     PGS' 2000 revenues were $906.2 million, 15 percent higher than in the prior
     year.

     The company employs about 5,500 people of diverse technical backgrounds and
     nationalities. Headquarters are in Oslo, Norway, and Houston, Texas.

OPERATIONS

     The company's core expertise includes developing and operating high-tech
     vessels; on-board and in-sea electronics; data transmission and processing;
     commercial geoscience operations; reservoir evaluation, and petroleum data
     management.

     Supporting the geophysical services activities are PGS Research, a seismic
     research and development group, and PGS Data Processing, which is
     responsible for processing behind the Ramform seismic vessels, reservoir
     services vessels, and onshore seismic equipment. The Data Processing group
     also markets PGS' proprietary processing capabilities and data processing
     centers worldwide.

     PGS' Ramform acquisition technology includes six vessels that can tow up to

      Ramform Challenger

      Ramform Valiant

      Ramform Viking

      Ramform Victory

      Ramform Vanguard

FPSO FLEET

     PGS' FPSO fleet consists of four vessels:

      PETROJARL I: A purpose-built, turret-moored production vessel that can be
      used in full field development, extended well test or early production
      mode. It has serviced nine fields since 1986 and conducted more than 1,300
      offloadings without a reportable environmental incident.

      PETROJARL FOINAVEN: A turret-moored, converted submarine tender that has
      achieved an exceptional record of production uptime in harsh environments,
      and was certified to ISO 14001 standards for environmental procedures and
      performance. It has conducted more than 500 offloadings.

      PETROJARL VARG: A purpose-built, double-hulled vessel that is the newest
      addition to PGS fleet of high-specification FPSOs. It has a production
      capacity of 60,000 bopd and storage capacity of 470,000 bbls, making this

(Editorial Backgrounder)

                      PGS, VERITAS MERGER TO CREATE STRONG,
                               DIVERSE COMPETITOR


The seismic industry today is undergoing a shift that is unprecedented in recent
years. Increased competition, the need for more and improved data resources, and
an ongoing requirement for increasingly advanced technology have ushered in a
new era of service. The implications of this business climate are clear: Any
company that wants to succeed must be able to deliver on every demand the market
and its customers set.

By that standard - and many others - the proposed merger of equals between
Petroleum Geo-Services and Veritas more than meets the test. It brings together
a pair of proven companies whose complementary services will create a strong No.
2 in the seismic industry, not only positioning the new firm as a high-profile
player but also reshaping the competitive marketplace in a way that is expected
to benefit customers and shareholders alike.

EXPANDED RESOURCES AND CAPABILITIES

PGS, headquartered in Oslo and Houston, Texas, is a technically focused oilfield
service company that is primarily involved in two businesses: the acquisition,
processing, and marketing of time-lapse and multi-component seismic data that is
used by oil and gas companies to explore new reserves, develop existing
reservoirs, and manage producing oil and gas fields; and production services, in
which the company owns four floating production, storage and offloading systems
(FPSO) and operates nine offshore production facilities for oil and gas
companies. The FPSOs enable oil and gas firms to produce faster and more
efficiently from offshore fields.

Houston-based Veritas is a leading provider of services designed to help
customers manage exploration risk and improve drilling and production success.
Its capabilities include seismic survey planning and design, seismic data
acquisition, data processing, data visualization, reservoir characterization,
and extensive non-exclusive seismic data library surveys worldwide. Its
libraries consist of 3.6 million line kilometers of seismic marine and land
data, more than 90 percent of which is three-dimensional.

The combined company will be able to build on the respective strengths of both
PGS and Veritas to create a $1.5 billion entity whose balanced mix of services -
two-thirds geophysical, one-third production - will enable it to compete
effectively and efficiently against any competitor. Its strengthened position in

the seismic industry will be further enhanced by a broader set of capabilities
and resources that include:

     An expanded fleet of 21-vessels, equipped with some of the most
     sophisticated technology in the world;

     83,000 channels in its land operations;

     27 seismic processing centers;

     400,000 square kilometers of data in its library, and

     The ability to combine shallow water and transition zone (marches, tidal
     basins, etc.) capabilities with a strong 3D capability.

Taken collectively, these advantages will enable the new company to provide
turnkey services and greater flexibility to customers, and put it in a position
to serve most of the major areas in the world more efficiently than either could
have done as separate entities.


