Overview



We are a publicly traded limited partnership with a diverse set of operations
focused primarily in the U.S. Gulf Coast region. Our four primary business lines
include:

• Terminalling, processing, storage and packaging services for petroleum


       products and by-products including the refining of naphthenic crude oil;



•      Land and marine transportation services for petroleum products and
       by-products, chemicals, and specialty products;


• Sulfur and sulfur-based products processing, manufacturing, marketing, and


       distribution; and



• NGL marketing, distribution, and transportation services.





The petroleum products and by-products we collect, transport, store and market
are produced primarily by major and independent oil and gas companies who often
turn to third parties, such as us, for the transportation and disposition of
these products. In addition to these major and independent oil and gas
companies, our primary customers include independent refiners, large chemical
companies, and other wholesale purchasers of these products. We operate
primarily in the U.S. Gulf Coast region. This region is a major hub for
petroleum refining, natural gas gathering and processing, and support services
for the exploration and production industry.

We were formed in 2002 by Martin Resource Management Corporation, a
privately-held company whose initial predecessor was incorporated in 1951 as a
supplier of products and services to drilling rig contractors. Since then,
Martin Resource Management Corporation has expanded its operations through
acquisitions and internal expansion initiatives as its management identified and
capitalized on the needs of producers and purchasers of petroleum products and
by-products and other bulk liquids. Martin Resource Management Corporation is an
important supplier and customer of ours. As of December 31, 2019, Martin
Resource Management Corporation owned 15.7% of our total outstanding common
limited partner units. Furthermore, Martin Resource Management Corporation
controls MMGP, our general partner, by virtue of its 51% voting interest in
Holdings, the sole member of MMGP. MMGP owns a 2.0% general partner interest in
us and all of our incentive distribution rights. Martin Resource Management
Corporation directs our business operations through its ownership interests in
and control of our general partner.

Our Omnibus Agreement with Martin Resource Management Corporation governs, among
other things, potential competition and indemnification obligations among the
parties to the agreement, related party transactions, the provision of general
administration and support services by Martin Resource Management Corporation
and our use of certain of Martin Resource Management Corporation's trade names
and trademarks. Under the terms of the Omnibus Agreement, the employees of
Martin Resource Management Corporation are responsible for conducting our
business and operating our assets.

Martin Resource Management Corporation has operated our business since
2002. Martin Resource Management Corporation began operating our NGL business in
the 1950s and our sulfur business in the 1960s. It began our land transportation
business in the early 1980s and our marine transportation business in the late
1980s. It entered into our fertilizer and terminalling and storage businesses in
the early 1990s.


                                       45

--------------------------------------------------------------------------------

Beginning in 2018, we committed to strengthening our balance sheet through strategic initiatives aimed at reducing leverage by divesting non-core assets and businesses, creating the ability to focus on a streamlined corporate strategy and position the Partnership for growth.



The first set of initiatives was executed in 2018 with the divestiture of our
20% interest in West Texas LPG Pipeline Limited Partnership for $195.0 million
and the sale of a non-strategic terminal asset located in Nevada for $8.0
million. On January 1, 2019, we completed the next initiative with the
acquisition of Martin Transport, Inc. from Martin Resource Management
Corporation for $135.0 million, positioning us for cash flow growth. On July 1,
2019, we completed the sale of our natural gas storage assets for $215.0
million, which was an important piece of the Partnership's strategy to
strengthen the balance sheet and re-focus our operational expertise on the
refinery services industry. On August 12, 2019 we completed the sale of our East
Texas Pipeline for $17.5 million.

As a result of dispositions, offset by acquisitions, we were able to pay down
$300.5 million of outstanding debt while incurring only a slight reduction to
projected EBITDA. Consistent with our strategy of reducing leverage and
improving liquidity, on January 28, 2020, we announced a $0.75 per unit
reduction of our cash distribution on an annual basis, allowing us to retain
$29.2 million to continue to strengthen our balance sheet.

