INTRODUCTORY MATERS

2013 FIRST HALF RESULTS

Forward-Looking Information This document contains certain forward-looking statements which speak only as of the date on which they are made. Forward-looking statements relate to projections, anticipated events or trends, future plans and strategies, and reflect Havas’ current views about future events. They are therefore subject to inherent risks and uncertainties that may cause Havas’ actual results to differ materially from those expressed in any forward-looking statement. Factors that could cause actual results to differ materially from expected results include changes in the global economic environment or in the business environment, and in factors such as competition and market regulation. For more information regarding risk factors relevant to Havas, please see Havas’ filings with the Autorité des Marchés Financiers (documents in French) and, up to October 2006, with the U.S. Securities and Exchange Commission (documents in English only). Havas does not intend, and disclaims any duty or obligation, to update or revise any forward-looking statements contained in this document to reflect new information, future events or otherwise. Net New Business Net new business represents the estimated annual advertising budgets for new business wins (which includes new clients, clients retained after a competitive review, and new product or brand expansions for existing clients) less the estimated annual advertising budgets for lost accounts. Havas' management uses net new business as a measurement of the effectiveness of its client development and retention efforts. Net new business is not an accurate predictor of future revenues, since what constitutes new business or lost business is subject to differing judgments, the amounts associated with individual business wins and losses depend on estimated client budgets, clients may not spend as much as they budget, the timing of budgeted expenditures is uncertain, and the amount of budgeted expenditures that translate into revenues depends on the nature of the expenditures and the applicable fee structures. In addition, Havas' guidelines for determining the amount of new business wins and lost business may differ from those employed by other companies. The average net debt (quarterly, semi-annually and annually) is calculated as the difference between the structured gross debt under IFRS (OBSAAR, Eurobond, used credit lines, etc…) and the cash in bank and cash equivalents measured on a daily basis for the main countries integrated in the International cashpool; for the other countries, the average net debt taken into account is the monthly average net debt. The new definition excludes earn-out and buy-out obligations and includes blocked current accounts relating to employee profit-sharing.
