Statements that are predictive in nature, that depend upon or refer to future events or conditions or that include the words “believe,” “expect,” “anticipate,” “intend,” “estimate” and other expressions that are predictions of or indicate future events and trends and that do not relate to historical matters identify forward-looking statements. Our forward-looking statements include statements about our business strategy, our industry, our future profitability, our expected capital expenditures and the impact of such expenditures on our performance, the costs of being a publicly traded corporation and our capital programs.

A forward-looking statement may include a statement of the assumptions or bases underlying the forward-looking statement. We believe that we have chosen these assumptions or bases in good faith and that they are reasonable. You are cautioned not to place undue reliance on any forward-looking statements. You should also understand that it is not possible to predict or identify all such factors and should not consider the following list to be a complete statement of all potential risks and uncertainties. Factors that could cause our actual results to differ materially from the results contemplated by such forward-looking statements include:

uncertainty regarding our future operating results;

significant changes in the transportation industries that service our business, such as increased regulation and embargoes; and

plans, objectives, expectations and intentions contained in this Quarterly Report that are not historical.

All forward-looking statements speak only as of the date of this Quarterly Report. You should not place undue reliance on our forward-looking statements. Although forward-looking statements reflect our good faith beliefs at the time they are made, forward-looking statements involve known and unknown risks, uncertainties and other factors, including the factors described under Item 1A, “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2018, this Quarterly Report and in our other filings with the Securities and Exchange Commission (the “SEC”), which may cause our actual results, performance or achievements to differ materially from anticipated future results, performance or achievements expressed or implied by such forward-looking statements.

Notes to the Condensed Consolidated Financial Statements

(Dollars in thousands)

1. Organization and Background of Business

Description of Business

We are an independent provider of supply chain management and logistics solutions designed to drive efficiencies and reduce costs for the oil and natural gas industry. We manufacture and provide patented mobile proppant and chemical management systems that unload, store and deliver proppant and chemicals at oil and natural gas well sites. The systems are designed to address the challenges associated with transferring large quantities of proppant and chemicals to the well site, including the cost and management of last mile logistics.

The systems are deployed in most of the active oil and natural gas basins in the United States, including the Permian Basin, Eagle Ford Shale, SCOOP/STACK formations, Haynesville Shale, Rockies, Marcellus and Utica Shales and Bakken formation.

We also operate an independent, unit-train capable, high speed transload facility in Oklahoma (the “Kingfisher Facility”) that provides rail-to-truck transloading and high-efficiency sand silo storage and transloading services. Commercial operations at the Kingfisher Facility commenced in January 2018 and we completed construction at the end of July 2018.

We also provide software solutions to remotely monitor proppant inventory from the source mine to well site through our Railtronix® and Solaris Lens™ inventory management systems. Our customers use data from our software solutions to manage distribution of proppant and chemicals throughout their supply chain.

Initial Public Offering

Solaris Oilfield Infrastructure, Inc. (“Solaris Inc.” or the “Company”) was incorporated as a Delaware corporation in February 2017 for the purpose of completing an initial public offering (“IPO” or the “Offering”) and related transactions. Our IPO was completed on May 17, 2017.

In connection with the closing of the IPO, Solaris Inc. became the managing member of Solaris Oilfield Infrastructure, LLC (“Solaris LLC”) and is responsible for all operational, management and administrative decisions relating to Solaris LLC's business. Solaris Inc. consolidates the financial results of Solaris LLC and its subsidiaries and reports non-controlling interest related to the portion of the units in Solaris LLC (the “Solaris LLC Units”) not owned by Solaris Inc., which will reduce net income (loss) attributable to the holders of Solaris Inc.’s Class A common stock.

2. Summary of Significant Accounting Policies

Basis of Presentation and Consolidation

The accompanying interim unaudited condensed consolidated financial statements of Solaris Inc. have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). These financial statements reflect all normal recurring adjustments that are necessary for fair presentation. Operating results for the three months ended March 31, 2019 and 2018 are not necessarily indicative of the results that may be expected for the full year or for any interim period.

The unaudited interim condensed consolidated financial statements should be read in conjunction with Solaris Inc.’s Annual Report on Form 10-K for the year ended December 31, 2018.

As described in Note 1. “Organization and Background of Business”, the Company is the sole managing member for Solaris LLC and consolidates entities in which it has a controlling financial interest. All material intercompany transactions and balances have been eliminated upon consolidation.

Table of Contents

Use of Estimates

The preparation of condensed consolidated financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Significant estimates used in the preparation of these condensed consolidated financial statements include, but are not limited to, stock-based compensation, depreciation associated with property, plant and equipment and related impairment considerations of those assets, determination of fair value of intangible assets acquired in business combinations, determination of the present value of lease payments and right-of-use assets and certain other assets and liabilities. Actual results could differ from management’s best estimates as additional information or actual results become available in the future, and those differences could be material.

Cash

For the purposes of the statements of cash flows, the Company considers all short-term, highly liquid, investments with an original maturity of three months or less to be cash equivalents. Cash is deposited in demand accounts in federally insured domestic institutions to minimize risk. Accounts of each institution are insured by Federal Deposit Insurance Corporation. Cash balances at times may exceed federally-insured limits. We have not incurred losses related to these deposits.

Accounts Receivable

Accounts receivable consists of trade receivables recorded at the invoice amount, plus accrued revenue that is earned but not yet billed, less an estimated allowance for doubtful accounts (if any). Accounts receivable are generally due within 60 days or less, or in accordance with terms agreed with customers. The Company considers accounts outstanding longer than the payment terms past due. The Company determines the allowance by considering a number of factors, including the length of time trade accounts receivable are past due, previous loss history, the customer’s current ability to pay its obligation, and the condition of the general economy and the industry as a whole. Accounts receivable are written off when they are deemed uncollectible, and payments subsequently received on such receivables are credited to the allowance for doubtful accounts. Allowance for doubtful accounts was zero as of March 31, 2019 and December 31, 2018.

Inventories

Inventories consist of materials used in the manufacturing of the Company’s systems, which include raw materials and purchased parts and is stated at the lower of cost or net realizable value. Detail reviews are performed related to net realizable value, giving consideration to quality, excessive levels, obsolescence and other factors. Adjustments that reduce stated amounts will be recognized as impairments in the condensed consolidated statements of operations. There were no impairments recorded for the three months ended March 31, 2019 and 2018.

Property, Plant and Equipment

Property, plant and equipment are stated at cost, or fair value for assets acquired in a business combination, less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful service lives of the assets as noted below:


		Useful Life
Systems and related equipment		Up to 15 years
Machinery and equipment		3-10 years
Furniture and fixtures		5 years
Computer hardware		3 years
Computer software		5-10 years
Vehicles		5 years
Transloading facility and equipment		15-30 years
Buildings and leasehold improvements		15 years

Table of Contents

Systems that are in the process of being manufactured are considered property, plant and equipment. However, the systems do not depreciate until they are fully completed. Systems in process are a culmination of material, labor and overhead.

Expenditures for maintenance and repairs are charged against income (loss) as incurred. Betterments that increase the value or materially extend the life of the related assets are capitalized. Upon sale or disposition of property and equipment, the cost and related accumulated depreciation and amortization are removed from the condensed consolidated financial statements and any resulting gain or loss is recognized in the condensed consolidated statements of operations.

Definite-lived Intangible Assets

Identified intangible assets with determinable lives consist primarily of customer relationships, a non-competition agreement and software acquired in the acquisition of Railtronix, LLC (“Railtronix”), as well as patents that were filed for our systems and other intellectual property. Amortization on these assets is calculated on the straight-line method over the estimated useful lives of the assets, which is five to fifteen years based on estimates the Company believes are reasonable. The Company recorded amortization expense of $195 and $216 for the three months ended March 31, 2019 and 2018, respectively.

Identified intangible assets by major classification consist of the following:


			Accumulated		Net Book
	Gross		Amortization		Value
As of March 31, 2019:
Customer relationships	$	4,703	$	(896)	$	3,807

The Company accounts for leases in accordance with Accounting Standards Codification (“ASC”) Topic 842, Leases (“ASC Topic 842”), which the Company adopted effective January 1, 2019. The Company applied ASC Topic 842 to all leases existing at or commencing after January 1, 2019 and elected the package of transition practical expedients for expired or existing contracts, which does not require reassessment of: (1) whether any of our contracts are or contain leases, (2) lease classification and (3) initial direct costs. The Company also elected the practical expedient to adopt the new lease requirements through a cumulative effect adjustment in the period of adoption and did not adjust comparative periods. As a result of the adoption of ASC Topic 842 on January 1, 2019, the Company recorded operating ROU assets of $8,503, operating lease liabilities of $9,016 and a cumulative effect adjustment to retained earnings for operating leases of $532.

We determine if an arrangement is a lease at inception. The Company made the election to not apply the recognition requirements in ASC Topic 842 to short-term leases (i.e., leases of twelve months or less). Instead, the Company recognizes the lease payments in profit or loss on a straight-line basis over the lease term. Operating leases are included in operating lease ROU assets, current portion of operating lease liabilities, and operating lease liabilities, net of current in the Company’s condensed consolidated balance sheets. Finance leases are included in property and equipment, current

Table of Contents

portion of finance lease liabilities, and finance lease liabilities, net of current in the Company’s condensed consolidated balance sheets.

ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. ROU assets and liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. As most of the Company’s leases do not provide an implicit rate, we use our incremental borrowing rate in determining the present value of lease payments based on the information available at the commencement date. Our incremental borrowing rate reflects the estimated rate of interest that we would pay to borrow on a collateralized basis over a similar term an amount equal to the lease payments in a similar economic environment. We use the implicit rate when readily determinable. The ROU asset also includes any lease payments made and excludes lease incentives received. The Company’s lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term.

Goodwill

Goodwill represents the excess of the purchase price of a business over the estimated fair value of the identifiable assets acquired and liabilities assumed. As of March 31, 2019 and December 31, 2018, the Company reported $17,236 of goodwill related to the 2014 purchase of the silo manufacturing business from Loadcraft Industries Ltd. and the 2017 purchase of the assets of Railtronix. The Company evaluates goodwill for impairment annually, as of October 31, or more often as facts and circumstances warrant. Factors such as unexpected adverse economic conditions, competition and market changes may require more frequent assessments. There was no impairment for the three months ended March 31, 2019 and 2018.

Before employing detailed impairment testing methodologies, the Company may first evaluate the likelihood of impairment by considering qualitative factors relevant to the business, such as macroeconomic, industry, market or any other factors that have a significant bearing on fair value. If the Company first utilizes a qualitative approach and determines that it is more likely than not that goodwill is impaired, detailed testing methodologies are then applied. Otherwise, the Company concludes that no impairment has occurred. The Company may also choose to bypass a qualitative approach and opt instead to employ detailed testing methodologies, regardless of a possible more likely than not outcome. If the Company determines through the qualitative approach that detailed testing methodologies are required, or if the qualitative approach is bypassed, the Company compares the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit.

Impairment of Long-Lived Assets and Definite-lived Intangible Assets

Long-lived assets, such as property, plant, equipment and definite-lived intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable, such as insufficient cash flows or plans to dispose of or sell long-lived assets before the end of their previously estimated useful lives. If the carrying amount is not recoverable, the Company recognizes an impairment loss equal to the amount by which the carrying amount exceeds fair value. The Company estimates fair value based on projected future discounted cash flows. Fair value calculations for long-lived assets and intangible assets contain uncertainties because it requires the Company to apply judgment and estimates concerning future cash flows, strategic plans, useful lives and market performance. The Company also applies judgment in the selection of a discount rate that reflects the risk inherent in the current business model. There was no impairment indicators for the three months ended March 31, 2019 and 2018.

Revenue Recognition

In determining the appropriate amount of revenue to be recognized as we fulfill our obligations under the agreement, the following steps must be performed at contract inception: (i) identification of the promised goods or services in the contract; (ii) determination of whether the promised goods or services are performance obligations, including whether they are distinct in the context of the contract; (iii) measurement of the transaction price, including the

Table of Contents

constraint on variable consideration; (iv) allocation of the transaction price to the performance obligations; and (v) recognition of revenue when (or as) we satisfy each performance obligation.

Revenues from system rental consist primarily of fixed monthly fees charged to customers for the use of our patented mobile proppant management systems that unload, store and deliver proppant and chemicals at oil and natural gas well sites, which is considered to be our performance obligation. Contracts with customers are typically on thirty- to sixty-day payment terms. Revenues are recognized over time as the performance obligations are satisfied under the terms of the customer contract. We determined that the performance obligation is satisfied over time as the customer simultaneously receives and consumes the benefits provided by the entity’s performance of services, typically as our systems are used by the customer. We measure progress using an input method based on resources consumed or expended relative to the total resources expected to be consumed or expended. We typically charge our customers for the rental of our systems on a monthly basis under agreements requiring the rental of a minimum number of systems for a period of twelve months. The Company is typically entitled to short fall payments if such minimum contractual obligations are not maintained by our customers. Minimum contractual obligations have been maintained and thus the Company has not recognized revenues related to shortfalls on such take or pay contractual obligations to date.

Revenues from system services consist primarily of the fees charged to customers for services including mobilization and transportation of our systems, field supervision and support and services coordinating proppant delivery to systems, each of which are considered to be separate performance obligations. Contracts with customers are typically on thirty- to sixty-day payment terms. Revenues are recognized over time as the performance obligations are satisfied under the terms of the customer contract. We determined that the performance obligation for system services including field supervision and support is satisfied over time as the customer simultaneously receives and consumes the benefits provided by the entity’s performance of the services, typically based on fixed weekly or monthly contractual rates for field supervision and support and when the Company provides services coordinating proppant delivery. We measure progress using an input method based on resources consumed or expended relative to the total resources expected to be consumed or expended. When the Company provides mobilization and transportation of our systems on behalf of our customers, we determined that the performance obligation is satisfied at a point in time when the system has reached its intended destination.

Revenues from transloading services consist primarily of the fees charged to customers for transloading proppant at our transloading facility, which is considered to be our performance obligation. Transloading services operations commenced in January 2018. We provide rail-to-truck transloading and high-efficiency sand silo storage and transloading services at the facility. Contracts with customers are typically on thirty- to sixty-day payment terms. Revenues are typically recognized over time as the customer simultaneously receives and consumes the benefits provided by the entity’s performance of the transloading service based on a throughput fee per ton rate for proppant delivered to and transloaded at the facility. We measure progress based on the proppant delivered and transloaded at the facility. Under our agreements at the facility, quarterly minimum throughput volumes are required and the Company is entitled to short fall payments if such minimum quarterly contractual obligations are not maintained. These shortfalls are based on fixed minimum volumes at a fixed rate and are recognized over time as throughput volumes transloaded are below minimum throughput volumes required. The Company recorded $474 of shortfall revenue during the three months ended March 31, 2019.

Revenues from inventory software services consist primarily of the fees charged to customers for the use of our Railtronix inventory management software, which is considered to be our performance obligation. Revenues are recognized over time as the customer simultaneously receives and consumes the benefits provided by the entity’s performance based on a throughput fee to monitor proppant that is loaded into a railcar, stored at a transload facility or loaded into a truck.

Deferred Revenue

Table of Contents

which will be recognized as Revenue from transloading services over the remaining two-year term of the modified agreement. The Company recognized $3,134 of deferred revenue as Revenue from transloading services in the condensed consolidated statements of operations for the three months ended March 31, 2019. No deferred revenue was recorded or recognized as revenue during the three months ended March 31, 2018.

Unbilled Receivables

Revenues recognized in advance of invoice issuance create assets referred to as “unbilled receivables.” These assets are presented on a combined basis with accounts receivable and are converted to accounts receivable once billed.

Stock-based Compensation

The Company accounts for its stock-based compensation including grants of restricted stock and options in the condensed consolidated statements of operations based on their fair values on the date of grant. The Company recognizes expense on a straight-line basis over the awards’ vesting period, which is generally the requisite service period.

Research and Development

The Company expenses research and development costs as incurred, which is included in selling, general and administrative expenses in the condensed consolidated statements of operations. There were no research and development costs for the three months ended March 31, 2019 and 2018.

Financial Instruments

The carrying value of the Company’s financial instruments, consisting of cash, accounts receivable, notes receivable, accounts payable, insurance premium financing and accrued expenses, approximates their fair value due to the short maturity of such instruments. Financial instruments also consist of a revolving credit facility and term loans, for which fair value approximates carrying value as the debt bears interest at a variable rate which is reflective of current rates otherwise available to the Company. As of March 31, 2019, we had no borrowings under the 2018 Credit Agreement (as defined below) outstanding. Unless otherwise noted, it is management’s opinion that the Company is not exposed to significant interest, currency or credit risks arising from these financial instruments.

Fair Value Measurements

The Company’s financial assets and liabilities are to be measured using inputs from the three levels of the fair value hierarchy, of which the first two are considered observable and the last unobservable, which are as follows:

Level 1—Inputs are unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date;

Level 2—Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active or other inputs corroborated by observable market data for substantially the full term of the assets or liabilities; and

Level 3—Unobservable inputs that reflect the Company’s assumptions that market participants would use in pricing assets or liabilities based on the best information available.

Income Taxes

Solaris Inc. is a corporation and, as a result, is subject to United States federal, state and local income taxes. For the three months ended March 31, 2019 and 2018, we recognized a combined United States federal and state provision for income taxes of $4,181 and $2,027, respectively.

Table of Contents

Solaris LLC is treated as a partnership for United States federal income tax purposes and therefore does not pay United States federal income tax on its taxable income. Instead, the Solaris LLC members are liable for United States federal income tax on their respective shares of the Company’s taxable income reported on the members’ United States federal income tax returns.

Our revenues are derived through transactions in several states, which may be subject to state and local taxes. Accordingly, we have recorded a liability for state and local taxes that management believes is adequate for activities as of March 31, 2019 and December 31, 2018.

We account for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events included in the condensed consolidated financial statements. Under this method, we determine deferred tax assets and liabilities on the basis of the differences between the book value and tax bases of assets and liabilities by using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period in which the enactment date occurs.

We recognize deferred tax assets to the extent we believe these assets are more-likely-than-not to be realized. In making such a determination, we consider all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax planning strategies and recent results of operations.

Interest and penalties related to income taxes are included in the benefit (provision) for income taxes in our condensed consolidated statement of operations. We have not incurred any significant interest or penalties related to income taxes in any of the periods presented.

See Note 9. “Income Taxes” for additional information regarding income taxes.

Payable Related to the Tax Receivable Agreement

In connection with the IPO, Solaris Inc. entered into a Tax Receivable Agreement (the “Tax Receivable Agreement”) with the members of Solaris LLC immediately prior to the IPO (each such person and any permitted transferee, a “TRA Holder,” and together, the “TRA Holders”) on May 17, 2017. This agreement generally provides for the payment by Solaris Inc. to each TRA Holder of 85% of the net cash savings, if any, in United States federal, state and local income tax and franchise tax that Solaris Inc. actually realizes (computed using simplifying assumptions to address the impact of state and local taxes) or is deemed to realize in certain circumstances in periods after the IPO as a result of (i) certain increases in tax basis that occur as a result of Solaris Inc.’s acquisition (or deemed acquisition for United States federal income tax purposes) of all or a portion of such TRA Holder’s Solaris LLC Units in connection with the IPO or pursuant to the exercise of the Redemption Right or the Call Right (each as defined in Solaris LLC’s Second Amended and Restated Limited Liability Company Agreement (the “Solaris LLC Agreement”)) and (ii) imputed interest deemed to be paid by Solaris Inc. as a result of, and additional tax basis arising from, any payments Solaris makes under the Tax Receivable Agreement. Solaris Inc. will retain the benefit of the remaining 15% of these cash savings. As of March 31, 2019 and December 31, 2018, Solaris Inc. recorded a payable related to the Tax Receivable Agreement of $66,648 and $56,149, respectively. The increase in payables related to the Tax Receivable Agreement is a result of Solaris Inc.’s acquisition (or deemed acquisition for United States federal income tax purposes) of Solaris LLC Units from TRA Holders.

Environmental Matters

The Company is subject to various federal, state and local laws and regulations relating to the protection of the environment. Management has established procedures for the ongoing evaluation of the Company’s operations, to

Table of Contents

identify potential environmental exposures and to comply with regulatory policies and procedures. Environmental expenditures that relate to current operations are expensed or capitalized as appropriate. Expenditures that relate to an existing condition caused by past operations and do not contribute to current or future revenue generation are expensed as incurred. Liabilities are recorded when environmental costs are probable, and the costs can be reasonably estimated. The Company maintains insurance which may cover in whole or in part certain environmental expenditures. As of March 31, 2019 and December 31, 2018, there were no environmental matters deemed probable.