Critical Accounting Policies and Estimates



Our discussion and analysis of our financial condition and results of operations
are based on the historical consolidated financial statements included elsewhere
herein. We prepared these financial statements in conformity with United States
generally accepted accounting principles ("U.S. GAAP" or "GAAP"). The
preparation of these financial statements required us to make estimates and
assumptions that affect the reported amounts of assets and liabilities at the
dates of the financial statements and the reported amounts of revenues and
expenses during the reporting periods. We based our estimates on historical
experience and on various other assumptions we believe to be reasonable under
the circumstances. We routinely evaluate these estimates, utilizing historical
experience, consultation with experts and other methods we consider reasonable
in the particular circumstances. Our results may differ from these estimates,
and any effects on our business, financial position or results of operations
resulting from revisions to these estimates are recorded in the period in which
the facts that give rise to the revision become known. Changes in these
estimates could materially affect our financial position, results of operations
or cash flows. You should also read Note 2, "Significant Accounting Policies" in
Notes to Consolidated Financial Statements. The following table evaluates the
potential impact of estimates utilized during the periods ended December 31,
2019 and 2018:

Our Relationship with Martin Resource Management Corporation

Martin Resource Management Corporation directs our business operations through
its ownership and control of our general partner and under the Omnibus
Agreement. In addition to the direct expenses payable to Martin Resource
Management Corporation under the Omnibus Agreement, we are required to reimburse
Martin Resource Management Corporation for indirect general and administrative
and corporate overhead expenses. For the years ended December 31, 2019, 2018 and
2017, the Conflicts Committee approved reimbursement amounts of $16.7 million,
$16.4 million and $16.4 million, respectively, reflecting our allocable share of
such expenses. The Conflicts Committee will review and approve future
adjustments in the reimbursement amount for indirect expenses, if any, annually.

We are required to reimburse Martin Resource Management Corporation for all
direct expenses it incurs or payments it makes on our behalf or in connection
with the operation of our business. Martin Resource Management Corporation also
licenses certain of its trademarks and trade names to us under the Omnibus
Agreement.

We are both an important supplier to and customer of Martin Resource Management
Corporation. All of these services and goods are purchased and sold pursuant to
the terms of a number of agreements between us and Martin Resource Management
Corporation. For a more comprehensive discussion concerning the Omnibus
Agreement and the other agreements that we have entered into with Martin
Resource Management Corporation, please see "Item 13. Certain Relationships and
Related Transactions, and Director Independence."

How We Evaluate Our Operations



Our management uses a variety of financial and operational measurements other
than our financial statements prepared in accordance with U.S. GAAP to analyze
our performance. These include: (1) net income before interest expense, income
tax expense, and depreciation and amortization ("EBITDA"), (2) adjusted EBITDA
and (3) distributable cash flow. Our management views these measures as
important performance measures of core profitability for our operations and the
ability to generate and distribute cash flow, and as key components of our
internal financial reporting. We believe investors benefit from having access to
the same financial measures that our management uses.

EBITDA and Adjusted EBITDA. Certain items excluded from EBITDA and adjusted
EBITDA are significant components in understanding and assessing an entity's
financial performance, such as cost of capital and historic costs of depreciable
assets. We have included information concerning EBITDA and adjusted EBITDA
because they provide investors and management with additional information to
better understand the following: financial performance of our assets without
regard to financing methods, capital structure or historical cost basis; our
operating performance and return on capital as compared to those of other
similarly situated entities; and the viability of acquisitions and capital
expenditure projects. Our method of computing adjusted EBITDA may not be the
same method used to compute similar measures reported by other entities. The
economic substance behind our use of adjusted EBITDA is to measure the ability
of our assets to generate cash sufficient to pay interest costs, support our
indebtedness and make distributions to our unit holders.

Distributable Cash Flow. Distributable cash flow is a significant performance
measure used by our management and by external users of our financial
statements, such as investors, commercial banks and research analysts, to
compare basic cash flows generated by us to the cash distributions we expect to
pay our unitholders. Distributable cash flow is also an important financial
measure for our unitholders since it serves as an indicator of our success in
providing a cash return on investment. Specifically, this financial measure
indicates to investors whether or not we are generating cash flow at a level
that can sustain or support an increase in our quarterly distribution rates.
Distributable cash flow is also a quantitative standard used throughout the
investment community with respect to publicly-traded partnerships because the
value of a unit of such an entity is generally determined by the unit's yield,
which in turn is based on the amount of cash distributions the entity pays to a
unitholder.

