On October 31, 2016, PRGX USA, Inc., a wholly owned subsidiary of PRGX Global, Inc. (PRGX Global, Inc. and PRGX USA, Inc. are collectively referred to as “PRGX”), consummated the merger of Braveheart Merger Co., a wholly owned subsidiary of PRGX USA, Inc., with and into Lavante, Inc. (the “Merger”) pursuant to the terms of that certain Agreement and Plan of Merger (the “Merger Agreement”) dated as of October 25, 2016 by and among PRGX USA, Inc., Braveheart Merger Co., Lavante, Inc. (“Lavante”), PointGuard Ventures I, L.P. and Krish Panu, as Stockholder Representative. Upon the consummation of the Merger, on October 31, 2016, Lavante continued as the surviving corporation of the Merger as a wholly-owned subsidiary of PRGX USA, Inc.

Lavante is a software-as-a-service-based procure-to-pay supplier information management (SIM) and recovery audit services firm, based in San Jose, California. Lavante’s assets consist primarily of its proprietary software applications and customer contracts.

At the closing of the transactions contemplated by the Merger Agreement, PRGX paid to or on behalf of Lavante stockholders $4.25 million in cash, as adjusted for Lavante’s current working capital and as further adjusted for amounts withheld for potential future payment to Lavante stockholders upon the receipt of specified third party consents and waivers (the “Closing Consideration”). The Closing Consideration is subject to a further customary working capital adjustment. In addition, PRGX may be required to pay earnout consideration in cash based on revenue received by PRGX and its subsidiaries (including Lavante) from SIM services from closing through December 31, 2018.

The foregoing description of the Merger Agreement and the transactions contemplated thereby does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement, a copy of which is attached hereto as Exhibit 2.1 to this Current Report on Form 8-K. PRGX issued a press release on November 1, 2016 regarding the closing of the Merger, a copy of which is attached as Exhibit 99.1 to this Current Report on Form 8-K.
