings  could  impact  our  access  to  capital  and  costs  of  doing  business,  and  maintaining  credit  ratings  is  under  the  control  of
independent third parties.

Rating agencies may reevaluate our ratings, and any additional actual or anticipated downgrades in such credit ratings could limit our ability to access credit
and capital markets, including to finance the SXE Transactions, or to restructure or refinance our indebtedness. On November 1, 2017, S&P and Moody’s both
announced  that  our  long  term  credit  rating  had  been  placed  on  watch  as  a  result  of  the  announcement  of  the  SXE  Transactions.  As  a  result  of  any  potential
downgrades, future financing or refinancing, including to finance the SXE Transactions, may result in higher borrowing costs and require more restrictive terms
and covenants, including obligations to post collateral with third parties, which may further restrict our operations and negatively impact liquidity.

Credit rating agencies perform independent analysis when assigning credit ratings. The analysis includes a number of criteria including, but not limited to,
business composition, market and operational risks, as well as various financial tests. Credit rating agencies continue to review the criteria for industry sectors and
various debt ratings and may make changes to those criteria from time to time. Credit ratings are not recommendations to buy, sell or hold investments in the rated
entity. Ratings are subject to revision or withdrawal at any time by the rating agencies, and we cannot assure you that we will maintain our current credit ratings.

We  intend  to  grow  our  business  in  part  by  continuing  to  seek  strategic  acquisition  opportunities.  If  we  are  unable  to  make  acquisitions  on  economically
acceptable terms from third parties, our future growth will be limited, and the acquisitions we do make may reduce, rather than increase, our cash generated
from operations on a per unit basis.

Our ability to grow depends, in part, on our ability to make acquisitions that increase our cash generated from operations on a per unit basis. The acquisition
component  of  our  strategy  is  based,  in  large  part,  on  our  expectation  of  ongoing  divestitures  of  midstream  energy  assets  by  industry  participants.  A  material
decrease in such divestitures would limit our opportunities for future acquisitions and could adversely affect our ability to grow our operations and increase our
distributions to our unitholders.

If we are unable to make accretive acquisitions from third parties, whether because we are: (i) unable to identify attractive acquisition candidates or negotiate
acceptable purchase contracts, (ii) unable to obtain financing for these acquisitions on economically acceptable or attractive terms or (iii) outbid by competitors or
for any other reason, then our future growth and ability to increase distributions will be limited. Furthermore, even if we do make acquisitions that we believe will
be accretive, these acquisitions may nevertheless result in a decrease in the cash generated from operations on a per unit basis.

Any acquisition involves potential risks, including, among other things:

•
•
•

•
•
•
•
•
•
•

assumptions about volumes, revenue, decline rates, drilling activity and cost savings, including synergies;
inability to secure adequate customer commitments to use the acquired systems or facilities;
inability to integrate successfully the assets or businesses we acquire, particularly given the relatively small size of our management team and its
limited history with certain assets;
assumption of unknown liabilities, including environmental contamination;
limitations on rights to indemnity from the seller;
assumptions about the overall costs of equity or debt;
diversion of management’s and employees’ attention from other business concerns;
entry of competitors in the markets where the acquired business competes;
difficulties operating in new geographic areas and business lines; and
customer or key employee losses at the acquired businesses.

If  we  consummate  any  future  acquisitions,  our  capitalization  and  results  of  operations  may  change  significantly,  and  our  unitholders  will  not  have  the
opportunity  to  evaluate  the  economic,  financial  and  other  relevant  information  that  we  will  consider  in  determining  the  application  of  these  funds  and  other
resources.

Our construction of new assets may not result in increased revenue and will be subject to regulatory, environmental, political, legal and economic risks, which
could adversely affect our results of operations and financial condition.

One of the ways we intend to grow our business is through organic growth projects. The construction of additions or modifications to our existing systems and
the  construction  of  new  midstream  assets  involve  numerous  regulatory,  environmental,  political,  legal  and  economic  uncertainties  that  are  beyond  our  control,
including the availability  of skilled labor, equipment and materials  to complete expansion projects  and potential changes in federal, state and local statutes and
regulations,  including  environmental  requirements,  that  may  delay  or  prevent  a  project  from  proceeding  or  increase  the  anticipated  cost  of  the  project.  Such
expansion projects may also require the expenditure of significant amounts of capital, and financing may not be available on economically acceptable terms or at
all. If we undertake these projects, they may not be completed on schedule, at the budgeted

36

cost, or at all. Cost overruns on construction projects may cause unexpected changes in project economics. Moreover, our revenue may not increase immediately
upon the expenditure of funds on a particular project.

For instance, if we expand a pipeline, the construction may occur over an extended period of time, yet we will not receive any material increases in revenue
until  the  project  is  completed  and  placed  into  service.  Moreover,  we could  construct  facilities  to  capture  anticipated  future  growth  in  production  in  a  region  in
which such growth does not materialize or only materializes over a period materially longer than expected. Since we are not engaged in the exploration for, and
development  of,  natural  gas  and  crude  oil  reserves,  we  often  do  not  have  access  to  third-party  estimates  of  potential  reserves  in  an  area  prior  to  constructing
facilities in that area. To the extent we rely on estimates of future production in our decision to construct additions to our systems, such estimates may prove to be
inaccurate  as  a  result  of  the  numerous  uncertainties  inherent  in  estimating  quantities  of  future  production.  As  a  result,  new  facilities  may  not  attract  enough
throughput to achieve our expected investment return, which could adversely affect our results of operations and financial condition.

In addition, the construction of additions to our existing gathering and transportation assets, or the construction of new gathering and transportation assets,
may require us to obtain new rights-of-way. We may be unable to obtain such rights-of-way and may, therefore, be unable to connect new natural gas volumes to
our systems or capitalize on other attractive expansion opportunities. Additionally, it may become more expensive for us to obtain new rights-of-way or to renew
existing rights-of-way. If the cost of renewing or obtaining new rights-of-way increases materially, our cash flows could be adversely affected.

In  connection  with  our  expansion  capital  programs,  we  have  agreed,  and  may  in  the  future  agree,  to  construct  oil  and  gas  gathering  pipelines  to  service
existing and future oil and gas properties, which involves potential risks.

In connection with our expansion capital programs, we have agreed, and may in the future agree, at our cost and expense, to design, acquire right-of-way for,
obtain all permits from governmental authorities for, procure materials for, construct, operate, and maintain additional gathering pipelines for connection to certain
current and future producing crude oil and natural gas properties. There are risks involved with such obligations, including:

•
•
•

•

•

general construction cost overruns and delays resulting from numerous factors, many of which may be out of our control;
the inability to obtain required permits for the pipelines;
the  inability  to  obtain  rights-of-way  for  the  gathering  pipelines,  which  may  result  in  pipelines  being  re-routed,  which  itself  could  result  in  cost
overruns and delays;
the  risk  associated  with  producer’s  exploration  and  production  activities  and  the  associated  potential  failure  of  the  gathering  pipelines  to  generate
attractive cash flows given our obligation to construct and operate them; and
title issues or environmental or regulatory compliance matters or liabilities or accidents associated with the construction or operation of the pipelines.

We currently expect to fund these costs with borrowings under our revolving credit facility or by accessing the capital markets. If we are unable to finance the
expansion costs with existing liquidity, we could be required to seek alternative sources of liquidity, which could be costly or may not be available. In the event
expansion and extension of the crude oil and natural gas properties is significantly more expensive than we expect or we are unable to obtain financing for such
construction, it could have a material adverse effect on our financial condition, including our results of operations and cash flows.

Our business involves  many  hazards, operational  risks  and litigation  risks, some  of  which may not be  fully  covered  by  insurance. If  a significant  accident,
event or judgment occurs for which we are not adequately insured, our operations and financial results could be adversely affected.

Our  operations  are  subject  to  all  of  the  risks  and  hazards  inherent  in  the  gathering,  compressing,  treating,  processing  and  transportation  of  natural  gas,

including:

•

•
•
•
•

damage  to  pipelines,  plants,  storage  facilities,  related  equipment  and  surrounding  properties  caused  by  hurricanes,  tornadoes,  floods,  fires,
earthquakes and other natural disasters and acts of terrorism;
inadvertent damage from construction, vehicles, farm and utility equipment;
leaks of natural gas and other hydrocarbons or losses of natural gas as a result of the malfunction of equipment or facilities;
ruptures, fires and explosions; and
other hazards that could also result in personal injury and loss of life, pollution and suspension of operations.

37

These risks could result in substantial losses due to personal injury or loss of life, severe damage to and destruction of property and equipment and pollution or
other environmental damage. These risks may also result in curtailment or suspension of our operations. In addition, we have been, and are likely to continue to be,
a defendant in various legal proceedings and litigation arising in the ordinary course of business, both as a result of these operating hazards and risks and as a result
of other aspects of our business. A natural disaster or other hazard affecting the areas in which we operate could have a material adverse effect on our operations.

We are not fully insured against all risks inherent in our business. For example, we do not have any casualty insurance on our underground pipeline systems
that  would  cover  damage  to  the  pipelines.  We  are  self-insured  for  general  and  product,  workers’  compensation  and  automobile  liabilities  up  to  predetermined
amounts above which third-party insurance applies. Additionally, we do not have business interruption/ loss of income insurance that would provide coverage in
the event of damage to any of our underground facilities. In addition, although we are insured for environmental pollution resulting from environmental accidents
that occur on a sudden and accidental basis, we may not be insured against all environmental accidents that might occur, some of which may result in toxic tort
claims. We cannot guarantee that our insurance will be adequate to protect us from all material expenses related to potential future claims for personal injury and
property damage. If a significant accident or event occurs for which we are not fully insured, it could have a material adverse effect on our operations and financial
condition. Furthermore, we may not be able to maintain or obtain insurance of the type and amount we desire at reasonable rates. As a result of market conditions,
premiums  and  deductibles  for  certain  of  our  insurance  policies  may  substantially  increase.  In  some  instances,  certain  insurance  could  become  unavailable  or
available  only  for  reduced  amounts  of  coverage.  Additionally,  we  may  be  unable  to  recover  from  prior  owners  of  our  assets,  pursuant  to  our  contractual
indemnification rights for potential environmental liabilities.

Our interstate natural gas, crude oil and NGL pipelines are subject to regulation by FERC, which could adversely affect our ability to make distributions to
our unitholders.

Our AlaTenn, Trans-Union and Midla interstate natural gas transportation systems, our Destin pipeline, which we operate and own 66.7%, and a portion of our
High Point system, are subject to regulation by FERC, under the NGA. Under the NGA, the rates for and terms of conditions of service on these interstate facilities
must be just and reasonable and not unduly discriminatory. The rates and terms and conditions for our interstate pipeline services are set forth in tariffs that must
be filed with and approved by FERC. Pursuant to FERC’s jurisdiction over rates, existing rates may be challenged by complaint and proposed rate increases may
be  challenged  by  protest.  Any  successful  complaint  or  protest  against  our  rates  could  have  an  adverse  impact  on  our  revenue  associated  with  providing
transportation service.

Under  the  NGA,  FERC  has  the  authority  to  regulate  companies  that  provide  natural  gas  pipeline  transportation  services  in  interstate  commerce.  FERC’s

authority over such companies includes such matters as:

rates, terms and conditions of service;
the types of services interstate pipelines may offer to their customers;
the certification and construction of new facilities;
the acquisition, extension, disposition or abandonment of facilities;
the maintenance of accounts and records;
relationships between affiliated companies involved in certain aspects of the natural gas business;
the initiation and discontinuation of services;

•
•
•
•
•
•
•
• market manipulation in connection with interstate sales, purchases or transportation of natural gas; and
•

participation by interstate pipelines in cash management arrangements.

The EP Act 2005 amended the NGA to add an anti-manipulation provision. Pursuant to the amended NGA, FERC established rules prohibiting energy market
manipulation.  Also,  FERC’s  rules  require  interstate  pipelines  and  their  affiliates  to  adhere  to  Standards  of  Conduct  that,  among  other  things,  require  that
transportation employees function independently of marketing employees. We are subject to audit by FERC of our compliance in general, including adherence to
all its rules and regulations. A violation of these rules, or any other rules, regulations or orders issued or administered by FERC, may subject us to civil penalties,
disgorgement  of  certain  profits,  or  appropriate  non-monetary  remedies  imposed  by  FERC.  In  addition,  the  EP  Act  2005  amended  the  NGA  and  the  NGPA,  to
increase  civil  and criminal  penalties  for  any violation  of the NGA, NGPA and any rules, regulations  or orders of FERC. Under the EP Act 2005, the FERC is
authorized  to  impose  civil  penalties  of  up  to  $1,000,000  per  violation,  per  day  for  violations  of  the  NGA,  the  NGPA  or  the  rules,  regulations,  restrictions,
conditions  and  orders  promulgated  under  those  statutes.  This  maximum  penalty  authority  established  by  statute  will  continue  to  be  adjusted  periodically  for
inflation. The current maximum daily penalty for a violation is $1,238,271.

Additionally, existing rates may not reflect our current costs of operations, which may have risen since the last time our rates were approved by FERC.

Our Bakken crude oil gathering system, FERC-regulated American Panther, LLC offshore liquids pipelines (known as the Tiger Shoals and MP 77 offshore
pipeline systems) and the Tri-States and Wilprise NGL pipelines, in which we have equity investments, are regulated as common carrier interstate pipelines by the
FERC under the ICA, the EP Act 1992 and the rules and regulations promulgated under those laws. FERC regulations require that rates and terms and conditions
of service for interstate service pipelines that transport crude oil be just and reasonable and must not be unduly discriminatory or confer any undue preference upon
any shipper. FERC’s regulations also require interstate common carrier petroleum pipelines to file with FERC and publicly post tariffs stating their interstate
transportation rates and terms and conditions of service.

Rates of interstate liquids pipelines are currently regulated by FERC primarily through an annual indexing methodology, under which pipelines increase or
decrease their rates in accordance with an index adjustment specified by FERC. For the five-year period beginning on July 1, 2016, FERC established an annual
index adjustment equal to the change in the producer price index for finished goods plus 1.23%. Under FERC’s regulations, liquids pipelines can request a rate
increase that exceeds the rate obtained through application of the indexing methodology by using a cost-of-services approach, but only after the pipeline establishes
that a substantial divergence exists between the actual costs experienced by the pipeline and the rates resulting from application of the indexing methodology.

Under the ICA, FERC or interested persons may challenge existing or proposed new or changed rates, services, or terms and conditions of service. FERC is
authorized to investigate such charges and may suspend the effectiveness of a new rate for up to seven months. FERC could require a common carrier pipeline to
collect rates subject to refund until completion of an investigation during which FERC could find that the new or changed rate is unlawful. In contrast, FERC has
clarified that initial rates and terms of service agreed upon with committed shippers in a transportation services agreement are not subject to protest or a cost-of-
service analysis where the pipeline held an open season offering all potential shippers service on the same terms.

A successful rate challenge could result in a common carrier pipeline paying refunds of revenue collected in excess of the just and reasonable rate, together
with  interest  for  the  period  the  rate  was  in  effect,  if  any.  FERC  may  also  order  a  pipeline  to  reduce  its  rates  prospectively,  and  may  require  a  common  carrier
pipeline to pay shippers reparations retroactively for rate overages for a period of up to two years prior to the filing of a complaint. FERC also has the authority to
change terms and conditions of service if it determines that they are unjust or unreasonable or unduly discriminatory or preferential.

Our intrastate natural gas and gathering transportation and sales services are subject to regulation by state and federal agencies, which could adversely affect
our ability to make cash distributions to our unitholders.

Certain of our intrastate natural gas pipeline operations are subject to regulation by various agencies of the states in which they are located. Most states have
agencies  that  possess  the  authority  to  review  and  authorize  natural  gas  transportation  transactions  and  the  construction,  acquisition,  abandonment  and
interconnection of physical facilities. Some states also have state agencies that regulate transportation rates, service terms and conditions and contract pricing to
ensure their reasonableness and to ensure that the intrastate pipeline companies that they regulate do not discriminate among similarly situated customers. Such
agencies could limit our ability to increase our rates or order us to reduce our rates and pay refunds to shippers. State agencies can also regulate whether a service
may be provided or cancelled. If state agencies in the states in which we offer intrastate transportation services change their policies or aggressively regulate our
rates or terms and conditions of service, it could also adversely affect our ability to make cash distributions to our unitholders.

Certain of our intrastate natural gas pipelines transport gas in interstate commerce that is subject to FERC jurisdiction under Section 311 of the NGPA or are
exempt  from  FERC  jurisdiction  as  Hinshaw  pipelines  but  have  received  blanket  authorization  to  transport  natural  gas  on  behalf  of  interstate  pipelines.  The
maximum rates for services provided under Section 311 of the NGPA may not exceed a “fair and equitable rate,” as defined in the NGPA. The rates are generally
subject to review every five years by FERC or by an appropriate state agency. The inability to obtain approval of rates at acceptable levels could result in refund
obligations and an inability to make cash distributions to our unitholders.

Intrastate  natural  gas  pipelines,  which  operate  entirely  within  a  single  state,  are  generally  not  subject  to  FERC’s  jurisdiction  under  the  NGA.  Hinshaw
pipelines operate within a single state but may receive gas from outside their state without becoming subject to FERC jurisdiction under the NGA. Specifically, a
Hinshaw pipeline is exempt from FERC’s general NGA regulation if: (1) it receives natural gas at or within the boundary of a state; (2) all the gas is consumed
within  that  state;  and  (3)  the  pipeline  is  regulated  by  a  state  commission.  Hinshaw  pipelines  may  also  receive  authorization  under  Part  284,  subpart  G  of  the
FERC’s regulations to transport natural gas on behalf of interstate pipelines or a local distribution company served by an interstate pipeline.

Certain  of  our  pipelines  which  transport  gas  in  interstate  commerce  are  “Hinshaw”  pipelines  exempt  from  the  jurisdiction  of  the  FERC  jurisdiction  under
Section 1(c) of the NGA, and we may have additional Hinshaw pipelines in the future. Each of our current Hinshaw pipelines has received a “blanket certificate”
under 18 C.F.R. Section 284.244 to transport gas. The maximum

39

rates for services provided the blanket certificate may not exceed a “fair and equitable rate,” as defined in the FERC Regulations. The rates are generally subject to
review every five years by FERC or by an appropriate state agency. The inability to obtain approval of rates at acceptable levels could result in refund obligations
and an inability to make cash distributions to our unitholders.

The FERC’s anti-manipulation rules apply to non-jurisdictional entities to the extent the activities are conducted “in connection with” gas sales, purchases or
transportation subject to FERC jurisdiction. The new anti-manipulation rules do not apply to activities that relate only to intrastate or other non-jurisdictional sales
or gathering, but only to the extent such transactions do not have a “nexus” to jurisdictional transactions. As noted above, the FERC’s civil penalty authority under
the EP Act of 2005 would apply to violations of these rules to the extent applicable to our intrastate natural gas services.

The application of certain FERC policy statements could affect the rate of return on our equity that we are allowed to recover through rates and the amount of
any allowance our interstate systems can include for income taxes in establishing their rates for service, which would in turn impact our revenue or equity
earnings.

FERC currently allows partnerships, including MLPs, to include in their cost-of-service an income tax allowance if the partnership’s owners have actual or
potential income tax liability, a matter that will be reviewed by FERC on a case-by-case basis. In July 2016, the United States Court of Appeals for the District of
Columbia Circuit issued its opinion in United Airlines, Inc., et al. v. FERC , finding that FERC had acted arbitrarily and capriciously when it failed to demonstrate
that permitting an interstate petroleum products pipeline organized as a limited partnership to include an income tax allowance in the cost of service underlying its
rates in addition to the discounted cash flow return on equity would not result in the pipeline partnership double-recovering the income tax liability of its investors.
The court vacated FERC’s order and remanded to FERC to consider mechanisms for demonstrating that there is no double recovery as a result of the income tax
allowance.  On  December  15,  2016,  FERC  issued  a  Notice  of  Inquiry  seeking  comment  on  how  to  address  any  double  recovery  resulting  from  income  tax
allowance policy. The ultimate outcome of this proceeding is not certain and could result in changes going forward to FERC’s treatment of income tax allowances
in the cost of service  or to the discounted  cash flow return  on equity.  On March  15, 2018, FERC issued an order  on remand  in the  United Airlines case and a
revised policy statement on income tax recovery that disallows income tax allowances for master limited partnerships in cost of service rates. In addition, FERC
issued  a  notice  of  proposed  rulemaking  on  March  15,  2018  that  proposes  to  require  all  interstate  natural  gas  pipelines  to  submit  cost  of  service  information  to
account  for  reductions  in  cost  of  service  resulting  from  FERC’s  new  policy  on  income  tax  allocations  for  master  limited  partnerships  and  the  reduction  in  the
corporate tax rate from the Tax Cuts and Jobs Act that went into effect January 1, 2018. As a result of this new policy and proposed rule, the cost of service rates of
our  interstate  pipelines  could  be  affected  to  the  extent  they  propose  new  rates  or  changes  to  their  existing  rates  or  if  their  rates  are  subject  to  complaint  or
challenged by FERC. However, we have considered the impact the proposed policy changes by the FERC would have on us, and we have determined that based on
the current rate structure on the Partnership's FERC regulated pipelines, the proposed changes are expected to have a negligible impact on the earnings and cash
flow of the Partnership. Although we cannot predict whether FERC will propose any additional policy revisions, we expect any such policy revisions will have
limited application to us, because a substantial majority of the Partnership's operations are not FERC regulated.

A change in the jurisdictional characterization or regulation of our assets by federal, state or local regulatory agencies or a change in policy by those agencies
could result in increased regulation of our assets which could materially and adversely affect our financial condition, results of operations and cash flows.

Gas gathering facilities and intrastate transportation facilities that do not provide interstate transmission services are exempt from the jurisdiction of FERC
under the NGA. In Docket No. CP12-9, the FERC determined that certain portions of our High Point system met the gathering exemption from regulation under
the NGA. Although FERC has not made any formal determinations with respect to any of our other facilities, we believe that our gathering and intrastate natural
gas pipelines and related facilities that are not engaged in providing interstate transmission services are engaged in exempt gathering and intrastate transportation
and, therefore, are not subject to FERC jurisdiction. We believe that our natural gas gathering pipelines meet the traditional tests that FERC has used to determine
if  a  pipeline  is  a  gathering  pipeline  and  is  therefore  not  subject  to  FERC’s  jurisdiction.  The  distinction  between  FERC-  regulated  transmission  services  and
federally unregulated gathering services is the subject of substantial ongoing litigation and, over time, FERC’s policy for determining which facilities it regulates
has changed. In addition, the distinction between FERC-regulated transmission facilities, on the one hand, and intrastate transportation and gathering facilities, on
the other, is a fact-based determination made by FERC on a case- by-case basis. 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, the  rates  for,  and  terms  and  conditions  of,  services  provided  by  such
facility would be subject to regulation by FERC under the NGA. Such regulation could decrease revenue, increase operating costs, and, depending upon the facility
in question, could adversely affect our results of operations and cash flows. In addition, if any of our facilities were found to have provided services or otherwise
operated in violation of the NGA or NGPA, this could result in the imposition of civil penalties as well as a requirement to disgorge charges collected for such
service in excess of the cost-based rate established by FERC.

40

Moreover, FERC regulation affects our gathering, transportation and compression business generally. FERC’s policies and practices across the range of its
natural gas regulatory activities, including, for example, its policies on open access transportation, market manipulation, ratemaking, capacity release and market
transparency and market center promotion, directly and indirectly affect our gathering business. In addition, the classification and regulation of our gathering and
intrastate transportation facilities also are subject to change based on future determinations by FERC, the courts or Congress.

State regulation of gathering facilities generally includes various safety, environmental and, in some circumstances, nondiscriminatory take requirements and
complaint-based rate regulation. We are subject to some state ratable take and common purchaser statutes. The ratable take statutes generally require gatherers to
take,  without  undue  discrimination,  natural  gas  production  that  may  be  tendered  to  the  gatherer  for  handling.  Similarly,  common  purchaser  statutes  generally
require gatherers to purchase without undue discrimination as to source of supply or producer. These statutes are designed to prohibit discrimination in favor of one
producer over another producer or one source of supply over another source of supply. States in which we operate that have adopted some form of complaint-based
regulation, like Texas, generally allow natural gas and crude oil producers and shippers to file complaints with state regulators in an effort to resolve grievances
relating to natural gas gathering access and rate discrimination.

In recent years, FERC’s efforts to promote open access, transparency, and the unbundling of interstate pipeline services has prompted a number of interstate
pipelines to transfer their non-jurisdictional gathering facilities to unregulated affiliates. As a result of these activities, natural gas gathering may begin to receive
greater regulatory scrutiny at both the state and federal levels. Such additional scrutiny could result in increased expenses to us and a resulting materially adverse
change in our finances.

We are subject to stringent environmental, safety and health laws and regulations that may expose us to significant costs and liabilities.         

Our operations are subject to stringent and complex federal, state and local environmental laws and regulations that govern the discharge of materials into the

environment or otherwise relate to environmental protection. Examples of these laws include:

•

•

•

•
•

•

•

•

•

the federal Clean Air Act and analogous state laws that restrict the emission of air pollutants from many sources, imposes various pre-construction,
monitoring,  and  reporting  requirements,  which  the  Environmental  Protection  Agency  has  relied  upon  as  authority  for  adopting  climate  change
regulatory initiatives;
the  federal  CERCLA  and  analogous  state  laws  that  regulate  the  cleanup  of  hazardous  substances  that  may  be  or  have  been  released  at  properties
currently or previously owned or operated by us or at locations to which our wastes are or have been transported for disposal;
the federal Clean Water Act and analogous state laws that regulate discharges of pollutants from facilities to state and federal waters and establishes
the extent to which waterways are subject to federal jurisdiction and rulemaking as protected waters of the United States;
the federal Oil Pollution Act of 1990 and analogous state laws that establish strict liability for releases of oil into waters of the United States;
U.S.  Department  of  the  Interior  regulations,  which  relate  to  offshore  oil  and  natural-gas  operations  in  U.S.  waters  and  impose  obligations  for
establishing  financial  assurances  for  decommissioning  activities,  liabilities  for  pollution  cleanup  costs  resulting  from  operations,  and  potential
liabilities for pollution damages;
the  federal  Resource  Conservation  and  Recovery  Act  of  1976  and  analogous  state  laws  that  impose  requirements  for  the  generation,  storage,
treatment, transport and disposal of solid and hazardous waste from our facilities;
the  Endangered  Species  Act  of  1973  and  analogous  state  laws  that  restrict  activities  that  may  affect  federally  or  state  identified  endangered  and
threatened species or their habitats through the implementation of operating restrictions or a temporary, seasonal, or permanent ban in affected areas;
the  Toxic  Substances  Control  Act,  and  analogous  state  laws  that  impose  requirements  on  the  use,  storage  and  disposal  of  various  chemicals  and
chemical substances at our facilities; and
the U.S. Occupational Safety and Health Act and analogous state laws that establish workplace standards for the protection of the health and safety of
employees,  including  the  implementation  of  hazard  communications  programs  designed  to  inform  employees  about  hazardous  substances  in  the
workplace, potential harmful effects of these substances, and appropriate control measures.

These laws and regulations may impose numerous obligations that are applicable to our operations, including the acquisition of permits to conduct regulated
activities, the incurrence of capital or operating expenditures to limit or prevent releases of materials from our pipelines and facilities, the imposition of specific
safety  and  health  criteria  addressing  worker  protection,  and  the  imposition  of  substantial  liabilities  and  remedial  obligations  for  pollution  resulting  from  our
operations.  Numerous  governmental  authorities,  such  as  the  EPA,  and  analogous  state  agencies,  have  the  power  to  enforce  compliance  with  these  laws  and
regulations and the permits issued under them, oftentimes requiring difficult and costly corrective actions. Failure to comply with these laws, regulations

41

and  permits  may  result  in  the  assessment  of  administrative,  civil  and  criminal  penalties,  the  imposition  of  remedial  obligations  and  the  issuance  of  injunctions
limiting or preventing some or all of our operations.

In  addition,  we  may  experience  a  delay  in  obtaining  or  be  unable  to  obtain  required  permits,  which  may  cause  us  to  lose  potential  and  current  customers,
interrupt our operations or delay expansion projects and limit our growth and revenue. See “Business - Environmental Matters - Air Quality and Climate Control”
in Item 1 of this Annual Report for more information about these matters.

There is a risk that we may incur significant environmental costs and liabilities in connection with our operations due to historical industry operations and
waste disposal practices, our handling of hydrocarbons and other wastes and potential emissions and discharges related to our operations. Joint and several strict
liability  may  be  incurred,  without  regard  to  fault,  under  certain  of  these  environmental  laws  and  regulations  in  connection  with  discharges  or  releases  of
hydrocarbons  and  other  wastes  on,  under  or  from  our  properties  and  facilities,  many  of  which  have  been  used  for  midstream  activities  for  a  number  of  years,
oftentimes by third parties not under our control. Private parties, including the owners of the properties through which our gathering or transportation systems pass
and facilities where our hydrocarbons and other wastes are taken for reclamation or disposal, may also have the right to pursue legal actions to enforce compliance,
as  well  as  to  seek  damages  for  non-compliance  with  environmental  laws  and  regulations  or  for  personal  injury  or  property  or  natural  resource  damage.  For
example, an accidental release from one of our pipelines could subject us to substantial liabilities arising from environmental cleanup and restoration costs, claims
made by neighboring landowners and other third parties for personal injury and property damage and fines or penalties for related violations of environmental laws
or regulations. We may not be able to recover all or any of these costs from insurance. In addition, changes in environmental laws and regulations occur frequently,
and any such changes that result in more stringent and costly waste handling, storage, transport, disposal or remediation requirements could have a material adverse
effect on our results of operations or financial position. See “Business - Environmental Matters” in Item 1 of this Annual Report for more information.

We may be unable to obtain or renew permits necessary for our operations or the operations we may acquire in future acquisitions.

Our facilities operate under a number of required federal and state permits, licenses and approvals with terms and conditions containing a significant number
of prescriptive limits and performance standards in order to operate. All of these permits, licenses, approvals, limits and standards require a significant amount of
monitoring, record keeping and reporting in order to demonstrate compliance with the underlying permit, license, approval, limit or standard. Noncompliance or
incomplete documentation of our compliance status may result in the imposition of fines, penalties and injunctive relief. A decision by a government agency to
deny or delay issuing a new or renewed material permit, license or approval, or to revoke or substantially modify an existing permit, license or approval, could
have a material adverse effect on our financial condition, including our results of operations and cash flows.

We do not own all of the land on which our pipelines and facilities are located, which could result in disruptions to our operations.

We do not own all of the land on which our pipelines and facilities have been constructed, and we are, therefore, subject to the possibility of more onerous
terms or increased costs to retain necessary land use if we do not have valid rights-of-way or if such rights-of-way lapse or terminate or do not allow us to change
our operations, or we may not be able to renew our contract leases on commercially reasonable terms or at all. We obtain the rights to construct and operate our
pipelines on land owned by third parties and governmental agencies for a specific period of time for specific types of operations. Our loss of these rights, through
our inability to renew right-of-way contracts or otherwise or our inability to amend these rights for new operations, could have a material adverse effect on our
business, results of operations, financial condition and ability to make cash distributions to our unitholders.

A failure in our operational systems or cyber security attacks on any of our facilities, or those of third parties, may adversely affect our financial results.

Our business is dependent upon our operational systems to process a large amount of data and complex transactions. If any of our financial, operational, or
other data processing systems fail or have other significant shortcomings or downtime, our financial results could be adversely affected. Our financial results could
also  be  adversely  affected  if  an  employee  causes  our  operational  systems  to  fail,  either  as  a  result  of  inadvertent  error  or  by  deliberately  tampering  with  or
manipulating  our  operational  systems.  In  addition,  dependence  upon  automated  systems  may  further  increase  the  risk  that  operational  system  flaws,  employee
tampering or manipulation of those systems will result in losses that are difficult to detect.

42

Due to increased technology advances, we have become more reliant on technology to help increase efficiency in our business. We use computer programs to
help run our financial and operational departments, and these systems may subject our business to increased risks. As of December 31, 2017, we did not maintain
effective controls over certain information technology general controls for a significant application used in the preparation of our financial statements. Any future
cyber security attacks that affect our facilities, our customers and any financial data, including as a result of our inability to adequately restrict user and privileged
access to our financial application, programs and data, could have a material adverse effect on our business. In addition, cyber-attacks on our financial, customer
and employee data may result in financial loss and may negatively impact our reputation. We may experience increased capital and operating costs to implement
increased security for our facilities and pipelines, such as additional physical facility and pipeline security, and additional security personnel. Third-party systems
on  which  we  rely  could  also  suffer  operational  system  failure.  Any  of  these  occurrences  could  disrupt  our  business,  result  in  potential  liability  or  reputational
damage or otherwise have an adverse effect on our financial results.

Terrorist attacks and the threat of terrorist attacks may adversely impact our results of operations.

Increased  security  measures  taken  by  us  as  a  precaution  against  possible  terrorist  attacks  have  resulted  in  increased  costs  to  our  business.  Uncertainty
surrounding  terrorist  attacks  in  the  U.S.  may  affect  our  operations  in  unpredictable  ways,  including  disruptions  of  crude  oil  supplies  or  storage  facilities,  and
markets for refined products, and the possibility that infrastructure facilities could be direct targets of, or indirect casualties of, an act of terror.

Risks Related to the SXE Transactions

We may be unable to obtain the regulatory clearances required to complete the SXE Merger or, in order to do so, we may be required to comply with material
restrictions or satisfy material conditions.

AMID and SXE received early termination of the applicable waiting period under the HSR Act on December 8, 2017. The Merger may still be reviewed under
antitrust statutes of other governmental authorities, including by state regulatory authorities such as the MPSC. The closing of the SXE Merger is subject to the
condition  that  there  is  no  law,  injunction,  judgment  or  ruling  by  a  governmental  authority  in  effect  enjoining,  restraining,  preventing  or  prohibiting  the  SXE
Merger. We can provide no assurance that all required regulatory clearances will be obtained. If a governmental authority asserts objections to the SXE Merger, we
may be required to divest assets in order to obtain antitrust clearance. There can be no assurance as to the cost, scope or impact of the actions that may be required
to obtain antitrust or other regulatory approval. If we take such actions, it could be detrimental to it or to the combined organization following the consummation of
the SXE Merger. Furthermore,  these actions could have the effect  of delaying  or preventing  completion  of the SXE Merger or imposing additional  costs on or
limiting the revenues or cash available for distribution of the combined organization following the consummation of the SXE Merger.

State attorneys general could seek to block or challenge the SXE Merger as they deem necessary or desirable in the public interest at any time, including after
completion of the transaction. In addition, in some circumstances, a third party could initiate a private action under antitrust laws challenging or seeking to enjoin
the SXE Merger, before or after it is completed. We may not prevail and may incur significant costs in defending or settling any action under the antitrust laws.

The MPSC requires  that when a company proposes a change of control of a certificate  of public convenience  and necessity  (“CPCN”), the company must
obtain  an  order  from  the  MPSC  approving  the  sale  and  transfer  of  the  CPCN.  Southcross  Mississippi  Industrial  Gas  Sales,  L.P.  (“Southcross  Mississippi”),  an
indirect subsidiary of SXE, has a CPCN that, subject to the approval of the MPSC, will be transferred in connection with the SXE Transactions. The MPSC could
decide not to issue an order authorizing the transfer of the CPCN. Moreover, there is no guarantee that, if granted, such order will be granted in a timely manner or
will be free from potentially burdensome conditions.

We may have difficulty attracting, motivating and retaining employees in light of the SXE Merger.

Uncertainty about the effect of the SXE Merger on our employees may have an adverse effect on the combined organization. This uncertainty may impair our
ability to attract, retain and motivate personnel until the SXE Merger is completed. Employee retention may be particularly challenging during the pendency of the
SXE  Merger,  as  employees  may  feel  uncertain  about  their  future  roles  with  the  combined  organization.  If  employees  depart  because  of  issues  relating  to  the
uncertainty  and  difficulty  of  integration  or  a  desire  not  to  become  employees  of  the  combined  organization,  the  combined  organization’s  ability  to  realize  the
anticipated benefits of the SXE Merger could be reduced.

43

We are subject to business uncertainties and contractual restrictions while the SXE Transactions are pending, which could adversely affect our business and
operations.

In connection with the pending SXE Transactions, it is possible that some customers, suppliers and other persons with whom we have business relationships
may  delay  or  defer  certain  business  decisions  or  might  decide  to  seek  to  terminate,  change  or  renegotiate  their  relationship  with  us  as  a  result  of  the  SXE
Transactions,  which  could  negatively  affect  our  revenues,  earnings  and  cash  available  for  distribution,  as  well  as  the  market  price  of  AMID  Common  Units,
regardless of whether the SXE Transactions completed.

Under the terms of the Merger Agreement, we are subject to certain restrictions on the conduct of our business prior to completing the SXE Merger, which
may  adversely  affect  our  ability  to  execute  certain  of  our  business  strategies.  Such  limitations  could  negatively  affect  our  business  and  operations  prior  to  the
completion of the SXE Merger.

Furthermore, the process of planning to integrate two businesses and organizations for the post-merger period can divert management attention and resources

and could ultimately have an adverse effect on each party.

However, we are permitted to engage in certain activities and transactions prior to completion of the SXE Merger, such as certain financings, incurrence of
indebtedness, issuances of equity, sales of assets and acquisitions. Any of these transactions could affect our current and future financial and operating results and
of the combined company.

The SXE Merger is subject to conditions, including certain conditions that may not be satisfied on a timely basis, if at all. Failure to complete the SXE Merger,
or significant delays in completing the SXE Merger, could negatively affect the trading price of AMID Common Units and our future business and financial
results.

The completion of the SXE Merger is subject to a number of conditions. The completion of the SXE Merger is not assured and is subject to risks, including the
risk that approval of the SXE Merger by SXE Unitholders or by governmental agencies is not obtained or that other closing conditions are not satisfied. If the SXE
Merger is not completed, or if there are significant delays in completing the SXE Merger, the trading price of AMID Common Units and our future business and
financial results could be negatively affected, and we will be subject to several risks, including the following:

•
•

•

we may be liable for damages to SXE under the terms and conditions of the Merger Agreement;
negative reactions from the financial markets, including declines in the price of AMID Common Units due to the fact that current prices may reflect a
market assumption that the SXE Merger will be completed; and
the attention of our management will have been diverted to the SXE Merger rather than our own operations and pursuit of other opportunities that
could have been beneficial to us.

The SXE Merger will not occur if the conditions to closing the SXE Contribution under the SXE Contribution Agreement, including the refinancing by us of
SXE’s indebtedness, are not satisfied and the closing of the SXE Contribution does not occur or if the SXE Contribution Agreement is otherwise terminated.

It is a condition to the closing of the SXE Merger under the terms of the SXE Merger Agreement that the SXE Contribution will have closed in accordance
with the SXE Contribution Agreement. Additionally, the SXE Merger Agreement will terminate automatically,  and the SXE Merger will not occur, if the SXE
Contribution  Agreement  is  terminated.  The  completion  of  the  SXE  Contribution  is  subject  to  a  number  of  conditions,  is  not  assured  and  is  subject  to  risks,
including the risk that approval by governmental agencies is not obtained or that other closing conditions are not satisfied. Additionally, if we have not obtained
sufficient financing to make the cash payments required to be made at the closing of the SXE Contribution, including for the refinancing of SXE’s indebtedness,
we may be required under certain circumstances to pay a reverse termination fee of $17 million to Holdings LP. We do not have in place committed financing
sufficient to make the payments at the closing of the SXE Contribution, and there can be no assurances that we will be able to obtain such financing on acceptable
terms or at all. Any such failure to obtain financing would likely result in the termination of the SXE Contribution Agreement and SXE Merger Agreement and the
failure to complete the SXE Merger.

The  number  of  outstanding  AMID  Common  Units  will  increase  as  a  result  of  the  SXE  Transactions,  which  could  make  it  more  difficult  for  us  to  pay  our
current level of quarterly distributions.

As  of  December  31,  2017,  there  were  approximately  52.7  million  AMID  Common  Units  outstanding.  We  estimate  that  we  will  issue  approximately  3.5
million AMID Common Units in connection with the SXE Merger and 13.6 million AMID Common Units in connection with the Contribution. Accordingly, the
aggregate dollar amount required to pay the current per unit quarterly distribution on all AMID Common Units will increase, which could increase the likelihood
that we will not have sufficient funds

44

to pay the current level of quarterly distributions to all AMID Common Unitholders. Using a $0.4125 per AMID Common Unit distribution (the distribution AMID
had declared with respect to the fourth fiscal quarter of 2017 paid on February 14, 2018 to holders of record as of February 7, 2018) the aggregate cash distribution
paid  to  AMID  Common  Unitholders  totaled  approximately  $21.7  million,  including  a  distribution  to  AMID  GP  in  respect  of  its  general  partner  interest.  The
combined pro forma AMID distribution with respect to the fourth fiscal quarter of 2017, had the SXE Merger been completed prior to such distribution, would
have resulted in $0.4125 per unit being distributed on approximately 69.8 million AMID Common Units, or a total of approximately $29.1 million including a
distribution of $0.3 million to AMID GP in respect of its general partner interest. As a result, we would have been required to distribute an additional $7.4 million
in order to maintain the distribution level of $0.4125 per AMID Common Unit payable with respect to the fourth fiscal quarter of 2017.

A substantial number of AMID Common Units and other securities convertible into, or exercisable for, AMID Common Units, will be issued in connection
with the SXE Transactions, which will dilute the ownership interests of existing unitholders, or may otherwise reduce the value of AMID Common Units.

Upon the terms and subject to the conditions set forth in the SXE Merger Agreement, at the Effective Time, each SXE Common Unit issued and outstanding
as of immediately prior to the Effective Time will be converted into the right to receive 0.160 of an AMID Common Unit. In addition, upon the terms and subject
to the conditions set forth in the Contribution Agreement, Holdings LP will receive AMID Common Units, Series E preferred units, which will be convertible into
AMID Common Units, and the Options, which will be exercisable into AMID Common Units. The issuance of AMID Common Units in the Transaction and the
issuance of AMID Common Units upon conversion of the Series E preferred units or the exercise of the Options issued in the SXE Contribution will dilute the
ownership interests of existing unitholders.

While Holdings LP has agreed not to sell any AMID Common Units, or any other securities convertible into, or exercisable for, AMID Common Units, for a
specified period set forth in the SXE Contribution Agreement, any sales, or expectation of sales, in the public market of AMID Common Units, including those
issuable upon the conversion of the Series E preferred units or the exercise of the Options, after the expiration of such period could adversely affect prevailing
market prices of AMID Common Units.

We will incur substantial transaction-related costs in connection with the SXE Transactions.

We expect to incur a  number of non-recurring transaction-related costs associated with completing the SXE Transactions, combining the operations of the
acquired organizations and achieving desired synergies. These fees and costs will be substantial. Non-recurring transaction costs include, but are not limited to,
fees paid to financial,  legal  and accounting  advisors, filing fees and printing costs. Additional unanticipated  costs may be incurred  in the integration  of the our
business with the business of SXE and the other businesses acquired from Holdings LP. There can be no assurance that the elimination of certain duplicative costs,
as well as the realization of other efficiencies related to the integration of the two businesses, will offset the incremental transaction-related costs over time.

Failure to successfully combine our business with the business of SXE and the other businesses acquired from Holdings LP in the expected time frame may
adversely affect the future results of the combined organization, and, consequently, the value of our common units.

The success  of the SXE Merger  will depend,  in part,  on our ability  to realize  the anticipated  benefits  and synergies  from  combining  our business with the
business of SXE and the other businesses acquired from Holdings LP. To realize these anticipated benefits, the businesses must be successfully combined. If the
combined  organization  is  not  able  to  achieve  these  objectives,  or  is  not  able  to  achieve  these  objectives  on  a  timely  basis,  the  anticipated  benefits  of  the  SXE
Merger may not be realized fully or at all. In addition, the actual integration may result in additional and unforeseen expenses, which could reduce the anticipated
benefits of the SXE Merger. These integration difficulties could result in declines in the market value of our common units.

Risks Related to Our Units, Partnership Structure and Ownership

As our common units are yield-oriented securities, increases in interest rates could adversely impact our unit price, our ability to issue equity or incur debt for
acquisitions or other purposes and our ability to make cash distributions at our intended levels.

Interest rates have increased recently and may continue to increase in the future. As a result, interest rates on future credit facilities and debt offerings could be
higher than current levels, causing our financing costs to increase accordingly. As with other yield-oriented securities, our unit price is impacted by our level of our
cash distributions and distribution yield. The distribution yield is often used by investors to compare and rank yield-oriented securities for investment decision-
making purposes. Therefore, changes in interest rates, either positive or negative, may affect the yield requirements of investors who invest in our units, and a

45

rising interest rate environment could have an adverse impact on our unit price, our ability to issue equity or incur debt for acquisitions or other purposes and our
ability to make cash distributions at our intended levels.

Affiliates  of  ArcLight  directly  own  our  General  Partner,  which  has  sole  responsibility  for  conducting  our  business  and  managing  our  operations.  These
affiliates elect all of the members of the board of our general partner. These affiliates and our general partner have conflicts of interest with us and limited
fiduciary duties, and they may favor their own interests to the detriment of us and our unitholders.

Affiliates of ArcLight and our general partner have the power to appoint all of the officers and directors of our general partner. The directors and officers of
our general partner have a fiduciary duty to manage our general partner in a manner that is beneficial to it, and have no duty to us or our common unitholders.
Conflicts of interest may arise between these affiliates and our general partner, on the one hand, and us and our noteholders, on the other hand. In resolving these
conflicts of interest, our general partner may favor its own interests and the interests of these affiliates over our interests and the interests of our noteholders. These
conflicts include the following situations, among others:

•

•

•

•

•
•
•

•

•
•

•

•

•
•

•
•
•
•

neither  our  Fifth  Amended  and  Restated  Agreement  of  Limited  Partnership  (as  amended,  the  “Partnership  Agreement")  nor  any  other  agreement
requires these affiliates of ArcLight to pursue a business strategy that favors us, and the officers and directors of these affiliates may have a fiduciary
duty to make these decisions in the best interests of these affiliates of ArcLight and their respective direct and indirect owners, respectively, which
may be contrary to our interests. These affiliates of ArcLight may choose to shift the focus of their investment and growth to areas not served by our
assets;
these affiliates of ArcLight, their respective direct and indirect owners and their respective affiliates are not limited in their ability to compete with us
and may offer business opportunities or sell midstream assets to third parties without first offering us the right to bid for them;
our general partner is allowed to take into account the interests of parties other than us in resolving conflicts of interest and exercising certain rights
under our Partnership Agreement, which has the effect of limiting its duty to our unitholders;
our Partnership Agreement replaces the fiduciary duties that would otherwise be owed by our general partner with contractual standards governing its
duties,  limits  our  general  partner’s  liabilities,  and  also  restricts  the  remedies  available  to  our  noteholders  for  actions  that,  without  the  limitations,
might constitute breaches of such fiduciary duty;
except in limited circumstances, our general partner has the power and authority to conduct our business without unitholder approval;
disputes may arise under our commercial agreements or acquisition agreements with these affiliates of ArcLight;
our general partner determines the amount and timing of asset purchases and sales, borrowings, issuance of additional partnership securities and the
creation, reduction or increase of reserves, each of which can affect the amount of cash that is distributed to our unitholders;
our general partner determines the amount and timing of any capital expenditures and whether a capital expenditure is classified as a maintenance
capital  expenditure,  which  reduces  operating  surplus,  or  an  expansion  capital  expenditure,  which  does  not  reduce  operating  surplus.  This
determination  can  affect  the  amount  of  cash  that  is  distributed  to  our  unitholders  and  to  our  general  partner  as  well  as  the  conversion  of  the
Convertible Preferred Units into common units;
our general partner determines which costs incurred by it are reimbursable by us;
our general partner may cause us to borrow funds in order to permit the payment of cash distributions, even if the purpose or effect of the borrowing
is to make a distribution on the Convertible Preferred Units, to make incentive distributions or to accelerate the expiration of a subordination period;
our Partnership Agreement permits us to classify up to $11.5 million as operating surplus, even if it is generated from asset sales, nonworking capital
borrowings or other sources that would otherwise constitute capital surplus. This cash may be used to fund distributions on our Convertible Preferred
Units or to our general partner in respect of the general partner interest or the incentive distribution rights;
our Partnership Agreement does not restrict our general partner from causing us to pay it or its affiliates for any services rendered to us or entering
into additional contractual arrangements with any of these entities on our behalf;
our general partner intends to limit its liability regarding our contractual and other obligations;
our general partner may exercise its right to call and purchase all of the common units not owned by it and its affiliates if they own more than 80% of
the common units;
our general partner controls the enforcement of the obligations that it and its affiliates owe to us;
our general partner decides whether to retain separate counsel, accountants or others to perform services for us;
our general partner may transfer its IDRs without unitholder approval;
our general partner may elect to cause us to issue common units to it in connection with a resetting of the target distribution levels related to our
general partner’s incentive distribution rights without the approval of the Conflicts

46

Committee  of  the  Board  of  Directors  of  our  general  partner  (“Conflicts  Committee”)  or  our  unitholders.  This  election  may  result  in  lower
distributions to our common unitholders in certain situations; and
although ArcLight has provided cash and other support for our liquidity in the past, it is under no obligation to do so in the future.

•

The affiliates of ArcLight that own our general partner are not limited in their ability to compete with us and are not obligated to offer us the opportunity to
acquire  additional  assets  or  businesses,  which  could  limit  our  ability  to  grow  and  could  adversely  affect  our  results  of  operations  and  cash  available  for
distribution to our unitholders.

The affiliates of ArcLight that own our general partner are not prohibited from owning assets or engaging in businesses that compete directly or indirectly with
us. In addition, in the future, affiliates of our general partner and the entities owned or controlled by affiliates of our general partner, including these affiliates of
ArcLight may acquire, construct or dispose of additional midstream or other assets and may be presented with new business opportunities, without any obligation
to offer us the opportunity to purchase or construct such assets or to engage in such business opportunities. Moreover, while these affiliates of ArcLight may offer
us  the  opportunity  to  buy  additional  assets  from  them,  they  are  under  no  contractual  obligation  to  do  so  and  we  are  unable  to  predict  whether  or  when  such
acquisitions might be completed. Although ArcLight has provided us with financial support in the past, it is under no obligation to do so in the future. This may
create actual and potential conflicts of interest between us and affiliates of our general partner, and result in less than favorable treatment of us and our unitholders.

The  New  York  Stock  Exchange  (“NYSE”)  does  not  require  a  publicly  traded  partnership  like  us  to  comply  with  certain  of  its  corporate  governance
requirements.

Our common units are listed on the NYSE. Because we are a publicly traded partnership, the NYSE does not require us to have a majority of independent
directors on our general partner’s board of directors or to establish a compensation committee or a nominating and corporate governance committee. Additionally,
any  future  issuance  of  additional  common  units  or  other  securities,  including  to  affiliates,  will  not  be  subject  to  the  NYSE’s  shareholder  approval  rules.
Accordingly, unitholders will not have the same protections afforded to certain corporations that are subject to all of the NYSE corporate governance requirements.

If you are not an eligible  holder, you may  not receive  distributions  or allocations of income  or loss on your common units and your common units will be
subject to redemption.

We  have  adopted  certain  requirements  regarding  those  investors  who  may  own  our  units.  Eligible  holders  are  U.S.  individuals  or  entities  subject  to
U.S. federal income taxation on the income generated by us or entities not subject to U.S. federal income taxation on the income generated by us, so long as all of
the  entity’s  owners  are  U.S.  individuals  or  entities  subject  to  such  taxation.  If  you  are  not  an  eligible  holder,  our  General  Partner  may  elect  not  to  make
distributions or allocate net income or loss on your units, and you run the risk of having your units redeemed by us at the lower of your purchase price for the units
and the then-current market price. The redemption price may be paid in cash or by delivery of a promissory note, as determined by our General Partner.

C ommon units held by persons who are non-taxpaying assignees will be subject to the possibility of redemption.

Our  Partnership  Agreement  gives  our  General  Partner  the  power  to  amend  the  agreement  to  avoid  any  adverse  effect  on  the  maximum  applicable  rates
chargeable  to  customers  by  us  under  FERC  regulations  or  to  reverse  an  adverse  determination  that  has  occurred  regarding  such  maximum  rate.  If  our  General
Partner  determines  that  our  not  being  treated  as  an  association  taxable  as  a  corporation  or  otherwise  taxable  as  an  entity  for  U.S.  federal  income  tax  purposes,
coupled with the tax status (or lack of proof thereof) of one or more of our limited partners, has, or is reasonably likely to have, a material adverse effect on the
maximum applicable rates chargeable to customers by us, then our General Partner may adopt such amendments to our Partnership Agreement as it determines are
necessary  or  advisable  to  obtain  proof  of  the  U.S.  federal  income  tax  status  of  our  limited  partners  (and  their  owners,  to  the  extent  relevant)  and  permit  us  to
redeem the units held by any person whose tax status has or is reasonably likely to have a material adverse effect on the maximum applicable rates or who fails to
comply with the procedures instituted by our General Partner to obtain proof of the U.S. federal income tax status.

Our Partnership Agreement requires that we distribute our available cash, which could limit our ability to grow and make acquisitions.

Our Partnership Agreement requires us to distribute our available cash to our unitholders. Accordingly, we will rely primarily upon external financing sources,
including commercial bank borrowings and the issuance of debt and equity securities, to fund our acquisitions and expansion capital expenditures. As a result, to
the extent we are unable to finance growth externally, our cash distribution policy will significantly impair our ability to grow.

47

In addition, because we intend to distribute our available cash, our growth may not be as fast as that of businesses that reinvest their available cash to expand
ongoing operations. To the extent we issue additional units in connection with any acquisitions or expansion capital expenditures, the payment of distributions on
those additional units may increase the risk that we will be unable to maintain or increase our per unit distribution level. There are no limitations in our Partnership
Agreement,  or  in  our  revolving  credit  facility,  on  our  ability  to  issue  additional  units,  including  units  ranking  senior  to  the  common  units.  The  incurrence  of
additional commercial borrowings or other indebtedness to finance our growth strategy would result in increased interest expense, which in turn may impact the
available cash that we have to distribute to our unitholders.

