(other than the payment by the registrant of expenses incurred or paid by a director, officer, or
controlling person of the registrant in the successful defense of any action, suit or proceeding)
is asserted by such director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter has been settled
by controlling precedent, submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities Act and will be
governed by the final adjudication of such issue.

Item 6.
Indemnification of Directors and Officers
Norwegian law provides that a director or the chief executive officer of a Norwegian company
is liable for any loss or damage he has intentionally or negligently caused the company in the
performance of his duties. The shareholders may, by a majority resolution at a general meeting,
decide either to bring a claim against, or to discharge from liability, such director or chief
executive officer. Notwithstanding a decision at the general meeting to discharge a person from
liability or to reject a proposal to hold a person liable, shareholders owning at least 10% of the
share capital, or at least 10% the total number of shareholders, may within a limited period of
time bring a claim predicated on such liability on behalf of the company.
In addition, PGS has entered into indemnification agreements with each of its directors. Each
agreement provides that, in the event that such director was, is or becomes a party to any pending
or completed action, suit or proceeding, or any inquiry or investigation that leads to the
institution of any such action, suit or proceeding, by reason of or arising out of any event or
occurrence relating to anything done or not done by such director in the
II-1
capacity as a director of PGS, then PGS will indemnify such director against any and all
expenses, judgments, fines and amounts paid in settlement to the extent permitted by applicable
law. The obligation of PGS is subject to the condition that the claim is not a result of gross
negligence or willful misconduct on the part of the director. If requested by a director, PGS will
advance expenses to such director.
PGS also has directors and officers liability insurance that would indemnify its directors and
officers against damages arising out of certain kinds of claims that might be made against them
based on their negligent acts or omissions while acting in their capacity as directors and
officers.

Item 9.
Undertakings
(a) The undersigned registrant hereby undertakes:
(1)
To file, during any period in which offers or sales are being made, a
post-effective amendment to this Registration Statement:
(i)
To include any prospectus required by Section 10(a)(3) of the Securities
Act;
(ii)
To reflect in the prospectus any facts or events arising after the
effective date of this Registration Statement (or the most recent post-effective
amendment thereof) which, individually or in the aggregate, represent a fundamental
change in the information set forth in the Registration Statement. Notwithstanding
the foregoing, any increase or decrease in volume of securities offered (if the
total dollar value of securities offered would not exceed that which was registered)
and any deviation from the low or high end of the estimated maximum offering range
may be reflected in the form of prospectus filed with the Commission pursuant to
Rule 424(b) of the Securities Act if, in the aggregate, the changes in volume and
price represent no more than a 20% change in the maximum aggregate offering price
set forth in the "Calculation of Registration Fee" table in the effective
Registration Statement; and
II-2
(iii)
To include any material information with respect to the plan of
distribution not previously disclosed in this Registration Statement or any material
change to such information in this Registration Statement;
provided, however,
that the undertakings set forth in paragraphs (a)(1)(i) and (a)(1)(ii)
above do not apply if the information required to be included in a post-effective amendment
by those paragraphs is contained in periodic reports filed by the registrant pursuant to
Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in this
Registration Statement.
(2)
That, for the purpose of determining any liability under the Securities Act, each
such post-effective amendment shall be deemed to be a new registration statement relating to
the securities offered therein, and the offering of such securities at that time shall be
deemed to be the initial
bona fide
offering thereof.
(3)
To remove from registration by means of a post-effective amendment any of the
securities being registered which remain unsold at the termination of the offering.
(b) The undersigned registrant hereby undertakes that, for purposes of determining any
liability under the Securities Act, each filing of the registrant's annual report pursuant to
Section 13(a) or Section 15(d) of the Exchange Act that is incorporated by reference in this
Registration Statement shall be deemed to be a new registration statement relating to the
securities offered therein, and the offering of such securities at that time shall be deemed to be
the initial
bona fide
offering thereof.
(c) Insofar as indemnification for liabilities arising under the Securities Act may be
permitted to directors, officers, and controlling persons of the registrant pursuant to the
foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the
Commission such indemnification is against public policy as expressed in the Securities Act and is,
therefore, unenforceable. In the event that a claim for indemnification against such liabilities
(other than the payment by the registrant of expenses incurred or paid by a director, officer, or
controlling person of the registrant in the successful defense of any action, suit or proceeding)
is asserted by such director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter has been settled
by controlling precedent, submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Securities Act and will be
governed by the final adjudication of such issue.
