Edgewater Technology-Zero2Ten, Inc. (“Edgewater Technology-Zero2Ten”), a wholly owned subsidiary of Edgewater Technology, Inc. (“Edgewater” or the “Company”), entered into an Asset Purchase Agreement, dated as of March 13, 2015 (the “Purchase Agreement”), by and among Edgewater Technology-Zero2Ten, Zero 2 Ten, Inc., a Georgia corporation (“Zero2Ten”), Zero2Ten EMEA Limited, a wholly owned subsidiary of Zero2Ten organized under the laws of England and Wales (“Zero2Ten EMEA”), and Paul A. Colella, Ryan Casey, David T. Kohar and Adam Spurr. The Purchase Agreement provides for the acquisition of substantially all of the assets of Zero2Ten, including the outstanding shares of Zero2Ten EMEA held by Zero2Ten, and the assumption of certain liabilities (the “Acquisition”). The Acquisition was consummated on March 13, 2015.

The Company paid Zero2Ten upfront cash consideration of approximately $5.0 million, subject to a net working capital adjustment. In addition, Edgewater Technology-Zero2Ten and Zero2Ten entered into an Earnout Agreement, dated as of March 13, 2015 (the “Earnout Agreement”), pursuant to which Zero2Ten may receive additional contingent earnout consideration based upon the achievement of certain performance measures over a two-year period (the “Earnout Period”). The maximum amount of contingent earnout consideration to be earned during the Earnout Period is capped at approximately $8.6 million. Edgewater has guaranteed the payment of any earnout consideration earned by Zero2Ten.

The Acquisition will be accounted for as an asset purchase. The approximately $5.0 million in upfront cash consideration was funded from Edgewater’s working capital. The terms of the Acquisition were determined on the basis of arm’s-length negotiations.

Headquartered in Alpharetta, Georgia, Zero2Ten is a leading Microsoft Dynamics CRM Partner with over 800 clients worldwide.