Our Partnership Agreement limits our General Partner’s fiduciary duties to us and the holders of our common units and restricts the remedies available to
holders of our common units for actions taken by our General Partner that might otherwise constitute breaches of fiduciary duty.

Our Partnership Agreement contains provisions that eliminate and replace the fiduciary duties to which our General Partner would otherwise be held by state

fiduciary duty law. For example, our Partnership Agreement:

•

•

•

•

provides that whenever our General Partner makes a determination or takes, or declines to take, any other action in its capacity as our General Partner, our
General Partner is required to make such determination, or take or decline to take such other action, in good faith, and will not be subject to any other or
different standard imposed by our Partnership Agreement, Delaware law, or any other law, rule or regulation, or at equity;
provides that our General Partner will not have any liability to us or our unitholders for decisions made in its capacity as a General Partner so long as such
decisions are made in good faith, meaning that it believed that the decision was in, or not opposed to, the best interest of our partnership;
provides  that  our  General  Partner  and  its  officers  and  directors  will  not  be  liable  for  monetary  damages  to  us,  our  limited  partners  or  their  assignees
resulting from any act or omission unless there has been a final and non-appealable judgment entered by a court of competent jurisdiction determining
that our General Partner or its officers and directors, as the case may be, acted in bad faith or engaged in fraud or willful misconduct or, in the case of a
criminal matter, acted with knowledge that the conduct was criminal; and
provides that our General Partner will not be in breach of its obligations under the Partnership Agreement or its fiduciary duties to us or our unitholders if
a transaction with an affiliate or the resolution of a conflict of interest is:

a.

b.

c.
d.

approved by the Conflicts Committee of the Board of Directors of our General Partner, although our General Partner is not obligated to seek
such approval;
approved  by  the  vote  of  a  majority  of  the  outstanding  common  units,  excluding  any  common  units  owned  by  our  General  Partner  and  its
affiliates;
on terms no less favorable to us than those generally being provided to or available from unrelated third parties; or
fair and reasonable to us, taking into account the totality of the relationships among the parties involved, including other transactions that may be
particularly favorable or advantageous to us.

In connection with a situation involving a transaction with an affiliate or a conflict of interest, any determination by our General Partner must be made in good
faith. If an affiliate transaction or the resolution of a conflict of interest is not approved by our common unitholders or the Conflicts Committee, and the Board of
Directors of our General Partner determines that the resolution or course of action taken with respect to the affiliate transaction or conflict of interest satisfies either
of the standards set forth in subclauses (c) and (d) above, then it will be presumed that, in making its decision, the board of directors acted in good faith, and in any
proceeding  brought  by  or  on  behalf  of  any  limited  partner  or  the  Partnership,  the  person  bringing  or  prosecuting  such  proceeding  will  have  the  burden  of
overcoming such presumption.

Our General Partner may elect to cause us to issue common units to it in connection with a resetting of the target distribution levels related to our General
Partner’s incentive distribution rights without the approval of the Conflicts Committee of our General Partner’s board or our unitholders. This election may
result in lower distributions to our common unitholders in certain situations.

Our General Partner has the right, at any time it has received incentive distributions exceeding the target distribution described in our Partnership Agreement
for each of the prior four consecutive fiscal quarters, to reset the initial target distribution levels at higher levels based on our cash distribution at the time of the
exercise of the reset election. Following a reset election by our General Partner, the minimum quarterly distribution will be reset to an amount equal to the average
cash  distribution  per  unit  for  the  two  fiscal  quarters  immediately  preceding  the  reset  election  (such  amount  is  referred  to  as  the  “reset  minimum  quarterly
distribution”), and the target distribution levels will be reset to correspondingly higher levels based on percentage increases above the reset minimum quarterly
distribution.

48

We  anticipate  that  our  General  Partner  would  exercise  this  reset  right  in  order  to  facilitate  acquisitions  or  internal  growth  projects  that  would  not  be
sufficiently  accretive  to  cash  distributions  per  common  unit  without  such  conversion;  however,  it  is  possible  that  our  General  Partner  could  exercise  this  reset
election at a time when we are experiencing declines in our aggregate cash distributions or at a time when our General Partner expects that we will experience
declines in our aggregate cash distributions in the foreseeable future. In such situations, our General Partner may be experiencing, or may expect to experience,
declines in the cash distributions it receives related to its incentive distribution rights and may therefore desire to be issued common units, which are entitled to
specified priorities with respect to our distributions and which therefore may be more advantageous for the General Partner to own in lieu of the right to receive
incentive distribution payments based on target distribution levels that are less certain to be achieved in the then current business environment. As a result, a reset
election may cause our common unitholders to experience dilution in the amount of cash distributions that they would have otherwise received had we not issued
common units to our General Partner in connection with resetting the target distribution levels related to our General Partner’s incentive distribution rights.

Holders of our common units have limited voting rights and are not entitled to elect our General Partner or its directors.

Unlike  the  holders  of  common  stock  in  a  corporation,  unitholders  have  only  limited  voting  rights  on  matters  affecting  our  business  and,  therefore,  limited
ability to influence management’s decisions regarding our business. Unitholders will have no right on an annual or ongoing basis to elect our General Partner or its
board of directors. The Board of Directors of our General Partner will be chosen by HPIP and AMID GP Holdings, LLC (“AMID GP Holdings”). Furthermore, if
the  unitholders  are  dissatisfied  with  the  performance  of  our  General  Partner,  they  will  have  little  ability  to  remove  our  General  Partner.  As  a  result  of  these
limitations, the price at which the common units will trade could be diminished because of the absence or reduction of a takeover premium in the trading price. Our
Partnership Agreement also contains provisions limiting the ability of unitholders to call meetings or to acquire information about our operations, as well as other
provisions limiting the unitholders’ ability to influence the manner or direction of management.

Even if holders of our common units are dissatisfied, they cannot currently remove our General Partner without its consent.

Our unitholders are unable to remove our General Partner without its consent because our General Partner and its affiliates own sufficient units to be able to
prevent its removal. The vote of the holders of at least 66 2/3% of all outstanding limited partner interests voting together as a single class is required to remove
our General Partner. As of December 31, 2017 , ArcLight indirectly held common units or convertible preferred units representing 48.60% of our then-outstanding
common units (on an as converted basis).

Our Partnership Agreement restricts the voting rights of unitholders owning 20% or more of our common units.

Unitholders’ voting rights are further restricted by a provision of our Partnership Agreement providing that any units held by a person that owns 20% or more
of any class of units then outstanding, other than our General Partner, its affiliates, their transferees and persons who acquired such units with the prior approval of
the Board of Directors of our General Partner, cannot vote on any matter.

Our General Partner interest or the control of our General Partner may be transferred to a third party without unitholder consent.

Our General Partner may transfer its General Partner interest to a third party in a merger or in a sale of all or substantially all of its assets without the consent
of  the  unitholders.  Furthermore,  our  Partnership  Agreement  does  not  restrict  the  ability  of  HPIP  or  AMID  GP  Holdings  to  transfer  all  or  a  portion  of  their
ownership interests in our General Partner to a third party. The new owner of our General Partner would then be in a position to replace the board of directors and
officers of our General Partner with its own designees and thereby exert significant control over the decisions made by the board of directors and officers.

We may issue additional units, including units that are senior to the common units and pari passu with our existing convertible preferred units, without your
approval, which would dilute your existing ownership interests.

Our  Partnership  Agreement  does  not  limit  the  number  of  additional  limited  partner  interests  that  we  may  issue  at  any  time  without  the  approval  of  our

unitholders. The issuance by us of additional common units or other equity securities of equal or senior rank will have the following effects:

•
•

our existing unitholders’ proportionate ownership interest in us will decrease;
the amount of cash available for distribution on each unit may decrease;

49

•

•
•
•

because of the convertible preferred units, the risk that a shortfall in the payment of the minimum quarterly distribution will be borne by our common
unitholders will increase;
the ratio of taxable income to distributions may increase;
the relative voting strength of each previously outstanding unit may be diminished; and
the market price of the common units may decline.

ArcLight may sell units in the public or private markets, and such sales could have an adverse impact on the trading price of the common units.

As of March 26, 2018, ArcLight held all of our Series A-1 Units, Series A-2 Units and Series C Units through its affiliates. The Series A-1, A-2 and C are all
convertible into common units at the election of ArcLight at any time.  The sale of these units and the common units owned directly and indirectly by ArcLight and
its affiliates could have an adverse impact on the price of the common units or on any trading market that may develop.

Our General Partner has a limited call right that may require you to sell your units at an undesirable time or price.

If at any time our General Partner and its affiliates own more than 80% of our common units, our General Partner will have the right, which it may assign to
any of its affiliates or to us, but not the obligation, to acquire all, but not less than all, of the common units held by unaffiliated persons at a price that is not less
than their then-current market price, as calculated pursuant to the terms of our Partnership Agreement. As a result, you may be required to sell your common units
at an undesirable time or price and may not receive any return on your investment. You may also incur a tax liability upon a sale of your units.

Your liability may not be limited if a court finds that unitholder action constitutes control of our business.

A  General  Partner  of  a  partnership  generally  has  unlimited  liability  for  the  obligations  of  the  Partnership,  except  for  those  contractual  obligations  of  the
Partnership  that  are  expressly  made  without  recourse  to  the  General  Partner.  Our  partnership  is  organized  under  Delaware  law,  and  we  conduct  business  in  a
number  of  other  states.  The  limitations  on  the  liability  of  holders  of  limited  partner  interests  for  the  obligations  of  a  limited  partnership  have  not  been  clearly
established in some of the other states in which we do business. You could be liable for any and all of our obligations as if you were a General Partner if a court or
government agency were to determine that:

•
•

we were conducting business in a state but had not complied with that particular state’s partnership statute; or
your right to act with other unitholders to remove or replace our General Partner, to approve some amendments to our Partnership Agreement or to
take other actions under our Partnership Agreement constitute “control” of our business.

Unitholders may have liability to repay distributions that were wrongfully distributed to them.

Under  certain  circumstances,  unitholders  may  have  to  repay  amounts  wrongfully  returned  or  distributed  to  them.  Under  Section  17-607  of  the  Delaware
Revised Uniform Limited  Partnership  Act, we may not make  a distribution  to you if the distribution  would cause  our liabilities  to exceed  the fair  value of our
assets. Delaware law provides that for a period of three years from the date of an impermissible distribution, limited partners who received the distribution and who
knew at the time of the distribution that it violated Delaware law will be liable to the limited partnership for the distribution amount. Substituted limited partners
are liable both for the obligations of the assignor to make contributions to the Partnership that were known to the substituted limited partner at the time it became a
limited partner  and for those obligations  that were unknown if the liabilities  could have been determined from the Partnership Agreement. Neither liabilities  to
partners  on  account  of  their  partnership  interest  nor  liabilities  that  are  non-recourse  to  the  Partnership  are  counted  for  purposes  of  determining  whether  a
distribution is permitted.

If we are deemed an “investment company” under the Investment Company Act of 1940, it would adversely affect the price of our common units and could
have a material adverse effect on our business.

Our assets include 35.7% non-operated interest in Delta House Class A Units, a 16.7% non-operated interest in Tri- States, a 25.3% non-operated interest in
Wilprise, a non-operated interest in Mesquite and a 26.3% non-operated interest in Pinto, any of which may be deemed to be an “investment security” within the
meaning of the Investment Company Act of 1940, as amended (the “Investment Company Act”). In the future, we may acquire additional minority owned interests
that could be deemed “investment securities.” If a sufficient amount of our assets are deemed to be “investment securities” within the meaning of the Investment
Company Act, we would either have to register as an investment company under the Investment Company Act, obtain exemptive relief from the SEC or modify
our organizational  structure or our contract rights to fall outside the definition of an investment company. Registering as an investment company could, among
other things, materially limit our ability to engage

50

transactions with affiliates, including the purchase and sale of certain securities or other property to or from our affiliates, restrict our ability to borrow funds or
engage in other transactions involving leverage and require us to add additional directors who are independent of us or our affiliates. The occurrence of some or all
of these  events  may have a material  adverse  effect  on our business. Moreover, treatment  of us as an investment  company  would prevent  our qualification  as a
partnership for U.S. federal income tax purposes in which case we would be treated as a corporation for U.S. federal income tax purposes, and be subject to U.S.
federal income tax at the corporate tax rate, significantly reducing the cash available for distributions.

Additionally, distributions to our unitholders would be taxed again as corporate distributions and none of our income, gains, losses or deductions would flow

through to our unitholders.

Additionally,  as  a  result  of  our  desire  to  avoid  having  to  register  as  an  investment  company  under  the  Investment  Company  Act,  we  may  have  to  forego
potential  future  acquisitions  of  interests  in  companies  that  may  be  deemed  to  be  investment  securities  within  the  meaning  of  the  Investment  Company  Act  or
dispose of our current interests in any of our assets that are deemed to be “investment securities.”

Tax Risks to Common Unitholders

Our tax treatment depends on our status as a partnership for U.S. federal income tax purposes, as well as our not being subject to a material amount of entity-
level taxation by individual states. If the Internal Revenue Service (“IRS”) were to treat us as a corporation for U.S. federal income tax purposes or we become
subject  to  material  additional  amounts  of  entity-level  taxation  for  state  tax  purposes,  then  our  cash  available  for  distribution  to  the  unitholders  would  be
substantially reduced.

The anticipated after-tax economic benefit of an investment in the common units depends largely on our being treated as a partnership for U.S. federal income

tax purposes.

Despite the fact that we are a limited partnership under Delaware law, it is possible in certain circumstances for a publicly traded partnership such as ours to be
treated as a corporation for U.S. federal income tax purposes. Although we do not believe based upon our current operations that we are so treated, the IRS could
disagree with the positions we take or a change in our business (or a change in current law) could cause us to be treated as a corporation for U.S. federal income tax
purposes or otherwise subject us to taxation as an entity.

If we were treated as a corporation for U.S. federal income tax purposes, we would pay U.S. federal income tax on our taxable income at the corporate tax
rate, which is currently a maximum of 21%, and would likely pay state income tax at varying rates. Distributions to a unitholder would generally be taxed again as
corporate dividends (to the extent of our current and accumulated earnings and profits), and no income, gains, losses, deductions, or credits would flow through to
the  unitholder.  Because  a  tax  would  be  imposed  upon  us  as  a  corporation,  our  cash  available  for  distribution  to  unitholders  would  be  substantially  reduced.
Therefore,  treatment  of us as a corporation  for U.S. federal  income tax purposes would result in a material  reduction  in the anticipated  cash flow and after-tax
return to the unitholders, likely causing a substantial reduction in the value of our common units.

Our Partnership Agreement provides that, if a law is enacted or existing law is modified or interpreted in a manner that subjects us to taxation as a corporation
or  otherwise  subjects  us  to  entity-level  taxation  for  federal,  state  or  local  income  tax  purposes,  the  minimum  quarterly  distribution  amount  and  the  target
distribution amounts may be adjusted to reflect the impact of that law on us.

The  tax  treatment  of  publicly  traded  partnerships  or  an  investment  in  our  common  units  could  be  subject  to  potential  legislative,  judicial  or  administrative
changes and differing interpretations, possibly on a retroactive basis.

The  present  U.S.  federal  income  tax  treatment  of  publicly  traded  partnerships,  including  us,  or  an  investment  in  our  common  units  may  be  modified  by
administrative, legislative or judicial interpretation at any time. From time to time, members of the U.S. Congress propose and consider such substantive changes
to the existing U.S. federal income tax laws that affect publicly traded partnerships. If successful, such proposals or other similar proposals could eliminate the
qualifying  income exception  to the treatment  of all publicly  traded partnerships  as corporations  upon which we rely for our treatment  as a partnership  for U.S.
federal income tax purposes. We are unable to predict whether any of these changes or other proposals will ultimately be enacted, but it is possible that a change in
law could affect us and may, if enacted, be applied retroactively. Any such changes could negatively impact the value of an investment in our common units.

On  January  24,  2017,  the  U.S.  Treasury  Department  and  the  IRS  published  final  regulations  (the  “Final  Regulations”)  regarding  qualifying  income  under

Section 7704(d)(1)(E) of the Code. We believe the income that we treat as qualifying satisfies the

51

requirements  under  these  regulations.  However,  there  are  no  assurances  that  the  regulations  will  not  be  revised  to  take  a  position  that  is  contrary  to  our
interpretation of current law.

Because of widespread state budget deficits and other reasons, several states are evaluating ways to subject partnerships to entity-level taxation through the
imposition of state income, franchise and other forms of taxation. For example, we are required to pay the State of Texas a margin tax that is assessed at 0.75% of
taxable margin apportioned to Texas. Imposition of such a tax on us by any state will reduce the cash available for distribution to unitholders. The Partnership
Agreement provides that if a law is enacted or existing law is modified or interpreted in a manner that subjects us to taxation as a corporation or otherwise subjects
us  to  entity-level  taxation  for  federal,  state  or  local  income  tax  purposes,  the  minimum  quarterly  distribution  amount  and  the  target  distribution  levels  will  be
adjusted to reflect the impact of that law on us.

Compliance with and changes in tax laws could adversely affect our performance.

We are subject to extensive tax laws and regulations, including federal and state income tax laws and transactional tax laws such as excise, sales/use, payroll,
franchise and ad valorem tax laws. New tax laws and regulations and changes in existing tax laws and regulations are continuously being enacted that could result
in increased tax expenditures in the future. Further, taxing authorities may change their application of existing taxes, so that additional entities or transactions may
become subject to an existing tax. Many of these tax liabilities are subject to audits by the respective taxing authority. These audits may result in additional tax
payments, as well as interest and penalties. The costs of these audits are borne indirectly by the unitholders and our General Partner because such costs reduce our
cash available for distribution.

If the IRS contests the U.S. federal income tax positions we take, the market for our common units may be adversely impacted, and the cost of any IRS contest
will reduce our cash available for distribution to the unitholders.

We have not requested a ruling from the IRS with respect to our treatment as a partnership for U.S. federal income tax purposes. The IRS may adopt positions
that differ from the conclusions of our counsel expressed in a prospectus or from the positions we take, and the IRS’s positions may ultimately be sustained. It may
be necessary to resort to administrative or court proceedings to sustain some or all of our counsel’s conclusions or the positions we take. A court may not agree
with some or all of our counsel’s conclusions or positions we take. Any contest with the IRS, and the outcome of any such contest, may increase a unitholder’s tax
liability and result in adjustment to items unrelated to us and could materially and adversely impact the market for our common units and the price at which they
trade. In addition, our costs of any contest with the IRS will be borne indirectly by the unitholders and our General Partner because such costs will reduce our cash
available for distribution.

If the IRS makes audit adjustments to our income tax returns for tax years beginning after December 31, 2017, it may collect any resulting taxes (including
any applicable penalties and interest) directly from us, in which case our cash available for distribution to our unitholders might be substantially reduced.

If the IRS makes audit adjustments to our income tax returns for tax years beginning after December 31, 2017, it may collect any resulting taxes (including
any  applicable  penalties  and  interest)  directly  from  us.  Although  our  General  Partner  may  elect  to  have  our  unitholders  and  former  unitholders  take  such  audit
adjustments into account and pay any resulting taxes (including applicable penalties or interest) in accordance with their interests in us during the tax year under
audit, there can be no assurance that such election will be practical, permissible or effective in all circumstances. If we are unable to have the unitholders take such
audit adjustment into account in accordance with their interests during the taxable year under audit, the current unitholders may bear some or all of the tax liability
resulting from such audit adjustment, even if such unitholders did not own units during the taxable year under audit. If we are required to make payments of taxes,
penalties and interest resulting from audit adjustments, our cash available for distribution to our unitholders might be substantially reduced.

The unitholders' share of our income will be taxable to them for U.S. federal income tax purposes even if the unitholders do not receive any cash distributions
from us.

Because a unitholder will be treated as a partner to whom we will allocate taxable income, which could be different in amount than the cash we distribute, a
unitholder's allocable share of our taxable income will be taxable to it, which may require the payment of U.S. federal income taxes and, in some cases, state and
local income taxes on its share of our taxable income even if it receives no cash distributions from us. The unitholders may not receive cash distributions from us
equal to their share of our taxable income or even equal to the tax liability that results from that income.

Certain actions that we may take, such as issuing additional units, may increase the U.S. federal income tax liability of unitholders.

52

In  the  event  we  issue  additional  units  or  engage  in  certain  other  transactions  in  the  future,  the  allocable  share  of  nonrecourse  liabilities  allocated  to  the
unitholders will be recalculated to take into account our issuance of any additional units. Any reduction in a unitholder's share of our nonrecourse liabilities will be
treated as a distribution of cash to that unitholder and will result in a corresponding tax basis reduction in a unitholder's units. A deemed cash distribution may,
under certain circumstances, result in the recognition of taxable gain by a unitholder, to the extent that the deemed cash distribution exceeds such unitholder's tax
basis in its units.

In  addition,  the  U.S.  federal  income  tax  liability  of  a  unitholder  could  be  increased  if  we  dispose  of  assets  or  make  a  future  offering  of  units  and  use  the
proceeds in a manner that does not produce substantial additional deductions, such as to repay indebtedness currently outstanding or to acquire property that is not
eligible  for  depreciation  or  amortization  for  U.S.  federal  income  tax  purposes  or  that  is  depreciable  or  amortizable  at  a  rate  significantly  slower  than  the  rate
currently applicable to the our assets.

Unitholders may be subject to limitations on their ability to deduct interest expense we incur.

Our ability to deduct business interest expense will be limited for U.S. federal income tax purposes to an amount equal to the sum of (i) our business interest
income during the taxable year and (ii) 30% of our adjusted taxable income for such taxable year. For the purposes of this limitation, adjusted taxable income is
computed  without  regard  to  any  business  interest  expense  or  business  interest  income,  and  in  the  case  of  taxable  years  beginning  before  January  1,  2022,  any
deduction allowable for depreciation, amortization, or depletion. If we are not entitled to fully deduct our business interest in any taxable year, such excess business
interest expense will be allocated to each unitholder as excess business interest and can be carried forward by the unitholder to successive taxable years and used to
offset any excess taxable income allocated by us to such unitholder. Any excess business interest expense allocated to a unitholder will reduce such unitholder’s
tax basis in its partnership interest in the year of the allocation even if the expense does not give rise to a deduction to the unitholder in that year. Immediately prior
to a disposition of its shares, a unitholder’s tax basis will be increased by the amount by which such basis reduction exceeds the excess interest expense that has
been deducted by such unitholder.

There are limits on the deductibility of losses that may adversely affect unitholders.

In the case of taxpayers subject to the passive loss rules (generally, individuals, closely-held corporations and regulated investment companies), any losses
generated by us will only be available to offset our future income and cannot be used to offset income from other activities, including other passive activities or
investments.  Unused  losses  may  be  deducted  when  the  unitholder  disposes  of  the  unitholder’s  entire  investment  in  us  in  a  fully  taxable  transaction  with  an
unrelated party. A unitholder’s share of our net passive income may be offset by unused losses from us carried over from prior years, but not by losses from other
passive activities, including losses from other publicly traded partnerships.

Further, in addition to the other limitations described above, non-corporate taxpayers may only deduct business losses up the gross income or gain attributable
to such trade or business plus $250,000 ($500,000 for unitholders filing jointly). Amounts that may not be deducted in a taxable year may be carried forward into
the following taxable year. This limitation shall be applied after the passive loss limitations and, unless amended, applies only to taxable years beginning prior to
December 31, 2025.

Tax gain or loss on the disposition of our common units could be more or less than expected.

If a unitholder sells its common units, the unitholder will recognize a gain or loss equal to the difference between the amount realized and the unitholder's tax
basis in those common units. Because distributions to a unitholder in excess of the total net taxable income allocated to the unitholder decrease the unitholder's tax
basis in the unitholder's common units, the amount, if any, of such prior excess distributions with respect to the units sold will, in effect, become taxable income to
the unitholder if the unitholder sells the common units at a price greater than the unitholder's tax basis in those common units, even if the price received by the
unitholder  is  less  than  the  original  cost.  Furthermore,  a  substantial  portion  of  the  amount  realized  on  any  sale  of  a  unitholder's  common  units,  whether  or  not
representing gain, may be taxed as ordinary income due to potential recapture items, including depreciation recapture. In addition, because the amount realized
includes a unitholder's share of our nonrecourse liabilities, if the unitholder sells its common units, the unitholder may incur a tax liability in excess of the amount
of cash the unitholder receives from the sale.

Tax-exempt entities and non-U.S. persons face unique tax issues from owning our common units that may result in adverse tax consequences to them.

Investment in common units by tax-exempt entities, such as individual retirement accounts, or IRAs, other retirement plans and non-U.S. persons raises issues

unique to them. For example, virtually all of our income allocated to organizations that are

53

exempt  from  U.S.  federal  income  tax,  including  IRAs  and  other  retirement  plans,  will  be  unrelated  business  taxable  income,  which  may  be  taxable  to  them.
Further,  with  respect  to  taxable  years  beginning  after  December  31,  2017,  a  tax-exempt  entity  with  more  than  one  unrelated  trade  or  business  (including  by
attribution from investment in a partnership such as ours that is engaged in one or more unrelated trade or business) is required to compute the unrelated business
taxable  income  of  such  tax-exempt  entity  separately  with  respect  to  each  such  trade  or  business  (including  for  purposes  of  determining  any  net  operating  loss
deduction). As a result, for years beginning after December 31, 2017, it may not be possible for tax-exempt entities to utilize losses from an investment in our
partnership to offset unrelated business taxable income from another unrelated trade or business and vice versa. Tax-exempt entities should consult a tax advisor
before investing in our common units.

Non-U.S. persons are generally taxed and subject to U.S. federal income tax filing requirements on income effectively connected with a U.S. trade or business.
Income  allocated  to  our  unitholders  and,  under  recently  enacted  legislation,  any  gain  from  the  sale  of  our  units  will  generally  be  considered  to  be  “effectively
connected” with a U.S. trade or business. As a result, distributions to a non-U.S. unitholder will be subject to withholding at the highest applicable effective tax
rate, and a non-U.S. unitholder who sells or otherwise disposes of its interest will be subject to U.S. federal income tax on gain realized from the sale or disposition
of that unit to the extent the gain is effectively connected with a U.S. trade or business of the non-U.S. unitholder.

Recently  enacted  legislation  also  imposes  a  federal  income  tax  withholding  obligation  of  10%  of  the  amount  realized  upon  a  non-U.S.  person’s  sale  or
exchange  of  an  interest  in  a  partnership  that  is  engaged  in  a  U.S.  trade  or  business.  However,  due  to  challenges  of  administering  a  withholding  obligation
applicable to open market trading and other complications, the application of this withholding rule to dispositions of publicly traded partnership interests has been
temporarily suspended by the IRS until regulations or other guidance that resolves the challenges have been issued. It is not clear if or when such regulations or
guidance will be issued. Non-U.S. persons should consult a tax advisor before investing in our common units.

We treat each purchaser of our common units as having the same tax benefits without regard to the actual common units purchased. The IRS may challenge
this treatment, which could adversely affect the value of the common units.

Because we cannot match transferors and transferees of common units and because of other reasons, we have adopted depreciation and amortization positions
that may not conform to all aspects of existing Treasury regulations. A successful IRS challenge to those positions could adversely affect the amount of tax benefits
available to the unitholders. It also could affect the timing of these tax benefits or the amount of gain from the sale of common units and could have a negative
impact on the value of our common units or result in audit adjustments to the unitholders' tax returns.

We prorate our items of income, gain, loss and deduction for U.S. federal income tax purposes between transferors and transferees of our units each month
based  upon  the  ownership  of  our  units  on  the  first  day  of  each  month,  instead  of  on  the  basis  of  the  date  a  particular  unit  is  transferred.  The  IRS  may
challenge this treatment, which could change the allocation of items of income, gain, loss and deduction among the unitholders.

We prorate our items of income, gain, loss and deduction for U.S. federal income tax purposes between transferors and transferees of our units each month
based upon the ownership of our units on the first day of each month, instead of on the basis of the date a particular unit is transferred. Treasury recently adopted
final regulations that provide a safe harbor pursuant to which publicly traded partnerships may use a similar monthly simplifying convention to allocate tax items
among transferor and transferee unitholders to ours. These regulations apply to certain publicly-traded partnerships, including us, for taxable years beginning on or
after August 3, 2015. However, these regulations do not specifically authorize the use of the proration method we have adopted. If the IRS were to challenge our
proration method, we may be required to change the allocation of items of income, gain, loss and deduction among the unitholders.

We have adopted certain valuation methodologies for tax purposes that may result in a shift of income, gain, loss and deduction between our General Partner
and the unitholders. The IRS may challenge this treatment, which could adversely affect the value of the common units.

When we issue additional units or engage in certain other transactions, we determine the fair market value of our assets and allocate any unrealized gain or
loss attributable to our assets to the capital accounts of our unitholders and the General Partner. Our methodology may be viewed as understating the value of our
assets. In that case, there may be a shift of income, gain, loss and deduction between certain unitholders and our General Partner, which may be unfavorable to
such unitholders. Moreover, subsequent purchasers of common units may have a greater portion of the Code Section 743(b) adjustment allocated to our tangible
assets  and  a  lesser  portion  allocated  to  our  intangible  assets.  The  IRS  may  challenge  our  valuation  methods,  or  our  allocation  of  the  Code  Section  743(b)
adjustment attributable to our tangible and intangible assets, and allocations of income, gain, loss and deduction between our General Partner and certain of the
unitholders.

54

A successful IRS challenge to these methods or allocations could adversely affect the amount of taxable income or loss being allocated to the unitholders. It
also could affect the amount of gain from the unitholders' sale of common units and could have a negative impact on the value of the common units or result in
audit adjustments to the unitholders’ tax returns without the benefit of additional deductions.

Unitholders may be subject to state and local taxes and return filing requirements in states and jurisdictions where they do not reside as a result of investing in
our units.

In addition to U.S. federal income taxes, unitholders may be subject to other taxes, including foreign, state and local taxes, unincorporated business taxes and
estate, inheritance or intangible taxes that are imposed by the various jurisdictions in which we do business or own property, even if the unitholders do not live in
any of those jurisdictions. Unitholders may be required to file foreign, state and local income tax returns and pay state and local income taxes in some or all of
these jurisdictions. Further, unitholders may be subject to penalties for failure to comply with those requirements. As we make acquisitions or expand our business,
we  may  own  assets  or  do  business  in  additional  states  that  impose  a  personal  income  tax  or  an  entity  level  tax.  It  is  each  unitholder's  responsibility  to  file  all
U.S. federal, foreign, state, local and non-U.S. tax returns.

Some  of  the  states  in  which  we  do business  or  own property  may  require  us to,  or  we  may  elect  to,  withhold a  percentage  of  income  from  amounts  to  be
distributed to a unitholder who is not a resident of the state. Withholding, the amount of which may be greater or less than a particular unit holder's income tax
liability to the state, generally does not relieve the nonresident unitholder from the obligation to file an income tax return. Amounts withheld may be treated as if
distributed to unitholders for purposes of determining the amounts distributed by us.

Item 3. Legal Proceedings

On  December  18,  2015,  Vintage  Assets,  Inc.,  et  al.  (“Vintage”),  filed  a  lawsuit  in  the  Judicial  District  Court  in  Plaquemines  Parish,  Louisiana  alleging  that
defendants Southern Natural Gas Company, L.L.C. (“SNG”) and Tennessee Gas Pipeline Company, L.L.C. failed to maintain the canals in which their pipelines
were  laid  and  failed  to  maintain  the  associated  banks  causing  erosion,  ecological  damage,  and  unspecified  monetary  damages,  and  trespassed  on  Plaintiffs’
property. The case was removed to the United States District Court for the Eastern District of Louisiana on January 27, 2016. Our subsidiaries High Point Gas
Transmission, L.L.C. (“HPGT”) and High Point Gas Gathering, L.L.C. (“HPGG”) are successors in interest to SNG with regard to certain of the property interests
at  issue  in  this  proceeding.  On  October  24,  2016,  HPGT  and  HPGG  were  added  to  the  lawsuit  as  co-defendants.  Plaintiffs  subsequently  demanded  either
restoration of their property or, alternatively, $44.0 million in damages (the plaintiff’s alleged estimated cost of restoration). A bench trial was held in September
2017,  but  a  judgment  has  not  been  rendered.  The  purchase  and  sale  agreements  pursuant  to  which  HPGG  and  HPGT  acquired  its  property  interests  contain
provisions pursuant to which the sellers agreed to indemnify HPGT or HPGG, as applicable, from all liabilities, including attorney’s fees, attributable to the period
prior to such acquisition.

While the ultimate impact of any proceedings cannot be predicted with certainty, our management believes that the resolution of any of our pending proceedings
will not have a material adverse effect on our financial condition or results of operations.

As of March 26, 2018 , there were 127 unitholders of record of our common units. This number does not include unitholders whose units are held in trust by other
entities. The actual number of unitholders is greater than the number of holders of record. As of March 26, 2018 we have approximately 11,009,729 Series A Units,
9,241,642 Series C Units and 964,563 General Partner units. Our General Partner and its affiliates receive quarterly distributions on the General Partner units only
after the requisite distributions have been paid on the common units, Series A Units and Series C Units. If the SXE Transactions are consummated, we will issue a
new class of preferred units called Series E preferred units at the closing of the SXE Transactions pursuant to the SXE Transaction Agreements.

Our Distribution Policy

Our Partnership Agreement requires us to distribute all of our available cash quarterly. Our cash distribution policy reflects our belief that our unitholders will be
better served if we distribute rather than retain our available cash. Generally, our available cash is the sum of our i) cash on hand at the end of a quarter after the
payment of our expenses and the establishment of cash reserves and ii) cash on hand resulting from working capital borrowings made after the end of the quarter.
We pay quarterly a cash dividend to those unitholders of record on the applicable record date, as determined by the General Partner.

Our  cash  distribution  policy,  as  expressed  in  our  Partnership  Agreement,  may  not  be  modified  or  repealed  without  amending  our  Partnership  Agreement.  The
actual amount of our cash distributions for any quarter is subject to fluctuations based on the amount of cash we generate from our business and the amount of
reserves our General Partner establishes in accordance with our Partnership Agreement as described above. We will pay our distributions on or about the 15th of
each February, May, August and November to holders of record on or about the 5th of each such month. If the distribution date does not fall on a business day, we
will make the distribution on the business day immediately preceding the indicated distribution date.

Our  General  Partner's  initial  2.0%  interest  in  distributions  has  been  reduced  to  1.32% as  of  December  31, 2017  due  to  the  issuance  of additional  units  and  the
General Partner has not contributed a proportionate amount of capital to us to maintain its initial 2.0% General Partner notional interest.

Series A Units

Distributions on Series A Units can be made with paid-in-kind Series A Units, cash or a combination thereof, at the discretion of the Board of Directors, which
began since the distribution for the three months ended June 30, 2014. At December 31, 2017 , we accrued $4.4 million of contractual paid-in-kind distributions on
the Series A Units which were distributed on February 14, 2018.

Series C Units

Distributions on Series C Units can be made with paid-in-kind Series C Units, cash or a combination thereof, at the discretion of the Board of Directors and upon
the consent of the holders of the Series C Units. At December 31, 2017 , we accrued $3.7 million of contractual paid-in-kind distributions on the Series C Units
which were distributed on February 14, 2018.

Item 6. Selected Historical Financial and Operating Data

The following table presents selected historical consolidated financial and operating data for the periods and as of the dates indicated. We derived this information
from our historical consolidated financial statements and accompanying notes. This information should be read together with, and is qualified in its entirety, by
reference to those consolidated financial statements and notes, which for the years 2017 , 2016 , and 2015 begin on page F-1 to this Annual Report.

On  March  8,  2017  we  acquired  JPE  in  a  unit-for-unit  exchange.  As  both  the  Partnership  and  JPE  were  controlled  by  ArcLight,  the  acquisition  represents  a
transaction among entities under common control and is accounted for as a common control transaction in a manner similar to a pooling of interests. Although the
Partnership is the legal acquirer, JPE is considered to be the acquirer for accounting purposes as ArcLight obtained control of JPE before it obtained control the
Partnership. The following selected historical financial information represent JPE’s historical cost basis financial information which has been recast to reflect the
acquisition of the Partnership at ArcLight’s historical cost basis effective April 15, 2013, the date on which ArcLight obtained control of the Partnership.

On September 1, 2017, the Partnership completed the disposition of its Propane Business. Through the transaction, the Partnership divested 100% of the Propane

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

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with the audited consolidated financial statements and
the related notes thereto included elsewhere in this Annual Report. This discussion contains forward-looking statements that reflect management’s current views with respect to
future events and financial performance. Our actual results may differ materially from those anticipated in these forward-looking statements or as a result of certain factors
such as those set forth below under the caption "Cautionary Statement About Forward-Looking Statements."

Overview

We are a growth-oriented Delaware limited partnership that was formed in August 2009 to own, operate, develop and acquire a diversified portfolio of midstream
energy assets. We provide critical midstream infrastructure that links producers of natural gas, crude oil, NGLs, condensate and specialty chemicals to numerous
intermediate and end-use markets. Through our five reportable segments, (i) gas gathering and processing services, (ii) liquid pipelines and services, (iii) natural
gas  transportation  services,  (iv)  offshore  pipelines  and  services  and  (v)  terminalling  services,  we  engage  in  the  business  of  gathering,  treating,  processing,  and
transporting natural gas; gathering, transporting, storing, treating and fractionating NGLs; gathering, storing and transporting crude oil and condensates and storing
specialty  chemical  products  and  refined  products.  As  of  September  1,  2017,  as  a  result  of  the  disposition  of  the  Propane  Business  described  in  in  Note  4  -
Discontinued Operations , in Part II, Item 8 of this Annual Report, we have eliminated the Propane Marketing Services segment.

60

Our primary assets are strategically located in some of the most prolific onshore and offshore producing regions and key demand markets in the United States. Our
gathering and processing assets are primarily located in (i) the Permian Basin of West Texas, (ii) the Cotton Valley/Haynesville Shale of East Texas, (iii) the Eagle
Ford Shale of South Texas, (iv) the Bakken Shale of North Dakota, and (v) offshore in the Gulf of Mexico. Our liquid pipelines, natural gas transportation and
offshore pipelines and terminal assets are located in prolific producing regions and key demand markets in Alabama, Louisiana, Mississippi, North Dakota, Texas,
Tennessee and in the Port of New Orleans in Louisiana and the Port of Brunswick in Georgia. Additionally, we operate a fleet of NGL gathering and transportation
trucks  in the Eagle Ford shale and the Permian Basin. See Recent Developments in Part I, Item 1 of this Annual Report for more information about our recent
acquisitions and dispositions.

We own or have ownership interests in more than 5,100 miles of onshore and offshore natural gas, crude oil, NGL and saltwater pipelines across 17 gathering
systems,  seven  interstate  pipelines  and  nine  intrastate  pipelines;  eight  natural  gas  processing  plants;  four  fractionation  facilities;  an  offshore  semisubmersible
floating  production  system  with  nameplate  processing  capacity  of  90  MBbl/d  of  crude  oil  and  220  MMcf/d  of  natural  gas;  six  marine  terminal  sites  with
approximately  6.7  MMBbls  of  above-ground  aggregate  storage  capacity  for  petroleum  products,  distillates,  chemicals  and  agricultural  products;  and  90
transportation trucks and a total trailer fleet of 130, of which 35 are LPG trailers and 95 are crude oil trailers.

A portion of our cash flow is derived from our investments in unconsolidated affiliates, including a 66.67% operated interest in Destin, a natural gas pipeline; a
66.7%  operated  interest  in  Okeanos,  a  natural  gas  pipeline;  a  35.7%  non-operated  interest  in  the  Class  A  units  and  common  units  of  Delta  House,  a  floating
production system platform and related pipeline infrastructure; a 25.3% non-operated interest in Wilprise, an NGL pipeline; a 16.7% non-operated interest in Tri-
States,  an  NGL  pipeline;  and  up  to  August  8,  2017,  prior  our  acquisition  of  Panther,  a  66.7%  interest  in  MPOG,  a  crude  oil  gathering  and  processing  system.
Subsequent to the acquisition of Panther, we consolidated and wholly owned MPOG.

Financial Highlights

Financial highlights during the year ended December 31, 2017, include the following:

• Net loss attributable to the Partnership increased to $223.0 million, or an increase of 334.6%, as compared to net loss of $51.3 million in 2016, which
was  primarily  due  to  a  combination  of  an  increase  in  operating  loss  of  $233.9  million,  including  non  cash  impairment  charges  of  $194.6  million,  and
increased interest expense of $45.0 million associated with higher average debt balances from our growth initiatives  as well as higher average interest
costs, offset by the net gain on disposition of the Propane Business of $47.4 million and the gain of $36.0 million related to the MPOG acquisition. The
impairment charges of $194.6 million, of which $116.6 million was associated with our property, plant and equipment and intangible assets associated
with certain non core assets in our Gas Gathering and Processing Services segment and our Liquid Pipelines and Services segment and approximately
$78.0 million in goodwill, associated with certain assets in our Liquid Pipelines and Services segment. See Note 9 - Property, Plant and Equipment and
Note 10 - Goodwill and Intangible Assets , Net in Part II, Item 8 of this Annual Report for more information.

• Earnings in unconsolidated affiliates were $63.1 million, an increase of $22.9 million as compared to $40.2 million for the same period in 2016, which
was  primarily  due  to  an  increase  of  $13.2  million  due  to  the  incremental  ownership  in  Delta  House  in  the  fourth  quarter  of  2016  and  our  subsequent
increases in ownership in November 2017, $5.4 million from Destin as a result of twelve months of ownership reflected in 2017 as compared to eight
months of ownership in 2016, as well as higher volumes on our Okeanos system for $4.0 million. Additionally, there was a $3.0 million increase driven
by increasing volumes on Tri-States and Wilprise due to new wells (production) from the Thunderhorse platform.

• Segment  gross margin  amounted  to $242.1 million,  or an increase  of $18.5 million  as compared  to $223.6 million  of the same  period  in 2016. This
increase of $18.5 million was primarily due to our Offshore Pipelines and Services segment earnings from unconsolidated affiliates of $19.8 million, $1.6
million from firm transportation contracts of 150 MMcf/d on MLGT, $1.0 million from new Midla Natchez contracts with higher rates, $1.0 million from
the  acquisition  of  Trans-Union  in  November  2017,  partially  offset  by  a  decrease  in  our  Terminalling  Services  segment  of  $4.9  million  primarily
attributable to a decrease in Cushing storage, higher operating costs at our Harvey terminal, and higher butane costs.

• Adjusted EBITDA decreased to $176.4 million, or an immaterial decrease of 0.7%, as compared to $177.6 million in 2016.

• We distributed $89.4 million to our common unitholders, or $1.65 per common unit, with respect to the year 2017. Our fourth quarter 2017 distribution
was the 26th consecutive distribution since our initial public offering.

61

Operational highlights during the year ended December 31, 2017, include the following:

•  Contracted  capacity  for  our  Terminalling  Services  segment  averaged  4,957,328  Bbls,  representing  a  1.1%  decrease  compared  to  the  same  period  in
2016;

• Average condensate production totaled 64 Mgal/d, representing a 18.9 Mgal/d or 22.8% decrease compared to the same period in 2016;

• Average gross NGL production totaled 326 Mgal/d, representing a 133 Mgal/d or 68.7 % increase compared to the same period in 2016;

•  Throughput  volumes  attributable  to  the  Natural  Gas  Transportation  Services  and  Offshore  Pipelines  and  Services  segments  totaled  730  MMcf/d,
representing a 126 MMcf/d or 14.7% decrease compared to the same period in 2016;

•  Throughput  volumes  attributable  to  the  Liquid  Pipelines  and  Services  segment  totaled  34,248  Bbls/d,  representing  a  1,991  Bbls/d  or  6.2%  increase
compared to the same period in 2016; and

• The percentage of gross margin generated from fee based, fixed margin, firm and interruptible transportation contracts and firm storage contracts was
89.1%, representing a decrease of 2.5%, as compared to the same period in 2016.

Our Operations

We manage our business and analyze and report our results of operations through five reportable segments.

• Gas Gathering and Processing Services. Our Gas Gathering and Processing Services segment provides “wellhead-to-market” services to producers of
natural  gas and NGLs, which include transporting raw natural  gas from various receipt  points through gathering  systems, treating the raw natural  gas,
processing raw natural gas to separate the NGLs from the natural gas, fractionating NGLs, and selling or delivering pipeline quality natural gas and NGLs
to various markets and pipeline systems.

• Liquid Pipelines and Services. Our Liquid Pipelines and Services segment provides transportation, purchase and sales of crude oil from various receipt
points including lease automatic customer transfer (“LACT”) facilities and deliveries to various markets.

• Natural Gas Transportation Services. Our Natural Gas Transportation Services segment transports and delivers natural gas from producing wells, receipt
points  or  pipeline  interconnects  for  shippers  and  other  customers,  which  include  local  distribution  companies  (“LDCs”),  utilities  and  industrial,
commercial and power generation customers.

• Offshore Pipelines and Services. Our Offshore Pipelines and Services segment gathers and transports natural gas and crude oil from various receipt
points to other pipeline interconnects, onshore facilities and other delivery points.

•  Terminalling  Services.  Our  Terminalling  Services  segment  provides  above-ground  leasable  storage  operations  at  our  marine  terminals  that  support
various commercial customers, including commodity brokers, refiners and chemical manufacturers to store a range of products and also includes crude oil
storage in Cushing, Oklahoma and refined products terminals in Texas and Arkansas.

Gas Gathering and Processing Services Segment

Results of operations  from the  Gas Gathering and Processing Services segment  are determined  primarily  by the volumes of natural  gas we gather,  process and
fractionate,  the  commercial  terms  in  our  current  contract  portfolio  and  natural  gas,  crude  oil,  NGL  and  condensate  prices.  We  gather  and  process  natural  gas
primarily pursuant to the following arrangements:

• Fee-Based Arrangements. Under these arrangements, we generally are paid a fixed fee for gathering, processing and transporting natural gas.

• Fixed-Margin Arrangements. Under these arrangements, we purchase natural gas and off-spec condensate from producers or suppliers at receipt points
on  our  systems  at  an  index  price  less  a  fixed  transportation  fee  and  simultaneously  sell  an  identical  volume  of  natural  gas  or  off-spec  condensate  at
delivery  points  on  our  systems  at  the  same,  undiscounted  index  price.  By  entering  into  back-to-back  purchases  and  sales  of  natural  gas  or  offspec
condensate, we are able to lock in a

62

    
    
fixed margin on these transactions. We view the segment gross margin earned under our fixed-margin arrangements to be economically equivalent to the
fee earned in our fee-based arrangements.

• Percent-of-Proceeds  Arrangements (“POP”). Under these arrangements,  we generally gather raw natural gas from producers at the wellhead or other
supply points, transport  it through  our gathering  system,  process it and sell the residue natural  gas, NGLs and condensate  at market  prices.  Where we
provide  processing  services  at  the  processing  plants  that  we  own,  or  obtain  processing  services  for  our  own  account  in  connection  with  our  elective
processing arrangements, we generally retain and sell a percentage of the residue natural gas and resulting NGLs. However, we also have contracts under
which we retain a percentage of the resulting NGLs and do not retain a percentage of residue natural gas. Our POP arrangements also often contain a fee-
based component.

Gross margin  earned  under  fee-based  and fixed-margin  arrangements  is directly  related  to the volume  of natural  gas  that  flows through  our systems  and  is not
directly dependent on commodity prices. However, a sustained decline in commodity prices could result in a decline in throughput volumes from producers and,
thus,  a  decrease  in  our  fee-based  and  fixed-margin  gross  margin.  These  arrangements  provide  stable  cash  flows,  but  upside  in  higher  commodity-price
environments is limited to an increase in throughput volumes from producers. Under our typical POP arrangement, our gross margin is directly impacted by the
commodity prices we realize on our share of natural gas and NGLs received as compensation for processing raw natural gas. However, our POP arrangements
often contain a fee-based component, which helps to mitigate the degree of commodity-price volatility we could experience under these arrangements. We further
seek to mitigate our exposure to commodity price risk through our hedging program. See the information set forth in Part II, Item 7A of this Annual Report under
the caption — Quantitative and Qualitative Disclosures about Market Risk — Commodity Price Risk .

Liquid Pipelines and Services Segment

Results  of  operations  from  the  Liquid  Pipelines  and  Services  segment  are  determined  by  the  volumes  of  crude  oil  transported  on  the  interstate  and  intrastate
pipelines we own. Tariffs associated with our Bakken system are regulated by FERC for volumes gathered via pipeline and trucked to the AMID Truck facility in
Watford City, North Dakota. Volumes transported on our Silver
Dollar system are underpinned by long-term, fee-based contracts. Our transportation arrangements are further described below:

• Firm Transportation Arrangements. Our obligation to provide firm transportation  service means that, pursuant to the agreement with the shipper, we
transport crude oil nominated by the shipper up to the maximum daily quantity specified in the contract. In exchange for that obligation on our part, the
shipper pays a specified reservation charge, whether or not the shipper utilizes the capacity. In most cases, the shipper also pays a variable-use charge
with respect to quantities actually transported by us.

• Uncommitted  Shipper  Arrangements  . Our  obligation  to  provide  interruptible  transportation  service  means  that,  pursuant  to  the  agreement  with  the
shipper,  we  only  transport  crude  oil  nominated  by  the  shipper  to  the  extent  that  we  have  available  capacity.  For  this  service  the  shipper  pays  no
reservation charge but pays a variable-use charge for quantities actually shipped.

• Fee-Based Arrangements . Under these arrangements our operations are underpinned by long-term, fee-based contracts with leading producers in the
Midland Basin. Some of these contracts also have minimum volume commitments as well as some have acreage dedications.

• Buy-Sell Arrangements. We enter into outright purchase and sales contracts as well as buy/sell contracts with counterparties, under which contracts we
gather and transport different types of crude oil and eventually sell the crude oil to either the same counterparty or different counterparties. We account
for such revenue arrangements on a gross basis. Occasionally, we enter into crude oil inventory exchange arrangements with the same counterparty which
the purchase and sale of inventory are considered in contemplation of each other. Revenues from such inventory exchange arrangements are recorded on a
net basis.

Natural Gas Transportation Services Segment

Results of operations from the Natural Gas Transportation Services segment are determined by capacity reservation fees from firm and interruptible transportation
contracts  and  the  volumes  of  natural  gas  transported  on  the  interstate  and  intrastate  pipelines  we  own  pursuant  to  interruptible  transportation  or  fixed-margin
contracts. Our transportation arrangements are further described below:

63

    
    
        
    
• Firm Transportation  Arrangements.  Our obligation  to provide firm transportation  service  means that, pursuant to the agreement  with the shipper, we
transport natural gas nominated by the shipper up to the maximum daily quantity specified in the contract. In exchange for that obligation on our part, the
shipper  pays  a  specified  reservation  charge,  whether  or  not  the  shipper  utilizes  the  capacity.  In  most  cases,  the  shipper  also  pays  a  variable-use  or
commodity charge with respect to quantities actually transported by us.

• Interruptible Transportation Arrangements. Our obligation to provide interruptible transportation service means that, pursuant to the agreement with the
shipper,  we  only  transport  natural  gas  nominated  by  the  shipper  to  the  extent  that  we  have  available  capacity.  For  this  service  the  shipper  pays  no
reservation charge but pays a variable-use or commodity charge for quantities actually shipped.

•  Fixed-Margin  Arrangements.  Under  these  arrangements,  we  purchase  natural  gas  from  producers  or  suppliers  at  receipt  points  on  our  systems  at  an
index  price  less  a  fixed  transportation  fee  and  simultaneously  sell  an  identical  volume  of  natural  gas  at  delivery  points  on  our  systems  at  the  same
undiscounted index price. We view fixed-margin arrangements to be economically equivalent to our interruptible transportation arrangements.

Offshore Pipelines and Services

Results  of  operations  from  the  Offshore  Pipelines  and  Services  segment  are  determined  by  capacity  reservation  fees  from  firm  and  interruptible  transportation
contracts  and  the  volumes  of  natural  gas  transported  on  the  interstate  and  intrastate  pipelines  we  own  pursuant  to  interruptible  transportation  or  fixed-margin
contracts. Our transportation arrangements are further described below:

• Firm Transportation Arrangements . Our obligation to provide firm transportation service means that, pursuant to the agreement with the shipper, we

• Fixed-Margin Arrangements . Under these arrangements,  we purchase natural gas from producers or suppliers at receipt points on our systems at an
index  price  less  a  fixed  transportation  fee  and  simultaneously  sell  an  identical  volume  of  natural  gas  at  delivery  points  on  our  systems  at  the  same
undiscounted index price. We view fixed-margin arrangements to be economically equivalent to our interruptible transportation arrangements.

Terminalling Services Segment

Our Terminalling Services segment provides above-ground leasable storage services at our marine terminals that support various commercial customers, including
commodity  brokers,  refiners  and  chemical  manufacturers  to  store  a  range  of  products,  including  petroleum  products,  distillates,  chemicals  and  agricultural
products. We generally receive fee-based compensation on guaranteed firm storage contracts, throughput fees charged to our customers when their products are
either received or disbursed and other fee-based charges associated with ancillary services provided to our customers, such as excess throughput, truck weighing,
etc. Our firm storage contracts are typically multi-year contracts with renewal options. Our refined products terminals have butane blending capabilities.

Our  Terminalling  Services  segment  consists  of  approximately  2.4  million  barrels  of  storage  capacity  across  three  marine  terminal  sites  located  in  Westwego,
Louisiana; Brunswick, Georgia; and Harvey, Louisiana. Our Terminalling Services segment provides above-ground storage services at our marine terminals that
support  various  commercial  customers,  including  commodity  brokers,  refiners,  and  chemical  manufacturers,  to  store  a  range  of  products,  including  petroleum
products, distillates, chemicals and agricultural products.

Cash distributions received from our unconsolidated affiliates amounted to $90.8 million, $83.0 million, and $20.6 million for the years ended December 31, 2017,
2016,  and  2015,  respectively.  Cash  distributions  derived  from  our  unconsolidated  affiliates  are  primarily  generated  from  fee-based  gathering  and  processing
arrangements.

