9.8 The Licensee may show limited amounts of Data solely for presentation purposes to prospective joint venturers or prospective assignees of the Licensee with respect to petroleum exploration and production rights in the survey area to which the Data relates, provided that such prospective joint venturers and prospective assignees agree to keep the same confidential and provided further that the Licensee shall not give copies of Data to or allow copying of Data by such prospective joint venturers or assignees. For the avoidance of doubt the Licensee shall not be entitled to make any such Data available to such persons by any electronic means including without limitation by including the same on any web-site or other Internet presence or by making the same available over the Internet, the worldwide web or any other electronic delivery system or computer network; however, Licensee shall be allowed to make limited amounts of the Data available to such persons on computer workstations or similar equipment in Licensee’s offices for presentation and evaluation purposes only, subject to the terms of this Clause. These obligations of the Licensee shall also apply in cases where the Licensee is selling or transferring his business activities and/or his assets relating to Data, partly or in whole, to a Third Party. The Licensee shall procure that any such prospective joint venturer, assignee or Third Party complies with such obligations of confidence. Except as otherwise provided, in order to obtain any additional access to the Data, the prospective joint venturer, assignee or Third Party must purchase a Licence from PGS at the appropriate price.

Any such disclosure of such proprietary working practices, “know-how” or confidential information shall only be made on condition that the recipient of such information agrees in writing to keep the same strictly confidential in terms reasonably acceptable to PGS provided always however that this clause shall not apply in respect of information which is already in the public domain otherwise than as a result of any breach by Licensee of this Article.

ARTICLE 10 — BONA FIDE GROUP

10.1 In the event that Licensee is or becomes a member of a Bona Fide Group whose interests include part or the whole of the area covered by Data delivered under this Agreement, Licensee shall:

(a) notify PGS of the identity of the other Group Members;

(b) pay the Uplift Payment in accordance with an Appendix if applicable to PGS Proprietary Data.

10.2 The Licensee may disclose and make copies of the Data and information derived therefrom available to the other Group Members subject to the Licensee having complied with its obligations under Clause 10.1 and procuring that the other Group Member(s) agree to comply with the terms of this Agreement and shall confirm this in writing to PGS in such terms as PGS may request. For the avoidance of doubt, licences issued for MegaSurvey data are single company licences and clauses relating to Bone Fide Groups under this article are not applicable; however, if an Uplift Payment has been paid as part of an Appendix concerning licensing of MegaSurvey data and thus Licensee has a full licence to the PGS Proprietary Data involved, the terms of this article will apply to the data for which an Uplift Payment has been made.

10.3 Licensee shall pay to PGS a fee in respect of each Group Member in accordance with the price and the escalation fee applicable at that time. Such fee shall be paid regardless of whether or not the Group Members make themselves acquainted with the Data or any information derived therefrom. If a Group Member already is in possession of the Data pursuant to a valid licence from PGS, no fee shall be payable by Licensee for such Group Member.

10.4 No refund of paid fees will be made by PGS if a Group Member should be in possession of the Data according to a separate licence agreement with PGS.

10.5 Licensee has the right to include new partners as Group Members in a production licence applicable to area(s) covered by Data delivered under the Agreement, provided that the terms of this Article 10 are being observed and the fee applicable to Group Members at that time is being paid by Licensee in accordance with Clause 10.3 above.

10.6 For the new members of a Bona Fide Group, the fee to be paid by Licensee according to Clause 10.3 above shall be based on the fee applicable to Group Members at the time the member is included in the Bona Fide Group.

10.7 A Group Member which has been given access to the Data or any information derived therefrom in accordance with the provisions of this Article, shall have the same rights and obligations related to the use of the Data or such information as the Licensee has under this Agreement.

10.8 The liability hereunder of the Licensee and any other Group Members of a Bona Fide Group of which the Licensee is a member shall be joint and several.

10.9 The Licensee shall promptly inform PGS if a Group Member should leave the Bona Fide Group. The leaving member and any Affiliate thereof shall have no continuing right to make use of the Data or any information derived therefrom received under this Agreement unless it concludes a separate licence agreement with PGS and pays the licence fee in full according to current price lists prevailing at such time. If such agreement with PGS is not concluded, the Licensee shall ensure that all copies of the Data and any information derived therefrom which the leaving member or any Affiliate thereof may have received under this Agreement are returned forthwith to PGS. For the avoidance of doubt, where a Bona Fide Group of which the Licensee is a member ceases to exist, whether as a result of the termination or expiry of any agreement relating to the creation of such Bona Fide Group or otherwise howsoever, all Group Members of such Bona Fide Group at such time (other than the Licensee) shall be deemed to have left the Bona Fide Group and accordingly shall be regarded as leaving members under this Article 10.9.

10.10 If the leaving member should leave the Bona Fide Group prior to a licence round for which the Data have been licensed by the Bona Fide Group and the leaving member elects not to continue use of the Data under a separate licence agreement with PGS, then the Licensee shall ensure that all copies of the Data and any information derived therefrom are returned to PGS.

Agreement shall not affect the rights of the Parties to payment hereunder accrued up to the date of termination.

ARTICLE 12 — CHANGE OF CONTROL

12.1 PGS shall be entitled to terminate this Agreement forthwith by notice in writing to the Licensee if any change occurs in the control of the Licensee or any holding company of the Licensee, or any assignee of the Licensee as provided in Article 13, whether by virtue of any merger, acquisition, consolidation, buy-out or otherwise howsoever, unless:

(i) PGS has given its prior written consent to such change of control and the Licensee and Third Party has complied with any conditions attached to that consent; or

(ii) the successor who acquires control is not a PGS competitor and Licensee within thirty (30) days after such change of control pays to PGS, the fee which would be payable by a third party for licensing the Data up to a limit as described in the appendix; or

PGS’s consent will not be delayed or refused for a single one time assignment to an entity that acquires all or substantially all of the business or assets of the Licensee which occurs prior to 16^th December 2006, and the assignee is not a PGS Competitor or a North Sea Participant. This applies to licences for MegaSurvey data only.

13.4 Except as otherwise authorised herein, this Agreement shall not be construed as granting to the Licensee a right to assign or transfer this Agreement to a Third Party with whom the Licensee has agreed to sell or transfer all or a portion of its petroleum exploration assets and/or business operations, unless such Third Party is not a PGS Competitor and within thirty (30) days after such assignment Licensee pays to PGS, a transfer fee equivalent to the then current fee which would be payable by a third party for licensing the Data up to a limit as described in the appendix.

ARTICLE 16 — WAIVER

16.1 The rights herein given to either Party may be exercised from time to time, singularly or in combination, and the waiver of one or more of such rights shall not be deemed to be a waiver of such right in the future or of any one or more of the other rights which the exercising Party may have.

16.2 The failure of either Party to insist upon the strict performance by the other Party of any term, provision or condition of this Agreement shall not be construed as a waiver or relinquishment in the future of the same or any other term, provision or condition hereof.

17.1 If due to a change in any applicable law or due to a decision or any other act by any competent authority, one or more terms or provisions of this Agreement can no longer be enforced or an amendment of one or more of the provisions of this Agreement is required, the Parties agree that they shall endeavour to find an alternative solution approaching as near as possible the contractual situation existing prior to such a change, decision or act.

17.2 If one or more provisions of the Agreement are determined to be invalid or unenforceable, the remaining provisions shall not be affected thereby, and the Agreement shall be administered as though the invalid or non enforceable provisions were not a part of the Agreement.