Segment Information

Operating segments are identified as components of an enterprise about which separate discrete financial information is available for evaluation by the chief operating decision maker, or decision-making group, in making decisions on how to allocate resources and assess performance. The Company’s chief operating decision maker is the Chief Executive Officer. The Company and the Chief Executive Officer view the Company’s operations and manage its business as one operating segment. All long-lived assets of the Company reside in the United States.

Accounting Standards Recently Issued But Not Yet Adopted

In August 2018, the Financial Accounting Standards Board (the “FASB”) issued ASU No. 2018-13, Fair Value Measurement (Topic 820), Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018-13”), which modifies the disclosure requirements in Topic 820, Fair Value Measurement, by removing certain disclosure requirements related to the fair value hierarchy, modifying existing disclosure requirements related to measurement uncertainty and adding new disclosure requirements, such as disclosing the changes in unrealized gains and losses for the period included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period and disclosing the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. The amendments in ASU 2018-13 are effective for all entities for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. We are currently in the process of evaluating the impact, if any, that ASU 2018-13 will have on our condensed consolidated financial statements.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which replaces the incurred loss impairment methodology under current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. ASU 2016-13 requires the use of a forward-looking expected credit loss model for accounts receivables, loans and other financial instruments. For public business entities, the amendments are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, with early adoption permitted. Adoption of ASU 2016-13 will be applied using a modified-retrospective approach through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. We are currently in the process of evaluating the impact, if any, that ASU 2016-13 will have on our condensed consolidated financial statements.

7. Senior Secured Credit Facility

On January 19, 2018, we entered into a credit agreement (the “2018 Credit Agreement”) by and among the Company, as borrower, each of the lenders party thereto and Woodforest National Bank, as administrative agent (the “2018 Credit Agreement Administrative Agent”). The 2018 Credit Agreement replaced, in its entirety, the Company’s prior credit facility, as amended on May 17, 2017, by and among the Company, as borrower, each of the lenders party thereto and the 2018 Credit Agreement Administrative Agent. The 2018 Credit Agreement consisted of a $50,000 advancing term loan (the “Advance Loan”) and a $20,000 revolving loan, with a $10,000 uncommitted accordion option to increase the total revolving loans (the “Revolving Loan”, and together with the Advance Loan, the “Loans”). No lender had any obligation to increase its own revolving credit commitment. The Advance Loan amortized beginning in April 2019 and each of the Loans matured on January 19, 2022. Our obligations under the Loans were generally secured by a pledge of substantially all of the assets of the Company and its subsidiaries, and such obligations were guaranteed by our domestic subsidiaries other than Immaterial Subsidiaries (as defined in the 2018 Credit Agreement). We had the option to prepay the loans at any time without penalty.

The 2018 Credit Agreement permitted extensions of credit under the Advance Loan through the end of April 2019 and under the Revolving Loan until January 19, 2022. Borrowings under the Revolving Loan were limited by both commitments and a borrowing base determined monthly by calculating percentages of the eligible accounts and the eligible inventory, provided that the portion of the borrowing base attributable to eligible inventory could not exceed 35% of the entire borrowing base. Borrowings under the Advance Loan were not to exceed 80% of the then current net orderly liquidation value of the applicable equipment or facility build out or the applicable equipment constructed or acquired which was then subject to the liens securing the Loans.

As of December 31, 2018 we had $13,000 of borrowings outstanding under the 2018 Credit Agreement. During the three months ended March 31, 2019, all outstanding borrowings were repaid and as of March 31, 2019, we had no borrowings under the 2018 Credit Agreement outstanding.

Borrowings under the 2018 Credit Agreement bore interest at one-month LIBOR plus an applicable margin and interest were payable monthly. The applicable margin ranged from 3.00% to 3.50% depending on our senior leverage ratio. Borrowings under the Revolving Loan had a weighted average interest rate of 5.49%, for the three months ended March 31, 2019. The 2018 Credit Agreement required that we pay a monthly commitment fee on undrawn amounts of the Revolving Loan, ranging from 0.25% to 0.50% depending upon the average outstanding balance of the obligations relative to the Revolving Loan commitments.

Table of Contents

subtracted from indebtedness and senior indebtedness, respectively, an amount equal to the lesser of $10,000 or 50% of unrestricted cash and cash equivalents of the Company and its subsidiaries. EBITDA, as defined in the 2018 Credit Agreement, excluded certain noncash items and any extraordinary, unusual or non-recurring gains, losses or expenses.

The 2018 Credit Agreement also required that we maintain a ratio of consolidated EBITDA to fixed charges of not less than 1.25 to 1.00. Capital expenditures were permitted up to $75,000 for fiscal year ending December 31, 2019 and each fiscal year thereafter. In addition, for fiscal years beginning on January 1, 2020, any unused availability for capital expenditures from the immediately preceding fiscal year may be carried forward to the subsequent year; provided, however that we were permitted to make any capital expenditures in an amount equal to the proceeds of equity contributions made to the Company used to fund such capital expenditures.

As of March 31, 2019, we were in compliance will all covenants in accordance with the 2018 Credit Agreement.

On April 26, 2019, we entered into an Amended and Restated Credit Agreement (the “2019 Credit Agreement”) by and among the Company, as borrower, each of the lenders party thereto and Wells Fargo Bank, National Association, as administrative agent. The 2019 Credit Agreement replaced, in its entirety, the Company’s 2018 Credit Agreement. The 2019 Credit Agreement increases the revolving loan to $50.0 million, with availability based on a total leverage covenant of 2.5x total debt to EBITDA. The 2019 Credit Agreement includes a $25.0 million uncommitted accordion option to increase the total revolving loan to $75.0 million. As of April 30, 2019, the Company has $50.0 million of availability under its undrawn credit facility.

8. Equity

Dividends

On March 29, 2019, the Company paid a quarterly cash dividend of $0.10 per share of Class A common stock. Solaris LLC paid a distribution of $4,757, or $0.10 per Solaris LLC Unit, to all Solaris LLC unitholders as of March 22, 2019, $3,119 of which was paid to the Company. The Company used the proceeds from the distribution to pay the dividend to all holders of shares of Class A common stock as of March 22, 2019, which totaled $3,119, including $79 related to shares of restricted stock.

Stock-based compensation

Effective May 17, 2017, both the Board of Directors of Solaris Inc. (the “Board”) and the holder of all Solaris Inc.’s then-outstanding equity interests adopted the LTIP for the benefit of employees, directors and consultants of the Company and its affiliates. The LTIP provides for the grant of all or any of the following types of equity-based awards: (1) incentive stock options qualified as such under United States federal income tax laws; (2) stock options that do not qualify as incentive stock options; (3) stock appreciation rights; (4) restricted stock awards; (5) restricted stock units; (6) bonus stock; (7) performance awards; (8) dividend equivalents; (9) other stock-based awards; (10) cash awards; and (11) substitute awards.

Subject to adjustment in accordance with the terms of the LTIP, 5,118,080 shares of Solaris Inc.’s Class A common stock have been reserved for issuance pursuant to awards under the LTIP. Class A common stock withheld to satisfy exercise prices or tax withholding obligations will be available for delivery pursuant to other awards. The LTIP will be administered by the Board, the Compensation Committee of the Board or an alternative committee appointed by the Board.

In connection with the IPO, the options granted under the Plan were converted into options under the LTIP. A total of 591,261 options to purchase Class A common stock of the Company were issued to employees, directors and consultants at an exercise price of $2.87 per option, had a weighted average grant date fair value of $12.04 per option and had the same fair value as immediately prior to the conversion. The vesting terms from the options under the LTIP were accelerated from the previous vesting terms under the Plan such that, twenty-five percent (25%) of the options were considered vested upon the conversion, an additional 25% of the options vested on July 24, 2017 and the remaining options vested on November 13, 2017. As of March 31, 2019, 511,656 options have been exercised, 33,346 forfeited and 46,259 remain outstanding.

Table of Contents

The fair value of each option award is estimated on the date of grant using the Black-Scholes option-pricing model. Expected volatility is based on implied volatilities from historical trading of publicly traded companies which are in the same industry sector. The simplified method is used to derive an expected term. The expected term represents an estimate of the time options are expected to remain outstanding. The risk-free rate for periods within the contractual life of the option is based on the United States treasury yield curve in effect at the time of grant. Compensation cost, as measured at the grant date fair value of the award, is recognized as an expense over the employee’s requisite service period for service-based awards (generally the vesting period of the award of four years). For the three months ended March 31, 2019 and 2018, the Company did not recognize stock-based compensation expense on options.

The Company accounts for its stock-based compensation including grants of restricted stock in the condensed consolidated statements of operations based on their estimated fair values on the date of grant. The following table further summarizes activity related to restricted stock for the three months ended March 31, 2019 and 2018:


	Restricted Stock Awards
	2019	2018
Unvested at January 1,	411,497	1,218,265
Awarded	375,068	2,120
Vested	(706)	—
Forfeited	(405)	(848)
Unvested at March 31,	785,454	1,219,537

For the three months ended March 31, 2019, the Company recognized $4, $64, $3 and $791 of stock-based compensation expense on restricted stock in cost of system rental, cost of system services, cost of transloading services and salaries, benefits and payroll taxes, respectively, in the condensed consolidated statements of operations and $37 within property, plant and equipment, net in the condensed consolidated balance sheets. For the three months ended March 31, 2018, the Company recognized $5, $40 and $1,468 of stock-based compensation expense on restricted stock in cost of system rental, cost of system services and salaries, benefits and payroll taxes, respectively, in the condensed consolidated statements of operations and $361 within property, plant and equipment, net in the condensed consolidated balance sheets. Compensation expense includes adjustment for forfeitures as incurred. As of March 31, 2019, 785,454 shares of restricted stock are issued and are outstanding. 213,501 shares, 304,680 shares, 142,252 shares and 125,021 shares of restricted stock vest in 2019, 2020, 2021 and 2022, respectively.

Earnings Per Share

Basic earnings per share of Class A common stock is computed by dividing net income attributable to Solaris by the weighted-average number of shares of Class A common stock outstanding during the same period. Diluted earnings per share is computed giving effect to all potentially dilutive shares.

Table of Contents

The following table sets forth the calculation of earnings per share, or EPS, for the three months ended March 31, 2019 and 2018:


	Three Months Ended March 31,
Basic net income per share:	2019		2018
Numerator
Net income attributable to Solaris	$	12,317	$	5,930
Less income attributable to participating securities (1)		(253)		(288)
Net income attributable to common stockholders	$	12,064	$	5,642

Earnings per share of Class A common stock - basic	$	0.43	$	0.24
Earnings per share of Class A common stock - diluted	$	0.43	$	0.23

(1) The Company’s restricted shares of common stock are participating securities.

(2) The three months ended March 31, 2019 and 2018 include 87 shares and 189 shares, respectively, of Class A common stock resulting from an assumed exercise of the stock options in the calculation of the denominator for diluted earnings per common share as these shares were dilutive.

The following number of weighted-average potentially dilutive shares were excluded from the calculation of diluted earnings per share because the effect of including such potentially dilutive shares would have been antidilutive upon conversion:

9. Income Taxes

Income Taxes

The Company is a corporation and, as a result is subject to United States federal, state and local income taxes. Solaris LLC is treated as a pass-through entity for United States federal tax purposes and in most state and local jurisdictions. As such, Solaris LLC’s members, including the Company, are liable for federal and state income taxes on their respective shares of Solaris LLC’s taxable income. Solaris LLC is liable for income taxes in those states not recognizing its pass-through status.

The effective combined United States federal and state income tax rates were 15.21% and 12.97% for the three months ended March 31, 2019 and 2018, respectively. For the three months ended March 31, 2019 and 2018, our effective tax rate differed from the statutory rate primarily due to Solaris LLC’s pass-through treatment for United States federal income tax purposes.

Based on our cumulative earnings history and forecasted future sources of taxable income, we believe that we will be able to realize our deferred tax assets in the future. As the Company reassesses these assumptions in the future, changes in forecasted taxable income may alter this expectation and may result in an increase in to the valuation allowance and an increase in the effective tax rate.

Table of Contents

The Company evaluates its tax positions and recognizes only tax benefits that, more likely than not, will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. The tax position is measured at the largest amount of benefit that has a greater than 50.0% likelihood of being realized upon settlement. As of March 31, 2019 and December 31, 2018, the Company’s uncertain tax benefits totaling $816 are reported as a component of the net deferred tax asset in the condensed consolidated balance sheets. The full balance of unrecognized tax benefits as of March 31, 2019, if recognized, would affect the effective tax rate. However, we do not believe that any of the unrecognized tax benefits will be realized within the coming year. The Company has elected to recognize interest and penalties related to unrecognized tax benefits in income tax expense notwithstanding the fact that, as of March 31, 2019, the Company has not accrued any penalties or interest.

Payables Related to the Tax Receivable Agreement

As of March 31, 2019, our liability under the Tax Receivable Agreement was $66,648, representing 85% of the calculated net cash savings in United States federal, state and local income tax and franchise tax that Solaris Inc. anticipates realizing in future years from certain increases in tax basis and certain tax benefits attributable to imputed interest as a result of Solaris Inc.’s acquisition (or deemed acquisition for United States federal income tax purposes) of Solaris LLC Units in connection with the IPO or pursuant to an exercise of the Redemption Right or the Call Right (each as defined in the Solaris LLC Agreement).

The projection of future taxable income involves significant judgment. Actual taxable income may differ from our estimates, which could significantly impact our liability under the Tax Receivable Agreement. We have determined it is more-likely-than-not that we will be able to utilize all of our deferred tax assets subject to the Tax Receivable Agreement; therefore, we have recorded a liability under the Tax Receivable Agreement related to the tax savings we may realize from certain increases in tax basis and certain tax benefits attributable to imputed interest as a result of Solaris Inc.’s acquisition (or deemed acquisition for United States federal income tax purposes) of Solaris LLC Units in connection with the IPO or pursuant to an exercise of the Redemption Right or the Call Right (each as defined in the Solaris LLC Agreement). If we determine the utilization of these deferred tax assets is not more-likely-than-not in the future, our estimate of amounts to be paid under the Tax Receivable Agreement would be reduced. In this scenario, the reduction of the liability under the Tax Receivable Agreement would result in a benefit to our condensed consolidated statement of operations.

10. Concentrations

For the three months ended March 31, 2019, four customers accounted for 15%, 13%, 12% and 11% of the Company’s revenue.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Unless the context requires otherwise, references in this Quarterly Report to “Solaris,” the "Company," "we," "us," and "our" refer to (i) Solaris Oilfield Infrastructure, LLC (“Solaris LLC”) and its consolidated subsidiaries prior to the completion of our initial public offering and (ii) Solaris Oilfield Infrastructure, Inc. ("Solaris Inc.") and its consolidated subsidiaries following the completion of our initial public offering. The following discussion and analysis of our financial condition and results of operations should be read in conjunction with the accompanying financial statements and related notes. The following discussion contains “forward-looking statements” that reflect our plans, estimates, beliefs and expected performance. Our actual results may differ materially from those anticipated as discussed in these forward-looking statements as a result of a variety of risks and uncertainties, including those described above in “Cautionary Statement Regarding Forward-Looking Statements” included elsewhere in this Quarterly Report and “Risk Factors” included in the Annual Report on Form 10-K for the year ended December 31, 2018 as updated by our subsequent filings with the Securities and Exchange Commission (the “SEC”), all of which are difficult to predict. In light of these risks, uncertainties and assumptions, the forward-looking events discussed may not occur. We assume no obligation to update any of these forward-looking statements except as otherwise required by law.

Overview

Solaris LLC was formed in July 2014. Solaris Inc. was incorporated as a Delaware corporation in February 2017 for the purpose of completing an initial public offering of equity in May 2017 (the “IPO” or the “Offering”) and related transactions. On May 11, 2017, in connection with the IPO, Solaris Inc. became a holding company whose sole material asset consists of units in Solaris LLC (“Solaris LLC Units”). Solaris Inc. became the managing member of Solaris LLC and is responsible for all operational, management and administrative decisions relating to Solaris LLC’s business and consolidates the financial results of Solaris LLC and its subsidiaries.

Executive Summary

We design, manufacture, rent and service specialized equipment that helps oil and natural gas operators and their suppliers drive efficiencies and reduce costs during the completion phase of well development. The majority of our revenue is currently derived from the rental and service of our patented mobile proppant and chemical management systems that unload, store and deliver proppant and chemicals at oil and natural gas well sites. Our systems are deployed in most of the active oil and natural gas basins in the United States, including the Permian Basin, Eagle Ford Shale, SCOOP/STACK formations, Haynesville Shale, Rockies, Marcellus and Utica Shales and Bakken formation.

In 2018 and early 2019, we introduced a new product line and product enhancements, which we believe will help us maintain and expand our total revenue opportunity in the United States completions equipment and service space. We introduced our mobile chemical management system to the market in late 2018 and we have begun commercializing the offering in 2019. Product enhancements introduced in 2018 include our AutoHopper technology, which we are deploying across our fleet to automate the delivery of proppant into the blender, and the latest version of our Solaris Lens™ software, which is available on our systems and allows customers to view the entire last mile proppant supply chain in real time.

Recent Trends and Outlook

Demand for our products and services is predominantly influenced by the level of oil and natural gas well drilling and completion activity, which, in turn, depends largely on the current and anticipated profitability of developing oil and natural gas reserves. More specifically, demand for our products and services is driven by demand for proppant and chemicals, which, in turn, is primarily driven by advancements in oil and natural gas drilling and well completion technology and techniques, such as horizontal drilling and hydraulic fracturing. These adjustments have made the extraction of oil and natural gas increasingly cost-effective in formations that historically would have been uneconomic to develop, thereby increasing the number of wells and stages that are completed.

According to the Baker Hughes’ Rig Count, the average number of active land-based drilling rigs in the United States was up 18% year over year in 2018 to 1,013 average active rigs, following a 76% year-over-year increase in average active land rigs in 2017. In the first quarter of 2019, the Baker Hughes’ Rig Count dropped 7% sequentially.

Table of Contents

While the drilling rig count is generally a fair indicator of the overall oil and natural gas activity level in the United States, continued advancements in drilling rig and hydraulic fracturing efficiency have contributed to an increase in the number of wells and stages completed. According to Coras Research, LLC, the number of wells completed in 2018 increased over 20% from 2017 and the number of stages completed increased over 30% year-over-year. This combination of increased drilling activity and efficiency contributed to an increase of over 35% in total United States proppant demand from 2017 to 2018. Most recently, Coras Research, LLC estimated the number of wells completed in the first quarter of 2019 increased 4% from the first quarter of 2018 and the number of stages completed increased over 11% year-over-year.

While drilling and completion activity has been relatively flat in 2019 versus 2018, a continued stable oil price environment could allow the total number of well completions to increase year-over-year. Such increases may also be driven by continued pressure pumping efficiency gains, a drawdown of drilled, but uncompleted well inventories and a continued transition towards manufacturing-style development activity by exploration and production (“E&P”) companies. Examples of E&P development activity trends include “zipper fracs” (the process of completing multiple adjacent wells simultaneously), “leap frogging” (forward staging equipment and supplies to prepare for completion activity) and continuous completion rates, which drives cost efficiencies and increases demand for completion-related consumables such as proppant and chemicals.

These industry trends have contributed to our significant growth in recent years. Our fleet currently consists of 162 mobile proppant management systems, which is up 65% from 98 systems a year ago, and five mobile chemical management systems, which did not exist as a product offering a year ago. We expect to end the second quarter of 2019 with 164 mobile proppant management systems and 14 mobile chemical management systems.

We also significantly increased the number of our systems deployed to customers. In the three months ended March 31, 2019, we averaged 114 mobile proppant systems on a fully utilized basis, which was up 34% compared to the three months ended March 31, 2018. The majority of our chemical systems are in field trials with customers as we work towards broader market acceptance of this new product.

We previously used revenue days, the combined number of days that its systems earned revenue during the quarter, as the primary measure of business activity. Going forward, we believe the fully utilized system count will be a more comparative metric to measure period-over-period changes in our rental activity as it will normalize for varying calendar days period-over-period.

How We Generate Revenue

We generate the majority of our revenue through the rental of our systems and related services, including transportation of our systems, transportation of proppant to the well site and field supervision and support. The system rental and provision of related services are performed under a variety of contract structures, primarily master service agreements as supplemented by individual work orders detailing statements of work, pricing agreements and specific quotes. The master service agreements generally establish terms and conditions for the provision of our systems and service on a well site, indemnification, damages, confidentiality, intellectual property protection and payment terms and provisions. The rentals and services are generally priced based on prevailing market conditions at the time the services are provided, giving consideration to the specific requirements and activity levels of the customer. We typically charge our customers for the rental of our systems on a monthly basis.

