          GENESYS ANNOUNCES FIRST-QUARTER PRELIMINARY UNAUDITED RESULTS
                        FOR GENESYS, VIALOG AND COMBINED;

                          SIGNIFICANT NEW BUSINESS WIN
               WITH MAJOR GLOBAL AND US TELECOMMUNICATION CARRIER


Montpellier, France--May 3, 2001--Genesys Conferencing (Euronext: 3955 and
Nasdaq: GNSY), the world's leading conferencing specialist, today announced
preliminary unaudited results for the first quarter ended March 31, 2001, for
Genesys and Vialog Corporation independently, and as combined companies. The
results are based on U.S. GAAP; results presented under French GAAP do not
present any material differences. The Vialog acquisition was completed on April
25 and will be consolidated from May 1, 2001.

Organic Growth and Automation Boost First-Quarter Revenues

Genesys revenues for the first quarter increased 32% to Euros 27.0 million (U.S.
$24.9 million) from Euros 20.5 million (U.S. $18.9 million). Vialog revenues
grew 19% to Euros 24.8 million (U.S. $22.9 million) from Euros 20.8 million
(U.S. $19.2 million). The combined growth of both companies was 26% to Euros
51.8 million (U.S. $47.8 million). Europe represented 27% of the combined
revenues, while the United States represented 70% and Asia-Pacific 3%. Growth
was mainly organic, and both companies saw increased use of automated services
which accounted for 44,6%% of Genesys revenues, 26,3% for GCI (Genesys' US
subsidiary) and 23,5% for Vialog at the end of March 2001.

The preliminary unaudited results reflect a gross margin of 59.5% of Genesys'
first-quarter revenues -compared with 55.9% for the first quarter 2000, and
53.8% for Vialog for the first quarter, compared with 51.1% for the first
quarter 2000, and a combined gross margin for the first quarter of 56.8%. The
gross margin increase is primarily attributable to the increased usage of
automated services, which generate higher margins.

Continuous improvement of EBITDA

The preliminary unaudited results reflect a combined Genesys and Vialog' EBITDA
for the first quarter, excluding corporate expenses, of Euros 13.4 million (U.S.
$12.4 million), which represents 25.8% of combined revenues up from a combined
24% for the comparable period last year. Corporate expenses represented 15.5% of
Genesys-only revenues and 8.1% of combined revenues showing the results of cost
control efforts.

Combined EBITDA after corporate expenses is approximately Euros 9.2 million
(U.S. $8.5 million), which represents 17.7% of combined revenues.

"We are pleased to announce our first quarter results for both companies and
that we are off to a strong start for the year," said Francois Legros, Genesys'
Chairman and Chief Executive Officer. "First-quarter revenue growth was very
strong and our profitability for the first quarter should be above our
expectations. We are also keeping corporate expenses under strong control and
for the quarter they decreased to 8.1 percent of combined revenues."

Significant contract win with major global and U.S. telecom carrier

Genesys announced that it has signed one of the largest ever outsourcing
contracts for conferencing services with one of the leading global and U.S.
carriers. Under the terms of this two-year contract, Genesys will provide
privately branded services to the carrier's customers with a clear focus on
fully automated services. Volumes are expected to be in the range of 85 to 120
million minutes per year with a ramp up in 2001. Size, technological leadership,
international coverage and customer focus were key factors for Genesys to win
this contract.

Francois Legros noted : "We believe that this is one of the most important
contracts ever awarded to an independent conferencing specialist. It confirms
that the combined company is a formidable competitor for teleconferencing
business worldwide. We are very proud to partner with a leading international
telecom carrier with$19 billion in revenues and over 30 million customers".

Vialog integration progresses according to plans

Genesys also reported that Genesys' U.S. management team was appointed
immediately following the closing of the Vialog acquisition. Kim Mayyasi, former
Chief Executive Officer of Vialog, becomes Chief Executive Officer of Genesys'
North American combined operations, and Margie Medalle, former Chief Executive
Officer of Genesys' North American operations, becomes President and Chief
Operating Officer of the combined operations. Integration teams representing all
functional areas of both companies have been planning integration programs since
November 2000. The integration of the two companies is progressing according to
plans.

Genesys confirmed that Vialog's recent debt refinancing will generate
approximately U.S. $4.5 million of annual cash savings on interest expenses and
that additional annual savings of $2 million are expected to be generated from
operational synergies and the combination of the companies.

Pro Forma First-Quarter Results and Conference Call

Francois Legros also announced that Genesys will report pro forma financial
results for the first quarter on May 15, 2001, followed by a conference call
that will be broadcast simultaneously over the Internet.
