class="_mt"&gt;In October 2009, we acquired substantially all of the assets of the Houston operations of Atlas Engineering, Inc., a privately held company, for a purchase price of approximately $21,000. The purchase price may be increased by an estimated $12,000 for contingent consideration depending on the acquired company's EBITDA, as defined in the purchase agreement for this transaction, over the first three years after the closing date. We have recorded a liability of $9,318 on the consolidated balance sheet for the estimated fair value of the contingent consideration. &lt;font
class="_mt"&gt; &lt;/font&gt;The acquired company is active in upstream oil and gas engineering services. The purchase price allocation and pro forma information for this acquisition were not material to our consolidated financial statements. &lt;/font&gt;&lt;font

class="_mt"&gt;This company's financial results are included within our Global E&amp;amp;C Group business segment.&lt;/font&gt;&lt;font

class="_mt"&gt;we acquired substantially all of the assets of the offshore engineering division of OPE Holdings Ltd., a Canadian company that is listed on the TSX Venture Exchange and which we refer to as OPE, for a purchase price of approximately $8,900.&lt;font
class="_mt"&gt;&amp;nbsp; &lt;/font&gt;The purchase price may be increased by $500 if the acquired company meets certain performance targets during the first year after the closing date.&lt;font