In early 2018, we began generating revenue for our transloading services at our independent, transload facility in Oklahoma (the “Kingfisher Facility”). We generally charge our customers a throughput fee for rail-to-truck transloading and high-efficiency sand silo storage and transloading services at the Kingfisher Facility. We expect that a significant portion of the transloading revenue that we generate in 2019 will be related to the customer contract that was amended in December 2018, requiring the customer to deliver minimum quarterly volumes to the Kingfisher Facility, as well as volumes from additional customers.

Finally, we generate revenue through our Railtronix® inventory management software. We generally charge our customers a throughput fee to monitor proppant that is loaded into a railcar, stored at a transload facility or loaded into a truck at either a transload facility or mine.

Costs of Conducting Our Business

The principal costs associated with operating our business are:

Cost of system rental (excluding depreciation and amortization);

Cost of system services (excluding depreciation and amortization);

Cost of transloading services (excluding depreciation and amortization);

Cost of software inventory management services (excluding depreciation and amortization);

Depreciation and amortization associated primarily with the costs to build our systems and the costs to develop rail and storage assets;

Salaries, benefits and payroll taxes;

Other operating expenses.

Our cost of system rental (excluding depreciation and amortization) consists primarily of the costs of maintaining our equipment, developing and maintaining our Solaris Lens software, as well as insurance and property taxes related to our equipment.

Our cost of system services (excluding depreciation and amortization) consists primarily of direct labor costs, and related travel and lodging expenses, system transportation costs and proppant transportation costs. A large portion of our cost of system services (excluding depreciation and amortization) are variable based on the number of systems deployed with customers.

Our cost of transloading operations and services (excluding depreciation and amortization) consists primarily of direct labor costs, fuel, utilities, and maintenance.

Table of Contents

Our cost of software inventory management services (excluding depreciation and amortization) consists primarily of direct labor and software subscriptions.

Our depreciation and amortization expense primarily consists of the depreciation expense related to our systems and related manufacturing machinery and equipment as well as rail and transloading equipment. The costs to build our systems, including any upgrades, are capitalized and depreciated over a life ranging from three to 15 years. The costs to build our rail and transloading storage assets are capitalized and depreciated over a life of 15 to 30 years.

Our salaries, benefits and payroll taxes are comprised of the salaries and related benefits for several functional areas of our organization, including sales and commercial, research and development, manufacturing administrative, accounting and corporate administrative.

Our selling, general and administrative expenses are comprised primarily of office rent, marketing expenses and third-party professional service providers.

How We Evaluate Our Operations

We use a variety of qualitative, operational and financial metrics to assess our performance. Among other measures, management considers revenue, revenue days, fully utilized system count, tons transloaded, EBITDA and Adjusted EBITDA.

Revenue

We analyze our revenue by comparing actual monthly revenue to our internal projections for a given period and to prior periods to assess our performance. We also assess our revenue in relation to the number of systems we have deployed to customers and the amount of proppant and chemicals transloaded at our Kingfisher Facility from period to period.

Revenue Days

We view revenue days as an important indicator of our performance. We calculate revenue days as the combined number of days our sand and chemical systems earn revenue in a period. We assess our revenue days from period to period in relation to the number of sand and chemical systems we have available in our fleet.

Fully Utilized System Count

The fully utilized system count is calculated as the total number of revenue days divided the number of days in the period. We view the fully utilized system count as the best measure to track utilization and changes in rental activity on a period-over-period basis as the majority of our systems are rented on a monthly basis.

Tons Transloaded

We view tons transloaded as an important indicator of our performance. We calculate the number of tons transloaded as the combined number of proppant tons and chemicals that are transloaded at our Kingfisher Facility in a period. We assess the number of tons transloaded from period to period in relation to prior periods and contracted minimum volumes.

EBITDA and Adjusted EBITDA

We view EBITDA and Adjusted EBITDA as important indicators of performance. We define EBITDA as net income, plus (i) depreciation and amortization expense, (ii) interest expense and (iii) income tax expense, including franchise taxes. We define Adjusted EBITDA as EBITDA plus (i) stock-based compensation expense and (ii) certain non-cash items and any extraordinary, unusual or non-recurring gains, losses or expenses.

Table of Contents

Note Regarding Non-GAAP Financial Measures

EBITDA and Adjusted EBITDA are not financial measures presented in accordance with accounting principles generally accepted in the United States (“GAAP”). We believe that the presentation of these non-GAAP financial measures will provide useful information to investors in assessing our financial condition and results of operations. Net income (loss) is the GAAP measure most directly comparable to EBITDA and Adjusted EBITDA. Our non-GAAP financial measures should not be considered as alternatives to the most directly comparable GAAP financial measure. Each of these non-GAAP financial measures has important limitations as analytical tools because they exclude some but not all items that affect the most directly comparable GAAP financial measures. You should not consider EBITDA or Adjusted EBITDA in isolation or as substitutes for an analysis of our results as reported under GAAP. Because EBITDA 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.

Our system rental revenue increased $9.9 million, or 36%, to $37.3 million for the three months ended March 31, 2019 compared to $27.4 million for the three months ended March 31, 2018. This increase was primarily due to a 34% increase in mobile proppant systems on a fully utilized basis, due to increasing demand for our sand and chemical systems and enhancements to our product offering.

System Services Revenue. Our system services revenue increased $3.9 million, or 52%, to $11.4 million for the three months ended March 31, 2019 compared to $7.5 million for the three months ended March 31, 2018. System services revenue related to field technicians and transportation increased as a result of the increasing number of systems we have deployed. Once systems are deployed, the Company provides services to maintain such systems on-site for

Table of Contents

customers and to coordinate the transportation of systems between customer sites. System services revenue also increased in relation to services provided to coordinate proppant and chemicals delivered into our systems.

Transloading Services Revenue. Our transloading services revenue increased $5.4 million, or 1,080%, to $5.8 million for the three months ended March 31, 2019 compared to $0.5 million for the three months ended March 31, 2018. This increase was primarily due to recognition of $3.1 million of deferred revenue and an increase in the number of tons transloaded at our Kingfisher Facility. We generally charge our customers a throughput fee for providing rail-to-truck transloading and high-efficiency sand silo storage and transloading services in relation to proppant and chemicals delivered to the Kingfisher Facility.

Inventory Software Services Revenue. Our inventory software services revenue, which decreased $0.1 million, or 14% to $0.5 million for the three months ended March 31, 2019 compared to $0.7 million for the three months ended March 31, 2018, is related to Railtronix inventory management software. We generally charge our customers a throughput fee to monitor proppant that is loaded into a railcar, stored at a transload facility or loaded into a truck.

Operating Expenses

Total operating costs and expenses for the three months ended March 31, 2019 and 2018 were $27.4 million and $20.5 million, respectively, which represented 50% and 57% of total revenue, respectively. Total operating costs and expenses increased year-over-year primarily as a result of the deployment of additional systems to our customers and services thereof, coupled with the related increase in depreciation and amortization expense. Total operating costs as a percentage of total revenue decreased as a result of economies of scale in our operations. Additional details regarding the changes in operating expenses are presented below.

Cost of System Rental (excluding depreciation and amortization). Cost of system rental increased $0.9 million, or 64%, to $2.3 million for the three months ended March 31, 2019 compared to $1.4 million for the three months ended March 31, 2018, excluding depreciation and amortization expense. Cost of system rental as a percentage of system rental revenue was 6% and 5% for the three months ended March 31, 2019 and 2018, respectively. Cost of system rental increased primarily due to an increase in the number of systems that were deployed to customers. The average number of systems deployed to customers increased to 114.7 systems in the three months ended March 31, 2019 from 85.2 systems in the three months ended March 31, 2018.

Cost of system rental including depreciation and amortization expense increased $3.5 million, or 85%, to $7.6 million for the three months ended March 31, 2019 compared to $4.1 million for the three months ended March 31, 2018. This increase was primarily attributable to the increase in systems that were deployed to customers and an increase in depreciation expense related to the additional systems that were manufactured and added to our fleet.

Cost of System Services (excluding depreciation and amortization). Cost of system services increased $4.5 million, or 49%, to $13.6 million for the three months ended March 31, 2019 compared to $9.1 million for the three months ended March 31, 2018. This increase was primarily due to an increase in the number of systems deployed to customers as referenced above, which resulted in an increase in field labor and related costs of $2.5 million, coupled with increased third-party trucking services of $1.9 million to transport incremental systems deployed to customers. The increase in field labor and related costs was driven by an increase in the number of field technicians required to support the increased number of systems deployed during the three months ended March 31, 2019. Cost of system services also increased in relation to services provided to coordinate proppant and chemicals delivered to systems. For the three months ended March 31, 2019, the cost of system services as a percentage of system services revenue decreased to 119% compared to 121% for the three months ended March 31, 2018.

Cost of system services including depreciation and amortization expense increased $4.7 million, or 50%, to $14.0 million for the three months ended March 31, 2019 compared to $9.3 million for the three months ended March 31, 2018. This increase was primarily attributable to the factors mentioned above, as well as an increase in depreciation expense related to additional light-duty field trucks that we purchased to support our increased activity.

Cost of Transloading Services (excluding depreciation and amortization). Cost of transloading services increased $0.4 million, or 133%, to $0.7 million for the three months ended March 31, 2019 compared to $0.3 million for the three

Table of Contents

months ended March 31, 2018 primarily due to increases in direct labor costs, fuel, utilities and maintenance related to increased transloading services activity at our Kingfisher Facility.

Cost of transloading services including depreciation and amortization expense increased $0.8 million, or 232%, to $1.1 million for the three months ended March 31, 2019 compared to $0.3 million for the three months ended March 31, 2018 due to depreciation expense related to transloading facility and equipment, which commenced upon completion of the construction of the Kingfisher Facility in the third quarter of 2018.

Cost of Inventory Software Services (excluding depreciation and amortization). Cost of inventory software services, which decreased $0.1 million, or 33%, to $0.1 million for the three months ended March 31, 2019 compared to $0.3 million for the three months ended March 31, 2018, primarily includes labor and software subscription costs related to Railtronix inventory management software.

Cost of inventory software services including depreciation and amortization expense decreased $0.1 million, or 33%, to $0.3 million for the three months ended March 31, 2019 compared to $0.4 million for the three months ended March 31, 2018. This decrease was primarily attributable to the labor and software subscription costs. Amortization consists of customer relationships, a non-competition agreement and software acquired in the acquisition of Railtronix.

Depreciation and Amortization. Depreciation and amortization increased $3.1 million, or 97%, to $6.3 million for the three months ended March 31, 2019 compared to $3.2 million for the three months ended March 31, 2018. This increase was primarily attributable to additional depreciation expense related to additional systems that were manufactured and added to our fleet and our transloading facility and equipment placed in service in 2018.

Salaries, Benefits and Payroll Taxes. Salaries, benefits and payroll taxes decreased $0.3 million, or 12%, to $2.3 million for the three months ended March 31, 2019 compared to $2.6 million for the three months ended March 31, 2018. The decrease was driven by a decrease in stock-based compensation expense of $0.6 million primarily due to the vesting in 2018 of restricted stock awards that were granted to certain employees and consultants in connection with the IPO with one-year vesting terms. This decrease was partially offset by corporate personnel additions of $0.3 million to support public company and growth needs.

Selling, General and Administrative Expenses (excluding depreciation and amortization). Selling, general and administrative expenses decreased $0.2 million, or 11%, to $1.7 million for the three months ended March 31, 2019 compared to $1.9 million for the three months ended March 31, 2018 due primarily to a decrease of $0.1 million in professional fees.

Other Operating Expenses. Other operating expenses decreased $1.5 million, or 88%, to $0.2 million for the three months ended March 31, 2019 compared to $1.7 million for the three months ended March 31, 2018. Other operating expenses in the three months ended March 31, 2019 were related to $0.2 loss on disposal of assets. Other operating expenses in the three months ended March 31, 2018 were primarily related to certain performance-based cash awards totaling $1.7 million in connection with the purchase of Railtronix upon the achievement of certain financial milestones.

Provision for Income Taxes. During the three months ended March 31, 2019, we recognized a combined United States federal and state provision for income taxes of $4.2 million, an increase of $2.2 million as compared to $2.0 million we recognized during the three months ended March 31, 2018. This increase was attributable to higher operating income.

Net Income

Net income increased $10.0 million to $23.4 million for the three months ended March 31, 2019 compared to $13.4 million for the three months ended March 31, 2018, due to the changes in revenues and expenses discussed above.

Comparison of Non-GAAP Financial Measures

Table of Contents

franchise taxes. We define Adjusted EBITDA as EBITDA plus (i) stock-based compensation expense and (ii) certain non-cash items and any extraordinary, unusual or non-recurring gains, losses or expenses.

We believe that our presentation of EBITDA and Adjusted EBITDA will provide useful information to investors in assessing our financial condition and results of operations. Net income is the GAAP measure most directly comparable to EBITDA and Adjusted EBITDA. EBITDA and Adjusted EBITDA should not be considered alternatives to net income presented in accordance with GAAP. Because EBITDA and Adjusted EBITDA may be defined differently by other companies in our industry, our definitions of EBITDA and Adjusted EBITDA may not be comparable to similarly titled measures of other companies, thereby diminishing their utility. The following table presents a reconciliation of Net income to EBITDA and Adjusted EBITDA for each of the periods indicated.

Three Months Ended March 31, 2019 Compared to Three Months Ended March 31, 2018: EBITDA and Adjusted EBITDA

EBITDA increased $15.3 million to $34.1 million for the three months ended March 31, 2019 compared to $18.7 million for the three months ended March 31, 2018. Adjusted EBITDA increased $13.2 million to $35.1 million for the three months ended March 31, 2019 compared to $21.9 million for the three months ended March 31, 2018. EBITDA and Adjusted EBITDA increased 82% and 60% for the three months ended March 31, 2019 compared to the three months ended March 31, 2018, respectively. The increases were primarily due to an increase in the number of systems deployed to customers due to increasing demand for our systems and enhancements to our product offering.

Liquidity and Capital Resources

Overview

Our primary sources of liquidity to date have been capital contributions from our founding investors, cash flows from operations, borrowings under our credit agreements and proceeds from the IPO and the November 2017 Offering (as defined below). Our primary uses of capital have been capital expenditures to expand our proppant and chemical management system fleets, construction of the Kingfisher Facility, the acquisition of our manufacturing facility and certain intellectual property and the acquisition of the assets of Railtronix. We strive to maintain financial flexibility and proactively monitor potential capital sources, including equity and debt financing, to meet our investment and target liquidity requirements and to permit us to manage the cyclicality associated with our industry.

During 2017, Solaris Inc. completed two public offerings, the IPO, in which Solaris Inc. sold 10,100,000 shares of its Class A common stock par value $0.01 per share, to the public, and a follow-on offering on November 14, 2017 of 7,000,000 shares of its Class A common stock, including 3,000,000 shares issued and sold by the Company and an aggregate of 4,000,000 shares sold by certain stockholders of the Company (the “November 2017 Offering”). On November 13, 2017 the underwriters for the November 2017 Offering exercised in full their option to purchase an aggregate of 1,050,000 additional shares of Class A common stock from the selling stockholders. After deducting underwriting discounts and commissions and offering expenses payable by Solaris Inc., Solaris Inc. received net proceeds of approximately $113.9 million and $44.5 million from the IPO and November 2017 Offering, respectively. Solaris Inc. contributed all of the net proceeds of the IPO and November 2017 Offering to Solaris LLC in exchange for Solaris LLC Units. Solaris LLC used the net proceeds from the IPO (i) to fully repay our existing balance of approximately $5.5 million under its credit facility, (ii) to pay $3.1 million in cash bonuses to certain employees and consultants and (iii) to distribute approximately $25.8 million to certain of our officers and directors and other members of Solaris LLC as partial consideration for the recapitalization of their membership interests in Solaris LLC in connection with the IPO. Solaris LLC has used a portion of the proceeds from the IPO and all of the proceeds from the November 2017 Offering for general corporate purposes, including funding our 2018 capital program.

On October 9, 2018, Solaris Inc. filed a universal shelf registration statement on Form S-3 (the “Universal Shelf”) with the SEC. Under the Universal Shelf, Solaris Inc. may offer and sell up to $500 million of Class A common stock, preferred stock, debt securities or any combination of such securities during the three-year period that commenced upon the Universal Shelf becoming effective on October 16, 2018. Additionally, certain stockholders of the Company (the “Selling Stockholders”) may offer and sell up to an aggregate of 18,366,612 shares of Class A common stock under the Universal Shelf. Under the Universal Shelf, Solaris Inc. may periodically offer one or more types of securities in amounts, at prices and on terms announced, if and when the securities are ever offered. Solaris Inc. expects to contribute net proceeds, if any, from an offering under the Universal Shelf to Solaris LLC for general corporate purposes, including to fund the Company’s capital program. Solaris Inc. will not receive any proceeds, if any, from the sale of shares of Class A common stock by the Selling Stockholders. The Selling Stockholders have subsequently sold 2,279,655 shares of Class A common stock pursuant to an exemption under Rule 144 of the Securities Act, and as of March 31, 2019, 16,086,957 shares of Class A common stock remain available to offer and sell under the Universal Shelf.

We intend to finance most of our capital expenditures, contractual obligations and working capital needs with our current cash balance, cash generated from future operations and borrowings under our 2019 Credit Agreement (as defined in “—Debt Agreements”). We continuously evaluate our capital expenditures and the amount we ultimately spend will depend on a number of factors, including expected industry activity levels and company initiatives. We believe that our operating cash flow and available borrowings under our 2019 Credit Agreement will be sufficient to fund our operations for at least the next 12 months.

As of March 31, 2019, cash totaled $9.4 million.

Analysis of Cash Flow Changes for Three Months Ended March 31, 2019 Compared to Three Months Ended March 31, 2018

Operating Activities. Net cash provided by operating activities was $23.0 million for the three months ended March 31, 2019, compared to net cash provided by operating activities of $4.4 million for the three months ended March 31, 2018. The increase of $18.6 million in operating cash flow was primarily attributable to an increase in net income of $10.0 million primarily due to an increase in the number of systems deployed to customers due to increasing demand for our systems and enhancements to our product offering, as well as an increase in non-cash and working capital items.

Investing Activities . Net cash used in investing activities was $20.3 million for the three months ended March 31, 2019, compared to $41.2 million for the three months ended March 31, 2018. The decrease in investing activities of $20.8 million is primarily due to a decrease in the manufacturing rate of new proppant systems and completion of construction of the Kingfisher Facility in the third quarter of 2018. For the three months ended March 31, 2019, $20.3 million of investing activities were capital expenditures related to manufacturing new systems, including work in process. For the three months ended March 31, 2018, $34.9 million of investing activities were capital expenditures related to manufacturing new systems, $10.7 million related to the construction of our Kingfisher Facility and $1.1 million related to the purchase of light duty vehicles to support the service of our systems.

Financing Activities. Net cash used in financing activities of $18.4 million for the three months ended March 31, 2019, compared to $0.3 million for the three months ended March 31, 2018. The increase in financing activities of $18.1 million was primarily related to $13.0 million to repay borrowings under the 2018 Credit Agreement (as defined in “—Debt Agreements”) and $4.8 million for quarterly dividends. Net cash used in financing activities of $0.3 million for the three months ended March 31, 2018 was primarily related to $1.0 million in debt issuance costs in connection with the 2018 Credit Agreement (as defined in “—Debt Agreements”), partially offset by $0.7 million proceeds received from the exercise of stock options.

Debt Agreements

Senior Secured Credit Facility

On January 19, 2018, we entered into a credit agreement (the “2018 Credit Agreement”) by and among the Company, as borrower, each of the lenders party thereto and Woodforest National Bank, as administrative agent (the “2018 Credit Agreement Administrative Agent”). The 2018 Credit Agreement replaced, in its entirety, the Company’s prior credit facility, as amended on May 17, 2017, by and among the Company, as borrower, each of the lenders party thereto and the 2018 Credit Agreement Administrative Agent. The 2018 Credit Agreement consisted of a $50.0 million advancing term loan (the “Advance Loan”) and a $20.0 million revolving loan, with a $10.0 million uncommitted accordion option to increase the total revolving loans (the “Revolving Loan”, and together with the Advance Loan, the “Loans”). No lender had any obligation to increase its own revolving credit commitment. The Advance Loan amortized beginning in April 2019 and each of the Loans matured on January 19, 2022. Our obligations under the Loans were generally secured by a pledge of substantially all of the assets of the Company and its subsidiaries, and such obligations were guaranteed by our domestic subsidiaries other than Immaterial Subsidiaries (as defined in the 2018 Credit Agreement). We had the option to prepay the loans at any time without penalty.