How We Evaluate Our Operations

Our  management  uses  a  variety  of  financial  and  operational  metrics  to  analyze  our  performance.  We  view  these  metrics  as  important  factors  in  evaluating  our
profitability  and  review  these  measurements  on  at  least  a  monthly  basis  for  consistency  and  trend  analysis.  These  metrics  include  throughput  volumes,  storage
utilization,  segment  gross  margin,  total  segment  gross  margin,  operating  margin,  direct  operating  expenses  on  a  segment  basis,  and  Adjusted  EBITDA  on  a
company-wide basis.

Throughput Volumes

In  our Gas  Gathering  and  Processing  Services  segment,  we  must continually  obtain  new supplies  of  natural  gas,  NGLs and  condensate  to  maintain  or  increase
throughput volumes on our systems. Our ability to maintain or increase existing volumes of natural gas, NGLs and condensate is impacted by i) the level of work-
overs or recompletions of existing connected wells and successful drilling activity of our significant producers in areas currently dedicated to or near our gathering
systems,  ii)  our  ability  to  compete  for  volumes  from  successful  new  wells  in  the  areas  in  which  we  operate,  iii)  our  ability  to  obtain  natural  gas,  NGLs  and
condensate that has been released from other commitments and iv) the volume of natural gas, NGLs and condensate that we purchase from connected systems. We
actively  monitor producer  activity  in the areas  served  by our gathering  and processing  systems  to maintain  current  throughput  volumes  and pursue new supply
opportunities.

In our Liquid Pipelines and Services segment, t he amount of revenue we generate from our crude oil pipelines business depends primarily on throughput volumes.
We  generate  a  portion  of  our  crude  oil  pipeline  revenues  through  long-term  contracts  containing  acreage  dedications  or  minimum  volume  commitments.
Throughput volumes on our pipeline system are affected primarily by the supply of crude oil in the market served by our assets. The revenue generated from our
crude oil supply and logistics business depends on the volume of crude oil we purchase from producers, aggregators and traders and then sell to producers, traders
and  refiners  as  well  as  the  volumes  of  crude  oil  that  we  gather  and  transport.  The  volume  of  our  crude  oil  supply  and  logistics  activities  and  the  volumes
transported by our crude oil gathering and transportation trucks are affected by the supply of crude oil in the markets served directly or indirectly by our assets.
Accordingly, we actively monitor producer activity in the areas served by our crude oil supply and logistics business and other producing areas in the United States
to compete for volumes from crude oil producers. Revenues in this business are also impacted by changes in the market price of commodities that we pass through
to our customers.

In our Natural Gas Transportation Services and Offshore Pipelines and Services segments, the majority of our segment gross margin is generated by firm capacity
reservation charges and interruptible  transportation  services from throughput volumes on our interstate  and intrastate pipelines. Substantially all of the segment
gross  margin  is  generated  under  contracts  with  shippers,  including  producers,  industrial  companies,  LDCs  and  marketers,  for  firm  and  interruptible  natural  gas
transportation on our pipelines. We routinely monitor natural gas market activities in the areas served by our transmission systems to maintain current throughput
volumes and pursue new shipper opportunities.

In  our  Terminalling  Services  segment,  we  generally  receive  fee-based  compensation  on  guaranteed  firm  storage  contracts,  throughput  fees  charged  to  our
customers when their products are either received or disbursed, and other operational charges associated with ancillary services provided to our customers, such as
excess throughput, steam heating and truck weighing at our marine terminals. The amount of revenue we generate from our refined products terminals depends
primarily on the volume of refined products that we handle. These volumes are affected primarily by the supply of and demand for refined products in the markets
served directly or indirectly by our refined products terminals. Our refined products have butane blending capabilities. The volume of crude oil stored at our crude
oil storage facility in Cushing, Oklahoma has no impact on the revenue generated by our crude oil storage business because we receive a fixed monthly fee per
barrel of shell capacity that is not contingent on the usage of our storage tanks.

Storage Utilization

Storage utilization is a metric that we use to evaluate the performance of our Terminalling Services segment. We define storage utilization as the percentage of the
contracted capacity in barrels compared to the design capacity of the tank.

Segment Gross Margin and Total Segment Gross Margin

Segment gross margin and total segment gross margin are metrics that we use to evaluate our performance.

65

We  define  segment  gross  margin  in  our  Gas  Gathering  and  Processing  Services  segment  as  total  revenue  plus  unconsolidated  affiliate  earnings  less  unrealized
gains (losses) on commodity derivatives, construction and operating management agreement income and less the cost of sales.

We define segment gross margin in our Liquid Pipelines and Services segment as total revenue plus unconsolidated affiliate earnings less unrealized gains (losses)
on commodity derivatives and less the cost of sales in connection with fixed-margin arrangements. Substantially all of our gross margin in this segment is fee-
based or fixed-margin, with little to no direct commodity price risk.

We define segment gross margin in our Natural Gas Transportation Services segment as total revenue plus unconsolidated affiliate earnings less the cost of sales in
connection with fixed-margin arrangements. Substantially all of our gross margin in this segment is fee-based or fixed-margin, with little to no direct commodity
price risk.

We define segment gross margin in our Offshore Pipelines and Services segment as total revenue plus unconsolidated affiliate earnings less the cost of sales in
connection with fixed-margin arrangements. Substantially all of our gross margin in this segment is fee-based or fixed-margin, with little to no direct commodity
price risk.

We define segment gross margin in our Terminalling Services segment as total revenue less cost of sales and direct operating expense which includes direct labor,
general materials and supplies and direct overhead.

Total segment gross margin is a supplemental non-GAAP financial measure that we use to evaluate our performance. We define total segment gross margin as the
sum of the segment gross margins for our Gas Gathering and Processing Services, Liquid Pipelines and Services, Natural Gas Transportation Services, Offshore
Pipelines and Services, and Terminalling Services segments. The GAAP measure most directly comparable to total segment gross margin is Net loss attributable to
the Partnership. For a reconciliation of total segment gross margin to net loss, see Non-GAAP Financial Measures below.

Operating Margin

We define operating margin as total segment gross margin less other direct operating expenses. The GAAP measure most directly comparable to operating margin
is net loss attributable to the Partnership. For a reconciliation of operating margin to net loss, see Non-GAAP Financial Measures below.

Direct Operating Expenses

Our  management  seeks  to  maximize  the  profitability  of  our  operations  in  part  by  minimizing  direct  operating  expenses  without  sacrificing  safety  or  the
environment.  Direct  labor  costs,  insurance  costs,  ad  valorem  and  property  taxes,  repair  and  non-capitalized  maintenance  costs,  integrity  management  costs,
utilities, lost and unaccounted for gas, and contract services comprise the most significant portion of our operating expenses. These expenses are relatively stable
and largely independent of throughput volumes through our systems but may fluctuate depending on the activities performed during a specific period.

Adjusted EBITDA

Adjusted  EBITDA  is  a  supplemental  non-GAAP  financial  measure  used  by  our  management  and  external  users  of  our  financial  statements,  such  as  investors,
commercial  banks,  research  analysts  and  others,  to  assess:  the  financial  performance  of  our  assets  without  regard  to  financing  methods,  capital  structure  or
historical cost basis; the ability of our assets to generate cash flow to make cash distributions to our unitholders and our General Partner; our operating performance
and  return  on  capital  as  compared  to  those  of  other  companies  in  the  midstream  energy  sector,  without  regard  to  financing  or  capital  structure;  and  the
attractiveness
of capital projects and acquisitions and the overall rates of return on alternative investment opportunities.

We define Adjusted EBITDA as net loss attributable to the Partnership, plus depreciation, amortization and accretion expense, interest expense, debt issuance cost,
unrealized  losses  on  derivatives,  non-cash  charges  such  as  non-cash  equity  compensation  expense,  and  charges  that  are  unusual  such  as  transaction  expenses
primarily associated with our acquisitions (such as JPE, VKGS, Delta House, Panther and Trans-Union), income tax expense, distributions from unconsolidated
affiliates  and  our  General  Partner's  contribution,  less  earnings  in  unconsolidated  affiliates,  gains  (losses)  that  are  unusual  such  as  gain  on  revaluation  of  equity
interest, and the gain on sale of the Propane Business, other, net and gain on sale of assets, net.

The GAAP measure most directly comparable to our performance measure Adjusted EBITDA is net loss attributable to the Partnership. For a reconciliation of net
loss to Adjusted EBITDA , see Non-GAAP Financial Measures below.

Note about Non-GAAP Financial Measures

66

Total  segment  gross  margin,  operating  margin  and  Adjusted  EBITDA  are  performance  measures  that  are  non-GAAP  financial  measures.  Each  has  important
limitations  as an analytical  tool because  they exclude some, but not all, items that affect the most directly comparable GAAP financial  measures. Management
compensates  for  the  limitations  of  these  non-GAAP  measures  as  analytical  tools  by  reviewing  the  comparable  GAAP  measures,  understanding  the  differences
between the measures and incorporating these data points into management’s decision-making process.

You should not consider total segment gross margin, operating margin, or Adjusted EBITDA in isolation or as a substitute for, or more meaningful than analysis
of, our results as reported under GAAP. Total segment gross margin, operating margin and Adjusted EBITDA may be defined differently by other companies in
our industry. Our definitions of these non-GAAP financial measures may not be comparable to similarly titled measures of other companies, thereby diminishing
their utility.

The following tables reconcile the non-GAAP financial measures of total segment gross margin, operating margin and Adjusted EBITDA used by management to
Net loss attributable to the Partnership, their most directly comparable GAAP measure, for the years ended December 31, 2017, 2016, and 2015 (in thousands):

(1) Amounts  primarily  represent  adjustments  related  to  depreciation,  amortization  and  accretion,  unrealized  (gain)  loss  on derivatives,  (gain)  loss  on asset  sales,
goodwill impairment, our transaction expenses and gain on the sale of our Propane Business.

(2) Interest expenses and Adjusted EBITDA associated with the year ended December 31, 2016 have been revised from the recasted information filed by us on a
Current Report on Form 8-K on December 7, 2017, as amended by a Current Report on Form 8-K/A filed on December 12, 2017. Interest expense, as presented
above, includes interest expense as reported in our consolidated statement of operation minus amortization of deferred financing cost minus unrealized gain or loss
in interest rate swaps.

General Trends and Outlook

During 2018, our business objectives will continue to focus on maintaining stable cash flows from our existing assets and executing on growth opportunities to
increase  our  long-term  cash  flows.  We  believe  the  key  elements  to  stable  cash  flows  are  the  diversity  of  our  asset  portfolio  and  our  fee-based  business  which
represents a significant portion of our expected gross margins.

We anticipate maintenance capital expenditures between $14.0 million and $19.0 million, and approved expenditures for expansion capital between $65.0 million
and $85.0 million, for the year ending December 31, 2018. Forecast growth capital expenditures include East Texas Processing consolidation, expansion of the
Harvey terminal, continued build-out of the Bakken system, continued development of the Silver Dollar System and other organic growth projects.

We expect to continue to pursue a multi-faceted growth strategy, which includes maximizing drop down opportunities provided by our relationship with ArcLight,
capitalizing on organic expansion and pursuing strategic third-party acquisitions in order to grow our cash flows. We expect commodity prices in 2018 to increase
compared  to  2017  and  as  a  result  we  expect  producer  and  supplier  activities  to  be  impacted,  which  may  increase  the  growth  rate  of  our  Gas  Gathering  and
Processing Services and Natural

Gas Transportation Services segments. We also expect the SXE Transactions to be accretive to our Adjusted EBITDA upon consummation.

We  expect our business to continue  to be affected  by the  key trends  and outlook discussed  below. Our expectations  are based on assumptions  made  by us and
information currently available to us. To the extent our underlying assumptions prove to be incorrect, our actual results may vary materially from our expected
results.

In the fourth quarter of 2017, we were notified by the operator of FPS that certain third party-owned upstream infrastructure would require remedial work, resulting
in a temporary curtailment of production flow at Delta House. This remediation is scheduled to be completed later in the second quarter of 2018, at which time full
production is anticipated to resume flowing into Delta House.

Gas Gathering and Processing Services Segment. Except for our fee-based contracts, which may be impacted by throughput volumes, the profitability of our Gas
Gathering and Processing Services segment is dependent upon commodity prices, natural gas supply, and demand for natural gas, NGLs and condensate.

Liquid  Pipelines  and  Services  Segment.  The  profitability  of  our  Liquid  Pipelines  and  Services  segment  is  dependent  upon  the  price  of  crude  oil.  Throughput
volumes could decline should crude oil prices remain low resulting in decreased production in our areas of operation.

Natural  Gas  Transportation  Services  and  Offshore  Pipelines  and  Services  Segments.  Profitability  of  our  Natural  Gas  Transportation  Services  and  Offshore
Pipelines  and  Services  segments  are  dependent  upon  the  demand  to  transport  natural  gas  pursuant  under  our  firm  and  interruptible  transportation  contracts.
Throughput volumes could decline should natural gas prices and drilling levels decline.

Terminalling Services Segment. The profitability of our Terminalling Services segment is dependent upon the demand from our customers to store their products,
which  is  generally  not  tied  to  the  crude  oil  and  natural  gas  commodity  markets.  Currently,  we  have  not  experienced  deterioration  of  terminal  gross  margin  in
connection with the volatility of the natural gas, crude oil, NGL or condensate markets. Further, the terms of our firm storage contracts are multiple years, with
renewal options.

Average daily prices for NYMEX West Texas Intermediate crude oil ranged from a high of $ 66.27 per barrel to a low of $42.48 per barrel from January 1, 2017
through March 26, 2018 . Average daily prices for NYMEX Henry Hub natural gas ranged from a high of $6.24 per MMBtu to a low of $2.44 per MMBtu from
January 1, 2017 through March 26, 2018 . We are unable to predict future potential movements in the market price for natural gas, crude oil and NGLs and thus,
cannot predict the ultimate impact of prices on our operations. If commodity prices decline, this could lead to reduced profitability and may impact our liquidity,
compliance  with  financial  covenants  in  our  revolving  credit  facility,  and  our  ability  to  maintain  our  current  distribution  levels.  Our  long-term  view  is  that  as
economic conditions improve and regulation burden is reduced, as it has been the case under the current administration, commodity prices should reach levels that
will support continued natural gas and crude oil production in the United States. Reduced profitability, if any, may result in future potential non-cash impairments
of long-lived assets, goodwill, or intangible assets.

On January 26, 2018 the Board of Directors of our General Partner declared a quarterly cash distribution of $0.4125 per common unit or $1.65 per common unit on
an annualized basis. The distribution was paid on February 14, 2018, to unitholders of record as of the close of business on February 7, 2018. The amount of our
cash  distributions  on  our  units  principally  depends  upon  the  amount  of  cash  we  generate  from  our  operations,  which  could  be  adversely  impacted  by  market
conditions and factors outside of our control. The Partnership Agreement allows us to reduce or eliminate quarterly distributions, if required to maintain ongoing
operations.

Capital Markets. Volatility in the capital markets may impact our operations in multiple ways, including limiting our producers' ability to finance their drilling and
workover programs and limiting our ability to fund drop downs, organic growth projects and acquisitions.

Results of Operations

70

Net loss attributable to the Partnership increased to $223.0 million, or 334.6%, as compared to a net loss of $51.3 million in 2016, which was primarily due to a
combination of an increase in the operating loss of $233.9 million, including non-cash impairment charges totaling $194.6 million related to non-core assets and
goodwill,  and  increased  interest  expense  of  $45.0  million  associated  with  higher  average  debt  balances  from  our  growth  initiatives  as  well  as  higher  average
interest costs, offset primarily by the net gain on disposition of the Propane Business of $47.4 million and the gain of $36.0 million recognized in our consolidated
statement of operations for the year ended December 31, 2017 related to the MPOG acquisition. This acquisition of the 33.3% remaining ownership of MPOG
resulted in a change of control from investment in unconsolidated affiliates to a wholly-owned consolidated subsidiary, resulting in the recognized gain.

Total segment gross margin increased by $18.5 million, or 8.2% , for the year ended to December 31, 2017 to $242.1 million as compared to 2016 . This increase
of $18.5 million was primarily due to our Offshore Pipelines and Services segment earnings from unconsolidated affiliates of $19.8 million, $1.6 million from new
firm transportation contracts of 150 MMcf/d on MLGT, $1.0 million from new Midla Natchez contracts with higher rates, and $1.0 million from the acquisition of
Trans-Union in November 2017, partially offset by a decrease in our Terminalling Services segment of $4.9 million primarily attributable to a decrease in Cushing
storage, higher operating costs at our Harvey terminal, and higher butane costs.

Adjusted EBITDA decreased to $176.4 million, or an immaterial decrease of 0.7% , as compared to $177.6 million in 2016 .

We distributed $89.4 million and $112.1 million to holders of our common units during the years ended December 31, 2017 and 2016 , respectively.

Year ended December 31, 2017 , compared to year ended December 31, 2016

Commodity Sales . Commodity sales revenue for the year ended December 31, 2017 was $496.9 million compared to $439.4 million for the year ended December
31, 2016 . This increase of $57.5 million was primarily due to the following:

•

•
•
•

•

•

an increase in our Gas Gathering and Processing Services segment from sales of NGLs and condensate at the Longview plant of $44.4 million due to new
contracts;
an increase in our Liquid Pipelines and Services segment due to a net increase in marketing contracts totaling $15.4 million;
an increase in our Natural Gas Transportation Services segment of $3.3 million due to higher average index prices on our Magnolia system;
an increase in our Offshore Pipelines and Services segment of $4.7 million due to higher volumes as a result of a new well drilled in December 2016 at
Mud Lake, Louisiana on our Gloria system;
an increase in our Terminalling Services segment of $1.2 million driven by an increase in butane blending sales pricing at our Caddo Mills facility; which
were
partially offset by the reduced NGL and condensate volumes in our Gas Gathering and Processing Services segment at our Chatom/Bazor Ridge plants for
$11.5 million due to lower system volumes from production declines, the loss of Y-grade product and plant downtime in the fourth quarter of 2017.

Services Revenue . Our service revenue for the year ended December 31, 2017 was $154.7 million compared to $151.2 million for the year ended December 31,
2016 . This increase of $3.5 million was primarily due to the following:

•
•
•
•
•
•

•

an increase of $7.0 million from higher management fees on AmPan;
an increase of $5.3 million due to the VKGS acquisition in June 2017;
an increase of $1.6 million due to Firm Transportation agreements (150 MMcf/d) on MLGT;
an increase of $1.0 million due to higher rates on our new Midla Natchez line;
an increase of $1.0 million due to the Trans-Union acquisition in November 2017; which were
partially  offset  by  various  items  on  our  High  Point  Gathering  Transmission  ("HPGT")  line  for  $10.0  million  from  the  shut-in  of  our  dry  line,  firm
transportation contract expirations, Hurricane Nate impacts and compressor maintenance; and
increased trucking activities on AMID Liquid Trucking with our own affiliates resulting in reduced third-party trucking revenues of $3.4 million.

Cost of sales . Cost of sales for the year ended December 31, 2017 , was $457.4 million compared to $393.4 million in the year ended December 31, 2016 . This
increase of $64.0 million was primarily due to net new marketing transactions in 2017 compared to 2016 of $16.7 million in our Liquid Pipelines and Services
segment, $34.4 million mostly due to increase of NGL, natural gas and condensate transactions at the Longview plant, $3.6 million due to the addition of a new
well at Mud Lake, Louisiana on our Gloria system, and $2.7 million due to higher average index prices on our Magnolia system.

Total Segment Gross Margin . Total segment gross margin for the year ended December 31, 2017 , was $242.1 million compared to $223.6 million for the year
ended  December  31,  2016  .  This  increase  of  $18.6  million  was  primarily  due  to  our  Offshore  Pipelines  and  Services  segment  earnings  from  unconsolidated
affiliates of $19.8 million, $1.6 million from new firm transportation contracts of 150 MMcf/d on MLGT, $1.0 million from new Midla Natchez contracts with
higher rates, $1.0 million from the acquisition of Trans-Union in November 2017, partially offset by our Terminalling Services segment of $5.1 million primarily
attributable to a decrease in Cushing storage, higher operating costs at our Harvey terminal, and higher butane costs.

Direct Operating Expenses . Direct operating expenses for the year ended December 31, 2017 were $82.3 million compared to $71.5 million for the year ended
December 31, 2016 . This increase of $10.8 million was primarily due to a $2.3 million increase associated with the acquisition of VKGS, $1.7 million due to the
Panther acquisition, and $1.8 million  incremental  operating expenses pertaining  to our Harvey facility  expansion as a result of higher repairs and maintenance,
contractor  services  and  security  costs,  $1.7  million  due  to  employee  headcount  increases,  $1.3  million  in  environmental  regulatory  compliance  costs,  and  $0.9
million in additional repairs and maintenance.

Corporate Expenses . Corporate expenses for the year ended December 31, 2017 , were $112.1 million compared to $89.4 million for the year ended December
31, 2016 . This increase of $22.6 million was primarily due to transaction related costs associated with the JPE merger and the SXE Transactions of $14.8 million,
$4.0 million in audit and tax fees, $2.7 million in legal and regulatory compliance fees in support of corporate activities, and $1.1 million due to information and
technology costs related to systems and licenses that were either implemented or initiated during 2017.

Depreciation, Amortization and Accretion . Depreciation, amortization and accretion for the year ended December 31, 2017 , was $103.4 million compared to
$90.9 million for the year ended December 31, 2016 . This increase of $12.6 million was primarily due to the acceleration of the accumulated amortization of a
JPE customer relationship carried out in the beginning of the first quarter of 2017 through August 2017 for $10.0 million. The remaining difference is primarily
due to increases in depreciation,

73

amortization and accretion related to our Panther acquisition in the third quarter of 2017 and the Trans-Union acquisition in the fourth quarter of 2017.

Impairment of Long-lived assets / intangible assets. During the fourth quarter of 2017, we identified certain assets where events or circumstances indicated we
may not recover their carrying value. Due to plant shut downs in the quarter and changes in our forecast volumes on certain assets, as part of our annual budget
process we have made operational decisions that impact our ability to recover the carrying value of assets. As a result, asset impairment charges of $ 116.6 million
were recorded in the fourth quarter of 2017, of which $103.9 million was related to our property, plant and equipment and $12.7 million was related to intangible
assets. Of the $103.9 million impairment charge to our property, plant and equipment, $97.8 million related to our Gas Gathering and Processing Services segment,
$3.9 million related to our Natural Gas Transportation Services segment and $2.2 million related to our Liquid Pipelines and Services segment. Additionally, of the
$12.7 million impairment charge to our intangible assets, $10.8 million related to our Gas Gathering and Services segment and $1.9 million related to our Liquid
Pipelines and Services segment.

Impairment of Goodwill. Goodwill impairment expense for the year ended December 31, 2017 was $78.0 million compared to $2.7 million for the year ended
December  31,  2016.  In  2017,  we  recognized  goodwill  impairment  charges  totaling  $78.0  million  to  our  Liquid  Pipelines  and  Services  segment.  In  2016,  we
recognized goodwill impairment charges totaling $2.7 million related to our JP Liquids business.

Interest Expense . Interest expense for the year ended December 31, 2017 , was $66.5 million compared to $21.4 million for the year ended December 31, 2016 .
This increase of $45.1 million was primarily due to higher outstanding borrowings under our revolving credit facilities, and an increase in our weighted-average
interest rate.

Earnings in Unconsolidated Affiliates. Earnings in unconsolidated affiliates for the year ended December 31, 2017 were $63.1 million compared to $40.2 million
for the year ended December 31, 2016 . This increase of $22.9 million was primarily due to the incremental ownership in Delta House in the fourth quarter of 2016
and our subsequent increases in ownership in November 2017 for $11.2 million, $5.4 million on Destin as a result of twelve months of ownership reflected in 2017
compared to eight months of ownership in 2016, as well as higher volumes on our Okeanos system for $4.0 million. Additionally, there was a $3.0 million increase
driven by increasing volumes on Tri-States and Wilprise due to new wells (production) from the Thunderhorse platform.

Income  (Loss)  from  Discontinued  Operations.  Income  (loss)  from  discontinued  operations  represents  the  Partnership's  income  (loss)  from  the  discontinued
operations, including gain or loss on sales. Income from discontinued operations, net of tax for the year ended December 31, 2017 of $44.1 million was associated
with the sale of the Propane Business on September 1, 2017, whereas loss from discontinued operations, net of tax for the year ended December 31, 2016, of $4.7
million was associated primarily with the sale of the Mid-Continent Business on February 1, 2016. See Note 4 - Discontinued Operations .

Year ended December 31, 2016 , compared to year ended December 31, 2015

Commodity Sales . Commodity sales for the year ended December 31, 2016 was $439.4 million compared to $613.2 million for the year ended December 31, 2015
. This decrease of $173.8 million was primarily due to the following:

•

•

•
•

•

a decrease in crude oil sales revenue of $152.9 million due to a decrease in sales volumes of 15,830 (bbls/day) from an overall reduction in our customer
crude oil production volumes in our areas of operation;
a decrease in natural gas revenue of $10.7 million primarily due to lower realized natural gas prices of $2.51 /Mcf, which is a decrease of $0.40 /Mcf or
13.7% period over period;
a decrease in condensate revenues of $6.7 million due to lower realized condensate prices of $0.11 /gal or 11.3% period over period;
a decrease in NGL revenues of $6.3 million due to lower gross NGL production volumes of 38.2 Mgal/d from our Gas Gathering and Processing Services
segment and lower realized NGL prices of $0.57 /gal, which is a decrease of $0.01 /gal period over period; and
these decreases were partially offset by an increase in crude oil gathering fee-based revenues of $4.7 million.

Services Revenue . Our service revenue for the year ended December 31, 2016 was $151.2 million compared to $135.7 million for the year ended December 31,
2015 . This increase of $15.5 million was primarily due to the following:

•

an  increase  in  firm  and  interruptible  transportation  of  $8.5  million  primarily  as  a  result  of  the  Pascagoula  plant  shutdown  and  additional  revenue
associated  with  our  Gulf  of  Mexico  pipeline  (the  "Gulf  of  Mexico  Pipeline")  which  we  acquired  from  Chevron  Pipeline  Company  and  Chevron
Midstream Pipeline, LLC in April 2016. The Pascagoula plant is not controlled or owned by the Partnership, and the shutdown required volumes to be
redirected to our High Point system; and

74

•

an increase in Terminalling Services segment revenue of $9.8 million as a result of incremental storage utilization and ancillary increases.

Cost of Sales . Cost of sales for the year ended December 31, 2016 was $393.4 million compared to $567.7 million in the year ended December 31, 2015 . This
decrease of $174.3 million was due to lower natural gas purchases of $10.4 million. There was also a decrease in crude oil purchases of $162.8 million which was
driven by the 2016 reduction in crude sales volumes and overall reduction in crude prices. The NGL purchases decrease was primarily due to the reduction in NGL
sales volumes. NGL sales volumes decreased 30,000/gallons per day in 2016 compared to 2015 due to a decline in volumes associated with oilfield services as a
result of lower exploration and production activity and overall warmer than normal temperatures.

Total Segment Gross Margin . Total segment gross margin for the year ended December 31, 2016 was $223.6 million compared to $179.9 million for the year
ended December  31,  2015  .  This  increase  of  $43.7  million  was  primarily  due  to  our  increased  Offshore  Pipelines  and  Services  segment  gross  margin  of  $8.5
million as a result of increased revenues received by the Partnership due to the Pascagoula plant shutdown. The Pascagoula plant is not controlled or owned by the
Partnership, and the shutdown required volumes to be directed to our High Point system. Additionally, the incremental earnings from our equity method investees
increased by $32.0 million, of which $29.9 million was attributable to our Offshore Pipelines and Services segment.

Direct Operating Expenses . Direct operating expenses for the year ended December 31, 2016 were $71.5 million compared to $71.7 million in the year ended
December 31, 2015 . This decrease of $0.2 million was primarily due to a decrease of contract services and labor costs.

Corporate Expenses . Corporate expenses for the year ended December 31, 2016 were $89.4 million compared to $65.3 million for the year ended December 31,
2015 . This increase of $24.1 million was primarily due to corporate relocation expenses of $9.1 million, JPE Merger expenses of $7.2 million, and increases in
salaries,  wages  and  benefits  of  $2.6  million  due  to  increased  employee  expenses  as  we  transitioned  our  corporate  headquarters  from  Denver  to  Houston,
information and technology maintenance costs of $1.1 million primarily related to systems and licenses that were implemented in the prior year, contract services
of $1.0 million, and legal and regulatory compliance fees of $0.7 million in support of corporate activities.

Depreciation, Amortization and Accretion . Depreciation, amortization and accretion for the year ended December 31, 2016 was $90.9 million compared to $81.3
million for the year ended December 31, 2015 . This increase of $9.6 million was primarily due to incremental depreciation of fixed assets related to our Gulf of
Mexico Pipeline acquisition in April 2016, our Mesquite joint venture which began operations in April 2016, and our Bakken system which began operations in
October 2015.

Impairment of Goodwill. Goodwill impairment expense for the year ended December 31, 2015 was $148.5 million compared to $2.7 million for the year ended
December 31, 2016. The 2015 impairment charges were comprised of $95.0 million and $23.6 million related to the Costar and Lavaca assets, respectively, which
were acquired in prior years, and $29.9 million in our Liquid Pipelines and Services reportable segment relating to the Crude Oil Supply and Logistics business.
The 2016 impairment charges of $2.7 million were related to our JP Liquids business.

Interest Expense . Interest expense for the year ended December 31, 2016 , was $21.4 million compared to $20.1 million for the year ended December 31, 2015 .
This increase of $1.3 million was primarily due to higher outstanding borrowings under our revolving credit facilities, and an increase in our weighted average
interest rate, offset by $10.4 million of unrealized gains on our interest rate swaps.

Earnings in Unconsolidated Affiliates. Earnings in unconsolidated affiliates for the year ended December 31, 2016 were $40.2 million compared to $8.2 million
for the year ended December 31, 2015. This increase of $32.0 million was primarily due to incremental earnings of $22.8 million related to our investment in Delta
House and $9.7 million related to the interests in the entities underlying the Emerald Transactions which were acquired in April 2016.

Discontinued Operations . Loss from discontinued operations for the year ended December 31, 2016 was $4.7 million compared to $0.4 million for the year ended
December 31, 2015. The increase in loss from discontinued operations of $4.3 million was primarily due to a decrease in gross margin of $1.9 million and $3.1
million  associated  with  our  Propane  Business  and  Mid-Continent  Business,  respectively.  The  decrease  in  our  Propane  Business  was  primarily  attributable  to  a
reduction in NGL and refined product sales driven by a decline in volumes associated with oilfield services and overall warmer than normal temperatures sustained
in the year ended December 31, 2016. The decrease in our Mid-Continent Business was primarily due to a decrease in crude oil sales volumes which was driven by
a decline in oilfield services. Additionally, unrealized gains associated with the Propane commodity swaps decreased $10.7 million to $1.1 million as of December
31,  2016  from  $11.8  million  as  of  December  31,  2015,  and  loss  on  sale  of  assets  related  to  the  Propane  Business  increased  $1.1  million  for  the  year  ended
December 31, 2016.

Year Ended December 31, 2017 , Compared to Year Ended December 31, 2016

Commodity Sales . Commodity sales for the year ended December 31, 2017 were $124.9 million compared to $91.4 million for the year ended December 31, 2016
. This increase of $33.5 million was primarily due to the following:

•

•

increased revenue from sales of NGLs and condensate at the Longview plant of $44.4 million due to three new contracts, two of which started in the first
quarter of 2017 and one ongoing contract; and
offsetting  this  was  reduced  NGL  and  condensate  volumes  at  our  Chatom/Bazor  Ridge  plants  of  $11.5  million  due  to  lower  system  volumes  from
production declines and the loss of Y-grade product and plant downtime in the fourth quarter of 2017.

Services Revenue. Services revenue for the year ended December 31, 2017 was $21.9 million compared to $22.6 million for the year ended December 31, 2016 .
This decrease of $0.7 million was primarily driven by lower drilling activity resulting in a decline in compression and gathering charges of $1.7 million on Lavaca,
offset by an increase from a pipeline recovery fee of $1.3 million at Chatom/Bazor Ridge.

Cost of Sales . Cost of sales for the year ended December 31, 2017 was $98.2 million compared to $63.8 million for the year ended December 31, 2016 . This
increase of $34.4 million was primarily due to increase of NGL, natural gas and condensate sales at the Longview plant, as mentioned above, offset by reduced
NGL and condensate volumes at Chatom/Bazor Ridge.

Segment Gross Margin . Segment gross margin for the year ended December 31, 2017 was $49.0 million compared to $48.2 million for the year ended December
31, 2016 . This increase of $0.8 million was mainly due to reasons discussed above under Commodity Sales.

Direct Operating Expenses . Direct operating expenses for the year ended December 31, 2017 were $32.0 million compared to $33.8 million for the year ended
December 31, 2016 . This decrease of $1.8 million was primarily the result of lower compressor rentals for $0.8 million due to the ongoing cost cutting efforts and
$0.7 million decrease in outside services at our Longview facility.

Year Ended December 31, 2016 , Compared to Year Ended December 31, 2015

Commodity Sales . Commodity sales for the year ended December 31, 2016 was $91.4 million compared to $107.7 million for the year ended December 31, 2015 .
This decrease of $16.3 million was primarily due to the following:

•
•

lower realized natural gas, NGL, and condensate prices of 23.2%, 1.9%, and 10.9%, respectively; and
lower average NGL and condensate production of 38.2 Mgal/d and 14.1 Mgal/d, respectively, primarily due to a decrease in volumes at our Longview
system.

Services Revenue. Services revenue for the year ended December 31, 2016 was $22.6 million compared to $30.2 million for the year ended December 31, 2015 .
This decrease of $7.6 million was primarily due to lower average throughput and plant inlet volumes of 19.4 MMcf/d and 18.8 MMcf/d, respectively.

Cost of Sales . Cost of sales for the year ended December 31, 2016 was $63.8 million compared to $73.0 million for the year ended December 31, 2015 . This
decrease of $9.2 million was primarily due to lower realized commodity prices as well as lower NGL and condensate purchased volumes at our Longview system.

Segment Gross Margin . Segment gross margin for the year ended December 31, 2016 was $48.2 million compared to $65.7 million for the year ended December
31, 2015 . This decrease of $17.5 million was primarily due to lower production on our Longview and Lavaca systems.

Direct Operating Expenses . Direct operating expenses for the year ended December 31, 2016 were $33.8 million compared to $35.3 million for the year ended
December 31, 2015 . This decrease of $1.5 million was primarily due to lower compressor rentals due to ongoing cost cutting efforts.

Year Ended December 31, 2017 Compared to Year Ended December 31, 2016

Commodity Sales . Commodity sales for the year ended December 31, 2017 were $319.9 million compared to $304.5 million for the year ended December 31,
2016 . This increase of $15.4 million was primarily due to a net increase in marketing contracts.

Services Revenue. Services revenue for the year ended December 31, 2017 was $16.4 million compared to $19.0 million for the year ended December 31, 2016 .
This decrease of $2.6 million was primarily due to increased activities in our Liquid Pipelines and Services segment with our affiliates resulting in a reduction in
third party trucking revenue of $3.4 million, offset by a $0.7 million increase due to new exploration and production wells coming on-line in 2017 and associated
capital recovery fees, and $0.5 million from increased trucking barrels.

Cost of Sales . Cost of sales for the year ended December 31, 2017 was $312.8 million compared to $293.6 million for the year ended December 31, 2016 . This
increase of $19.2 million was primarily due to the net increase in marketing contracts of $16.7 million.

Earnings in Unconsolidated Affiliates. Earnings in unconsolidated affiliates for the year ended December 31, 2017 were $5.1 million compared to $2.1 million for
the year ended December 31, 2016. This $3.0 million increase is driven by increasing volumes on Tri-States and Wilprise due to new wells (production) from the
Thunderhorse platform.

Segment Gross Margin . Segment gross margin for the year ended December 31, 2017 was $28.0 million compared to $31.6 million for the year ended December
31, 2016 . This decrease of $3.6 million was due to the reasons discussed above.

Direct Operating Expenses . Direct operating expenses for the year ended December 31, 2017 were $12.3 million compared to $10.1 million for the year ended
December 31, 2016 . This increase of $2.2 million was primarily due to the $1.5 million incremental expenses associated with our Crude Trucking bulk purchases
of vehicle diesel and lubricants and $0.7 million due to Silver Dollar Pipeline employee headcount and contract services increase.

Year Ended December 31, 2016 , Compared to Year Ended December 31, 2015

Commodity Sales . Commodity sales for the year ended December 31, 2016 were $304.5 million compared to $457.4 million for the year ended December 31,
2015 . This decrease of $152.9 million was primarily due to a decrease in crude oil sales volumes to 24,425 barrels per day for the year ended December 31, 2016
from 40,255 barrels per day for the year ended December 31, 2015. These decreases are primarily due to an overall reduction in our customer crude oil production
volumes in our areas of operation.

Services Revenue. Services revenue for the year ended December 31, 2016 was $19.1 million compared to $23.0 million for the year ended December 31, 2015 .
This decrease of $3.9 million was primarily due to reduction in NGL revenue from lower NGL trucking volumes driven by a decline in volumes associated with
oilfield services and overall warmer than normal temperatures sustained in the year ended December 31, 2016. There was also a decrease in crude oil throughput
volumes to 32,257 barrels per day for the year ended December 31, 2016 from 34,946 barrels per day for the year ended December 31, 2015. These decreases are
due to an overall reduction in our customer crude oil production volumes in our areas of operation. However, producer activity around our Silver Dollar Pipeline
increased, in late 2016, resulting in average pipeline throughput volumes of approximately 31,000 barrels per day in the quarter ended December 31, 2016.

Cost of Sales . Cost of sales for the year ended December 31, 2016 was $293.6 million compared to $454.1 million for the year ended December 31, 2015 . This
decrease of $160.5 million was primarily due to a decrease in crude oil sales volumes resulting from an overall reduction in our customer crude oil production
volumes, as described above under Services Revenue.

Earnings in Unconsolidated Affiliates. Earnings in unconsolidated affiliates for the year ended December 31, 2016 increased $2.1 million. This change was driven
by the Emerald transaction that occurred in April 2016 adding interests in the Wilprise and Tri-States entities that own and operate pipeline systems.

Segment Gross Margin . Segment gross margin for the year ended December 31, 2016 was $31.6 million compared to $26.4 million for the year ended December
31, 2015 . This increase of $5.2 million was primarily due to an increase in crude oil sales margin of $10.0 million due to the capturing of more favorable margins
associated  with previously  stored inventory  during contango market  conditions  as well as more favorable  regional pricing spreads on bulk purchased crude oil.
This increase was partially offset by a decrease in crude oil sales and throughput volumes of $6.9 million and $0.7 million, respectively.

Direct Operating Expenses . Direct operating expenses for the year ended December 31, 2016 were $10.1 million compared to $9.9 million for the year ended
December 31, 2015 . This increase of $0.2 million was primarily due to the incremental expenses associated with our Bakken system, partially offset by reductions
in personnel costs from lower headcount.

Services Revenue. Services revenue for the year ended December 31, 2016 was $18.1 million compared to $16.0 million for the year ended December 31, 2015 .
This increase of $2.1 million was primarily due to higher average throughput volumes of 26 MMcf/d from firm transportation contracts associated with our MLGT
pipeline.

Cost of Sales . Cost of sales for the year ended December 31, 2016 was $21.3 million compared to $21.9 million for the year ended December 31, 2015 . This

Year Ended December 31, 2017 Compared to Year Ended December 31, 2016

Commodity Sales . Commodity sales for the year ended December 31, 2017 were $11.5 million compared to $6.8 million for the year ended December 31, 2016 .
This increase of $4.7 million was primarily due to a new well in December 2016 at Mud Lake, Louisiana on our Gloria system.

Services Revenue. Services revenue for the year ended December 31, 2017 was $43.5 million compared to $40.5 million for the year ended December 31, 2016 .
This increase of $3.0 million was primarily due to $7.0 million of higher management fees on AmPan, and $5.3 million due to the acquisition of VKGS in June
2017, offset by a $10.0 million reduction on HPGT resulting from the shut-in of the dry line, firm transportation contract expiration, Hurricane Nate impacts, and
compressor maintenance.

Cost  of  Sales  .  Cost  of  sales  for  the  year  ended  December  31, 2017  was  $9.3  million  compared  to  $3.0  million  for  the  year  ended  December  31,  2016  . This
increase of $6.3 million was primarily due to the addition of a new well in December 2016 at Mud Lake, Louisiana on our Gloria system for $3.6 million, $1.2
million due to imbalances on HPGT, $0.6 million of additional cost on Quivira as a result of a new condensate contract in November 2017, and $0.5 million due to
the acquisition of VKGS in June 2017.

Earnings in Unconsolidated Affiliates. Earnings in unconsolidated affiliates for the year ended December 31, 2017 were $57.9 million compared to $38.1 million
for the year ended December 31, 2016. This increase of $19.8 million was primarily due to the incremental ownership in Delta House in the fourth quarter of 2016
and our subsequent increases in ownership in November 2017 for $11.2 million, $5.4 million on Destin as a result of twelve months of ownership reflected in 2017
versus eight months in 2016, as well as higher volumes on our Okeanos system for $4.0 million.

In  the  fourth  quarter  of  2017,  a  temporary  delay  of  production  volumes  flowing  into  Delta  House  occurred,  requiring  remedial  work  which  is  scheduled  to  be
completed later in the second quarter of 2018. This has resulted in a reduction in cash distributions from Delta House. On March 11, 2018, the Partnership and
Magnolia,  an  affiliate  of  ArcLight,  entered  into  a  Capital  Contribution  Agreement  by  which  Magnolia  will  provide  additional  capital  and  corporate  overhead
support to the Partnership for the first three quarters of 2018 in an amount up to the difference between the actual cash distribution received by the Partnership on
account of its interest in Delta House and the quarterly cash distribution expected to be received if production flows to Delta House had not been not curtailed.

Segment Gross Margin . Segment gross margin for the year ended December 31, 2017 was $103.7 million compared to $82.3 million for the year ended December
31, 2016 . This increase of $21.4 million was primarily due to earnings in unconsolidated affiliates as noted above under Earnings in Unconsolidated Affiliates.

Direct Operating Expenses . Direct operating expenses for the year ended December 31, 2017 were $17.0 million compared to $10.9 million for the year ended
December 31, 2016 . This increase of $6.1 million was primarily due to $3.9 million incremental expenses associated with our recent acquisitions (VKGS, $2.3
million, and Panther, $1.6 million), $1.5 million in environmental regulatory and compliance costs, and $0.7 million due to rental equipment costs.

Year Ended December 31, 2016 , Compared to Year Ended December 31, 2015

Commodity Sales . Commodity sales for the year ended December 31, 2016 were $6.8 million compared to $13.8 million for the year ended December 31, 2015 .
This decrease of $7.0 million was primarily due to a reduction in the average realized prices for natural gas and condensate of 11.4% and 22.1%, respectively.

Services Revenue. Services revenue for the year ended December 31, 2016 was $40.5 million compared to $21.5 million for the year ended December 31, 2015 .
This  increase  of  $19.0  million  was  primarily  due  to  the  Pascagoula  plant  shutdown  which  required  volumes  to  be  redirected  to  our  High  Point  system,  and
increased fees associated with our acquisition of the Gulf of Mexico Pipeline. The Pascagoula plant is not controlled or owned by the Partnership.

Cost  of  Sales  .  Cost  of  sales  for  the  year  ended  December  31, 2016  was  $3.0  million  compared  to  $9.9  million  for  the  year  ended  December  31, 2015  . This
decrease of $6.9 million was primarily due to lower realized commodity prices, as described above under Commodity Sales.

Earnings in Unconsolidated Affiliates. Earnings in unconsolidated affiliates for the year ended December 31, 2016 were $38.1 million compared to $8.2 million
for the year ended December 31, 2015. This increase of $29.9 million was primarily due to the incremental investments in the Delta House entities in 2016, as well
as the Emerald transaction that occurred in April 2016.

81

Segment Gross Margin . Segment gross margin for the year ended December 31, 2016 was $82.3 million compared to $33.6 million for the year ended December
31, 2015 .  This  increase  of  $48.7  million  was  primarily  due  to  increased  revenues  for  our  Highpoint  system  of  $7.1  million  as  a  result  of  the  shutdown  of  the
Pascagoula plant, increased fees associated with our acquisition of the Gulf of Mexico Pipeline of $12.5 million, incremental earnings of $22.8 million related to
our  investment  in  Delta  House  and  $8.4  million  associated  with  the  offshore  interests  acquired  in  the  Emerald  transaction,  partially  offset  by  a  decrease  in
commodity realized prices.

Direct Operating Expenses . Direct operating expenses for the year ended December 31, 2016 were $10.9 million compared to $9.4 million for the year ended
December 31, 2015 . This increase of $1.5 million was primarily due to the incremental expenses associated with our acquisition of the Gulf of Mexico Pipeline,
partially offset by lower employee costs.

Commodity Sales . Commodity sales for the year ended December 31, 2017 were $15.3 million compared to $14.7 million for the year ended December 31, 2016.
The increase of $0.6 million relates to our refined products and was primarily driven by an increase in butane blending sales pricing at our Caddo Mills for $1.2
million offset by a decrease in butane blending volumes sold at our North Little Rock terminal facility for $0.6 million.

Services Revenue. Services revenue for the year ended December 31, 2017 , was $50.2 million compared to $51.0 million for the year ended December 31, 2016 .
The decrease of $0.8 million was primarily  attributable  to a $3.6 million  reduction  in storage and utilization  at our Cushing terminal from a new contract  with
lower  storage  and  rate  terms  and  a  $0.5  million  decrease  in  throughput  revenue  at  our  North  Little  Rock  terminal  due  to  the  loss  of  a  customer  in  July  2016,
partially offset by a $1.8 million increase in throughput revenues from Caddo Mills facility enhancements and a $1.7 million increase in contracted capacity and
related ancillary services as a result of the Harvey terminal expansion.

Cost  of  Sales.  Cost  of  sales  for  the  year  ended  December  31,  2017  was  $12.9  million  compared  to  $11.6  million  for  the  year  ended  December  31,  2016.  The
increase of $1.3 million was primarily due to higher butane costs.

Segment Gross Margin . Segment gross margin for the year ended December 31, 2017 was $38.0 million compared to $42.9 million for the year ended December
31, 2016 . The decrease of $4.9 million was primarily attributable to a decrease in Cushing storage, higher operating costs at Harvey and higher butane costs offset
by the Harvey expansion and the Caddo Mills facility enhancements discussed above.

Direct Operating Expenses . Direct operating expenses for the year ended December 31, 2017 were $14.6 million compared to $10.8 million for the year ended
December 31, 2016 . The increase of $3.8 million was primarily due to a $2.5 million increase in operating costs at our Harvey terminal, driven by $1.0 million
increase in repairs and maintenance, contractor services, environmental and related costs directly attributable to the Harvey facility expansion, in addition to $0.6
million for security and  supplemental labor.

Year Ended December 31, 2016 , Compared to Year Ended December 31, 2015

Commodity Sales . Commodity sales for the year ended December 31, 2016 were $14.7 million compared to $10.3 million for the year ended December 31, 2015.
The increase of $4.4 million was attributable to an increase in refined products sales related to the addition of butane blending capabilities at our North Little Rock
Terminal in the second quarter of 2015.

Services Revenue. Services revenue for the year ended December 31, 2016 , was $51.0 million compared to $45.0 million for the year ended December 31, 2015 .
The  increase  of  $6.0  million  was  primarily  attributable  to  increases  in  contracted  storage  capacity  due  to  the  expansion  efforts  at  our  Harvey  terminal  of  $5.1
million and $0.7 million from increased refined product storage due to additional blending and injection of additives.

Cost of Sales. Cost of sales for the year ended December 31, 2016 was $11.6 million compared to $8.9 million for the year ended December 31, 2015. The increase
of $2.7 million was primarily due to an increase in butane blending sales volume.

Segment Gross Margin . Segment gross margin for the year ended December 31, 2016 was $42.9 million compared to $36.1 million for the year ended December
31, 2015 . The increase of $6.8 million was primarily attributable to an increase in storage revenue and to a lesser extent margins from refined product sales.

Direct Operating Expenses . Direct operating expenses for the year ended December 31, 2016 were $10.8 million compared to $10.4 million for the year ended
December 31, 2015 . The increase of $0.4 million was related to liability classified as unit-based compensation.

Liquidity and Capital Resources

Overview

Our business is capital intensive and requires significant investment for the maintenance of existing assets and the acquisition and development of new systems and
facilities.

Our principal sources of liquidity include cash from operating activities, borrowings under our Credit Agreement (as defined herein), or through private and public
offerings.  In  addition,  we  may  seek  to  raise  capital  through  the  issuance  of  secured  and  unsecured  senior  notes.  We  also  have  received  occasionally  cash  and
liquidity  support  from  our  sponsor,  ArcLight.  Given  our  historical  success  in  accessing  various  sources  of  liquidity,  we  believe  that  the  sources  of  liquidity
described above will be sufficient to meet our short-term working capital requirements, medium-term maintenance capital expenditure requirements, and quarterly
cash distributions for at least the next four quarters. In the event these sources are not sufficient, we would pursue other sources of cash funding, including, but not
limited to, additional forms of debt or equity financing. In addition, we would reduce non-essential capital expenditures, direct operating expenses and corporate
expenses, as necessary, and our Partnership Agreement allows us to reduce or eliminate quarterly distributions, if required to maintain ongoing operations. We plan
to finance our growth capital expenditures mainly through additional forms of debt or equity financing, as well as proceeds from the sale of non-core assets.

Changes in natural gas, crude oil, NGL and condensate prices and the terms of our contracts may have a direct impact on our generation and use of cash from
operations  due  to  their  impact  on  net  income  (loss),  along  with  the  resulting  changes  in  working  capital.  In  the  past,  we  mitigated  a  portion  of  our  anticipated
commodity price risk associated with the volumes from our gathering

83

and processing activities with fixed price commodity swaps. For additional information regarding our derivative activities, see the information provided under Part
II, Item 7A of this Annual Report, under the caption Quantitative and Qualitative Disclosures about Market Risk .

The  counterparties  to  certain  of  our  commodity  swap  contracts  are  investment-grade  rated  financial  institutions.  Under  these  contracts,  we  may  be  required  to
provide collateral to the counterparties in the event that our potential payment exposure exceeds a predetermined collateral threshold. Collateral thresholds are set
by  us  and  each  counterparty,  as  applicable,  in  the  master  contract  that  governs  our  financial  transactions  based  on  our  and  the  counterparty’s  assessment  of
creditworthiness. The assessment of our position with respect to the collateral thresholds is determined on a counterparty by counterparty basis, and is impacted by
the representative forward price curves and notional quantities under our swap contracts. Due to the interrelation between the representative natural gas and crude
oil forward price curves, it is not practical to determine a single pricing point at which our swap contracts will meet the collateral thresholds as we may transact
multiple commodities with the same counterparty. Depending on daily commodity prices, the amount of collateral posted can go up or down on a daily basis. As of
December 31, 2017, we have not been required to post collateral with our counterparties.

AMID Credit Agreement

On March 8, 2017, we entered into the Second Amended and Restated Credit Agreement, with Bank of America N.A., as Administrative Agent, Collateral Agent
and L/C Issuer, Wells Fargo Bank, National Association, as Syndication Agent, and other lenders or Credit Agreement, which increased our borrowing capacity
from $750.0 million to $900.0 million and provided for an accordion feature that will permit, subject to customary conditions, the borrowing capacity under the
facility to be increased to a maximum of $1.1 billion.

For the years ended December 31, 2017 and 2016, the weighted average interest rate on borrowings under our Credit Agreement and the JPE Revolver (as defined
below)  was  approximately  4.96%  and  4.29%,  respectively.  At  December  31,  2017  and  December  31,  2016,  letters  of  credit  outstanding  under  the  Credit
Agreement were $24.1 million and $7.4 million, respectively. As of December 31, 2017, we had approximately $697.9 million of borrowings, $24.1 million of
letters of credit outstanding under the Credit Agreement and approximately $48.0 million of available borrowing capacity which can be increased up to $178.0
million, conditional upon compliance with future covenants.

As of December 31, 2017, we were in compliance with the covenants included in the Credit Agreement. As of December 31, 2017, our consolidated total leverage
ratio was 5.23 , our consolidated secured leverage ratio was 3.29 and our interest coverage ratio was 3.62 . Our ability to maintain compliance with the leverage
and interest coverage ratios included in the Credit Agreement may be subject to, among other things, the timing and success of initiatives we are pursuing, which
may include expansion capital projects, acquisitions, or drop down transactions, as well as the associated financing for such initiatives. If required, ArcLight, which
controls the General Partner of the Partnership, has confirmed its intent to provide financial support for the Partnership to maintain compliance with the covenants
contained in the Credit Agreement through April 10, 2019. See Note 14 - Debt Obligations, in Part II, Item 8 of this Annual Report.

We use the term “revolving credit facility” or “Credit Agreement,” to refer to our First Amended and Restated Credit Facility and to our Second Amended and
Restated Credit Facility, as the context may require.

JPE Revolver

JPE had a $275.0 million revolving loan, which included a sub-limit of up to $100.0 million for letters of credit with Bank of America, N.A. (the “JPE Revolver”).
The JPE Revolver was scheduled to mature on February 12, 2019, but on March 8, 2017, in connection with the closing of the JPE Merger, the $199.5 million
outstanding balance of the JPE Revolver was paid off in full and terminated. For the years ended December 31, 2017 and 2016, the weighted average interest rate
on borrowings under the JPE Revolver was approximately 2.85% and 2.82%, respectively.

8.50% Senior Unsecured Notes

On  December  28,  2016,  the  Partnership  and  American  Midstream  Finance  Corporation,  our  wholly-owned  subsidiary  (the  “Co-Issuer”  and  together  with  the
Partnership, the “Issuers”), completed the issuance and sale of the $300 million aggregate principal amount of their 8.50% Senior Notes due 2021 (the "8.50%
Senior  Notes").  The  8.50%  Senior  Notes  rank  equal  in  right  of  payment  with  all  existing  and  future  senior  indebtedness  of  the  Issuers,  and  senior  in  right  of
payment  to  any  future  subordinated  indebtedness  of  the  Issuers.  The  8.50%  Senior  Notes  were  issued  at  par  and  provided  approximately  $291.3  million  in
proceeds, after deducting the initial purchasers' discount of $6.0 million and $2.7 million of debt issuance costs. This amount was deposited into escrow

84

pending completion of the JPE Merger and is included in Restricted cash-long term on our consolidated balance sheet as of December 31, 2016.

