Independent Auditors’ Report

To the Partners and Members

of Lone Star Tank Rental, LP and KHM Rentals, LLC

We have audited the accompanying combined financial statements of Lone Star Tank Rental, LP and KHM Rentals, LLC (a Texas Limited Partnership and Limited Liability Company, respectively), which comprise the combined balance sheets as of December 31, 2013 and 2012, and the related combined statements of operations, partners’ and members’ equity, and cash flows for the years then ended, and the related notes to the combined financial statements.

Management’s Responsibility for the Financial Statements

Management is responsible for the preparation and fair presentation of the combined financial statements in accordance with accounting principles generally accepted in the United States of America; this includes the design, implementation, and maintenance of internal control relevant to the preparation and fair presentation of combined financial statements that are free from material misstatement, whether due to fraud or error.

Auditor’s Responsibility

Our responsibility is to express an opinion on these combined financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the combined financial statements are free from material misstatement.

An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the combined financial statements. The procedures selected depend on the auditor’s judgment, including the assessment of the risks of material misstatement of the combined financial statements, whether due to fraud or error. In making those risk assessments, the auditor considers internal control relevant to the entity’s preparation and fair presentation of the combined financial statements in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the entity’s internal control. Accordingly, we express no such opinion. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of significant accounting estimates made by management, as well as evaluating the overall presentation of the combined financial statements.

We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.

Opinion

In our opinion, the combined financial statements referred to above present fairly, in all material respects, the financial position of Lone Star Tank Rental, LP and KHM Rentals, LLC as of December 31, 2013 and 2012, and the results of their operations and their cash flows for the years then ended in accordance with accounting principles generally accepted in the United States of America.

Notes to Combined Financial Statements

Note 1 – Organization and Summary of Significant Accounting Policies

Organization - Lone Star Tank Rental, LP (“Lone Star”) is a Texas Limited Partnership formed in 2000. KHM Rentals, LLC (“KHM”) is a Texas Limited Liability Company formed in 2011. Lone Star Tank Rental, LP and KHM Rentals, LLC (collectively, the “Companies” or “Company”) provide portable liquid storage tank container (“tank”) rental and related services to driller and oil field service operators. Lone Star operates within the Permian Basin (West Texas) and KHM operates within the Eagle Ford (South Texas) regions of Texas.

Basis of Presentation - The Companies have common partners and members; however, no parent/subsidiary relationship exists between the Companies. All intercompany transactions have been eliminated in the accompanying combined financial statements.

Use of Estimates - The preparation of combined financial statements in accordance with generally accepted accounting principles in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the combined financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

Accounts Receivable and Allowance for Doubtful Accounts - The Company extends credit to its customers. Trade receivables are recorded at net realizable value based on management’s estimate of uncollectible accounts recorded in the allowance for doubtful accounts. The Company does not typically accrue interest on their trade receivables.

The allowance for doubtful accounts is maintained at a level that, in management’s judgment, is adequate to absorb probable losses. The amount is based upon an analysis of overall receivables by management. Management’s evaluation of the allowance for doubtful accounts includes, but is not limited to, the historical experience of payment pattern from customers, financial condition of customers, other known facts and circumstances, and general economic conditions. This process is based on estimates and ultimate losses may vary from current estimates. As changes in estimates occur, adjustments to the level of the allowance are recorded in the provision for doubtful accounts in the period in which they become known. No write-offs or recoveries have been recorded in the allowance account during the periods presented.

Property and Equipment - Tanks are recorded at the lower of cost or market. Costs incurred on tank units subsequent to initial acquisition are capitalized when it is probable that future economic benefits in excess of the originally assessed performance will result. Tanks are depreciated on a straight-line basis over the estimated useful life of 20 years.

Other property and equipment are stated at cost. Expenditures for maintenance and repairs are charged to expense as incurred, while major renewals and betterments are capitalized. Upon disposal of depreciable property, the appropriate property accounts are reduced by the related costs and accumulated depreciation. The resulting gains and losses are reflected in the combined statement of operations. Depreciation is provided for in amounts sufficient to relate the costs of depreciable assets to operations over their estimated service lives, generally 5 to 20 years, using the straight-line method.

In the opinion of management, carrying values are at or below net realizable values. The Company continues to evaluate these depreciation policies as more information becomes available from other comparable sources and its own historical experience.

Notes to Combined Financial Statements

Note 1 – Organization and Summary of Significant Accounting Policies, Continued

Property and Equipment, continued - Capital leases - Leases under which substantially all the risks and benefits incidental to ownership of the leased assets are assumed by the Company are classified as capital leases. Other leases are classified as operating leases. A lease asset and a lease liability equal to the present value of the minimum lease payments, or the fair value of the leased item, whichever is the lower, are capitalized and recorded at the inception of the lease. Lease payments are apportioned between the finance charges and reduction of the lease liability so as to achieve a constant rate of interest on the remaining balance of the liability. Finance charges are charged directly to the statement of operations. Capitalized leased assets are depreciated over the shorter of the estimated useful life of the asset or the lease term.

