used, as for the trade name, as the corporate title by Havas Advertising.

WHEREAS since June 6, 2001, Vivendi Universal Publishing (formerly Havas S.A.)
is no longer a shareholder of Havas Advertising. The latter wishing to use,
throughout its entire Group, the name Havas, the Parties agreed to sell to Havas

NOW, THEREFORE, THE PARTIES HERETO HEREBY AGREE AS FOLLOWS:
----------------------------------------------------------

The Seller agrees to ensure that the companies of the Havas Group, whose
corporate title still includes the name Havas, stop using such name, in any form
whatsoever, and remove the trademarks listed in annex 2 hereto, within six (6)
months after the final completion of the sale. The Seller furthermore agrees to
remove all trademarks including the name Havas that are not mentioned in annexes
1 and 3 hereof but brought to the attention of any Party hereto after the
signing hereof.

The Buyer acknowledges and accepts that the following rights granted to third
parties by the Seller's Group exist and are exercised:

- the right granted to Potel & Chabot to use the "Espace Charles-Louis Havas"
trade name, the reception center thus named is in the office building located at
136 avenue Charles de Gaulles in Neuilly-sur-Seine;

- the right contributed to Agence Havas Marocaine to use the name "Havas Agence"
in Morocco.

Furthermore, and to avoid any risk of confusion with business conducted over the
past few years by the Seller's Group under the Havas trade name and its
different variations, the Buyer agrees, from the date hereof and until June 30,
2003, not to use directly or indirectly:

                                       2

Line, Havas Overseas trade names;

- any of the Trademarks in the following fields: publishing books, newspapers

It is expressly agreed that Vivendi Universal and Vivendi Universal Publishing

from classes 16, 35 and 38. It is however noted that such removal shall not
prevent the buyer or the franchisee of the Havas Voyages Trademarks, in
connection with business that comes under class 39, to use the Havas Voyages
Trademarks on tangible or intangible media, which by their nature come under
classes 16, 35 or 38, such as, for example, paper or on-line travel brochures or
catalogues, except for any business likely to compete with the Buyer's business.

registration number 544692, Greek registration number 113781, Japanese
registration number 3039408, European Community registration number 00831503)
for class 39 services, for the purpose of protecting or defending, if necessary,
its rights and those of Vivendi Universal with respect to the Havas Voyages
Trademarks;

- that Vivendi Universal and Vivendi Universal Publishing agrees not to sell or
license the Havas Voyages Trademarks to any person plainly liable to damage or
undermine the image or reputation of the Havas trade name.

- that the Seller shall, before final completion of the sale, remove all the
Trademarks from class 39, and that, failing this, the Buyer shall cause them to
be removed as quickly as possible after the final completion of the sale;

- that the Buyer agrees not to use directly or indirectly the Havas trade name,
alone or combined with other elements, to conduct, in France or abroad, travel
or tourist agent business, be it in developing, organizing and selling for
business or private individual travelers and, in particular, taking orders,