Table of Contents

As of March 31, 2019, we had no borrowings under the 2018 Credit Agreement outstanding.

The 2018 Credit Agreement required that we maintain ratios of (a) indebtedness to consolidated EBITDA of not more than 3.50 to 1.00, which stepped down to 3.25 to 1.00 beginning April 1, 2018 and 3.00 to 1.00 beginning October 1, 2018, and (b) senior indebtedness to consolidated EBITDA of not more than 2.50 to 1.00, which stepped down to 2.25 to 1.00 beginning April 1, 2018 and 2.00 to 1.00 beginning October 1, 2018. For the purpose of these tests, there was subtracted from indebtedness and senior indebtedness, respectively, an amount equal to the lesser of $10.0 million or 50% of unrestricted cash and cash equivalents of the Company and its subsidiaries. EBITDA, as defined in the 2018 Credit Agreement, excluded certain noncash items and any extraordinary, unusual or non-recurring gains, losses or expenses.

The 2018 Credit Agreement also required that we maintain a ratio of consolidated EBITDA to fixed charges of not less than 1.25 to 1.00. Capital Expenditures were permitted up to $75.0 million for fiscal year ending December 31, 2019 and each fiscal year thereafter. In addition, for fiscal years beginning on January 1, 2020, any unused availability for capital expenditures from the immediately preceding fiscal year may be carried forward to the subsequent year; provided, however that we were permitted to make any capital expenditures in an amount equal to the proceeds of equity contributions made to the Company used to fund such capital expenditures.

As of March 31, 2019, we were in compliance will all covenants in accordance with the 2018 Credit Agreement.

Income Taxes

Solaris Inc. is a corporation and, as a result, is subject to United States federal, state and local income taxes. For the three months ended March 31, 2019, we recognized a combined United States federal and state provision for income taxes of $4.2 million and $2.0 million, respectively.

Solaris LLC is treated as a partnership for United States federal income tax purposes and therefore does not pay federal income tax on its taxable income. Instead, the Solaris LLC members are liable for United States federal income tax on their respective shares of the Company’s taxable income reported on the members’ United States federal income tax returns.

Table of Contents

We are subject to a franchise tax imposed by the State of Texas. The franchise tax rate is 1%, calculated on taxable margin. Taxable margin is defined as total revenue less deductions for cost of goods sold or compensation and benefits in which the total calculated taxable margin cannot exceed 70% of total revenue. Expenses related to Texas franchise tax were approximately $189,000 and $121,000 for the three months ended March 31, 2019 and 2018, respectively.

We account for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events included in the consolidated financial statements. Under this method, we determine deferred tax assets and liabilities on the basis of the differences between the book value and tax bases of assets and liabilities by using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period in which the enactment date occurs.

We record uncertain tax positions on the basis of a two-step process in which (1) we determine whether it is more-likely-than-not the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions meeting the more-likely-than-not recognition threshold, we recognize the largest amount of tax benefit that is more than 50% likely to be realized upon ultimate settlement with the related tax authority. For the three months ended March 31, 2019, the Company has recorded an uncertain tax benefit for the treatment of certain costs incurred in connection with the IPO and the November 2017 Offering.

Interest and penalties related to income taxes are included in the benefit (provision) for income taxes in our consolidated statement of operations. We have not incurred any significant interest or penalties related to income taxes in any of the periods presented.

See Note 9. “Income Taxes” to our condensed consolidated financial statements for additional information.

Payables Related to the Tax Receivable Agreement

In connection with the IPO, Solaris Inc. entered into the Tax Receivable Agreement with the TRA Holders on May 17, 2017. This agreement generally provides for the payment by Solaris Inc. to each TRA Holder of 85% of the net cash savings, if any, in United States federal, state and local income tax and franchise tax that Solaris Inc. actually realizes (computed using simplifying assumptions to address the impact of state and local taxes) or is deemed to realize in certain circumstances in periods after the IPO as a result of (i) certain increases in tax basis that occur as a result of Solaris Inc.’s acquisition (or deemed acquisition for United States federal income tax purposes) of all or a portion of such TRA Holder's Solaris LLC Units in connection with the IPO or pursuant to the exercise of the Redemption Right or the Call Right (each as defined in the Solaris LLC’s Second Amended and Restated Limited Liability Company Agreement (the “Solaris LLC Agreement”)) and (ii) imputed interest deemed to be paid by Solaris Inc. as a result of, and additional tax basis arising from, any payments Solaris Inc. makes under the Tax Receivable Agreement. Solaris Inc. will retain the benefit of the remaining 15% of these cash savings.

See Note 9. “Income Taxes” to our condensed consolidated financial statements for additional information.

Critical Accounting Policies and Estimates

The preparation of financial statements requires the use of judgments and estimates. Our critical accounting policies are described below to provide a better understanding of how we develop our assumptions and judgments about future events and related estimates and how they can impact our financial statements. A critical accounting estimate is one that

Table of Contents

requires our most difficult, subjective or complex estimates and assessments and is fundamental to our results of operations.

We base our estimates on historical experience and on various other assumptions we believe to be reasonable according to the current facts and circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. We believe the following are the critical accounting policies used in the preparation of our combined financial statements, as well as the significant estimates and judgments affecting the application of these policies. This discussion and analysis should be read in conjunction with our condensed consolidated financial statements and related notes included in this report.

Revenue Recognition

Table of Contents

below minimum throughput volumes required. The Company recorded $474 of shortfall revenue during the three months ended March 31, 2019.

Deferred Revenue

Deferred revenue consists of a $25,980 partial termination payment fee received in December 2018 in accordance with a contract modification which is accounted for prospectively. The partial termination payment fee represents the distinct unsatisfied portion of a contract to provide transloading services and are considered part of the transaction price and will be allocated to the remaining performance obligations under the contract. Deferred revenues in the condensed consolidated balance sheets were $22,323 and $25,458 as of March 31, 2019 and December 31, 2018, respectively, which will be recognized as Revenue from transloading services over the remaining two-year term of the modified agreement. The Company recognized $3,134 of deferred revenue as Revenue from transloading services in the condensed consolidated statements of operations for the three months ended March 31, 2019. No deferred revenue was recorded or recognized as revenue during the three months ended March 31, 2018.

Unbilled Receivables

Property, Plant and Equipment

Property, plant and equipment are stated at cost, or fair value for assets acquired, less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful service lives of the assets. Systems that are in the process of being manufactured are considered property, plant and equipment. However, the systems in process do not depreciate until they are fully completed. Systems in process are a culmination of material, labor and overhead.

The costs of ordinary repairs and maintenance are charged to expense as incurred, while significant enhancements, including upgrades or overhauls, are capitalized. These enhancements include upgrades to various components of the system and to equipment at our manufacturing facility that will either extend the life or improve the utility and efficiency of the systems, plant and equipment. These enhancements include:

Our patented Auto Hopper technology is being added to our proppant systems and is compatible with standard pressure pumping company’s equipment. The technology uses sensors and machine learning to automatically control the amount of sand delivered from our mobile proppant management system silos to the blender, eliminating the need for dedicated personnel historically required to run our system.

Our patent-pending mobile chemical management system can store and deliver up to six different chemicals with significantly improved inventory control, in a smaller footprint and with less personnel when compared to traditional chemical handling methods.

Our patent-pending non-pneumatic loading option provides additional proppant transportation flexibility for our customers, allowing them to use belly-dump trucks in addition to the industry standard pneumatic trucks to fill and maintain inventory in our proppant management systems. This patent-pending non-pneumatic loading option is compatible with our existing fleet with minimal modification.

Manufacturing plant improvements include upgrades to overhead cranes and the addition of new column bays and trunnions that improve the manufacturing flow, as well as improvements in the paint booths. These improvements increase productivity by reducing labor hours, while improving safety.

Table of Contents

The determination of whether an expenditure should be capitalized or expensed requires management judgment in the application of how the costs benefit future periods, relative to our capitalization policy. Costs that increase the value or materially extend the life of the asset are capitalized and depreciated over the remaining useful life of the asset. When property and equipment are sold or retired, the cost and related accumulated depreciation are removed from the accounts and any gain or loss is reflected in the consolidated statements of operations.

Allocation of Purchase Price in Business Combinations

As part of our business strategy, we regularly pursue acquisition and business development opportunities. The purchase price in an acquisition is allocated to the assets acquired and liabilities assumed based on their fair values as of the closing date, which may occur many months after the announcement date. The excess of the purchase price over the amount allocated to the assets and liabilities, if any, is recorded as goodwill. We use all available information to estimate fair values including quoted market prices, the carrying value of acquired assets, and widely accepted valuation techniques such as discounted cash flows. Our most significant estimates in our allocation typically relate to the value assigned to property, plant and equipment, intangible assets and goodwill. The judgments made in determining the estimated fair value assigned to each class of assets acquired and liabilities assumed, as well as asset lives, could materially impact our results of operations.

Impairment of Long-Lived and Other Intangible Assets

Long-lived assets, which include property, plant and equipment and identified intangible assets, comprise a significant amount of our total assets. We make judgments and estimates in conjunction with the carrying value of these assets, including amounts to be capitalized, depreciation and amortization methods, estimated useful lives and impairment.

The carrying values of these assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amounts may not be recoverable. An impairment loss is recorded in the period in which it is determined that the carrying amount is not recoverable based on estimated future undiscounted cash flows. We estimate the fair value of these intangible and fixed assets using an income approach. This requires us to make long-term forecasts of its future revenues and costs related to the assets subject to review. These forecasts require assumptions about demand for the Company’s products and services, future market conditions and technological developments. The financial and credit market volatility directly impacts our fair value measurement through our income forecast. Although we have made our best estimates of these factors based on current conditions, it is reasonably possible that changes could occur in the near term, including, but not limited to: sustained declines in worldwide rig counts below current analysts’ forecasts, collapse of spot and futures prices for oil and natural gas, significant deterioration of external financing for our customers, higher risk premiums or higher cost of equity, or any other significant adverse economic news, which could adversely affect our estimates requiring a provision for impairment.

There was no impairment for the three months ended March 31, 2019 and 2018.

Leases

The Company accounts for leases in accordance with Accounting Standards Codification (“ASC”) Topic 842, Leases (“ASC Topic 842”), which the Company adopted effective January 1, 2019. The Company applied ASC Topic 842 to all leases existing at or commencing after January 1, 2019 and elected the package of transition practical expedients for expired or existing contracts, which does not require reassessment of: (1) whether any of our contracts are or contain leases, (2) lease classification and (3) initial direct costs. The Company also elected the practical expedient to adopt the new lease requirements through a cumulative effect adjustment in the period of adoption. As a result of the adoption of ASC Topic 842 on January 1, 2019, the Company recorded operating ROU assets of $8,503, operating lease liabilities of $9,016 and a cumulative effect adjustment to retained earnings for operating leases of $532.

in the Company’s condensed consolidated balance sheets. Finance leases are included in property and equipment, current portion of finance lease liabilities, and finance lease liabilities, net of current in the Company’s condensed consolidated balance sheets.

Goodwill

Goodwill represents the excess of the purchase price of acquisitions, or fair value of contributed assets, over the fair value of the net assets acquired and consists of synergies in combining operations and other intangible assets which do not qualify for separate recognition. We evaluate goodwill for impairment annually, as of October 31, or more often as facts and circumstances warrant. The recoverability of the carrying value is assessed based on expected future profitability and undiscounted future cash flows of the acquisitions and their contribution to our overall operations. These types of analyses contain uncertainties because they require us to make judgments and assumptions regarding future profitability, industry factors, planned strategic initiatives, discount rates and other factors. Events or circumstances which could indicate a potential impairment include (but are not limited to) a significant sustained reduction in worldwide oil and natural gas prices or drilling; a significant sustained reduction in profitability or cash flow of oil and natural gas companies or drilling contractors; a sustained reduction in the market capitalization of the Company; a significant sustained reduction in capital investment by drilling companies and oil and natural gas companies; or a significant sustained increase in worldwide inventories of oil or natural gas. There was no impairment for the three months ended March 31, 2019 and 2018.

Stock-Based Awards

We follow the fair value recognition provisions in accordance with GAAP. Under the fair value recognition provisions, stock-based compensation cost is measured at the grant date based on the fair value of the award and is amortized to compensation expense on a straight-line basis over the awards’ vesting period, which is generally the requisite service period. We have historically and consistently calculated fair value using the Black-Scholes option-pricing model. This valuation approach involves significant judgments and estimates, including estimates regarding our future operations, price variation and the appropriate risk-free rate of return. Our estimates of these variables are made for the purpose of using the valuation model to determine an expense for each reporting period and are not subsequently adjusted. We recognize expense related to the estimated vesting of our performance share units granted.

Income Taxes

We routinely evaluate the realizability of our deferred tax assets by assessing the likelihood that our deferred tax assets will be recovered based on all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, estimates of future taxable income, tax planning strategies and results of operations. Estimating future taxable income is inherently uncertain and requires judgment. In projecting future taxable income, we consider our historical results and incorporate certain assumptions, including revenue growth and operating margins, among others. As of March 31, 2019 and December 31, 2018, we had $25.3 million and $24.6 million of deferred tax assets, respectively. We expect to realize future tax benefits related to the utilization of these assets. If we determine in the future that we will not be able to fully utilize all or part of these deferred tax assets, we would record a valuation allowance through earnings in the period the determination was made, which would have an adverse effect on our results of operations and earnings in future periods.

Payables Related to the Tax Receivable Agreement

As described in Note 9. “Income Taxes” to our condensed consolidated financial statements, we are a party to the Tax Receivable Agreement under which we are contractually committed to pay the TRA Holders 85% of the calculated net cash savings in United States federal, state and local income tax and franchise tax that Solaris Inc. anticipates realizing in future years from certain increases in tax basis and certain tax benefits attributable to imputed interest as a result of Solaris Inc.’s acquisition (or deemed acquisition for United States federal income tax purposes) of Solaris LLC Units in connection with the IPO or pursuant to an exercise of the Redemption Right or the Call Right (each as defined in the Solaris LLC Agreement).

The projection of future taxable income involves significant judgment. Actual taxable income may differ from our estimates, which could significantly impact our liability under the Tax Receivable Agreement. We have determined it is more-likely-than not that we will be able to utilize all of our deferred tax assets subject to the Tax Receivable Agreement; therefore, we have recorded a liability under the Tax Receivable Agreement related to the tax savings we may realize from certain increases in tax basis and certain tax benefits attributable to imputed interest as a result of Solaris Inc.’s acquisition (or deemed acquisition for United States federal income tax purposes) of Solaris LLC Units in connection with the IPO or pursuant to an exercise of the Redemption Right or the Call Right (each as defined in the Solaris LLC Agreement). If we determine the utilization of these deferred tax assets is not more-likely-than-not in the future, our estimate of amounts to be paid under the Tax Receivable Agreement would be reduced. In this scenario, the reduction of the liability under the Tax Receivable Agreement would result in a benefit to our condensed consolidated statement of operations.

Recent Accounting Pronouncements

See Note 2. “Summary of Significant Accounting Policies – Accounting Standards Recently Adopted” to our condensed consolidated financial statements as of March 31, 2019, for a discussion of recent accounting pronouncements.

Under the Jumpstart Our Business Startups Act (the “JOBS Act”), we meet the definition of an “emerging growth company,” which allows us to have an extended transition period for complying with new or revised accounting standards pursuant to Section 107(b) of the JOBS Act, however, we elected to opt out of such exemption (this election is irrevocable).

Off Balance Sheet Arrangements

We have no material off balance sheet arrangements. As such, we are not materially exposed to any financing, liquidity, market or credit risk that could arise if we had engaged in such financing arrangements.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

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

Commodity Price Risk

The market for our services is indirectly exposed to fluctuations in the prices of crude oil and natural gas to the extent such fluctuations impact drilling and completion activity levels and thus impact the activity levels of our customers in the exploration and production and oilfield services industries. We do not currently intend to hedge our indirect exposure to commodity price risk.

Table of Contents

Interest Rate Risk

We are subject to interest rate risk on a portion of our long-term debt under the 2019 Credit Agreement. We do not currently have any borrowings under the 2019 Credit Agreement.

Credit Risk

The majority of our accounts receivable have payment terms of 60 days or less. As of March 31, 2019, three customers collectively accounted for 47% of our total accounts receivable. As of December 31, 2018, three customers collectively accounted for 40% of our total accounts receivable. We mitigate the associated credit risk by performing credit evaluations and monitoring the payment patterns of our customers.

Item 4. Controls and Procedures

In accordance with Exchange Act Rules 13a-15 and 15d-15, we have evaluated, under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) as of March 31, 2019. Our disclosure controls and procedures are designed to provide reasonable assurance that the information required to be disclosed by us in reports that we file or submit under the Exchange Act is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure and is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC. Based upon that evaluation, our principal executive officer and principal financial officer concluded that our disclosure controls and procedures were effective as of March 31, 2019 at the reasonable assurance level.

Changes in Internal Control over Financial Reporting

There were no changes in our system of internal control over financial reporting (as defined in Rule 13a-15(f) and Rule 15d-15(f) under the Exchange Act) during the quarter ended March 31, 2019 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Item 5. Other Information

On April 26, 2019, we entered into the 2019 Credit Agreement by and among the Company, as borrower, each of the lenders party thereto and Wells Fargo Bank, National Association, as administrative agent. The 2019 Credit Agreement replaced, in its entirety, the Company’s 2018 Credit Agreement. The 2019 Credit Agreement consists of an

Table of Contents

initial $50,000,000 revolving loan commitment (the “Loan”) with a $25,000,000 uncommitted accordion option to increase the Loan availability to $75,000,000. The term of the 2019 Credit Agreement expires on April 26, 2022.

Our obligations under the Loan are generally secured by a pledge of substantially all of the assets of the Company and its subsidiaries, and such obligations are guaranteed by our domestic subsidiaries other than Immaterial Subsidiaries (as defined in the 2019 Credit Agreement). We have the option to prepay the loans at any time without penalty.

Borrowings under the 2019 Credit Agreement bear interest at either LIBOR or an alternate base rate plus an applicable margin, and interest is payable quarterly. The applicable margin ranges from 1.75% to 2.50% for eurodollar loans and 0.75% to 1.50% for alternate base rate loans, in each case depending on our total leverage ratio. The 2019 Credit Agreement requires that we pay a quarterly commitment fee on undrawn amounts of the Loan, ranging from 0.25% to 0.375% depending upon the total leverage ratio.

The 2019 Credit Agreement requires that we maintain ratios of (a) consolidated EBITDA to interest expense of not less than 2.75 to 1.00, (b) senior indebtedness to consolidated EBITDA of not more than 2.50 to 1.00 and (c) the sum of 100% of eligible accounts, inventory and fixed assets to the total revolving exposure of not less than 1.00 to 1.00 when the total leverage ratio is greater than 2.00 to 1.00 and total revolving exposure under the Loan exceeds $3,000,000. For the purpose of these tests, certain items are subtracted from indebtedness and senior indebtedness. EBITDA, as defined in the 2019 Credit Agreement, excludes certain noncash items and any extraordinary, unusual or non-recurring gains, losses or expenses.

The 2019 Credit Agreement also requires that we prepay any outstanding borrowings under the Loan in the event our total leverage ratio is greater than 1.00 to 1.00 and our consolidated cash balance exceeds $20,000,000, taking into account certain adjustments. Capital expenditures are not restricted unless borrowings under the Loan exceed $5,000,000 for any 180 consecutive day period, in which case capital expenditures will be permitted up to $100,000,000 plus any unused availability for capital expenditures from the immediately preceding fiscal year.

As of April 30, 2019, we had no borrowings under the 2019 Credit Agreement outstanding.

AMENDED AND RESTATED CREDIT AGREEMENT

This AMENDED AND RESTATED CREDIT AGREEMENT (as amended, modified, restated, supplemented and in effect from time to time, herein called this “ Agreement ”) dated as of April 26, 2019 (the “ Effective Date ”), among SOLARIS OILFIELD INFRASTRUCTURE, LLC, a Delaware limited liability company, as borrower, the lenders from time to time party hereto (the “ Lenders ”), and WELL FARGO BANK, NATIONAL ASSOCIATION, as administrative agent for the Lenders and Issuing Bank.

If the Commitments have terminated or expired, the Applicable Percentages shall be determined based upon the Commitments most recently in effect, giving effect to any assignments and to any Lender’s status as a Defaulting Lender at the time of determination.

