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 Licensed 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 Licensed 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 Licensed Data, the prospective joint venturer, assignee or Third Party must purchase a Licence from PGS at the appropriate price. 8.9 The Licensee may disclose and provide copy of the Licensed Data to other parties, subject to written agreement by PGS, provided that such other parties agree to keep such Licensed Data within the confidentiality obligations herein. 7 8.10 If Licensed Data delivered under the Agreement are reprocessed by or for the Licensee, the confidentiality terms contained herein shall apply to the results of the reprocessing and the information derived therefrom. Magnetic media and hard copies, resulting from reprocessing, shall be marked by such notice as PGS may require from time to time. Without prejudice to the generality of the foregoing on the termination or expiry of this Agreement for whatever reason The Licensee shall immediately cease to make any use of such reprocessed Data or the information derived therefrom and shall at the option of PGS, either destroy or return to PGS such reprocessed Data and all copies of any information derived therefrom. 8.11 The Licensee shall not divulge any of PGS's proprietary working practices "know-how" or other confidential information relating to PGS or its business to any Third Party except pursuant to the extent permitted under Articles 8.2, 8.5 and 8.6 and in any event only as may be strictly necessary. 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 the Licensee of this Article. ARTICLE 9 - BONA FIDE GROUP 9.1 In the event that the Licensee is or becomes a member of a Bona Fide Group whose interests include part or the whole of the area covered by Licensed Data delivered under this Agreement, The Licensee shall: (a) notify PGS of the identity of the other Group Members; (b) pay the Uplift Payment in accordance with Clause 5.2 if applicable to PGS Proprietary Data. 9.2 The Licensee may disclose and make copies of the Licensed Data and information derived therefrom available to the other Group Members subject to the Licensee having complied with its obligations under Clause 9.1 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. 9.3 Subject to the Licensee having paid any applicable Uplift Payment due under Clause 9.1, a Group Member with whom the Licensee has entered into a joint venture or other contractual arrangement providing for joint contractual or equity interests in all or part of any license covered by the Licensed Data shall be entitled to receive from PGS a license to the relevant Licensed Data at no additional charge, where the Group Member complies with the requirements set out in Article 9.3(i) and 9.3(ii) below or, where applicable on open file or brokeraged data, subject to that Group Member having paid an amount to PGS equivalent to any brokerage payment that PGS may be liable to pay to a third party in respect of granting such a licence to the Group Member. The licence granted by PGS to Group Member will include data over the equity licence acreage, plus a reasonable (approximate 2 km) periphery. (i) where the licence is a UKCS licence, such Group Member has not held an interest in more than 2 licences in the area covered by the Data prior to the UK's 21st licensing round or (ii) where the licence is a Norway licence, such Group Member does not currently hold an equity licence in Norway as of the Commencement Date. 8 9.4 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 Licensed Data or such information as the Licensee has under this Agreement. 9.5 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. 9.6 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 Licensed 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 Licensed 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 9.6. 9.7 If the leaving member should leave the Bona Fide Group prior to a licence round for which the Licensed Data have been licensed by the Bona Fide Group and the leaving member elects not to continue use of the Licensed Data under a separate licence agreement with PGS, then the Licensee shall ensure that all copies of the Licensed Data and any information derived therefrom are returned to PGS and the information derived therefrom. ARTICLE 10 - TERM AND TERMINATION 10.1 This Agreement shall be in effect from the Commencement Date and shall continue in effect for an indefinite period of time until it is terminated according to the provisions contained in this Article or by mutual agreement between the Parties. 10.2 This Agreement shall terminate in the event that the Licensee fails to comply with its obligations under the Main Agreement, and such failure continues for a period of five (5) Working Days after written notice of such failure from PGS. For the avoidance of doubt and without prejudice to the generality of the foregoing, it is acknowledged and agreed that this Agreement shall automatically terminate in the circumstances set out in Clause 3.9 of the Main Agreement. 10.3 Either Party may by notice in writing to the other Party terminate this Agreement with immediate effect if: (i) the other Party should fail to comply with any material term or provision of this Agreement and such breach or default of this Agreement is not remediable or not remedied within 30 days after receipt of written notice of such breach or default from the non-defaulting Party. (ii) the other Party commits a persistent breach of this Agreement (and for the purposes hereof a persistent breach shall be a breach which is committed more than three (3) times in any six (6) month period in respect of which written notice is given each such time by the Party not in default); or 9 (iii) the other Party goes into liquidation either compulsory or voluntary (save for the purpose of a bona fide solvent reconstruction or amalgamation) or if a receiver or manager is appointed in respect of the whole or any part of its assets or if any resolution is passed for the voluntary liquidation of the other Party or if any petition is presented to any court of competent jurisdiction for the compulsory liquidation of the other Party or if any petition is presented to any court of competent jurisdiction for the administration of the other Party pursuant to Part II of the Insolvency Act 1986 or if the other Party proposes any voluntary arrangement pursuant to Part I of the Insolvency Act 1986 or if any arrangement, scheme of arrangement or compromise or composition is proposed with the general body of creditors of the other Party or any part of the same or if the other Party makes an assignment for the benefit of or composition with its creditors generally or threatens to do any of these things or if the other Party shall become insolvent by reason of its inability to pay its debts as they fall due or if anything analogous to the forgoing occurs in any relevant jurisdiction. 