SOUND RATIONALE

Ownership of the new company will be made up of 60 percent PGS and 40 percent
Veritas. While this may raise some questions in financial circles as to a
premium being paid by Veritas shareholders, there is a sound rationale behind
the transaction.

First and foremost, there can be little argument that the new company will
compete more effectively than either PGS or Veritas individually, and its
21-vessel fleet will allow for a more global reach. Beyond that, the more
balanced business mix will diversify the revenue and cash flow streams, while
more predictable FPSO earnings are expected to offset any fluctuations of the
multi-client seismic business. This latter point is of great value to Veritas
shareholders, who will effectively be getting 40 percent of the less cyclical,
$500 million per year FPSO business.

Although the 40-60 percent ratio may suggest to some that Veritas shareholders
are paying a premium at the outset, that ratio is actually consistent with a
number of factors. These include the three-month average market price; the
market prices when negotiations began, and the relative contributions of each
company to the new organization. Additionally, PGS is undervalued relative to
Veritas and is selling at only half of its book price, while Veritas was
receiving a higher relative valuation in the marketplace. The fact that
shareholders can expect to benefit significantly from the combined advantages of
both companies - including greater size and stability and a stronger market
presence - will also largely minimize potential concerns over dilution of
Veritas's value.

Nor are any problems anticipated by Veritas' assumption of $2.4 billion of PGS
debt. Veritas closely examined the liquidity and cash resources of the combined
company over the next few years, and concluded that the resources will be
available to effectively execute the necessary business plan. PGS's sale of
Atlantis, part of its non-seismic portfolio, is expected to yield $200 million,
and the FPSO assets are expected to continue to deliver strong operating cash
flows. The debt issue is further addressed by the improved competitive position
of the new company, as well as its initial $1.5 billion in combined revenues.

That having been said, debt reduction will remain a high priority for the new
company, which will seek to reduce its current debt-to-capital rate of 49
percent to approximately 40 percent during the next two years.

WHAT LIES AHEAD

The merger is expected to close in April 2002, and must pass regulatory review
in the U.S., South America and Europe. It must also get the support of a
majority of Veritas shareholders and 90 percent of PGS shareholders. The boards
of both companies have already unanimously approved the transaction, and PGS and
Veritas officials believe that shareholders will follow suit once they
understand the value and benefits of the transaction. Both companies are also
confident that regulatory bodies will view this transaction favorably.

Once approved, the new company will have its operational headquarters in
Houston. Reidar Michaelson, the chairman and CEO of PGS, will serve as chairman
and co-CEO in charge of production services; Dave Robson, who is chairman and
CEO of Veritas, will serve as vice chairman and co-CEO responsible for
geophysical services. Each company will contribute four members to and will
mutually agree on an additional two directors for the board of 10. The renamed
new company will be publicly traded on The New York Stock Exchange and will
pursue listings on the Toronto and Oslo stock exchanges.

PRESS RELEASE - PGS & VTS TO MERGE
11/26/2001  07:00:00 PM

--------------------------------------------------------------------------------

Houston, TX and Oslo, Norway, November 26, 2001 - Petroleum Geo-Services ASA
("PGS") (NYSE: PGO, OSE: PGS) and Veritas DGC Inc. (NYSE & TSE: VTS) today
announced that their boards of directors have unanimously approved a definitive
agreement to combine the two companies in a merger of equals. The combination
will create the second largest company in the geophysical services industry with
an equity market capitalization of approximately $1.0 billion and a total
enterprise value of approximately $3.5 billion. The transaction is anticipated
to be immediately accretive to the combined company's earnings and cash flow per
share.

The new company will offer a full range of integrated marine and land
geophysical services and floating production operations. Benefits from the
merger include:

o   Leading presence in global marine and land seismic markets

o   Largest, newest and most geographically diverse seismic library with over
    400,000 square kilometers of modern 3D data

o   More flexible, technologically advanced and efficient seismic fleet

o   Owner and operator of four high-tech floating production, storage and
    offloading (FPSO) vessels

o   Operator of more than 20 production installations in the North Sea,
    including six floaters

o   Broader geographic scope in seismic acquisition capabilities

o   Significant leading-edge data-processing, interpretation and reservoir
    technologies

o   Initial estimated annual cost savings of at least $35 million

o   More stable and diversified cash flow stream

o   Improved liquidity and enhanced financial flexibility

In a joint statement, Reidar Michaelsen, Chairman and Chief Executive Officer of
PGS, and Dave Robson, Chairman and Chief Executive Officer of Veritas, said,
"Growing global demand for reliable seismic data coupled with ongoing
consolidation, both among our customers and in our industry, make this an
opportune time for this combination. By combining our complementary,
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
in active and highly prospective areas around the world. Our combination will
also create a more versatile marine seismic acquisition fleet that is second to
none, with the ability to provide data acquisition services anywhere, at any
time.