EBITDA, adjusted EBITDA and distributable cash flow should not be considered
alternatives to, or more meaningful than, net income, cash flows from operating
activities, or any other measure presented in accordance with U.S. GAAP. Our
method of computing these measures may not be the same method used to compute
similar measures reported by other entities.

Non-GAAP Financial Measures



The following table reconciles the non-GAAP financial measurements used by
management to our most directly comparable GAAP measures for the years ended
December 31, 2019, 2018, and 2017, which represents EBITDA, Adjusted EBITDA and
Distributable Cash Flow from continuing operations.

Results of Operations

--------------------------------------------------------------------------------

The results of operations for the years ended December 31, 2019, 2018, and 2017 have been derived from our consolidated financial statements.

We evaluate segment performance on the basis of operating income, which is derived by subtracting cost of products sold, operating expenses, selling, general and administrative expenses, and depreciation and amortization expense from revenues.



Our consolidated results of operations are presented on a comparative basis
below. There are certain items of income and expense which we do not allocate on
a segment basis. These items, including interest expense, and indirect selling,
general and administrative expenses, are discussed after the comparative
discussion of our results within each segment.

The Natural Gas Liquids segment information below excludes the discontinued operations of the Natural Gas Storage Assets and WTLPG partnership interests disposed of on June 28, 2019 and July 31, 2018, respectively, for the years ended December 31, 2019, 2018 and 2017. See Item 8, Note 5.

The following table sets forth our operating revenues and operating income by segment for the years ended December 31, 2019, 2018, and 2017.

Services revenues. Services revenue decreased $8.5 million, of which $5.2
million was primarily a result of decreased throughput fees at our shore-based
terminals combined with a $1.7 million decrease at our specialty terminals as a
result of the disposition of our sulfuric acid terminal in Elko, Nevada. In
addition, $1.6 million was a result of decreased activity at our Tampa specialty
terminal.

Products revenues. A 31% decrease in sales volumes combined with a 29% decrease
in average sales price at our shore-based terminals resulted in a $33.1 million
decrease to products revenues. Offsetting this decrease was a 10% increase in
sales volumes combined with a 3% increase in average sales price at our blending
and packaging facilities resulting in an $11.1 million increase in products
revenues.

Cost of products sold. A 31% decrease in sales volumes combined with a 32%
decrease in average cost per gallon at our shore-based terminals resulted in a
$31.7 million decrease in cost of products sold. Offsetting this decrease was a
10% increase in sales volume combined with a 1% increase in average cost per
gallon at our blending and packaging facilities resulting in a $7.4 million
increase in cost of products sold.

Operating expenses. Operating expenses decreased $0.9 million, of which $0.8
million is a result of the disposition of our sulfuric acid terminal in Elko,
Nevada combined with decreases in lease expense of $0.9 million and utilities of
$0.8 million across our terminals. Offsetting these decreases were increases in
repairs and maintenance of $1.2 million across our terminals and $0.5 million in
wharfage and dockage fees at our Tampa specialty terminal.

Selling, general and administrative expenses. Selling, general and administrative expenses increased primarily as a result of increases in legal expenses of $0.4 million and compensation expense of $0.3 million.

Depreciation and amortization. The decrease in depreciation and amortization is due to the disposition of assets at several closed shore-based facilities, offset by recent capital expenditures.

Indirect selling, general and administrative expenses remained consistent from 2018 to 2019. The increase in indirect selling, general and administrative expenses from 2017 to 2018 is primarily a result of increased unit based compensation expense.

Martin Resource Management Corporation allocates to us a portion of its indirect
selling, general and administrative expenses for services such as accounting,
treasury, clerical, engineering, legal, billing, information technology,
administration of insurance, general office expenses and employee benefit plans
and other general corporate overhead functions we share with Martin Resource
Management Corporation retained businesses. This allocation is based on the
percentage of time spent by Martin Resource Management Corporation personnel
that provide such centralized services. GAAP also permits other methods for
allocation of these expenses, such as basing the allocation on the percentage of
revenues contributed by a segment. The allocation of these expenses between
Martin Resource Management Corporation and us is subject to a number of
judgments and estimates, regardless of the method used. We can provide no
assurances that our method of allocation, in the past or in the future, is or
will be the most accurate or appropriate method of allocation for these
expenses. Other methods could result in a higher allocation of selling, general
and administrative expense to us, which would reduce our net income.