10.4 Upon termination of this Agreement all use, whether by The Licensee, any Affiliate of The Licensee, any Consultant or any Group Member, of the Data licensed hereunder and any material or information derived therefrom shall immediately cease and all copies of such Data in the possession or control of such persons shall forthwith be returned by the Licensee to PGS and all copies of any material or information derived therefrom shall forthwith be destroyed. 10.5 All provisions of this Agreement which in order to give effect to their meaning need to survive its termination including without limitation the Licensee's obligations with respect to confidentiality and the provisions of Articles 6, 7 and 8 shall remain in full force and effect thereafter. Termination of this Agreement shall not affect the rights of the Parties to payment hereunder accrued up to the date of termination. 10.6 The foregoing rights of termination shall apply notwithstanding any assignment, novation, transfer or other grant of rights whatsoever (whether or not permitted hereunder or approved by PGS) and the above provisions shall be binding on any successor, assign or sub-licensee of the rights of the Licensee hereunder. ARTICLE 11 - CHANGE OF CONTROL 11.1 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 12, 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 of USD 2.25 million (USD2,250,000); or (iii) a one time change of control occurs as part of the Vespa Arrangements (as defined in the Main Agreement), or (iv) there is a one time change of control which occurs after the Vespa Arrangements and PGS has not issued a Put Notice under Clause 3 of the Main Agreement, and which occurs within three (3) years of the Commencement Date, and the successor who acquires control is not a PGS Competitor or a North Sea Participant. 10 11.2 Licensee shall in any event notify PGS in writing of any change in control of the Licensee or its holding company or their permitted assignees to whom rights have been assigned under Article 12 no later than seven (7) days after such change taking place and any regulatory restrictions on such notification being made having expired. 11.3 For the purpose of this Article, "control" in relation to a company or corporation shall mean the right to exercise directly or in directly the vote in a general meeting of more than 50 per cent of the voting shares in such company or corporation in issue from time to time and/or the right to control the composition of the board of directors of such company or corporation and "holding company" shall have the meaning ascribed thereto by Section 736 Companies Act 1985. 11.4 Nothing in this Clause shall affect PGS's rights to terminate this Agreement under or pursuant to Clause 10.2. ARTICLE 12 - ASSIGNMENT 12.1 The Licensee may not assign or transfer any of its rights or obligations hereunder, except as expressly authorised herein. 12.2 The rights of the Licensee granted by this Agreement may not be transferred without the prior written consent of PGS. PGS's consent will not be delayed or refused for: (a) a single one time assignment to an entity that acquires all or substantially all of the business or assets of the Licensee which occurs after the Vespa Arrangements and PGS has not issued a Put Notice under Clause 3 of the Main Agreement, and which occurs within three (3) years of the Commencement Date, and the assignee is not a PGS Competitor or a North Sea Participant; (b) an assignment to Vespa or any of its Affiliates, provided that the Licensee shall procure that the entity to whom Licensee assigns its rights under this Agreement shall agree to assign such rights back to Vespa immediately prior to ceasing to be an Affiliate of Vespa. 12.3 A transfer of the right to use the Licensed Data shall not release the Licensee from obligations under this Agreement including its obligations to pay Uplift Payments and in the event the entity to which the Data is transferred or its Affiliates is or becomes the holder of an exploration or production licence in an area covered by PGS Proprietary Data or becomes a Group Member of a Bona Fide Group that holds or has an interest in an exploration or production licence over an area covered by such Data. 12.4 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 Licensee, 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 of USD2.25 million (USD2,250,000). 12.5 PGS may assign or transfer its rights and obligations hereunder, wholly or in part, to any of its Affiliates; however, PGS shall remain primarily liable for its obligations hereunder if such assignment or transfer is made without the prior written consent of Licensee. Such assignment shall always be notified to Licensee in writing, covering the Licence Agreement valid at the time of Assignment. 11 ARTICLE 13 - NOTICE 13.1 Any notice required or permitted to be given under this Agreement shall be in writing and shall either be delivered personally or sent by recognised courier service or by pre-paid registered mail or by facsimile (telefax) transmission to the Parties as follows: To: PGS Exploration (UK) Ltd PGS Court Halfway Green Walton-on-Thames Surrey KT12 1RS Tel.: +44 (0)1932 26 00 01 Fax: +44 (0)1932 26 65 12 To: NSNV, Inc. 1001 Fannin, Suite 1700 Houston, Texas 77002 United States Tel.: (713) 307-8700 Fax: (713) 307-8794 or to such other addresses as either of the Parties may from time to time designate by notice in writing to the other Party. 