Shareholders' equity and liabilities As of 30 September 2005 net financial debt totalled 98.9 million for shareholders' equity of 139.2 million at 30 June 2005, with no material changes occurring since on the basis of the most recent available financial information. Information on the company's businesses Created in 1978, under the name Polygone Services, GL events is today a global provider servicing all participants of the event industry: organizers, communications agencies, companies, institutions, etc. In close partnership with its clients, the group assists them from the design to implementation of their projects. In the event communications market, the principal participants include: Organizers, communications agencies Service providers Venues: exhibition centres, convention centres, concert halls, auditoriums and theatres, stadiums, etc. The most important remains the end customer: corporations, local governments/administrations, associations. The end customer may in turn select: one of the other event industry players while assuring the coordination; any of these players to assure the comprehensive management of the event. In this environment GL events has reinforced its historical expertise in event industry services by developing a portfolio of venues (convention centres, exhibitions centres, Zenith concert halls) and event engineering services to provide organizers global solutions. Today the group offers an extensive range of venues and associated services. Material changes since 30 June 2005 Since 30 June 2005, there have been no known changes in the group's financial and commercial situation. Strategy GL events goal is to become the leading integrated international provider of solutions for events by 2008. This goal will be achieved by integrating new fields of expertise, to complete its global offering and a by streamlining its organization to support two strategic business units, Global Services and Venue and Event Management. The goal of this strategy, in conjunction with continued expansion through organic growth and targeted acquisitions, is to achieve sales by 2008 approaching 700 million. By this date, Venue and Event Management and international markets should each account for respectively for 50% of group sales. Organic growth should benefit from increasing contributions from venues added to the group's portfolio in recent years. It should also be driven by calls for tenders as concession agreements for venues in France and other countries are renewed in the years ahead. Venue and Event Management should in turn fuel the growth of Global Services. In response to the group's excellent performance in the 2005 third quarter, management raised the full year sales guidance to 422 million from its initial guidance of 410 million. 5

Growth through strategic acquisitions will focus on four areas: - geographical expansion to strengthen expertise developed by Global Services offered through the existing network, - adding new areas of expertise, - developing high value-added services such as organizing conventions of events in France and Europe, - adding new international venues to the group's existing portfolio. The group's expansion will generate synergies both from the complementary nature of its two strategic business units and the development of its network enabling customers to benefit from an increasing choice of venues and services in France and other countries. The increasing contribution by Venue and Event Management to sales should also significantly enhance group earnings by 2008. Through this strategy combining continued organic growth with targeted acquisitions, the group should attain sales in 2008 approaching 700 million. Use of proceeds The purpose of the issue is to strengthen GL Events financial structure and, in line with the group s strategy, provide resources to actively pursue targeted acquisitions in the four areas defined above.