The 8.50% Senior Notes were offered and sold to qualified institutional buyers in the United States pursuant to Rule 144A under the Securities Act, and to persons,
other than U.S. persons, outside the United States pursuant to Regulation S under the Securities Act. Upon the closing of the JPE Merger and the satisfaction of
other conditions related thereto, the proceeds were used to repay and terminate the JPE Revolver and reduce borrowings under our Credit Agreement.

On  December  19,  2017,  the  Issuers  completed  the  issuance  and  sale  of  an  additional  $125  million  in  aggregate  principal  amount  of  8.50%  Senior  Notes  (the
“Additional Issuance”), net of issuance cost of approximately $3.0 million. The Additional Issuance was offered and sold to qualified institutional buyers in the
United States pursuant to Rule 144A under the Securities Act, and to persons, other than U.S. persons, outside the United States pursuant to Regulation S under the
Securities Act.

The 8.50% Senior Notes will mature on December 15, 2021 and interest on the Additional Issuance will accrue from December 15, 2017. Interest on the 8.50%
Senior Notes is payable in cash semiannually in arrears on each June 15 and December 15, with interest payable on the Additional Issuance commencing June 15,
2018. Interest will be payable to holders of record on the June 1 and December 1 immediately preceding the related interest payment date, and will be computed on
the basis of a 360-day year consisting of twelve 30-day months. Pursuant to the registration rights agreements entered into in connection with the issuances of the
8.50% Senior Notes, additional interest on the 8.50% Senior Notes accrues at 0.25% per annum for the first 90-day period following December 23, 2017 and by an
additional 0.25% per annum with respect to each subsequent 90-day period, up to a maximum additional rate of 1.00% per annum over 8.50%, until we complete
an exchange offer for the 8.50% Senior Notes. See Note 14 - Debt Obligations in Part II, Item 8 of this Annual Report, for further discussion of the 8.50% Senior
Notes.

3.77% Senior Secured Notes

On  September  30,  2016,  Midla  Financing  (“Midla  Financing”)  American  Midstream  (Midla)  LLC  (“Midla”),  and  MLGT  (together  with  Midla,  the  “Note
Guarantors”)  entered  into  the  3.77%  Senior  Note  Purchase  and  Guaranty  Agreement  (the  “Note  Purchase  Agreement”)  with  the  purchasers  party  thereto  (the
“Purchasers”).  Pursuant to the Note Purchase Agreement, Midla Financing issued and sold $60.0 million  in aggregate  principal  amount of 3.77% Senior Notes
(non-recourse) due June 30, 2031 (the “3.77% Senior Notes”) to the Purchasers, which bear interest at an annual rate of 3.77% to be paid quarterly. The average
quarterly principal payment is approximately $1.1 million. Principal on the 3.77% Senior Notes will be paid on the last business day of each fiscal quarter end
which began June 30, 2017. The 3.77% Senior Notes are payable in full on June 30, 2031. The 3.77% Senior Notes were issued at par and provided net proceeds of
approximately $57.7 million after deducting related issuance costs of $2.3 million. The 3.77% Senior Notes are non-recourse to the Partnership.

In connection with the Note Purchase Agreement, the Note Guarantors guaranteed the payment in full of all Midla Financing’s obligations under the Note Purchase
Agreement.  Also,  Midla  Financing  and  the  Note  Guarantors  granted  a  security  interest  in  substantially  all  of  their  tangible  and  intangible  personal  property,
including the membership interests in each Note Guarantor held by Midla Financing, and Financing Holdings pledged the membership interests in Midla Financing
to the Collateral Agent.

Net proceeds from the 3.77% Senior Notes are restricted and have been be used (1) to fund project costs incurred in connection with (a) the construction of the
Midla-Natchez Line (b) the retirement of Midla’s existing 1920’s vintage pipeline (c) the move of our Baton Rouge operations to the MLGT system, and (d) the
reconfiguration of the DeSiard compression system and all related ancillary facilities, (2) to pay transaction fees and expenses in connection with the issuance of
the 3.77% Senior Notes, and (3) for other general corporate purposes of Midla Financing. See Note 14 - Debt Obligations , in Part II, Item 8 of this Annual Report,
for further discussion of the 3.77% Senior Notes.

Acquisition Support and Reimbursement

During 2017, an affiliate of ArcLight agreed and provided distribution support of $34.8 million pursuant to the support agreement that was executed in conjunction
with the JPE Merger. In March 2018, an affiliate of ArcLight agreed to provide quarterly capital contributions, commencing with the quarter ending March 31,
2018 and ending with respect to the quarter ending September 30, 2018, in connection with the temporary curtailment of production flows at Delta House in the
fourth quarter of 2017. The amount of the capital contributions will be agreed, up to the difference between the amount of each quarterly cash distribution received
by us on account of our interest in Delta House and the amount of the corresponding quarterly cash distribution expected to be received if production flows to
Delta House had not been not curtailed.

Working Capital

85

Working  capital  is  the  amount  by  which  current  assets  exceed  current  liabilities  and  is  a  measure  of  our  ability  to  pay  our  liabilities  as  they  become  due.  Our
working  capital  requirements  are  primarily  driven  by  changes  in  accounts  receivable  and  accounts  payable.  These  changes  are  impacted  to  a  certain  extent  by
changes  in  the  prices  of  commodities  that  we  buy  and  sell.  In  general,  our  working  capital  requirements  increase  in  periods  of  rising  commodity  prices  and
decrease in periods of declining commodity prices. However, our working capital needs do not necessarily change at the same rate as commodity prices because
both accounts receivable and accounts payable are impacted by the same commodity prices. In addition, the timing of payments received from our customers or
paid to our suppliers can also cause fluctuations in working capital because we settle with most of our larger suppliers and customers on a monthly basis and often
near the end of the month. We expect that our future working capital requirements will be impacted by these same factors. Our working capital was $ 16.2 million
at December 31, 2017, compared with a working capital deficit of $16.4 million at December 31, 2016.

Year Ended December 31, 2017 Compared to Year Ended December 31, 2016

Operating Activities . Net cash provided by operating activities was $15.0 million for the year ended December 31, 2017, compared to $90.6 million for the year
ended December 31, 2016. The decrease of $75.7 million in cash flows from operating activities resulted primarily from an increase in net loss of $62.8 million,
excluding the $194.6 million of impairment charges, the $36.0 million MPOG acquisition gain and $51.4 million gains on sale of assets and business recorded in
2017; as well as an increase in the change in operating assets and liabilities of $18.0 million.

Investing Activities . Net cash provided by investing activities was $252.3 million for the year ended December 31, 2017, compared to a use of funds of $564.5
million for the year ended December 31, 2016. The increase of cash flows from investing activities resulted primarily from the release of approximately $299.1
million in restricted cash in March 2017 that was recorded since the end of 2016 and held in escrow, the net proceeds from the sale of our Propane Business of
$168.6 million and lower net Acquisitions/Investments and Additions of $88.9 million in 2017, partially offset by lower distributions from unconsolidated affiliates
return of capital for $15.1 million.

Financing Activities . Net cash used by financing activities was $264.2 million for the year ended December 31, 2017, compared to net cash provided by financing
activities of $477.5 million for the year ended December 31, 2016. The decrease in cash flows from financing activities was due primarily to additional net pay
downs on our Credit Agreement of $391.5, lower proceeds from our senior notes of $228.0 million, distributions to our General Partner due to our common control
transactions for $86.3 million and the redemption of our Series D Units of $34.5 million, including distributed accrued PIK, partially offset by $44.3 million related
to our General Partner’s contributions.

Year Ended December 31, 2016 , Compared to Year Ended December 31, 2015

Operating Activities . Net cash provided by operating activities was $90.6 million for the year ended December 31, 2016 , compared to $87.0 million for the year
ended December 31, 2015. Net cash provided by operating activities for the year ended December 31, 2016 , compared to December 31, 2015 increased by $3.6
million mainly driven by a reduction in net loss of $18.3 million, excluding the $148.5 million goodwill impairment charge recorded in 2015, offset by a decrease
in the change in operating assets and liabilities of $10.1 million.

Investing Activities .  Net cash  used  in  investing  activities  was $564.5  million  for  the  year  ended  December  31, 2016, compared  to  $250.8 million  for the  year
ended December 31, 2015. Cash used in investing activities for the year ended December 31, 2016 increased by $313.7 million period over period primarily due to
the change in restricted cash of $325.6 million as a result of the issuance of our 8.50% Senior Notes and our 3.77% Senior Notes and an increase in investments in
unconsolidated affiliates specifically for our interests in the Emerald Transactions and additional interests in Delta House Investment of $84.5 million.

86

 
 
 
 
 
 
 
   
   
   
 
 
These increases were partially offset by a $60.2 million decrease in capital expenditures and $30.5 million of higher cash distributions received from investments
in unconsolidated affiliates as a return of capital.

Financing Activities .  Net  cash  provided  by  financing  activities  was $477.5  million  for  the  year  ended  December  31, 2016, compared  to  net  cash  provided  by
financing activities of $162.0 million for the year ended December 31, 2015. Cash provided by financing activities for the year ended December 31, 2016 increased
by $315.5 million period over period primarily  due proceeds from the 8.50% Senior Notes of $294.0 million , proceeds from the 3.77% Senior Notes of $60.0
million , partially offset by lower borrowings primarily on our revolving credit agreements of $46.2 million.

Distribution to our unitholders

During the year ended December 31, 2017, we paid a total of approximately $89.4 million of distributions to our unitholders. This was made possible primarily by
$15.0 million of cash generated from operating activities, and approximately $90.8 million of distributions relating to our unconsolidated affiliates.

Off-Balance Sheet Arrangements

We may enter into off-balance sheet arrangements and transactions that can give rise to material off-balance sheet obligations. At December 31, 2017, our material
off-balance  sheet  arrangements  and  transactions  included  operating  lease  arrangements  and  service  contracts.  There  are  no  other  transactions,  arrangements,  or
other  relationships  associated  with  our  investments  in  unconsolidated  affiliates  or  related  parties  that  are  reasonably  likely  to  materially  affect  our  liquidity  or
availability of, or requirements for, capital resources. At December 31, 2017, our off-balance sheet arrangements totaled $163.7 million.

Capital Requirements

The energy business is capital intensive, requiring significant investment for the maintenance of existing assets and the acquisition
and development of new systems and facilities. We categorize our capital expenditures as either:

• maintenance capital expenditures, which are cash expenditures (including expenditures for the addition or improvement to, or the replacement of, our
capital assets) made to maintain our operating income or operating capacity; or

• expansion capital expenditures, incurred for acquisitions of capital assets or capital improvements that we expect will increase our operating income or
operating capacity over the long term.

Historically, our maintenance capital expenditures have not included all capital expenditures required to maintain volumes on our systems. It is customary in the
regions  in  which  we operate  for  producers  to bear  the  cost  of  well  connections,  but  we cannot  be  assured  that  this  will be  the  case  in  the  future.  Although  we
classified  our  capital  expenditures  as  expansion  and  maintenance,  we  believe  those  classifications  approximate,  but  do  not  necessarily  correspond  to,  the
definitions of estimated maintenance capital expenditures and expansion capital expenditures under our Partnership Agreement.

For  the  year  ended  December  31,  2017,  capital  expenditures  totaled  $117.1  million,  including  expansion  capital  expenditures  of  $105.4  million,  maintenance
capital  expenditures  of  $8.9  million  and  reimbursable  project  expenditures  (capital  expenditures  for  which  we  expect  to  be  reimbursed  for  all  or  part  of  the
expenditures  by a  third  party)  of  $2.8  million.  For  the  year  ended  December  31,  2016, capital  expenditures  totaled  $147.8 million,  including  expansion  capital
expenditures of $137.3 million, maintenance capital expenditures of $6.8 million and reimbursable project expenditures (capital expenditures for which we expect
to be reimbursed for all or part of the expenditures by a third party) of $3.7 million. Of these capital expenditures amounts, $3.1 million and $3.5 million for the
year ended December 31, 2017 and 2016, respectively, were incurred for the Propane Business that we disposed on September 1, 2017, as discussed in Note 4 -
Dispositions, in Part II, Item 8 of this Annual Report .

87

Integrity Management

Certain  operating  assets  require  an  ongoing  integrity  management  program  which  is  associated  high  consequence  areas  ("HCA")  that  require  on-going  testing
pursuant to the U.S. Department of Transportation ("DOT") regulations. These DOT regulations require transportation pipeline operators to implement continuous
integrity management programs over a seven-year cycle, which varies from asset to asset and different segments within those asset areas and is date-stamped from
the day the energized baseline is established for each operating asset. Our total program addresses approximately 112 HCA as of December 31, 2017. We expect to
incur approximately $2.0 million annual cost in integrity management testing expenses. The amount may increase as our HCA mileage may increase through future
acquisitions.

Distributions

We  intend  to  pay a  quarterly  distribution  for  the  foreseeable  future  although  we do not  have  a legal  obligation  to  make  distributions  except  as  provided  in  our
Partnership Agreement.

On January 26, 2018, we announced that the Board of Directors of our General Partner declared a quarterly cash distribution of $0.4125 per American Midstream
common unit for the fourth quarter ended December 31, 2017, or $1.65 per common unit on an annualized basis. The cash distribution was paid on February 14,
2018, to unitholders of record as of the close of business on February 7, 2018.

Impact of Seasonality

Results  of  operations  in  our  Natural  Gas  Transportation  Services  segment  are  directly  affected  by  seasonality  due  to  higher  demand  for  natural  gas  during  the
winter  months,  primarily  driven  by  our  LDC  customers.  On  our  AlaTenn  system,  we  offer  some  customers  seasonally-adjusted  firm  transportation  rates  that
require customers to reserve capacity at rates that are higher in the period from

88

 
 
 
 
 
 
   
   
   
   
   
   
   
 
 
 
 
 
 
October to March compared to other times of the year. On our Midla system, we offer customers seasonally-adjusted firm transportation reservation volumes that
allow customers to reserve more capacity during the period from October to March compared to other times of the year. The combination of seasonally-adjusted
rates and reservation volumes, as well as higher volumes overall, result in higher revenue and segment gross margin in our Natural Gas Transportation Services
segment  during  the  period  from  October  to  March  compared  to  other  times  of  the  year.  We  generally  do  not  experience  seasonality  in  our  Gas  Gathering  and
Processing Services and Terminalling Servicing segments.

The volume of product that is handled, transported, throughput or stored in our refined products terminals is directly affected by the level of supply and demand in
the wholesale markets served by our terminals. Overall supply of refined products in the wholesale markets is influenced by the absolute prices of the products, the
availability of capacity on delivering pipelines and vessels, fluctuating refinery margins and the market’s perception of future product prices. Although demand for
gasoline typically peaks during the summer driving season, which extends from April to September, and declines during the fall and winter months, most of the
revenues generated at our refined products terminals do not experience any effects from such seasonality. However, the butane blending operations at our refined
products terminals are affected by seasonality because of federal regulations governing seasonal gasoline vapor pressure specifications. Accordingly, we expect
that the revenues we generate from butane blending will be highest in the winter months and lowest in the summer months.

The  butane  blending  operations  at  our  refined  products  terminals  are  affected  by  seasonality  because  of  federal  regulations  governing  seasonal  gasoline  vapor

Critical Accounting Policies and Estimates

The preparation of financial statements in accordance with GAAP requires our management to make estimates and assumptions that affect the reported amounts of
assets and liabilities as well as the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and
expenses during the period. Actual results could differ from these estimates. The policies and estimates discussed below are considered by our management to be
critical to an understanding of the financial statements because their application requires the most significant judgments from management in estimating matters for
financial reporting that are inherently uncertain. See the description of our accounting policies in the notes to the financial statements for additional information
about our critical accounting policies and estimates.

Use  of  Estimates.  When  preparing  consolidated  financial  statements  in  conformity  with  GAAP,  management  must  make  estimates  and  assumptions  based  on
information  available  at  the  time.  These  estimates  and  assumptions  affect  the  reported  amounts  of  assets,  liabilities,  revenues  and  expenses,  as  well  as  the
disclosures of contingent assets and liabilities as of the date of the financial statements. Estimates and assumptions are based on information available at the time
such estimates and assumptions are made. Adjustments made with respect to the use of these estimates and assumptions often relate to information not previously
available. Uncertainties with respect to such estimates and assumptions are inherent in the preparation of financial statements. Estimates and assumptions are used
in,  among  other  things,  i)  estimating  unbilled  revenues,  product  purchases  and  operating  and  general  and  administrative  costs,  ii)  developing  fair  value
assumptions, including estimates of future cash flows and discount rates, iii) analyzing long-lived assets, goodwill and intangible assets for possible impairment,
iv) estimating the useful lives of assets and v) determining amounts to accrue for contingencies, guarantees and indemnifications. Actual results, therefore, could
differ materially from estimated amounts.

Property,  Plant  and  Equipment.  We  capitalize  expenditures  related  to  property,  plant  and  equipment  that  have  a  useful  life  greater  than  one  year.  We  also
capitalize expenditures that improve or extend the useful life of an asset. Maintenance and repair costs, including any planned major maintenance activities, are
expensed as incurred.

We record property, plant, and equipment at cost and recognize depreciation expense on a straight-line basis over the related estimated useful lives of the assets
which range from 3 to 40 years. Our determination of the useful lives of property, plant and equipment requires us to make various assumptions, including the
supply of and demand for hydrocarbons in the markets served
by our assets, normal wear and tear of the facilities, and the extent and frequency of maintenance programs. We record depreciation using the group method of
depreciation, which is commonly used by pipelines, utilities and similar assets.

We classify long-lived assets to be disposed of through sales that meet specific criteria as held for sale. We cease depreciating those assets effective on the date the
asset is classified as held for sale. We record those assets at the lower of their carrying value or the estimated fair value less the cost to sell. Until the assets are
disposed of, our estimate of fair value is re-determined when related events or circumstances change.

89

Impairment of Long Lived Assets. We evaluate the recoverability of our property, plant and equipment and intangible assets with definite lives when events or
circumstances  indicate  we may not recover  the carrying amount of the assets. We continually monitor our operations,  the market, and business environment to
identify  indicators  that  could  suggest  an  asset  or  asset  group  may  not  be  recoverable.  We  evaluate  the  asset  or  asset  group  for  recoverability  by estimating  the
undiscounted future cash flows expected to be derived from their use and disposition. These cash flow estimates require us to make projections and assumptions
for many years into the future for pricing, demand, competition, operating cost, contract renewals, and other factors. An asset or asset group is considered impaired
when  the  estimated  undiscounted  cash  flows  are  less  than  the  carrying  amount.  In  that  event,  an  impairment  loss  is  recognized  to  the  extent  that  the  carrying
amount of the asset or asset group exceeds its fair value as determined by quoted market prices in active markets or present value techniques. The determination of
fair values using present value techniques requires us to make projections and assumptions regarding future cash flows and weighted average cost of capital. Any
changes  we  make  to  these  projections  and  assumptions  could  result  in  significant  revisions  to  our  evaluation  of  the  recoverability  of  our  property,  plant  and
equipment and the recognition of an impairment loss in our consolidated statements of operations.

Goodwill  and Intangible  Assets.  We  record  goodwill  for  the  excess  of  the  cost  of  an  acquisition  over  the  fair  value  of  the  net  assets  of  the  acquired  business.
Goodwill is reviewed for impairment at least annually or more frequently if an event or change in circumstance indicates that an impairment may have occurred.
We first assess qualitative factors to evaluate whether it is more likely than not that an impairment has occurred and it is therefore necessary to perform the one-
step  goodwill  impairment  test.  If  the  one-step  goodwill  impairment  test  indicates  that  the  goodwill  is  impaired,  an  impairment  loss  is  recorded,  which  is  the
difference between carrying value and fair value.

We  record  the  estimated  fair  value  of acquired  customer  contracts,  relationships  and dedicated  acreage  agreements  as  intangible  assets.  These intangible  assets
have definite lives and are subject to amortization on a straight-line basis over their economic lives, currently ranging between 5 years and 30 years. We assess
intangible assets for impairment together with related underlying long-lived assets whenever events or changes in circumstances indicate that the carrying amount
of an asset may not be recoverable.

Investment  in  Unconsolidated  Affiliates.  We  hold  membership  interests  in  entities  that  own  and  operate  natural  gas  pipeline  systems  and  NGL  and  crude  oil
pipelines in and around Louisiana, Alabama, Mississippi and the Gulf of Mexico. While we have significant influence over these entities, we do not control them
and therefore, they are accounted for using the equity method and are reported in Investment in unconsolidated affiliates in the consolidated balance sheets. We
evaluate the recoverability of these investments on a regular basis and recognize impairment write downs if we determine a loss in value represents an other than
temporary decline.

Asset Retirement Obligations. Asset retirement obligations ("ARO") are legal obligations associated with the retirement of tangible long-lived assets that result
from the asset's acquisition, construction, development and operation. An ARO is initially measured at its estimated fair value. Upon initial recognition, we also
record an increase to the carrying amount of the related long-lived asset. We depreciate the asset using the straight-line method over the period during which it is
expected to provide benefits. After initial recognition, we revise the ARO to reflect the passage of time and for changes in the estimated amount or timing of cash
flows.

We have legal obligations requiring us to decommission our offshore pipeline systems at retirement. In certain rate jurisdictions, we are permitted to include annual
charges for removal costs in the regulated cost of service rates we charge our customers. Additionally, legal obligations exist for certain of our onshore right-of-
way  agreements  due  to  requirements  or  landowner  options  to  compel  us  to  remove  the  pipe  at  final  abandonment.  Sufficient  data  exists  with  certain  onshore
pipeline  systems  to  reasonably  estimate  the  cost  of  abandoning  or  retiring  a  pipeline  system.  However,  in  some  cases,  there  is  insufficient  information  to
reasonably determine the timing and/or method of settlement for purposes of estimating the fair value of the asset retirement obligation. In these cases, the asset
retirement  obligation  cost  is  considered  indeterminate  because  there  is  no  data  or  information  that  can  be  derived  from  past  practice,  industry  practice,
management's experience, or the asset's estimated economic life. The useful lives of most pipeline systems are primarily derived from available supply resources
and  ultimate  consumption  of  those  resources  by  end  users.  Variables  can  affect  the  remaining  lives  of  the  assets  which  preclude  us  from  making  a  reasonable
estimate of the asset retirement obligation. Indeterminate asset retirement obligation costs will be recognized in the period in which sufficient information exists to
reasonably estimate potential settlement dates and methods.

Revenue Recognition. We  recognize  revenue  from  the  sale  of  commodities  (e.g.,  natural  gas,  crude  oil,  NGLs  or  condensate)  as  well  as  from  the  provision  of
gathering, processing, transportation or storage services when all of the following criteria are met: i) persuasive evidence of an exchange arrangement exists, ii)
delivery has occurred or services have been rendered, iii) the price is fixed or determinable, and iv) collectability is reasonably assured. We recognize revenue from
the sale of commodities and the related cost of product sold on a gross basis for those transactions where we act as the principal and take title to commodities that
are purchased for resale. See discussion regarding the new revenue recognition standard, effective January 1, 2018 in Note 2 - New Accounting Pronouncements ,
Part II, Item 8 of this Annual Report.

Price  Risk  Management  Activities.  We  have  structured  our  hedging  activities  in  order  to  minimize  our  commodity  pricing  and  interest  rate  risks  and  to  help
maintain compliance with certain financial covenants in our credit agreement. These hedging activities rely upon forecasts of our expected operations and financial
structure. If our operations or financial structure are significantly different from these forecasts, we could be subject to adverse financial results as a result of these
hedging  activities.  We  mitigate  this  potential  exposure  by  retaining  an  operational  cushion  between  our  forecast  transactions  and  the  level  of  hedging  activity
executed.

We used mark-to-market accounting for our commodity hedges and interest rate swaps. We record monthly realized gains and losses on hedge instruments based
upon  cash  settlements  information.  The  settlement  amounts  vary  due  to  the  volatility  in  the  commodity  market  prices  throughout  each  month.  We  also  record
unrealized gains and losses for the net change in the mark-to-market valuation of the hedges.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

We are exposed to certain market risks that are inherent in our financial instruments and arise from changes in commodity prices and interest rates. A discussion of
our market risk exposure in financial instruments is presented below.

Commodity Price Risk

Overview

We are exposed to the impact of market fluctuations in the prices of natural gas, crude oil, NGLs and condensate in our Gas Gathering and Processing Services
segment. Both our profitability and our cash flow are affected by volatility in the prices of these commodities. Natural gas, crude oil and NGL prices are impacted
by changes in the supply and demand for these energy commodities, as well as market uncertainty. For a discussion of the volatility of natural gas, crude oil, and
NGL prices, see Item 1A - Risk Factors . Adverse effects on our cash flow from reductions in natural gas, crude oil and NGL prices could adversely affect our
operating cash flows and our ability to make distributions to unitholders. We manage this commodity price exposure through an integrated strategy that includes
management  of  our  contract  portfolio,  optimization  of  our  assets,  and  the  use  of  derivative  contracts.  Our  overall  direct  exposure  to  movements  in  natural  gas
prices is minimal as a result of natural hedges inherent in our current contract portfolio. Natural gas prices, however, can also affect our profitability indirectly by
influencing the level of drilling activity in our areas of operation. We are a net seller of NGLs, and as such our financial results are exposed to fluctuations in NGLs
pricing.

To minimize the effect of commodity prices and maintain our cash flow and the economics of our development plans, we enter into commodity hedge contracts
from  time  to  time.  The  terms  of  the  contracts  depend  on  various  factors,  including  management's  view  of  future  commodity  prices,  acquisition  economics  on
purchased assets and future financial commitments. This hedging program is designed to mitigate the effect of commodity price downturns while allowing us to
participate  in  some  commodity  price  upside.  Management  regularly  monitors  the  commodity  markets  and  financial  commitments  to  determine  if,  when,  and  at
what level commodity hedging is appropriate in accordance with policies that are established by the Board of Directors of our General Partner. Historically, the
commodity derivatives are in the form of swaps and collars.

We enter into commodity contracts with counterparties. We may be required to post collateral with our counterparties in connection with our derivative positions.

Commodity Price Risk per Segment

• Gas Gathering and Processing segment . We purchase and take title to a portion of the NGLs that we sell, which may expose us to changes in the price
of NGLs in our sales markets. We manage this commodity price risk by limiting our net open positions and through the concurrent purchase and sale of
like quantities of NGLs that are intended to lock in positive margins based on the timing, location or quality of the crude oil purchased and delivered .

91

•

•

•

Liquid Pipelines and Services segment. We purchase and take title to a portion of the crude oil that we sell, which may expose us to changes in the price
of crude oil in our sales markets. We manage this commodity price risk by limiting our net open positions and through the concurrent purchase and sale of
like quantities of crude oil that are intended to lock in positive margins based on the timing, location or quality of the crude oil purchased and delivered.

Terminalling Services segment. We sell excess volumes of refined products and our gross margin could be impacted by changes in the market prices for
these sales. We may execute forward sales contracts or financial swaps to reduce the risk of commodity price changes in this segment.

Natural Gas Transportation Services and Offshore Pipelines and Services segments . We do not take title to the products we transport and therefore
have no direct commodity price exposure.

During 2016, we entered into several commodity contracts with financial counterparties to hedge our 2016 exposure to commodity prices. Due to our overall low
commodity exposure relative to fee-based and fixed-margin contract portfolio, management seeks to opportunistically enter into commodity contracts to hedge our
natural gas, NGL and crude oil exposure.

We have entered into short term contracts in 2017 to hedge crude oil and NGL exposure and they had all expired as of December 31, 2017. We also have entered
into contracts to hedge a portion of our NGL and crude oil exposure in 2018.

As of December 31, 2017 , we have not been required to post collateral with our counterparties. The counterparties are not required to post collateral with us in
connection  with  their  derivative  positions.  Netting  agreements  are  in  place  with  our  counterparties  that  permit  us  to  offset  our  commodity  derivative  asset  and
liability positions.

Interest Rate Risk

Overview

Our revolving credit facility bears interest at a variable rate and exposes us to interest rate risk. From time to time, we may use certain derivative instruments to
hedge our exposure to variable interest rates. For the year ended December 31, 2017 , we had exposure to changes in interest rates on our indebtedness associated
with our Credit Agreement. To manage the impact of the interest rate risk associated with our Credit Agreement, we enter into interest rate swaps from time to
time, effectively converting a portion of the cash flows related to our long-term variable rate debt into fixed rate cash flows. We do not hold or purchase financial
instruments or derivative financial instruments for trading purposes.

Although the credit markets have recently experienced historical lows in interest rates, interest rates have increased recently and may continue to increase in the
near future. As the overall economy strengthens, it is possible that monetary policy will begin to tighten, resulting in higher interest rates. Future interest rates on
floating rate credit facilities and future debt offerings could be higher than current levels, causing our financing costs to increase accordingly.

As of December 31, 2017 , we had a combined notional principal amount of $550.0 million of variable to fixed interest rate swap agreements. As of December 31,
2017, the maximum length of time over which we have hedged a portion of our exposure due to interest rate risk is through December 31, 2022.

Sensitivity Analysis

Based on our unhedged interest rate exposure to variable rate debt outstanding as of December 31, 2017 , a hypothetical increase or decrease in interest rates by
1.0% would have changed our interest expense by $1.5 million for the year ended December 31, 2017 .

None.

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures that are designed to provide reasonable assurance that information required to be disclosed by us in the reports that
we  file  or  submit  to  the  SEC  under  the  Securities  Exchange  Act  of  1934,  as  amended  (the  “Exchange  Act”),  is  recorded,  processed,  summarized  and  reported
within the time periods specified by the SEC’s rules and forms, and that such information is accumulated and communicated to the management of our General
Partner, including our General Partner’s principal executive and principal financial officers as appropriate to allow timely decisions regarding required disclosure.

As of the end of the period covered by this report, we carried out an evaluation, under the supervision of the principal executive officer and principal financial
officer of our General Partner, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-
15(e)  of  the  Exchange  Act).  Based  on  our  evaluation,  our  principal  executive  officer  and  principal  financial  officer  concluded  that  the  Partnership’s  disclosure
controls and procedures were not effective as of December 31, 2017 as a result of the material weaknesses in our internal control over financial reporting described
below.

Despite the material weaknesses, our principal executive officer and principal financial officer have concluded that the financial statements included in this report
fairly present in all material respects our financial condition, results of operations and cash flows for the periods presented.

Inherent Limitations of Internal Controls

Our management does not expect that our disclosure controls and procedures will prevent or detect all errors and all fraud. A control system, no matter how well
conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Because of the inherent limitations
in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Partnership have
been  prevented  or  detected.  These  inherent  limitations  include  the  realities  that  judgments  in  decision-making  can  be  faulty,  and  that  breakdowns  can  occur
because of simple errors or mistakes. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by
management override of the controls. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and
there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Management monitors the Partnership’s
disclosure controls and procedures and makes modifications, as necessary, with the intent that the disclosure controls and procedures will be adequately designed
and operating effectively to prevent or detect material misstatements to its consolidated financial statements and to deter fraud.

Management’s Annual Report on Internal Control over Financial Reporting

Management of our General Partner is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Exchange Act
Rules 13a-15(f) and 15d-15(f)). The Partnership’s internal control over financial reporting was designed to provide reasonable assurance regarding the reliability of
financial reporting and preparation of financial statements for external purposes in accordance with generally accepted accounting principles.

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.

Management,  under  the  supervision  of  the  principal  executive  officer  and  principal  financial  officer  of  our  General  Partner,  assessed  the  effectiveness  of  the
Partnership’s  internal  control  over  financial  reporting  as  of  December  31,  2017,  based  on  criteria  set  forth  in  Internal  Control  -  Integrated  Framework  (2013)
issued by the Committee of Sponsoring Organizations of the Treadway Commission. This assessment identified material weaknesses in our internal control over
financial reporting. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable
possibility that a material misstatement of the Partnership’s annual or interim financial statements will not be prevented or detected on a timely basis. As a result of
these material weaknesses, management has concluded that our internal control over financial reporting was not effective as of December 31, 2017.

93

Management  has  identified  the  following  control  deficiencies  that  constituted  material  weaknesses  in  our  internal  control  over  financial  reporting  as  of
December 31, 2017:

We did not maintain an effective control environment as we lacked sufficient oversight of activities related to our internal control over financial reporting and had
an  insufficient  complement  of  resources  with  an  appropriate  level  of  accounting  knowledge,  expertise  and  training  commensurate  with  our  financial  reporting
requirements.  This  material  weakness  contributed  to  additional  material  weaknesses,  as  the  Partnership  did  not  design  and  maintain  effective  controls  over:
verifying that complex, non-routine transactions were recorded appropriately, which such control deficiency resulted in out-of-period adjustments recorded to the
income  statement  in  the  fourth  quarter  of  2016  and  a  revision  to  the  2015  balance  sheet  and  cash  flows;  all  financial  statement  assertions  of  revenue  and
receivables, specifically the review of the accounting for certain contracts, the review that price, volume and other key contractual terms used to record revenue are
consistent  with  the  terms  of  arrangement  and  the  review  that  revenue  is  recorded  in  the  proper  period,  which  such  control  deficiency  resulted  in  immaterial
adjustments  to  the  2017  consolidated  financial  statements;  all  financial  statement  assertions  related  to  acquisitions  and  divestitures,  specifically  verifying  the
existence, rights and obligations associated with assets acquired and liabilities assumed, reviewing the valuation of the purchase price allocation and reviewing the
completeness and accuracy of related disclosures, which such control deficiency resulted in immaterial adjustments to the 2017 consolidated financial statements;
the  period-end  financial  reporting  process,  specifically  the  review  of  account  reconciliations  and  financial  statement  analyses  to  support  the  completeness  and
accuracy  of  the  consolidated  financial  statements  and  disclosures,  which  such  control  deficiency  resulted  in  immaterial  adjustments  to  the  2017  consolidated
financial statements; and the accuracy and valuation of asset retirement obligations, goodwill, other intangible assets and finite-lived assets, specifically the review
of  the  model,  data,  assumptions  and  calculations  used  in  determining  the  estimated  asset  retirement  obligation  and  in  impairment  tests,  and  the  related
identification  of  changes  in  events  and  circumstances  that  indicate  it  is  more  likely  than  not  that  an  impairment  indicator  has  occurred,  which  such  control
deficiency resulted in adjustments to the accounting for asset retirement obligations and impairments in goodwill, other intangible assets and finite-lived assets for
the year ended 2017. Additionally, these material weaknesses could result in a misstatement of substantially all of the financial statement accounts and disclosures
that would result in a material misstatement to the annual or interim consolidated financial statements that would not be prevented or detected.

Additionally, we did not maintain effective controls over certain information technology ("IT") general controls for a significant application used in the preparation
of our financial statements. Specifically, we did not maintain user access controls to ensure appropriate segregation of duties and that adequately restrict user and
privileged  access  to  the  financial  application,  programs,  and  data  to  appropriate  Partnership  personnel.  These  IT  deficiencies  did  not  result  in  a  material
misstatement to the financial statements, however, the deficiencies, when aggregated, could impact our ability to maintain effective segregation of duties, as well
as maintain effective IT-dependent controls (such as automated controls that address the risk of a material misstatement to one or more assertions, along with the
IT controls and underlying data that support the effectiveness of system-generated data and reports), which could result in misstatements of substantially all of the
financial statement accounts and disclosures, resulting in a material misstatement to the annual or interim consolidated financial statements that otherwise would
not be prevented or detected.

On March 8, 2017, we completed the acquisition of JPE. As a result, management excluded JPE from its assessment of internal control over financial reporting.
JPE represents approximately 21.9% of the total assets and 51.4% of net revenues of the related financial statement amounts as of and for the year ended December
31, 2017, respectively.

PricewaterhouseCoopers LLP, our independent registered public accounting firm that audited the consolidated financial statements included in this Annual Report
on  Form  10-K,  also  audited  the  effectiveness  of  the  Partnership’s  internal  control  over  financial  reporting  as  of  December  31,  2017,  as  stated  in  their  report
included on page F-1 of this Annual Report.

Material Weakness Remediation

At December 31, 2016, we identified a material weakness in our internal controls over the level of accounting knowledge, expertise and training commensurate
with our financial reporting requirements. This material weakness was not remediated at December 31, 2017. Management is actively engaged in the planning for,
and implementation of, remediation efforts to address the material weaknesses identified herein. Specifically, we are taking numerous steps that we believe will
address  the underlying  causes  of  the  material  weaknesses,  primarily  through  the  hiring  of  additional  personnel  with  expertise  in  technical  accounting,  financial
reporting and internal controls, the enhancement of our training programs, the enhancement of our controls and internal review procedures and the implementation
and integration of adequate information technology systems.

While  plans  have  been  made  to  enhance  our  internal  control  over  financial  reporting  relating  to  the  material  weaknesses,  management  is  still  in  the  process  of
implementing and testing these processes and procedures and additional time is required to complete implementation and to assess and ensure the sustainability of
these procedures. Management believes these actions will be effective in remediating the material weaknesses described above and management will continue to
devote significant time and

94

attention to these remediation efforts. However, the material weaknesses cannot be considered remediated until the applicable remediated controls operate for a
sufficient period of time and management has concluded, through testing, that these controls are operating effectively.

Changes in internal control over financial reporting

There were no changes in internal control over financial reporting that occurred during the three months ended December 31, 2017 that have materially affected, or
are reasonably likely to materially affect, our internal control over financial reporting.

The  certifications  of  our  principal  executive  officer  and  principal  financial  officer  pursuant  to  Exchange  Act  Rules  13a-14(a)  and  15d-14(a)  are  filed  with  this
Annual  Report  as  Exhibits  31.1  and  31.2.  The  certifications  of  our  principal  executive  officer  and  principal  financial  officer  pursuant  to  18  U.S.C.  1350  are
furnished with this Annual Report as Exhibits 32.1 and 32.2.

Item 9B. Other Information

The Partnership discloses the following pursuant to Item 2.06 of Form 8-K:

In the course of the preparation, review and audit of the financial statements required to be included in this Annual Report, management determined that certain
impairments to property, plant and equipment and to goodwill were probably required under general accepted accounting principles applicable to the Partnership. 
As  the  Partnership  worked  to  finalize  the  total  amount  of  such  impairments,  on  or  about  April  4,  2018,  management  concluded  its  impairment  analysis  and
determined  that  such  impairments  would  be  material.    Please  see  “Management’s  Discussion  and  Analysis  of  Financial  Condition  and  Results  of  Operations  -
Liquidity and Capital Resources” in Part II, Item 7 of this Annual Report and Note 9 - Property, Plant and Equipment, Net and Note 10 - Goodwill and Intangible
Assets, Net, both  in  Part  II,  Item  8  in  this  Annual  report  for  additional  information.    The  Partnership  does  not  expect  that  these  impairments  will  result  in  any
current or future cash expenditures.

The Partnership discloses the following pursuant to Item 3.01 of Form 8-K:

On April 3, 2018, the Partnership received an expected notice from the NYSE stating that the Partnership is not in compliance with the NYSE’s continued listing
requirements under the timely filing criteria outlined in Section 802.01E of the NYSE Listed Company Manual due to the delay in filing this Annual Report. The
NYSE informed the Partnership that, under the NYSE’s rules, the Partnership had six months from April 2, 2018 to file this Annual Report with the SEC in order
to  cure  the  noncompliance  with  the  NYSE’s  requirement  to  timely  file  all  annual  and  quarterly  reports.  With  the  filing  of  this  Annual  Report,  the  Partnership
believes it is now in compliance with the NYSE’s listing standards.

Item 10. Directors, Executive Officers and Corporate Governance

PART III

We do not have directors or officers, which is commonly the case with publicly traded partnerships. We are managed by the directors and executive officers of our
General Partner, American Midstream GP, LLC. Our General Partner is not elected by our unitholders and will not be subject to re-election in the future. HPIP and
AMID GP Holdings, LLC, a wholly owned subsidiary of Magnolia Infrastructure Holdings, LLC, own all of the membership interests in our General Partner. Our
General  Partner  has  a  board  of  directors  (the  "Board"),  and  our  unitholders  are  not  entitled  to  elect  the  directors  or  directly  or  indirectly  participate  in  our
management or operations. Our General Partner owes certain fiduciary duties to our unitholders. Our General Partner is liable, as General Partner, for all of our
debts  (to  the extent  not  paid from  our  assets),  except  for  indebtedness  or other  obligations  that  are  made  specifically  nonrecourse  to it. Whenever  possible,  we
intend to incur indebtedness that is nonrecourse to our General Partner.

Our Partnership Agreement provides for the Board of Directors of our General Partner to designate a Conflicts Committee ("Conflicts Committee"), as delegated
by the Board as circumstances warrant, to review conflicts of interest between us and our General Partner or between us and affiliates of our General Partner. If the
Board submits a matter to the Conflicts Committee, which will consist solely of independent directors, for their review and approval, the Conflicts Committee will
determine if the resolution of a conflict of interest that has been presented to it by the Board is fair and reasonable to us. The members of the Conflicts Committee
may not be executive officers or employees of our General Partner or directors, executive officers or employees of its affiliates. In addition, the members of the
Conflicts Committee must meet the independence and experience standards established by the NYSE and the Exchange Act for service on an audit committee of a
board of directors. Any matters approved by the Conflicts Committee will be conclusively deemed to be fair and reasonable to us and not a breach by our General
Partner  of  any  duties  it  may  owe  us  or  our  unitholders.  In  addition,  the  Board  has  an  Audit  Committee  ("Audit  Committee"),  that  complies  with  the  NYSE
requirements and oversees risk management activities and a compensation committee ("Compensation Committee").

Even though most companies listed on the NYSE are required to have a majority of independent directors serving on the board of directors of the listed company,
the NYSE does not require a listed limited partnership like us to have a majority of independent directors on the Board.

Our General Partner has adopted a Code of Business Conduct and Ethics, or Code of Ethics, that applies to the directors, officers and employees of our General
Partner. If our General Partner amends the Code of Ethics or grants a waiver, including an implicit waiver, for the Code of Ethics, we will disclose the information
on our website. Our General Partner has also adopted Corporate Governance Guidelines that outline the important policies and practices regarding our governance.

All of the senior officers of our General Partner devote a sufficient portion of their time to overseeing the management, operations, corporate development and
future acquisition initiatives of our business; however, they also devote a portion of their time to overseeing the management, operations, corporate development
and future acquisition initiatives of our General Partner, which has separate ongoing business operations.

The non-management members of our General Partner's board of directors meet in executive sessions without management participation at least quarterly. These
directors  do  not  constitute  a  committee  of  the  Board  and  therefore  do  not  take  action  at  such  sessions,  although  the  participating  directors  may  make
recommendations for consideration by the full board.

Interested parties may communicate directly with the independent directors by submitting a communication in an envelope marked "Confidential" addressed to the
"Independent Members of the Board of Directors" in the care of the Secretary of our General Partner at: American Midstream GP, LLC, 2103 CityWest Boulevard,
Building #4, Suite 800, Houston, Texas 77042.

We make available free of charge, within the "Investor Relations—Corporate Governance" section of our website at http://www.americanmidstream.com, and in
print to any unitholder who so requests, the Code of Ethics and our Corporate Governance Guidelines. Unitholders may request a printed copy of these governance
materials  or any exhibit  to this report  by writing to the  Secretary,  American  Midstream  GP, LLC, 2103 CityWest Boulevard,  Building #4, Suite 800, Houston,
Texas 77042. The information contained on, or connected to, our website is not incorporated by reference into this Annual Report and should not be considered
part of this or any other report that we file with or furnish to the SEC.

The independent directors on our Board are Peter A. Fasullo, Donald R. Kendall Jr. and Gerald A. Tywoniuk. Mssrs. Fasullo, Kendall and Tywoniuk serve as the
members of the Audit Committee, with Mr. Tywoniuk serving as chairman. Our General Partner

96

is generally required to have at least three independent directors serving on its board at all times. The Board has determined that Mr. Tywoniuk is a financial expert
as defined by the NYSE and the Exchange Act.

Directors are appointed for a term of one year and hold office until their successors have been elected or qualified or until the earlier of their death, resignation,
removal or disqualification. Executive officers serve at the discretion of the Board and are subject to the terms of their employment agreements, if applicable. The
following table shows information for the executive officers and directors of our General Partner as of March 1, 2018:

Our compensation program is designed to recognize key managers are critical to our Partnership's profitability and growth. We utilize compensation to attract and
retain  management  talent  and  to  motivate  key  employees  to  focus  consistently  on  growth  and  value  creation.  In  addition,  our  compensation  program  aligns
incentives for management and unitholders, focusing on long-term value creation rather than short-term gain.

This  section  should  be  read  together  with  the  compensation  tables  that  follow,  which  disclose  the  compensation  awarded  to,  earned  by,  or  paid  to,  the  named
executive officers with respect to the three years ended December 31, 2017 .

Role of the Board, the Compensation Committee and Management

The Board has appointed the Compensation Committee to assist the Board in discharging its responsibilities relating to compensation matters, including matters
relating  to  compensation  programs  for  directors  and  executive  officers  of  the  General  Partner.  The  Compensation  Committee  has  overall  responsibility  for
evaluating and approving our compensation plans, policies and programs, setting the compensation and benefits of executive officers, and granting awards under
and  administering  our  equity  compensation  plans.  The  Compensation  Committee  is  charged  with,  among  other  things,  establishing  compensation  practices  and
programs that are i) designed to attract, retain and motivate exceptional leaders, ii) structured to align compensation with our

101

          
overall  performance  and  growth  in  distributions  to  unitholders,  iii)  implemented  to  promote  achievement  of  short-term  and  long-term  business  objectives
consistent with our strategic plans, and iv) applied to reward performance.

As described in further detail below under " — Elements of the Compensation Programs, " the compensation programs for our executive officers consist of base
salaries, annual incentive bonuses and awards under the American Midstream GP, LLC, Long-Term Incentive Plan, which we refer to as our LTIP, currently in the
form of equity-based phantom units, as well as other customary employment benefits such as a 401(k) plan, and health and welfare benefits. We expect that total
compensation of our executive officers and the components of compensation and allocation among components of their annual compensation will be reviewed on
at least an annual basis by the Compensation Committee. Management, on behalf of the compensation committee, engaged the services of Mercer, a compensation
consultant, to conduct a study to assist us in establishing overall compensation packages for the executive officers for 2017. We consider Mercer to be independent
of the Partnership and therefore, the work performed by Mercer does not create a conflict of interest. The Mercer study was based on compensation for a group of
peer companies with similar operations obtained from public documents as well as multiple survey sources, including the 2016 Mercer Benchmark Database and
the 2016 Mercer Total Compensation Survey for the Energy Sector.

During 2017 ,  the  Compensation  Committee  discussed  executive  compensation  issues  at  several  meetings,  and  the  Compensation  Committee  expects  to  hold
additional executive compensation-related meetings in 2018 and in future years. Topics discussed and to be discussed at these meetings included and will include,
among  other  things,  i)  assessing  the  performance  of  the  Chief  Executive  Officer,  with  respect  to  our  results  for  the  prior  year,  ii)  reviewing  and  assessing  the
personal performance of the executive officers and other key managers for the preceding year and iii) determining the amount of the bonus pool to be paid to our
executives and other key managers for a given year after taking into account the target bonus amounts established for those executives and other key managers at
the  outset  of  the  year.  In  addition,  at  these  meetings,  and  after  taking  into  account  the  recommendations  of  our  Chief  Executive  Officer  only  with  respect  to
executive  officers  and  key  managers  other  than  our  Chief  Executive  Officer,  base  salary  levels  and  target  bonus  amounts  (representing  the  bonus  that  may  be
awarded expressed as a dollar amount or as a percentage of base salary for the year) for our executive officers was (and will continue to be) established by the
Compensation Committee. In addition, the Compensation Committee made (and will continue to make) its decisions with respect to any awards under the LTIP
and recommend awards to the Board. Our Chief Executive Officer provides periodic recommendations to the Compensation Committee regarding the performance
and compensation of the other named executive officers as well as the amounts allocated to the short-term incentive plan and LTIP compensation pools.

Compensation Objectives and Methodology

The principal objective of our executive compensation program is to attract and retain individuals of demonstrated competence, experience and leadership who
share our business aspirations, values, ethics and culture. A further objective is to provide incentives to and reward our executive officers and other key employees
for positive contributions to our business and operations, and to align their interests with our unitholders' interests.

In setting our compensation programs, we consider the following objectives:

•
•
•
•
•

to create unitholder value through sustainable earnings and cash available for distribution;
to provide a significant percentage of total compensation that is "at-risk" or variable;
to encourage significant equity holdings to align the interests of executive officers and other key employees with those of unitholders;
to provide competitive, performance-based compensation programs that allow us to attract and retain superior talent; and
to develop a strong linkage between business performance, safety, environmental stewardship, cooperation and executive compensation.

Taking account of the foregoing objectives, we structure total compensation for our executives to provide a guaranteed amount of cash compensation in the form of
base salaries, while also providing a meaningful amount of annual cash compensation that is at risk and dependent on our performance and individual performance
of the executives, in the form of discretionary annual bonuses. We also seek to provide a portion of total compensation in the form of equity-based awards under
our LTIP, in order to align the interests of executives and other key employees with those of our unitholders and for retention purposes.

Compensation decisions for individual executive officers are the result of the subjective analysis of a number of factors, including the individual executive officer's
experience,  skills  or  tenure  with  us  and  changes  to  the  individual  executive  officer's  position.  In  evaluating  the  contributions  of  executive  officers  and  our
performance, although no pre-determined numerical goals were established, a variety of financial measures have been generally considered, including non-GAAP
financial measures used by management to assess our financial performance, such as Adjusted EBITDA and distributable cash flow. For a definition of Adjusted
EBITDA and a reconciliation to its most directly comparable financial measure calculated and presented in accordance with GAAP

102

and a discussion of how we use Adjusted EBITDA to evaluate our operating performance, see "Management's Discussion and Analysis —How We Evaluate Our
Operations ". In addition, a variety of factors related to the individual performance of the executive officer were taken into consideration.

In making individual compensation decisions, the Compensation Committee historically has not relied on pre-determined  performance goals or targets. Instead,
determinations  regarding  compensation  have  resulted  from  the  exercise  of  judgment  based  on  all  reasonably  available  information  and,  to  that  extent,  were
discretionary.  The  amount  of  each  executive  officer's  current  compensation  will  be  considered  as  a  base  against  which  determinations  are  made  as  to  whether
increases are appropriate to retain the executive officer in light of competition or in order to provide continuing performance incentives. Subject to the provisions
contained in the executive officer's employment agreement, if any, the Compensation Committee has discretion to adjust any of the components of compensation
to  achieve  our  goal  of  recruiting,  promoting  and  retaining  executive  officers  and  key  individuals  with  the  skills  necessary  to  execute  our  business  strategy  and
develop, grow and manage our business.

The Compensation Committee has also utilized benchmarking compensation levels across a range of publicly traded Master Limited Partnerships operating in the
midstream market to inform specific award levels for named executive officers and key managers. Going forward, we expect that the Compensation Committee
will  make  compensation  decisions  taking  into  account  trends  occurring  within  our  industry,  including  from  a  peer  group  of  companies,  which  we  expect  will
include, but not be limited to, the following similar publicly traded partnerships: Buckeye Partners LP, Crestwood Equity Partners LP, DCP Midstream,Partners
LP,  Enable  Midstream  Partners  LP,  Enlink  Midstream  Partners  LP,  Genesis  Energy  LP,  Magellan  Midstream  Partners  LP,  Nustar  Energy  LP,  SemGroup
Corporation, Southcross Energy Partners LP, Summit Midstream Partners LP and Targa Resources Corp.

Elements of the Compensation Programs

Overall, the executive officer compensation programs are designed to be consistent with the philosophy and objectives set forth above. The principal elements of
our executive officer compensation programs are summarized in the table below, followed by a more detailed discussion of each compensation element.

  Base Salaries

Base salaries for our executive officers will be determined annually by an assessment of our overall financial and operating performance, each executive officer's
performance  evaluation  and  changes  in  executive  officer  responsibilities.  While  many  aspects  of  performance  can  be  measured  in  financial  terms,  senior
management will also be evaluated in areas of performance that are more subjective. These areas include development and execution of strategic plans, leading the
development  of  management  and  other  employees,  innovation  and  improvement  in  our  business  activities  and  each  executive  officer's  involvement  in  industry
groups and in the communities that we serve. We seek to compensate executive officers for their performance throughout the year with annual base salaries that are
fair and competitive within our marketplace. We believe that executive officer base salaries should be competitive with salaries for executive officers in similar
positions  and  with  similar  responsibilities  in  our  marketplace  and  adjusted  for  financial  and  operating  performance  and  each  executive  officer's  performance
evaluation, length of service with us and previous work experience. Individual salaries have historically been established by the Board, upon the recommendation
of the Compensation Committee, based on the general industry knowledge and experience of its members, in alignment with these considerations, to ensure the
attraction, development and retention of superior talent. Going forward, we expect that salary decisions will continue to focus on the above considerations and will
also take into account relevant market data, including the market data and peer group data.

We  expect  that  base  salaries  will  be  reviewed  annually  to  ensure  continuing  consistency  with  market  levels  and  our  level  of  financial  performance  during  the
previous year. Future adjustments to base salaries and salary ranges will reflect movement in the competitive market as well as individual performance. Annual
base  salary  adjustments,  if  any,  for  the  Chief  Executive  Officer  will  be  determined  by  the  Board  upon  the  recommendation  of  the  Compensation  Committee.
Annual  base  salary  adjustments,  if  any,  for  the  other  executive  officers  will  be  determined  by  the  Board  upon  the  recommendation  of  the  Compensation
Committee, taking into account input from the Chief Executive Officer.

The Compensation Committee approved the following base salaries for 2017 for the named executive officers as provided in the table below.

As one way of accomplishing our compensation objectives, executive officers are rewarded for their contribution to our financial and operational success through
the award of discretionary annual cash incentive bonuses. Annual cash incentive awards, if any, for the Chief Executive Officer are determined by the Board upon
the recommendation of the Compensation Committee. Annual cash incentive awards, if any, for the other executive officers are determined by the Board upon the
recommendation of the Compensation Committee taking into account input from the Chief Executive Officer.

