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.