“ Applicable Rate ” means, for any day with respect to any Loan, the applicable rate per annum set forth below based upon the Total Leverage Ratio as of the most recent determination date; but for the period beginning with the Effective Date and ending on the date the Applicable Rate is redetermined in accordance with the provisions set forth below, Category 1 shall be applicable:

In consideration and in furtherance of the foregoing, each Lender hereby absolutely and

unconditionally agrees to pay to the Administrative Agent, for the account of the Issuing Bank, such Lender’s Applicable Percentage of each LC Disbursement made by the Issuing Bank and not reimbursed by the Borrower on the date due as provided in Section 2.04(e) , or of any reimbursement payment required to be refunded to the Borrower for any reason. Each Lender acknowledges and agrees that its obligation to acquire participations pursuant to this Section 2.04(d) in respect of Letters of Credit is absolute and unconditional and shall not be affected by any circumstance whatsoever, including any amendment, renewal or extension of any Letter of Credit or the occurrence and continuance of a Default or reduction or termination of the Commitments, and that each such payment shall be made without any offset, abatement, withholding or reduction whatsoever.

(e) Reimbursement . If the Issuing Bank shall make any LC Disbursement in respect of a Letter of Credit, the Borrower shall reimburse such LC Disbursement by paying to the Administrative Agent an amount equal to such LC Disbursement not later than 2:00 p.m., Houston, Texas time, on the date that such LC Disbursement is made, if the Borrower shall have received notice of such LC Disbursement prior to 10:00 a.m., Houston, Texas time, on such date, or, if such notice has not been received by the Borrower prior to such time on such date, then not later than 2:00 p.m., Houston, Texas time, on the Business Day immediately following the day that the Borrower receives such notice; provided that, subject to the conditions to borrowing set forth in Section 4.03 of this Agreement, if the Borrower does not so reimburse the Issuing Bank by such time, the Borrower shall be deemed to have requested in accordance with Section 2.03 of this Agreement that such payment be financed with an ABR Borrowing in an equivalent amount and, to the extent so financed, the Borrower’s obligation to make such payment shall be discharged and replaced by the resulting ABR Borrowing. If the Borrower fails to make such payment when due, the Administrative Agent shall notify each Lender of the applicable LC Disbursement, the payment then due from the Borrower in respect thereof and such Lender’s Applicable Percentage thereof. Promptly following receipt of such notice, each Lender shall pay to the Administrative Agent its Applicable Percentage of the payment then due from the Borrower, in the same manner as provided in Section 2.05 with respect to Loans made by such Lender (and Section 2.05 shall apply, mutatis mutandis, to the payment obligations of the Lenders), and the Administrative Agent shall promptly pay to the Issuing Bank the amounts so received by it from the Lenders. Promptly following receipt by the Administrative Agent of any payment from the Borrower pursuant to this Section 2.04(e) , the Administrative Agent shall distribute such payment to the Issuing Bank or, to the extent that Lenders have made payments pursuant to this Section 2.04(e) to reimburse the Issuing Bank, then to such Lenders and the Issuing Bank as their interests may appear. Any payment made by a Lender pursuant to this Section 2.04(e) to reimburse the Issuing Bank for any LC Disbursement (other than the funding of Loans as contemplated above) shall not constitute a Loan and shall not relieve the Borrower of its obligation to reimburse such LC Disbursement.

The Borrower’s obligation to reimburse LC Disbursements as provided in Section 2.04(e) shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this Agreement under any and all circumstances whatsoever and irrespective of (i) any lack of validity or enforceability of any Letter of Credit or this Agreement, or any term or provision therein, (ii) any draft or other document presented under

a Letter of Credit proving to be forged, fraudulent or invalid in any respect or any statement therein being untrue or inaccurate in any respect, (iii) payment by the Issuing Bank under a Letter of Credit against presentation of a draft or other document that does not comply with the terms of such Letter of Credit, or (iv) any other event or circumstance whatsoever, whether or not similar to any of the foregoing, that might, but for the provisions of this Section, constitute a legal or equitable discharge of, or provide a right of setoff against, the Borrower’s obligations hereunder. Neither the Administrative Agent, the Lenders nor the Issuing Bank, nor any of their Related Parties, shall have any liability or responsibility by reason of or in connection with the issuance or transfer of any Letter of Credit or any payment or failure to make any payment thereunder (irrespective of any of the circumstances referred to in the preceding sentence), or any error, omission, interruption, loss or delay in transmission or delivery of any draft, notice or other communication under or relating to any Letter of Credit (including any document required to make a drawing thereunder), any error in interpretation of technical terms or any consequence arising from causes beyond the control of the Issuing Bank; provided that the foregoing shall not be construed to excuse the Issuing Bank from liability to the Borrower to the extent of any direct damages (as opposed to special, indirect, consequential or punitive damages, claims in respect of which are hereby waived by the Borrower to the extent permitted by applicable law) suffered by the Borrower that are caused by the Issuing Bank’s failure to exercise care when determining whether drafts and other documents presented under a Letter of Credit comply with the terms thereof. The parties hereto expressly agree that, in the absence of gross negligence or willful misconduct on the part of the Issuing Bank (as finally determined by a court of competent jurisdiction), the Issuing Bank shall be deemed to have exercised care in each such determination. In furtherance of the foregoing and without limiting the generality thereof, the parties agree that, with respect to documents presented which appear on their face to be in substantial compliance with the terms of a Letter of Credit, the Issuing Bank may, in its sole discretion, either accept and make payment upon such documents without responsibility for further investigation, regardless of any notice or information to the contrary, or refuse to accept and make payment upon such documents if such documents are not in strict compliance with the terms of such Letter of Credit.

(g) Disbursement Procedures . The Issuing Bank shall, promptly following its receipt thereof, examine all documents purporting to represent a demand for payment under a Letter of Credit. The Issuing Bank shall promptly notify the Administrative Agent and the Borrower by telephone (confirmed by telecopy) of such demand for payment and whether the Issuing Bank has made or will make an LC Disbursement thereunder; provided that any failure to give or delay in giving such notice shall not relieve the Borrower of its obligation to reimburse the Issuing Bank and the Lenders with respect to any such LC Disbursement.

(h) Interim Interest . If the Issuing Bank shall make any LC Disbursement, then, unless the Borrower shall reimburse such LC Disbursement in full on the date such LC Disbursement is made (either with its own funds or a Borrowing under Section 2.04(e) ), the unpaid amount thereof shall bear interest, for each day from and including the date such LC Disbursement is made to but excluding the date that the reimbursement is due and payable at the rate per annum then applicable to ABR Loans and such interest shall be due and payable on the date when such reimbursement is payable; provided that, if the Borrower fails to reimburse such LC Disbursement when due

pursuant to Section 2.04(e) , then Section 2.12(b) shall apply. Interest accrued pursuant to this Section 2.04(h) shall be for the account of the Issuing Bank, except that interest accrued on and after the date of payment by any Lender pursuant to Section 2.04(e) to reimburse the Issuing Bank shall be for the account of such Lender to the extent of such payment.

(i) Replacement of the Issuing Bank . The Issuing Bank may be replaced at any time by written agreement among the Borrower, the Administrative Agent, the replaced Issuing Bank and the successor Issuing Bank.

From and after the effective date of any such replacement, (i) the successor Issuing Bank shall have all the rights and obligations of the Issuing Bank under this Agreement with respect to Letters of Credit to be issued thereafter and (ii) references herein to the term “Issuing Bank” shall be deemed to refer to such successor or to any previous Issuing Bank, or to such successor and all previous Issuing Banks, as the context shall require. After the replacement of an Issuing Bank hereunder, the replaced Issuing Bank shall remain a party hereto and shall continue to have all the rights and obligations of an Issuing Bank under this Agreement with respect to Letters of Credit issued by it prior to such replacement, but shall not be required to issue additional Letters of Credit.

(j) Cash Collateralization . If any Event of Default shall occur and be continuing, on the Business Day that the Borrower receives notice from the Administrative Agent or the Required Lenders (or, if the maturity of the Loans has been accelerated, Lenders with LC Exposure representing greater than 51% of the total LC Exposure) demanding the deposit of cash collateral pursuant to this Section 2.04(j) , the Borrower shall deposit in an account with the Administrative Agent, in the name of the Administrative Agent and for the benefit of the Lenders, an amount in cash equal to the LC Exposure as of such date plus any accrued and unpaid interest thereon; provided that the obligation to deposit such cash collateral shall become effective immediately, and such deposit shall become immediately due and payable, without demand or other notice of any kind, upon the occurrence of any Event of Default described in clauses (g) or (h) of Article VII . The Borrower also shall deposit cash collateral pursuant to this Section 2.04(j) as and to the extent required by Section 2.10(b) . Each such deposit shall be held by the Administrative Agent as collateral for the payment and performance of the obligations of the Borrower under this Agreement.

Other than any interest earned on the investment of such deposits, which investments shall be made (consistent with the goal of preservation of capital) at the option and sole discretion of the Administrative Agent and at the Borrower’s risk and expense, such deposits shall not bear interest. Interest or profits, if any, on such investments shall accumulate in such account. Moneys in such account shall be applied by the Administrative Agent to reimburse the Issuing Bank for LC Disbursements for which it has not been reimbursed and, to the extent not so applied, shall be held for the satisfaction of the reimbursement obligations of the Borrower for the LC Exposure at such time or, if the maturity of the Loans has been accelerated (but subject to the consent of Lenders with LC Exposure representing greater than 51% of the total LC Exposure), be applied to satisfy other obligations of the Borrower under this

Agreement. If the Borrower is required to provide an amount of cash collateral hereunder as a result of the occurrence of an Event of Default, such amount (to the extent not applied as aforesaid) shall be returned to the Borrower within three (3) Business Days after all Events of Default have been cured or waived. If the Borrower is required to provide an amount of cash collateral hereunder pursuant to Section 2.10(b) , such amount (to the extent not applied as aforesaid) shall be returned to the Borrower as and to the extent that, after giving effect to such return, the Borrower would remain in compliance with Section 2.10(b) and no Default shall have occurred and be continuing.

(k) Subject to the appointment and acceptance of a successor Issuing Bank, the Issuing Bank may resign as the Issuing Bank at any time upon thirty days’ prior written notice to the Administrative Agent, the Borrower and the Lenders, in which case, such Issuing Bank shall be replaced in accordance with Section 2.04(i) above.

(b) Interest Election Requests . To make an election pursuant to this Section 2.06 , the Borrower shall notify the Administrative Agent of such election by telephone by the time that a Borrowing Request would be required under Section 2.03 if the Borrower were requesting a Borrowing of the Type resulting from such election to be made on the effective date of such election. Each such telephonic Interest Election Request shall be irrevocable and shall be confirmed promptly by hand delivery, telecopy or other electronic communication to the Administrative Agent of a written Interest Election Request in substantially the form of Exhibit D or otherwise acceptable to the Administrative Agent and signed by the Borrower.

(i) the Borrowing to which such Interest Election Request applies and, if different options are being elected with respect to different portions thereof, the portions thereof to be allocated to each resulting Borrowing (in which case the information to be specified pursuant to Section 2.06(c)(iii) and Section 2.06(c)(iv) shall be specified for each resulting Borrowing);

(ii) the effective date of the election made pursuant to such Interest Election Request, which shall be a Business Day;

(iii) whether the resulting Borrowing is to be an ABR Borrowing or a Eurodollar Borrowing; and

(iv) if the resulting Borrowing is a Eurodollar Borrowing, the Interest Period to be applicable thereto after giving effect to such election, which shall be a period contemplated by the definition of the term “Interest Period”.

If any such Interest Election Request requests a Eurodollar Borrowing but does not specify an Interest Period, then the Borrower shall be deemed to have selected an Interest Period of one month’s duration.

(d) Notice to Lenders by the Administrative Agent . Promptly following receipt of an Interest Election Request, the Administrative Agent shall advise each Lender of the details thereof and of such Lender’s portion of each resulting Borrowing.

(e) Effect of Failure to Delivery Timely Interest Election Request and Events of Default on Interest Election . If the Borrower fails to deliver a timely Interest Election Request with respect to a Eurodollar Borrowing prior to the end of the Interest Period applicable thereto, then, unless such Borrowing is repaid as provided herein, at the end of such Interest Period such Borrowing shall be converted to a Eurodollar Borrowing with an Interest Period of one month. Notwithstanding any contrary provision hereof, if an Event of Default has occurred and is continuing and the Required Lenders have elected in writing to the Administrative Agent to not allow such conversions or continuations, no outstanding Borrowing may be converted to or continued as a Eurodollar Borrowing (and any Interest Election Request that requests the conversion of any Borrowing to, or continuation of any Borrowing as, a Eurodollar Borrowing shall be ineffective) and, unless repaid, each Eurodollar Borrowing shall be converted to an ABR Borrowing at the end of the Interest Period applicable thereto.

SECTION 2.07 Termination, Reduction and Increase of Commitments .

(a) Unless previously terminated, the Commitments shall terminate on the Revolving Maturity Date.

(b) T he Borrower may at any time terminate, or from time to time reduce, the Commitments; provided that (i) each reduction of the Commitments shall be in an amount that is an integral multiple of $500,000 or in the amount of the total Commitments then outstanding and (ii) the Borrower shall not terminate or reduce the Commitments if, after giving effect to any concurrent prepayment of the Loans in accordance with Section 2.10, the Total Revolving Exposure would exceed the total Commitments.

(c) The Borrower shall notify the Administrative Agent of any election to terminate or reduce the Commitments under Section 2.07(b) , at least three (3) Business Days prior to the effective date of such termination or reduction, specifying such election and the effective date thereof. Promptly following receipt of any notice, the Administrative Agent shall advise the Lenders of the contents thereof. Each notice delivered by the Borrower pursuant to this Section shall be irrevocable; provided that a notice of termination of the Commitments delivered by the Borrower may state that such notice is conditioned upon the effectiveness of other credit facilities, in which case such notice may be revoked by the Borrower (by notice to the Administrative Agent on or prior to the specified effective date) if such condition is not satisfied. Any termination or reduction of the Commitments shall be permanent. Each reduction of the Commitments shall be made ratably among the Lenders in accordance with their respective Commitments.

(d) At any time prior to the expiration of the Revolving Availability Period, and so long as no Default or Event of Default shall have occurred which is continuing, the Borrower may elect to increase the aggregate of the Commitments to an amount not exceeding $75,000,000 minus any reductions in the Commitments pursuant to Section 2.07(b) , provided that (i) the Borrower shall give at least fifteen (15) Business Days’ prior written notice of such increase to the Administrative Agent and each existing Lender, (ii) each existing Lender shall have the right (but not the obligation) to subscribe to its pro rata share of the proposed increase in the Commitments by giving

written notice of such election to the Borrower and the Administrative Agent within ten (10) Business Days after receipt of a notice from the Borrower as above described and only if an existing Lender does not exercise such election may the Borrower elect to add a new Lender, (iii) no Lender shall be required to increase its Commitment unless it shall have expressly agreed to such increase in writing, (iv) the addition of new Lenders shall be subject to the terms and provisions of Section 9.04 as if such new Lenders were acquiring an interest in the Loans by assignment from an existing Lender (to the extent applicable, i.e., required approvals, minimum amounts and the like), (v) the Borrower shall execute and deliver such additional or replacement Notes and such other documentation (including evidence of proper authorization) as may be reasonably requested by the Administrative Agent, any new Lender or any Lender which is increasing its Commitment, (vi) no Lender shall have any right to decrease its Commitment as a result of such increase of the aggregate amount of the Commitments, (vii) the Administrative Agent shall have no obligation to arrange, find or locate any Lender or new bank or financial institution to participate in any unsubscribed portion of such increase in the aggregate committed amount of the Commitments, (viii) such option to increase the Commitments may only be exercised twice and (ix) the consent of each Lender increasing its Commitment shall be required for any increase of such Lender’s Commitment (such consent to be given or denied in such increasing Lender’s sole discretion and subject to such terms as such increasing Lender may then require) . The Borrower shall be required to pay (or to reimburse each applicable Lender for) any breakage costs incurred by any Lender in connection with the need to reallocate existing Loans among the Lenders following any increase in the Commitments pursuant to this provision.

SECTION 2.08 Repayment of Loans; Evidence of Debt .

(a) The Borrower hereby unconditionally promises to pay to the Administrative Agent for the account of each Lender the then unpaid principal amount of each Loan of such Lender on the Revolving Maturity Date.

(b) Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the Indebtedness of the Borrower to such Lender resulting from each Loan made by such Lender, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder.

(c) The Administrative Agent shall maintain accounts in which it shall record (i) the amount of each Loan made hereunder and the Type thereof, (ii) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender hereunder and (iii) the amount of any sum received by the Administrative Agent hereunder for the account of the Lenders and each Lender’s share thereof.

(d) The entries made in the accounts maintained pursuant to Sections 2.08(b) or 2.08(c) shall be prima facie evidence of the existence and amounts of the obligations recorded therein; provided that the failure of any Lender or the Administrative Agent to maintain such accounts or

any error therein shall not in any manner affect the obligation of the Borrower to repay the Loans in accordance with the terms of this Agreement.

SECTION 2.09 [ Intentionally Left Blank ].

SECTION 2.10 Prepayment of Loans .

(a) The Borrower shall have the right at any time and from time to time to prepay any Borrowing in whole or in part without premium or penalty (except with respect to any amounts due under Section 2.15), subject to the requirements of this Section.

(b) In the event and on such occasion that the sum of the Revolving Exposures exceeds the total Commitments, the Borrower shall prepay Borrowings (or, if no such Borrowings are outstanding, deposit cash collateral in an account with the Administrative Agent pursuant to Section 2.04(j) ) in an aggregate amount equal to such excess.

(c) If, (i) at any time when Total Revolving Exposure is greater than zero, (ii) the Borrower and its Subsidiaries have a Consolidated Cash Balance in excess of $20,000,000 in the aggregate at any time (such excess being referred to herein as the “ Excess Amount ”), and (iii) the Total Leverage Ratio as of the most recently ended fiscal quarter for which financial statements have been delivered is greater than 1.00 to 1.00, then the Borrower shall immediately prepay the Borrowings in an amount equal to the Excess Amount.

(d) Each prepayment of Borrowings pursuant to Section 2.10(b) and Section 2.10(c) shall be applied, first , ratably to any ABR Borrowings then outstanding, and, second , ratably to any Eurodollar Borrowings then outstanding, and if more than one Eurodollar Borrowing is then outstanding, to each such Eurodollar Borrowing in order of priority beginning with the Eurodollar Borrowing with the least number of days remaining in the Interest Period applicable thereto and ending with the Eurodollar Borrowing with the most number of days remaining in the Interest Period applicable thereto.

(e) The Borrower shall notify the Administrative Agent by telephone (confirmed by telecopy or email) or email of any prepayment hereunder (a) in the case of a Eurodollar Borrowing, not later than 11:00 a.m., Houston, Texas time, three (3) Business Days before the date of prepayment and (b) in the case of an ABR Borrowing, not later than 11:00 a.m., Houston, Texas time, on the date of prepayment. Each such notice shall be irrevocable and shall specify the prepayment date, the principal amount of each Borrowing or portion thereof to be prepaid and, in the case of a mandatory prepayment, a reasonably detailed calculation of the amount of such prepayment; provided that, if a notice of optional prepayment is given in connection with a conditional notice of termination of the Commitments as contemplated by Section 2.07 , then such notice of prepayment may be revoked if such notice of termination is revoked in accordance with Section 2.07 . Promptly following receipt of any such notice, the Administrative Agent shall advise the Lenders of the contents thereof. Each partial prepayment of any Borrowing shall be in an amount that would be permitted in the case of an advance of a Borrowing of the same Type as

provided in Section 2.02 , except as necessary to apply fully the required amount of a mandatory prepayment.

(f) All Swap Agreements and agreements governing Banking Services between Borrower and any Lender (or any Affiliate of a Lender) are independent agreements governed by the written provisions of said Swap Agreements and said agreements governing Banking Services, which will remain in full force and effect, unaffected by any repayment, prepayment, acceleration, reduction, increase or change in the terms of the Obligations, except as otherwise expressly provided in said Swap Agreements and said agreements governing Banking Services, and any payoff statement relating to the Obligations shall not apply to said Swap Agreements or agreements governing Banking Services except as otherwise expressly provided in such payoff statement.

SECTION 2.11 Fees .