We review cash bonus awards for the named executive officers annually to determine award payments for the prior fiscal year, as well as to establish target bonus
amounts for the current fiscal year. At the beginning of each year, the Compensation Committee meets with the Chief Executive Officer to discuss Partnership and
individual goals for the year and what each executive is expected to contribute in order to help the Partnership achieve those goals. However, the amounts of the
annual bonuses have been and are determined at the discretion of the Board upon the recommendation of the Compensation Committee with input from the Chief
Executive Officer.

While target bonuses for our executive officers have been initially set at dollar amounts that are between 75% to 100% of their base salaries, the Compensation
Committee  has  had  broad  discretion  to  retain,  reduce  or  increase  the  award  amounts  when  making  its  final  bonus  recommendations.  Bonuses  (similar  to  other
elements of the compensation provided to executive officers) historically have not been solely based on a prescribed formula or pre-determined goals, specified
performance targets but rather have been determined on a discretionary basis and generally have been based on a subjective evaluation of individual, company-
wide  and  industry  performances.  Target  bonus  amounts  for  2017  for  all  of  the  executive  officers  are  set  forth  in  the  table  below.  Target  bonus  amounts  were
changed to align with our new strategy to ensure that each level of executive management was operating with the same targets.

104

 
 
 
 
 
 
The Board and the Compensation Committee believe that this approach to assessing performance results in a more comprehensive evaluation for compensation
decisions. In 2017, the Compensation Committee recognized the following factors in making discretionary annual bonus recommendations and determinations:

•

•
•

a subjective company performance evaluation based on company-wide financial performance including actual EBITDA versus budgeted EBITDA to assess
company performance and adjusted as needed for new acquisitions and major capital expenditure programs in 2017;
a subjective individual performance evaluation for executive officers and other factors deemed relevant; and
the scope, level of expertise and experience required for the executive officer's position.

These factors were selected as the most appropriate measures upon which to base the annual incentive cash bonus decisions because our Compensation Committee
believes that they help to align individual compensation with performance and contribution. With respect to its evaluation of company-wide financial performance,
although no pre-determined numerical goals were established, the Compensation Committee generally reviewed our results with respect to Adjusted EBITDA as
compared to operating budget and cash available for distribution in making annual bonus determinations.

Following  its  performance  assessment,  and  based  on  our  financial  performance  with  respect  to  these  criteria  and  the  Compensation  Committee's  qualitative
assessment of individual performance, the Board upon the recommendation of the Compensation Committee, determined to award the incentive bonus amounts,
which were paid in cash, set forth in the table below to our named executive officers for performance in 2017.

For 2017, the Compensation Committee determined base annual incentive compensation award recommendations on additional company-wide criteria as well as
industry criteria, recognizing the following factors as part of its determination of annual incentive bonuses (without assigning any particular weight to any factor):

•
•
•
•

financial performance for the prior fiscal year, including Adjusted EBITDA and distributable cash flow;
distribution performance for the prior fiscal year;
unitholder total return for the prior fiscal year; and
competitive compensation data of executive officers.

These  factors  were  selected  as  the  most  appropriate  measures  upon  which  to  base  the  annual  cash  incentive  bonus  decisions  going  forward  because  the
Compensation Committee believes that they will most directly correlate to increases in long-term value for our unitholders.

Equity-Based Awards

Design.  The LTIP was adopted in November 2009 in connection with our formation and was most recently amended and restated in 2016. In adopting the LTIP,
the Board recognized that it needed a source of equity to attract new members to and retain members of the management team, as well as to provide an equity
incentive  to other  key employees  and non-employee  directors.  We believe  the LTIP promotes  a long-term  focus on results  and aligns  executive  and unitholder
interests.

The LTIP is designed to encourage responsible and profitable growth while taking into account non-routine factors that may be integral to our success. Long-term
incentive compensation in the form of equity grants are used to provide incentives for performance that leads to enhanced unitholder value, encourage retention
and  closely  align  the  executive  officers'  interests  with  unitholders'  interests.  Equity  grants  provide  a  vital  link  between  the  long-term  results  achieved  for  our
unitholders and the rewards provided to executive officers and other key employees.

Phantom Units. A phantom unit is a notional unit granted under the LTIP that entitles the holder to receive an amount of cash equal to the fair market value of one
Common Unit upon vesting of the phantom unit, unless the Board elects to pay such vested

105

 
 
 
 
 
 
phantom unit with a common unit in lieu of cash. Unless an individual award agreement provides otherwise, the LTIP provides that unvested phantom units are
forfeited at the time the holder terminates employment or Board membership, as applicable. The terms of the award agreements of our named executive officers
provide that a termination due to death or long-term disability results in full acceleration of vesting. In general, phantom units awarded under our LTIP vest as to
25% of the award on each of the first four anniversaries of the date of grant.

Unit Options. A unit option is a right to purchase a Common Unit at the fair market value per Common Unit on the date of grant. The Compensation Committee
has utilized unit option grants in special circumstances associated with the new hire or promotion of a named executive officer, and each award has unique vesting
terms.

Performance  Based Awards.  In  November  2017,  the  Board  of  Directors  of  our  General  Partner  approved  the  grant  of  performance  based  awards  ("PSUs")  to
create a highly accretive, long-term retention tool to key personnel whom management expects to drive performance over the long-term. The awards will vest on
November 20, 2022, subject to acceleration in certain circumstances.

Equity-Based Award Policies. The LTIP is administered by the Compensation Committee of the Board. The Compensation Committee, at its discretion, may elect
to settle each vested phantom units with a Common Unit at the date of vesting in lieu of cash.

Generally,  grants  issued  under  the  LTIP  vest  in  increments  of  25%  on  each  grant  anniversary  date  and  do  not  contain  any  vesting  requirements  other  than
continued employment. Ownership in the awards is subject to forfeiture until the vesting date.

Deferred Compensation. Tax-qualified retirement plans are a common way that companies assist employees in preparing for retirement. We provide our eligible
executive officers and other employees with an opportunity to save for their retirement by participating in our 401(k) plan. The 401(k) plan allows our executive
officers and other employees to defer compensation (up to IRS imposed limits) for retirement and permits us to make annual discretionary matching contributions
to  the  plan.  For  2017,  we  matched  employee  contributions  to  401(k)  plan  accounts  up  to  a  maximum  employer  contribution  of  6%  of  the  employee's  eligible
compensation. Decisions regarding this element of compensation do not impact any other element of compensation.

Other Benefits. Each of the named executive officers is eligible to participate in our employee benefit plans which provide for medical, dental, vision, disability
insurance and life insurance benefits, which are provided on the same terms as available generally to all salaried employees.

Recoupment  Policy.  We  currently  do  not  have  a  recoupment  policy  applicable  to  annual  incentive  bonuses  or  equity  awards.  The  Compensation  Committee
expects to continue to evaluate the need to adopt such a policy in 2018, in light of current legislative policies as well as economic and market conditions.

Employment, Change in Control and Severance Arrangements. The Board and the Compensation Committee consider the maintenance of a sound management
team to be essential to protecting and enhancing our best interests. To that end, we recognize that the uncertainty that may exist among management with respect to
their "at-will" employment with our General Partner may result in the departure or distraction of management personnel to our detriment. Accordingly, our General
Partner has agreed to severance arrangements for Mr. Bourdon that we believed were appropriate to encourage the continued attention and dedication of members
of our management. These severance arrangements are described more fully below under "—  Employment Agreements with Named Executive Officers."

Amounts shown in this column do not reflect dollar amounts actually received by each of our named executive officers. Instead, these amounts reflect the
aggregate  grant  date  value  of  each  phantom  unit  award,  unit  options  award  granted,  and  the  performance  unit  awards  in  each  of  the  three  years  ended
December 31, 2017. In general, employees are not entitled to distributions declared on the underlying unit while the phantom unit is unvested; therefore, the
grant date fair value of the phantom units is calculated by reducing the grant date price, by the present value of the distributions expected to be paid on the
underlying  units  during  the  requisite  service  period.  See  the  table  below  for  these  calculations.  For  additional  information  on  the  assumptions  used  to
calculate the grant date fair value of equity incentive awards, refer to Note 18 - Long-Term Incentive Plan  of this Annual Report, incorporated herein by

In April 2017, the Board of Directors of our General Partner approved the grant of an option to purchase 15,000 common units of the Partnership at an
exercise price per unit equal to $14.85. The options will vest over four years at a rate of 25% per year. The options expire on April 3, 2027, or ten years
from the date of grant.

Employment Agreements with Named Executive Officers ("NEO")

Our General Partner has entered into an employment agreement with Lynn L. Bourdon III. The employment agreement with Mr. Bourdon has an initial term of
three years, which will be automatically extended for successive one-year terms until either party elects to terminate the agreement by providing written notice at
least 60 days prior to the end of the expiration of the initial or extended term, as applicable. The base salary and target bonus amounts set forth in Mr. Bourdon’s
employment  agreement  is  shown  in  the  table  below  and  the  employment  agreement  provides  that  the  base  salary  may  be  increased  but  not  decreased.  Mr.
Bourdon’s  employment  agreement  provides  that  he  will  be  provided  with  the  opportunity  to  earn  an  annual  cash  bonus,  a  certain  percentage  of  which  will  be
conditioned and determined on the attainment of personal performance goals and the balance of which will be conditioned and determined on the attainment of
organizational  performance  goals,  in  each  case  as  set  by,  and  based  on  performance  criteria  established  by,  the  Compensation  Committee.  Mr.  Bourdon’s
employment agreement also provides that the executive may also be eligible to receive awards under the LTIP as determined by the Compensation Committee.

Mr.  Bourdon’s  employment  agreement  also  contains  certain  confidentiality  covenants  prohibiting  him  from,  among  other  things,  disclosing  confidential
information relating to our General Partner or any of its affiliates, including us. The employment agreement also contains non-competition  and non-solicitation
restrictions,  which  apply  during  the  term  of  Mr.  Bourdon’s  employment  with  our  General  Partner  and,  with  certain  exceptions,  continue  for  a  period  of  6-
12 months following termination for any reason.

The market value of phantom units that had not vested as of December 31, 2017 was calculated based on the fair market value of our Common Units as of
December 31, 2017, which was $13.35 multiplied by the number of unvested phantom units. See   Management's Discussion and Analysis of Financial
Condition and Results of Operations  - Critical Accounting Policies and Estimates Equity-Based Awards  in Part II, Item 7 of this Annual Report.

In conjunction with the execution of Mr. Bourdon’s employment agreement effective December 10, 2015, the Board approved a grant of 200,000 phantom
units  of  the  Partnership.  The  phantom  units  contain  DERs  based  on  the  extent  to  which  the  Partnership's  Series  A  Preferred  Unitholders  receive
distributions in cash. The grant will vest on January 1, 2019, subject to acceleration in certain circumstances and will expire on March 15th of the calendar
year following the calendar year in which it vests. 

Effective  August  2016,  the  Board  approved  the  grant  of  an  option  to  purchase  30,000  common  units.  The  grant  will  vest  on  July  31,  2019,  subject  to
continued employment, and will expire on July 31st of the calendar year following the calendar year in which it vests.

In April 2017, the Board of Directors of our General Partner approved the grant of an option to purchase 15,000 common units of the Partnership at an
exercise price per unit equal to $14.85. The options will vest over four years at a rate of 25% per year. The options expire on April 3, 2027, or ten years
from the date of grant.

The market  value of performance  units was calculated  based on the grant date fair value of our performance  units which was $12.13 multiplied  by the
number of unvested performance units. A Monte-Carlo pricing model was used to determine the fair value of our performance grants. In November 2017,
the Board of Directors of our General Partner approved the grant of performance based awards to create a highly accretive, long-term retention tool to key
personnel  whom management  expects to drive performance  over the long-term. The awards will vest on November 20, 2022, subject to acceleration  in
certain circumstances. See   Management's Discussion and Analysis of Financial Condition and Results of Operations  - Critical Accounting Policies and
Estimates Equity-Based Awards  and Note 18 - Incentive Compensation  in Part II, Item 8 in this Annual Report for additional information.

(6)   Ownership  in  the  phantom  unit  awards  is  subject  to  forfeiture  until  the  vesting  date.  The  LTIP  is  administered  by  the  Compensation  Committee  of  the
Board  of  Directors  of  our  General  Partner,  which  at  its  discretion,  may  elect  to  settle  such  vested  phantom  units  with  common  units  in  lieu  of  cash.
Although our General Partner has the option to settle vested phantom units in cash, our General Partner has not historically settled these awards in cash.
Under the LTIP, phantom units typically vest in increments of 25% on each grant anniversary date and do not contain any vesting requirements other than
continued employment.

Potential Payments Upon Termination or Change in Control

Employment Agreement with Lynn L. Bourdon III

The  employment  agreement  with  Lynn  L.  Bourdon  III  provides  for,  among  other  things,  the  payment  of  severance  benefits  following  certain  terminations  of
employment by our General Partner or the termination of employment by Mr. Bourdon for “Good Reason” (as defined below). If Mr. Bourdon’s employment is
terminated by our General Partner other than for “Cause” (as defined below) or other than on Mr. Bourdon’s death or disability, or if Mr. Bourdon terminates his
employment for Good Reason, Mr. Bourdon will receive a cash amount equal to his annual base salary in effect on the date of terminations plus the amount of his
current year annual cash bonus for the year of termination at the target calculated as if all goals for a target bonus have been achieved. In these circumstances, Mr.
Bourdon  would  also  receive  certain  medical  premium  reimbursements  and  either  accelerated  or  continued  vesting  of  certain  equity  incentive  awards.  The
severance benefits contained in his employment agreement are conditioned on Mr. Bourdon executing a release of claims in favor of our General Partner and its
affiliates, including the Partnership. In the event that such a termination of his employment occurs within two years after a change in control, Mr. Bourdon may be
entitled  to  receive  two  times  the  severance  amount.  The  employment  agreement  provides  for  accelerated  vesting  of  certain  equity  incentive  awards  upon  Mr.
Bourdon's death or disability.

•

“Cause” means Mr. Bourdon has (i) engaged in gross negligence in the performance of the duties required of him; (ii) engaged in willful misconduct in the
performance  of  the  duties  required  of  him  resulting  in  a  material  detriment  to  our  General  Partner;  (iii)  unlawfully  used  (including  being  under  the
influence of) or possessed illegal drugs on our General Partner’s (or any of its affiliate’s) premises or while performing his duties or responsibilities; (iv)
committed a material act of fraud or embezzlement against our General Partner, its affiliates, or any of their respective equity holders; (v) been convicted
of (or pleaded  guilty or no contest  to) a felony, other than a non-injury vehicular  offense, that could be reasonably  expected  to reflect  unfavorably  and
materially on our General Partner; or (vi) materially breached or violated any material provision of the agreement or violated any material provision of any
material written company policy that has been previously provided or made available to Executive.

•

“Good Reason” means, in connection with or based upon a nonconsensual (i) material alteration in Mr. Bourdon's responsibilities, duties, authority or titles
or the assignment to Mr. Bourdon of duties or responsibilities inconsistent with Mr. Bourdon's status and titles as the most senior officer of our General
Partner; (ii) assignment of Mr. Bourdon to a principal office located beyond a 30-mile radius of Mr. Bourdon's then current work place; or (iii) material
breach by any party to the agreement other than Executive of any material provision of the agreement.

The employment agreement provides that for a period of twelve months following a termination of employment by Mr. Bourdon for Good Reason (or nine months
following a termination of employment of Mr. Bourdon by our General Partner or Mr. Bourdon due to the Company’s non-renewal of the employment agreement
or a termination of employment by the Company without Cause), Mr. Bourdon will be subject to a non-competition covenant. Furthermore, if our General Partner
elects to pay Mr. Bourdon a cash amount equal to half of the severance amount following a termination of Mr. Bourdon’s employment by our General Partner for
Cause or by Mr. Bourdon without Good Reason, then Mr. Bourdon will be subject to a six month non-competition covenant. Mr. Bourdon is also subject to a non-
solicitation covenant for a period of twelve months following the termination of his employment.

Mr. Bourdon has received an award of phantom units under the LTIP. The terms of the phantom unit award agreement provide that a termination without Cause,
for Good Reason, or due to death or disability, results in full acceleration of vesting of any outstanding phantom units.

Severance Agreement with Eric T. Kalamaras

Mr. Kalamaras’ offer letter for his employment as our Chief Financial Officer provides for the payment of severance benefits following certain terminations of
employment by our General Partner. Under the terms of the offer letter, the severance arrangement terminated by its terms on July 11, 2017.

The following table shows the value of the severance benefits and other benefits for the named executive officers under the employment agreements and phantom

(1)   The  amounts  shown in this  row are  calculated  based  on the  fair  market  value  of  our  Common Units  which  we have  assumed  were  $13.35, which  was the
closing price of our Common Units on December 31, 2017, multiplied by the number of phantom units that would have vested as of December 31, 2017. The
market value of the Option Grant that has not vested as of December 31, 2017 for Mr. Bourdon is $5.85, per Common Unit subject to the option, which is the
difference between the closing price of our Common Units on December 31, 2017 and the exercise price.

(2)   In connection with a termination of the executive's employment upon expiration of the initial or extended term of the agreement by either party pursuant to the
terms  of  the  employment  agreement,  the  Board  may,  in  its  discretion,  release  the  executive  from  being  subject  to  the  non-competition  covenant  following
termination of employment; however, in such case, the executive would not be entitled to receive the severance payment.

(3)   Pursuant to the employment agreement, accelerated vesting of all unvested long-term equity incentive awards under the LTIP would only occur under certain

types of change of control transactions.

(4)   In the event that Mr. Bourdon is terminated without cause or resigns for Good Reason within two years after a change in control, Mr. Bourdon may be entitled

to receive two times the severance amount or $2,000,000.

Pay Ratio

As required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, and Item 402(u) of Regulation S-K, the following disclosure
provides the ratio of the annual total compensation of Mr. Bourdon, our President and Chief Executive Officer, to the annual total compensation of the median
employee of our general partner. All of our general partner's employees (including executive officers) are dedicated exclusively to the Partnership and our general
partner determines the compensation of our Chief Executive Officer and employees.

For 2017, Mr. Bourdon's annual total compensation was $2,121,203, as reported in the Total column of the 2017 Summary Compensation Table included in this
Item  11,  and  the  annual  total  compensation  of  the  median  compensated  employee  was  $77,301.  Based  on  this  information,  the  ratio  of  the  annual  total
compensation of Mr. Bourdon to the median compensated employee for 2017 was to 27:1.

The pay ratio reported above is a reasonable estimate calculated in a manner consistent with the SEC rules based on our payroll and employment records and the
methodology  described  below.  For  these  purposes,  using  our  employee  population  and  payroll  register  as  of  December  31,  2017,  we  identified  the  median
compensated employee by annualizing base salary earned in December 2017 for all employees. To this we added, for all employees, target cash bonus and the
estimated 401(k) employer matching for the 2017 performance year.

The  SEC’s  rules  for  identifying  the  median  compensated  employee  and  calculating  the  pay  ratio  based  on  that  employee’s  annual  total  compensation  allow
companies  to  adopt  a  variety  of  methodologies,  to  apply  certain  exclusions,  and  to  make  reasonable  estimates  and  assumptions  that  reflect  their  employee
populations and compensation practices. As a result, the pay ratio reported by other companies may not be comparable to the pay ratio reported above, as other
companies  have  different  employee  populations  and  compensation  practices  and  may  utilize  different  methodologies,  exclusions,  estimates  and  assumptions  in
calculating their own pay ratios.

Compensation Committee Interlocks and Insider Participation

The  Compensation  Committee  of  the  Board  was  comprised  of  Messrs.  Bourdon  and  Erhard  as  of  December  31,  2017.  The  Compensation  Committee  makes
compensation recommendations to the full Board regarding the executive officers of our General Partner. With the exception of Mr. Bourdon, none of the members
of the Compensation Committee is or has been one of our officers or employees, and none of our executive officers served during 2017 on a board of directors or
compensation committee of another entity which has employed any of the members of our Board or Compensation Committee.

Compensation of Directors

Director Fees

During 2017, each director who was not an officer or employee of our General Partner received compensation for attending meetings of the Board of Directors, as
well as committee meetings, as follows:

114

•
•
•
•

a $50,000 annual cash retainer;
a $50,000 annual unit grant;
where applicable, a variable fee for service rendered as member of the Conflicts Committee to the Board; and
where applicable, a committee chair retainer of $10,000 for each committee chaired.

In addition, each non-employee director received per meeting fees of:

•
•
•

$1,000 for meetings attended in person;
where applicable, $500 for committee meetings attended in person; and
$500 for telephonic meetings and committee meetings greater than one hour in length.

The  Compensation  Committee  of  the  Board,  following  a  review  of  the  compensation  of  our  Board  of  Directors,  recommended  to  the  Board,  and  the  Board
approved, the following compensation for each director who is not an officer or employee of our General Partner beginning on January 1, 2018. The compensation
was determined by conducting an analysis of compensation paid to non-employee directors by our peer group.

•
•
•
•
•

a $70,000 annual cash retainer;
a $70,000 annual unit grant;
a $15,000 retainer paid to the chairman of the Audit Committee;
a $2,500 cash payment, per transaction, for service rendered as a member of the Conflicts Committee to the Board; and
a $5,000 cash payment, per transaction, for service rendered as the Chairman of the Conflicts Committee to the Board.

Effective June 1, 2017, Mr. Bergstrom was appointed as the Executive Strategy Advisor to our General Partner. As a result of Mr. Bergstrom’s employment by the
General Partner, he is not eligible to receive compensation as a board member. Instead, Mr. Bergstrom’s compensation for his role as Executive Strategy Advisor is
at the same level as if he were a non-employee member of the Board. Thus, for 2018, Mr. Bergstrom will be paid an annual salary of $70,000 and will be eligible
for  an  annual  unit  grant  of  $70,000.  As  a  result  of  his  employment  with  the  General  Partner,  Mr.  Bergstrom  is  eligible  to  participate  in  the  General  Partner’s
medical, dental, vision, flexible spending accounts, 401(k) retirement plan and the other benefit programs offered to all employees.

Generally,  directors  listed  in  the  table  below  are  reimbursed  for  out-of-pocket  expenses  in  connection  with  attending  meetings  of  the  Board  of  Directors  or  its
committees.  Each  director  will  be  fully  indemnified  by  us  for  actions  associated  with  being  a  director  of  our  General  Partner  to  the  extent  permitted  under
Delaware law.

Director Compensation Table for 2017

The following table sets forth the compensation paid to our non-employee directors for the year ended December 31, 2017 , as described above. The compensation
paid  in  2017  to  Mr.  Bourdon  as  an  executive  officer  is  set  forth  in  the  summary  compensation  tables  above.  Mr.  Bourdon  did  not  receive  any  additional
compensation related to his service as a director.

Compensation Committee Report

During 2017 , the Compensation Committee of the Board was comprised of two directors (Messrs. Bourdon and Erhard).

The Compensation Committee has discussed and reviewed the above Compensation Discussion and Analysis for fiscal year 2017 with management. Based on this
review  and  discussion,  the  Compensation  Committee  recommended  to  the  Board  that  this  Compensation  Discussion  and  Analysis  be  included  in  this  Annual
Report on Form 10-K for the fiscal year 2017 .

Compensation Practices as They Relate to Risk Management

We  do not believe  that  our compensation  policies  and practices  create  risks that are  reasonably  likely  to have a material  adverse  effect  on the Partnership.  We
believe  our  compensation  programs  do  not  encourage  excessive  and  unnecessary  risk  taking  by  executive  officers  (or  other  employees).  Short-term  annual
incentives are generally paid pursuant to discretionary bonuses enabling the CEO and Compensation Committee to assess the actual behavior of our employees as
it relates to risk taking in awarding a bonus. Our use of equity based long-term compensation serves our compensation program's goal of aligning the interests of
executives and unitholders, thereby reducing the incentives to unnecessary risk taking.

Item 12. Security Ownership of Certain Beneficial Owners and Management and Related Unitholder Matters

The following table sets forth certain information regarding the beneficial ownership of units as of March 26, 2018 and the related transactions by:

•
•
•
•

each person who is known to us to beneficially own 5% or more of such units to be outstanding;
our General Partner;
each of the directors and named executive officers of our General Partner; and
all of the directors and executive officers of our General Partner as a group.

All information with respect to beneficial ownership has been furnished by the respective directors, officers or 5% or more unitholders as the case may be.

As of December 31, 2017, our General Partner is owned 77% directly by HPIP and 23% indirectly by Magnolia Infrastructure Holding, LLC, both controlled by
ArcLight.

The amounts and percentage of units beneficially owned are reported on the basis of regulations of the SEC governing the determination of beneficial ownership of
securities. Under the rules of the SEC, a person is deemed to be a "beneficial owner" of a security if that person has or shares "voting power," which includes the
power to vote or to direct the voting of such security, or "investment power," which includes the power to dispose of or to direct the disposition of such security. In
computing the number of common units beneficially owned by a person and the percentage ownership of that person, common units subject to options or warrants
held by that person that are currently exercisable or exercisable within 60 days of March 26, 2018, if any, are deemed outstanding, but are not deemed outstanding
for  computing  the  percentage  ownership  of  any  other  person.  Except  as  indicated  by  footnote,  the  persons  named  in  the  table  below  have  sole  voting  and
investment power with respect to all units shown as beneficially owned by them, subject to community property laws where applicable.

Distributions and Payments to our General Partner and its Affiliates

The following summarizes the distributions and payments to be made by us to our General Partner and its affiliates  in connection with our formation, ongoing
operation and any liquidation of the Partnership. These distributions and payments were determined by and among affiliated entities and, consequently, are not the
result of arm's-length negotiations.

Distributions of available cash to our General Partner and its affiliates:

HPIP, as the holder of 7,707,571 Series A-1 Units, MIP (an affiliate of HPIP), as the holder of 3,302,158 Series A-2 Units, and Magnolia Infrastructure Holdings,
LLC (an affiliate of HPIP), as the holder of 9,241,642 Series C Units, are entitled to receive cumulative distributions consisting of cash and Series A and C PIK
preferred  units, respectively,  prior to any other distributions  made in respect  of any other partnership  interests  (the "Series A and C Quarterly  Distribution")  in
accordance with our Partnership Agreement. With respect to the coupon conversion quarter (as defined in our Partnership Agreement) and all quarters thereafter,
the  Series  A  Quarterly  Distribution  shall  be  paid  entirely  in  cash  in  accordance  with  our  Partnership  Agreement.  To  the  extent  that  any  portion  of  a  Series  A
Quarterly Distribution to be paid in cash with respect to any quarter exceeds the amount of available cash for such quarter, an amount of cash equal to the available
cash for such quarter will be paid to the Series A and C unitholders and the balance of such Series A and C Quarterly Distribution shall be unpaid, constitute an
arrearage and accrue interest.

With respect to the quarter ended June 30, 2016 and for each Quarter thereafter through and including the quarter ended December 31, 2018, in the discretion of
the General Partner and upon the consent of Magnolia, the Series C Quarterly Distribution may be paid partially or entirely in a number of Series C PIK preferred
units. With respect to the Quarter ending March 31, 2019 and all quarters thereafter, the Series C Quarterly Distributions will be paid entirely in cash.

After making the Series A and C convertible preferred quarterly distribution and paying any arrearage and accrued interest with respect to the Series A Units, we
will distribute available cash from operating surplus for any quarter 98.7% to our common unitholders, and 1.3% to our General Partner in respect of its general
partnership interest, assuming it makes any capital contributions necessary to maintain its 1.3% General Partner interest in us. In addition, if distributions exceed
the minimum quarterly distribution and target distribution levels, the holders of our incentive distribution rights will be entitled to increasing percentages of the
distributions, up to 48.0% of the distributions above the highest target distribution level.

Magnolia Infrastructure Holdings, LLC (an affiliate of HPIP), as the holder of 2,333,333 Series D Units was entitled to receive cumulative distributions consisting
of cash, in the same priority as the Series A Units and the Series C Units and prior to any other distributions made in respect of any other partnership interests (the
“Series D Quarterly Distribution”) in accordance with our Partnership Agreement. On October 2, 2017, pursuant to the terms of our Partnership Agreement, we
exercised our call right to repurchase all of the 2,333,333 outstanding Series D Units from Magnolia Infrastructure Holdings, LLC, an affiliate of ArcLight, for
approximately $34.5 million in cash, which was funded through our existing revolver. After the closing date of such redemption, which occurred on October 2,
2017, there were no more outstanding Series D Units.

Payments to our General Partner and its affiliates

Our General Partner will not receive a management fee or other compensation for its management of us. However, we will reimburse our General Partner and its
affiliates for all expenses incurred on our behalf. Our Partnership Agreement provides that our General

119

Partner will determine the amount of these reimbursed expenses. For further information about the relationship between the General Partner and the Partnership,
see Note 21. Related Party Transactions - General Partner in Part II, Item 8 in this Annual Report.

Withdrawal or removal of our General Partner

If our General Partner withdraws or is removed, its General Partner interest and its incentive distribution rights will either be sold to the new General Partner for
cash or converted into common units, in each case for an amount equal to the fair market value of those interests.

Liquidation Stage

Upon our liquidation, our partners, including our General Partner, will be entitled to receive liquidating distributions according to their particular capital account
balances.

Ownership Interests in Our General Partner

HPIP controls and owns 77% and Magnolia Infrastructure Holdings, LLC, through its ownership in AMID GP Holdings, LLC, owns 23% of our General Partner.

In addition to the approximate 1.3% General Partner interest in us, our General Partner owns the incentive distribution rights, which entitle the holder to increasing
percentages, up to a maximum of 48.0% of the cash we distribute in excess of $0.4125 per unit per quarter.

Agreements with Affiliates

We  and  other  parties  have  or  may  enter  into  the  various  documents  and  agreements  with  certain  of  our  affiliates,  as  described  in  more  detail  below.  These
agreements have been negotiated among affiliated parties and, consequently, are not the result of arm's-length negotiations.

Business  Development  Activity.  For the  year  ended  December  31, 2017  ,  our  General  Partner  incurred  approximately  $0.8 million of costs related  to business
development compensation that were funded by the Partnership. As of December 31, 2017, the Partnership has been reimbursed for these costs. For the year ended
December  31,  2017  ,  our  General  Partner  incurred  approximately  less  than  $0.1  million  of  costs  associated  with  other  business  development  activities.  If  the

development costs related to that project.

periodically  review all  related-person  transactions  that are  required  to be disclosed  under SEC rules  and, when appropriate,  initially  authorize  or ratify  all  such
transactions. In the event that the Board of Directors of our General Partner or its authorized committee considers ratification of a related-person transaction and
determines  not  to  so  ratify,  the  code  of  business  conduct  and  ethics  will  provide  that  our  management  will  make  all  reasonable  efforts  to  cancel  or  annul  the
transaction.

The Code of Ethics, as updated on November 2, 2017, provides that, in determining whether to recommend the initial approval or ratification of a related-person
transaction,  the  Board  of  Directors  of  our  General  Partner  or  its  authorized  committee  should  consider  all  of  the  relevant  facts  and  circumstances  available,
including (if applicable) but not limited to: i) whether there is an appropriate business justification for the transaction; ii) the benefits that accrue to us as a result of
the transaction; iii) the terms available to unrelated third parties entering into similar transactions; iv) the impact of the transaction on director independence (in the
event the related person is a director, an immediate family member of a director or an entity in which a director or an immediate family member of a director is a
partner, shareholder, member or executive officer); v) the availability of other sources for comparable products or services; vi) whether it is a single transaction or
a series of ongoing, related transactions; and vii) whether entering into the transaction would be consistent with the code of business conduct and ethics.

In addition, our Partnership Agreement provides for the Conflicts Committee, as delegated by the Board as circumstances warrant, to review conflicts of interest
between us and our General Partner or between us and affiliates of our General Partner. If a matter is submitted to the Conflicts Committee, which will consist
solely  of  independent  directors,  for  their  review  and  approval,  the  Conflicts  Committee  will  determine  if  the  resolution  of  a  conflict  of  interest  that  has  been
presented to it by the Board of Directors of our General Partner is fair and reasonable to us. The members of the Conflicts Committee may not be executive officers
or employees of our General Partner or directors, executive officers or employees of its affiliates. In addition, the members of the Conflicts Committee must meet
the independence and experience standards established by the NYSE and the Exchange Act for service on an audit committee of a board of directors. Any matters
approved by the Conflicts Committee will be conclusively deemed to be fair and reasonable to us, approved by all of our partners and not a breach by our General
Partner of any duties it may owe us or our unitholders.

Report of Independent Registered Public Accounting Firm

To the Board of Directors of American Midstream GP, LLC and to the Unitholders of American Midstream Partners, LP

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of American Midstream Partners, LP and its subsidiaries (the “Partnership”) as of December 31,
2017 and 2016, and the related consolidated statements of operations, of comprehensive loss, of changes in equity, partners’ capital and noncontrolling interests
and  of  cash  flows  for  each  of  the  three  years  in  the  period  ended  December  31,  2017,  including  the  related  notes  (collectively  referred  to  as  the  “consolidated
financial statements”). We also have audited the Partnership's internal control over financial reporting as of December 31, 2017, based on criteria established in
Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In  our  opinion,  the  consolidated  financial  statements  referred  to  above  present  fairly,  in  all  material  respects,  the  financial  position  of  the  Partnership  as  of
December  31,  2017  and  2016,  and  the  results  of  their  operations  and  their  cash  flows  for  each  of  the  three  years  in  the  period  ended  December  31,  2017  in
conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Partnership did not maintain, in all material
respects,  effective  internal  control  over  financial  reporting  as  of  December  31,  2017,  based  on  criteria  established  in  Internal Control - Integrated  Framework
(2013) issued by the COSO because the following existed as of that date: (i) an ineffective control environment due to the lack of sufficient oversight of internal
control  over  financial  reporting  and  an  insufficient  complement  of  resources  with  an  appropriate  level  of  accounting  knowledge,  expertise  and  training
commensurate with the Partnership’s financial reporting requirements, which contributed to additional material weaknesses, as the Partnership did not (ii) design
and  maintain  effective  controls  over  the  accounting  for  complex,  non-routine  transactions  of  the  Partnership,  (iii)  design  and  maintain  effective  controls  over
revenue and receivables, (iv) design and maintain effective controls over acquisitions and divestitures, (v) design and maintain effective controls over the period
end financial reporting process, (vi) design and maintain effective controls over asset retirement obligations, goodwill, other intangible, and finite-lived assets, and
(vii) maintain effective controls over user access to ensure appropriate segregation of duties and that adequately restrict user and privileged access to a significant
application, programs, and data to appropriate Partnership personnel.

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a
material misstatement of the annual or interim financial statements will not be prevented or detected on a timely basis. The material weaknesses referred to above
are described in Management’s Annual Report on Internal Control over Financial Reporting appearing under Item 9A. We considered these material weaknesses in
determining the nature, timing, and extent of audit tests applied in our audit of the December 31, 2017 consolidated financial statements, and our opinion regarding
the effectiveness of the Partnership’s internal control over financial reporting does not affect our opinion on those consolidated financial statements.

Basis for Opinions

The Partnership's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for
its assessment of the effectiveness of internal control over financial reporting included in management's report referred to above. Our responsibility is to express
opinions  on  the  Partnership’s  consolidated  financial  statements  and  on  the  Partnership's  internal  control  over  financial  reporting  based  on  our  audits.  We  are  a
public  accounting  firm  registered  with  the  Public  Company  Accounting  Oversight  Board  (United  States)  ("PCAOB")  and  are  required  to  be  independent  with
respect to the Partnership 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  audits  to  obtain  reasonable
assurance  about  whether  the  consolidated  financial  statements  are  free  of  material  misstatement,  whether  due  to  error  or  fraud,  and  whether  effective  internal
control over financial reporting was maintained in all material respects.

Our  audits  of  the  consolidated  financial  statements  included  performing  procedures  to  assess  the  risks  of  material  misstatement  of  the  consolidated  financial
statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence
regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant
estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial
reporting  included  obtaining  an  understanding  of  internal  control  over  financial  reporting,  assessing  the  risk  that  a  material  weakness  exists,  and  testing  and
evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits

F-1

also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our
opinions.

As described in Management’s Annual Report on Internal Control over Financial Reporting, management has excluded JP Energy Partners, LP (“JPE”) from its
assessment of the Partnership’s internal control over financial reporting as of December 31, 2017 because it was acquired by the Partnership in a purchase business
combination during 2017. We have also excluded JPE from our audit of the Partnership’s internal control over financial reporting. JPE represents approximately
21.9% of consolidated assets and 51.4% of the consolidated revenues as of and for the year ended December 31, 2017.

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 (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions
and  dispositions  of  the  assets  of  the  company;  (ii)  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  (iii)  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.

American Midstream Partners, LP, and Subsidiaries

Notes to Consolidated Financial Statements

Organization

General

American Midstream Partners, LP and subsidiaries (the “Partnership”, “we”, “us”, or “our”) is a growth-oriented Delaware limited partnership that was formed on
August 20, 2009 to own, operate, develop and acquire a diversified portfolio of midstream energy assets. The Partnership’s general partner, American Midstream
GP,  LLC  (the  “General  Partner”),  is  77% owned  by  High  Point  Infrastructure  Partners,  LLC  (“HPIP”)  and  23% indirectly  owned  by  Magnolia  Infrastructure
Holdings, LLC, both of which are affiliates of ArcLight Capital Partners, LLC ("ArcLight"). Our capital accounts consist of notional General Partner units and
units representing limited partner interests.

Nature of business

We provide critical midstream infrastructure that links producers of natural gas, crude oil, NGLs, condensate and specialty chemicals to numerous intermediate and
end-use markets. Through our five reportable segments, (1) gas gathering and processing services, (2) liquid pipelines and services, (3) natural gas transportation
services, (4) offshore pipelines and services, and (5) terminalling services, we engage in the business of gathering, treating, processing, and transporting natural
gas; gathering, transporting, storing, treating and fractionating NGLs; gathering, storing and transporting crude oil and condensates and storing specialty chemical
products  and  refined  products.  Most  of  our  cash  flow  is  generated  from  fee-based  and  fixed-margin  compensation  for  gathering,  processing,  transporting  and
treating natural gas and crude oil, firm capacity reservation charges, interruptible transportation charges, guaranteed firm storage contracts, throughput fees and
other optional charges associated with ancillary services.

Our primary assets are strategically located in some of the most prolific onshore and offshore producing regions and key demand markets in the United States. Our
gathering and processing assets are primarily located in (i) the Permian Basin of West Texas, (ii) the Cotton Valley/Haynesville Shale of East Texas, (iii) the Eagle
Ford Shale of South Texas, (iv) the Bakken Shale of North Dakota, and (v) offshore in the Gulf of Mexico. Our transmission and terminal assets are in key demand
markets  in  Oklahoma,  Alabama,  Arkansas,  Louisiana,  Mississippi  and  Tennessee  and  in  the  Port  of  New  Orleans  in  Louisiana  and  the  Port  of  Brunswick  in
Georgia.

Basis of presentation

As  discussed  in  Note  3-  Acquisitions ,  we  acquired  JPE  in  a  unit-for-unit  exchange  on  March  8,  2017.  As  both  the  Partnership  and  JPE  were  controlled  by
ArcLight, the acquisition represents a transaction among entities under common control and has been accounted for as a common control transaction in a manner
similar to a pooling of interests. Although the Partnership is the legal acquirer, JPE is considered to be the acquirer for accounting purposes as ArcLight obtained
control  of  JPE  before  it  obtained  control  the  Partnership.  The  accompanying  financial  statements  represent  the  JPE  historical  cost  basis  financial  statements
retrospectively adjusted to reflect its acquisition of the Partnership at ArcLight’s historical cost basis effective April 15, 2013, the date on which ArcLight obtained
control of the Partnership.

Transactions between entities under common control

We may enter into transactions with ArcLight affiliates whereby we receive midstream assets or other businesses in exchange for cash or Partnership's equity. As
the transactions are between entities under common control we account for the net assets acquired at the affiliate's historical cost basis, whether the transactions are
considered  assets  or  business  acquisitions.  In  certain  cases,  our  historical  financial  statements  will  be  revised  to  include  the  results  attributable  to  the  assets
acquired from the later of April 15, 2013 (the date Arclight affiliates obtained control of our General Partner) or the date the ArcLight affiliates obtained control of
the assets or business acquired.

Consolidation policy

The accompanying consolidated financial statements include accounts of American Midstream Partners, LP, and its controlled subsidiaries. All significant inter-
company accounts and transactions have been eliminated in the preparation of the accompanying consolidated financial statements.

Summary of Significant Accounting Policies

Use of estimates

When  preparing  consolidated  financial  statements  in  conformity  with  accounting  principles  generally  accepted  in  the  United  States  of  America  ("GAAP"),
management must make estimates and assumptions based on information available at the time. These estimates and assumptions affect the reported amounts of
assets,  liabilities,  revenues  and  expenses,  as  well  as  the  disclosures  of  contingent  assets  and  liabilities  as  of  the  date  of  the  financial  statements.  Estimates  and
assumptions are based on information available at the time such estimates and assumptions are made. Adjustments made with respect to the use of these estimates
and assumptions often relate to information not previously available. Uncertainties with respect to such estimates and assumptions are inherent in the preparation
of financial statements. Estimates and assumptions are used in, among other things, i) estimating unbilled revenues, product purchases and operating and general
and  administrative  costs,  ii)  developing  fair  value  assumptions,  including  estimates  of  future  cash  flows  and  discount  rates,  iii)  analyzing  long-lived  assets,
goodwill and intangible assets for possible impairment, iv) estimating the useful lives of assets and v) determining amounts to accrue for contingencies, guarantees
and indemnifications. Actual results, therefore, could differ materially from estimated amounts.

Cash, cash equivalents and restricted cash

We consider all highly liquid investments with an original maturity of three months or less at the date of purchase to be cash equivalents. The carrying value of
cash and cash equivalents approximates fair value because of the short term to maturity of these investments. From time to time we are required to maintain cash in
separate accounts the use of which is restricted by the terms of our debt agreements or asset retirement obligations. Such amounts are included in Restricted cash in
our consolidated balance sheets.

Inventory

Inventory, which is mainly comprised of crude oil, refined products and NGLs, is stated at the lower of cost or net realizable value. Cost of crude oil, NGLs and
refined products inventory is determined using the first-in, first-out (FIFO) method.

Allowance for doubtful accounts

We  establish  provisions  for  losses  on  accounts  receivable  when  we  determine  that  we  will  not  collect  all  or  part  of  an  outstanding  balance.  Collectability  is
reviewed  regularly  and  an  allowance  is  established  or  adjusted,  as  necessary,  using  the  specific  identification  method.  We  recorded  allowances  for  doubtful
accounts of $0.2 million and $ 0.6 million , respectively, as of December 31, 2017 and 2016. Bad debt expense for the years ended December 31, 2017, 2016 and
2015 was approximately $0.1 million , $0.6 million and $0.0 million , respectively, which is excluding the impact of the sale of the Propane Business.

Derivative financial instruments

Our net income (loss) and cash flows are subject to volatility stemming from changes in interest rates on our variable rate debt, commodity prices and fractionation
margins (the relative difference between the price we receive from NGL sales and the corresponding cost of natural gas purchases). In an effort to manage the risks
to unitholders, we may use a variety of derivative financial instruments such as swaps, collars, interest rate caps or forward contracts to create offsetting positions
to specific commodity or interest rate exposures. We record all derivative financial instruments in our consolidated balance sheets at fair value as current and long-
term  assets  or  liabilities  on  a  net  basis  by  counterparty.  We  record  changes  in  the  fair  value  of  our  commodity  derivatives  in  Gains  (losses)  on  commodity
derivatives, net while changes in the fair value of our interest rate swaps are included in Interest expense in our consolidated statements of operations.

Our hedging program provides a control structure and governance for our hedging activities specific to identified risks and time periods, which are subject to the
approval and monitoring by the Board of Directors of our General Partner. We employ derivative financial instruments in connection with an underlying asset,
liability or anticipated transaction, and we do not use derivative financial instruments for speculative or trading purposes.

The  price  assumptions  we  use  to  value  our  derivative  financial  instruments  can  affect  our  net  income  (loss)  each  period.  We  use  published  market  price
information where available, or quotations from over-the-counter, market makers to find executable bids and offers. The valuations also reflect the potential impact
of related conditions, including credit risk of our counterparties. The amounts reported in our consolidated financial statements change quarterly as these valuations
are revised to reflect actual results, changes in market conditions or other factors, many of which are beyond our control.

F-10

We are also a party to a number of contracts  that have elements of a derivative instrument.  These contracts are primarily forward crude oil purchase and sales
contracts  with  counterparties.  Although  many  of  these  contracts  have  the  requisite  elements  of  a  derivative  instrument,  these  contracts  qualify  for  the  normal
purchase and normal sales exception because they provide for the delivery of products or services in quantities that are expected to be used in the normal course of
operating our business and the price in the contract is based on an underlying that is directly associated with the price of the product or service being purchased or
sold. As a result, these contracts are not recorded in our consolidated financial statements until they are settled.

Fair value measurements

We  apply  the  authoritative  accounting  provisions  for  measuring  the  fair  value  of  our  derivative  financial  instruments  and  disclosures  associated  with  our
outstanding  indebtedness.  We  define  fair  value  as  an  exit  price  representing  the  expected  amount  we  would  receive  when  selling  an  asset  or  pay  to  transfer  a
liability in an orderly transaction with market participants at the measurement date.

We use various assumptions and methods in estimating the fair values of our financial instruments. The carrying amounts of cash and cash equivalents, accounts
receivable and accounts payable approximated their fair value due to the short-term maturity of these instruments.

We  employ  a  hierarchy  which  prioritizes  the  inputs  we  use  to  measure  recurring  fair  value  into  three  distinct  categories  based  upon  whether  such  inputs  are
observable in active markets or unobservable. We classify assets and liabilities in their entirety based on the lowest level of input that is significant to the fair value
measurement.  Our  methodology  for  categorizing  assets  and  liabilities  that  are  measured  at  fair  value  pursuant  to  this  hierarchy  gives  the  highest  priority  to
unadjusted quoted prices in active markets and the lowest level to unobservable inputs as outlined below:

•
•
•

Level 1 – Inputs represent unadjusted quoted prices in active markets for identical assets or liabilities;
Level 2 – Inputs include quoted prices for similar assets and liabilities in active markets that are either directly or indirectly observable; and
Level 3 – Inputs are unobservable and considered significant to fair value measurement.

We  utilize  a  mid-market  pricing  convention,  or  the  "market  approach,"  for  valuation  for  assigning  fair  value  to  our  derivative  assets  and  liabilities.  Our  credit
exposure  for  over-the-counter  derivatives  is  directly  with  our  counterparty  and  continues  until  the  maturity  or  termination  of  the  contracts.  As  appropriate,
valuations are adjusted for various factors such as credit and liquidity considerations.

Property, plant and equipment

We capitalize expenditures related to property, plant and equipment that have a useful life greater than one year. We also capitalize expenditures that improve or
extend the useful life of an asset. Maintenance and repair costs, including any planned major maintenance activities, are expensed as incurred.

We record property, plant, and equipment at cost and recognize depreciation expense on a straight-line basis over the related estimated useful lives of the assets
which range from 3 to 40 years. Our determination of the useful lives of property, plant and equipment requires us to make various assumptions, including the
supply of and demand for hydrocarbons in the markets served by our assets, normal wear and tear of the facilities, and the extent and frequency of maintenance
programs. We record depreciation using the group method of depreciation, which is commonly used by pipelines, utilities and similar assets.

We classify long-lived assets to be disposed of through sales that meet specific criteria as held for sale. We cease depreciating those assets effective on the date the
asset is classified as held for sale. We record those assets at the lower of their carrying value or the estimated fair value less the cost to sell. Until the assets are
disposed of, our estimate of fair value is re-determined when related events or circumstances change.

Impairment of long lived Assets

We evaluate the recoverability of our property, plant and equipment and intangible assets with definite lives when events or circumstances indicate we may not
recover the carrying amount of the assets. We continually monitor our operations, the market, and business environment to identify indicators that could suggest an
asset or asset group may not be recoverable. We evaluate the asset or asset group for recoverability by estimating the undiscounted future cash flows expected to be
derived  from  their  use  and  disposition.  These  cash  flow  estimates  require  us  to  make  projections  and  assumptions  for  many  years  into  the  future  for  pricing,
demand, competition, operating cost, contract renewals, and other factors. An asset or asset group is considered impaired

F-11

when  the  estimated  undiscounted  cash  flows  are  less  than  the  carrying  amount.  In  that  event,  an  impairment  loss  is  recognized  to  the  extent  that  the  carrying
amount of the asset or asset group exceeds its fair value as determined by quoted market prices in active markets or present value techniques. The determination of
fair values using present value techniques requires us to make projections and assumptions regarding future cash flows and weighted average cost of capital. Any
changes  we  make  to  these  projections  and  assumptions  could  result  in  significant  revisions  to  our  evaluation  of  the  recoverability  of  our  property,  plant  and
equipment and the recognition of an impairment loss in our consolidated statements of operations.

Goodwill impairment

We record goodwill for the excess of the cost of an acquisition over the fair value of the net assets of the acquired business. Goodwill is reviewed for impairment at
least annually or more frequently if an event or change in circumstance indicates that an impairment may have occurred. Impairment of goodwill is the condition
that  exists  when  the  carrying  amount  of  goodwill  exceeds  its  fair  value  and  a  goodwill  impairment  loss  is  recognized  for  the  amount  that  the  carrying  amount
exceeds its fair value. On an annual basis, or more frequently if needed, a qualitative review (Step Zero) is used to evaluate whether a condition for impairment
exists. If it is the case, a quantitative impairment test (Step One) is then performed to identify goodwill impairment and measure the amount of impairment loss to
be recognized, if any.

Intangible assets

We  record  the  estimated  fair  value  of acquired  customer  contracts,  relationships  and dedicated  acreage  agreements  as  intangible  assets.  These intangible  assets
have definite lives and are subject to amortization on a straight-line basis over their economic lives, currently ranging between five years and thirty years . We
assess intangible assets for impairment together with related underlying long-lived assets whenever events or changes in circumstances indicate that the carrying
amount of an asset may not be recoverable.

Investment in unconsolidated affiliates

We hold membership interests in entities that own and operate natural gas pipeline systems and NGL and crude oil pipelines in and around Louisiana, Alabama,
Mississippi and the Gulf of Mexico. While we have significant influence over these entities, we do not control them and therefore, they are accounted for using the
equity method and are reported in  Investment in unconsolidated affiliates  in the consolidated balance sheets. We evaluate the recoverability of these investments
on a regular basis and recognize impairment write downs if we determine a loss in value represents an other-than-temporary-decline. The unconsolidated affiliates
that were determined to be variable interest entities (“VIE”) due to disproportionate economic interests and decision making rights were further evaluated under the
VIE  method  of  consolidation.  In  each  case,  we  lack  the  power  to  direct  the  activities  that  most  significantly  impact  the  unconsolidated  affiliate’s  economic
performance.  Therefore,  as  we  do  not  hold  a  controlling  financial  interest  in  these  affiliates,  we  account  for  our  related  investments  using  the  equity  method.
Additionally, our maximum exposure to loss related to each entity is limited to our equity investment as presented on the consolidated balance sheets as of the
balance sheet date. In each case, we are not obligated to absorb losses greater than our proportional ownership percentages. Our right to receive residual returns is
not  limited  to  any  amount  less  than  the  ownership  percentages.  We  also  have  a  joint  venture  arrangement  in  which  we  and  our  partners  share  proportional
ownership and responsibilities and receive returns in accordance with our ownership percentage.

Deferred financing costs

Costs incurred in connection with our revolving credit facilities are deferred and charged to interest expense over the term of the related credit agreement. Such
amounts are included in Other assets, net in our consolidated balance sheets. Costs incurred in connection with our long-term debt such as the 8.50% Senior Notes
and 3.77% Senior Notes are also deferred and charged to interest expense over the respective term of the agreements; however, these amounts are reflected as a
reduction of the related obligation. Gains or losses on debt repurchases or extinguishment include any associated unamortized deferred financing costs.

Asset retirement obligations

Asset  retirement  obligations  ("ARO")  are  legal  obligations  associated  with  the  retirement  of  tangible  long-lived  assets  that  result  from  the  asset's  acquisition,
construction,  development  and  operation.  An  ARO  is  initially  measured  at  its  estimated  fair  value.  Upon  initial  recognition,  we  also  record  an  increase  to  the
carrying  amount  of  the  related  long-lived  asset.  We  depreciate  the  asset  using  the  straight-line  method  over  the  period  during  which  it  is  expected  to  provide
benefits. After initial recognition, we revise the ARO to reflect the passage of time and for changes in the estimated amount or timing of cash flows.

We have legal obligations requiring us to decommission our offshore pipeline systems at retirement. In certain rate jurisdictions, we are permitted to include annual
charges for removal costs in the regulated cost of service rates we charge our customers.

F-12

Additionally, legal obligations exist for certain of our onshore right-of-way agreements due to requirements or landowner options to compel us to remove the pipe
at  final  abandonment.  Sufficient  data  exists  with  certain  onshore  pipeline  systems  to  reasonably  estimate  the  cost  of  abandoning  or  retiring  a  pipeline  system.
However, in some cases, there is insufficient information to reasonably determine the timing and/or method of settlement for purposes of estimating the fair value
of the asset retirement obligation. In these cases, the asset retirement obligation cost is considered indeterminate because there is no data or information that can be
derived  from  past  practice,  industry  practice,  management's  experience,  or  the  asset's  estimated  economic  life.  The  useful  lives  of  most  pipeline  systems  are
primarily derived from available supply resources and ultimate consumption of those resources by end users. Variables can affect the remaining lives of the assets
which preclude us from making a reasonable estimate of the asset retirement obligation. Indeterminate asset retirement obligation costs will be recognized in the
period in which sufficient information exists to reasonably estimate potential settlement dates and methods.

Commitments, contingencies and environmental liabilities

We expense or capitalize, as appropriate, expenditures for ongoing compliance with environmental regulations that relate to past or current operations. We expense
amounts  we  incur  from  the  remediation  of  existing  environmental  contamination  caused  by  past  operations  that  do  not  benefit  future  periods  by  preventing  or
eliminating future contamination. We record liabilities for environmental matters when assessments indicate that remediation efforts are probable and the costs can
be  reasonably  estimated.  Estimates  of  environmental  liabilities  are  based  on  currently  available  facts,  existing  technology  and  presently  enacted  laws  and
regulation  taking  into  consideration  the  likely  effects  of  inflation  and  other  factors.  These  amounts  also  take  into  account  our  prior  experience  in  remediating
contaminated sites, other companies' clean-up experience and data released by government organizations. Our estimates are subject to revision in future periods
based on actual cost or new information. We evaluate recoveries from insurance coverage separately from the liability and, when recovery is probable, we record
an asset separately from the associated liability in our consolidated financial statements.

