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.

At inception, PGS shareholders will own approximately 60 percent of the new holding company and Veritas shareholders will own approximately 40 percent.

The transaction is conditioned upon, among other things, the approval of a majority of Veritas shareholders, expiration of the Hart-Scott-Rodino waiting 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.
