| Schedule of Business Acquisition | 
 
 The following details the fair value of the consideration
 transferred to effect the ITS Acquisition (dollars in
 thousands). 
   
 
 |  |  |  |  |  |  
 | 
 Cash paid to, or on behalf of, ITS and its equity holders |  | $ | 101,000 |  |  
 | 
 Cash deposited in escrow |  |  | 19,000 |  |  
 | 
 Fair value of contingent consideration deposited in escrow for
 assets not acquired(1) |  |  | 5,000 |  |  
 |  |  |   |   |  |  
 | 
 Total fair value of the consideration transferred |  | $ | 125,000 |  |  
 |  |  |   |   |  |  
   
 
 |  | (1) | Based on the terms of the Agreement,
 $5.0 million of the $24.0 million in escrow to be paid to the
 seller is contingent upon certain future liabilities that could
 become due by ITS in certain jurisdictions. Any payments in
 relation to these liabilities will be deducted from the $5.0
 million escrow amount and the net balance of the escrow will be
 paid to the seller. We estimate that the entire $5.0 million in
 escrow will be paid to the seller, and therefore, the estimated
 fair value of the consideration in escrow related to these
 liabilities is $5.0 million. We do not expect to receive any amount
 back from escrow, and therefore did not record a receivable from
 the escrow. Any changes to the fair value of the contingent
 consideration in the future of less than $5.0 million will result
 in recording a receivable from escrow. The receivable will be
 recorded at fair value. As of September 30, 2013, the fair
 value of the receivable is $0.0 million. |  
 Preliminary Allocation of Consideration Transferred to Net
 Assets Acquired 
 The following amounts represent the preliminary estimates of fair
 value of identifiable assets acquired and liabilities assumed in
 the ITS Acquisition and are based on management’s estimates,
 judgments and assumptions. These estimates, judgments and
 assumptions are subject to change upon final valuation and should
 be treated as preliminary values. Management estimated that the
 fair value of the net assets acquired less noncontrolling interest
 equals consideration paid. Therefore, there was no goodwill
 recorded. 
   
 The final allocation of consideration will include changes in
 (1) amounts deposited in escrow, (2) estimated fair
 values of property and equipment, (3) allocations to
 intangible assets and liabilities, (4) changes in contingent
 consideration, and (5) other assets and liabilities. These
 amounts will be finalized as soon as possible, but no later than
 one year from the acquisition date.

 |  | (1) | Gross contractual amounts receivable
 totaled $54.7 million as of the acquisition date. |  
 
 |  | (2) | We recorded an adjustment of $43.7
 million to reduce the historical carrying value of the acquired
 property, plant and equipment to its estimated fair value. |  
 
 |  | (3) | In connection with the ITS
 Acquisition, we recorded a $7.7 million adjustment to increase
 deferred income tax assets primarily related to the differences
 between acquisition date estimated fair value and tax basis of
 acquired property, plant and equipment. |  
 
 |  | (4) | We recorded $10.0 million and $0.2
 million to reflect the estimated fair values of definite and
 indefinite lived intangible assets, respectively, recognized in
 connection with the ITS Acquisition. Our depreciation and
 amortization expense will reflect this valuation adjustment as the
 definite lived intangible assets are amortized in future periods.
 Definite lived intangible assets recorded in connection with the
 ITS Acquisition, which primarily relate to trade names, customer
 relationships, and developed technology will be amortized over a
 weighted average period of approximately 3.4 years. |  
 
 |  | (5) | We recorded an adjustment of $1.0
 million to write-down the noncontrolling interest to its estimated
 fair value. The estimated fair value of the noncontrolling interest
 was calculated as a percentage of the net assets acquired related
 to certain subsidiaries in which ITS holds less than a 100 percent
 controlling interest. The fair value of the net assets of these
 subsidiaries was primarily based on the income approach valuation
 model. |  | 
      
        | Schedule of Pro Forma Information for Business Acquisition | 
 
 The following unaudited supplemental pro forma results present
 consolidated information for the nine months ended
 September 30, 2013 as if the ITS Acquisition had been
 completed on January 1, 2012. The pro forma results have
 been calculated after applying our accounting policies and include,
 among others, (i) the amortization associated with the fair
 value of the acquired intangible assets, (ii) interest expense
 associated with the Goldman Term Loan and (iii) the impact of
 certain fair value adjustments such as a decrease in depreciation
 expense related to the write-down in property, plant and equipment.
 The pro forma results do not include any potential synergies,
 non-recurring charges which result directly from the ITS
 Acquisition, cost savings or other expected benefits of the ITS
 Acquisition. The pro forma financial information does not
 necessarily represent what would have occurred if the transaction
 had taken place at the beginning of the period presented and should
 not be taken as representative of our future consolidated results
 of operations. We have not concluded our integration work.
 Accordingly, this pro forma information does not include all costs
 related to the integration nor the benefits we expect to realize
 from operating synergies.