We recognize liabilities for other commitments and contingencies when, after fully analyzing the available information, we determine it is probable that a liability
has been incurred and the amount of loss can be reasonably estimated. When a range of probable loss can be estimated, we accrue the most likely amount or if no
amount is more likely than another, we accrue the minimum of the range of probable loss. We expense legal costs associated with loss contingencies as such costs
are incurred.

Noncontrolling interests

Noncontrolling interests represent the minority interest holders' proportionate share of the equity in certain of our consolidated subsidiaries and are adjusted for the
minority interest holders' proportionate share of the subsidiaries' earnings or losses each period.

Revenue recognition

We  recognize  revenue  from  the  sale  of  commodities  (e.g.,  natural  gas,  crude  oil,  NGLs  or  condensate)  as  well  as  from  the  provision  of  gathering,  processing,
transportation or storage services when all of the following criteria are met: i) persuasive evidence of an exchange arrangement exists, ii) delivery has occurred or
services have been rendered, iii) the price is fixed or determinable, and iv) collectability is reasonably assured. We recognize revenue from the sale of commodities
and the related cost of product sold on a gross basis for those transactions where we act as the principal and take title to commodities that are purchased for resale.
See  Note  2  -  Recent  Accounting  Pronouncements,  for  further  discussion  regarding  our  implementation  of  the  new  Revenue  Recognition  guidance  beginning
January 1, 2018.

Cost of sales

Cost of sales represent the cost of commodities purchased for resale or obtained in connection with certain of our customer revenue arrangements. These costs do
not include an allocation of depreciation expense or direct operating costs.

Corporate expenses

Corporate  expenses  include  compensation  costs  for  executives  and  administrative  personnel,  professional  service  fees,  rent  expense  and  other  general  and
administrative expenses and are recognized as incurred.

F-13

                                                 
Operational balancing agreements and natural gas imbalances

To  facilitate  deliveries  of  natural  gas  and  provide  for  operational  flexibility,  we  have  operational  balancing  agreements  in  place  with  other  interconnecting
pipelines. These agreements ensure that the volume of natural gas a shipper schedules for transportation between two interconnecting pipelines equals the volume
actually  delivered.  If  natural  gas  moves  between  pipelines  in  volumes  that  are  more  or  less  than  the  volumes  the  shipper  previously  scheduled,  a  natural  gas
imbalance is created. The imbalances are settled through periodic cash payments or repaid in-kind through future receipt or delivery of natural gas. Natural gas
imbalances are recorded in Other current assets or Accrued expenses and other current liabilities on our consolidated balance sheets at cost which approximates
fair value.

Equity-based compensation

We  award  equity-based  compensation  to  management,  non-management  employees  and  directors  under  our  long-term  incentive  plans,  which  provide  for  the
issuance  of  options,  unit  appreciation  rights,  restricted  units,  phantom  units,  other  unit-based  awards,  unit  awards  or  replacement  awards,  as  well  as  tandem
Distribution Equivalent Rights ("DERs"). Compensation expense is measured by the fair value of the award at the date of grant as determined by management.
Compensation expense is recognized in Corporate expenses and Direct operating expenses over the requisite service period of each award.

Income taxes

The Partnership is not a taxable entity for U.S. federal income tax purposes or for the majority of states that impose an income tax. Taxes on our net income are
generally  borne  by  our  unitholders  through  the  allocation  of  taxable  income.  American  Midstream  Blackwater,  LLC,  a  subsidiary  of  the  Partnership,  owns  a
subsidiary that has operations which are subject to both U.S. federal and state income taxes. We account for income taxes of that subsidiary using the asset and
liability approach. If it is more than likely that a deferred tax asset will not be realized, a valuation allowance is recognized.

Margin tax expense results from the enactment of laws by the State of Texas that apply to entities organized as partnerships and is included in Income tax expense
in our consolidated statements of operations. The Texas margin tax is computed on the portion of our taxable margin which is apportioned to Texas.

Net income (loss) for financial statement purposes may differ significantly from taxable income (loss) allocable to unitholders as a result of differences between
the  financial  reporting  and  income  tax  bases  of  our  assets  and  liabilities  and  the  taxable  income  allocation  requirement  under  our  Partnership  Agreement.  The
aggregate  difference  in  the  basis  of  our  net  assets  for  financial  and  tax  reporting  purposes  cannot  be  readily  determined  because  information  regarding  each
partner's tax attributes in us is not available.

Accumulated other comprehensive income (loss)

Accumulated other comprehensive income (loss) is comprised solely of adjustments related to the Partnership's postretirement benefit plan.

Limited partners' net income (loss) per unit

We  compute  earnings  per  unit  using  the  two-class  method.  The  two-class  method  requires  that  securities  that  meet  the  definition  of  a  participating  security  be
considered for inclusion in the computation of basic earnings per unit. Under the two-class method, earnings per unit is calculated as if all of the earnings for the
period were distributed under the terms of the Partnership Agreement, regardless of whether the General Partner has discretion over the amount of distributions to
be made in any particular period, whether those earnings would actually be distributed during a particular period from an economic or practical perspective, or
whether the General Partner has other legal or contractual limitations on its ability to pay distributions that would prevent it from distributing all of the earnings for
a particular period.

The two-class method does not impact our overall net income or other financial results; however, in periods in which aggregate net income exceeds our aggregate
distributions  for  such  period,  it  will  have  the  impact  of  reducing  net  income  per  limited  partner  unit.  This  result  occurs  as  a  larger  portion  of  our  aggregate
earnings, as if distributed, is allocated to the incentive distribution rights of the General Partner, even though we make distributions on the basis of available cash
and not earnings. In periods in which our aggregate net income does not exceed our aggregate distributions for such period, the two-class method does not have
any impact on our calculation of earnings per limited partner unit.

2. New Accounting Pronouncements

Adopted in 2017

In  January  2017,  the  FASB  issued  ASU  No.  2017-01  ,  “Business  Combinations  (Topic  805):  Clarifying  the  Definition  of  a  Business”.  The  guidance  provides
criteria for use in determining when to conclude an integrated  “set of assets and activities (as defined in the original guidance) being acquired or disposed in a
transaction" is not a business. Where the criteria are not met, more stringent screening has been provided to define a set as a business without an output, as more
narrowly defined within the guidance. ASU No. 2017-01 is effective for annual periods beginning after December 15, 2017, including interim periods within those
periods. The amendments should be applied prospectively on or after the effective date. Early adoption is permitted. We elected to early adopt ASU No. 2017-01
on October 1, 2017.

In January 2017, the FASB issued ASU No. 2017-04 , “Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment” , in which
the guidance on testing for goodwill was updated by the elimination of Step 2 in the determination on whether goodwill should be considered impaired. The annual
and/or  interim  assessments  are  still  required  to  be  completed.  Further,  the  guidance  eliminates  the  requirement  to  assess  reporting  units  with  zero  or  negative
carrying  values,  however,  the  carrying  values  for  all  reporting  units  must  be  disclosed.  ASU  No.  2017-04  is  effective  for  annual  or  any  interim  goodwill
impairment tests beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after
January  1,  2017.  We  elected  to  early  adopt  the  guidance  in  connection  with  our  annual  assessment  performed  in  October  2017  using  the  required  prospective
method.

To Be Adopted in 2018 or Later

In May 2014, the FASB issued Accounting Standards Update (“ASU”) No. 2014-09, “ Revenue from Contracts with Customers (Topic 606) ”, with the intent of
significantly enhancing consistency and comparability  of revenue recognition practices across entities and industries. ASU No. 2014-09 supersedes the revenue
recognition guidance in Topic 605, Revenue Recognition. The new standard establishes a single, principle-based five-step model to be applied to all contracts with
customers  and  introduces  new  and  enhanced  disclosure  requirements.  It  also  requires  the  use  of  more  estimates  and  judgments  than  the  present  standards  in
addition to additional disclosures. We have reviewed our various customer arrangements in order to determine the impact the new accounting guidance for revenue
recognition will have on our consolidated financial statements and related disclosures. We also engaged a third-party consulting firm to assist us with all the three
phases of adoption of the new guidance (Impact Assessment, Convert and Implement). We adopted the new standard on its effective date January 1, 2018 using the
modified retrospective method of adoption.

Based on our assessment, the application of the new standard will result in the following changes to our consolidated financial statements and revenue recognition
methods:

•

•

Estimates  of  variable  consideration  which  will  be  required  under  the  new  standard  as  well  as  the  allocation  of  the  transaction  price  for  certain  revenue
contracts may result in changes to the pattern or timing of revenue recognition for those contracts,and

Certain  payments  received  from  customers  to  offset  the  cost  of  constructing  assets  required  to  provide  services  to  those  customers,  referred  to  as
Contributions in Aid of Construction (CIAC) were previously recognized as incurred. Under the new standard, CIAC is deemed to be advance payments for
services and must be recognized when those future services are provided. CIAC will be accounted for as deferred revenue and recognized over the term of
the associated revenue contract.

Upon adoption as of January 1, 2018, we will recognize a cumulative effect of initially applying the new standard as a decrease in the opening balance of partners'
capital of approximately $11 million .

In February 2016, the FASB issued ASU No. 2016-02 (Topic 842) " Leases ", which supersedes the lease recognition requirements in ASC Topic 840, "Leases".
Under ASU No. 2016-02 lessees are required to recognize assets and liabilities on the balance sheet for most leases and provide enhanced disclosures. Leases will
continue  to  be  classified  as  either  finance  or  operating.  ASU  No.  2016-02  is  effective  for  annual  reporting  periods,  and  interim  periods  within  those  years
beginning after December 15, 2018. Entities are required to use a modified retrospective approach for leases that exist or are entered into after the beginning of the
earliest  comparative  period  in  the  financial  statements,  and  there  are  certain  optional  practical  expedients  that  an  entity  may  elect  to  apply.  Full  retrospective
application is prohibited and early adoption by public entities is permitted. We are in the process of evaluating the impact of ASU No. 2016-02 on our consolidated
financial statements as we will be required to reflect our various lease obligations and associated asset use rights on our consolidated balance sheets. The adoption
may also impact our debt covenant compliance and may require us to modify or replace certain of our existing information systems. We are engaging a third-party
consulting firm to assist us with the adoption of the new guidance and are currently in the Impact Assessment phase. We are not

F-15

yet able to determine whether the adoption of this standard will have a material impact on our consolidated financial statements and related disclosures, including
additional changes, if any, to our accounting system to capture data for disclosures purpose. We will adopt the guidance on its effective date January 1, 2019.

In August 2016, the FASB issued ASU No. 2016-15, " Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments ", a
consensus of the FASB’s Emerging Issues Task Force. The new guidance which requires application using a retrospective transition method is intended to reduce
diversity in practice in how certain transactions are classified in the statement of cash flows. The ASU addresses how the following cash transactions are presented:
(1) debt prepayment or debt extinguishment costs; (2) settlement of zero-coupon debt instruments; (3) contingent consideration payments made after a business
combination; (4) proceeds from the settlement of insurance claims; (5) proceeds from the settlement of corporate-owned life insurance policies; (6) distributions
received  from  equity  method  investments;  (7)  beneficial  interests  in  securitization  transactions  and  (8)  cash  receipts  and  cash  payments  that  have  aspects  of
multiple cash flow classifications. The impact of adopting the new guidance to our consolidated statements of cash flows using the retrospective transition method
would be a) immaterial to Net cash provided by operating activities and Net cash provided by (used in) financing activities, and material to Net cash provided by
(used in) investing activities for the year ended December 31, 2017, b) immaterial to Net cash provided by operating activities and Net cash provided by (used in)
financing  activities  and  material  to  Net  cash  provided  by  (used  in)  investing  activities  for  the  year  ended  December  31,  2016  and  c)  no ne  for  the  year  ended
December 31, 2015. We adopted the standard upon its effective date January 1, 2018.

In November 2016, the FASB issued ASU No. 2016-18, “ Statement of Cash Flows (Topic 230): Restricted Cash” , which aims to improve the disclosure of the
change  during  the  period  in  total  cash,  cash  equivalents  and  amounts  generally  described  as  restricted  cash  or  restricted  cash  equivalents.  Amounts  generally
described as restricted cash or restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-
period total amounts on the statement of cash flows. The standard is effective beginning first quarter of 2018. Any adjustments required in adoption of this standard
should be reflected as of the beginning of the fiscal year that includes the interim period and should be applied using a retrospective  transition method to each
period. As our restricted cash balances as of December 31, 2017 and 2016 were material, we have determined that the impact of this standard on our consolidated
statements  of  cash  flows  and  related  disclosures  would  be  material  for  such  periods,  considering  the  standard  requires  retrospective  application.  The  impact  of
adopting the new guidance to our consolidated statements of cash flows using the retrospective transition method would be a) immaterial to Net cash provided by
operating activities and Net cash provided by (used in) financing activities, and material to Net cash provided by (used in) investing activities for the years ended
December 31, 2017 and 2016 and b) immaterial for the year ended December 31, 2015. We adopted the standard on its effective date of January 1, 2018.

In May 2017, the FASB issued ASU No. 2017-09 , “Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting” , to provide guidance
about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting. Pursuant to this ASU, an entity
should account for the effects of a modification unless all the following are met: (1) the fair value (or calculated value or intrinsic value, if such an alternative
measurement method is used) of the modified award is the same as the fair value (or calculated value or intrinsic value, if such an alternative measurement method
is used) of the original award immediately before the original award is modified (if the modification does not affect any of the inputs to the valuation technique that
the entity uses to value the award, the entity is not required to estimate the value immediately before and after the modification); (2) the vesting conditions of the
modified award are the same as the vesting conditions of the original award immediately before the original award is modified; and (3) the classification of the
modified award as an equity instrument or a liability instrument is the same as the classification of the original award immediately before the original award is
modified. ASU No. 2017-09 is effective for annual periods beginning after December 15, 2017, including interim periods within those periods. This update should
be applied prospectively to an award modified on or after the adoption date. We adopted the guidance on its effective date January 1, 2018. Based on historical
patterns  of  our  granted  unit-based  awards,  which  did  not  involve  material  modifications,  we  do  not  believe  that  the  impact  of  this  update  on  our  consolidated
financial statements and related disclosures will be material.

In January 2018, the FASB issued ASU No. 2018-01 “ Leases - Land Easement Practical Expedient for Transition to Topic 842 ”, to provide an optional transition
practical expedient to not evaluate under Topic 842 existing or expired land easements that were not previously accounted for as leases under the current guidance
in Topic 840. An entity that elects this practical expedient should evaluate new or modified land easements under Topic 842 beginning at the date that the entity
adopts Topic 842. An entity that does not elect this practical expedient should evaluate all existing or expired land easements in connection with the adoption of the
new lease requirements in Topic 842 to assess whether they meet the definition of a lease. As discussed above, we are engaging a third-party consulting firm to
assist us with the adoption of the new guidance and are currently in the Impact Assessment phase. We are not yet able to determine whether we would elect this
practical expedient or whether the adoption of this standard will have a material impact on our consolidated financial statements and related disclosures, including
additional changes, if any, to our accounting system to capture data for disclosures purpose. We will adopt this on its effective date January 1, 2019.

F-16

In March 2018, the FASB issued ASU No. 2018-05 “ Income Taxes (Topic 740): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No.
118 (SEC Update) ”, to provide guidance for companies that have not completed their accounting for the income tax effects of the Tax Cuts and Jobs Act in the
period of enactment. The measurement period begins in the reporting period that includes the Act’s enactment date December 22, 2017, and ends when a company
has obtained, prepared and analyzed the information needed to complete the accounting requirements under ASC 740 and should not extend beyond one year from
the enactment date. The impact of adopting the new guidance on our consolidated financial statements and related disclosures was immaterial.

3. Acquisitions

Delta House Investment

On September 18, 2015, the Partnership acquired a 26.3% interest in Pinto Offshore Holdings, LLC ("Pinto"), an entity that owns 49% of the Class A units of
Delta House, a floating production system platform with associated crude oil and gas export pipelines, located in the Mississippi Canyon region of the deepwater
Gulf of Mexico. We acquired our 26.3% non-operated interest in Pinto in exchange for $ 162.0 million in cash, funded by the proceeds of a public offering of 7.5
million of  the  Partnership's  common  units  and  with  borrowings  under  our  Credit  Agreement,  as  defined  in  Note  14  -  Debt Obligations. As  a  result,  we  own  a
minority interest in Pinto, which represents an indirect interest in 12.9% of the Class A units of Delta House. Pursuant to the Pinto LLC Agreement, we have no
management control or authority over the day-to-day operations.

Because  our  interest  in  Delta  House  was  previously  owned  by  an  ArcLight  affiliate,  we  recorded  our  investment  at  the  affiliate's  historical  cost  basis  of  $65.7
million in Investments in unconsolidated affiliates in our consolidated balance sheets and as an investing activity within the related consolidated statements of cash
flows.  The  amount  by  which  the  total  consideration  exceeded  the  affiliate's  historical  cost  basis  was  $96.3  million  and  is  recorded  as  a  distribution  within  the
consolidated statements of changes in equity, partners’ capital and noncontrolling interests and as a financing activity in the consolidated statements of cash flows.

On  April  25,  2016,  the  Partnership  increased  its  investment  in  Delta  House  through  the  purchase  of  100% of  the  outstanding  membership  interests  in  D-Day
Offshore Holdings, LLC (“D-Day”), an Arclight affiliate which owned 1.0% of Class A units of Delta House in exchange for approximately $9.9 million in cash
funded with borrowings under our Credit Agreement.

Because the additional investment in Delta House was previously owned by an ArcLight affiliate, we recorded our investment in D-Day at the affiliate’s historical
cost  basis  of  $9.9  million  in Investments  in  unconsolidated  affiliates  on  our  consolidated  balance  sheets  and  as  an  investing  activity  within  our  consolidated
statements of cash flows.

On October 31, 2016, D-Day acquired an additional 6.2% direct interest in Class A units of Delta House from unrelated parties for approximately $48.8 million
which  was  funded  with  $34.5  million  in  net  proceeds  from  the  issuance  of  2,333,333 Series  D  convertible  preferred  units  ("Series  D  Units")  to  an  ArcLight
affiliate, plus $14.3 million in cash funded with borrowings under our Credit Agreement. Our share of Delta House earnings is reported in the Offshore Pipelines
and Services segment gross margin.

On September 29, 2017, we acquired an additional  15.5%  equity interest in Class A units of Delta House from affiliates of ArcLight for total cash consideration
of approximately  $125.4 million .  As our  15.5%  interest in Delta House was previously owned directly by ArcLight, we have accounted for our investment at
our  affiliate's  carry-over  basis  resulting  in    $49.8  million   recorded  in    Investments  in  unconsolidated  affiliates  in  our  consolidated  balance  sheets,  and  as  an
investing activity within the related consolidated statements of cash flows. The amount by which the total consideration exceeded the carry-over basis was  $75.6
million  and  was  recorded  as  a  distribution  to  our  general  partner  within  the  consolidated  statements  of  changes  in  equity,  partners’  capital  and  noncontrolling
interests and a financing activity in the consolidated statements of cash flows.

As of December 31, 2017, the Partnership and ArcLight indirectly own a 35.7% and 23.3% interest, respectively, in Delta House. Such 35.7% interest, includes a
35.7% interest in Delta House FPS LLC (“FPS”), which entitles us to receive 100% of the distributions from FPS until a certain payout threshold is met. Once the
payout threshold is met, approximately 7% of the distributions from FPS will be paid to the Class B membership interests in FPS.

For  the  year  ended  December  31,  2017  ,  the  Partnership  recorded  $41.3  million  in  equity  earnings  from  Delta  House.  The  Partnership  also  received  cash
distributions of  $43.7 million during the year. The excess of the cash distributions received over the earnings recorded from Delta House is classified as a return of
capital within cash flows from investing activities in our consolidated statements of cash flows.

F-17

Our interest in Pinto is accounted for as an equity method investment in the consolidated financial statements.

Emerald Transactions

On April 25, 2016 and April 27, 2016, American Midstream Emerald, LLC (“Emerald”), a wholly-owned subsidiary of the Partnership, entered into two purchase
and sale agreements with Emerald Midstream, LLC, an ArcLight affiliate, for the purchase of membership interests in certain midstream entities.

On April 25, 2016, Emerald entered into the first purchase and sale agreement for the purchase of membership interests in entities that own and operate natural gas
pipeline systems and NGL pipelines in and around Louisiana, Alabama, Mississippi, and the Gulf of Mexico (the “Pipeline Purchase Agreement”). Pursuant to the
Pipeline Purchase Agreement, Emerald acquired (i) 49.7% of the issued and outstanding membership interests of Destin, (ii) 16.7% of the issued and outstanding
membership interests of Tri-States, and (iii) 25.3% of the issued and outstanding membership interests of Wilprise, in exchange for approximately $183.6 million
(the “Pipeline Transaction”).

The Destin pipeline is a FERC-regulated, 255 -mile natural gas transportation system with total capacity of 1.2 Bcf/d. The system originates offshore in the Gulf of
Mexico and includes connections with four producing platforms and six producer-operated laterals, including Delta House. The 120 -mile offshore portion of the
Destin system terminates at the Pascagoula processing plant, which is owned by Enterprise Products Partners, LP, and is the single source of raw natural gas to the
plant.  The  onshore  portion  of  Destin  is  the  sole  delivery  point  for  merchant-quality  gas  from  the  Pascagoula  processing  plant  and  extends  135 miles  north  in
Mississippi. Destin currently serves as the primary transfer of gas flows from the Barnett and Haynesville shale plays to Florida markets through interconnections
with  major  interstate  pipelines.  Contracted  volumes  on  the  Destin  pipeline  are  based  on  life-of-field  dedications,  dedicated  volumes  over  a  given  period,  or
interruptible volumes as capacity permits. We became the operator of the Destin pipeline on November 1, 2016. The Tri-States pipeline is a FERC-regulated, 161 -
mile NGL pipeline and sole form of transport to Louisiana-based fractionators for NGLs produced at the Pascagoula plant served by Destin and other facilities.
The Wilprise pipeline is a FERC-regulated, approximately 30 -mile NGL pipeline that originates at the Kenner Junction and terminates  in Sorrento, Louisiana,
where volumes flow via pipeline to a Baton Rouge fractionator.

On April 27, 2016, Emerald entered into a second purchase and sale agreement for the purchase of 66.7% of the issued and outstanding membership interests of
Okeanos,  in  exchange  for  a  cash  purchase  price  of  approximately  $27.4  million  (such  transaction,  together  with  the  Pipeline  Transaction,  the  “Emerald
Transactions”). The Okeanos pipeline is a 100 -mile natural gas gathering system located in the Gulf of Mexico with a total capacity of 1.0 Bcf/d. The Okeanos
pipeline  connects  two  platforms  and  one  lateral,  terminating  at  the  Destin  Main  Pass  260  platform  in  the  Mississippi  Canyon  region  of  the  Gulf  of  Mexico.
Contracted volumes on the Okeanos pipeline are based on life-of-field dedication. We became the operator of the Okeanos pipeline on November 1, 2016.

The Partnership funded the aggregate purchase price for the Emerald Transactions with the issuance of 8,571,429 Series C convertible preferred units (the “Series
C Units”) representing limited partnership interests in the Partnership and a warrant (the “Series C Warrant”) to purchase up to 800,000 common units representing
limited partnership interests in the Partnership (“common units”) at an exercise price of $7.25 per common unit amounting to a combined value of approximately
$120.0 million , plus additional borrowings of $91.0 million under our Credit Agreement. ArcLight affiliates hold and participate in distributions on our Series C
Units with such distributions being made in paid-in-kind Series C Units, cash or a combination thereof at the election of the Board of Directors of our General
Partner and upon the consent of the holders of the Series C Units. Our share of earnings of the entities  underlying the Emerald  Transactions  is included  in the
Liquid Pipelines and Services segment gross margin.

Because  our  interests  in  the  entities  underlying  the  Emerald  Transactions  were  previously  owned  by  an  ArcLight  affiliate,  we  recorded  our  investments  at  the
affiliate’s  historical  cost  basis  of  $212.0  million  ,  in  Investment  in  unconsolidated  affiliates  in  our  consolidated  balance  sheets,  and  as  an  investing  activity  of
$100.9 million within the consolidated statements of cash flows. The amount by which the affiliate's historical basis exceeded total consideration paid was $1.0
million  and  is  recorded  as  a  contribution  from  our  General  Partner  in  the  consolidated  statements  of  changes  in  equity,  partners’  capital  and  noncontrolling
interests.

On  October  27,  2017,  American  Midstream  Emerald,  LLC,    a  wholly-owned  subsidiary  of  the  Partnership,  entered  into  a  Purchase  and  Sale  Agreement  with
Emerald Midstream, LLC, an ArcLight affiliate, to purchase an additional 17.0% equity interest in Destin for total consideration of $30.0 million .  As our  17%
 interest in Destin was previously owned directly by ArcLight, we have accounted for our investment at our affiliate's carry-over basis resulting in  $30.3 million
 recorded in  Investments in unconsolidated affiliates in our consolidated balance sheets, and $30.0 million as an investing activity within the related consolidated
statement of cash flows. The amount by which the total consideration was below the carry-over basis was  $0.3 million and was recorded as a contribution from
our general partner within the consolidated statement of changes in equity, partners’ capital and noncontrolling

F-18

interests  and  a  non-cash  financing  activity  in  Note  22  -  Supplemental Cash flow information for  the  year  ended  December  31,  2017.  With  the  acquisition,  the
Partnership now owns a 66.7% interest in Destin.

As Destin continues to be a variable interest entity ("VIE"), the Partnership applied the guidance in ASC 810 - Consolidation to determine if either member has a
controlling financial interest and if the Partnership is the primary beneficiary. As a result of our analysis, neither party has a controlling financial interest nor is the
Partnership the primary beneficiary, and so the Partnership should not consolidate Destin. As it is not appropriate for the Partnership to consolidate Destin under
the VIE model, we revisited the analysis in ASC 323 Investments-Equity Method and Joint Ventures , to determine the appropriate accounting for our interests and
concluded that the Partnership should continue to account for Destin using the equity method of accounting as it continues to have the ability to exert significant
influence over Destin's operations.

Gulf of Mexico Pipeline

On April 15, 2016, American Panther LLC, ("American Panther"), a 60% -owned subsidiary of the Partnership, acquired approximately 200 miles of crude oil,
natural gas, and salt water onshore and offshore Gulf of Mexico pipelines (“Gulf of Mexico Pipeline”) from Chevron Pipeline Company and Chevron Midstream
Pipeline, LLC for approximately $2.7 million in cash and the assumption of certain asset retirement obligations.

The  Partnership  controls  American  Panther  and  therefore  consolidates  it  for  financial  reporting  purposes.  The  American  Panther  acquisition  was  accounted  for
using the acquisition method of accounting and as a result, the purchase price was allocated to the assets acquired and liabilities assumed based on their respective
estimated  fair  values  as  of  the  acquisition  date.  The  purchase  price  allocation  included  $16.6  million  in  pipelines,  $0.4  million  in  land,  $14.3  million  in asset
retirement obligations, and $1.8 million in noncontrolling interests.

American  Panther  contributed  revenue  of  $13.2  million  and  operating  income  of  $7.4  million  to  the  Partnership  for  the  year  ended  December  31,  2016.  Such
amounts  are  included  in  the  Partnership’s  Offshore  Pipelines  and  Services  segment.  During  the  year  ended  December  31,  2016,  the  Partnership  incurred  $0.3
million of transaction costs related to the American Panther acquisition which are included in Corporate expenses in our consolidated statement of operations for
2016.

Unaudited pro forma financial information depicting what the Partnership's revenue, net income and per unit amounts would have been had the American Panther
acquisition occurred on January 1, 2016, is not available because Chevron Pipeline Company and Chevron Midstream Pipeline, LLC did not historically operate
the acquired assets as a standalone business.

Southern Propane Inc.

On May 8, 2015, we acquired substantially all of the assets of Southern Propane Inc. (“Southern”), a Houston-based industrial and commercial propane distribution
and logistics company. The acquisition expanded the asset base and market share of our Propane Marketing Services segment, specifically the acceleration of our
entry into the Houston, Texas market, as well as expansion of our industrial, non-seasonal customers. The total purchase price of $16.3 million consisted of a $12.5
million cash payment that was paid on the acquisition date, and which was funded through the use of borrowings under our Credit Agreement, a $0.1 million cash
payment to the seller as the final working capital adjustment, the issuance of 266,951 common units valued at $3.4 million and a contingent earn-out liability with
an acquisition date fair value of $0.3 million . The gross profit targets were not achieved and the remaining $0.2 million liability was released to income in 2016.

The $16.3 million purchase price was allocated to customer relationship intangible assets of $6.2 million , goodwill of $5.8 million , property, plant and equipment
of $3.0 million , accounts receivable of $1.0 million and other intangible assets of $0.3 million . Goodwill associated with the acquisition principally results from
synergies expected from integrated operations. The fair values of the acquired intangible assets were estimated by applying the income approach which is based on
significant  inputs  that  are  not  observable  in  the  market  and  represents  a  Level  3  measurement.  The  customer  relationship  assets  are  being  amortized  over  a
weighted average useful life of 12 years . The Southern acquisition is part of the Propane Business that was sold in September 2017, see Note 4 - Discontinued
Operations , for additional information regarding the sale of the Propane Business.

JP Energy Partners LP

On March 8, 2017, the Partnership completed the acquisition of JPE, an entity controlled by ArcLight affiliates, in a unit-for-unit exchange. In connection with the
transaction, each JPE common or subordinated unit held by investors not affiliated with ArcLight was converted into the right to receive 0.5775 of a Partnership
common unit, and each JPE common or subordinated unit held by ArcLight affiliates was converted into the right to receive 0.5225 of a Partnership common unit.
The Partnership issued a total of 20.2 million of its common units to complete the acquisition, including 9.8 million common units to ArcLight affiliates.

F-19

As both the Partnership and JPE were controlled by ArcLight affiliates, the acquisition represented a transaction among entities under common control. Although
the Partnership was the legal acquirer, JPE was considered the acquirer for accounting purposes as ArcLight obtained control of JPE on April 15, 2013 before it
obtained control of the Partnership. In addition, the accompanying consolidated financial statements and related notes of past periods have been retrospectively
adjusted to include the historical results of JPE prior to the effective date of the JPE Merger. The accompanying consolidated financial statements and related notes
present the combined financial position, results of operations, cash flows and equity of JPE at historical cost.

Viosca Knoll Gathering System

On June 2, 2017, we acquired  100%  of VKGS from Genesis Energy, L.P. for total consideration of approximately  $32.0 million  in cash and have accounted for
this acquisition  as a business combination.  VKGS serves producing fields located  in the Main Pass, Mississippi Canyon and Viosca Knoll areas of the Gulf of
Mexico and connects to several major delivery pipelines including the Partnership’s High Point and Destin pipelines. VKGS will provide greater East-West Gulf
connectivity, through the connection of the High Point Gas Transmission system and the Destin Pipeline, both operated by us. The VKGS acquisition was funded
with the borrowings under our Credit Agreement, and VKGS was added to our Offshore Pipelines and Services segment.

The following table presents our aggregated allocation of the purchase price based on fair values of assets and liabilities acquired at the date of acquisition, June 2,
2017 (in thousands):

Panther

On August 8, 2017, the Partnership acquired  100%  of the interest in POGS, PPL and POC from Panther for approximately  $60.9 million . The consideration
included  $39.1 million  cash, funded from borrowings under the Partnership’s Credit Agreement, and common units representing limited partner interests in the
Partnership, valued at  $12.5 million  based on unit value as of the acquisition date. Panther owns and operates more than   1,000  miles of oil and gas pipelines,
primarily  in Texas and Louisiana  offshore  state  and federal  waters. The underlying  acquired  assets  are  highly complementary  to the  Partnership’s  core Gulf of
Mexico assets as a substantial portion of Panther’s cash flows are generated by our joint ventures.

As part of the purchase of POGS, we acquired the outstanding interests in one of our equity investments, MPOG, as well as the remaining equity interest in our
consolidated subsidiary, AmPan. As such, the Partnership now owns  100%  of MPOG and AmPan. We determined that the acquisition of the remaining interest in
MPOG on August 8, 2017 resulted in a change in control and MPOG has been consolidated from the acquisition date. The effect was the Partnership’s previously
held  equity  interest  in  MPOG  was  remeasured  to  fair  value  and  the  excess  (approximately    $36.0  million  )  of  fair  value  over  historical  carrying  value  was
recognized as a gain in Other income on the consolidated statement of operations for the year ended December 31, 2017.

For  AmPan,  which  has  historically  been  consolidated  by  the  Partnership,  the  acquisition  of  Panther’s  remaining  interest  resulted  in  the  acquisition  of  a
noncontrolling interest. Accordingly, the excess of the fair value of the acquired interest of $28.6 million over the carrying value of the noncontrolling interest
(approximately  $4.6 million ) has been reported as a reduction to general partner and limited partner interests. PPL owns a  50%  undivided ownership interest in
the Matagorda and the Brazoria County Gas systems which will be proportionally consolidated from the acquisition date. POC operates pipeline assets on behalf of
both third parties and affiliates of the Partnership for a fee and will be fully consolidated by the Partnership.

the date of acquisition, August 8, 2017 (in thousands):

Acquisition of Trans-Union pipeline

On  November  3,  2017,  we completed  the  acquisition  of  100% of  the  equity  interests  in  Trans-Union  Interstate  Pipeline,  LP  (“Trans-Union”)  from  affiliates  of
ArcLight, for a total consideration of approximately $49.4 million . The consideration consisted of approximately $16.9 million in cash funded from borrowings
under our Credit Agreement and the assumption of the remaining balance of $32.5 million non-recourse debt with 3.97% interest, quarterly payments and maturity
date on December 31, 2032. See Note 14 - Debt Obligations for more information. Trans-Union owns a 42-mile, 30-inch diameter high-pressure FERC-regulated
natural  gas  interstate  pipeline  with  546,000 MMbtu/day  of  maximum  capacity.  As  a  result,  the  results  of  these  operations  will  be  reported  in  our  Natural  Gas
Transportation Services segment. See Note 23 - Reportable Segments. As the transaction represents an asset acquisition among entities under common control, as
defined by ASU No. 2017-01 , “Business Combinations (Topic 805): Clarifying the Definition of a Business”, we did not have to recast our historical financial
statements  to  reflect  the  accounts  of  Trans-Union  from  the  date  ArcLight  obtained  control.  Instead,  we  recorded  the  acquired  assets  at  carry  over  basis  or
ArcLight's historical cost.

4. Discontinued Operations

Propane Business

On September 1, 2017, the Partnership completed the disposition of the Propane Business pursuant to the Membership Interest Purchase Agreement dated July 21,
2017, between AMID Merger LP, a wholly owned subsidiary of the Partnership, and SHV Energy N.V. Through the transaction, we divested Pinnacle Propane’s
40 service  locations;  Pinnacle  Propane  Express’  cylinder  exchange  business  and related  logistic  assets;  and the Alliant  Gas utility  system.  Prior to the sale,  we
moved the trucking business from the Propane Business segment to the Liquid Pipelines and Services segment. With the disposition of the Propane Business, we
eliminated the Propane Marketing Services segment.

In connection with the transaction, the Partnership received approximately $170.0 million in cash, net of customary closing adjustments. We recorded a gain of
$47.4 million , net of $2.5 million of transaction costs, which is included in (Gains) losses on sale of assets and business line item on the Partnership's consolidated
statement of cash flows for the year ended December 31, 2017. The Partnership has reported the accounts and the results of our Propane Business as discontinued
operations in our consolidated statements of operations.

On February 1, 2016, we sold certain trucking and marketing assets in the Mid-Continent area (the “Mid-Continent Business”) to JP Development for $9.7 million
in cash. We recognized a loss on the disposal of approximately $12.9 million during the year ended December 31, 2015, which primarily related to goodwill and
long-lived asset impairment charges. Prior to the classification as discontinued operations, we reported the Mid-Continent Business in our Liquid Pipelines and
Services segment.

5. Concentration of Credit Risk

Significant customers are defined as those who represent 10% of more of our consolidated revenue during the year. In 2017, we had two such customers which
accounted for 23% and 13% , respectively,  of our consolidated revenue, Occidental Petroleum Corporation ("Occidental") and Royal Dutch Shell. The revenue
from Occidental is reported in our Liquid Pipelines and Services and Terminalling Services segments. The revenue from Shell is reported in our Gas Gathering and
Processing Services, Liquid Pipelines and Services, Offshore Pipelines and Services and Terminalling Services segments.

In 2016, we had two customers which accounted for 21% and 13% , respectively, of our consolidated revenue, Occidental and Plains All American Pipeline, L.P.
In 2015, we had one such customer, Occidental, which accounted for 34% of our consolidated revenue.

We are party to various commercial netting agreements that allow us and contractual counterparties to net receivable and payable obligations. These agreements
are customary and the terms follow standard industry practice. In the opinion of management, these agreements reduce the overall counterparty risk exposure.

To  limit  the  effect  of  commodity  price  changes  and  maintain  our  cash  flow  and  the  economics  of  our  development  plans,  we  enter  into  commodity  derivative
contracts  from  time  to  time.  The  terms  of  the  contracts  depend  on  various  factors,  including  management's  view  of  future  commodity  prices,  economics  on
purchased  assets  and  future  financial  commitments.  This  hedging  program  is  designed  to  mitigate  the  effect  of  commodity  price  declines  while  allowing  us  to
participate to some extent in commodity price increases. Management regularly monitors the commodity markets and our financial commitments to determine if,
when, and at what level commodity hedging is appropriate in accordance with policies that are established by the board of directors of our General Partner.

To  meet  this  objective,  we  use  a  combination  of  fixed  price  swaps,  basis  swaps  and  forward  contracts.  We  enter  into  commodity  contracts  with  multiple
counterparties, and in some cases, may be required to post collateral with our counterparties in connection with our derivative positions. The counterparties are not
required to post collateral with us in connection with their derivative positions. Netting agreements are in place that permit us to offset our commodity derivative
asset and liability positions with our counterparties. At times, we may also terminate or unwind hedges or portions of hedges in order to meet cash flow objectives
or when the expected  future  volumes  do not support the level  of hedges. Our forward  contracts  that  qualify  for the  normal  purchase  normal  sale  exception  are
recognized when the underlying physical transaction is delivered. While these contracts are considered derivative financial instruments, they are not recorded at
fair  value,  but  on  an  accrual  basis  of  accounting.  If  it  is  determined  that  a  transaction  no  longer  meets  the  exception,  the  fair  value  of  the  related  contract  is
recorded on the consolidated balance sheets and immediately recognized through earnings.

The following table summarizes the net notional volume buy (sell) of our outstanding commodity-related derivatives, excluding those derivatives that qualified for
the normal purchase normal sale exception as of December 31, 2017 and 2016, none of which were designated as hedges for accounting purposes.

To manage the impact of the interest rate risk associated with our Credit Agreement, we enter into interest rate swaps from time to time, effectively converting a
portion of the cash flows related to our long-term variable rate debt into fixed rate cash flows.

As of December 31, 2017 and 2016, we had a combined notional principal amount of  $550.0 million and $650.0 million , respectively, of variable to fixed interest
rate swap agreements. As of December 31, 2017, the maximum length of time over which we have hedged a portion of our exposure due to interest rate risk was
through December 31, 2022.

The fair value of our interest rate swaps was estimated using a valuation methodology based upon forward interest rates and volatility curves as well as other
relevant economic measures, if necessary. Discount factors may be utilized to extrapolate a forecast of future cash flows associated with long dated transactions or
illiquid market points. The inputs, which represent Level 2 inputs in the valuation hierarchy, are obtained from independent pricing services and we have made no
adjustments to those prices.

Weather Derivative

In the second quarters of 2017 and 2016, we entered into weather derivatives to mitigate the impact of potential unfavorable weather to our operations under which
we could receive  payments  totaling  up to  $30.0 million in the  event  that  a hurricane  or hurricanes  of certain  strength  pass through the area  as identified  in the
related agreement. The weather derivatives, which are accounted for using the intrinsic value method, were entered into with a single counterparty and we were not
required to post collateral.

We paid premiums of $1.1 million and $1.0 million in 2017 and 2016, respectively, which are amortized to Direct operating expenses on a straight-line basis over
the 1 year term of the contract. Unamortized amounts associated with weather derivatives were approximately $0.5 million and $ 0.4 million at December 31, 2017
and December 31, 2016 , respectively, and are included in Other current assets on the consolidated balance sheets.

At December 31, 2017 and 2016 , gross property, plant and equipment included $367.6 million and $291.1 million , respectively, related to our FERC regulated
interstate and intrastate assets.

Depreciation  expense  totaled  $76.9 million , $69.7 million and $60.6 million for the years ended December  31, 2017  , 2016 and 2015 ,  respectively,  which  is
included in Depreciation, amortization and accretion expense in the consolidated statements of operations. Depreciation expense amounts have been adjusted by
$8.1 million , $13.2 million , and $15.5 million for  the  years  ended  December  31,  2017,  2016  and  2015,  respectively,  to  present  the  impact  of  classifying  the
Propane Business and Mid-Continent's operations as discontinued operations, with the Propane Business being divested in September 2017 and Mid-Continent's
operations being divested in February 2016. Capitalized interest was $2.5 million , $2.7 million and $1.9 million for the years ended December 31, 2017 , 2016 and
2015 , respectively.

Impairment

During the fourth quarter of 2017, we identified certain assets where events or circumstances indicated we may not recover their carrying value. Due to plant shut
downs  in  the  quarter  and  changes  in  our  forecast  volumes  on  certain  assets  as  part  of  our  annual  budget  process,  we  made  decisions  that  impact  our  ability  to
recover the carrying value of assets. Accordingly, we have impaired our Yellow Rose, Bazor Chatom, Burns Point and Transtar assets in our Gas Gathering and
Processing  Services  segment,  COSL  in  our  Liquid  Pipeline  and  Services  segment  and  Trigas  in  our  Natural  Gas  Transportation  services  segment.  The  total
impairment charge was $103.9 million related to our property, plant and equipment. The impairment consisted of $97.8 million related to our Gas Gathering and
Processing Services segment, $3.9 million related to our Natural Gas Transportation Services segment and $2.2 million related to our Liquid Pipelines and Services
segment.  Our  fair  value  measurements  related  to  these  assets  are  based  on  significant  inputs  not  observable  in  the  market  and  thus  represent  a  Level  3
measurement.

There were no impairments in 2015 and an impairment of $0.7 million was recorded in 2016.

10. Goodwill and Intangible Assets, Net

Goodwill

Overview

Under the Step Zero approach, we look to qualitative factors to determine if it is “more-likely-than not” the fair value of the reporting unit is less than its carrying
value.  If  based  upon  the  qualitative  review,  we  determine  that  it  is  more-likely-than  not  that  the  fair  value  is  in  excess  of  its  carrying  value,  then  there  is  no
requirement to perform additional steps. If we determine it is "more-likely than not" the fair value is less than the carrying value, we move to Step One, where we
compare the fair value of a reporting unit to its carrying amount , including goodwill. If the fair value of the reporting unit exceeds its carrying amount, goodwill

F-29

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
associated with the reporting unit ("RU") is not considered impaired, and no further review is required. If the fair value of the RU is less than the carrying amount,
the goodwill impairment is calculated as the difference between the RU’s fair value and carrying amount, not to exceed the carrying amount of the goodwill. The
fair value is estimated using the income approach based on significant inputs not observable in the market and thus represent a Level 3 measurement.

2015 Impairment

In 2015, as a result of our Step One analysis in the fourth quarter, we determined that the estimated fair value of certain reporting units within our Gas Gathering
and Processing Services reportable segment and Liquid Pipelines and Services reportable segment were less than their respective carrying amounts, primarily due
to  changes  in  assumptions  related  to  commodity  prices,  the  timing  of  estimated  drilling  by  producers,  and  discount  rates.  These  assumptions  were  adversely
impacted by the continuing decline in market conditions within the energy sector at the time. Step Two of the goodwill impairment test involved allocating the
estimated  fair  value  of  each  reporting  unit  among  the  assets  and  liabilities  of  the  reporting  unit  in  a  hypothetical  purchase  price  allocation.  The  results  of  the
hypothetical purchase price allocation indicated there was no fair value attributable to goodwill of the reporting units within our Gas Gathering and Processing
Services reportable segment and we recognized an impairment charge of $118.6 million which consisted of $95.0 million and $23.6 million related to the Costar
and Lavaca systems, respectively. In addition, we recognized a $29.9 million impairment charge in our Liquid Pipelines and Services reportable segment relating
to our COSL business and JP Liquids. As a result, we recognized total goodwill impairment charges of  $148.5 million  during the year ended December 31, 2015.

2016 Impairment

In  the  fourth  quarter  of  2016,  we recognized  additional  goodwill impairment  charges  totaling  $2.7 million related  to our JP Liquids businesses reported  in our
Liquid Pipelines and Services reportable segment as a result of our Step Two goodwill impairment analysis. We also recorded a goodwill impairment charge of
$12.8 million in 2016 related to our Pinnacle Propane Express business that we disposed, which is reported in Net loss from discontinued operations in the 2016
consolidated statement of operations.

2017 Impairment

In 2017, as a result of our annual Step One analysis in the fourth quarter, we identified that the fair value of our Silver Dollar and COSL reporting units, which are
both in our Liquid Pipelines and Services segment, exceeded their carrying values. Accordingly, we recorded an impairment charge of $78.0 million , of which
$61.4 million is related to Silver Dollar and $16.6 million is related to COSL.

In  2015,  prior  to  the  sale  of  the  Mid-Continent  Business  on  February  1,  2016,  we  recorded  an  intangible  asset  impairment  charge  of  $0.7  million  related to
customer relationships, which was included in Income (loss) from discontinued operations line item in the consolidated statement of operations of such year.

During the fourth quarter of 2017, we identified certain assets where events or circumstances indicated we may not recover their carrying value. Accordingly, we
recorded impairment charges of $10.8 million associated with the dedicated acreage related to our Yellow Rose asset in our Gas Gathering and Processing segment
and $1.9 million associated with customer relationships related to our COSL asset in our Liquid Pipelines and Services segment. The charges are reported as a
component of Impairment of long-lived assets / intangible assets line item in the consolidated statement of operations for the year ended December 31, 2017. Our
fair value measurements related to these assets are based on significant inputs not observable in the market and thus represent a Level 3 measurement.

For the years ended December 31, 2017 , 2016 and 2015 , amortization expense on our intangible assets was $24.3 million , $19.2 million and $20.0 million ,
respectively, which is included depreciation, amortization and accretion in the consolidated statements of operations. Amortization expense of $1.7 million , $2.9
million and $4.0 million for the years ended December 31, 2017, 2016 and 2015, respectively, relates to the sale of the Propane Business in 2017, Mid-Continent
Business and Propane Business in 2016 and Mid-Continent Business and Propane Business in 2015, respectively, and is included in Net loss from discontinued
operations, net of tax line item in the consolidated statement of operations.

Estimated amortization expense for each of the next five years ranges from $13.3 million to $14.9 million , with an aggregate $118.6 million to be recognized in
subsequent years.

The  storage  tank  capacity  in  our  crude  oil  storage  facility  in  Cushing,  Oklahoma  is  dedicated  to  one  customer  pursuant  to  a  long-term  contract  with  an  initial
expiration  date  of  August  3,  2017  and  an  optional  two -year  renewal  term.  We  did  not  receive  a  notice  of  the  customer's  intent  to  renew  this  contract  by  the
required date of February 3, 2017 and therefore we have accelerated the remaining amortization of the related customer relationship intangible of approximately
$9.9 million over the remaining term of the contract, which expired on August 3, 2017.

Joint Venture with Targa Midstream Services, LLC

On  August  8,  2017,  we  entered  into  a  new  joint  venture  agreement  with  Targa  Midstream  Services,  LLC  (“Targa”)  by  which  our  previously  wholly  owned
subsidiary Cayenne Pipeline, LLC (“Cayenne”) became the Cayenne joint venture between Targa and

F-31

 
 
 
 
 
 
 
 
 
 
 
 
us (“Cayenne JV”). We received  $5.0 million  in cash in exchange for the sale of  50%  ownership interest in Cayenne to Targa. The sole asset of the joint venture
is  a  natural  gas  pipeline  which  was  converted  into  a  NGL pipeline.  Both  parties  will  each  have    50%  economic interests and   50%  voting  rights,  with  Targa
serving as the operator of the pipeline and the joint venture. The additional costs of conversion and associated construction are shared equally by us and Targa. On
December 28, 2017, the pipeline became operational. The gain recognized associated with this joint venture is included in the (Gains) losses on sales of assets and
business line item on the consolidated statement of cash flows for the year ended December 31, 2017.

On a annual basis, we review our ARO liabilities. There are certain cases when there is insufficient information to reasonably determine the timing and/or method
of  settlement  for  purposes  of  estimating  the  fair  value  of  the  asset  retirement  obligation.  In  such  cases,  the  asset  retirement  obligation  cost  is  considered
indeterminate because there is no data or information that can be derived from past practice, industry practice, management's experience, or the asset's estimated
economic life. The useful lives of most pipeline systems are primarily derived from available supply resources and ultimate consumption of those resources by end
users. Variables can affect the remaining lives of the assets which preclude us from making a reasonable estimate of the asset retirement obligation. Indeterminate
asset  retirement  obligation  costs  will  be  recognized  in  the  period  in  which  sufficient  information  exists  to  reasonably  estimate  potential  settlement  dates  and
methods.

(1) Includes $14.3 million assumed in connection with the Gulf of Mexico Pipeline acquisition in 2016 and $8.7 million assumed in connection with the Panther
acquisition on August 8, 2017 described in Note 3 - Acquisitions . This assumed ARO in 2017 was associated with PPL, POGS and MPOG entities. Of the balance,
the total ARO associated with MPOG was approximately $7.0 million . This balance represents 100% of the ARO balance associated with MPOG that we assumed
as a result of purchasing the remaining 33.3% of ownership of MPOG, which was our 66.7% investment pre-August 8, 2017.

(2) Represents updated liability associated with the ARO relating to our High Point assets in the Offshore Pipelines and Services segment. This update was due to
our annual review of ARO obligations which resulted in a revised estimated cost of the original ARO recorded.

We may be required to establish security against potential ARO relating to the abandonment of certain transmission assets that may be imposed on the previous
owner  by  applicable  regulatory  authorities.  We  have  deposited  $5.0  million  with  a  third  party  to  secure  our  performance  on  these  potential  obligations.  These
deposits are included in Restricted cash, long-term in our consolidated balance sheets as of December 31, 2017 and 2016 .

AMID Revolving Credit Agreement

On March 8, 2017, the Partnership along with other subsidiaries of the Partnership (collectively, the “Borrowers”) entered into the Second Amended and Restated
Credit Agreement, with Bank of America N.A., as Administrative Agent, Collateral Agent and L/C Issuer, Wells Fargo Bank, National Association, as Syndication
Agent, and other lenders or Credit Agreement, which increased the Borrowers’ borrowing capacity thereunder from $750.0 million to $900.0 million and provided
for an accordion feature that will permit, subject to customary conditions, the borrowing capacity under the facility to be increased to a maximum of $1.1 billion .
The $900 million in lending commitments under the Credit Agreement includes a $30 million sublimit for borrowings by Blackwater Investments, Inc. and a $100
million sublimit for letters of credit. The Credit Agreement matures on September 5, 2019. All obligations under the Credit Agreement and the guarantees of those
obligations are secured, subject to certain exceptions, by a first-priority lien on and security interest in (i) substantially all of the Borrowers’ assets and the assets of
certain of the subsidiaries of the Partnership and (ii) the capital stock of certain of the Partnership’s subsidiaries.

We can elect to have loans under our Credit Agreement bear interest either at (a) a Eurodollar-based rate, plus a margin ranging from 2.00% to 3.25% depending
on our total leverage ratio then in effect, or (b) a base rate which is a fluctuating rate per annum equal to the highest of (i) the Federal Funds Rate plus 0.50% ,
(ii) the rate of interest in effect for such day as publicly announced from time to time by Bank of America as its "prime rate," and (iii) a Eurodollar-based rate plus
1.00% , in each case of clause (i)-(iii), plus a margin ranging from 1.00% to 2.25% depending on the total leverage ratio then in effect. We also pay a commitment
fee ranging from 0.375% to 0.50%  per annum, depending on our total leverage ratio then in effect, on the undrawn portion of the revolving loan under the Credit
Agreement.

The guarantees by the Guarantors are full and unconditional and joint and several among the Guarantors. The terms of the Credit Agreement include covenants that
restrict our ability to make cash distributions and acquisitions in some circumstances. The remaining principal balance and any accrued and unpaid interest will be
due and payable in full at maturity, on September 5, 2019.

The Credit Agreement contains certain financial covenants that are applicable as of the end of any fiscal quarter, including a consolidated total leverage ratio which
requires our indebtedness not to exceed 5.00 times adjusted consolidated EBITDA (provided that the minimum consolidated total leverage may be increased to
5.50 times adjusted consolidated EBITDA in connection with the closing of certain material acquisitions as of the end of the quarter during which such acquisition
closes, and as of the end of the subsequent two quarters), a consolidated secured leverage ratio which requires our secured indebtedness not to exceed 3.50 times
adjusted consolidated EBITDA, and a minimum interest coverage ratio that requires our adjusted consolidated EBITDA to exceed consolidated interest charges by
not less than 2.50 times. Regarding the total leverage ratio, in the first three quarters of 2017, we were in compliance with the covenants requirements ratios of 5.50
times, 5.50 times and 5.00 times, for quarter periods ended March 31, 2017, June 30, 2017 and September 30, 2017, respectively, as described above. During the
fourth quarter of 2017, we elected to be in a Specified Acquisition Period, as defined in Section 7.19 Financial Covenants of the Credit Agreement, which enables
us to use a ratio of 5.50 times for the fourth quarter of 2017 as well as the first and second quarters of 2018.

