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.

Merger Update 1/10/02

The merger planning process began in earnest on January 3, with two days of
meetings and presentations in Houston with the corporate groups of both
companies. The meetings were designed to introduce the people and philosophy of
each company to their counterparts, as well as to senior management.

Further meetings are planned over the next month to introduce the management of
the operational groups to each other, and to encourage discussion between the
groups. This process helps the groups meet each other on a personal level, and
will lay the groundwork for more detailed organizational planning which will
begin after these introductory sessions.

The meeting schedule is as follows:
