BUSINESS ACQUISITIONS

Early Discovery UK

On April 1, 2014, we acquired theCRO services divisionof Galapagos N.V., which includes both the Argenta and BioFocus businesses, and which consist of UK entities and certain Dutch assets including a facility lease and equipment, and the transfer of employees (collectively Early Discovery UK). We expect that the acquisition will enhance our position as a full service, early-stage CRO, with integrated in vitro and in vivo capabilities from target discovery through preclinical development. The preliminary purchase price of the acquisition is $190,727 in cash and up to an additional$6,887 in contingent consideration. The purchase price includes payment for estimated working capital, which is subject to final adjustment based on the actual working capital of the acquired business. We are currently in the process of determining the allocation of the purchase price to the fair value of assets and liabilities acquired.
