UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

The following Unaudited Pro Forma Condensed Combined Balance Sheet as of March 31, 2014 and the Unaudited Pro Forma Condensed Combined Statements of Operations for the nine months ended March 31, 2014 and the year ended June 30, 2013, giving effect to the business combination and certain other transactions and are based upon:

(a) the audited combined balance sheets of Lone Star Tank Rental LP and KHM Rentals, LLC (collectively “Lone Star”) as of December 31, 2013 and 2012, and the related combined statements of operations for the years then ended, included in this Form 8-K/A;

(b) the unaudited combined balance sheet of Lone Star as of March 31, 2014, and the related combined statement of operations for the quarter ended March 31, 2014, included in this Form 8-K/A;

(c) our audited consolidated statements of operations for the year ended June 30, 2013, included in our Annual Report on Form 10-K for the year ended June 30, 2013; and

(d) our unaudited condensed consolidated balance sheet as of March 31, 2014, and the related condensed consolidated statements of operations for the nine months then ended, included in our Quarterly Report on Form 10-Q for the quarter ended March 31, 2014.

The Unaudited Pro Forma Condensed Combined Statements of Operations gives effect to the business combination as if it had occurred on the first day of each period and the Unaudited Pro Forma Condensed Combined Balance Sheet gives effect to the business combination as if it had occurred on the date of such balance sheet. The unaudited statements of operations of Lone Star for the year ended June 30, 2013 (“FY 2013”) were derived by combining the unaudited results for the six-month period from July 1, 2012 to December 31, 2012 with the unaudited results for the six-month period from January 1, 2013 to June 30, 2013, and the unaudited statements of operations of Lone Star for the nine months ended March 31, 2014 (“FY 2014”) were derived by subtracting the unaudited results for the six-month period from January 1, 2013 to June 30, 2013 from the audited results for the year ended December 31, 2013 (Lone Star’s fiscal year end is December 31) and adding the unaudited results for the quarter ended March 31, 2014.

The Unaudited Pro Forma Condensed Combined Financial Statements do not purport to represent what our actual consolidated results of operations or the consolidated financial position would have been had the business combination with Lone Star occurred on the respective dates assumed, nor are they necessarily indicative of our future consolidated operating results or of our future consolidated financial position. In addition, they do not consider any potential impacts of current market conditions on revenues, any staff or related expense increases or efficiencies or asset dispositions.

The Unaudited Pro Forma Condensed Combined Financial Statements should be read in conjunction with our audited consolidated financial statements and the accompanying notes, our unaudited condensed consolidated financial statements and the accompanying notes and Lone Star’s combined financial statements and accompanying notes.

We will account for the business combination as a purchase of Lone Star in accordance with generally accepted accounting principles in the United States. Accordingly, the estimated aggregate fair value of the consideration paid by us will be allocated to Lone Star’s assets based on their estimated fair values as of the completion of the business combination. The difference between the estimated fair value of Lone Star’s identifiable tangible and intangible assets and liabilities and the estimated aggregate fair value of the consideration paid will be recorded as goodwill. The results of operations of Lone Star will be included in our consolidated results of operations only for periods subsequent to the effective date of the business combination.

Purchase Accounting Adjustments

Purchase accounting adjustments include adjustments necessary to allocate the estimated aggregate fair value of the purchase consideration paid to the identifiable tangible and intangible assets acquired and liabilities assumed of Lone Star based on their estimated fair values. A description of each of these purchase accounting adjustments follows:

Fair Value Adjustments: The pro forma financial statements reflect the purchase price allocation based on a preliminary assessment of the estimated fair values and lives assigned to the identifiable tangible and intangible assets acquired and liabilities assumed. Estimated fair values in the pro forma financial statements were determined based upon preliminary discussions with independent valuation consultants and upon available information and assumptions that we believe are reasonable. After the closing

of the business combination, we will complete the evaluation of the fair values of assets and liabilities with the assistance of the independent valuation consultants. Estimated fair value adjustments reflected in the pro forma financial statements may be subject to significant revisions and adjustments pending finalization of those valuation studies.

Transaction Costs: We estimate that we will incur approximately $750,000 of transaction and related costs, consisting primarily of financial advisory, legal and accounting fees and other incremental out-of-pocket charges related to the purchase of Lone Star. These estimates are preliminary and, therefore, are subject to change. Transaction costs were expensed as incurred and are accrued in the Unaudited Pro Forma Condensed Combined Balance Sheet, but were not included in the Unaudited Pro Forma Condensed Combined Statements of Operations.

Purchase Consideration Allocation: The purchase consideration consisted of (i) $75,000,000 in cash, (ii) 1,230,012 shares of our common stock (the number of shares was agreed to based on a value of $8.13 per share, which was the average of the closing market price during the 15-day trading period ending April 2, 2014), (iii) $5,000,000 payable over five years for a non-compete agreement, (iv) $5,000,000 payable over two years for a general indemnity holdback and (v) an estimated payable for working capital, as defined, in excess of $1,000,000. The non-compete and indemnity holdback notes are non-interest bearing and, therefore, were discounted using an estimated market interest rate of 10.5%. We funded the cash portion of the consideration using $50 million from availability under an amended and expanded senior secured revolving credit facility with a syndicate led by Wells Fargo, National Association (the “Wells Fargo Credit Facility”) and $25 million at the corporate level from a two-year secured term loan from Credit-Suisse AG.

The following table summarizes the estimated purchase consideration (in thousands):

(1) 1,230,012 of our shares of common stock at a per share price of $8.02, the closing price of our common stock at April 7, 2014, which was the closing date of the business combination.

The following table summarizes the pro forma net assets acquired and liabilities assumed in connection with the business combination and the preliminary allocation of the purchase consideration at March 31, 2014 (in thousands):

Income Taxes: Since prior to the effective date of the business combination federal income taxes otherwise payable flowed through to the former owners of Lone Star and we are buying the assets of the business versus purchasing stock ownership, no significant adjustment for deferred taxes is necessary. Normally, any such adjustment would be recorded as an offset to goodwill.

Reclassification: The historical financial statements of Lone Star reflect reclassifications of certain balances in order to conform to our financial statement presentation.
