Mergers and Acquisitions can be very exciting events for organizations. The promise of top and bottom line growth through synergy with another company can excite executives. Unfortunately, research has shown, this promise very seldom realizes as acquisitions are complex process that require understanding and commitment from all parties, both from the acquiring firm and the acquired firm. The study will start off reviewing the processes that define, in general terms, implementation of mergers and acquisitions. This will be following by a review of the experience of the SASOL Oil acquisition of EXEL Petroleum. A detail investigation of the actual process adopted by the latter organizations will be investigated through empirical research. And finally, the focus of this review is to identify gaps, a lack of certain process and their implementation and statements and actions of ambiguities and ambiguous situations. The resultant outcome of this investigation will assist the researcher, in establishing whether the acquisition of EXEL Petroleum by SASOL Oil provided synergistic value, and whether the implementation of the integration process was thorough and successful. / Prof. A.