(a) The Borrower agrees to pay to the Administrative Agent for the account of each Lender a commitment fee, which shall accrue at the Applicable Commitment Fee on the average daily unused amount of the Commitment of such Lender during the period from and including the date hereof to but excluding the date on which such Commitment terminates. Accrued commitment fees shall be payable quarterly in arrears on the last Business Day of each March, June, September and December (commencing on the first such date to occur after the Effective Date) and on the date on which the Commitments terminate. All commitment fees shall be computed on the basis of a year of 360 days and shall be payable for the actual number of days elapsed (including the first day but excluding the last day). For purposes of computing such commitment fees, a Commitment of a Lender shall be deemed to be used to the extent of the outstanding Loans and LC Exposure of such Lender for purposes of calculating fees due under this Section 2.11(a) ).

(b) The Borrower agrees to pay (i) to the Administrative Agent for the account of each Lender a participation fee with respect to its participations in Letters of Credit, which shall accrue at the same Applicable Rate used to determine the interest rate applicable to Eurodollar Loans on the average daily amount of such Lender’s LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the period from and including the Effective Date to but excluding the later of the date on which such Lender’s Commitment terminates and the date on which such Lender ceases to have any LC Exposure (provided, however, that in no event shall the per annum fee for any single Letter of Credit be less than $750, payable quarterly in arrears in installments of $188 per quarter) and (ii) at any time or times that there shall be two or more Lenders, to the Issuing Bank a fronting fee, which shall accrue at the rate of 0.125% per annum on the average daily amount of the LC Exposure (excluding any portion thereof attributable to unreimbursed LC Disbursements) during the period from and including the Effective Date to but excluding the later of the date of termination of the Commitments and the date on which there ceases to be any LC Exposure, as well as the Issuing Bank’s standard fees with respect to the amendment, renewal or extension of any Letter of Credit or processing of drawings thereunder. Participation fees and fronting fees shall be payable quarterly in arrears on

the last Business Day of each March, June, September and December (commencing on the first such date to occur after the Effective Date); provided that all such fees shall be payable on the date on which the Commitments terminate and any such fees accruing after the date on which the Commitments terminate shall be payable on demand. Any other fees payable to the Issuing Bank pursuant to this Section 2.11(b) shall be payable within 10 Business Days after demand. All participation fees and fronting fees shall be computed on the basis of a year of 360 days and shall be payable for the actual number of days elapsed (including the first day but excluding the last day).

(c) The Borrower agrees to pay to the Administrative Agent, for its own account, fees payable in the amounts and at the times separately agreed upon between the Borrower and the Administrative Agent.

(d) All fees payable hereunder shall be paid on the dates due, in immediately available funds, to the Administrative Agent (or to the Issuing Bank, in the case of fees payable to it) for distribution, in the case of commitment fees and participation fees, to the Lenders entitled thereto. Fees paid shall not be refundable under any circumstances.

SECTION 2.12 Interest .

(a) Interest Rate Options .

(i) ABR Loans . The Loans comprising each ABR Borrowing shall bear interest at the Alternate Base Rate plus the Applicable Rate, but in no event to exceed the Highest Lawful Rate.

(ii) Eurodollar Loans . The Loans comprising each Eurodollar Borrowing shall bear interest at the Adjusted LIBO Rate for the Interest Period in effect for such Borrowing plus the Applicable Rate, but in no event to exceed the Highest Lawful Rate.

(b) Notwithstanding the foregoing, if any Event of Default has occurred which is continuing:

(i) any overdue amount shall bear interest at a rate per annum that is (x) in the case of overdue principal, the rate that would otherwise be applicable thereto plus 2%, not to exceed the Highest Lawful Rate, or (y) in the case of any other overdue amount, including overdue interest, to the extent permitted by applicable law, the rate applicable to ABR Borrowings plus 2%, not to exceed the Highest Lawful Rate (in each case, after as well as before judgment); and

(ii) at the election of the Required Lenders, the entire unpaid principal balance of the Loans shall bear interest at the rate that would otherwise be applicable thereto plus 2%, not to exceed the Highest Lawful Rate (in each case, after as well as before judgment).

(c) Accrued interest on each Loan shall be payable in arrears on each Interest Payment Date for such Loan and upon termination of the Commitments; provided that (i) interest accrued pursuant to Section 2.12(b) shall be payable on demand, (ii) in the event of any repayment or prepayment of any Loan (other than a prepayment of a Loan prior to the end of the Revolving Availability Period), accrued interest on the principal amount repaid or prepaid shall be payable on the date of such repayment or prepayment and (iii) in the event of a conversion of any Eurodollar Loan prior to the end of the current Interest Period therefor, accrued interest on such Loan shall be payable on the effective date of such conversion.

(d) All computations of interest for Loans bearing interest by reference to the Alternate Base Rate when the Alternate Base Rate is determined by the Prime Rate shall be made on the basis of a year of 365 or 366 days, as the case may be, and actual days elapsed. All other interest hereunder shall be computed on the basis of a year of 360 days. Interest shall be payable for the actual number of days elapsed (including the first day but excluding the last day). The applicable LIBO Rate shall be calculated by the Administrative Agent, and such calculation shall be presumed correct absent manifest error.

(e) Retroactive Adjustments of Applicable Margin . In the event that any financial statement or Compliance Certificate delivered pursuant to Section 5.01 is shown to be inaccurate (regardless of whether this Agreement or the Commitments are in effect when such inaccuracy is discovered), and such inaccuracy, if corrected, would have led to the application of a higher Applicable Rate (as in effect at the time of such inaccuracy) for any period (an “ Applicable Period ”) than the Applicable Rate applied for such Applicable Period, then (i) the Borrower shall immediately deliver to the Administrative Agent a corrected Compliance Certificate for such Applicable Period, (ii) the Applicable Rate shall be determined as if such higher Applicable Rate that would have applied were applicable for such Applicable Period (and in any event at the highest level set forth in the definition of “Applicable Rate” if the inaccuracy was the result of dishonesty, fraud or willful misconduct), and (iii) the Borrower shall immediately, without further action by the Administrative Agent, any Lender or the Issuing Bank, pay to the Administrative Agent for the account of the applicable Lenders and the Issuing Bank, the accrued additional interest and fees owing as a result of such increased Applicable Rate for such Applicable Period. This Section 2.12(e) shall not limit the rights of the Administrative Agent and Lenders with respect to the rate of interest as set forth in Section 2.12(b) or Article 7. The Borrower’s obligations under this Section 2.12(e) shall survive the termination of the Commitments and the repayment of all other Obligations hereunder.

SECTION 2.13 Alternate Rate of Interest . If prior to the commencement of any Interest Period for a Eurodollar Borrowing:

(a) the Administrative Agent determines (which determination shall be conclusive absent manifest error) that adequate and reasonable means do not exist for ascertaining the Adjusted LIBO Rate or the LIBO Rate for such Interest Period; or

(b) the Administrative Agent is advised by the Required Lenders that the Adjusted LIBO Rate or LIBO Rate, as applicable, for such Interest Period will not adequately and fairly reflect the cost to such Lenders of making or maintaining their Loans included in such Borrowing for such Interest Period;

(c) then the Administrative Agent shall give notice thereof to the Borrower and the Lenders by telephone, telecopy or other electronic transmission as promptly as practicable thereafter and, until the Administrative Agent notifies the Borrower and the Lenders that the circumstances giving rise to such notice no longer exist, (i) any Interest Election Request that requests the conversion of any Borrowing to, or continuation of any Borrowing as, a Eurodollar Borrowing shall be ineffective (and such Borrowing shall be automatically converted into ABR Loans on the last day of the applicable Interest Period), and (ii) if any Borrowing Request requests a Eurodollar Borrowing, such Borrowing shall be made as an ABR Borrowing; and

(d) notwithstanding anything to the contrary in clauses (a), (b) and (c) above, if the Administrative Agent has made the determination (such determination to be conclusive absent manifest error) or the Required Lenders notify the Administrative Agent that the Required Lenders have made the determination, that (A) the circumstances described in clause (a) and (b) have arisen and that such circumstances are unlikely to be temporary, (B) any applicable interest rate specified herein is no longer a widely recognized benchmark rate for newly originated loans in the U.S. syndicated loan market in the applicable currency or (C) the applicable supervisor or administrator (if any) of any applicable interest rate specified herein or any Governmental Authority having, or purporting to have, jurisdiction over the Administrative Agent has made a public statement identifying a specific date after which any applicable interest rate specified herein shall no longer be used for determining interest rates for loans in the U.S. syndicated loan market in the applicable currency, then the Administrative Agent may, to the extent practicable (subject to the consent of the Borrower and as determined by the Administrative Agent to be generally in accordance with similar situations in other transactions in which it is serving as administrative agent or otherwise consistent with market practice generally), establish a replacement interest rate (the “ Replacement Rate ”), in which case, the Replacement Rate shall, subject to the next two sentences, replace such applicable interest rate for all purposes under the Loan Documents unless and until (1) an event described in clause (a) or (b) occurs with respect to the Replacement Rate or (2) the Administrative Agent (or the Required Lenders through the Administrative Agent) notifies the Borrower that the Replacement Rate does not adequately and fairly reflect the cost to the Lenders of funding the Borrowings bearing interest at the Replacement Rate. In connection with the establishment and application of the Replacement Rate, this Agreement and the other Loan Documents shall be amended solely with the consent of the Administrative Agent and the Borrower, as may be necessary or appropriate, in the opinion of the Administrative Agent, to effect the provisions of this clause (d). Notwithstanding anything to the contrary in this Agreement or the other Loan Documents (including, without limitation, Section 9.02), such amendment shall become effective without any further action or consent of any other party to this Agreement so long as the Administrative Agent shall not have received, within five Business Days of the delivery of such amendment to the Lenders, written notices from such Lenders that in the aggregate constitute Required Lenders, with each such notice stating that such Lender objects to such amendment. To

the extent the Replacement Rate is approved by the Administrative Agent and the Borrower in connection with this clause (d), the Replacement Rate shall be applied in a manner consistent with market practice; provided that, in each case, to the extent such market practice is not administratively feasible for the Administrative Agent, such Replacement Rate shall be applied as otherwise reasonably determined by the Administrative Agent in consultation with the Borrower (it being understood that any such modification by the Administrative Agent shall not require the consent of, or consultation with, any of the Lenders). Notwithstanding anything to the contrary, if no Replacement Rate has been determined and the circumstances under clauses (A), (B) or (C) above exist, until a Replacement Rate shall have been determined in accordance with the terms hereof, (x) the Borrower may revoke any pending Borrowing Request, (y) the Borrower may revoke any notice that requests the conversion of any Loan to, or continuation of any Loan as, a Eurodollar Loan (to the extent of the affected Eurodollar Loan or Interest Periods) and (z) failing any revocation by the Borrower pursuant to the immediately preceding clauses (x) or (y), if any Borrowing Request requests a Eurodollar Loan, or conversion or continuation of a Eurodollar Loan, such Loan shall be made as an ABR Loan in the amount specified in such Borrowing Request.

SECTION 2.14 Increased Costs .

(a) Increased Costs Generally . If any Change in Law shall:

(i) impose, modify or deem applicable any reserve, special deposit, compulsory loan, insurance charge or similar requirement against assets of, deposits with or for the account of, or advances, loans or other credit extended or participated in by, any Lender (except any reserve requirement reflected in the Adjusted LIBO Rate) or any Issuing Bank;

(ii) subject any Recipient to any Taxes (other than (A) Indemnified Taxes, (B) Taxes described in clauses (b) through (d) of the definition of Excluded Taxes and (C) Connection Income Taxes) on its loans, loan principal, letters of credit, commitments, or other obligations, or its deposits, reserves, other liabilities or capital attributable thereto; or

(iii) impose on any Lender or any Issuing Bank or the London interbank market any other condition, cost or expense (other than Taxes) affecting this Agreement or Loans made by such Lender or any Letter of Credit or participation therein;

and the result of any of the foregoing shall be to increase the cost to such Lender or such other Credit Party of making, converting to, continuing or maintaining any Loan or of maintaining its obligation to make any such Loan, or to increase the cost to such Lender, such Issuing Bank or other Credit Party of participating in, issuing or maintaining any Letter of Credit (or of maintaining its obligation to participate in or to issue any Letter of Credit) or to reduce the amount of any sum received or receivable by such Lender or such other Credit Party (whether of principal, interest or otherwise), then the Borrower will pay to such Lender or such other Credit Party such additional

amount or amounts as will compensate such Lender or such other Credit Party for such additional costs incurred or reduction suffered.

(b) Capital Requirements . If any Lender or Issuing Bank determines that any Change in Law regarding capital or liquidity requirements has or would have the effect of reducing the rate of return on such Lender’s or Issuing Bank’s capital or on the capital of such Lender’s or Issuing Bank’s holding company, if any, as a consequence of this Agreement, the Commitments of such Lender or the Loans made by, or participations in Letters of Credit held by, such Lender, or the Letters of Credit issued by any Issuing Bank, to a level below that which such Lender or Issuing Bank or such Lender’s or Issuing Bank’s holding company could have achieved but for such Change in Law (taking into consideration such Lender’s or Issuing Bank’s policies and the policies of such Lender’s or Issuing Bank’s holding company with respect to capital adequacy or liquidity), then from time to time the Borrower will pay to such Lender or Issuing Bank, as the case may be, such additional amount or amounts as will compensate such Lender or Issuing Bank or such Lender’s or Issuing Bank’s holding company for any such reduction suffered.

(c) Certificates for Reimbursement . A certificate of a Lender or Issuing Bank setting forth the amount or amounts necessary to compensate such Lender or Issuing Bank or its holding company, as the case may be, as specified in Section 2.14(a) or Section 2.14(b) shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Lender or Issuing Bank, as the case may be, the amount shown as due on any such certificate within 10 days after receipt thereof.

(d) Effect of Failure or Delay in Requesting Compensation . Failure or delay on the part of any Lender or Issuing Bank to demand compensation pursuant to this Section 2.14 shall not constitute a waiver of such Lender’s or Issuing Bank’s right to demand such compensation; provided that the Borrower shall not be required to compensate a Lender or Issuing Bank pursuant to this Section 2.14 for any increased costs or reductions incurred more than 180 days prior to the date that such Lender or Issuing Bank, as the case may be, notifies the Borrower of the Change in Law giving rise to such increased costs or reductions and of such Lender’s or Issuing Bank’s intention to claim compensation therefor; provided further that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the 180 day period referred to above shall be extended to include the period of retroactive effect thereof.

SECTION 2.15 Break Funding Payments . In the event of (a) the payment of any principal of any Eurodollar Loan other than on the last day of an Interest Period applicable thereto (including as a result of an Event of Default), (b) the conversion of any Eurodollar Loan into an ABR Loan other than on the last day of the Interest Period applicable thereto, (c) the failure to borrow, convert, continue or prepay any Eurodollar Loan on the date specified in any notice delivered pursuant hereto, or (d) the assignment of any Eurodollar Loan other than on the last day of the Interest Period applicable thereto as a result of a request by the Borrower pursuant to Section 2.06 then, in any such event, the Borrower shall compensate each Lender for the loss, cost and expense attributable to such event. In the case of a Eurodollar Loan, such loss, cost or expense to any Lender shall be deemed to include an amount determined by such Lender to be the excess, if any,

of (i) the amount of interest which would have accrued on the principal amount of such Loan had such event not occurred, at the Adjusted LIBO Rate that would have been applicable to such Loan, for the period from the date of such event to the last day of the then current Interest Period therefor (or, in the case of a failure to borrow, convert or continue, for the period that would have been the Interest Period for such Loan), over (ii) the amount of interest which would accrue on such principal amount for such period at the interest rate which such Lender would bid were it to bid, at the commencement of such period, for dollar deposits of a comparable amount and period from other banks in the eurodollar market.

A certificate of any Lender setting forth any amount or amounts that such Lender is entitled to receive pursuant to this Section 2.15 and demonstrating, in reasonable detail, the computation of such amount or amounts shall be delivered to the Borrower and shall be conclusive absent manifest error. The Borrower shall pay such Lender the amount shown as due on any such certificate within 10 days after receipt thereof.

SECTION 2.16 Taxes .

(a) Any and all payments by or on account of any obligation of any Loan Party under any Loan Document shall be made without deduction or withholding for any Taxes, except as required by applicable law. If any applicable law (as determined in the good faith discretion of an applicable withholding agent) requires the deduction or withholding of any Tax from any such payment by a withholding agent, then the applicable withholding agent shall be entitled to make such deduction or withholding and shall timely pay the full amount deducted or withheld to the relevant Governmental Authority in accordance with applicable law and, if such Tax is an Indemnified Tax, then the sum payable by the applicable Loan Party shall be increased as necessary so that after such deduction or withholding has been made (including such deductions and withholdings applicable to additional sums payable under this Section) the applicable Recipient receives an amount equal to the sum it would have received had no such deduction or withholding been made.

(b) The Loan Parties shall timely pay to the relevant Governmental Authority in accordance with applicable law, or at the option of the Administrative Agent timely reimburse it for, Other Taxes.

(c) As soon as practicable after any payment of Taxes by any Loan Party to a Governmental Authority pursuant to this Section, such Loan Party shall deliver to the Administrative Agent the original or a certified copy of a receipt issued by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment reasonably satisfactory to the Administrative Agent.

(d) The Borrower shall indemnify each Recipient, within 10 days after demand therefor, for the full amount of any Indemnified Taxes (including Indemnified Taxes imposed or asserted on or attributable to amounts payable under this Section) payable or paid by such Recipient or required to be withheld or deducted from a payment to such Recipient and any

reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to the Borrower by a Lender (with a copy to the Administrative Agent), or by the Administrative Agent on its own behalf or on behalf of a Lender, shall be conclusive absent manifest error.

(e) Each Lender shall severally indemnify the Administrative Agent, within 10 days after demand therefor, for (i) any Indemnified Taxes attributable to such Lender (but only to the extent that the Borrower has not already indemnified the Administrative Agent for such Indemnified Taxes and without limiting the obligation of the Borrower to do so), (ii) any Taxes attributable to such Lender’s failure to comply with the provisions of Section 9.04(c) relating to the maintenance of a Participant Register and (iii) any Excluded Taxes attributable to such Lender, in each case, that are payable or paid by the Administrative Agent in connection with any Loan Document, and any reasonable expenses arising therefrom or with respect thereto, whether or not such Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to any Lender by the Administrative Agent shall be conclusive absent manifest error. Each Lender hereby authorizes the Administrative Agent to set off and apply any and all amounts at any time owing to such Lender under any Loan Document or otherwise payable by the Administrative Agent to such Lender from any other source against any amount due to the Administrative Agent under this Section 2.16(e) .

(f) (i) Any Lender that is entitled to an exemption from or reduction of withholding Tax with respect to payments made under any Loan Document shall deliver to the Borrower and the Administrative Agent, at the time or times reasonably requested by the Borrower or the Administrative Agent, such properly completed and executed documentation as reasonably requested by the Borrower or the Administrative Agent as will permit such payments to be made without withholding or at a reduced rate of withholding. In addition, any Lender, if reasonably requested by the Borrower or the Administrative Agent, shall deliver such other documentation prescribed by applicable law or reasonably requested by the Borrower or the Administrative Agent as will enable the Borrower or the Administrative Agent to determine whether or not such Lender is subject to backup withholding or information reporting requirements. Notwithstanding anything to the contrary in the preceding two sentences, the completion, execution and submission of such documentation (other than such documentation set forth in Sections 2.16(f)(ii)(A) , (ii)(B) , (ii)(C) and (ii)(D) below) shall not be required if in the relevant Lender’s reasonable judgment such completion, execution or submission would subject such Lender to any material unreimbursed cost or expense or would materially prejudice the legal or commercial position of such Lender.

(ii) Without limiting the generality of the foregoing, in the event that the Borrower is a U.S. Person:

(A) any Lender that is a U.S. Person shall deliver to the Borrower and the Administrative Agent on or prior to the date on which such Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), executed copies of IRS Form

(C) any Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower and the Administrative Agent (in such number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower or the Administrative Agent), executed originals of any other form prescribed by applicable law as a basis for claiming exemption from or a reduction in U.S. federal withholding Tax, duly completed, together with such supplementary documentation as may be prescribed by applicable law to permit the Borrower or the Administrative Agent to determine the withholding or deduction required to be made; and

(D) if a payment made to a Lender under any Loan Document would be subject to U.S. federal withholding Tax imposed by FATCA if such Lender were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b) of the Code, as applicable), such Lender shall deliver to the Borrower and the Administrative Agent at the time or times prescribed by law and at such time or times reasonably requested by the Borrower or the Administrative Agent such documentation prescribed by applicable law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably requested by the Borrower or the Administrative Agent as may be necessary for the Borrower and the Administrative Agent to comply with their obligations under FATCA and to determine that such Lender has complied with such Lender’s obligations under FATCA or to determine the amount to deduct and withhold from such payment. Solely for purposes of this clause (D) , “FATCA” shall include any amendments made to FATCA after the date of this Agreement.