We are excited about the tremendous upside potential this transaction creates
for the combined company and its shareholders, customers and employees. The
combination of Veritas and PGS will enable us to offer fully integrated services
to our customers and will give us the strength, flexibility and resources to
compete more effectively and efficiently on a broader global scale. Our combined
company will also possess the depth of talent and financial strength to pursue
exciting new growth opportunities around the world.

INDUSTRY-LEADING PORTFOLIO

The combined company will boast an industry-leading portfolio including:

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
comprised of ten directors, four designated from each of the two companies,
including Mr. Robson and Mr. Michaelsen, and two newly appointed unaffiliated
directors.

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.

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.

Merrill Lynch & Co. and ABG Sundal Collier & Co. acted as financial advisors,
and Merrill Lynch provided a fairness opinion to PGS. Baker Botts LLP and
Wikborg, Rein & Co. acted as PGS' legal advisors. Evercore Partners Inc.
acted as financial advisor and provided a fairness opinion to Veritas and

DAVE ROBSON ANNOUNCES VERITAS AND PGS TO MERGE - WORD DOCUMENT
11/26/2001 05:17:00 PM


Dear fellow employees:

I am please to announce an exciting event that will be very important to our
future and to our long-term success. The Boards of Directors of Veritas and PGS
have today approved a definitive agreement to combine the two companies in a
merger of equals. The press release that provides more details is available on
the Veritas Bulletin Board, the Internet and our website and will be posted at
all of our operating locations. Please review it carefully.

The Transaction

The combined company will be the second largest geophysical contractor in the
world. In addition, the Floating Production, Storage and Offloading (FPSO)
business owned by PGS will add significantly to the new company's profits and
cash flow. We will be a much larger company in the oilfield service area with
total sales in excess of $1.5 billion, offices in over 30 countries and about
10,000 employees. About 7000 of these employees will work in the combined
geophysical operation. Operationally, we will have 21 marine vessels, capacity
for more than 20 land crews, 27 processing centers and 36 locations.

We are planning to rename the company which involves assuming a new name,
creating a new logo and developing a branding/advertising program with new
graphics, etc. The reason for the new name is to create a spirit of cooperation
within the new entity.

The company will be more global in nature and better equipped to service our
customers. We can be more cost efficient because we can spread our overhead over
a larger revenue base. We will have significantly enhanced research and
development efforts in areas like data processing and acquisition technology to
improve our technology to even higher levels. When you look at the combined
strengths of the two companies, we are leading the industry in most areas of
operational excellence and technology.

The company will be organized into two areas, Production Services ( FPSO's) and
Geophysical. I will be Co-CEO responsible for the Geophysical Division and
Reidar Michaelson will be Co-CEO responsible for Production Services.

The Board of Directors will be composed of four current members of both Veritas
and PGS's Boards along with two new independent members to be selected. The
Company will be listed on the New York Stock Exchange and the Toronto Stock
Exchange. The head office will be in Houston, Texas and will be located at 10300
Town Park, the current headquarters for the Veritas company, and this will
happen as soon as practical. Organizational plans beyond this point have not
been solidified at this time. We will keep you informed as we proceed.

We are estimating consolidation savings of $35 million as a result of the
merger. Due to the many steps and procedures required for a merger of this size,
we do not expect to complete the deal until April 2002. In the meantime, we have
to operate separately. However, extensive due diligence will commence and
organizational planning will start in earnest immediately.

Why are we doing this

The geophysical industry currently is not a growth industry. The only way to
achieve our goal of providing opportunities for our employees to grow and for
our shareholders to have a decent return on their investment is to consolidate.
We have been having discussion with others but clearly PGS was the most
interested in such a plan. To capitalize on such an opportunity, there must be
both a need and a willingness to change. The geophysical industry needs more
consolidation to meet the challenges of investing large sums of capital in
research and development, in multi-client data libraries and in a never-ending
series of new technological advances in acquisition and processing capabilities.
The geophysical industry is now expected to provide leadership in many areas of
geophysical technology which were traditionally the domain of our customers, the
oil companies. At the same time, we need to deliver more value to our customers
and provide a reasonable return on the total capital entrusted to us. The
following are some of the reasons that this transaction makes sense:

      ONE. We will be able to optimize the deployment of more assets in more
combined areas. This will reduce mobilization costs, allow us to focus the right
assets and the right people on the right jobs and give us the ability to tackle
increasingly complex challenges for our customers.