Under the Omnibus Agreement, we are required to reimburse Martin Resource
Management Corporation for indirect general and administrative and corporate
overhead expenses. The Conflicts Committee approved the following reimbursement
amounts:
                     Year Ended December 31,                    Percent     Year Ended December 31,                     Percent

The amounts reflected above represent our allocable share of such expenses. The Conflicts Committee will review and approve future adjustments in the reimbursement amount for indirect expenses, if any, annually.

Liquidity and Capital Resources

General



Our primary sources of liquidity to meet operating expenses, service our
indebtedness, pay distributions to our unitholders and fund capital expenditures
have historically been cash flows generated by our operations, borrowings under
our revolving credit facility and access to debt and equity capital markets,
both public and private. Set forth below is a description of our cash flows for
the periods indicated.

Recent Debt Financing Activity



Credit Facility Amendment and Extension. On July 18, 2019, the Partnership
amended its revolving credit facility to, among other things, extend the
maturity date from March 2020 to August 2023 (provided we have refinanced the
2021 Notes on or before August 19, 2020) and reduce commitments from $500.0
million to $400.0 million. After giving effect to our then current borrowings,
outstanding letters of credit and the financial covenants contained in our
revolving credit facility, we had the ability to borrow approximately $51.5
million in additional amounts thereunder as of December 31, 2019.

MTI.

Net cash used in financing activities. Net cash used in financing activities for the year ended December 31, 2019 decreased primarily as a result of $68.7 million decrease in net payments and a $29.3 million decrease in cash distributions paid.

--------------------------------------------------------------------------------

terminalling assets from Martin Resource Management Corporation in 2017,
compared to no acquisitions in 2018, resulted in an increase of $19.5 million.
Further, a decrease in cash used of $6.4 million is due to lower payments for
capital expenditures and plant turnaround costs in 2018. Offsetting was a $15.0
million decline in proceeds received resulting from repayment of the Note

2021 Senior Notes

We and Martin Midstream Finance Corp., a subsidiary of us (collectively, the
"Issuers"), entered into (i) an Indenture, dated as of February 11, 2013 (the
"2021 Indenture") among the Issuers, certain subsidiary guarantors (the "2021
Guarantors") and Wells Fargo Bank, National Association, as trustee (the "2021
Trustee") and (ii) a Registration Rights Agreement, dated as of February 11,
2013 (the "2021 Registration Rights Agreement"), among the Issuers, the 2021
Guarantors and Wells Fargo Securities, LLC, RBC Capital Markets, LLC, RBS
Securities Inc., SunTrust Robinson Humphrey, Inc. and Merrill Lynch, Pierce,
Fenner & Smith Incorporated, as representatives of a group of initial
purchasers, in connection with a private placement to eligible purchasers of
$250.0 million in aggregate principal amount of the Issuers' 7.25% senior
unsecured notes due 2021 (the "2021 Notes"). On April 1, 2014, we completed a
private placement add-on of $150.0 million of the 2021 Notes. In 2015, we
repurchased on the open market and subsequently retired an aggregate $26.2
million of our outstanding 2021 Notes.

Interest and Maturity. The Issuers issued the 2021 Notes pursuant to the 2021
Indenture in transactions exempt from registration requirements under the
Securities Act. The 2021 Notes were resold to qualified institutional buyers
pursuant to

                                       60
--------------------------------------------------------------------------------

Rule 144A under the Securities Act and to persons outside the United States pursuant to Regulation S under the Securities Act. The 2021 Notes will mature on February 15, 2021. The interest payment dates are February 15 and August 15.



Optional Redemption. The Issuers may on any one or more occasions redeem all or
a part of the 2021 Notes at a redemption price equal to 100% of the principal
amount thereof, plus accrued and unpaid interest, if any, to the applicable
redemption date on the 2021 Notes.