As of December 31, 2017 , our consolidated total leverage ratio was 5.23 , our consolidated secured leverage ratio was 3.29 , and our interest coverage ratio was
3.62 , which were all in compliance with the related covenants of our Credit Agreement. At December 31, 2017 and 2016 , letters of credit outstanding under the
Credit Agreement were $24.1 million and $7.4 million , respectively. As of December 31, 2017, we had approximately $697.9 million of borrowings outstanding.

The carrying value of amounts outstanding under the Credit Agreement approximates the related fair value, as interest charges vary with market rates conditions.
For the years ended December 31, 2017, 2016 and 2015, the weighted average interest rate on borrowings under our Credit Agreement was approximately 4.96% ,
4.29% , and 3.67% , respectively.

Our ability  to maintain  compliance  with the leverage  and interest  coverage  ratios included in the Credit Agreement  may be subject to, among other things, the
timing and success of initiatives we are pursuing, which may include expansion capital projects, acquisitions or drop down transactions, as well as the associated
financing for such initiatives. The terms of the Credit Agreement also include covenants that restrict our ability to make cash distributions and acquisitions in some
circumstances.  If  required,  ArcLight  ,  which  controls  the  General  Partner  of  the  Partnership,  has  confirmed  its  intent  to  provide  financial  support  for  the
Partnership to maintain compliance with the covenants contained in the Credit Agreement through April 10, 2019.

We use the term “revolving credit facility” or “Credit Agreement,” to refer to our First Amended and Restated Credit Facility and to our Second Amended and
Restated Credit Facility, as the context may require.

JPE Credit Agreement

On  February  12,  2014,  we  entered  into  the  JPE  Credit  Agreement  with  Bank  of  America,  N.A,  which  was  available  for  refinancing  and  repayment  of  certain
existing indebtedness, working capital, capital expenditures, permitted acquisitions and other general partnership purposes. The JPE Credit Agreement consisted of
a $275.0 million revolving loan, which included a sub-limit of up to $100.0 million for letters of credit.

Borrowings under the JPE Credit Agreement bore interest at a rate per annum equal to, at our option, either (a) a base rate determined by reference to the highest of
(1) the federal funds effective rate plus 0.5% , (2) the prime rate of Bank of America, and (3) LIBOR, subject to certain adjustments, plus 1.00% or (b) LIBOR, in
each case plus an applicable rate. The applicable rate was (a) 1.25% for prime rate borrowing and 2.25% for LIBOR borrowings. The commitment fee was subject
to an adjustment each quarter based in the Consolidated Net Total Leverage Ratio, as defined in the related agreement. The carrying value of amounts outstanding
under the JPE Credit Agreement approximates the related fair value, as interest charges vary with market rate conditions.

The JPE Credit Agreement was scheduled to mature on February 12, 2019, but was paid off and terminated on March 8, 2017 in connection with the Partnership's
acquisition of JPE.

8.50% Senior Notes

On  December  28,  2016,  the  Partnership  and  American  Midstream  Finance  Corporation,  our  wholly-owned  subsidiary  (the  “Co-Issuer”  and  together  with  the
Partnership, the “Issuers”), completed the issuance and sale of $300 million aggregate principal amount of their 8.50% Senior Notes due 2021 (the "8.50% Senior
Notes"). The 8.50% Senior Notes are jointly and severally guaranteed by certain of the Partnership's subsidiaries. The 8.50% Senior Notes rank equal in right of
payment with all existing and future senior indebtedness of the Issuers, and senior in right of payment to any future subordinated indebtedness of the Issuers. The
8.50% Senior Notes were issued at par and provided approximately $294.0 million in proceeds, after deducting the initial purchasers' discount of $6.0 million . The
Partnership also incurred $2.7 million of direct issuance costs resulting in net proceeds related to the 8.50% Senior Notes of $291.3 million .

Upon the closing of the JPE Merger and the satisfaction of other conditions related thereto, the restricted cash was released from escrow and was used to repay the
JPE Credit Facility and to reduce borrowings under the Partnership’s Credit Agreement.

On  December  19,  2017,  the  Issuers  completed  the  issuance  and  sale  of  an  additional  $125  million  in  aggregate  principal  amount  of  8.50% Senior  Notes  (the
“Additional Issuance”), net of issuance cost of approximately $3.0 million .

The Additional Issuance will mature on December 15, 2021 and interest on the Additional Issuance will accrue from December 15, 2017. Interest on the Additional
Issuance  is  payable  in  cash  semiannually  in  arrears  on  each  June  15  and  December  15,  with  interest  payable  on  the  Additional  Issuance  commencing  June  15,
2018. Interest will be payable to holders of record on the June 1 and December 1 immediately preceding the related interest payment date, and will be computed on
the basis of a 360-day year consisting of twelve 30-day months. Pursuant to the registration rights agreements entered into in connection with the issuances of the
8.50% Senior Notes, additional interest on the 8.50% Senior Notes accrues at 0.25% per annum for the first 90-day period following December 23, 2017 and by an
additional 0.25% per annum with respect to each subsequent 90-day period, up to a maximum additional rate of 1.00% per annum over 8.50%, until we complete
an exchange offer for the 8.50% Senior Notes.

F-36

 
At any time prior to December 15, 2018, the Issuers may redeem up to 35% of the aggregate principal amount of 8.50% Senior Notes, at a redemption price of
108.50% of the principal amount, plus accrued and unpaid interest to the redemption  date, in an amount not greater than the net cash proceeds of one or more
equity offerings by the Partnership, provided that:

•

•

at  least  65% of  the  aggregate  principal  amount  of  the  8.50% Senior  Notes  remains  outstanding  immediately  after  such  redemption  (excluding  8.50%
Senior Notes held by the Partnership and its subsidiaries); and

the redemption occurs within 180 days of the closing of each such equity offering.

On and after December 15, 2018, the Issuers may redeem all or a part of the 8.50% Senior Notes, at the redemption prices (expressed as percentages of principal
amount) set forth below, plus accrued and unpaid interest, if redeemed during the twelve-month period beginning on December 15 of the years indicated below:

The  Indenture  restricts  the  Partnership’s  ability  and  the  ability  of  certain  of  its  subsidiaries  to,  among  other  things:  (i)  incur,  assume  or  guarantee  additional
indebtedness,  issue any disqualified  stock  or issue preferred  units, (ii) create  liens  to secure  indebtedness,  (iii)  pay distributions  on equity  securities,  redeem  or
repurchase equity securities or redeem or repurchase subordinated securities, (iv) make investments, (v) restrict distributions, loans or other asset transfers from
restricted  subsidiaries, (vi) consolidate  with or merge  with or into, or sell substantially  all of its properties  to, another person, (vii) sell or otherwise dispose of
assets, including equity interests in subsidiaries, (viii) enter into transactions with affiliates, (ix) engage in certain business activities and (x) enter into sale and
leaseback  transactions.  These  covenants  are  subject  to  a  number  of  important  exceptions  and  qualifications.  If  at  any  time  the  8.50% Senior  Notes  are  rated
investment grade by either Moody’s Investors Service, Inc. or Standard & Poor’s Ratings Services and no Default or Event of Default (as each are defined in the
Indenture)  has  occurred  and  is  continuing,  many  of  such  covenants  will  terminate  and  the  Partnership  and  its  subsidiaries  will  cease  to  be  subject  to  such
covenants.

The carrying value of the 8.50% Senior Notes as of December 31, 2016 approximates the related fair value as of that date because the Senior Notes were issued on
December 28, 2016. The carrying value of the 8.50% Senior Notes as of December 31, 2017 approximates the fair value as of that date of $437.1 million . This
estimate was based on similar private placement transactions along with changes in market interest rates which represent a Level 2 measurement.

3.77% Senior Notes

On  September  30,  2016,  Midla  Financing,  LLC  ("Midla  Financing"),  American  Midstream  (Midla),  LLC  (“Midla”),  and  MLGT  and  together  with  Midla,  (the
"Note Guarantors") entered into a Note Purchase and Guaranty Agreement with certain institutional investors (the “Purchasers”) whereby Midla Financing issued
$60.0 million in aggregate principal amount of 3.77% Senior Notes due June 30, 2031. Principal and interest on the 3.77% Senior Notes is payable in installments
on the last business day of each quarter beginning June 30, 2017 with the remaining  balance payable  in full on June 30, 2031. The average  quarterly principal
payment is approximately $1.1 million . The 3.77% Senior Notes were issued at par and provided proceeds of approximately $57.7 million , net of debt issuance
costs of $2.3 million .

Net proceeds from the 3.77% Senior Notes are restricted and will be used to fund project costs incurred in connection with the construction of the Midla-Natchez
Line, the retirement of Midla’s existing 1920’s pipeline, the move of our Baton Rouge operations to the MLGT system, and the reconfiguration of the DeSiard
compression system and all related ancillary facilities. These proceeds can also be used to pay costs incurred in connection with the issuance of the 3.77% Senior
Notes, and for general corporate purposes of Midla Financing. As of December 31, 2017 , Restricted cash includes $14.9 million from the issuance of the 3.77%
Senior Notes.

The Note Purchase Agreement includes customary representations and warranties, affirmative and negative covenants (including financial covenants), and events
of default that are customary for a transaction of this type. Midla Financing must maintain a debt service reserve account containing six months of principal and
interest payments, and Midla Financing and the Note Guarantors (including any entities that become guarantors under the terms of the 3.77% Senior Note Purchase
Agreement) are restricted from making distributions until June 30, 2017, unless the debt service coverage ratio is not less than, and is not projected to be for the
following 12 calendar months less than, 1.20 :1.00, and unless certain other requirements are met.

F-37

In connection with the 3.77% Senior Note Purchase Agreement, the Note Guarantors guaranteed the payment in full of all Midla Financing’s related obligations.
Also,  Midla  Financing  and  the  Note  Guarantors  granted  a  security  interest  in  substantially  all  of  their  tangible  and  intangible  personal  assets,  including  the
membership interests in each Note Guarantor held by Midla Financing, and Midla Holdings pledged the membership interests in Midla Financing to the Collateral
Agent.

As of December 31, 2017 and 2016, the fair value of the 3.77% Senior Notes was $53.8 million and $ 54.6 million , respectively. This estimate was based on
similar private placement transactions along with changes in market interest rates which represent a Level 2 measurement.

3.97% Trans-Union Secured Senior Notes

On  May  10,  2016,  Trans-Union  Interstate  Pipeline,  LP  ("Trans-Union")  entered  into  an  agreement  with  certain  institutional  investors  in  the  insurance  business
represented  by  Babson  Capital  Management  LLC  whereby  Trans-Union  issued  $35.0  million  in  aggregate  principal  amount  of  3.97%  Senior  Secured  Notes
("Trans-Union Senior Notes") due December 31, 2032. Principal and interest on the Trans-Union Senior Notes is payable in installments on the last business day of
each quarter beginning June 30, 2016 with the remaining balance payable in full on December 31, 2032. The average quarterly principal payment is approximately
$0.5 million . The Trans-Union Senior Notes were issued at par and provided a net proceeds of approximately $34.6 million after deducting related issuance cost of
approximately $0.4 million . The Partnership assumed the Trans-Union Senior Notes following the Trans-Union acquisition on November 3, 2017. See Note 3 -
Acquisitions . As of December 31, 2017 , the fair value of the 3.97% Senior Notes was approximately $30.2 million . This estimate was based on similar private
placement transactions along with changes in market interest rates which represent a Level 2 measurement.

Affiliates of our General Partner hold and participate in quarterly distributions on our convertible preferred units, with such distributions being made in cash, paid-
in-kind units or a combination thereof, at the election of the Board of Directors of our General Partner, although quarterly distribution on our Series C Units may
be made in cash, paid-in-kind units or a combination thereof, at the election of the Board of Directors of our General Partner and upon the consent of the holders of
the Series C Units. The convertible preferred unitholders have the right to receive cumulative distributions in the same priority and prior to any other distributions
made in respect of any other partnership interests.

To  the  extent  that  any  portion  of  a  quarterly  distribution  on  our  convertible  preferred  units  to  be  paid  in  cash  exceeds  the  amount  of  cash  available  for  such
distribution, the amount of cash available will be paid to our convertible preferred unitholders on a pro rata basis while the difference between the distribution and
the available cash will become arrearages and accrue interest until paid.

Series A-1 Convertible Preferred Units

On April 15, 2013, the Partnership, our General Partner and AIM Midstream Holdings entered into agreements with HPIP, pursuant to which HPIP acquired 90%
of our General Partner and all of our subordinated units from AIM Midstream Holdings and contributed the High Point System and $15.0 million in cash to us in
exchange for 5,142,857 of our Series A-1 Units.

F-38

 
 
 
 
 
 
 
 
 
   
The Series A-1 Units receive distributions prior to distributions to our common unitholders. The distributions on the Series A-1 Units are equal to the greater of
$0.4125 per unit or the declared distribution to common unitholders. The Series A-1 Units may be converted into common units on a one -to-one basis, subject to
customary  anti-dilutive  adjustments,  at the option of the unitholders  on or any time after  January 1, 2014. As of December  31, 2017, the conversion price was
$15.23 .

Upon any liquidation and winding up of the Partnership or the sale of substantially all of its assets, the holders of Series A-1 Units will generally be entitled to
receive, in preference to the holders of any of the Partnership's other equity securities, but in parity with all convertible preferred units, an amount equal to the sum
of $15.23 multiplied by the number of Series A-1 Units owned by such holders, plus all accrued but unpaid distributions on such Series A Units.

Prior to the consummation of any recapitalization, reorganization, consolidation, merger, spin-off or other business combination in which the holders of common
units are to receive securities, cash or other assets (a "Partnership Event"), we are obligated to make an irrevocable written offer, subject to consummation of the
Partnership Event, to each holder of Series A Units to redeem all (but not less than all) of such holder's Series A-1 Units for a per unit price payable in cash as
described in the Partnership Agreement.

Upon receipt  of such  a redemption  offer  from  us, each  holder  of Series  A-1 Units may  elect  to  receive  such cash amount  or a preferred  security  issued by the
person  surviving  or  resulting  from  such  Partnership  Event  and  containing  provisions  substantially  equivalent  to  the  provisions  set  forth  in  the  Partnership
Agreement with respect to the Series A-1 Units without material abridgement.

Except as provided in the Partnership Agreement, the Series A-1 Units have voting rights that are identical to the voting rights of the common units and will vote
with the common units as a single class, with each Series A-1 Unit entitled to one vote for each common unit into which such Series A-1 Unit is convertible.

As conversion is at the option of the holder and redemption is contingent upon a future event which is outside the control of the Partnership, the Series A-1 Units
have been classified as mezzanine equity in the consolidated balance sheets.

Under the Partnership Agreement, distributions on Series A-1 Units were made with paid-in-kind Series A-1 Units, cash or a combination thereof, at the discretion
of the Board of Directors. The sale of the Series A-1 Units was exempt from registration under Securities Act pursuant to Rule 4(a)(2) under the Securities Act.

Series A-2 Convertible Preferred Units

On March 30, 2015 and June 30, 2015, we entered into two Series A-2 Convertible Preferred Unit Purchase Agreements with Magnolia Infrastructure  Partners
("Magnolia") an affiliate of HPIP pursuant to which the Partnership issued, in separate private placements, newly-designated Series A-2 Units (the “Series A-2
Units”) representing limited partnership interests in the Partnership. As a result, the Partnership issued a total of 2,571,430 Series A-2 Units for approximately $ 45
million in  aggregate  proceeds  during  the  year  ended  December  31,  2015.  The  Series  A-2  Units  will  participate  in  distributions  of  the  Partnership  along  with
common units in a manner identical to the existing Series A-1 Units (together with the Series A-2 Units, the "Series A Units"), with such distributions being made
in cash or with paid-in-kind Series A Units at the election of the Board of Directors of our General Partner.

On July 27, 2015, we amended our Partnership Agreement to grant us the right (the “Call Right”) to require the holders of the Series A-2 Units to sell, assign and
transfer all or a portion of the then outstanding Series A-2 Units to us for a purchase price of $17.50 per Series A-2 Unit (subject to appropriate adjustment for any
equity distribution, subdivision or combination of equity interests in the Partnership). We may exercise the Call Right at any time, in connection with our or our
affiliate’s acquisition of assets or equity from ArcLight Energy Partners Fund V, L.P., or one of its affiliates, for a purchase price in excess of $100 million . We
may  not  exercise  the  Call  Right  with  respect  to  any  Series  A-2  Units  that  a  holder  has  elected  to  convert  into  common  units  on  or  prior  to  the  date  we  have
provided notice of our intent to exercise the Call Right, and we may also not exercise the Call Right if doing so would result in a default under any of our or our
affiliates’ financing agreements or obligations. As of December 31, 2017, the conversion price was $15.23 . The sale of the Series A-2 Units was exempt from
registration under Securities Act pursuant to Rule 4(a)(2) under the Securities Act.

As conversion is at the option of the holder and redemption is contingent upon a future event which is outside the control of the Partnership, the Series A-2 Units
have been classified as mezzanine equity in the consolidated balance sheets.

F-39

Series C Convertible Preferred Units

On April 25, 2016, the Partnership issued 8,571,429 of its Series C Units to an ArcLight affiliate in connection with the Emerald Transactions described in Note 3-
Acquisitions .

The Series C Units have voting rights that are identical to the voting rights of the common units and will vote with the common units as a single class on an as
converted basis, with each Series C Unit initially entitled to one vote for each common unit into which such Series C Unit is convertible. The Series C Units also
have separate class voting rights on any matter, including a merger, consolidation or business combination, that adversely affects, amends or modifies any of the
rights, preferences, privileges or terms of the Series C Units. The Series C Units are convertible in whole or in part into common units at any time. The number of
common units into which a Series C Unit is convertible will be an amount equal to the sum of $14.00 plus all accrued and accumulated but unpaid distributions,
divided by the conversion price. The sale of the Series C Units was exempt from registration under Securities Act pursuant to Rule 4(a)(2) under the Securities Act.

In the event that the Partnership issues, sells or grants any common units or convertible securities at an indicative per common unit price that is less than $14.00
per common unit (subject to customary anti-dilution adjustments), then the conversion price will be adjusted according to a formula to provide for an increase in
the number of common units into which Series C Units are convertible. As of December 31, 2017, the conversion price was $13.39 .

Prior to consummating any recapitalization, reorganization, consolidation, merger, spin-off or other business combination in which the holders of common units
are to receive securities, cash or other assets, we are obligated to make an irrevocable written offer, subject to consummating the Partnership Event, to the holders
of Series C Units to redeem all (but not less than all) of the Series C Units for a price per Series C Unit payable in cash as described in the Partnership Agreement.

Upon  receipt  of  a  redemption  offer,  each  holder  of  Series  C Preferred  Units  may  elect  to  receive  the  cash  amount  or  a  preferred  security  issued  by the  person
surviving or resulting from the Partnership Event and containing provisions substantially equivalent to the provisions set forth in the Partnership Agreement with
respect to the Series C Preferred Units without material abridgement.

Upon any liquidation and winding up of the Partnership or the sale of substantially all of the assets of the Partnership, the holders of Series C Units generally will
be entitled to receive, in preference to the holders of any of the Partnership's other equity securities but in parity with all convertible preferred units, an amount
equal to the sum of the $14.00 multiplied by the number of Series C Units owned by such holders, plus all accrued but unpaid distributions.

In connection with the issuance of the Series C Units, the Partnership issued to the holders (the "Series C Warrant"). The Series C Warrant is subject to standard
anti-dilution adjustments and is exercisable for a period of seven years.

On April 25, 2017, the number of common units that may be purchased pursuant to the exercise of the Series C Warrant was adjusted by an amount, rounded to the
nearest whole common unit, equal to the product obtained by the following calculation: (i) 400,000 multiplied by (ii) (A) the Series C Issue Price multiplied by the
number of Series C Units then outstanding less $45.0 million divided by (B) the Series C Issue Price multiplied by the number of Series C Units issued, less $45.0
million .  As  a  result  of  such  adjustment,  the  number  of  common  units  that  can  be  purchased  upon  the  exercise  of  the  Series  C  Warrant  increased  by  416,485
common units.

Any Series  C Units  issued  in-kind  as a distribution  to holders  of Series  C Units (“Series  C PIK Units”)  will increase  the number  of common  units that  can be
purchased  upon  exercise  of  the  Series  C  Warrant  by  an  amount,  rounded  to  the  nearest  whole  common  unit,  equal  to  the  product  obtained  by  the  following
calculation: (i) the total number of common units into which each Series C Warrant may be exercised immediately prior to the most recent issuance of the Series C
PIK Units multiplied by (ii) (A) the total number of outstanding Series C Units immediately after the most recent issuance of Series C PIK Units divided by (B) the
total number of outstanding Series C Units immediately prior to the most recent issuance of Series C PIK Units. As of December 31, 2017, the number of common
units that can be purchased upon the exercise of the Series C Warrant increased to 1,253,260 common units.

The fair value of the Series C Warrant was determined using a market approach that utilized significant inputs which are not observable in the market and thus
represent a Level 3 measurement as defined by ASC 820. The estimated fair value of $4.41 per warrant unit was determined using a Black-Scholes model and the
following  significant  assumptions:  i)  a  dividend  yield  of  18% ,  ii)  common  unit  volatility  of  42% and  iii)  the  seven -year  term  of  the  warrant  to  arrive  at  an
aggregate fair value of $4.5 million .

As conversion is at the option of the holder and redemption is contingent upon a future event which is outside the control of the Partnership, the Series C Units
have been classified as mezzanine equity in the consolidated balance sheets.

F-40

Series D Convertible Preferred Units

On October 31, 2016, Partnership issued 2,333,333 shares of its newly-designated Series D Units to an ArcLight affiliate at a price of $15.00 per unit, less a 1.5%
closing fee, in connection with the Delta House transaction described in Note 3 - Acquisitions . The fair value of the conditional Series D Warrant at the time of
issuance was immaterial.

On October 2, 2017, pursuant to the terms of our Partnership Agreement, we exercised our call right to repurchase all of the 2,333,333 outstanding Series D Units
from  Magnolia  for  approximately  $37.0  million  in  cash,  which  was  funded  through  our  Credit  Agreement.  Of  this  amount,  approximately  $2.5  million  was
associated with the dividend distribution associated with Series D Units, as reported in line item Distributions on our consolidated statements of cash flows. After
the closing date of such redemption, which occurred on October 2, 2017, there were no more outstanding Series D Units.

Our capital accounts are comprised of approximately 1.3% notional General Partner interest and 98.7% limited partner interests as of December 31, 2017 . Our
limited partners have limited rights of ownership as provided for under our Partnership Agreement and the right to participate in our distributions. Our General
Partner manages our operations and participates in our distributions, including certain incentive distributions pursuant to the incentive distribution rights that are
non-voting limited partner interests held by our General Partner. Pursuant to our Partnership Agreement, our General Partner participates in losses and distributions
based on its interest. The General Partner's participation in the allocation of losses and distributions is not limited and therefore, such participation can result in a
deficit  to  its  respective  capital  account.  As  such,  allocation  of  losses  and  distributions  for  previous  transactions  between  entities  under  common  control  have
resulted in a deficit to the General Partner's capital account included in our consolidated balance sheets.

Series B Convertible Preferred Units

Effective January 31, 2014, the Partnership issued 1,168,225 Series B Units to its General Partner in exchange for approximately $30.0 million to fund a portion of
the Lavaca acquisition described in Note 3 - Acquisitions . The Series B Units participated in

distributions of the Board of Directors of our General Partner along with common units, with such distributions being made in cash distributions or with paid-in-
kind Series B Units at the election of the Partnership. The Series B Units were issued in a private placement in reliance upon an exemption from the registration
requirements of the Securities Act of 1933 pursuant to Section 4(a)(2) thereof and the safe harbor provided by Rule 506 of Regulation D promulgated thereunder.
On February 1, 2016, all outstanding Series B Units were converted on a one -for-one basis into common units.

The Board of Directors of our General Partner elected to pay the Series B distributions using paid-in-kind Series B Units. For the year ended December 31, 2015,
the Partnership issued 94,923 of paid-in-kind Series B Units with a fair value of $1.4 million .

Equity Offerings

In October 2015, the Partnership and certain of its affiliates entered into an agreement with a group of investment banks under which it may issue up to $100.0
million of its common units in at the market (“ATM”) offerings. During 2016, the Partnership issued 248,561 common units under this program resulting in net
proceeds  of  $2.9  million  after  deducting  related  offering  costs  of  $0.3  million  .  The  net  proceeds  were  used  to  repay  amounts  outstanding  under  the  Credit
Agreement. At December 31, 2016, $96.8 million remained available under the ATM program. There were no offerings under the ATM program in 2017.

In September 2015, the Partnership sold 7.5 million of its common units in a public offering at a price to the public of $11.31  per common unit. The net proceeds
of  approximately  $81.0  million  were  used  to  fund  a  portion  of  the  Delta  House  investment  described  in  Note  3.  In  October  2016,  the  Partnership  issued  an
additional 151,937 common units at a price of $11.31 per unit pursuant to the partial exercise of the underwriters' overallotment option, resulting in net proceeds of
approximately $1.7 million .

General Partner Units

In  order  to  maintain  its  ownership  percentage,  we  received  proceeds  of  $4.0  million  from  our  General  Partner  as  consideration  for  the  issuance  of  additional
notional 284,886 general partner units for the year ended December 31, 2017, proceeds of $2.0 million from our General Partner as consideration for the issuance
of 143,900 additional notional general partner units for the year ended December 31, 2016, proceeds of $1.9 million for the issuance of 143,517 additional notional
general partner units for the year ended December 31, 2015.

On January 26, 2018 , the Board of Directors of our General Partner declared a quarterly cash distribution of $0.4125 per common unit or $1.65 per common unit
on an annualized basis. The distribution was paid on February 14, 2018 , to unitholders of record as of the close of business on February 7, 201 8. Accrued cash
distributions on our preferred convertible units were also paid in February 2018.

The fair value of the paid-in-kind distributions was determined using the market and income approaches, requiring significant inputs which are not observable in
the market and thus represent Level 3 measurements as defined by ASC 820. Under the income approach, the fair value estimates for all years presented were

ii) option values ranging from $0.02 per unit to $3.86 per unit using a Black-Scholes  model, iii) assumed discount rates  ranging from 5.57% to 10.0% and iv)
assumed growth rates of 1.0% .

Our Partnership Agreement provides that the General Partner may, in its sole discretion, make cash distributions, but there is no requirement that we make any cash
distributions.

17. Net Income (Loss) per Limited Partner Unit

Net  income  (loss)  is  allocated  to  the  General  Partner  and  the  limited  partners  in  accordance  with  their  respective  ownership  percentages,  after  giving  effect  to
distributions  on  our  convertible  preferred  units  and  General  Partner  units,  including  incentive  distribution  rights  ("IDRs").  Unvested  unit-based  compensation
awards that contain non-forfeitable rights to distributions (whether paid or unpaid) are classified as participating securities and are included in our computation of
basic and diluted net limited partners' net income (loss) per common unit. Basic and diluted limited partners' net income (loss) per common unit is calculated by
dividing limited partners' interest in net income (loss) by the weighted average number of outstanding limited partner units during the period.

The calculation of basic and diluted limited partners' net loss per common unit is summarized below (in thousands, except per unit amounts):

18. Incentive Compensation

Overview

Our  General  Partner  manages  our  operations  and  activities  and  employs  the  personnel  who  provide  support  to  our  operation.  Unit-based  awards,  which  are
available on a limited basis, or other types of incentive compensation such as our Defined Contribution Plan, which is available to all employees, are designed to
retain, motivate and reward talented employees and key management personnel.

Unit-Based Compensation Plans

All  equity-based  awards  issued  under  the  Long-Term  Incentive  Plan  consist  of  phantom  units,  distribution  equivalent  rights  ("DER"),  option  grants  or
performance-based awards. DERs, options and performance-based awards have been granted on a limited basis. Future awards may be granted at the discretion of
the Compensation Committee and subject to approval by the Board of Directors of our General Partner.

On  November  19,  2015,  the  Board  of  Directors  of  our  General  Partner  approved  the  Third  Amended  and  Restated  Long-Term  Incentive  Plan  to,  among  other
things,  increase  the  number  of  common  units  authorized  for  issuance  by  6,000,000 common  units.  On  February  11,  2016,  the  unitholders  approved  the  Third
Amended and Restated Long-Term Incentive Plan (as amended and in effect as of the date hereof, the "LTIP").

After  March  8,  2017,  pursuant  to  the  JPE  Merger,  we  assumed  the  JP  Energy  Partnership  2014  Long-Term  Incentive  Plan,  which  was  renamed  the  American
Midstream Partners, LP Amended and Restated 2014 Long Term Incentive Plan (the “Assumed LTIP”). As of December 31, 2017 , there were 151,845 Common
Units available for awards under the Assumed LTIP, as adjusted to reflect the JPE Merger. We settle the existing awards made under the Assumed LTIP with the
Common Units reserved under the Assumed LTIP. See JPE Unit-Based Compensation below for detailed information.

At December 31, 2017 , 2016 and 2015 , there were 4,134,412 , 5,017,528 and 15,484 common units, respectively, available for future grants under the LTIP.

Phantom  Unit  Awards.  Ownership  in  the  phantom  unit  awards  is  subject  to  forfeiture  until  the  vesting  date.  The  LTIP  is  administered  by  the  Compensation
Committee of the Board of Directors of our General Partner, which at its discretion, may elect to settle such vested phantom units with a number of common units
equivalent to the fair market value at the date of vesting in lieu of cash. Although our General Partner has the option to settle vested phantom units in cash, our
General Partner has not historically settled these awards in cash. Under the LTIP, phantom units typically vest in increments of 25% on each grant anniversary date
and do not contain any vesting requirements other than continued employment.

In December 2015, the Board of Directors of our General Partner approved a grant of 200,000 phantom units under the LTIP which contain DERs to the extent the
Partnership’s  Series  A  Preferred  Unitholders  receive  distributions  in  cash.  These  units  will  vest  on  the  three year  anniversary  of  the  date  of  grant,  subject  to
acceleration in certain circumstances.

The following table summarizes activity in our phantom unit-based awards for the years ended December 31, 2017, 2016 and 2015 (in thousand, except per unit

(1) The intrinsic value of phantom units was calculated by multiplying the closing market price of our underlying units on December 31, 2017, 2016, 2015 and 2014
by the number of phantom units.

(2) Including 10,344 of phantom units which remain outstanding from the Assumed LTIP.

The fair value of our phantom units, which are subject to equity classification, is derived from the fair value of our common units at the grant date. Fair value of
phantom  units is calculated  based on either  a) the market  price  of underlying  units on the date of grant,  less the estimated  life time  (vesting period)'s  dividend
distribution, if the phantom units have a restricted feature associated with the distribution or b) the market price of underlying units on the date of grant.

Compensation expense related to these phantom unit based awards for the years ended December 31, 2017 , 2016 , and 2015 was $7.9 million , $3.6 million and
$3.8  million  ,  respectively,  and  is  included  in  Corporate  expenses  and  Direct  operating  expenses  in  our  consolidated  statements  of  operations  and  the  Equity
compensation expense in our consolidated statements of changes in equity, partners' capital and noncontrolling interests.

The total fair value of units at the time of vesting was $9.8 million , $2.4 million , and $2.6 million for the years ended December 31, 2017 , 2016 , and 2015 ,
respectively.

Equity compensation expense related to unvested phantom awards not yet recognized at December 31, 2017 was $6.0 million and the weighted average period over
which this expense is expected to be recognized as of December 31, 2017 is approximately 1.43 years.

Performance  and  Service  Condition  Awards  .  In  November  2015,  the  Board  of  Directors  of  our  General  Partner  modified  awards  that  introduced  certain
performance  and  service  conditions  that  were  probable  of  being  achieved,  amounting  to  $2.0 million payable  to certain  employees.  During the third quarter  of
2016, we settled $1.0 million of the obligation in cash while in the fourth quarter of 2016, forfeitures reduced the total payable amount from $2.0 million to $1.5
million . These awards are accounted for as liability classified awards. Compensation expense related to these awards for the years ended December 31, 2017 and
2016 was $0.2 million and $0.9 million , respectively, and is included in Direct operating expenses in our consolidated statements of operations. The remaining
unrecognized compensation expense related to unvested awards as of December 31, 2017 was $0.1 million .

Option  to  Purchase  Common  Units  . In  December  2015,  the  Board  of  Directors  of  our  General  Partner  approved  the  grant  of  an  option  to  purchase  200,000
common units at an exercise price per unit equal to $7.50 . The grant will vest on January 1, 2019, subject to acceleration in certain circumstances, and will expire
on March 15th of the calendar year following the calendar year in which it completely vests.

In August 2016, the Board of Directors of our General Partner approved the grant of an option to purchase 30,000 common units at an exercise price per unit equal
to $12.00 . The grant will vest on July 31, 2019, subject to continued employment, and will expire on July 31st of the calendar year following the calendar year in
which it vests.

In  September  2016,  the  Board  of  Directors  of  our  General  Partner  approved  the  grant  of  options  to  an  executive  to  purchase  45,000  common  units  of  the
Partnership at an exercise price per unit equal to $13.88 . The options were to vest at a rate of 25% per year and to expire on September 30th of the calendar year
following the calendar year in which they completely vest. Such options have been forfeited during 2017.

In April 2017, the Board of Directors of our General Partner approved the grant of options to purchase 15,000 common units of the Partnership at an exercise price
per unit equal to $14.85 . The options will vest over four years at a rate of 25% per year. The options will expire on April 30th of the calendar year following the
calendar year in which they completely vest.

The Black-Scholes pricing model was used to determine the fair value of our option grants using the following assumptions:

Weighted average common unit price volatility

Expected distribution yield

Weighted average expected term (in years)

Weighted average risk-free rate

The  weighted  average  unit  price  volatility  was  based  upon  the  historical  volatility  of  our  common  units.  The  expected  distribution  yield  was  based  on  an
annualized distribution divided by the closing unit price on the date of grant. The risk-free rate was based on the U.S. Treasury yield curve in effect on the date of
grant with a term equivalent to the vesting period.

Compensation  expense  related  to  these  option  awards  was not material  for  the years  ended  December 31, 2017 , 2016 and 2015. Compensation  cost related  to
unvested option awards not yet recognized at December 31, 2017 was $0.1 million .

Performance Based Awards. In November 2017, the Board of Directors of our General Partner approved the grant of 524,000 performance based awards ("PSUs")
to create a highly accretive, long-term retention tool to key personnel whom management expects to drive performance over the long-term. The awards will vest on
November 20, 2022, subject to acceleration in certain circumstances.

JPE Unit-Based Compensation

Long-Term Incentive Plan and Phantom Units. The JPE 2014 Long-Term Incentive Plan (or “Assumed LTIP” following the JPE Merger) authorized grants of up
to 3,642,700 common  units.  Phantom units  issued under  the Assumed LTIP were primarily  composed  of two types of grants:  (1)  service  condition  grants  with
vesting over three years in equal annual installments; and (2) service condition grants with cliff vesting on April 1, 2018. Distributions related to these unvested
phantom units are paid concurrent with our distribution for common units. The fair value of phantom units issued under the Assumed LTIP was determined by
utilizing the market value of our common units on the respective grant date.

The following table presents phantom units activity for the years ended December 31, 2015 to 2016:

(1) Post-acquisition date March 8, 2017 of JPE by the Partnership, as discussed in Note 3 - Acquisitions, the Assumed LTIP was adopted by the Partnership, as
discussed above. All the 312,992 shares under Assumed LTIP have become part of the LTIP program, as disclosed in Phantom Unit Awards above.

As a result of the JPE Merger, certain JPE unit-based awards have been modified for JPE employees who stayed for the transition period. Such awards with a vest
date of April 1, 2018 have been modified over the requisite service period to their respective target completion dates of April 8, 2017, May 31, 2017, July 14, 2017
or September 8, 2017. The incremental fair value of
the modified awards which was recorded prospectively within 2017 was based on the conversion ratio (of JPE phantom units to the Partnership's units) multiplied
by the Partnership's unit price on the date immediately preceding the acquisition date of March 8, 2017 of $16.45 . The total fair value of JPE modified awards was
approximately $1.5 million and was expensed in the year ended December 31, 2017.

Total  unit-based  compensation  expense  related  to  the  Assumed  LTIP  was  $1.7  million  and  $0.8  million  for  the  years  ended  December  31,  2016  and  2015,
respectively, which was recorded in Corporate expenses in the consolidated statements of operations. The unit-based compensation expense related to the Assumed
LTIP for the year ended December 31, 2017 was included in the total phantom unit-based compensation for the year ended December 31, 2017, as discussed in
Phantom Unit Awards above, as a result of the JPE Merger.

Defined Contribution Plan

We  have  an  employee  savings  plan  (the  "401(k)  Plan")  under  Section  401(k)  of  the  Internal  Revenue  Code  of  1986,  as  amended,  whereby  employees  of  our
General Partner may contribute a portion of their base compensation to the employee savings plan,

F-48

 
 
 
 
 
 
 
 
 
 
 
 
 
subject to limits. We provide a matching contribution each payroll period equal to  100%  of the employee's contribution up to the lesser of  6%  of the employee's
eligible  compensation  or    $16,200   annually  for  the  period.  The  matching  contribution  vests  immediately  upon  eligibility,  which  is  defined  as  first  day  of
employment. As a result of the JPE Merger, the 401(k) Plan of JPE is included in our financial statements for the periods presented.

The following table summarizes information regarding contributions and the expense recognized for the matching contributions, which is included in operating and

On December 22, 2017, the United States enacted the Tax Cuts and Jobs Act of 2017 (“Tax Reform Act”). Among a number of significant changes to the current
U.S. federal income tax rules, the Tax Reform Act reduces the marginal U.S. corporate income tax rate from 34 percent to 21 percent, limits the current deduction
for net interest expense, limits the use of net operating losses to offset future taxable income, and provides for full expense deduction for certain business capital
expenditures for 2018 and subsequent years. The tax rates used in calculating deferred income taxes reflect the enacted tax law.

As of December  31,  2017  ,  certain  subsidiaries  in  our  Terminalling  Services  segment  had  net  operating  loss  carryforwards  for  federal  income  tax  purposes  of
approximately $26.0 million which begin to expire in 2029.

We recognize the tax benefits from uncertain tax positions if it is more likely than not that the position will be sustained on examination by the taxing authorities.
As of December 31, 2017, we have not recognized tax benefits relating to uncertain tax positions.

The  preparation  of  our  income  tax  returns  requires  the  use  of  management's  estimates  and  interpretations  which  may  be  subjected  to  review  by  the  respective
taxing  authorities  and  may  result  in  an  assessment  of  additional  taxes,  penalties  and  interest.  Tax  years  subsequent  to  2011  remain  subject  to  examination  by
federal and state taxing authorities.

20. Commitments and Contingencies

Contingencies

Legal proceedings

We  are  not  currently  party  to  any  pending  litigation  or  governmental  proceedings,  other  than  ordinary  routine  litigation  incidental  to  our  business.  While  the
ultimate impact of any proceedings cannot be predicted with certainly, our management believes that the resolution of any of our pending proceedings will not
have a material adverse effect on our financial condition or results of operations.

Environmental matters

We  are  subject  to  federal  and  state  laws  and  regulations  relating  to  the  protection  of  the  environment.  Environmental  risk  is  inherent  in  our  operations  and  we
could, at times, be subject to environmental cleanup and enforcement actions. We attempt to manage this environmental risk through appropriate environmental
policies and practices to minimize any impact our operations may have on the environment.

Exit and disposal costs

On March 9, 2016, management committed to a corporate headquarters relocation plan and communicated that plan to the impacted employees. The plan included
relocation assistance or one-time termination benefits for employees who rendered service until their respective termination dates. Charges associated with these
termination  benefits,  which  totaled  $9.1  million  were  recognized  ratably  over  the  requisite  service  period  and  are  presented  in  Corporate  expenses  in  our
consolidated statements of operations.

As part of the JPE Merger on March 8, 2017, management of JPE communicated to its employees a severance plan. The plan includes termination benefits in the
form of severance and accelerated vesting of phantom units for employees who rendered

(1)  Upon  closing  of  the  JPE  Merger,  the  proceeds  from  the  8.50%  Senior  Notes  were  used  to  repay  the  JPE  Credit  Agreement.  On  December  28,  2017,  the

Partnership issued an additional $125 million 8.50% Senior Notes, as discussed in Note 14 - Debt Obligations.

(2) In certain cases, there is insufficient information to reasonably determine the timing and/or method of settlement for purposes of estimating the fair value of the
ARO. In such cases, the ARO cost is considered indeterminate because there is no data or information that can be derived from past practice, industry practice,
management's experience, or the asset's estimated economic life.

21. Related-Party Transactions

To the extent applicable, our discussion below includes the nature of our relationship and activities that we had with our Related Parties, as defined and required by
ASC 850 - Related Party Disclosures, in the year ended December 31, 2017 and comparative periods, if applicable. Balances associated with our investments in
unconsolidated affiliates are disclosed in Note 10 - Investments in unconsolidated affiliates.

Blackwater Midstream Holdings, LLC

In  December  2013,  we  acquired  Blackwater  Midstream  Holdings,  LLC  (“Blackwater”)  from  an  affiliate  of  ArcLight.  The  acquisition  agreement  included  a
provision whereby an ArcLight affiliate  would be entitled to an additional $5.0 million of merger consideration based on Blackwater meeting certain operating

which is included in Accrued expense and other current liabilities in the accompanying consolidated balance sheets.

Republic Midstream, LLC

Republic  Midstream,  LLC  (“Republic”),  is  an  entity  owned  by  ArcLight  in  which  we  charge  a  monthly  fee  of  approximately  $0.1  million  .  The  monthly  fee
reduced the Corporate expenses in our consolidated statements of operations by $1.0 million for the year ended December 31, 2017. The services agreement with
Republic terminated according to its terms in September 2017 and services were no longer provided to Republic. As of December 31, 2017, and 2016, we had a
receivable balance due from Republic of $0.8 million and $1.7 million , respectively.

F-51

 
 
 
 
 
 
 
 
 
 
 
 
 
The  Partnership  also  performed  certain  management  services  for  Republic  in  exchange  for  a  monthly  fee  of  approximately  $75,000 .  In  September  2016,  this
monthly fee decreased to approximately $40,000 before ceasing in November 2016. For the years ended December 31, 2016 and 2015, the Partnership charged a

General Partner

Employees of our General Partner are assigned to work for us or other affiliates of our General Partner. Where directly attributable, all compensation and related
expenses for these employees are charged directly by our General Partner to our wholly-owned subsidiary, American Midstream, LLC, which, in turn, charges the
appropriate subsidiary or affiliate. Our General Partner does not record any profit or margin on the expenses charged to us.

In connection with the acquisition of JPE by the Partnership on March 8, 2017, our General Partner agreed to provide quarterly financial support up to a maximum
of $25.0 million . The financial support will continue for eight ( 8 ) consecutive quarters following the closing of the acquisition, or earlier, until $25.0 million in

Separate from the financial support described above, our General Partner also agreed to absorb $17.6 million corporate overhead expenses, which were incurred by
and  reimbursed  to  us  in  2017.  This  amount,  the  amount  in  the  preceding  paragraph,  and  the  $3.9  million  received  related  to  the  General  Partner’s  ownership
percentage,  totaled  approximately  $46.5 million which  was  presented  as  part  of  the  contribution  line  item  on  our  consolidated  statements  of  cash  flows.  As  of

Our  operations  are  located  in  the  United  States  and  are  organized  into  the  following  five reportable  segments:  Gas  Gathering  and  Processing  Services,  Liquid
Pipelines  and  Services,  Natural  Gas  Transportation  Services,  Offshore  Pipeline  and  Services,  and  Terminalling  Services.  These  segments,  are  described  below,
have been identified based on the differing products and services, regulatory environments and the expertise required for these operations.

Gas Gathering and Processing Services provides “wellhead-to-market” services to producers of natural gas and crude oil, which include transporting raw

natural gas and crude oil from various receipt points through gathering systems, treating the

raw natural gas, processing raw natural gas to separate the NGLs from the natural gas, fractionating NGLs, and selling or delivering pipeline-quality natural gas
and NGLs to various markets and pipeline systems.

Liquid  Pipelines  and  Services  provides  transportation,  purchase  and  sales  of  crude  oil  from  various  receipt  points  including  lease  automatic  custody

transfer ("LACT") facilities and delivering to various markets.

Natural Gas Transportation Services transports and delivers natural gas from producing wells, receipt points or pipeline interconnects for shippers and

other customers, which include local distribution companies (“LDCs”), utilities and industrial, commercial and power generation customers.

Offshore Pipelines and Services gathers and transports natural gas from various receipt points to other pipeline interconnects, onshore facilities and other

delivery points.

Terminalling Services provides above-ground leasable storage operations at our marine terminals that support various commercial customers, including
commodity  brokers,  refiners  and  chemical  manufacturers  to  store  a  range  of  products  and  also  includes  crude  oil  storage  in  Cushing,  Oklahoma  and  refined
products terminals in Texas and Arkansas.

Segment Gross Margin per Segment

Our Chief Executive Officer serves as our Chief Operating Decision Maker and evaluates the performance of our reportable segments primarily on the basis of
segment gross margin, which is our segment measure of profitability. We define segment gross margin for each segment as summarized below:

Gas Gathering and Processing Services - total revenue plus unconsolidated affiliate earnings less unrealized gains (losses) on commodity derivatives, construction
and operating management agreement income and less the cost of sales.

Liquid Pipelines and Services - total revenue plus unconsolidated affiliate earnings less unrealized gains (losses) on commodity derivatives and construction and
operating management agreement income less the cost of sales. Substantially all of our gross margin in this segment is fee-based or fixed-margin, with little to no
direct commodity price risk.

Natural Gas Transportation Services - total revenue plus unconsolidated affiliate earnings and construction and operating management agreement income less the
cost of sales. Substantially all of our gross margin in this segment is fee-based or fixed-margin, with little to no direct commodity price risk.

Offshore Pipelines and Services - total revenue plus unconsolidated affiliate earnings less the cost of sales. Substantially all of our gross margin in this segment is
fee-based or fixed-margin, with little to no direct commodity price risk.

Terminalling  Services  -  total  revenue  less  cost  of  sales  and  direct  operating  expense  which  includes  direct  labor,  general  materials  and  supplies  and  direct
overhead.

Goodwill and Intangible Assets, Net for more information .  

(2)   We recognized asset impairment charges of $116.6 million and $0.7 million in the fourth quarters of 2017 and 2016, respectively. Of these $116.6 million
impairment charges in 2017, $103.9 million are related to our property, plant and equipment and $12.7 million are related to intangible assets, as discussed
in Note 9 - Property, Plant and Equipment and Note 10 - Goodwill and Intangible Assets, Net .

(3)   Total  revenues  and  cost  of  sales  for  the  fourth  quarter  of  2017  have  been  reduced  by  approximately  $13.7  million  primarily  due  to  an  out-of-period
adjustment  recorded  during  the  quarter  related  to  an  error  in  gross  versus  net  revenue  recognition.    This  adjustment  did  not  have  a  material  impact  to
revenue for any prior quarters and had no impact to operating loss, net income (loss) or segment margin for any period.

(4)  Our  quarterly  selected  data  have  been  recasted  to  reflect  the  sale  of  the  Propane  Business  on  September  1,  2017.  For  more  information,  see  Note  4  -

Distribution

On January 26, 2018 , we announced that the Board of Directors of our General Partner declared a quarterly cash distribution of $0.4125 per common unit for the
fourth quarter ended December 31, 2017, or $1.65 per common unit on an annualized basis. The distribution was paid on February 14, 2018 , to unitholders of
record as of the close of business February 7, 2018 .

Sales of the Refined Products Business

On February  16,  2018,  the  Partnership  entered  into  a  definitive  agreement  for  the  sale  of  the  Refined  Products Terminals  (the  "Refined  Products  Business")  to
DKGP  Energy  Terminals  LLC,  a  joint  venture  between  Delek  Logistics  Partners,  LP  and  Green  Plains  Partners  LP,  for  approximately  $138.5 million in cash,
subject to working capital adjustments. Closing of the sale of the Refined Products Business is subject to customary closing conditions, including clearance under
the Hart-Scott-Rodino Act.

The  transaction  is  expected  to  close  in  the  first  half  of  2018.  The  Refined  Products  Business  consists  of  two terminal  facilities,  located  in  Caddo Mills,  Texas
("Caddo Mills") and North Little Rock, Arkansas ("NLR").

Southcross Unitholder Approval of Merger

On March 27, 2018, a majority of the common unitholders of Southcross Energy Partners, L.P. voted to approve the previously announced proposed merger with
the Partnership. The closing of the merger remains subject to certain state level regulatory approvals and the closing conditions described in the definitive proxy
statement filed with the Securities and Exchange Commission on February 13, 2018. The merger is expected to close later in the second quarter of 2018.     

Delta House Capital Contribution Agreement

On  March  11,  2018,  the  Partnership  and  Magnolia,  an  affiliate  of  ArcLight,  entered  into  a  Capital  Contribution  Agreement  to  provide  additional  capital  and
corporate overhead support to the Partnership during the first three quarters of 2018 in connection with temporary curtailment of production flow at Delta House.
Pursuant to the Agreement,  Magnolia has agreed  to provide support to the Partnership in an amount to be agreed, up to the difference  between the actual cash
distribution received by the Partnership on account of its interest in Delta House and the quarterly cash distribution expected to be received if production flow to
Delta House had not been not curtailed.

by  you  in  any  way  (whether  by  operation  of  law  or  otherwise),  other  than  by  will  or  the  laws  of  descent  and  distribution  and  shall  not  be  subject  to
execution, attachment, or similar process. Upon any attempt by you to transfer, assign, pledge, hypothecate, or otherwise dispose of such rights contrary
to the provisions in this Agreement or the Plan, or upon the levy of any attachment or similar process upon such rights, such rights shall immediately
become null and void.

Restrictions . By accepting this grant, you agree that any Units that you may acquire upon payment of this Award will not be sold or otherwise disposed
of in any manner that would constitute a violation of any applicable federal or state securities laws. You also agree that (i) any certificates representing the
Units acquired  under this Award may bear  such legend  or legends  as the Committee  deems  appropriate  in order  to assure  compliance  with applicable
securities laws and any restrictions set forth in this Agreement, (ii) the Company may refuse to register the transfer of the Units to be acquired under this
Award  on  the  transfer  records  of  the  Partnership  if  such  proposed  transfer  would  in  the  opinion  of  counsel  satisfactory  to  the  Partnership  constitute  a
violation  of any applicable  securities  law, and (iii)  the Partnership  may give related  instructions  to its transfer  agent, if any, to stop registration  of the
transfer of the Units to be acquired under this Award.

Withholding of Taxes . To the extent that the grant, vesting or payment of any amounts pursuant to this Award results in the receipt of compensation by
you with respect to which the Company or an Affiliate has a tax withholding obligation pursuant to applicable law, unless other arrangements have been
made  by  you  that  are  acceptable  to  the  Company  or  such  Affiliate,  you  shall  deliver  to  the  Company  or  the  Affiliate  such  amount  of  money  as  the
Company or the Affiliate may require to meet its withholding obligations under such applicable law. If you fail to do so, the Company is authorized to
withhold from any cash or Unit remuneration (including withholding any Units to be distributed to you under this Agreement) then or thereafter payable
to you any tax required to be withheld by reason of such resulting compensation income. No payment of a vested Phantom Unit shall be made pursuant to
this  Agreement  until  you  have  paid  or  made  arrangements  approved  by  the  Company  or  the  Affiliate  to  satisfy  in  full  the  applicable  tax  withholding
requirements of the Company or Affiliate with respect to such event.

law,  unless  other  arrangements  have  been  made  by  Participant  that  are  acceptable  to  the  Company  or  such  Affiliate  for  the  satisfaction  of  such  withholding

Opinion on the Financial Statements

We  have  audited  the  accompanying  balance  sheets  of  Pinto  Offshore  Holdings,  LLC  (the  “Company”)  as  of  December  31,  2017  and  2016,  the  related
statements of income, changes in members’ equity, and cash flows for each of the two years in the period ended December 31, 2017 and for the period from
September 9, 2015 (Inception) through December 31, 2015, 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  at  December  31,  2017  and  2016,  and  the  results  of  its
operations and its cash flows for each of the two years in the period ended December 31, 2017 and the period from September 9, 2015 (Inception) through
December 31, 2015, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

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

We conducted our audits in accordance with the standards of the PCAOB and in accordance with auditing standards generally accepted in the United States
of America.  Those standards require  that we plan  and perform  the  audit to obtain reasonable  assurance  about whether the financial  statements  are  free of
material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial
statements,  whether  due  to  error  or  fraud,  and  performing  procedures  that  respond  to  those  risks.  Such  procedures  included  examining,  on  a  test  basis,
evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant
estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable
basis for our opinion.

We have served as the Company's auditor since 2015. Houston, Texas

1. Organization and Nature of Operations

Pinto Offshore Holdings, LLC (the “Company”) was formed in the state of Delaware as a limited  liability  company on September  9, 2015. The Company will
continue in existence until it is dissolved and terminated by the members of the Company in accordance with the provisions of the Amended and Restated Limited
Liability  Agreement  (the  “LLC  Agreement”).  The  purpose  of  the  Company  is  to  directly  or  indirectly  acquire,  own,  hold,  manage,  and  dispose  of  the  limited
liability  company  interests  of  Delta  House  FPS,  LLC,  a  Delaware  limited  liability  company  (“FPS”),  and  Delta  House  Oil  and  Gas  Lateral,  LLC,  a  Delaware
limited liability company (“OGL”).

OGL receives and transports hydrocarbons from the Marmalard, Neidermeyer, and SOB II prospects (the “Anchor Prospects”), the Blue Wing Olive, Malachite,
and SOB III prospects (the “Secondary Prospects”), and the Otis, Odd Job, LaFemme, and Red Zinger prospects (the “Additional Priority Prospects”) in the Gulf
of  Mexico,  and  any  future  additional  prospects  from  a  floating  production  system  (the  “Base  FPS”),  which  has  been  developed  and  is  operated  by  FPS,  to
commercial pipeline operators. The Base FPS and the oil and gas lateral transportation facilities initiated operations in April 2015.

Profits  and  losses  are  allocated  to  the  members  in  proportion  to  their  equity  percentage  interests.  Assets  were  contributed  to  the  Company  and  all  privileges,
preferences, duties, liabilities, obligations, and rights set forth in the LLC Agreement commenced on September 18, 2015.