      TWO.  Combining our respective asset bases will give us the opportunity
to focus our capital expenditures and ensure full utilization of all of our
assets in a global market.

      THREE. While maintaining our investment in R&D, we can broaden the scope
for new technological innovations that have made PGS and Veritas leaders in
providing better solutions to our customers.

      FOUR. Together, we have the largest database in the world of modern 3D
seismic data, totaling over 400,000 square kilometers. Our customers will
benefit from our integration of these datasets and our making them available to
a worldwide market.

      FIVE. We will capitalize on the synergies between the FPSO business and
the seismic business. Seismic technology and our combined reservoir knowledge
can help exploit reserves in and around marginal fields produced by FPSO's while
the FPSO's provide more stable and predictable cash flow streams to offset the
traditional, more volatile seismic business.

What this means to you

Over the next couple of years, we will be consolidating operations that are
duplicative to the new company. There may be some disruption to you if you are
in one of these areas. Obviously, one of the advantages to a merger like this is
to eliminate duplication. However, we do not have significant overlap in general
and therefore layoffs will be minimal. Notice that we are not making any public
announcements regarding the number of jobs lost for these reasons. Most everyone
in the new company is a essential employee. In other words, if a hand on the
back deck of a boat is not working, we can't deploy our cables, if a data
processor isn't working, we can't produce sections for our customers. Our job is
to produce product for our customers. That activity must go on uninterrupted.
Therefore, if you are doing a good job, you should have little cause for
concern.

We will be communicating with you on a regular basis as this transaction
evolves. Later this week, a Lotus Notes database ( Operations Advantage ) will
be available so that you may post issues and concerns and view the answers to
frequently asked questions. In addition, the senior management of the company
and of your division has been briefed to the extent that we can. We will try to
see as many of you in person as is practical between now and the end of the
year. In the meantime, video conferencing meetings are scheduled this week to
many different locations.

Finally, in situations like this, gossip and rumors tend to take a little
information and expand upon it significantly. Please visit with your supervisors
and senior management to seek further information. In the short term, they may
not be more informed than you are, but the presidents of all of the divisions
have been briefed to the extent that we have clear information. Please show
professionalism as you deal with limited information and please do not share any
information with the geophysical community if it is not factual.


Sincerely,



Dave Robson

---------------------------------------------------

A critical step in the merger process is creating a structure for the new
organization. At this time it has been determined that the business will be
divided into two major units: seismic services and FPSO (Floating Production
Storage and Offloading) systems. In the seismic services or geophysical business
unit we must now determine an organization design and subsequently decide who
will be placed in the leadership roles for our various seismic businesses. This
process will begin shortly and will be completed after the first of the new
year.

Once finalized, these decisions will be communicated by organizational
announcement and will also be placed in this database.

WHO IS THE WINNER IN THIS MERGER
11/27/2001  12:00:10 PM

---------------------------------------------------

     Both companies and their customers and shareholders are winners in this
merger. This is a "merger of equals" that will create the second largest company
in the geophysical industry. Each company will bring extensive resources and
libraries of seismic data, sophisticated software, and extraordinary people to
the new organization. Remember that each company will be equally represented on
the board of directors and Dave Robson will be the leader of geophysical
operations.

HOW LONG WILL IT TAKE TO COMPLETE THE MERGER
11/27/2001  12:57:12 PM

---------------------------------------------------

Completing the merger is a complicated process that requires the approval of
shareholders of both companies and approvals of a number of regulatory agencies
in the U.S. and other countries. While there is no way to predict exactly when
the merger will close, we do expect to complete it sometime in April of 2002.

Others have asked if is possible that Veritas and PGS will not get the
appropriate approvals to complete the merger. The boards of both companies are
convinced of the merger's value, and they are communicating the strategic
business rationale to all audiences and shareholders. While it is possible that
the merger will not receive the necessary approvals, we believe that is
unlikely.
