On December 16, 2005, Diamondback acquired substantially all of the assets of Quantum Drilling Motors, L.L.C. (an Oklahoma limited liability company). The acquisition formed the platform for Diamondbacks drilling technology services and applications segment and is included in Diamondbacks results of operations from December 1, 2005, the designated effective date. The purchase price was allocated to the assets acquired, including intangible assets, and liabilities assumed at estimated fair values.

As a result, goodwill, customer relationships, property and equipment and current liabilities were adjusted. The excess of cost of the acquisition over the net of amounts assigned to fair value of the assets acquired and liabilities assumed is recorded as goodwill.