Each Lender agrees that if any form or certification it previously delivered expires or becomes obsolete or inaccurate in any respect, it shall update such form or certification or promptly notify the Borrower and the Administrative Agent in writing of its legal inability to do so.

indemnifying party an amount equal to such refund (but only to the extent of indemnity payments made under this Section with respect to the Taxes giving rise to such refund), net of all out-of-pocket expenses (including Taxes) of such indemnified party and without interest (other than any interest paid by the relevant Governmental Authority with respect to such refund). Such indemnifying party, upon the request of such indemnified party, shall repay to such indemnified party the amount paid over pursuant to this Section 2.16(g) (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) in the event that such indemnified party is required to repay such refund to such Governmental Authority. Notwithstanding anything to the contrary in this Section 2.16(g) , in no event will the indemnified party be required to pay any amount to an indemnifying party pursuant to this Section 2.16(g) the payment of which would place the indemnified party in a less favorable net after-Tax position than the indemnified party would have been in if the Tax subject to indemnification and giving rise to such refund had not been deducted, withheld or otherwise imposed and the indemnification payments or additional amounts with respect to such Tax had never been paid. This paragraph shall not be construed to require any indemnified party to make available its Tax returns (or any other information relating to its Taxes that it deems confidential) to the indemnifying party or any other Person.

SECTION 2.17 Payments Generally; Pro Rata Treatment; Sharing of Set-offs .

(a) The Borrower shall make each payment required to be made by it hereunder or under any other Loan Document (whether of principal, interest, fees or reimbursement of LC Disbursements, or of amounts payable under Section 2.14 , Section 2.15 , Section 2.16 , or otherwise) by the time expressly required hereunder or under such other Loan Document for such payment (or, if no such time is expressly required, prior to 2:00 p.m., Houston, Texas time), on the date when due, in immediately available funds, without set off, deduction or counterclaim. Any amounts received after such time on any date may, in the discretion of the Administrative Agent, be deemed to have been received on the next succeeding Business Day for purposes of calculating interest thereon. All such payments shall be made to the Administrative Agent at its offices specified in Section 9.01(a) , except payments to be made directly to the Issuing Bank as expressly provided herein and except that payments pursuant to Sections 2.14 , 2.15 , 2.16 and 9.03 shall be made directly to the Persons entitled thereto and payments pursuant to other Loan Documents shall be made to the Persons specified therein. The Administrative Agent shall distribute any such payments received by it for the account of any other Person to the appropriate recipient promptly following receipt thereof. If any payment under any Loan Document shall be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day,

and, in the case of any payment accruing interest, interest thereon shall be payable for the period of such extension. All payments under each Loan Document shall be made in dollars.

(b) If at any time insufficient funds are received by and available to the Administrative Agent to pay fully all amounts of principal, unreimbursed LC Disbursements, interest and fees and other Obligations then due, such funds shall be applied (i) first, towards payment of interest and fees then due hereunder, ratably among the parties entitled thereto in accordance with the amounts of interest and fees then due to such parties, and (ii) second, towards payment of principal and unreimbursed LC Disbursements and other Obligations then due, ratably among the parties entitled thereto in accordance with the amounts of principal and unreimbursed LC Disbursements and other Obligations then due to such parties.

(c) If any Lender shall, by exercising any right of set off or counterclaim or otherwise, obtain payment in respect of any principal of or interest on any of its Loans or participations in LC Disbursements, resulting in such Lender receiving payment of a greater proportion of the aggregate amount of its Loans and participations in LC Disbursements and accrued interest thereon than the proportion received by any other Lender, then the Lender receiving such greater proportion shall purchase (for cash at face value) participations in the Loans and participations in LC Disbursements of other Lenders to the extent necessary so that the benefit of all such payments shall be shared by the Lenders ratably in accordance with the aggregate amount of principal of and accrued interest on their respective Loans and participations in LC Disbursements; provided that (i) if any such participations are purchased and all or any portion of the payment giving rise thereto is recovered, such participations shall be rescinded and the purchase price restored to the extent of such recovery, without interest, and (ii) the provisions of this Section 2.17(c) shall not be construed to apply to any payment made by the Borrower pursuant to and in accordance with the express terms of this Agreement or any payment obtained by a Lender as consideration for the assignment of or sale of a participation in any of its Loans or participations in LC Disbursements to any assignee or participant, other than to the Borrower or any other Loan Party or Affiliate thereof (as to which the provisions of this Section 2.17(c) shall apply). Each Lender agrees that it will not exercise any right of set-off or counterclaim or otherwise obtain payment in respect of any Obligation owed to it other than principal of and interest accruing on the Loans and participations in the LC Disbursements, unless all of the outstanding principal of and accrued interest on the Loans and LC Disbursements have been paid in full. The Borrower consents to the foregoing and agrees, to the extent it may effectively do so under applicable law, that any Lender acquiring a participation pursuant to the foregoing arrangements may exercise against the Borrower rights of set-off and counterclaim with respect to such participation as fully as if such Lender were a direct creditor of the Borrower in the amount of such participation.

(d) Unless the Administrative Agent shall have received notice from the Borrower prior to the date on which any payment is due to the Administrative Agent for the account of the Lenders or the Issuing Bank hereunder that the Borrower will not make such payment, the Administrative Agent may assume that the Borrower has made such payment on such date in accordance herewith and may, in reliance upon such assumption, distribute to the Lenders or the Issuing Bank, as the case may be, the amount due. If the Borrower has not in fact made such payment when due, then

each of the Lenders or the Issuing Bank, as the case may be, severally agrees to repay to the Administrative Agent forthwith on demand the amount so distributed to such Lender or Issuing Bank with interest thereon, for each day from and including the date such amount is distributed to it to but excluding the date of payment to the Administrative Agent, at the greater of the Federal Funds Effective Rate and a rate determined by the Administrative Agent in accordance with banking industry rules on interbank compensation.

(e) If any Lender shall fail to make any payment required to be made by it pursuant to this Agreement, then the Administrative Agent may, in its discretion (and notwithstanding any contrary provision hereof), (i) apply any amounts thereafter received by the Administrative Agent for the account of such Lender for the benefit of the Administrative Agent to satisfy such Lender’s obligations to it under this Agreement until all such unsatisfied obligations are fully paid, and/or (ii) hold any such amounts in a segregated account as cash collateral for, and application to, any future funding obligations of such Lender under this Agreement, in the case of each of clauses (i) and (ii) above, in any order as determined by the Administrative Agent in its discretion.

(f) Notwithstanding the foregoing, amounts received from any Loan Party that is not a Qualified ECP Loan Party shall not be applied to any Excluded Swap Obligation of such Loan Party.

SECTION 2.18 Mitigation Obligations; Replacement of Lenders .

(a) If the Borrower is required to pay any Indemnified Taxes or additional amounts to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.16 , then such Lender shall use reasonable efforts to designate a different lending office for funding or booking its Loans hereunder or to assign its rights and obligations hereunder to another of its offices, branches or Affiliates, if, in the judgment of such Lender, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 2.16 in the future and (ii) would not subject such Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Lender. The Borrower hereby agrees to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment.

(b) If the Borrower is required to pay any Indemnified Taxes or additional amounts to any Lender or any Governmental Authority for the account of any Lender pursuant to Section 2.16 , if the Borrower is required to make any payment pursuant to Section 2.14 , or if any Lender becomes a Defaulting Lender, then the Borrower may, at its sole expense and effort, upon notice to such Lender and the Administrative Agent, require such Lender to assign and delegate, without recourse (in accordance with and subject to the restrictions contained in Section 9.04 ), all its interests, rights (other than its existing rights to payments pursuant to Section 2.16 ) and obligations under this Agreement to an assignee that shall assume such obligations (which assignee may be another Lender, if a Lender accepts such assignment); provided that (i) the Borrower shall have received the prior written consent of the Administrative Agent (and, if a Commitment is being assigned, the Issuing Bank), which consent shall not unreasonably be withheld, (ii) such assignor Lender shall have received payment of an amount equal to the outstanding principal of its Loans

and participations in LC Disbursements, accrued interest thereon, accrued fees and all other amounts payable to it hereunder (including any amounts under Section 2.15) , from the assignee (to the extent of such outstanding principal and accrued interest and fees) or the Borrower (in the case of all other amounts) and (iii) in the case of any such assignment resulting from payments required to be made pursuant to Section 2.16 , such assignment will result in a reduction in such compensation or payments. A Lender shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Lender, the circumstances entitling the Borrower to require such assignment and delegation cease to apply.

SECTION 2.19 [Intentionally Left Blank] .

SECTION 2.20 Defaulting Lender . Notwithstanding any provision of this Agreement to the contrary, if any Lender becomes a Defaulting Lender, then the following provisions shall apply for so long as such Lender is a Defaulting Lender:

(a) fees shall cease to accrue on the unfunded portion of any Commitment of such Defaulting Lender pursuant to this Agreement;

(b) the Commitments and Revolving Exposure of such Defaulting Lender shall not be included in determining whether the Required Lenders have taken or may take any action hereunder (including any consent to any amendment, waiver or other modification pursuant to Section 9.02 ); provided, that in the case of an amendment, waiver or other modification requiring the consent of all Lenders or of each Lender affected thereby, the Defaulting Lender’s consent shall be only be required with respect to (i) a proposed increase or extension of such Defaulting Lender’s Commitments and (ii) a proposed reduction or excuse, or a proposed postponement of the scheduled date of payment, of the principal amount of, or interest or fees payable on, any Loans or LC Disbursements as to any such Defaulting Lender;

(i) all or any part of the LC Exposure of such Defaulting Lender shall be reallocated among the non-Defaulting Lenders in accordance with their respective Applicable Percentages but only (x) to the extent that such reallocation does not, as to any non-Defaulting Lender, cause such non-Defaulting Lender’s Revolving Exposure to exceed its Commitment and (y) if the conditions set forth in Section 4.03 are satisfied at that time;

(ii) if the reallocation described in clause (i) above cannot, or can only partially, be effected, the Borrower shall within one (1) Business Day following notice by the Administrative Agent, cash collateralize for the benefit of the Issuing Bank only the Borrower’s obligations corresponding to such Defaulting Lender’s LC Exposure (after giving effect to any partial reallocation pursuant to clause (i) above) in accordance with the procedures set forth in Section 2.04(j) for so long as such LC Exposure is outstanding;

(iii) if the Borrower cash collateralizes any portion of such Defaulting Lender’s LC Exposure pursuant to this Section 2.20(c) , the Borrower shall not be required to pay any fees to such Defaulting Lender pursuant to Section 2.11 with respect to such Defaulting Lender’s LC Exposure during the period such Defaulting Lender’s LC Exposure is cash collateralized;

(iv) if the LC Exposure of the non-Defaulting Lenders is reallocated pursuant to this Section 2.20(c) , then the fees payable to the Lenders pursuant to Section 2.11 shall be adjusted in accordance with such non-Defaulting Lenders’ Applicable Percentages; and

(v) if all or any portion of such Defaulting Lender’s LC Exposure is neither cash collateralized nor reallocated pursuant to this Section 2.20(c) , then, without prejudice to any rights or remedies of the Issuing Bank or any Lender hereunder, all fees that otherwise would have been payable to such Defaulting Lender (solely with respect to the portion of such Defaulting Lender’s Commitments that were utilized by such LC Exposure and any applicable letter of credit fees) with respect to such Defaulting Lender’s LC Exposure shall be payable to the Issuing Bank until and to the extent that such LC Exposure is cash collateralized and/or reallocated; and

(d) so long as any Lender is a Defaulting Lender, the Issuing Bank shall not be required to issue, amend or increase any Letter of Credit, unless it is satisfied that the related exposure and each Defaulting Lender’s then outstanding LC Exposure will be 100% covered by the Commitments of the non-Defaulting Lenders and/or cash collateral will be provided by the Borrower in accordance with Section 2.20(c) , and LC Exposure related to any newly issued or increased Letter of Credit shall be allocated among non-Defaulting Lenders in a manner consistent with Section 2.20(c)(i) (and Defaulting Lenders shall not participate therein).

If (i) a Bankruptcy Event with respect to any Lender Parent shall occur following the date hereof and for so long as such event shall continue or (ii) the Issuing Bank has a good faith belief that any Lender has defaulted in fulfilling its obligations under one or more other agreements in which such Lender commits to extend credit, the Issuing Bank shall not be required to issue, amend or increase any Letter of Credit, unless the Issuing Bank shall have entered into arrangements with the Borrower or such Lender, satisfactory to the Issuing Bank to defease any risk to it in respect of such Lender hereunder.

In the event that the Administrative Agent, the Borrower and the Issuing Bank each agrees that a Defaulting Lender has adequately remedied all matters that caused such Lender to be a Defaulting Lender, then the LC Exposure of the Lenders shall be readjusted to reflect the inclusion of such Lender’s Commitment and on such date such Lender shall purchase at par such of the Loans of the other Lenders as the Administrative Agent shall determine may be necessary in order for such Lender to hold such Loans in accordance with its Applicable Percentage.

The fees payable by the Borrower to a successor Administrative Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After the Administrative Agent’s resignation hereunder, the provisions of this Article and Section 9.03 shall continue in effect for the benefit of such retiring Administrative Agent, its sub agents and their respective Related Parties in respect of any actions taken or omitted to be taken by any of them while it was acting as Administrative Agent.

Each Lender acknowledges and agrees that the extensions of credit made hereunder are commercial loans and letters of credit and not investments in a business enterprise or securities. Each Lender further represents that it is engaged in making, acquiring or holding commercial loans in the ordinary course of its business and has, independently and without reliance upon the Administrative Agent or any other Lender and based on such documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement as a Lender, and to make, acquire or hold Loans hereunder. Each Lender shall, independently and without reliance upon the Administrative Agent or any other Lender and based on such documents and information (which may contain material, non-public information within the meaning of the United States securities laws concerning the Borrower and its Affiliates) as it shall from time to time deem appropriate, continue to make its own decisions in taking or not taking action under or based upon this Agreement, any related agreement or any document furnished hereunder or thereunder and in deciding whether or to the extent to which it will continue as a Lender or assign or otherwise transfer its rights, interests and obligations hereunder.

(a) No failure or delay by the Administrative Agent, the Issuing Bank or any Lender in exercising any right or power hereunder or under any other Loan Document shall operate as a waiver thereof, nor shall any single or partial exercise of any such right or power, or any abandonment or discontinuance of steps to enforce such a right or power, preclude any other or further exercise thereof or the exercise of any other right or power. The rights and remedies of the Administrative Agent, the Issuing Bank and the Lenders hereunder and under the other Loan Documents are cumulative and are not exclusive of any rights or remedies that they would otherwise have. No waiver of any provision of any Loan Document or consent to any departure by any Loan Party therefrom shall in any event be effective unless the same shall be permitted by Section 9.02(b) , and then such waiver or consent shall be effective only in the specific instance and for the purpose for which given.

(b) Subject to Section 9.02(c) below, neither this Agreement nor any other Loan Document nor any provision hereof or thereof may be waived, amended or modified except, in the case of this Agreement, pursuant to an agreement or agreements in writing entered into by the Borrower and the Required Lenders or, in the case of any other Loan Document, pursuant to an agreement or agreements in writing entered into by the Administrative Agent and the Obligor or Obligors that are parties thereto, in each case with the consent of the Required Lenders; provided that no such agreement shall (i) increase the Commitment of any Lender without the written consent of such Lender, (ii) reduce the principal amount of any Loan or LC Disbursement or reduce the rate of interest thereon, or reduce any fees payable hereunder, without the written consent of each Lender affected thereby (it being understood that the Administrative Agent and the Borrower may, without the consent of any Lender, enter into amendments or modifications to this Agreement or any of the other Loan Documents or enter into additional Loan Documents as the Administrative Agent reasonably deems appropriate in order to implement any Replacement Rate or otherwise effectuate the terms of Section 2.13(d) in accordance with the terms of such Section),

(iii) postpone the scheduled date of payment (including any mandatory prepayment) of the principal amount of any Loan or LC Disbursement, or any interest thereon, or any fees payable hereunder, or reduce the amount of, waive or excuse any such payment, or postpone the scheduled date of expiration of any Commitment, without the written consent of each Lender affected thereby, (iv) change Section 2.17(b) or (c) in a manner that would alter the pro rata sharing of payments required thereby, without the written consent of each Lender, (v) change any of the provisions of this Section or the definition of “Required Lenders” or any other provision of any Loan Document specifying the number or percentage of Lenders required to waive, amend or modify any rights thereunder or make any determination or grant any consent thereunder, without the written consent of each Lender, (vi) release all or substantially all of the Guarantors from liability under the Guaranty or limit the liability of all or substantially all of the Guarantors in respect of the Guaranty, without the written consent of each Lender, or (vii) release all or substantially all of the Collateral from the Liens of the Security Documents, without the written consent of each Lender; provided further that (A) any change to Section 2.20 shall require the written consent of each of the Administrative Agent and the Issuing Bank, (B) no agreement shall amend, modify or otherwise affect any of the rights or duties of the Administrative Agent or the Issuing Bank without the prior written consent of the Administrative Agent or the Issuing Bank, as the case may be, (C) no such agreement shall amend or modify the provisions of Section 2.05 or any letter of credit application and any bilateral agreement between the Borrower and the Issuing Bank regarding the respective rights and obligations between the Borrower and the Issuing Bank in connection with the issuance of Letters of Credit without the prior written consent of the Administrative Agent and the Issuing Bank, respectively, and (D) any waiver, amendment or modification of this Agreement that by its terms affects the rights or duties under this Agreement of the Lenders may be effected by an agreement or agreements in writing entered into by the Borrower and requisite percentage in interest of the Lenders.

(c) If the Administrative Agent and the Borrower acting together identify any ambiguity, omission, mistake, typographical error or other defect in any provision of this Agreement or any other Loan Document, then the Administrative Agent and the Borrower shall be permitted to amend, modify or supplement such provision to cure such ambiguity, omission, mistake, typographical error or other defect, and such amendment shall become effective without any further action or consent of any other party to this Agreement.

SECTION 9.03 Expenses; Indemnity; Damage Waiver .

(a) The Borrower shall pay (i) all reasonable out of pocket expenses incurred by the Administrative Agent and its Affiliates, including the reasonable fees, charges and disbursements of one law firm for the Administrative Agent, in connection with the syndication of the credit facilities provided for herein, the preparation and administration of the Loan Documents or any amendments, modifications or waivers of the provisions thereof (whether or not the transactions contemplated hereby or thereby shall be consummated), (ii) all reasonable out of-pocket expenses incurred by the Issuing Bank in connection with the issuance, amendment, renewal or extension of any Letter of Credit or any demand for payment thereunder and (iii) all out-of-pocket expenses incurred by the Administrative Agent, the Issuing Bank or any Lender, including the fees, charges

BREACH OF THIS AGREEMENT IN BAD FAITH BY, SUCH INDEMNITEE, BUT THE AVAILABILITY OF SUCH INDEMNITY SHALL NOT BE AFFECTED IN ALL CASES, WHETHER OR NOT CAUSED BY OR ARISING, IN WHOLE OR IN PART, OUT OF THE COMPARATIVE, CONTRIBUTORY OR SOLE NEGLIGENCE OF ANY INDEMNITEE . THIS SECTION 9.03(B) SHALL NOT APPLY WITH RESPECT TO TAXES OTHER THAN ANY TAXES THAT REPRESENT LOSSES, CLAIMS OR DAMAGES ARISING FROM ANY NON-TAX CLAIM.

(c) To the extent that the Borrower fails to pay any amount required to be paid by it to the Administrative Agent or the Issuing Bank under Sections 9.03(a) or 9.03(b) , each Lender severally agrees to pay to the Administrative Agent or the Issuing Bank, as the case may be, such Lender’s pro rata share (determined as of the time that the applicable unreimbursed expense or indemnity payment is sought) of such unpaid amount; provided that the unreimbursed expense or indemnified loss, claim, damage, liability or related expense, as the case may be, was incurred by or asserted against the Administrative Agent or the Issuing Bank in its capacity as such. For purposes hereof, a Lender’s “pro rata share” shall be determined based upon (without duplication) its share of the sum of the total Revolving Exposures and unused Commitments at the time.

(d) To the extent permitted by applicable law, no party hereto shall assert, and each such party hereby waives, any claim against any other party hereto, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement, any other Loan Document or any agreement or instrument contemplated hereby or thereby, the Transactions, any Loan or Letter of Credit or the use of the proceeds thereof; provided that, nothing in this clause (d) shall relieve the Borrower of any obligation it may have to indemnify an Indemnitee against special, indirect, consequential or punitive damages asserted against such Indemnitee by a third party.