Certain Covenants. The 2021 Indenture restricts our ability and the ability of
certain of our subsidiaries to: (i) sell assets including equity interests in
our subsidiaries; (ii) pay distributions on, redeem or repurchase our units or
redeem or repurchase our subordinated debt; (iii) make investments; (iv) incur
or guarantee additional indebtedness or issue preferred units; (v) create or
incur certain liens; (vi) enter into agreements that restrict distributions or
other payments from our restricted subsidiaries to us; (vii) consolidate, merge
or transfer all or substantially all of our assets; (viii) engage in
transactions with affiliates; (ix) create unrestricted subsidiaries; (x) enter
into sale and leaseback transactions; or (xi) engage in certain business
activities. These covenants are subject to a number of important exceptions and
qualifications. If the 2021 Notes achieve an investment grade rating from each
of Moody's Investors Service, Inc. and Standard & Poor's Ratings Services and no
Default (as defined in the 2021 Indenture) has occurred and is continuing, many
of these covenants will terminate.

Events of Default. The 2021 Indenture provides that each of the following is an
Event of Default: (i) default for 30 days in the payment when due of interest on
the 2021 Notes; (ii) default in payment when due of the principal of, or
premium, if any, on the 2021 Notes; (iii) failure by us to comply with certain
covenants relating to asset sales, repurchases of the 2021 Notes upon a change
of control and mergers or consolidations; (iv) failure by us for 180 days after
notice to comply with our reporting obligations under the Exchange Act;
(v) failure by us for 60 days after notice to comply with any of the other
agreements in the 2021 Indenture; (vi) default under any mortgage, indenture or
instrument governing any indebtedness for money borrowed or guaranteed by us or
any of our restricted subsidiaries, whether such indebtedness or guarantee now
exists or is created after the date of the 2021 Indenture, if such default:
(a) is caused by a payment default; or (b) results in the acceleration of such
indebtedness prior to its stated maturity, and, in each case, the principal
amount of the indebtedness, together with the principal amount of any other such
indebtedness under which there has been a payment default or acceleration of
maturity, aggregates $20.0 million or more, subject to a cure provision;
(vii) failure by us or any of our restricted subsidiaries to pay final judgments
aggregating in excess of $20.0 million, which judgments are not paid, discharged
or stayed for a period of 60 days; (viii) except as permitted by the 2021
Indenture, any subsidiary guarantee is held in any judicial proceeding to be
unenforceable or invalid or ceases for any reason to be in full force or effect,
or any 2021 Guarantor, or any person acting on behalf of any Guarantor, denies
or disaffirms its obligations under its subsidiary guarantee; and (ix) certain
events of bankruptcy, insolvency or reorganization described in the 2021
Indenture with respect to the Issuers or any of our restricted subsidiaries that
is a significant subsidiary or any group of restricted subsidiaries that, taken
together, would constitute a significant subsidiary of us. Upon a continuing
Event of Default, the 2021 Trustee, by notice to the Issuers, or the holders of
at least 25% in principal amount of the then outstanding 2021 Notes, by notice
to the Issuers and the 2021 Trustee, may declare the 2021 Notes immediately due
and payable, except that an Event of Default resulting from entry into a
bankruptcy, insolvency or reorganization with respect to the Issuers, any
restricted subsidiary of us that is a significant subsidiary or any group of its
restricted subsidiaries that, taken together, would constitute a significant
subsidiary of us, will automatically cause the 2021 Notes to become due and
payable.

Revolving Credit Facility



At December 31, 2019, we maintained a $400.0 million revolving credit facility.
The revolving credit facility matures on (a) August 31, 2023, or (b) August 19,
2020 if the 2021 Notes have not been voluntarily refinanced on or prior to
August 19, 2020.

As of December 31, 2019, we had $201.0 million outstanding under the revolving
credit facility and $12.6 million of outstanding irrevocable letters of credit,
leaving a maximum available to be borrowed under our credit facility for future
revolving credit borrowings and letters of credit of $186.4 million. After
giving effect to our then current borrowings, outstanding letters of credit and
the financial covenants contained in our revolving credit facility, we had the
ability to borrow approximately $51.5 million in additional amounts thereunder
as of December 31, 2019.

The revolving credit facility is used for ongoing working capital needs and
general partnership purposes, and to finance permitted investments, acquisitions
and capital expenditures. During the year ended December 31, 2019, the
outstanding balance of our revolving credit facility has ranged from a low of
$201.0 million to a high of $455.0 million.

