> ANALYSIS OF THE CHANGEOVER FROM FRENCH GAAP TO BACKGROUND In accordance with EC regulation 1606/2002 of 19 July 2002 of international accounting standards, GL events group consolidated statements for the period ending 31 December 2005 will be prepared according to IAS/ applicable as of 31 December 2005 as approved by the European Union. The first complete statements to be published according to these new accounting standards will be for the 2005 period with a comparison for 2004 established on the basis of the same standards, including IAS 32 and IAS 39. In light of the publication of a comparison for 2004, and the recommendation of the French market authorities (AMF) concerning disclosures during the transition period, GL events has produced a report for 2004 for the changeover to IAS/ presenting the forecasted impact of on: The balance sheet on the transition date of 1 January 2004, on which the final impact of the transition will be recorded under shareholders' equity when the 2005 consolidated statements are published; an analysis at 31 December 2004 of the balance sheet prepared on the basis of French GAAP vs. ; an analysis of the interim income statement at 30 June 2004 prepared on the basis of French GAAP vs. ; an analysis of the 2004 income statement prepared on the basis of French GAAP vs. ; an analysis of the interim cash flow statements at 30 June 2004 prepared on the basis of French GAAP vs. ; an analysis of the cash flow statement at 31 December 2004 prepared on the basis of French GAAP vs. ; an analysis of the shareholders' equity changes statement at 1 January 2004 prepared on the basis of French GAAP vs.. The statements prepared for the purposes of comparison have been reviewed by the Audit Committee and audited by the Statutory Auditors. PRINCIPLES RETAINED TO PREPARE THE GROUP S FIRST FINANCIAL STATEMENTS IN ACCORDANCE WITH The preparation of 2004 information has been based on standards and interpretations published at 31 December 2004 and adopted by the European Union in addition to the optional provisions retained by Management of GL events. The optional provisions retained by Management and exemptions used are those GL events expects to adopt for its first consolidated annual statements in 2005 under. Subsequent changes of in 2005 that might be introduced could nevertheless result in modifications to the opening balance sheet of 1 January 2004 and the 2004 statements restated according to when the 2005 consolidated statements are published. For 2004 information, GL events has applied all / IFRIC standards and interpretations whose application is mandatory as of 1 January 2005 and in advance for standards IAS 32 and IAS 39 concerning instruments starting 1 January 2004. For the treatment of public service management contracts and venue concessions for exhibitions centers, the standard is still under discussion. Because the IFRIC has published draft interpretations on 3 March 2005 for the treatment of these activities, final approval by the IASB is expected in the second half of 2005. At present, the treatment of public service management and concession agreements of the Group does not fall under the scope of this standard. Pending the

> ANALYSIS OF THE CHANGEOVER FROM FRENCH GAAP TO publication of the final interpretations of the IFRIC, GL events has opted to maintain, at this stage, in the balance sheets prepared on a basis of at 1 January 2004 and 31 December 2004, the accounting policies it currently applies in its statements prepared in accordance with French GAAP, i.e. along the lines of an operating lease. Restatements in connection with the first-time application of IAS / As provided for under 1 First-time application of international reporting standards, for its opening balance sheet, the Group has decided to: - continue to apply historical costs for noncurrent assets and in consequence not proceed with their remeasurement; - apply IAS 32 and 39 on instruments as of the 2004 year; - restate business combinations occurring prior to 1 January 2004 ; - opt for the elimination of translation s at 1 January 2004, relating to translation into euros of the statements of subsidiaries with a another operating currency. - apply 2 share-based payment for plans implemented after 7 November 2002. Impact of the changeover to IAS / The principal impact of the application of the new standards, beyond changes of form in the presentation of statements, is relatively limited and concern: - goodwill that as of 1 January 2004 will no longer be amortized; - the cancellation of deferred expenses. Presentation of principal changes made pursuant to the application of IAS / IAS 1 - Presentation of statements GL events has decided to apply the recommendations of the of the national French accounting body (Conseil National de la Comptabilité) 2004-R.02 of 27 October 2004 concerning the presentation of the statement, cash flow statement and changes in shareholders' equity statement. This recommendation is in compliance with the principles set forth in IAS 1 Presentation of Financial Statements. Income statement Given business practice and the nature of the activity, the presentation of the income statement by nature of income and expenses, considered preferable to presentation by function, was maintained. Key modifications having an impact on the income statement are: - the notion of operating profit and current operating profit, whereby the difference between is that other operating income expenses must include only a very limited number of items, unusual and infrequent involving a significant amount, generally subject to disclosures; - the elimination of extraordinary items. Balance sheet The principal changes include: - the breakdown of assets between current and noncurrent; - the inclusion of minority interests in shareholders' equity. Cash flow statement No modifications resulting from the change in accounting standards have been made to net cash as the only differences in relation to the previous presentation concerned reclassifications and the introduction of further detail.

> ANALYSIS OF THE CHANGEOVER FROM FRENCH GAAP TO 3 Business combinations Goodwill recorded on consolidation under French GAAP is included with other goodwill. The revised IAS 36 eliminates the amortization of goodwill that is instead henceforth tested annually for impairment (and whenever there is evidence of impairment) for intangible assets with unspecified lifespans and for goodwill resulting from a business combination. The amortization recorded under French GAAP for 2004 was accordingly reversed under. As indicated in note 1 of the "Methods of Valuation" of the consolidated statements (page 64 of the 2004 annual report), impairment tests for intangible assets are carried out on the basis of the discounted cash flow method previously implemented by the Group. IAS 38 - Intangible assets Pre-opening and start up costs that do not meet the criteria under IAS 38 to be capitalized are expensed. Under French GAAP, the expenses were capitalized and amortized over a period of three to five years. The net value at 1 January 2004 of pre-opening and start up expenses were eliminated by a charge to shareholders equity. The treatment is identical for deferred expenses that do not meet the criteria under IAS 38 to be capitalized. IAS 16 Property, Plant, equipment Property, plant, equipment continue to be recorded in the balance sheet at their historical acquisition cost. They are accordingly not subject to remeasurement. In light of procedures applied in prior years, the application of IAS 16 Property, Plant, Equipment has no impact on the Group statements. 2 Stock-options 2 Stock-Based Payment, published in February 2004, concerns the transactions carried out with personnel or other third parties or involving shares. Its application to GL events concerns solely Stock options granted to personnel. As allowed for under this standard, only options granted starting 7 November 2002 have been taken into account. IAS 39 Financial instruments Financial instruments are recorded at fair value. Out of the total instruments used by the group, a single fair value hedge qualified as speculative in respect to IAS 39 was identified. In consequence, gains or losses on remeasurement to fair value are recorded under net profit or loss for the period. The other instruments are cash flow hedges whose fluctuations in value will be recognized as changes in reserves for the effective portion and as changes in the income statement for the ineffective portion.