(e) All amounts due under this Section shall be payable not later than three (3) Business Days after written demand therefor.

SECTION 9.04 Successors and Assigns .

(a) The provisions of this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns permitted hereby (including any Affiliate of the Issuing Bank that issues any Letter of Credit), except that (i) the Borrower may not assign or otherwise transfer any of its rights or obligations hereunder without the prior written consent of each Lender (and any attempted assignment or transfer by the Borrower without such consent shall be null and void) and (ii) no Lender may assign or otherwise transfer its rights or obligations hereunder except in accordance with this Section. Nothing in this Agreement, expressed or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns permitted hereby (including any Affiliate of the Issuing Bank that issues any Letter of Credit), Participants (to the extent provided in Section 9.04(c) ) and, to the extent expressly contemplated hereby, the Related Parties of each of the Administrative

Agent, the Issuing Bank and the Lenders) any legal or equitable right, remedy or claim under or by reason of this Agreement.

(b) (i) Subject to the conditions set forth in paragraph (b)(ii) below, any Lender may assign to one or more Persons (other than an Ineligible Institution) all or a portion of its rights and obligations under this Agreement (including all or a portion of its Commitment, participations in Letters of Credit and the Loans at the time owing to it) with the prior written consent (such consent not to be unreasonably withheld) of:

(A) the Borrower, provided that no consent of the Borrower shall be required for an assignment to a Lender, an Affiliate of a Lender, an Approved Fund or, if an Event of Default has occurred and is continuing, any other assignee, and provided further that the Borrower shall be deemed to have consented to any such assignment unless it shall object thereto by written notice to the Administrative Agent within ten (10) Business Days after having received notice thereof; and

(B) the Administrative Agent, provided that no consent of the Administrative Agent shall be required for an assignment of any Commitment to an assignee that is a Lender (other than a Defaulting Lender) with a Commitment immediately prior to giving effect to such assignment; and

(ii) Assignments shall be subject to the following additional conditions:

(A) except in the case of an assignment to a Lender or an Affiliate of a Lender or an assignment of the entire remaining amount of the assigning Lender’s Commitment or Loans, the amount of the Commitment or Loans of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Assumption with respect to such assignment is delivered to the Administrative Agent) shall not be less than $500,000 in respect of a Commitment, and shall not result in the assigning Lender holding a Commitment of less than $2,500,000, unless each of the Borrower and the Administrative Agent otherwise consent, provided that no such consent of the Borrower shall be required if an Event of Default has occurred and is continuing;

(B) each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement;

(C) the parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Assumption, together with a processing and recordation fee of $3,500; and

(D) the assignee, if it shall not be a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire.

For the purposes of this Section, the term “ Approved Fund ” and “ Ineligible Institution ” have the following meanings:

“ Approved Fund ” means any Person (other than a natural person) that is engaged in making, purchasing, holding or investing in bank loans and similar extensions of credit in the ordinary course of its business (excluding, for the avoidance of doubt, any investor a material part of whose business activity is investing in debt of entities with a view to acquiring an equity interest in such entities or its holding companies) and that is administered or managed by (a) a Lender, (b) an Affiliate of a Lender or (c) an entity or an Affiliate of an entity that administers or manages a Lender.

“ Ineligible Institution ” means (a) a natural person, (b) a Defaulting Lender or its Lender Parent, (c) a company, investment vehicle or trust for, or owned and operated for the primary benefit of, a natural person or relative(s) thereof, or (d) the Borrower or any of its Affiliates; provided that such company, investment vehicle or trust shall not constitute an Ineligible Institution if it (x) has not been established for the primary purpose of acquiring any Loans or Commitments, (y) is managed by a professional advisor, who is not such natural person or a relative thereof, having significant experience in the business of making or purchasing commercial loans, and (z) has assets greater than $25,000,000 and a significant part of its activities consist of making or purchasing commercial loans and similar extensions of credit in the ordinary course of its business; provided that upon the occurrence of an Event of Default, any Person (other than a Lender) shall be an Ineligible Institution if after giving effect any proposed assignment to such Person, such Person would hold more than 25% of the then outstanding Total Revolving Exposure or Commitments, as the case may be.

(iii) Subject to acceptance and recording thereof pursuant to Section 9.04(b)(iv) , from and after the effective date specified in each Assignment and Assumption the assignee thereunder shall be a party hereto and, to the extent of the interest assigned by such Assignment and Assumption, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto but shall continue to be entitled to the benefits of Sections 2.14 , 2.15 , 2.16 and 9.03 ). Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with Section 9.04(c) .

(iv) The Administrative Agent, acting for this purpose as a non-fiduciary agent of the Borrower, shall maintain at one of its offices a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitment of, and principal amount (and stated interest) of the Loans and LC Disbursements owing to, each Lender pursuant to the terms hereof from time to time (the “ Register ”). The entries in the Register shall be conclusive, and the Borrower, the Administrative Agent, the Issuing Bank and the Lenders shall treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower, the Issuing Bank and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

(v) Upon its receipt of a duly completed Assignment and Assumption executed by an assigning Lender and an assignee, the assignee’s completed Administrative Questionnaire (unless the assignee shall already be a Lender hereunder), the processing and recordation fee referred to in Section 9.04(b) and any written consent to such assignment required by Section 9.04(b) , the Administrative Agent shall accept such Assignment and Assumption and record the information contained therein in the Register; provided that if either the assigning Lender or the assignee shall have failed to make any payment required to be made by it pursuant to this Agreement, the Administrative Agent shall have no obligation to accept such Assignment and Assumption and record the information therein in the Register unless and until such payment shall have been made in full, together with all accrued interest thereon. No assignment shall be effective for purposes of this Agreement unless it has been recorded in the Register as provided in this Section 9.04(b)(v) .

(c) Any Lender may, without the consent of the Borrower, the Administrative Agent or the Issuing Bank, sell participations to one or more banks or other entities (a “ Participant ”), other than an Ineligible Institution, in all or a portion of such Lender’s rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans owing to it); provided that (A) such Lender’s obligations under this Agreement shall remain unchanged; (B) such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations; and (C) the Borrower, the Administrative Agent, the Issuing Bank and the other Lenders shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without the consent of the Participant, agree to any amendment, modification or waiver described in the first proviso to Section 9.02(b) that affects such Participant. The Borrower agrees that each Participant shall be entitled to the benefits of Section 2.14 , Section 2.15 , Section 2.16 (subject to the requirements and limitations therein, including the requirements under Sections 2.16(f) and (g) (it being understood that the documentation required under Section 2.16(f) shall be delivered to such participating Lender and the information and documentation required under Section 2.16(g)

will be delivered to the Borrower and the Administrative Agent)) to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to Section 9.04(b) ; provided that such Participant (A) agrees to be subject to the provisions of Section 2.18 as if it were an assignee under Section 9.04(b) ; and (B) shall not be entitled to receive any greater payment under Section 2.15 or Section 2.16 , with respect to any participation, than its participating Lender would have been entitled to receive, except to the extent such entitlement to receive a greater payment results from a Change in Law that occurs after the Participant acquired the applicable participation. Each Lender that sells a participation agrees, at the Borrower’s request and expense, to use reasonable efforts to cooperate with the Borrower to effectuate the provisions of Section 2.18(b) with respect to any Participant. To the extent permitted by law, each Participant also shall be entitled to the benefits of Section 9.08 as though it were a Lender, provided that such Participant agrees to be subject to Section 2.17(c) as though it were a Lender. Each Lender that sells a participation shall, acting solely for this purpose as a non-fiduciary agent of the Borrower, maintain a register on which it enters the name and address of each Participant and the principal amounts (and stated interest) of each Participant’s interest in the Loans or other obligations under the Loan Documents (the “ Participant Register ”); provided that no Lender shall have any obligation to disclose all or any portion of the Participant Register to any Person (including the identity of any Participant or any information relating to a Participant’s interest in any Commitments, Loans, Letters of Credit or its other obligations under any Loan Document) to any Person except to the extent that such disclosure is necessary to establish that such Commitment, Loan, Letter of Credit or other obligation is in registered form under Section 5f.103-1(c) of the United States Treasury Regulations. The entries in the Participant Register shall be conclusive absent manifest error, and such Lender shall treat each Person whose name is recorded in the Participant Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary. For the avoidance of doubt, the Administrative Agent (in its capacity as Administrative Agent) shall have no responsibility for maintaining a Participant Register.

(d) Any Lender may at any time pledge or assign a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender to a Federal Reserve Bank, and this Section shall not apply to any such pledge or assignment of a security interest; provided that no such pledge or assignment of a security interest shall release a Lender from any of its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto.

SECTION 9.05 Survival . All covenants, agreements, representations and warranties made by the Loan Parties in the Loan Documents and in the certificates or other instruments delivered in connection with or pursuant to this Agreement or any other Loan Document shall be considered to have been relied upon by the other parties hereto and shall survive the execution and delivery of the Loan Documents and the making of any Loans and issuance of any Letters of Credit, regardless of any investigation made by any such other party or on its behalf and notwithstanding that the Administrative Agent, the Issuing Bank or any Lender may have had notice or knowledge of any Default or incorrect representation or warranty at the time any credit is extended hereunder, and shall continue in full force and effect as long as the principal of or any accrued interest on any Loan or any fee or any other amount payable under this Agreement is outstanding and unpaid or any Letter of Credit is outstanding and so long as the Commitments

have not expired or terminated. The provisions of Sections 2.12(e) , 2.14 , 2.15 , 2.16 and 9.03 and Article VIII shall survive and remain in full force and effect regardless of the consummation of the transactions contemplated hereby, the repayment of the Loans, the expiration or termination of the Letters of Credit and the Commitments or the termination of this Agreement or any provision hereof.

SECTION 9.06 Counterparts; Integration; Effectiveness; Electronic Execution .

This Agreement, the other Loan Documents and any separate letter agreements with respect to (i) fees payable to the Administrative Agent and (ii) the reductions of the Letter of Credit Commitment constitute the entire contract among the parties relating to the subject matter hereof and supersede any and all previous agreements and understandings, oral or written, relating to the subject matter hereof.

(b) Except as provided in Section 4.01 , this Agreement shall become effective when it shall have been executed by the Administrative Agent and when the Administrative Agent shall have received counterparts hereof which, when taken together, bear the signatures of each of the other parties hereto, and thereafter shall be binding upon and inure to the benefit of the parties hereto and their respective successors and assigns. Delivery of an executed counterpart of a signature page of this Agreement by telecopy shall be effective as delivery of a manually executed counterpart of this Agreement.

(c) Delivery of an executed counterpart of a signature page of this Agreement by telecopy, emailed pdf. or any other electronic means that reproduces an image of the actual executed signature page shall be effective as delivery of a manually executed counterpart of this Agreement.

SECTION 9.07 Severability . Any provision of this Agreement held to be invalid, illegal or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality or unenforceability without affecting the validity, legality and enforceability of the remaining provisions hereof; and the invalidity of a particular provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction.

SECTION 9.08 Right of Setoff . If an Event of Default shall have occurred and be continuing, each Lender and each of its Affiliates is hereby authorized at any time and from time to time, to the fullest extent permitted by law, to set off and apply any and all deposits (general or special, time or demand, provisional or final) at any time held and other obligations at any time owing by such Lender or Affiliate to or for the credit or the account of the Borrower against any of and all the obligations of the Borrower now or hereafter existing under this Agreement held by such Lender, irrespective of whether or not such Lender shall have made any demand under this Agreement and although such obligations may be unmatured. The rights of each Lender under this Section are in addition to other rights and remedies (including other rights of setoff) which such Lender may have.

SECTION 9.11 Headings . Article and Section headings and the Table of Contents used herein are for convenience of reference only, are not part of this Agreement and shall not affect the construction of, or be taken into consideration in interpreting, this Agreement.

SECTION 9.12 Interest Rate Limitation . Borrower and the Lenders intend to strictly comply with all applicable federal and New York laws, including applicable usury laws (or the usury laws of any jurisdiction whose usury laws are deemed to apply to the Notes or any other Loan Documents despite the intention and desire of the parties to apply the usury laws of the State of New York). Accordingly, the provisions of this Section shall govern and control over every other provision of this Agreement or any other Loan Document which conflicts or is inconsistent with this Section, even if such provision declares that it controls. As used in this Section, the term “interest” includes the aggregate of all charges, fees, benefits or other compensation which constitute interest under applicable law, provided that, to the maximum extent permitted by applicable law, (a) any non-principal payment shall be characterized as an expense or as compensation for something other than the use, forbearance or detention of money and not as interest, and (b) all interest at any time contracted for, reserved, charged or received shall be amortized, prorated, allocated and spread, using the actuarial method, during the full term of the Notes. In no event shall Borrower or any other Person be obligated to pay, or any Lender have any right or privilege to reserve, receive or retain, (a) any interest in excess of the maximum amount of nonusurious interest permitted under the laws of the State of New York or the applicable laws (if any) of the United States or of any other jurisdiction, or (b) total interest in excess of the amount which such Lender could lawfully have contracted for, reserved, received, retained or charged had the interest been calculated for the full term of the Notes at the Highest Lawful Rate.

None of the terms and provisions contained in this Agreement or in any other Loan Document (including, without limitation, Article VII hereof) which directly or indirectly relate to interest shall ever be construed without reference to this Section, or be construed to create a contract to pay for the use, forbearance or detention of money at any interest rate in excess of the Highest Lawful Rate. If the term of any Note is shortened by reason of acceleration or maturity as a result of any Default or by any other cause, or by reason of any required or permitted prepayment, and if for that (or any other) reason any Lender at any time, including but not limited to, the stated maturity, is owed or receives (and/or has received) interest in excess of interest calculated at the Highest Lawful Rate, then and in any such event all of any such excess interest shall be canceled automatically as of the date of such acceleration, prepayment or other event which produces the excess, and, if such excess interest has been paid to such Lender, it shall be credited pro tanto against the then-outstanding principal balance of Borrower’s obligations to such Lender, effective as of the date or dates when the event occurs which causes it to be excess interest, until such excess is exhausted or all of such principal has been fully paid and satisfied, whichever occurs first, and any remaining balance of such excess shall be promptly refunded to its payor.

SECTION 9.13 Keepwell . Each Qualified ECP Loan Party hereby jointly and severally absolutely, unconditionally and irrevocably undertakes to provide such funds or other support as may be needed from time to time by each other Loan Party to honor all of its obligations under any Loan Document in respect of Swap Obligations (provided, however, that each Qualified ECP Loan Party shall only be liable under this Section for the maximum amount of such liability that can be hereby incurred without rendering its obligations under this Section or otherwise under any applicable Loan Document voidable under applicable law relating to fraudulent conveyance or fraudulent transfer, and not for any greater amount). Each Qualified ECP Loan Party intends that this Section constitute, and this Section shall be deemed to constitute, a “keepwell, support, or other agreement” for the benefit of each other Loan Party for all purposes of Section 1a(18)(A)(v)(II) of the Commodity Exchange Act.

SECTION 9.14 Patriot Act . Each Lender that is subject to the requirements of the Patriot Act hereby notifies the Borrower that pursuant to the requirements of the Patriot Act, it is required to obtain, verify and record information that identifies the Borrower, which information includes the name and address of the Borrower and other information that will allow such Lender to identify the Borrower in accordance with the Patriot Act.

SECTION 9.15 Other Agents . Any Lender identified herein as a lead arranger, arranger or any other corresponding title, other than “Administrative Agent” shall have no right, power, obligation, liability, responsibility or duty under this Agreement or any other Loan Document except those applicable to all Lenders as such. Each Lender acknowledges that it has not relied, and will not rely, on any Lender so identified in deciding to enter into this Agreement or in taking or not taking any action hereunder.

SECTION 9.16 Acknowledgement and Consent to Bail-In of EEA Financial Institutions . Notwithstanding anything to the contrary in any Loan Document or in any other agreement, arrangement or understanding among any such parties, each party hereto acknowledges that any

100

liability of any EEA Financial Institution arising under any Loan Document, to the extent such liability is unsecured, may be subject to the Write-Down and Conversion Powers of an EEA Resolution Authority and agrees and consents to, and acknowledges and agrees to be bound by:

(a) the application of any Write-Down and Conversion Powers by an EEA Resolution Authority to any such liabilities arising hereunder which may be payable to it by any party hereto that is an EEA Financial Institution; and

(b) the effects of any Bail-In Action on any such liability, including, if applicable:

(i) a reduction in full or in part or cancellation of any such liability;

(ii) conversion of all, or a portion of, such liability into shares or other instruments of ownership in such EEA Financial Institution, its parent entity, or a bridge institution that may be issued to it or otherwise conferred on it, and that such shares or other instruments of ownership will be accepted by it in lieu of any rights with respect to any such liability under this Agreement or any other Loan Document; or

(iii) the variation of the terms of such liability in connection with the exercise of the Write-Down and Conversion Powers of any EEA Resolution Authority.

SECTION 9.17 Certain ERISA Matters .

(a) Each Lender (x) represents and warrants, as of the date such Person became a Lender party hereto, to, and (y) covenants, from the date such Person became a Lender party hereto to the date such Person ceases being a Lender party hereto, for the benefit of, the Administrative Agent, and not, for the avoidance of doubt, to or for the benefit of the Borrower or any other Loan Party, that at least one of the following is and will be true :

(ii) the transaction exemption set forth in one or more PTEs, such as PTE 84-14 (a class exemption for certain transactions determined by independent qualified professional asset managers), PTE 95-60 (a class exemption for certain transactions involving insurance company general accounts), PTE 90-1 (a class exemption for certain transactions involving insurance company pooled separate accounts), PTE 91-38 (a class exemption for certain transactions involving bank collective investment funds) or PTE 96-

101

23 (a class exemption for certain transactions determined by in-house asset managers), is applicable with respect to such Lender’s entrance into, participation in, administration of and performance of the Loans, the Letters of Credit, the Commitments and this Agreement;

(iii) (A) such Lender is an investment fund managed by a “Qualified Professional Asset Manager” (within the meaning of Part VI of PTE 84-14), (B) such Qualified Professional Asset Manager made the investment decision on behalf of such Lender to enter into, participate in, administer and perform the Loans, the Letters of Credit, the Commitments and this Agreement, (C) the entrance into, participation in, administration of and performance of the Loans, the Letters of Credit, the Commitments and this Agreement satisfies the requirements of sub-sections (b) through (g) of Part I of PTE 84-14 and (D) to the best knowledge of such Lender, the requirements of subsection (a) of Part I of PTE 84-14 are satisfied with respect to such Lender’s entrance into, participation in, administration of and performance of the Loans, the Letters of Credit, the Commitments and this Agreement; or

(iv) such other representation, warranty and covenant as may be agreed in writing between the Administrative Agent, in its sole discretion, and such Lender.

(b) In addition, unless either (1) sub-clause (i) in the immediately preceding clause (a) is true with respect to a Lender or (2) a Lender has provided another representation, warranty and covenant in accordance with sub-clause (iv) in the immediately preceding clause (a), such Lender further (x) represents and warrants, as of the date such Person became a Lender party hereto, to, and (y) covenants, from the date such Person became a Lender party hereto to the date such Person ceases being a Lender party hereto, for the benefit of, the Administrative Agent and not, for the avoidance of doubt, to or for the benefit of the Borrower or any other Loan Party, that the Administrative Agent is not a fiduciary with respect to the assets of such Lender involved in such Lender’s entrance into, participation in, administration of and performance of the Loans, the Letters of Credit, the Commitments and this Agreement (including in connection with the reservation or exercise of any rights by the Administrative Agent under this Agreement, any Loan Document or any documents related hereto or thereto).

SECTION 9.18 Amendment and Restatement . This Agreements amends and restates in its entirety that certain Credit Agreement dated as of January 19, 2018 executed by and among Woodforest National Bank, as administrative agent, certain lenders therein named, and Borrower (as the same may have been amended prior to the date hereof) (the “ Existing Credit Agreement ”).

On the date hereof, and after giving effect to such reallocations, adjustments, assignments and decreases, the Commitment of each Lender shall be as set forth on Schedule 2.01A . The Lenders shall make all appropriate adjustments and payments between and among themselves to account for the revised pro rata shares resulting from the initial allocation of the Lenders’ commitments under the Existing Credit Agreement after adjustment as provided for by this Agreement. The Borrower and each Lender party hereto that was a “Lender” under the Existing Credit Agreement hereby agrees and this Section 9.18, and any exiting agreement executed by an Exiting Lender that is acceptable to the Administrative Agent and the Borrower, shall be deemed approved assignment forms as required under the Existing Credit Agreement.
