CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING INFORMATION

Certain statements herein contained are forward-looking statements within the
meaning of the "safe harbor" provisions of the Private Securities Litigation
Reform Act of 1995. These statements are based on management's current
expectations and beliefs and are subject to a number of factors and
uncertainties that could cause actual results to differ materially from those
described in the forward-looking statements. The forward-looking statements
contained herein include statements about future financial and operating results
of the combined company, including the accretiveness and estimated cost savings
of the transaction, the financial position of the combined company after
completion of the transaction, and the timing and other benefits of the
transaction. These statements are not guarantees of future performance, involve
certain risks, uncertainties, and assumptions that are difficult to predict, and
are based upon assumptions as to future events that may not prove accurate.

Therefore, actual outcomes and results may differ materially from what is
expressed herein. In any forward-looking statement in which PGS or Veritas
expresses an expectation or belief as to future results, such expectation or
belief is expressed in good faith and is believed to have a reasonable basis,
but there can be no assurance that the statement or expectation or belief will
result or be achieved or accomplished. The following factors, among others,
could cause actual results to differ materially from those described in the
forward-looking statements: the risk that PGS and Veritas' businesses will not
be integrated successfully; costs related to the proposed transaction; failure
of Veritas stockholders to approve the proposed transaction; failure of a
sufficient number of PGS shareholders to exchange their shares for the new
holding company's shares; failure of other closing conditions to be satisfied
and other economic, business, competitive and/or regulatory factors affecting
PGS and Veritas' businesses generally, including prices of oil and natural gas
and expectations about future prices, as set forth in PGS and Veritas' filings
with the SEC, including their most recent Annual Reports on Form 20-F (PGS) or
Form 10-K (Veritas), especially in the Management's Discussion and Analysis
section, PGS' most recent Reports on Form 6-K and Veritas' most recent Quarterly
Reports on Form 10-Q and Current Reports on Form 8-K. PGS and Veritas are under
no obligation to (and expressly disclaim any such obligation to) update or alter
their forward-looking statements whether as a result of new information, future
events or otherwise.

                                     * * * *

THE FOLLOWING PRESS RELEASE WAS ISSUED JOINTLY BY VERITAS AND PGS ON JULY 22,
2002 TO ANNOUNCE THE EXECUTION OF A SECOND AMENDMENT TO THE MERGER AGREEMENT.

[PGS LOGO]                                                        [VERITAS LOGO]



                     VERITAS DGC AND PETROLEUM GEO-SERVICES
                    SIGN SECOND AMENDMENT TO MERGER AGREEMENT


HOUSTON, TX AND OSLO, NORWAY - JULY 22, 2002 - Veritas DGC Inc. ("Veritas")
(NYSE & TSE: VTS) and Petroleum Geo-Services ASA ("PGS") (NYSE: PGO, OSE: PGS)
today announced that the two companies have signed an amendment to their pending
merger agreement to combine the two companies. Veritas and PGS said that as a
result of receiving notification from the staff of the Securities and Exchange
Commission ("SEC") that the Form S-4 registration statement and proxy statement
for the transaction would not be reviewed, the parties agreed to postpone a five
business day period during which either side could terminate the transaction
from a period tied to finalizing the SEC review and comment process to the five
business days ending August 15, 2002.

The amendment announced today relates to the parties' right to terminate the
transaction upon a payment of $7.5 million, if one of the following events has
not occurred: a) sale of the Atlantis subsidiary for at least $195 million; or
b) receipt of a commitment for the placement or sale of equity or equity-linked
securities that will yield proceeds to the new company of at least $200 million;
or c) sale by PGS of other assets for at least $200 million, or d) a combination
of equity commitments or asset sales of at least $200 million. Consequently, if
neither party elects to exercise its termination right, the transaction will
proceed even though none of the above events has occurred. In that case, the
mailing of the relevant disclosure materials to the shareholders of Veritas and
PGS would be made shortly after August 15, 2002. The transaction remains
conditioned upon, among other things, the approval of a majority of Veritas
shareholders, listing of the new holding company's shares on the NYSE and
customary regulatory approvals, most of which have already been obtained. The
transaction also requires 90 percent of PGS shareholders to exchange their
shares for the new holding company's shares.

Commenting on the amendment, CEOs Dave Robson of Veritas and Reidar Michaelson
of PGS, "While we are pleased with the SEC's early response, the companies have
not yet had adequate time to explore the availability to the combined company of
additional financial resources. To this end, we are currently evaluating several
financing alternatives. While we have made great progress thus far, we have not
finalized our plans. Therefore, both managements felt it prudent to extend the
decision period until August. We remain convinced that the industrial logic
behind this combination is extremely positive to both our companies."

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.

In connection with the proposed combination transaction, Veritas and a newly
formed holding company will file a proxy statement/prospectus with the
Securities and Exchange Commission (the "SEC"), and with respect to the proposed
exchange offer for PGS shares, Veritas and the new holding company will file a
Tender Offer Statement on Schedule TO, which will include a related prospectus,
and PGS will file a Solicitation/Recommendation Statement on Schedule 14D-9.