The credit facility is guaranteed by substantially all of our subsidiaries.
Obligations under the credit facility are secured by first priority liens on
substantially all of our assets and those of the guarantors, including, without
limitation,

                                       61
--------------------------------------------------------------------------------

inventory, accounts receivable, bank accounts, marine vessels, equipment, fixed
assets and the interests in our subsidiaries and certain of our equity method
investees.

We may prepay all amounts outstanding under the credit facility at any time
without premium or penalty (other than customary LIBOR breakage costs), subject
to certain notice requirements. The credit facility requires mandatory
prepayments of amounts outstanding thereunder with the net proceeds of certain
asset sales, equity issuances and debt incurrences.

Indebtedness under the credit facility bears interest at our option at the
Eurodollar Rate (the British Bankers Association LIBOR Rate) plus an applicable
margin or the Base Rate (the highest of the Federal Funds Rate plus 0.50%, the
30-day Eurodollar Rate plus 1.0%, or the administrative agent's prime rate) plus
an applicable margin. We pay a per annum fee on all letters of credit issued
under the credit facility, and we pay a commitment fee per annum on the unused
revolving credit availability under the credit facility. The letter of credit
fee, the commitment fee and the applicable margins for our interest rate vary
quarterly based on our leverage ratio (as defined in the credit facility, being
generally computed as the ratio of total funded debt to consolidated earnings
before interest, taxes, depreciation, amortization and certain other non-cash
charges) and are as follows as of December 31, 2019:
                                                                       Eurodollar

At December 31, 2019, the applicable margin for revolving loans that are LIBOR
loans ranges from 2.25% to 3.50% and the applicable margin for revolving loans
that are base prime rate loans ranges from 1.25% to 2.50%. The applicable margin
for LIBOR borrowings at December 31, 2019 is 3.50%.

The credit facility includes financial covenants that are tested on a quarterly
basis, based on the rolling four quarter period that ends on the last day of
each fiscal quarter.

In addition, the credit facility contains various covenants, which, among other
things, limit our and our subsidiaries' ability to: (i) grant or assume liens;
(ii) make investments (including investments in our joint ventures) and
acquisitions; (iii) enter into certain types of hedging agreements; (iv) incur
or assume indebtedness; (v) sell, transfer, assign or convey assets;
(vi) repurchase our equity, make distributions and certain other restricted
payments, but the credit facility permits us to make quarterly distributions to
unitholders so long as no default or event of default exists under the credit
facility; (vii) change the nature of our business; (viii) engage in transactions
with affiliates; (ix) enter into certain burdensome agreements; (x) make certain
amendments to our organizational documents and other material agreements,
including the Omnibus Agreement and our material agreements; (xi) make capital
expenditures; and (xii) permit our joint ventures to incur indebtedness or grant
certain liens.

The credit facility contains customary events of default, including, without
limitation: (i) failure to pay any principal, interest, fees, expenses or other
amounts when due; (ii) failure to meet the quarterly financial covenants;
(iii) failure to observe any other agreement, obligation, or covenant in the
credit facility or any related loan document, subject to cure periods for
certain failures; (iv) the failure of any representation or warranty to be
materially true and correct when made; (v) our, or any of our subsidiaries'
default under other indebtedness that exceeds a threshold amount;
(vi) bankruptcy or other insolvency events involving us or any of our
subsidiaries; (vii) judgments against us or any of our subsidiaries, in excess
of a threshold amount; (viii) certain ERISA events involving us or any of our
subsidiaries, in excess of a threshold amount; (ix) a change in control (as
defined in the credit facility); and (x) the invalidity of any of the loan
documents or the failure of any of the collateral documents to create a lien on
the collateral.

The credit facility also contains certain default provisions relating to Martin
Resource Management Corporation. If Martin Resource Management Corporation no
longer controls our general partner, the lenders under the credit facility may
declare all amounts outstanding thereunder immediately due and payable. In
addition, an event of default by Martin Resource Management Corporation under
its credit facility could independently result in an event of default under our
credit facility if it is deemed to have a material adverse effect on us.

If an event of default relating to bankruptcy or other insolvency events occurs
with respect to us or any of our subsidiaries, all indebtedness under our credit
facility will immediately become due and payable. If any other event of default
exists under our credit facility, the lenders may terminate their commitments to
lend us money, accelerate the maturity of the indebtedness outstanding under the
credit facility and exercise other rights and remedies. In addition, if any
event of default exists under our credit facility, the lenders may commence
foreclosure or other actions against the collateral.