The Company has reviewed its relationships with FPS and OGL and determined that the relationships meet the criteria to be considered variable interest entities
(“VIEs”) as defined by Financial Accounting Standards Board Accounting Standards Codification (“FASB ASC”) 810, Consolidation . However, the Company
has determined it does not have the power to direct the activities of FPS and OGL that most significantly impact their performance, such as oversight of day-to-day
operations,  hiring,  scheduling,  and  maintaining  the  workforce  that  operates  FPS  and  OGL,  ongoing  repairs  and  maintenance  including  selecting  and  hiring  the
contractors or employees performing that work, and operating the facilities. The power to direct those activities and decisions are held by FPS and OGL’s operator.
Additionally, there are no substantive kick-out or liquidation rights to remove the operator. As the Company is not the primary beneficiary of FPS and OGL, but
can exercise significant influence, the Company accounts for its investments in FPS and OGL as equity method investments.

2. Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation

The financial statements have been prepared in U.S. dollars using accounting principles generally accepted in the United States ("GAAP").

Equity Method Investments

Investments in which the Company has the ability to exercise significant influence, but are not deemed to have control, are accounted for under the equity method.
The Company’s unconsolidated  affiliates,  FPS and OGL, are accounted  for under the equity method. The investment  in unconsolidated  affiliates  represents  the
carrying  amount on the Company’s balance  sheet of its  investment  in its equity  method  investees.  This is not an indicator  of the fair value  of the investments,
rather it is the initial cost adjusted for the entity's share of earnings and losses of the investees, adjusted for any distributions (dividends) and other than temporary
impairment  losses  recognized.  Equity  in  the  earnings  of  unconsolidated  affiliates  reported  on  the  statement  of  income  represents  the  Company’s  proportionate
share of the net income of its investees for the period to which the equity method of accounting is applied. The recoverability of equity method investments are
evaluated  when  events  or  changes  in  circumstances  indicate  that  the  carrying  amount  of  the  investments  might  not  be  recoverable.  No  impairment  losses  were
recorded during the years ended December 31, 2017, 2016 and 2015.

Exhibit 99.1

Notes to Financial Statements

Use of Estimates

When preparing  financial  statements  in conformity  with U.S. GAAP, management  must make estimates  and assumptions based on information  available  at the
time. These estimates and assumptions affect the reported amounts of assets, liabilities, revenues and expenses, as well as the disclosures of contingent assets and
liabilities as of the date of the financial statements. Estimates and assumptions are based on information available at the time such estimates and assumptions are
made. Adjustments made with respect to the use of these estimates and assumptions often relate to information not previously available. Uncertainties with respect
to such estimates and assumptions are inherent in the preparation of financial statements. Actual results could differ materially from estimated amounts.

Concentration of Credit Risk

The  Company’s  investments  in  unconsolidated  affiliates  are  composed  of  operations  located  in  the  Gulf  of  Mexico  which  provide  infrastructure  capacity  and
transportation services to producers of oil and natural gas. Those affiliates have a concentration of accounts receivable balances due from companies engaged in the
production of oil and natural gas in the Gulf of Mexico. The affiliates’ customers may be similarly affected by changes in economic, regulatory, weather, or other
factors.

Income Taxes

The Company files its federal income tax return as a limited liability corporation under the Internal Revenue Code. In lieu of corporate income taxes, the members
of the Company are taxed on their proportionate share of the Company’s taxable income. Accordingly, no provision or liability has been recognized for federal
income tax purposes in the accompanying financial statements, as taxes are the responsibility of the individual members of the Company.

Each income tax position is assessed using a two-step process. A determination is first made as to whether it is more likely than not that the income tax position
will be sustained, based upon technical merits, upon examination by the taxing authorities. If the income tax position is expected to meet the more likely than not
criteria, the benefit recorded in the financial statements equals the largest amount that is greater than 50% likely to be realized upon its ultimate settlement. The
Company had no uncertain tax positions as of December 31, 2017 and 2016. For the years ended December 31, 2017 and 2016, and for the period from September
9, 2015 (Inception) through December 31, 2015, the Company did not incur any income tax-related interest or penalties.

Recent Accounting Pronouncements

In  August  2016,  the  FASB  issued  ASU  No.  2016-15,  Statement  of  Cash  Flows  (Topic  230):  Classification  of  Certain  Cash  Receipts  and  Cash  Payments  (a
consensus of the Emerging Issues Task Force) . The ASU intends to reduce diversity in practice on how the following cash activities are presented in the statement
of cash flows: (1) debt prepayment or debt extinguishment costs; (2) settlement  of zero-coupon debt instruments; (3) contingent considerations payments made
after a business combination; (4) proceeds from the settlement of insurance claims; (5) proceeds from the settlement of corporate and bank-owned life insurance
policies;  (6)  distributions  received  from  equity  method  investments;  and  (7)  beneficial  interests  in  securitization  transactions.  The  guidance  also  describes  a
predominance principle in which cash flows with aspects of more than one class that cannot be separated should be classified based on the activity that is likely to
be the predominant source or use of cash flow. The guidance is effective for public entities for annual and interim periods beginning after December 15, 2017. The
applicable update relates to distributions received from equity method investees and prescribes two options for presenting these cash flows: cumulative earnings
approach or nature of the distribution approach. At present, the Company applies the cumulative earnings approach, where the distributions received are considered
returns  on investment  and classified  as cash inflows  from operating  activities.  The Company is currently  evaluating  the impact  of the guidance on its financial
statements, and will adopt the new standard on its effective date, January 1, 2018.

3. Commitments and Contingencies

Legal Proceedings

The Company is not currently party to any pending litigation or governmental proceedings, other than ordinary routine litigation incidental to its business. While
the ultimate impact of any proceedings cannot be predicted with certainty, the Company believes that the resolution of any of its pending proceedings will not have
a material effect on its financial condition or results of operations.

Environmental Matters

Both FPS and OGL are subject to federal and state laws and regulations relating to the protection of the environment. Environmental risk is inherent to processing
platform operations and oil and natural gas pipeline transportation, and the Company, at times, in connection with its investment in FPS and OGL, could be subject
to environmental cleanup and enforcement actions. In October 2017, an oil leak occurred in the Gulf of Mexico due to a fracture in a flow line jumper connected to
the Base FPS, and as a precautionary measure, the Neidermeyer wells were shut-in. FPS and OGL have been advised by the producers responsible for these wells,
that the wells are expected to be shut-in until early to mid-2018 while environmental cleanup efforts continue. FPS and OGL believe they are not responsible for
the oil leak nor are they liable for any costs associated with the oil leak. As such, no liabilities have been recorded relating to this matter. The Company is not
aware of any other material environmental matters.

4. Investments in Unconsolidated Affiliates

The  change  in  the  Company’s  investments  in  FPS  and  OGL  for  the  years  ended  December  31,  2017  and  2016,  and  for  the  period  from  September  9,  2015

As holders of 27.93% of the Class A membership units of FPS and OGL, the Company is exposed to the risk of loss of its entire investment. Additionally, pursuant
to the Amended and Restated Limited Liability Company Operating Agreements for both FPS and OGL, Class A members can be required to contribute additional
funds for operating costs to the extent such operating costs exceed available cash held by FPS or OGL and for expansion projects as voted upon by the Class A
members.

5. Members’ Equity

There  is  one  class  of  equity  units  (the  “Units”),  as  established  by  the  LLC  Agreement,  which  may  be  divided  into  one  or  more  types,  classes,  or  series,  in
accordance  with the terms  and conditions of the  LLC Agreement.  The Units shall have the privileges,  preferences,  duties,  liabilities,  obligations,  and rights  set
forth in the LLC Agreement. There were 10,000 units authorized and outstanding as of December 31, 2017 and 2016.

For purposes of adjusting the capital accounts of the members, the net profits, net losses, and, to the extent necessary, individual items of income, gain, loss and
deduction,  for  any  fiscal  year,  or  other  period,  shall  be  allocated  among  the  members  in  a  manner  such  that  the  adjusted  capital  account  of  each  member,
immediately  after  making  such  allocation,  is,  as  nearly  as  possible,  equal  (proportionately)  to  then  distributions  that  would  be  made  to  such  member  if  the
Company were dissolved, its affairs wound up, and its properties sold for cash equal to their gross asset values, all Company liabilities were satisfied (limited with
respect to each nonrecourse liability to the gross asset value of the asset securing such liability), and the net assets of the Company were distributed to the members
immediately after making such allocation.

On September 18, 2015, Toga Offshore, LLC (“Toga”), the majority owner of Stork Offshore Holdings, LLC, and an affiliate of ArcLight Asset Management,
LLC (“ArcLight”), contributed their ownership interest in FPS (approximately 49%) to the Company. Subsequently, on September 18, 2015, American Midstream
Delta  House,  LLC  (an  affiliate  of  American  Midstream  Partners,  LP)  (“AMID”),  purchased  a  26.38%  interest  in  the  Company,  resulting  in  AMID  owning  an
approximate 12.9% indirect interest in FPS. On September 29, 2017, the Company distributed a 15.51% ownership interest in FPS to Toga and a 5.56% ownership
interest in FPS to AMID and, in accordance with FASB ASC 845-10-30-10 and FASB ASC 505-60-25-2, accounted for the distribution as a reduction of $30,504
in its equity method investment in FPS and members’ equity at the proportional carrying value of the
investment.  Subsequently,  on  September  29,  2017,  D-Day  Offshore  Holdings,  LLC  (an  affiliate  of  American  Midstream  Partners,  LP)  (“D-Day”),  purchased  a
15.51%  ownership  interest  in  FPS  from  Toga,  and  AMID  contributed  a  5.56%  ownership  interest  in  FPS  to  D-Day.  This  transaction  resulted  in  the  Company
holding 27.93% of the Class A membership units of FPS as of September 29, 2017.

On September  18, 2015,  Toga,  the  majority  owner  of  Otter  Offshore  Holdings,  LLC, and an  affiliate  of  ArcLight,  contributed  their  ownership  interest  in  OGL
(approximately 49%) to the Company. Subsequently, on September 18, 2015, AMID purchased a 26.38% interest in the Company, resulting in AMID owning an
approximate  12.9%  indirect  interest  in  OGL.  On  September  29,  2017,  the  Company  distributed  a  15.51%  ownership  interest  in  OGL  to  Toga  and  a  5.56%
ownership interest in OGL to AMID and, in accordance with FASB ASC 845-10-30-10 and FASB ASC 505-60-25- 2, accounted for the distribution as a reduction
of $38,610 in its equity method investment in OGL and members’ equity at the proportional carrying value of the investment. Subsequently, on September 29,
2017, D-Day purchased a 15.51% ownership interest in OGL from Toga, and AMID contributed a 5.56% ownership interest in OGL to D-Day. This transaction
resulted in the Company holding 27.93% of the Class A membership units of OGL as of September 29, 2017.

Opinion on the Financial Statements

We have audited the accompanying balance  sheets of Delta House Oil and Gas Lateral,  LLC (the “Company”) as of December  31, 2017 and 2016, the related
statements of operations, changes in members’ equity, and cash flows for each of the three years in the period ended December 31, 2017, 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 at December 31, 2017 and 2016, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2017, in
conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

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

We conducted our audits in accordance with the standards of the PCAOB and in accordance with auditing standards generally accepted in the United States of
America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material
misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements,
whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the
amounts  and  disclosures  in  the  financial  statements.  Our  audits  also  included  evaluating  the  accounting  principles  used  and  significant  estimates  made  by
management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

DELTA HOUSE OIL AND GAS LATERAL, LLC

Exhibit 99.2

Notes to Financial Statements

(Dollar Amounts in Thousands)

1. Organization and Nature of Operations

Delta House Oil and Gas Lateral, LLC (the “Company”) was formed in the state of Delaware as a limited liability company on October 18, 2012.  The Company
will  continue  in  existence  until  it  is  dissolved  and  terminated  by  the  members  of  the  Company  in  accordance  with  the  provisions  of  the  Limited  Liability
Agreement (the “LLC Agreement” or “Operating Agreement”). The Company was formed to finance, design, construct, and own and operate oil and natural gas
lateral transportation facilities (the “Facilities”), which receive and transport production of hydrocarbons from the Marmalard, Neidermeyer, and SOB 2 prospects
(the “Anchor Prospects”), the Blue Wing Olive, Malachite, and SOB III prospects (the “Secondary Prospects”), and the Otis, Odd Job, LaFemme, and Red Zinger
prospects (the “Additional Priority Prospects”) in the Gulf of Mexico and any future additional prospects from a floating production platform (the “Base FPS”)
developed by Delta House FPS, LLC, to commercial pipeline operators.  The planned capacity of the Facilities is 100,000 barrels of oil per day and 240 MMCF of
natural gas per day.

The Base FPS and the Facilities commenced operations in April 2015.

On December 6, 2012, the Company entered into agreements with the producers (the “Producers”) of the Anchor Prospects and the Secondary Prospects, and then
subsequently of the Additional Priority Prospects, to provide oil and natural gas transportation services (collectively, the “Transportation Agreements”). On June
30, 2017, the Company entered into agreements with the Producers of subsequent Additional Priority Prospects. The Producers have agreed to pay the Company a
variable fee for each barrel of oil and MMBtu of natural gas produced and delivered to the Base FPS. Additionally, the Producers are contractually obligated to pay
a fixed monthly fee of $925 for oil and $943 for natural gas for the right to use the Facilities. The fixed fees terminate seven (7) years from the date all Anchor
Prospects had delivered first production to the FPS, which occurred on August 1, 2015.

Profits and losses are allocated to the members in proportion to their equity percentage interests, with certain restrictions dictated by specific terms under the LLC
Agreement.

2. Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation

The financial statements have been prepared in U.S. dollars using accounting principles generally accepted in the United States ("GAAP").

Cash and Cash Equivalents

Cash and cash equivalents represent cash and short-term, highly liquid investments, with original maturities of three months or less. The cash equivalents as of
December 31, 2017 and 2016 consisted of a money market account.

Restricted Cash

The Company maintains restricted cash for future decommissioning obligations, and has collected and recorded $806 and $463 of long-term restricted cash as of
December 31, 2017 and 2016, respectively.

Accounts Receivable - Related Parties

Receivables from the sale of oil and natural gas transportation services are unsecured. All accounts receivable are from the Producers, who are members of the
Company.  Allowance  for  doubtful  accounts  are  determined  based  on  management’s  assessment  of  the  creditworthiness  of  the  customer.  Past  due  accounts  are
written  off  against  the  allowance  for  doubtful  accounts  only  after  all  collection  attempts  have  been  exhausted.  At  December  31,  2017  and  2016,  management
believed that all balances from customers were fully collectible such that no allowance for doubtful accounts was deemed necessary.

DELTA HOUSE OIL AND GAS LATERAL, LLC

Exhibit 99.2

Notes to Financial Statements

(Dollar Amounts in Thousands)

Revenue Recognition

Revenue from our oil and natural gas export offshore pipelines is based on a fixed monthly fee through July 2022 for the right to use the Facilities and a fixed fee
per unit of volume gathered or transported multiplied by the volume delivered. Transportation fees are based on contractual arrangements.  Revenue associated
with the fixed monthly fees are recognized over the contract period and the fixed fees per unit of volume are recognized when volumes have been delivered.

Differences in the amounts invoiced and revenue recognized is recorded as deferred revenue on the balance sheet.

The  Company  recognizes  a  decommissioning  fee  for  each  barrel  of  oil  equivalent  processed  and  has  recorded  $328,  $314  and  $194  of  decommissioning  fee
revenue during the years ended December 31, 2017, 2016 and 2015, respectively.

Fair Value of Financial Instruments

The  Company’s  financial  instruments  consist  of  cash  and  cash  equivalents,  restricted  cash,  accounts  receivable,  and  accounts  payable.  The  carrying  amounts
approximate fair value due to the short-term nature of these instruments.

Property and Equipment

Property and equipment are recorded at cost. Betterments are capitalized. Repair and maintenance costs are expensed as incurred. Property and equipment consists
of the following:

The  estimated  useful  lives  of  the  Facilities  are  revised  when  circumstances  or  events  indicate  that  the  overall  life  of  the  Facilities  differs  from  the  previous
estimate. In the fourth quarter of 2016 the useful lives were revised from 40 years to 27 years based on changes in the estimated production life of the oil and
natural  gas reserves  on which the Facilities  are dependent. Changes in estimated  useful lives are accounted  for prospectively from the date of the revision as a
change in accounting estimate.

Depreciation  expense  is  computed  using  the  straight-line  method  over  the  estimated  useful  lives  of  the  assets,  net  of  any  salvage  value.  Depreciation  expense
during the years ended December 31, 2017, 2016 and 2015 was $6,215, $4,884 and $3,162, respectively.

The recoverability of long-lived assets are evaluated when events or changes in circumstances indicate that the carrying amount of the long-lived asset might not be
recoverable.  If such impairment  indicators  exist,  the  Company performs  a two-step  impairment  test.  First, the undiscounted  future  cash  flows of the long-lived
assets are estimated and compared to assets’ carrying value and, if the undiscounted cash flows are less than the carrying value, the assets are considered impaired.
Second, the impairment loss is measured by reducing the carrying value to the estimated fair value of the assets. No impairment losses were recorded during the
years ended December 31, 2017, 2016 and 2015.

Asset Retirement Obligations (“AROs”)

AROs are legal obligations associated with the removal and abandonment of tangible long-lived assets and are recognized in the period in which it is incurred, if a
reasonable estimate of fair value can be made. AROs are initially measured at their estimated fair values and recorded as liabilities with an increase as well to the
carrying amount of the related long-lived asset. In future periods subsequent to initial recognition, accretion of the liability is recognized each period and the asset
is depreciated using the straight-line method over its useful life. The Company recorded an ARO relating to the future dismantlement of the Facilities. A revision to
the estimate was recorded during the years ended December 31, 2017 and 2016 due to changes in the estimated costs to remove and abandon the assets. Accretion
expense during the years ended December 31, 2017, 2016 and 2015 was $15, $85 and $99, respectively.

The following table provides an analysis of changes in the ARO liability during the years ended December 31, 2017 and 2016:

When preparing  financial  statements  in conformity  with U.S. GAAP, management  must make estimates  and assumptions based on information  available  at the
time. These estimates and assumptions affect the reported amounts of assets, liabilities, revenues and expenses, as well as the disclosures of contingent assets and
liabilities as of the date of the financial statements. Estimates and assumptions are based on information available at the time such estimates and assumptions are
made. Adjustments made with respect to the use of these estimates and assumptions often relate to information not previously available. Uncertainties with respect
to such estimates and assumptions are inherent in the preparation of financial statements. Estimates and assumptions are used in, among other things i) analyzing
long-lived  assets  and  assets  for  possible  impairment,  ii)  estimating  the  useful  lives  of  assets,  and  iii)  estimating  the  inputs  required  in  calculating  the  asset
retirement obligations. Actual results could differ materially from estimated amounts.

Income Taxes

The Company files its federal income tax return as a limited liability corporation under the Internal Revenue Code. In lieu of corporate income taxes, the members
of the Company are taxed on their proportionate share of the Company’s taxable income. Accordingly, no provision or liability has been recognized for federal
income tax purposes in the accompanying financial statements, as taxes are the responsibility of the individual members of the Company.

The Company’s assets are located in federal waters in the Gulf of Mexico, and therefore, are not subject to state income taxes.

Each income tax position is assessed using a two-step process. A determination is first made as to whether it is more likely than not that the income tax position
will be sustained, based upon technical merits, upon examination by the taxing authorities. If the income tax position is expected to meet the more likely than not
criteria, the benefit recorded in the financial statements equals the largest amount that is greater than 50% likely to be realized upon its ultimate settlement. The
Company had no uncertain tax positions as of December 31, 2017 and 2016. During the years ended December 31, 2017, 2016 and 2015, the Company did not
incur any income tax-related interest or penalties.

DELTA HOUSE OIL AND GAS LATERAL, LLC

Exhibit 99.2

Notes to Financial Statements

(Dollar Amounts in Thousands)

None of the Company’s federal income tax returns are currently under examination by the Internal Revenue Service (“IRS”). However, fiscal years 2014 and later
remain subject to examination by the IRS.

Concentration of Credit Risk

The Company’s primary assets, which are located in the Gulf of Mexico, provide transportation services to producers of oil and natural gas from the Base FPS. The
Company has a concentration of accounts receivable balances due from companies engaged in the production of oil and natural gas in the Gulf of Mexico. These
customers may be similarly affected by changes in economic, regulatory, weather, or other factors.

The Company maintains cash and cash equivalents and restricted cash balances at financial institutions in the United States of America, which at times exceed
federally insured amounts. The Company has not experienced any losses in such accounts, and does not believe a significant concentration of credit risk exists with
its cash and cash equivalents.

Correction of an Error

During 2017, the Company identified a misstatement related to revenue for the fixed monthly transportation fees, which were being recognized as billed instead of
over  the  contract  period.    The  impact  on  prior  periods  was  not  material,  so  the  Company  has  corrected  the  misstatement  in  the  fourth  quarter  of  2017,  which
resulted in a decrease in revenue and net income of approximately $3 million representing the cumulative impact of the misstatement through September 30, 2017,
$1.7 million of which related to 2016 and prior.

Recent Accounting Pronouncements

In May 2014, the FASB issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”), which supersedes
nearly all existing revenue recognition guidance under GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are
transferred to customers in an amount that reflects the consideration to which an entity expects to be entitled for those goods or services. ASU 2014-09 defines a
five-step process to achieve this core principle and, in doing so, more judgment and estimates may be required within the revenue recognition process than are
required under existing GAAP. The Company has elected to adopt the standard in line with the required effective date of public entities. The guidance permits
using either of the following transition methods: (i) a full retrospective approach reflecting the application of the standard in each prior reporting period with the
option to elect certain practical expedients, or (ii) a retrospective approach with the cumulative effect of initially adopting ASU 2014-09 recognized at the date of
adoption  (which  includes  additional  footnote  disclosures).  Early  application  is  permitted.  The  Company  will  adopt  the  new  standard  effective  January  1,  2018,
using the modified retrospective approach. The adoption of ASU 2014-09 will not result in a cumulative adjustment to members’ equity on adoption. In addition, it
will not have a material impact on the Company’s consolidated financial position, results of operations, equity or cash flows, except for the recharacterization of
deferred revenue as a refund liability.

In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (a consensus of the Emerging Issues Task Force) .
The  ASU  intends  to  address  classification  and  presentation  of  changes  in  restricted  cash  on  the  statement  of  cash  flows.  The  standard  requires  an  entity’s
reconciliation of the beginning-of-period and end-of-period total amounts shown on the statement of cash flows to include in cash and cash equivalents amounts
generally described as restricted cash and restricted cash equivalents. The ASU does not define restricted cash or restricted cash equivalents, but an entity will need
to  disclose  the  nature  of  the  restrictions.  The  guidance  is  effective  for  public  entities  for  annual  and  interim  periods  beginning  after  December  15, 2017.  Early
adoption is permitted, including adoption in an interim period. If an entity early adopts the amendments in an interim period, adjustments should be reflected at the
beginning of the fiscal year that includes that interim period. Entities should apply this ASU using a retrospective transition method to each period presented. The
Company will adopt the new standard on its effective  date, January 1, 2018 and will include restricted  cash on the balance sheet to be included in cash on the
statement of cash flows and provide the additional disclosures.

3. Commitments and Contingencies

Legal Proceedings

The Company is not currently party to any pending litigation or governmental proceedings, other than ordinary routine litigation incidental to its business. While
the ultimate impact of any proceedings cannot be predicted with certainty, the Company believes that the resolution of any of its pending proceedings will not have
a material effect on its financial condition or results of operations.

Environmental Matters

The  Company  is  subject  to  federal  and  state  laws  and  regulations  relating  to  the  protection  of  the  environment.  Environmental  risk  is  inherent  to  processing
platform operations and oil and natural gas pipeline transportation, and it could, at times, be subject to environmental cleanup and enforcement actions. In October
2017,  an  oil  leak  occurred  in  the  Gulf  of  Mexico  due  to  a  fracture  in  a  flow  line  jumper  connected  to  the  Base  FPS,  and  as  a  precautionary  measure,  the
Neidermeyer wells were shut-in. The Company has been advised by the producers responsible for these wells, that the wells are expected to be shut-in until early to
mid-2018 while environmental cleanup efforts continue. The Company believes it is not responsible for the oil leak nor is it liable for any costs associated with the
oil leak. As such, no liability has been recorded relating to this matter. The Company is not aware of any other material environmental matters.

4. Related Party Transactions

Transportation Agreements

The Company entered into separate Transportation Agreements with the Producers. Under the terms of the Transportation Agreements, the Company agreed to
construct, install, and decommission the Facilities that accepts dedicated production from the Anchor Prospects and Additional Priority Prospects at the Base FPS
in  the  Gulf  of  Mexico,  and  deliver  the  production  to  pipeline  operators.  In  addition,  the  Company  ensures  that  LLOG  Exploration  Offshore,  LLC  (“LLOG”)
operates the Company’s Facilities according to the project agreements. The Producers currently hold Class A Units in the Company.

The Company billed the Producers all the transportation and decommissioning fees for services performed during the years ended December 31, 2017, 2016 and
2015. As of December 31, 2017 and 2016, the Company had total receivables of $8,237 and $11,790, respectively, due from the Producers.

Asset Management Agreement

Consolidated Asset Management Services (Texas), LLC (“CAMS”) provides construction and asset management services to the Company under the terms of an
Asset Management Agreement (“AMA”). CAMS is indirectly owned by Tessa Group, LLC, a general partner holding a 60% partnership interest in CAMS, and
ArcLight Asset Management, LLC, a limited partner which (i) holds a 40% partnership interest in CAMS and (ii) is an affiliate of ArcLight Capital Partners, LLC
(“ArcLight”). At December 31, 2017, private equity funds under management by ArcLight hold an effective 23.3% of the Class A units in the Company through its
subsidiaries, Otter Offshore Holdings, LLC and Pinto Offshore Holdings, LLC.

The AMA will continue to be automatically renewed for successive periods of one (1) year each until an extension decline occurs. CAMS is paid a fixed monthly
fee and recovers the expenses it incurs under the AMA.

During the years ended December 31, 2017, 2016 and 2015, the Company incurred costs of $225, $225 and $225, respectively, related to the AMA, of which $0,
$0 and $94 was capitalized, respectively, and the remainder was included in general and administrative expense on the statements of operations, respectively.

As of December 31, 2017 and 2016, the Company had accounts payable due to CAMS of $19 and $19, respectively.

5. Members’ Equity

There are four classes of equity units as established by the LLC Agreement:

•
•
•
•

Class A units - a class of capital interests in respect of construction and operation of the Facilities
Class B units - a class of capital interests in respect of construction cost overruns with respect to the Facilities
Class C units - a class of capital interests in respect of expansions to the Facilities
Class D units - a class of capital interests in respect of unreimbursed major expenditures related to the Facilities

Class  B,  C,  and  D  units  have  no  voting  rights.  Distributions  to  members  holding  each  class  of  equity  units  are  subject  to  waterfall  provisions  contained  in  the
operating agreement.

For purposes of adjusting the capital accounts of the members, the net profits, net losses, and, to the extent necessary, individual items of income, gain, loss and
deduction,  for  any  fiscal  year  or  other  period,  shall  be  allocated  among  the  members  in  a  manner  such  that  the  adjusted  capital  account  of  each  member,
immediately  after  making  such  allocation,  is,  as  nearly  as  possible,  equal  (proportionately)  to  then  distributions  that  would  be  made  to  such  member,  if  the
Company were dissolved, its affairs wound up, and its properties sold for cash equal to their gross asset values, all Company liabilities were satisfied (limited with
respect to each nonrecourse liability to the gross asset value of the asset securing such liability), and the net assets of the Company were distributed to the members
immediately after making such allocation.

During the year ended December 31, 2015, $24,287 of Class A capital contributions were made by the members.  No contributions were made during the years
ended December 31, 2017 and 2016.

During the years ended December 31, 2017, 2016 and 2015, the Company paid distributions totaling $72,480, $66,148 and $20,432, respectively, to the members
of Class A units.

6. Subsequent Events

The Company has evaluated subsequent events through March 14, 2018, which is the date these financial statements were available for issuance.

On January 31, 2018 and February 28, 2018, the Company paid distributions of $4,178 and $3,945, respectively, to the members of Class A units.

We  have  audited  the  accompanying  balance  sheets  of  Delta  House  FPS,  LLC  (the  “Company”)  as  of  December  31,  2017  and  2016,  the  related  statements  of
operations,  changes  in members’  equity,  and cash  flows for  each  of the three  years  in the period  ended December  31, 2017, 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 at
December 31, 2017 and 2016, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2017, in conformity
with accounting principles generally accepted in the United States of America.

Basis for Opinion

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

We conducted our audits in accordance with the standards of the PCAOB and in accordance with auditing standards generally accepted in the United States of
America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material
misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements,
whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the
amounts  and  disclosures  in  the  financial  statements.  Our  audits  also  included  evaluating  the  accounting  principles  used  and  significant  estimates  made  by
management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Notes to Financial Statements

(Dollar Amounts In Thousands)

Exhibit 99.3

1. Organization and Nature of Operations

Delta House FPS, LLC (the “Company”) was formed in the state of Delaware as a limited liability company on October 18, 2012. The Company is to continue in
existence until it is dissolved and terminated by the members of the Company in accordance with the provisions of the Amended and Restated Limited Liability
Company Operating Agreement (the “LLC Agreement” or “Operating Agreement”). The Company was formed to finance, design, construct, and own and operate
a floating production system (“Base FPS”) for use in the Gulf of Mexico. The planned capacity of the Base FPS is 80,000 barrels of oil per day, 200 MMCF of
natural gas per day, and 40,000 barrels of water per day. The oil lateral facilities attached to the Base FPS have a planned capacity of 100,000 barrels of oil per day.
The natural gas lateral facilities attached to the Base FPS have a planned capacity of 240 MMCF of natural gas per day.

The Base FPS became operational in April 2015.

On December  6,  2012, the  Company  entered  into  agreements  with  the  producers  (the  “Producers”)  of  the  Marmalard,  Neidermeyer,  and  SOB II  prospects  (the
“Anchor Prospects”), Blue Wing Olive, Malachite, and SOB III prospects (the “Secondary Prospects”), and Otis and Odd Job prospects (the “Additional Priority
Prospects”) in the Gulf of Mexico for the use of the Company’s Base FPS.  On June 30, 2017, the Company entered into agreements with the Producers of the
LaFemme and Red Zinger prospects, both of which are deemed to be Additional Priority Prospects. The Producers have agreed to pay the Company a production
handling fee based on the oil, natural gas, and condensate produced and processed by the Base FPS.  In the event of a suspension of production, the Producers are
contractually  obligated  to pay a suspension  fee as defined  in the processing  agreement.   The Producers  will also pay a decommissioning fee on the production
processed through the facility, which will be used to fund the decommissioning and abandonment costs of the Base FPS.

Profits and losses are allocated to the members in proportion to their equity percentage interests, with certain restrictions dictated by specific terms under the LLC
Agreement.

2. Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation

The financial statements have been prepared in U.S. dollars using accounting principles generally accepted in the United States ("GAAP").

Cash and Cash Equivalents

Cash and cash equivalents represent cash and short-term, highly liquid investments, with original maturities of three months or less. The cash equivalents as of
December 31, 2017 and 2016 consisted of a money market account.

Restricted Cash

The  Company  is  required  under  the  terms  of  its  credit  agreement  to  maintain  restricted  cash  deposits  for  construction,  revenue  receipts,  debt  service,
decommissioning, operating expenses, and loss proceeds.

Fair Value of Financial Instruments

The Company’s financial instruments consist of cash and cash equivalents, restricted cash, accounts receivable, accounts payable, debt, and derivative assets and
liabilities. See Notes 4 and 5 regarding the fair value of derivative assets and liabilities. The carrying amounts of the other financial instruments approximate fair
value due to the short-term nature of these instruments or market rates of interest.

Exhibit 99.3

Accounts Receivable - Related Parties

Receivables  from  the  processing  of  oil  and  natural  gas  are  unsecured.  All  accounts  receivable  are  from  the  Producers  who  are  members  of  the  Company.
Allowance  for  doubtful  accounts  are  determined  based  on  management’s  assessment  of  the  creditworthiness  of  the  customer.  Past  due  accounts  are  written  off
against the allowance for doubtful accounts only after all collection attempts have been exhausted. At December 31, 2017 and 2016, management believed that all
balances from customers were fully collectible such that no allowance for doubtful accounts was deemed necessary.

Property and Equipment

Property  and  equipment  are  recorded  at  cost.  Betterments  are  capitalized.  Repair  and  maintenance  costs  are  expensed  as  incurred.  Property  and  equipment
consisted of the following:

The estimated useful lives of the Base FPS is revised when circumstances or events indicate that the overall life of the Base FPS differs from the previous estimate.
In the fourth quarter of 2016 the useful lives were revised from 40 years to 27 years based on changes in the estimated production life of the oil and natural gas
reserves  on  which  the  Base  FPS  is  dependent.  Changes  in  estimated  useful  lives  are  accounted  for  prospectively  from  the  date  of  the  revision  as  a  change  in
accounting estimate.

Depreciation  expense  is  computed  using  the  straight-line  method  over  the  estimated  useful  lives  of  the  assets,  net  of  any  salvage  value.  Depreciation  expense
during the years ended December 31, 2017, 2016 and 2015 was $23,693, $18,552 and $11,906, respectively.

The recoverability of long-lived assets are evaluated when events or changes in circumstances indicate that the carrying amount of the long-lived asset might not be
recoverable.  If such impairment  indicators  exist,  the  Company performs  a two-step  impairment  test.  First, the undiscounted  future  cash  flows of the long-lived
assets  are  estimated  and  compared  to  the  assets’  carrying  value,  and,  if  the  undiscounted  cash  flows  are  less  than  the  carrying  value,  the  assets  are  considered
impaired. Second, the impairment loss is measured by reducing the carrying value to the estimated fair value of the assets. No impairment losses were recorded
during the years ended December 31, 2017, 2016 and 2015.

Asset Retirement Obligations (“AROs”)

AROs are legal obligations associated with the removal and abandonment of tangible long-lived assets and are recognized in the period in which it is incurred, if a
reasonable estimate of fair value can be made. AROs are initially measured at their estimated fair values and recorded as liabilities with an increase as well to the
carrying amount of the related long-lived asset. In future periods subsequent to initial recognition, accretion of the liability is recognized each period and the asset
is depreciated using the straight-line method over its useful life. The Company recorded an ARO for the dismantlement of the Base FPS. Revisions to the estimate
were recorded during the years ended December 31, 2017 and 2016 due to changes in the estimated costs to remove

The Producers will pay the Company (i) a production handling fee per barrel of oil equivalent (“BOE”), which is tiered, and which will decrease throughout the
term  of  the  contract,  based  on  delivery  of  specific  levels  of  production  to  the  FPS,  (ii)  a  suspension  fee  if  targeted  capacity  levels  are  not  met,  and  (iii)  a
decommissioning fee, which will be used to fund the decommissioning and abandonment of the Base FPS. All costs relating to the operation of the facility are the
obligation of the Producers, with the exception of certain excluded costs.

As a result of the tiered fee structure, the Company recognizes revenue from the production handling fees based on the estimated average production handling fee
and  the  production  handled  during  the  period  from  each  prospect.  The  estimated  average  production  handling  fee  is  determined  as  the  estimated  remaining
expected fees divided by the estimated future production (risk-adjusted proved, probable and possible reserves) from the Anchor Prospects, Secondary Prospects,
and Additional Priority Prospects.

Production handling fees billed in excess of revenue recognized are recorded as deferred revenue. At December 31, 2017 and 2016, deferred revenue related to the
production handling fees was $413,460 and $423,040, respectively.

The Company bills the Producers a suspension fee when a "suspension event" occurs. A suspension event is considered to occur if prior to FPS owner-payout on a
rolling 30-day production from any Anchor prospect ceases or is suspended for a period of at least 336 hours and the total processing fees for that month for all
production, including any production from third party prospects, delivered to the FPS are less than the suspension fee. The suspension fee paid by the Producers of
the prospects is determined  as one-twelfth  of eight (8) percent  of the amount required  to achieve  FPS owner-payout. No suspension fees were earned or billed
during the years ended December 31, 2017, 2016 and 2015.

The Company invoices the Producers a decommissioning fee for each BOE processed. The decommissioning fee per BOE processed is determined based on the
estimated future decommissioning costs for the Base FPS and the estimated future production. Within 90 days of the date of last sustainable production from the
Anchor Prospects and Additional Priority Prospects, the Company may elect to (i) abandon and remove the Base FPS using the decommissioning fees collected
from  the  Producers,  (ii)  retain  ownership  of  the  Base  FPS  and  assume  the  obligation  of  the  abandonment  and  removal  costs,  including  refunding  the
decommissioning fees collected from the Producers, or (iii) delay provisionally for a further 90 days its determination to abandon and remove or retain ownership
of the Base FPS. At the current time it is uncertain which election will be taken by the Company. Due to the significant length of time before the removal and
abandonment costs are expected to occur, the decommissioning fees are recorded as long-term accounts receivable and long-term deferred revenue when billed.
Cash collected on the fees are recorded as long-term restricted cash. The Company has billed $2,144, $1,286 and $409 of decommissioning fees during the years
ended December 31, 2017, 2016 and 2015, and has collected and recorded long-term restricted  cash of $2,070 and $1,133 as of December 31, 2017 and 2016,
respectively, for future decommissioning costs.

Operating Costs

The Base FPS is operated by LLOG Exploration Offshore, LLC (”LLOG”) on behalf of the Producers (See Note 6). With the exception of certain excluded costs,
LLOG initially pays and discharges all necessary and reasonable costs incurred in connection

with the performance, operation, repair, and maintenance activities of the Base FPS.  LLOG receives reimbursements of costs incurred from the Producers under
Production Handling and Floating Production System Use Agreements (“Production Agreements”) (See Note 6). LLOG allocates the Base FPS costs and related
overhead among the producers in accordance with the applicable provisions of the Production Agreements.

Use of Estimates

When preparing  financial  statements  in conformity  with U.S. GAAP, management  must make estimates  and assumptions based on information  available  at the
time. These estimates and assumptions affect the reported amounts of assets, liabilities, revenues and expenses, as well as the disclosures of contingent assets and
liabilities as of the date of the financial statements. Estimates and assumptions are based on information available at the time such estimates and assumptions are
made. Adjustments made with respect to the use of these estimates and assumptions often relate to information not previously available. Uncertainties with respect
to such estimates and assumptions are inherent in the preparation of financial statements. Estimates and assumptions are used in, among other things i) developing
fair value estimates, including assumptions for future cash flows and discount rates, for the interest rate swap derivative valuations, ii) analyzing long-lived assets
for  possible  impairment,  iii)  estimating  the  useful  lives  of  assets,  iv)  estimating  the  inputs  required  in  calculating  the  asset  retirement  obligations,  and  v)
determining the estimated average
production handling fee rates using third-party oil and natural gas reserve estimates for revenue recognition purposes. Actual results could differ materially from
estimated amounts.

Concentration of Credit Risk

Financial  instruments,  which  potentially  subject  the  Company  to  concentrations  of  credit  risk,  consist  principally  of  cash  and  cash  equivalents,  restricted  cash,
accounts receivable - related party, and derivative instruments.

Cash and cash equivalents and restricted cash include investments in money market securities and securities backed by the U.S. government. The Company’s cash
accounts, which at times exceed federally insured limits, are held by major financial institutions. The Company believes that no significant concentration of credit
risk exists with respect to cash and cash equivalents or its derivative instruments.

The  Company  has  concentrations  of  credit  risk  from  its  sources  of  revenue  and  accounts  receivable  due  to  the  limited  geographic  area  in  which  the  Company
operates and its single revenue generating asset. The Base FPS, which is located in the Gulf of Mexico, provides processing capacity that links producers of oil,
natural gas, liquids, and condensate, to onshore markets in the region. The Company has a concentration of accounts receivable balances due from the Producers
engaged in the production of oil and natural gas in the Gulf of Mexico through the Base FPS. These customers may be similarly affected by changes in economic,
regulatory, weather, or other factors.

Debt Issuance Costs

Debt issuance costs are recorded as a reduction of the related long-term debt and amortized over the term of the debt. The Company incurred debt issuance costs of
$14,983 in connection with the credit facility entered into on June 20, 2014. Amortization related to debt issuance costs totaled $6,527, $2,000 and $1,997 during
the  years  ended  December  31,  2017,  2016  and  2015,  respectively.  Amortization  of  debt  issuance  costs  is  included  in  interest  expense  except  for  $582  of  debt
issuance costs which were capitalized during the year ended December 31, 2015 prior to the Base FPS being placed into service. During the year ended December
31, 2017, the Company changed its estimate of the credit facility’s life and amortized an additional $4,527 of debt issuance costs, which is included in the amount
above, to be in line with the anticipated payoff date of the credit facility. At December 31, 2017, the Company had $3,303 of deferred debt issuance costs, which
have been classified as a reduction of the current portion of long-term debt. At December 31, 2016, the Company had $9,830 of deferred debt issuance costs, which
have been classified as a reduction of long-term debt.

Exhibit 99.3

Income Taxes

The Company files its federal income tax return as a limited liability corporation under the Internal Revenue Code. In lieu of corporate income taxes, the members
of the Company are taxed on their proportionate share of the Company’s taxable income. Accordingly, no provision or liability has been recognized for federal
income tax purposes in the accompanying financial statements, as taxes are the responsibility of the individual members of the Company.

The Base FPS operates in federal waters in the Gulf of Mexico, and is therefore not subject to state income tax.

Each income tax position is assessed using a two-step process. A determination is first made as to whether it is more likely than not that the income tax position
will be sustained, based upon technical merits, upon examination by the taxing authorities. If the income tax position is expected to meet the more likely than not
criteria, the benefit recorded in the financial statements equals the largest amount that is greater than 50% likely to be realized upon its ultimate settlement. The
Company  includes  tax-related  interest  and  penalties  in  income  tax  expense.  The  Company  had  no  uncertain  tax  positions  as  of  December  31,  2017  and  2016.
During the years ended December 31, 2017, 2016 and 2015, the Company did not incur any income tax-related interest or penalties.

None of the Company’s federal income tax returns are currently under examination by the Internal Revenue Service (“IRS”). However, fiscal years 2014 and later
remain subject to examination by the IRS.

Derivative Financial Instruments

Financial derivatives are used as part of the Company’s overall risk management strategy in order to reduce the effects of interest rate fluctuations on its variable
interest rate debt.

The Company has not designated any of its derivative contracts as accounting hedges, and therefore, all of the derivative instruments are being marked-to-market
on the balance sheets, with changes in fair value recorded in the statements of operations.

Although the counterparties provide no collateral, the derivative agreements with each counterparty allow the Company, so long as it is not a defaulting party, after
a default or the occurrence of a termination event, to set-off an unpaid derivative agreement receivable against the interest of the counterparty in any outstanding
balance under the credit facility. If a counterparty were to default in payment of an obligation under the derivative agreements, the Company could be exposed to
interest rate fluctuations.

Recent Accounting Pronouncements

In May 2014, the FASB issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”), which supersedes
nearly all existing revenue recognition guidance under GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are
transferred to customers in an amount that reflects the consideration to which an entity expects to be entitled for those goods or services. ASU 2014-09 defines a
five-step process to achieve this core principle and, in doing so, more judgment and estimates may be required within the revenue recognition process than are
required under existing GAAP. The Company has elected to adopt the standard in line with the required effective date of public entities. The guidance permits
using either of the following transition methods: (i) a full retrospective approach reflecting the application of the standard in each prior reporting period with the
option to elect certain practical expedients, or (ii) a retrospective approach with the cumulative effect of initially adopting ASU 2014-09 recognized at the date of
adoption  (which  includes  additional  footnote  disclosures).  Early  application  is  permitted.  The  Company  will  adopt  the  new  standard  effective  January  1,  2018,
using the modified retrospective approach. The adoption of ASU 2014-09 will not result in a cumulative adjustment to members’ equity on adoption. In addition, it
will not have a material impact on the Company’s consolidated financial position, results of operations, equity or cash flows, except for the recharacterization of
deferred revenue as a refund liability.

In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (a consensus of the Emerging Issues Task Force) .
The ASU intends to address classification and presentation of changes in restricted cash on the

12

 
 
 
 
DELTA HOUSE FPS, LLC

Notes to Financial Statements

(Dollar Amounts In Thousands)

Exhibit 99.3

statement of cash flows. The standard requires an entity’s reconciliation of the beginning-of-period and end-of-period total amounts shown on the statement of cash
flows to include in cash and cash equivalents amounts generally described as restricted cash and

restricted cash equivalents. The ASU does not define restricted cash or restricted cash equivalents, but an entity will need to disclose the nature of the restrictions.
The guidance is effective for public entities for annual and interim periods beginning after December 15, 2017. Early adoption is permitted, including adoption in
an interim period. If an entity early adopts the amendments in an interim period, adjustments should be reflected at the beginning of the fiscal year that includes
that interim period. Entities should apply this ASU using a retrospective transition method to each period presented. The Company will adopt the new standard on
its  effective  date,  January  1,  2018  and  will  include  restricted  cash  on  the  balance  sheet  to  be  included  in  cash  on  the  statement  of  cash  flows  and  provide  the
additional disclosures.

3. Debt

On June 20, 2014, the Company entered into a $400 million credit facility with a consortium of banks to issue term construction loans of $333 million, with a
maturity date of September 20, 2021, and issue letters of credit of $67 million supporting the Company’s debt service reserve obligations.  The Company has made
principal payments beyond the scheduled amortization  set forth by the banks, to the point at which the term loans will be repaid during 2018. The outstanding
balance of the term loans as of December 31, 2017 and 2016 was $36,449 and $124,514, net of debt issuance costs of $3,303 and $9,830, respectively.  The credit
facility bears interest at the applicable London Interbank Offered Rate plus a margin of 3.25% for the first three years, 3.5% for the next three years, and 3.75% for
the years thereafter, or an alternate margin computed based on the Prime Loan Rate plus applicable margins of 2.25% for the first three years, 2.5% for the next
three years, and 2.75% thereafter. As of December 31, 2017 and 2016, the Company’s interest rate was 4.85% and 3.86%, respectively.

The repayment schedule requires four payments per year through the maturity date of the credit facility.

The credit facility is secured by mortgages on the Company’s Base FPS.

The  Company  must  comply  with  various  restrictive  covenants  in  the  credit  agreement.    These  covenants  include,  among  others:  maintenance  of  insurance,
obtaining interest rate protection agreements, performance under the project documents, limitations on additional indebtedness, and restrictions on the declaration
or payment of dividends.  As of December 31, 2017 and 2016, the Company was in compliance with all of the restrictive covenants.

The future maturities under the credit facility as of December 31, 2017 were as follows:

On  June  1,  2016,  the  Company  entered  into  a  short-term  note  to  finance  its  excess  liability  insurance  policy.  The  note  has  an  11-month  term  and  an  annual
percentage rate of 3.49%. The final insurance payment was made during April 2017. The balances of the note as of December 31, 2017 and 2016 were $0 and
$223, respectively.

4. Derivative Instruments

The Company is exposed to interest rate risk through its long-term borrowings, which are variable interest rate instruments. In July 2014, the Company entered into
interest rate swap contracts, expiring through November 2018, under which the Company agreed to pay an amount equal to a specified fixed rate of interest times a
notional principal amount, and to receive in return, an amount equal to a specified variable rate of interest times the same notional principal amount. On May 31,
2016 and June 1, 2016, the Company amended existing interest rate swap agreements with its counterparties.  The amendments reduced the contract fixed interest
rates, changed the floating indexes from three to one month LIBOR and changed the settlement frequency from quarterly

to monthly.  The changes took effect as of the amendment dates and will impact the value of the swaps for the remainder of their terms.

The Company’s interest rate swaps as of December 31, 2017 and 2016, and related fair values, were as follows:

During the years ended December 31, 2017, 2016 and 2015, the Company recognized an unrealized gain on derivatives of $2, $934 and $496, respectively, which
is included as a loss on derivatives, net, in the Company’s statements of operations. During the years ended December 31, 2017, 2016 and 2015, the Company paid
cash settlements of $77, $1,358 and $2,275, respectively, to the counterparties. The Company capitalized $430 of those settlements as a component of interest cost
prior to the Base FPS being placed into service during the year ended December 31, 2015.

5. Fair Value Measurements

Fair value is based on the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the
measurement date.  The Company utilizes a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three broad
levels, which are described below:

Level 1 -
Level 2 -
Level 3 -

Quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities.
Observable prices that are based on inputs not quoted on active markets, but corroborated by market data .
Unobservable inputs are used when little or no market data is available. 

The following table sets forth, by the fair value hierarchy, the Company’s net financial assets and liabilities that are accounted for at fair value on a recurring basis
as of December 31, 2017 and 2016:

6. Related Party Transactions

Production Handling and Floating Production System Use Agreements

The  Company  entered  into  separate  production  handling  agreements  with  the  Producers  which  are  effective  for  an  initial  term  of  five  (5)  years  and  will  be
automatically extended for successive five (5)-year periods unless and until terminated by the Company or the Producers pursuant to the terms of the agreements. 
Termination  of the agreements  may  occur  i) at the end of the economic  life  of the reserves  of the prospects;  ii) upon the occurrence  of an event of default  (as
defined in the agreement); iii) any act of omission that constitutes gross negligence or willful misconduct; iv) by the Company, if after first commercial production,
there has been no production for two (2) years, and there are no then-current operations underway to re-establish production, or the aggregate production being
processed by the Base FPS is less than 2,000 BOE per day for 180 consecutive days; v) if damage to the Base FPS renders the Base FPS an actual or constructive
loss; vi) if maintenance or repair, or a change mandated by a government

authority to the Base FPS requires major work and the Producers decline to become a participating producer; or vii) by the Company, if a suspension period for a
producer does not terminate by July 31, 2018.

The Producers currently hold Class A Units in the Company. Under the Production Agreements, the Company agreed to construct and decommission the Base FPS
that accepts dedicated production from the Anchor Prospects, Secondary Prospects, and the Additional Priority Prospects, which then processes the production and
delivers comingled processed oil, natural gas, and condensate to the oil and natural gas laterals, which connect to pipelines transporting the oil, natural gas, and
condensate to shore. In addition, the Company ensures that LLOG operates the Base FPS according to the project agreements.

The Company billed  the  Producers  a total  of $166,860, $428,457 and  $268,876 for production  handling  fees  and decommissioning  fees  for services  performed
during the years ended December 31, 2017, 2016 and 2015 , respectively. As of December 31, 2017 and 2016 , the Company had total receivables of $17,531 and
$44,660, respectively, due from the Producers.

Asset Management Agreement

Consolidated Asset Management Services (Texas), LLC (“CAMS”), provides construction and asset management services to the Company under the terms of an
Asset Management Agreement (“AMA”). CAMS is indirectly owned by Tessa Group, LLC, a general partner holding a 60% partnership interest in CAMS and
ArcLight Asset Management, LLC, a limited partner which (i) holds a 40% partnership interest in CAMS and (ii) is an affiliate of ArcLight Capital Partners, LLC
(“ArcLight”). At December

(Dollar Amounts In Thousands)

Exhibit 99.3

31,  2017,  private  equity  funds  under  management  by  ArcLight  hold  an  effective  23.3%  interest  in  the  Company’s  Class  A  units  through  its  subsidiaries  Stork
Offshore Holdings, LLC and Pinto Offshore Holdings, LLC.

The AMA will continue to be automatically renewed for successive periods of one (1) year each until an extension decline occurs. CAMS is paid a fixed monthly
fee and recovers the expenses it incurs under the AMA.

During the years ended December 31, 2017, 2016 and 2015, the Company incurred costs of $225, $225 and $225, respectively, related to the AMA, of which $0,
$0 and $66, respectively, were capitalized as costs related to the Base FPS.

As of December 31, 2017 and 2016, the Company had accounts payable due to CAMS of $19 and $19, respectively.

7. Commitments and Contingencies

Legal Proceedings

The Company is not currently party to any pending litigation or governmental proceedings, other than ordinary routine litigation incidental to its business. While
the ultimate impact of any proceedings cannot be predicted with certainty, the Company believes that the resolution of any of its pending proceedings will not have
a material effect on its financial condition or results of operations.

Environmental Matters

The  Company  is  subject  to  federal  and  state  laws  and  regulations  relating  to  the  protection  of  the  environment.  Environmental  risk  is  inherent  to  processing
platform  operations,  and  it  could,  at  times,  be  subject  to  environmental  cleanup  and  enforcement  actions.  In  October  2017,  an  oil  leak  occurred  in  the  Gulf  of
Mexico due to a fracture in a flow line jumper connected to the Base FPS, and as a precautionary measure, the Neidermeyer wells were shut-in. The Company has
been advised by the producers responsible for these wells, that the wells are expected to be shut-in until early to mid-2018 while environmental cleanup efforts
continue.  The  Company  believes  it  is  not  responsible  for  the  oil  leak  nor  is  it  liable  for  any  costs  associated  with  the  oil  leak.  As  such,  no  liability  has  been
recorded relating to this matter. The Company is not aware of any other material environmental matters.

8. Members’ Equity

There are four classes of equity units established by the LLC Agreement:

•
•
•
•

Class A Units - a class of capital interests in respect of construction and operation of the Base FPS
Class B Units - a class of capital interests in respect of construction cost overruns with respect to the Base FPS
Class C Units - a class of capital interests in respect of expansions to the Base FPS
Class D Units - a class of capital interests in respect of unreimbursed major expenditures related to the Base FPS

Class B, C and D units have no voting rights. Distributions to members holding each class of equity units are subject to waterfall provisions contained in the LLC
Agreement.

For purposes of adjusting the capital accounts of the members, the net profits, net losses, and to the extent necessary, individual items of income, gain, loss, and
deduction,  for  any  fiscal  year,  or  other  period,  shall  be  allocated  among  the  members  in  a  manner  such  that  the  adjusted  capital  account  of  each  member,
immediately  after  making  such  allocation,  is,  as  nearly  as  possible,  equal  (proportionately)  to  then  distributions  that  would  be  made  to  such  member  if  the
Company were dissolved, its affairs wound up, and its properties sold for cash equal to their gross asset values, all Company liabilities were satisfied (limited with
respect to each nonrecourse liability to the gross asset value of the asset securing such liability), and the net assets of the Company were distributed to the members
immediately after making such allocation.
