----------------------------------------------------------------------

Hamburg, June 22, 2007 – OPEN Business Club AG (ISIN: DE000XNG8888),
operator of the international networking platform XING (www.xing.com), has
acquired a 100% interest in Neurona (www.neurona.com), the largest contact
network for business professionals in Spain and Latin America with over
835,000 members. Until the takeover, 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 the 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 AG has secured clear
market leadership over its global competitors.

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 Premium Membership.

The multilingualism of Neurona — the site is available in Spanish, Italian
and English — coupled with the wide base of active members in Spain and
Latin America are positive factors in the planned integration onto the XING
platform. 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. The actual
integration on to the XING platform is scheduled to begin at the end of
2007 and is expected to be completed within a twelve-month period.

All parties involved in the acquisition have agreed not to disclose
financial terms of the transaction.