Capital Resources and Liquidity



Historically, we have generally satisfied our working capital requirements and
funded our debt service obligations and capital expenditures with cash generated
from operations and borrowings under our revolving credit facility.

At December 31, 2019, we had cash and cash equivalents of $2.8 million and
available borrowing capacity of $51.5 million in additional amounts under our
revolving credit facility with $201.0 million of borrowings outstanding.  Our
revolving credit facility matures on August 31, 2023 unless our 2021 Notes have
not been refinanced on or before August 19, 2020. We are currently seeking to
refinance the 2021 Notes, although no assurance can be given that we will be
able to refinance the 2021 Notes.

Upon the successful refinancing of the 2021 Notes, we expect that our primary
sources of liquidity to meet operating expenses, service our indebtedness, pay
distributions to our unitholders and fund capital expenditures will be provided
by cash flows generated by our operations, borrowings under our revolving credit
facility and access to the debt and equity capital markets.  Our ability to
generate cash from operations will depend upon our future operating performance,
which is subject to certain risks. Please read "Item 1A. Risk Factors - Risks
related to Our Business" for a discussion of such risks.  In addition, due to
the covenants in our revolving credit facility, our financial and operating
performance impacts the amount we are permitted to borrow under that facility.

To address these challenges, over the last 18 months, we have taken a number of
strategic actions to strengthen our balance sheet and reduce leverage, such as
asset dispositions and acquisitions, reductions in the distributions payable to
our unitholders and efforts to focus our growth on business segments with a
stronger economic outlook. For example, in an effort to preserve liquidity, we
recently reduced the quarterly cash distribution per common unit to $0.0625
beginning with the distribution payable for the fourth quarter of 2019.  We
expect this distribution reduction, along with the reduction announced in 2019,
to result in approximately $68.2 million in cash we can retain annually for debt
reduction and investment in higher return opportunities.

If we are unable to refinance the 2021 Notes and are unable to repay the
outstanding borrowings under our revolving credit facility on August 19, 2020,
we would be in default under our revolving credit facility.  An event of default
under our revolving credit facility would allow the lenders to declare the
balance outstanding thereunder due and payable in full, which could trigger
cross-defaults under other agreements, which could also result in the
acceleration of those obligations by the counterparties to those agreements.

The Partnership is in compliance with all debt covenants as of December 31, 2019 and expects to be in compliance for the next twelve months.

Interest Rate Risk



We are subject to interest rate risk on our credit facility due to the variable
interest rate and may enter into interest rate swaps to reduce this variable
rate risk.

Seasonality

A substantial portion of our revenues is dependent on sales prices of products,
particularly NGLs and fertilizers, which fluctuate in part based on winter and
spring weather conditions. The demand for NGLs is strongest during the winter
heating season and the refinery blending season. The demand for fertilizers is
strongest during the early spring planting season. However, our Terminalling and
Storage and Transportation business segments and the molten sulfur business are
typically not impacted by seasonal fluctuations and a significant portion of our
net income is derived from our Terminalling and Storage, Sulfur Services and
Transportation business segments. Further, extraordinary weather events, such as
hurricanes, have in the past, and could in the future, impact our Terminalling
and Storage and Transportation business segments.

Impact of Inflation



Inflation did not have a material impact on our results of operations in 2019,
2018 or 2017. Although the impact of inflation has been insignificant in recent
years, it is still a factor in the U.S. economy and may increase the cost to
acquire or replace property, plant and equipment. It may also increase the costs
of labor and supplies. In the future, increasing energy prices could adversely
affect our results of operations. Diesel fuel, natural gas, chemicals and other
supplies are recorded in operating expenses. An increase in price of these
products would increase our operating expenses which could adversely affect net
income. We cannot provide assurance that we will be able to pass along increased
operating expenses to our customers.

Environmental Matters



Our operations are subject to environmental laws and regulations adopted by
various governmental authorities in the jurisdictions in which these operations
are conducted. We incurred no material environmental costs, liabilities or
expenditures to mitigate or eliminate environmental contamination during 2019,
2018 or 2017.