Operating leases - Payments made under operating leases are expensed on the straight-line basis over the term of the lease, except where an alternative basis is more representative of the pattern of benefits to be derived from the leased property. Where leases have fixed rate increases, these increases are accrued and amortized over the entire lease period, yielding a constant periodic expense over the term of the lease.

Revenue Recognition - The Company’s primary source of revenue is from tank rentals. Rental revenues include recurring rental, delivery and installation, dismantling and return services, and other associated rental charges. Revenue is also generated from the sale of tank and other products; as well as professional services associated with delivery, installation, and maintenance.

The Company recognizes revenue when the following criteria are met: (a) persuasive evidence that an arrangement exists; (b) delivery of the products and/or services has occurred; (c) the price is both fixed and determinable and (d) collectability is reasonably assured. For arrangements with multiple deliverables where delivery, installation and/or dismantlement services are performed in addition to renting or selling related lease accessories, the Company recognizes revenue for each deliverable when the revenue recognition criteria are met. Each element of the arrangement has a price agreed upon by the Company and the customer.

The Company includes shipping and handling charges as revenue when earned and associated expenses in cost of rental operations when incurred.

Income Taxes - Lone Star, a limited partnership, and KHM, a limited liability company, are pass-through entities for income tax purposes and, as such, are not subject to federal income taxes. All items of taxable income, deductions and tax credits are passed through to and are reported by their owners on their respective income tax returns. Their federal tax status as pass-through entities is based on their legal status as a limited partnership and limited liability company, respectively. Each company is required to file tax returns with the Internal Revenue Service and other taxing authorities. Accordingly, these combined financial statements do not reflect a provision for federal income taxes for either Lone Star or KHM and management believes there are no other tax positions which must be considered for disclosure related to these entities.

The income tax as shown on the combined statements of operations reflects the Texas franchise tax for the respective period calculated at one percent of earned surplus.

The limited partnership and limited liability company’s returns for tax years 2011 and beyond remain subject to examination by the Internal Revenue Service. The limited partnership and limited liability company’s state franchise tax returns for the tax years 2010 and beyond remain subject to examination by the Texas Comptroller.

Notes to Combined Financial Statements

Note 1 – Organization and Summary of Significant Accounting Policies, Continued

Fair Value of Financial Instruments - Topic 825 in the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”), Financial Instruments, requires certain disclosures regarding the fair value of financial instruments. Cash, trade and other receivables, trade payables and accrued liabilities approximate fair value due to their short maturities. The fair value of the debt approximates its carrying value based on its effective interest rate compared to current market rates.

Cash - The cash balance at March 31, 2014, December 31, 2013 and 2012 represents cash only and contains no cash equivalents.

Recent Authoritative Guidance - From time to time, the FASB or other standards setting bodies issue new accounting pronouncements. Updates to the FASB Accounting Standards Codification are communicated through issuance of an Accounting Standards Update (“ASU”). Unless otherwise discussed, we believe that the impact of recently issued guidance, whether adopted or to be adopted in the future, is not expected to have a material impact on the combined financial statements upon adoption.

Proposed Amendments to Current Accounting Standards - The FASB is currently working on amendments to existing accounting standards governing a number of areas including, but not limited to, revenue recognition and lease accounting.

In June 2010, the FASB issued an exposure draft, Revenue from Contracts with Customers, which would supersede most of the existing guidance on revenue recognition in ASC Topic 605, Revenue Recognition. In November 2011, the FASB re-exposed this draft and the FASB expects a final standard to be issued in the year ending December 31, 2014. As the standard-setting process is still ongoing, the Company is unable to determine the impact this proposed change in accounting will have in its combined financial statements at this time.

In August 2010, the FASB issued an exposure draft, Leases, which would result in significant changes to the accounting requirements for both lessees and lessors in ASC Topic 840, Leases. In May 2013, the FASB re-exposed this draft and the comment period ended in September 2013. As the standard-setting process is still ongoing, the Company is unable to determine the impact this proposed change in accounting will have in its combined financial statements at this time.

The Company maintains its cash balances in two accounts at separate banks. At times, deposits held with the financial institutions may exceed the amount of insurance provided by the Federal Deposit Insurance Corporation (“FDIC”), which provides basic deposit coverage with limits up to $250,000 per account holder. Generally, these deposits may be redeemed upon demand and, therefore, are believed to bear minimal risk.
