high-quality seismic data libraries, we will be uniquely positioned to offer our
customers a much broader array of sophisticated 2D, 3D and 4D geophysical data

     o    400,000 square kilometers of modern 3D data

     o    21 marine seismic crews

     o    83,000 land seismic channels capable of fielding 25 to 30 high-tech 3D
          crews

     o    4 high-tech, harsh environment FPSO vessels

     o    More than 20 data processing centers

     o    8 data visualization centers

HEADQUARTERS, MANAGEMENT AND BOARD

The combined company will be headquartered in Houston, Texas and will maintain a
significant operating presence in Norway. Upon completion of the transaction,
Mr. Michaelsen will serve as Chairman and Co-CEO of the combined company, with
primary responsibility for the production business. Mr. Robson will become Vice
Chairman and Co-CEO of the combined company, with primary responsibility for the
geophysical business. The combined company's Board of Directors will be

including Mr. Robson and Mr. Michaelsen, and two newly appointed unaffiliated

COST SAVINGS

The companies expect to achieve annual pre-tax cost savings of at least $35
million. Savings are expected to come from the elimination of duplicative
general and administrative and operating activities, improved operating
efficiencies and the optimization of research and development efforts.

TERMS AND CONDITIONS

Under the terms of the agreement, both Veritas and PGS will become wholly-owned
subsidiaries of a new holding company incorporated in the Cayman Islands. PGS
shareholders who exchange their shares will receive 0.47 shares of the new
holding company's common stock for each share of PGS they own. Veritas
shareholders will receive one share of the new holding company's common stock
for each share of Veritas they own. Based upon the closing stock prices of
Veritas and PGS on Friday, November 23, 2001, this represents a value of $7.64
per PGS share, or a 44 percent premium to PGS shares. The transaction is
expected to be tax-free to Veritas shareholders. The transaction is expected to
be taxable to PGS shareholders; however, PGS expects to apply for tax-exempt
treatment for Norwegian shareholders of PGS. At inception, PGS shareholders will
own approximately 60 percent of the new holding company and Veritas shareholders
will own approximately 40 percent.

period, listing of the new holding company's shares on the NYSE and customary
regulatory approvals. The transaction also requires 90 percent of PGS
shareholders to exchange their shares for the new holding company's ordinary
shares. The companies expect that the transaction can be completed in the second
quarter of 2002. The new company also intends to pursue the listing of its
shares on the Oslo and Toronto stock exchanges.
