2002 TO ANNOUNCE THE NEW NAME AND LOGO FOR THE COMBINED COMPANY.

                                     * * * *


                                   [VGS LOGO]

                 VERITAS GEO-SERVICES SELECTED AS NEW BRAND NAME
                        FOR COMBINED VERITAS, PGS COMPANY
           New name and logo effective with completion of combination

HOUSTON, TX AND OSLO, NORWAY - JUNE 26, 2002 - Veritas DGC Inc. (NYSE & TSE:
VTS) and Petroleum Geo-Services ASA ("PGS") (NYSE: PGO, OSE: PGS) today
announced a new brand name and logo for the proposed combination of the
companies, to become effective upon the completion of their previously announced
merger. The parent company will be VGS Inc., a newly formed Cayman Islands
company. This new company will be represented as "Veritas Geo-Services,"
utilizing a new logo that incorporates the current PGS graphics with the letters
"VGS," in a new color scheme.

Marketing executives of both companies said the goal in deciding upon a new name
was to capture existing brand equities of both organizations while creating a
singular identity for the combined company. Dennis Jordhoy, vice president of
corporate marketing for Veritas and Sverre Strandenes, senior vice president of
corporate profiling for PGS, said in a joint statement, "Veritas Geo-Services
will be the second largest geophysical services and production company in the
world. We want to build a distinctive new brand for the company while leveraging
the market recognition and reputation of both the Veritas and PGS brands. This
reflects our intent to deliver the best of both organizations to our combined
customer base."

On June 21, the two companies announced an amendment to their agreement
originally reached last November. The companies expect to complete the
transaction in the late third quarter or early fourth quarter this year.

Veritas DGC Inc. offers the oil and gas industry a comprehensive suite of
integrated geophysical services designed to manage exploration risk and enhance
drilling and production success worldwide. These services include seismic data
acquisition in all environments, data processing, data visualization, data
interpretation, reservoir characterization, and extensive non-exclusive seismic
data library surveys worldwide. With over 36 years of operating experience,
Veritas is one of the world's leading providers of advanced geophysical
technologies.

Petroleum Geo-Services is a technologically focused oilfield service company
principally involved in two businesses: Geophysical Operations and Production
Operations. PGS acquires, processes and markets 3D, time-lapse and
multi-component seismic data. This data is used by oil and gas companies in the
exploration for new reserves, the development of existing reservoirs, and the
management of producing oil and gas fields. PGS' advanced geophysical
technologies allow oil and gas companies to better characterize and monitor
their reservoirs in order to enhance production and ultimate recovery of
hydrocarbons. In its Production Operations business, PGS owns four floating
production, storage and offloading systems


("FPSOs") and operates numerous offshore production facilities for oil and gas
companies. FPSOs permit oil and gas companies to produce from offshore fields
more quickly and cost effectively. PGS operates on a worldwide basis with
headquarters in Oslo, Norway and Houston, Texas.
