OPEN Business Club AG Acquires Neurona, the Spanish Market Leader for Online Business Networking

OPEN Business Club AG (GER:O1BC) (ISIN: DE000XNG8888), operator of XING – one of the world’s leading networks for business professionals – has acquired a 100% interest in Neurona (www.neurona.com), the largest contact online business network in Spain and Latin America. The acquisition of Neurona enables XING to position itself as the clear market leader in the field of online networking for business professionals in the Spanish-speaking world. This acquisition is further proof of OPEN Business Club’s global ambitions, following the company’s successful US market entry last week. Until the acquisition, Neurona was operated by the Spanish company "Grupo Intercom Factory, S.L.” which is involved in projects in the fields of technology and online business in Spain and holds numerous active participations in other Internet firms. The purchase of Neurona coupled with OPEN Business Club’s takeover of eConozco in March 2007 means that the Spanish market is now the second key market – besides the German-speaking world – where OPEN Business Club has secured clear market leadership over its global competitors. All parties involved in the acquisition have agreed not to disclose terms of payment. "XING is the only global business network that drives international business simultaneously in multiple languages across multiple continents. With over 420 million native speakers and more than 90 million Web users, the Spanish-speaking market is one of the world’s fastest growing online markets. The company "Grupo Intercom Factory, S.L.” has a reputation for developing the most successful online portals in this market, and we’re excited to have such a capable partner on board, whose track record in the Spanish market will be of great value in the future,” said Lars Hinrichs, Founder and CEO of OPEN Business Club AG. The takeover will expand XING’s already strong presence in the financial centers Madrid and Barcelona to include Mexico City, Buenos Aires, Lima and Bogotá. Members currently use Neurona free-of-charge. With integration into the XING Web site, OPEN Business Club AG nevertheless expects existing Neurona members to become increasingly willing to pay for the comprehensive functionalities of XING’s Premium Membership. Neurona members will benefit from the active international XING community, as well as from the well-engineered XING technology and the company’s focus on business professionals worldwide. After completion of the integration, all Neurona members will have access to more comprehensive functionalities of the XING platform. The actual integration on to the XING platform is scheduled to begin at the end of 2007: The user interface and the design will be gradually migrated to reflect the look and functionality of the XING platform. This progression towards the new, combined network is largely a matter of simplification and are expected to be completed within a twelve-month period. Ferran Aznar, Managing Director and Co-Founder of Neurona, will manage Neurona operations as a subsidiary company of OPEN Business Club AG in the interim working with a team of eleven employees, and assume responsibility for Neurona’s role in the integration.