13.2 A notice given hereunder shall be deemed to have been received by the Party as follows: (i) if personally delivered, at the time of delivery (ii) if delivered by courier, two days after the notice was delivered to the courier (iii) if sent by pre-paid registered mail, four days after the envelope containing the notice was delivered into the custody of the postal authorities (iv) if sent by facsimile transmission, at the time of transmission, provided always that a confirmation copy is sent by pre-paid registered mail to the relevant Party within 24 hours after transmission unless such date of deemed receipt is not a business day, in which case the date of deemed receipt shall be the next succeeding business day. In this Article "business day" shall mean any day (other than a Saturday or Sunday) on which banks in the territory in which the Party on whom notice is being served is situated are generally open for business. In proving such service, it shall be sufficient to prove that delivery was made to the Party or to the courier, or that the envelope containing the notice was properly addressed and delivered into the custody of the postal authorities as prepaid registered mail or that the facsimile transmission was properly addressed, transmitted and received as the case may be. ARTICLE 14 - FORCE MAJEURE 14.1 If a Party is prevented or delayed in the performance of any of its obligations under this Agreement by force majeure, and if it gives written notice thereof to the other Party 12 specifying the matters constituting force majeure, together with such evidence as it reasonably can give and specifying the period for which it is estimated that such prevention or delay will continue then the Party giving notice shall be excused the performance or the punctual performance, as the case may be (except for the payment of money) of such obligations from the date of such notice and for so long as such cause or prevention or delay shall continue. 14.2 For the purposes of this Agreement "force majeure" shall be deemed to be any cause affecting any performance of this Agreement arising from or attributable to acts, events, omissions or accidents beyond the reasonable control of a Party and without limiting the generality thereof shall include the following: 14.2.1 strikes, lockouts or other industrial actions; 14.2.2 civil commotion, riots, invasions, war, threat or preparation for war; 14.2.3 fire, explosion, storm, flood, earthquake, subsidence, epidemic or other natural physical disaster. ARTICLE 15 - WAIVER 15.1 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. 15.2 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. ARTICLE 16 - SEVERABILITY 16.1 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. 16.2 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. ARTICLE 17 - ENTIRE AGREEMENT, AMENDMENTS 17.1 This Agreement and the Definitive Agreement constitute the entire agreement of the Parties with respect to the subject matter hereof and supersedes all prior or contemporaneous written or oral understandings, agreements or representations (including any made negligently but excluding any made fraudulently) other than those contained herein. There are no understandings or agreements relative to this Agreement that are not fully expressed herein. 17.2 No modification, amendment or addition to the Agreement shall be valid and binding on the Parties, unless set forth in writing and signed by the Parties. 13 ARTICLE 18 - CONTRACTS (RIGHTS OF THIRD PARTIES) ACT 1999 18.1 Subject to Article 18.3, the Parties intend that no provision of this Agreement shall confer any benefit nor be enforceable by any person who is not a party to this Agreement by virtue of the Contracts (Rights of Third Parties) Act 1999. 18.2 Subject to the remaining provisions of this Agreement, Articles 2, 6, 7.4, 8, 9 and 10.3 are intended to be enforceable by any Owner by virtue of the Contracts (Rights of Third Parties) Act 1999. 18.3 Notwithstanding Article 18.2, this Agreement may be rescinded, amended or varied by the Parties to this Agreement without notice to or the consent of any Owner. ARTICLE 19 - GOVERNING LAW, DISPUTES 19.1 The Agreement shall be governed by and construed in accordance with the laws of England and Wales. 19.2 All disputes and differences that may arise out of or in connection with the Agreement will be settled as far as possible by means of negotiations and conciliation between the Parties. 19.3 In case of failure to reach an amicable settlement, any dispute, controversy or claim arising out of or in any way connected with this Agreement including any question regarding its existence, validity or termination shall be conclusively resolved by arbitration in London under the Rules of the London Court of International Arbitration (LCIA) which Rules are deemed to be incorporated by reference into this Article. 19.4 The Parties agree to submit to the exclusive jurisdiction of the courts of England and Wales for the purpose of any interim relief from a court if necessary to prevent serious and/or irreparable injury to that Party where the Licence Agreement has been terminated and PGS considers it necessary to seek relief from the Courts for the purpose of protecting it or the Owner's proprietary interests in the Data.

These will include: 1. All the Deliverables for the Standard Delivery Items. Note that well data in Norway are supplied by Aceca, rather then by IHS. The horizons for Norway CNS will be identical as for the CNS UK. The horizons for Norway South Viking Graben and Northern North Sea will have the same major horizons with possible adjustments for local sequence boundaries. 2. The Optional Delivery Items will be available for all 10 of the options listed for the CNS UK survey. The pricing will be the same as quoted for CNS UK. For Norway CNS, Horizon Attribute Package, Depth Attributes Package and ER Mapper Package Options will be very similar to the CNS UK. For Norway South Viking Graben and Northern North Sea, the Horizon Attributes Package, Depth Attributes Package and ER Mapper Package Options will be provided, but the detail of which attributes will be made will vary according to the geology of each area. PGS intends to have all deliverables completed by end Q.1 2004. PGS to supply detailed lists of Norway deliverables once these are available. 24 APPENDIX C TO THE LICENCE AGREEMENT UPLIFT PAYMENTS 1.
